As described above, the background technology related to the mobile communication device that can receive both the communication service and the broadcast service has been overviewed. As seen in Patent Document 1 and Patent Document 2, in the mobile communication device, Has a universal problem of how portable (small and lightweight) is and how long power can be secured for its operation. For this reason, there is a strong demand for the direction of development of a small, lightweight, and high-performance battery and the direction of power saving of the device itself.
Accordingly, when considering a mobile communication device equipped with a digital broadcast receiving function, it is conceived that both a communication function such as a telephone call and an e-mail and a broadcast receiving function such as a TV reception are operating separately.
In the communication function, as a basic function for realizing mobile communication, the mobile communication device periodically performs position registration and standby operation with the mobile communication network. As is well known, in a plurality of base stations constituting a mobile communication network, each base station transmits radio waves constituting an area capable of wireless communication to communicate with a mobile communication device. The mobile communication device receives the control signal transmitted by each base power, recognizes that it is within the area of the base station emitting the radio wave with the strongest reception strength, When recognizing that the base station for communication has changed due to movement, location registration control is performed, and newly located base station information is registered in a location registration database installed in the network. On the other hand, when a call arrives at the mobile communication device, the communication control device in the network refers to the location registration database to identify the base station where the mobile communication device to be received is located, and Instruct the station to call the target mobile communication device. Upon receiving this instruction, the base station transmits a paging signal with information for identifying the mobile communication device on the control signal and transmits it within its own area. Therefore, the mobile communication device receives this control signal as a standby operation, and periodically monitors the presence or absence of a call to the own device. When the mobile communication device receives and detects a call signal to which identification information identifying its own device is added, it accepts the incoming call in response.
Such location registration control and standby operation as a communication function of the mobile communication device are performed regardless of the broadcast function of TV reception.
On the other hand, when receiving a TV broadcast, the user concentrates on viewing the content, so the user does not actively use the communication function and is almost in a standby state.
As described above, in the mobile communication device in which the broadcast reception function and the communication function are merged, when receiving the broadcast, a plurality of receivers are operated although the reception methods are different, and it is devised in terms of power saving of the device. There is room for. In addition, when viewing the broadcast, since it is connected to both the broadcast network and the mobile communication network, there is room for improvement in terms of effective use of the frequency.
In addition, although there is disclosure of an invention related to delivery of electronic mail via a broadcasting network as described in Patent Document 4, the broadcasting network is organically fused with the mobile communication network to save the mobile communication device. There is no disclosure of technology to increase power consumption.

The mobile communication standby system and the mobile communication device according to the present invention are intended to save power in a mobile communication device in which a mobile communication function and a digital broadcast receiving function represented by terrestrial digital broadcasting are mounted together. To do. In the mobile communication device combined with the digital broadcast receiving function represented by terrestrial digital broadcasting, the present invention stops the standby operation performed via the mobile communication network when receiving the digital broadcast. Provided are a mobile communication standby system and a mobile communication apparatus thereof that achieve power saving by a configuration that performs a standby operation using a data broadcasting function.
The mobile communication standby system according to the present invention is configured as follows.
It has a digital broadcast reception function and a mobile communication function, registers a digital broadcast reception request in the digital broadcast network before receiving the digital broadcast, and registers the broadcast reception information in the mobile communication network during the digital broadcast reception. A mobile communication device and a control device installed in the mobile communication network, and when there is an incoming call addressed to the mobile communication device, the broadcast receiving information related to the mobile communication device is not registered. A first control device for informing incoming notification information from a station and transferring incoming notification information to a digital broadcast network when broadcast receiving information is registered, and a control device installed in the digital broadcast network, When receiving incoming call notification information related to the mobile communication device from the first control device, the second control for delivering the incoming communication information transferred to the broadcast content distributed to the mobile communication device. The mobile communication device stops the standby operation by receiving the notification signal notified from the base station during reception of the digital broadcast, and based on the incoming notification information distributed on the broadcast content It is characterized by identifying an incoming call.
Then, when the mobile communication device that has identified the incoming call call based on the incoming call notification information distributed on the broadcast content responds to the incoming call, the mobile communication device performs a location registration operation in a pseudo manner to generate a response signal. The configuration is such that the data is transferred to the first control device.
At the time of this response, the mobile communication device acquires a time stamp that identifies the interruption point of the broadcast content that was being viewed, and transfers this time stamp together with the response signal to the first control device. Further, it is transferred to the second control device, and the second control device stores the time stamp in correspondence with the identification information of the mobile communication device.
Then, upon receiving notification of the termination of the call of the mobile communication device from the first control device, the second control device resumes the distribution of the broadcast content to the mobile communication device based on the stored time stamp. The configuration to be taken.
In addition, when the electronic mail is distributed, the first control device distributes the electronic mail data from the base station when the broadcast receiving information regarding the mobile communication device is not registered, and the broadcast receiving information is registered. If so, the electronic mail data is transferred to the second control device of the digital broadcasting network. The second control device distributes the e-mail data on the broadcast content distributed to the mobile communication device, so that the mobile communication device receives the notification signal notified from the base station while receiving the digital broadcast. The standby operation by reception is stopped, and the electronic mail data distributed on the broadcast content is received.
In addition, the mobile communication device stops the location registration operation that is performed when it comes to a different base station during reception of the digital broadcast, and information transfer to the mobile communication network is necessary. Then, after receiving the standby channel transmitted by the base station and establishing synchronization with the mobile communication network, the location registration operation is executed in a pseudo manner.
The mobile communication device according to the present invention is a mobile communication device having a digital broadcast receiving function and a mobile communication function, and when the digital broadcast is not received, an incoming call notification is made via the base station of the mobile communication network. It is a mobile communication device that performs a standby operation for identifying the presence / absence of an incoming call and receives an incoming call notification via a digital broadcast network while receiving a digital broadcast.
The mobile communication device includes a data separation unit that identifies information data addressed to the mobile communication device distributed on digital broadcast content and separates it from broadcast data, and an information data type separated by the data separation unit. And when the information data type is distribution start information for notifying the start of broadcast content distribution, a viewing information control unit for instructing to notify the mobile communication network of the broadcast viewing start information, When a notification is instructed, a standby switching control unit is provided that performs a pseudo location registration operation and instructs to transmit the location registration information including the broadcast viewing start information. When the standby switching control unit recognizes that the incoming notification of the mobile communication device in the mobile communication network has been switched to the route to be notified via the digital broadcasting network, the standby switching control unit stops the standby operation performed via the base station. Take the configuration to let you.
When the information data type separated by the data separation unit is an incoming call call notification, the viewing information control unit of the mobile communication device of the present invention displays the incoming call notification via the display unit and responds to the incoming call notification. When the information is received via the operation unit, the transmission of a response signal to the mobile communication network is instructed. When the standby switching control unit is instructed to transmit a response signal to the mobile communication network, the standby switching control unit pseudo-executes the location registration operation and instructs to transmit the location registration information including the response signal. Take the configuration. At this time, the viewing information control unit obtains a time stamp indicating the interruption point of the digital broadcasting being received, and instructs to transmit the response signal to the mobile communication network including the time stamp.
When the information data type separated by the data separation unit is email data, the viewing information control unit stores the email data, displays the email data via the display unit, and stores the email data. Is completed, an instruction to send an e-mail reception completion notification to the mobile communication network is given. When instructed to transmit an e-mail reception completion notification to the mobile communication network, the standby switching control unit executes a location registration operation in a pseudo manner and transmits the location registration information including the e-mail reception completion notification. Instruct.
Furthermore, when the standby switching control unit recognizes that the incoming notification of the mobile communication device in the mobile communication network has been switched to a route to be notified via the digital broadcasting network, the standby switch control unit may be located in a different base station. Stop the location registration operation to be executed when Then, when instructed to transmit notification information to the mobile communication network, the location registration operation is simulated after receiving the standby channel transmitted by the base station and establishing synchronization with the mobile communication network.

DESCRIPTION OF EXEMPLARY EMBODIMENTS Hereinafter, preferred embodiments of the invention will be described with reference to the accompanying drawings.
FIG. 1 is a system configuration diagram of a mobile communication standby system according to an embodiment of the present invention. As shown in FIG. 1, the mobile communication standby system of the present invention is realized by organically connecting a mobile communication network 1 and a digital broadcasting network 2.
The mobile communication network 1 holds and manages base station information in which a plurality of base stations 12 constituting a radio area of the mobile communication network 1 and a mobile communication device 3 in the mobile communication network are located. When there is an incoming call to the registration server 11 or the mobile communication device 3, the incoming notification means 101 for notifying the device of the incoming call, and when the e-mail addressed to the mobile communication device is received, In order to change the mail delivery means 102 for transmitting to the device, and the incoming notification and e-mail delivery addressed to the mobile communication device from the mobile communication network 1 to the notification / delivery route via the digital broadcast network 2 The distribution switching means 103 is included. The incoming call notification means 101, the e-mail delivery means 102, and the delivery switching means 103 are a base station control device (not shown) of the mobile communication network 1 or a mobile switching device as a control device located above the base station 12. It may be a function included in the apparatus.
On the other hand, the digital broadcasting network 2 performs viewing registration for the broadcast content user, stores the viewing registration server 20 for controlling content distribution to the user according to the viewing registration, stores the broadcast content, and broadcasts under the control of the viewing registration server 20. From the content server 21 that outputs the content, the incoming notification notification means 201 that converts the incoming notification information and e-mail information transferred from the mobile communication network 1 to digital data of the digital broadcast, the distribution mail conversion means 202, and the content server 21 A data distribution device 22 that multiplexes and distributes incoming notification information and e-mail information output from the incoming notification conversion means 201 and the distributed mail conversion means 202 to the output broadcast content, and a digital that outputs the distribution data as a digital broadcast wave The broadcast station 23 is included. The incoming call notification conversion unit 201 and the delivery mail conversion unit 202 may be included in the viewing registration server 20.
Next, the operation of the mobile communication standby system according to an embodiment of the present invention will be described.
The operation of the mobile communication standby system according to the present invention is mainly applied to the incoming route notification and e-mail delivery distribution route change setting process, and the incoming e-mail notification and e-mail delivery execution process in such a setting process. Separated.
FIG. 2 is a system configuration diagram for explaining the concept of a mobile communication standby system incoming call notification and e-mail delivery distribution route change setting process according to the present invention. FIG. 2 explains the relationship between the location registration server 11 belonging to the mobile communication network 1 in FIG. 1, the viewing registration server 20 belonging to the digital broadcast network 2, and the mobile communication device 3.
In FIG. 2, the location registration server 11 manages location information of the mobile communication devices 3 belonging to the mobile communication network 1 as a subscriber list 110. On the other hand, the viewing registration server 20 manages, as a user list 210, information related to the mobile communication device 3 that has registered viewing of digital broadcasting. In a state in which the mobile communication device 3 is not registered for viewing digital broadcasting, the location information of the mobile communication device 3 is registered and managed in the subscriber list 110 of the location registration server 11, as described above. It is used for communication control processing (location registration processing, identification of a receiving device, etc.) in a mobile communication network. Also, nothing is registered in the user list 210 of the viewing registration server 20 until there is a usage registration from a viewing requester.
From this state, when the user who owns the mobile communication device 3 wishes to view the digital broadcast, the user for specifying the user together with the desired broadcast content, the viewing start time, etc. by the processing described later. Information and viewing related information for viewing service control are registered in the user list 210 of the viewing registration server 20. Further, in the subscriber list of the location registration server 11, in addition to location information that is normally managed, additional information corresponding to the mobile communication device 3 that has started viewing digital broadcasts by processing to be described later is used for notification of incoming calls and e-mail delivery. Standby control switching information indicating that the distribution path has been changed via the digital broadcasting network 2 is set.
In this way, control information relating to the mobile communication device is registered in the management lists of both the mobile communication network 1 and the digital broadcast network 2, and viewing of the digital broadcast by the mobile communication device 3 is started, and an incoming call notification and electronic After the mail delivery route is transferred to the digital broadcasting network 2, the mobile communication device 3 can stop at least the standby operation via the mobile communication network 1. (Also, the location registration process can be stopped as will be described later.) And, if there is an incoming call or e-mail delivery to the mobile communication device 3 receiving this digital broadcast, the mobile communication device 3 Obtains such information via the digital broadcasting network 2 by processing to be described later.
The details of the operation of the mobile communication standby system according to the present invention will be described with reference to FIGS.
First, a method for changing a delivery route for incoming notification and electronic mail delivery will be described.
First, digital broadcast viewing registration is performed by the user of the mobile communication device 3.
A user of the mobile communication device 3 who wishes to view a digital broadcast accesses the viewing registration server 20 of a business operator that operates the digital broadcast using the mobile communication device, selects a broadcast content to be viewed, and a viewing time. The viewing registration of the information specifying the band and the user is performed. At this time, the mobile communication device 3 may access the viewing registration server 20 via a telephone line from the mobile communication network 1 via the base station 12, or may access from the Internet. (The route from the base station 12 to the viewing registration server 20 in FIG. 1)
The viewing registration server 20 creates and edits viewing-related information necessary for user viewing management based on this viewing registration and sets it in the user list 210. As the viewing-related information, a user code for identifying the user (at least identification information such as a telephone number of the mobile communication device 3, a user name or a management number assigned by the digital broadcaster if necessary) There are a content code for specifying broadcast content to be distributed, a viewing start time, and viewing control information including decryption key information that enables reception only by a specific user. Note that the decryption key information is transmitted to the user's mobile communication device 3 to allow the user to view broadcast content separately distributed.
Next, when the viewing start time (setting information of the user list 210) set at the stage of digital broadcast viewing registration by the user of the mobile communication device 3 is reached, the viewing registration server 20 refers to the user list 210 and responds accordingly. Start distribution control of broadcast content to the user.
First, the viewing registration server 20 notifies the content server 21 of the content codes registered in the user list 210 and instructs the output of the broadcast content corresponding to the content code. On the other hand, the data distribution device 22 is notified of the content code and viewing control information that designates an encryption process that enables viewing only to a specific user who has registered viewing of the broadcast content. The data distribution device 22 encrypts the broadcast content data output from the content server 21 according to the viewing control information notified from the viewing registration server 20, sends it to the digital broadcast station 23 as digital broadcast data, and places it on the broadcast radio wave to the user. To deliver.
At this time, a process of changing and setting the incoming notification of the mobile communication device 3 and the delivery route of the electronic mail delivery via the digital broadcasting network 2 is executed. Therefore, the data distribution device 22 distributes training data for route change setting processing instead of actual broadcast content as digital broadcast data transmitted first from the digital broadcast station 23 (a in FIG. 2).
The mobile communication device 3 that has received broadcast radio waves from the digital broadcast station 23 and is able to view using the decryption key information acquired at the time of viewing registration and has detected the training data is provided in the mobile communication network. 1 is subjected to pseudo location registration processing (b in FIG. 2). This pseudo location registration process uses the same procedure as the normal location registration process, but the standby switching information indicating that “the digital broadcast reception is started and the standby operation is performed via the digital broadcast network 2” is used as the location registration information. Instead, it is sent to a control device (not shown). (At this time, it is possible to add the standby switching information to the location registration information and send it.)
This standby switching information is registered in the subscriber list 110 of the location registration server 11 in association with the location information of the mobile communication device 3.
By the pseudo location registration processing as described above, in the mobile communication network 1, the delivery switching unit 103 sends the incoming notification and e-mail delivery route to the mobile communication device 3, not to the base station 12. This is equivalent to changing to the digital broadcasting network 2.
When the setting by the pseudo location registration processing is completed, the control device of the mobile communication network 1 (not shown) notifies the viewing registration server 20 of the digital broadcast network 2 of an incoming call and electronic mail to the mobile communication device 3. The fact that the switching of the distribution route to the digital broadcasting network 2 is completed is notified (c in FIG. 2).
Upon receiving the route switching completion notification from the mobile communication network 1, the viewing registration server 20, as one of the viewing-related information in the user list, reads “This user's mobile communication device performs a standby operation via the digital broadcast network. Service execution status information indicating “switched” is registered, the training data transmitted for the route change setting process is stopped, and the data distribution apparatus 22 is instructed to distribute the actual broadcast content.
When it is detected that the training data is stopped and the broadcast content can be viewed (d in FIG. 2), the mobile communication device 3 is switched to the standby operation via the digital broadcast network. And the standby operation that has been executed with the mobile communication network 1 is stopped.
In the above description, the mobile communication device 3 that has received the training data transmitted from the digital broadcasting network 2 executes a pseudo location registration process, so that the delivery route for incoming notification and e-mail delivery is digitally changed. Although the change setting process is performed via the broadcast network 2, the viewing registration server 20 may notify the control device (not shown) of the mobile communication network 1 directly.
In this case, when the viewing start time reserved by the user is reached, the viewing registration server 20 uses the identification information (for example, telephone number) of the mobile communication device 3 registered as the user information of the user managed in the user list as a key. As information, a setting request is made to change the distribution route via the digital broadcasting network 2 (dashed line A in FIG. 2). When the control device (not shown) of the mobile communication network 1 receives this route change setting request, it is simultaneously sent from the mobile communication device managed by the subscriber list 110 of the location registration server 11 and the viewing registration server 20. The route change setting is registered as standby switching information in association with the identification information (for example, telephone number) of the mobile communication device 3.
Then, the mobile communication device 3 is notified from the base station 12 that the route has been changed by putting it on the control signal (dashed line B in FIG. 2). When the mobile communication device 3 detects that the broadcast content can be viewed as described above, the mobile communication device 3 stops the standby operation performed with the mobile communication network 1.
By configuring as described above, notification of incoming calls and electronic mail distribution to the mobile communication device 3 are notified and distributed via the digital broadcasting network 2. For this reason, the operation of the communication control unit of the mobile communication device 3 only needs to stop the standby operation and execute the location registration process for periodically updating the neighboring base station information. It becomes possible to take longer than the state.
Further, since the mobile communication device 3 is linked to the digital broadcast network side, the location registration process for periodically updating the neighboring base station information may be stopped. However, in this case, when performing a response process to an incoming call notification described later, an operation for receiving a standby channel and establishing synchronization with the mobile communication network is required, as in the process at power-on. Processing takes time. However, since the power consumption of the mobile communication device can be significantly reduced by stopping the periodic location registration process in addition to the standby operation, it can be configured appropriately according to the situation. What is necessary is just to set it as the structure switched suitably.
Next, of the operations when there is an incoming call or electronic mail distribution when viewing digital broadcast content, the operation when there is an incoming call will be described. When there is an incoming call while viewing broadcast content, and a user who knows that call wishes to make a call in response to the call, it is necessary to shift to call processing.
In FIG. 1, when an incoming call notification means 101 of the mobile communication network 1 receives an incoming call notification addressed to the mobile communication device 3 in the mobile communication network, the location of the mobile communication device 3 is specified. In addition, the location registration server 11 is instructed to read location registration information via the delivery switching means 103.
In a normal state, the mobile communication device 3 outputs information about the base station 12 in which the mobile communication device 3 is located and performs an incoming call notification within the mobile communication network 1, but the mobile communication device 3 Since the standby control switching information indicates that the digital broadcast is being received, the location registration server 11 “the mobile communication device 3 is switching the standby control to the digital broadcasting network 1”. Information to that effect is returned to the incoming call notification means 101. The incoming call notification unit 101 switches the distribution route via the distribution switching unit 103, adds the identification information of the mobile communication device 3 to the incoming call notification conversion unit 201 of the digital broadcasting network 1, and receives the incoming call. An incoming call notification sending request is sent.
Note that the distribution switching unit 103 prepares for a response process to an incoming notification executed from the mobile communication device 3 to be described later via the mobile communication network 1 after distributing the incoming notification to the digital broadcasting network 1. Therefore, the communication path is switched back to the base station 12.
The incoming call notification conversion means 201 that has received the incoming call notification transmission request from the mobile communication network 1 specifies the user in the digital broadcast network from the identification information such as the telephone number of the mobile communication device 3 received together with the incoming call notification transmission request. The incoming notification data is converted into data for a digital broadcasting station and output to the data distribution device 22. At this time, the specified user information is also transferred to the data distribution device 22. (Note that if the incoming call notification conversion means 201 is included in the viewing registration server 20 in specifying the user, the user list 210 can be easily controlled with reference to it.)
The data distribution device 22 encrypts the incoming notification data based on the user specific information, and superimposes it on the broadcast content to the user currently distributed, and sends it out for a predetermined interval and period.
The mobile communication device 3 of the user who has received this incoming call notification obtains information on which the interruption point can be recognized, such as the time stamp of the broadcast content being viewed, and then changes the operation mode of the mobile communication device 3 to normal communication. Change to function. If the location registration processing is not stopped, the incoming call response processing is performed by accessing the base station 12 currently located. If the location registration processing has been stopped, the control processing received is the strongest after receiving the standby channel and establishing synchronization with the mobile communication network 1 in the same processing as when the power is turned on. Recognizing the base station 12 as a location, the location registration processing is performed, and the incoming call response processing is performed.
When receiving the incoming call response, the incoming call notification means 101 connects the incoming call to the mobile communication device 3 and shifts to a call. Also, the incoming call notification unit 101 notifies the incoming call notification conversion unit 201 of the digital broadcasting network 1 that there has been an incoming call response from the mobile communication device 3 via the distribution switching unit 103. The incoming notification conversion means 201 instructs the data distribution device 22 to stop the distribution of the incoming notification to the mobile communication device 3.
Note that the time stamp information of the broadcast content acquired when the mobile communication device 3 switches to the communication function is notified to the incoming call notification means 101 at the same time as the response signal in the incoming call response process. The incoming call notification unit 101 notifies the incoming call notification conversion unit 201 of the digital broadcast network 1 of the broadcast content time stamp information together with the incoming response completion data. In addition, the time stamp information of the broadcast content is held in the data distribution device 22 by notifying the data distribution device 22 of the information from the incoming notification conversion means 201 in the information instructing the stop of the incoming notification.
On the other hand, when the incoming call notification means 101 has not received the incoming call response from the mobile communication device 3 even after a predetermined time has elapsed after sending the incoming call notification transmission request to the incoming call notification conversion means 201 of the digital broadcasting network 1 In this case, the incoming call notification means 101 determines that the user is unable to respond, and sends an incoming call notification stop request to the incoming call notification conversion means 201 of the digital broadcasting network 1 to stop the incoming call notification from the digital broadcast station 1. For the caller, the absence processing represented by the answering machine service connection or the like is executed as necessary.
When the call end (disconnection or call end) is detected, the incoming call notification unit 101 notifies the incoming call notification conversion unit 201 of the digital broadcasting network 1 of the end of the call in the process of the disconnection process. Receiving notification of the end of the call, the incoming call notification conversion means 201 instructs the data distribution device 22 to resume digital broadcasting. At this time, since the information for identifying the user is added, the data distribution apparatus 22 resumes the distribution of the broadcast content based on the time stamp information of the broadcast content held when the stop of the incoming notification is instructed. .
As described above, when a call is received by the mobile communication device 3 that is viewing the digital broadcast content by stopping the standby operation via the mobile communication device 1, the digital communication network 2 is used. The incoming call notification process, the response process of the mobile communication device 3, the call and its end process, and the resumption of the digital broadcast viewing after the call end have been described.
Next, the e-mail delivery operation will be described.
In the case of e-mail distribution, a method of distributing to the mobile communication device 3 including the text of the e-mail, a notification that the e-mail has been distributed (including sender information and title), and the main text separately A method of obtaining an e-mail server according to the user's request is conceivable, but here it will be described as being distributed including the text.
When the mail delivery means 102 of the mobile communication network 1 receives the delivery of the e-mail addressed to the mobile communication device 3, the mail delivery means 102 specifies the position of the mobile communication device 3 in the same manner as the incoming call notification process described above. Then, the location registration server 11 is instructed to read location registration information via the delivery switching means 103.
In a normal state, information on the base station 12 in which the mobile communication device 3 is located is output and electronic mail distribution is performed within the mobile communication network 1, but the mobile communication device 3 Since the standby control switching information indicates that the digital broadcast is being received, the location registration server 11 is switching standby control to the mobile communication device 3 via the digital broadcasting network 1. Returns information to the effect. The incoming notification unit 101 switches the distribution route via the distribution switching unit 103, adds the identification information of the mobile communication device 3 to the distribution mail conversion unit 202 of the digital broadcasting network 1, and sends the electronic mail. To deliver.
The delivery switching means 103 receives an email reception completion notification executed via the mobile communication network 1 from the mobile communication device 3 to be described later after delivering the email to the digital broadcast network 1. Therefore, the communication path is switched back to the base station 12.
The distribution mail conversion means 202 that has received the electronic mail distribution from the mobile communication network 1 identifies the user in the digital broadcasting network from the identification information such as the telephone number of the mobile communication device 3 received together with the electronic mail distribution, and distributes it. The received e-mail is converted into data for a digital broadcasting station and output to the data distribution device 22. At this time, the specified user information is also transferred to the data distribution device 22. (It should be noted that if the distribution mail conversion means 202 is included in the viewing registration server 20 in specifying the user, the user list 210 can be easily controlled with reference to it.)
The data distribution device 22 encrypts the e-mail data based on the user's specific information, and superimposes it on the broadcast content to the user currently distributed, and sends it out for a predetermined interval and period.
If the e-mail size is large and the distribution is not completed once, it is divided and distributed as necessary.
The mobile communication device 3 separates the e-mail data from the broadcast content data distributed from the data distribution device 22, and receives and stores it in the own device. In the case of divided distribution, it is appropriately recombined and stored in the own device.
When reception of all e-mail data is completed, the mobile communication device 3 performs e-mail reception completion processing on the mobile communication network 1 in the background of viewing digital broadcast content. In the mobile communication device 3, a reception mark indicating that the electronic mail has been delivered is displayed on the display unit to notify the user. At this time, the electronic mail subject, the mail sender, and a part or all of the mail text may be displayed on the display unit according to user settings. In addition, as a display method, the broadcast content being viewed may overlap and be displayed, or may be displayed separately from the broadcast content on a part of the display unit.
This e-mail reception completion process is performed by performing a pseudo location registration operation in the same manner as the response process for the incoming call notification.
Therefore, if the position registration process is not stopped even if the standby operation is stopped, the base station 12 currently in the area is accessed and information indicating that the reception of the e-mail is completed is sent. If the location registration processing has been stopped, the control processing received is the strongest after receiving the standby channel and establishing synchronization with the mobile communication network 1 in the same processing as when the power is turned on. Recognizing the base station 12 as a location location, location registration processing is performed, and e-mail reception completion information is sent.
The mail delivery means 102 that has received the notification of completion of the e-mail reception from the mobile communication device 3 may send a signal to that effect to the digital broadcasting network 2 as necessary.
If the mail distribution means 102 cannot receive the e-mail reception completion information addressed to the mobile communication device 3 distributed via the digital broadcasting network 2 even after a certain period of time, the mobile communication device 3 cannot receive the e-mail. The electronic mail delivered to the mobile communication device is stored in a mail server (not shown). In addition, the digital broadcast network 2 may be notified of the fact that there has been no e-mail reception completion notification from the mobile communication device 3 and that the process of storing the delivered e-mail in a mail server (not shown) has been performed. Good.
As described above, the standby operation via the mobile communication device 1 is stopped, and the electronic mail is delivered to the mobile communication device 3 viewing the digital broadcast content, via the digital broadcast network 2. The distribution process has been described.

The location information of the body communication device 3 and the user list 210 of the viewing registration server 20 and information related to the mobile communication device 3 registered to view the digital broadcast are managed. FIG. 7A shows an example of data registered in the user list 210, and FIG. 7B shows an example of data registered in the subscriber list. The contents and meaning of each registered data will be described in the following explanation process.
FIG. 8 is a sequence diagram for explaining the operation when digital broadcast viewing registration is performed by the user of mobile communication device 3.
The user of the mobile communication device 3 who wishes to view the digital broadcast accesses the viewing registration server 20 of the operator operating the digital broadcast using the mobile communication device (801 in FIG. 8). At this time, the mobile communication device 3 may access the viewing registration server 20 via a telephone line from the mobile communication network 1 via the base station 12, or may access from the Internet. For example, if a viewing registration website is accessed via the Internet, a viewing registration menu is sent to the mobile communication device 3 (802 in FIG. 8).
According to the menu, the user can make a reservation for viewing by inputting and transmitting information necessary for viewing to the Web (803 in FIG. 8). As information necessary for viewing, information for identifying broadcast content to be viewed, time for viewing, and information for identifying and identifying a user are at least required.
The viewing registration server 20 creates and edits viewing-related information necessary for user viewing management based on this viewing registration, and sets it in the user list 210 shown in FIG. The viewing related information is roughly divided into a user information area for specifying a user and a service information area related to a service provided to each user.
As user information, viewing control including a name indicating the name of the user, identification information for identifying the user such as a telephone number of the mobile communication device 3, and decryption key information that enables reception only by the user. Register the information and the management number assigned by the digital broadcaster as necessary.

The viewing registration server 20 that has registered the above information in the user list 210 returns a reservation completion notification to the mobile communication device 3 (804 in FIG. 8). At this time, decryption key information for permitting the user to view broadcast content separately distributed is transmitted to the user's mobile communication device 3.
Next, a preparation process for performing digital broadcast viewing and standby processing by the user of the mobile communication device 3 via the digital broadcast network will be described.
FIG. 9 is a sequence diagram for explaining the operations from the start of digital broadcast viewing by the user of the mobile communication device 3 to the preparation processing for performing the standby processing of the mobile communication device 3 via the digital broadcast network.
When the viewing start time registered and set by the user of the mobile communication device 3 is reached, the viewing registration server 20 refers to the user list 210 and starts distribution control of the broadcast content to the corresponding user.
First, the viewing registration server 20 notifies the content server 21 of the content codes registered in the user list 210 and instructs the output of the broadcast content corresponding to the content code. On the other hand, the data distribution device 22 is notified of the content code and viewing control information that designates an encryption process that enables viewing only to a specific user who has registered viewing of the broadcast content. The data distribution device 22 encrypts the broadcast content data output from the content server 21 according to the viewing control information notified from the viewing registration server 20, sends it to the digital broadcast station 23 as digital broadcast data, and places it on the broadcast radio wave to the user. To deliver. At this time, processing for changing the delivery notification route of the mobile communication device 3 and the delivery route of the electronic mail via the digital broadcast network 2 is executed, so the data delivery device 22 first transmits from the digital broadcast station 23. As digital broadcast data, not actual broadcast content but training data for route change setting processing is distributed (901 in FIG. 9).
The mobile communication device 3 that has received broadcast radio waves from the digital broadcast station 23 and is able to view using the decryption key information acquired at the time of viewing registration and has detected the training data is provided in the mobile communication network. 1 is requested to change the standby processing path.
The mobile communication device 3 performs a pseudo location registration process via the base station in which it is located (902 in FIG. 9). This pseudo location registration process uses the same procedure as the normal location registration process. However, the standby switching information indicating that “the digital broadcast reception is started and the standby operation is performed via the digital broadcast network 2” is used as the location registration information. Instead, it is sent to the control device 10 via the base station. Alternatively, the standby registration information may be added to the location registration information for transmission.
The control device 10 that has received this standby switching information instructs the location registration server 11 to register it in the subscriber list 110 in association with the location information of the mobile communication device 3 (903 in FIG. 9).
An example of the subscriber list 110 is shown in FIG. In the subscriber list 110, a subscriber number is a telephone number assigned to the mobile communication device 3, terminal identification information is unique identification information such as a machine number of the mobile communication device 3, and location information is the mobile communication device.

In addition to these, the data separation unit 35 that decodes various data distributed in a digital broadcast and separates it into broadcast data and other additional data, other than the broadcast data separated by the data separation unit 35 A viewing information control unit 36 that executes processing based on the additional data and a standby switching control unit 37 that executes control processing related to standby switching according to the present invention. Note that radio waves for digital broadcasting are received via the antenna 38, and radio waves for mobile communication are transmitted and received by the antenna 39.
When the mobile communication device 3 configured as described above receives the above training data from the digital broadcast station 23, the mobile communication device 3 is separated by the data separation unit 35 and transferred to the viewing information control unit 36. When the viewing information control unit 36 identifies the training data, the viewing information control unit 36 instructs the standby switching control unit 37 to execute processing for requesting the standby processing path change setting by pseudo-position registration. In response to this, the standby switching control unit 37 instructs the communication processing unit 32 to execute the pseudo location registration process. In addition, as described above, when preparation for standby switching in the mobile communication network 1 and the digital broadcasting network 2 is completed and the stop of training data is detected, the viewing information control unit 36 notifies the standby switching control unit 37 to that effect. To stop the standby operation. The standby switching control unit 37 that has received the instruction to stop the standby operation instructs the communication processing unit 32 to stop the standby operation. In this way, processing within the mobile communication device 3 is performed, and the standby operation is stopped.
Next, of the operations when there is an incoming call or electronic mail distribution when viewing digital broadcast content, the operation when there is an incoming call will be described. When there is an incoming call while viewing broadcast content, and a user who knows that call wishes to make a call in response to the call, it is necessary to shift to call processing.
FIG. 10 is a sequence diagram for explaining the operation when a call is received when viewing digital broadcast content.
When the control device 10 of the mobile communication network 1 receives an incoming call notification addressed to the mobile communication device 3 in the mobile communication network from the communication processing unit 120, the control device 10 specifies the position of the mobile communication device 3. Next, the location registration server 11 is instructed to read the location registration information (1001 in FIG. 10).
In the normal state, the location registration server 11 outputs the information of the base station where the mobile communication device 3 is located and performs an incoming call notification within the mobile communication network 1. Since it is registered in the standby control information of the subscriber list that the communication device 3 is receiving the digital broadcast, the location registration server 11 performs the standby control of the mobile communication device 3 via the digital broadcast network 1. Is returned to the control device 10 (1002 in FIG. 10).
The control device 10 that has known that the standby control is being switched sends an incoming notification notification request for adding the identification information of the mobile communication device 3 and notifying the incoming of the call via the distribution switching processing unit 130. It is sent to the viewing registration server 20 of the digital broadcasting network 1 (1003 in FIG. 10).
The viewing registration server 20 that has received the incoming notification transmission request from the mobile communication network 1 searches the user list 210 based on the identification information such as the telephone number of the mobile communication device 3 received together with the incoming notification transmission request, and digitally A user in the broadcast network is specified, and the incoming notification data is converted into data for the digital broadcasting station via the information distribution processing unit 240 and output to the data distribution device 22. At this time, the specified user information is also transferred to the data distribution device 22. The data distribution device 22 encrypts the incoming notification data based on the user's specific information, and superimposes it on the broadcast content to the currently distributed user and sends it out for a predetermined interval and period (1004 in FIG. 10). ).
When the mobile communication device 3 of the user receives the incoming notification separately from the broadcast data by the data separation unit 35 in FIG. 6, the viewing information control unit 36 executes an incoming notification reception process.
First, an incoming notification is notified to the user. As an optimal method, an incoming call display message or mark may be blinked on the display unit 33 so that a signal sound or the like may be sent simultaneously.
The user who has recognized the incoming call display presses a response button on the operation unit 34 in order to respond to the incoming call. The pressing of the response button is notified to the viewing information control unit 36, and the viewing information control unit 36 stops the incoming call display and instructs the standby switching control unit 37 to execute the response process. At this time, it is also possible to obtain information capable of recognizing the interruption point such as a time stamp of the broadcast content being viewed and add the interruption point information to instruct.
When the standby switching control unit 37 instructs the communication processing unit 32 to execute the response process, the communication processing unit 32 accesses the base station currently located and performs the incoming call response process (1005 in FIG. 10). ). Also at this time, a response signal and interruption point information are transferred to the control device 10 as a pseudo location registration process.
The control device 10 that has recognized the signal received via the base station as a response signal from the mobile communication device 3 that has sent the incoming notification via the digital broadcasting network causes the communication processing unit 120 to send the incoming call to the mobile communication device 3. Connecting. On the other hand, a notification that a response has been received (response completion notification) is sent to the viewing registration server 20 of the digital broadcasting network 2 (1006 in FIG. 10). At this time, if there is interruption point information such as a time stamp, it is also notified at the same time.
Based on the response completion notification received from the control device 10 of the mobile communication network 1, the viewing registration server 20 enters the service status information column of the user data of the user of the mobile communication device 3 registered in the user list 210. The data indicating that the call is in progress and the time stamp information of the interruption point are registered, and then the data distribution device 22 is instructed to stop the transmission of the incoming notification data.
When the mobile communication device 3 detects the end of the call (disconnection or call end), the control device 10 causes the communication processing unit 120 to execute the disconnection process and notifies the viewing registration server 20 of the digital broadcast network 1 of the end of the call. (1007 in FIG. 10). The viewing registration server 20 that has received the notification of the call termination refers to the user list 210 and determines the next process for the user. The data indicating that the call is in progress, which is registered in the service status information field of the user's user data, is rewritten to resume delivery, and the time stamp information of the interruption point is notified to the data delivery device 22 via the information delivery processing unit 240 And instruct to resume digital broadcasting. The data distribution device 22 resumes the distribution of the broadcast content based on the notified user information and time stamp information (1008 in FIG. 10).
