[0028]
In addition, as shown in FIG. 1, the base station device 70 has predetermined cells 1, 2, 3, 4, 4 to which identification information (identification numbers “1” to “5” in FIG. 1) is assigned. It is installed every 5, ...
[0029]
This information communication system is capable of broadcasting (broadcasting) an unspecified mobile phone terminal device 80 as in the text information broadcasting system disclosed in, for example, Japanese Patent Laid-Open No. 2001-197021.
[0030]
Therefore, the base station device 70 includes a communication control unit 71 that performs communication control such as calling and channel setting for the mobile phone terminal device 80 in the cell in which the base station device 70 is installed, and an unspecified in the cell. A CBS (Cell Broadcast Service) unit 72 that broadcasts to the mobile phone terminal device 80 and a transmission / reception unit 73 that transmits and receives high-frequency signals to the mobile phone terminal device 80 are provided. Further, the CBS unit 72 includes a position information holding unit 72a that holds identification information assigned to a cell in which the base station device 70 is installed.
[0031]
In addition, although the example which provided the CBS part 72 in the base station apparatus 70 was demonstrated in this FIG. 1, this CBS part 72 can also be comprised as an apparatus different from the base station apparatus 70. FIG. In addition, FIG. 1 illustrates a case where the base station apparatus 70 corresponds to a cell on a one-to-one basis (that is, the CBS unit 72 corresponds to a cell on a one-to-one basis). The cells can be divided into microcells at predetermined angles (for example, 120 °) from the center of the cells by switching the sex. In this case, a plurality of microcells correspond to one base station apparatus 70, but one CBS unit 72 is provided for each base station apparatus 70, and each microcell corresponding to this base station apparatus 70 is provided. One CBS unit 72 may transmit the same position information.

In this case, each cell can be identified so that each cell can be identified. The position information transmitted by the CBS unit 72 is preferably unique information.
[0032]
On the other hand, the mobile phone terminal device 80 transmits data between the communication control unit 81 that performs communication control with the base station device 70, the call processing unit 82 that performs voice call processing, and the communication control unit 81. Information indicating a cell in which the packet transmitting / receiving unit 83 that transmits and receives communication packets, a CBS receiving unit 84 that receives information from the CBS unit 72, and the mobile phone terminal device 80 that is supplied from the CBS receiving unit 84 exists. A position information holding unit 85 for holding (position information), a Web browser 86 using an HTTP service provided by the HTTP server 11, an operation key 87 for inputting a telephone number, an operation instruction, and the like, and a liquid crystal display (LCD) And a display control unit 89 that controls the display unit 88.
[0033]
(Overview of operation)
Between the base station device 70 and the mobile phone terminal device 80, for example, as shown in FIG. 2A, communication of a plurality of channels is performed by time division multiplex communication using a signal of a predetermined frequency in time division. It is like that.
[0034]
As shown in FIG. 2A, as a physical channel, for example, a control channel (CCH: Control Channel) that can be used for communication control such as call setting and a packet bearer service such as an HTTP service can be used. A packet channel (UPCH: User Packet Channel) is provided. More detailed formats and the like of these channels are stipulated in “Digital Car Telephone System Standard RCR STD-27J Version”.
[0035]
Furthermore, in this information communication system, a broadcast physical channel (BPCH) that can be used for broadcasting to an unspecified mobile phone terminal device 80 is provided as in the above-described text information broadcast system. For example, as shown in FIG. 5B, a super frame is formed by data for 36 time slots of the broadcast physical channel (BPCH), and CBS is formed by 70 super frames, for example, as shown in FIG. A hyperframe is configured.
[0036]
This CBS hyperframe includes 64 channels from ch0 to ch63, each of ch0 and ch1 is included, and each of the remaining channels from ch2 to ch63 is included. That is, the CBS hyperframe is composed of a total of 70 channels, and each channel corresponds to one superframe. The location information for each base station device 70 described above is transmitted by ch0.
[0037]
The location information holding unit 72a of the CBS unit 72 holds unique location information for each cell (or each CBS unit 72) as location information, and this location information is stored in the above-described CBS hyperframe ch0. Is sending through.
[0038]
This location information may be, for example, information such as an identification number unique to each CBS unit 72. For example, the latitude and longitude and / or the address where the base station device 70 corresponding to the CBS unit 72 is installed may be used. By using the character information shown, it can be used as it is when being displayed on the display unit 88 in the cellular phone terminal device 80.
[0039]
Specifically, the latitude and longitude can be represented by character information such as “xxxxxxxx (0x1A) yyyyyy”. Here, xxxxxxxx is a maximum 7-digit latitude, yyyyyyyy is a numeric character code indicating the maximum 7-digit longitude, and (0x1A) is a character code indicating these delimiters. The address can be expressed by character information such as “Minato-ku Atago xyz”. In the following description, a case will be described in which both character information indicating latitude and longitude and character information indicating an address are used as position information.
[0040]
In other channels, for example, information (area information) such as transportation, facilities, restaurants, and events corresponding to the cell corresponding to the position information holding unit 72a is transmitted for each category.
[0041]
The communication control unit 81 of the mobile phone terminal device 80 receives the broadcast physical channel (BPCH) and supplies it to the CBS reception unit 84 when it is set to receive CBS. For example, the CBS receiving unit 84 extracts and holds data of a channel set to be received in advance, extracts the above-described position information from the ch0 data, and supplies the extracted position information to the position information holding unit 85. As described above, the location information differs for each CBS unit 72, and the CBS unit 72 and the cell correspond to each other. Therefore, the location information holding unit 85 includes location information corresponding to the location of the mobile phone terminal device 80. Is held.
[0042]
In the cellular phone terminal device 80, for example, an HTTP service provided by the HTTP server 11 can be used by a packet transmitted through a packet channel (UPCH).
[0043]
Services provided by the HTTP server 11 include services according to location information such as maps, transportation facilities, facilities, or route guidance. When using a service according to such position information, the position information held in the position information holding unit 85 of the mobile phone terminal device 80 is supplied to the HTTP server 11, and the position to which the HTTP server 11 is supplied is supplied. Information corresponding to the information (for example, a map image, the location of the nearest station, a list of public facilities, etc.) is transmitted to the Web browser 86 of the mobile phone terminal device 80. Information corresponding to the position information is stored in the data holding unit 12 in advance in association with the position information, for example, and the HTTP server 11 reads out from the data holding unit 12 based on the position information supplied from the Web browser 86. It transmits to the Web browser 86.
[0044]
The Web browser 86 can display the information supplied from the HTTP server 11 in accordance with the position information in this way on the display screen of the display unit 88 and use the information displayed by the user.
[0045]
By the way, the cellular phone terminal device 80 can appropriately change the operation mode such as the availability of CBS reception, the reception frequency, the channel to be received, etc. according to the setting of the user in order to save power. ing. For this reason, the communication control unit 81 includes a memory that holds information indicating these operation modes, and a reception control unit that controls reception of CBS according to the information held in the memory.
[0046]
For example, when the operation mode for receiving CBS is set, the communication control unit 81 receives the CBS of the channel set at a preset time interval at the time of waiting for an incoming call, etc., and receives the received data. This is supplied to the CBS receiver 84. The CBS receiving unit 84 holds the data of each channel from the supplied CBS data, and supplies the position information holding unit 85 with the position information of ch0 described above. Thereby, the position information held in the position information holding unit 85 is updated at a predetermined time interval (reception frequency). On the other hand, when the operation mode in which CBS is not received is set or when CBS cannot be received during a call or the like, the communication control unit 81 does not receive CBS and holds it in the position information holding unit 85. The position information that has been set is not updated.
[0047]
Since the operation mode can be switched as described above, the CBS receiving unit 84 of the mobile phone terminal device 80 does not always receive the CBS, and the position information of the position information holding unit 85 is not updated. A case where the mobile phone terminal 80 moves to another cell can be considered.
[0048]
Also, for example, when moving to another cell while using a service via a channel that can be used exclusively with BPCH (ie, a channel that cannot be received simultaneously with BPCH), such as a call service or an HTTP service using UPCH, There may be a case where the position information held in the position information holding unit 85 does not correspond to the current position of the mobile phone terminal device 80.
[0049]
Therefore, in this mobile phone terminal device 80, when using the position information held in the position information holding unit 85 (for example, transmission of the position information, selection of processing according to the position information, etc.) Whether or not to update the information is confirmed, and when updating of the position information is instructed, the position information holding unit 85 receives the position information provided via the BPCH by temporarily disconnecting the packet session by UPCH and receiving the position information. The position information held in is updated.
[0050]
When providing a service that uses position information, HTML (Hyper Text Markup Language) in which an instruction (transmission instruction) for transmitting position information held in the position information holding unit 85 is defined from the HTTP server 11 to the Web browser 86 is defined. Alternatively, display data described in a script language such as MML (Mobile Markup Language) is supplied.
[0051]
In the case of HTML, the transmission instruction is defined as an option (for example, z attribute) of a predetermined tag such as <a> or <from>. In the case of MML, it is defined as an option (for example, Z attribute) of a predetermined tag such as <A> or <F>. In response to such a transmission instruction, the Web browser 86 of the mobile phone terminal device 80 transmits, for example, information to the HTTP server 11 as information in the HTTP request header.
[0052]
Display data including such a position information transmission command is supplied to the web browser 86 during service use (during web browsing) by the HTTP server 11 in a packet session using UPCH, for example, as shown in FIG. .
[0053]
Prior to the transmission of the position information corresponding to the command in the display data, the Web browser 86 confirms whether or not to update the position information to the user. When the user selects to update the position information, the web browser 86 instructs the communication control unit 81 to disconnect the packet session, and instructs the communication control unit 81 to receive the position information supplied via the BPCH.
[0054]
In response to this, when the CBS reception data is supplied from the communication control unit 81, the CBS reception unit 84 starts updating the position information, and extracts the position information in the above-described ch0 data. The information is supplied to and held in the information holding unit 85. When the update of the position information is completed, the communication control unit 81 enters a standby state and enters a CCH reception state.
[0055]
In this state, when the user selects transmission of updated location information, a new packet session is connected between the Web browser 86 and the HTTP server 11, and the HTTP server 11 responds to the location information supplied from the Web browser 86. Information such as a map image is transmitted to the Web browser 86. The web browser 86 causes the display unit 88 to display an image such as a map and characters according to the received information. Thereby, the user can use information according to the position information.
[0056]
(Detailed operation)
In order to confirm whether or not the position information held in the position information holding unit 85 is updated by the user, for example, an operation for confirming the update of the position information for the user in display data supplied to the Web browser 86 is defined. Keep it.
[0057]
In the service of providing a map near the current position of the cellular phone terminal device 80, for example, before transmitting the position information held in the position information holding unit 85 and requesting map image data or the like in S106 in FIG. Then, the image 101 that allows the user to input an instruction to confirm the position information is displayed, and the position information is updated according to the user instruction.
[0058]
When the user selects to provide a map from the selection menu for providing the map, the Web browser 86 transmits the address (URL, etc.) of the display data of the update confirmation screen defined in the display data of the selected menu to the HTTP server 11. Then, display data of the update confirmation screen is requested (S101).
[0059]
In response to this, the HTTP server 11 supplies display data of the update confirmation screen to the Web browser 86 (S102). The web browser 86 displays the image 101 of the update confirmation screen on the display unit 88 according to the supplied display data, and waits for an instruction input from the user. The image 101 includes a current position display 101a, a display 101b asking whether or not to update the current position, and displays 101c and 101d indicating selectable instructions. When the user operates the operation key 87 to instruct “update” corresponding to the display 101c, the Web browser 86 instructs the communication control unit 81 to disconnect the packet session (S103), via the BPCH. Instructs reception of position information being transmitted.
[0060]
In response to this, when CBS reception data is supplied from the communication control unit 81, the CBS reception unit 84 starts updating the position information and supplies the position information in ch0 to the position information holding unit 85 (S104). ).
[0061]
When the update of the position information is completed, the Web browser 86 displays an image 102 of a transmission confirmation screen for confirming whether or not to transmit the position information to the user. The image 102 includes a current position display 102a, a display 102b asking whether or not to transmit position information of the current position, and displays 102c and 102d indicating selectable instructions. On the other hand, when the user instructs “transmission” corresponding to the display 102c, the web browser 86, for example, in accordance with the tag of the above-described position information transmission instruction associated with the “transmission” display, The communication control unit 81 is instructed to connect a packet session with the HTTP server 11 (S105), and the position information held in the position information holding unit 85 is transmitted to the HTTP server 11 (S106).
[0062]
This position information is transmitted to the HTTP server 11 as information in the HTTP request header, for example. The HTTP request header for transmitting the location information can be defined as shown in FIG. 5, for example. When such an HTTP request header is received, the HTTP server 11 analyzes this header and, for example, sets “xxxxxxxx (0x1A) yyyyyy (0x1A) Minato-ku Ehime xyz as the value of the variable“ xj-phone-goocode ”. Set the string "". The value of the variable set in this way is referred to when the HTTP server 11 acquires provided information (for example, a map image corresponding to the position information) from the data holding unit 12 according to the position information.
[0063]
Alternatively, the Web browser 86 transmits data in the HTTP request header in an abbreviated format (for example, variable names “xj-phone-goocode”, “geocode”, etc. are displayed with abbreviated names) to the gateway device 30. In response to this, the gateway device 30 may construct an HTTP request header having the format shown in FIG. 5 and transmit it to the HTTP server 11. As a result, the amount of data to be transferred from the Web browser 86 to the gateway device 30 can be reduced. In general, since the communication rate in the wireless section (between the mobile phone terminal device 80 and the base station device 70 or the packet switch 60) is lower than the communication rate between the gateway device 30 and the HTTP server 11, the position information transmitted by the Web browser 86 is used. By adopting the abbreviated format, it is possible to reduce the traffic in the wireless section.
[0064]
When the position information from the web browser 86 is received, the HTTP server 11 transmits data such as a map image (for example, a map image near the position information) according to the received position information to the web browser 86. When the data from the HTTP server 11 is received, the Web browser 86 displays an image corresponding to the received data, for example, the map image 103.
[0065]
When the user instructs “continue” corresponding to the display 101d to the image 101 on the update confirmation screen, the Web browser 86 disconnects the packet session and receives position information in S103 to S104. The image 102 of the transmission confirmation screen is displayed without performing the above. In this state, since the packet session remains connected, the Web browser 86 can execute the connection of the packet session in S105 when the user instructs “transmission” corresponding to the display 102c to the image 102. Instead, the position information held in the position information holding unit 85 is transmitted to the HTTP server 11 (S106).
[0066]
(effect)
As described above, in the information communication system according to this embodiment, even when a service using a packet channel (UPCH) such as an HTTP service is used, BPCH which is a time slot exclusive to UPCH is used. The position information transmitted via the position information can be received and the position information held in the position information holding unit 85 can be updated. For this reason, it can contribute to the improvement of the accuracy of the service according to position information.
[0067]
Further, in the information communication system according to this embodiment, the user confirms with the user before updating the position information. Therefore, when the current position information is correct, the service is provided using the position information on the site. Can do. For this reason, it is possible to prevent the traffic from being increased unnecessarily and the response to the user from taking time.
[0068]
(Modification 1)
In the above description, the case where time division multiplexing communication is used for communication between the base station device 70 and the mobile phone terminal device 80 and the CBS hyperframe having the full rate configuration shown in FIG. 2 is used is described. The configuration itself of the data to be transmitted is not limited. For example, the present invention can also be applied to a case where a half-rate CBS hyperframe disclosed in Japanese Patent Application Laid-Open No. 2001-97021 is used. it can.
[0069]
The present invention can also be applied to an information communication system in which, for example, a channel that provides services by an HTTP server and a channel that provides location information have different frequencies. In this case as well, as described above, when the location information needs to be updated when using the service provided by the HTTP server, the connection of the channel used for using the service (packet session) ) And the location information is updated through the channel providing the location information, and then the packet session with the HTTP server is reconnected.
[0070]
Further, in the above description, in the display data of the service supplied via the packet session, the case where the display of the screen for confirming whether or not to update the location information is defined for the user is described. Then, only the position information transmission command is defined, and the Web browser 86 updates the position information to the user when executing the position information transmission command (for example, the command for transmitting the position information as an environment variable or the like). You may make it confirm whether or not.
[0071]
In the display data provided by the HTTP server 11, when the display of a screen for confirming whether or not to update the position information is defined for the user, the display data is complicated and the size is increased, and transmission is performed. Time can increase and can contribute to increased traffic.
[0072]
On the other hand, if only the position information transmission command is defined in the display data, and the Web browser 86 confirms the update of the position information to the user at the time of execution of the command, the display information is displayed. Data complexity and size increase can be suppressed, which can contribute to traffic control.
[0073]
Even in the information communication system according to each of the above-described modifications, by applying the present invention, the location information held in the mobile phone terminal device is updated even when a service using a packet channel is used. can do. For this reason, it can contribute to the improvement of the accuracy of the service according to position information.
[0074]
(Modification 2)
In the above description, an example of selecting whether or not to perform CBS reception according to the setting of the operation mode has been described, but the position information update control procedure may further vary.
[0075]
For this purpose, for example, the mobile phone terminal device 80 is provided with a schedule management unit 801 for managing a schedule for updating position information, and a mode information holding unit 802 for holding mode information indicating an operation mode such as an update schedule.
[0076]
As the operation mode, for example, “auto”, “semi-auto”, “manual” and the like are provided. In the “auto” mode, the position information is automatically updated at every update interval (for example, 6 hours or 12 hours). In this case, the position information may not be periodically updated unless an update interval is set. In addition, instead of setting an update interval, for example, the location information is updated every time the cell moves, or the location information is updated at the update time of the CBS channel to be received (update condition) Condition) may be set.
[0077]
In the “semi-auto” mode, for example, the position information is manually updated only at the beginning of the day, and thereafter, the operation is the same as in the “auto” mode. Further, in the “manual” mode, when there is a need for transmission of position information or the like, confirmation is sequentially made with the user.
[0078]
For example, an identification code is associated with each operation mode, update interval, and update condition. When the user designates an operation mode or the like via the Web browser 86 or the like, the schedule management unit 801 displays these codes. The identification code corresponding to the operation mode is stored in the mode information holding unit 802. The schedule management unit 801 controls the operation and the like of the communication control unit 81 according to the identification code stored in the mode information holding unit 802 to update the position information.
[0079]
In this way, if a plurality of operation modes, update intervals, update conditions, and the like can be set, the user can set the operation mode as appropriate according to his / her action schedule, etc., thereby extending the update interval and saving. It is possible to increase the power and to shorten the update interval to improve the followability of the position information and to receive a service with good responsiveness according to the movement. Thereby, it can contribute to the improvement of a user's convenience.
[0080]
(Modification 3)
Further, in the above description, when updating the position information, as illustrated in FIG. 4, an example in which the packet session is temporarily disconnected and the BPCH is received and then reconnected is described. There is room for improvement in order to improve traffic and reduce traffic.
[0081]
When connecting a packet session, communication parameter setting, authentication, etc. according to PPP (Point to Point Protocol) between the mobile phone terminal device 80 and the network side device such as the base station 70 and the packet switch 60 The packet session is established by setting the information (session information) related to the packet session. Therefore, for example, when the session is reconnected in S105 in FIG. 4, it is necessary to perform the same processing, and there is room for improvement from the viewpoint of reducing traffic and improving responsiveness.
[0082]
For this reason, for example, storage means such as a register 61 a that holds session information (MS context) relating to a packet session such as a packet channel (UPCH) assigned to communication with the Web browser 86 in the exchange control unit 61 of the packet switch 60. In response to a request sent when the Web browser 86 updates the location information, the session information is held in the register 61a and the packet session is temporarily disconnected (narrow interruption in the narrow sense), and held in the register after a predetermined time. The suspended session may be reestablished based on the session information.
[0083]
In the case of such a configuration, for example, as shown in FIG. 6, the Web browser 86 of the mobile phone terminal device 80 transmits a packet communication request (S201), communication parameter setting, authentication, etc. with the packet switch 60, etc. The process is executed (S202). When the processing such as authentication is normally completed, the packet switch 60, for example, stores information related to the packet session such as the packet channel (UPCH) allocated to the mobile phone terminal device 80 in the storage means such as the register 61a in the switch control unit 61. Is stored in the session information (MS context) that includes (S203).
[0084]
When the session is established in this way, packet communication is performed between the Web browser 86 of the mobile phone terminal device 80 and the HTTP server 11 (S204). Thereafter, when updating the position information, if the Web browser 86 transmits a packet communication interruption request to the packet switch 60 (S205), the packet switch 60 that has received the request does not clear the MS context held in the register 61a. Then, the session is disconnected (S206). At this time, the packet switch 60 starts counting the session resumption timer 61b. The set time of this timer is set in consideration of the interval of position information transmitted by CBS.
[0085]
On the other hand, the web browser 86 of the mobile phone terminal 80 transmits a packet communication interruption request, and then instructs the communication control unit 81 to receive BPCH. The CBS receiving unit 84 extracts position information from the BPCH received data from the communication control unit 81 and holds the position information in the position information holding unit 85. Thereby, the position information is updated (S207).
[0086]
When the set time of the above-described session resumption timer ends, the packet switch 60 re-establishes the session based on the MS context held in the register 61a (S208). At this time, unlike the first connection, authentication processing is not performed. When the session is re-established, packet communication between the Web browser 86 and the HTTP server 11 is resumed (S209), and for example, a service corresponding to the location information transmitted from the Web browser 86 is provided.
[0087]
As described above, when updating the location information, the packet session is not disconnected, but is suspended in a state where the session information (MS context) is held, and after receiving the location information, the packet session is re-established. For example, authentication processing necessary for resetting a packet session is not necessary, which can contribute to traffic reduction and responsiveness improvement.
[0088]
