Method and system for realizing personalized ring back tone

Technical field

The present invention relates to mobile communication technologies, and more particularly to a method and system for implementing personalized ring back tones. Background technique

With the advancement of society and the development of the economy, the personalized ring back tone (CRBT) business has become more and more popular, and has become a manifestation of the younger generation chasing fashion and personality. Personalized ringback tones make people not only hear monotonous and boring "beep...beep" sounds every time they make a call, but instead they have a variety of distinctive sounds.

The existing personalized ring back tone service is mainly for the called user, that is, when the user subscribes to the personalized ring back tone service, when the called party receives the call from the calling user, the called party plays the signed personality. The ringback tone is replaced by the original "beep...beep..." ringback tone. In the implementation manner of the existing personalized ring back tone service, the user subscribes to the personalized ring back tone service in the home location register (HLR); the HLR encrypts the personalized ring back tone information subscribed by the user, such as personalized ring back tone subscription activation. The logo and the personalized ring back tone server address are carried in the location registration class process and sent to the mobile switching center (MSC); when the user accepts the call as the called party, the MSC establishes personalized according to the personalized ring back tone subscribed by the called user. Ringback tone branch. The MSC may be the calling MSC or the called MSC. The two personalized ringback tone implementation modes are respectively called the landing party personalized ring back tone service and the gateway office personalized ring back tone service. FIG. 1 is a flow chart of realizing the personalized ring back tone service of the existing landing office. As shown in Figure 1, the following steps are included:

Step Lll ~ L12: Normal call, the calling MSC sends a location request message to the HLR.

Step L13: After receiving the location request message, the HLR sends a route request message to the called MSC to request a routing number.

Step L14: After receiving the route request message, the called MSC allocates a route number to the called user, and sends the assigned route number to the HLR through the route request response message.

Step L15: The HLR sends a location request response message to the calling MSC.

Step L16: The calling MSC sends an outgoing message to the called MSC to connect the called party. Step LI 7: The called MSC sends a response message to the calling MSC.

Step L18: The called MSC determines that the called user has subscribed to the personalized ring back tone service, sends a message to the personalized ring back tone platform, establishes a personalized ring back tone branch of the called party, and plays a personalized ring back tone for the calling user. sound.

Figure 2 is a flow chart of the implementation of the personalized ringback tone service for the current mouth office. As shown in Figure 2, the following steps are included:

Steps L21 ~ L22: Normal call, the calling MSC sends a location request message to the HLR.

Step L23: The HLR receives the location request message, and sends a route request message to the called MSC to request the routing number.

Step L24: After receiving the route request message, the called MSC allocates a route number to the called user, and sends the assigned route number to the HLR through the route request response message.

Step L25: The HLR sends a location request response message to the calling MSC, with a loop number, and carries the personalized ring back tone information signed by the called user.

Step L26: The calling MSC sends an outgoing message to the called MSC to connect the called party.

Step L27: The called MSC sends a response message to the calling MSC.

Step L28: The calling MSC determines that the called user has subscribed to the personalized ring back tone service, sends a message to the personalized ring back tone platform, establishes a personalized ring back tone branch of the called party, and plays a personalized ring back tone for the calling user. sound.

In the existing personalized ring back tone implementation, for the calling user, no matter what kind of personalized ring back tone is played by the called user, it can only be answered; and the called user cannot enjoy it. Personalized ring back tone that is signed by itself. Therefore, the calling party personalized ring back tone service is proposed in the prior art. If the user signs the caller's personalized ring back tone, when the call is initiated as the calling user, the caller can personally hear the ringing tone of the caller and enjoy the personalized ringback tone of the calling party. In the implementation manner of the existing caller personalized ring back tone service, the user signs the caller personalized ring back tone service in the home HLR, and sends the personalized ring back tone information to the MSC, where the information is saved by the MSC. The subscribed caller personalized ring back tone service includes the caller personalized ring back tone subscription and activation, and the information sent by the home HLR to the MSC is the supplementary service code (SS_CODE) of the personalized ring back tone; the MSC is calling. During the connection process, the SS-CODE is taken to the Service Control Point (SCP) to obtain the personalized ringback tone server address of the calling user, and is connected to the personalized ring back tone server according to the obtained server address. That is, when the calling user initiates a call, the calling MSC establishes a callback tone information based on the calling party's personalized callback tone information. The playback channel of the personalized ring back tone playback platform to which the user belongs, and the personalized ring back tone of the calling party is played by the personalized ring back tone playback platform. FIG. 3 is a flowchart of an implementation manner of an existing calling personalized ring back tone service. As shown in Figure 3, the following steps are included:

Steps L31 ~ L32: Normal call, the calling MSC sends a location request message to the called home HLR. Step L33: After the called home HLR receives the location request message, it sends a route request message to the called MSC.

Step L34: After receiving the location request message, the called MSC allocates a routing number to the called user, and carries it in the routing request response message and sends it to the called home HLR.

Step L35: The called home HLR sends a location request response message to the calling MSC.

Step L36: The calling MSC determines that the calling user subscribes to the calling personalized ring back tone service, sends a message to the calling personalized ring back tone playing platform, and establishes a calling personalized ring back tone branch.

Although the scheme implements the personalized ringback tone service of the calling party, it is only limited to be implemented by the calling MSC, and, in the prior art, if the same call is made, the calling party and the called party subscribe to the personalized ring back tone. The service, and possibly the main called party personalized ring back tone is triggered, thereby wasting the inter-office relay of the MSC to the personalized ring back tone playing platform, and if the user simultaneously signs the calling party and the called two personalized ringbacks The voice service cannot handle the problem of whether the call should be played by the ringing tone of the calling party's personalized ring back tone or the ringing tone of the called party's personalized ring back tone.

Step L134: After receiving the route request message, the called MSC saves the personalized ringback tone suppression information of the called party, and assigns a routing number to the called user, and carries it in the route request response message to return to the called home HLR.

Step L135: The called home HLR sends a location request response message to the calling MSC.

Step L136: The calling MSC determines that the personalized ringback tone branch of the called party needs to be established, and does not connect to the calling CRBT platform, and waits for the called MSC to establish a personalized ringback tone branch of the called party.

Step L137: The called MSC determines, according to the saved personalized ringback tone suppression information of the called party, that the personalized ringback tone branch of the called party needs to be established, and then connects to the called CRBT platform to establish a personalized ringback tone branch of the called party. .

(7) The calling MSC establishes a personalized ringback tone branch of the calling party, and the called MSC establishes a personalized ringback tone branch of the called party, and the calling MSC and the called MSC simultaneously determine the priority:

This method is a synthesis of the methods (2) and (3) described above, and will not be described again.

(8) The CRBT platform judges and plays:

The calling personalized ring back tone priority information and the called personalized ring back tone priority information are stored in their respective CRBT platforms; the calling CRBT platform and/or the called CRBT platform are personalized according to the calling party. The ringback tone priority information and the called personalized ringback tone priority information determine whether it is necessary to establish a calling personalized ring back tone branch or a called personalized ring back tone branch. The method specifically includes two cases: A. If the calling CRBT platform and the called CRBT platform are the same CRBT platform:

The CRBT platform determines whether it is necessary to establish a calling personalized ring back tone branch or a called personalized ring back tone branch according to the saved calling party personalized ring back tone priority information and the called personalized ring back tone priority information. B. The calling CRBT platform and the called CRBT platform are different CRBT platforms:

Both CRBT platforms play the sound, and the calling MSC preferentially establishes the calling party personalized ring back tone branch. If the calling user does not sign the calling party personalized ring back tone, the called personalized ring back tone branch or ordinary ring back tone is established. sound.

Alternatively, the calling CRBT platform determines whether the personalized ringback tone priority of the calling user is higher than the called user, and if so, establishes the calling personalized ring back tone branch; otherwise, does not establish any personalized ring back tone branch. .

(9) The calling MSC and the called MSC are different MSCs, and the called home HLR determines the priority, and the calling MSC establishes a personalized ring back tone branch according to the indication information:

The calling MSC requests location information of the called user from the called home HLR, and carries the personalized personalized ring back tone information in the location request message; the called home HLR receives and saves the calling party personalized back The ring tone information, according to the personalized ring back tone information of the calling party and the pre-saved personalized ring back tone information of the called party, determine whether it is necessary to establish a personalized ring back tone branch of the calling party or a personalized ring back tone branch of the called party, and at the location In the request response message, the indication information of whether the calling party personalized ring back tone is established is carried to the calling MSC.

FIG. 21 is a flowchart of a ninth solution of a method in which a calling party and a called user simultaneously subscribe to a personalized ring back tone service according to an embodiment of the present invention. As shown in Figure 21, the following steps are included:

Steps L211 ~ L212: Normal call, the calling MSC sends a location request message to the called home HLR.

Step L213: After receiving the location request message, the called home HLR sends a route request message to the called MSC, and saves the caller personalized ring back tone information of the calling user carried in the route request message.

Step L214: After receiving the routing request message, the called MSC allocates a routing number to the called user, and carries it in the routing request response message to return to the called home HLR.

Step L215: The called home HLR determines, according to the personalized ring back tone information signed by the calling party and the called party, whether to establish a personalized ringback tone branch of the calling party or the called party; meanwhile, the called home HLR sends a location request to the calling MSC. a response message, where the indication information indicating whether to establish a caller personalized ring back tone branch is carried;

Step L216: The calling MSC receives and saves the indication information in the location request response message from the called home HLR. If the indication information indicates that the calling personalized ring back tone branch needs to be established, the calling MSC To continue to call the CRBT platform, establish a caller personalized ringback tone branch; otherwise, do not establish a caller personalized ringback tone branch.

(10) The calling MSC and the called MSC are different MSCs, and the called home HLR determines the priority, and the called MSC establishes a personalized ring back tone branch according to the indication information:

The calling MSC requests the called home HLR to request the location information of the called user, and carries the calling personalized ring back tone information in the location request message; the called home HLR receives the calling personalized ring back tone The information, according to the personalized ring back tone information of the calling party and the pre-saved personalized ring back tone information of the called party, determine whether it is necessary to establish a personalized ring back tone branch of the calling party or a personalized ring back tone branch of the called party, and in the routing request message The carrying information indicating whether the called personalized ring back tone is established is sent to the called MSC.

FIG. 22 is a flowchart of a tenth solution manner when a calling party and a called user simultaneously subscribe to a personalized ring back tone service according to an embodiment of the present invention. As shown in Figure 22, the following steps are included:

Step L221 ~ L222: The ordinary call, the calling MSC sends a location request message to the home HLR, and in the message, the information of the personalized ringback tone of the calling party subscribed by the calling user is brought to the called home HLR; Step L223: Called The home HLR determines, according to the information of the personalized ring back tone subscribed by the calling party and the called party, that the personalized ringback tone of the calling party or the called party needs to be triggered, and indicates whether to establish the personalized ringing tone of the called party. The request message is brought to the called MSC;

Step L224: The called MSC receives the route request message, saves the indication information, assigns the routing number to the called user, and returns the call to the called home HLR.

Step L225: The called home HLR sends a location request response message to the calling MSC.

Step L226: In the indication information of the called home HLR, if the instructed to establish the called personalized ring back tone branch, the called MSC connects to the called CRBT platform to establish a called personalized ring back tone branch; otherwise, does not establish The called party is personalized with a ringback tone branch.

In the above tenth and eleventh embodiments, the called home HLR may also send the indication information to the calling MSC and the called MSC, and the primary and the called MSC respectively perform the connection.

(11) User subscription control information, wherein the control information is used to indicate that the user only listens to the normal ring back tone when the user makes a call in the call, and does not listen to the ringback tone of the calling or called contract:

The control information is signed at the calling home HLR, and is sent to the calling MSC in the location registration class (location registration/qualification indication/qualification request) process, and the calling MSC saves the control information; the user signs the control information as long as the user When making a call during the call, even if the user signs the caller's personalized ring back tone, or the called user signs the called ringback tone, the user always hears the exchange. The normal ring back tone played by the heart.

If the calling party and the called user belong to the same switching center, if the calling user subscribes to the control information,

The MSC does not establish any personalized ring back tone branch;

If the calling and called users do not belong to the same switching center, FIG. 23 is a flowchart of the eleventh solution according to the embodiment of the present invention. As shown in Figure 23, the following steps are included:

Step L231 ~ L232: ordinary call, the calling MSC sends a location request message to the home HLR, and in the message, the control information signed by the calling user is brought to the called home HLR;

Step L233: The called home HLR sends the control information to the called MSC in the routing request message. Step L234: The called MSC receives the location request message, saves the control information, and assigns a routing number to the called user, and returns The called party belongs to the HLR;

Step L235: The called home HLR sends a location request response message to the calling MSC.

Step L236: If the calling user subscribes to the control information, the called MSC does not establish the called personalized ring back tone branch; otherwise, establishes the called personalized ring back tone branch.

The embodiment shown in Figures 7 ~ 13 and Figures 21 ~ 23 solves the conflict problem that may occur when both the calling user and the called user sign a personalized ring back tone service. In actual applications, it may happen that the same user simultaneously signs the calling and called personalized ring back tone services.

For example, a user simultaneously subscribes to the caller's personalized ring back tone service and the called personalized ring back tone service. The two personalized ring back tone servers (ie CRBT) have the same address, but the caller personalizes the ring back tone and is The ring tone of the personalized ring back tone is different. The user wants to play the ring tone of the calling personalized ring back tone when playing as the calling party, and plays the ringing tone of the called personalized ring back tone when the called party is called.

In the prior art, the "personalized ring back tone server address" + "the user number of the personalized ring back tone is to be played" is used to notify the CRBT platform to play the personalized ring back tone, but the CRBT platform does not know that the personalized play needs to be played. The user who rings the ring tone is currently called as the calling or called, so the corresponding personalized ring back tone cannot be played correctly. For example: User A ( 13312345678 ) has signed the caller's personalized ring back tone and the called personalized ring back tone at the same time. The personalized ring back tone and tone server address is 8899, and the caller's personalized ring back tone is ringing. For MUSIC1, the ringing tone of the called personalized ring back tone is MUSIC2, and the calling party personalized ring back tone is signed first. So whether the user A is the calling or the called, the CRBT platform obtains the number 889913312345678, so the CRBT platform does not know whether to play MUSIC 1 or MUSIC2.

In response to this problem, the embodiment of the present invention provides a solution, namely: the calling MSC or the called party The MSC notifies the calling CRBT platform that the call needs to play the ringing tone of the calling personalized ring back tone or the ringing tone of the called personalized ring back tone. The specific implementation is as follows:

When the calling MSC or the called MSC sends a playback request to the CRBT platform, the extended cell that is requested by the playback or the newly defined flag in the existing cell carries the playback and needs to play the personalized ringback tone of the calling party. The ring tone is also the notification information of the ring tone of the called personalized ring back tone; the CRBT platform plays the ring tone of the calling personalized personalized ring back tone or the called personalized ring back tone according to the received notification information.

Alternatively, when the calling MSC or the called MSC sends a playback request to the CRBT platform, a specific number is inserted in the number or routing number of the identified user to identify whether the ringing tone of the calling party's personalized ring back tone should be played. The ringing tone of the personalized ring back tone is called; the CRBT platform plays the ringing tone of the calling personalized personalized ring back tone or the called personalized ring back tone according to the inserted specific number.

For example: You can use the "Personalized Ringback Tone Server Address" + "User Number to Play Personalized Ringback Tone" to notify the CRBT platform to play the personalized ringback tone in the prior art. The ringback tone server address "+" is the user number to play the personalized ringback tone. The "prefix" is used to indicate whether the user who wants to play the personalized ring back tone is called as the calling party or the called party during the call, so that the CRBT platform can determine which ring tone needs to be played.
