[0069] The present application will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0070] The IP Multimedia Subsystem (IMS) is the core network for real-time communication services in 4G and 5G networks. It provides functions such as session establishment, service triggering, and media processing for Voice over Long-Term Evolution (VoLTE) and Voice over New Radio (VoNR).

[0071] In an IMS network, in order to transmit real-time media streams between relevant endpoints (terminals or network devices), media negotiation needs to be performed between the relevant endpoints beforehand. This is achieved by encapsulating Session Description Protocol (SDP) content in SIP messages and transmitting SIP messages between the relevant endpoints.

[0072] In an IMS network, media negotiation is required in the following scenarios: (1) between terminals, used to transmit call media between terminals during actual calls; (2) between terminals and service platforms, used for playing service-related media, such as ringback tones and notification tones. When multiple service platforms are involved between two terminals in a call, multiple media negotiations are usually required during the call. Improper handling of multiple media negotiations will lead to service failure. Figure 1 This is a schematic diagram illustrating a scenario where a new call service is overlaid on a ringback tone service, as provided in an embodiment of this application. Figure 1 In the process, the 200 OK message sent by the called user (UE-B) after answering the phone first reaches the new call application server (AS), triggering it to initiate media negotiation for media plane anchoring (because it needs to process the call media stream subsequently). However, when the relevant SIP messages are forwarded to the ringback tone service platform, the ringback tone service platform is unaware that the called user has answered the phone (the 200 OK message has not yet been forwarded to the ringback tone platform), therefore the ringback tone platform does not forward the SDP message to the calling side (UE-A). After the ringback tone platform receives the 200 OK message, it initiates media renegotiation again to remove the ringback tone platform from the media path (because the ringback tone platform is no longer needed for media stream processing during the call).

[0073] Based on this, the embodiments of this application add SIP message parameters, enabling the purpose of multiple media negotiations to be achieved in a single SIP interaction, thereby reducing network signaling overhead.

[0074] This application provides a media negotiation method. Figure 2 This application provides a flowchart illustrating a media negotiation method, applicable to a network device equipped with multiple service platforms; such as... Figure 2 As shown, it includes:

[0075] Step 201: Receive a first message sent by the called terminal; based on the first message, trigger the first service platform among the plurality of service platforms to send a second message to the second service platform; the second service platform is any service platform among the plurality of service platforms other than the first service platform; the second message includes SIP message parameters; the SIP message parameters are used to indicate the time point of the media renegotiation during the call and the service that triggers the media renegotiation when media renegotiation is initiated;

[0076] Step 202: Determine the processing strategy of the second service platform based on the SIP message parameters;

[0077] Step 203: Based on the processing strategy, send the second message to the calling terminal to complete the media renegotiation.

[0078] It should be noted that the multiple service platforms can be any type of service platform, which can be determined according to the actual situation, and is not limited here. As an example, the multiple service platforms include ringback tones AS and new call AS, etc. The number of service platforms can be determined according to the actual situation, and is not limited here.

[0079] The terminal can be any terminal capable of communication, and there is no limitation herein. As an example, the terminal can be a user equipment (UE). In practical applications, the terminal can also be called a mobile phone.

[0080] In step 201, the called terminal can be referred to as the called terminal. The first message can be understood as any status message corresponding to the called terminal sent by the called terminal, which can be determined according to the actual situation and is not limited here. As an example, the first message includes a message that the called terminal has answered the phone, or a message that the called terminal is ringing, or a message that the called terminal has rejected the call.

[0081] The first service platform can be understood as any platform that initiates media renegotiation, and can be determined according to the actual situation; no limitation is made here. As an example, the first service platform can be a new call AS. The first service platform can be any service platform other than the first service platform, and can be determined according to the actual situation; no limitation is made here. As an example, the second service platform can be a ringback tone AS.

[0082] The second message can be understood as a media renegotiation message sent by the first service platform to the second service platform; the second message includes SIP message parameters.

[0083] The time points include at least one of the following: the time point corresponding to the ringing of the called terminal; the time point corresponding to the answering of the called terminal; the time point corresponding to the rejection of the called terminal. The services include at least one of the following: new call service; custom ringback tone service.

[0084] It should be noted that the service platform that initiates media renegotiation is the service that triggers media renegotiation in the SIP message parameters. For ease of understanding, here is an example: after receiving the message that the called terminal has answered the call, the New Call AS initiates media renegotiation to the Ringback Tone AS. The New Call AS sends a media renegotiation message to the Ringback Tone AS, which includes SIP message parameters, denoted as [answered, New Call].

[0085] In step 202, the processing strategy includes at least one of the following: directly forwarding the second message to the called terminal; modifying the endpoint of the second service platform based on the SIP message parameters; and modifying the codec type of the second service platform based on the SIP message parameters.

[0086] The step of determining the processing strategy of the second service platform based on the SIP message parameters can be understood as processing the second service platform according to the indication information in the SIP message parameters.

[0087] In step 203, the terminal making the call can be referred to as the calling terminal. Sending the second message to the calling terminal based on the processing strategy to complete the media renegotiation can be understood as sending the second message to the calling terminal based on the processing strategy, so that the calling terminal can complete the media renegotiation according to the second message.

[0088] In the scheme of this application embodiment, the network device receives a first message sent by the called terminal, and triggers a first service platform to send a second message to a second service based on the first message. The second message includes SIP message parameters. That is, by adding SIP message parameters, the purpose of multiple media negotiations can be achieved in one SIP interaction, thereby reducing network signaling overhead.

[0089] In one embodiment, the time point includes at least one of the following:

[0090] The time point corresponding to the ringing of the called terminal;

[0091] The time point at which the called terminal goes off the phone;

[0092] The time point at which the called terminal rejects the call.

[0093] The time points corresponding to the ringing of the called terminal, the answering of the called terminal, and the rejection of the called terminal can be determined according to the actual situation and are not limited here.

[0094] In one embodiment, the service includes at least one of the following:

[0095] New call services;

[0096] Ringback tone service.

[0097] The services mentioned may include new call services and ringback tone services. The number of services included in the services can be determined according to the actual situation and is not limited here. It should be noted that the order of the services during media negotiation can be determined according to the actual situation and is not limited here.

[0098] In one embodiment, the processing strategy includes at least one of the following:

[0099] The second message is forwarded directly to the called terminal;

[0100] The endpoint of the second service platform is modified based on the SIP message parameters;

[0101] The encoding / decoding type of the second service platform is modified based on the SIP message parameters.

[0102] Specifically, forwarding the second message directly to the called terminal can be referred to as pass-through; modifying the endpoint of the second service platform based on the SIP message parameters can be referred to as modifying the media endpoint; and modifying the codec type of the second service platform based on the SIP message parameters can be referred to as modifying the codec type.

[0103] In one embodiment, after sending the second message to the calling terminal, the method further includes:

[0104] A third message sent by the terminal receiving the call; the third message includes first parameter information determined by the terminal making the call based on the second message;

[0105] Based on the first parameter information, the first message is forwarded to the terminal of the call to release the media plane.

[0106] The first parameter information can be any parameter information supported by the calling terminal as determined by the second message, including the address information, port information, and supported frequency band information of the calling terminal.

[0107] In one embodiment, before receiving the first message sent by the called terminal, the method further includes:

[0108] A fourth message sent by the terminal receiving the call; the fourth message includes the second parameter information of the terminal making the call;

[0109] The second parameter information is forwarded to the called terminal; the second parameter information is used by the called terminal to determine the third parameter information of the called terminal based on the second parameter information.

[0110] Receive a fifth message sent by the called terminal, the fifth message including the third parameter information;

[0111] Based on the third parameter information, the terminal making the call executes playback of at least one of the multiple service platforms.

[0112] The second parameter information can be all the parameter information of the calling terminal itself, including address information, port information, and all supported frequency bands. The third parameter information can be understood as the parameter information that the called terminal selects from the second parameter information that it supports.

[0113] The step of playing at least one of the multiple service platforms to the calling terminal based on the third parameter information can be understood as the ringback tone AS playing ringback tone media to the calling terminal after receiving the fifth message sent by the called terminal.

[0114] Accordingly, embodiments of this application also provide a media negotiation method. Figure 3 A flowchart illustrating another media negotiation method provided in this application embodiment is shown below. Figure 3 As shown, it is applied to the terminal and includes:

[0115] Step 301: Send a first message to a network device configured with multiple service platforms. The first message triggers a first service platform among the multiple service platforms to send a second message to a second service platform. The second service platform is any service platform among the multiple service platforms other than the first service platform. The second message includes SIP message parameters. The SIP message parameters indicate the time point during the call when media renegotiation is initiated and the service that triggers the media renegotiation. Determine the processing strategy of the second service platform based on the SIP message parameters.

[0116] Step 302: Receive the second message sent by the second service platform based on the processing strategy to complete the media renegotiation.

[0117] It should be noted that the multiple service platforms can be any type of service platform, which can be determined according to the actual situation, and is not limited here. As an example, the multiple service platforms include ringback tones AS and new call AS, etc. The number of service platforms can be determined according to the actual situation, and is not limited here.

The terminal includes a called terminal and a calling terminal; the called terminal can be called the called terminal, and the calling terminal can be called the calling terminal.

[0119] In step 301, the first message can be understood as any status message corresponding to the called terminal sent by the called terminal, which can be determined according to the actual situation and is not limited here. As an example, the first message includes a message that the called terminal has answered the phone, or a message that the called terminal is ringing, or a message that the called terminal has rejected the call.

[0120] The first service platform can be understood as any platform that initiates media renegotiation, and can be determined according to the actual situation; no limitation is made here. As an example, the first service platform can be a new call AS. The first service platform can be any service platform other than the first service platform, and can be determined according to the actual situation; no limitation is made here. As an example, the second service platform can be a ringback tone AS.

[0123] The services include at least one of the following: new call service; ringback tone service.

[0124] It should be noted that the service platform that initiates media renegotiation is the service that triggers media renegotiation in the SIP message parameters. For ease of understanding, here is an example: after receiving the message that the called terminal has answered the call, the New Call AS initiates media renegotiation to the Ringback Tone AS. The New Call AS sends a media renegotiation message to the Ringback Tone AS, which includes SIP message parameters, denoted as [answered, New Call].

[0125] The processing strategy includes at least one of the following: directly forwarding the second message to the called terminal; modifying the endpoint of the second service platform based on the SIP message parameters; or modifying the codec type of the second service platform based on the SIP message parameters.

[0126] The step of determining the processing strategy of the second service platform based on the SIP message parameters can be understood as processing the second service platform according to the indication information in the SIP message parameters.

[0127] In step 302, the second message sent by the second service platform is received based on the processing strategy to complete the media renegotiation; this can be understood as the calling terminal receiving the second message sent by the second service platform to complete the media renegotiation.

[0128] In the scheme of this application embodiment, the network device receives a first message sent by the called terminal, and triggers a first service platform to send a second message to a second service based on the first message.
