Description

Information transmission method, device and equipment

Technical Field

The present invention relates to the field of communications technologies, and in particular, to an information transmission method, apparatus, and device.

Background

In existing IP multimedia subsystem (IP Multimedia Subsystem, IMS), various logical entities providing media functions are defined, such as: SBC (session border controller) -U (user plane), P-CSCF (proxy call session control function), UMF (unified media processing network element), AS (application server), MRFP (multimedia resource processor), IM-MGW (IP multimedia gateway), etc., and corresponding control plane logical entities.

Wherein SBC-U can only be used by the matched P-CSCF control plane logic function, UMF can only be used by AS and other devices.

However, in the existing system architecture, each media function is independent, when multiple media functions are needed to be used in one session, a media stream (for example, a real-time transport protocol RTP or a real-time transport control protocol RTCP stream) of a user needs to flow between multiple logic entities, which not only increases the time delay, packet loss and jitter probability of forwarding the media stream, but also increases the overhead of system equipment.

For example, when both the current P-CSCF and the AS need to perform media processing, the media flow of the user is: UE 1- & gtSBC-U1- & gtUMF 2- & gtSBC-U2- & gtUE 2. If the SBC-U and UMF can be integrated into a logical functional entity (called an integrated media plane: convergence Media Function, CMF), the user's media flow can be reduced to: UE 1- & gt CMF1- & gt CMF2- & gt UE2, greatly improves the forwarding efficiency of the media stream, and is suitable for applications such as meta-universe.

However, if the media planes are fused, the behaviors of the control network elements for media plane selection are not perceived by each other, which may cause that the fused media planes selected by the network elements are not the same (for example, after the P-CSCF selects to use the fused media plane CMF, the AS does not perceive, which may cause that the fused media plane selected by the AS and the fused media plane selected by the P-CSCF are not the same), so that the goal of improving the media stream forwarding efficiency cannot be achieved.

Therefore, the prior art has the problem that each control network element cannot be supported to accurately select the same converged media plane CMF.

The information transmission method provided by the embodiment of the invention is illustrated below.

Aiming at the technical problems, the embodiment of the invention provides an information transmission method, which can be concretely realized as a scheme for sharing a fusion media surface by multiple devices, and relates to the following steps: the synchronization of the 'fusion media plane selection rule' is added in the registration process, and the synchronization of the 'fusion media plane selection' information is added in the call process, so that the same 'fusion media plane' is selected by the P-CSCF and the AS; in addition, under the condition that the information of the selected converged media plane carried in the call request is lost, the P-CSCF and the AS select the same converged media plane through icid (charging identification) information in a Session Initiation Protocol (SIP) session, so that the problem that network elements of different control planes select the same media plane after a plurality of media plane devices are converged is solved. The details of the matters are specifically exemplified below.

Example 1: a first synchronization process of fusing media plane selection rules (corresponding to the fused media plane device selection rules described above).

As shown in fig. 8, the present embodiment includes the following steps:

1. The terminal sends an initial SIP REGISTER (registration) request to the P-CSCF;

The p-CSCF inserts an extension parameter (e.g. + g.media) in the Contact header of the SIP REGISTER request, indicating that control of the converged media plane is supported (i.e. insert a support "media plane sharing" capability indication in the Contact header), and then forwards SIP REGISTER the request to the I-CSCF;

the I-CSCF interacts with HSS (home subscriber service) to acquire S-CSCF information;

the i-CSCF forwards SIP REGISTER the request to the S-CSCF (based on the acquired S-CSCF information);

5.S-CSCF interacts with HSS to obtain authentication information;

6.S-CSCF returns 401 response (error response) to I-CSCF, carrying authentication information;

7.I-CSCF forwards 401 the response to the P-CSCF;

8.P-CSCF forwards 401 the response to the terminal;

9. the terminal sends an initial registration request (SIP REGISTER) to the P-CSCF, wherein authentication information is carried;

The p-CSCF inserts an extension parameter (e.g. + g.media) in the Contact header of the SIP REGISTER request, indicating that control of the converged media plane is supported, and then forwards SIP REGISTER the request to the I-CSCF;

the I-CSCF and the HSS are interacted to acquire S-CSCF information;

The i-CSCF forwards SIP REGISTER the request (carrying the authentication information in step 9) to the S-CSCF; steps 9-12 may correspond to the P-CSCF device receiving a third registration request sent by the terminal; sending a second registration request to the S-CSCF equipment according to the third registration request; the second registration request carries first indication information of the P-CSCF equipment supporting the control of the converged media plane equipment and can also carry authentication information of the terminal. The S-CSCF device obtains authentication information of the terminal (which may be carried in the second registration request).

After the S-CSCF completes the authentication and verification of the user, the S-CSCF interacts with the HSS to update the association relation (between the S-CSCF and the user), saves the association relation between the S-CSCF and the user, and downloads information such as iFC (INITIAL FILTER CRITERIA, initial filtering rule) triggering rules of the user; and the authentication verification can be carried out on the terminal according to the authentication information corresponding to the S-CSCF equipment.

The s-CSCF sends a 200OK response (success response) to the I-CSCF;

The I-CSCF forwards the 200OK response to the P-CSCF;

the P-CSCF forwards the 200OK response to the terminal;

The S-CSCF sends a third party registration request (SIP REGISTER) to the application server AS, wherein the third party registration request carries an expansion parameter supporting the control of the converged media plane; sending a first registration request to an application server corresponding to the condition that the authentication verification is passed by the S-CSCF equipment; the application server receives a first registration request sent by a service call session control function (S-CSCF) device, wherein the first registration request carries first indication information for supporting control of a converged media surface device by a proxy call session control function (P-CSCF) device.

18. The application server extracts an expansion parameter supporting the control of the fusion media surface from the third party registration request and returns a 200OK response; and sending a second confirmation response aiming at the first registration request to the S-CSCF equipment by the application server.

19. The application server sends a notification message (SIP MESSAGE) to the P-CSCF through the I-CSCF, carrying a 'converged media plane selection rule'; sending a first notification message to the P-CSCF equipment according to the first indication information corresponding to the application server; the first notification message carries a fusion media plane device selection rule; the P-CSCF equipment receives a first notification message sent by an application server; the first notification message carries a fused media plane device selection rule.

The P-CSCF returns a 200OK response to the application server through the I-CSCF; transmitting a first acknowledgement response to the application server corresponding to the P-CSCF device; and the application server receives a first confirmation response sent by the P-CSCF equipment.

Thus, the first synchronization of the fusion media plane selection rule is completed between the P-CSCF and the application server.

Example 2: fusing the updating flow of the media plane selection rule;

As shown in fig. 9, the present embodiment includes the following steps:

1. When the application server finds that the "converged media plane selection rule" has changed, a notification message (SIP MESSAGE) is sent to the I-CSCF, carrying the full-size information of the "converged media plane selection rule", such as rule contents selected according to the location information of the terminal, the media type (audio or video) of the call, the service feature tag in the call request (e.g., information in the Contact or Accept-Contact header), and so on.

The I-CSCF sends a notification message (SIP MESSAGE) to the P-CSCF, carrying the full-quantity information of the 'converged media plane selection rule'; step 1-2 may correspond to the application server sending a second notification message to the P-CSCF device after the converged media plane device selection rule is updated; the second notification message indicates updated fusion media surface device selection rules; the P-CSCF equipment receives a second notification message sent by an application server; the second notification message indicates the updated converged media surface device selection rule.

And 3.P-CSCF updates the rule (corresponding to the updated fused media plane device selection rule obtained by the P-CSCF device according to the second notification message) and returns a 200OK response to the I-CSCF.

The i-CSCF returns a 200OK response to the application server.

To this end, the data update of the "converged media plane selection rule" is completed between the P-CSCF and the application server.

Example 3: when a terminal initiates a call, each network element of a calling side network performs a selection process on the converged media surface;

as shown in fig. 10, the present embodiment includes the following steps:

1. A terminal (UE-A) initiates an initial call request (INVITE) to a P-CSCF (O) in the corresponding diagram, namely a calling P-CSCF); the method can correspond to an eighth call request sent by the P-CSCF equipment receiving terminal, wherein the eighth call request carries session association information; wherein the terminal (UE-a) is understood to be the calling terminal.

And 2, the P-CSCF selects a proper fusion media plane CMF according to the fusion media plane selection rule acquired during registration. The judging condition may include, but is not limited to, location information of the terminal, media type (audio or video) of the call, service feature tag (e.g., information in Contact or Accept-Contact header) in the call request, etc.; the method can select target fusion media plane equipment according to the fusion media plane equipment selection rule corresponding to the P-CSCF equipment; the target fusion media surface device is a first fusion media surface device.

The 3.P-CSCF interacts with the selected converged media plane to apply for media resources, which may specifically include: applying for a converged media plane Context (Context) resource and applying for a media forwarding resource (RTP, RTCP, etc.); when applying, the information (corresponding to the session association information) such as icid information and caller side identification in the INVITE request needs to be carried, so as to realize the association between the media resource and the SIP session; the returned result of the fusion media plane contains the context URI (Uniform resource identifier) distributed by the fusion media plane and various forwarding resource information; a second application request can be sent to the first converged media surface device corresponding to the P-CSCF device, and the second application request carries the session association information; the converged media plane device receives a second application request sent by the P-CSCF device, wherein the second application request carries session association information; sending a second application response to the P-CSCF equipment according to the session association information, wherein the second application response carries the first URI information and the first resource information of the converged media surface equipment; the P-CSCF equipment receives a second application response sent by the first fused media surface equipment, wherein the second application response carries first URI information and first resource information of the first fused media surface equipment, and the first resource information is information of resources applied by the P-CSCF equipment.

A specific example of a request for applying for a media forwarding resource may be as follows:

4.P-CSCF puts URI information fused with the media plane into the extension header of the INVITE request and forwards it to S-CSCF (O) in the corresponding figure, i.e. calling S-CSCF); a seventh call request can be sent to the S-CSCF equipment according to the second application response corresponding to the P-CSCF equipment, and the seventh call request carries the first URI information; and the S-CSCF equipment receives a seventh call request sent by the P-CSCF equipment, wherein the seventh call request carries first URI information of the first converged media surface equipment selected by the P-CSCF equipment according to the converged media surface equipment selection rule. An example of an extension header may be as follows:

X-MO-Media-URI (calling Media URI): http://10.42.118.60:9090/context/01; the above parameters represent URI information of the converged media plane in the current session (i.e., the SIP session of step 3).

The 5.S-CSCF triggers (i.e. sends the INVITE request) to the first application server AS1 after receiving the INVITE request according to the user subscription (the subscription is available from the HSS); the S-CSCF equipment sends a first call request to a target server according to the seventh call request, wherein the first call request carries the first URI information; the target server is the application server; and the application server receives a first call request sent by the S-CSCF equipment, wherein the first call request carries first Uniform Resource Identifier (URI) information of a first converged media surface equipment selected by the P-CSCF equipment according to the converged media surface equipment selection rule.

6. When receiving the INVITE request, the first application server AS1 determines that the INVITE request carries information fusing the media plane, and then uses the media plane to perform resource operation preferentially. The application server initiates a query request to the media plane (to query for the applied resources), such as: GET HTTP://10.42.118.60:9090/context/01; the application server sends a first resource query request to the first converged media surface device according to the first URI information; and the converged media surface equipment receives a first resource query request sent by the application server.

7. The fusion media surface returns the media forwarding resource information applied by the P-CSCF to the first application server (through response); the method comprises the steps that first resource information is sent to an application server corresponding to the converged media plane equipment, wherein the first resource information is information of resources applied by P-CSCF equipment; and the application server receives first resource information sent by the first converged media plane device, wherein the first resource information is information of resources applied by the P-CSCF device. Examples of the response sent by the converged media plane may be as follows:

8. According to the business logic, the first application server AS1 can apply for new resources from the converged media surface (initiate request) by using the resource URI of the converged media surface; determining whether to apply for a second resource to the first converged media surface device according to the first resource information corresponding to the application server; if yes, applying for a second resource to the first converged media surface device according to the first URI information and the first resource information; the converged media plane device receives a resource application request sent by an application server, wherein the resource application request is an application request for a second resource.

The request for applying for new resources may be, for example: POST HTTP://10.42.118.60:9090/context/01/mixer;

9. The fusion media surface returns the newly applied resource information to the first application server (through response); the method comprises the steps that a resource application response is sent to an application server corresponding to the converged media surface equipment, wherein the resource application response is resource information of a second resource; and the application server receives the resource information of the second resource sent by the first fusion media surface equipment. Examples of responses (carrying resource information of a new application) sent by the converged media plane may be as follows:

10. The first application server AS1 forwards the INVITE request to the S-CSCF, wherein the URI of the converged media plane resource is still carried; transmitting a second call request (in this case, the request may correspond to a seventh call request) to the S-CSCF device according to the resource information of the second resource, where the second call request carries the first URI information; and the S-CSCF equipment receives a seventh call request sent by the application server, wherein the seventh call request carries first URI information of the first converged media surface equipment selected by the P-CSCF equipment according to the converged media surface equipment selection rule.

The S-CSCF continues to trigger the second application server AS2 according to the subscription of the user, and the fused media plane resource URI is carried in the forwarded request; the method also can be corresponding to the S-CSCF equipment, and according to the seventh call request, a first call request is sent to a target server, wherein the first call request carries the first URI information; the target server is another server except the application server; the operation of the AS2 may be similar to that of the above application server receiving a first call request sent by the S-CSCF device, where the first call request carries first uniform resource identifier URI information of a first converged media plane device selected by the P-CSCF device according to the converged media plane device selection rule. Wherein AS1 and AS2 may correspond to different services, such AS one voice service, another video service, etc.

12. When the second application server AS2 receives the INVITE request, judging that the INVITE request carries information fusing the media surface, and preferentially using the media surface to perform resource operation; the second application server initiates a query request to the media plane (to query for the applied resources), for example: GET HTTP://10.42.118.60:9090/context/01; a first resource query request may be sent to the first converged media plane device according to the first URI information corresponding to the application server.

13. The fusion media surface returns the applied resource information in the current session to the second application server (through response); the application server may receive first resource information sent by the first converged media plane device, where the first resource information is information of a resource applied by another application server. Examples of the response sent by the converged media plane may be as follows:

14. The second application server judges that the required resource is applied according to the service logic, and does not apply any more, forwards the INVITE request to the S-CSCF (O), wherein the URI of the fusion media surface resource of the calling side is still carried; determining whether to apply for a second resource to the first converged media surface device according to the first resource information corresponding to the application server; if not, directly sending a second call request to the S-CSCF equipment, wherein the second call request carries the first URI information; and the S-CSCF equipment receives a second call request sent by the target server, wherein the second call request carries the first URI information. The S-CSCF (O) represents the calling S-CSCF.

And checking the subscription of the user by the S-CSCF, judging that the calling side does not have an application server needing triggering, and thus, finishing the selection of the fusion media surface of the calling side and the application of related resources.

Example 4: when a terminal initiates a call, each network element of the called side network performs a selection process of the converged media surface;

The called side application server can check whether the calling side converged media surface resource URI carried in the INVITE request meets the requirement, if so, the called side application server can be directly used, and the specific flow can be seen in the embodiment 3; if the requirements are not met, the fusion media surface selection can be carried out again according to the service logic of the user. The embodiment describes a scenario that does not meet the requirement, and may specifically be shown in fig. 11, where the embodiment includes the following steps:

1. The called side S-CSCF (T) triggers the INVITE (carrying the X-MO-Media-URI) received from the S-CSCF (O) to the third application server AS3 according to the subscription of the called user; a fourth call request can be sent to the application server corresponding to the S-CSCF equipment, and the fourth call request carries first URI information of the first converged media surface equipment; and the application server receives a fourth call request sent by the S-CSCF equipment, wherein the fourth call request carries the first URI information of the first converged media surface equipment.

3. The third application server AS3 interacts with the (selected) converged media plane (B), initiates a request to apply for new resources, and may include: creating a context resource for the called user B and applying for a media forwarding resource; a first application request can be sent to the second converged media surface device corresponding to the application server; the converged media plane device receives a resource application request sent by an application server; the resource application request is a first application request.

The P-CSCF (T) checks that the INVITE request carries the fused media plane resource URI of the called side, and directly uses the fused media plane resource URI to avoid the selection of the fused media plane; acquiring the applied media plane resources (namely inquiring the applied resources, which can be realized by initiating GET HTTP and receiving 200 OK) through interaction with the called side fusion media plane (B); the P-CSCF device may receive a third call request sent by the S-CSCF device, where the third sixth call request carries second URI information of the second converged media plane device; according to the second URI information, a fourth resource query request is sent to the second converged media plane device; the converged media plane device receives a fourth resource query request sent by the P-CSCF device; sending a second query response to the P-CSCF equipment, wherein the second query response carries fourth resource information, and the fourth resource information is information of resources applied by another application server; the P-CSCF equipment receives a second query response sent by the second converged media plane equipment; the second query response carries fourth resource information, wherein the fourth resource information is information of resources applied by another application server (AS 3).

The P-CSCF (T) interacts with the converged media plane (B) (initiates a request to update the existing resources, applies for media information (IP address, port number, codec, etc.) connected with the (called) terminal; a third application request can be sent to the second converged media plane device corresponding to the P-CSCF device, where the third application is used to request media information required for connection with a terminal; and the converged media plane device receives a third application request sent by the P-CSCF device, wherein the third application is used for requesting media information required by connection with the terminal. The request sent by the P-CSCF (T) to the converged media plane (B) may be exemplified as follows:

12. The fusion media surface (B) returns media information (IP address, port number, codec, etc.) connected with the terminal through response; a third application response can be sent to the P-CSCF equipment corresponding to the fused media plane equipment, and the third application response carries the media information; and the P-CSCF equipment receives a third application response sent by the second converged media surface equipment, wherein the third application response carries the media information. The response sent by the converged media plane (B) may be exemplified as follows:

The P-CSCF (T) carries the Media information connected with the terminal in the INVITE request sent to the terminal (B), and deletes the relevant extension header (for example, X-MO-Media-URI and X-MT-Media-URI) fusing the Media face URI information, namely, the request sent to the terminal does not carry the extension header; a ninth call request may be sent to the terminal according to the media information corresponding to the P-CSCF device. Wherein the terminal (B) can be understood as a called terminal.

So far, the selection and application of the fusion media surface are completed in the called side call flow, and the sharing of media resources is realized.

The media plane selection of the calling party and the called party can be two independent processes, and different media planes are respectively selected, but the method is not limited thereto.

Example 5: the calling side application server does not receive the processing of the converged media plane URI in the INVITE request;

Specifically, the extension header may be deleted by the S-CSCF (O) or other application server, so that the calling side application server does not receive the converged media plane URI generated by the P-CSCF (O) in the INVITE request (for example, "the INVITE request carries the information of the converged media plane" in step 6 in embodiment 3, and adjusts that the INVITE request does not carry the information of the converged media plane); for this case, as shown in fig. 12, the present solution may further include the following operations:

1. The application server uses the fusion media surface selection rule to select the media surface; corresponding to the situation that the first call request does not carry the first URI information, determining a third converged media plane device according to the converged media plane device selection rule; the third converged media surface device is the same as or different from the first converged media surface device; specifically, for example, in fig. 12, the INVITE received by the AS1 does not carry an X-MO-Media-URI, and the AS1 may select according to the fused Media plane selection rule; or AS2 in fig. 12 receives an INVITE that does not carry an X-MO-Media-URI, AS2 may select according to the fused Media plane selection rule.

2. The application server performs resource query on the selected converged media surface, and the used resource URI (namely URI carried by the query request) contains icid information in the SIP session, for example, GET http:// cmf01.Xxx. Com/resourceIcid = fexdefe; a third resource query request may be sent to the third converged media plane device in correspondence with the foregoing; the third resource query request carries third URI information containing charging identification information; the converged media plane device receives a third resource query request sent by an application server; the third resource query request carries third URI information including charging identification information. Specifically, for example, AS1 in fig. 12 initiates a request to a selected converged media plane 1 (e.g., GET HTTP carrying icid), and for example, AS2 in fig. 12 initiates a request to a selected converged media plane 2 (e.g., GET HTTP carrying icid).

3. The fusion media surface inquires whether the created resource contains a designation icid, if yes, the returned response contains the applied resource (which can be the resource applied by the P-CSCF); if not, a response is returned 404; determining whether the created resource contains the resource corresponding to the icid information or not according to the fusion media plane device to obtain a first determination result; according to the first determination result, a first query response is sent to the application server; the first query response carries fifth resource information, or the first query response indicates that resources are not applied for; the application server receives a first query response sent by the third converged media surface device; the first query response carries fifth resource information, or the first query response indicates that resources are not applied for. Specifically, for example, the converged media plane 1 in fig. 12 sends a 200OK (including the applied resources) to the AS 1; also such AS converged media plane 2 in fig. 12, sends 404 a response to AS2 (indicating that the created resource does not contain designation icid).

4. The application server directly uses the fusion media plane resource information if the fusion media plane resource information is returned according to the returned result of the resource query (specifically, for example, AS1 in FIG. 12 uses the existing resource according to 200 OK); if the fused media plane resource information is not returned, the fused media plane resource information is newly applied (specifically, for example, the AS2 in FIG. 12 applies for new resources to the fused media plane 2, which can be realized by initiating POST HTTP and receiving 200 OK); and applying for a sixth resource to the third converged media surface device in response to the application server indicating that no resource is applied for by the first query response.

For further details, reference is made to embodiment 3 in fig. 12, and details are not repeated here.

Example 6: the called side P-CSCF (T) does not receive the processing of the converged media plane URI in the INVITE request;

Specifically, the extension header may be deleted by the S-CSCF (T) or other application server, so that the called P-CSCF (T) does not receive the converged media plane URI generated by the called application server in the INVITE request; for this case, as shown in fig. 13, the present solution may further include the following operations:

1.P-CSCF (T) selects a media plane using the synchronized converged media plane selection rules at registration (see example 1); corresponding to the P-CSCF device determining a fourth converged media plane device according to the converged media plane device selection rule when the third call request does not carry the second URI information; the fourth converged media surface device is the same as or different from the second converged media surface device;

The P-CSCF (T) inquires the resources (namely inquires the applied resources) of the selected fusion media surface, and the used resources uri comprise icid information in the SIP session, for example, GET http:// cmf02.Xxx.com/resourceIcid = fexdefe; a fifth resource query request is sent to the fourth converged media plane device corresponding to the P-CSCF device; the fifth resource query request carries fourth URI information containing icid information; the converged media plane device receives a fifth resource query request sent by the P-CSCF device; the fifth resource query request carries fourth URI information including icid information.

3. The fusion media surface inquires whether the created resource contains a designation icid, if yes, the returned response contains the applied resource (corresponding to the feedback 200OK in FIG. 13, the applied resource can be the resource applied by AS 3); if not, a response is returned 404; determining whether the created resource contains the resource corresponding to the icid information or not according to the fused media plane device to obtain a second determination result; according to the second determination result, a third query response is sent to the P-CSCF equipment; the third query response carries seventh resource information, or the third query response indicates that resources are not applied for; the P-CSCF equipment receives a third query response sent by the fourth converged media plane equipment; the third query response carries seventh resource information, or the third query response indicates that no resource is applied.

The 4.P-CSCF (T) directly uses the information (corresponding to executing the subsequent operations of updating the existing resources and the like) if the information of the resources of the fused media plane is returned according to the returned result of the resource query; if the information of the fused media surface resource is not returned, the information of the fused media surface resource is newly applied; and applying eighth resources to the fourth converged media surface device under the condition that the third query response indicates that the resources are not applied.

For further details, reference is made to embodiment 4 in fig. 13, and details are not repeated here.

In addition, the related contents of the above embodiments can be referred to each other, and the repetition is not repeated. In addition, the fused media plane device can support the function of at least one device of the first fused media plane device, the second fused media plane device, the third fused media plane device and/or the fourth fused media plane device, but not limited thereto.

From the above, the scheme provided by the embodiment of the invention comprises:

1. through IMS registration flow, the method of synchronizing the 'converged media plane selection rule' between the P-CSCF and the AS is realized, so that the P-CSCF and the AS can select the same converged media plane, and the forwarding and processing efficiency of the media is improved. The synchronization process for fusing media plane selection rules specifically includes:

the P-CSCF can firstly acquire SIP REGISTER requests from the terminal, then interact with the HSS to acquire authentication information and send the authentication information to the terminal, and the P-CSCF inserts extension parameters in the Contact header; after the authentication verification is completed, the S-CSCF can store the association relationship between the S-CSCF and the user; the P-CSCF may then send the AS with the extension parameters of "support control of the converged media plane" and receive the converged media plane selection rules returned by the AS.

Further, the method may further include: the P-CSCF receives the total information of the 'fusion media plane selection rule' sent by the AS, updates the rule according to the information, and responds to the AS, wherein the total information is sent to the P-CSCF after the AS monitors that the fusion media plane selection rule changes.

2. The method of 'selected converged media surface' is carried by the extension header in the call request, so that the P-CSCF and the AS can use the same method of converged media surface in one session. Specific:

When a terminal initiates a call, a calling side can select the fusion media surface, then a called side application server can detect whether the resource URI of the fusion media surface carried by the calling side is satisfied, and if not, the called side can automatically reselect the fusion media surface. The interaction flow of the fusion media surface selected by the calling side and the called side is different.

When a terminal initiates a call, the selection processes of the network CSCF network element on the calling side and the network CSCF network element on the called side for the converged media surface are all applied based on the selection rule of the converged media surface, and the CSCF can reselect the converged media surface only when the URI carried in the INVITE request does not meet the requirement.

The 3.P-CSCF or AS carries icid information in the SIP session when creating the media asset. The method can further support that the P-CSCF or the AS can inquire the fusion media plane resource information applied before under the condition that the selected fusion media plane information carried in the call request is lost. Specific:

If the calling side and the called side do not receive the converged media plane URI because the other network elements delete the expandable header, the converged media plane can query icid the resources, and the converged media plane can query whether the created resources contain the designation icid to determine whether the converged media plane resource information can be returned.

The processing manners of the calling side AS and the called side CSCF when the converged media plane URI is not received in the INVITE request may include: and inquiring that the resource contains the designation icid based on the selected fusion media plane so as to obtain the fusion media plane resource information.

In summary, the scheme provided by the embodiment of the invention has the following advantages:

1. The P-CSCF and the AS can be ensured to select the same fusion media plane. Specifically, the synchronization of the information of the 'fusion media plane selection' is added in the call flow by adding the synchronization of the 'fusion media plane selection rule' in the registration flow, so that the same 'fusion media plane' selected by the P-CSCF and the AS is supported.

2. A method for P-CSCF and AS to select the same fusion media plane is provided under the condition that the information of the selected fusion media plane carried in the call request is lost.

In addition, the scheme can be applied to the service scene of the fusion media surface, can effectively improve the media stream forwarding efficiency, greatly improve the user experience, and has very wide application scenes.
