[0054] Based on the above embodiment, another embodiment of the present application provides a method for supporting metaverse services, which is applied to IMS. Figure 3 Schematic diagram of the method for supporting Metaverse services proposed in this embodiment Figure 1 ,like Figure 3As shown, the method for supporting metaverse services may include the following steps:

[0055] Step 101: A first network function in an IMS receives a first request sent by a fifth network function in the IMS; wherein the first request carries first information or second information.

[0056] In the embodiment of the present application, the first network function in the IMS may receive the first request sent by the fifth network function.

[0057] It should be noted that, in the embodiments of the present application, the first network function may be LAS, and the present application does not specifically limit the type of the first network function.

[0058] It should be noted that, in the embodiment of the present application, the fifth network function may be a P-CSCF, and the present application does not specifically limit the type of the fifth network function.

[0059] It should be noted that, in the embodiment of the present application, the first information at least includes the location information of the UE, and the present application does not specifically limit the type and quantity of information included in the first information.

[0060] It should be noted that, in the embodiment of the present application, the second information at least includes the updated location information of the UE, and the present application does not specifically limit the type and quantity of information included in the second information.

[0061] It should be noted that, in the embodiments of this application, Figure 4 Schematic diagram of the method for supporting Metaverse services proposed in this embodiment Figure 2 ,like Figure 4 As shown, before the first network function receives the first request sent by the fifth network function, that is, before step 101, the following steps may also be included:

[0062] Step 104: The fifth network function receives a first request sent by the second UE; wherein the first UE includes at least the second UE, and the first request includes at least a metaverse service request.

[0063] It should be noted that, in the embodiment of the present application, the first UE includes one or more UEs in the area where the second UE is located.

[0064] Step 105: The fifth network function forwards the first request to the sixth network function in the IMS, and sends the first request to the first network function.

[0065] It should be noted that, in the embodiment of the present application, the sixth network function may be an S-CSCF, and the present application does not specifically limit the type of the sixth network function.

[0066] Further, in an embodiment of the present application, after receiving the first request sent by the fifth network function, the sixth network function may send the first request to the third network function if it identifies that the first request is a metaverse service request; then the third network function may send a query request to the first network function based on the first request, so that the first network function queries the third information corresponding to each first UE based on the query request.

[0067] It should be noted that in an embodiment of the present application, the third information may include a digital twin object corresponding to each first UE. The digital twin object may be an entity mapping object of the first UE in the metaverse. This application does not specifically limit the amount and type of information included in the third information.

[0068] Step 102: When the first request carries the first information, the first network function queries the third information corresponding to each first UE in the same area based on the first information; wherein the third information includes the digital twin object corresponding to each first UE.

[0069] In an embodiment of the present application, after the first network function in the IMS receives the first request sent by the fifth network function, when the first request carries the first information, the first network function queries the third information corresponding to each first UE in the same area based on the first information.

[0070] It should be noted that, in an embodiment of the present application, when the first network function queries the third information corresponding to each first UE in the same area based on the first information, it can query all UEs in the same area based on the location information of the second UE; then the first network function can query the third information corresponding to each first UE in the same area.

[0071] Exemplarily, in an embodiment of the present application, after the first network function receives a first request sent by the fifth network function, which carries the first information, and receives a query request sent by the third network function, the first network function can query all UEs in the same area based on the location information of the second UE, and then the first network function can query the digital twin object corresponding to each first UE.

[0072] For example, in an embodiment of the present application, assuming that the second UE is a mobile phone, the first network function can query all UEs in the same area based on the location information of the second UE. Assuming that there are also handles, wearable devices, etc. in the same area as the second UE, the present application does not specifically limit the type of the second UE.

[0073] Step 103: The first network function sends the third information to the third network function, so that the third network function associates each first UE with the data flow information of the corresponding digital twin object.

[0074] It should be noted that in an embodiment of the present application, after the first network function queries the third information corresponding to each first UE in the same area based on the first information, the third information can be sent to the third network function so that the third network function can associate each first UE with the data flow information of the corresponding digital twin object.

[0075] It should be noted that, in the embodiments of this application, Figure 5 Schematic diagram of the method for supporting Metaverse services proposed in this embodiment Figure 3 ,like Figure 5 As shown, after the first network function sends the third information to the third network function, that is, after step 103, the following steps may also be included:

[0076] Step 106: The third network function sends a second request to the second network function in the IMS; wherein the second request carries third information.

[0077] Step 107: The second network function sends fourth information to the third network function based on the third information; wherein the fourth information includes data flow information corresponding to each digital twin object.

[0078] It should be noted that in an embodiment of the present application, the fourth information may include data stream information corresponding to each digital twin object. The data stream information may be behavior data, action data, etc. corresponding to the digital twin object of each UE in the virtual world. Each UE can be associated with multiple data stream information. This application does not specifically limit the type of information included in the fourth information.

[0079] Step 108: The third network function generates a first policy based on the fourth information, and applies the first policy to the session of the first UE; wherein the first policy is used to associate each first UE with corresponding data flow information.

[0080] It should be noted that, in the embodiment of the present application, the first policy may be a data flow association policy, which is used to associate each first UE with corresponding data flow information.

[0081] Furthermore, in an embodiment of the present application, after applying the first policy to the session of the first UE, the third network function may send a notification message to the sixth network function; wherein the notification message includes at least the first policy; and then the sixth network function may update the initial policy in the fifth network function based on the first policy, so that the fifth network function coordinates and manages the data flow associated with the first UE based on the updated policy.

[0082] That is to say, in an embodiment of the present application, after the first network function receives the first request sent by the fifth network function, which carries the first information, and receives the query request sent by the third network function, the first network function can query all UEs in the same area based on the location information of the second UE, and then the first network function can query the third information corresponding to each first UE in the same area, that is, the digital twin object corresponding to each first UE, and then the first network function can send the third information to the third network function, and the third network function can send a second request to the second network function; wherein the second request carries the third information, and then the second network function can send the fourth information to the third network function based on the third information; wherein the fourth information includes the data flow information corresponding to each digital twin object, so that the third network function can generate a first strategy based on the fourth information, and apply the first strategy to the session of the first UE, and the first strategy is used to associate each first UE with the corresponding data flow information, thereby realizing the association of the data flow information of each first UE with the corresponding digital twin object in the mobile metaverse service scenario.

[0083] It should be noted that, in the embodiments of this application, Figure 6 Schematic diagram of the method for supporting Metaverse services proposed in this embodiment Figure 4 ,like Figure 6 As shown, after the first network function receives the first request sent by the fifth network function, that is, after step 101, the first network function may further include the following steps:

[0084] Step 109: When the first request carries the second information, the first network function may analyze and process the updated location information, determine the metaverse service related to the updated location information, and send the metaverse service to the third network function.

[0085] Exemplarily, in an embodiment of the present application, assuming that the second information includes the updated location information of the second UE, the first network function can analyze and process the updated location information of the second UE, thereby determining the metaverse service related to the updated location information of the second UE.

[0086] Step 110: The third network function sends a third request to the second network function; wherein the third request carries the Metaverse service.

[0087] Step 111: The second network function obtains fifth information corresponding to the metaverse service, and identifies sixth information corresponding to one or more third UEs based on the fifth information, where the fifth information includes metaverse service information, the metaverse service information includes at least metaverse service scenario information, the sixth information includes at least multimedia content to be coordinated, and the third UE includes at least the second UE.

[0088] It should be noted that, in the embodiment of the present application, the third UE includes all UEs in the same area as the updated second UE, and the present application does not specifically limit the number and type of UEs included in the third UE.

[0089] It should be noted that in the embodiments of the present application, the fifth information includes metaverse service information, and the metaverse service information at least includes metaverse service scene information, such as the topography and character relationships in the game scene. The type of information included in the fifth information of the present application is not specifically limited.

[0090] Furthermore, in an embodiment of the present application, after the second network function obtains the fifth information corresponding to the metaverse service and identifies the sixth information corresponding to one or more third UEs based on the fifth information, the sixth information can be sent to the fourth network function; then the fourth network function can generate a media coordination strategy based on the sixth information; wherein the media coordination strategy includes at least timing information of the media streams corresponding to one or more third UEs, and / or spatial relationship information; and then the fourth network function can send the media coordination strategy to the second network function; the second network function determines the corresponding coordinated multimedia content based on the media coordination strategy, and sends the media coordination strategy and the coordinated multimedia content to the third network function.

[0091] It should be noted that in the embodiments of the present application, the media coordination strategy includes at least timing information of the media streams corresponding to one or more third UEs, and / or spatial relationship information. For example, different third UEs may correspond to different media streams, and these media streams will have corresponding timing, spatial relationships, etc. The present application does not specifically limit the number of media streams corresponding to the third UE.

[0092] That is, in an embodiment of the present application, when the first request carries the second information, the first network function can analyze and process the updated location information, determine the metaverse service related to the updated location information, and send the metaverse service to the third network function, and then the third network function can send a third request to the second network function; wherein the third request carries the metaverse service, and then the second network function can obtain the fifth information corresponding to the metaverse service, and after identifying the sixth information corresponding to one or more third UEs based on the fifth information, the sixth information can be sent to the fourth network function; then the fourth network function can generate a media coordination policy based on the sixth information; wherein the media coordination policy includes at least timing information and / or spatial relationship information of the media streams corresponding to one or more third UEs; and then the fourth network function can send the media coordination policy to the second network function; so that the second network function can determine the corresponding coordinated multimedia content based on the media coordination policy, and send the media coordination policy and the coordinated multimedia content to the third network function, that is, the IMS proposed in the embodiment of the present application can coordinate multiple mobile metaverse services related to physical locations and realize intelligent coordination of multimedia content, thereby providing users with a localized service experience.

[0093] Furthermore, in an embodiment of the present application, after receiving the media coordination policy and the coordinated multimedia content sent by the second network function, the third network function can generate a session policy and send the session policy to the sixth network function; wherein the session policy includes the media coordination policy and the coordinated multimedia content; then the sixth network function can update the initial policy in the fifth network function based on the media coordination policy, so that the fifth network function manages and transmits the coordinated multimedia content based on the updated policy.

[0094] To sum up, after receiving the first request sent by the fifth network function, the first network function can determine whether the first request carries the first information or the second information. If the first request carries the first information, the first network function can query the third information corresponding to each first UE in the same area, that is, the digital twin object corresponding to each first UE, and then the first network function can send the third information to the third network function, and the third network function can send a second request to the second network function; wherein, the second request carries the third information, and then the second network function can send the fourth information to the third network function based on the third information; wherein, the fourth information includes the data flow information corresponding to each digital twin object, so that the third network function can generate a first strategy based on the fourth information, and apply the first strategy to the session of the first UE. The first strategy is used to associate each first UE with the corresponding data flow information, thereby realizing the association of the data flow information of each first UE with the corresponding digital twin object in the mobile metaverse service scenario. When the first request carries the second information, the first network function can analyze and process the updated location information, determine the metaverse service related to the updated location information, and send the metaverse service to the third network function, and then the third network function can send a third request to the second network function; wherein the third request carries the metaverse service, and then the second network function can obtain the fifth information corresponding to the metaverse service, and after identifying the sixth information corresponding to one or more third UEs based on the fifth information, the sixth information can be sent to the fourth network function; then the fourth network function can generate a media coordination strategy based on the sixth information; wherein the media coordination strategy includes at least timing information of the media streams corresponding to one or more third UEs, and / or spatial relationship information; and then the fourth network function can send the media coordination strategy to the second network function; so that the second network function can determine the corresponding coordinated multimedia content based on the media coordination strategy, and send the media coordination strategy and the coordinated multimedia content to the third network function, that is, the IMS proposed in the embodiment of the present application can coordinate multiple mobile metaverse services related to physical locations, and realize intelligent coordination of multimedia content, thereby providing users with a localized service experience.

[0095] The embodiment of the present application provides a method for supporting metaverse services, which is applied to IMS, and the method includes: a first network function in the IMS receives a first request sent by a fifth network function in the IMS; wherein the first request carries first information or second information; when the first request carries the first information, the first network function queries the third information corresponding to each first UE in the same area based on the first information; wherein the third information includes the digital twin object corresponding to each first UE; the first network function sends the third information to the third network function in the IMS, so that the third network function associates each first UE with the data flow information of the corresponding digital twin object. It can be seen that after the first network function in the IMS receives the first request sent by the fifth network function, if the first request carries the first information, it can query the third information corresponding to each first UE in the same area based on the first information, that is, the digital twin object corresponding to each first UE, and then send the third information to the third network function, so that the third network function can associate each first UE with the data flow information of the corresponding digital twin object, that is, the embodiment of the present application can add different network functions in the IMS, and associate multiple UEs with the data flow information of the corresponding digital twin object through the interaction process between different network functions, thereby achieving direct support for mobile metaverse services.

[0100] It should be noted that, in an embodiment of the present application, the key process of the IMS system for associating and coordinating data flows associated with one or more UEs may include: UE initiates a request → P-CSCF (ie, the fifth network function) forwards → S-CSCF (ie, the sixth network function) routes to SCS (ie, the third network function), and then SCS queries LAS (ie, the first network function) to obtain location-related information, SCS interacts with MAS (ie, the second network function) to obtain data flow information, and then SCS can generate an association policy and apply it to the relevant session.

[0101] Furthermore, in the embodiments of the present application, Figure 8 A flow chart of associating one or more UE-related data flows proposed in an embodiment of the present application is shown as follows: Figure 8As shown, the process of associating one or more UE-related data flows may include the following steps: 1. The UE (i.e., the second UE) initiates a metaverse service request (i.e., the first request) to the IMS network through the P-CSCF (i.e., the fifth network function), which includes the UE's location information (i.e., the first information); 2. The P-CSCF (i.e., the fifth network function) forwards the request to the S-CSCF (i.e., the sixth network function), and at the same time sends the UE's location information to the LAS (i.e., the first network function); 3. The S-CSCF (i.e., the sixth network function) identifies it as a metaverse service request and routes it to the SCS (i.e., the third network function); 4. After receiving the request, the SCS (i.e., the third network function) queries the LAS for related UE and object information (i.e., digital twin object); 5. The LAS (i.e., the first network function) returns the same location information based on the received location information (i.e., the first information). Relevant UE (i.e., the first UE) and digital twin object information (i.e., the third information) within a region; 6. SCS (i.e., the third network function) communicates the acquired information (i.e., the third information) with MAS (i.e., the second network function) to request relevant data flow information; 7. MAS (i.e., the second network function) returns the data flow information (i.e., the fourth information) of the relevant objects in the digital twin application; 8. SCS (i.e., the third network function) generates a data flow association policy (i.e., the first policy) based on the received information, and applies it to the relevant UE session; 9. SCS (i.e., the third network function) notifies S-CSCF (i.e., the sixth network function) to update the session information, and S-CSCF updates the policy in P-CSCF (i.e., the fifth network function) accordingly; 10. P-CSCF (i.e., the fifth network function) coordinates and manages the data flow of the relevant UE according to the updated policy.

[0102] For example, in an embodiment of the present application, assuming that the second UE is a mobile phone, the first network function can query all UEs in the same area based on the location information of the second UE. Assuming that there are also handles, wearable devices, etc. in the same area as the second UE, the present application does not specifically limit the type of the second UE.

[0103] It should be noted that in an embodiment of the present application, the third information may include a digital twin object corresponding to each first UE. The digital twin object may be an entity mapping object of the first UE in the metaverse. This application does not specifically limit the amount and type of information included in the third information.

[0104] That is to say, in an embodiment of the present application, after the first network function receives the first request sent by the fifth network function, which carries the first information, and receives the query request sent by the third network function, the first network function can query all UEs in the same area based on the location information of the second UE, and then the first network function can query the third information corresponding to each first UE in the same area, that is, the digital twin object corresponding to each first UE, and then the first network function can send the third information to the third network function, and the third network function can send a second request to the second network function; wherein the second request carries the third information, and then the second network function can send the fourth information to the third network function based on the third information; wherein the fourth information includes the data flow information corresponding to each digital twin object, so that the third network function can generate a first strategy based on the fourth information, and apply the first strategy to the session of the first UE, and the first strategy is used to associate each first UE with the corresponding data flow information, thereby realizing the association of the data flow information of each first UE with the corresponding digital twin object in the mobile metaverse service scenario.

[0105] It should be noted that, in an embodiment of the present application, the key process of the IMS system for multimedia content coordination may include: UE location update → LAS (ie, the first network function) analyzes and notifies SCS (ie, the third network function); SCS (ie, the third network function) requests MAS (ie, the second network function) to obtain service information (ie, metaverse service information); MAS (ie, the second network function) notifies MCS (ie, the fourth network function) to perform media coordination; MCS (ie, the fourth network function) generates a coordination plan (ie, media coordination strategy) and returns it to MAS (ie, the second network function); SCS (ie, the third network function) generates a comprehensive session strategy; P-CSCF (ie, the fifth network function) manages and transmits the coordinated content to the UE.

[0106] Furthermore, in the embodiments of the present application, Figure 9 This is a flow chart of multimedia content coordination performed by the IMS system proposed in the embodiment of the present application, as shown in FIG. Figure 9As shown, the process of multimedia content coordination in the IMS system may include the following steps: 1. UE sends a location update request to the IMS network through the P-CSCF (i.e., the fifth network function); 2. The P-CSCF (i.e., the fifth network function) forwards the location information (i.e., the second information) to the LAS (i.e., the first network function); 3. The LAS (i.e., the first network function) analyzes the location information, determines the relevant localized metaverse service, and notifies the SCS (i.e., the third network function); 4. The SCS (i.e., the third network function) requests the MAS (i.e., the second network function) to obtain the relevant metaverse service information (i.e., the fifth information); 5. The MAS (i.e., the second network function) identifies the multimedia content that needs to be coordinated (i.e., the sixth information) and notifies the MCS (i.e., the fourth network function); 6. The MCS generates a media coordination plan ( 7. MCS (i.e., the fourth network function) sends the coordination plan (i.e., media coordination policy) to MAS (i.e., the second network function); 8. MAS prepares the corresponding media content (i.e., the coordinated multimedia content) according to the coordination plan (i.e., media coordination policy) and notifies SCS (i.e., the third network function); 9. SCS (i.e., the third network function) generates a comprehensive session strategy, including media coordination information (i.e., media coordination policy), and sends it to S-CSCF (i.e., the sixth network function); 10. S-CSCF (i.e., the sixth network function) updates the strategy in P-CSCF (i.e., the fifth network function); 11. P-CSCF (i.e., the fifth network function) manages and transmits the coordinated multimedia content to UE according to the updated strategy.

[0107] That is, in an embodiment of the present application, when the first request carries the second information, the first network function can analyze and process the updated location information, determine the metaverse service related to the updated location information, and send the metaverse service to the third network function, and then the third network function can send a third request to the second network function; wherein the third request carries the metaverse service, and then the second network function can obtain the fifth information corresponding to the metaverse service, and after identifying the sixth information corresponding to one or more third UEs based on the fifth information, the sixth information can be sent to the fourth network function; then the fourth network function can generate a media coordination policy based on the sixth information; wherein the media coordination policy includes at least timing information and / or spatial relationship information of the media streams corresponding to one or more third UEs; and then the fourth network function can send the media coordination policy to the second network function; so that the second network function can determine the corresponding coordinated multimedia content based on the media coordination policy, and send the media coordination policy and the coordinated multimedia content to the third network function, that is, the IMS system proposed in the embodiment of the present application can coordinate multiple mobile metaverse services related to physical locations and realize intelligent coordination of multimedia content, thereby providing users with a localized service experience.

[0108] To sum up, after receiving the first request sent by the fifth network function, the first network function can determine whether the first request carries the first information or the second information. If the first request carries the first information, the first network function can query the third information corresponding to each first UE in the same area, that is, the digital twin object corresponding to each first UE, and then the first network function can send the third information to the third network function, and the third network function can send a second request to the second network function; wherein, the second request carries the third information, and then the second network function can send the fourth information to the third network function based on the third information; wherein, the fourth information includes the data flow information corresponding to each digital twin object, so that the third network function can generate a first strategy based on the fourth information, and apply the first strategy to the session of the first UE. The first strategy is used to associate each first UE with the corresponding data flow information, thereby realizing the association of the data flow information of each first UE with the corresponding digital twin object in the mobile metaverse service scenario. When the first request carries the second information, the first network function can analyze and process the updated location information, determine the metaverse service related to the updated location information, and send the metaverse service to the third network function, and then the third network function can send a third request to the second network function; wherein the third request carries the metaverse service, and then the second network function can obtain the fifth information corresponding to the metaverse service, and after identifying the sixth information corresponding to one or more third UEs based on the fifth information, the sixth information can be sent to the fourth network function; then the fourth network function can generate a media coordination strategy based on the sixth information; wherein the media coordination strategy includes at least timing information of the media streams corresponding to one or more third UEs, and / or spatial relationship information; and then the fourth network function can send the media coordination strategy to the second network function; so that the second network function can determine the corresponding coordinated multimedia content based on the media coordination strategy, and send the media coordination strategy and the coordinated multimedia content to the third network function, that is, the IMS system proposed in the embodiment of the present application can coordinate multiple mobile metaverse services related to physical locations, and realize intelligent coordination of multimedia content, thereby providing users with a localized service experience.

It can be seen that after the first network function in the IMS receives the first request sent by the fifth network function, if the first request carries the first information, it can query the third information corresponding to each first UE in the same area based on the first information, that is, the digital twin object corresponding to each first UE, and then send the third information to the third network function, so that the third network function can associate each first UE with the data flow information of the corresponding digital twin object, that is, the embodiment of the present application can add different network functions in the IMS, and associate multiple UEs with the data flow information of the corresponding digital twin object through the interaction process between different network functions, thereby achieving direct support for mobile metaverse services.
