[0047] 5G New Call is a new real-time communication service that integrates high-definition audio and video calls with data applications, built upon 5G VoNR's multimedia real-time communication.

[0048] Based on the current IP Multimedia Subsystem (IMS) architecture enhancement, a service-oriented interface has been introduced, enabling it to support interactive communication and augmented reality (AR) communication services at the present stage, while also possessing scalability to support innovative services brought about by the introduction of more new media technologies in the future.

[0049] like Figure 2 The diagram shows the process for establishing the NG-RTC data channel in R18, including:

[0050] 1. The UE sends a data channel service request (or data channel establishment request, such as a Session Initialization Protocol reInvite (SIP reinvite) request). This data channel service request carries an updated Session Description Protocol (updated SDP), which includes bootstrap data channel information, the requested application data channel (App DC), and the corresponding data channel application binding (DC App binding) message.

[0051] 2. The IMS Application Server (AS) verifies the UE's subscription information and decides whether to inform the Data Channel Signaling Function (DCSF) of the request;

[0052] 3. IMS AS notifies DCSF of the request through the Nimsas_SessionEventControl_Notify service;

[0053] 4. DCSF decides whether to provide a DC based on application binding information;

[0054] 5. DCSF decided to establish an App DC for the Session Description Protocol offer (SDP offer), and to target the Data Channel Application Server (DCAS) and use the Management Function (MF) as the media service anchor.

[0055] 6. DCSF informs IMS AS through the Nimsas_MediaControl service to terminate the media stream of the source UE at MF, and at the same time informs the media data of the data channel to be forwarded through the Multitenant DeviceContext (MDC) Layer 2 (i.e. MDC2).

[0056] 7. IMS AS calls the Nmf_MRM_Create service to reserve media resources;

[0057] 8. IMS AS responds to DCSF;

[0058] 9. DCSF stores media resource information and sends a Person to Application (P2A) connection establishment request to DCAS, carrying MDC2 SDP;

[0059] 10. DCAS accepts the request and returns a response (MDC2 SDP Offer; details on how DCSF communicates with the DC application server are beyond the scope of this version's discussion).

[0060] 11. The DCSP requests the IMS AS to update the MF resource with MDC2 information.

[0061] 12. IMS AS update;

[0062] 13. IMS AS sends an update response;

[0063] 14. DCSF returns a session event control response;

[0064] 15-16. IMS AS sends a re-invite request to UE2 regarding the audio / video / bootstrap data channel;

[0065] 17-19: UE2 and the terminating network end return a 200 OK response (i.e., the modification session request was successfully received).

[0066] 20. IMS AS notified DCSF that the Media Change Event was successful;

[0067] 21-27: Related response return and application data channel activation.

[0068] For DC applications, it is foreseeable that some media processing will have computing power-related business requirements. However, based on the aforementioned data channel establishment process, it is clear that the current data channel establishment only considers business capabilities (i.e., the current NG-RTC only considers how the data channel is established), without considering whether DCAS has sufficient computing power or network processing capabilities to complete the data channel's business (e.g., computing power tasks or media tasks initiated by user equipment). For example, the design of SDP offers does not quantitatively consider the resource capability requirements of media stream processing for DCAS, making it impossible to efficiently and finely differentiate the resource capability requirements of data channel services for relevant network elements. Furthermore, the interaction between DCSF and DCAS is not detailed, and no detailed business process design has been implemented for the relevant interactions.

[0069] Based on the above analysis, the following two points are currently not considered in the data channel establishment process:

[0070] 1. Can DCAS support the UE's requirements for processing different types of media?

[0071] 2. If DCAS (or AR AS for AR services) performs service rendering, the network cannot manage its available resources because IMS does not support the underlying resource negotiation or load capacity negotiation.

[0072] To address the problems existing in related technologies, this application provides a method, apparatus, device, and medium for establishing a data channel and a P2A connection. Based on the NG-RTC data channel establishment method in related technologies, the processing capabilities of network application servers, such as computing power information and load processing capabilities, are considered in the establishment process of real-time communication services to ensure sufficient resource support for real-time communication services with extremely high application processing capabilities.

[0073] For ease of description, the following unified explanation of the various terms involved in the embodiments of this application is provided first. (Unless otherwise specified, the following unified explanation of the various terms applies to the various implementations of this application. Since some terms appear later in the text, they will not be uniformly explained here, but will be explained when they first appear in the following text):

[0074] The first network element: This is a node that requests computing power and can be a network element with computing power resource processing capabilities. For example, the first network element can be a DCSF, but is not limited to DCSF.

[0075] The second network element is a computing power application server or computing power node, which can be a related network element capable of providing computing power resources. For example, the second network element can be a DCAS (or AF, Application Specific Device, Asd) but is not limited to DCAS.

[0076] The third network element is a relay node for information exchange between the first and second network elements. For example, the third network element can be a NEF, but is not limited to NEF.

[0077] Target network element: This is a relay node for information exchange between the network layer and the application layer, and can be a relevant network element with gateway forwarding capabilities. For example, the target network element can be a Data Channel Media Function (DCMF, also known as MF, MRF, or UPF), but is not limited to DCMF.

[0078] User equipment: may be Figure 1 Terminal 11 in the example is provided above and will not be repeated here.

[0079] The first request, carrying resource requirement information, is sent by network elements such as the IMS AS to the first network element. This first request is a request to establish a data channel DC between the user equipment (UE) and the target network element. For example, the first request may be a session event control request that has added resource requirement information to the included media info list.

[0080] like Figure 3 As shown, taking the session event control request as a media modification request (Nimsas_SessionEventControl_Notify) as an example, the media information list of this media modification request includes the Media ID, Media Specification (including Media type, Data Channel Mapping and Configuration Information during DC establishment, Maximum Message Size, Data Channel Port, and Security technologies and protocols), etc. After the IMS AS adds the resource requirement information sent by the UE to this media information list, it sends the media modification request carrying the resource requirement information to the first network element, so that the first network element can continue to execute the data channel establishment process such as P2A connection establishment based on the resource requirement information.

[0081] Resource requirement information: used to characterize at least one of the following: computing resources, load information, and network resources required for a computing or media task initiated by the UE.

[0082] The resource requirement information may include at least one of the following:

[0083] Computing resource requirement information is used to indicate the amount of computing power required for data processing, such as memory size or processor size.

[0084] Load information is used to indicate the type of data processing. For example, the load information can indicate the rendering type, the artificial intelligence (AI) computing type, or the computing power type such as the computing power of the central processing unit (CPU), the computing power of the graphics processing unit (GPU), or the computing power of the field programmable gate array (FPGA).

[0085] Network resource demand information is used to indicate the amount of network processing capacity required for data processing. For example, this network resource demand information can indicate information such as integer or floating-point calculation rates.

[0086] The second request is sent from the first network element to the second network element. This second request is used to request the second network element to reserve or apply for at least one of the following: computing resources, load information, and network resources required for a computing or media task initiated by the UE.

[0087] The third request, carrying resource requirement information, is sent by the UE to network elements such as the IMS AS. This third request is used to request the establishment of a data channel (DC) between the UE and the target network element, and to request the second network element to reserve or apply for at least one of the following: computing resources, load information, and network resources required for a computing or media task initiated by the UE. For example, this third request can be a SIP reInvite request, which carries the aforementioned updated SDP. If the updated SDP contains bootstrap DC information, the requested App DC, and the corresponding DC APP binding message, the UE can add resource requirement information to the updated SDP to send an SIPreInvite request with the added resource requirement information to the IMS AS.

[0088] Based on the above unified explanation of various terms, the first aspect of the embodiments of this application provides a method for establishing a data channel, which is executed by a first network element, see [link to relevant documentation]. Figure 4 The diagram shown is an implementation flowchart of a data channel establishment method provided in this application embodiment. The method may include the following steps:

[0089] Step S101: The first network element receives a first request, which is used to request the establishment of a data channel DC between the user equipment (UE) and the target network element. The first request carries resource requirement information, which is used to characterize at least one of computing power resources, load information and network resources required to serve the computing power task or media task initiated by the UE.

[0090] Among them, media tasks refer to the overall processing tasks of the media stream transmitted by the data channel, while computing power tasks refer to computing tasks such as image rendering within the processing tasks of the media stream transmitted by the data channel.

[0091] In practical implementation, after receiving the first request, the first network element can know, based on the resource requirement information carried in the first request, whether the UE has initiated a computing power task or a media task, and at least one of the computing power resources, load information, and network resources required. This allows for efficient and fine-grained differentiation of data channel services. When executing the data channel establishment process corresponding to the first request (such as starting to establish a P2A connection), for computing power tasks or media tasks with computing power-related resource requirements, the first network element can apply for and reserve computing power-related resources for the computing power task or media task (or in advance), or inform the second network element of the resource requirement information. The second network element can then decide whether to continue executing the data channel establishment process based on the computing power-related resources it can provide. This ensures that for each established data channel, there are sufficient resources to support the processing of the data channel's services.

[0092] As can be seen from the above steps, by transmitting the resource requirement information of user equipment, the relevant network elements can know the computing resources, load information, or network resource computing power related service requirements required to serve the computing power task or media task initiated by the user equipment during the data channel establishment process. This enables efficient and fine-grained differentiation of data channel services and ensures that there are sufficient resources to support the processing of data channel services after the data channel establishment process is completed.

[0093] Implementation Method 1

[0094] This implementation describes an example of a first network element requesting or reserving computing power-related resources from a second network element during the P2A connection establishment process.

[0095] During the P2A connection establishment process, the first network element sends a second request (the second request is a P2A connection establishment request) to the second network element, requesting the second network element to reserve sufficient resources in advance from at least one of the computing power resources, load information and network resources that it can provide to support the processing of the computing power task or media task, or requesting the second network element to increase at least one of the computing power resources, load information and network resources that it can provide in a timely manner based on the resources it can provide (such as requesting to add computing power nodes managed by itself), so as to ensure that the second network element can provide sufficient resources to support the processing of the computing power task or media task.

[0096] As one possible implementation, the first network element sends a second request to the second network element, including:

[0097] The first network element sends a connection establishment request carrying the resource demand information to the second network element;

[0098] The connection establishment request carrying the resource requirement information is used to: request the establishment of a P2A connection, and request the second network element to reserve or apply for at least one of the computing resources, load information and network resources required for the computing power task or media task initiated by the UE.

[0099] In this embodiment, the first network element sends a connection establishment request carrying the resource demand information to the second network element, so as to request the application or reservation of computing power related resources at the same time as requesting the establishment of a P2A connection, thereby reducing the number of interactions between the first network element and the second network element.

[0100] Implementation Method 2

[0101] This embodiment describes an example of a first network element requesting or reserving computing power-related resources from a second network element before a P2A connection is established.

[0102] Before the P2A connection is established, the first network element sends a second request (which is a resource reservation request or a resource application request) to the second network element to request the second network element to reserve or apply for at least one of the computing resources, load information and network resources required for the computing power task or media task initiated by the UE.

[0103] As one possible implementation, the first network element sends a second request to the second network element, including:

[0104] The first network element sends a resource reservation request or a resource application request to the second network element. The resource reservation request or resource application request is used to request the second network element to reserve or apply for at least one of the computing resources, load information and network resources required for the computing power task or media task initiated by the UE.

[0105] In this embodiment, before establishing a P2A connection (e.g., sending a connection establishment request), the first network element sends a resource reservation request or resource application request to the second network element, requesting the second network element to reserve or apply for relevant resources in advance before the P2A connection is established. For example, the computing power application server, which is the second network element, can verify earlier whether it can provide sufficient resources and reserve resources if sufficient resources are available to trigger the establishment of the P2A connection. Alternatively, the computing power node, which is the second network element, can apply for resources from the computing power application server in advance. The computing power application server then increases the number of computing power nodes or terminates the data channel establishment process according to the available resources. Thus, based on the computing power resources that the second network element can provide, a decision can be made on whether to continue the data channel establishment process before the P2A connection is established, and the data channel establishment process can be terminated earlier if resources are insufficient.

[0106] Implementation Method 3

[0107] This implementation describes an example of a response to a second request.

[0108] Before reserving or requesting at least one of the computing power resources, load information, and network resources required for the computing power task or media task initiated by the UE according to the second request, the second network element will first check whether it can provide at least one of the computing power resources, load information, and network resources required for the computing power task or media task initiated by the UE, and respond in the following two ways.

[0109] Case 1: The second network element is able to provide at least one of the following: computing resources, load information, and network resources required for the computing or media tasks initiated by the UE.

[0110] In this embodiment, the second network element sends a resource reservation success response or a resource application success response to indicate that the second network element has reserved or applied for at least one of the computing resources, load information and network resources required for the computing power task or media task initiated by the UE.

[0111] It is understandable that, for the first network element in Implementation Method 2, after receiving the resource reservation success response or resource application success response sent by the second network element, the first network element can continue to execute the data channel establishment process.

[0112] For example, after receiving a resource reservation success response or a resource application success response sent by the second network element, the first network element will send a connection establishment request to the second network element to request the establishment of a P2A connection, or store resource information. The resource information includes: information of the second network element and information of at least one of computing resources, load information and network resources reserved by the second network element for computing power tasks or media tasks initiated by the UE.

[0113] Scenario 2: The second network element cannot provide at least one of the computing resources, load information, and network resources required for the computing power task or media task initiated by the UE.

[0114] In this embodiment, the second network element will send a resource reservation failure response or a resource application failure response. After receiving the resource reservation failure response or the resource application failure response sent by the second network element, the first network element will terminate the DC establishment process between the UE and the target network element.

[0115] As one possible implementation, after receiving a second request such as a resource reservation request or a resource application request, the second network element will initiate a check on the available computing power-related resources (the check is performed by a node with computing power resource management capabilities). If the check finds that the second network element cannot provide at least one of the computing power resources, load information, and network resources required to provide the computing power task or media task initiated by the UE, if the second request is a resource reservation request, the second network element can directly send a resource reservation failure response to the first network element; if the second request is a resource application request, the second network element can apply to increase the computing power-related resources (at this time, the second network element can also skip the first check and directly apply to increase the computing power-related resources).

[0116] After applying for additional computing power resources, the second network element can check again the computing power resources it can provide (or check whether it has received a successful response to the resource increase application). If the second network element still cannot provide at least one of the computing power resources, load information, and network resources required to provide the computing power task or media task initiated by the UE (or has not received a successful response to the resource increase application), the second network element sends a resource application failure response to the first network element. If the second network element can provide at least one of the computing power resources, load information, and network resources required to provide the computing power task or media task initiated by the UE, the second network element can send a resource application success response to the first network element.

[0117] In the third implementation method, the second network element can have computing power processing capabilities to complete the inspection, application or reservation of computing power related resources. The first network element only has the ability to apply for computing power related resources and does not manage computing power related resources, so that the computing power management node is still outside the network (such as in DCAS), which is more in line with the communication architecture in related technologies.

[0118] Implementation Method 4

[0119] This implementation describes an example of interaction between a first network element and a second network element.

[0120] Considering that the relevant technologies do not record in detail the interaction process between the first network element and the second network element during the data channel establishment process, in order to realize the transmission of requests such as second requests (such as connection establishment requests, resource reservation requests, resource application requests) and their response information (such as MDC2 SDP Offer) between the first network element and the second network element, this application provides the following two business process designs between the first network element and the second network element.

[0121] Scenario 1: The first network element interacts directly with the second network element.

[0122] In scenario 1, the first network element and the second network element are directly connected. For example... Figure 3 and Figure 6 As shown, taking the first network element as DCSF and the second network element as DCAS as an example, DCSF can send the second request carrying resource demand information (such as resource reservation or application request, connection establishment request) directly to DCAS through the DC4 interface. DCAS can also send the response to the second request (such as the success or failure response of resource reservation or application, the success or failure response of connection establishment) directly to DCSF through the DC4 interface.

[0123] Scenario 2: The first network element interacts with the second network element through the third network element.

[0124] In scenario 2, a third network element connects the first network element and the second network element. For example... Figure 5 and Figure 7 As shown, taking DCSF as the first network element, DCAS as the second network element, and NEF as the third network element as an example, DCSF can call NEF's Nnef_ResourceReserve_request or Nnef_EventExposure_request services through the DC3 interface to send the second request carrying resource demand information to NEF.

[0125] Specifically, after receiving the second request carrying resource requirement information, NEF can call DCAS's N_dcas_ResourceReserve_request, N_dcas_EventExposure_request (or Naf_ResourceReserve_request, Naf_EventExposure_request) services through the N33 interface to inform DCAS of the resource requirement information carried in the second request, so as to request the reservation or application of relevant resources.

[0126] DCAS can also use the N33 interface to call NEF's Nnef_ResourceReserve_response or Nnef_EventExposure_response services to send the response to the second request or other requests to NEF.

[0127] After receiving a response to a relevant request, NEF can call services such as N_dcas_ResourceReserve_response or N_dcas_EventExposure_response from DCAS through the DC3 interface to inform DCSF of the response to the relevant request, so that DCSF can continue or terminate the execution of the data channel establishment process based on the received response.

[0128] Secondly, such as Figure 8 As shown in the embodiment of this application, another method for establishing a data channel is provided. This method is executed by a user equipment (UE) and includes at least the following steps:

[0129] Step S201: The User Equipment (UE) sends a third request carrying the resource requirement information of the UE. The resource requirement information is used to characterize at least one of the computing power resources, load information, and network resources required to serve the computing power task or media task initiated by the UE. The third request carrying the resource requirement information of the UE is used to request the establishment of a data channel DC between the UE and the target network element, and to request the second network element to reserve or apply for at least one of the computing power resources, load information, and network resources required to serve the computing power task or media task initiated by the UE.

[0130] As one possible implementation, the resource requirement information of the UE includes at least one of the following:

[0131] Computing resource demand information is used to indicate the amount of computing power required for data processing;

[0132] Load information, used to indicate the type of data processing;

[0133] Network resource demand information indicates the amount of network processing capacity required for data processing.

[0134] Thirdly, such as Figure 9 As shown, this application embodiment provides a method for establishing a P2A connection, which is executed by a second network element and includes at least the following steps:

[0135] Step S301: The second network element receives the resource requirement information sent by the first network element. The resource requirement information is used to characterize at least one of the computing power resources, load information and network resources required for the computing power task or media task initiated by the UE.

[0136] Step S302: The second network element reserves or applies for computing power resources, load information, or network resources required for the computing power task initiated by the UE, so as to trigger the establishment of P2A connection.

[0137] As one possible implementation, the second network element receives resource demand information sent by the first network element, including:

[0138] During the P2A connection establishment process, the second network element receives the resource requirement information carried in the connection establishment request sent by the first network element. The connection establishment request carrying the resource requirement information is used to: request the establishment of a P2A connection, and request the second network element to reserve or apply for at least one of computing resources, load information and network resources required for computing power tasks or media tasks initiated by the UE.

[0139] As one possible implementation, the second network element receives resource demand information sent by the first network element, including:

The resource application request is used to request the second network element to apply for at least one of the computing power resources, load information and network resources required for the computing power task or media task initiated by the UE.

[0141] In one possible implementation, the second network element is directly connected to the first network element, and the first network element directly interacts with the second network element.

[0142] In one possible implementation, a third network element is connected between the second network element and the first network element, and the second network element interacts with the first network element through the third network element.

[0143] As one possible implementation, the second network element receives resource demand information sent by the first network element, including:

[0145] As one possible implementation, before the second network element reserves or requests at least one of the computing resources, load information, and network resources required for the computing power task or media task initiated by the UE, the method further includes:

[0146] The second network element checks whether it can provide at least one of the computing resources, load information, and network resources required for the computing power task or media task initiated by the UE.

[0147] As one possible implementation, after the second network element reserves or requests at least one of the computing resources, load information, and network resources required for the computing task initiated by the UE, the method further includes:

[0148] The second network element sends a resource reservation success response or a resource application success response to the first network element.

[0149] The second network element receives a connection establishment request sent by the first network element, the connection establishment request being used to request the establishment of a P2A connection.

[0150] As one possible implementation, the method further includes:

[0151] If the second network element is unable to provide at least one of the computing power resources, load information, and network resources required for the computing power task or media task initiated by the UE, the second network element sends a resource reservation failure response or a resource application failure response to the first network element to trigger the first network element to terminate the DC establishment process between the UE and the target network element; the resource reservation failure response or the resource application failure response is used to indicate that the second network element is unable to provide at least one of the computing power resources, load information, and network resources required for the computing power task or media task initiated by the UE.
