Referring to fig. 2, an embodiment of the present application provides a multicast service processing method, including:

In the embodiment of the application, the first indication information can be AF information of the target AF, the second network function can be a multicast session management function (Multicast and Broadcast-Session Management Function), the first network function sends the AF information to the MB-SMF and acquires the related information of the access terminal from the MB-SMF, and the related information of the access terminal is used for sending multicast broadcast data to the access terminal indicated by the related information of the access terminal by the AF indicated by the AF information, thereby realizing the triggering of a multicast service data transmission channel by a network side.

The first network function may be a NEF or the first network function may be a multicast service function (Multicast and Broadcast Service Function, MBSF).

The AF information may specifically be an AF ID;

in the above step 202, optionally, the target AF may send the AF information to the first network function by sending a message carrying the AF information, for example, the AF may send a create request message (for example MBS area create request), or an update request message (for example MBS area update request), or a delete request message (for example MBS area delete request) to the first network function, where the AF ID is carried. The embodiment of the application does not limit the type of the information carrying AF information.

Alternatively, the first network function may authorize the AF indicated by the AF information after receiving the AF information.

In the step 202, the first network function sends the AF information to the MB-SMF to obtain the related information of the access terminal, so that based on the related information of the access terminal, the AF indicated by the AF information sends multicast broadcast data to the access terminal indicated by the related information of the access terminal, that is, establishes a data transmission channel between the target AF and the access terminal. After the data transmission channel is established, the channel can be directly used when multicast broadcast service data is subsequently provided, and one AF can provide a plurality of multicast broadcast services, so that the multicast broadcast services can directly use the tunnel to send data, and the channel is not established for the multicast broadcast services only when certain multicast broadcast service data needs to be provided according to the prior art, and different tunnels are established for different multicast broadcast services, namely the relevance between the multicast service data transmission channel and the multicast service of the terminal is relieved.

The technical scheme of the application is described below with reference to specific implementation examples:

Example one: referring to FIG. 5a, the overall procedure for AF-triggered MBS session management is shown, comprising the following steps:

the ue has established an associated PDU session for the MBS. During the PDU session establishment procedure, the UE indicates MBS capabilities to the SMF.

1. When the AF needs to send MBS data using a tunnel, the AF manages a tunnel between the AF and the 5GC, which is not for each MBS session. This step may be performed before step 2 or after step 2.

2. The content provider may use portal publishing services that may be dynamically published, e.g., real-time streaming scheduled by real-time streaming media, real-time interviews of breaking news, etc. The user may access the portal through an application in the UE and request the contents of the MBS service, which may be an interactive MBS service, i.e., including multicast service data and unicast service data.

AF interacts with 5GC to manage MBS AF sessions for UE.

4.5GC manages MBS UE sessions towards the UE.

Example two: referring to fig. 5b, there is shown an MBS 5GC-AF connection management procedure comprising the following procedures:

it should be noted that an optional procedure, the MB-UPF/MBSTF entry address may be preconfigured for one or more AFs.

1. In order to create a 5GC-AF connection for MBS service, AF sends an MBS AF connection creation request (AF ID, [ zone information ]) to NEF/MBSF. In order to update the 5GC-AF connection of the MBS service, the AF sends an MBS AF connection update request (AF ID, zone information) to the NEF/MBSF. In order to delete the 5GC-AF connection of the MBS service, the AF sends an MBS AF connection delete request (AF ID) to the NEF/MBSF.

If the AF is only providing service in a limited area, it may include area information, which may be a set of geographical location information, or city street address information, or cell information, or tracking area information, or area location identification, etc.

NEF/MBSF authorizes AF.

3. If the authorization is successful, NEF/MBSF first discovers MB-SMF from NRF by providing AF ID, NRF selects MB SMF configured for AF, and responds with MB SMF information. For creation, if no MB-SMF is found, then the NEF/MBSF then finds the MB-SMF through the region information, receives the region information from step 1, or locally configures for the AF. For updating, if the returned MB-SMF cannot cover the area information, the NEF/MBSF then discovers the MB-SMF with the appropriate area information. The NRF selects an appropriate MB SMF according to the region information and responds with the information of the MB SMF.

4. For creation and update, if necessary, the NEF/MBSF selects MB SMF according to the zone information, and invokes MBS AF connection creation request (AF ID, [ zone information ]) or MBS AF connection update request (AF ID, zone information) to MB SMF. For deletion, NEF/MBSF invokes MBS AF-connection delete request (AF ID) to MB SMFs. The area information may be a set of cell information, or tracking area information, or area location identification, etc.

5. For creation and update, if MB-SMF has not registered AF ID to NRF, MB-SMF registers AF ID to NRF. For deletion, MB-SMF deregisters AF ID from NRF.

For creation, the MB-SMF selects the MB-UPF based on the received region information (if received), and may interact with the MB-UPF to create the entry address for the AF. For the update, the MB-SMF selects the MB-UPF that does not service the AF and may interact with the MB-UPF to create the entry address for the AF. For deletion, the MB-SMF may interact with the MB-UPF serving the AF to release the connection resources.

The MB-SMF responds to the NEF/MBSF, and upon creation and update, the MB-SMF sends an entry address and corresponding region information to the NEF.

For creation and updating, if the MBSF decision involves an MBSTF, the MBSF will interact with the MBSTF using the received entry address, and the MBSTF will return the entry address of the MBSTF. For deletion, if the MBSTF participates in creation, the MBSF will interact with the MBSTF to release the connection resources.

NEF/MBSF response AF. For creation and updating, the NEF/MBSF sends the entry address and optionally the corresponding region information to the AF. The AF uses the area information to determine which entry address to use for transmitting MBS data based on the UE location.
