In an embodiment, when a user of a first communication node exits a broadcast application program, the first communication node sends a PDU session release request corresponding to a target broadcast service to a second communication node, and the second communication node sends the received PDU session release request to a core network, so that the core network releases a broadcast receiving resource corresponding to the broadcast service type according to the PDU session release request, and sends the released broadcast receiving resource to the second communication node, so that the second communication node releases the broadcast receiving resource corresponding to the broadcast service type corresponding to the target broadcast service. The PDU session release request may be understood as a request for releasing broadcast receiving resources among the first communication node, the second communication node, and the core network.
In the technical scheme of this embodiment, on the basis of the above embodiment, the same broadcast service is grouped, so that the first communication node only receives broadcast service streams in service groups of the same type, thereby improving the smoothness of broadcast service playing, and after the broadcast service is finished, the corresponding broadcast receiving resource is requested to be released, so that the second communication node reallocates the broadcast receiving resource, thereby achieving the full utilization of the broadcast receiving resource.

In the actual operation process, the user may play one or more broadcast services in the broadcast application, that is, after the broadcast application in the first communication node is started, the user may switch from broadcast service 1 to broadcast service 2, then switch to broadcast service 3, then switch to broadcast service 2, and so on. It can be understood that, when a trigger operation of the user on the target broadcast service is received, the first communication node performs traversal search on the DNN list to determine whether a DNN corresponding to the target broadcast service exists in the DNN list in the first communication node. If so, execution S450 may be performed; if not, go to S430.

In the embodiment, when a DNN same as a target broadcast service does not exist in a DNN list, a first communication node sends a PDU session establishment request to a second communication node, and the second communication node sends the received PDU session establishment request to a core network, so that the core network responds to the PDU session establishment request, and feeds back PDU session response information corresponding to the PDU session establishment request to the second communication node, so that the second communication node sends the PDU session response information of the PDU session establishment request to the first communication node.
In one embodiment, sending a PDU session setup request to a second communications node comprises: generating a corresponding DNN according to the broadcast service type of the target broadcast service; and sending the PDU session establishment request carrying the DNN to a second communication node. In an embodiment, when a DNN that is the same as a target broadcast service does not exist in a DNN list stored in a first communication node, the first communication node generates a corresponding DNN according to a broadcast service type of the target broadcast service, and sends a PDU session establishment request carrying the DNN to a second communication node, so that the second communication node sends the PDU session establishment request to a core network.
And S440, receiving PDU session response information fed back by the second communication node and the distributed broadcast receiving resource matched with the target broadcast service.
In the embodiment, after the core network receives the PDU session establishment request, the PDU session establishment request is responded, and PDU session response information corresponding to the PDU session establishment request is fed back to the second communication node, after the second communication node receives the PDU session response information of the core network, a broadcast receiving resource corresponding to a broadcast service type is allocated to the first communication node, and the PDU session response information and the broadcast receiving resource are fed back to the first communication node, that is, the first communication node receives the PDU session response information fed back by the second communication node, and the second communication node allocates the broadcast receiving resource of the broadcast service type corresponding to the target broadcast service to the first communication node, so that reasonable allocation of the broadcast receiving resource is realized.

S870, receiving PDU conversation response information fed back by the network side, and receiving broadcast receiving resources distributed by the network side for the terminal side.
In the embodiment, the network side responds to the PDU Session establishment request of the terminal, establishes a PDU Session for a specific broadcast service group, and configures specific broadcast receiving resources for the terminal. The broadcast receiving resource includes but is not limited to QoS, broadcast period, broadcast scheduling resource, etc. For example, the network side can allocate a broadcast period of 10s to the standard definition broadcast CCTV1 and schedule on slot 0.
And S880, receiving and playing the broadcast information in the broadcast service group on the specific broadcast resource.
And S890, switching the broadcast service on the broadcast receiving APP, and returning to execute S850.
S8100, quitting broadcasting and receiving APP, and triggering a PDU conversation release request based on a specific service group.
In the embodiment, if the terminal user quits from the broadcast receiving APP, a PDU Session release request based on a specific service group is triggered, so that the network releases the broadcast receiving resource for the terminal.
According to the technical scheme of the embodiment, the dynamic allocation of resources is realized by requesting the auxiliary network through the PDU session, so that the waste of wireless resources is reduced; the multi-terminal can realize differentiated receiving aiming at different broadcast services, and the broadcast watching experience of the terminal user is enhanced; meanwhile, the same broadcast service is grouped, so that the terminal only receives the broadcast service flow in the same type of group, the broadcasting smoothness of the broadcast service is improved, the receiving load of the terminal is reduced, the power consumption of the 5G terminal is reduced, and the service life of a battery is prolonged.
