Detailed Description
The inventor notices in the process of invention that:
fig. 2 is a schematic diagram of a service establishment process initiated by a core network in 5G, and the service establishment process is generally initiated by a relevant process of the core network in an existing UE RRC (Radio Resource Control) connection establishment process, for example, the service establishment process initiated by the core network in 5G is shown in fig. 2.
In this process, a paging message from the AMF (Access and Mobility Management Function) triggers a RAN (Radio Access Network) side to establish a communication service process for the UE. Similarly, the unicast mode of MBMS is also established through this procedure.
As can be seen, in the existing 4G MBMS technology, the EPC (Evolved Packet Core) controls the state transition of the UE, for example: the transition from Idle to connected, or vice versa, such a technique will not enable a fast state transition for MBMS service reception, thereby more efficiently using the radio network resources for the transmission of MBMS services. Especially for MBMS service reception in RRC connected state, dynamic state control by the RAN is required.
However, the existing 4G MBMS technology supports MBSFN (Multicast Broadcast Single Frequency Network) and SC-PTM transmission schemes, and allows UEs in idle or connected state to receive MBMS services. The 5G NR (New Radio) also has a need for multicast/broadcast services as a New generation Radio access technology network. In order to make the 5G multicast technology architecture simpler and more efficient, it is necessary to support the RAN network to perform state management for the terminal receiving the MBMS service, but the existing 4G MBMS technology controls the state transition of the UE by the EPC, for example: the conversion from Idle to connected, or vice versa, and so on, such technologies cannot accommodate the development and evolution of new 5G NR MBMS technology architectures.
Based on this, the embodiment of the present invention provides an MBMS service reception indication and an MBMS service reception scheme, so as to more efficiently use radio network resources to transmit an MBMS service.
The following describes embodiments of the present invention with reference to the drawings.
In the description process, the implementation of the UE and the RAN side will be described separately, and then an example of the implementation of the UE and the RAN side in cooperation with each other will be given to better understand the implementation of the scheme given in the embodiment of the present invention, and related functional entities will be described in specific examples. However, such descriptions do not mean that they must be implemented cooperatively or separately, and actually, when these functional entities are implemented separately, they each solve the problem on their own side, and when they are used in combination, they can achieve better technical effects.

is a NG-RAN node, an indication sent when initiating a paging procedure for UEs interested in MBMS services.
In the implementation, on the NG-RAN node side, the mode that the UE enters the RRC connected state to receive the MBMS service is: an MBMS broadcast transmission mode with uplink feedback, or an MBMS unicast transmission mode.
In implementation, on the UE side, the mode that the UE enters the RRC connected state to receive the MBMS service is: an MBMS broadcast transmission mode with uplink feedback, or an MBMS unicast transmission mode.

Specifically, the mode of receiving the MBMS after the UE enters the RRC connected state will include an MBMS broadcast transmission mode or an MBMS unicast transmission mode with uplink feedback;
step 604: RRC connection setup procedure;
specifically, once the terminal in idle state decides to receive a specific MBMS service, based on the indication information, the following steps are performed:
