For convenience of understanding, some contents related to the embodiments of the present invention are explained below:

first, Multimedia Broadcast Multicast Service (MBMS), and Broadcast Multicast Service (MBS).

In a Long Term Evolution (LTE) system, MBMS/MBS can be transmitted in two ways:

MBMS/MBS transmission mode 1: the MBMS service Single Frequency Network (MBSFN) subframe is transmitted through a Physical Multicast Channel (PMCH) Physical Channel. The Control Information is transmitted through System Information (e.g., System Information Block (SIB) 13) and a broadcast Control Channel (MCCH), and the data is transmitted through an MTCH (broadcast Traffic Channel).

MBMS/MBS transmission mode 2: and a Physical Downlink Shared Channel (PDSCH) scheduled by a Physical Downlink Control Channel (PDCCH). The Control information is transmitted through system information (e.g., SIB20) and a Single Cell Multicast Control Channel (SC-MCCH), and the data is transmitted through a Single Cell Multicast Traffic Channel (SC-MTCH). The SC-MCCH is transmitted through a PDSCH scheduled by a PDCCH (Single Cell Radio Network Temporary Identity, SC-RNTI), and the SC-MTCH is transmitted through a PDSCH scheduled by a PDCCH (Group Radio Network Temporary Identity, G-RNTI).

The MBS service is transmitted through a specific MBMS Radio Bearer (MRB) Radio Bearer. MBS services can be marked by the following identities:

temporary Mobile Group Identity (TMGI);

quality of Service flow identification (QFI).

The core network node is for the same service, and may adopt any one of a unicast mode or a multicast mode to send to the UE. When the core network node sends the service data to the base station in a multicast mode, the core network node sends the same service data to a plurality of base stations at the same time. When the core network node sends service data to the UE in a unicast manner, the core network and the UE establish a unicast bearer through Non-Access Stratum (NAS) signaling interaction.

And II, unicasting.

The unicast reception of the UE is received through a specific unicast Data Radio Bearer (DRB). In the fifth generation (5)^thGeneration, 5G) communication system, the protocol stack for unicast transmission (or reception) comprises, from top to bottom: service Data Adaptation Protocol (SDAP); packet data convergence protocolA conference (Packet Data conversion Protocol, PDCP); radio Link Control (RLC); medium Access Control (MAC).

Three, Dual Connectivity (DC).

The MCG includes a Primary Cell (PCell) and a Secondary Cell (SCell), and the SCG includes a Primary and a Secondary Cell (PSCell). Among them, PCell and PSCell may be called Special Cell (SpCell).

In the embodiment of the present application, the multicast service may be the MBMS or MBS, but is not limited thereto. The bearer is a segment of the path of the connection, such as: the unicast connection between the UE and the core network node comprises unicast bearing between the UE and the network side equipment and unicast bearing between the network side equipment and the core network node; the multicast connection between the UE and the core network node includes a unicast bearer or a multicast bearer between the UE and the network side device, and a multicast bearer between the network side device and the core network node.

Referring to fig. 2, fig. 2 is a flowchart of a processing method provided in an embodiment of the present application. The processing method of the embodiment of the application can be applied to the terminal.

As shown in fig. 2, the processing method may include the steps of:

step 201, receiving first indication information, where the first indication information is used for at least one of: indicating the terminal to establish unicast connection of a first multicast service; and indicating P cells which do not support the second multicast service, wherein P is a positive integer.

In specific implementation, the terminal may receive the first indication information sent by the network side device.

The first indication information is explained below:

in the case that the first indication information is used to indicate that the terminal needs to establish a unicast connection of a first multicast service, the first multicast service may include one or more multicast services.

In the case that the first indication information is used to indicate P cells that do not support the second multicast service, the P cells may be neighbor cells of the terminal, and further, the P cells may include a target cell in a terminal mobility procedure. The second multicast service may be one or more specific multicast services, or may be a multicast service in general. Optionally, the P cells may satisfy at least one of the following: the P cell does not support the second multicast service to be sent through a multicast bearer (e.g., does not support the second multicast service to be sent through an MRB scheduled by an MBS Radio Network Temporary Identity (RNTI)); the P Cell does not support the second multicast service to be sent through a unicast bearer (e.g., the DRB scheduled by a Cell Radio Network Temporary Identity (C-RNTI) is not supported by the P Cell).

In the case that the first indication information is used to indicate P cells that do not support the second multicast service, the following implementation manners may be specifically, but not limited to:

the first implementation mode comprises the following steps: the first indication information is used for indicating that the adjacent cell does not support one or more specific multicast services. In the first implementation, the P cells may be understood as all neighbor cells of the terminal, and the second multicast service may be one or more specific multicast services.

The second implementation mode comprises the following steps: the first indication information is used for indicating that the target cell does not support multicast service. That is, the first indication information is used to indicate that the target cell does not support any multicast service. In the second implementation manner, the P cell may be a target cell in a terminal mobility process, and the second multicast service is a general multicast service.

In addition, the first instruction information is for: in practical application, the terminal may receive a first indication message when indicating that the terminal needs to establish a unicast connection of a first multicast service and indicating that the terminal does not support a P cell of a second multicast service, where the first indication message is used for the terminal to establish a unicast connection of the first multicast service and for the P cell that does not support the second multicast service; the terminal may also receive two pieces of first indication information, where one piece of first indication information is used to indicate that the terminal needs to establish a unicast connection of a first multicast service, and the other piece of first indication information is used to indicate a P cell that does not support a second multicast service.

In this embodiment of the present application, optionally, the first indication information may include information related to a target multicast service, where the target multicast service includes at least one of the following: the first multicast service; the second multicast service. Thus, the terminal can conveniently identify the target multicast service. It should be noted that, in the case that the second multicast service is a general multicast service, the first indication information may not include related information of the multicast service, so that signaling overhead may be saved.

In this embodiment of the application, optionally, the first indication information may include at least one of: cell identities of the P cells; and the frequency point identifiers of the P cells. Thus, the terminal can conveniently identify the P cells. It should be noted that, when the P cell indicates all neighboring cells of the terminal, the first indication information may not include the identification information of the P cell, so that signaling overhead may be saved.

Wherein the first operation may include, but is not limited to, at least one of:

The concrete description is as follows:

in a scenario of initiating a process of establishing a unicast connection of a target multicast service, a terminal may negotiate with a core network node to establish a unicast connection of the target multicast service by sending a Non-Access Stratum (NAS) signaling to the core network node, but is not limited thereto. Therefore, after the terminal successfully establishes the unicast connection of the target multicast service, the terminal can realize the data reception of the target multicast service through the unicast connection, thereby ensuring the data reception continuity of the target multicast service and improving the data reception reliability of the target multicast service.

In a scenario where an Access Stratum (AS) of the terminal sends second indication information to a higher layer of the terminal, the AS of the terminal may indicate, to an NAS of the terminal, related information of a target multicast service, so that the NAS of the terminal may initiate an establishment process of a unicast connection of the target multicast service, and may further implement data reception of the target multicast service through the unicast connection after the unicast connection of the target multicast service is successfully established, thereby ensuring continuity of data reception of the target multicast service and improving reliability of data reception of the target multicast service.

It should be understood that, in the case that the first indication information is only used for indicating that the terminal needs to establish a unicast connection of a first multicast service, the target multicast service includes the first multicast service; under the condition that the first indication information is only used for indicating P cells which do not support a second multicast service, the target multicast service comprises the second multicast service; the first indication information is used for: indicating the terminal to establish unicast connection of a first multicast service; in case P cells that do not support the second multicast service are indicated, the target multicast service may include at least one of the first multicast service and the second multicast service.

In the processing method of the embodiment of the application, the terminal may execute the first operation according to the received first indication information, where the first indication information is used for at least one of: indicating the terminal to establish unicast connection of a first multicast service; indicating P cells which do not support the second multicast service, wherein P is a positive integer; the first operation comprises at least one of: initiating a unicast connection establishment process of the target multicast service; the access layer of the terminal sends second indication information to the upper layer of the terminal, wherein the second indication information is used for indicating the related information of the target multicast service; wherein the target multicast traffic comprises at least one of: the first multicast service; the second multicast service. Therefore, the probability of receiving the data of the target multicast service by the terminal can be improved, and the reliability of receiving the data of the target multicast service can be improved.

In this embodiment of the application, optionally, after the performing the first operation according to the first indication information, the method further includes:

and establishing unicast connection of the target multicast service.

Therefore, under the condition that the terminal successfully establishes the unicast connection of the target multicast service, the terminal can realize the data reception of the target multicast service through the unicast connection, thereby ensuring the data reception continuity of the target multicast service and improving the data reception reliability of the target multicast service.

Optionally, after the unicast connection of the target multicast service is established, the method further includes:

and sending third indication information under the condition that the terminal successfully establishes the unicast connection of the target multicast service, wherein the third indication information is used for indicating the terminal to successfully establish the unicast connection of the target multicast service.

Optionally, the third indication information may include at least one of: relevant information of the target multicast service; unicast bearer identification.

It should be noted that, after the terminal establishes the unicast connection of the target multicast service, the bearer of the target multicast service is a unicast bearer, and therefore, the bearer identifier of the target multicast service is a unicast bearer identifier. Optionally, the unicast bearer identifier may include at least one of: identifying a tunnel; a data stream identification; a session identifier; a radio bearer identity; a logical channel identification.

In an embodiment of the present application, after receiving the first indication information, the method further includes:

and releasing the multicast connection of the target multicast service.

In a specific implementation, the releasing the multicast connection of the target multicast service may include at least one of: releasing unicast bearer in the multicast connection of the target multicast service; and releasing the multicast bearer in the multicast connection of the target multicast service. Such as: under the condition that the first indication information indicates that the P cell does not support the second multicast service through multicast bearing, the terminal can release the multicast bearing in the multicast connection of the second multicast service; and the terminal may release the unicast bearer in the multicast connection of the second multicast service when the first indication information indicates that the P cell does not support the second multicast service through the unicast bearer.

In practice, the terminal may release the multicast connection of the target multicast service after step 201, step 202 or "establishing the unicast connection of the target multicast service".

In addition, the terminal may actively release the multicast connection of the target multicast service, or may perform the multicast connection of the target multicast service under the instruction of the network side device. In the case that the terminal performs multicast connection of the target multicast service under the instruction of the network-side device, optionally, before releasing the multicast connection of the target multicast service, the method further includes: and receiving fourth indication information, wherein the fourth indication information is used for indicating the terminal to release the multicast connection of the target multicast service.

and receiving fifth indication information, where the fifth indication information is used to indicate the terminal to execute a mobility procedure, and a target cell of the mobility procedure belongs to the P cell. After receiving the fifth indication information, the terminal may perform the mobility procedure to access the target cell. In this way, even if the terminal moves from the source cell supporting the second multicast service to the target cell not supporting the second multicast service, since the terminal performs the first operation in advance before moving to the target cell, the probability that the terminal receives the data of the second multicast service can be improved, and the reliability of receiving the data of the second multicast service can be improved.

Optionally, the mobility procedure may be, but is not limited to, any one of the following:
