It should be noted that the present disclosure should not be limited to the specific embodiments described below. In addition, for the sake of brevity, detailed descriptions of well-known technologies not directly related to the present disclosure are omitted to prevent confusion of understanding of the present disclosure.

In the present disclosure, the network, the base station, and the RAN may be used interchangeably, and the network may be a long term evolution LTE network, an NR network, an enhanced long term evolution LTE network, or other networks defined in subsequent evolution releases of 3 GPP.
In LTE SC-PTM, a base station broadcasts a Multimedia Broadcast Multicast Service (MBMS) service supported by the base station and scheduling information thereof through system information and information transmitted on an SC-MCCH channel, and radio bearer configuration information for transmitting the MBMS service is predefined. The UE can know the MBMS service supported or ongoing by the current cell or base station by receiving the corresponding system information and the message transmitted on the SC-MCCH. When UE needs to receive a certain MBMS service, a radio bearer is established according to predefined parameters and data is received. In this case, the UE can receive the MBMS service without establishing an RRC connection.
In NR MBS, a part of MBS services (service) may also be scheduled in a similar manner as SC-PTM, so that UEs in RRC idle state and RRC inactive state may also receive the MBS services. However, there is another part of MBS service that requires the UE to establish RRC connection with the base station, and then the base station configures the UE through dedicated RRC signaling, and the radio bearer receiving these MBS services can also be configured for the UE by the base station through dedicated RRC signaling. How the UE distinguishes the two types of MBS services so that the UE decides whether to enter RRC connected state and whether to establish and configure radio bearers with predefined parameters to receive the MBS services of interest is a problem to be solved.
In the embodiment of the present disclosure, two types of MBS services are defined, namely, a first type of MBS service and a second type of MBS service. The related information of the first MBS service is broadcasted in the information transmitted on the system information SIB or MBS-MCCH. And the related information of the second MBS service is configured for the UE through the special RRC signaling. In other words, if the UE is interested in the second MBS service, the UE needs to establish an RRC connection with the base station first. The related information of the first MBS service and the second MBS service may include one or more of the following items: a common RNTI (denoted as g-RNTI) corresponding to each MBS session or service, time domain and/or frequency domain scheduling information of each MBS session or service, a session identifier or service identifier, a logical channel identifier for transmitting user data of the session or service, and the like. Furthermore, configuration information (e.g., RLC configuration, sequence number length configuration, etc.) of the radio bearer for delivering (delivery) the first type MBS service may be predefined; the radio bearer for delivering (delivery) the second type MBS service may be configured for the UE by the base station through dedicated RRC signaling.
It should be noted that an MBS service or session may be identified by an MBS id, which may be a TMGI and/or a session id sessionId, where the TMGI may include a PLMN id and/or a service id, and the service id uniquely identifies an MBS service in a PLMN.
In addition, it should be noted that the total number of the first type MBS services and the second type MBS services supported by the base station does not exceed the maximum value of the number of MBS supportable by the system, and this value may be predefined.

In step S101, system information and/or an MBSConfiguration message transmitted on an MBS-MCCH are received from a base station, and MBS types supported by the base station are indicated in the system information and/or MBSConfiguration message. In step S102, according to the MBS type supported by the base station, an operation corresponding to receiving the MBS is performed.
According to the method 100, the time delay for the UE to acquire the MBS supported by the base station is reduced and the energy consumption of the UE is saved by indicating the MBS supported by the base station in the system information and/or the MBSConfiguration message.

In step S302, the system information and/or the MBSConfiguration message are sent, so that the user equipment UE performs an operation corresponding to receiving the MBS according to the MBS type supported by the base station.
According to the method 300, the time delay for the UE to acquire the MBS supported by the base station is reduced and the UE energy consumption is saved by indicating the MBS supported by the base station in the system information and/or the MBSConfiguration message.

The memory 402 has stored thereon program instructions. Which when executed by the processor 401 may perform the above-described method in the base station as detailed in the present disclosure.
Fig. 5 shows a schematic diagram of an embodiment of the present disclosure.
In step 001, the UE receives system information from the base station and/or RRC message transmitted on MBS-MCCH, which is denoted as MBSConfiguration message.
The following describes in detail a method for a base station to indicate a first MBS service and/or a second MBS service supported by the base station through system information and/or an MBSConfiguration message transmitted on an MBS-MCCH. The MBSConfiguration message contains control information applied to MBS services transmitted through the radio bearer MRB.
Example 1
The first MBS service supported by the base station is indicated in MBS-MCCH, and the second MBS service is indicated in system information SIB. Specifically, the system information includes a field (denoted as mbsferrcconnected), where the field indicates a second type MBS service or session (session) list supported by the base station, and each element in the list is an MBS identifier. The system information may further include information required for acquiring MBS control information corresponding to the first-type MBS service, where the MBS control information or a message MBSConfiguration including the MBS control information is transmitted on a logical channel MBS-MCCH. The MBSConfiguration message may include an MBS identifier corresponding to a first MBS service supported by the base station, time domain and/or frequency domain scheduling information of the first MBS service, and/or a common RNTI and/or a logical channel identifier for transmitting the session or service user data, and the like.
In the present disclosure, the first type MBS service or the second type MBS service supported by the base station may also be described as the first type MBS service or the second type MBS service that is ongoing or about to start.
Example 2
The first type of MBS service and the second type of MBS service supported by the base station are both indicated in the RRC message transmitted on the MBS-MCCH, where the RRC message is denoted as MBSConfiguration message, and the MBS-MCCH or the scheduling information of the MBSConfiguration message transmitted thereon is indicated in the system information (in a manner similar to LTE SC-PTM may be used). Specifically, the MBSConfiguration message includes a field (denoted as mbsferrcconnected), where the field indicates a second-type MBS session (session) list supported by the base station, and each element in the list is an MBS id. Whether the corresponding MBS session is the first type MBS service or the second type MBS service can also be implicitly indicated by whether the relevant parameters of a certain MBS service or certain MBS services are configured. For example, if the configuration information corresponding to a certain MBS session does not include the common RNTI field g-RNTI, the MBS session is considered to be the second type MBS. The public RNTI is used for scrambling data corresponding to the corresponding MBS conversation, and the UE receives the corresponding MBS conversation by detecting the public RNTI. The configuration information corresponding to the MBS session may further include an indication of an explicit indication of whether the corresponding MBS session is the first-type MBS service or the second-type MBS service, or an indication of a display of an indication of whether the corresponding MBS session is the second-type MBS service.
The first and second MBS services described in this disclosure are for MBS sessions.
Example 3
The first MBS service and the second MBS service supported by the base station are both indicated in the system information. Specifically, the system information includes two fields, one field is used for indicating a first MBS session list supported by the base station, and the other field is used for indicating a second MBS service or session list supported by the base station. Each element in the list is an MBS identification. Or, the system information includes an MBS service or session list supported by the base station, and each element in the list indicates whether it is the first-type MBS service or the second-type MBS service. For example, the MBS service or session corresponding to the indication containing an identifier explicit is the first MBS service or the second MBS service, or the MBS service or session corresponding to the indication containing an identifier display is the second MBS service, in this case, if the configuration of the MBS service or session does not contain the identifier, the MBS service is the first MBS service. Or, a bitmap may be used to indicate that bits in the bitmap correspond to elements in an MBS service or session list one-to-one, and different values of the bitmap identify the type of the MBS service or session. For example, if the value in the bitmap is 1, it indicates that the corresponding MBS service or session is the first type of MBS service, and the value is 0, it indicates that the corresponding MBS service or session is the second type of MBS service, or vice versa.
In step 002, if the system information and/or the MBSConfiguration message contains MBS service or session that the UE is interested in, and the MBS service or session is a second MBS service, the UE establishes RRC connection with the base station. The specific process of establishing RRC connection between UE and base station is described in 3GPP TS38.331 latest document. It should be noted that a new connection establishment reason may be defined for the RRC connection establishment procedure triggered by the MBS service reception requirement, or the reason "mt-Access" defined in the current 3GPP protocol may be adopted, where the RRC connection establishment procedure includes a UE-initiated RRC connection establishment procedure in an RRC IDLE state and a UE-initiated RRC resume (resume) procedure in an RRC _ INACTIVE state. Specifically, the corresponding instancementcause is set to receive a new reason defined by MBS or a reason "mt-Access" defined in the current 3GPP protocol in the request message rrcconnectionrequest for establishing RRC connection, or the corresponding resumecuse is set to receive a new reason defined by MBS or a reason "mt-Access" defined in the current 3GPP protocol in the request message rrcconnectionresuquest for continuing a suspended RRC connection.
In step 003, the UE reports (also called indicates) MBS services of interest (interested) to the base station.
Specifically, under the condition that the base station configures the MBS service or session that the base station is interested in reporting, the UE may indicate the MBS service or session that the base station is interested in to the base station through the ueassistance information message for indicating the UE assistance information, and report the MBS service or session that the base station is interested in again when the MBS service or session that the base station is interested in changes.
New RRC messages may also be defined for the UE to report its interested MBS services or sessions.
Triggering the UE to report its interested MBS service or session may be one of the following cases: the UE successfully establishes the RRC connection, the interested MBS service or session is not reported by the UE after the RRC connection is established, and the interest of the UE is changed.
In step 004, the UE receives an RRC reconfiguration message from the base station. The reconfiguration message contains the configuration information of the radio bearer corresponding to the interested MBS conversation.
Specifically, the UE receives an RRC reconfiguration message from the base station, where the message includes configuration information of a radio bearer corresponding to an MBS service or session, and the configuration information includes an MBS service or session associated with the radio bearer, and may specifically be an MBS identifier corresponding to the MBS service or session. Optionally, the MBS service or session is one of the second type MBS services or sessions obtained by the UE in step 001.
As described in the present disclosure, by indicating the MBS service supported by the base station in the system information and/or the MBSConfiguration message, the time delay for the UE to acquire the MBS service supported by the base station is reduced, and the energy consumption of the UE is saved.
