Detailed Description
In the prior art, a protocol specifies that an MBMS service may be carried on an SCC of a secondary base station service, which results in that while a UE still needs to monitor a primary base station, the UE also needs to receive the MBMS service and enhanced MBMS service data from the secondary base station, thereby increasing a requirement for the UE to process service capabilities at the same time.
Referring to fig. 1, fig. 1 is a data flow diagram of a method for receiving an MBMS service in the prior art. The method for receiving the MBMS service may be used for a main base station, and may further include steps S101 to S110, which are described below.
In step S101, the main base station 11 establishes connection with the user terminal 13.
Wherein the step of establishing the connection may be established by using a random access procedure.
In step S102, the main base station 11 saves the UE capability message.
The UE capability message may be reported to the main base station 11 by the user terminal 13 in the access process, so that the main base station 11 stores and judges whether the user terminal 13 supports the MBMS service after receiving the UE capability message.
In step S103, the main base station 11 receives the UE-reported cell measurement from the user terminal 13.
In step S104, the main base station 11 determines to add the secondary base station.
Specifically, the main base station 11 may determine whether to add an auxiliary base station to the user terminal 13 according to a cell measurement result reported by the user terminal 13.
In step S105, the main base station 11 transmits a secondary base station information request to the secondary base station 12.
In step S106, the main base station 11 receives the secondary base station information from the secondary base station 12.
Specifically, the main base station 11 may establish a connection between the user terminal 13 and the secondary base station 12 according to the secondary base station information acquired from the secondary base station 12.
In step S107, the main base station 11 transmits an addition reconfiguration instruction to the user terminal 13.
In step S108, the main base station 11 receives addition reconfiguration complete information from the user terminal 13.
Specifically, the reconfiguration instruction may include the information of the secondary base station, and the main base station 11 may enable the user terminal 13 to establish a connection with the secondary base station 12 by sending the reconfiguration instruction to the user terminal, and further send reconfiguration completion information to the main base station 11 after the connection is successful.
In step S109, the user terminal 13 listens to the main base station 11.
In step S110, the user terminal 13 receives the MBMS service from the secondary base station 12.
Specifically, although the user terminal 13 may receive the MBMS service from the secondary base station 12, there may then be other types of services that need to be received from the main base station 11, resulting in the user terminal 13 needing to have the capability of simultaneously processing the services of the main base station 11 and the secondary base station 12.
The inventor of the present invention finds, through research, that increasing the requirement of the UE for simultaneously processing the service capability may cause that part of the existing UEs are difficult to support, which affects market share. Specifically, for example, the UE needs to have a higher master frequency capability to process more physical layer parallel services, more memory space is needed to support processing services such as symbol buffering, HARQ Buffer, equalization, decoding, and the like, and these resources cannot be updated on a mass-produced chip.
Specifically, the 3GPP protocol introduces MBMS services and then continuously upgrades to enhanced MBMS (also called eMBMS) and Single-Cell Point-to-Multipoint (SC-PTM) services, and in case of multi-CC, the protocol specifies the capability that the related MBMS services can be carried on the SCC. In a conventional Carrier Aggregation (CA) service, a change of service bearer information and system information is notified to a UE on a PCC through a message, and there is no need for monitoring and acquiring a new common message on an SCC. The MBMS service and the enhanced MBMS service time-frequency information are carried by the messages of the common channels SIBs and the change of the information is expressed by SIB1 or Paging, so that the MBMS service is carried on the SCC under the condition of multi-CC, and the capability requirement of multi-UE for processing the service is improved.
In the embodiment of the invention, when receiving the MBMS service, determining whether the auxiliary base station needs to send the data of the MBMS service; and when determining that the data of the MBMS needs to be transmitted by the secondary base station, exchanging the data with the secondary base station. By adopting the scheme, when the main base station receives the MBMS and determines that the auxiliary base station needs to send the data of the MBMS, the main base station exchanges with the auxiliary base station, so that the UE only needs to monitor the base station sending the data of the MBMS, namely, monitors the auxiliary base station before exchanging, but not monitors the main base station before exchanging, thereby reducing the maximum parallel service processing capacity of the UE when the MBMS is introduced, realizing the MBMS even if the UE does not have the capability of processing the services at the same time, namely, reducing the capability requirement on the UE.
In order to make the aforementioned objects, features and advantages of the present invention comprehensible, embodiments accompanied with figures are described in detail below.
Referring to fig. 2, fig. 2 is a flowchart of a method for exchanging a primary base station with a secondary base station according to an embodiment of the present invention. The method for receiving the MBMS service may be used for a master base station, and may further include steps S21 to S22:
step S21: when receiving MBMS service, determining whether the data of the MBMS service needs to be transmitted by a secondary base station;
step S22: and when determining that the data of the MBMS needs to be transmitted by the secondary base station, exchanging the data with the secondary base station.
In the specific implementation of step S21, there may be a case where the primary base station cannot transmit the data of the MBMS service, and the secondary base station needs to transmit the data of the MBMS service.
Further, the step of the primary base station determining whether the data of the MBMS service needs to be transmitted by the secondary base station may include: when the data related to the MBMS service is not supported to be transmitted, determining that the data of the MBMS service needs to be transmitted by the auxiliary base station; or, when the admission control capability is not enough to support the transmission of the data related to the MBMS service, determining that the data of the MBMS service needs to be transmitted by the secondary base station.
In the embodiment of the invention, when the main base station cannot transmit the data related to the MBMS due to non-support or insufficient admission capacity, the requirement of the user terminal on the MBMS can be met by determining that the auxiliary base station needs to transmit the data of the MBMS.
In the specific implementation of step S22, when it is determined that the data of the MBMS service needs to be transmitted by the secondary base station, the primary base station exchanges with the secondary base station.
Referring to fig. 3, fig. 3 is a flowchart of an embodiment of step S22 in fig. 2, and the step of exchanging with the secondary base station may include steps S31 to S35, each of which is described below.
In step S31, before sending the exchange instruction to the secondary base station, the primary base station determines whether the secondary base station is activated for the UE.
In a specific implementation manner of the embodiment of the present invention, after the primary base station sends the addition reconfiguration instruction to the UE and further receives the addition reconfiguration complete message from the UE, the secondary base station may be set to be activated on the UE side, so that data transmission may be performed via the secondary base station when needed.
In another specific implementation manner of the embodiment of the present invention, after the main base station sends the addition reconfiguration instruction to the UE and further receives the addition reconfiguration complete message from the UE, the auxiliary base station may be configured not to be activated immediately on the UE side, but to be activated after waiting for receiving the activation instruction of the main base station.
In the embodiment of the present invention, there is no limitation to specifically select which specific embodiment is described above.
In step S32, the primary base station transmits a secondary base station activation instruction to the UE if the secondary base station has not been activated for the UE.
In the embodiment of the present invention, if the secondary base station is not activated for the UE due to the aforementioned setting reason or other reasons, the step of determining, by the primary base station, whether the secondary base station is activated for the UE may be performed when the secondary base station is activated for the UE, and may also be performed when the secondary base station is not activated for the UE, by sending a secondary base station activation instruction to the UE to activate the secondary base station.
In step S33, the primary base station transmits an exchange instruction including exchange instruction information to the secondary base station.
Further, the exchange indication information may be an identifier; when the value of the identifier is one of 1 or 0, the exchange indication information is used for indicating that the exchange between the main base station and the auxiliary base station exists; the exchange indication information indicates that there is no exchange of the primary base station with the secondary base station when the value of the identifier is the other of 1 or 0.
Specifically, 1 bit may be used to indicate the exchange indication information, for example, when the value of the 1 bit is 1, it indicates that there is exchange between the primary base station and the secondary base station, and when the value of the 1 bit is 0, it indicates that there is no exchange between the primary base station and the secondary base station.
In the implementation of the invention, the main base station is arranged to send the exchange instruction to the auxiliary base station, so that the auxiliary base station can clearly determine the requirement of the main base station after receiving the exchange instruction.
In step S34, an exchange response is received from the secondary base station, and the exchange response is used to indicate that an exchange is performed.
In a specific implementation, since the secondary base station has established a connection with the primary base station, when the secondary base station has a capability of supporting transmission of data related to the MBMS service and the admission control capability is sufficient to support transmission of data related to the MBMS service, an exchange response may be issued to indicate that exchange with the primary base station is possible.
It should be noted that if the secondary base station does not have the capability of supporting the transmission of the data related to the MBMS service or the admission control capability is not sufficient to support the transmission of the data related to the MBMS service, the secondary base station may be configured not to transmit the exchange response, and may be configured to transmit the exchange response to reject the exchange with the primary base station. In the embodiment of the present invention, there is no limitation on which manner the secondary base station rejects to exchange with the primary base station.
In step S35, an exchange reconfiguration instruction is sent to the UE, so that the UE sends exchange reconfiguration complete information to the secondary base station.
Wherein the exchange reconfiguration instruction may include the identity of the secondary base station and the exchange indication information.
In the embodiment of the present invention, by setting the switching reconfiguration instruction to include the identity of the secondary base station and the switching indication information, after receiving the switching reconfiguration instruction, the UE can determine, according to the switching indication information, that the exchange between the primary base station and the secondary base station occurs, and determine, according to the identity of the secondary base station, which secondary base station is to be switched to the primary base station, so that the UE is given an opportunity not to monitor the primary base station before the exchange, thereby reducing the maximum parallel service throughput of the UE when introducing the MBMS service.
In the embodiment of the invention, when the main base station receives the MBMS and determines that the auxiliary base station needs to send the data of the MBMS, the main base station exchanges with the auxiliary base station, so that the UE only needs to monitor the base station sending the data of the MBMS, namely, the auxiliary base station before exchanging, but not the main base station before exchanging, thereby reducing the maximum parallel service processing capacity of the UE when the MBMS is introduced, and realizing the MBMS even if the UE does not have the capability of processing the services at the same time, namely, reducing the capability requirement of the UE.
Referring to fig. 4, fig. 4 is a data flow diagram of a method for receiving an MBMS service according to an embodiment of the present invention. The method for receiving the MBMS service may include steps S401 to S414, and the steps are described below.

The UE capability message may be reported to the main base station 41 by the UE 43 during an access process, so that the main base station 41 stores and determines whether the UE 43 supports the MBMS service after receiving the UE capability message.
In step S403, the main base station 41 receives the UE-reported cell measurement from the user terminal 43.
In step S404, the main base station 41 determines to add the secondary base station.

In step S414, the ue 43 monitors the secondary base station 42 and receives the MBMS service.
In the embodiment of the invention, when the main base station receives the MBMS and determines that the auxiliary base station needs to send the data of the MBMS, the main base station exchanges with the auxiliary base station, so that the UE only needs to monitor the base station sending the data of the MBMS, namely, the auxiliary base station before exchanging, but not the main base station before exchanging, thereby reducing the maximum parallel service processing capacity of the UE when the MBMS is introduced, and realizing the MBMS even if the UE does not have the capability of processing the services at the same time, namely, reducing the capability requirement of the UE.
