Abstract: The present invention discloses a method and system for reselecting or handing over to a broadcast multicast cell. The method includes the following steps: broadcasting, by an MBMS cell, a service area identity list of a service area to which the MBMS cell belongs; determining, by a UE, whether the service area identity list includes a service area identity corresponding to a service; if the service area identity list includes service area identity corresponding to the service, setting, by the UE, a cell reselection priority of a frequency of an MBMS cell to the highest. According to the present invention, a UE can identify whether a cell capable of providing services that the UE is receiving or is interested in around the UE, so that the cell can learn which neighboring cells are MBMS cells and what services are being broadcast in MBMS cells if such MBMS cells are available.

Abstract: A communication method and a related apparatus provide for differences between internal resources of a base station to support different slice service capabilities on a RAN side. In the communication method, when a first distributed unit (DU) sets up a connection to a first central unit (CU) but the first CU does not support a first slice, and a second CU supports the first slice, the first DU may establish a connection to the second CU based on transport layer information of the second CU and an identifier or a name of the second CU, or the second CU may update the connection between the first CU and the first DU to a connection between the second CU and the first DU. A difference between internal resources of a base station can be more fully utilized to support different slice service capabilities on a RAN side and improve flexibility and coverage of providing a slice service for user equipment.

Abstract: A data sending method includes: receiving, by a terminal device, configuration information sent by a network device, where the configuration information is used to configure a non-scheduling resource; and starting, by the terminal device when a condition is met, a first timer, where the non-scheduling resource is not used for sending uplink data within duration of the first timer. According to the method, a timer is set on the terminal device, and the timer is used to instruct the terminal device whether to send data on a non-scheduling resource. Therefore, a data sending success rate and a communication latency of the terminal device can be effectively balanced.
