摘要： The present invention provides a cell selection method and apparatus. The cell selection method includes: sending, by a non-access stratum of user equipment UE, network list information to an access stratum of the UE, where the network list information includes a list of forbidden networks and a list of forbidden networks for a GPRS service; determining, by the non-access stratum, indication information about a cell selection priority according to an operation mode of the UE; and sending, by the non-access stratum, the indication information to the access stratum, so that the access stratum selects a suitable cell according to the network list information and the indication information. The present invention can effectively prevent the UE from entering a state of being able to normally camp but unable to obtain a normal service, thereby improving user experience.

摘要： Embodiments of the present invention provide a method for determining a measurement gap length and a network device. The method includes the following steps: determining, by a first network device, whether a master eNodeB is synchronous with a secondary eNodeB; and when the master eNodeB is synchronous with the secondary eNodeB, determining, by the first network device, that the measurement gap length is a first length; or when the master eNodeB is not synchronous with the secondary eNodeB, determining, by the first network device, that the measurement gap length is a second length; where the first length is less than the second length.

摘要： Example configuration methods and apparatus are described. An example communications system includes a master node and a secondary node that jointly provide a service for a terminal. One example method includes generating configuration information for a signaling radio bearer (SRB) by the secondary node, where the SRB is used to transmit a radio resource control (RRC) message between the secondary node and the terminal. The secondary node sends the configuration information for the SRB to the master node, so that the configuration information for the SRB is sent to the terminal through the master node. The secondary node receives a result of configuring the SRB by the terminal by using the configuration information for the SRB. In this way, the SRB can be established on the secondary node, and used for RRC message transmission between the secondary node and the terminal.
