Abstract: A RAN server, a wireless communications system, and a terminal attach method are provided. The RAN server configured to centrally manage base stations of a plurality of wireless communications standards is introduced, and the RAN server is used as a central node to implement a unified interface to a core network. A base station that is of any wireless communications standard and that is managed by the RAN server may independently provide a data transmission service to a terminal, so that the wireless communications system provided in this application basically does not cause an additional latency. In addition, a TAI unrelated to a wireless communications standard of a base station is carried in an attach request message, an attach accept message, and an attach complete message that are exchanged in a terminal attach process.

Abstract: A handover method, including sending, by a source base station to a source core network device in a process of handing user equipment (UE) over from the source base station to a target base station, a handover required message. The message comprises identification information of a target core network device, and the identification information of the target core network device instructs the source core network device to perform a core network relocation process with the target core network device. The source base station is connected to the source core network device, and the target base station is connected to both the source core network device and the target core network device.

Abstract: Example information transmission methods and apparatus are described. One example method includes determining first information by a relay node, where the first information includes at least one of the following information: a buffer status at a granularity of the relay node, a buffer status at a granularity of an RB between the relay node and at least one first node, a buffer status at a granularity of each first node in the at least one first node, and a buffer status at a granularity of an RB between each first node in the at least one first node and a child node, where the at least one first node is a child node of the relay node. A first packet that carries the first information is sent by the relay node to a second node.

Abstract: Embodiments of the present disclosure provide a multi-connectivity communication method and a device. An access network device of an LTE network sets up a second connection for UE and splits data of the UE through the second connection. The second connection is a connection set up between the UE and the access network device of the LTE network through an access network device of a next generation network. Therefore, dual connectivity between the UE and the LTE network and the next generation network is implemented, a data transmission rate of the UE is increased, and a throughput of the entire network can be increased.

Abstract: A communications system, a core network device and a non-transitory machine-readable medium are provided. In the communications system, a master base station gather traffic statistics information on a service of a user terminal which is transmitted between the user terminal and the master base station through a secondary base station, and sends a message to a core network device. The message includes the traffic statistic information for calculating a charge on the service by the core network device.
