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 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: In this application, a terminal determines a power control parameter, and the terminal determines a transmit power based on the determined power control parameter. The power control parameter includes an interference impact parameter or a path correction parameter of a downlink path loss, and the path correction parameter of the downlink path loss is used to correct a downlink path loss participating in calculation of the transmit power. The interference impact parameter and the path correction parameter of the downlink path loss are determined and obtained based on neighboring cell information of the terminal, and the neighboring cell information includes some or all of the following information: a reference signal transmit power of a neighboring cell, an uplink interference over thermal noise ratio of the neighboring cell, and uplink load of the neighboring cell.

Abstract: Embodiments of the present disclosure provide a multi-connectivity communication method and a device. An access network device of a first network determines to use an access network device of a second network to perform data splitting for data of UE, and then sends first splitting configuration information to the UE and sends second splitting configuration information to the access network device of the second network. The first splitting configuration information is used to notify the UE that the access network device of the second network is to split to-be-split data of the UE. The second splitting configuration information is used to instruct the access network device of the second network to split the to-be-split data of the UE.
