Embodiment Construction

[0076] The technical solutions in the embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings of the present invention.

[0077] See figure 1 , is a schematic diagram of a network framework provided by an embodiment of the present invention. The network framework schematic diagram includes a core network, a first base station, a second base station, and a user terminal (User Equipment, UE). Optionally, the network framework schematic diagram may also include other base stations, such as the third base station shown in the figure.

[0078] In some embodiments, after the UE establishes an RRC connection with the first base station and the terminal is in the RRC connection state, if due to the mobility of the terminal, the terminal moves from the first base station to the coverage of the second base station and the first base station If it is decided to switch the terminal to the second base station, the first base st...

Abstract

The embodiment of the invention discloses a data transmission method, a related device, and a system. The method includes the steps that a first base station receives a first message sent by a secondbase station, wherein the first message is used to indicate the second base station to perform the transmission of data; the first base station transmits a second message to the second base station, wherein the second message carries at least one address, and the address is associated with the data. By implementing the embodiments of the invention, the method can solve a problem that one end doesnot know how to identify the data to be transmitted, and the other end does not know the currently received data when the first base station and the second base station perform data transmission in the prior art, thereby improving the efficiency of data transmission.

Description

technical field [0001] The present invention relates to the technical field of communications, and in particular to a data transmission method, related equipment and a system. Background technique [0002] In the next generation network (5G), three radio resource control (Radio Resource Control, RRC) states are defined for user equipment (User Equipment, UE): RRC Idle State (RRC Idle State), RRC Deactivation State (RRC Inactive State), RRC Connected State (RRC Connected State). [0003] When the terminal is in the RRC deactivated state, when the terminal moves inside the notification area (RAN based Notification Area, RNA) of the radio access network (Radio Access Network, RAN), it will not feed back the channel quality status to the network side, and when moving out The network needs to be notified after the RNA. Wherein, the RNA is composed of one cell or multiple cells. If it is composed of multiple cells, the multiple cells belong to the same base station, and may also...
