Method and device for controlling transmission of dual-connection X2 state report and auxiliary base station

Abstract

The invention provides a method and a device for controlling transmission of a dual-connection X2 state report and an auxiliary base station. The method is applied to the auxiliary base station, and comprises the following steps: receiving an X2 data message sent by a main base station, and judging whether a preset moment when the X2 state report is transmitted to the main base station arrives or not in real time; and when the preset moment when the X2 state report is transmitted arrives, transmitting the X2 state report to the main base station. According to the scheme, transmission control is performed on the X2 state report of the auxiliary base station according to a transmission moment, so that transmission of the X2 state report can be more reasonable, accurate and immediate.

Description

technical field [0001] The present invention relates to the technical field of wireless communication, in particular to a method, device and secondary base station for controlling the transmission of a dual connectivity X2 status report. Background technique [0002] At present, there are mainly two schemes for TDD-FDD Joint Operation (time division duplex-frequency division duplex shared operation) in the standard: CA (conditional access) and dual connection. Suitable for different manufacturers. The dual-connection solution supports non-ideal backhual (two-way loopback link), does not require co-site, and supports interconnection between different manufacturers. The network diagram is as follows figure 1 . [0003] When the core network EPC (Evolved Packet Core, packet core evolution) sends data to the terminal UE, the data will first arrive at the main base station MeNB, and then the MeNB will pass some or all of the data packets through the X2 link ( A communication l...

Problems solved by technology

[0005] The technical problem to be solved by the present invention is to provide a method, device and secondary base station for controlling the sending of dual connectivity X2 status report, so as to solve the problem that the secondary base station needs to send a status report to the primary base station during the transmission process of the existing X2 data message , the standard protocol does not accurately describe when to send the status report from the secondary base station to the primary base station, which may cause frequent status reports to occupy the bandwidth of the X2 link, or the feedback of the status report is not timely, resulting in a large amount of data on the secondary base station Insufficient, even cut-off, or too many packets stored on the main base station, resulting in overflow packet loss and cut-off
