Abstract

The invention aims to provide a method, equipment and a system for transmission control on user equipment. The method includes: when the user equipment forms dual connectivity with a corresponding macro eNB and a small eNB, determining transmission status information corresponding to a DRB (data radio bearer) established with the user equipment through the user equipment, sending the transmission status information to the macro eNB, then determining transmission configuration information corresponding to the user equipment through the macro eNB according to the transmission status information, and performing transmission configuration on the user equipment according to the transmission configuration information. Compared with the prior art, the method, equipment and system has the advantages that on the basis of dual connectivity, PDU needing transmission or retransmission is acquired according to the transmission status information of the user equipment or the macro eNB performs traffic control on the user equipment according to transmission status information, so that connection establishment and switching of the user equipment, the macro eNB and the small eNB are guaranteed, reliability in data transmission is improved, efficiency of resource allocation of the system is improved, power consumption of the system is lowered and the like.

Description

technical field [0001] The present invention relates to the communication field, and in particular to a technology for performing transmission control on user equipment. Background technique [0002] Currently, if the user equipment is connected to the macro base station or the small base station through a single connection mode, that is, the user equipment is only connected to one of the macro base station or the small base station, the user equipment in the network When moving between cells, it is necessary to continuously switch between the macro base station and the small base station, which can easily cause handover failure. [0003] In the standard R12 of 3GPP LTE, a new research project "Small Cell Enhancement for E-UTRA and E-UTRAN-High Level" is proposed. One of the important aspects is to support macro cells (cells covered by macro base stations) ) layer and the dual connectivity of the small cell layer. [0004] figure 1 It shows dual connectivity of user equip...
