Radio resource control rrc message processing method, device and system

Abstract

The embodiment of the present invention relates to a radio resource control RRC message processing method, device and system, the method includes: the first serving node establishes a connection with a first anchor node, and the first anchor node establishes a connection with a mobility management entity MME The first serving node receives a radio resource control RRC message sent by the first user equipment UE, and the RRC message includes an RRC message carried by a signaling radio bearer SRB1 or an RRC message carried by SRB2; The first anchor node sends the RRC message, so that the first packet data convergence protocol PDCP layer entity in the first anchor node processes the RRC message carried by the SRB1 and sends it to the RRC of the first anchor node or, the second PDCP layer entity of the first anchor node processes the RRC message carried by the SRB2 and sends it to the RRC layer entity of the first anchor node. Therefore, the signaling load of the core network can be effectively reduced.

Description

technical field [0001] The present invention relates to the field of mobile communication, in particular to a radio resource control RRC message processing method, device and system. Background technique [0002] With the increasing number of user equipment (UE, User Equipment), the existing wireless communication system can no longer meet the wireless communication needs of users. Therefore, it is urgent to increase the system capacity of the wireless communication system. The method of adding base stations can be used to increase the system capacity. To achieve this, a typical approach is to densely deploy many small base stations in a macro cell, thereby forming more micro cells. However, most UEs will be connected to a base station, and the base station provides wireless communication services for the UE. For simplicity of description, the network device that will provide wireless communication services for the UE is called a serving node of the UE. The above-mentioned s...

Problems solved by technology

Since the serving node is connected to the mobility management entity (MME, Mobility Management Entity) through the control plane interface, and the serving node is connected to the serving gateway (SGW, Serving Gateway) through the user plane interface, when the serving node of the UE is switched After that, it is necessary to send signaling between the new serving node and the MME to update the S1 control plane connection between the serving node and the MME. At the same time, the MME and the SGW also need to send signaling to update the S1 user plane connection between the serving node and the SGW. In this way, each handover process will bring at least 4 messages. When the deployment density of base stations increases, the number of handovers will increase sharply, which will cause a sharp increase in the signaling load of the core network; When the MME has a paging message to send, the MME will send a paging message to all base stations in the tracking area (TA, tracking area) area corresponding to the paging message, resulting in a sharp increase in the signaling load of the core network
