Embodiment Construction

[0051] In order to make the above objects, features and advantages of the present application more obvious and comprehensible, the present application will be further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0052] refer to figure 1 As shown, it is a flow chart of the X2 handover in the existing network in which the UE brings the information of the target base station to initiate re-establishment to the source base station and is rejected.

[0053] See below for a description of the process:

[0054] Message 1: The terminal reports a measurement report (MeasurementReport) message to the source base station;

[0055] Message 2: The source base station receives the measurement report reported by the terminal, judges whether the neighboring cell meets the handover threshold, and sends a handover request (HandoverRequest) message to the target base station if the handover threshold is met;

[0056] Message 3: ...

Abstract

The embodiment of the invention provides a radio resource control (RRC) re-establishment processing method which comprises the steps of receiving a radio resource control (RRC) re-establishment request message sent by a terminal; inquiring whether the context of the terminal is available; judging whether the terminal is in an RRC switching process or not if the context of the terminal is available; judging whether the RRC reestablishment request message sent by the terminal carries target cell information or not if the terminal is in a switching process; and judging whether to perform re-establishment processing on the terminal according to the pre-obtained target cell information and the target cell information in the RRC reestablishment request message if the RRC reestablishment requestmessage sent by the terminal carries the target cell information. A source base station does not directly send an RRC reestablishment rejection message to a UE, so that the wire dropping rate of the UE in the network is reduced, and the user perception is improved.

Description

technical field [0001] The present application relates to the field of communication technologies, and in particular, to a radio resource control (RRC) reestablishment processing method and a radio resource control (RRC) reestablishment processing device. Background technique [0002] In an actual wireless network, during the handover process of the user terminal UE (User Equipment) from the source base station to the target base station, after receiving the RRC connection reconfiguration message (RRCConnectionReconfiguration) sent by the source base station, the UE will send the RRC connection reconfiguration complete message ( RRCConnectionReconfigurationComplete) sends the target base station, but due to interference or environmental factors, the upper layer of the target base station may not receive the message, but the terminal does not know this situation, the UE receives msg2 (Random Access Response) and sends the msg3 message After the (reconfiguration complete messa...
