application example 1

[0043] image 3 It is a flow chart of a method for processing a handover request response message in the first application example. As shown in the figure, in this example, the UE chooses to re-establish to eNB A after the radio link failure of eNB B occurs, and the specific process is as follows:

[0044] Step 301: UE sends an RRC connection re-establishment request message to eNB A;

[0045] Step 302: eNB A sends a radio link failure indication message to eNB B;

[0046] The radio link failure indication message includes UE identification information;

[0047] Step 303: eNB B sends a handover request message to eNB A;

[0048]eNB B finds the context information of the UE according to the UE identification information in the radio link failure indication message; and sends the context information of the UE to eNB A through a handover request message.

[0049] Step 304: eNB A replies a handover request response message to eNB B;

[0050] The handover request response mess...

application example 2

[0055] This application example is the same as the application example 1 scenario, that is, the UE chooses to re-establish to eNB A after the radio link failure occurs in eNB B, and the specific implementation process is basically the same as that of the application example 1. The difference is that in this application example, the handover command information contained in the handover request reply message sent by eNB A to eNB B is a meaningless byte stream.

[0056] The specific implementation can be: fill in the position of the switching command in the request response message and fill in an empty byte stream with a length of 0;

[0057] Or fill in a byte stream with a fixed length and content, for example: the byte stream 0X00 with a length of 1 pre-stored in the system, etc.

[0058] Or fill in arbitrary byte streams that don't really make sense. For example: randomly generated arbitrary byte stream 0011, etc.

[0059] Compared with the handover request response message...

Abstract

The invention relates to the field of mobile communication, in particular to a processing method and device of switching request response information in a re-establishment process. The method comprises steps that a base station sends wireless link failure indication information, wherein the wireless link failure indication information comprises identification information of user equipment UE suffering from the wireless link failure; switching request information is received, wherein the switching request information carries context information of the user equipment; and switching request response information is sent, wherein the switching request response information does not include switching command information, or switching command information included in the request response information is byte streams without actual meanings. Correspondingly, the invention also provides the user equipment for improving switching success rate. According to the invention, information processing loadof the base station is reduced without affecting completion of re-establishment.

Description

technical field [0001] The invention relates to the field of mobile communication, in particular to a method and a device for processing a handover request response message in a re-establishment process. Background technique [0002] With the advancement of the 3rd Generation Partnership Project (3GPP) technology, the communication industry accelerates the commercial promotion of the Long Term Evolution (LTE) system, and the LTE technology has been increasingly adopted. accepted and mastered by people. In the current protocol, during the X2 handover preparation process of the user equipment (User Equipment, referred to as UE), the source side evolved Node B (evolved Node B, referred to as eNB) sends a handover request (HANDOVER REQUEST) message to the target side eNB. After the work is completed, the eNB on the target side responds with a handover request acknowledgment (HANDOVER REQUEST ACKNOWLEDGE) message to the eNB on the handover source side. The message must contain t...
