Embodiment 1

[0086] In the present invention, when there is no direct interface between eNBs, the corresponding handover processing flow is shown in Figure 3, which specifically includes the following steps:

[0087] Step 31: The UE reports a measurement report to the source base station, notifying the source base station that handover is required;

[0088] Step 32: When the source base station receives the measurement report and confirms that handover is required, it sends an information request message to the MME as an intermediate entity;

[0089] Step 33: After receiving the information request message, the MME determines the information of each target base station and other handover information that needs to be provided to the source base station;

[0090] Step 34: The MME sends the determined information of each target base station and other handover information to the source base station through an information request response message;

[0091] Step 35: The source base station obta...

Embodiment 2

[0094] The corresponding handover processing flow provided by the present invention is still shown in Figure 3, and specifically includes the following steps:

[0095] In this embodiment, Step 31 to Step 315, and Step 319 are the same as the operation process of Embodiment 1. The difference is that the process of Step 316 to Step 318 is added in Embodiment 2, specifically as follows:

[0096] Step 316: After the source base station confirms that the handover is completed, send the latest context information corresponding to the UE to the MME;

[0097] Step 317: After receiving the latest context information, the MME continues to forward the context information to the target base station;

[0098] Step 318: After acquiring the context information, the target base station compares the latest context information with the previously acquired context information, and determines whether to re-perform the corresponding resource configuration operation according to a preset criterion....

Abstract

The related switch method in wireless communication system comprises: first, SBS of UE determines the UE needs indeed switch operation, obtains target BS message from an intermediate entity; the intermediate entity reports the original and target BS message to SBS; then, according to BS message, SBS executes the switch operation. This invention releases whole system loading, decreases message quantity, and reduces the process complexity for original BS.

Description

technical field [0001] The invention relates to the technical field of wireless communication, in particular to a switching technology in a wireless communication system. Background technique [0002] In a wireless communication system, in order to meet the mobile communication requirements of a mobile terminal, it is necessary to implement a switching function in the system to ensure that the terminal can switch to a different entity to access the network. Generally, the handover process includes three stages: handover decision, handover preparation, and handover execution. [0003] It is stipulated in the WCDMA R6 (R6 for short) standard that in the handover decision stage, the source RNC (radio network controller) obtains the information of the target RNC through the lur interface, including the information of the target RNC logo, interference and load of the target cell, among which , the target RNC completes the provision of cell interference and load information throu...
