Problems solved by technology

[0016] In practical application, the above scheme has the following problems: the handover delay between eNodeBs in the LTE network is relatively large
[0017] The main reason for this situation is that the GW cannot control the bicast to the source eNodeB and the target eNodeB because there is no RRC context of the UE in the GW. Maintain the process of selecting candidate eNodeBs, so the selection process is complicated and the handover delay is large

Embodiment Construction

[0056] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0057] For the eNodeB and GW two-layer node structure of the LTE network, before handover between eNodeBs, the image of the RRC context of the UE is transferred to the GW, and a copy of the image is delivered to the adjacent eNodeB according to the cell where the UE is located, realizing Preprocessing of over-the-air assets before switching.

[0058] The UE handover method in the LTE network according to the first embodiment of the present invention is shown in FIG. 4 , wherein the UE moves from the adjacent cell C09 of the source eNodeB1 to the adjacent cell C08 of the target eNodeB3 through the adjacent cell C01 , as shown in FIG. 5 .

[0059] In step 401, the UE transmits service data with the source eNodeB1, and enters the adjacent cell C01 from the non-adjace...

Abstract

This invention discloses one long time progress network user device switch method, which comprises the following steps: according to whether or not near other encode, dividing the down area of encode into near and non near areas; when UE enters near area, establishing UE RRC message image in GW and establishing message copy in RRC near encode; if the results are to switch UE to near encode and then directly using the copy message to align wireless materials to fulfill switch.

Description

technical field [0001] The present invention relates to a long-term evolution network, in particular to a user equipment switching method in the long-term evolution network. Background technique [0002] Since the mobile communication technology entered the second generation of mobile communication (The Second Generation, "2G" for short) at the end of the 20th century, it has developed rapidly. However, with the increase in the number of users and the continuous improvement of the requirements for business types and performance, 2G gradually shows limitations in data transmission capabilities. Therefore, the third generation of mobile communication (The Third Generation, referred to as "3G") with stronger data transmission capability has entered a stage of rapid development, and the field of mobile communication is showing a trend of gradually transitioning from 2G to 3G. [0003] While the 3G system is gradually entering commercial use, the industry has already started res...
