Embodiment 1

[0030] An embodiment of the present invention provides a method for optimizing handover in an LTE system. Such as figure 2 As shown, the method includes the following steps:

[0031] 101. A first base station receives physical layer configuration information of a second base station.

[0032] Wherein, the physical layer configuration information is some physical layer parameters related to the handover process. For example, downlink system bandwidth, uplink system bandwidth, RACH (Random Access Channel, random access channel) configuration of the cell, and the like. For the definitions of these parameters, reference may be made to the definitions in the prior art, which will not be repeated here.

[0033] 102. The first base station generates difference information between the physical layer configuration information of the first base station and the second base station according to its own physical layer configuration information and the received physical layer configurat...

Embodiment 2

[0041] In this embodiment, taking the first handover manner as an example, a method for optimizing handover when user equipment is handed over from a source base station to a target base station is described. Such as image 3 As shown, its main processes include:

[0042] 201. The source base station sends a handover request message to the target base station. Wherein, the handover request message includes physical layer configuration information of the source base station.

[0043] 202. The target base station generates difference information between the physical layer configuration information of the source base station and the target base station.

[0044] In this step, the target base station generates difference information by comparing its own physical layer configuration information with the received physical layer configuration information of the source base station.

[0045] The difference information is the difference between the physical layer configuration infor...

Embodiment 3

[0052] In this embodiment, taking the first handover manner as an example, a method for optimizing handover when user equipment is handed over from a source base station to a target base station is described. Such as Figure 4 As shown, its main processes include:

[0053] 301. The source base station sends a handover request message to the target base station.

[0054] This step is consistent with the steps in the prior art, and the handover request message does not include the physical layer configuration information of the source base station.

[0055] 302. The target base station returns a handover request confirmation message to the source base station.

[0056] In this step, the physical layer configuration information of the target base station is included in the handover request confirmation message.

[0057] 303. The source base station generates difference information between the physical layer configuration information of the target base station and the source ba...

Abstract

The invention relates to the field of communication and discloses a method for optimizing switching processes. The method comprises the following steps: generating difference value information of physical layer configuration information of a source base station and the physical layer configuration information of a destination base station according to the physical layer configuration information of the source base station and the physical layer configuration information of the destination base station; and then sending the difference value information to user equipment, wherein the difference value information can be used when the user equipment is switched to the destination base station from the source base station. Meanwhile, the invention also discloses base station equipment. When the method and the base station equipment are adopted, the cost of null signaling messages can be saved, and the switching processes of the user equipment can be optimized.

Description

technical field [0001] The invention relates to the field of mobile communication, in particular to a method for optimizing switching and base station equipment. Background technique [0002] With the rapid development of communication technologies, 3GPP (3rd Generation Partnership Project, 3rd Generation Partnership Project) proposed a concept of an evolved network meeting future communication requirements, called LTE (Long Term Evolution, Long Term Evolution). [0003] The LTE system architecture consists of E-UTRAN (Evolved Universal Terrestrial Radio Access Network) and EPC (Evolved Packet Core, evolved packet core network). [0004] Depend on figure 1 As shown, the EPC mainly includes: MME (Mobility Management Entity, mobile management entity) and S-GW (Serving Gateway, serving gateway); E-UTRAN includes eNBs (Evolved Node B evolved base stations). Wherein, the eNBs are connected through the X2 interface, and the eNBs are connected with the EPC through the S1 interfac...
