Embodiment Construction

[0041] In order to make the object, technical solution and advantages of the present invention clearer, the following examples are listed and the present invention is further described in detail with reference to the accompanying drawings.

[0042] The embodiment takes the operation flow of the LTE system as an example, and the corresponding inventive method provides the same protection in the implementation of the 3G system, so details are not repeated here.

[0043] Image 6 It is the first implementation mode in which the macro base station initiates user handover, and the specific implementation steps are as follows:

[0044] Step 601, the user measures the wireless signal condition of the adjacent cell, and reports it to the currently serving macro base station in the form of a measurement report.

[0045] Step 602, the source macro base station finds that the signal of the cell where the current user is located is deteriorating and needs to be handed over to other base ...

Abstract

The invention discloses a switching optimization method and a switching optimization system, which are used for solving the technical problem that: in the process of user switching, a source base station has large time delay while switching to a home base station because the source base station cannot recognize which home base stations are user-subscribed home base stations. The user switching process is optimized under the condition of deployment of the home base station, a core network assists the source base station to execute the switching, and a mobility management entity of the core network assists the source base station to select an available home base station according to an optional switching base station list reported by the source base station. Therefore, the time delay for switching from the source base station to the home base station is reduced, and the switching efficiency is improved.

Description

technical field [0001] The present invention relates to the field of communication technologies, and in particular to a method and system for optimizing a user handover process under a home base station system structure. Background technique [0002] In order to maintain the competitiveness of the third-generation mobile communication system in the communication field, provide users with faster rate, lower delay, and more personalized mobile communication services, and at the same time reduce the operating costs of operators, 3GPP (3rd Generation Partnership Project , Third Generation Partnership Project) standard working group is working on the research of Evolved Packet System (EPS for short). figure 1 A schematic diagram showing the structure of an evolved packet domain system, such as figure 1 As shown, the entire EPS system is divided into two parts, the wireless access network and the core network. The core network includes a Home Subscriber Server (HSS for short), a...
