Embodiment 1

[0061] This preferred embodiment 1 describes the operation process of handing over the user equipment to the home base station.

[0062] Figure 5 is an interactive flowchart of the handover method according to the preferred embodiment 1 of the present invention, such as Figure 5 As shown, the following steps S502 to S526 are included.

[0063] In step S502, the base station establishes an X2 connection with the peer HeNB.

[0064] Step S504, the base station obtains the CSG ID information of the cell included in the peer HeNB. The base station can maintain a CSG ID information table that records the cells contained in the peer HeNB that has established an X2 connection with it. For the convenience of description, this information table is named as the X2 connection peer CSG ID information table. In this table, each entry contains CSG ID information of a cell, and there are no duplicate entries, that is, only one entry is stored for cells with the same CSG ID information. ...

Embodiment 2

[0093] The preferred embodiment 2 is based on the preferred embodiment 1, and describes in detail the process of obtaining the UE access control judgment result table during the S1 interface handover operation process.

[0094] Image 6 is an interactive flowchart of the handover method according to the second preferred embodiment of the present invention, such as Image 6 As shown, the following step S602 to step 8608 are included.

[0095] In step S602, the MME receives a UE handover required message (Handover Required) sent by the source base station (H)eNB1.

[0096]In step S604, the MME constructs a UE access control decision result table for the UE performing the handover operation based on the X2 connection peer CSG ID information table maintained by the MME described in the first preferred embodiment of the handover operation target base station HeNB2.

[0097] In step S606, the MME carries the UE access control decision result table in the handover request message s...

Embodiment 3

[0101] This preferred embodiment 3 is based on the preferred embodiment 1, and describes in detail the process of obtaining the UE access control decision result table during the X2 interface handover operation process.

[0102] Figure 7 is an interactive flowchart of the handover method according to the third preferred embodiment of the present invention, such as Figure 7 As shown, the following steps S702 to S708 are included.

[0103] In step S702, the MME receives a route switching request (PATH SWITCH REQUEST) message sent by the target base station HeNB1.

[0104] In step S704, the MME constructs a UE access control decision result table for the UE performing the handover operation based on the X2 connection peer CSG ID information table maintained by the MME in the preferred embodiment 1 of the handover operation target base station HeNB2.

[0105] In step S706, the MME carries the UE access control decision result table in the route switching request message respon...

Abstract

The invention discloses a switching method and a switching system. The method includes that a source base station transmits opposite terminal base station information to a mobile management base entity, wherein the opposite terminal base station information is used for establishing X2 connection of the source base station with the mobile management base entity; the source base station receives an access control judgment result which is from the mobile management entity and corresponds to the opposite terminal base station information; and the source base station selects a target cell according to the access control judgment result and performs switching operation of user equipment for a target base station of the target cell. By the aid of the switching method and the switching system, signaling transmission in switching operation can be reduced, and switching operation success probability can be increased.

Description

technical field [0001] The present invention relates to the communication field, in particular, to a handover method and system. Background technique [0002] A home base station (Home eNB, HeNB for short) is a small, low-power base station deployed in indoor places such as homes and offices. The main role of the home base station is to provide users with higher service rates and reduce the cost of using high-rate services, and at the same time, to make up for the lack of coverage of existing distributed cellular wireless communication systems. [0003] figure 1 is a schematic diagram of a home base station network structure according to related technologies, such as figure 1 As shown, in the Advanced Long Term Evolution (LTE) system launched by the Third Generation Partnership Projects (Third Generation Partnership Projects, referred to as 3GPP), the core network elements include a mobile management entity (Mobile Management Entity, referred to as MME) and a Serving Gate...
