Embodiment 1

[0057] This embodiment describes the process of handing over the user equipment to another cell according to the measurement report of the user equipment when the state of the home base station changes from the normal working state to the training state. The HeNB system is taken as an example below for description. Those skilled in the art should understand that the cell handover method in this example is applicable to the processing of user equipment by any CSG cell. image 3 The flow chart of handover for the UE of the present invention, such as image 3 As shown, the cell handover process in this example specifically includes the following steps:

[0058] Step 101, the home base station that is about to enter the training state selects the target cell according to the measurement report information of the user equipment, the signal quality of the target cell and the access situation of the user equipment (for a CSG cell, whether the UE reports an access indication) .

Embodiment 2

[0067] This embodiment describes the process of handing over the user equipment to another cell according to the measurement report of the user equipment when the state of the home base station changes from the normal working state to the training state. The following uses the HNB system as an example for description. Those skilled in the art should understand that the cell handover method in this example is applicable to the processing of user equipment by any CSG cell. Figure 4 The flow chart of performing relocation for the UE of the present invention, such as Figure 4 As shown, in this example, the UE relocation process specifically includes the following steps:

[0068] Step 201, the home base station selects a target cell according to the measurement report information of the user equipment, the signal quality of the target cell and the access status of the user equipment (for a CSG cell, whether the UE reports an access indication).

Embodiment 3

[0077] This embodiment describes the process of releasing the air interface connection of the user equipment when the state of the home base station changes from the normal working state to the training state. The HeNB system is taken as an example below for description. It should be noted that the processing flow in this example is applicable to processing of user equipment by any CSG cell. Figure 5 A flow chart of RRC connection release for the UE of the present invention, such as Figure 5 As shown, the process of releasing the RRC connection by the UE in the present invention specifically includes the following steps:

[0078] Step 301, the home base station sends a radio link release message to the user equipment accessing itself, and the message carries the reason for the release that the cell is in the training state; it may also carry time information that the cell is in the training state.

[0079] Step 302, after receiving the radio link release message, the user ...

Abstract

The present invention discloses a cell switching method, comprising: a home base station in a training state sends a switching request message or a relocation request message to the base station to which the target cell belongs; wherein, in the switching request message or the relocation request message Carrying the handover reason or relocation reason that the source cell is in the training state; the base station to which the target cell belongs determines whether to allow the UE to switch or relocate to the target cell, and returns a response message. The invention also discloses a cell switching system. The present invention supports the home base station to enter the training state for measurement, and when the cell is in the training state, switch or relocate the UEs accessing the cell to other cells that can be accessed, so that the current communication services of these UEs will not be affected. make an impact.

Description

technical field [0001] The present invention relates to a cell switching technology, in particular to a cell switching method and system when a home base station is in a training state. Background technique [0002] With the development of wireless communication technology, a concept of a home base station (HNB, Home NodeB) is introduced into the wireless communication system. Femtocells are small, low-power base stations that are 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. The advantages of femtocells are affordable, convenient, low power output, plug and play, etc. [0003] figure 1 It is a schematic diagram of the composition structure of the home base station system, such as figure 1 As shown, the home bas...
