Description

The invention relates to a Chinese patent application filed on June 16, 2008 by the Chinese Patent Office, the application number is 200810110928.X, and the invention name is "a triggering method, system and device for switching" Priority is hereby incorporated by reference in its entirety. Technical field

The embodiments of the present invention relate to the field of communications technologies, and in particular, to a triggering method, system, and apparatus for handover. Background technique

The home base station is a cutting-edge technology and hot topic in the field of 3G (3rd Generation, 3rd generation mobile communication technology). The 3G home base station can seamlessly connect with the original network equipment of the operator, and fully utilize the existing broadband access resources of the user, and finally provide FMC (Fixed-Mobile Convergence, mobile and fixed network convergence) services. Through 3G home base stations, a large number of mobile services can be absorbed by indoor home base stations, which greatly reduces the number of operators' macro cells, saves operators a large amount of equipment investment costs and maintenance costs, and is the most economical indoor signal coverage technology.

Nowadays, user demand is becoming more and more diversified with the development of mobile communication technology. In order to adapt to diverse user needs, system equipment is also diversified. The home indoor coverage and enterprise-level internal coverage base stations and other limited applications are highly concerned. The network came into being. Such a network may be a home base station, a Home Cell, an Access Point, a Private Network, a Private Cell, etc., and a restricted network of certain frequency layers. Recently, 3GPP (3rd Generation Partnership Project) introduced the concept of CSG (Closed Subscriber Group). If a user signs up to the CSG or is added to the CSG by the owner of the CSG, Then, the user is allowed to normally camp in the CSG cell and apply for service; and the user who has not signed up and is not added to the CSG by the CSG owner cannot normally camp on the CSG cell, and cannot initiate the service.

In the 3G network, the access restrictions of the prior art on the private cell are implemented by the network rejection mode because the UE (User Equipment) does not know which private cells can be accessed. That is, regardless of whether the UE has access rights, the UE may initiate a location area update request to the network side, and the network side may identify whether the user has the right. For users with rights, the network side allows access. For users without rights, the network side rejects access.

In order to limit invalid access initiated by unprivileged users, along with the network rejection mode, the prior art also introduces a white name. The concept of a single, that is, the cells allowed to be accessed by the UE are listed as white lists and stored in the user card of the UE. However, when the user accesses the network for the first time, or the configuration of the whitelist of the UE is different from that of the network, users without rights will also initiate access to the network.

When the UE performs the cell handover, the prior art performs the handover decision according to the neighboring cell list according to the neighboring cell list and according to the event reported by the UE, that is, the handover decision is performed according to the quality of the downlink signal measured by the UE.

However, the existing standard stipulates that the number of neighboring cells included in the neighboring cell information sent by the radio network controller to the UE cannot exceed 32*3, that is, each type (same frequency, different frequency or different system) neighboring cell The maximum number is 32. Therefore, when the number of home base station cells of a type is large, and the number of the home base station cells exceeds 32, some home base station cells cannot send measurement control messages to the UE through the air interface, so the UEs that do not have the self-search capability cannot be triggered. The cell measurement makes it impossible for the UE that does not have the self-search capability to perform handover from the macro cell to the home base station cell. Summary of the invention

The embodiment of the invention provides a method, a system and a device for triggering a handover, so that a UE that does not have a self-search capability can perform handover from a macro cell to a home base station cell.
