Description

Method and device for reporting measurement results The present application claims to be filed on December 15, 2008 in the Chinese Patent Office, the application number is CN200810185818. X, the invention is entitled "A Method and Apparatus for Reporting Measurement Results" Priority is hereby incorporated by reference in its entirety. The present invention relates to the field of mobile communications, and in particular, to a method and apparatus for reporting measurement results. BACKGROUND OF THE INVENTION User demand has become more and more diversified with the development of mobile communication technologies, and system devices have also diversified in order to meet such demands. Some restricted networks have emerged, for example, Home NodeBs, home cells (Home) Cel l), etc., there are also restricted networks of certain frequency layers. For the scenario of a private network, the concept of a Closed Subscriber Group (CSG) has been introduced. If a user subscribes to a CSG user group or is added to a CSG user group by the owner of the CSG in the CSG network, the user is added. It is allowed to normally camp in the CSG cell and apply for services. From the perspective of the network, one CSG may contain one cell or multiple cells; users who have not signed up and are not added to the CSG by the CSG owner cannot reside in the CSG. The cell cannot initiate normal services.

In the LTE (Long Term Evolution) system, the terminal in the connected state triggers the CSG cell search through the fingerprint. When the searched CSG cell meets a threshold set by the system, the measurement result of the CSG cell is triggered. When measuring the adjacent intra-frequency cell, the terminal may acquire signals of multiple intra-frequency cells at the same time, which may include CSG cells and macro cells of the same frequency, and the CSG cells of the same frequency include the access and non-accessibility of the terminal. If the base station is cut into the CSG cell according to the measurement result, the base station can access the CSG cell according to the measurement result. If the signal quality of the incompatible CSG cell that is not accessible is better than the accessible cell, the UE will cause serious interference to the UE. In this case, the UE cannot initiate the service normally, which seriously affects the use experience of the terminal user. Summary of the invention
