Embodiment Construction

[0049] The embodiments of the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0050] The ANR establishment process is used to discover the adjacent relationship between cells, including the adjacent relationship between cells of the same base station and between cells of different base stations. The base station shall establish and maintain a neighboring cell relation table (namely NRT) for each serving cell. The base station should not only automatically detect surrounding neighbors and create new neighbor relationships, but also be able to delete inappropriate or outdated neighbor relationships.

[0051] The ANR function is mainly to maintain the mapping relationship information between frequency points of adjacent cells, PCI and ECGI (E-UTRAN Cell Global ID, cell global identity). by figure 2 For example, a UE (user terminal) detects a signal of Cell B within the service range of Cell (cell) A, and reports the ...

Abstract

The embodiment of the invention relates to a wireless communication technology, in particular to a survey information configuration method and system and a base station, which are used for solving the problem that a network side in the prior art can not carry out correct survey configuration on an HeNB (Home enhanced Node B) with a changed frequency point so that the inbound handover property is influenced. The method provided by the embodiment of the invention comprises the following steps: the base station determines frequency points, corresponding to an ECGI (E-UTRAN (Evolved Universal Terrestrial Radio Access Network) Cell Global Identifier), from a user terminal on the basis of the corresponding relationship between an updated ECGI and the frequency points, wherein the corresponding relationship between the updated ECGI and the frequency points is that the ECGI corresponds to the current frequency point of a femtocell; and the base station searches frequency points of the survey information which are not configured for the user terminal, from the determined frequency points and configures the survey information of the searched frequency points for the user terminal. By adopting the method provided by the embodiment of the invention, the accuracy of survey configuration for the HeNB with a changed frequency point can be improved, and the property of UE (User Equipment) forcarrying out inbound handover can be guaranteed.

Description

technical field [0001] The present invention relates to wireless communication technology, in particular to a method, system and base station for configuring measurement information. Background technique [0002] In the current LTE (Long Term Evolution, long-term evolution) R8 (version 8) protocol, a frequency point has 504 PCI (Physical cell ID, cell physical identification) can be allocated, but after the introduction of HeNB (Home eNodeB, home base station) , due to the small coverage and dense deployment of HeNBs, it is possible that PCIs at one frequency point in one or adjacent geographical locations may be repeated, that is, PCI conflicts may occur. PCI conflicts will have a certain impact on switching performance. A current solution to the shortage of PCI resources is: when a HeNB is powered off, its used PCI can be allocated to other HeNBs, and when the HeNB that is also powered off is powered on again, it can also choose to replace other PCIs. In addition, the sp...
