Embodiment Construction

[0038] In order to solve the problem of automatic PCI allocation in a different-frequency scenario, an embodiment of the present invention provides a method for allocating cell identifiers. The embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0039] Such as image 3 As shown, a method for allocating cell identities, including:

[0040] 301. Obtain the information of the neighboring cell from the base station to which the direct neighboring cell of the newly activated cell belongs, and the information of the neighboring cell includes the physical cell identifier PCI;

[0041] In the embodiment of the present invention, the adjacent cell includes a cell with a different frequency from the newly activated cell, and the direct adjacent cell is a cell adjacent to or overlapping with the newly activated cell. If it is in the LTE system, the eNB where the newly activated cell is located Send a request to the eNB to...

Abstract

The invention discloses a method for allocating cell identity. The method comprises the following steps: acquiring the information of neighboring cells from a base station to which the direct neighboring cells of a newly activated cell belong, wherein the information of each neighboring cell comprises a physical cell identity (PCI), the neighboring cells comprises cells of which the frequency is different from that of the newly activated cell, the direct neighboring cells are cells adjacent to or overlapped with the newly activated cell; deleting the PCI of the neighboring cells of which frequency is same as that of the newly activated cell from the available physical cell identity set of the newly activated cell so as to obtain an new physical cell identity set; and selecting a PCI for the newly activated cell from the new physical cell identity list. The embodiment of the invention also provides a base station. The invention can be applied to automatic PCI allocation in multi-frequency scene.

Description

technical field [0001] The invention relates to the communication field, in particular to a method and a base station for distributing cell identifiers in mobile communication. Background technique [0002] Although the wireless performance of the 3G (The 3rd Generation, third generation) network has been greatly improved, from the perspective of commercial operation, operators require lower network construction and operating costs in order to provide users with lower prices. Network services to win the market. The key to reducing operating costs is to reduce the manual network planning and optimization process and expand network automation functions. Currently, the automatic allocation of PCI (Physical cell ID, physical cell ID) is the focus of wireless network system planning and optimization. [0003] The PCI automatic allocation is completed by the eNB, and its main purpose is to automatically allocate a suitable PCI for a cell newly introduced by the eNB (Evolved Node...
