Embodiment 600

[0053] Aiming at the above method, the present invention also proposes a corresponding device for automatically configuring physical cell identifiers in the evolved node eNodeB, such as Figure 6 As shown, an embodiment 600 of the device includes: a resource grouping information acquisition module 610, a resource configuration module 620, and a resource adjustment module 630; wherein:

[0054] The resource grouping information acquisition module 610 is used to obtain the grouping information of the PhyCellId through the network management system before the eNodeB performs automatic configuration of the physical cell identifier PhyCellId, and output the grouping information of the PhyCellId to the resource configuration module 620 and the resource adjustment module 630 respectively; the PhyCellId The grouping information includes at least dividing PhyCellIds with a total number of N into the first group and the second group in sequence;

[0055] The grouping information of PhyC...

Abstract

Disclosed are a physical area automatic identifier configuration method and a device; the method includes that: before automatically configuring the physical area identifier PhyCellId, N PhyCellIds are sequentially divided into a first group and a second group by a network administration system; during the PhyCellId automatic configuration of an evolution node eNodeB, the PhyCellId grouping information is acquired from the network administration system, and then a or multiple continuous PhyCellId configurations is or are selected from the first group of PhyCellId grouping information dispersedly according to the overall numbers of the eNodeB. The invention also provides a corresponding device according to the method. The invention not only prevents the conflict of physical area identifierresources of adjacent areas, but also compensates the insufficient physical area identifier resource used in the area timely.

Description

technical field [0001] The present invention relates to mobile communication system self-configuration and self-optimization technology, in particular to the self-configuration method for developing Universal Terrestrial Radio Access Network (E-UTRAN, Evolved Universal Terrestrial Radio Access Network) system in the Long Term Evolution (LTE, Long Term Evolution) project . Background technique [0002] E-UTRAN system, figure 1 As shown, it includes multiple evolved nodes eNodeB (Evolution NodeB, abbreviated as eNB) connected to each other through the X2 interface; the eNodeB in the E-UTRAN system communicates with the Mobility Management Entity (MME, Mobility Management Entity) or serving gateway through the S1 interface S-GW (Serving Gateway) connection. [0003] The E-UTRAN system supports self-configuration and self-optimization functions. The self-configuration function refers to the process in which the network system automatically obtains the necessary basic configur...
