Method, apparatus and base station equipment for distributing scrambling code

Abstract

The embodiment of the invention discloses a scrambler distributing method. In the method, a first working scrambler is distributed, first voice service statistic data is collected when the first working scrambler works, and a first performance index is obtained according to the first voice service statistic data; a second working scrambler is distributed, second voice service statistic data are collected when the second working scrambler works, and a second performance index is obtained according to the second talking data; the distributed working scramblers are determined according to the first performance index and the second performance index. The embodiment of the invention also discloses a scrambler distributing device, a base station device and a communication system. According to the scrambler distributing method, the device, the base station device and the communication system provided by the embodiment, the probability that adjacent family base stations distribute the same working scrambler can be lowered, the switching success rate among the base stations of the families can be improved, UE network disconnections can be reduced, and the success rate of cell reselection and the application continuity when UE moves to the covering areas of the family base stations from macro-cell.

Description

technical field [0001] The present invention relates to communication technology, in particular to a method for allocating scrambling codes, a device for allocating scrambling codes and base station equipment. Background technique [0002] The third generation mobile communication system (3G) has been commercialized on a global scale, especially the WCDMA (Wideband Code Division Multiple Access) system, the number of users continues to increase, and the business volume increases month by month. Driven by the high-speed growth of business, the network ushers in the demand for high-speed growth, and puts forward higher requirements for network capacity, coverage and quality. For WCDMA technology, these three are closely related. In ensuring network capacity and quality Under the premise of improving network coverage, it can help operators improve operating income, so this is an important technical measure. Therefore, various forms of base stations have appeared one after anot...

However, the actual coverage of HNB2 overlaps with the adjacent HNB3. When the UE is in the overlapping coverage area, it will cause increased interference, affect the mobility management of the AP network, and fail to complete the handover. In severe cases, it will cause call drop and affect the success of the handover. rate, resulting in performance degradation of femtocell coverage network
