Embodiment Construction

[0031] The present invention will be further described below with reference to an embodiment of the present invention and the accompanying drawings.

[0032] figure 1 A schematic diagram of a specific embodiment of uplink scrambling code division in a wideband code division multiple access system planned for adopting the uplink scrambling code allocation method of the present invention. Such as figure 1 As shown, radio resource boards 1 to 8 in RNC2 are assigned radio resource board scrambling code sections, and the main control board is also assigned a shared pool of scrambling codes, and the RNC2 also obtains unallocated scrambling codes for the RNC The scrambling code information of the code segment.

[0033] figure 2 It is the basic step of the present invention. refer to figure 1 A specific example of scrambling code allocation, explaining the basic method steps of the present invention in detail. In step 10, the hierarchical distributed scrambling code allocation ...

Abstract

The present invention relates to a hierarchical distributed up-going scramble code divison multiple address system. Said invention comprehensively considers the up-going scramble code characteristics and its several factors of calculation, search, maintenance complexity and communication between plates so as to adopt the invented hierarchical distributed up-going scramble code distribution method, and make the main control plate and every wireless resource plate process up-going scramble code request of user terminal according to management level, and make every wireless resource plate process the scramble code in respective scramble code segment, so that it can reduce communication between main control plate and every wireless resource plate and can raise up-going scramble code distribution efficiency.

Description

technical field [0001] The invention relates to an uplink scrambling code allocation method used in a wideband code division multiple access communication system (WCDMA), in particular to a hierarchically distributed scrambling code allocation method in the wideband code division multiple access system. Background technique [0002] In the wideband code division multiple access (WCDMA) system, the network part is divided into two parts: the radio access network (RAN) and the core network (CN). The RAN is mainly composed of the base station (Node B) and the radio network controller (RNC). , each RNC needs to control multiple base stations (Node B), that is, the area under the jurisdiction of each RNC is divided into multiple cells, and each cell specifically implements the wireless access function of the user terminal (UE). [0003] In the WCDMA mobile communication system, the UE uses the uplink scrambling code in the uplink dedicated physical channel to distinguish users, a...
