Embodiment Construction

[0033] Fig. 2 is the basic steps of the present invention. Referring to the specific example of scrambling code assignment in FIG. 1 , the basic method steps of the present invention are explained in detail. In step 10, the hierarchical distributed scrambling code allocation for wideband code division multiple access system starts. In step 20, the scrambling code segment reserved for PRACH and PCPCH in network planning is 0---59999, and then the available uplink scrambling code segment allocated for RNC2 is the scrambling code segment with a scrambling code number of 60000---69999, which is the scrambling code segment with RNC2 The allocatable scrambling code segments allocated by the adjacent RNC1 jurisdiction area are the scrambling code segments with scrambling code numbers 70000-79999, so that the scrambling code segments allocated by each RNC do not overlap with each other. In step 40, RNC2 not only learns its own allocable scrambling code segment from the network planni...

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, ...
