CDMA MOBILE COMMUNICATION SYSTEM, RADIO NETWORK CONTROLLER THEREFOR AND SCRAMBLING CODE ALLOCATION METHOD THEREFOR

摘要

PROBLEM TO BE SOLVED: To prevent the collision of a scrambling code generated for a certain terminal by a certain RNC and a scrambling code generated for the other terminal by the other RNC. SOLUTION: The low-order digit take-out part 221 of a data processor 22 takes out one non-allocated scrambling code low-order digit from a scrambling code low-order digit storage part 231 and a low-order digit allocation state write part 222 updates the storage of the allocation state of the code to an already allocated state. A high-order digit read part 223 reads the identification number of the present device from a scrambling code high-order digit storage part 232 and defines it as a scrambling code high-order digit. A high-order digit and low-order digit combining part 224 combines the scrambling code high-order digit and the scrambling code low-order digit to attain one scrambling code. COPYRIGHT: (C)2003,JPO
