Title: Method for Assigning Resources of Base Station Controller in the Mobile Communication System
Inventor: HAN JEONG HUI
IPC: H04W28/08
Filed: 2002-12-10
Abstract: PURPOSE: A method for assigning BSC(Base Station Controller) resources in a mobile communication system is provided to compare available resources that remain in each selector processor, and to assign available resources, which are not assigned, to the selector processors that can exhaust the unassigned available resources the most, thereby efficiently using selector resources. CONSTITUTION: When a mobile station attempts a call connection, a BSC confirms selector processor resources necessary for receiving a call(S1), and confirms unassigned resources every selector processor(S2). The BSC calculates a value that subtracts the number of CEs(Channel Elements) from the number of unassigned CEs in each selector processor(S3). The BSC confirms whether the unassigned CEs remain in a certain selector processor(S4). If so, the BSC searches a selector processor that has the smallest available selector resources(S5). The BSC assigns CEs as many as the number of the CEs which the call requires to the searched selector processor, and assigns the call(S6).
