Title: Method for allocating radio resource in code division multiple access mobile communication system
Inventor: SEO CHANG GEUN
IPC: H04B7/02
Filed: 2001-10-19
Abstract: PURPOSE: A radio resource assigning method in a CDMA mobile communication system is provided to ensure providing an optimum service by selecting a cell with the best radio environment when a radio resource is requested to be reserved. CONSTITUTION: It is judged whether there is a cell transmitting a traffic data with an algorithm selecting a cell for transmitting a bust request message(S30). If there is no cell transmitting traffic data, a radio resource reservation is requested for a cell with the most powerful strength of a reported pilot signal(S31). If there is a cell transmitting traffic data, it is judged whether there are pilot signals with a better strength among the reported pilot signals than a pilot signal strength threshold value of a primary cell(S32). If there is no pilot signal of which strength is over threshold value, the current primary cell is maintained as it is(S33). If there are pilot signals of which strength is over threshold value, bust request messages are transferred to every cell which has those pilot signals, so that corresponding cells can perform a radio resource reservation(S34).
