Title: Method for management and duplexing of multi overhead channel
Inventor: KANG DAE GU
IPC: H04B7/26
Filed: 2000-12-27
Abstract: PURPOSE: A method for managing and dualizing multi-overhead channel is provided to dynamically operate information to overhead channels and report information related to the state change of the overhead channels to a mobile station, thereby normally operating the overhead channels and maintaining a continuous service state between the mobile station and a base station. CONSTITUTION: An overhead channel database is constructed(ST11). A BCM(BTS Configure Management) task and a state task are generated and driven(ST12). It is checked whether the state of overhead channels is changed(ST13). It not, the state task monitors the state of the overhead channels periodically(ST14). If changed, fields related to overhead channel dualization performance are searched(ST15). It is determined whether dualization should be performed(ST16). If dualization should be performed, a dualization routine of the overhead channels is performed(ST17). If not, the database of the overhead channels is rearranged(ST18). Configuration information is transmitted to the overhead channel(ST19). The changed item is reported to a mobile station(ST20).
