Title: Voice resource changing method for voice mailing system
Inventor: CHO YUN HO
IPC: H04M3/533
Filed: 2000-12-29
Abstract: PURPOSE: A voice resources replacement method for VMS(Voice Mailing System) is provided to double a common memory in VMS, so that the user does not make the operation of VMS interrupt when replacing the voice resources, thereby enhancing the reliability of the users to the service. CONSTITUTION: A call processing process approaches to a common memory segment produced by a manager and then outputs a guide voice necessary to a service to a designated time slot(S11). During the service, when it is necessary to change the guide voice(voice resources)(S12), the manager copies or stores the newly prepared voice file to a file system(S13) and informs the change of the voice file to the manager(S14). Thereafter, the manager produces a new common memory segment(S15), reads the voice file from the file system and then stores the file to the new common memory segment(S16). The call processing process uses the voice resources stored to the new segment(S17). The call processing process can approach two common memory segments.

Title: Method for management BSC processor in mobile communication system
Inventor: KIM SE YEON
IPC: H04W24/00
Filed: 2000-12-30
Abstract: PURPOSE: A method for managing BSC(Base Station Controller) processors in a mobile system is provided to prevent data loss and system performance deterioration, due to frequent node transfers, by setting a reference value for an error rate and transferring a relevant node only in case that the non-error rate of received data does not reach the reference value. CONSTITUTION: If node types and reference values for the non-error rate and CRC non-error rate of each node are reported from an upper board(S11), a lower board detects the total received packets inputted to a node and error packets among them(S13). The lower board computes the node's error rate as a percentage of the received error packets divided by the total received packets, and obtains a CRC error rate as a percentage of CRC error packets divided by the total received packets(S15). The lower board compares the obtained error rate and CRC error rate with the reported reference values(S17). If the obtained error rate and CRC error rate are smaller than the reported reference values, the lower board judges that the node is in a fault state, reports the state of the fault node to an upper block, and transfers the node(S19,S21).
