PURPOSE: A method for providing a PABX(private automatic branch exchange) function of a cell unit in a mobile communication switching system is provided to adapt a part of a PABX function which is used in a conventional voice switching system. CONSTITUTION: An access switching processor(ASP)(1) performs a control function for a call flow control, statistic measurement, collecting and report and billing measurement and report and includes a PABX subscriber database. An interconnection network subsystem(INS)(2) interconnects the internal apparatuses of a switch. A home location register(HLR)(3) is connected with the INS(2) and performs a mobile subscriber registration function. A central control sub-system(CCS)(4) is connected with the INS(2) and performs a concentrated operation and conserving function. The CCS(4) includes an OMP(Operation and Maintenance Processor)(5) which is a controller for controlling a system maintenance, a network management, a billing, a statistic, a database management, and an MMP(Man Machine Processor) which performs an operator connection function. |
