Description

Integrated Control and Management Method of GPS and PTIX using PTIX and Pilot Transmission Base Station System

The present invention provides an integrated control and management method for GPSR and PTXU using a pilot transmitter processor Global Positioning System Receiver Transmitter Execution (PGTX) incorporating a software block of a Global Positioning System Receiver (GPSR) and a Pilot Transmitter Unit (PTXU), and a pilot transmitting base station. The system relates to GPSR and PTXU, which integrates only the parts related to the function of eliminating unnecessary parts and outputting pilot signals in the conventional PCS (Personal Communication System) base station system to implement an economical and efficient pilot transmission system. The present invention relates to a method for integrated control and management of GPSR and PTXU using a PGTX incorporating a software block, and a pilot transmission base station system.

Conventional pilot transmission systems have been developed based on the existing Code Division Multiple Access (CDMA) PCS base station system configuration. The pilot transmitting base station is a system that outputs only a signal corresponding to a pilot channel of the CDMA method. There are many parts that are not used when the PCS base station system is used as it is. The PCS base station system includes various functions in the base transceiver subsystem control processor (BCP) because it must accommodate all the functions of various CDMA channels. Therefore, XCVR (Transceiver Rack) related functions are composed of TIP (Transceiver Interface Processor) and GPSR related functions are composed of software blocks distributed in BCP. XCVR related functions include transmission related functions and reception related functions. In the existing PCS base station system, GPSR related functions and XCVR related functions are various and complicated, so the software is divided into two blocks, which is functionally reduced like the pilot transmission base station system and is not economical to be applied to the small system. In particular, the pilot transmission base station system needs only a transmission function, no reception function, and GPSR or other processors do not need to be redundantly operated, so there are many unnecessary parts to use as a pilot transmission base station.

Therefore, the present invention was devised to solve the above problems, and it is possible to implement an economical and efficient pilot transmission system by integrating only the parts related to the function of eliminating unnecessary parts from the PCS base station system and outputting pilot signals. The purpose of the present invention is to provide a method for integrated control and management of GPSR and PTXU using a PGTX that integrates software blocks of GPSR and PTXU and a pilot transmission base station system.
