Title: Simulation method for ce and svc quality measurement of mobile telecommunication system
Inventor: KANG JONG GU
IPC: H04B17/00
Filed: 2001-12-29
Abstract: PURPOSE: A simulation method for measuring a call resource quality of a mobile communication system is provided to test a call resource new board and detect a defective board after being serviced by using an auto page task, a virtual MSC(Mobile Switching Center) task and a transmission and reception task in an SVC(Selector Vocoder Controller). CONSTITUTION: A CCP(Call Control Processor) transmits a loopback mode start signal to a base station processor and an SVC, and, at the same time, generates an auto page task(1A) and a virtual MSC task(1B). The base station processor is switched to a virtual paging response mode and transmits a loopback mode signal to a CE(Channel Element). The SVC is switched to a D/S loopback mode and switches a transmission task(TX) to a Markov pattern transmission mode. The CCP generates a paging message corresponding to a given parameter and keeps transmitting it to the base station processor until a simulation is stopped. Then, the base station processor generates a virtual response message and reports it to the CCP. Upon receiving the virtual paging response message, the CCP transmits a call setup message to the virtual MSC task(1B), and the virtual MSC task(1B) transmits a call setup completion message to the CCP. Then, the CCP allocates a call resource in the SVC, and the base station processor also allocates a call resource in the CE. The SVC and the CE exchange a packet bearing the Markov pattern generated in the transmission task(TX). The transmission task(TX) compares the pattern of the packet received through a D/S loopback and the pattern of the packet transmitted to the CE and measures a quality.
