Method and system for the determination of the PSCN parameter starting from the MFN parameter in a DECT cordless telephone system

摘要

A method and a system to obtain the Primary Receiver Scan Carrier Number (PSCN) starting from the data regarding the multiframe number (MFN) in a personal telephone system realized according to the DECT standard. The following steps are present calculating the minimum common multiple (m.c.m.) between the duration of a multiframe (160 ms) and the period necessary for the complete scanning of the frequencies by a radio fixed part (RFP); dividing this minimum common multiple (m.c.m.) by the duration of a multiframe and taking the quotient to obtain a periodicity value; waiting that the multiframe number (MFN) assumes a whole multiple value of the periodicity calculated as indicated above and beginning and the scanning starting from the known frequency (x) which is common to all fixed radio parts (FRP) to be synchronized.
