Apparatus providing usage of mobile radio telephone terminals operating according to a first standard in a private telecommunications system operating according to a second standard

摘要

The mobile telephone connection has a digital cordless system with a mechanism (E1) allowing the use of a mobile phone in a first standard in a private telecommunications network and using a second standard, allowing connection to a private exchange. The radio transmitter-receiver (BTS) functions to the second cordless standard (DE) using an interface (C) which finds the position of the private network with respect to the mobile units and converts the signalling protocol from the first mobile telephone standard to the digital cordless standard.
