Abstract

A communication system for organizations whose communications are assured via an international private telecommunication network and at least one other network enables a user of an accredited mobile radio terminal to pre-empt the setting up of a call via the private network from a node of the network to which it has access from a base station of a radio network. Each mobile radio terminal of the system can combine a code of the country in which it is located received from a base station with a node identifying indication that it stores and for sending dialling signals including an identification code of a node and a terminal number. The nodes of the private network enable a call to be set up to a terminal from the number of that terminal reaching the node with an identification code of that node.

Claims

1. A communication system for organizations wherein:

communications are assured partly by (1) a private telecommunication network, having international coverage, and by (2) at least one other telecommunication network, said private telecommunications network having private network nodes;

said communication system enables a user of an accredited mobile radio terminal to pre-empt the selection of at least part of a communication path by routing a call to a respective terminal through a respective one of said nodes of said private telecommunication network;

said accredited mobile radio terminal has access to said respective node of said private telecommunication network via a base transceiver station of a digital cellular radio network;

said accredited mobile radio terminal comprises;

means for storing coded indications individually identifying at least one of said nodes of said private telecommunications network,

means for combining an identification code, representing a geographical area in which said accredited mobile radio terminal is located, with at least one of said coded indications, to produce a combined code, and

means for enabling said mobile radio terminal to transmit address information, said address information comprising;

a private network node identification code, and

a terminal number of said respective terminal; and

said private network nodes comprise means for enabling said call to be placed to said respective terminal from said terminal number reaching said node with said identification code of that node.

2. A mobile radio terminal for use in a communication system of an organization, wherein:

communications are assured partly (1) by a private telecommunication network, having international coverage and (2) at least one other telecommunication network, said private telecommunication network having private network nodes;

said private telecommunication network and said other telecommunication network both enable an accredited mobile radio terminal user to select at least a part of a communication path, by routing a call to a respective terminal through a respective node of said private telecommunication network;

said accredited mobile radio terminal has access to said respective node of said private telecommunication network via a base transceiver station of a digital cellular radio network; and

said mobile radio terminal comprises;

means for storing coded indications individually identifying at least one of said private network nodes,

means for combining an identification code, representing a geographical area in which said mobile radio terminal is located, with one of said coded indications, and

means for enabling said mobile radio terminal to generate and transmit signals, wherein said signals include;

an identification code for one of said private network nodes, and

a terminal number of said respective terminal.

3. The mobile radio terminal of claim 2 further comprising a memory for storing therein said coded indications, wherein said coded indications identify said private network nodes in various geographical areas.

4. The mobile radio terminal of claim 2, further comprising a subscriber identification module, storing therein said coded indications, wherein said coded indications identify said private network nodes in various geographical areas.

5. The mobile radio terminal of claim 2, wherein said terminal is of the Global System for Mobiles (GSM) or Digital Enhanced Cordless Telecommunications (DECT) type.
