Telecommunication system comprising subscriber connection units having independent routing ability
First Claim
1. A telecommunication system comprising:
- subscriber connection units having independent routing ability for a telecommunications network having an intelligent network structure, said telecommunications network including exchanges controlled by service control point means by means of predetermined operations constituting an intelligent network interface, and conveyed by protocols that are compatible with CCITT protocol No. 7;
each of the subscriber connection units being connected to an associated parent exchange via speech links and to said service control point means via a first No. 7 signalling link for controlling subscriber access to the associated parent exchange;
wherein the subscriber connection units are also connected to said service control point means via a second No. 7 signalling link conveying the intelligent network interface for the purpose of enabling said service control point means to control connections between subscribers connected to the same subscriber connection unit, connections between subscribers connected to different ones of said subscriber connection units, and connections from said subscriber connection units to a public switched network without requiring a speech link via the associated parent exchange.

Abstract
A cellular radiotelephone network including a connection unit having a conventional first No. 7 signalling point for providing conventional control of access to a parent exchange for subscribers connected to connection units by means of signalling messages in compliance with interface A as defined by a the Special Mobile Group (GSM) and a second No. 7 signalling point and No. 7 links to a signalling point of a service control point, where the links convey an "intelligent network interface" for enabling the control point to control connections established by one of the connection units between subscribers connected to that unit, or connections established directly to other connection units, or connections established to the public network without said connections requiring a link via the parent exchange of the units.

3. A telecommunication system comprising:
-
subscriber connection units having independent routing ability for a telecommunications network having an intelligent network structure and comprising a public switched network, said telecommunications network being controlled by service control point means by means of predetermined operations constituting an intelligent network interface, and conveyed by protocols that are compatible with CCITT protocol No. 7; each of the subscriber connection units being connected to said service control point means via a first No. 7 signalling link, and via a second No. 7 signalling link conveying the intelligent network interface; wherein the service control point means is directly connected to said public switched network via another No. 7 signalling link in compliance with said intelligent network interface.

9. A telecommunication system comprising:
-
subscriber connection units having independent routing ability for a telecommunications network having an intelligent network structure, said telecommunications network including exchanges controlled by service control point means by means of predetermined operations constituting an intelligent network interface, and conveyed by protocols that are compatible with CCITT protocol No. 7; each of the subscriber connection units being connected to an associated parent exchange via speech links and to said service control point means via a No. 7 signalling link for controlling subscriber access to the associated parent exchange and for conveying the intelligent network interface; wherein at least two parent exchanges are interconnected by a signalling link conveying an extended No. 7 signalling protocol for interchanging information required for remotely controlling two of said subscriber connection units respectively connected to said two parent exchanges.
