Abstract

A telecommunications network provides communications links between network terminations, and includes switches, two or more network terminations interconnectable by the switches to establish communications links between network terminations and a service control point for providing service to or for the network termination and/or the switches. The network determines the occurrence of a service request from a network termination and for the switches independent from a request for establishing a communications link between network terminations.

Claims

1. A telecommunications network comprising:

a plurality of physically interconnected nodes which can be functionally interconnected to support call traffic links;

a Basic Call State Model, (BCSM) in which the current state of a call in progress between two user terminals is stored and used to control call-related services;

additional means for assessing the occurrence of a non-call related service request associated with one of the nodes including a functional element triggerable between two states;

a first state where no service request is in process and second state where a service request is in process, the means for assessing being triggerable independently of the existence of a call traffic link so that the condition of the functional element controls the mode of operation of the network; and

means for transmitting the state of the assessing means associated with a network termination to the service control means, wherein;

the plurality of nodes includes a plurality of network terminations, there being provided switching means to provide functional interconnections between said terminations, and

the triggering of a means for assessing causes a service request to be transmitted from a node to a service control means.

2. A telecommunications network as in claim 1 wherein there is a plurality of means for assessing including means for identifying requests of differing types or classes of services.

3. A telecommunications network as in claim 1 wherein the services are non-call related services.

4. A telecommunications network as in claim 1 wherein the network includes a mobile radio network.

5. A telecommunications network as in claim 4 wherein the mobile radio network is a cellular radio network.
