Call set-up and service invocation in telecommunications networks
First Claim
1. A switched mobile telecommunications network for providing communications connections between mobile network terminations, the network comprising:
- one or more mobile network terminations;
service processing means for providing services to or for the mobile network terminations;
the service processing means being initially accessible by service requests from the mobile network terminations by signaling connections, without establishing a communications connections with the mobile network terminations, wherein the service processing means includes means for enabling transmission of a message responsive to the service request to the network termination making the request when the service request is not granted; and
switching means controllable by the service processing means in order to establish a communications connection with the mobile network termination making a service request as part of the same transaction as the service request if a communications connection is required by the service requested by the mobile network termination.

Abstract
A telecommunications network is provided, including a switch configured such that a request from a first network termination to establish a communications link with a second network termination is directed to a service processor which directs the switch to establish the link. This enables the user terminal to direct service and call setup requests directly to the service processor, the switch not being involved with the call or service request until the service processor instructs it to participate, thereby minimizing the establishment and allocation of resources until it is clear that such resources are required. A call can therefore be validated before any communications links are established, thus potentially offering economies in the operation of the system.

- 5. A method of operating a switched mobile telecommunications network, the method being such that all service requests are initially directed from their originating network terminations by establishing a signaling connection to a service processing means, without establishment of a communications connection with a mobile network termination, and the service processing means provides services to a network termination over the signaling connections, the service processing means also controlling switching means to establish a communications connection with the network termination making a service request as part of the same transaction as the service request if a communications connection is required by the service requested and enabling transmission of a message responsive to the service request to the network termination making the request when the service request is not granted.

9. A switched mobile telecommunications network comprising:
-
one or more mobile network terminations;
a service processor providing services to or for said mobile network terminations, said service processor being initially accessible by service requests from the mobile network terminations by signaling connections, without requiring establishment of a communications connection with a mobile network terminations wherein the service processor includes means for enabling transmission of a message responsive to the service request to the network termination making the request when the service request is not granted; and
a switch controllable by said service processor to establish a communications connection with the mobile network termination making a service request as part of the same transaction as the service request if a communications connection is required by the service requested by the mobile network termination. - View Dependent Claims (10, 11, 12, 13)
one or more network service terminations selectively connectable to one or more of the mobile network terminations, under control of the service processor, to provide a communications connection.

14. A method of operating a switched mobile telecommunications network, including one or more mobile network terminations, comprising the steps of:
-
providing services to or for the mobile network terminations;
directing service requests from an originating network termination by establishing a signaling connection to a service processor without establishing a communications connection with a network termination;
enabling transmission of a message responsive to the service request to the network termination making the request when the service request is not granted; and
establishing a communications connection with the network termination which requested the service as part of the same transaction as the service request if a communications connection is required by the service requested by the network termination. - View Dependent Claims (15, 16, 17)
receiving an executable call request from a mobile network termination;
establishing a communications connection through a switch between the mobile network termination and a second network termination; and
establishing a communication request with a network service termination when a non-call service request or non-executable call request is received.

18. A switched mobile telecommunications network for providing communications connections between mobile network terminations, the network comprising:
-
one or more mobile network terminations;
service processing means for providing services to or for the mobile network terminations;
the service processing means being initially accessible by service requests from the mobile network terminations by signaling connections, without establishing a communications connections with the mobile network terminations, wherein the service processing means provides an indication to the network termination making the request that the service request is not granted; and
switching means controllable by the service processing means in order to establish a communications connection with the mobile network termination making a service request as part of the same transaction as the service request if a communications connection is required by the service requested by the mobile network termination.

19. A method of operating a switched mobile telecommunications network, including one or more mobile network terminations, comprising the steps of:
-
providing services to or for the mobile network terminations;
directing service requests from an originating network termination by establishing a signaling connection to a service processor without establishing a communications connection with a network termination;
providing an indication to the network termination making the request that the service request is not granted; and
establishing a communications connection with the network termination which requested the service as part of the same transaction as the service request if a communications connection is required by the service requested by the network termination.
