Method of routing calls in a communications system
First Claim
1. A method of routing calls which require intelligent network (IN) services between a pair of subscribers, at least one of which subscribers is a mobile network subscriber, the method including routing a call from a mobile network to an intelligent network via a first path to apply an IN service, and routing the call back to the mobile network via a second path or a third path, wherein calls routed via the second path are completed to the called party without further routing to the IN, and wherein for calls routed via the third path the mobile network determines whether a further routing of the calls to the IN is required prior to completion.

Abstract
A method of routing calls which require intelligent network (IN) services between a pair of subscribers, at least one of which subscribers is a mobile network subscriber. A mobile network (30) routes a call to an intelligent network (31) via a first path (32) to apply an IN service, and routes the call back to the mobile network via a second (33) or a third (34) path. Calls routed via the second path (33) are completed to the called party. Calls routed via the third path (34) may require further routing to the IN (31) prior to completion, such as where a different called party is involved or where a terminating IN service may be needed.

- 1. A method of routing calls which require intelligent network (IN) services between a pair of subscribers, at least one of which subscribers is a mobile network subscriber, the method including routing a call from a mobile network to an intelligent network via a first path to apply an IN service, and routing the call back to the mobile network via a second path or a third path, wherein calls routed via the second path are completed to the called party without further routing to the IN, and wherein for calls routed via the third path the mobile network determines whether a further routing of the calls to the IN is required prior to completion.
- 9. A communications system incorporating a mobile communications network and an intelligent network (IN), parts of the respective networks being linked by first, second and third paths, the first path being arranged to route calls to the IN for applying an IN service, and the second and third paths being arranged to route calls back to the mobile network, the second path carrying calls requiring completion to a called party, without further routing to the IN, and the third path carrying calls for which the mobile network determines whether further routing to the IN is required prior to completion.
- 11. A mobile communications network for use in a communications system incorporating the mobile communications network and an intelligent network (IN), the mobile communications network being arranged to link to the intelligent network by first, second and third paths, the first path being arranged to route calls to the IN for applying an IN service, and the second and third paths being arranged to receive calls back from the intelligent network, the second path carrying calls requiring completion to a called party, without further routing to the IN, and the third path carrying calls for which the mobile network determines whether further routing to the IN is required prior to completion.
- 13. An intelligent network (IN) for use in a communications system incorporating a mobile communications network and the intelligent network, the intelligent network being arranged to link to the mobile communications network by first, second and third paths, the first path being arranged to receive calls from the mobile network for applying an IN service, and the second and third paths being arranged to route calls back to the mobile network, the second path carrying calls requiring completion to a called party, without further routing to the IN, and the third path carrying calls for which the mobile network determines whether further routing to the IN is required prior to completion.
