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.
