Abstract: The arrangement disclosed allows a user of a mobile telephone 11 to use intelligent network (IN) services specific to his home network, regardless of whether the network 12, 13, 14 to which he is currently connected can support the service. When the user makes an outgoing call attempt (step 1) the associated signalling is transmitted over a signalling channel. The mobile switching centre (MSC) 13 recognises a customer identity (encoded electronically in the call set-up signals ) and accesses the data relating to the user which is stored in a register 14. The data in the register 14 relating to the user 11 includes a marking identifying him as an IN served customer, causing the MSC 13 to halt the call process and send a signal (2), protocol, to the service control point (SCP) 15 in the user's home network. The SCP 15 then activates the user's service profile and as part of that profile recognises the need to retrieve additional information from the user 11, e.g.

Abstract: In a telephone network, e.g. a cellular radio system, after a transaction at the connection management layer CM has ended, for example at the end of a telephone call, the lower layers are not automatically released. If another connection is to be set up on ending of the current call, e.g. a voice message or `Call Completion to Busy Subscriber` arrangement, a flag F is set in the connection management system CM. The status of the flag F is used to determine if the signalling connection towards a termination B should be kept or released immediately. Depending on the status of the flag F different actions are taken in the network. The connection is maintained for a predetermined interval.
