Abstract: The invention relates to a method for controlling an explicit call transfer during a call in a telecommunications network comprising a switching node and an intelligent network, the intelligent network comprising a service control entity and a service switching entity. The service switching entity detects that explicit call transfer is invoked, and then sends a report to the service control entity indicating that explicit call transfer took place for the call. The report may comprise the call transfer number and a call transfer phase indicator indicating whether the call is active or in alerting state. The service control entity receives the report and will control the call transfer depending on the report.

Abstract: A method of and a system for establishing presence of a mobile station in at least one dedicated service area of a mobile telecommunications system providing service to a plurality of geographically spread service areas. A mobile station is triggered to provide location information relating to the presence of the mobile station at a location receiving service from a service area comprising the or each dedicated service area. Presence of the mobile station in the or each dedicated service area is established by comparing the location information provided by the mobile station and stored location information relating to the or each dedicated service area. If present in a dedicated service area, the mobile station automatically receives dedicated services to which the mobile unit is entitled to. Receipt of dedicated services is automatically indicated to a user of the mobile station.

Abstract: A technique for performing a service domain selection in a communications network having a default service domain and at least one alternative service domain is described. According to this technique, a switching to the alternative service domain involves the invocation of a supplementary service that is provided as a supplement to a basic service. A method implementation of this technique comprises steps of identifying a basic service type associated with a service request; determining if for at least one of an originating side and a terminating side of the service request the identified basic service type is linked with a subscription to the supplementary service of service domain switching; and invocating the supplementary service of service domain switching if a linking can be determined.

Abstract: The present invention relates to an overlay system between a GSM and IMS network, making use of virtual IMS subscriptions, which are temporary coupled with the identity of a non SIP compliant terminal, when the non SIP compliant terminal makes a call, is called or invokes an IMS service during the call, for the purpose of initiating a SIP session providing an IMS service to the terminal.

Abstract: A method of recording at least a part of a conversation between a plurality of conversation parties, wherein said conversation is enabled by establishing a call through a circuit switched telecommunications network. Said at least one part of said conversation is recorded in a data file using a recording system which is located in the network at a central location, and said recording is controlled by control signals provided to said recording system through a packet switched telecommunications network by at least one of said conversation parties. Said control signals identify said call for associating said control signals with said conversation. By providing the control through the packet network no DTMF tones need to interrupt the ongoing conversation to start and stop recording using access codes which also means that no monitoring circuit need continually be inserted in the voice path. Thus control of the recording is provided using an IP based interface rather than via the circuit switched path.

Abstract: The present invention is related to a method of handling a call between a plurality of users via a circuit switched telecommunications network.
