摘要:
Combinational networks may provide simultaneous connectivity over networks of different type between User Equipment of an A-party and B-party. A communication session, comprising a circuit switched call and one or more packet switched sessions, may be deployed simultaneously over different network types, in relation to the same User Equipment. The circuit switched call and the packet switched session may be correlated. As to retrieve the packet switched address of a circuit switched call partner, a retrieval for a packet switched network address is initialized by means of a circuit switched protocol over a circuit switched network. The address retrieval request is directed to the call partner or a network node that accomplishes the network address request.

Means and methodology for a SIP Invite receiving node to withdraw from the SIP session set-up loop by replying a redirect message to the SIP Invite sending node. The redirect message contains information for setting up alternative SIP session, said information being available in the SIP Invite receiving node. This information is needed by the SIP invite sending node for establishing an alternative SIP session as well as information needed by other nodes and applications further on in the SIP session set-up loop. The SIP Invite sending node is specially adapted to retrieve the information from the redirect message for establishing a new SIP session based on and containing the information from the redirect message. Several implementations are given for use in an IP Multimedia Subsystem of a telecommunication network.

A method and system for providing pre-emptive advice of charge messages (201) to users (5b-2) of a communications system (2), via mobile terminals or fixed terminals (5b-2). Each terminal has at least one physical and at least one functional connection in the communications system (2). The pre-emptive advice of charge messages (201) are based on historical usage (203), administrative (202) and operational (205) information in the communications system (2) and are sent to the user without user's request or initiation of the facility or service for which pre-emptive advice of charge is given.
摘要:
A method for a first node obtaining signalling information in a packet switched network. The method comprises the steps of the first node sending a first request message comprising a first request for collecting signalling information towards a second node comprised by the packet switched network; the first node receiving a first response message, the first response message comprising a signalling information added by the second node and the signalling information collected by the second node in response to the first request message.

The present invention provides a primary modem-router for enabling communication between user equipment and a home network. The primary modem-router comprises an access communication unit for enabling a connection with said home network, and a wireless communication unit. The primary modem-router further comprises a line monitoring unit for monitoring connection quality of the connection with the network. The line monitoring unit provides a connection failure signal upon detection of insufficient connection quality. A processing unit of the primary modem-router is arranged for receiving the connection failure signal, and for establishing a wireless connection with a further modem-router unit upon receipt of this signal. This enables communication with the home network. The invention further provides an access node and method of enabling communication with a network.

Induced answering method and system for CS-based telephony. A user terminal (5) for communication over a telecommunications network (3) includes at least a CS-telephony device (CSO) for processing CS-based telephony signals (CS1, CS2), the CS-based telephony signals being received and transmitted over a circuit switched bearer service. The user terminal is arranged for receiving an additional answer-related signal (PS1; CS3), the additional answer-related signal being associated with an incoming CS-alert signal (CS1) of an incoming call. Further, the user terminal is arranged for transmitting a response signal or CS-answer signal (CS2) over the circuit switched bearer service in response to information included in, or derived from, the additional answer-related signal.
摘要:
A method, apparatus and computer program in a telecommunication network (111, 112, 121) for routing a media stream from an IMS domain to an MSC (107, 107a) associated with a mobile station in a circuit switched domain of a PLMN (109), wherein a service control node (111, 112, 121) receives a first request for routing path data for routing said media stream to a logical address associated with said mobile station (110), and wherein said logical address is converted into a physical address of the mobile station (110) and subsequently converted into a physical address of the MSC (107, 107a). A service control node (111, 112, 121) in the IMS domain obtains the MSRN for the mobile station (110). The MSRN is used to route the call as an IMS call right up to the MSC (107, 107a). The service control node (111, 112, 121) may comprise a SIP-AS, an ENUM server or a Client Gateway.
摘要:
Combinational networks may provide simultaneous connectivity over networks of different type between terminals. Communication sessions on different network types such as Circuit switched and Packet switched, belonging to the same user equipment can be correlated. In case a communication session on a circuit switched network is halted by a supplementary service e.g. at an event such as acceptance of Call Hold, a communication session on a correlated packet switched network should be halted as well. A user equipment that detects the event sends a halt message to the circuit switched network and a message to the packet switched network or a session state manager node. The session state manager node either forwards the halt-message to the packet switched network, or sends a halt-message to the packet switched network when the packet switched network does not notify that a halt has occurred.

摘要:
The present invention is related to a method of handling a call between a plurality of users via a circuit switched telecommunications network. Each of said plurality of users comprises a terminal connected to say network for establishing said call. A call between said users are established, and call detail information for said call is registered on said network. At least one of said users provides user information to said network after said call has been established, and said user information comprises identification data for associating said user information with said call detail information. The invention further provides a terminal unit for use with the method of the present invention.
