摘要： A node in an IMS network receives circuit switched signalling relating to a communication session sent from a terminal over a circuit switched access network, and also receives packet switched signalling relating to the communication session sent from the terminal over a packet switched access network. The packet switched signalling comprises an identifier, and the node uses the identifier to correlate the circuit switched signalling with the packet switched signalling. This allows terminals using ICS to send signalling over both packet switched and circuit switched access networks, and a receiving node to correlate those signals.

摘要： A system and method of providing an enhanced service in a telecommunications network. The system includes a telecommunications network utilizing a circuit switched and packet switched access capability. The system also includes a sending User Equipment (UE) originating a call to a receiving UE. The sending UE sends an indicator informing the network to wait for further call information before proceeding with a call request towards the receiving UE. The system also includes a control node for routing calls within the network. The control node combines the call information received from the sending UE with call routing information of the call for connecting the call with the receiving UE to form a call request to the receiving UE. Upon receiving the call request message by the receiving UE, the call is connected and a media path is established between the receiving UE and the sending UE.

摘要： A method and apparatus for managing access domain selection for a user device accessing an IP Multimedia Subsystem (IMS) network. A Call Session Control Function (CSCF) in the IMS network stores an access domain indicator associated with a user s contact address. The access domain indicator is associated with the user s contact address when the user registers with the IMS network. The CSCF sends the access domain indicator to an Access Domain Selection (ADS) function in the IMS network, the access domain indicator to be used by the ADS function in selecting an access domain. This allows the ADS function to select the correct access domain to use when sending messages to the user device.

摘要： The invention includes methods of using IMS Centralized Services, ICS, in the selection of a service domain relating to a call involving a User Equipment, UE, being served by a CS access network. In one aspect a method includes receiving a request from a routing node, such as a Mobile Switching Center, MSC, or a Gateway Mobile Switching Center, GMSC, for a service domain selection at a Service Control Point, SCPin the UE's IMS network (801). The SCP has a Service Domain Selection, SDS, function, which retrieves data relating to the UE from a Domain Selection function (802). Based on the retrieved data, the SDS selects either the IMS service domain or the CS service domain as the service domain for routing the call (803), and sends an indication of the selected service domain to the routing node (805). Other aspects include methods for domain selection at the originating and terminating sides of the call, and network entities configured to carry out the methods.

摘要： In a mobile network with a plurality of access networks (210, 220), a control node (110) which is controlling access of a user equipment (300) to that one of the access networks (210, 220) which is currently used by the user equipment (300) determines an access capability of the user equipment (300) in said access network (210, 220), e.g. support of voice communication over packet switched access. The control node (110) provides an indication of the determined access capability to a subscriber database (150) associated with the user equipment (300). The indication may then be retrieved from the subscriber database (150) and be used to control termination of a connection to the user equipment (300).

摘要： Exemplary methods for establishing an emergency call and an emergency call-back for a first User Equipment (UE) communicatively coupled to a visited Internet Protocol Multimedia Subsystem (IMS) network includes establishing an emergency call by the first UE sending an emergency call request to a Proxy Call Session Control Function (P-CSCF) in the visited IMS network. The methods further include providing, from the P-CSCF to a Serving CSCF (S-CSCF) in a home IMS network for the first UE, information comprising an indication that the emergency call has been performed and an equipment identifier of the first UE. The methods further include receiving, in the S-CSCF, an emergency call-back request from an emergency call-center, and using, in the S-CSCF, information comprised in the received emergency call-back and the information provided by the P-CSCF, to route the emergency call-back to the first UE and/or to a second UE.
