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.

Method and system for retrieving network addresses in hybrid telecommunication network

Communication network and method for providing communication facilities for a plurality of users. The communication network comprises an announcement generating element () for sending network related messages to any of the users. A further network element is connected to the announcement generating element, the further network element being arranged for determining a preferred language for a specific user () of the plurality of users, and sending network related messages to the specific user () in the preferred language.

Method and communication network for providing announcements in preferred language while roaming

A method and arrangement for providing a ring-back presentation to a calling terminal after receiving a call setup request from the calling terminal (A) for a first communication session () with a called terminal (B). A second packet-based communication session () is established with the calling terminal, independent of the first session, and pre-defined media content is provided as said ring-back presentation () to the calling terminal over the second session. Thereby, ring-back presentations to waiting callers can be selected from a great range of media types, including visual media. A calling user can also control the playout or display of the ring-back presentation irrespective of when the call is answered.

Method and arrangement for making a call-setup

In one aspect, the present invention provides a method for providing user information to a service provider. The method may include receiving a message including a communication device identifier; storing the communication device identifier with an identifier associated with a user of the communication device so that the communication device identifier is associated with the user identifier; transmitting a consent request message to the user; receiving a response to the consent request message, which response indicates that the user has provided the requested consent; and in response to receiving the response to the consent request message, transmitting a consent confirmation message to the service provider.

Systems and methods for enabling a service provider to obtain and use user information

A method and system enables a packet-switched data communication in a wireless communications system to be quickly and easily reestablished after interruption. The computer communications protocol that has been negotiated during the establishment of the packet-switched data communication may be saved upon interruption and later restored. In an exemplary embodiment, a wireless subscriber activates a call-waiting-type service along with an option to retain a packet-switched data communication. Thereafter, the subscriber may be engaged in a data communication on a packet data channel of the wireless communications system. Acceptance of a subsequent incoming, circuit-switched voice call causes the data packet session to be suspended, but the negotiated parameters of the computer communications protocol are saved. After the subscriber terminates the voice call, another data packet session is established with the saved parameters without needing to renegotiate the computer communications protocol parameters. Packet data applications that, have not timed-out may resume execution without reinitialization.

Retaining a data communication while responding to a paging notification

A method and apparatus for providing a call circuit connection between a mobile station and a remote application host is disclosed. Once a call circuit connection is initially established between a mobile station and remote application host to enable data to transfer therebetween, the call circuit connection is monitored for detection of an idle condition. Upon detection of the idle condition, identifying information for the call circuit connection is stored, and a first portion of the call circuit connection is disconnected while maintaining a second portion of the connection. Upon a request for reconnection of the call circuit connection, the first portion of the call circuit connection is reestablished with the second portion to enable continued data transfer.
