  • Method and communication network for providing announcements in preferred language while roaming
    Patent number: 8756051
    Abstract: Communication network and method for providing communication facilities for a plurality of users. The communication network comprises an announcement generating element (14) 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 (10) of the plurality of users, and sending network related messages to the specific user (10) in the preferred language.

  • Retaining a data communication while responding to a paging notification
    Patent number: 6560239
    Abstract: 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.
