    摘要: A voice traffic gateway including: a voice traffic input, a voice traffic output, a first domain router, non-secure warning (NSW) tone application apparatus and a signalling filter. The input receives voice traffic including voice messages and signalling messages from a first traffic domain. The output delivers output voice messages and signalling messages to a second, different traffic domain. The first domain router routes voice messages to the NSW apparatus and routes signalling messages to the signalling filter. The NSW apparatus applies a NSW tone to a received voice message to form an output voice message. The signalling filter compares a feature of a received signalling message with a reference feature. The signalling filter will pass a signalling message if the signalling message feature is the same as the reference feature and will block a signalling message if the signalling message feature is not the same as the reference feature.

    摘要: The present invention discloses a method for an encrypted call, to resolve disadvantages of an encrypted call that is implemented relying on a KMC and network reconstruction, and reduce costs. The method includes: establishing, by a first terminal, a circuit switched call with a second terminal; determining, by the first terminal by using the circuit switched call, a key for performing an encrypted call with the second terminal; and performing, by the first terminal, an encrypted call with the second terminal by using the key. Embodiments of the present invention further provide a corresponding terminal.

    摘要: A system capable of normally connecting a call without degrading the security level in a mobile terminal network, even in cases when a call addressed to a set of user equipment (UE) arrives via the Internet or a home network. In ST 101, a femto base station (110) receives a packet addressed to a set of UE (100) via the Internet or a home network and, in ST 102, starts a paging procedure. In ST 103, the set of UE (100) establishes an RRC connection to the femto base station (110). In ST 104, the UE (100) transmits, to the femto base station (110), a paging response addressed to the SGSN (150). In ST 105, the femto base station (110) performs NAS verification. If the femto base station (110) detects the paging response to a paging request made by itself, the femto base station (110), in ST 107, changes the service type of the service request received from the UE (100) from the paging response to signaling.
