Abstract: A method system and device are described as a solution for a called party that receives a call from a calling party that intends to be another calling party by means of A-number spoofing. The method comprises a verification request by the called party network during a call setup, made to the network of the assumed calling party. The address of the network of the assumed calling party is derived from the Calling Party Number CgPN identifier or Calling Line Identification CLI as provided by a call setup. When the CgPN is correctly provided, a verification request with the network where the calling party resides will yield status information that the calling party indeed has a call setup with the called party. When the A-number is spoofed, the verification will not yield status information that the calling party has a call setup with the called party.

Abstract: A method in a switching node of a circuit-switched telecommunications network comprises the steps of receiving from a packet-switched telecommunications network a request to establish a call towards a mobile station of the circuit-switched telecommunications network, and sending a request message to a location register for an instruction comprising one or more parameters for allowing the continuation of the establishment of the call to the mobile station. Upon receiving the one or more parameters from the location register, at least one of the one or more parameters is used to establish the call towards the mobile station. Furthermore, at least one of the one or more parameters is sent to the packet-switched telecommunications network. The at least one or more parameters sent to the packet-switched telecommunications network relates to the location of the mobile station. Therefore, entities within a packet-switched telecommunications network (e.g.

Abstract: A user equipment (UE) engages in a packet based call between a local party associated with the UE and a remote party. The UE establishes a control plane session of the call with a node of an Internet Protocol multimedia system (IPMS), and establishes a media session of the call managed by the IPMS. The UE determines a local endpoint for terminating an additional media session at the local party, and sends a first message of the control plane session to the IPMS. The first message indicates the local endpoint and indicates that management of the additional media session by the IPMS is not required. The UE receives a second message of the control plane session from the IPMS that indicates a remote endpoint for terminating the additional media session at the remote party. The UE configures the local endpoint for transfer of media with the indicated remote endpoint.

Abstract: A method for controlling congestion in a cell of a mobile communications network, the mobile communications network comprising a plurality of cells for communicating with user devices, comprises the steps of analyzing over a period of time the load in a group of neighboring cells, the group of neighboring cells forming a subset of the plurality of cells. A movement path of a cluster of user devices is estimated based on the analysis of the load in the group of neighboring cells. The size of one or more cells along the estimated movement path is adapted to control congestion in one or more cells. The reducing or increasing a cell size may be performed artificially by adjusting a threshold value at which one or more user devices should initiate handover to a different cell.
