    Abstract: A method is provided of registering a mobile terminal in an area of overlapping cell coverage by first and second networks for wireless mobile telecommunications. The networks are of different types. The method comprises: storing an identifier of the mobile terminal; storing in a controller a first record of in which cell or group of cells the mobile terminal is located in the first network and a second record of in which cell or group of cells the mobile terminal is located in the second network; and providing the mobile terminal with information of both records and said identifier.

    Abstract: The present invention provides a method applicable to a mobile unit operating using Long Term Evolution (LTE) technology and having a single radio interface. The method controls a handover from a Voice over Internet Protocol (VoIP) call to a Circuit Switched (CS) call. The method comprises providing a CS call control message in a packet switched message, and routing the CS call control messages to a Mobile Switching Centre (MSC). Thereafter, a handover of the VoIP call to the CS call is initiated in response to receiving the call control message.

    Abstract translation: 本发明提供了适用于使用长期演进(LTE)技术并具有单个无线电接口的移动单元的方法。 该方法控制从网际协议语音(VoIP)呼叫到电路交换(CS)呼叫的切换。 该方法包括在分组交换消息中提供CS呼叫控制消息,并将CS呼叫控制消息路由到移动交换中心(MSC)。 之后,响应于接收到呼叫控制消息,发起VoIP呼叫到CS呼叫的切换。
