    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。

    IPC: H04L12/18

    Abstract: A communication system includes a decentralized, flat architecture where a plurality of base nodes each include controller capabilities so that a centralized base node such as a radio network controller is not required. At least one of the base nodes acts as an anchor node. The anchor node associates a time stamp with at least one packet and provides that to the plurality of base nodes. In one example, a multicast approach is used by a router device for distributing the packet and the associated time stamp to the plurality of base nodes. Each base node controls a timing of a transmission of the at least one packet over a wireless interface responsive to the associated time stamp.

    Abstract: A method for coordinating control of radio resources for multicast/broadcast services in distributed radio resource management. The method includes communicating information between a plurality of units having radio resource management responsibilities. The communicated information is related to coordinating at least one multicast/broadcast service provided by the plurality of units.

    Abstract: A real time data transmission method is used in a network in which a real time media gateway is provided to allow access to the internet backbone in addition to the usual GPRS specific gateway. The method involves changing the header in a real time data stream as it passes through the network so that it can pass directly to the real time gateway without passing through the GPRS specific gateway. This ensures that the data stream travels along a more direct route and shortens the headers used in the data stream in the process.
