    • A radio telecommunication system, and in particular an in-building system, comprises a number of basestations connected together by a local area network (LAN) at least one of the basestations (BS) is capable of receiving a control channel transmitted by one or more of the other basestations (BS) of the telecommunication systems, from which it derives frequency reference and time base synchronisation data to enable the basestation to correct the frequency and time offset of its own transmissions with respect to the other basestatations (BS) in the system. Also connected to the LAN is a controller (PC). The controller receives transmission measurement signals from each of the basestations (BS) and processes these transmission measurement signals to select radio frequency channels on which the basestations of the system should transmit to minimise interference with an external telecommunications system. The controller (PC) also receives transmission measurement signals from the basestations (BS) that are used to determine the power at which the basestations of the telecommunications system should transmit.
    • 无线电电信系统,特别是建筑内系统,包括通过局域网(LAN)连接在一起的多个基站,基站(BS)中的至少一个能够接收由一个或多个基站发送的控制信道 的电信系统的其他基站(BS),从其导出频率参考和时基同步数据,以使得基站能够相对于系统中的其他基站(BS)校正其自身传输的频率和时间偏移 。 还连接到LAN是一个控制器(PC)。 控制器从每个基站(BS)接收传输测量信号,并处理这些传输测量信号,以选择系统基站应发射的射频信道,以最小化对外部电信系统的干扰。 控制器(PC)还从基站(BS)接收用于确定电信系统的基站应发送的功率的传输测量信号。

    • A network element (405, 500) for supporting packet switched (PS) data communication over a data communication system (400), wherein the network element (405, 500) comprises packet inspection logic (519) arranged to inspect at least one received PS data packet that is being routed through the network element (405, 500). The packet inspection logic (519) is arranged to determine whether the inspected at least one received PS data packet that is being routed through the network element (405, 500) comprises a destination address for an Application Domain supported by the network element (405, 500). The network element (405, 500) further comprises routing logic (520) for routing, in response to a determination that the inspected at least one received PS data packet comprises a destination address for an Application Domain supported by the network element (405, 500), the at least one received PS data packet direct to an Application Domain logic layer (522).
    • 一种用于通过数据通信系统(400)支持分组交换(PS)数据通信的网络单元(405,500),其中网络单元(405,500)包括分组检查逻辑(519),其被配置为检查至少一个接收到的PS 数据分组正被路由通过网络元件(405,500)。 分组检查逻辑(519)被布置成确定正在被路由通过网络元件(405,500)的被检查的至少一个接收的PS数据分组是否包括网络元件(405,450)所支持的应用程序域的目的地地址, 500)。 网络元件(405,500)还包括路由逻辑(520),用于响应于确定检查的至少一个接收到的PS数据分组包括由网络元件(405,500)所支持的应用程序域的目的地地址 ),至少一个接收的PS数据分组指向应用领域逻辑层(522)。
