摘要： In a radio or wireless access network, packets to be transmitted to a mobile radio are broadcast over a transport network to a set of associated radio access points, where each set of associated radio access points corresponds to a broadcast group. Each access point monitors packets broadcast to it broadcast group to determine if the access point should retrieve the packet. Rather than establishing packet tunnels to specific access points to transport packets to be transmitted to a mobile station through a transport network, those packets simply are broadcast over the transport network to the relevant broadcast group(s). Select diversity may be used where the mobile selects which access point transmits a particular packet to the mobile station. Alternatively, the network may decide which access point transmits a particular packet to the mobile station. This approach greatly facilitates cost-efficient and fast handovers of a mobile connection between access points in a wireless network.
摘要翻译：在无线电或无线接入网络中，要发送到移动无线电的分组通过传输网络广播到一组相关联的无线电接入点，其中每组相关联的无线电接入点对应于广播组。每个接入点监视广播组播广播组的数据包，以确定接入点是否应该检索数据包。不是将分组隧道建立到特定的接入点，而是通过传输网将传输的分组传输到移动台，而是简单地通过传输网络将广播到相关的广播组。可以在移动台选择哪个接入点向移动台发送特定分组的情况下使用选择分集。或者，网络可以决定哪个接入点向移动台发送特定分组。这种方法极大地促进了无线网络中的接入点之间的移动连接的成本效率和快速切换。

摘要： The present invention relates to methods and arrangements for reducing the time delay associated with the initialisation of a data transfer in a UMTS Radio Access Network. The Radio Network Controller, RNC, (102) connectable to a UMTS network and to a plurality of User Equipments, UEs, (108) wherein the UEs are capable of being in the states, URA PCH, CELL PCH, CELL FACH or CELL DCH, comprises means for handling a data transfer initiating message, means for introducing a delay reducing information in the data transfer initiating and means for transferring the UE from the URA PCH or the CELL PCH state directly to the CELL DCH state by means of the delay reducing information in the data transfer initiating message.
