    • In connection-oriented switching of packet data in known mobile communications systems, resources of the transmission path between the serving node (SGSN) and the radio network subsystem (RNS) and memory resources of the radio network subsystem are reserved unnecessarily due to the burst-like nature of packet data. Thus the transmission network's limited address space and the radio network subsystem's management resources are consumed. The invention concerns such connection management in a mobile communications system, which is suitable for packet-switched data transmission. The method according to the invention is characterized in that the logical connection between the serving node (SGSN) and the radio network subsystem (RNS) is released, so that the logical connection between the serving node (SGSN) and the mobile station (MS) remains, and the released logical connection is reconnected, when relaying of user data starts.
    • 在已知的移动通信系统中的分组数据的面向连接的交换中,服务节点(SGSN)和无线电网络子系统(RNS)之间的传输路径的资源以及无线电网络子系统的存储资源由于突发 - 像分组数据的性质。 因此,传输网络的有限地址空间和无线电网络子系统的管理资源被消耗。 本发明涉及适用于分组交换数据传输的移动通信系统中的这种连接管理。 根据本发明的方法的特征在于,服务节点(SGSN)和无线电网络子系统(RNS)之间的逻辑连接被释放,使得服务节点(SGSN)和移动台(MS)之间的逻辑连接 当中继用户数据启动时,释放的逻辑连接被重新连接。
