    • Monitoring mobile telephone signaling carried by an ATM network to determine channels of interest. ATM cells of the ATM network are intercepted to monitor a UMTS terrestrial radio access network (UTRAN). The intercepted ATM cells are automatically analyzed to obtain a correspondence between a static Node B channel and a different private channel of the ATM network that is used to carry traffic to/from the Node B. The correspondence and other correspondences may be stored in a lookup table. A Node B's VPI.VCI, a VPI.VCI of a connected number may be extracted from a connection message. A call reference may be extracted from the connection message and stored in association with the correspondence. A connection breakdown message may be detected and, based on the release message matching the previously stored call reference, the stored correspondence that is associated with the call reference may be deleted.
    • 监控由ATM网络承载的移动电话信令,以确定感兴趣的信道。 拦截ATM网络的ATM信元以监视UMTS陆地无线接入网(UTRAN)。 被拦截的ATM信元被自动分析以获得静态节点B信道和用于向/从节点B携带业务的ATM网络的不同专用信道之间的对应关系。对应关系和其他对应可以存储在查找中 表。 可以从连接消息中提取节点B的VPI.VCI,连接号码的VPI.VCI。 可以从连接消息中提取呼叫参考并且与通信相关联地存储。 可以检测到连接故障消息,并且基于与先前存储的呼叫参考相匹配的释放消息,可以删除与呼叫参考相关联的存储的对应关系。
