Abstract: A call monitoring method for detecting an error in a Bearer-Independent Call Control (BICC) environment using an Internet Protocol (IP) as a bearer is provided, in which an MSC receives connection information about a called exchange from another MSC, requests IP resource allocation for configuring a termination to a Media GateWay (MGW) controlled by the MSC based on the received connection information about the called exchange, determines, upon receipt of a resource allocation failure message from the MGW, whether a cause of a resource allocation failure is an IP allocation error, and transmits the resource allocation failure message to a resource manager, if the cause of the resource allocation failure is an IP allocation error.

Abstract translation: 提供了一种用于检测使用因特网协议（IP）作为承载的承载独立呼叫控制（BICC）环境中的错误的呼叫监视方法，其中MSC从另一MSC接收关于被叫交换机的连接信息，请求IP资源 在接收到来自MGW的资源分配失败消息的情况下，基于接收到的被叫交换的连接信息，将由MSC控制的媒体网关（MGW）的终端的配置分配为资源分配失败的原因 IP分配错误，并且如果资源分配失败的原因是IP分配错误，则向资源管理器发送资源分配失败消息。
