Abstract: The present invention provides a method for Voice Handling via Dynamic Home Agents in a Network employing All-IP Architecture, and a system for handling voice call by using this method. The method comprises the following steps: when a first RCU is about to initiate voice call with a second RCU, a first agent address FA will be assigned to a corresponding mobile RCU by the RNC in which the mobile RCU resides; when the RCUs perform the voice call, corresponding Media Gateway (MG) assigns second agent address HA1 and HA2 to the first and second RCUs, respectively. Wherein both HA1 and HA2 are only valid during this call, and when the call is terminated or dropped, HA1 and HA2 will be released back to the pool of the IP addresses of the corresponding MG. The first and second RCUs implement the voice call based on the assigned first and second agent addresses. This method handles voice calls services via Dynamic Home Agents technique in MobileIP, so as to reduce the number of propagation of the IP header in communication channel in a wireless environment, and enhance system resources utilization efficiency.

Abstract translation: 本发明提供一种通过使用全IP架构的网络中的动态归属代理进行语音处理的方法，以及通过使用该方法来处理语音呼叫的系统。 该方法包括以下步骤：当第一RCU即将使用第二RCU发起语音呼叫时，由移动RCU所在的RNC将第一代理地址FA分配给对应的移动RCU; 当RCU执行语音呼叫时，相应的媒体网关（MG）分别将第二代理地址HA 1和HA 2分配给第一和第二RCU。 其中HA 1和HA 2只在此呼叫期间有效，当呼叫终止或丢弃时，HA 1和HA 2将被释放回相应MG的IP地址池。 第一和第二RCU基于所分配的第一和第二代理地址来实现语音呼叫。 该方法通过MobileIP中的动态归属代理技术处理语音呼叫业务，减少无线环境中通信信道中IP报文的传播次数，提高系统资源利用效率。
