摘要:
The present invention relates to a Lawful Intercept, LI, system and a method (S100) in a LI system comprising at least one Intercept Access Point, IAP, for intercepting communication traffic using User Datagram Protocol, UDP, and Transmission Control Protocol, TCP, packets in one or more communications networks. The IAP delivers said communication traffic as Communication Content, CC,to a Law Enforcement Agency, LEA, via a mediation functionality controlled by an administration functionality. The method comprises: - receiving (S110) CC as UDP and TCP; - storing (S120) UDP and TCP CC in a buffer arrangement; - forwarding (S130) TCP CC or UDP CC via a first CC handover interface HI3 or via a second CC handover interface HI4 separated from the first CC handover interface HI3 to the LEA. It is further provided a synchronization mechanism in order to retransmit all IP packets lost over the new interface HI4 and a buffer capacity process.
摘要(中):
本发明涉及一种LI系统中的合法侦听,系统和方法(S100),该系统包括用于使用用户数据报协议UDP和传输控制协议TCP拦截通信业务的至少一个拦截接入点IAP, 一个或多个通信网络中的分组。 IAP通过由管理功能控制的中介功能将通信流量作为通信内容CC提供给执法机构LEA。 该方法包括: - 接收(S110)CC作为UDP和TCP; - 在缓冲器布置中存储(S120)UDP和TCP CC; - 经由第一CC切换接口HI3或经由从第一CC切换接口HI3分离到LEA的第二CC切换接口HI4转发(S130)TCP CC或UDP CC。 还提供了一种同步机制,以便重新发送在新接口HI4上丢失的所有IP分组和缓冲器容量过程。
