Lawful interception of triggered task states

Lawful interception, LI, of electronic communications includes receiving (301, 1), by a trigger function (135), a task request from an LI provisioning function, LIPF (122), the task request including a task identifier, ID. The TF (135) receives (320, 2) an indication of a protocol data unit, a PDU, session establishment applicable to the received request, and then triggers (330, 4)-comprising a POI task ID--each interception point applicable to the request, a POI (142). The TF (135) receives (340, 5) a task response indicating a state of the task at the triggered POI (142). The TF (135) reports (305, 6) to the LIPF (122) a TF task issue request indicating the status, a TF task ID, a POI task ID, and a network entity ID of the POI. 电子通信的合法拦截，LI，包括通过触发功能(135)接收(301，1)来自LI供应功能，LIPF(122)的任务请求，任务请求包括任务标识符，ID。TF(135)接收(320，2)适用于接收的请求的协议数据单元，PDU，会话建立的指示，然后触发(330，4)-包括POI任务ID--适用于请求的每个拦截点，POI(142)。TF(135)接收(340，5)指示经触发的POI(142)处的任务的状态的任务响应。TF(135)向LIPF(122)报告(305，6)指示状态的TF任务发出请求、TF任务ID、POI任务ID和POI的网络实体ID。
