Lawful interception for local selected IP traffic offload and local IP access performed at a non-core gateway


Abstract

Systems, methods, and instrumentalities are described to implement reporting of surveillance information associated with a device. A gateway device may intercept a communication associated with the device. The gateway device may route the communication such that the communication bypasses a core network. The gateway device may report information associated with the communication to a core network entity. The gateway device may receive a command message. The command message may include a request for a surveillance status of the device. The gateway device may send a response message. The response message may indicate a surveillance status of the device. The gateway device may receive an activate surveillance signal for the device. The gateway device may receive a deactivate surveillance signal for the device. Upon receiving the deactivate surveillance signal, the gateway device may stop further reporting.
