Abstract: Systems and methods for user equipment (UE) for inter-device communication authorization and data sniffing in wireless communication systems are provided. A UE may communicate directly with another UE over a direct inter-device communication link when they are located in proximity. The UE may receive data sniffing related parameters corresponding to the inter-device communication link from a network entity, e.g. a mobile management entity (MME). The UE may store data exchanged over the inter-device communication link in a buffer and upload the stored data to a secure server in a network periodically or upon receiving a request from the network. Long term evolution (LTE) downlink or uplink radio resources may be used for the data exchange over the inter-device communication link.
