Disclosed are a UE configuration method, network side device and system for proximity awareness in the present invention, which are used to achieve the function of obtaining the service information by proximity awareness between terminals in a cellular communication system. The network side device configures the service ID of each service type to be sent by the transmission UE and the temporary device ID, and the network side device configures the service ID filtering template for the receiving UE according to the service types to be received by the receiving UE, and thus the configured transmission UE and the receiving UE can obtain the service information by proximity awareness.
