Key Technologies of 5G Proximity Services

With the development of mobile networks,the proximity services (ProSe) provide a greater implementation space for the improvement of user service quality,and also there are greater challenges at the same time.Based on the 3GPP proximity service standardization,this paper describes the key technologies of 5G proximity services.The authorization and direct discovery procedure based on ProSe are introduced,and then the technical characteristics and applicable scenarios for different ProSe relay communication modes are analyzed.Furthermore,some issues that need to be solved are investigated.Finally,the trends of technology development are analyzed from multiple perspectives,and the corresponding research suggestions are provided.This work could provide a reference for the development and deployment of 5G proximity service technologies.
