Method and apparatus for generating packet data network connection of user equipment

Abstract

The present disclosure relates to a communication method and system for converging a 5th-Generation (5G) communication system for supporting higher data rates beyond a 4th-Generation (4G) system with a technology for Internet of Things (IoT). The present disclosure may be applied to intelligent services based on the 5G communication technology and the IoT-related technology, such as smart home, smart building, smart city, smart car, connected car, health care, digital education, smart retail, security and safety services. The method includes transmitting a service authorization request message to a first network device, the first network drive including a proximity-based service (ProSe) function, and receiving a service authorization response message from the first network device. The first terminal is a relay terminal capable of performing a UE-to-network relay function.

What is claimed is: 
     
         1 . A method for a first terminal to transmit signals in a communication system, the method comprising:
 transmitting a service authorization request message to a network device associated with a proximity-based service (ProSe) function;   receiving a service authorization response message in response to the service authorization request message for authentication of the first terminal from the network device, the service authorization response message including a relay service code, validity time information related to a service authorization for a user equipment (UE)-to-network relay, and an access point name (APN) to be used for a packet data network (PDN) connection for a relay service code related service, the relay service code related service being provided for a second terminal through the first terminal; and   establishing the PDN connection for the UE-to-network relay based on the APN included in the service authorization response message,   wherein the first terminal is capable of performing a UE-to-network relay function, and   wherein the relay service code is used to identify the service provided by the UE-to-network relay
