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

A method for a network device to transmit signals in a communication system, the method comprising:

• receiving a service authorization request message from a first terminal, the first terminal being capable of performing a user equipment (UE)-to-network relay function;
• and
• transmitting a service authorization response message in response to the service authorization request message for authentication of the first terminal to the first terminal, the service authorization response message including a relay service code, validity time information related to a service authorization for a 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,
• wherein the network device is associated with a proximity-based service (ProSe) function,
• wherein the PDN connection for the UE-to-network relay is established based on the APN included in the service authorization response message, and
• wherein the relay service code is used to identify the service provided by the UE-to-network relay function.

A first terminal configured to transmit signals in a communication system, the first terminal comprising:

• a transceiver;
• and
• a controller coupled with the transceiver and configured to:
• transmit a service authorization request message to a network device associated with a proximity-based service (ProSe) function,
• receive 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
• establish 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.

A network device configured to transmit signals in a communication system, the network device comprising:

• a transceiver;
• and
• a controller coupled with the transceiver and configured to control to:
• receive a service authorization request message from a first terminal, the first terminal being capable of performing a user equipment (UE)-to-network relay function, and
• transmit a service authorization response message in response to the service authorization request message for authentication of the first terminal to the first terminal, the service authorization response message including a relay service code, validity time information related to a service authorization for a 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,
• wherein the network device is associated with a proximity-based service (ProSe) function,
• wherein the PDN connection for the UE-to-network relay is established based on the APN included in the service authorization response message, and
• wherein the relay service code is used to identify the service provided by the UE-to-network relay function.
