Abstract
A method for communicating by a terminal, includes transmitting, to an MME, an attach request message including a public safety indication and/or a group communication indication; receiving, from the MME, an attach accept message including at least one type of information from among a ProSe identifier, a ProSe group identifier, and a ProSe group for performing a ProSe, ProSe-related functions of the terminal, and a proximity-related security key (ProSe key) The method further includes transmitting a ProSe registration request to a ProSe function server and receiving, from the ProSe function server, a ProSe registration response message pending authentication of the terminal.
Claims14
A method for performing a proximity based service (ProSe) communication by a first terminal in a wireless communication system, the method comprising:
- transmitting, to a core network node, a first message including group related information;
- receiving, from the core network node, a second message in response to the first message, the second message including a ProSe group key and a ProSe group ID;
- and
- transmitting, to at least one second terminal, data associated with the ProSe group ID, based on the ProSe group key and the ProSe group ID.
A first terminal for performing a proximity based service (ProSe) communication in a wireless communication system, the first terminal comprising:
- a transceiver;
- and
- a controller coupled with the transceiver and configured to control to:
- transmit, to a core network node, a first message including group related information,
- receive, from the core network node, a second message in response to the first message, the second message including a ProSe group key and a ProSe group ID, and
- transmit, to at least one second terminal, data associated with the ProSe group ID, based on the ProSe group key and the ProSe group ID.
