First Claim
Patent Images
1. A signaling method for a first terminal to perform direct communication between terminals, the signaling method comprising:
- transmitting a first link establishment request message for establishing a direct communication link to a second terminal; and
receiving a link establishment response message for establishing a direct communication link from the second terminal,wherein the first link establishment response message comprises a first field indicating a flow that the second terminal will use.

Abstract
A signaling method for a terminal that performs direct communication between terminals terminal is disclosed. A transmitting terminal transmits a link establishment request message for establishing a link to a receiving terminal, and the receiving terminal transmits a link establishment response message responding to this message to the transmitting terminal. The link establishment request message includes a field indicating a flow to use if the receiving terminal acquires a token.
