Abstract
Methods and apparatuses are described herein for proximity-based services (ProSe) service-based discovery. For example, a service utilizing-wireless transmit/receive unit (SU-WTRU) may be provisioned with a type of discovery on a per-service basis and a security credential on a per-service basis. The SU-WTRU may transmit () a PC5 discovery message with the type of discovery and a first security element that is generated based on the security credential. The WTRU may then receive (), from a service providing-wireless transmit/receive unit (SP-WTRU), a PC5 discovery response message that includes a second security element and a service identity associated with a service that the SP-WTRU provides. On a condition that the second security element is verified based on the provisioned security credential, the SU-WTRU may authorize () the SP-WTRU to establish a PC5 communication link with the SP-WTRU.
