METHODS, APPARATUS, AND SYSTEMS FOR COMMUNICATIONS SECURITY WITH PROXIMITY SERVICES RELAY WTRU - A simplified explanation of the abstract

This abstract first appeared for US patent application 18033117 titled 'METHODS, APPARATUS, AND SYSTEMS FOR COMMUNICATIONS SECURITY WITH PROXIMITY SERVICES RELAY WTRU

Simplified Explanation

The patent application describes methods, apparatus, and systems for a wireless transmit receive unit (WTRU) to perform relay communications.

  • The WTRU receives a message indicating a security policy and maximum data rate for integrity protection supported by a remote WTRU.
  • The WTRU transmits a message to the network indicating the supported maximum data rate and a request for PDU session establishment.
  • The WTRU receives a message from the network indicating a second security policy for a second data link.
  • The WTRU establishes the first data link with the remote WTRU if the end-to-end security policy is compatible with the second security policy.
  • The end-to-end security policy is determined based on the second security policy and a UP security policy of the relay WTRU.


Original Abstract Submitted

Methods, apparatus, and systems for a wireless transmit receive unit (WTRU) performing relay communications are provided. A method may include receiving a first message indicating: (1) a first security policy associated with a first data link, and (2) a maximum data rate for integrity protection (MDRIP) supported by the remote WTRU; transmitting, to a network, a second message indicating: (1) an MDRIP supported by the remote WTRU or by the relay WTRU, and (2) a request for PDU session establishment; receiving, from the network, a third message indicating a second security policy for a second data link; and establishing the first data link with the remote WTRU on the condition that an end-to-end (e2e) security policy is compatible with the second security policy, wherein the e2e security policy is determined according to the second security policy and a UP security policy of the relay WTRU.
