IMS Registration of a V2X Wireless Device

Abstract

Methods, apparatuses, systems, and computer-readable media for vehicle wireless device discovery are provided. A wireless device may receive a message related to vehicle-to-everything (V2X) multicast bearer coverage. After the V2X multicast bearer coverage is established between the wireless device and an internet protocol multimedia subsystem (IMS) network entity, one or more packets may be received via the V2X multicast bearer.

 one or more indicators for V2X multicast service capabilities based on the V2X multicast bearer coverage for the wireless device, and 
 one or more configuration parameters for reception by the wireless device from the IMS network entity via a V2X multicast bearer;

 one or more indicators for V2X multicast service capabilities based on the V2X multicast bearer coverage for the wireless device, and 
 one or more configuration parameters for reception by the wireless device from the IMS network entity via a V2X multicast bearer; 
   sending, to the IMS network entity, a third message confirming establishment of the V2X multicast bearer coverage; and   receiving, via the V2X multicast bearer, at least one packet.   
     
     
         10 . The non-transitory computer-readable medium of  claim 9 , wherein the second message further comprises one or more configuration parameters for receiving via a V2X broadcast bearer.
