US: SAE Traveler Info - LTE-V2X WSMP
Description
This solution is used within the U.S.. It combines standards associated with US: SAE Traveler Info with those for V–X: LTE–V2X WSMP. The US: SAE Traveler Info standards include upper–layer standards required to implement V2X traveler information flows. The V–X: LTE–V2X WSMP standards include lower–layer standards that support connectionless, near constant, ultra–low latency vehicle–to–any communications using the WAVE Short Messaging Protocol (WSMP) over 3GPP C–V2X in the 5.9GHz spectrum.

|---|---|---|---|
| Mgmt | 3GPP 24.301 | 3rd Generation Partnership Project;Technical Specification Group Radio Access Network; Non–Access–Stratum (NAS) protocol for Evolved Packet System (EPS); Stage 3 | The present document specifies the procedures used by the protocols for mobility management and session management between User Equipment (UE) and Mobility Management Entity (MME) in the Evolved Packet System (EPS). These protocols belong to the non–access stratum (NAS). The EPS Mobility Management (EMM) protocol defined in the present document provides procedures for the control of mobility when the User Equipment (UE) is using the Evolved UMTS Terrestrial Radio Access Network (E–UTRAN). The EMM protocol also provides control of security for the NAS protocols. The EPS Session Management (ESM) protocol defined in the present document provides procedures for the handling of EPS bearer contexts. Together with the bearer control provided by the access stratum, this protocol is used for the control of user plane bearers. |
