Content for TS 24.545 Word version: 18.5.0

1 Scope p. 10

The present document specifies the protocol aspects for the location management capability of SEAL to support vertical applications (e.g. V2X) over the 3GPP system.

The present document is applicable to the user equipment (UE) supporting the location management client functionality as described in TS 23.434, to the application server supporting the location management server functionality as described in TS 23.434 and to the application server supporting the vertical application server (VAL server) functionality as defined in the specific vertical application service (VAL service) specifications.
