Content for TS 24.548 Word version: 18.4.0

1 Scope p. 9

The present document specifies the protocol aspects for the network resource 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 network resource management client functionality as described in TS 23.434, to the application server supporting the network resource 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.

4 General description p. 11

Network resource management is a SEAL service that provides the network resource management related capabilities (e.g. unicast and multicast network resources) to one or more vertical applications. The present document enables a SEAL network resource management client (SNRM-C) and a VAL server that communicate with a SEAL network resource management server (SNRM-S).

The SNRM-S obtains and controls multicast resources from the underlying 3GPP network system via the BM-SC and controls unicast resources from the underlying 3GPP network system via the PCRF/PCF.
