7.12 MCData resource management (on-network)

7.12.1 General

Procedures for resource management are defined in subclause 10.11 of 3GPP TS 23.280 [5].

7.12.2 MCData services not handled by SIP core

MCData services that do not utilize the SIP core e.g. IP connectivity, cannot utilize the resource control functionality of the local outbound / inbound proxy. For these types of service, resource management is handled directly by the Rx interface from the MCData server to the PCRF, which is the MCData-5 reference point. The Rx interface is defined in 3GPP TS 29.214 [17].

The same types of resource management procedures as defined for SIP based services in 3GPP TS 23.280 [5] may also be applied for non SIP based services. That is:

– Request for unicast resources at session establishment (in this case service initiation);

– Request for modification of unicast resources; and

– Request for resources with shared priority.
