An approach is provided for managing network resources and policies. A network resource manager receives an allocation request, over a radio network, for one or more network resources for joining one of a plurality of multicast groups, the one multicast group being associated with a quality of service (QoS) level. The network resource manager then determines whether the network can accommodate the allocation request and modifies the network to accommodate the allocation request based on the determination by modifying a local multicast service provider (LMSP) mapping list that associates, respectively, one or more LMSPs with the multicast groups.
