Methods, systems, and computer readable media for optimization of bearer resources for IMS roaming

摘要

Methods, systems, and computer readable media for optimization of bearer resources for IMS roaming are disclosed. According to one aspect a system for optimization of bearer resources for IMS roaming includes a home media resource function controller module (HMRFC) for managing local media resources and for selecting a visited media resource function controller module (VMRFC) to provide media resources to a home subscriber that is roaming in the visited network (“visiting subscriber”), and a VMRFC for managing media resources within the visited network and for providing media resources to the visiting subscriber in response to a request to provide media resources to the visiting subscriber.

主权项

1. A visited media resource function controller (VMRFC), comprising:
a processor; and a memory coupled to the processor, the memory including program instructions stored thereon that, upon execution by the processor, cause the VMRFC to:
manage media resources within a visited network, wherein a subscriber, when operating within a home network serviced by a home media resource function controller (HMRFC) becomes a home subscriber, and wherein the subscriber, when roaming in the visited network serviced by the VMRFC, becomes a visiting subscriber;receive a request from the HMRFC to provide the media resources to the visiting subscriber;provide the media resources to the visiting subscriber; andprovide information about the media resources to the HMRFC by sending an indication of a location of the information to the HMRFC.
