Abstract:
Systems, methods, and devices of the various embodiments enable evolved Multimedia Broadcast Multicast Service (“eMBMS”) network sharing, content sharing, and roaming. The various embodiments may enable Multimedia Broadcast Multicast Service (“MBMS”) service continuity across different public land mobile networks (“PLMNs”) by associating the same MBMS services providing identical content in different PLMNs with each other. In an embodiment, service discovery may be provisioned to a receiver device when or after the receiver device is attached to a PLMN. In an embodiment, content sharing across different PLMNs may be supported by a user service description indicating the different temporary mobile group identifiers (“TMGIs”) of the same service across different PLMNs. In another embodiment, content sharing across different PLMNs may be supported by a user service description indicating the same TMGI for the same service across different PLMNs. In an embodiment, MBMS keys may be shared across PLMNs.
