For the purposes of the present document, the terms and definitions defined in TR 21.905
and TS 22.146
and the following apply:
MBMS Service Announcement:
Mechanism to allow users to be informed about the MBMS user services available.
MBMS Bearer Service:
the service provided by the PS Domain to MBMS User Services to deliver IP multicast datagrams to multiple receivers using minimum network and radio resources.
MBMS User Service:
the MBMS service provided to the end user by means of the MBMS Bearer Service and possibly other capabilities.
MBMS Service Area:
MBMS over a Single Frequency Network:
Receive Only Mode:
The area within which data of a specific MBMS session are sent. Each individual MBMS session of an MBMS Bearer Service may be sent to a different MBMS Service Area. This MBMS Service Area is the same or a subset of the Multicast or Broadcast Service Area as defined in TS 22.146
. An MBMS Service Area smaller than the Multicast or Broadcast Service Area is typically used for localized services.
A UE configuration option that allows a UE to receive only eMBMS broadcast service without the need to access and register with the PLMN offering the eMBMS service. A UE configured to operate in Receive Only Mode receives MBMS service only on a standardised TMGI value range. The UE uses the acquired system information to receive MBMS broadcast. Use of Receive Only Mode does not require USIM for the UE.
Shared MBMS Network:
A network shared by multiple PLMNs that provides MBMS services. The Shared MBMS network consists of the following shared network elements: BM-SC(s) and MBMS-GW(s). The shared MBMS network may also include eNB(s), MCE(s), and shared MME(s) for MBMS operation.
