Content for TR 23.746 Word version: 14.0.0
1 Scope p. 6
The present document studies enhancements to the 3GPP system and UE procedures that are meant to cover essential functionality to enable new TV services by a 3GPP network. The scope of the work has three main components:
- A broadcast component where mechanisms to enable decoupling of content, MBMS service and MBMS transport, allowing the system to: offer eMBMS transport only, a shared eMBMS network between MNOs, broadcast only TV service to devices with no MNO subscription, will be studied.
- A unicast component, in which MNO subscription for TV service is required, where mechanisms for broadcast/unicast fall-back support, consumption-based switching between unicast/broadcast, and system enhancements for providing guaranteed QoS across large geographical areas will be studied.
- An MBMS user service exposure to 3rd party server, in which mechanisms in order to enable delivery of TV content based on the information provided by the 3rd party content/service providers, e.g. the expected broadcast area and time will be studied.

3 Definitions and abbreviations p. 7
3.1 Definitions p. 7
For the purposes of the present document, the terms and definitions given in TR 21.905, TS 22.101, and the following apply. A term defined in the present document takes precedence over the definition of the same term, if any, in TR 21.905.
Shared eMBMS network:
A network shared by multiple PLMNs that provides eMBMS services. The Shared eMBMS network consists of the following shared network elements: BM-SC, MBMS-GW, MCE, and MME. The shared eMBMS network may also include shared eNBs.
Receive Only Mode:
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 the standardised TMGI value range. The UE shall refrain from any Mobility Management or other signalling with the network offering eMBMS. The UE uses the acquired system information to receive eMBMS broadcast. Use of Receive Only Mode does not require USIM for the UE.
Receive Only Mode with independent unicast:
A UE configuration option that allows a UE to operate as Receive Only Mode (as defined above) for eMBMS broadcast service, and independently follows regular NAS/RRC procedures for unicast service with a PLMN. This mode of operation requires USIM and PLMN subscription to receive unicast service. No additional subscription or credentials are required to receive eMBMS broadcast service.
