Content for TS 23.246 Word version: 18.0.0
1 Scope |R18| p. 7
The present document describes the stage 2 description (architectural solution and functionalities) for the MBMS Bearer Service, which includes, together with MBMS User Services defined in TS 26.346, all the elements necessary to realise the stage 1 requirements in TS 22.146 and TS 22.246. This document encompasses both GPRS and EPS.
The present document also includes considerations on the manner in which User Services should make use of the MBMS Bearer Service described herein. It should be noted that the specification of MBMS User Services in TS 26.346 takes precedence over User Service aspects described in this document.
The present document includes information applicable to network operators, service providers and manufacturers.

3 Definitions and abbreviations |R18| p. 8
3.1 Definitions p. 8
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:
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.
MBMS over a Single Frequency Network:
See TS 25.346.
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 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.
