1  Scope  p. 5

The present document specifies UE pre-configuration for multicast/broadcast services (MBS) in order to receive the data of multicast communication services and broadcast communication services as specified in TS 23.247.
The present document defines a management object (MO) that can be used to configure the UE with parameters related to reception of data of multicast communication services and broadcast communication services.
The MO is compatible with the OMA Device Management (DM) protocol specifications, version 1.2 and upwards, and is defined using the OMA DM device description framework (DDF) as described in the Enabler Release Definition OMA-ERELD-DM-V1_2 [8].
The MO consists of nodes and leaves conveying UE pre-configuration parameters used for multicast communication service and broadcast communication service selection and data reception.

4  General description  p. 6

A UE can support multicast and broadcast service (MBS) that is a point-to-multipoint service in which data is transmitted from a single source entity to multiple recipients either to all users in a broadcast service area (MBS broadcast communication), or to users in a multicast group (MBS multicast communication) as defined in TS 23.247. The UE may support pre-configuration of information for services using MBS.
If the UE is pre-configured with information related to services using MBS, the UE can discover and receive data for services by using the provisioned configuration.
The UE pre-configuration contains a list of PLMNs in which for each PLMN, the following information is configured:
  1. PLMN ID of the PLMN for which the configuration applies;
  2. RAN information based on NR-ARFCN on which the broadcast communication service is available;
  3. list of TMGI, on which the broadcast communication service is available, each associated with user service description (USD) information (see TS 26.517) for the MBS broadcast service. If TMGI and USD information for the MBS user service is configured for the PLMN selected for broadcast communication service, the UE uses the information configured therein to acquire the broadcast communication service;
  4. list of TMGI, on which the service announcement for broadcast communication service is available along with the associated USD information (see TS 26.517) for the MBS user service announcement service. If TMGI and USD information for MBS user service announcement is configured for a PLMN selected for broadcast communication service, the UE uses the information configured therein to acquire the service announcement for broadcast communication service; and
  5. default DNN and S-NSSAI pair for PDU sessions that can be used to join MBS multicast sessions (as specified in TS 24.501) for which no other information is available.
