Abstract
Disclosed herein is a method performed by an IOPS application function, AF, to provide a group communication service. The method comprises: establishing an IOPS MBMS bearer, the IOPS MBMS bearer being an MBMS bearer within a MBSFN area served by one or more radio access nodes that are operating in an IOPS mode of operation; discovering one or more UEs via an IOPS discovery procedure; sending to the one or more UEs, an MBMS bearer announcement for the IOPS MBMS bearer.

A method performed by an Isolated Evolved Universal Terrestrial Radio Access Network Operations for Public Safety, IOPS, application function, AF, to provide a group communication service, the method comprising:
- establishing an IOPS Multicast-Broadcast Multimedia Services, MBMS, bearer, the IOPS MBMS bearer being an MBMS bearer within a Multicast-Broadcast Single-Frequency Network, MBSFN, area served by one or more radio access nodes that are operating in an IOPS mode of operation;
- discovering one or more User Equipments, UEs, via an IOPS discovery procedure;
- and
- sending, to the one or more UEs, an MBMS bearer announcement for the IOPS MBMS bearer.
A network node that implements an Isolated Evolved Universal Terrestrial Radio Access Network Operations for Public Safety, IOPS, application function, AF, for providing a group communication service, the network node adapted to:
- establishing an IOPS Multicast-Broadcast Multimedia Services, MBMS, bearer, the IOPS MBMS bearer being an MBMS bearer within a Multicast-Broadcast Single-Frequency Network, MBSFN, area served by one or more radio access nodes that are operating in an IOPS mode of operation;
- discovering one or more User Equipments, UEs, via an IOPS discovery procedure;
- and
- sending, to the one or more UEs, an MBMS bearer announcement for the IOPS MBMS bearer.
A method performed by User Equipment, UE, for group communication in an Isolated Evolved Universal Terrestrial Radio Access Network Operations for Public Safety, IOPS, system, the method comprising:
- performing an IOPS discovery procedure by which an IOPS application function, AF, discovers the UE;
- and
- receiving, from the IOPS AF, an Multicast-Broadcast Multimedia Services, MBMS, bearer announcement for an IOPS MBMS bearer, the IOPS MBMS bearer being an MBMS bearer within a Multicast-Broadcast Single-Frequency Network, MBSFN, area served by one or more radio access nodes that are operating in an IOPS mode of operation.
A User Equipment, UE, adapted to:
- performing an Isolated Evolved Universal Terrestrial Radio Access Network Operations for Public Safety, IOPS, discovery procedure by which an IOPS application function, AF, discovers the UE;
- and
- receiving, from the IOPS AF, an Multicast-Broadcast Multimedia Services, MBMS, bearer announcement for an IOPS MBMS bearer, the IOPS MBMS bearer being an MBMS bearer within a Multicast-Broadcast Single-Frequency Network, MBSFN, area served by one or more radio access nodes that are operating in an IOPS mode of operation.
