The LTE MBMS bearer service is used to support group communications of mission critical services through the GCSE enabler. The present document is targeted at facilitating interactions of group communications between mission critical applications and MBMS bearer services within the UE.

The present document defines abstract functionalities of application programming interface that allow mission critical applications to use MBMS capabilities without requiring access to implementation logic of MBMS operations. The API functionalities defined in the present document are platform and language independent. Related study was conducted in 3GPP TR 23.792 [7].
