This document specifies the functional architecture, procedures and information flows needed to support the Mission Critical Data (MCData) services. MCData is a suite of services which utilizes the common functional architecture defined in 3GPP TS 23.280 [5] to support MC services over LTE including the common services core.
MCData services suite consists of the following sub-services:
- short data service (SDS);
- file distribution (FD.
MCData features include:
- conversation management;
- transmission and reception control;
- communication release; and
- enhanced status.
The corresponding service requirements are defined in 3GPP TS 22.282 [3] and 3GPP TS 22.280 [2].
The present document is applicable primarily to MCData service using E-UTRAN access based on the EPC architecture defined in 3GPP TS 23.401 [4]. Certain application functions of the MCData service could also be supported via non- 3GPP access networks but no additional functionality is specified to support non-3GPP access.
The MCData service can be used for public safety applications and also for general commercial applications e.g. utility companies and railways.
