45、P communications networks such as LTE are able to meet the requirements of critical communications some changes to the 3GPP standards are needed. The most critical have been proposed first and are called Group Communication System Enablers (GCSE) i.1 and Proximity Based Services (ProSE) i.2. These h
46、ave resulted in 3GPP Work Items for Release 12. There are likely to be further requirements. In order to benefit from the market scale available for public LTE and the attendant benefits such as lower cost, open standards, supplier choice, fast development of features and long term evolution of capa
47、bility the changes proposed to date have been kept to a minimum to improve the chances of them being implemented by manufacturers. This means that to deliver the full mission critical/critical communications functionality there has to be a Critical Communications Application (CCA) that sits above th
48、e LTE protocol. This application will need to provide the services required for critical communications i.3. (One of these services is push or press to talk, and NPSTC have recommended requirements for Public Safety in the US i.4. Outside of North America the PTT voice functionality of TETRA i.5, i.
49、6, i.12 and Tetrapol i.10 is taken as an assumed baseline on top of which further functionality appropriate to broadband is added. To avoid describing all the many standards a summary of this functionality and the exceptions, that is baseline functionality not needed in broadband are listed in clause 8). The application will need to have implementations in the infrastructure and in terminals with a standardized interface between them so that different vendors can be used. It is important that the standardization of the CCA sh
