48、 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 have resulted in 3GPP Work Items for Release 12. There are likely to be further requirements. In or
49、der 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 capability 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 the LTE protocol. This application will need
