LTE power wireless private network communication systems are widely adopted by the State Grid of China. In this paper, two improved security schemes for LTE power wireless private network communication system are proposed. Firstly, the security isolation scheme of wireless side network in LTE power wireless private network communication system is proposed. By setting two PLMNs in the power wireless communication system messages broadcast on the base station side, which corresponding to the production control area and management information area respectively, the two areas are identified to form a logical isolation. Secondly, by adding and assigning an access level to terminals of different services in the LTE power wireless private network communication system, the power service terminal realizes the access control of the network system, so as to achieve the access guarantee of some services under special conditions. These two improved schemes will be useful for the future in FDD system.
