Problems solved by technology

[0006] Although the current TD-LTE wireless network has the function of classifying different services by QoS (Quality of Service), it does not effectively isolate the services of different terminals. and other aspects are all mixed together, unable to meet the requirements of the Electric Regulatory Commission's Order No. 5 "horizontal isolation"

Embodiment Construction

[0028] The specific implementation manner of the electric TD-LTE wireless service system of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0029] refer to figure 1 as shown, figure 1 It is a schematic structural diagram of the electric TD-LTE wireless service system of the present invention, including: a production control subnet, a management information subnet and an LTE base station (that is, an evolved Node B, the name of a base station in LTE);

[0030] The production control subnet includes a first UE (User equipment, user equipment) terminal, a first service terminal, a first switch, a business master station in a security zone I, a business master station in a security zone II, a first EPC, a first operation and maintenance center;

[0031] The production control subnet includes a first UE terminal, a first service terminal, a first switch, a business master station in a safe zone I, a business master station ...

Abstract

The invention provides an electric power TD-LTE wireless service system. In a TD-LTE network, the service type Tag identifiers of UE terminals are increased, an LTE base station and an EPC, through distinguishing the service data types and the UE terminals with the different Tag identifiers, services needing physical partition are accessed to unified base stations, service data with different partitions and different types selects different physical resources, since the services needing the physical partition are accessed to different wireless sides, through physical frequency isolation, the different services are converged to different core networks, the two are physically completely independent, and access cannot be realized among subnets, such that network access, data processing and data transmission are isolated, and wireless resource access of partition services and key services is ensured; and whole network QoS configuration is that security I zone service data is provided with priority configuration authority of physical resources, such that it is ensured that high-priority service data is accessed in real time.

Description

technical field [0001] The invention relates to the technical field of electric power communication, in particular to an electric power TD-LTE wireless service system. Background technique [0002] Today's power communication research and successful practice have proved that the power wireless private network is an inevitable choice for the development of smart grid. TD-LTE (Time Division Long Term Evolution, Time Division Long Term Evolution) is an international 4G standard with independent intellectual property rights in my country. It has mature technology, industrial chain development, and a clear evolution path for technological development. It is the first choice for electric power wireless private network. The development of the electric power TD-LTE wireless private network needs strong support from national policies, and a dedicated frequency of 5MHz is allocated for the electric power wireless private network. The development of electric TD-LTE wireless private ne...
