Service isolation and independent transmission system and method in power wireless private network

Abstract

The invention provides a service isolation and independent transmission system in a power wireless private network. The system comprises multiple terminals, a base station, a switch and a core network, a plurality of S1 port transmission links exist in the system. The base station is provided with a plurality of transmission boards, service information is wirelessly transmitted to the base stationfrom the terminal through an air interface and then is transmitted to the core network through the base station transmission boards and the switch in sequence, different service information independently corresponds to different transmission boards and S1 port transmission links, and the terminal is provided with different PLMNIDs corresponding to different services.

Description

technical field [0001] The invention relates to the technical field of data transmission, in particular to a system and method for business isolation and independent transmission in a power wireless private network. Background technique [0002] The power wireless private network system, based on LTE wireless communication technology, has the characteristics of wide coverage, low cost, strong security, and high reliability. It has been widely used in the power industry and supports power information collection, power distribution automation, load control, and precision control. , electric vehicle charging pile, voice intercom, intelligent inspection and other services. [0003] The power wireless private network system consists of core network EPC, S1 port transmission equipment, base station ENB, and terminals LCM, CPE, and handsets, among which LCM terminals support power consumption information collection services, and CPE supports power distribution, load control, precis...

Problems solved by technology

[0005] The present invention solves the problem that when various types of terminals use the same set of base stations and the same set of core network equipment when accessing the same cell, when various types of services are carried out at the same time, there may be mutual interference in the base station side transmission network and core network, and proposes a The system and method for business isolation and independent transmission in the electric power wireless private network, which distinguishes control services, such as load control services and precision control services, from other services, and transmits through different transmission boards and transmission network equipment during base station transmission. It is also independent and isolated from the core network equipment
