Abstract

The embodiment of the invention discloses a method and device for physically isolating services of a wireless private network, and the method comprises the steps: configuring subscription data for a terminal of the private network in advance, wherein the subscription data stipulates the corresponding gateway equipment when the terminal processes the private network service and establishes the communication connection with a private network server; based on this, after request information for establishing the communication connection of the private network service sent by a target terminal is received, directly finding the corresponding subscription data according to the identifier of the target terminal, and establishing the communication connection between the target terminal and the private network server according to the gateway specified in the subscription data. According to the method, when the communication connection of the private network is established through the subscription data, the gateways of different services for establishing the communication connection of the private network are physically isolated, so that the communication connection with the private network is established, the physical isolation of different services in the private network communication process is realized, and the security of data transmission is ensured.

Description

technical field [0001] The invention relates to the technical field of private network communication, in particular to a method and device for physically isolating services of a wireless private network. Background technique [0002] TD-LTE power wireless private network is a wireless communication system based on TD-LTE technology for smart grid distribution automation, power consumption information collection, and precise load control. Since the power system affects various industries of the national economy and the people's livelihood, higher requirements are put forward for the transmission security of the communication network. According to the safety protection management regulations of the power system, the general principle of safety protection of the power monitoring system is "safe partition, dedicated network, horizontal isolation, and vertical authentication"; The certification of the safety testing agency; the fine-control load system should form an independent...
