Access method, control device, system and equipment for remote backup switch

Abstract

The invention relates to an access method, control device, system and equipment for a remote backup switch. The method comprises the following steps of making a main switch respond to an access request of the terminal equipment after a first IP address of a central control system connected to the main switch is converted to a foreign IP address through NAT mapping when the access request of the terminal equipment is received; and making a standby switch respond to the access request of the terminal equipment after a second IP address of the central control system connected to the main switch is converted to the foreign IP address through NAT mapping when a preset trigger instruction is received. IP settings of the central control system of the main switch or the standby switch are automatically changed through an NAT router according to the received instruction, so that a purpose of making the main switch or the standby switch have the same unique IP address is realized when the main switch or the standby switch is foreign, and thus the interconnection between a remote backup environment and other standard systems is realized, and the user experience degree is promoted.

Description

[0001] 【Technical field】 [0002] The invention relates to the technical field of communication, in particular to an access method, a control device, a system and equipment of a remote backup switch. [0003] 【Background technique】 [0004] At present, when the PDT (Public Digital Trunking: police digital trunking standard) system backed up in different places is interconnected with other PDT standard systems, when other PDT standard systems access the central control and off-site backup environment of the PDT system backed up in different places, other PDT The standard system cannot identify the active and standby status of the off-site backup PDT system, and access will fail. Therefore, it is particularly necessary to provide a method for interconnecting the off-site backup PDT system with other PDT standard systems. [0005] 【Content of invention】 [0006] The present invention provides an access method, control device, system and equipment for remote backup switches, whic...
