摘要

The present invention discloses a method, device and system for interconnecting a trunking DMR/PDT and a conventional DMR/PDT, for realizing cross-system calls and SMS messages. The method comprises: when a DMR/PDT conventional terminal is online, receiving and storing, by an Internet gateway, terminal registration login information comprising a terminal number; forwarding the registration login information to a DMR/PDT trunking system and storing; receiving a call request comprising a terminal number of a called DMR/PDT conventional terminal, the call request being sent from a primary calling DMR/PDT trunking terminal to a DMR/PDT trunking system, and forwarded to the Internet gateway by the DMR/PDT trunking system after finding the registration login information according to the terminal number of the called DMR/PDT conventional terminal; and sending the call request to the called DMR/PDT conventional terminal so as to establish a call communication between the primary calling DMR/PDT trunking terminal and the called DMR/PDT conventional terminal.
