Problems solved by technology

[0004] (1) The bandwidth of the D channel is too narrow (only 16kbps in the case of 2B+D), and the upgrade process is slow
[0005] (2) In the case that the network management and the terminal need to span the entire dispatching communication network, since the intermediate node may not support ISDN services, it is impossible to transmit data through the D channel, and it is impossible to perform remote software upgrades on the dispatching terminal

Embodiment Construction

[0028] The preferred embodiments will be described in detail below in conjunction with the accompanying drawings. It should be emphasized that the following description is only exemplary and not intended to limit the scope of the invention and its application.

[0029] figure 1 It is a schematic diagram of the network structure to realize the remote software upgrade of the ISDN dispatching terminal across the dispatching communication network. figure 1 Among them, the network management system of the present invention selects any dispatching switch that can be managed in the dispatching communication network as a communication agent to realize the communication between the network management system and the ISDN dispatching terminal to be upgraded. The communication agent receives the information of the network management system and sends it to the dispatching communication network, and the dispatching communication network routes to the ISDN dispatching terminal to be upgrade...

Abstract

The invention discloses a method for realizing ISDN dispatching terminal long-distance software upgrade across dispatching communication networks in the technical field of the telephone dispatching communication. A network management system selects a dispatching exchanger as a communication agent, and initiates an emergent call to an ISDN dispatching terminal through the communication agent, the ISDN dispatching terminal can transmit the automatic response to the emergent call to the communication agent, thereby establishing a B channel connection from terminal to terminal, the communication agent can transmit a DTMF sequence which is defined in advanced to the ISDN dispatching terminal, the ISDN dispatching terminal can send out a long-distance upgrade starting response message to the communication agent, the communication agent can transmit the long-distance upgrade starting response message to the network management system, and the network management system can enter the software transmission state after affirming that the long-distance upgrade starting response message is correct, and upgrade software is released after being transmitted. The method improves the upgrade speed of software, and solves the problem of unattainable long-distance upgrade of the ISDN dispatching terminal caused by intermediate nodes which do not support ISDN services.

Description

technical field [0001] The invention belongs to the technical field of telephone dispatching communication, and in particular relates to a method for realizing remote software upgrading of an ISDN dispatching terminal across a dispatching communication network. Background technique [0002] In the telephone dispatching communication network, the dispatching service operation is mainly completed by calling the dispatching terminal through the network management system, and the dispatching terminal responds to the call of the network management system. The calls of the dispatching terminal of the network management system generally include emergency calls and ordinary calls, and of course there are other types of calls according to business needs. Among them, the emergency call is the highest-level call, and the dispatch terminal must automatically answer it immediately and unconditionally. In a dispatching communication network, especially a large-scale dispatching communica...
