Problems solved by technology

[0006] In view of this, the purpose of the present invention is to provide a kind of distinction and processing method of two kinds of dialing failures of softswitch users, so that it can solve the dialing failures that the user has not dialed for a long time or the first number is dialed wrong in several existing standards. Under the situation, what information should be reported and the problem of how to deal with, the present invention has stipulated the type of reporting message for these two kinds of faults, and the value carried by the parameter ObservedEvents, ds and Method under two kinds of different faults in this message, makes The softswitch can distinguish between these two different faults and take corresponding actions

Embodiment Construction

[0027] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0028] First introduce the working mechanism of the present invention: as we all know, when the gateway adopts the H.248 protocol to collect the numbers dialed by the user, it uses the Digitmap to check, and can define three timers for receiving numbers. In the technical solution of the present invention, only relate to the utilization of initial dialing timer (T timer).

[0029] The basic process of number collection is: as soon as the user picks up the phone, the softswitch will send the digitmap, dial timer and other parameters to the gateway together. The phone number string dialed by the user matches the number plan set in the digit map, the user dials a wrong number, or any of the three timers times out, any of these three situations The gateway can be trig...

Abstract

A distinguishing and treating method for two dial faults of a soft-exchanger user comprises following steps: (1) after detecting device removal of an access user, a gateway reports the device removalaffair to the soft-exchanger by use of Notify messages; (2) the soft-exchanger sends the Notify messages to the gateway and directs the gateway to draw back the dial number from the user, and the Notify messages include number charts and timers for number drawing back; (3) when faults occurred upon user dialing are detected, the gateway sends the Notify messages to the soft-exchanger and reports the dial completion affair, the Notify messages takes following parameters: Observed Events: dd / ce, ds, wherein the Method adopts two different parameter values: 'FM' and 'PM' to distinguish the two faults of the user: not-dialing for a long time and wrong dialing of the first number; (4) The soft exchanger distinguishes the faults based on the empty number strands in the Notify messages and the values of the Method, and takes treating measures: sending the Notify messages to the gateway and directing the gateway to play busy tone for the user. This method can distinguish and treat the two dialfaults of the soft-exchanger user accurately and duly with high efficiency, simple performance and ensuring of operation service quality.

Description

technical field [0001] The present invention relates to a technology of how the gateway reports the abnormal fault and how the soft switch equipment takes corresponding processing measures after the abnormal fault occurs in the process of making a call by the user of the soft switch network. The invention relates to a method for distinguishing and dealing with dialing faults - the user has not dialed for a long time or dialed the wrong first number - and belongs to the field of softswitch network communication technology. Background technique [0002] The H.248 protocol is an interface protocol applied between the softswitch device and the gateway. In the ITU-T, IETF and Ministry of Information Industry standards of the H.248 protocol, it is stipulated that the gateway uses The digitmap method, when the gateway detects an event defined in the digitmap, it will report the "DigitMap Completion" event to the softswitch, where the parameter ds carries the matched number string, ...
