Problems solved by technology

And the CCR message stipulated in the current protocol can only conduct a continuity test for a single circuit
However, if a large-scale circuit (such as an office circuit and a trunk group circuit) is to be tested for continuity, a CCR message must be sent to each circuit in each E1 / T1, which will cause too much pressure on the system. , low efficiency; or use algorithm control to sample the circuit and propose a conduction test circuit for conduction test, but the conduction test conducted in this way is the result of sampling, and there will be deviation or inaccuracy

Embodiment Construction

[0024] The present invention adds some message types to the maintenance conduction test in the current ISUP / TUP protocol, so as to facilitate the group conduction test of large-scale circuits. For the convenience of narration later, it is explained as follows:

[0025] GCR: Group continuity check request message (Group continuity check request);

[0026] GCT: Group continuity message (Group continuity);

[0027] GCF: TUP group continuity check fail message (Group continuity check fail);

[0028] GRE: ISUP continuity check group release message (Group Release);

[0029]GRC: ISUP continuity check group release confirmation message (Group reset circuit);

[0030] GCL: TUP conduction test group release message (Group clear-forward signal);

[0031] GRL: TUP conduction check group release confirmation message (Group release-guard signal).

[0032] Combine below Figure 1 to Figure 4 Specific embodiments of the present invention will be further described.

[0033] Such as fig...

Abstract

A method for detecting group breakover in ISUP / TUP protocol includes launching breakover detection request to local bureau by maintenance station for starting up breakover detection of large scale circuit, sending a GCR to each E1 / T1 of opposite bureau by local bureau, assigning circuit scope of breakover detection in GCR, carrying out self-cycle on assigned circuit in GCR by opposite bureau, obtaining breakover detection result of opposite bureau and returning said result back to maintenance station by local bureau.

Description

technical field [0001] The present invention relates to a conduction test method in communication, more specifically, relates to a method for realizing group conduction in an integrated services digital network user part / telephone user part (ISDN User Part / Telephone User Part, ISUP / TUP) protocol method of inspection. Background technique [0002] During the communication process, the relay docking error (including mandarin duck line and loopback, etc.) in the inter-office TUP (Telephone User Part, telephone user part) and ISUP (ISDN User Part, integrated service digital network user part) will cause the in-call Crosstalk, single pass and double fail, etc. If the function of continuity test is added, the problem of relay error can be located quickly and conveniently, and it is not necessary to use self-loop, pull out E1, or test the specified circuit for checking. [0003] As the initiator of the continuity test, the transmitter and receiver (test tone transmitter and recei...
