Method for realizing group flowing test in ISUP/TUP protocol

Abstract

A method for realizing group continuity check in the ISUP / TUP protocol, comprising: (a) a maintenance station initiates a continuity check request to the local office, and starts the maintenance continuity check of large-scale circuits; (b) the local office sends each An E1 / T1 sends a group conduction check request message (GCR), and specifies the conduction check circuit range in the group conduction check request message; Carry out self-loop and conduct continuity test; (d) The local office obtains the continuity test result of the match and sends it back to the maintenance station. To implement the method provided by the present invention, in the conduction test of large-scale circuits, it is not necessary to send a conduction test request message to each circuit in each E1 / T1, and only need to specify in the group conduction test request message. The range of circuits to be tested for conduction is sufficient, and the efficiency of conduction test for large-scale circuits can be improved.

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...

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
