example 1

[0049] SS and SG use the same even-numbered circuit to complete the call to the opposite end at the same time, and a circuit grab occurs between SS and SG. Among them, the signaling point code of SS is greater than the signaling point code of SG. In order to avoid the same competition of circuits, SS masters the even-numbered circuit. At this time, the CIC is an even number. Set to SLS so that CIC is a natural number. Send the reset SLS to the SG, and the SG selects the signaling link to the STP according to the SLS, ensuring that the SLS obtained by the signaling gateway is always balanced between 0 and 15 in the case of avoiding circuit competition. Make the distribution of signaling service from SG to STP balanced.

[0051] SS and SG use the same odd-numbered circuit to complete the call to the opposite end at the same time, and a circuit grab occurs between SS and SG. Moreover, the signaling point code of SS is greater than the signaling point code of SG. In order to avoid circuit competition, SS masters the odd-numbered circuit. At this time, the CIC is an even number, and the 4 bits from the second lowest to the fifth lowest of CIC Set to SLS so that CIC is a natural number. Send the reset SLS to the SG, and the SG selects the signaling link to the STP according to the SLS, ensuring that the SLS obtained by the signaling gateway is always balanced between 0 and 15 in the case of avoiding circuit competition. Make the distribution of signaling service from SG to STP balanced.

[0052] Through the above example, because the value of SLS is re-set, it is ensured that the SLS obtained by SG is always balanced between 0 and 15 when avoiding circuit competition, so that the distribution of s...

Abstract

The invention discloses a signaling link selection method and a system thereof, wherein, the method comprises the following steps: a signaling gateway receives a signaling link selection code from a soft switch entity, wherein, the signaling link selection code is four bits from the second low bit to the fifth low bit of a circuit identification code; and the signaling gateway selects the signaling link to a signaling transfer point according to the signaling link selection code. The signaling link selection method and the system thereof can ensure even allocation of signal services from the signaling gateway to the signaling transfer point.

Description

technical field [0001] The present invention relates to the communication field, in particular, the present invention relates to a signaling link selection method and system. Background technique [0002] When No. 7 (No. 7) signaling is used, the circuit between two switching offices can be defined as a bidirectional circuit, that is, any switching office can occupy this part of the circuit to complete the call to the opposite end office. However, since the delay time of signaling transmission may be long, there is a possibility of simultaneous circuit grabbing (two-way occupation). peer call. [0003] At present, most methods to solve the problem of simultaneous snatching of circuits adopt the master control identification method, that is, the circuit group is divided into two parts, which are respectively controlled by two terminal switching offices. If a certain switching office receives the initial address message of the same circuit after sending the initial address m...
