Method and device for generating third-level user adaptation layer dynamic routing table in soft switch gateway

Abstract

The invention provides a method for generating a third-level user adaptation layer dynamic routing table in a soft switch gateway, which comprises the following steps of: (a1) configuring a static routing table by a system database, wherein the static routing table contains all possible signaling couplings with the same number; (b1) establishing a first signaling coupling; (b2) updating all the signaling coupling arrangement in a dynamic routing table into the first signaling coupling; (c1) establishing a second signaling coupling; and (c2) reconstructing a dynamic routing table. Furthermore,after a signaling coupling is established each time, the dynamic routing table is reconstructed, and a dynamic routing table which uniformly distributed by each established signaling coupling is generated. The dynamic routing table has the advantages that: a dynamic list is reconstructed after a signaling coupling is successfully established, and the uniform distribution of each signaling coupling in the dynamic list is guaranteed by a vacancy replacing method, thereby avoiding the phenomenon that the dynamic list is in an unbalanced state when the process of establishing the signaling coupling is interrupted.

Description

technical field [0001] The invention relates to the field of communication and computer technology, in particular to a method and device for generating a dynamic routing table of a third-level user adaptation layer of a soft-switch gateway. Background technique [0002] In modern communication networks, the interconnection between different operators is involved. Judging from the current network development trend, the next generation network (NGN) with IP as the backbone network is the focus of each operator's construction. However, the PSTN network with SS7 as signaling bearer still plays an important role in network communication. Therefore, it involves the interconnection between networks of different bearer modes. The softswitch signaling gateway realizes the transmission of SS7 signaling on the IP network by converting the SS7 signaling on the PSTN side and the SIGTRAN adaptation layer protocol on the IP side, thereby achieving the intercommunication between the SS7 s...

Problems solved by technology

Once the process of establishing a signaling coupling is interrupted, it will inevitably lead to uneven distribution of signaling couplings in the dynamic routing table, and a large amount of traffic will be concentrated on the first signaling coupling

And the earlier the signaling coupling establishment process is interrupted, the greater the amount of traffic borne by the first signaling coupling will be. If only two signaling couplings are established, the first signaling coupling will bear most of the traffic. Traffic, which will inevitably lead to the collapse of the entire softswitch signaling gateway transmission system
