Method used

Because the routing state of a large amount of signaling points accessed by the transfer point is related to the state of the transfer point, so the routing information can be simplified by decomposing the routing table, so that No. 7 signaling network/IP signaling network No. 7 The normal routing management process of the third level can be managed by maintaining the routing tables of the first and second levels, and when the status of the transfer point changes, the updated routing entries are reduced. When the signaling point to the transit point fails, update the corresponding routing status in the first-level routing table. When the signaling point from the transit point to the transit point fails, the corresponding routing status in the secondary routing table is updated.

Abstract

The invention provides a signaling network routing management method. When a large quantity of signaling points are accessed through transfer points, the signaling points in the third grade function of the signaling network are decomposed into two grades through a routing table. The first grade routing table configures the routing from the signaling points to the transfer points. The second grade routing table configures the routing from the transfer points to the signaling points which are accessed through the transfer points. The method of the invention can simplify the routing maintenance process and reduce the item renewal quantity of the routing table and the burden of the signaling network management maintenance.

Test Example

[0038] Application example one

[0039] Figure 1 is a routing configuration in the prior art, A is a local signaling point, and B, C...N are connected to A through a transfer point. X does not pass through the transfer point and is directly connected to A.

[0040] The routing table representing the above route is:

[0041] DPC

[0042] Configure the route to B, C...N in Office A, and the message sent to B, C...N can directly find the route.

[0043] When the STP state changes, the routes of B, C...N need to be updated, and N routing table entries are updated.

[0044] Figure 2 shows the routing configuration using the method of the present invention. In the first-level routing table of Office A, no routes to B, C...N are configured, but only routes to STP are configured. Configure the routes from STP to B, C...N on the secondary routing table. Messages sent to X are routed and reachable, and are sent directly.

[0045] Level 1 routing table

[0046] DPC

[0047] Secondary routing table

[0048] DPC

[0049] Messages sent to B, C...N are not routed in the first-level routing table. Go to the second-level routing table to search, and find in the second-level routing table that there are routes from B, C...N to STP and are reachable. Then find the route of STP in the first-level routing table, there is a route to STP and reachable. Messages to B, C...N are sent directly to STP.

[0050] When the STP status changes, the routing status in the first-level routing table is directly updated, and only one routing table entry needs to be updated.

Test Example

[0051] Application example two

[0052] Fig. 3 adopts the routing configuration of multiple transfer points in the prior art. In Office A, the normal routes and alternate routes to C...N are respectively configured, and there are M×N routes in the first-level routing table. When a certain STP status changes, N routing table entries in the level 1 routing table need to be updated.

[0053] Fig. 4 uses the method of the present invention to configure the routing of multiple transit points. The first level routing table entry A of the signaling point A goes to transfer point 1...transfer point M, and the second level routing table is transfer point 1—transfer point M to C... ...N. When the status of a certain transit point changes, only one routing table entry in the level 1 routing table needs to be updated.

[0054] By decomposing the routing table into the first and second routing tables, the method of the present invention effectively solves the problem that when a large number of end offices access through signaling transfer points/IP signaling transfer points/signaling gateways in the signaling network When the status of the transfer point/IP signaling transfer point/signaling gateway changes, there are many routing update entries and complicated management problems. The method of the invention can be used to manage the routing of the signaling network by maintaining the primary and secondary routing tables, so as to achieve the purpose of maintaining a complete routing state. When a large number of signaling points are accessed through a transfer point, the maintenance process can be simplified. When the status of the transfer point changes, only the first-level routing table is updated, which reduces the number of routing table entries and reduces the management and maintenance of the signaling network. Burden.
