Background technology
Communication network except business transferring information, can also between communication equipment transfer control signal, such as, take request, releasing request, equipment busy-idle condition and called number etc.The network transmitting above-mentioned control signal is called signaling network, mainly comprises SP (Signaling Point, signalling point), STP (Signaling TransferPoint, Signalling Transfer Point) and signaling link.
Wherein, signalling point is originating point or the destination of signaling message, can be the various exchanges with No.7 signaling capability, such as, and telephone call office, Circuit-switched data handing-over office and Integrated Digital Services handing-over office; Also can be various Te Fu center, such as, Operation Centre, administrative center, maintenance centre and service control point etc.STP is when collimating connection work, is responsible for the signal switching center signaling message that a signaling link receives being forwarded to another signaling link.Signaling link is the most basic element of character connecting signalling point in signaling network, is made up of the I and II of No.7 signaling capability.Current signaling link has the analogue signalling link of 4.8kb/s, the digital signalling link of 64kb/s and 2Mb/s etc. multiple.
Signaling network can be divided into stepless signaling network and classification signaling network two class by the grade of network configuration, and wherein, stepless signaling network is the signaling network not introducing Signalling Transfer Point.In non-hierarchical network, adopt associated mode between signalling point, all signalling points are all in same rating.Stepless signaling network is relatively simple for structure, but signalling route is fewer, and the signaling will passed through in Signaling Relay is counted often, and when the quantity of signaling is larger, the signaling link quantity that interoffice connects obviously increases.Classification signaling network is also horizontal mipmap signaling network, is the signaling network introducing Signalling Transfer Point, comprises the secondary signaling network with one-level Signalling Transfer Point, and have three grades of signaling networks of secondary Signalling Transfer Point.Wherein, first order Signalling Transfer Point is called HSTP (High SignalingTransfer Point, HSTP High Signaling Transport Point) or main Signalling Transfer Point, second level Signalling Transfer Point is called LSTP (Low Signaling Transfer Point, Low Level Signaling Transfer Point LSTP) or secondary Signalling Transfer Point.The signaling message that each signalling point in classification signaling network sends generally needs the switching through one or more levels Signalling Transfer Point.In existing data routing system, LSTP and HSTP is disposed respectively in each area, thus realizes trans-regional signalling interworking,
Realizing in process of the present invention, inventor finds prior art, and at least there are the following problems:
The user data of the whole network is divided into polylith region by existing data routing system, limits the flexible access to user data, causes the complex situations being difficult to data syn-chronization between each data source.For a data access operation, need repeatedly route, the repeating process ability final arrival object equipment through multistage STP system, bring larger signaling delay expense, the repeatedly repeating process of equipment room too increases the risk that signaling sends unsuccessfully (makeing mistakes), and signalling efficiency is lower.Because HSTP/LSTP needs route and the forwarding of the signaling within the scope of responsible the whole province/city, thus high requirement is proposed to the disposal ability of equipment and I/O ability, make STP become network bottleneck, limit the bearing capacity of network, cause recall precision limited, reduce Consumer's Experience.In addition, due to for realizing the routing capabilities that addressing function adopts, such as, MSC (MobileSwitching Center, mobile switching centre) local number section analytic ability, disperses in each entity of Different Logic aspect in a network, once the topology of data storage network changes (adjustment or dilatation), all related entities all need to configure accordingly and adjust, and improve the difficulty of route adjustment.In addition, adopt multistage data routing mode also can reduce the redundancy ability of system, increase the failure risk of system.Once any first device breaks down in multistage STP equipment, data access flow process just cannot normally complete, and greatly affect the reliability of data network.
