Description
Technical field
The present invention relates to communications field multi-protocols routing load and share, relate in particular to a kind of multi-protocol routing configuration device and method.
Background technology
Signalling system No.7 (Signaling System No.7, be called for short SS7) be (the International Telecommunication Union-TelecommunicationStandardization Sector of International Telecommunications Union, abbreviation ITU-T) agreement of one group of conventional telecommunications net of definition, be widely used in PSTN (Public Switched Telephone Network is called for short PSTN) and mobile network.Layer 3 agreement of Message Transfer Part (Message TransferPart 3 is called for short MTP3) are the network layer protocols of signalling system No.7 network, mainly finish Message Processing and signaling network management function.Message SCCP (SignallingConnection Control Part is called for short SCCP) for the MTP3 layer provides additional function, is realized the information that transfer circuit/inverter circuit is relevant, sets up and does not have connection/connection-oriented network service.
Signaling transmission (Signaling Transport, abbreviation SIGTRAN) agreement is the Internet engineering duty group (The Internet Engineering Task Force, abbreviation IETF) one group of definition is used for transmitting legacy circuit-switched networks network (Switch CircuitNetwork at emerging IP Telecommunication Network network, be called for short SCN) agreement of signaling, also can be used for the intercommunication between the point-to-point of inside, IP territory.The adapting protocol of SCCP layer---signaling connection control part customer message adaptation layer (Signalling Connection Control Part User Adaptation Layer, be called for short SUA), map addresses and routing function are provided, and Network Management Function, the message that SUA can finish the User Part of SCCP among the SS7 in the IP territory transmits, and the network layer management function of MTP3 layer.
In the evolution and fusion process of communication network, need guarantee most possibly that original networking mode and resource continue to obtain to utilize and be not wasted, so just might appear at the situation that has SS7 and SIGTRAN transmission means between two signalling points simultaneously, promptly SCCP/MTP3 and SUA agreement are safeguarded the route between two signalling points simultaneously.The typical networking of this situation as depicted in figs. 1 and 2.
Among Fig. 1, A, B two signalling points adopt SCCP/MTP3 and the intercommunication of SUA dual mode simultaneously; In Fig. 2, A, B are SGW, and C is the signalling point in the IP territory, and the transmission means of direct SUA is arranged between A, B two SGWs and the C signalling point, adopt the SS7 transmission means between A, B two SGWs.From the A signalling point, have two kinds of routing modes to the C signalling point: a kind of is directly to transmit by the SUA mode; Another kind is to be transferred to B by A to the SCCP/MTP3 mode of B signalling point, is transmitted to the C signalling point by the B signalling point again.
Under the situation that has SS7 and SIGTRAN signaling transmission means between two signalling points simultaneously, SCCP/MTP3 and SUA provide the network layer service to the user, so there is the matching problem of dual mode route.The message routing of SCCP/MTP3 is to find destination signaling point link corresponding group by the route that sets in advance, and then determine a link of link group by the load sharing algorithm, the MTP3 routing iinformation comprises destination code (Destination PointCode, abbreviation DPC), origin point coding (Originating Point Code, abbreviation OPC), business information eight bit byte (Service Information Octet, abbreviation SIO), cic circuit identification code information such as (Circuit Identification Code are called for short CIC); And the message routing of SUA is mated by routing key and is realized, application server (ApplicationServer is called for short AS) is determined professional by the various combination of routing iinformation, and the various combination of routing iinformation just correspondence a routing key; When message matches an AS by routing key after, again by the application server instance (Application Server Provider be called for short ASP) of load sharing algorithmic match below AS.
The message of SCCP and SUA is to carry out intercommunication on SGW (Signaling Gateway is called for short SG).
The last SCCP of SG can judge whether this message is sent to the point in IP territory after receiving incoming message from No. seven territories, according to whether having AS, judges whether to give the route controlled function of SUA; Equally, the last SUA of SG can judge that whether this message is sent to the point in No. seven territories, then directly gives the route controlled function of SCCP in this way after receiving incoming message from the IP territory.
Yet because SCCP/MTP3 adheres to different protocol suites separately with SUA, their routing management is relatively independent, how to allow both realize route simultaneously between two offices, and this routing mode and route cooperate, at present also without any protocol specification and solution.Along with telecommunications gradually toward the transition of IP territory, and operator is reluctant to give up under the situation in No. seven territories of tradition, solves this type of problem and has very big realistic meaning and using value, can be for saving cost, widening the different agreement networking of route simultaneously and use reference frame is provided.

Step C: judge the route fit system of configuration, shown in the step 401 among Fig. 5, if active/standby mode, then execution in step D; If load sharing mode, then execution in step F.
Step D:CRM module 305 disposes normal route and route stand-by respectively.CRM module 305 is judged the state of current route, and as the step 402 among Fig. 5, if current route is unavailable, then to put the route that reports be current route to CRM module 305, and reports the route can be with to database and message processing module; If current route can be used, execution in step E.
Step e: the available route that judgement reports and which height of priority of current route, if available route is higher than current route, then putting available route is current route, and former low priority route withdraws from service; Otherwise, then do not upgrade route, finish the handling process of CRM module 305.
Step F: judge whether current route is available, as the step 403 among Fig. 5, if available, the available route that then will report adds in the current route, and according to the distribution principle of load sharing, drops into service with former route, the load sharing business; If current route is unavailable, then putting the available route that reports is current route, and reports route to use to database and message processing module.
Step G:CRM module 305 is judged the route fit system of configuration, as the step 501 among Fig. 6, if active/standby mode, then execution in step H; If load sharing mode, then execution in step L.
The unavailable route that 305 judgements of step H:CRM module report and which height of priority of current route, shown in the step 502 among Fig. 6, if unavailable road is the low priority route, execution in step I then, if cannot route be the high priority route, execution in step K then.
Step I:CRM module 305 judges whether the unavailable route that reports is current route, shown in the step 504 among Fig. 6, if current route, then execution in step J; If not current route, then do not upgrade, and finish CRM module 305 handling processes.
Step J: it is unavailable putting routing state, reports unavailable database and the message processing module given of route.
Step K: CRM module 305 judges whether the low priority route is available, and shown in the step 505 among Fig. 6, if the low priority route can be used, then putting the low priority route is current route; If the low priority routing state is unavailable, then execution in step J.
Step L:CRM module 305 judges whether another route is available, and as the step 503 among Fig. 6, if available, then business is handled on another available route; If unavailable, execution in step J then.
