Communication control system, method and service controller structure based on the Signaling System Number 7 net
Technical field
The present invention relates to a kind of communication control system, method and service controller structure based on the Signaling System Number 7 net, the not communication of upgrading active service net and business device, just can implement intelligent network, mobile construction, realization provides the authentication triggering of customer service, detailed single charging, bit number ascending, number to carry crucial new business such as (Number Portability) to the control of communication service.
Background technology
In fixing and mobile radio communication, the key that realizes professional control is a signaling, and No.7 signalling system (SS7) is most widely used signaling method, and the Signaling System Number 7 net is the core support net of telecommunications network, the introducing of each call and most of new business all be unable to do without the support of Signaling System Number 7 net.
Signaling System Number 7 agreement and signaling message are the bases of realizing communication service control, and signaling message has write down the essential information of customer call behavior, can be used for detailed list and charge, call out value-added services such as monitoring.The Signaling System Number 7 agreement is divided into signaling network agreement and service application agreement, Telephone User Part of its application protocol (TUP) and ISDN(Integrated Service Digital Network) User Part (ISUP) are used for the circuit connection of controlling call, and intelligent network application part (INAP) and mobile network applying portion (MAP) are respectively applied for the Signalling exchange of IN service and mobile communication business.
Professional providing generally is to service application layer by the No.7 signalling system communicating control information, realize by the call treatment layer of service application layer and telecommunication node, it is the dialogue that belongs to service application layer, therefore, the modification of any function and control logic will relate to the modification of application layer, the cooperation of operation flow and the support of Signaling System Number 7 net.On communication network, realize new business, provide the equipment except that building necessary new business, also necessary online switching equipment and the signaling equipment of upgrading active service: as realizing the personalized user service authentication of fixed network, will upgrade active service net switching equipment to introduce ISUP, INAP or the MAP that can support the new business function, also will increase the disposal ability of communication equipment simultaneously new business; As realize crucial new business such as detailed single charging, bit number ascending, number carry, just must transform the function of active service Netcom letter equipment to support that these are new.This for the equipment of new introducing except that defining the communication standard in advance, it is not the thing that is difficult to, but in large scale and moved the active service communication equipment of several years and the change of network, then can make a motion and lead whole body, become the biggest obstacle of service implementation and network development.
Provide and the bearer network onrelevant of business are the targets that the communication network construction is pursued.What people often at first expected is intelligent network technology and HLR inquire response technology, on local network, carry out the intellectualized reconstruction of network, but this does not break away from the limitation of traditional exchange and intelligent network technology, its general character is in the application layer of bearer network the multi-modulation scheme switch to be upgraded to change or tandem exchange's replacing, requiring bearer network and signaling network to talk with in calling control and signaling when inducing one new business supports, network is needed modified recombinant, professional close-coupled with bearer network, user data still is scattered in the switch and is provided with, the extra telephone traffic that increases existing network, the business that needs to build the signaling network of stack and concentrate is carried out tables of data, some service implementation is limited by networking mode also, is difficult to solve investment and benefit in technology and networking, the contradiction of technology and development.Owing to the cooperation of signaling protocol, structure of data table and interface make the device intercommunicating of many producers also bring difficulty again, and this also abstains from concerning operator and future development.Public correspondence network planning mould is huge, standard is complicated, existing network is done upgrading change that investment is big, risk is high, influence service quality, also must consider the intensive data table the safe operation risk, tackle the strange land redundant configuration and the networks development evolution of surge telephone traffic.
ITU-T Q.700 (ITU-T Recommendation is TO CCITTSIGNALLING SYSTEM No.7 Q.700:INTRODUCTION) suggestion is summary to No.7 signalling system.The signaling network of No. 7 signalling is made up of exchange and processing node and the transmission link that is connected these nodes, the transmission link that is used to transmit signaling message is called signaling link, the exchange and the processing node that are connected by signaling link are called signalling point (SP), can realize that the signalling point that signal switching is handled is called Signaling Transfer Point, each SP or STP all have one or more signaling point codes and identify its identity, the signaling point code of each SP or STP is unduplicated in same signaling network, the data message of the control business that transmits on signaling link is called signaling message, signaling message is realized addressing and the routing of message in signaling network by the DPC in the message, and termination is called the signaling link terminal with the equipment of processing signaling message in SP or STP.
Fig. 1 shows typical No.7 signalling system message and transmits and professional control principle.No.7 signalling system is divided into Message Transfer Part (MTP) and service application layer, wherein: Message Transfer Part is divided into signaling data link (level 1) signaling link function (level 2) and signaling network functions (level 3) again, level 3 parts that are used for pass-along message are called signaling message and handle 3, and the control of communication service is that the protocol dialog by the service application layer of SP realizes the application controls logic.In the dialogue institute message transmitted of MTP level more than 2, be called message signal unit (MSU), by preceding described, the DPC in the routing label of MSU is used to realize the routing of message.Solve the contradiction of investment and benefit, technology and development, be independent of the new technology that the active service net provides business to face the future development again with regard to seeking.
The applicant provides " at Signaling System Number 7 chain circuit function layer identification processing method and device to signaling data " on October 15th, 2003, application number in for 200310107935.1 application for a patent for invention in the applying date, that is: between Signaling System Number 7 chain circuit function layer, introduce the signaling message content services device, for implementing specific transactions, this device coupling is serially connected in the Signaling System Number 7 link, only change the given content of Signaling System Number 7 message, just can realize value-added telecom services by this device.Realize one of content that professional control of communication network and the value-added concrete system and method for signaling are studied for the applicant always for how based on signaling method.
