Description

Carry out the method and the device of IN service exploitation in the next generation network

Technical field

The present invention relates to mechanics of communication, be specifically related to carry out in a kind of next generation network the method and the device of IN service exploitation.

Background technology

Along with society, economic and scientific and technical continuous development, people increase day by day to the demand of information, and various users also become to the demand of telecommunication service and become increasingly complex, and this can provide all telecommunication services to the user rapidly and neatly with regard to requiring telecommunications network.Traditional way is: user personality control concentrates in each switch, a kind of new business of every increase, and all switch just need a part of software of increase in the net.Because switch quantity is very huge, and its type is varied, the structure of every kind of switch, software, method for designing etc. have nothing in common with each other.It is contemplated that, a kind of new business of every increase, whole switch softwares are made amendment in necessarily requiring to net, and not only workload is very big, and causes owing to business norms are understood differently, and the intercommunication of various inter-exchange new business variety of issue occurs through regular meeting.Therefore, traditional new business provides the method cost very high, poor reliability, and need the long period.

Intelligent network technology is to overcome these shortcomings to arise at the historic moment just.Its basic thought is: switch is only finished the most basic function that continues, and all value-added services provide by another complementary network-intelligent network.By intelligent network, operator can its network of optimal, and new telecommunication service is provided as early as possible; Can design business according to user's needs separately, to other service supplier open network, additional income, protection user's investment.

As shown in Figure 1, intelligent network generally is made up of several parts such as Service Switching Point 11, Service Control Point 12, service data point (SDP) 13, ip intelligent peripherals (IP) 14, business management system (SMS) 15, service creation environments (SCE) 16, and wherein the SCP of apart from each other can be connected by Signaling Transfer Point 17 with SSP.

The conceptual model INCM of intelligent network (Intelligent Network Concept Model) is made up of four planes, comprising: service plane, General Function Platform, distributed functional plane and physical plane.All briefly has expressed by the formed network of intelligent network in ability that different aspect provided on each plane.Wherein,

Service plane has reflected the business that intelligent network provides in the face of the user.As shown in Figure 3, each business is formed by service feature.A kind of business can only have a kind of service feature, also can have several service features.At least need two service features as freephone service: a number of the first (OneNumber); It two is reverse charging (Reverse Charging), and by called centralized charging, the calling subscriber need not to pay.Minimum service unit is exactly a single service feature.The different capable phase of every kind of agreement all have new enhancing to service feature.

General Function Platform has reflected total function that intelligent network had, and these functions should be able to guarantee that service feature is implemented in the service plane.The funtion part that it comprises has the starting point POI (Point of Initiation) and reentry point POR (Point of Return) between basic call processing section BCP (Basic CallProcessing), service independent block SIB (Service Independent Building Block), BCP and the SIB.A service feature in service plane needs that several SIB implement in the General Function Platform.In General Function Platform, very part and parcel is a service logic, and it has illustrated provides one when professional, the model of SIB link and order (promptly realize certain professional needed SIB and be connected), and the data parameters of each SIB.

Distributed functional plane has been introduced each functional entity FE (FunctionEntity) of being included in this plane and the function of each SIB of being made of Function Entity Action FEA FEA (Function Entity Actions), and Distributed Service Logic has been described.Distributed Service Logic mainly comprises the action of each functional entity when realizing the SIB function and the information flow between functional entity.

What physical plane solved is which type of physical entity to be implemented in desired function in the distributed functional plane with.A function is implemented in a plurality of physical entities possibly, also may several functions implement in a physical entity.

At present, International Telecommunications Union on General Function Platform, defined some standards can reusable functional block, be called the formation piece with independent of service, i.e. service independent block (SIB).Each service independent block is finished the network function of certain standard, as Translate (translation)-SIB, User Interaction (user interactions)-SIB, SDM (business datum user)-SIB or the like.Utilize these standards reusable, the different service attribute of can arranging in pairs or groups out as playing with building blocks, and then constitute different business.These functional modules are to be embodied by its functional entity in specific implementation.A functional module can be made up of a functional entity or several functional entity.Different SIB compound modes is equipped with suitable parameter again and has just constituted different business, SIB is combined formed SIB linking relationship just be called this professional Global Service Logic (GSL, GlobalService Logic).In addition, because IN service is a kind of supplementary service that has increased some service features on the basic service basis, therefore also need to have and handle the function that basic service is called out BCP (Basic CallProcess), BCP is a special SIB, and it is used for representing to start the ordinary call process of IN service.In sum, mainly comprise following three parts in IN service: basic call treatments B CP, service independent block SIB and Global Service Logic GSL, the graph-based of GSL as shown in Figure 2.

Like this, when new business demand, professional designer only need describe out a service needed and use which SIB, the sequencing between these SIB, and the input of each SIB, output parameter etc. have promptly been finished the design of a business.This makes professional design not only standard but also fast and flexible provides a good environment for designing and develop new business rapidly.But existing SIB only supports traditional arrowband intelligent network, such as, INAP (Intelligent Network Application Protocol, intelligent network application protocol)/CAP (CAMELApplication Protocol, the CAMEL application protocol)/MAP (Mobile Application Part, MAP) etc., do not support to use SIP (Session initial protocol, session initiation protocol) next generation network of agreement (NGN, Next Generation Network).
