Description
Technical field
The present invention relates to moving communicating field, relate in particular to a kind of user data and merge (User DataConvergence, UDC) route selection method of network system and UDC network system.
Background technology
(Internet Technology, IT) development of software and hardware technology and professional development are except traditional public switched telephone network (Public Switched Telephone Network, PSTN) network and the second generation (2 along with Internet technology
NdGeneration, 2G) outside the network, increasing communication network is introduced into and becomes standard, as the third generation (3
RdGeneration, 3G) network, IP Multimedia System (IP Multimedia Sub-System, IMS) network, micro-wave access global inter communication (WorldwideInteroperability for Microwave Access, WiMAX) network, flexible exchanging network etc., this causes rolling up of user data in the network.
Along with the surge of user data in the network, original storage of subscriber data and the mode that provides more and more have been difficult to adapt to developing rapidly of network.The data Decentralization causes operation property expenditure, and (junk data is difficult to eliminate for OperatingExpenditure, OPEX) high enterprise, and data consistency is difficult to guarantee that Information Security ensures difficulty, and data mining analysis lacks effective means.Add differing of storage network element external interface, cause the data access interface complexity, interface and professional close coupling, data can't transparently transmit, and new business is difficult to fast and effeciently carry out, and the user data management problem is obvious day by day.
For this reason, industry has proposed the notion of unified user data model, is about to the data fusion of same user distribution on different network elements, with user ID as basic identification, according to unified data structure organization, as unique user data source of all-network.
In physics realization, unified user data model is stored in the unique data storage network element of network: central database (Center Database, CDB), this centre data library storage user's unified data model, guarantee consistency, reliability and the fail safe of data, provide the open interface with professional and data independence, for other data query network elements provide data access service.
Terminal data, access or core network data, business datum and Internet business datum are merged, use and data decoupler, unified management is also set up unified subscriber data center, can simplify network, shorten the new business issuing time, the innovation of promoting business is laid a good foundation for operator provides competitive integrated services.
Fig. 1 has described third generation partner program in the prior art, and (3rd Generation PartnershipProject, 3GPP) tissue merges the network system model of being set up about user data.Wherein, the UDC network comprises application front end and the user data warehouse of supporting multiple application.Application front end is handled the applied logic with data independence, not responsible storing user data information; User data warehouse has merged various application datas as the subscriber data center in the network, and provides unified open Ud access interface for various application front end.
The UDC network system does not influence existing network system, and promptly application front end and core network element, operation layer are used and telecommunication service OSS (Business ﹠amp; Operation Supporting System, BOSS) existing interface between is unaffected.For example, support that (Home SubscriberService, HSS) application front end of Ying Yonging need be supported the S6a/S6d interface based on Diameter that HSS supports, Cx, Sh interface etc. in the home subscriber service.Support attaching position register (Home LocationRegister, HLR) application front end of Ying Yonging need support that HLR supports based on MAP (Mobile Application Part, the MAP) C of agreement, D, Gr interface etc.
Fig. 2 has described that operator is disposing a kind of application scenarios of user data coalescing network inside the province in the prior art.Operator disposes by province, and each is economized and disposes a unique user data warehouse, is positioned at provincial capital.Dispose a plurality of local area network inside the province, each local area network is disposed one or more application front ends, is used for load balancing.As shown in Figure 2, the mobile subscriber terminal MS1 (Mobile Station) that belongs to local second local area network (LAN) roams into local inside the province first local area network (LAN), and initiates login request message.Login request message, is kept at user registered address information in the user data warehouse by the HLR application front end by after effectively the HLR application front end is handled arbitrarily through mobile switch MSC1 (Mobile Switching Center) or Serving GPRS Support Node SGSN1 (Serving GPRS Supporting Node).
When user's subscription data changed, the forward-shifting service number that activated of user's modification for example, the user data warehouse message of need issuing a notice was notified the user subscription data information that registered network is upgraded.The route that user data warehouse can select arbitrarily effective HLR application front end to issue as notification message, selected HLR application front end may be positioned at this locality second local area network (LAN) that the user belongs to, and also may be positioned at this locality first local area network (LAN) at place, user roaming place.If HLR the 3rd application front end or HLR the 4th application front end that user data warehouse has selected this locality second local area network (LAN) of user attaching to dispose, to cause notification message from local second local area network (LAN) handle after No.7 nation-wide Network (Signaling SystemNo.7, SS7) public network is connected to local first local area network (LAN) in visit ground that the user registers.If HLR first application front end or HLR second application front end that notification message can directly be disposed by local first local area network (LAN) issue, will significantly reduce signaling so to a certain extent and make a circulation, improve the response speed of system.Especially when the user economizes internetwork roaming,, will make the circuitous phenomenon of signaling more serious if notification message issues from the user attaching network.
Fig. 3 has described a kind of application scenarios of operator's deployment user data coalescing network between economizing in the prior art.As shown in Figure 3, second user data warehouse that second province disposes has effective I P with HLR second application front end that first province disposes and is connected and data access interface, and HLR second application front end can directly be visited the user data of second user data warehouse.When if the user roams in first local area network (LAN) of this locality of first province, notification message is directly issued the signaling that effectively reduces the SS7 network circuitous by HLR second application front end by second user data warehouse, and improves the response speed of system.
For the application scenarios of cross operator network system, the circuitous problem of signaling exists equally.Fig. 4 has described a kind of application scenarios of cross operator network IP based network deployment user data coalescing network in the prior art.The application scenarios of cross operator network design and operator dispose the application scenarios of user data coalescing network between economizing similar substantially, and effective the connection and data access interface between the user data warehouse disposed between the operator and the application front end need be provided.
In sum, application scenarios based on the UDC of operator network system, still be faced with user data warehouse and how effectively select application front end, to reduce this technical problem of signalling route of the notification message that is handed down to the registered users registered network as far as possible, be necessary to provide the corresponding techniques scheme to solve.
