Description
Technical field
The present invention relates to telecommunications service network technology, particularly can handle public switched telephone network and described integrated services digital network business, the telecommunications service network technology based on the broadband packet transmission of fixing or mobile service can be provided for the end user based on broadband packet transmission.
Background technology
Integrated services digital network (Integrated Services Digital Network, be called for short " ISDN ") originated from 1967, be with integrated digital network (Integrated Digital Network, abbreviation " IDN ") communication network that forms for base growth, ISDN supports that numeral connects end to end, various communication services such as supporting telephone provide the user-network interface of standard to be convenient to various user terminals accesses.
Public switched telephone network (Public Switched Telephone Network is called for short " PSTN ") is a kind of common carrier network, and it provides based on the speech of exchange line and data communication services.
The professional general reference of PSTN and ISDN in traditional PSTN and isdn network, the general name of all kinds of business service that provide for the user.
PSTN and ISDN business realize in circuit commutative field traditionally, develop rapidly along with the packet-based communication technology, the soft switch that also can pass through next generation network (Next Generation Network is called for short " NGN ") at present realizes PSTN and ISDN business in packet domain.
The definition of " NGN " has the branch of broad sense, narrow sense.
Broad sense NGN makes a general reference all and adopts the soft-exchange construction of carrying, control separation and the telecommunications service network of broadband packet carrying, and no matter this network provides fixing or mobile service for the end user.The telecommunications service network of said here broadband packet carrying can be internetworking agreement (InternetProtocol is called for short " IP ") network, also can be asynchronous transfer mode (Asynchronous TransferMode is called for short " ATM ") network.The definition of the NGN that this respect can provide in February, 2004 with reference to ITU-T: NGN is a packet network, it provides the multiple business that comprises telecommunication service, can utilize various bandwidth and have service quality (Quality of Service, abbreviation " QoS ") tranmission techniques of ability, the realization business function separates with the bottom tranmission techniques; It allows the user to freely the inserting of different business provider network, and supports universal mobility, realizes consistency and the uniformity of user to the business use.
Narrow sense NGN then only refers to provide based on the broadband packet carrying, for fixed network inserts the network that the user provides C4/C5 business and IP multimedia service, and if no special instructions, the alleged NGN network of the present invention refers to " narrow sense NGN ".
In fixed network NGN, soft switch realizes PSTN and ISDN business as the call treatment node in the network.PSTN user and isdn user are by voice gateways (Audio Gateway, abbreviation " AG "), integrated access equipment (Integrated Access Device, be called for short " IAD ") etc. access device be linked in the soft switch, finish the memory management functions of its session control, professional control and user data by soft switch, for it provides PSTN and ISDN business.
There is following problem in this scheme that realizes by soft switch:
1. calling control and service control function are coupling in the same network node and finish, and very flexible is unfavorable for professional quick deployment and expansion.The modification of a function may cause the change of another function, has increased potential risks; The deployment of some business and expansion even can cause the upgrading of whole network node, the cost height.
2. soft switch supports fixed terminal to insert by various access devices, and as based on access devices such as the AG of different agreement or IAD, PSTN inserts relevant with the ISDN business realizing with the user.
3. soft switch also needs to provide Service Switching Point (ServiceSwitch Point is called for short " SSP ") function to realize the triggering of IN service except that realizing PSTN and ISDN business, owing to there is not unified trigger mechanism, there is conflict in two classes business.
4.PSTN and the ISDN business is dispersed in each call treatment node of NGN and finishes, each network node is difficult to the collaborative business of finishing.When business clashes, there is not clear and definite business arbitration point.
5.PSTN and the ISDN business is dispersed in each call treatment node of NGN and finishes, and requires each business all need repeat realization, promoting service cost height when promoting unified Service Brand in all soft switch of Home Network.
6.PSTN and the ISDN business is dispersed in each call treatment node of NGN and finishes, PSTN and ISDN business are difficult to as a network basic service ability, promptly can not provide the value-added service of combination as the shared assembly of a network and other professional cooperation the in the NGN network.
7. user data is dispersed in each call treatment node of NGN, and customer service obtains to be limited at its access point, even user terminal allows to move, also is difficult to obtain and original duplicate service, has also limited the unified of Service Brand and has promoted.
User data disperse to make NGN can't be between each call treatment node the share and access user data, the related service (wide area business) that causes striding the call treatment node provides difficulty.
In 3G (Third Generation) Moblie (The Third Generation is called for short " 3G "), a function and the similar system of above-mentioned fixed network NGN are arranged also, internet protocol multimedia core network subsystem that Here it is (IPMultimedia Subsystem is called for short " IMS ").
IMS is third generation partner program (3rd Generation Partnership Project, abbreviation " 3GPP ") IP Multimedia System in the WCDMA network of R5/R6 standard definition, be that the 3G mobile network is realized packet voice and grouped data, the unified multimedia service and the objective network of application are provided.IMS adopts the bearer path of IP packet domain as its control signaling and media delivery, adopt conversation initialized protocol (Session Initation Protocol, abbreviation " SIP ") agreement has realized that as call control signalling the three that service management, session control and carrying insert separates.Fig. 1 shows IMS network configuration in the 3GPP R5/R6 standard, about the detailed description of each network entity and relevant interface among the IMS, and can be referring to document " 3GPP TS 23.002 ".
Though IMS provides service management, session control and carrying to insert the mechanism that the three separates, but because the IMS standard is the design of 3G mobile system at first, do not support PSTN user and isdn user's access-in management control, therefore PSTN user and isdn user can't insert by the visit domain node of IMS standard definition, make PSTN user and isdn user to obtain PSTN and ISDN business service by other the network equipment.These other the network equipment or have all or part of shortcoming of fixed network NGN, even or solved these technical disadvantages, also be to adhere to different networks separately with the IMS territory, the network repeated construction.

Embodiment
For making the purpose, technical solutions and advantages of the present invention clearer, the present invention is described in further detail below in conjunction with accompanying drawing.
Basic principle of the present invention is in the IMS of 3GPP R5/R6 standard definition, introduces a new network node AGCF, by the control to access device, PSTN user and isdn user is linked in the IMS territory, thereby provides PSTN and ISDN business for it.Each network node functions of the IMS of 3GPP standard definition remains unchanged, because AGCF has shielded the difference that inserts the user, these insert the user can regard the IMS intra domain user as, the same with the 3G mobile subscriber.PSTN and ISDN business can also can be finished the control of basic service and supplementary service by AGCF by PSTN/ISDN Simulation (simulation) the AS centralized control among the IMS, are finished the control of the value-added service of expansion by PSTN/ISDN Simulation AS.
Describe the network configuration and the operation principle of packet switch domain service signal processing system in detail below in conjunction with Fig. 2.
In a preferred embodiment of the present invention, the packet switch domain service signal processing system comprises IMS10, PSTN/ISDN simulation AS20, AGCF30, AGF40, Access Network (Access Network, be called for short " AN ") 51, PSTN subscriber equipment (User Equipment, be called for short " UE ") 52, ISDNUE53 and subscriber exchange (Private Branch eXchange is called for short " PBX ") 54.
Wherein the annexation of each subsystem is: AS20 is by (the Home Subscriber Server of the home signature user server among Sh interface and the IMS10 in the PSTN/ISDN simulation, be called for short " HSS ") connect, by (the Subscription Locator Function of the Subscription Locator Function among Dh and the IMS10, be called for short " SLF ") connect, connect by the CSCF among ISC interface and the IMS10 (CallSession Control Function is called for short " CSCF ").AGCF30 is connected with CSCF among the IMS10 by the I1 interface, is connected with AGF40 by the I2 interface.AGF40 also is connected with AN51 by the V5 interface, be connected with PSTN UE 52 by the Z interface, by basic rate interface (Basic RateInterface, abbreviation " BRI ") interface is connected with ISDN UE 53, by Foreign Exchange Office (ForeignExchange Office, abbreviation " FXO ") interface/PRI (Primary Rate Interface is called for short " PRI ")/E1 interface is connected with PBX54.
Below introduce the function of each subsystem in detail:
IMS10 is 3GPP R5/R6 standard definition IMS, and wherein each network entity and relevant interface be identical with 3GPP IMS standard definition fully, and details can be referring to open source literature " 3GPP TS23.002 ".
Several network entities among the more relevant once IMS of following simple declaration with the present invention.
CSCF is used to finish conversation initialized protocol (Session Initation Protocol is called for short " the SIP ") conversation control function that inserts AGF and insert user (from the PSTN user and the isdn user of AGF40 access).Here the CSCF that says can comprise service call conversation control function (Serving CSCF is called for short " S-CSCF ") and enquiry call conversation control function (Interrogating-CSCF is called for short " I-CSCF ").
HSS is used to provide AGF to insert the memory management functions of user's user contracting data, and AGF access user's the PSTN and the memory management functions of ISDN service related data are provided.
SLF is used to provide AGF to insert user's Subscription Locator Function.
Though these several network entities all insert user's service for AGF, but the technical staff who is familiar with field of the present invention can know, in fact do not need these several network entities are done any modification, as long as it is just passable that AGF access user is used as common IMS intra domain user (as the 3G mobile subscriber) processing, this is because AGCF30 has shielded the difference that inserts the user.
PSTN/ISDN simulation AS20 is used to AGF to insert the user PSTN and the professional control of ISDN is provided.AS is the standard network entity among the IMS, so the difference of PSTN/ISDN simulation AS20 and general AS only provides PSTN and the professional control of ISDN being exclusively used in, and other type AS in IMS does not possess this function.But the interface of each network entity all is a standard among PSTN/ISDN simulation AS20 and the IMS10.
PSTN/ISDN simulation AS20 can have two kinds of concrete usages.
In a preferred embodiment of the present invention, PSTN/ISDN simulation AS20 provides all PSTN and the professional control of ISDN.The benefit of this mode is to call out control separates fully with professional control, and PSTN and ISDN business exist as the Network ability that a kind of IMS AS provides.In this mode, all subscription data of user and service related data are all in the HSS of IMS10.
In another preferred embodiment of the present invention, AGCF30 finishes the control to basic service and supplementary service, and PSTN/ISDN simulation AS20 finishes the control to the value-added service of expansion.A kind of scheme can realize the professional and ISDN business of PSTN faster before the benefit of this mode was relatively.This is not to design for realizing that PSTN and ISDN are professional because of Session Initiation Protocol at the beginning, PSTN/ISDN simulation AS20 finishes basic service and supplementary service, need AGCF30 finish certain customers' interface signaling and Session Initiation Protocol between mapping conversion or certain customers' interface signaling is encapsulated in the Session Initiation Protocol, wherein also may relate to the expansion of Session Initiation Protocol is used, as to the mapping of the hookflash event in the user interface signaling (pressing the R key) etc.In this mode, subscription data and the business datum relevant with supplementary service with the PSTN/ISDN basic service are placed on the AGCF, and other subscription data and service related data are placed among the HSS of IMS10.In this mode, unless user's exhalation is terminated because of professional control by AGCF30, otherwise user's all-calls still needs through IMS10, finishes routing addressing and the control that continues by S-CSCF.
A kind of transition scheme of scheme before can evolving to a kind of mode in back as existing network in the practical application.
AGCF30 is a key equipment of the present invention, it is the network entity that increases newly, be used to provide access control function to AGF 40, shielding AGF inserts the difference between user and the common IMS intra domain user, can satisfy the requirement that the session control of IMS core net and service control function and access user have nothing to do.AGCF can regard the another kind visit domain node of IMS as, acts on behalf of access function for AGF access user provides.
The concrete function of AGCF30 is as follows:
1. to access-in management and the controlled function of AGF40.
Signaling protocol on the I2 interface between AGCF30 and the AGF40 can but be not limited to be: H.248 agreement, MGCP (Media Gateway Control Protocol is called for short " MGCP "), Session Initiation Protocol, IUA/V5UA over SIGTRAN (the integrated services digital network network that transmits based on signaling Q.921 the user adaptive/links and accesses protocol version 5 user's adapting protocols) etc.
AGCF30 can manage and control one or more AGF40, among Fig. 2 in order to express convenient situation of only having drawn an AGF40.Each AGF40 has unique identification in AGCF30.The technical staff who is familiar with field of the present invention can know, AGCF30 can use for reference (the Media Gateway Controller of Media Gateway Controller in the prior art to management and the control of AGF40, abbreviation " MGC ") management and the controlled function to media gateway (Media Gateway is called for short " MG ") realizes.
