Description
(1) technical field
The present invention relates to a kind of method of usage policy decision making function module controls telecommunication service quality, especially the method for usage policy decision making function module controls service quality in the 3G (Third Generation) Moblie network.
(2) background technology
At present, communication environment expands to the diversification that comprises voice, data and multimedia communication from simple telegram telephone communication and communicates by letter.The general solution of operator is professional corresponding business network, therefore a situation that has formed a plurality of business networks and deposited.And the purpose of the network integration helps realizing " unified experience " of user when enjoying multiple communication service just in order to carry out the communication of various information on a unified network.The fusion relatively paid close attention to of industry at present comprises the fusion etc. of fusion, mobile network and the fixed network of telecommunications network and the Internet.Wherein, 3G (Third Generation) Moblie standard collaboration items tissue (3rd GenerationPartnership Project; 3GPP) IP-based IP multimedia subsystem, IMS (the IP MultimediaSubsystem that proposes at Release5 (R5) version; IMS) technology is that IP-based mobile the fusion with fixed communication provides the foundation, and is thought an important stage of network evolution by industry.
The core characteristics of IMS are to adopt session initiation protocol (Session Initiation Protocol; SIP) and with the independence that inserts.At present, IMS supports GPRS (the General Packet Radio Service of 2.5G and 3G; GPRS) mobile access way, IMS is dissolved into next generation network (Next Generation Network simultaneously; NGN) in to support fixedly access way.Under the development trend of the network integration, 3GPP, european telecommunications standards institute (EuropeanTelecommunications Standards Institute; ETSI) and (the InternationalTelecommunication Union-Telecommunication of standardization department of international telecommunication union telecommunication; ITU-T) all in research based on the network integration scheme of IMS, purpose is to make IMS become general-purpose platform based on the SIP session, support simultaneously fixing, move and WLAN (wireless local area network) (WirelessLocal Area Network; WLAN) etc. plurality of access modes realizes the fusion of fixed network and mobile network.
The 3-G (Generation Three mobile communication system) core net comprises application layer, key-course, transport layer and Access Layer from top to bottom successively by vertical direction.Application layer is responsible for providing various value-added services and management function on the basis of call setup; Key-course is responsible for finishing the transmission of various calling controls and corresponding service process information; Transport layer is responsible for information translation that the user is sent here and is delivered to destination for the form that can transmit and with the information routing on the net, and this layer comprises various gateways and be responsible for the exchange/routing of network edge and core; Access Layer is responsible for the user is connected to network, concentrates its traffic carrying capacity and business is sent to the destination, comprises various access means and access node.
Along with the combination of mobile communication technology and IP technology, mobile network is from Circuit-switched global system for mobile communications (Global Systemfor Mobile Communications; GSM) network development is to the GPRS network of packet switching, and Zhongdao provides 3G Universal Mobile Telecommunications System (the Universal Mobile Telecommunication System of high-speed real-time business; UMTS) network.According to the difference of business to delay sensitive, UMTS system definition four kinds of bearer service classifications: conversation class, stream class, interactive class and background classes.How to guarantee mobile network service quality (Quality of Service; QoS) demand makes mobile network offer customer satisfaction system service according to the different business characteristics, is the problem that the communications field is more and more paid close attention to.IMS has taken into full account the demand of the actual operation of operator, has formulated related specifications aspect QoS.
Fig. 1 has described the UMTS packet domain in up-to-date Release 6 (R6) version of 3GPP and the QoS architectural framework of multimedia domain, MMD.This architectural framework is realized based on the policy control mechanism of business, is provided QoS dynamically to control.The functional entity that relates in the architectural framework among Fig. 1 has subscriber equipment (User Equipment; UE), Gateway GPRS Support Node (Gateway GPRS Supporting Node; GGSN), strategy decisive function (Policy Decision Function; PDF), application function (Application Function).Wherein, GGSN is positioned at transport layer, and PDF is positioned at key-course, and AF is positioned at application layer.
Strategy decisive function PDF is an independent functional entity, controls for all packet switch domain services provide based on the qos policy of business.PDF sets up utility cession from the application server request of being applied, and preengages required various media resources, formulates specific policing rule at user and application.The decision-making of PDF will be sent to the IP bearer management function of GGSN, and the parameter that GGSN should business maps directly to block data protocol context (Packet Data Protocol context; PDP context) or be mapped to IP layer parameter (RSVP Resource Reservation Protocol for example; RSVP).PDP Context is a database record information, is used to manage the data routing iinformation between reaching from UE to GGSN.The COPS agreement that Go interface between PDF and the GGSN adopts IETF to be responsible for, the Gq interface between PDF and the AF adopts Diameter, transmits relevant information and the strategy of QoS.
The QoS management of grouping bag is mainly finished by UE and GGSN, adopts differential service (the Difference Servie of ietf definition; DiffServ) and differentiated service code point (Differentiated Services Code Point; DSCP) function is classified to the grouping bag, gives different priority levels to inhomogeneous bag in transmission.GGSN can extract or extract configuration parameter from RSVP from PDP Context.Terminal UE also can provide DiffServ and DSCP function, but not necessarily.Application function AF applies for or revises medium when session is set up or in the session.
When 3GPP had stipulated to use terminal UE in IP-based environment, this UE need obtain two IP addresses, and one of them IP address is used for transmitting signaling, and this IP address is called main IP (Primary IP); Another IP address is used for transmitting media data (voice, video), and this IP address is called time IP (Secondary IP).There is a main PDP Context to write down main IP route corresponding to main IP, PDP Context record time IP route arranged one time corresponding to inferior IP.The PDF of 3GPP regulation provides QoS control in IMS basic procedure is as shown in Figure 2:
(1) subscriber equipment (UE) sends a service request information by session initiation protocol (SIP) signaling to the applied function module that voice or Video service are provided (AF), and this request message is an INVITE normally.
(2) AF is by Authentication Authorization request (the Authentication Authorization Request of Gq interface; AAR) message sends authorization requests to PDF, the needed QoS of the user who tells PDF to use above-mentioned service.
(3) PDF produces an authorization flag (Authorization Token; And the response of the Authentication Authorization by Gq interface (Authentication Authorization Answer AT); AAA) message is passed to AF with this AT.AT is a character string, marks the IP address of this PDF.
(4) AT of the above-mentioned PDF of the containing address that will receive of AF sends to UE by the SIP signaling.
(5) UE passes to GGSN with AT simultaneously with inferior PDP context activation in activating time PDP Context request message.
Its objective is the inferior IP address that obtains UE, so that UE tells that the transport layer at GGSN place is that transmission of media data is prepared.
(6) GGSN is by the request (Request of Go interface; REQ) message sends a request to PDF, has above-mentioned AT in this request.
(7) PDF compares with its generation and by Gq interface AT that sends and the AT that receives by Go interface, promptly carries out authentication process.If above-mentioned two AT are identical, then PDF sends an authentication decision information to GGSN, tells GGSN this subscription authentication success, can use the required QoS of this business; If above-mentioned two AT differences, then PDF sends an authentication decision information to GGSN, tells GGSN this subscription authentication failure, and subscriber equipment can't use this business.
But,, then require this UE to have very high disposal ability if require UE to support above-mentioned two IP addresses simultaneously according to the regulation of above-mentioned 3GPP.And present UE can only support main IP, can't support time IP, both can't support above-mentioned inferior PDP Context.So just can't provide the QoS of 3GPP defined to control in the network before Release6.
