Description

Method, system and functional entity for packet stream optimization that application affairs detects
Technical field
The present invention relates to the communications field, especially relate to method, system and functional entity for packet stream optimization that a kind of application affairs detects.
Background technology
Defined strategy in the standardized partnership projects of 3G (Third Generation) Moblie (3GPP) and control (PCC, the Policy and Charging Control) framework that charges, satisfied with this different business is carried out different service quality (QoS) control and charging demand.The PCC framework is a functional framework that can be applied to multiple access technology, some typical access technologies comprise universal mobile telecommunications system (UMTS) terrestrial radio Access Network (UTRAN), GSM EDGE Radio Access Network (GERAN) and I-WLAN (InterworkingWLAN, interworking WLAN (specially referring to and 3GPP system alleyway)) etc.Among the TS 23.203 the PCC framework is defined, as shown in Figure 1.
The PCC framework has mainly been realized two big functions, the one, and policy control functions, another is a billing function.Policy control functions mainly comprises: service parameter (mainly the being qos parameter) negotiations process to the user is monitored; According to the business information that is obtained, the employed network carrying resource of business is authorized; Control whether passing through of Business Stream in real time at Data-carrying face; The associated change advisory of service surface is arrived Data-carrying face; With the associated change advisory of Data-carrying face to service surface etc.; Carry out policy control based on user signing contract information.In the PCC framework, the entity that policy control functions relates generally to comprises AF entity (Application Function, Application Function), PCRF entity (Policy and Charging RulesFunctions, strategy and charging rule functions), PCEF entity (Policy and Charging EnforcementFunction, strategy and charging execution function entity) and SPR (Subscription Profile Repository, signatory specification storehouse) etc.
Billing function mainly comprises: integrated service information, beared information and user signing contract information, formulate charging regulation; Between the metering data of the metering data of service surface and loading end, carry out association; Under dynamic charge mode, carry out credit control.Under the PCC framework, the entity that billing function relates generally to comprises AF, PCRF, PCEF, SPR, OCS (Online Charging System, Online Charging System) and OFCS (OfflineCharging System, off-line accounting system) etc.
Functional description to some entities in the PCC framework shown in Figure 1 is as follows:
AF: Application Function.Being mainly PCRF formulation strategy and chargeing to control dynamically provides application layer conversation information, and for example: the P-CSCF among the IMS (IP Multimedia Subsystem, IP Multimedia System) just belongs to AF.
PCRF: policy control and charging controlled function entity.According to the current ongoing applied business information of restriction, the user of user access network, the configuration of local operator and user signing contract information, work out corresponding strategy, and strategy is offered the PCEF execution.Strategy comprises: business data flow detection, QoS control, gate and based on the charging of stream etc.
PCEF: the strategy and the execution entity that charges.Carry out that PCRF issues or the strategy of appointment, promptly finish detection to business data flow, guarantee business data flow QoS, gate, finish the functions such as session of on-line charging and triggering and chain of command.For example: GGSN (GGSN) entity in (GPRS) is also got in the wireless universal grouping.
Some interface functions in the PCC framework shown in Figure 1 are described below:
Rx: this reference point is used for AF and issues the application layer conversation relevant information, comprises the required bandwidth information of IP filter, Business Stream that is used for the identification services data flow, and this interface uses the Diameter of ietf definition.
Gx: this reference point is used for PCRF and dynamically controls the PCC rule that PCEF carries out.Possesses following function: set up, safeguard and stop IP-CAN session (IP-CAN SESSION); PCEF is to PCRF request PCC rule; PCRF provides PCC rule to PCEF; Consult the IP-CAN carrying and set up pattern etc.This reference point is used the Diameter ((authentication, mandate, charging) technology of a new generation, the interface of inter-entity uses in the IP multimedia domain, MMD of 3G network) of ietf definition.
In the transfer of data of network, a business data flow is made of a plurality of IP messages that comprise five-tuple (source address, source port number, destination address, destination slogan, agreement).The business that the user carries out can be made up of a plurality of business data flows, and for example the user carries out in the multimedia conversation, and a video flowing is exactly a business data flow.
In the PCC policy control architecture of definition, PCRF needs to carry out for the professional PCEF that formulates corresponding strategy and be handed down on the bearing bed entity according to the tactful contextual information that obtains from each functional entity (AF/PCEF/SPR etc.), to realize QoS, the gate to business, the policy control of charging.
Yet along with networks development and professional abundant, realized more other functions on the PCC framework, (Packet Flow Optimization PFO) is exactly wherein a kind of in stream of packets optimization.
The PFO function is under the control of strategy IP stream to be filtered, and policing rule is specified PFO which kind of should detect and used, and how to handle after detecting this application.Two kinds of frameworks are arranged on specific implementation, and a kind of is the framework that separates, i.e. PFO function conduct is the bearing bed functional entity independently, and (GW) separates with gateway; Another kind is the framework of unification, and promptly PCEF and PFO function are present on gateway (GW) entity jointly.No matter under which kind of PFO framework, PCRF can activate the detection of application affairs according to the ability of PFO.PCRF need provide following activation application affairs and detect indication information when activating the application affairs detection: the identification information that detects application that activates, as application such as BT application, FTP application, RTSP streaming media video program request application, online games; Optionally also may provide the detection rule of application affairs, comprise the application affairs that detects that activates, as application start, use terminations, apply changes etc., and some restrictive conditions that also may provide the coupling applying detection that activates are as the filtering rule of application etc.And can be pre-configured on the PFO function application affairs detect rule, PCRF indicates and needs to activate which bar rule activating the identification information that can only carry application when application affairs detects so; Certainly the detection rule of application affairs also can be issued to the PFO execution by PCRF by the indication information that activates the application affairs detection fully.But problem is that existing application affairs detects activation mechanism only at the user, promptly if desired a plurality of users is carried out the detection of identical application affairs, and then PCRF need carry out the activation that application affairs detects respectively at each user.
In actual applications, there is the demand of a plurality of users being taked the same application event detection rules.For example: telecom operators forbid that all users carry out the SKYPE and the BT that use the P2P technology and download, and are carrying out this when professional when the PFO Function detection to any user, need take identical tactful refusing user's to carry out this business; And for example: the mode that a lot of users take monthly payment to pay is experienced IPTV VOD service (VOD), when PFO detects this type of user and carries out video-on-demand service, can take identical charging policy or QoS control strategy to this business, this strategy can obtain by local configuration or to the PCRF request.
For above-mentioned these scenes, the existing application affairs testing mechanism that activates also can't satisfy these users sharing application event detection rules demand when commencing business.Current mechanism has only realized setting up independently respectively to each user, and application affairs detects rule, if when satisfying above-mentioned application demand with current mechanism, will cause subscribing to/activate problems such as inefficiency that application affairs detects, maintenance and management complexity, can't satisfy same application affairs and detect rule use in multi-user's demand.
