In order to make the object, technical scheme and advantages of the embodiment of the invention clearer, below in conjunction with the embodiment of the present invention In attached drawing, technical scheme in the embodiment of the invention is clearly and completely described, it is clear that described embodiment is A part of the embodiment of the present invention, instead of all the embodiments.Based on the embodiments of the present invention, those of ordinary skill in the art Every other embodiment obtained without creative efforts, shall fall within the protection scope of the present invention.

There are three types of access technologies for current cordless communication network, and one is global system for mobile communications (Global System Of Mobile communication, referred to as GSM), commonly referred to as 2G；One is Universal Mobile Communication System (Universal Mobile Telecommunications System, referred to as UMTS), commonly referred to as 3G；And it drills for a long time Into (Long Term Evolved, referred to as LTE) system, commonly referred to as 4G.System architecture such as Fig. 1 under three kinds of access technologies It is shown.

The network architecture either under which kind of access technology can be divided into two parts, and one is to access mesh portions, and one Core network part.Core network part is divided into mobile management network element, gateway and the part PCC again.Access mesh portions are mainly born Radio access layer signaling and user data transmission are blamed, specifically, in gsm, access mesh portions are primarily referred to as in Fig. 1 GERAN (English are as follows: GSM EDGE Radio Access Network), including BTS and BSC；In umts, mesh portions are accessed The UTRAN being primarily referred to as in Fig. 1, including RNC and NodeB；In LTE system, access mesh portions are primarily referred to as the E- in Fig. 1 UTRAN, including eNodeB.Other parts in framework shown in Fig. 1 in addition to accessing mesh portions are core network part, wherein GSM It is referred to as mobile management network element with the MME in the SGSN and LTE system of UMTS, is mainly used for obtaining the signing number of user According to, responsible NAS signaling and the functions such as NAS signaling encryption and roaming, tracking, distributing user temporary identifications, security function Deng.The PGW in GGSN and LTE system in GSM and UMTS is gateway, is mainly responsible for strategy execution and charging and conjunction Method monitors correlation function.In addition, in core net there are one important component be the part PCC comprising PCRF entity and PCEF entity, usually and gateway, such as GGSN or PGW conjunction is set PCEF entity, and and user-subscribed database (Subscription Profile Repository, referred to as SPR), application function (Application Function, letter Referred to as AF) entity etc. realizes the effect of the part PCC together.SPR is not shown in Fig. 1.

PCRF entity is mainly according to carrier policy, the limitation to user access network, user contracting data and use The current factors such as business information of ongoing SDF in family, formulate corresponding strategy, which is known as PCC rule；PCEF entity The PCC rule that PCRF entity is formulated mainly is executed, such as according to PCC rule, SDF is detected and is measured, guarantees business Service quality (Quality of Service, referred to as QoS), user face flow detection and triggering control plane session management Etc..It further illustrates, for the QoS for guaranteeing business, all Internet protocols (Internet Protocol, the abbreviation that UE is issued It needs for IP) data packet or all IP data packets to be received by PCEF, number will be serviced according to the qos parameter of SDF by PCEF It is assisted according to stream and bearing binding, such as by QoS classification mark (QoS Class Identifier, referred to as QCI) and address resolution The identical server data stream of view (Address Resolution Protocol, referred to as ARP) is bundled in the same carrying, Flow control is executed in order to which other network elements in core net are based on carrying.In addition, the charging policy that PCEF can also be issued according to PCRF With charging mode etc., to the server data stream etc. received.

Currently, carrying out charging to the business datum of user is to execute the charging based on SDF granularity by PCEF entity.Current The charging based on application data stream is being discussed in 3GPP tissue.For current 3GPP tissue discussing based on using data The charging of stream, the embodiment of the invention provides following two solutions.One is in business detection function (Traffic Detection Function, referred to as TDF) physically execute the billing scheme based on application data stream, another kind be PCEF physically executes the billing scheme based on application data stream.

Wherein, TDF entity is one kind of deep-packet detection (Deep Packet Inspection, referred to as DPI) equipment Functional entity, what can be issued according to PCRF entity executes detection to data packet to the detection rule of data packet, such as detects certain The data packet of class application (QQ), or uniform resource locator (Uniform Resource Locator, abbreviation that detection is specified The data packet event is reported to PCRF entity after detecting the application data packet of the condition of satisfaction for the data packet etc. of URL).Separately Outside, TDF entity may also execute flow control, such as the Maximum Bit Rate limitation of uplink and downlink to the application data packet detected.Fig. 2 institute In being shown as wireless communication system control and managing, the data stream interface and direction in control plane and user face.Band arrow in as shown in Figure 2 Shown in the dotted line of head, the upstream data packet that UE is sent will first pass through PCEF entity, get to network side using TDF entity, Correspondingly, the downlink data packet that network side is sent will first pass through TDF entity as with the arrow shown in solid in Fig. 2, using PCEF entity gets to UE.
