The method comprises the following steps of: receiving a resource request message of service flow from a policy and charging rules function (PCRF) by a resource control function (RCF); and allocating the resources by the RCF according to the resource request message.
Description
Technical field
The present invention relates to the communications field, relate in particular to a kind of method and system of in the full-service UNE, controlling resource.
Background technology
As shown in Figure 1, grouping system (the Evolved Packet System of the evolution that 3GPP proposes, EPS) by universal mobile telecommunications system land radio access web (the Evolved UniversalTerrestrial Radio Access Network of evolution, E-UTRAN), mobile management unit (MobilityManagement Entity, MME), gateway (Serving Gateway, S-GW), grouped data network gateway (Packet Data Network Gateway, P-GW or PDN GW), home subscriber server (Home Subscriber Server, HSS), authentication and authorization charging (the Authentication of 3GPP, Authorization and Accounting, AAA) server, "Policy and Charging Rules Function (Policy and Charging Rules Function, PCRF) form by entity and other support nodes.
In the system of EPS, Mobility Management Entity is responsible for the related work of chains of command such as the processing of mobile management, Non-Access Stratum signaling and the contextual management of user's mobile management; S-GW is the accessing gateway equipment that links to each other with E-UTRAN, transmits data between E-UTRAN and P-GW, and is responsible for pending datas such as paging are carried out buffer memory; P-GW is that (Packet DataNetwork, the PDN) borde gateway of network are responsible for the access of PDN and transmit data etc. between EPS and PDN for EPS and packet data network; S-GW and P-GW belong to the core net gateway; PCRF is the "Policy and Charging Rules Function entity, by interface Rx and carrier network agreement (Internet Protocol, IP) business network links to each other, obtain business information, in addition, also link to each other with gateway device in the network, be responsible for initiating the foundation that IP carries by the Gx/Gxa/Gxc interface, guarantee the QoS of business datum, and the control of chargeing accordingly.
The EPS system supports the intercommunication with non-3 GPP system, realizes that by the S2a/b/c interface wherein the P-GW in the EPS system is as the anchor point between 3GPP and non-3 GPP system.In the system of EPS, non-3 GPP system is divided into the non-3GPP IP access of trusted and trustless non-3GPP IP inserts.
Mode to non-3 GPP system access P-GW describes below:
The non-3GPP IP of trusted inserts and can directly be connected with P-GW by the S2a interface;
Trustless non-3GPP IP inserts the packet data gateway that needs through evolution, and (Evolved PacketData Gateway ePDG) links to each other with P-GW, and wherein the interface between ePDG and P-GW is S2b;
Subscriber equipment (User Equipment, UE) be connected with P-GW by interface S2c, wherein S2c can realize control and the mobility support that user's face is relevant, the mobility management protocol of its support for the mobile IP v 6 of supporting two stacks (Mobile IPv6 Support for Dual Stack Hosts and Routers, DSMIPv6).
In the EPS system, PCRF is by communicating as lower interface and other network elements:
When strategy and charge execution function (Policy and Charging Enforcement Function, PCEF) entity resides among the P-GW, passes through Gx interface exchange message between PCRF and the P-GW;
When the interface between P-GW and S-GW is based on PMIPv6, S-GW has bearing binding and event reporting function (Bearer Binding and Event Report Function, BBERF) entity carries out the function that QoS controls to business data flow, and PCRF is by Gxc interface and S-GW exchange message;
When the user inserts the EPS system by the non-3GPP connecting system of the resident trusted that BBERF arranged, between PCRF by Gxa interface and trusted non-3 GPP access network pass exchange message;
When UE roamed, visit ground PCRF and ownership place PCRF communicated by the S9 interface, and (Application Function AF) obtains the business information that is used to formulate the PCC strategy to PCRF from professional application function is provided by Rx interface simultaneously.
In 3GPP, (Access Point Name APN) can find corresponding PDN network by APN.Usually UE is called an IP connection Access Network (IP Connectivity Access Network, IP-CAN) session to a connection of PDN network.In the process of setting up the IP-CAN session, BBERF and PCEF respectively and set up the Diameter session between the PCRF transmit policy, billing information that session is controlled to IP-CAN and the business information that is used to generate strategy etc. by these Diameter sessions.
In the EPS system, be that the strategy of core and the control of chargeing wait network element and function to become the PCC system usually with execution with PCRF.In the PCC system, PCRF can dynamically issue the PCC strategy and give PCEF, comprises the information of QoS and charging in this PCC strategy.The business information that the user contracts among bearer related information that wherein said PCC strategy is the service related information that provides according to AF of PCRF, PCEF reports and the SPR is formulated.Wherein the PCC system is as shown in Figure 2:
PCRF is responsible for the formulation of strategy and charging regulation, by the Gx interface PCC strategy and the charging regulation of formulating is handed down to PCEF, and PCEF installs, carries out the PCC strategy, and reports dependent event, with the mutual charge information of charge system;
BBERF receives professional QoS rule by the Gxx interface from PCRF, the mutual charge information of discord charge system, the reporting of only responsible bearing binding and dependent event;
AF provides business information by Rx interface to PCRF;
SPR preserves the business information that the user contracts, and PCRF can be by the Sp interface to the signatory business information of SPR inquiring user;
PCEF sends to Online Charging System (OnlineCharging System by the Gy interface with online charging information, OSC) statistics of responsible online charging, by the Gz interface with offline charging information send to off-line accounting system (Offline Charging System, OFCS).
In the 3GPP mobile network, can set up the carrying of many different QoS priority between UE and the GW.Transmit in the carrying of corresponding Qos priority by Business Stream, guarantee professional QoS different QoS.The QoS that consults according to operation layer as AF is when PCRF initiates the policy control request, and PCRF can authorize according to user signing contract information (obtaining from SPR) and carrier policy, generates corresponding PCC strategy, is handed down to the PCEF function among the GW.Wherein said PCC strategy comprises following information: Business Stream five-tuple, QoS information (as QCI, upstream and downstream bandwidth etc.), charge information (as Charging Key etc.).Can set up corresponding carrying or revise the QoS attribute of existing carrying according to the QoS of business between UE and the GW, and carry out the bearing binding of uplink service flow in the UE side, promptly writing down this Business Stream should from which carrying transmission; Carry out the bearing binding of downlink business flow in the GW side, and beat corresponding QoS priority tag (as DSCP) for uplink traffic, to guarantee the QoS priority of uplink traffic in backbone network, simultaneously according to the charge information in the PCC strategy to the Business Stream control of chargeing.
In R8, can adopt two kinds of agreements of GTP or PMIP to communicate between S-GW and the P-GW.When adopting the GTP agreement, carrying is to be based upon between UE and the P-GW, therefore, only need carry out strategy and the control of chargeing by PCEF on P-GW; When adopting the PMIP agreement, carrying is to be based upon between UE and the S-GW, therefore need carry out bearing binding by the BBERF function on S-GW, and the assurance Business Stream to the QoS between the UE, carries out QoS and the control of chargeing by the PCEF function at S-GW simultaneously on P-GW.
