Description
Technical field
The present invention relates to communication technical field, be particularly applied to fixedly under Mobile Convergence scene a kind of sign mapping method and equipment and policy control method and system.
Background technology
For meet operator at Service control the demand aspect becoming more meticulous, (The 3 for third generation partner program
rdgeneration Partnership Project, 3GPP) in introduced strategy and charging control (Policy and Charging Control, PCC) framework.The PCC framework of 3GPP standard definition mainly comprises: policy charging rule function (Policy and Charging Rules Function, PCRF), policy and charging enforcement function (Policy and Charging Enforcement Function, PCEF), user data register (Subscriber Profile Register, SPR) and the functional entity such as Online Charging System (Online Charging System, OCS).
PCRF carries out the functional entity of policy control in operator's core net, can provide the PCC of subscriber equipment (User Equipment, UE) mutual for gateway (Gateway, GW).During mobile UE core network access, the PCC signaling process between gateway and PCRF is shown in Figure 1, and wherein, PCEF realizes on GW.Referring to Fig. 1, IP connects Access Network (IP Connectivity Access Network, IP-CAN) session establishment process and comprises the following steps:
Step 101, complete gateway control session and set up (Gateway Control Session Establishment), this process relates to bearing binding and event reporting function (the Bearing Binding and Event Report Function in GW, BBERF) and the "Policy and Charging Rules Function (Visit-PCRF of PCEF, visited network, V-PCRF) and the "Policy and Charging Rules Function (Home-PCRF, H-PCRF) of home network;
The PCEF of step 102, GW receives the request (Establish IP-CAN Bearer Request) of setting up IP-CAN carrying from mobile UE;
Step 103, PCEF initiate IP-CAN session establishment Indication message (Indication of IP-CAN Session Establishment) to H-PCRF; Wherein, this Indication message comprises that this moves the information such as the mobile logo of UE, APN (Access Point Name, APN); Wherein, mobile logo refers to that 3GPP core net is the sign that mobile UE distributes, this mobile logo is used for 3GPP core net unique identification mobile subscriber, as IMSI International Mobile Subscriber Identity (International Mobile Subscriber Identifier, IMSI), network access Identifier (Network Access Identifier, NAI) etc.;
If there is no the CAMEL-Subscription-Information of UE in step 104 H-PCRF, PCRF sends request to SPR the CAMEL-Subscription-Information that (Profile Request) moves UE to obtain this, and wherein, the request of transmission comprises that this moves the mobile logo of UE;
Step 105, SPR return to request response (Profile Response) to H-PCRF, and carry the CAMEL-Subscription-Information that this moves UE, and wherein, CAMEL-Subscription-Information comprises the business that this moves UE permission etc.;
Step 106, H-PCRF carry out strategic decision-making (Policy Decision);
Step 107, H-PCRF are to PCEE feedback (Acknowledge of IP-CAN Session Establishment) result of decision, and wherein, the result of decision comprises PCC rule, as service quality (Quality of Service, QoS) rule;
If step 108 has online charging, PCEF sends request (Credit Request) to Online Charging System (Online Charging System, OCS), to obtain credit information;
Step 109, OCS return to request response (Credit Response) to PCEF, and carry required credit information;
Step 110, PCEF return to IP-CAN carrying to mobile UE and set up response (Establish IP-CAN Bearer Response);
If step 111 has been applied network control, GW initiates to set up extra IP-CAN carrying (IP-CAN Bearer Signaling);
Step 112, PCEF send IP-CAN session establishment feedback (IP-CAN Session Establishment Acknowledge) to H-PCRF.
Along with the development of the communication technology, fixed network and mobile network's fusion is the inexorable trend of network Development.Fixing Mobile Convergence (Fixed Mobile Convergence, FMC) in technology, allow the policy control entity (being PCRF) in mobile network to carry out policy control to permanent plant (Fixed Device), wherein, permanent plant refers to by wired mode (as ADSL (Asymmetric Digital Subscriber Line) (Asymmetric Digital Subscriber Line, ADSL), optical fiber etc.) subscriber equipment of access network, for example, the equipment such as IPTV (Interactive Personality Television, IPTV), Set Top Box.
