20100284336 | METHOD FOR SELECTING A POLICY AND CHARGING RULES FUNCTION SERVER ON A NON-ROAMING SCENE - The present invention discloses a method for selecting a policy and charging rules function server in a non-roaming scenario to achieve that the PCC policies for each IP-CAN session are determined only by one PCRF. The method comprises of a Diameter Routing Agent (DRA) establishing an association relationship table in which IP Connectivity Access Network (IP-CAN) session information and corresponding address information of a Policy and Charging Rules Function (PCRF) server are stored; and when a Policy and Charging Enforcement Function (PCEF) entity and a Gateway Control Function Entity (GWCF) requests the PCRF for or to update a Policy and Charging Control (PCC) policy of one IP-CAN session, or when an Application Function (AF) entity sends application information or service information down to the PCRF, obtaining the address information of the PCRF associated with said IP-CAN session from said DRA, then performing subsequent processing. | 11-11-2010 |
20100291923 | METHOD FOR SELECTING POLICY AND CHARGING RULES FUNCTION - A method for selecting a policy and charging rules function. When a UE accesses a 3GPP system through a roaming architecture, upon receiving a session establishment request message sent by a PCC client located in the visited network, the DRA in the visited network forwards the message to a selected PCRF of the visited network according to the records stored locally or instructs the PCC client to transmit the session establishment request message to the selected PCRF of the visited network; and the PCRF of the visited network forwards the session establishment request message to a DRA of a home network, then the DRA of the home network forwards the message to the selected PCRF of the home network according to the records stored locally or instructs the PCRF of the visited network to transmit the session establishment request message to the selected PCRF of the home network. | 11-18-2010 |
20120020345 | METHOD FOR IMPLEMENTING LIMITED POLICY AND CHARGING CONTROL AND SYSTEM THEREOF - The present invention provides a method and system for implementing limited policy and charging control. The method comprises a PCRF determining whether a visited network where a UE roams supports PCC, and sending a message containing an identifier indicating the limited policy and charging control deployment to an AF. After receiving the message containing the identifier, the AF performs no subscription of the event trigger and/or cancels the subscription of the event trigger based on the identifier. Using the method and system in accordance with the present invention, the AF can be notified more conveniently and accurately of the current policy and charging control deployment situation when the limited policy and charging control is implemented (i.e., when the visited network does not support the PCC). Moreover, the AF may perform the corresponding operations according to the current policy and charging control deployment situation, thereby saving system resources. | 01-26-2012 |
20120158977 | Method and System for Transmitting a Bearer Control Mode in Roaming Scenarios - The present invention provides a method and system for transmitting a bearer control mode in a roaming scenario. The method includes: a hPCRF sets a bearer control mode of an IP-CAN session, and forwards the bearer control mode of the IP-CAN session to vPCRF through an S9 subsession corresponding to the IP-CAN session; or, an hPCRF sets a bearer control mode of a gateway control session, and forwards the bearer control mode of the gateway control session to the vPCRF through an S9 subsession corresponding to the gateway control session. The system includes an hPCRF and a vPCRF. The present invention enables the hPCRF to select different bearer control modes for a plurality of IP-CAN sessions established by a User Equipment (UE) and to forward to the vPCRF, and the vPCRF can further send the bearer control modes to the corresponding enforcement network elements to be executed. | 06-21-2012 |
20120170517 | METHOD AND SYSTEM FOR ACQUIRING SERVING GENERAL PACKET RADIO SERVICE SUPPORT NODE ADDRESS - The present invention discloses a method and system for acquiring an address of a Serving General Radio Packet Service support node (SGSN). The method comprises: a Policy and Charging Enforcement Function (PCEF) entity providing a SGSN change event trigger to a Policy and Charging Rules Function (PCRF) entity; and the PCRF entity reporting a SGSN change event and a new address of the SGSN to the PCEF entity after receiving the SGSN change event trigger. The method solves the problem that credit control management cannot be carried out for different general radio packet service support nodes during online charging. | 07-05-2012 |
20130223290 | POLICY AND CHARGING CONTROL METHOD SUPPORTING IP FLOW MOBILITY IN ROAMING SCENARIO - A policy and charging control method for supporting IP flow mobility in a roaming scenario includes: when a Visited Policy and Charging Rules Function (V-PCRF) receives IP flow mobility routing rule information reported by a Policy and Charging Enforcement Function (PCEF), and if a Home Policy and Charging Rules Function (H-PCRF) subscribes IP-CAN type change (IP-CAN_CHANGE) event trigger or access node gateway change (AN_GW_CHANGE) event trigger, the V-PCRF reporting the IP flow mobility routing rule information to the H-PCRF. With the present method, a visited network can execute the IP flow mobility locally, or compared with a method in which an interaction with the H-PCRF is required at any time, signaling overhead between the V-PCRF and the H-PCRF can be saved. | 08-29-2013 |
20140198728 | Information Transmission Method, Packet Data Gateway, and Policy and Charging Rules Function - Disclosed are an information transmission method, a packet data gateway, and a policy and charging rules function. The method includes: after receiving a Mobile IPv6 support for Dual Stack Hosts and Routers (DSMIPv6) binding update signaling, a packet data network gateway (P-GW) notifying a source User Datagram Protocol (UDP) port number of the DSMIPv6 binding update signaling to a Policy and Charging Rules Function (PCRF); and the PCRF notifying the source UDP port number of the DSMIPv6 binding update signaling to a fixed broadband access network. The above-mentioned method provides the UDP port number for the fixed broadband access network according to whether the IPSec capsulation is performed on the user plane data, which makes the fixed broadband access network be able to identify the user plane data of the user equipment correctly and perform a corresponding policy control. | 07-17-2014 |
20140310529 | HNB OR HeNB SECURITY ACCESS METHOD AND SYSTEM, AND CORE NETWORK ELEMENT - A Home (Evolved) NodeB (H(e)NB) security access method and system, and a core network element are disclosed. The method includes a security gateway (SeGW) signing a digital signature for identity information of an H(e)NB and sending the digital signature to the H(e)NB, the H(e)NB sending the identity information of the H(e)NB and the digital signature to the core network element, and the core network element performing a correctness verification on the identity information of the H(e)NB and the digital signature. | 10-16-2014 |
20140378131 | Policy Control Method And System For Converged Network - A policy control method for a converged network comprises: in a roaming scenario, after learning that a user equipment (UE) accesses a mobile network through a wireless local area network (WLAN) access, a visited policy and charging rules function (V-PCRF) establishing a subsession serving WLAN Offload when establishing an S9 session to a home policy and charging rules function (H-PCRF), and carrying a WLAN Offload instruction. With the present document, the WLAN offload data can be distinguished from data routed back to an EPC network in the roaming scenario, thereby delivering policy control for the WLAN offload data. | 12-25-2014 |
