20100135245 | Method for Avoiding Resource Being Released Mistakenly during Tracking Area Update or Handover Process - A method for avoiding resource being released mistakenly during tracking area update or handover process comprising: determining, by a target Mobility Management Entity MME, whether to use an old System Architecture Evolution Serving GW or to reselect a new Serving GW; if the target MME determines to select a new serving GW, notifying the original MME, the original MME sending a request for deleting bearer to the old Serving GW. The technical scheme of the present invention can avoid that the original MME will still send a request for deleting subscriber context to the old Serving GW when the target MME still uses the old Serving GW rather than selects a new one during tracking area update or handover process of the subscriber, which results in the appearance of a problem that the resource related to the subscriber in the old Serving GW is released mistakenly. | 06-03-2010 |
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 |
20120163300 | METHOD AND SYSTEM FOR ACQUIRING ROUTE STRATEGIES - The present invention discloses a method and system for acquiring routing strategy. In the solution of the present invention, a routing strategy provision unit sends routing strategies of local IP access to radio side network elements; the radio side network elements receive the routing strategies of local IP access. With the solution of the present invention, the radio side network elements are able to acquire the routing strategies of local IP access at the network element level or the user level, so that the radio side network elements transmit data according to the routing strategies, and the radio side network elements can effectively offload the data with the acquired routing strategies. Besides, in the solution of the present invention, the routing strategies might be for users, that is, different routing strategies might be made for different users, thereby improving the user experience and promoting generalization and popularization of services. | 06-28-2012 |
20130203414 | Mobile Terminal Registration Method in a Radio Network - A mobile terminal registration method in a radio network includes: a. A mobile terminal sending a non-access stratum message and identifier information of last registration to a radio access network unit, and the identifier information comprising the Serving CN Node identifier, Serving CN Node pool identifier and Public Land Mobile Network Identifier; b. If the radio access network unit determines that the identifier information is invalid, the radio access network unit allocating a Serving CN Node to the mobile terminal and sending the non-access stratum message to the Serving CN Node; c. After the Serving CN Node receives the non-access stratum message, if determining that a registration request of mobile terminal can be accepted, the Serving CN Node sending a success response message to the mobile terminal, and the message carrying identifier information of current Serving CN Node; d. The mobile terminal saving the new identifier information. | 08-08-2013 |
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 |
