20100121960 | METHOD AND SYSTEM FOR PROVIDING MOBILITY MANAGEMENT IN NETWORK - A method implemented by a gateway device which handles sessions over a network to which the gateway device is connected and which also enforces conditions of service provided to those network sessions, the method involving: receiving from a policy server a policy rules package, wherein the policy rules package specifies a set of rules that are to be applied to certain sessions handled by the gateway device and a set of criteria for identifying among a plurality of subscribers a group of all subscribers to which the rules are to be applied by the gateway device; based on set of criteria in the policy rules package identifying all subscribers with currently active sessions to whom the policy rules are to be applied; and applying the set of rules to the sessions of the identified subscribers. | 05-13-2010 |
20110165901 | METHODS, SYSTEMS, AND COMPUTER READABLE MEDIA FOR POLICY CHARGING AND RULES FUNCTION (PCRF) NODE SELECTION - The subject matter described herein includes methods, systems, and computer readable media for PCRF node selection. According to one aspect, a system for PCRF node selection is provided. The system includes a first PCRF selection node for receiving a first request message for which PCRF node selection is required. The first PCRF selection node determines whether to select the PCRF or to delegate selection of the PCRF. In response to a determination to delegate the selection of the PCRF, the first PCRF selection node generates and sends a second request message related to the first request message. The system further includes a second PCRF node for, in response to receiving the second request message from the first PCRF selection node, determining whether to select the PCRF or to delegate selection of the PCRF. In response to determining to select the PCRF, the second PCRF selection node selects the PCRF. | 07-07-2011 |
20110225280 | METHODS, SYSTEMS, AND COMPUTER READABLE MEDIA FOR COMMUNICATING POLICY INFORMATION BETWEEN A POLICY CHARGING AND RULES FUNCTION AND A SERVICE NODE - According to one aspect, the subject matter described herein includes a method for communicating policy information. The method includes steps occurring at a policy charging and rules function (PCRF) node. The method also includes receiving, from a service node, a message requesting a policy rule, wherein the message includes an Internet protocol (IP) address associated with a subscriber. The method further includes determining a network access identifier (NAI) for the subscriber based on the IP address. The method further includes selecting a policy rule for the subscriber based on the NAI. The method further includes communicating the policy rule to the service node. | 09-15-2011 |
20120282955 | METHODS, SYSTEMS, AND COMPUTER READABLE MEDIA FOR PROVIDING A USER RECORD DELETION NOTIFICATION - Methods, systems, and computer readable media for providing a user record deletion notification are disclosed. In one example, the method comprises determining, at a subscriber data management (SDM) node, that a service subscription to an access network is to be terminated, wherein the service subscription is associated with a subscriber user, generating, at the SDM node, a notification message that includes a deletion notification attribute, and sending the Diameter notification message to an application server associated with the access network. The method further includes terminating, at the application server, a communication service connection established between the subscriber user and the access network in response to detecting the deletion notification attribute in the notification message and deleting, in the SDM node, a user record associated with the service subscription after receiving notification of the connection termination. | 11-08-2012 |
20130021933 | RAN Analytics, Control And Tuning Via Multi-Protocol, Multi-Domain, And Multi-RAT Analysis - The present invention identifies methods and procedures for correlating control plane and user plane data, consolidating and abstracting the learned and correlated data in a form convenient for minimizing and exporting to other network devices, such as those in the Core Network and the Access Network, or the origin server, CDN devices or client device. These correlation methods may use Control Plane information from a plurality of interfaces in the RAN, and User plane information from other interfaces in the RAN or CN. IF the device is deployed as an inline proxy, this information may be exported using in-band communication, such as HTTP extension headers in HTTP Request or Response packets, or another protocol header, such as the IP or GTP-U header field. Alternatively, this information can be exported out-of-band using a separate protocol between the RAN Transit Network Device (RTND) and the receiving device. | 01-24-2013 |
20130258865 | Distributed RAN Information Collection, Consolidation And RAN-Analytics - Control Plane and User plane packet data are collected within the Radio Access Network using a plurality of network devices. Consolidation and summarization of this information is then performed to present a unified picture of RAN through abstract APIs to management and analytics applications. The invention identifies methods of retaining the collected network data, such as control and application protocol headers at the collection points, and consolidation and exporting this network data to management/reporting/analytics application using application driven rules for consolidation and summarization. Real-time statistical analysis tools, which may be used to predict failure and degradation trends and proactively control the underlying causes, are also disclosed. | 10-03-2013 |
20140233368 | METHODS, SYSTEMS, AND COMPUTER READABLE MEDIA FOR DETECTING ORPHAN SY OR RX SESSIONS USING AUDIT MESSAGES WITH FAKE PARAMETER VALUES - A policy and charging rules function (PCRF), generates a Diameter audit message concerning an application level Diameter session for which local resources are maintained by the PCRF. The PCRF includes, in the audit message, a fake parameter value. The PCRF sends the audit message with the fake parameter value to the OCS or the AF over an Sy or Rx interface. The PCRF receives a response to the audit message from the OCS or AF. The PCRF determines, based on the response, whether the application level session comprises and orphan session. The PCRF, in response to determining that the application level Diameter session comprises an orphan session frees the local resources maintained by the PCRF for the orphan session. | 08-21-2014 |
