20080225798 | PROACTIVE SEAMLESS SERVICE PROVISIONING IN MOBILE NETWORKS THROUGH TRANSFERRING OF APPLICATION CONTEXT - A method supporting relocation of an Internet Protocol session during a network layer handover is provided. Application context information is sent to a device. The application context information indicates activities to be executed pro-actively before a network layer handover and includes a requested communication requirement. A first message is received from the device that includes a first indicator indicating whether or not the device can satisfy the requested communication requirement. If the first indicator indicates that the device cannot satisfy the requested communication requirement, the application context information is sent to another device, and a second message is received from the other device. The second message includes a second indicator indicating whether or not the other device can satisfy the requested communication requirement. If the second indicator indicates that the other device can satisfy the requested communication requirement, the other device is selected as a target access router for the network layer handover. | 09-18-2008 |
20090254665 | Trigger-Based Session Completion Using External Parties - A method for performing Internet call processing related to the completion of session initiation requests is provided. The session initiation requests include one or more triggers. Based on the detection of one or more triggers, a call processing entity involved with processing the session initiation request transfers call processing to one or more third parties. Each third party performs additional call processing and returns a result to the call processing entity. Based on reception of the result, the call processing entity continues processing the session initiation request. The URI of one or more third parties may be specified in the session initiation request. Also, one or more third parties may be pre-specified. A special trust relationship may exist between a terminal related to the session initiation request and one or more third parties, and the third parties may therefore perform call processing using context specific information or confidential information. | 10-08-2009 |
20090271859 | SYSTEMS AND METHODS FOR RESTRICTING EVENT SUBSCRIPTIONS THROUGH PROXY-BASED FILTERING - A system, method and filter are provided for restricting event subscriptions. The system includes an event server, such as a session initiation protocol (SIP) event server, capable of maintaining at least one event. Also, the system includes a network entity, such as a requester, capable of sending a subscription message, such as a SIP SUBSCRIBE message, subscribing to the event. Further, the system includes a proxy, such as an SIP proxy, associated with the event server, and in coupled between the event server and the network entity. In this regard, the proxy is capable of receiving the subscription message. The system also includes a filter capable of receiving the subscription message from the proxy. Thereafter, the filter can determine whether the network entity is an authorized subscriber. Then, if the network entity is an authorized subscriber, the proxy can forward the subscription message to the event server. | 10-29-2009 |
20100205298 | Method, system and computer program to enable semantic mediation for SIP events through support of dynamically binding to and changing of application semantics of SIP events - An event notification system includes a data communications network ( | 08-12-2010 |
20110214164 | ACCESS RIGHT CONTROL USING ACCESS CONTROL ALERTS - Systems and methods are provided for providing access controlled event subscription and notification and event access change alerts. In some embodiments, the systems and methods of the present invention operate within a SIP infrastructure. As such, SIP SUBSCRIBE messages and SIP NOTIFY messages are used for subscribing to and receiving notifications related to access control. According to some embodiments, event access change alerts are used in conjunction with access controlled event subscription to provide an efficient method for providing access controlled event subscription using current access control information. | 09-01-2011 |
20140122630 | SYSTEM, METHOD AND COMPUTER PROGRAM PRODUCT FOR THE DELIVERY OF MEDIA CONTENT - A system, method and computer program product are provided for delivering media content. The system includes at least one recipient that may be associated with at least one recipient rule. The system also includes a sending entity capable of transmitting a multimedia message addressed to the recipients. The sending entity can also specify delivery rules in the message. In this regard, the multimedia message includes media content. The system further includes a network entity capable of receiving the multimedia message and identifying any recipient rules, sending entity rules and/or network rules associated with the multimedia message. The network entity can then deliver the media content to the recipients based upon respective rules. The network entity can also be capable of processing the media content based upon the rules before delivering the media content, such as by transcoding or truncating at least a portion of the media content prior to delivery. | 05-01-2014 |
