| 20090129307 | Data Over Signaling (Dos) Optimization Over Wireless Access Networks - The present invention supports a communication protocol on a wireless communication network to transmit application data on the control channel to an access terminal. Base transceiver stations are grouped and configured into paging zones. The radio network controller transmits a page message and application data to the base transceiver stations in the paging zone where the access terminal is located. Each of the base transceiver stations transmits a page and buffers the application data. The buffered application data is only transmitted by the base transceiver station receiving a response to the page. | 05-21-2009 |
| 20090129388 | Sip header reduction - A SIP header reduction protocol operating on a communication network to compress the SIP header fields on SIP control messages used to initiate a SIP communication session. The new protocol is implemented on the mobile use equipment (UE) ( | 05-21-2009 |
| 20090135783 | FMIPv6 Intergration with Wimax - A fast handover protocol standard implemented on WiMAX networks integrating Internet protocol fast handover messaging. A standard for performing handover in four scenarios is offered with an embodiment for the message flow to perform the handover. The four scenarios include a mobile subscriber station initiated predictive hand-off, a network initiated predictive hand-off, a mobile subscriber station initiated reactive hand-off, and a network initiated reactive hand-off. In general, Internet Protocol control messages for fast hand-off or handover are used on the WiMAX network. Fast binding and fast binding acknowledge messages are exchanged between two WiMAX access networks in all four scenarios. Other messages used include hand-off initiate, hand-off acknowledge, proxy router advertisement, session information request, and release resources Internet Protocol control messages are integrated with WIMAX control messages to perform the fast handover protocol. | 05-28-2009 |
| 20090154397 | SYSTEM AND METHOD FOR PROVIDING QUALITY OF SERVICE ENABLERS FOR THIRD PARTY APPLICATIONS - System and method for providing quality of service enablers for third party applications are described. In one embodiment, the method comprises user equipment (“UE”) establishing a communications session with a third party application server hosting a selected third party application and receiving from the third party application server QoS information comprising at least one of a plurality of QoS attributes and configuring a QoS of a radio access network (“RAN”) in accordance with the received QoS information. The method further comprises activating the RAN QoS for the selected application; and establishing an application session with the third party application server via the RAN. | 06-18-2009 |
| 20090177735 | Unified communications systems and methods - Systems and methods for providing digital content are disclosed through a universal medial connection API, which include registering an application to be used during a session, loading policies to be used during the session, and identifying hardware features to be used during the session. These systems and methods also include steering data to be used during a session and presenting data to an endpoint during the session. The content is delivered from a first client to a second client according to the policies and hardware features that are available during the session. | 07-09-2009 |
| 20090185527 | Radio Resource Reservation for Wireless Networks - The present invention supports a communication protocol on a wireless communication network to allocate network resources. The radio network controller maintains quality of service (QoS) profiles. A serving node determines the type of application in a communication call and determines a QoS policy it transmits to the radio network. The radio network identifies the QoS profile based on the received policy and allocates network resources before announcing the call to an access terminal. | 07-23-2009 |
| 20090274090 | Push-To-Talk Optimization - A push to talk message protocol operating on a communication network between an originating and terminating communication device operates to transmit compressed message formats to initiate the push to talk message protocol. Four compressed session protocol message formats are used in the preferred embodiment. A compressed originating session initiation invite message is transmitted from the originating mobile station. A compressed terminating session initiation invite message is received by the terminating mobile station. A compressed session initiation protocol ping message is transmitted from the originating mobile station and received by the terminating mobile station. A compressed 200 OK session initiation protocol message is transmitted from the terminating mobile station and received by the originating mobile station. Finally, the originating mobile decompresses the 200 OK session initiation protocol message. These compressed massages are used to initiate the push to talk communication session. | 11-05-2009 |
| 20090313692 | KEY EXCHANGE FOR A NETWORK ARCHITECTURE - Provided is a method of providing secure communication between an initiator and a responder in a communication network. The method includes presenting a registration request with one or more proposals for dynamically establishing a security association between the initiator and the responder, and receiving a registration response indicating whether any of the one or more proposals have been accepted for the security association. | 12-17-2009 |
| 20110040886 | Method and System for Identification of Packet Gateways Supporting Different Service Types - The present invention provides a method and system for identification of the different packet gateways that support different types of services on their packet data networks. The method and system provides identification and addressing information to user equipment for one or more packet gateways that support different types of services, sometimes called QoS services. The identification and addressing information for the one or more packet gateways is provided in the present invention by and through a DNS server or an AAA server depending on the network architecture and the IP version supporting the communications with the mobile node. | 02-17-2011 |
| 20110090851 | Method and System for Transmission of Fragmented Packets on a Packet-Based Communication Network - The present invention provides a method and system for the identification and discovery of the lowest maximum transmission unit (MTU) size for transmission packets on some or all of the transmission path nodes. Different methods and protocols are described in the present patent application to support the identification and discovery of the lowest maximum transmission unit (MTU) size for fragmented transmission packets. | 04-21-2011 |
