Publication number: 20130155918Abstract: A method includes, in response to a determination a received packet has information in a header of the packet that if modified with other information would allow a subsequent header compression to compress the header to a larger degree than if the information was not modified, modifying the information with the other information. The method also includes compressing at least the header and transmitting the packet including the compressed header. Another method includes, in response to a determination a received packet has a sequential identification in a header of the packet, modifying the sequential identification to a random identification; and transmitting the packet to a core network. Apparatus and program products are also disclosed.Type: ApplicationFiled: December 20, 2011Publication date: June 20, 2013Inventors: Ajoy K. Singh, Jay Jayapalan

Patent number: 7945255Abstract: A communication system, upon receiving an instruction to transfer deferrable data, determines whether an air interface is congested and, when the air interface is congested, defers a transfer of the deferrable data or transfers the deferrable, lower priority data as higher priority data. When, during a transfer of deferrable data, the system determines that the air interface is congested, the system may terminate the call and save a state of a partially completed deferred data transfer. Subsequent to the termination of the call, the system establishes another data connection over the air interface and transfers any remaining, not yet transferred deferrable data. In order to discourage subscribers from transferring higher priority data as lower priority data, the system may further restrict a transfer of lower priority data to designated time periods while allowing a transfer of higher priority data during the designated time periods and other time periods.Type: GrantFiled: August 12, 2008Date of Patent: May 17, 2011Assignee: Motorola Mobility, Inc.Inventors: John M.

Patent number: 7466675Abstract: The present embodiments address the need for a reduced resource dormant state for packet data systems (100) that substantially provides the benefits of current dormant mode operation but without the resource maintenance costs. After a period of MS session inactivity, PCF resources, certain PDSN resources, and the PCF-PDSN tunnel are released in order to enter a new reduced resource dormant state. When data arrives for a reduced-resource-dormant MS (101), PDSN-initiated messaging (303) is used to trigger the re-establish PCF resources, a PDSN-PCF tunnel connection (320), and released PDSN resources.Type: GrantFiled: January 16, 2004Date of Patent: December 16, 2008Assignee: Motorola, Inc.Inventors: Thomas B.

Publication number: 20070230438Abstract: A method and system for providing credit for participation in an ad hoc wireless communication network is useful for improving network efficiency. The method includes receiving at a first network node a first data packet transmitted from a second network node (step 305). The first data packet includes payload data and credit claim data. The first node then determines that the credit claim data should be forwarded to a credit accounting authority (step 310), so a second data packet is then transmitted from the first node to the credit accounting authority (step 315). The second data packet includes some of the credit claim data. The first node then transmits a third data packet to a third network node, where the third data packet includes the payload data (step 320).Type: ApplicationFiled: March 28, 2006Publication date: October 4, 2007Inventors: Jay Jayapalan, Stephen Magee

Publication number: 20070124735Abstract: A method and a system for scheduling requests generated for a plurality of mobile devices in a communication network (100) has been disclosed. The requests are generated for a transmission opportunity. The method includes computing a sort metric (302) for each request, based on an information update. A lead-time is then computed (304) with respect to a drop-dead time for each request, based on the sort metric for a time slice. The drop-dead time for a given time slice is the time before which scheduling has to be done so that data can be transmitted during the given time slice. Each request may be considered (306) for allocation in the time slice before the beginning of a next time slice, based on the lead-time.Type: ApplicationFiled: November 30, 2005Publication date: May 31, 2007Inventors: Suresh Kalyanasundaram, Rajeev Agrawal, Jay Jayapalan, Ivan Vukovic

Patent number: 7224674Abstract: To address the need for reducing wireless data transfer delay, an embodiment of this invention provides for a radio access network (RAN) (110) to transmit data, such as a data query, at the time of paging a dormant wireless unit (101). By transmitting the data at this time, wireless unit activity in response to the data can begin while the paging and traffic channel setup proceed. Thus, once established, the traffic channel will be idle for less time than under the present practice were data is not sent until the traffic channel setup is completed. Less idle traffic channel time is expected to improve channel utilization and contribute to lower packet data costs.Type: GrantFiled: March 28, 2002Date of Patent: May 29, 2007Assignee: Motorola, Inc.Inventors: John M. Harris, Sharon W. Tung, Jay Jayapalan
