Patent number: 8068835Abstract: Systems and methods are provided for processing wireless signal components for a mobile wireless access broadband service. This can include processes for measuring signal strength of an alternative frequency by tuning away from an existing frequency associated with an existing communications path. Such processes allow determining if the alternative frequency supports a subsequent communications path in a mobile broadband wireless application. Upon the determination, the process can automatically select the subsequent communications path based in part on the measured signal strength.Type: GrantFiled: October 27, 2005Date of Patent: November 29, 2011Assignee: QUALCOMM IncorporatedInventors: Nileshkumar J. Parekh, Fatih Ulupinar, Rajat Prakash

Patent number: 8005475Abstract: A wireless communications device is configurable to communicate with either one of two networks over a wireless medium, each of the two networks having a different air interface protocol. Additionally, the wireless device includes stored provisioning information for a set of networks of a first type and can map this first provisioning information into a second format for use with networks of a second type. The device also includes a non-volatile memory for storing default provisioning information so that some information remains available regardless of what is erased from the memory. The default provisioning information is enough to establish a connection over one of the available networks and allow reconstruction of a provisioning list.Type: GrantFiled: December 7, 2009Date of Patent: August 23, 2011Assignee: QUALCOMM IncorporatedInventors: Thadi M.

Patent number: 7978656Abstract: Systems and methodologies are described that facilitate maintaining consistent radio-link layer protocol (RLP) sequence numbers in the event of an RLP sequence number reset. An offset can be adjusted upon occurrence of the event to reflect a subsequent expected sequence number. The offset can be added to the RLP sequence numbers such that receiving devices and/or higher layer applications can operate without realizing the sequence number reset. Additionally, the offset can be synchronized among base stations to facilitate operability following handoff of the receiving device.Type: GrantFiled: March 25, 2008Date of Patent: July 12, 2011Assignee: QUALCOMM IncorporatedInventors: Nileshkumar J.
