Patent number: 8060079Abstract: A method and system for prioritizing the optimization of sectors within a cellular network using the minimum least squares error (“MLSE”) algorithm is presented. Each sector's throughput and performance metrics are collected over time. Problem sectors are having one or more performance metrics above or below a specified acceptable value are identified. A MLSE algorithm is applied to problem sectors to determine a weight per metric. Next, for each problem sector, the optimized throughput is calculated by substituting the value of a specific problem metric with an acceptable value. Problem sectors are prioritized in order of how much their throughput would improve as a result of an improvement to the problem metric.Type: GrantFiled: September 12, 2007Date of Patent: November 15, 2011Assignee: Sprint Spectrum L.P.Inventors: Anoop Goyal, Jong-Hak Jung, Hemanth Balaji Pawar, Shilpa Kowdley Srinivas, Gustavo Enrique Ulffe Whu

Patent number: 7929490Abstract: Methods and systems for improving the paging of wireless communication devices (WCDs) are introduced. A radio access network (RAN) begins transmitting a series of paging messages to a WCD, and determines that the WCD is operating on a new carrier frequency. The RAN proactively continues the series of paging messages on the new carrier frequency, without waiting for the prescribed interval between paging messages to expire. Alternatively, the RAN proactively restarts the series of paging messages on the new carrier frequency, without waiting for the prescribed interval between paging messages to expire. Both of these embodiments serve to reduce the delay involved in paging WCDs. The RAN may condition its behavior based on the WCD's profile.Type: GrantFiled: March 27, 2008Date of Patent: April 19, 2011Assignee: Sprint Spectrum L.P.Inventors: Shilpa Kowdley Srinivas, Hemanth Balaji Pawar, Jong-Hak Jung, Anoop Goyal, Gustavo Enrique Ulffe Whu

Patent number: 7848238Abstract: Methods and systems are provided for using VoIP-quality metrics to dynamically adjust the EV-DO reverse activity bit (RAB). In one embodiment, an EV-DO access node provides VoIP service to EV-DO access terminals, which comprises (i) providing EV-DO service in a wireless coverage area and (ii) providing transport service over a packet-data network. The access node measures reverse noise rise (RNR) in the wireless coverage area. The access node further measures, over the packet-data network, each VoIP-quality metric in a set of one or more VoIP-quality metrics. The access node then determines whether to set or clear the RAB in the wireless coverage area based at least in part on the measured RNR and at least in part on the one or more measured VoIP-quality metrics.Type: GrantFiled: May 9, 2007Date of Patent: December 7, 2010Assignee: Sprint Spectrum L.P.Inventors: Hemanth Balaji Pawar, Shilpa Kowdley Srinivas, Anoop K.
