| 20140362713 | QUALITY OF EXPERIENCE ENHANCEMENT FOR WIRELESS NETWORKS BASED ON RECEIVED SIGNAL STRENGTH AT A MOBILE DEVICE - Techniques are disclosed for network and/or evaluation and selection based on received signal strength at a device. For example, an received signal strength indicator (RSSI) can be measured (e.g., using Android API or other suitable methods). Then, the measured RSSI level can be compared against a threshold RSSI level, which can be determined on a device-by-device basis. In some embodiments, the RSSI values can assist the network evaluation and selection in certain situations, for example, where WiFi network quality is degraded because of locational movement and not backbone structure, and/or where there are multiple access points (APs) providing WiFi networks under the same SSID and each AP having different effective coverage. Further, in some embodiments, the RSSI values can provide the capabilities of WiFi AP suspension based on MAC addresses. In some embodiments, the RSSI values can be adopted to trigger QoE measurements. | 12-11-2014 |

| 20150023162 | EXTENDING DELAY TOLERANCE OF MOBILE APPLICATIONS FOR OPTIMIZING MOBILE TRAFFIC MANAGEMENT - Systems and methods for extending delay tolerance of mobile applications to optimize mobile traffic management are disclosed. In a mobile device, network stack timers or protocol stack timers are modified to extend delay tolerance of applications for radio alignment. In an embodiment, tolerance of mobile applications on a mobile device to delay in establishing a connection to a wireless network is extended by an application or a local proxy on a mobile device. Based on the tolerance that is extended, requests intercepted from the mobile applications are aggregated, over a period of time, such that transfer of the requests intercepted during the period of time is delayed. This minimizes the number of times the mobile device connects to the network, reducing the power consumption on the mobile device and unnecessary signaling in the network. | 01-22-2015 |
