A method of selecting a network from a plurality of available access networks is provided. The method includes identifying, by using a wireless user equipment, the plurality of access networks and identifying, by using a wireless user equipment, an invoked application. The method includes selecting, by using a wireless user equipment, a first access network from the plurality of access networks based, at least in part, on the application. A connection is established to the first access network in response to an application requirement. A handover procedure is invoked from the first access network to a second access network of the plurality of access networks in response to application requirements.

System, method, and computer-readable medium for user equipment decision-making criteria for connectivity and handover

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.

Embodiments of the present disclosure include techniques for optimization on downloading/streaming activities of media and/or other files (e.g., on a local client, or a local proxy on a mobile device). An example of such downloading/streaming is a user accessing media content including video and/or audio content using a mobile device such as a smart phone, a tablet, or a 'phablet,' etc.

Adaptive downloading or streaming to conserve mobile device or network resources

System and method of providing data to a mobile application accessible at a mobile device via different network connections without interruption are disclosed. The method, which may be implemented on a system includes, receiving data for the mobile application over a network connection different from a first network connection, and/or providing the data received over the network connection including any other data received from the first network connection, to the mobile application in a manner that is without interruption in data flow. The data is provided to the mobile application without interruption even when connections to the different network connections require change in IP addresses.

In one embodiment, a method comprises measuring a set of parameters for each of the available networks using an application layer protocol (e.g., HTTP). The method further comprises determining an overall quality level for each of the available networks based on the parameters, and choosing the network based on the overall quality level. In some embodiments, the set of parameters are measured by communicating with each of a plurality of predetermined servers within a respective network. Among other advantages, embodiments disclosed herein enable a quantified approach to user experience estimation and application-level Quality of Experience (QoE) measurements, which can serve as bases for selection of radios for the applications.

Radio or network evaluation for selection based on measurements using application layer protocols 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.

A method for performing a cell search routine commences by using the Synchronization Channel's (SCH) Primary Synchronization Code (PSC) to acquire slot synchronization to a cell (). This step will collect a number of hypotheses for frame timing. The method then uses a searcher algorithm such as a sequential dwell searcher that can quickly reject all of the wrong hypotheses gathered in the slot synchronization step, and determine the best hypotheses (). This cell search routine leads to faster cell acquisition times as compared to some prior art techniques. A receiver () that includes a cell searcher () that performs the method mentioned above is also described.

When communications are idle over all of the networks, one radio network may be assigned to be a primary radio network, and the alternate radio network may be switched off provided all incoming calls are routed to the primary radio network.
