Abstract: 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.

Abstract: System and method of detection and management of user interactions with foreground applications on a mobile device in distributed caching are disclosed. One embodiment includes a method of mimicking, remote from the mobile device, timing characteristics of user activity with the mobile client, polling a content source for the mobile application based on the timing characteristics of the user interaction, on behalf of the mobile device and allowing responses cached on the mobile device for the user activity to be used until a change at the content source is detected, remote from the mobile device.

Abstract: Systems and methods for optimizing a polling interval to capture new or changed content at an application server in a wireless network are disclosed. In one aspect, embodiments of the present disclosure include a method, which may be implemented on a system, for polling the application server using a first polling interval, monitoring responses received from the polling of the application server, adjusting the first polling interval to a second polling interval for polling the application server and/or using the second polling interval for polling another resource delivering same or similar content as the application server.

Abstract: Systems and methods described herein employ techniques for generation and selective activation (or triggering) of network management policies in a congested network to, for example, prevent further aggravation of network congestion are disclosed. In order to address mobile network congestion it is necessary to be able to enforce network management policies on the devices which are in the a specific congested cell. This presents a challenge as the mobile devices cannot themselves determine if the cell they are currently located in is congested. Additionally, most network operators do not have mechanisms to determine which cells are congested in real-time. Thus, network operators (e.g., cellular providers) can create policies with congestion triggers that are not bound to specific cells to address congestion. The polices can be distributed to clients in the mobile network and selectively activated in congested cell locations (or areas) by the mobile clients.

Abstract: Systems and methods for mobile application traffic optimization are disclosed. In one aspect, embodiments of the present disclosure include a distributed proxy and cache system, including, a local proxy on a mobile device for intercepting a data request made via a mobile device, and a proxy server coupled to the mobile device and a content server to which the data request is directed. In one embodiment, the local proxy can forward the data request to the proxy server for transmission to the content server for a response to the data request. In addition, the proxy server sends the data request to the content server independent of activities on the local proxy and notifies the local proxy when changed or different content on the content server is detected for the data request.

One embodiment further includes, a system for managing handover from a first wireless connection to a second wireless connection for applications, the system including, a network interface operable to communicate with the first wireless network and the second wireless network, wherein the network interface is operable to receive first data from a first wireless network and receive second data for the application from a second wireless network and generate a continuous data flow for applications when handover from the first wireless network to the second wireless network occurs.

Abstract: Detection of network transactions or keepalives for maintaining long lived connections are disclosed. A keepalive detector can detect keepalive traffic based on keepalive parameters determined from an analysis of socket level network communication log data that record data transfer events including data sent from mobile applications or clients on a mobile device and data received by the mobile applications or clients on the mobile device, timing characteristics, protocol types, etc. Various statistical analyses can be performed on the network communication data to detect keepalives, taking into account variability in intervals of the data transfer events and sizes of data sent and received on each event. The keepalive detector can also detect keepalives from stream data on a mobile device by analyzing socket level communication messages including timing characteristics and amount of data transferred to detect keepalives and report keepalives using a data structure.

Abstract: An architecture for optimizing signaling for arbitrary proprietary and non-proprietary protocols. In one embodiment, a Transmission Control Protocol (TCP) stream is passed as a byte stream from an application to a local proxy over a first session, from the local proxy to a proxy server over a second TCP session, and from the proxy server to a content server over a third TCP session. The local proxy observes and identifies patterns within the byte stream, without being aware of the underlying protocol. Once a pattern is identified, the second TCP session is torn down such that the first TCP session replays the pattern to the application, and third TCP session replays the pattern to the content server. Once either side detects a change in the pattern, the second TCP session is re-established to deliver the changed content to the other end.

Abstract: Method and apparatus for provisioning an e-mail service to a mobile terminal in an e-mail system that uses e-mail addresses comprising a domain part. The apparatus maintains a list of good setting parameter sets versus e-mail domain parts. It receives an e-mail address and user authentication information from a user and compares the domain part of the received address with domain parts in the list of good parameter sets. If a match is found, e-mail service is provisioned with the matching parameter set. If no match is found, the apparatus requests and receives further parameters from the user, including an e-mail server address, and provisions the e-mail service with the further parameters. If the provisioning with the further parameters is successful, the domain part and the further parameters are used to generate a new setting parameter set in the list of good setting parameter sets.

Abstract: Systems of redundantly clustered machines to provide failover mechanisms for mobile traffic management and network resource conservation are disclosed. One embodiment includes a system of redundantly clustered machines to provide failover mechanisms for mobile traffic management and network resource conservation including, a first set of redundantly clustered machines coupled to a second set of redundantly clustered machines via a common repository node where each of the first and second set of redundantly clustered machines function independently to provide mobile traffic management or network resource conservation services. The first and second set of redundantly clustered machines can be physically located in different data centers or in the same data center.

Abstract: Techniques for temporarily and/or partially offloading mobile applications to one or more remote virtual machines in a server include establishing an application copy of a mobile application installed on a mobile device at a remote virtual machine, suspending the mobile application on the mobile device and offloading operations of the mobile application to the application copy at the remote virtual machine for a period of time. Suspending the mobile application and offloading its operations to the remote virtual machine for the period of time reduces consumption of resources on the mobile device. The virtual machine executes the application copy in the same manner the mobile device would execute the mobile application and transfers data from the execution to the mobile application at the end of the period of time to allow the mobile application to update itself and resume its operation without any loss of data or functionality.
