Systems and methods for delivering digital content to a mobile device from a digital content provider are disclosed. Digital content is selected using a selection interface on the mobile device. The selected content is then transferred to a computing device by the digital content provider and subsequently transferred to the mobile device by the computing device. In some embodiments, the digital content is reformatted before being transferred to the mobile device. The digital content may be streamed from the computer system to the mobile device. A service provider of a network through which the mobile device connects to the digital content provider may bill a user of the mobile device on behalf of the digital content provider. The digital content provider may bill the user of the mobile device using a Premium SMS service.

Content delivery to a mobile device from a content service

Means for allowing users to manage and make productive use of PIM data are provided. User status is determined by certain contextual indicia whereby other parties may contact the user through the most appropriate means as reflected by that contextual indicia. Information concerning presence, status, location, availability and so forth are aggregated from various PIM sources and communicated to other parties who initiate contact with the user in light of the aggregated information. Various groups and permissions may be implemented with regard to the collection and sharing of information.

Context Based Action

A context aware data application presents information about a first user's contact means and methodologies. The application organizes, filters and present the information taking into account multiple inputs regarding the specific context and the relationship and preferred communication means between the first user and other users seeking to contact the first user. The information allows the users seeking to make contact to quickly take an action that is expected given the context of the first user as presenting the most relevant data allows the contacting users to take actions quickly and effectively.

Context aware data presentation

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.

Optimization of resource polling intervals to satisfy mobile device requests

Systems and methods of a 3D mobile user interface with configurable workspace management are disclosed. In one aspect, embodiments of the present disclosure include a method, which may be implemented on a system, of a three-dimensional, multi-layer user interface of a mobile device in a mobile network. User environment may include one or more layers or levels of applications, services, or accounts that are all easily accessible to and navigable by the user. For example, an indicator can be used to access a workspace in 3D representing a category or grouping of services or applications for the user. The user can customize or create a unique, non-mutually exclusive grouping, aggregation, or category of applications, services, accounts, or items. The grouping of indicators can be used to swiftly and efficiently navigate to a desired application, service, account or item, in a 3D-enabled user environment.

3d mobile user interface with configurable workspace management

A method for IP [=lnternet Protocol] communication between a mobile terminal and its correspondent node in a mobile radio network. The method comprises establishing (2-2) an IP connection between the mobile terminal and its correspondent node. After detecting a period of inactivity in the IP connection, (2-4) keep-alive messages are sent via the IP connection at predetermined intervals, which are varied. The method comprises monitoring (2-6) the lengths of several periods of inactivity at which the mobile radio network disconnects the IP connection. Based on the monitored lengths of periods of inactivity, a maximum interval (TINT) between keep-alive messages is determined (2-8) such that the maximum interval meets a predetermined criterion of statistical confidence, and the interval between keep-alive messages is set (2-10) to the maximum interval (TINT)-

Maintaining an IP connection in a mobile network

Systems and methods for dynamic adjustment of keep-alive message intervals in a mobile network are disclosed. One embodiment of maintaining an IP connection between a mobile terminal and a network node over a network includes, detecting a rate with which the client-slide request are made from the mobile terminal, detecting a rate with which the client-slide request are made from the mobile terminal, sending, by the network node, keep-alive messages to the mobile terminal in an absence of network traffic through the IP connection between the mobile terminal and the network node, and/or further optimizing the time intervals between the keep-alive messages based on a cost to send the keep-alive messages in the network.

A method for IP [=Internet Protocol] communication between a mobile terminal and its correspondent node in a mobile radio network. The method comprises establishing an IP connection between the mobile terminal and its correspondent node. After detecting a period of inactivity in the IP connection, keep-alive messages are sent via the IP connection at predetermined intervals, which are varied. The method comprises monitoring the lengths of several periods of inactivity at which the mobile radio network disconnects the IP connection.
