A method for securely transferring a service from a first mobile device to a second mobile device, the service being associated with a server configured for facilitating provisioning of services to mobile devices over a wireless communications network. The method includes generating in the first mobile device a shared key, the shared key being generated using a master key unique to the server and to the first mobile device, the master key being accessible by the server and by the first mobile device; and sending said shared key from the first mobile device to the second mobile device using an alternate communication mechanism independent from the server.

Method of securely transferring services between mobile devices

An attachment server network including at least two attachment servers in communication with one another, each of the attachment servers for converting email attachments in response to view requests received from portable electronic devices, each of the attachment servers having a respective cache for storing data corresponding to previously converted attachments, the data being available to any of the attachment servers in the attachment server network.

A method for content-based presence communication entails receiving presence information, storing the presence information in any arbitrary data format, validating a subscription request to subscribe to the presence information by determining if information contained within the subscription request represents an authorized subscription relationship, and communicating the presence information when the presence information matches the subscription expression.

Content-based publication-subscription system for presence information

A method, performed by a registrar of a presence service, for registering a user with a presence service. The method entails negotiating a key with a client device operated by the user in order to establish an encrypted communications channel between the client device and the registrar via a proxy node, authenticating the user by exchanging messages through the encrypted communications channel and through a separate e-mail channel, binding a universally unique identifier identifying the user with one particular function node that is interposed between the proxy node and a publish-subscribe subsystem of the presence service and creating a user profile for the user and storing the user profile in a persistent data store.

A method for managing a subscription to content-based presence information entails receiving a subscription-suspension message from a device at a presence service, identifying the subscription associated with the subscription-suspension message, suspending the subscription, and sending a response from the presence service to the device to notify the device that the subscription has been suspended. Suspending the subscription may involve accumulating notifications in a persistent data store. The method may further involve receiving a subscription-resumption message at the presence service to resume the subscription that was suspended.

Subscription management for a content-based presence service

A method for providing wavetable information to a wireless device from a content server over a wireless network, the wavetable information including a plurality of samples corresponding to a plurality of notes, comprising: in response to a request from the wireless device, receiving at a proxy server the wavetable information from the content server; filtering the wavetable information in accordance with a selection of samples contained in the request; and, transmitting the filtered wavetable information to the wireless device.
