A method for distributing content in a communications network including obtaining () encrypted content, for example, from a content provider or from another subscriber terminal, obtaining () a rights object for the content, and in some embodiments obtaining an encrypted token based on the identity of the subscriber terminal obtaining the rights object, maintaining () a relation between the content and identity of the subscriber obtaining the rights object, and tracking () distribution of the content by the subscriber terminal that obtained the rights object in the content.

Digital content acquisition and distribution in digitial rights management enabled communications devices and methods

Methods and devices for end-user generation of content previews including selecting digital content stored on a communications device, and generating a content preview on the communications device from the digital content selected based on content transcoding information. In one embodiment, a mobile wireless communications device () includes a content preview generator () for generating content previews from content stored in memory based on content transcoding information, and a transmitter () for sharing the content previews with other mobile wireless communications devices, for example, in peer-to-peer communications.

Digital content preview generation and distribution among peer devices

An instant message (IM) proxy according to the present invention is capable of maintaining the availability status of a mobile subscriber even when the mobile subscriber is roaming or temporarily out of a mobile network coverage area, and even after the IM proxy unsuccessfully attempts to send an instant message to the mobile subscriber. Messages will continue to be re-sent to the mobile subscriber in the near-real time manner characteristic of a typical instant message system until IM parameters programmed into a retry counter and/or the timer located at the proxy are exceeded and the IM proxy drops the message. In addition, the IM proxy of the present invention is capable of bundling instant messages intended for the mobile subscriber to minimize mobile system overhead connection costs while at the same time minimizing IM system latency.

Instant message proxy for circuit switched mobile environment

A communication system provides real-time communication service such as instant messaging service and group chat service to a plurality of subscribers. The plurality of subscribers generates a plurality of real-time communication messages during a real-time communication session. The mobile station generates a message creation reference associated with a real-time communication message composed by one of the plurality of subscribers. The mobile station transmits the message creation reference and the real-time communication message so that the real-time communication message is arranged relative to the plurality of real-time communication messages during the real-time communication session based on the message creation reference.
