A method and system for distributing data between a first user and a second user by detecting direct or indirect communication between the first user and the second user, creating an entry for the second user in a roster for the first user, populating the entry for the second user in the roster of the first user with data elements and attributes of the data elements, the data elements and attributes of the data elements indicating what data can be shared with the second user and how the data is to be shared and utilizing the roster of the first user to distribute data reflecting the first user to the second user.

Method and system for distribution of presence information

Graphical user representations, such as emoticons or avatars, used to convey mood and emotion, can be dynamically modified and manipulated, e.g. by squeezing, rotating, distorting, coloring, etc. This enables a user to customize or tailor an existing emoticon to better reflect the user's current mood or emotion. For example, a user may insert a smiley face emoticoninto a text message and then manipulate or distort the face or a component of the face (e.g. the smile) to broaden the smile into a grin, or twist the smile into an ironic smile, etc. This enables the user to personalize the emoticon rather than having to select the most appropriate emoticon from a palette of predefined emoticons. Another aspect is device hardware (e.g. dedicated or shared user interface elements or specific touchscreen gestures) for recognizing the squeezes or other gestures that are meant to modify or manipulate the emoticon.

Dynamically manipulating an emoticon or avatar

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.

Method and system for registering a presence user with a presence service

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 of transmitting interleaved real-time and non-real-time data on a packet based network so as to provide voice Quality of Service comparable to the Time Division Multiplexing realm of traditional telephony. The method reduces packet jitter and delay by employing separate queues for the different types of data as well as through the use of jitter buffers. The interleaving method consists of a number of discrete concepts and mechanisms that when used together in the manner disclosed herein provides consistent high-quality transmission of real-time data over packet/frame/cell-based networks. The elements required for this method include time-slot co-ordination, a dynamic MTU algorithm, and a Multiple queue egress traffic management system.
