摘要:
Methods, devices, and computer readable media for switching communications from a first messaging protocol/service to a second messaging protocol/service by use of messaging information being embedded in a header of a first message of the first messaging protocol/service to enable the recipient to contact the sender over the second messaging protocol/service, is provided.
摘要:
A contact is determined to be unavailable if a predetermined period of time has elapsed since an instant message was sent to the contact and an expected notification for the instant message was not received during that predetermined period of time by the device that sent the instant message. If the expected notification is a delivered notification, then the contact is deemed unreachable. If the expected notification is a read notification and a delivered notification for the instant message has been received by the device that sent the instant message, then the contact is deemed busy.

To promote efficient transmission of presence update information to a presence service client associated or integrated with a communication client such as an instant messaging (IM) client, a separate computing device may be notified when the communication client becomes dormant. The separate device may buffer presence updates destined for the communication client, each presence update containing information regarding availability of at least one of a set of contacts for intercommunication via said communication client. When the separate device learns that either the communication client has ceased being dormant or that an event has occurred which shall cause the communication client to cease being dormant, the buffered presence updates may be sent to the presence service client. Presence updates within the buffered set may be reconciled to eliminate obsolete information. The result may be a conservation of wireless connection bandwidth or reduction in device power consumption.

A method, server and system for managing the delivery of email messages in multiple parts is provided. A method for sending email messages in multiple parts to a mobile communication device, comprises receiving a request for additional content from a mobile communication device in respect of an email message for which a selected part of the content has been previously sent to the mobile communications device; and determining if processing technology used to provide the previously sent selected part is compatible with currently available processing technology, and if compatible then processing additional content from the email message using the currently available processing technology and sending the processed additional content to the mobile communication device.
摘要:
A mobile communication device operable to automatically send a notification of a status change within a messaging session. The device includes a processor operable to execute a real-time messaging application on the mobile communication device, an input module operable to receive a session status change instruction from a user and a status update module operable to generate a session status change message responsive to receipt of the session status change instruction from the user. The device further includes a transceiver operable to communicate with a plurality of remote devices and operable to automatically transmit the session status change message to each one of a group of at least two remote real-time messaging applications responsive to the generation of the session status change message by the status update module.
摘要:
The approximate location of a directed cell of a cellular network is calculated based on locations in the vicinity of which mobile devices were able to detect the directed cell. A mobile device is able to estimate its own location from the approximate locations of one or more directed cells that it can identify. This estimated location of the mobile device may be used to seed its GPS receiver.
摘要:
There is provided a method of changing a theme for a user interface of a computer system comprising receiving an identification of an image with which to define a color palette of a theme for rendering elements of a user interface on a color display of the computer system; analysing the image to determine at least one predominant color; and defining the color palette in response to the analysis. The image may comprise a background image selected by a user for display by the computer system. Dynamic generation of the color palette matches the user interface to colors to provide flexible and appealing themes. A computer readable memory having recorded thereon instructions to carry out this method is also provided, as well as a device comprising such memory.
摘要:
A method of displaying a map on a wireless communications device includes steps of obtaining map data for rendering the map to be displayed on the wireless communications device, generating corrected map data by applying a spherical correction factor to the obtained map data, and rendering the corrected map data to display the map on a display of the wireless communications device. The spherical correction factor corrects for map distortions that occur at northerly (or southerly) latitudes. Since the spherical correction factor is a simple correction to a 3×3 transformation matrix, this spherical correction can be easily applied without taxing the CPU limitations of small handheld devices.
