Abstract: Methods and systems are directed toward enabling a user of a target device, such as a mobile device, to register for automatic initiation of a messaging service on the target device. A target device user interface, such as a login user interface, provides a selectable activation element for the user to indicate that future messaging sessions with the target device should be established automatically. An activation indicator and target identifier are associated with a user identifier and stored in a messaging system data store. When the user ceases use of a messaging session on another device, such as a general purpose computing device, the messaging system uses the user identifier and target identifier to automatically establish a corresponding messaging session on the target device. The user of the target device may then hold a messaging session with an existing third party device or with a different third party device.

Abstract: A system, apparatus, and method are directed to managing automatic sign in to an Instant Messaging (IM) session on mobile device from another computing device, such as a personal computer (PC), over a network. The end-user of the PC may provide an account identifier, password, and the like, and in response, receive a cookie, that may further include the account identifier, encoded string, and the like. The end-user may then request initiation of the IM session using a toolbar selection, a script, applet, form, web page selection, and the like. As part of the request, the cookie may be provided to the server. If the request is authenticated based, in part, on the cookie information, the server uses the account identifier to locate an associated a mobile device identifier. The mobile device identifier is employed to log the end-user automatically into the mobile device.

Abstract: Two-way communication between a general purpose computing device, such as a PC, and a mobile terminal, such as a cell phone. The general device executes a conversation user interface through which a user enters a message. The message is sent to an intermediary communication service, such as a portal server, along with a mobile terminal identifier, such as a phone number. The intermediary service creates a mapping between the mobile identifier, a general device user identifier, and an extension to an intermediary device identifier, such as an extension to an SMS short code. The intermediary service sends the message to the mobile terminal along with the intermediary service identifier and the extension. The mobile device returns a response with the mobile identifier, the intermediary service identifier, and the extension. The intermediary service uses the mobile identifier and the extension to determine the general device user identifier and send the response.

Abstract: A system and method are directed towards providing a user interface for controlling a communication mode of a client device. The interface enables a user to set a presence and/or a communications mode, which the client device communicates to other devices directly or via an intermediary server. The presence generally reflects the user's availability, communication capability, desire to communicate, and the like. The presence can be directly or indirectly associated with the communication mode, which can comprise SMS, IM, email voice, and the like. The interface includes a contact list an enables the user to select a mode to communicate with a contact. The communication modes associated with each contact can also be incorporated into and displayed in an email address book. The interface also indicates the communication mode of each incoming and outgoing message in conversations with one or more other client devices.

Abstract: A first device running a messaging application, such as an instant messaging (IM) application, engages in messaging communication with a remote device running a browsing application. The remote device user is not associated with the messaging network of the first device. The first device sends an instant message directed to the remote device. The remote device is addressed using a means other than the addressing means used in the IM community associated with the first device, such as the MSISDN number of the remote device. The message is processed so that it may be displayed on the remote device by way of the browsing application. The user of the remote device may reply to the message using the browsing application, in which case the reply message is processed and forwarded to the first device, where it is converted into the IM format for display within the IM application.

Abstract: A network device, method, and mobile device are directed towards enabling a user to compose a message using an email interface, and then to send the message to a recipient as a text message. The message is automatically converted into one or more SMS, EMS, MMS messages, or the like. In addition, any attachments in the message may be converted to a URL link the enables the recipient to access the attachment. When the user sends the text message, a copy of the message may be placed in the user's email sent folder. If a response is received as a text message, it may be converted to an email message. In addition, the response message may be moved to the user's email inbox folder. A notification of its receipt may also be provided to the user through the email interface.
