摘要:
A system and method for pushing information, such as calendar event messages, from a host system to a mobile data communication device upon sensing a triggering event is disclosed. A redirector program operating at the host system enables a user to continuously redirect calendar event messages, such as meeting reminders and notices, from the host system to the user's mobile data communication device upon detecting that one or more user-defined triggering events has occurred. The redirector program operates in connection with event generating applications and repackaging systems at the host system to configure and detect a particular user-defined event, and then to repackage the calendar event messages in an electronic wrapper prior to pushing the data items to the mobile device. An optimized data structure for storing the calendar event messages is also provided.

A method and system in a data communication environment enables the exchange of information between a plurality of software applications through a selected communication device, such as a radio frequency modem. Messages received by modem are stored as files intended for one of a plurality of applications, even if the destination application is not currently active. The method and system may utilize the file system of the transmitting location to provide the address of the receiving location by embedding the address in the path of the file to be transmitted.

There is provided a multi-tap keyboard user interface with auditory feedback. In one embodiment, there is provided a method for controlling operation of a mobile device having a plurality of input devices, comprising associating groups of one or more keys of the input devices to define at least one input region and in response to an input received from said input devices, performing an associated action for operating the device, responding equally to any input from a same input region. A repeated input (multi-tap) to a same input region cycles through a plurality of actions associated with the input region. Auditory feedback comprising a vocalized description of the action is provided. The multi-tap keyboard user interface with auditory feedback may adapt a mobile device (e.g. PDA or smart phone) for use by visually impaired users.

摘要:
A wireless communication system includes mobile devices and a local area network. Local base stations are coupled to the local area network. Each base station has a unique address on the network and is configured to transmit and receive data packets to and from the mobile devices and to transfer the data packets between local base stations over the network using the unique address. A subscription server operates on the network. The subscription server is configured to store data identifying the unique address of the local base station covering each of the mobile devices. The subscription server is further configured to enable the local base stations to locate any one of the mobile devices. A redirection software module is configured to send and receive data packets over a wide-area wireless network to and from mobile devices that are not within range of any of the local base stations.
摘要:
Methods and apparatus for increasing security and control of voice communication sessions, such as Push-To-Talk (PTT) over Cellular (PoC) sessions, using digital certificates are disclosed. A certificate control mechanism of a private communication network is used to help facilitate secure PoC sessions for mobile communication devices associated with the private network. The certificate control mechanism of includes a certificate controller which is adapted to communicate with a Certificate Authority (CA) component which produces and stores a plurality of digital certificates for the mobile devices. The certificate controller is further adapted to communicate with one of a PoC server and a PoC group list server through a public communication network (e.g. the Internet) so as to provide the plurality of digital certificates for secure PoC communication sessions for chat groups which include the plurality of mobile communication devices. In one illustrative technique, a request message for participation in a PoC session is received by an authentication component of a PoC server from a mobile device. The request message is signed with use of a private key of a digital certificate which may be associated with the mobile device, an end user of the mobile device, or a chat group which includes the mobile device. An authentication procedure is performed on the request message by the authentication component. The authentication procedure includes retrieving a public key associated with the digital certificate and attempting to validate the signature with use of the public key. Processing for the PoC communication session is permitted for the mobile communication device if the authentication is successful, and otherwise denied. Several other techniques and variations are described.
摘要:
A device and a method of responding to a received interrupt event received by a communication device is provided. The method comprises accessing data associated with a calendar application and/or a location application to determine a current state of availability of a user of the device using data; determining whether a response action is to be sent in response to the event when the device is note available; and sending the response action. The device incorporates modules to perform the method.
摘要:
A novel apparatus and method for changing the behavior of an electronic device is provided. In an embodiment, an electronic device includes the functionality of a cellular phone, a voice mail system and a calendar application. The device is configured to use the calendar application to determine whether to direct a phone call to the user or whether to instantly direct the call to voice mail.
