According to embodiments described in the specification, a method, system and apparatus for managing transports is provided. The method comprises: maintaining a transport preference in a memory of the mobile electronic device, the transport preference including an identifier of a preferred transport; monitoring available transports; and selecting a transport for use based on the transport preference and the available transports.

Aspects relate to provision of enterprise call capabilities to mobile devices. For example, a mobile device can indicate, over a data channel, that a PBX is to make a call on its behalf to a called party. The PBX can call back the mobile device, call the called party, and bridge those call legs to establish the call. The mobile device can employ mechanisms that a particular incoming call is made by the PBX. These mechanisms can include using ANI information, sending, and receiving audible verification codes over the voice channel established after answering the incoming call. The verification codes can be selected based different behaviors of the mobile devices.

Error correction for DTMF corruption on uplink

In a method of processing an incoming sequence of one or more DTMF tones at a mobile device, the sequence is decoded to thereby identify any encoded message. Where the decoding does not identify a message, at least applying an error correction algorithm to the sequence to identify a message. Where the algorithm fails to correct the sequence, the sequence is compared to messages currently expected by the mobile device. If a message is not identified, a negative acknowledgement message may be sent. At a server, upon receipt of a negative acknowledgement message, it is determined if a message was sent to the mobile device in a previous pre-determined time window. If so, the message is re-sent. The server repeatedly sends certain messages to a mobile device until an acknowledgement message indicating receipt of the message by the mobile device is received.

DTMF signalling between mobile and server

A method, apparatus and system for handling a call received at a mobile communication device, in association with an automated number identification (ANI) number are provided. The ANI number is compared with a list of ANI numbers associated with an applications server, the list stored at the mobile communications device. When the ANI number is not in the list, a tone is provided on the call. When a corresponding tone is detected on the call in response to the tone, the call is handled as a call associated with the applications server and otherwise the call handled as a typical mobile communication call.

A wireless handheld device operable to continuously synchronize PIM information with a host desktop computer. The device comprises a software module for updating a handheld PIM database to reflect a change to PIM information, a software module for updating a handheld mirror database to reflect the change to PIM information, a software module for generating a PIM message relating to the change to the PIM information, a software module for translating the PIM message from a handheld data format into a network data format and a software module for sending the PIM message from the client wireless handheld device to the host desktop computer via a wireless network.

Systems and methods for continuous PIM synchronization between a host computer and a client handheld device

A method, system and computer-readable product for a fixed mobile convergence system. The method includes analyzing at least one rule set associated with at least one user profile with the user profile being associated with at least one mobile device supporting more than one line. Each line offering one or more transports and options for establishing a telephone call. After analyzing the one or more rule sets, a context-specific real-time usage mode is determined based on the analysis which include selections of a telephone line, a transport and establishment options. After determining the usage mode, a call is established between one of the devices and a telephony endpoint, either incoming or outgoing, based on the determined usage mode.

User profiles

A system and method for generating runtime metadata for use in the development of mobile device applications. A metadata file, such as an XML file that is used to capture the metadata for a database associated with a mobile device application, is used to generate initialization code. This initialization code, when executed, creates runtime metadata for the application database in terms of a first object (e.g. classID object) through which metadata associated with the application database is accessible and at least one second object (e.g. propertyID object) through which metadata associated with a property of a data record of the application database is accessible.
