Abstract

In the future, pagers may support the IrDA protocol. IrDA is a set of standards that defines a serial infrared communications protocol. The IrDA protocol allows devices to communicate with each other over an infra-red (1R) port. For example, PDA's and PC's may contain IR ports and will both support the IrDA protocol. It follows that a typical application of IrDA would be for the PDA to dump its information to the PC to update schedules, address books, etc. Another example is using an IrDA compliant printer to print messages received by an 1rDA compliant pager.

AUTOMATIC PHONE NUMBER SELECTION FOR IrDA TRANSMISSION

by Juan Fernandez and Kenneth Lerner

BACKGROUND

  In the future, pagers may support the IrDA protocol. IrDA is a set of standards that defines a serial infrared communications protocol. The IrDA protocol allows devices to communicate with each other over an infra-red (1R) port. For example, PDA's and PC's may contain IR ports and will both support the IrDA protocol. It follows that a typical application of IrDA would be for the PDA to dump its information to the PC to update schedules, address books, etc. Another example is using an IrDA compliant printer to print messages received by an 1rDA compliant pager.

  In a pager, the IR port, in combination with IrDA features, will allow the pager to send and receive information between itself and an external device. An extremely useful feature in a pager would be the ability of a pager to send a received phone number to an external device. In particular, if the external device was a cellular phone, the pager user could return a call without dialing the phone number contained in the received message, as shown in Figure 1 below.

  A feature that allows a paging device to auto- matically select the phone number within a received message and transmit that phone number over the pager's 1R port is described below. The device receiving the IrDA transmission from the pager will typically be a cellular phone. The cellular phone may then dial the number within the received page. This feature is particularly useful when used with an alphanumeric pager, since a telephone number may be embedded within a long alpha message. Note that the external device need not be limited to a cellular phone. Transmitting a received phone number to a regular phone is also useful.

FIRST EMBODIMENT

1. The pager will identify the telephone number contained within a received message. This phone number may be 7 digits or 10 digits in length. It may also be preferable to select number strings which have a variable number of digits. This allows the pager to identify a phone extension, for example. The phone number will be selected from the string of characters within a message using software contained within the pager's microcontroller.

2. The pager will display the selected phone number within the received message when the message is read by the user. The phone number will be highlighted in some manner such as inverse video, brackets, different colors, or by some other manner.

3. After activating the feature via a button press sequence, the pager will offer the user an option to send the automatically selected phone number

over the IR port

4. If the user selects the option, the highlighted phone number will be sent over the IR port to the external device. The external device will then automat...
