Abstract

A radio paging network transmits non-paging data, such as facsimile images, to lap top computer receivers by formatting the data into a series of packets and interleaving these packets, on a space available basis, into the paging signal.

Claims

1. A paging method comprising:

maintaining first and second data gueues, the first queue containing paging message data and the second queue containing secondary, no-paging message data, such datum in the first and second gueues additionally including a recipient identifier code identifying the recipient for which the datum is intended; and

formatting the data from the first queue into a time slot transmission format, said formatting further including interleaving data from the second queue into said time slot transmission format on a time available basis, wherein data from the second queue is interleaved into time slots that are devoid of data from the first queue.

2. The paging method of claim 1 in which the formatting step includes providing each time slot in the time slot transmission format with a datum identifying that time slot.

3. The paging method of claim 1 which further includes providing facsimile data to the second queue.
