Abstract

A communications system having a first server (205) with an electronic mail (e-mail) database for managing e-mail accounts, for storing radio device addresses associated with those accounts, and for storing electronic mail messages associated with those accounts. Each message has a header and text. A gateway connects the first server to a two-way radio network. A radio device (200) has a electronic messaging application. The radio device is capable of two-way communication over the two-way radio network. The first server comprises message handling software arranged to send, to the radio device, a portion of a message of a predetermined size, including a header portion and a text portion. The radio device (200) can request more of a message.

Claims

1. A communications system comprising:

a first server having an electronic mail (e-mail) database for managing e-mail accounts, for storing radio device addresses associated with those accounts, and for storing electronic mail messages associated with those accounts wherein each message has a header and text;

a gateway connecting the first server to a two-way radio network;

a radio device having a electronic messaging application, the radio device comprising a message generator and transmitter for generating a command and transmitting the command to the server over the two-way radio network to request a further portion of the text and being capable of two-way communication over the two-way radio network;

wherein the first server comprises message handling software arranged to send, to the radio device, a portion of a message of a user-selectable predetermined size, including a header portion and a text portion, the first server further maintaining a database of e-mail messages associated with e-mail account identifiers and the radio network comprising a second server maintaining a database of paging messages associated with pager addresses, and wherein the first server maintains a table correlating e-mail account identifiers with pager addresses.

2. The system of claim 1 wherein the radio devices comprises means for entering a filter parameter and sending a message to the first server including the filter parameter.

3. The system of claim 2, wherein the first server maintains filtering rules for selecting messages to be fed to the radio device according to a filtering parameter received from the radio device.

4. The system of claim 1 wherein the radio devices comprises means for entering a message length parameter and sending a message to the first server including the message length parameter.

5. The system of claim 4, wherein the first server maintains a message portion handling routine for feeding portions of messages to the radio device truncated in length according to the message length parameter.

6. The system of claim 1 wherein the first server further comprises means for generating a notification message for sending over the two-way radio network to a radio device having a given radio device address when a message is received at the server addressed to an e-mail account corresponding to that address.
