Communications transactional message handling
First Claim
1. A communications system in which a first terminal is operative to send a transactional message to a second terminal and in which said second terminal is operative to send an acknowledgement of receipt of said transactional message to said first terminal followed by a transactional response to said first terminal;
- in which the improvement comprises said second terminal being configured to skip sending said acknowledgement to said first terminal and to send said transactional response in place of said acknowledgement, said first terminal being configured to examine the form of said transactional response and said first terminal being configured to accept said transactional response as indicative of receipt of said transactional message by said second terminal if said transactional response is in a correct form.

Abstract
In a communications system, in the embodiment, a satellite communications system, transactional messages 28 36 are exchanged between the user terminal 14 and a base station (earth station) 16 via a communications satellite 10 in order to set up and maintain the progress of a call, encompass occasional user terminal registration and position estimation, allow call termination and attend to a host of other housekeeping processes. The prior art required the sending of acknowledgement messages 32 between transactional messages. The invention replaces the sending and requesting of acknowledgement messages 32 with an each-end recognition of the style of transactional responses as an ipse facto acknowledgement, thereby much speeding up the transactional message and transactional response/message exchange, so releasing time resources to the system.

8. A first terminal, in a communications system, operative to send a transactional message to a second terminal, where said second terminal is operative to send an acknowledgement of receipt of said transactional message to said first terminal and is thereafter operative to send a transactional response to said first terminal;
- in which, when said second terminal is operative to skip sending said acknowledgement to said first terminal and to send said transactional response in place of said acknowledgement, said first terminal is operative to examine the form of said transactional response, and to accept said transactional response as indicative of receipt of said transactional message by said second terminal if said transactional response is in a correct form.

15. A second terminal, in a communications system, wherein a first terminal is operative to send a transactional message to said second terminal, where said second terminal is operative to send an acknowledgement of receipt of said transactional message to said first terminal and where said second terminal is thereafter operative to send a transactional response to said first terminal;
- in which said second terminal is configured to be operative to skip sending said acknowledgement to said first terminal and to send said transactional response in place of said acknowledgement and for said first terminal to examine the form of said transactional response and to accept said transactional response as indicative of receipt of said transactional message by said second terminal if said transactional response is in a correct form.

22. A method for operating a communications system wherein a first terminal is operative to send a transactional message to a second terminal and wherein said second terminal is operative to send an acknowledgement of receipt of said transactional message to said first terminal and is thereafter operative to said a transactional response to said first terminal;
- said method comprising the steps of;
causing said second terminal to skip sending said acknowledgement of said first terminal, causing said second terminal to send said transactional response in place of said acknowledgement, causing said first terminal to examine the form of said transactional response, and causing said first terminal to accept said transactional response as indicative of receipt of said transactional message by said second terminal if said transactional response is in a correct form. - View Dependent Claims (23, 24, 25, 26, 27, 28)
