Abstract

An method for improved transaction reservation in an Integrated Satellite Business Network. The method includes generating a transaction request message indicating the number of slots needed to transmit a data message. Then, the method includes transmitting the transaction request message to a host terminal, and assigning one or more slots within an inroute to the remote terminal. The method then includes transmitting a transaction assignment message containing the number of slots assigned and which slots were assigned. In response to this assignment, the method includes transmitting at least a portion of the data message during the slots assigned.

Claims

1. A method of improved transaction reservation in an integrated satellite network comprising:

generating a transaction request message in a requesting remote terminal from a group of remote terminals that contains information indicative of a number of slots needed to transmit a data message from the requesting remote terminal via a spacelink to a host terminal;

transmitting the transaction request message from the requesting remote terminal via the spacelink to the host terminal;

assigning, using the host terminal, one or more slots within an inroute to the requesting remote terminal;

transmitting a transaction assignment message that contains information indicative of a number of slots assigned and indicative of the one or more slots assigned from the host terminal via the spacelink to the group of remote terminals;

transmitting at least a portion of the data message during the one or more slots assigned from the requesting remote terminal via the spacelink to the host terminal;

queuing, after said transmitting of said transaction request message, a transaction request indicative of a number of slots needed to transmit said data message and of said requesting remote terminal having transmitted said transaction request message, the queuing including storing said transaction request at a bottom of a queue;

said assigning of said one or more slots including retrieving the transaction request from a top of said queue, and assigning said one or more slots in response to said transaction request; and

subtracting the one or more slots assigned from the number of slots requested and, in the event the one or more slots assigned is less then the number of slots requested, altering said transaction request to indicate a difference between the one or more slots assigned and the number of slots requested; and

requeuing said altered transaction request at a bottom of said queue.

2. The method of claim 1 further comprising:

assigning, using the host terminal, one or more additional slots within said inroute to said requesting remote terminal, including retrieving said altered transaction request from a top of said queue;

transmitting an additional transaction assignment message that contains information indicative of a number of additional slots assigned and indicative of the one or more additional slots assigned from the host terminal via the spacelink to the group of remote terminals; and

transmitting at least a further portion of said data message during the one or more additional slots assigned from the requesting remote terminal via the spacelink to the host terminal.

3. A method of improved transaction reservation in an integrated satellite network comprising:

generating a transaction request message in a requesting remote terminal from a group of remote terminals that contains information indicative of a number of slots needed to transmit a data message from the requesting remote terminal via a spacelink to a host terminal;

transmitting the transaction request message from the requesting remote terminal via the spacelink to the host terminal;

assigning, using the host terminal, one or more slots within an inroute to the requesting remote terminal;

transmitting a transaction assignment message that contains information indicative of a number of slots assigned and indicative of the one or more slots assigned from the host terminal via the spacelink to the group of remote terminals;

transmitting at least a portion of the data message during the one or more slots assigned from the requesting remote terminal via the spacelink to the host terminal;

said transmitting of said transaction request message from the requesting remote terminal via the spacelink to the host terminal including transmitting said transaction request message in a slot, selected by said requesting remote terminal, within a control aloha component of said inroute;

said assigning, using the host terminal, including assigning at least one slot within said inroute for a piggyback request message; and

transmitting, during at least one slot for said piggyback request message, said piggyback request message that contains information indicative of a number of additional slots, beyond those indicated in the transaction request message, needed to transmit said data message.

4. A method of improved transaction reservation in an integrated satellite network comprising:

receiving a data message into a remote network interface from a user device, the data message including a plurality of packets;

repackaging the plurality of packets into transaction packing units of a prescribed size and into residual slots;

generating a transaction request message that contains information indicative of an amount of bandwidth needed to transmit the data message from a remote network interface via a spacelink to a host network interface;

transmitting the transaction request message from the remote network interface via the spacelink to the host network interface;

assigning, using the host network interface, an amount of bandwidth within an inroute to the remote network interface;

transmitting a transaction assignment message that contains information indicative of an amount of bandwidth assigned from the host network interface via the spacelink to the remote network interface;

transmitting at least a portion of the data message during the bandwidth assigned from the remote network interface via the spacelink to the host network interface;

unpacking said transaction packing units and reassembling the data message; and

transmitting the data message to a host device.

5. The method of claim 4 including:

said generating of said transaction request message including generating said transaction request message that contains information indicative of a number of slots needed to transmit said data message;

said assigning including assigning at least one slot within the inroute to the remote network interface;

said transmitting said transaction assignment message including transmitting said transaction assignment message that contains information indicative of a number of slots assigned; and

said transmitting said at least said portion of said data message including transmitting said at least said portion of said data message during said slots assigned.
