Abstract

A method for providing assured communications in a two-way wireless communications system is disclosed. An instruction is constructed at a first device for wireless transmission to a second device where the instruction is received by the second device and ultimately seen by the user. The instruction is transmitted as an instruction signal. The second device alters the instruction signal and transmits it back in altered form to provide an indication that the instruction has been received by the second device. The user of the second device informs the operator of the first device that the instruction has been seen by the user by transmitting a further altered version of the instruction signal to the first device. The disclosed method assures the operator of the first device that instructions are being received and acknowledged in a timely manner.

Claims

1. In a two-way wireless communications system adapted for use on the floor of a financial exchange, a method of providing bilateral assured communications, comprising the steps of:

constructing an instruction at a first device for wireless transmission as an instruction signal to a second device, the instruction signal including an instruction, an assigned sequence number for identifying the instruction, and an adjustable hierarchical value for identifying the stage of the instruction;

transmitting the instruction signal from the first device to the second device;

altering the instruction signal at the second device to provide an indication that the instruction has been received by the second device, the altering step including adjusting the hierarchical value to indicate the present stage of the instruction;

transmitting the altered instruction signal from the second device to the first device;

acknowledging receipt of the instruction by providing an indication that the received instruction has been seen by an operator of the second device, the step of acknowledging including further altering the previously altered instruction signal at the second device by further adjusting the hierarchical value to indicate the present stage of the instruction;

transmitting the further altered instruction signal from the second device to the first device;

acknowledging receipt of the instruction at the first device by again adjusting the hierarchical value to indicate that the first device has been informed that the operator of the second device has seen the instruction; and

automatically transmitting the again adjusted instruction signal from the first device to the second device.

2. The method of claim 1, including the additional step of:

the operator of the second device acting upon the instruction by one of trading a security and obtaining a quote on the security.

3. The method of claim 1, wherein the operator of the second device is a floor broker, the method including one of the following additional steps:

reporting to an investor that the instruction has been seen by the floor broker;

displaying the indication that the received instruction has been seen by the floor broker; and

constructing a further instruction at the first device for wireless transmission as a further instruction signal to the second device.

4. The method of claim 1, wherein the step of constructing includes entering data with a pen-type input device.

5. The method of claim 4, wherein the step of entering data includes one of checking a box, selecting from a list, and writing with the pen-type input device.

6. The method of claim 4, wherein the steps of altering and further altering the instruction signal includes stripping any image data.

7. The method of claim 1, wherein the instruction is one of a request for a stock quotation and an order to trade a stock.

8. The method of claim 1, wherein the instruction is a cancelation of an order to trade a stock.

9. The method of claim 1, wherein one of the first and second devices is a stationary terminal and the other is a mobile terminal.

10. The method of claim 1, wherein one of the first and second devices transmits an image of handwriting entered at the transmitting device.

11. In a two-way wireless communications system for use on the floor of a financial exchange, a method of providing bilateral assured communications, comprising the steps of:

constructing an instruction at a first device for wireless transmission as an instruction signal to a second device, the instruction being assigned a unique sequence number and a first hierarchical value;

transmitting from the first device to the second device the instruction signal along with the first hierarchical value;

assigning a second hierarchical value to the instruction at the second device indicative of the instruction having been received at the second device, the second hierarchical value being greater than the first hierarchical value;

transmitting from the second device to the first device the instruction signal along with the second hierarchical value;

assigning a third hierarchical value to the instruction at the second device indicative of the instruction having been seen by an operator of the second device, the third hierarchical value being greater than the second hierarchical value;

transmitting from the second device to the first device the instruction signal along with the third hierarchical value;

assigning a fourth hierarchical value to the instruction at the first device to indicate that the first device has been informed that the operator of the second device has seen the instruction; and

automatically transmitting from the first device to the second device the instruction signal along with the fourth hierarchical value.

12. The method of claim 11, wherein the sequence number for each instruction is unique and fixed regardless of any changes in hierarchical value assignments.

13. The method of claim 12, including the additional step of:

comparing at the first device the hierarchical value included in the instruction signal for that sequence number to the hierarchical value stored at the first device for that sequence number and updating the instruction to the hierarchical value level received.
