Abstract

Chat messages are communicated with a plurality of wireless, including one or more wireless devices, over corresponding communication links. The present invention determines link latency associated with communicating a message with at least one wireless device and adjusts transmission timing of chat messages based on the link latency in order to provide orderly communication of chat messages.

Claims

1. A method of communicating messages with a plurality of client devices that include one or more wireless devices over a communication link, comprising:

determining a link latency associated with communicating a message with at least one wireless device; and

adjusting transmission timing of chat messages based on said link latency in order to provide orderly communication of chat messages.

2. The method of claim 1, wherein the link latency corresponds to a delay associated with communicating a message with at least one wireless device.

3. The method of claim 1, wherein the transmission timing of the chat messages is adjusted by delaying a chat message transmission in accordance with a time reference derived from the link latency.

4. The method of claim 1, wherein the transmission timing of the chat messages is delayed such that the chat messages arrive at the plurality of client devices at substantially the same time.

5. The method of claim 1, wherein the link latency is determined using a low level network protocol.

6. The method of claim 1, further including:

informing a client device with slowest link latency of a link latency of a next slowest client device;

transmitting a message from the client device with the slowest latency to other client devices with a delayed link latency that is based on the link latency of the next slowest client device; and

displaying a chat message originated at the client with slowest latency after a delay that accounts for the delayed link latency.

7. The method of claim 1, wherein said latency measurement is repeated over time.

14. The communication system of claim 1, wherein said latency measurement is repeated over time.

8. A communication system that communicates chat messages with a plurality of client devices wireless device over a communication link, comprising:

a chat server that creates a chat room session for the plurality of client devices;

a wireless network that communicates messages addressed to at least one wireless device, wherein the chat server determines a link latency associated with communicating a message with the at least one wireless device and adjusts transmission timing of chat messages based on said link latency in order to provide orderly communication of chat messages.

9. The communication system of claim 8, wherein the link latency corresponds to a delay associated with communicating a message with at least one wireless device.

10. The communication system of claim 8, wherein the transmission timing of the chat messages is adjusted by delaying a chat message transmission in accordance with a time reference derived from the link latency.

11. The communication system of claim 8, wherein the transmission timing of the chat messages is delayed such that the chat messages arrive at the plurality of client devices at substantially the same time.

12. The communication system of claim 8, wherein the link latency is determined using a low level network protocol.

13. The communication system of claim 8, wherein a client device with the slowest link latency is informed of a link latency of a next slowest client device, wherein the chat server transmits a message originated from the client device with the slowest latency to other client devices with a delayed link latency that is based on the link latency of the next slowest client device.
