Abstract

An instant messaging terminal manages multiple conversation sessions across multiple instant messaging services. The terminal includes a display for conversation session windows, a data entry device, a communications module for wireless network communication, and a control module for coordinating network access and controlling conversation session management. The data entry device includes programmable keys for emoticons and the control module automates the generation of a key sequence for generation of a graphical symbol that is compatible with the service being used by a message recipient.

2. The terminal of claim 1, the data entry device further comprising:

a plurality of keys for graphical symbols, each graphical symbol key including indicia identifying the graphical symbol generated by depressing the key bearing the indicia.

3. The terminal of claim 2, the data entry device further comprising:

at least one programmable key associated with a set of characters corresponding to a graphical symbol supported by an instant messaging service provider.

4. The terminal of claim 3, wherein the control module generates, in accordance with an instant messaging protocol being used to communicate with a buddy, a character sequence corresponding to the graphical symbol in response to the depression of the programmable key being depressed.

5. The terminal of claim 1 wherein the control module and the communications module detect a beacon being received by the wireless transceiver of the instant messaging terminal.

6. The terminal of claim 5 wherein the control module prioritizes the detected beacons by strength of detected signal.

7. The terminal of claim 6 wherein the control module detects a beacon advertising its identifier.

8. The terminal of claim 7 wherein the control module detects an access point request for a security key.

9. The terminal of claim 8 wherein the control module generates a prompt for a security key in response to the detection that a security key is requested.

10. The terminal of claim 9 wherein the control module stores a profile containing network settings for a network communicating with the communications module and the wireless transceiver through an access point.

11. The terminal of claim 1 wherein the control module accesses at least one instant messaging service provider through the access point.

12. The terminal of claim 11 wherein the control module generates a buddy list identifying buddies coupled to each instant messaging service accessed by the control module and displays the buddy list in response to a buddy list key being depressed on the data entry device.

13. The terminal of claim 12 wherein the generated buddy list displays the buddies with whom active conversations are being conducted as an active buddy list and displays the buddies with whom no active conversations are being conducted following the active buddy list.

14. The terminal of claim 13 wherein the control module generates and displays a conversation session window for each active buddy in the active buddy list.

15. The terminal of claim 14 wherein each of the conversation session windows generated by the control module includes a header that identifies the active buddy with whom a conversation is being conducted, the number of windows being displayed, and the total number of active conversations.

16. The terminal of claim 15 wherein the control module parses characters entered with the data entry device and confirms the entered characters are compatible with the instant messaging service coupled to the communications module and wireless transceiver through the access point.

17. The terminal of claim 1 wherein the control module includes an audio player for generating sound from a downloaded file.

18. The terminal of claim 17 wherein the audio player of the control module downloads and stores audio files in a memory coupled to the processor within the terminal housing.

19. The terminal of claim 17 wherein the audio player of the control module generates sound from files received from an Internet radio station through a wireless, Internet protocol access point.

20. A method for managing wireless network access and instant messaging through a wireless access point with a handheld instant messaging terminal comprising:

entering textual characters and graphical symbols with a data entry device of a handheld terminal to form instant messages for delivery to an instant messaging service;

displaying the entered textual characters and graphical symbols on a display of the handheld terminal;

communicating instant messages with a wireless, Internet protocol access point, the instant messages being communicated with a communications module and wireless transceiver in the handheld terminal;

coordinating authentication for coupling the handheld instant messaging terminal to a local network through the wireless, Internet protocol access point;

implementing instant messaging and sessions protocols to control a conversation session through the wireless, Internet protocol access point, the instant messaging and session protocols being implemented within the handheld instant messaging terminals;

displaying conversation histories for active conversations terminated by a loss of a network connection; and

automatically searching for wireless, Internet protocol network beacons after the conversation histories are displayed.

21. The method of claim 20, the conversation session control further comprising:

identifying a key on the data entry device with a graphical symbol that is generated by depressing the key.

22. The method of claim 21, the conversation session control further comprising:

associating at least one programmable key with a set of characters corresponding to a graphical symbol supported by an instant messaging service provider.

23. The method of claim 22, the conversation session control further comprising:

generating in accordance with an instant messaging service protocol being used to communicate with a buddy, a character sequence to represent the graphical symbol supported by the instant messaging service provider in response to the depression of the programmable key.

24. The method of claim 20, the conversation session control further comprising:

detecting a beacon with the handheld instant messaging terminal.

25. The method of claim 24, the conversation session control further comprising:

prioritizing detected beacons by strength of detected signal.

26. The method of claim 25, the conversation session control further comprising:

detecting a beacon advertising its identifier.

27. The method of claim 26, the conversation session control further comprising:

detecting an access point requesting a security key.

28. The method of claim 27, the conversation session control further comprising:
