Abstract

Techniques are disclosed for improving management of user information in instant messaging systems. Expiration criteria are defined, whereby one or more users or user groups may be considered as having “expired” from consideration by instant messaging functions such as presence determination. In particular, instant messaging activity is preferably used as an expiration criterion. Absence of inbound or outbound messages for a specified amount of time (or since a particular date/time) can therefore be used as a trigger for treating a user or group of users as expired. As a result, efficiency of an instant messaging system is improved by omitting the expired users and groups from subsequent management operations. Optionally, an expired user or group may be revived upon occurrence of certain events (such as a newly-arriving instant message from, or a change in presence status of, the user or group). “On-demand” expiration and revival are preferably provided as well.

Claims

1. A computer-implemented method of managing user information in an instant messaging (“

IM”

) system, comprising;

determining, for an IM client that is operably connected to the IM system, whether any of a plurality of users remembered for the IM client should be treated as expired due to absence of communication with the IM client; and

performing a presence detection function of the IM system to determine current presence status on behalf of the IM client, comprising;

for each one of the plurality of users for whom the determining determines that the user is to be treated as expired, omitting this user as a remembered user when the presence detection function determines the current presence status, but not deleting this user from the plurality of users remembered for the IM client; and

including all others of the plurality of users as remembered users when the presence detection function determines the current presence status.

2. The method according to claim 1, wherein the determining uses expiration criteria selected by a user of the IM client to determine whether any of the users remembered for the IM client should be treated as expired.

3. The method according to claim 1, wherein the determining compares a first date when an instant message last arrived from each particular one of the users remembered for the IM client to a second date selected by a user of the IM client to determine whether any of the users remembered for the IM client should be treated as expired.

4. The method according to claim 1, wherein the determining comprises determining whether an instant message last arrived from each particular one of the users remembered for the IM client more than a specified length of time before a current time to determine whether any of the users remembered for the IM client should be treated as expired.

5. The method according to claim 1, wherein the determining compares a first date when an instant message was last sent by a user of the IM client to each particular one of the users remembered for the IM client to a second date selected by the IM client user to determine whether any of the users remembered for the IM client should be treated as expired.

6. The method according to claim 1, wherein the determining comprises determining whether an instant message was last sent by a user of the IM client user to each particular one of the users remembered for the IM client more than a specified length of time before a current time to determine whether any of the users remembered for the IM client should be treated as expired.

7. The method according to claim 1, wherein the determining enables a user of the IM client to select at least one of the plurality of users remembered for the IM client that will then be automatically treated as currently expired.

8. The method according to claim 1, wherein the determining is performed by analyzing expiration information for each presently-unexpired one of the plurality of users remembered for the IM client upon occurrence of a configured interval.

9. The method according to claim 1, wherein the determining and omitting are also performed for user groups remembered for the IM client.

10. The method according to claim 1, further comprising:

receiving an inbound message from a particular one of the plurality of users remembered for the IM client who is being treated as expired; and

automatically treating the particular user as no longer expired, responsive to the receiving.

11. The method according to claim 1, further comprising:

sending an outbound message from the IM client to a particular one of the plurality of users remembered for the IM client who is being treated as expired; and

automatically treating the particular user as no longer expired, responsive to the sending.

12. The method according to claim 1, further comprising using a distinct visual indicator for those users remembered for the IM client who are being treated as expired when presenting those users'"'"' names on a display to a user of the IM client.

13. The method according to claim 1, wherein the users remembered for the IM client are those users having entries in an address book used by the IM client.

14. A method of managing user information in an instant messaging (“

IM”

) system, comprising;

evaluating, for an IM client that is operably connected to the IM system, which of a plurality of users remembered for the IM client are to be treated as expired but not deleted from the plurality of remembered users;

performing an IM presence detection function of the IM system to determine current presence status on behalf of the IM client, further comprising;

omitting each of the remembered users that are to be treated as expired as a remembered user when the presence detection function determines the current presence status, but not deleting the each of the remembers users that are to be treated as expired from the plurality of remembered users; and

including all others of the plurality of users remembered for the IM client as remembered users when the presence detection function determines the current presence status; and

providing, for the IM client, a visual indication for each of the plurality of remembered users, where each one of the plurality of remembered users that are to be treated as expired but not deleted from the plurality of remembered users is visually indicated differently from the all other ones of the plurality of users remembered for the IM client.

15. The method according to claim 14, wherein the different visual representation comprises moving names of the remembered users who are to be treated as expired to a folder structure displayed in one portion of a graphical user interface of the IM client while displaying names of the all other ones of the plurality of users remembered for the IM client in a different portion of the graphical user interface.

16. A computer-implemented method of managing user information in an instant messaging (“

IM”

) system, comprising;

using a data structure to record IM activity on behalf of a particular user of the IM system, wherein;

the data structure comprises a plurality of entries, each of the entries corresponding to a selected one of a plurality of other IM users remembered, by the IM system, on behalf of an IM client of the particular user; and

each of the entries comprises;

an identifier of the selected one of the plurality of remembered IM users to which the entry corresponds;

a first date indicating when the particular user last sent an instant message to the selected one;

a first time period indicating a first inactivity period allowed before the particular one wants the selected one to be treated as expired, the first inactivity period corresponding to inactivity on outbound instant messages sent from the particular one to the selected one; and

a current expiration status of the selected one;

upon sending an instant message from the particular one to any of the plurality of remembered IM users, automatically updating the first date in the entry corresponding to that remembered IM user to a current date and setting the current expiration status in the entry to indicate that the corresponding one of the remembered IM users is not yet expired;

periodically evaluating the entries in the data structure to determine, for the IM client of the particular user, whether any of the plurality of remembered IM users should be treated as expired, further comprising, for each of the entries for which the current expiration status indicates that the corresponding one of the remembered IM users is not yet expired;

adding the first time period from the entry to the first date from the entry, thereby computing an outbound inactivity comparison date; and

setting the current expiration status in the entry to indicate that the corresponding one of the remembered IM users is to be treated as expired if the outbound inactivity comparison date is prior to the current date; and

performing a presence detection function of the IM system to determine current presence status on behalf of the IM client, comprising;

for each one of the plurality of remembered IM users for whom the current expiration status of the corresponding entry in the data structure indicates that that one of the remembered IM users is to be treated as expired, omitting this user as a remembered IM user when the presence detection function determines the current presence status, but not deleting this one of the remembered IM users from the plurality of IM users remembered for the IM client; and

including all others of the plurality of remembered IM users when the presence detection function determines the current presence status.

17. The computer-implemented method according to claim 16, wherein:

the first time period is selected by the particular user; and

the first time period is different among at least two of the entries.

18. The computer-implemented method according to claim 16, further comprising enabling the particular user to specify that one of the plurality of remembered IM users will be immediately treated as expired and in response, automatically setting the current expiration status in the entry corresponding to that one of the remembered IM users to indicate that the corresponding one is to be treated as expired.

IM”

) system, comprising;

using a data structure to record IM activity on behalf of a particular user of the IM system, wherein;

the data structure comprises a plurality of entries, each of the entries corresponding to a selected one of a plurality of other IM users remembered, by the IM system, on behalf of an IM client of the particular user; and
