Abstract

A presence management apparatus connected to first and second apparatuses via a network includes a unit for updating a first user'"'"'s presence received from the first apparatus and a second user'"'"'s presence received from the second apparatus, wherein the first user uses the first apparatus and the second user uses the second apparatus; a unit for registering a matching condition for another user'"'"'s presence received from the first apparatus and designated by the first user and a matching condition for another user'"'"'s presence received from the second apparatus and designated by the second user; and a unit for deciding if the first and second user'"'"'s presences match the designated conditions when registration processing and/or update processing is performed.

Claims

1. A presence management apparatus connected to a first apparatus and a second apparatus via a network, for managing presence representing a dynamic attribute of a user using said first apparatus or said second apparatus, the presence management apparatus comprising:

a user table for registering therein for each user a user ID, a presence of said user, and a matching condition for the presence which is designated by said user with respect to another user;

presence update means for updating a first user'"'"'s presence registered in said user table based on an update request received from the first apparatus, or updating second user'"'"'s presence registered in said user table based on an update request received from the second apparatus, wherein the first user uses the first apparatus and the second user uses the second apparatus;

matching condition registration means for registering at said user table, a matching condition for another user'"'"'s presence including the second user'"'"'s presence received from the first apparatus and designated by the first user and a matching condition for another user'"'"'s presence including the first user'"'"'s presence received from the second apparatus and designated by the second user; and

matching decision means of a bidirectional matching decision between the first and second users, for deciding if the updated first user'"'"'s presence matches the matching condition designated by the second user and the second user'"'"'s presence matches the registered matching condition designated by the first user, when the matching condition registration means performs matching condition registration processing for the matching condition designated by the first user or the matching condition designated by the second user, wherein

when said presence update means updated the first user'"'"'s presence or the second user'"'"'s presence registered in said user table based on an update request, in a case that said first user'"'"'s presence matches with the matching condition designated by the second user and also the second user'"'"'s presence matches with the matching condition designated by the first user, said matching decision means decides that both of the matching conditions relating to said first user'"'"'s and second user'"'"'s presences coincide with each other.

2. The presence management apparatus according to claim 1, comprising

matching notification means for, after updating process by said presence update means, notifying the first and/or the second apparatus that, when the matching decision means decided that said first user'"'"'s presence matches with the matching condition designated by the second user and also the second user'"'"'s presence matches with the matching condition designated by the first user, the matching has been satisfied.

3. The presence management apparatus according to claim 1,

wherein the matching condition registered by the matching condition registration means includes a combination of a logical sum and/or a logical product of a condition for two or more presences.

4. The presence management apparatus according to claim 1, comprising

a matching table for storing an identifier of the second user as one of matching candidates for an identifier of the first user when it is decided that the first user'"'"'s presence matches the matching condition designated by the second user and the second user'"'"'s presence does not match the matching condition designated by the first user.

5. The presence management apparatus according to claim 4,

wherein, when said matching decision means, in the decision process, searches said user table and decides that the updated second user'"'"'s presence matches the matching condition designated by the first user, said matching decision means searches said matching table to check whether the identifier of the second user has been stored in the matching table as one of matching candidates for the identifier of the first user.

6. The presence management apparatus according to claim 5,

wherein, said matching decision means checks said matching table, and when the identifier of the second user has been stored in the matching table as one of matching candidates for the identifier of the first user, the matching decision means decides that the both matching conditions are satisfied.

7. The presence management apparatus according to claim 4,

wherein, for the first user and the second user whose identifiers are stored as the matching candidates in said matching table, when the matching decision means decides that the first user'"'"'s presence which was updated does not match the matching condition designated by the second user, the matching decision means deletes the identifier of the first user and the identifier of the second user stored as the matching candidates for the identifier of the first user from the matching table.

14. The presence management apparatus according to claim 1, wherein a presence updated in response to the update request includes information about a location of an apparatus used by said user or a status of said user.

8. An information delivery system in which a first apparatus, a second apparatus, and a presence management apparatus are connected via a network, for managing presence representing dynamic attribute of a user using said first apparatus or said second apparatus,

wherein the presence management apparatus comprises:

a user table for registering therein for each user a user ID, a presence of said user, and a matching condition for the presence which is designated by said user with respect to another user;

presence update means for updating a first user'"'"'s presence registered in said user table based on an update request received from the first apparatus, or updating a second user'"'"'s presence registered in said user table based on an update request received from the second apparatus, wherein the first user uses the first apparatus and the second user uses the second apparatus;

matching condition registration means for registering at said user table, a matching condition for another user'"'"'s presence including the second user'"'"'s presence received from the first apparatus and designated by the first user and a matching condition for another user'"'"'s presence including the first user'"'"'s presence received from the second apparatus and designated by the second user; and

matching decision means of a bidirectional matching decision between the first and second users, for deciding if the updated first user'"'"'s presence matches the matching condition designated by the second user and the second user'"'"'s presence matches the registered matching condition designated by the first user, when the matching condition registration means performs matching condition registration processing for the matching condition designated by the first user or the matching condition designated by the second user, wherein

when said presence update means updated the first user'"'"'s presence or the second user'"'"'s presence registered in said user table based on an update request, in a case that said first user'"'"'s presence matches with the matching condition designated by the second user and also the second user'"'"'s presence matches with the matching condition designated by the first user, said matching decision means decides that both of the matching conditions relating to said first user'"'"'s and second user'"'"'s presences coincide with each other; and

matching notification means for, after updating process by said presence update means, notifying the first and/or the second apparatus that, when the matching decision means decided that said first user'"'"'s presence matches with the matching condition designated by the second user and also the second user'"'"'s presence matches with the matching condition designated by the first user, the matching has been satisfied,

wherein the first apparatus comprises means for delivering information to the second apparatus.

9. The information delivery system according to claim 8,

wherein the matching condition registered by the matching condition registration means of the presence management apparatus includes a combination of a logical sum and/or a logical product of a condition for two or more presences.

10. The information delivery system according to claim 8, comprising

a matching table for storing an identifier of the second user as one of matching candidates for an identifier of the first user when it is decided that the first user'"'"'s presence matches the matching condition designated by the second user and the second user'"'"'s presence does not match the matching condition designated by the first user.

11. The information delivery system according to claim 10,

wherein, when said matching decision means, in the decision process, searches said user table and decides that the updated second user'"'"'s presence matches the matching condition designated by the first user, said matching decision means searches said matching table to check whether the identifier of the second user has been stored in the matching table as one of matching candidates for the identifier of the first user.

12. The information delivery system according to claim 11, wherein, said matching decision means checks said matching table, and when the identifier of the second user has been stored in the matching table as one of matching candidates for the identifier of the first user, the matching decision means of the presence management apparatus decides that the both matching conditions are satisfied.

13. The information delivery system according to claim 10,

wherein, for the first user and the second user whose identifiers are stored as the matching candidates in said matching table, when the matching decision means of the presence management apparatus decides that the first user'"'"'s presence which was updated does not match the matching condition designated by the second user, the matching decision means deletes the identifier of the first user and the identifier of the second user stored as the matching candidates for the identifier of the first user from the matching table.

15. The information delivery system according to claim 8, wherein a presence updated in response to the update request includes information about a location of an apparatus used by said user or a status of said user.
