Abstract

A system and method of managing log information of a user, includes: a service server receiving a login/logout request from the user; the service server selecting a location server group to transmit a log message to, corresponding to the login/logout request, based on the user'"'"'s user identifier; transmitting the log message as an anycast message from the service server to a location server of the selected location server group; the location server, which receives the log message, generating a status update message corresponding to the log message; and the location server multicasting the generated status update message to remaining location servers of the selected location server group.

Claims

1. A computer implemented method of managing log information of a user, the method comprising:

receiving a login/logout request for a service server from a user;

selecting a location server group to transmit a log message thereto, corresponding to the received login/logout request, wherein the location server group includes a plurality of location servers;

transmitting the log message from the service server to a first location server included in the selected location server group, wherein the log message includes login/logout status of the user;

upon receipt of the log message, generating a status update message for the first location server to which the log message is transmitted, corresponding to the log message; and

transmitting the generated status update message to other location servers of the selected location server group.

2. The method of claim 1, further comprising:

updating first user log information stored in the first location server according to the generated status update message; and

updating second user log information stored in the other location servers of the selected location server group according to the received status update message.

3. The method of claim 1, further comprising:

determining whether the user'"'"'s status is a concurrent login status by referring to the updated first user log information; and

transmitting a force logout message to the service server which has transmitted the log message, when the user'"'"'s status is the concurrent login status.

4. The method of claim 1, wherein the location server group is selected based, at least in part, upon the user'"'"'s user identifier.

5. The method of claim 1, wherein the log message and the status update message comprise the user'"'"'s user identifier, the user'"'"'s login/logout status, and a location identifier associated with the user'"'"'s logged in/logged out location.

6. The method of claim 1, wherein the log message is transmitted from the service server to the first location server in anycast delivery scheme.

7. The method of claim 1, wherein the generated status update message is transmitted to the other location servers of the selected location server group in multicasting delivery scheme.

16. A computer-readable record medium storing a program for implementing the method according to claim 1.

8. A computer implemented method of managing log information of a user, the method comprising:

maintaining a plurality of location servers that manage users'"'"' log information, the plurality of location servers forming at least one group;

from a service server, wherein the log message includes a login/logout status of a user;

upon receipt of the log message, updating a first message buffer by referring to the received log message, generating a status update message associated with the updating, and transmitting the generated status update message to a second location server of the group; and

updating a second message buffer by referring to the received status update message.

9. The method of claim 8, further comprising:

any one of the first location server and the second location server determining whether the user'"'"'s status is a concurrent login status by referring to the updated first message buffer or the second message buffer, and when the user'"'"'s status is the concurrent login status, transmitting a forced logout message to the service server which has transmitted the log message.

10. The method of claim 8, further comprising:

maintaining a group identifier of each of the at least one group and user identifier information in a group information database, the user identifier information being assigned to the group identifier,

wherein the receiving of the log message comprises;

receiving the log message comprising the user'"'"'s log information, from the service server;

identifying a group identifier based on a user identifier included in the first message, and transmitting the log message to a location server corresponding to the identified group identifier; and

the location server receiving the log message.

11. A system for managing log information of a user, the system comprising:

a message receiving unit configured for receiving a login/logout request from a user;

a message generation unit configured for generating a log message corresponding to the login/logout request, wherein the log message includes login/logout status of the user;

a message allocation unit configured for selecting a location server group to transmit the log message thereto, wherein the location server group includes a plurality of location servers; and

a message transmission unit configured for transmitting the log message to a first location server of the selected location server group.

12. The system of claim 11, wherein the message receiving unit receives a forced logout message from the location server, the forced logout message comprising a second user identifier, and

the system further comprises:

a concurrent login processing unit configured for compulsorily terminating a connection of a user corresponding to the second user identifier comprised in the forced logout message.

13. A location server group comprising:

a plurality of location servers, each location server being communicatively coupled with the other location servers of the location server group via network, wherein each of the location servers comprises;

a message receiving unit configured for receiving a log message from a service server, wherein the log message includes a user identifier, login/logout status of the user, and a location information associated with the user'"'"'s login/logout location;

a message generation unit configured for generating a status update message corresponding to the log message; and

a message transmission unit configured for transmitting the generated status update message to the other location servers of the location server group in multicasting delivery scheme.

14. The location server group of claim 13, further comprising:

a user log processing unit configured for updating user log information stored in the location server according to the status update message which is generated in the location server, or according to the status update message which is received from the other location servers of the location server group.

15. The location server group of claim 13, further comprising:

a concurrent login processing unit configured for determining whether the user'"'"'s status is a concurrent login status by referring to the user log information, and transmitting a forced logout message to the service server which has transmitted the log message if the user'"'"'s status is the concurrent login status.
