apparatus and method of management status information in wireless instant messaging system

摘要

In a wireless instant messaging system, a first mobile station transmits a PUBLISH message including status information and watcher information. A second mobile station reads the status information published or updated by the first mobile station. A presence server publishes or updates status information mapped to the watcher information included in the PUBLISH message received from the first mobile station and transmits a notification message including the status information to the second mobile station mapped to the watcher information. Other parties (watchers or groups) can read status information desired by a subscriber when the subscriber sets status information for the other parties to read discriminately according to need.
