Abstract: A method and system for busy presence state detection in an instant messenger system. The method may include detecting a computer system activity level, determining whether the activity level exceeds an activity threshold, and transitioning a presence state of an instant messenger to a busy state in response to determining that the activity level exceeds the activity threshold, where the presence state corresponds to a given user. The system may include a computer system and an instant messenger software module configured to execute on the computer system. The instant messenger software module may be further configured to detect a computer system activity level, determine whether the activity level exceeds an activity threshold, and transition a presence state of the instant messenger software module to a busy state in response to the determination that the activity level exceeds the activity threshold, where the presence state corresponds to a given user.

Abstract: A method and system for processing instant messenger operations dependent upon presence state information in an instant messaging system. In one embodiment, the method may include receiving an instant messaging operation directed to a given user, where the given user is not offline; determining a presence state of an instant messenger in response to receiving the instant messaging operation, where the presence state corresponds to the given user; and selectively processing the instant messaging operation dependent upon the presence state in response to the determination. In another embodiment, the method may include storing an instant messaging operation associated with a given presence state of an instant messenger, where the given presence state corresponds to a given user; detecting a transition to the given presence state subsequent to storing the operation; and performing the instant messaging operation in response to the detection.

Abstract: A method and system for presence state assignment based on schedule information in an instant messenger system. In one embodiment, the method may include storing schedule information corresponding to a given user, where the schedule information is indicative of an activity status of the given user at a given time. The method may further include querying the schedule information, and if a current presence state of an instant messenger does not correspond to the activity status indicated by the schedule information, assigning a different presence state that corresponds to the activity status in response to the querying, where the current presence state and the different presence state each correspond to the given user.
