System and method of wireless instant messaging
First Claim
1. A method of operating a server comprising:
- receiving a single instant message from a first messaging client addressed to a group, the single instant message having presence information indicating a presence state of the first messaging client;
responsive to receiving the presence information, determining that the first messaging client is in a communicative state;
determining that the first messaging client is in an unknown state if a predetermined time period passes after the receipt of the presence information from the first messaging client without receiving additional presence information from the first messaging client;
resolving the group to two or more user ids (identifications), the two or more user ids (identifications) identifying second messaging clients that are in a communicative state;
sending a message and a notification of a presence state of the first messaging client to each of the two or more user ids (identifications) when the first messaging client is in the communicative state; and
refraining from transmitting the notification when the first messaging client is in the unknown state.

Abstract
Instant messaging clients transmit, to a server, presence information indicating that the respective client is in a communicative state in which the client is receptive to communicating with the other clients. A server determines, for each client, that the respective client is in a communicative state if presence information was received from the client over a preceding predetermined time period, and that the client is in an unknown state if presence information was not received from the client over the preceding predetermined time period. The communicative state and the unknown state are possible presence states of the clients. The server transmits a notification to a second client of the presence state of a first client when both the first client and the second client are in a communicative state. But the server refrains from transmitting the notification to the second client when the first client is in the unknown state.

9. A mobile communication device comprising:
-
a communication subsystem configured to send, to a server, a single instant message having presence information indicating a presence state of the subsystem addressed to a group, the group being associated with two or more user ids; the server being configured to determine that the subsystem is in a communicative state responsive to the receipt of the presence information, and to determine the subsystem is in an unknown state if a predetermined time period passes after the receipt of the presence information without receiving additional presence information from the subsystem; the server being further configured to resolve the group to the two or more user ids, the two or more user ids identifying messaging clients that are in a communicative state and then send a message and a notification of a presence state of the subsystem to each of the two or more user ids when the subsystem is in the communicative state and refrain from sending the notification when the subsystem is in the unknown state. - View Dependent Claims (10, 11, 12)

13. A wireless instant messaging system comprising:
-
a wireless messaging server configured to receive a single instant message from a first messaging client addressed to a group, the instant message having presence information indicating a presence state of the first messaging client; the server being further configured to determine that the first messaging client is in a communicative state responsive to the receipt of the presence information, and to determine that the first messaging client is in an unknown state if a predetermined time period passes after the receipt of the presence information without receiving additional presence information from the first messaging client; the server being further configured to resolve the group to two or more user ids, the two or more user ids identifying second messaging clients that are in a communicative state, and to send a message and a notification of a presence state of the first messaging client to each of the two or more user ids when the first messaging client is in the communicative state and to refrain from sending the notification when the first messaging client is in the unknown state. - View Dependent Claims (14, 15, 16, 17, 18, 19, 20)
