ABSTRACT:
A communication method allows members of an affinity group to obtain up-to-date information concerning the status of other members of the affinity group. Each member of the affinity group is provided with a communication device for communicating with other members. The communication device includes a memory for storing member status information. When the status of one member in the affinity group changes, a status update message is sent from the member whose status has changed to other members of the affinity group. When a status update message is receiving from other members, the status information data contained in the message is used to update the member status information stored in memory.
