Abstract
The invention is directed to a instant messaging method and communication system comprising one or more network elements, wherein a connection from one to another network element can be established using a protocol which allows the sending of one or more messages from the one to the another network element as part of one or more protocol words. The protocol includes a protocol portion allowing a network element to specify whether or not the message is to be stored in case it cannot be promptly delivered to the another network element. The protocol portion preferably is part of the protocol header. The protocol may be a Session Initiation Protocol (SIP), and the message can be contained in an Invite request sent from the sending equipment to the receiving equipment.
