Patent ID: 8621107

Claim:
A data signaling method for message-based communication between a first communications unit and a second communications unit, said method comprising the steps of: initiating said message-based inter-unit communication by providing, in said first communications unit, a state comprising communications unit-associated data common to multiple communications messages to be transmitted between said first communications unit and said second communications unit; generating a copy of said state; transmitting said state copy and a first identifier of said state copy from said first communications unit to said second communications unit; generating a second identifier based on said received state copy; comparing said received first identifier and said generated second identifier; storing said state copy in said second communications unit; and processing, if said second identifier corresponds to said first identifier, a communications message of said multiple communications messages using said state or said state copy by modulating a size of said communications message based on at least a portion of said communications unit-associated data.
