Abstract
Two intelligent nodes are provided with the capability of negotiating a protocol between them so that if the intelligent nodes operate at two different protocols then they can select a protocol appropriate for their communication. Furthermore, the intelligent nodes are provided with a locking shift capability so as to select between codesets that are available within a selected protocol.
Claims13
A method of changing a codeset within a communication protocol, comprising:
- transmitting a codeset designator, from a first node to a second node after a communication protocol and a first codeset have been established between the first node and the second node, wherein the codeset designator identifies one of a plurality of codesets available for use under the communication protocol;
- transmitting control information, from the first node to the second node, wherein the control information identifies whether the codeset identified by the transmitted codeset designator is to be used on a temporary basis;
- and
- transmitting data, from the first node to the second node, in accordance with the established communication protocol and the transmitted codeset designator.
A communication node including a database that stores a protocol identification parameter associated with communication between the communication node and another communication node, wherein the stored protocol identification parameter is updated whenever the communication node receives a protocol identification parameter from the another communication node.
A message transmission having a data structure including a message type identifier, a protocol identifier, and a service provider identifier.
