Abstract:
A method for establishing a communication protocol between a first network node and a second network node wherein the second network node is capable of operating at any one of a plurality of communication protocols, the method comprising the steps of:receiving, at the second network node, an indication of the operating communication protocol of the first network node;based on said indication, selecting as a designated protocol a communication protocol from the plurality of communication protocols, wherein said plurality of communication protocols includes at least two protocols related to each other in that one of said protocols is of a later version than the other protocol;storing an identification of the selected communication protocol in association with said first network node and when subsequently initiating communication from said second network node to said first network node referring to the stored identification to select a communication protocol; andsending an indication of said designated protocol to the first network node,wherein after the second network node sends an indication of said designated protocol to the first network node said second network node performing the steps of:selecting a messaging codeset from a plurality of messaging codeset within said designated protocol; andindicating the selected messaging codeset to the first network node.
