ABSTRACT A signalling protocol 400 for use in communication between cellular telephone exchanges 10, 12, and 14. The signalling protocol 400 for messages is structured to include software package data 478, 572, 620, 670 which identifies the particular software package or version used by the message source. This enables the cellular telephone exchange 10, 12, or 14 which receives the signalling protocol 400 to understand the capabilities and features incorporated in the sending cellular telephone exchange 10, 12, or 14, by virtue of the version of the software package incorporated in the sending cellular telephone exchange 10, 12, or 14. Although the signalling protocol 400 is described as used by three cellular telephone exchanges, 10, 12, and 14, any number of like systems can use the signalling protocol 400.
