Abstract
Given access to two or more originating switching node addressing mechanisms (such as, for example, a mobile switching center identification (MSCID), a mobile switching center identification number (MSCIN) and/or a point code subsystem number (PC-SSN)), a serving switching node, when needing to address a message to that originating switching node, implements a hierarchical process for selecting one of the two or more available mechanisms for use in addressing the message. The process gives preference to use of the MSCIN, if present and if the message is being sent in an international routing context, in addressing the message. Alternatively, the process gives preference to use of the PC-SSN, if present and if the message is being sent in a national routing context, in addressing the message. Lastly, the process utilizes the MSCID in addressing the message.
