Application provider and method for communication

Abstract

In one aspect of the present invention, an application provider, such as a mobile application part provider (52), is provided that includes a table (210), a router (200) and a message converter (220). The table (210) stores information corresponding to a sub-system, such as a visitor location register (46) or a home location register (44), of a first node, such as an integrated wireless telecommunications switch (14). The router (200) analyzes an application part message, such as a mobile application part message, that originated from the first node and compares the information stored in the table to the destination of the application part message to determine if the application part message is destined for the sub-system of the first node. The router (200) communicates the application part message to the first node if the application part message is destined for the sub-system of the first node. The message converter (220) converts the application part message to a transaction capability application part message if the router (200) determines that the application part message is not destined for the sub-system of the first node.
