Abstract
A system and method for providing network and port address translation is provided. A global IP address and a block (chunk) of ports are allocated for each mobile subscriber (MS) on first data connection. Subsequent data connections from the same MS are assigned the same IP address and a new port from this block. The mapping information is communicated, processed, and stored once for the complete block, instead of for every new data connection. This process reduces processing, communication, and storage requirements.
