ABSTRACT:
An auto-provisioning routing node including a mobile services node network address translation database and an auto-provisioning function for automatically provisioning the database is disclosed. The auto-provisioning routing node receives signaling messages that require network address translation services. The auto-provisioning routing node routes messages for which no translations exist to a default mobile services node and adds entries for the corresponding IMSIs in its mobile services node network address translation database. The default mobile services node determines whether it has records for these messages. If the default mobile services node does not have records for these messages, the default mobile services node routes the messages to a second mobile services node via the routing node. The routing node updates entries for IMSIs in the mobile services node network address translation database based on the information inserted by the default mobile services node. This process may continue by mobile services nodes routing to subsequent nodes, with the routing node continuing to update its database, until the mobile services node containing the IMSI is found.
