Abstract

A method of routing a call directed to a portable directory number in a radio telecommunications network having an originating mobile switching center (O-MSC) (11), a home location register (HLR) (12), and a Number Portability Database (NPDB) (13). The O-MSC determines whether to send a Location Request (LOCREQ) message (14) to the HLR for a routing number, or to send a Number Portability Request (NPREQ) (16) message to the NPDB for a location routing number (LRN). The determination may be based on operator preference, a default preference, or statistics indicating that either the HLR or the NPDB is more likely to return a routing number. The O-MSC then attempts to obtain a routing number from the determined destination. If an error message (15) is returned, the O-MSC attempts to obtain a routing number from the alternate destination. Upon receipt of a routing number, the O-MSC routes the call. In an alternative embodiment, the O-MSC may send the LOCREQ message and the NPREQ message simultaneously, and utilize the first routing number received to route the call.
