Abstract
The method and apparatus for completing calls to mobile stations in a mobile radio communications network provides efficient routing of calls, reduced utilization of system resources, and consistent services to a mobile station wherever located. The invention includes a national home location register (HLR) with a wireless enhanced services platform (WESP) with integrated voice mail/audio response capability. Calls to and from mobile subscribers are delivered to the WESP. The WESP interacts with the national HLR to provide consistent mobile services as well as enhanced services such as information collection and validation prior to call completion. When a call to a mobile station is placed, the call is directed to the WESP which transmits the identity of the mobile station to the national HLR. The national HLR looks up the mobile station and obtains the identity of the serving mobile switching center/visitor location register (MSC/VLR) where the mobile station is actually located and a list of the features in effect for the mobile station. The list of features in effect is transmitted to the WESP which performs the functions necessary to implement the features. These functions incl…
