METHOD AND APPARATUS FOR IMPROVED CALL CONNECTIVITY IN AN INTELLIGENT WIRELESS NETWORK

摘要

The method and apparatus for completing calls to mobile stations in a mobile radio communications includes a national home location register (HLR) (183) 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 identiy of the serving mobile switching center/visitor location register (MSC/VLR) where the mobile station is already located and a list of 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.
