International Classification:

H04Q 720

US Classification:

455435, 455410

Abstract:

The present method and system for transmitting feature and authentication information for wireless communication services reduces the amount of data transmitted from a handset to a base station by transmitting service information when the wireless handset registers with the base station and authentication information when wireless service is requested by the wireless handset. After receiving the service and authentication information, the base station may store the service and authentication information in memory and retrieve the stored service and authentication information when the wireless handset again requests service from the base station. Alternatively, a mobile switching system may communicate the service and authentication information to the base station.
