Abstract
A wireless telephone and messaging system provides Secure Immediate Wireless Access (SIWA) to wireless telephones onto existing wireless networks, such as GSM, CDMA, TDMA, and analog (AMPS). The SIWA protocol uses existing wireless network messaging to exchange information between wireless devices and a network server, referred to herein as an Intelligent Service Manager (ISM). The ISM acts as a gateway between wireless devices and wireless service provider, and provides the wireless devices with an immediate limited or unlimited access to the wireless network. The ISM can also deny access to the wireless network from unauthorized wireless devices.
