  • Patent number: 6563919
    Abstract: A gateway cluster has a number of gateways for different types of communication protocols. The respective gateways convert network messages to normalized messages by querying the categories, data, and network types of the normalized data for the mobile systems from which the network messages were generated. A database system stores normalized data in categories. The normalized data include data relating to the mobile systems and network types for the data. A unified mobility manager is coupled to and in communications with the gateway cluster and the database system. The unified mobility manager receives and processes the normalized messages, performs operations based on the normalized messages and on the categories, the data, and the network types of the normalized data, and formulates normalized responses responsive to the normalized messages. The normalized responses are converted to network responses at the gateways, and the network responses are sent to the respective mobile systems.

  • Patent number: 6295291
    Abstract: A potential radiotelephone service subscriber logs on to a world wide web server (105) using an internet access device (101). The potential subscriber is presented with a plurality of selectable radiotelephone services and features. The potential subscriber then provides the billing system (130) with credit information that is validated through the credit validation system (140). A radiotelephone service profile is stored in the home location register (110) after the subscription process has been completed. The subscriber is then instructed to power up the radiotelephone that then registers with the system. An over-the-air activation function (135) collects data from the billing system (130) and an authentication center (125) and sends the data to the mobile switching center (115) that then transmits it through the base station (120) to the radiotelephone. The radiotelephone reprograms its own registers with the appropriate data.
