Abstract:
A cable communication system (100) where a control unit (110) sends operation parameters to subscriber units (130) and the subscriber units (130) respond by modifying the method of communication. Also, the subscriber units (130) send messages which include information on the subscriber unit (130) and the capabilities of the subscriber unit (130). Furthermore, the control unit (110) efficiently manages the system (100) by monitoring the capabilities and instructing the subscriber units (130) on how to communicate on the system (100). Such management allows for the migration of subscriber units (170) from one service area (140) to another (190) without the disruption of service. In addition, initialization of subscriber units (130) may be accomplished over the cable and does not require an operator at the subscriber location.
Abstract:
A method of routing control information and bearer traffic in a packet network. When a wireless communication device (108) has established a connection in a coverage area serviced by an Access Network Controller (ANC) (106) and a Serving Node (104) and roams into an area serviced by a new ANC (112) and a new Serving Node (110), the present invention routes control information to and from the device through the anchor Serving Node (Serving Node through which the connection was established). Bearer traffic is routed to and from the device GGSNor wireless communication device through the ANC and Serving Node serving the area in which the wireless communication device is located.

Abstract:
A method for assigning communication resources includes assigning communication resources (216, 218, 220) in the nature of bandwidth according to various selection schemes based upon the type of communication service being provided, and based upon the nature of the service area (128, 130) and subscriber premises (132, 134).
Abstract:
A method for detecting fraudulent use of a communication system (10) includes the steps of determining a system parameter associated with a subscriber unit (32). The system then compares the system parameter to a previous system parameter for the subscriber unit (32). An alarm is set when the system parameter differs more than a predetermined amount from the previous system parameter.
Abstract:
A method of updating a software code in a cable communication system (10) involves the steps of receiving a notification (100) by a cable access unit (30). Next, the cable access unit (30) receives (110) the software code. After receiving (110) the software code the CAU (30) resets (114) and reboots using the software code.
