Methods for restricting access of network devices to subscription services in a data-over-cable system
First Claim
1. In a data-over-cable system including a plurality of network devices, a method of restricting access for a network device, comprising the following steps:
- receiving a connection request from a first network device on a second network device on the data-over cable system for a subscription service on the data-over-cable system;
determining from the second network device, whether information about the first network device is available on the data-over-cable system, and if not, assigning a temporary restricted network address for a restricted connection to the first network device on the data-over-cable system from pre-determined list of restricted network addresses, wherein the temporary network address from the pre-determined list of restricted network addresses provides restricted access to subscription services on the data-over-cable system;
starting a connection timer on the data-over-cable system for a restricted connection to the first network device, wherein the connection timer restricts access to subscription services on the data-over-cable system over a timed interval; and
creating a restricted connection between the data-over-cable system and the first network device including the temporary restricted network address and the connection timer, thereby providing restricted access to subscription services the data-over-cable system.

Abstract
Methods for providing restricted access for a network device such as a cable modem or customer premise equipment on a data-over-cable system. An unknown or new network device is assigned a restricted network address such as a restricted Internet Protocol address. The restricted network address allows the network device to access less than all of the available features on the data-over-cable system. A connection timer is started on the data-over-cable system for a restricted connection to the network device. The connection timer restricts access to the data-over-cable system over a timed interval. A restricted connection is created between the data-over-cable system and the network device including the temporary restricted network address and the connection timer, thereby providing restricted access to the data-over-cable system over a timed interval. The methods may allow a data-over-cable system to provide restricted connections to unknown or new network devices without a long delay, yet provide security to the data-over-cable system.

starting a connection timer on the data-over-cable system for a restricted connection to the first network device, wherein the connection timer restricts access to subscription services on the data-over-cable system over a timed interval; and
creating a restricted connection between the data-over-cable system and the first network device including the temporary restricted network address and the connection timer, thereby providing restricted access to subscription services the data-over-cable system. - View Dependent Claims (2, 3, 4, 5, 6, 7, 8, 9, 10, 11)
determining from the second network device, whether information about the first network device is available on the data-over-cable system, and if so, assigning an unrestricted network address for an unrestricted connection to the first network device on the data-over-cable system from a list of unrestricted network addresses; and
creating an unrestricted connection to a subscription service between the data-over-cable system and the first network device including the unrestricted network address, thereby providing unrestricted access to a subscription service on the data-over-cable system.

12. In a data-over-cable system including a plurality of network devices, a method of changing access for a network device, comprising the following steps:
-
creating a restricted connection between a first network device and the data-over-cable system including a restricted network address from a pre-determined list of restricted network addresses providing restricted access to a subscription service the data-over-cable system, and a connection timer restricting access to the subscription service on data-over-cable system over a timed interval, thereby providing restricted access to the subscription service to the data-over-cable system over a timed interval;
obtaining information from the first network device on a second network device to uniquely identify the first network device on the data-over-cable system;
saving the information in a database associated with the second network device; and
changing the restricted connection to the subscription service between the first network device and the data-over-cable system to an unrestricted connection to the subscription service between the first network device and the data-over-cable system by;
terminating the restricted connection to the subscription service between the first network device and the data-over-cable system from the second network device;
receiving a new connection request from the first network device on the second network device to the subscription service on the data-over cable system;
validating information about the first network device using information from the database associated with the second network device; and
creating an unrestricted connection for the subscription service between the first network device and the data-over-cable system using information from the database. - View Dependent Claims (13, 14, 15, 16, 17)

18. In a data-over-cable system including a plurality of network devices, a method of restricting access for a network device, comprising the following steps:
-
receiving a connection request from a cable modem on a cable modem termination system on the data-over cable system for a subscription service on the data-over-cable system;
determining from the cable modem termination system, whether information about the cable modem is available on the data-over-cable system, and if not, assigning a temporary restricted Internet Protocol address for a connection to the cable modem on the data-over-cable system from pre-determined list of restricted Internet Protocol addresses, wherein the temporary Internet Protocol address from the pre-determined list of restricted Internet Protocol addresses provides restricted access to the subscription service on the data-over-cable system;
starting a connection timer on the data-over-cable system for a restricted connection to the subscription service for the cable modem, wherein the connection timer restricts access to the subscription service on the data-over-cable system over a timed interval; and
creating a restricted connection between the data-over-cable system and the cable modem including the temporary restricted Internet Protocol address and the connection timer, thereby providing restricted access to the subscription service on the data-over-cable system over a timed interval. - View Dependent Claims (19)
