International Classification:

G06F 15173

US Classification:

395500

Abstract:

An arrangement (apparatus and method) for dynamically provisioning infrastructure components in a digital communication network using an object-oriented relational paradigm. A network configuration system, also referred to as a video support system, stores all related information on each of the infrastructure components (IFCs) as objects in an object oriented relational database, including the functions, capabilities, locations, when and how the IFCs are assigned, and the capacities, working and spare, existing in and between various locations. The objects are arranged into clusters based on common characteristics, and the object clusters (modules), selectively access other modules to provide functional and logical connections independent from nonrelevant objects, such as physical location. Entity relationships establish the relevancy of different objects and object clusters. The object-oriented relational paradigm allows new technology devices to be added to the infrastructure, and enables intelligent infrastructure components to perform dynamic and adaptive configurations with minimal modification in the provisioning system.

Abstract:

A method and system is disclosed for triggering handoff of a call from a CDMA network to an AMPS network on which it is overlaid responsive to a determination that the CDMA RF link has degraded to such an extent that the call quality will be degraded significantly or the call is likely to be dropped is disclosed. A handoff of a call from a CDMA network to an AMPS network if, at a given time: (1) the number of forward link erasures is greater than a first maximum number of forward link erasures; or (2) the number of reverse link erasures is greater than a first maximum number of forward link erasures; or (3) the number of forward link erasures is greater than a second maximum number of forward link erasures and the forward traffic channel gain is greater than a maximum forward traffic channel gain; or (4) the number of reverse link erasures is greater than a second maximum number of reverse link erasures and the ratio of energy per bit to noise power spectral density on the reverse link ("EB/NO") is greater than a maximum EB/NO. In alternative embodiments, the present invention may be used to trigger handoff of a call from a first CDMA cell site to a second CDMA cell site or to an AMPS cell site serving a cell on which the cell served by the first CDMA cell site is not overlaid.

Abstract:

Improved savory snack food items include a nonsweet, sugar-based binder composition which adheres one or more toppings to a base portion of the snack. The binder does not undesirably alter the taste of snack food items and substantially reduces separation of toppings from the snack food items during production, packaging, shipping and, most importantly, during handling by the consumer. The binder also reduces transfer of oil and fat and powders to the hands of the consumer.
