International Classification:

H04B 700

US Classification:

455446, 455449, 455422, 455 676

Abstract:

In a radio communications network ( ) having a plurality of cells ( ) employing a plurality of cell site configurations ( and ), a computing system ( ) and a computer-based method ( ) create a hierarchical data structure ( ) modeling the radio communications network ( ). The hierarchical data structure ( ) is created using object oriented programming methodology to create objects, representing the various physical components of a cell site. In addition, objects are created to represent the auxiliary information, such as available channels, channel assignment constraints, carrier-to-interference ratios, and neighbors lists under which a particular radio communications network configuration is devised.

International Classification:

G06K 1906

US Classification:

235492, 235376, 235487, 705 14, 705 16

Abstract:

A method and system for providing advertisement information, including advertising as well as sales promotions, on chip cards that additionally involves an electronic money rebate to the consumer, and for the distribution, accounting, and recovery of the associated electronic money rebates. Rebates are conveyed to the consumer by communication from the advertisement information provider to a customers chip card via a multiplicity of possible channels including: a personal computer, a portable chip card reader, a point-of-sale (POS) terminal, a handheld device, a home or business telephone, a vending machine, a cellular phone, a pager, a mass transporation payment station, a television and/or television set-top box, or an automated teller machine (ATM). Rather than giving a discount at the point of sale, a rebate in the form of electronic money is stored in chip card memory. The method and system also include tracking and storing integrated relational information regarding advertisement information, products, and customers buying habits with respect to those products for which rebates have been given.

International Classification:

A04Q 720

US Classification:

455450, 455452, 455 62

Abstract:

Channels are assigned ( ) to a subject cellular network ( ) after taking into account the locked/unlocked status of cells ( ). Channels are assigned to locked cells ( ) in accordance with a prearranged assignment plan ( ). After this assignment, one unlocked cell ( ) is selected ( ) at a time. An available channels list is built ( ) for the selected unlocked cell ( ), and a channel is selected ( ) from this list for assignment to the selected unlocked cell ( ). The available channels list is built ( ) by evaluating all channels in the network ( ) one at a time to determine if their assignment to the selected unlocked cell ( ) would cause undue interference in any other cell ( ) of the network ( ). If interference worse than a minimum system threshold is detected ( ) in another cell ( ), a channel is made unavailable for assignment unless it is a locked cell ( ). For a locked cell it is made unavailable ( ) if the channel assignment would worsen interference by more than an offset value.

International Classification:

US Classification:

455456, 455 676, 455506, 455 65

Abstract:

A method, executed on a simulation system ( ), characterizes propagation of a radiofrequency signal ( ) in a three-dimensional environment ( ). The method includes forming a database ( ) of propagation paths ( ) of the radiofrequency signal ( ) transmitted from a transmitter ( ) at a fixed location ( ) in the three-dimensional environment ( ). The propagation paths ( ) are represented by a plurality of line segments ( ) in the database ( ). Local line segments ( ) are selected from the plurality of line segments ( ) to establish a subset ( ) of the propagation paths ( ). The subset ( ) includes those propagation paths ( ) each having one of the local line segments ( ) proximate a location ( ) of a receiver ( ) in the environment ( ). Distinct multipath components ( ) representing distinct wavefronts of the radiofrequency signal ( ) are subsequently identified from the subset ( ) of the propagation paths ( ).

International Classification:

H04Q 700

US Classification:

370329, 370341

Abstract:

In a cellular communication network ( ) having a channel assignment plan ( ) that distinguishes frequency channels ( ) assigned to a plurality of cells ( ), a method ( ) and system ( ) adapt the channel assignment plan ( ) during network planning to include shared frequency channels ( ). Borrower cells ( ) are identified in response to a deficiency value ( ) indicating a shortage in a quantity of the frequency channels ( ) assigned to the borrower cells ( ). Donor cells ( ) are selected from the cells ( ) in response to a load factor ( ) for each of the cells ( ), the load factor ( ) indicating the number of frequency channels ( ) already being shared by the cell ( ). Candidate frequency channels ( ) that may be shared are evaluated against predetermined channel sharing constraints, such as frequency separation constraints ( ), co-channel carrier-to-interference C/I constraints ( , and adjacent channel C/I) constraints ( ).
