| 20090238135 | SYSTEM AND METHOD FOR PROVIDING VOICE OVER INTERNET PROTOCOL QUALITY OF SERVICE SUPPORT IN A WIRELESS COMMUNICATION NETWORK - A system for providing Quality of Service (QoS) for voice over internet protocol (VoIP) provides a remote station with the address of an SIP proxy server. The initiates a VoIP service flow by sending an Invite to the proxy server via a bay station. If the service flow is authorized, the remote station transmits a request to the base station to establish a service flow having a selected QoS. The proxy server also provides a dynamic address for a voice gateway. Once the service flow is established, the remote station transmits RTP packets to the designated voice gateway using the service flow having the designated QoS level. | 09-24-2009 |
| 20090042537 | SUBSCRIBER MANAGEMENT SYSTEM FOR A COMMUNICATION NETWORK - A subscriber management system for a communication system having a radio access network coupled to by a gateway node to a packet switched network. The system consolidates three prior art subscriber management system components, a DPI device, a QoS Policy Manager | 02-12-2009 |
| 20080318585 | SYSTEM AND METHOD FOR CELL PLANNING IN A WIRELESS COMMUNICATION NETWORK - A cellular network having a plurality of mobile stations and a plurality of cells. Each cell is configured to provide communication services to the plurality of mobile stations using at least two overlapping channels. Each cell includes a base station configured to provide communication services using at least four channels, which include the overlapping channels, within a service area divided into three or four sectors. The service area may be hexagonal or square shaped. A first pair of the four channels has an overlapping portion. A second pair of the four channels, the channels of the second pair being different channels than those of the first pair, may also have an overlapping portion. The four channels may each comprise a portion of an Educational Broadband Service/Broadcast Radio Services band. The first and second pairs of channels may be nonadjacent to one another. | 12-25-2008 |
| 20080240032 | SYSTEM AND METHOD FOR CONDENSED FREQUENCY REUSE IN A WIRELESS COMMUNICATION SYSTEM - A legacy spectrum allocation results in inefficient use of the spectrum now allocated to broadband services. A broadband wireless OFDMA communication system allocates channels with overlap between adjacent channels to make more efficient use of the allocated spectrum. Guard tones are eliminated to reduce channel bandwidth requirements leaving a smaller bandwidth overlap. Interference mitigation procedures are used to reduce adjacent channel interference. | 10-02-2008 |
