  • Patent number: 7349704
    Abstract: A method and system for sharing over-allocated bandwidth between different classes of service in a wireless network. Traffic is transmitted for a first service class in excess of bandwidth allocated to the first service class using unused bandwidth allocated to a second class. After transmitting traffic for the first service class in excess of bandwidth allocated to the first service class using unused bandwidth allocated to a second class, traffic for a third service class is transmitted in unused bandwidth remaining in the second service class.

  • Patent number: 7346354
    Abstract: A method and system for dynamic soft handoff resource allocation in a wireless communications network includes determining a wireless path characteristic individually for each path of a macro diversity connection between a mobile device and a plurality of wireless sites. Wireless resources are allocated for the macro diversity connection between the mobile device and the wireless sites based on the wireless path characteristic. The wireless path characteristic includes a location-based characteristic, a congestion-based characteristic, a subscriber-based characteristic and/or a performance-based characteristic.

  • Patent number: 7225238
    Abstract: A method and system for providing services for wireless data calls includes monitoring a wireless data call for a predefined event associated with a service for the wireless data call. The service is initiated for the wireless data call in response to detecting the predefined event for the data call. The predefined event may comprise a uniform resource locator (URL) match or change, excess use of transmission or time resources, a location change of a mobile device for the wireless data call, a network event, or a combination of any or all suitable events.

  • Patent number: 7126913
    Abstract: A method and system for managing transmission resources in a wireless communications network includes receiving a plurality of packets and determining a time duration for transmission of each packet. A power level for transmission of each packet over the time duration is further determined. Based on the time duration and the power level determined for each packet, a wireless resource impact is determined for each packet. Transmission resources are allocated to each packet based on the wireless resource impact determined for each packet.

  • Patent number: 7068624
    Abstract: A wireless communications network includes a wireless-specific router topology layer that connects cellular sites to a wireline topology. The wireless-specific router topology provides a distributed architecture in which call processing including call setup, resource preservation, air bandwidth allocation, switching, soft handoff, and micromobility is performed at the cell level. The wireless routers are technology independent to support various cellular technologies. The wireless router may include a first interface operable to communicate wireless packets for a call with a remote device and a second interface operable to communicate wireline packets for the call with the wireline network. A traffic controller is coupled to the first and second interfaces and operable to convert traffic between the wireless and wireline packets and to route packets to a destination mobile or wireline device.

  • Patent number: 7043225
    Abstract: A method and system for brokering bandwidth in a wireless communications network includes receiving a request for a wireless service at a geographic region. An availability of the wireless service is determined at the geographic region. A response to the request is generated based on the availability of the wireless service. The response includes one or more terms for the wireless service.
