  • Patent number: 7983672
    Abstract: Communication is initiated with a radio access network through a first private access point according to a first air interface standard based on a first identifier corresponding to the first private access point. A second identifier corresponding to the first private access point is determined by using a roaming list. The second identifier is associated with the first identifier in the roaming list. A set of one or more carrier frequencies for communication according to a second air interface standard is determined using the roaming list. The second identifier is mapped to the set of one or more carrier frequencies in the roaming list. Based on the roaming list, initiation of communication with the radio access network is attempted through the first private access point according to the second air interface standard based on the second identifier at one carrier frequency of the set of one or more carrier frequencies.

  • Publication number: 20110130116
    Abstract: A wireless access point is capable of communicating with an access terminal. The wireless access point executes instructions for receiving a first parameter from the access terminal in an attempt by the access terminal to register with the wireless access point for first service, for using the first parameter to update a failed list if the access terminal is not permitted to register with the wireless access point, for receiving a second parameter from the access terminal in an attempt by the access terminal to register with the wireless access point for second service, and for using the second parameter and the failed list to determine if the access terminal is authorized to use the wireless access point for second service.

  • Publication number: 20110081864
    Abstract: Among other things, a method performed by a first access point is described. The method includes outputting signals. At least some of the signals interfere with communication between a device and a second access point. The method also includes determining whether to output the signals in a predefined mode based on dynamically calculated values of a parameter. The parameter is related to signal interference at the device. If it is determined to output the signals in the predefined mode, for a time period, the first access point outputs signals in the predefined mode.

  • Patent number: 7835698
    Abstract: A method of mitigating interference between a private access point and an access terminal in a radio access network, where the private access point uses a shared carrier frequency that is shared with a macro access point, and where the access terminal has an idle operational state and an active operational state, includes directing the access terminal to move to a first carrier frequency other than the shared carrier frequency if the access terminal operates on the shared carrier frequency in the active operational state. The access terminal is configured to communicate with the macro access point and the access terminal is not authorized to communicate with the private access point. N carrier frequencies are used by the macro access point, where N?2.

  • Patent number: 7801487
    Abstract: A device causes at least one access terminal that is configured to transmit data to a radio node in a sector of a radio access network to alter transmission. While transmission is altered, the device determines a power of a signal received at the radio node, and updates an average value of signal power using the power measured. A device receives, from one or more access terminals that are configured to receive data from a radio node in a sector of a radio access network, a requested rate at which information should be transmitted to each access terminal, receives from the access terminals information about quality of signals received from the radio node, and generates an event if the requested rate and the information about quality of signals fail to satisfy a condition. An access terminal, located in the vicinity of a first radio node configured to transmit data in a sector of a radio access network, measures signal power of pilot signals received by the access terminal.

  • Publication number: 20100085910
    Abstract: A system is used in a wireless communication system made up of cells, at least one of which includes at least one sector. The system includes first access points in a first area of a sector of a cell. The first access points are prohibited from communicating over a first frequency. The system also includes second access points in a second area of the sector of the cell. The second access points are prohibited from communicating over a second frequency that is different from the first frequency.
