Patent number: 7983672Abstract: 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.Type: GrantFiled: December 19, 2007Date of Patent: July 19, 2011Assignee: Airvana, Corp.Inventors: Pierre A.

Patent number: 7801487Abstract: 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.Type: GrantFiled: December 29, 2005Date of Patent: September 21, 2010Assignee: Airvana, Inc.Inventors: Sepehr Mehrabanzad, Satish Ananthaiyer, Pierre A.
