20100290389 | Multi-carrier System Selection - In general, a method performed on a personal base station includes transmitting a first pilot signal to a portable access terminal operating in an idle mode in a macrocell that uses a first carrier frequency. The first pilot signal is transmitted in the first carrier frequency to allow the portable access terminal to temporarily connect to the first pilot signal. A second pilot signal is transmitted in a second frequency that is different than the first frequency. The portable access terminal is dispelled from the first pilot signal, and the portable access terminal is allowed to connect to the second pilot signal. | 11-18-2010 |
20100157941 | ACCESS TERMINAL HAND-OFF METHODS IN WIRELESS NETWORKS - This description relates to access terminal hand-off methods in wireless networks. | 06-24-2010 |
20100075658 | ACCESS TERMINAL AUTHORIZATION AT PRIVATE ACCESS POINTS IN WIRELESS NETWORKS - This description relates to access terminal authorization methods in wireless networks. | 03-25-2010 |
20090186626 | Allocating Code Space to Base Stations - In addition to other aspects disclosed, a portable base station requests a mobile handset to measure signal strengths associated with a portion of a code space. The portable base station also sends a message that represents the signal strength measurements to a remotely located control station. | 07-23-2009 |
20090170475 | Secure Mobile Base Station Connections - In addition to other aspects disclosed, through a non-secure network, one or more bidirectional secure logical connections are established between a mobile base station and a secure network interface. | 07-02-2009 |
20090170440 | Interference Mitigation in Wireless Networks - 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. | 07-02-2009 |
20090116445 | ACTIVE HANDOFFS IN A NETWORK - Techniques for transferring a communication connection for a client device from a source network device to a target network device include receiving first and second sequence numbers and applying a first processing technique to data segments associated with sequence numbers that succeed the first and the second sequence numbers. | 05-07-2009 |
20090034440 | DISTRIBUTED NETWORK - Systems and methods for a distributed network are provided. In some embodiments, a method includes automatically transmitting a page message for a mobile station to access points in a paging group associated with a first access point, the page message having been received at the first access point, the first access point being associated with the most recent location update of the mobile station, and establishing a security agreement between the first access point and the other access points prior to receiving the page message. | 02-05-2009 |
