    摘要: 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.

    摘要: In a cellular network, randomness is introduced into a transmitted signal at each transmitter, and the resulting received signal, which is the sum of all received signals, fluctuates more in time than a signal transmitted without the introduced randomness. While the introduction of randomness can diminish reception of some parts of the signal at the receiver, the transmitted signal can be encoded using forward error correction coding techniques, which allows the receiver to recover all of the signal information despite some diminished reception. Such randomization provides time diversity so that receivers can have more consistent performance. For broadcasted data, where users with the worst channel condition dictates the overall performance, having consistent performance across users can improve the overall network performance.

    摘要: A method includes establishing a secure connection between a client device and a first security gateway, the first security gateway being associated with a service provider for providing a service to the client device, and handing off the secure connection from the first security gateway to a second security gateway. Handing off the secure connection includes sending from the first security gateway to the second security gateway security information used to encrypt and decrypt messages transmitted through the secure connection, and sending from the first security gateway to the client device an address of the second security gateway to enable the client device to initiate contact with the second security gateway.

    摘要: 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.
