Abstract
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.
Claims24
A method performed on a personal base station, the method comprising:
- 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 being transmitted in the first carrier frequency to allow the portable access terminal to temporarily connect to the first pilot signal;
- concurrently transmitting, with the first pilot signal, a second pilot signal in a second frequency that is different than the first frequency;
- intermittently alternating the first pilot signal between a first state and a second state;
- dispelling the portable access terminal from the first pilot signal during the first state;
- and
- allowing the portable access terminal to connect to the second pilot signal during the first state.
A method performed on a personal base station, the method comprising:
- 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 being transmitted in the first carrier frequency to allow the portable access terminal to temporarily connect to the first pilot signal;
- concurrently transmitting, with the first pilot signal, a second pilot signal in a second frequency that is different than the first frequency;
- transmitting information that forces the portable access terminal to measure inter-frequency cells;
- and
- allowing the portable access terminal to connect to a second pilot signal.
A personal base station comprising:
- a transmitter to:
- transmit 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 being transmitted in the first carrier frequency;
- concurrently transmit, with the first pilot signal, a second pilot signal in a second carrier frequency;
- and
- intermittently alternating the first pilot signal between a first state and a second state;
- circuitry to allow the portable access terminal to temporarily connect to the first pilot signal;
- circuitry to dispel the portable access terminal from the first pilot signal during the first state;
- and
- circuitry to allow the portable access terminal to connect to the second pilot signal during the first state.
A personal base station comprising:
- a transmitter to:
- transmit a first pilot signal to a portable access terminal operating in an idle mode in a macrocell that uses a first carrier frequency, the pilot signal being transmitted in the first carrier frequency;
- concurrently transmit, with the first pilot signal, a second pilot signal in a second carrier frequency;
- and
- transmit information that forces the portable access terminal to measure inter-frequency cells;
- circuitry to allow the portable access terminal to temporarily connect to the first pilot signal;
- and
- circuitry to allow the portable access terminal to connect to the second pilot signal.
