摘要:
There is provided a method and apparatus for reducing packet assistant channel power usage in a wireless telephone system. More specifically, there is provided a method comprising measuring a power usage for a packet assistant channel, determining whether the power usage is above a threshold, and discontinuing transmission over the packet assistant channel for a period of time if the power usage is above the threshold.

The present invention provides a method of wireless telecommunication. The method includes accessing information indicative of a first mobile unit in response to a signal from the first mobile unit, accessing information indicative of at least one second mobile unit, and comparing the information indicative of the first and second mobile units. The method also includes establishing a call connection with the first mobile unit based on the comparison of the information indicative of the first and second mobile units.

A method for determining rise over thermal for a base station in a wireless communications system is provided. The method comprises receiving a first and second diversity signal, measuring the signal strength of the first and second diversity signals, and estimating the noise floor for the first and second diversity signals. The signal strength rise is determined for the first and second diversity signals based on the measured signal strength and estimated noise floor of the first and second diversity signals respectively. The rise over thermal is then determined based on the determined signal strength rise of the first and second diversity signals.

A method is provided for controlling a traffic-to-pilot ratio (TPR) in a wireless telecommunications channel. The methodology takes advantage of a preexisting feedback process used in hybrid ARQ transmission systems. Generally, information is transmitted over the communications channel, and then the acknowledgement (ACK) signal, or negative acknowledgements (NACK) signal, is used to adjust the TPR. The TPR is adjusted up substantially in response to receiving a NACK signal, and adjusted slightly down in response to receiving an ACK signal. In this manner, the TPR is rapidly adjusted up when a transmission fails, and is allowed to drift slowly down when a transmission succeeds.

The present invention provides a method is provided for blocking alert messages to mobile units. The method includes determining at least one location of at least one mobile unit based on at least one response to a first page message provided to the at least one mobile unit. The method also includes interrupting transmissions to the at least one mobile unit based on said at least one determined location of said at least one mobile unit.

The present invention provides a method and an apparatus for communication with at least one wireless unit over a forward and a reverse link in a wireless network. The method includes receiving a feedback indication on at least a first channel over the forward link for reception of a transmission on at least a second channel over the reverse link, and adjusting transmit power of a wireless unit associated with the network based on the feedback indication. For example, a transmitter at a wireless unit associated with a spread spectrum wireless network, such as a code division multiple access cellular network, may control transmit power of in a reverse link. Specifically, the feedback indication for reception of a traffic or control channel over the reverse link may be received on a channel that is available on the forward link for another purpose than providing power control feedback. In this way, the transmitter performs reverse link power control at the wireless unit. By performing such reverse link power control, the transmitter obviates many conventional drawbacks associated with a receiver-centric power control in a feedback-based spread spectrum wireless communications system.
摘要:
A method is provided for controlling communications between a base station and a mobile device. The method comprises enlarging a search window in which a transmission is expected to be received in response to the absence of an external timing signal, such as when the global positioning system (GPS) is shut down. Additionally or alternatively, the method further comprises altering the timing of a received signal relative to a search window, such as by delaying the timing of the received signal to move the signal toward the center of the search window.

The present invention relates to a system and method for load sharing among multiple base stations using Network Initiated Handover (NIHO). In one embodiment, the method includes computing scores for qualified pairs of candidate mobile station and target base station for potential network initiated handover (NIHO), and selecting a pair of candidate mobile station and target base station based on the computed scores to handover the candidate mobile station of the selected pair from the serving base station to the target base station of the selected pair.
摘要:
A method of receiving data packets. In the method of receiving data packets, a determination is made as to whether a received data packet is received out of an expected order. If the determining step determines a received packet is out of the expected order, a time period is calculated to wait for one or more missing data packets based at least in part on an expected time of receiving the one or more missing data packets.
