摘要:
The present invention provides a method of handing off a mobile unit that supports multiple quality-of-service (QoS) application layer clients that operate according to multiple wireless access technologies in a packet-switched communication system. The method includes receiving information indicating a request to hand off the mobile unit from a first access network that operates according to a first wireless access technology to a second access network that operates according to a second wireless access technology. The mobile unit established a first session according to the first wireless access technology at a first QoS level. The method also includes establishing, concurrently with the first session and in response to receiving the handoff request, a second session according to the second wireless access technology at the first QoS level. The method further includes communicating with the mobile unit at the first QoS level using the first and second sessions.

In one embodiment of the method, a base station is configured to divide a coverage area of the base station into sub-coverage areas. Each sub-coverage area has a smaller range of round trip propagation delays than a range of round trip propagation delays for the coverage area of the base station. Each sub-coverage area may have a different range of round trip propagation delays.

摘要:
A method for controlling access of a subscriber station to a wireless communications system facilitates the maintenance of a performance target of the reverse link and desired geographic coverage of the reverse link. The method for controlling access of a subscriber station to a wireless communications system includes measuring a first performance indicator and a second performance indicator for a reverse link associated with a subscriber station seeking access to a wireless communications system. A blocking threshold value is established based upon the measured second performance indicator and may be adjusted to allow more or less blocking based on any additional metrics that characterize the performance of the current subscriber stations. The decision to grant or deny access of the subscriber station to the wireless communications system is determined based on a comparison of the measured first performance indicator to the established blocking threshold value.
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.
摘要:
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.
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.
