    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： 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.

    摘要： The present invention provides a method and an apparatus of wireless communication with at least one wireless unit The method includes detecting an indication of error in a plurality of traffic frames to control transmit power between at least a first and second forward link based on the indication of error. The method further includes receiving a plurality of consecutive traffic frames over at least two reverse links from a wireless unit to select a frame in soft handoff. To control transmit power, for example, a controller may perform reverse link error detection after frame selection. The controller detects a frame error to boost the transmit power, substantially correcting a link imbalance situation. In this way, by controlling transmit power in a spread spectrum wireless communication system to reduce call drops, a call drop rate may be significantly decreased while increasing capacity of radio frequency transmission.
