    • A method of selecting a type of resource-allocation to use for a call in a cellular wireless system, such as selecting a type of radio configuration to use for the call. According to the method, resource-availability in one more adjacent coverage areas may be used as a basis to select the type of resource-allocation to use in a current coverage area. For instance, given the choice between a radio configuration that consumes less base station power and a radio configuration that consumes more base station power, the radio configuration consuming more base station power may be selected if base station sufficient power is available in one or more adjacent coverage area(s), and the other radio configuration may be selected if insufficient base station power is available in the one or more adjacent coverage area(s). Distance between the mobile station and a current base station may be considered as well.

    • A method and system is disclosed for interlaced control channel. When a RAN in a wireless communication system operating at least according to IS-856 determines that a delay condition exists in the transmission of control packets to access terminals, it invokes interlacing of time slots bearing control-channel data. By so doing, control packets are transmitted in interlaced fashion, thereby reducing delay in transmission compared with sequential transmission of control packets. A delay condition could correspond to a measured delay exceeding a threshold delay, a predicted delay (e.g., based on queue occupancy) exceeding a threshold number, or the number of access terminals eligible to receive control messages during a particular time interval exceeding a different threshold number. The RAN may monitor transmission delay of control packets on a per-control-channel-cycle basis, and apply interlaced transmission of control packet only during those control-channel cycles for which a delay condition has been determined to exist.
    • 公开了用于隔行控制信道的方法和系统。 当至少根据IS-856操作的无线通信系统中的RAN确定在向接入终端发送控制分组时存在延迟条件时,它调用带有控制信道数据的时隙的交织。 通过这样做,以隔行方式发送控制分组,从而相比于控制分组的顺序发送减少传输延迟。 延迟条件可以对应于超过阈值延迟的测量延迟,超过阈值的预测延迟(例如,基于队列占用),或者在特定时间间隔期间有资格接收控制消息的接入终端的数量超过不同的阈值 数。 RAN可以在每个控制信道周期的基础上监视控制分组的传输延迟,并且仅在已经确定了延迟条件的控制信道周期中应用控制分组的隔行传输。

    • A method and system is disclosed for intelligent power control in a wireless communication system. In accordance with an example embodiment, a first device will operate in a dynamic-power state in which it responds to each power-increment command and power-decrement command received from a second device by incrementing or decrementing transmission power on an air interface. While operating in the dynamic-power state, the first device will recognize when a first threshold number of alternating power-increment and power-decrement commands have been received, and responsively will transition to operating in a steady-power state in which it no longer increments or decrements transmission power in response to power-control commands from the second device. While operating in the steady-power state, the first device will recognize when receives a particular sequence of power-control commands from the first device, and based at least on the recognition will transition to operating in the dynamic power state.

    • Methods and an apparatus are provided for providing handoff information to a candidate mobile node initially served on a first carrier. The candidate mobile node may inform a wireless-communication network that hard-handoff criteria are met for the first carrier. The network may identify a plurality of neighboring mobile nodes served on a second carrier and within a threshold distance of the candidate. The network may receive a measurement of forward-link signal quality of the second carrier from each neighboring mobile node. Using the received forward-link-signal-quality measurements, the network may estimate the forward-link signal quality of the second carrier at the location of the candidate mobile node. If that estimated forward-link signal quality exceeds a signal-quality threshold, the network may provide hard-handoff information about the second carrier to the candidate mobile node.

    • Air interface protocols under the numerous wireless communication standards allow use of a quick-paging channel (QPCH) to expedite paging and call setup. When a hybrid mobile device is engaged in wireless communications under a first air interface protocol, it may periodically switch over to a second air interface protocol to check for pages on the slower standard paging channel (PCH). To increase throughput under the first air interface protocol, it would be useful to employ the QPCH under the second air interface protocol, to reduce time spent by hybrid device checking for pages under the second air interface protocol. However, the QPCH uses resources under the second air interface protocol, so it would be best to not have the QPCH activated at all times. According to the invention, the system would activate the QPCH under the second air interface protocol in response to there being more than an upper threshold number of hybrid devices active under the first air interface protocol. In turn, the system may deactivate the QPCH under the second air interface protocol in response to there being some lower threshold number of hybrid devices active under the first air interface protocol.
    • 许多无线通信标准下的空中接口协议允许使用快速寻呼信道(QPCH)来加速寻呼和呼叫建立。 当混合移动设备在第一空中接口协议下进行无线通信时,它可以周期地切换到第二空中接口协议以检查较慢的标准寻呼信道(PCH)上的页面。 为了增加第一空中接口协议下的吞吐量,在第二空中接口协议下采用QPCH将有助于减少混合设备检查第二空中接口协议下的页面所花费的时间。 然而,QPCH使用第二空中接口协议下的资源,因此最好不要始终激活QPCH。 根据本发明,系统将在第二空中接口协议下激活QPCH,以响应在第一空中接口协议下存在多于高阈值数量的混合设备。 反过来,系统可以在第二空中接口协议下响应于在第一空中接口协议下有一些较低阈值数量的混合设备有效而在第二空中接口协议下去激活QPCH。
