摘要： Apparatus and methods are disclosed for power optimization in a wireless device. The apparatus and methods effect monitoring the amount of data stored in a data buffer that buffers data input to and data output from a processor. Dependent on the amount of data stored in the buffers parameters of a control function, such as a Dynamic Clock and Voltage Scaling (DCVS) function are modified based on the amount of data stored in the data buffer. By modifying or pre-empting the parameters of the control function, which controls at least processor frequency, the processor can process applications more dynamically over default parameter settings, especially in situations where one or more real-time activities having strict time constraints for completion are being handled by the processor as evinced by increased buffer depth. As a result, power usage is further optimized as the control function is more responsive to processing conditions.

摘要： Techniques for managing resources on a wireless device are described. In an aspect, congestion of resources on the wireless device may be detected. If any resources are deemed to be congested, then congestion of the congested resources may be relieved by controlling utilization of the congested resources by at least one client. In one design, flow control may be performed for at least one data flow to relieve congestion of the congested resources. A pattern indicative of when to send messages enabling data transmission and when to send messages disabling data transmission may be selected. Messages may then be sent in accordance with the pattern to control transmission of data for the at least one data flow. Another pattern with a higher ON fraction or a lower ON fraction may be selected based on usage of the congested resources.

摘要： More seamless handoff between access networks is achieved by saving session information for each access network upon being handed off from the access network and invoking the saved session information upon being handed back to the access network. An access terminal establishes a first session with a first access network, which may entail performing QoS negotiation with the first access network and setting up packet filters at a packet data gateway. The access terminal exchanges data with the first access network in accordance with the configuration of the first session. The access terminal saves the first session configuration after being handed off to a second access network, establishes a second session with the second access network, and exchanges data with the second access network in accordance with the configuration of the second session. The access terminal uses the saved first session configuration upon being handed back to the first access network.
摘要翻译：通过在从接入网络切换时保存每个接入网络的会话信息并且在被递送到接入网络时调用保存的会话信息来实现接入网络之间的更无缝切换。接入终端与第一接入网建立第一会话，可能需要与第一接入网进行QoS协商，并在分组数据网关建立分组过滤。接入终端根据第一会话的配置与第一接入网络交换数据。接入终端在切换到第二接入网络之后保存第一会话配置，与第二接入网建立第二会话，并根据第二会话的配置与第二接入网交换数据。接入终端在被切回到第一接入网络时使用保存的第一会话配置。

摘要： A wireless communications device is configured to establish a radio level session with a network at a relatively high or highest protocol level among a plurality of protocol levels supported. Upon failures in establishing, or during, a network level data session, the radio level session is closed. Thereafter, the device re-attempts to establish the network level session at a lower, fallback protocol level, by pretending it is a legacy device incapable of supporting the high protocol level. In this manner, the network is likely to follow a different procedure in establishing data communications, whereby an error that caused the failure is less likely to be repeated. As examples, error conditions in eHRPD data sessions result in fallback to HRPD or 1xRTT data sessions. A network based alternative embodiment implements protocol fallback via appropriate fallback instructions to the wireless device.
摘要翻译：无线通信设备被配置为在所支持的多个协议级别中的相对较高或最高协议级别与网络建立无线电级会话。在建立或在网络级数据会话期间发生故障时，关闭无线电级别会话。此后，设备重新尝试以较低的回退协议级别建立网络级会话，假设它是不能支持高协议级别的传统设备。以这种方式，网络可能遵循建立数据通信的不同过程，由此导致故障的错误不太可能被重复。作为示例，eHRPD数据会话中的错误条件导致HRPD或1xRTT数据会话的回退。基于网络的替代实施例通过适当的回退指令实现到无线设备的协议回退。
