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： 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： The disclosure relates to techniques for maintaining minimum quality of service (QoS) communication sessions with a wireless communication device (WCD) over a data-based communication network during a hard handoff between access networks for the WCD. More specifically, the techniques determine whether a closed connection between the WCD and a first access network during a minimum QoS communication session is due to a hard handoff between the first access network and a second access network. In the case of a hard handoff, the techniques maintain open QoS reservations associated with data flows included in the minimum QoS communication session for a predetermined period of time to enable a new connection to be established between the WCD and a second access network. The techniques described herein may especially useful when performing a voice over Internet Protocol (VoIP) call over an Evolution - Data Optimized (EVDO) communication network.

摘要： Techniques to detect for end of service using dynamic inactivity timer thresholds are described. An access terminal establishes a radio connection for one or more applications. Data and signaling for the application(s) may be sent on one or more first flows (e.g., RLP flows) that may carry any number of second flows (e.g., IP flows). The access terminal determines a dynamic inactivity timer threshold for each first flow, e.g., based on at least one inactivity timer threshold for at least one second flow mapped to that first flow. The access terminal determines whether each first flow is inactive based on the inactivity timer threshold for that first flow, e.g., declares each first flow to be inactive if no activity is detected on that first flow for a period exceeding the inactivity timer threshold. The access terminal closes the radio connection when all first flow(s) are determined to be inactive.
摘要翻译：描述使用动态不活动定时器阈值检测服务结束的技术。接入终端为一个或多个应用建立无线电连接。用于应用的数据和信令可以在可携带任何数量的第二流（例如，IP流）的一个或多个第一流（例如，RLP流）上发送。接入终端例如基于映射到该第一流的至少一个第二流的至少一个不活动定时器阈值来确定每个第一流的动态不活动定时器阈值。接入终端基于该第一流的不活动定时器阈值来确定每个第一流是否不活动，例如，如果在超过非活动定时器阈值的时间段内在该第一流上没有检测到活动，则将每个第一流声明为不活动。当所有第一流被确定为不活动时，接入终端关闭无线电连接。

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： 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。

摘要： Techniques for routing data via lower layer paths through lower layers of a protocol stack are described. A lower layer path may be composed of a flow for packets, a link at a link layer, and a channel at a physical layer. A packet may be received from an application. A most preferred lower layer path for the packet may be selected from among at least one available lower layer path. The available lower layer path(s) may be arranged in an order of preference based on treatment of packets (e.g., best effort or QoS), protocols used at the link layer, channel types at the physical layer, and/or other factors. The packet may be sent via the selected lower layer path. A highest precedence lower layer path for the packet may be set up (e.g., in parallel) if this path is not among the at least one available lower layer path.
