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 for maintaining an always-on data session for an access terminal are described. Messages to keep alive the data session may be sent using non-traffic channels to avoid bringing up traffic channels just to send these messages. In one design, an access network may send a first message (e.g., a RouteUpdateRequest message) on a first non-traffic channel (e.g., a control channel) to the access terminal. The access terminal may return a second message (e.g., a RouteUpdate message) on a second non-traffic channel (e.g., an access channel) to the access network. The access network may then send a third message (e.g., for an Echo-Request) on the first non-traffic channel over a smaller area covering an approximate location of the access terminal, which may be determined based on the second message. The access terminal may return a fourth message (e.g., for an Echo-Reply) on the second non-traffic channel to the 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： 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： Methods, devices and computer program products are disclosed that allow for wireless communication devices to operate more robustly in the slotted mode of operation in the event of network system loss. Specifically, present aspects require the wireless device to move to or remain in the slotted mode of operation as opposed to immediately entering into a system determination/acquisition mode upon failing to acquire an active set pilot during a slotted wake-up (420, NO). By moving to the slotted mode of operation or providing for additional slotted wake-ups (450), a number of attempts at acquiring the active set pilot can be performed before declaring the system as lost (470), thereby allowing for fading channel conditions to prevail without the need to re-acquire the lost system or otherwise acquire another system. Since the performance of the slotted mode is less power intensive than acquiring or re-acquiring a system, a substantial power savings is realized.
摘要翻译：公开了方法，设备和计算机程序产品，其允许无线通信设备在网络系统丢失的情况下以更长时间的操作模式更鲁棒地操作。具体而言，本方面要求无线设备移动到或保持在时隙操作模式，而不是在时隙唤醒（420，否）期间无法获取主动集合导频时立即进入系统确定/获取模式，。通过移动到时隙操作模式或提供额外的时隙唤醒（450），可以在宣告系统丢失之前执行获取主动集导频的尝试次数（470），从而允许衰落信道条件不需要重新获取丢失的系统或以其他方式获取另一个系统。由于开槽模式的性能比获取或重新获取系统的功耗更小，所以实现了大量的功率节省。

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： A broadband service is provided by allocating air interface resources in a wireless network that conforms to the 1xEV-DO standard. The air interface resources are characterized by various quality of service (QoS) parameters, such as bandwidth, packet priority and error rate. Packetized information is transmitted in data flows between a base station and cell phones. A particular QoS level is reserved for each of the data flows that support the broadband service. An operating system on a cell phone monitors one data flow as well as another data flow in the opposite direction. When the base station runs out of an air interface resource, the base station suspends the QoS reservation of a data flow. The operating system determines that the QoS reservation in one direction has been suspended and sends an unsolicited message to the base station releasing the QoS reservation in the opposite direction, thereby conserving network resources. forward data flow

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.
