摘要： A wireless communication network includes base stations that operate with variable transmit power adjustments during soft handoff of a mobile station. Base stations adjust current transmit powers up or down using variable step sizes responsive to power control commands from the mobile station. Step size depends on the difference between current transmit power and a common reference power. Generally, power control commands that move transmit power away from the common reference power are attenuated by decreasing the step size, and those that move the transmit power toward the reference power are amplified by increasing step size. A base station controller adjusts the common reference power during soft handoff to reduce differences between it and the current transmit powers. Thus, step size may be large at the outset of soft handoff to quickly reduce transmit power imbalance between base stations, but tends to decrease with subsequent adjustments of the common reference power.

摘要： Certain aspects of the present disclosure relate to a technique for touch temperature management of a wireless communications device based on power dissipated over time, and possibly internal temperature readings. For example, the information about power dissipated over time can be utilized along with monitored internal temperatures of a device's internal circuitry to reduce transmit power and/or data rates as required in order to keep a surface temperature of the wireless device below a specified limit. A knowledge of how the device's touch temperature varies with the dissipated power and a knowledge of the power dissipation history can be utilized to determine when to reduce the transmit power in order to avoid overheating (e.g., exceeding the touch temperature limit).

摘要： An operational mode of a terminal is dynamically configured to allow the terminal to receive services of interest to the terminal while potentially conserving battery power. The terminal operates in a first mode (e.g., an HRPD-only mode) and monitors only a first radio network (e.g., an HRPD network) for pages from a first data network (e.g., and IMS network) if all services from a second data network (e.g., an ANSI-41 network) of interest to the terminal is obtainable via the first radio network. The terminal operates in a second mode (e.g., an 1X-HRPD mode) and monitors the first radio network and a second radio network (e.g., a 1X network) for pages from the first and second data networks, respectively, if at least one service from the second data network of interest to the terminal is not obtainable via the first radio network. The terminal may dynamically select the first or second mode.

摘要： A mobile communication device with multiple subscriptions includes a single baseband-radio frequency (BB-RF) resource chain. A first identity module, such as a subscriber identity module (SIM), a second identity module (e.g., a second SIM), and a controller are communicatively coupled to the single BB-RF resource chain. The first identity module is associated with a first subscription, and the second identity module is associated with a second subscription. The controller may be configured to arbitrate access to the single BB-RF resource chain to perform a first activity that corresponds to the first subscription or a second activity that corresponds to the second subscription. For example, the controller may interrupt a data session processed by the single BB-RF resource chain in response to receiving information indicating that a voice call is to be processed by the single BB-RF resource chain.

摘要： Systems and methodologies are described herein that facilitate data session suspend control in a multi-radio wireless communication system based on user equipment capability. As described herein, various techniques are provided herein whereby a wireless communication network with which a user device communicates can suspend a data session and/or other communication session associated with the user device upon identifying that the user device has moved to a disparate communication network based on the transmitter/receiver capabilities of the user device. In one example herein, a mobility management entity and/or other network management entity can determine whether to perform suspend control based on an event notification from another network based on user capability. In another example herein, a network to which a user device moves can determine whether to send an event notification to another network associated with the user device based on capabilities of the user device.

摘要： A wireless communication network manages variable data rate communication channels using both short-term data rate adaptation and longer-term resource allocation adjustment. For example, an exemplary base station system may track the actual transmit power being used to transmit a given communication channel on a per frame basis, or faster, and use that tracked value to infer changing channel conditions, e.g., for a given current data rate, higher power indicates poorer channel conditions and lower power indicates better channel conditions. Additionally, or alternatively, channel quality information reported by a receiving mobile station can be used. Regardless, relatively fast data rate changes can be made responsive to monitoring the channel conditions, while retaining the communication resource allocation for the channel. Over the longer term, however, the allocation itself can be changed, e.g., increased or decreased, depending on whether the channel is being efficiently utilized.
摘要翻译：无线通信网络使用短期数据速率适配和长期资源分配调整来管理可变数据速率通信信道。例如，示例性基站系统可以跟踪用于以每帧为基础或更快地发送给定通信信道的实际发射功率，并且使用该跟踪值来推断出改变的信道条件，例如对于给定的当前数据速率，较高的功率表示较差的信道条件，较低功率表示较好的信道条件。另外或者可以使用由接收移动台报告的信道质量信息。无论如何，可以在保持通道的通信资源分配的同时对监视信道状况做出相对较快的数据速率变化。然而，从长远来看，分配本身可以根据信道是否被有效地利用而改变，例如增加或减少。

摘要： In a wireless communication network providing voice and data services, one or more entities in the network, such as a base station controller and/or radio base station, can be configured to reduce data services overhead responsive to detecting a congestion condition, thereby increasing the availability of one or more network resources for voice services. In one or more exemplary embodiments, one or more current data services users are targeted for modification of their ongoing data services to effect the reduction in data services overhead. Modifications can include, but are not limited to, any one or more of the following: forward or reverse link data rate reductions, and shifting of forward or reverse link traffic from dedicated user channels to shared user channels. Targeting of users for service modification can be based on reported channel quality information. For example, users reporting poor radio conditions can be targeted first for service modifications.
