Abstract: In order to improve the quality of a telephone call communicated over a wireless local area network (WLAN), an electronic device (such as a cellular telephone) may obtain one or more performance metrics based on communication with another electronic device (such as an access point) via a connection in the WLAN. For example, the electronic device may receive the one or more performance metrics from the other electronic device and/or may determine the one or more performance metrics based on the performance of the communication. Then, the electronic device may compare the one or more performance metrics with an interference criterion. If the interference criterion is met, the electronic device may perform a remedial action, such as selectively discontinuing use of the WLAN to communicate the telephone call for a time interval. Otherwise, the electronic device may continue using the WLAN to communicate the telephone call.

Abstract: A multi-mode communication device having a scan optimizer capable of prioritizing scan frequencies for different radio access technologies (RATs) during a network search. The scan frequency prioritization may be based on various network coverage considerations associated with RAT availability, RAT density within a region, geographic location, historic attachment for the multi-mode device, an operation mode of the multi-mode device, etc. The multimode device can utilize its scan optimizer to generate an optimized scan schedule to be employed for a limited duration during a network search to improve its likelihood of success in detecting and/or attaching to a network associated with a prioritized RAT. A default scan schedule having equal scan frequency prioritization can be employed by the multi-mode device at a time when the limited duration of the optimized scan schedule expires and no networks associated with a prioritized RAT have been acquired.
Abstract translation: 一种具有扫描优化器的多模式通信设备，其能够在网络搜索期间优先考虑不同无线电接入技术（RAT）的扫描频率。 扫描频率优先级可以基于与RAT可用性，区域内的RAT密度，地理位置，多模式设备的历史连接，多模式设备的操作模式等相关联的各种网络覆盖考虑。多模设备 可以利用其扫描优化器来产生在网络搜索期间在有限持续时间内使用的优化扫描调度，以提高其在检测和/或附着到与优先化RAT相关联的网络的成功的可能性。 在优化的扫描计划的有限持续时间到期并且没有获得与优先化的RAT相关联的网络的时候，多模式设备可以采用具有相同扫描频率优先级的默认扫描调度。

Abstract: Methods and apparatus to mitigate interference among multiple wireless subsystems of a wireless communication device are described. A host processor obtains configurations for a plurality of wireless subsystems and evaluates whether potential or actual coexistence interference exists between two or more of the wireless subsystems. The host processor provides configuration information and link quality reporting parameters to and obtains link quality reports from at least two wireless subsystems. When link quality for at least one wireless subsystem fails a set of link quality conditions, the host processor adjusts data requirements for applications that communicate through one or more of the wireless subsystems and/or adjusts radio frequency operating conditions for one or more of the wireless subsystems to mitigate interference among the wireless subsystems.

Abstract: In video conferencing over a radio network, the radio equipment is a major power consumer especially in cellular networks such as LTE. In order to reduce the radio power consumption in video conferencing, it is important to introduce an enough radio inactive time. Several types of data buffering and bundling can be employed within a reasonable range of latency that doesn't significantly disrupt the real-time nature of video conferencing. In addition, the data transmission can be synchronized to the data reception in a controlled manner, which can result in an even longer radio inactive time and thus take advantage of radio power saving modes such as LTE C-DRX.

Abstract: A method and apparatus for forced cell/RAT reselection is disclosed. In one embodiment, a cellular mobile communication device may attempt to access a network through a serving cell. Responsive to determining that access to the network is barred through the serving cell, the mobile communication device may determine if another cell is available through which it may obtain access to the network. If another cell providing network access is available, the mobile communication device may force reselection from the serving cell to the new cell. If no other cell providing access to the network is available to the mobile communication device, a forced reselection of a radio access technology may be performed.
