摘要： The disclosure is directed to managing registration of a wireless communication device (WCD) operating in a wireless network. The WCD may support registration according to a signaling protocol, such as session initiation protocol (SIP). The WCD adjusts a registration timer based on network quality experienced by the WCD. When network quality is poor, for example, the WCD reduces the length of the registration timer. Reduced network quality may indicate that the WCD is at risk of losing network coverage. By reducing the length of the registration timer when network quality is degraded, stale registrations for out-of-coverage WCDs can be reduced. In particular, the shortened registration timer will expire more quickly, permitting the registration to be cleared more quickly. Consequently, the amount of call forwarding and other resources devoted to stale registrations can be reduced. If the WCD retains network coverage, it can maintain a registration by sending another registration request.
摘要翻译：本公开涉及管理在无线网络中操作的无线通信设备（WCD）的注册。 WCD可以根据诸如会话发起协议（SIP）的信令协议来支持注册。 WCD根据WCD所经历的网络质量调整注册计时器。当网络质量差时，例如，WCD减小了注册定时器的长度。降低网络质量可能表明WCD有可能丢失网络覆盖。通过减少网络质量降低时的注册定时器的长度，可以减少覆盖范围外的WCD的过时的注册。特别地，缩短的注册定时器将更快地过期，从而允许更快地清除注册。因此，可以减少用于过期注册的呼叫转移和其他资源的数量。如果WCD保留网络覆盖，则可以通过发送另一个注册请求来维护注册。

摘要： In the various aspects, virtualization techniques may be used to improve performance and reduce the amount of power consumed by translating virtual memory addresses into physical addresses on a computing system having hybrid memory. In a first stage of memory translation, an operating system translates virtual addresses to intermediate physical addresses. In a second stage of memory translation, a chip or virtualization software translates the intermediate physical address to physical addresses based on the characteristics of the physical memory and the characteristics of the processes associated with the physical memory.

摘要： A Base Station Controller (BSC) that reduces the occurrence of audible noise in a Code Division Multiple Access (CDMA) radio network is provided. The BSC according to one embodiment of the present invention comprises a Media Stream Board (MSB) for compressing groups of 160 PCM speech samples from a Public Switch Telephone Network (PSTN) into vocoded frames, and a Special Purpose Board (SPB) for reformatting the vocoded frames from the MSB into over-the-air CDMA vocoded frames. The MSB and SPB each have a local timer that is slave to “PSTN time”. The BSC further comprises a Timing Unit Board (TUB) connected to a GPS receiver. The TUB receives “GPS time” from the GPS receiver. The TUB generates timing cells, each containing time-of-day information according to “GPS time”. The TUB distributes the timing cells to the MSB and the SPB over an Asynchronous Transfer Mode (ATM) network. The MSB and SPB use the received timing cells to compare their local timer, which tracks “PSTN time”, to “GPS time”. The MSB and the SPB realign their local timer with “GPS time” whenever their local timer drifts from “GPS time” outside of a predetermined time window.
