摘要： A system and method to measure channel quality in terms of signal to noise ratio for the transmission of coded signals over fading channels. A Viterbi decoder metric for the Maximum Likelihood path is used as a channel quality measure. This Euclidean distance metric is filtered in order to smooth out short term variations. The filtered or averaged metric is a reliable channel quality measure which remains consistent across different coded modulation schemes and at different mobile speeds. The filtered metric is mapped to the signal to noise ratio per symbol using a threshold based scheme. Use of this implicit signal to noise ratio estimate is used for the mobile assisted handoff and data rate adaptation in the transmitter.

摘要： A network infrastructure device of an apparatus in one example comprises a first external interface and a second external interface. The network infrastructure device communicates with a first telecommunication network through the first external interface. The network infrastructure device communicates with a second telecommunication network through the second external interface. The network infrastructure device allows a mobile communication device that has a first registration in the first telecommunication network and a second registration in the second telecommunication network to receive, through the second telecommunication network, a call directed to the first registration. The first telecommunication network is unable to directly query the second telecommunication network for a status of the second registration.

摘要： Systems and methods for performing a cellular call handover from a home node b (HNB) to a macro cellular communication node (e.g., a base station or radio access network) are disclosed. An interworking function (IWF) is provided in the HNB and acts as an anchor mobile switching center (MSC) for a user device served by the HNB, and communicates with a visited MSC for the HNB. The IWF sends a request to a target MSC (which may be the visited MSC) serving the HNB, to handover the call to the macro node. The call is then handed over to the macro communication node by the target MSC. In this manner, the IWF facilitates providing the described handover in conformity with existing 3GPP standards, without requiring additional standards to be generated and without requiring additional system components.

摘要： A control for an electrical generating and distribution system utilizing a plurality of interconnected microprocessors. An electrical system, for an aircraft for example, may have two engine driven generators and an auxiliary power unit generator with loads connected to each of the engine driven generators through generator circuit breakers. An electrical distribution bus connected through bus tie breakers interconnects the load circuits and the auxiliary generator so that any one generator can power either or both loads. Each generator has a microprocessor generator control unit responsive to the associated generator conditions to control generator operation. A microprocessor bus power control unit is responsive to distribution circuit conditions and correlates information from the generator control units, contributing to operation of the bus tie breakers, controlling distribution of power from the generators to the loads. Serial data links between the bus power control unit and each of the generator control units provide for communication of input and control information and enable comparison of redundant circuit information enhancing reliability of the system operation. A generator voltage regulator utilizes the microprocessor of the generator control unit to develop an error voltage which is added to the average phase voltage of the generator, controlling the generator field current. In the event of a phase failure the generator control unit senses an abnormally high phase voltage condition, disables the average phase voltage circuit and the regulator continues to operate with the error voltage.
摘要翻译：一种利用多个互连的微处理器的发电和配电系统的控制。例如，用于飞行器的电气系统可以具有两个发动机驱动的发电机和辅助动力单元发电机，其负载通过发电机断路器连接到每个发动机驱动的发电机。通过总线连接断路器连接的配电总线将负载电路和辅助发电机相互连接，以便任何一个发电机可以为任一负载电流或两个负载供电。每个发电机具有微处理器发生器控制单元，其响应相关联的发电机状况来控制发电机运行。微处理器总线功率控制单元响应于分配电路条件并将来自发电机控制单元的信息相关联，有助于总线断路器的操作，控制从发电机到负载的功率分配。总线功率控制单元和每个发电机控制单元之间的串行数据链路提供输入和控制信息的通信，并且能够比较提高系统操作的可靠性的冗余电路信息。发电机电压调节器利用发电机控制单元的微处理器产生一个误差电压，该误差电压加到发电机的平均相电压上，控制发电机励磁电流。在相位故障的情况下，发电机控制单元检测到异常高的相电压状态，禁止平均相电压电路，并且调节器继续以误差电压工作。

摘要： A call processing method and system in which the use of the MGW between the RNC and the peer party is limited to only certain situations. This invention uses RFC 3267 (AMR/IETF) on the RNC. This will avoid inserting a MGW context for framing conversion only. This invention provides an optimization that sets up calls from the RNC, thus avoiding the need for a MGW in the path for basic calls. With this optimization, the usage of DSP and packet resources and the number of MGW chassis, as well as bearer path delay, are all reduced.

摘要： A method and system for providing circuit-switched to IP Multimedia Subsystem voice call continuity with a single radio are provided. The exemplary embodiment takes advantage of a standard RANAP signaling procedure called “directed retry” to perform a much better coordination between the change in radio mode and the transfer of the media path. With the use of “directed retry”, the transfer of the media path does not begin until the handover procedure is complete, thus significantly reducing the likely amount of media disruption.
