摘要： An apparatus and a method are provided for improving user experience in a multi-radio access bearer (multi-RAB) wireless communication system. After a user equipment establishes a circuit-switched communication link and a packet-switched communication link with a core network, it may receive an indication of an error associated with the packet-switched communication link. Here, if the value of a timer such as the RAB re-establishment timer T314 has a predetermined value (e.g., 0), the user equipment may release the packet-switched communication link, and maintain the circuit-switched communication link. The packet-switched communication link may then be re-established. In this fashion, errors that may occur on the data call need not interrupt a voice call.

摘要： This disclosure is generally directed to communication systems, devices used in communication systems and associated methods which may implement parallel hypothesis search techniques. The disclosed parallel hypothesis search techniques may permit a hypothesis to be dismissed early (i.e., before hypotheses in other searchers have completed their evaluation). Early hypothesis dismissal permits a new hypothesis to be loaded into the searcher while other searchers advantageously continue to evaluate their hypotheses.
摘要翻译：本公开通常涉及通信系统，在通信系统中使用的设备和可以实现并行假设搜索技术的相关方法。公开的平行假设检索技术可以允许早期解除假设（即，在其他搜索者的假设已经完成其评估之前）。早期假设解雇允许将新假设加载到搜索者中，而其他搜索者有利地继续评估其假设。

摘要： System and method for performing symbol boundary aligned searches of signals. A preferred embodiment comprises a search control unit (such as search control unit 725) that can determine a start and stop condition for a correlation based on a hypothesis, a searcher (such as searcher 705) which includes a multiplexer that can select a subset of samples of a received sequence based on the hypothesis and start and stop conditions. The search control unit can then wait for the occurrence of the start condition and assign the hypothesis to a correlator, which will correlate the subset of samples with a locally generated pseudo-random number sequence based upon the hypothesis.

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： A method and system for processing the results of searches for signals in a direct sequence spread spectrum communications system in an intelligent and efficient manner. A preferred embodiment comprises a search engine (for example, search engine 405) and a hardware result processor (for example, result processor 410) with a memory (for example, memory 415) as an interface. The search engine may perform multiple correlations of a pilot channel and then writes the correlation results exceeding a specified threshold to the memory. The result processor reads the correlation results from the memory and performs result filtering and builds a list of maximum value correlation results. The result processor and the search engine functions with independence from one another therefore, there is therefore, little wasted overhead where one has to wait for the other. The result filtering also makes it simpler to combine signal multipaths and simplifies pilot channel strength comparisons.
