摘要： Techniques for performing timer-based sleep to extend sleep time and thus battery life for a terminal in a wireless communication system. The likelihood of data traffic may be related to recent usage. If recent usage indicates that data traffic is unlikely, then the terminal can continue to maintain the link but monitor the signals from the system at a reduced rate. In one method, the probability of data traffic for the terminal is initially estimated (514) (e.g., based on time since last activity and a particular usage model). A timer value is then determined based on the estimated probability of data traffic (516). The timer value may be modified based on an event, which may relate to link maintenance, hand-off, and so on (518). Sleep is then performed for the duration corresponding to the unmodified or modified timer value (520) and may extend past one or more designated paging slots.

摘要： An HDLC accelerator includes a deframer and framer to respectively accelerate the deframing and framing processes for PPP packets. The deframer includes an input interface unit, a detection unit, a conversion unit, and an output interface unit. The input interface unit receives a packet of data to be deframed. The detection unit evaluates each data byte to detect for special bytes (e.g., flag, escape, and invalid bytes). The conversion unit deframes the received data by removing flag and escape bytes, "un-escaping" the data byte following each escape byte, providing a header word for each flag byte, and checking each deframed packet based on a frame check sequence (FCS) value associated with the packet. The output interface unit provides deframed data and may further perform byte alignment in providing the deframed data. A state control unit provides control signals indicative of specific tasks to be performed for deframing.

摘要： A system and method for determining 1xEV-DO availability for a packet data call in a wireless device is presented. When the wireless device receives a request to initiate a packet data call, the device determines if it currently has access to a preferred 1xEV-DO channel. The determination can be made by consulting a 1xEV-DO availability list stored in persistent memory on the wireless device. If available, the wireless device originates the packet data call on the 1xEV-DO channel. If the device is using a CDMA system that has 1xEV-DO channels but the availability or usability of those channels are unknown, the device polls the signal strength on the 1xEV-DO channels to determine the best 1xEV-DO channel to use for the packet data call. If no 1xEV-DO channel is available or if none of the available 1xEV-DO channels are usable, then the device originates the packet data call on a CDMA channel.

摘要： Techniques to efficiently attempt acquisition of a packet data system (e.g., an IS-856 system). If a terminal has acquired one or more channels in a voice/data system (e.g., an IS-2000 system), then it can attempt acquisition on channels in the packet data system that are co-located with the acquired channels in the voice/data system. Multiple acquisition modes may be used, and on-going acquisition attempts on the co-located channels may be performed using one acquisition mode at a time in order to reduce power consumption. Acquisition attempts may be performed in a "ping-pong" manner to improve the likelihood of acquisition. For a ping-pong search, an acquisition attempt is made on the most recently acquired channel prior to an acquisition attempt on each of the remaining channels. Received signal strength estimates may also be obtained for selected channels and may be used to determine whether or not to attempt acquisition on these channels.
摘要翻译：有效地尝试采集分组数据系统（例如，IS-856系统）的技术。如果终端已经在语音/数据系统（例如，IS-2000系统）中获取了一个或多个信道，则它可以尝试在分组数据系统中与语音/数据系统中所获取的信道共同位置的信道上的采集，数据系统可以使用多个采集模式，并且可以一次使用一个采集模式来执行同位置信道上的持续采集尝试，以便降低功耗。收购尝试可以以“乒乓”方式进行，以提高获取的可能性。对于乒乓搜索，在对每个剩余通道进行获取尝试之前，在最近获取的通道上进行采集尝试。也可以对所选择的信道获得接收的信号强度估计，并且可以用于确定是否尝试在这些信道上进行采集。

摘要： To access a first communication system, a terminal determines a transmission time for an access probe, an expected response time from the system, and a protected time interval based on the transmission time and/or expected response time. The terminal determines a starting time for sending the access probe such that the protected time interval does not overlap a tune-away interval in which the terminal is to monitor anther frequency/air-interface. This starting time may be set initially to the end of a prior access probe plus a pseudo-random wait duration and may be advanced forward or moved backward in time, if needed, by a time duration selected such that the protected time interval does not overlap the tune-away interval.

摘要： A hybrid access terminal is a Wireless Communication Device (WCD) capable of operating over different types of communication networks. An exemplary WCD operates on both IS-2000 and IS-856 networks, and is capable of inter-system handoffs between these two types of networks. Such capabilities enable the exemplary WCD to provide voice, data and short messaging services on IS-2000 networks, and also to provide high speed packet data service on IS-856 networks. A method of operating on different networks includes establishing a data session on the first network, detecting a request for a packet data service, handing-off the data session to a second network, detecting a dormancy of the data session, transitioning to a dormant state and initiating a Dormancy time-out period when the dormancy is detected, and monitoring both the first network and the second network for paging messages while in the dormant state.

摘要： A method and system for transferring data bytes includes a first memory adapted to store a plurality of multiple-byte data words including header field bytes and one or more data field bytes. The system also includes a second memory adapted to store data field bytes transferred thereto from the first memory. A controller coupled to the first and second memories reads a data word including the header field byte and the one or more data field bytes out of the first memory. The system also includes a data packer coupled to the controller and the second memory. The controller and data packer cooperate to transfer the one or more data field bytes of the first data word read from the first memory to the second memory. The data packer stores only the one or more data field bytes in the second memory contiguously with a previously transferred and stored data field byte.

摘要： Multiple applications sharing common resources are arbitrated such that failures resulting from unavailable resources can be avoided. Whenever an application (e.g., a data application) desires to perform an operation (e.g., PPP resynchronization) that requires the use of a shared resource (e.g., an RF receiver), a determination is made as to whether that resource is available. The operation may be delayed while the resource is unavailable. The application may be assigned the resource if it is available or becomes available and may then start the operation. The resource is locked while the operation is pending to avoid assignment to another application. The resource arbitration allows applications to complete their operations without encountering failures due to other applications taking over the resources.
摘要翻译：仲裁共享资源的多个应用程序，从而可以避免由不可用的资源引起的故障。每当应用（例如，数据应用）期望执行需要使用共享资源（例如，RF接收机）的操作（例如，PPP重新同步））时，确定该资源是否可用。当资源不可用时，操作可能会延迟。如果应用程序可用或可用，则可以为该应用程序分配资源，然后可以开始该操作。当操作正在等待以避免分配给另一个应用程序时，资源被锁定。资源仲裁允许应用程序完成其操作，而不会因其他应用程序接管资源而遇到故障。
