50results about How to "Increased latency" patented technology

Methods, systems, and devices are described for wireless communication at a user equipment (UE). A wireless communications system may improve UE discovery latency by dynamically selecting and switching beam forming codebooks at the millimeter wave base station and the wireless device. Selecting an optimal beam forming codebook may allow the wireless communication system to improve link margins between the base station without compromising resources. In some examples, a wireless device may determine whether the received signals from the millimeter wave base station satisfy established signal to noise (SNR) thresholds, and select an optimal beam codebook to establish communication. Additionally or alternately, the wireless device may further signal the selected beam codebook to the millimeter wave base station and direct the millimeter wave base station to adjust its codebook based on the selection.

Paging messages are transmitted by a wireless communications network to mobile terminals, which have been in an idle state or dormant mode and which have waiting calls / data from their associated peer entities, in accordance with the qualities of service (QoS) associated with the waiting calls / data, where the QoS associated each waiting call / data includes a type of the call / data. To make paging of mobile terminal QoS aware, a QoS field is included in the Paging Announce requests sent from an RNC to another RNC, or from an RNC to a BTS. The QoS field includes: a QoS class of service of the waiting call / data indicating the type of the waiting call; a grade of service of the waiting call / data to which the mobile terminal is subscribed; and, optionally, other QoS service flow parameters whose presence depends on the type of wireless technology being used in the network.

A frame format used in a wireless communication system, more particularly an OFDMA TDD wireless communication system, of the kind comprising a base station and a plurality of fixed or mobile subscriber stations, the base station maintaining connections with each of the subscriber stations by performing wireless communication in units of frames having said frame format, and within each frame, allocating resources for data transmission and signalling.Each frame has a plurality of downlink subframes and a plurality of uplink subframes including, in time order, a first downlink subframe, a first uplink subframe, a final downlink subframe and a final uplink subframe. One or more further downlink subframe / uplink subframe pairs may be interposed between the first and final subframes as desired, and the configuration can be changed dynamically.The frame structure is capable of adapting to a system that is evolving from supporting predominantly legacy terminals to one which will be supporting an increasing number of enhanced terminals. The coexistence of both legacy and enhanced terminals within the proposed frame structure will have minimal impact of the performance of legacy subscriber stations. Depending on the required number of either legacy or enhanced terminals that need to be supported, the base station has the ability to define a frame configuration where the number of subframes per frame is configured based on the feature set of the operational subscriber stations and the mobility requirements of enhanced subscriber stations such that the frame structure at all times retains sufficient features to support the attachment of legacy stations that do not support the enhanced features.

Solutions to the so-called “man in the middle” problem are disclosed. One example uses a mutually-random value that is the same for each of two communicants absent a man in the middle, but differs between the communicants in case a man-in-the-middle is present. Communicants become aware if their random values differ, for example, through stock content inserted into the communication stream, interactive games, or derived limitations on the channel. In other examples, opening of encrypted parts of the communication is delayed until certain other communication takes place and / or is imminent. In still further examples, a man in the middle becomes apparent because of increased latency of communication between the participants and the effect is optionally accentuated through mutually-random values that shift latency. Further aspects allow parties to apply authentication related to participants they have communicated with when they were convinced that no man in the middle was present. In some examples such communication between common participants is also applied and / or information about the origin of authentication information is hidden.

An apparatus and method for controlling interrupts in a computer are disclosed, in which programmable software operates to control when data concerning the interrupt having highest priority is to be provided, and hardware logic operates to control how that data is provided. An interrupt vector register is included in the computer CPU. The interrupt vector register does not act like the typical register. It is not a physical register, and cannot be written to. A read to this register by the programmable software, triggers the hardware logic. Once triggered, this logic performs certain control tasks, the end result of which is returning to the programmable software, a vector corresponding to the interrupt having highest priority. The programmable software can implement various software policies, in addition to the hardware policy implemented by the hardware logic.

In one embodiment, the LFD is stored locally at the site of each protect agent such that the organization's secure information can be protected even when a protect agent is disconnected from the network. Methods and systems to compress fingerprints to achieve the lightweight fingerprint databases are also provided. In one embodiment, a combined approach, utilizing both the local lightweight fingerprint database and a remote fingerprint server comprising registered fingerprints is used to achieve overall protection of the organization's secure information.

An adaptive retry mechanism may record latencies of recent transactions (e.g. the first data transfer latency), and may select a retry latency from two or more retry latencies. The retry latency may be used for a transaction, and may specify a point in time during the transaction at which the transaction is retried if the first data transfer has not yet occurred. In one implementation, the set of retry latencies includes a minimum retry latency, a nominal retry latency, and a maximum retry latency. The nominal retry latency may be set slightly greater than the expected latency of transactions in the system. The minimum retry latency may be less than the nominal retry latency and the maximum retry latency may be greater than the nominal retry latency. If latencies greater than the nominal retry latency but less than the maximum retry latency are being experienced, the maximum retry latency may be selected. On the other hand, if latencies greater than the maximum retry latency are being experienced, the minimum retry latency may be selected.
