ActiveUS20070285131A1Reducing signal delay timePrevent degradation of outputCurrent/voltage measurementDigital storageAudio power amplifierControl delay
A sense amplifier-based flip-flop includes a first latch, a second latch, a floating reduction unit, an input signal applying unit, a ground switch and a delay reduction unit. The first latch outputs a signal to a first output terminal pair, and outputs an evaluation signal pair corresponding to an input single pair to the first output terminal pair. The second latch latches the evaluation signal pair and outputs the evaluation signal pair to a second output terminal pair. The floating reduction unit is controlled by signals of the first output terminal pair and is operationally connected between current passing nodes of the first latch to prevent the first output terminal pair from floating. The input signal applying unit is disposed between the current passing nodes and a ground terminal, and receives the input signal pair. The ground switch is disposed between the input signal applying unit and the ground terminal, and is controlled by the clock signal. The delay reduction unit is disposed between the input signal applying unit and the ground switch, and reduces a signal delay from when the clock signal to when the evaluation signal pair is output from the second output terminal pair.

In a network supporting transactions between clients and servers and proxies that are interposable in a network path between at least one client and at least one server, wherein a pair of proxies can modify a packet stream between a client and a server such that packet data from the client to the server is transformed at a client-side proxy of the proxy pair and untransformed at a server-side proxy of proxy pair and such that packet data from the server to the client is transformed at the server-side proxy and untransformed at the client-side proxy, a method and apparatus for a discovering proxy to transparently discover its position in a proxy pair by using proxy signals to indicate to other proxies that could pair with the discovering proxy. A discovering proxy might determine that it is a client-side proxy by receipt of a packet from client without a proxy signal. A discovering proxy might determine that it is a server-side proxy by receipt of a packet from server without a return proxy signal. Once a proxy pair is discovered, that proxy pair might transform traffic from the server to the client or vice versa, transforming the traffic at one proxy of the proxy pair and untransforming the traffic at the other proxy of the pair.

Method and Apparatus For Multimodal Voice and Web Services
InactiveUS20090144428A1No setup overheadReduce latencyError preventionFrequency-division multiplex detailsMultiplexerWeb service
This invention is based on being able to locate a voice server, temporarily allocate it, send it the audio of you saying “When is flight 683 due to arrive?”, getting the results of what you said back in the browser, and deallocating the voice server for use by the next person talking into their browser. Voice channels and IVR ports are initially set up by a switch and the IVR using conventional audio protocols. The Voice channels are not initially connected to the client. The switch handles the allocation and deallocation of IVR voice channels without having to communication further with the IVR. A user indicates (usually by pressing a PTT button) to the client device that he wishes to initiate a voice interaction during an X+V session. This translates to a request on the CTRL channel to synchronise the XHTML and VXML forms which the embodiment uses as a trigger for the VXML browser to execute a conversational turn. The multiplexer intercepts this control command and connects the virtual voice circuit between the device and an existing open but unattached voice port. The virtual circuit is connected without having to set up an RTP channel. The CTRL signal is then forwarded to the interaction manager so that the conversation can take place. At the end of the conversation the virtual circuit is disconnected.

Base station based methods and apparatus for supporting break before make handoffs in a multi-carrier system
ActiveUS20050124344A1Reduce delaysReduce latencyRadio/inductive link selection arrangementsRadio transmissionNetwork linkMulti carrier
A mobile communications device initiates a handoff from its current base station (BS) sector network attachment point to a new BS sector. The mobile sends a handoff request over its current wireless link to the current BS sector, which forwards the request to the new BS sector, e.g., via a network link. The new BS sector processes the request assigning dedicated resources, e.g., an identifier and dedicated uplink segments. Information identifying the allocated resources is conveyed from the new BS sector via the current BS sector to the mobile. The mobile determines the time of the allocated dedicated segments based upon a received beacon signal from the new BS sector with known timing relationships to dedicated segments. The mobile breaks the original wireless link just prior to the time of the first assigned dedicated segment. The mobile communicates information on the assigned dedicated segments to perform registration operations, e.g., timing synchronization and power control, establishing a new wireless link.

Rules-based transaction prefetching using connection end-point proxies
ActiveUS20060212524A1Increase speedReduce server latencyMultiple digital computer combinationsTransmissionClient-sideNetwork application
Network proxies reduce server latency in response to series of requests from client applications. Network proxies intercept messages clients and a server. Intercepted client requests are compared with rules. When client requests match a rule, additional request messages are forwarded to the server on behalf of a client application. In response to the additional request messages, the server provides corresponding response messages. A network proxy intercepts and caches the response messages. Subsequent client requests are intercepted by the network application proxy and compared with the cached messages. If a cached response message corresponds with a client request message, the response message is returned to the client application immediately instead of re-requesting the same information from the server. A server-side network proxy can compare client requests with the rules and send additional request messages. The corresponding response messages can be forwarded to a client-side network proxy for caching.

LTE and WLAN interconnecting system and switching method
InactiveCN101841880AMeet business quality requirementsReduce latencyWireless communicationTime delaysCoupling
The invention provides an LTE and WLAN interconnecting system and a switching method; and the system introduces the entity of a virtual base station under an LTE architecture, and accesses the entity into the interface of the LTE as WLAN. On the LTE side, the virtual base station remains transparent relative to the LTE side, and is provided with the functions of a general LTE base station. On the WLAN side, the virtual base station can control the WLAN access point. The switching between the LTE and the WLAN is realized through the virtual base station through a standard X2 interface. A second layer tunneling protocol or an Ethernet tunneling protocol is adopted between the virtual base station and the WLAN access point to realize the transmission and the receiving of data and signaling during the switching process, and the WLAN serves as the bottom layered transmission channel of the data and the signaling of an LTE system. The method has the advantage that for the LTE, the switching process is kept consistent with the LTE switching process, which has very small impact on the traditional LTE. The WLAN is connected with the LTE in a tight coupling way, thereby greatly meeting the business requirement requirements, reducing the time delay caused by system switching, and ensuring the system performance.
