Systems and methods enabling search of a repository for the location of data that is similar to input data, using a defined measure of similarity, in a time that is independent of the size of the repository and linear in a size of the input data, and a space that is proportional to a small fraction of the size of the repository. Additionally, remote operations are accomplished with significantly reduced system bandwidth by implementing remote differencing operations.

A communication method for a communication network includes transmitting first control information for a first frame from a hub to a plurality of user nodes, and transmitting a first data burst in the first frame from a first user node and a second data burst in the first frame from a second user node to the hub according to the first control information. A start of the first frame from the first and second user nodes occurs simultaneously at the hub. The method also includes transmitting second control information for a second frame from the hub after transmitting the first control information, transmitting a third data burst in the second frame to the hub according to the second control information, and receiving the second frame at the hub following the first frame.

The invention relates to a method for the transfer of policy control information during handover in a communication system. A session between a terminal and a remote node via a first network node has been established previously. The session comprising media components transmitted via the first gateway using first media component bearers. A handover condition is detected and a signaling connection is established between the terminal and the second gateway. Information on a second network node is obtained by the terminal, which determines if a proxy for the session has changed. If it has, information on media components is sent to a policy decision entity associated with the second network node. The policy decision entity authorizes second media component bearers with the information provided. Finally, the second media component bearers are established between the terminal and the second gateway.

An Ethernet based vehicle network message transferring system is provided that includes a gateway switch that connects the Ethernet to vehicle networks having different protocols and an Ethernet switch that switches Ethernet messages between the gateway switch and vehicle devices to transfer the Ethernet messages. The Ethernet switch includes a processing module that transfers the Ethernet messages received via the gateway switch in the different vehicle networks, a vehicle network process module that switches the messages transferred from the processing module, and a lookup table in which information necessary for switching the vehicle network process module is stored. The vehicle network process module analyzes an Ethernet message transferred via the processing module in the gateway switch to identify destinations of individual messages in the Ethernet message and divides the Ethernet message including information regarding the individual message according to destinations to transmit the divided Ethernet messages to vehicle devices of destinations.

A mapping table loading method, a memory control circuit unit and a memory storage apparatus are provided. The method includes: receiving a first command; loading a first sub-logical address-physical address mapping table corresponding to the first command if an operating mode of a non-volatile rewritable memory module is a first operating mode; and loading a first logical address-physical address mapping table corresponding to the first command if the operating mode of the non-volatile rewritable memory module is a second operating mode, wherein the first logical address-physical address mapping table includes the first sub-logical address-physical address mapping table.

A numerical controller is chain-connected with a plurality of I / O units so that it transmits DI / DO signals to and receives DI / DO signals from the I / O units by master-slave communication. The numerical controller counts signals generated by a timer circuit up to a predetermined number and sets, from among the plurality of I / O units, an I / O unit with which transfer of the DI / DO signals is to be performed for each count value. The DI / DO signals of the set I / O units are transferred according to the count value.

The invention discloses a method for controlling reading transfer among buses with different speeds, which includes following steps that a lateral interface of a bridge equipment B-class bus sends a B-class bus reading request of data on one side of an A-class bus requested by equipment on a B-class bus, sends an address of the reading request of the B-class bus and data identification to requestFIFO, reads request data from reading FIFO and returns the data to the equipment on the B-class bus; and a lateral interface of a bridge equipment A-class bus takes out the reading request of the B-class bus after seeing the reading request of the B-class bus from the request FIFO, begins to send reading request of an A-class bus on the A-class bus, performs data prefetch of two stages for reading data request by reading request of the B-class bus, and sends the reading data returned from the A-class bus to the reading FIFO.

The application discloses a voice data processing method, system and medium, belonging to the technical field of bluetooth audio data processing. The method includes: analyzing the current audio frame to be encoded, and determining the encoding bit rate corresponding to the current audio frame, the encoding bit rate includes a full bit rate, a medium bit rate and a low bit rate, wherein the full bit rate is greater than the medium bit rate, and the medium bit rate The rate is greater than the low bit rate; the number of retransmissions is set according to the encoding bit rate, where the encoding bit rate is positively correlated with the number of retransmissions; the current audio frame is encoded according to the encoding bit rate, and the encoding result is transmitted. According to the characteristics of the audio frame, the present application selects the corresponding encoding rate to encode the audio frame, and sets different retransmission times correspondingly. It reduces the number of retransmissions or even does not retransmit some audio frames for which there is no valid voice, avoiding wasting audio transmission bandwidth, reducing power consumption and delay.
