摘要： Data transfer rates on a network are controlled in conjunction with TCP/IP protocols by limiting the available space in a receive buffer located on the receiver. Limits are generated by either moderating the rate that data is removed from the receive buffer or changing the receive buffer's size. Transfer rates are reduced to decrease the impact large transfers have on other network traffic and to reduce the total number of lost data packets. Reduced rates and priorities can be managed by scheduling systems.

摘要： A method for processing data packets in an interception proxy server without using a Network Address Translation module. A TCP packet received at a router is encapsulated using generic routing encapsulation (GRE). The TCP packet is redirected to a proxy server through a GRE tunnel which includes a redirection rule comprising a local destination IP address and port to be used for traffic passed through the tunnel. When the proxy server receives the TCP packet, the TCP packet is decapsulated. If a flag is set in the payload header of the TCP packet indicating that a redirection rule has been configured for traffic passed through the tunnel, the payload header of the TCP packet is modified according to the redirection rule. The modified TCP packet is then passed to a transmission control protocol of the proxy server.

摘要： An intelligent information router system comprising a telephony controller coupled to a private branch exchange through a link interface. The telephony controller may communicate with a handle manager and a script interpreter engine. The telephony controller may receive information from the link interface regarding telephone calls being placed to the private branch exchange. The telephony controller may initiate actions with the script interpreter engine that access information stored in a database through a database controller. In response to action of the script interpreter engine, the telephony controller may instruct the private branch exchange to route the call to an appropriate location within a company depending on the information received by the private branch exchange through automatic transmission of data or interaction with the calling party.

摘要： Sub-channels in cells of an Orthogonal Frequency Division Multiple Access (OFDMA) network are formed based on random permutations of a set of subcarrier indices. The random permutations are performed for each cell of the network using a pseudo-random number generator (PRNG) and a shuffle technique. Different initial states of the PRNG are used to generate the random permutation of the subcarrier indices for each cell. In an embodiment, sub-carriers represented by a contiguous group of indices in the random permutation obtained for a cell are assigned to form a sub-channel. Interference diversity for the OFDMA network is thereby improved.

摘要： Methods and systems for synchronizing wireless transmission of data packets is provided. Signals having a data packet frame format including a preamble (with a pattern of symbol sequences) and data are received, and patterns of symbol sequences are correlated. A first metric can be calculated that is a ratio of an average of the correlation values and an average of a power of the signals. A second metric can be calculated that defines an average of a power of noise in the signals. The methods include determining an approximate division of the preamble and data in the data packet of each signal based on the first and second metrics. The methods further include determining a cross-correlation between versions of a transmitted signal to produce a number of peaks equal to a number of transmit antennas, generating a third metric based on combinations of cross-correlations, and identifying a position of a maximum peak within the third metric as a fine timing offset amount.

摘要： A system and method of retrieving customer records regardless of area code change affecting customer telephone numbers stored in customer records is provided. The method begins by providing an area code changes user interface on a system user display, which is configured to accept area code changes input by the system. Area code changes, which include actual area codes and old area codes are input using the interface. Next, each input area code change is stored in an area code changes memory. An ANI string corresponding to an incoming telephone call is then received and at least one customer record database is searched to identify any call records that include a telephone number corresponding to the ANI string. If no customer records are identified, then the area code changes memory is searched to identify if the ANI string includes an area code corresponding to an actual area code stored in the area code changes memory. If an actual area code match is found, then the ANI string is modified by replacing the area code included in the ANI string with the old area code corresponding to the actual area code stored in the area code changes memory. The customer record database search is then repeated until there are no more actual area codes stored in the area code changes memory that correspond to the area code included in the ANI string.

摘要： Methods and systems for detecting a preamble of a data packet in wireless communication systems is provided. To determine a preamble from a received signal, which may include a noise-altered preamble bit sequence, linear feedback shift registers (LFSRs) can be used to generate a count of the received preamble, and the count is compared to pre-generated scores to identify a match. Example methods include for each of a number of different preamble orientations of a preamble, generating a count value based on a comparison of bits of the preamble with a random bit sequence to produce a sequence of count values, and comparing the sequence of count values with m sequences of count values. A sequence of count values is identified that includes a maximum number of matching elements, and the received preamble is determined to be one of the m preambles corresponding to the identified sequence.
