The payload is sent to a destination address via a network. Payloads may also be received at the media gateway server, portioned, distributed to the first mobile device, reconstructed and delivered to the access device in a similar manner. | 2011-02-10 |
20110032915 | LOCAL WIRELESS COMMUNICATION SYSTEM AND METHOD EMPLOYING FREQUENCY-VARIABLE SIGNAL DETECTION - A system for performing a local wireless communication using a predetermined frequency band divided into a plurality of channels. The system includes a hub for scanning each channel to identify available one of the plurality of channels and transmitting data over the available channel. The system further includes a sensor set to start to operate when the sensor detects a signal within the predetermined frequency band. The sensor spectrum-senses the signal of the frequency band for each channel, and analyzes a header of packet data for each channel, and receives and processes the packet data if the signal is identified to have a designated code. | 2011-02-10 |
20110032916 | WIRELESS COMMUNICATION APPARATUS AND METHOD USING THE SAME - The present invention discloses a wireless communication method for transceiving packets in wireless networks. The method comprises the steps of: transmitting a first packet with a first packet format, wherein a header of the first packet with the first packet format comprises information of a first communication duration; and performing a communication procedure during the first communication duration for transmitting at least one second packet with a second format, for receiving at least one third packet with the second format, or for both transmitting the at least one second packet and receiving the at least one third packet. | 2011-02-10 |
20110032917 | METHOD AND DEVICE FOR THE RELIABLE TRANSMISSION OF COMPRESSED NETWORK HEADERS - Method for transmitting data in a transmission system, the data being transmitted in the form of packets including a compressed header field and a data field and according to a format suited to the transmission system comprising the following steps: recovering the data packet to be transmitted including a compressed header and useful data, identifying the header part from the useful-data part, applying a corrector coding which is selected at the level of the header, and providing the resulting new packet to the link layer, while also communicating the protection mode used, generating the link header according to the transmission format of the relevant transmission system integrating the mode of protection used, and the adaptation of the CRC checksum of the link layer, on reception, performing the error corrector decoding in two steps. | 2011-02-10 |
20110032918 | COMMUNICATION APPARATUS AND CONTROL METHOD THEREFOR - A communication apparatus decides whether to provide, to a receiving apparatus that receives provided communication parameters, communication parameters that have been set by a communication-parameter setting process performed with another communication apparatus. When it is determined to provide the set communication parameters, a parameter that controls sending of an informing signal is changed in order to increase the number of informing signals sent by the communication apparatus per unit time. | 2011-02-10 |
