Patent number: 7995605Abstract: The present invention describes a communications system having a first link partner and a second link partner that are connected by a communications link having at least four pairs of conductors. According to IEEE Standard 802.3 (e.g. Ethernet) for 1000Base-T, a data link is maintained (in a period absent data transmission) by sending idle signals over four pairs of conductors of the cable to maintain a logical connection. This idle signal scheme is replaced with an alternate idle signaling scheme that uses only two pairs of conductors to maintain a logical connection and therefore can operate with using lower power. The other two pairs of conductors of the four pairs of conductors are unused to maintain a logical connection absent data transfer, and therefore can be used to implement a Suspend Mode of operation. During Suspend Mode, the physical layer of each link partner powers down unnecessary circuitry so as to operate in a low power environment.Type: GrantFiled: May 18, 2010Date of Patent: August 9, 2011Assignee: Broadcom CorporationInventors: Richard G.

Patent number: 7990998Abstract: A user terminal establishes a session with a first access point (AP0) and obtains a token associated with modem configuration information used for radio communication. The user terminal thereafter establishes a connection with a second access point (AP1) by sending the token. AP1 receives the token, obtains the modem configuration information associated with the token, and initializes an air interface protocol stack with the modem configuration information to obtain a modem-specific protocol stack for the user terminal. AP1 sends a response indicating successful connection setup. The user terminal and AP1 thereafter communicate in accordance with the modem-specific protocol stack. AP1 may attempt to fetch the session for the user terminal from AP0. If this is successful, then AP1 updates the protocol stack with the session information to obtain a complete protocol stack for the user terminal. The user terminal and AP1 thereafter communicate with the complete protocol stack.Type: GrantFiled: March 22, 2005Date of Patent: August 2, 2011Assignee: QUALCOMM IncorporatedInventors: Rajat Prakash, Gavin Bernard Horn, Nikhil Jain, Ramin Rezaiifar

Patent number: 7987488Abstract: A system for transmitting and receiving image and audio data that is information on any of image and audio has a transmission apparatus and a reception apparatus. The transmission apparatus transmits the image and audio data using a multi-channel communication system and includes a first protocol conversion device. The reception apparatus receives the image and audio data using the multi-channel communication system and includes a second protocol conversion device. The transmission apparatus performs data conversion processing on the image and audio data by the first protocol conversion device using a protocol to produce parallel image and audio data, and transmits it to the reception apparatus using the multi-channel communication system. The reception apparatus receives the parallel data to perform data conversion processing on the parallel data using the protocol by the second protocol conversion device to return to the image and audio data.Type: GrantFiled: August 24, 2006Date of Patent: July 26, 2011Assignee: Sony CorporationInventors: Masaya Mouri, Kenichi Sakusabe

Patent number: RE42850Abstract: In a system for sharing hybrid resources in an independent network, each one of a plurality of stations preferably employs a sharing authority transferring protocol that allows the network control function to be moved from station to station depending on the network traffic. Although a distributed coordination method is normally used in the network, when an individual station determines that a real-time data stream is intended for the station, an apparatus having a method and data format for the use thereof allows control to be transferred to the targeted station. This allows the targeted station to control the sharing of the wireless hybrid resources using a centralized control method in a direct mode for the duration of the real-time service transmission, thereby optimizing network efficiency. As a result of using the distributed control authority of the present invention, a station may be freely subscribe/withdraw to/from the network.Type: GrantFiled: March 5, 2010Date of Patent: October 18, 2011Assignee: Samsung Electronics Co., Ltd.Inventor: Kyung-hun Jang
