Patent number: 8542663Abstract: The present invention provides a way of placing a physical layer device into a standby mode. After a link is established between multiple devices, a determination is made whether the device has data to transmit or whether a standby request was received from a link partner. If a standby request was received or the device has no data to transmit, standby mode is entered. In standby mode, unneeded circuitry is powered down. A transmitter in a channel and a receive path in a separate channel remain powered. While operating in standby mode, the PHY layer continuously transmits a standby code on the one or more channels that are not powered down. Standby mode is discontinued when a transceiver has data to transmit or when energy is detected on the powered down channels. Standby mode is also discontinued when no standby code is received, indicating a disconnect between devices.Type: GrantFiled: July 2, 2004Date of Patent: September 24, 2013Assignee: Broadcom CorporationInventors: Kevin Brown, Richard G.

The communication channel may include a PDP context. The second network element may be one of an SGSN, a GGSN, or an RNC. The first network element may include an MS.Type: GrantFiled: April 9, 2001Date of Patent: October 23, 2012Assignee: Nokia CorporationInventors: Tuija Hurtta, Marc Greis

Patent number: 8290342Abstract: A computer implemented method and apparatus for managing digital video recorder storage for one or more users. Each user in the multi-user environment is assigned an amount of program storage in the digital video recorder. Responsive to receiving a request to record a new program from a user in the multi-user environment, an associated amount of program storage assigned to the use is determined. Responsive to a determination that addition of the new program will not exceed the associated amount of program storage assigned to the user, the new program is recorded to the program storage.Type: GrantFiled: April 23, 2009Date of Patent: October 16, 2012Assignee: International Business Machines CorporationInventors: Kulvir Singh Bhogal, Gregory Jensen Boss, Rick Allen Hamilton, II, Brian Marshall O'Connell

Patent number: 8259661Abstract: Mechanisms, in a transmission channel shared by 802.11 systems and HIPERLAN/2 systems are provided to prevent 802.11 terminals from transmitting during time periods allocated to HIPERLAN, so that a single channel can be shared between the two standards. In a particular embodiment, a “super frame” format is used where HIPERLAN transmissions are offered the highest level of protection possible within 802.11, which is needed within the 802.11 Contention Free Period (CFP).Type: GrantFiled: October 7, 2008Date of Patent: September 4, 2012Assignee: AT&T Intellectual Property II, LPInventor: Matthew J.

Patent number: 8259662Abstract: A method and apparatus for dynamically assigning persistent resources in a wireless communications system is provided. A method comprises transmitting a first boundary indication to a mobile station, and transmitting a position indication to the mobile station, wherein the position indication corresponds to a network resource assigned based on a network resource request, the position indication is relative to the first boundary indication. The method also comprises transmitting a second boundary indication to the mobile station in response to detecting a change in a position of a boundary, and transmitting a first transmission to the mobile station using a network resource corresponding to the position indication or receiving a second transmission from the mobile station using a network resource corresponding to the position indication, wherein the position indication is relative to the second boundary indication. The first boundary indication is based on a position of the boundary.Type: GrantFiled: February 19, 2009Date of Patent: September 4, 2012Assignee: FutureWei TechnologiesInventors: Jack Smith, Sean Michael McBeath

Patent number: 8243747Abstract: A system and method for scalable multifunctional network communication between presentation devices and service providers are disclosed. A group of consumer premise equipment (CPE) units are coupled to the presentation devices, and a headend control computer receives upstream messages from the CPE units and for sending downstream messages to the CPE units. A group of service provider control subsystems interface between the headend control computer and the service providers. The head end control computer receives messages from the CPE units and transports them to the service provider control subsystems, and the headend control computer receives messages from the service provider control subsystems and transports them to the CPE units.Type: GrantFiled: March 25, 2005Date of Patent: August 14, 2012Assignee: La Jolla Networks, Inc.Inventors: James C. Tiernan, Jonathan Fellows

Patent number: 8228846Abstract: To prevent a collision from occurring at the time of random access in cases such as handover, response to paging and the like where a mobile station apparatus performs random access in response to directions from a base station apparatus. In a mobile communication system in which a mobile station apparatus 200 uses a signature of a beforehand determined signature group at the time of random access with a base station apparatus 100, the signature group is comprised of a signature group managed by the base station apparatus 100 and another signature group managed by the mobile station apparatus 200. The signature group managed by the base station apparatus 100 includes signatures associated with particular random access reasons to be selected by the base station apparatus 100.Type: GrantFiled: August 31, 2009Date of Patent: July 24, 2012Assignee: Sharp Kabushiki KaishaInventors: Yasuyuki Kato, Shohei Yamada, Wahoh Oh

Patent number: 8228890Abstract: A method is provided for allocating a radio resource in a packet switched data transmission system, such as GPRS (General Packet Radio Service), which data transmission system includes terminals and a network. In the method, terminals communicate with the network over the radio interface using the packet transfer mode, and for communication, a radio resource is allocated to the terminal. For allocating the radio resource, for the packet switched implementation of a realtime service, a first message is transmitted from the terminal to the network and the first message is received in the network. The network identifies the first message as a radio resource request for the packet switched implementation of a realtime service and allocates to the terminal the requested radio resource for the packet switched implementation of the realtime service. A wireless terminal and network element relating to the method are also provided.Type: GrantFiled: March 12, 2008Date of Patent: July 24, 2012Assignee: Nokia CorporationInventors: Arto Leppisaari, Juha M Kalliokulju

Patent number: 8189514Abstract: A method and apparatus for requesting and allocating bandwidth in a broadband wireless communication system. The inventive method and apparatus includes a combination of techniques that allow a plurality of CPEs to communicate their bandwidth request messages to respective base stations. One technique includes a “polling” method whereby a base station polls CPEs individually or in groups and allocates bandwidth specifically for the purpose of allowing the CPEs to respond with bandwidth requests. The polling of the CPEs by the base station may be in response to a CPE setting a “poll-me bit” or, alternatively, it may be periodic. Another technique comprises “piggybacking” bandwidth requests on bandwidth already allocated to a CPE. In accordance with this technique, currently active CPEs request bandwidth using previously unused portions of uplink bandwidth that is already allocated to the CPE.Type: GrantFiled: June 29, 2005Date of Patent: May 29, 2012Assignee: Wi-LAN, Inc.Inventors: Kenneth L.
