Patent number: 8320398Abstract: Systems and methodologies are described that facilitate paging a peer in a peer-to-peer communication network. Paging messages may be communicated directly between a wireless terminal and its peer(s). Further, the wireless terminal may monitor for incoming paging messages during subinterval(s) of a paging interval as a function of an identifier of the wireless terminal. Moreover, the wireless terminal may transmit a paging message to a peer (e.g., detected and/or identified during peer discovery) during subinterval(s) of the paging interval as a function of an identifier of the peer.Type: GrantFiled: July 10, 2007Date of Patent: November 27, 2012Assignee: QUALCOMM IncorporatedInventors: Junyi Li, Rajiv Laroia

Publication number: 20120294317Abstract: Aspects of the disclosure provide a method for network traffic scheduling. The method includes selecting, at a present node within a node hierarchy that multiplexes a plurality of input nodes to an output node, a winning node from a plurality of lower level nodes, obtaining first parameters provided from the winning node, the first parameters being in association with the winning node, determining second parameters in association with the present node at least partially based on the first parameters, and providing the second parameters in association with the present node to an upper level node in the node hierarchy for scheduling at the upper level node. To determine the second parameters in association with the present node, in an embodiment, the method includes using the first parameters to look up an entry in a lookup table that stores the second parameters in association with the first parameters.Type: ApplicationFiled: May 18, 2012Publication date: November 22, 2012Inventors: Sarig Livne, Vitaly Sukonik, Einat Ophir

Patent number: 8315271Abstract: An IBSS that allows token passing for round-robin service of QoS flows is disclosed (an RRBSS). The RRBSS permits low-latency, reduced contention, distributed scheduling useful in any ad hoc network, but particularly suitable for high data rates. Distributed scheduled access is provided for flows through a round-robin token passing service discipline. STAs follow a round-robin order, or list, and are able to communicate with round-robin transmit opportunities during a defined period. Each STA in the list transmits a respective token to transfer access to the shared medium to the next STA in the RR List. The sequence is terminated with an end token. STAs maintain station identifiers and list updates are maintained with a sequence identifier. Techniques are disclosed to add and remove STAs to the sequence; establish connectivity lists (receive and forward), and maintain other sequence parameters such as bandwidth management and TXOP duration. Various other aspects are also disclosed.Type: GrantFiled: March 23, 2005Date of Patent: November 20, 2012Assignee: Qualcomm IncorporatedInventors: Sanjiv Nanda, Jay Rodney Walton

Patent number: 8315275Abstract: Apparatus and methods are provided for delivering end-to-end Quality of Service (QoS) over Internet Protocol (IP) networks. According to one embodiment, a portion of available bandwidth between a first and second network device is reserved as a Quality of Service (QoS) resource pool for real-time communication sessions among users of a first and second user community. The first network device is communicatively coupled with a packet network and associated with the first user community. The second network device is communicatively coupled with the packet network and associated with the second user community.Type: GrantFiled: August 10, 2009Date of Patent: November 20, 2012Assignee: Prom KS Mgmt Limited Liability CompanyInventor: Siddhartha Nag

Patent number: 8310352Abstract: While ECUs are connected with a distribution apparatus via a communication line, each of the ECUs sends status notification representing own status to the distribution apparatus. The distribution apparatus creates status information representing status of the ECUs in accordance with status notifications received from the ECUs connected with the distribution apparatus. This status information is sent to other distribution apparatuses together with data for synchronizing a database. The other ECUs perform similar operations to those of the ECUs, while the other distribution apparatuses perform similar operations to those of the distribution apparatus. Therefore, each of the distribution apparatuses can recognize the status of all the ECUs.Type: GrantFiled: August 22, 2008Date of Patent: November 13, 2012Assignees: Autonetworks Technologies, Ltd., Sumitomo Wiring Systems, Ltd., Sumitomo Electric Industries, Ltd.Inventor: Yukihiro Miyashita
