The disclosed methods and apparatus help a mobile radio maintain a radio link by regularly monitoring frame synchronization, regularly checking a scrambling sequence of a mobile radio against that of infrastructure equipment, and regularly detecting and/or recovering from fade conditions. In the event the radio link can not be maintained, then the disclosed methods and apparatus will cause the mobile radio to switch to a control channel so that the synchronization, scrambling mismatch and/or fade issues may be corrected. In one implementation, the disclosed methods and apparatus can be implemented at mobile radios in an Association of Public-Safety Communications Officials (APCO) Project 25 (P25) compliant system.Type: ApplicationFiled: November 30, 2010Publication date: May 31, 2012Applicant: Motorola, Inc.Inventors: James E.

Publication number: 20120134354Abstract: A method and system for handling security synchronization for prolonged periods of no-reception of voice frames. The method includes receiving one or more protocol data units (PDUs) by a radio link control (RLC) sub layer and determining a time period between the receiving of each PDU and a previously received PDU by the RLC sub layer. Further, the method includes initiating recovery procedure for the time period exceeding a first predefined time. The recovery procedure includes identity count of the one or more PDUs to be recovered, deciphering each PDU using a plurality of hyper frame numbers (HFNs) and updating a master HFN based on the deciphering. The master HFN deciphers each PDU among the one or more protocol data units. Further, the method also includes delivering the one or more PDUs to a packet data convergence protocol sub layer where type verification of the PDU is performed.Type: ApplicationFiled: August 23, 2010Publication date: May 31, 2012Applicant: SAMSUNG ELECTRONICS CO., LTD.Inventors: Kundan Kumar Lucky, Gert-Jan Van Lieshout

Publication number: 20120134356Abstract: According to an example embodiment, a technique may be provided for managing a label data base of which each entry comprises a data field for insertion into a respective packet in a multicast transmission and a validity field. The technique may include, for example, (a) establishing a fixed size for a cluster of labels, (b) associating with each cluster a pointer to another cluster, (c) establishing a sentinel cluster of which all entries are indicated to be invalid and of which the cluster pointer points to this sentinel cluster, (d) establishing a root table which defines the number of replications of the packet in a multicast group and identifies a first label cluster associated with the multicast group and (e) establishing a chain of clusters of which each cluster which is full of valid entries points to the next cluster in the chain and the last cluster which contains valid entries points to the sentinel cluster.Type: ApplicationFiled: May 27, 2011Publication date: May 31, 2012Applicant: BROADCOM CORPORATIONInventors: Vincent Groarke, Anne Geraldine O'Connell

Publication number: 20120134357Abstract: Forwarding state is installed for sparse multicast trees in a link state protocol controlled Ethernet network by enabling intermediate nodes to install state for one or more physical multicast trees, each of which may have multiple logical multicast trees mapped to it. By mapping multiple logical multicasts to a particular physical multicast, and installing state for the physical multicast, fewer FIB entries are required to implement the multiple multicasts. Mapping may be performed by destination nodes before advertising membership in the physical multicast, or may be performed by the intermediate nodes before installing state when a destination node advertises membership in a logical multicast. Intermediate nodes will install state for the physical multicast tree if they are on a shortest path between a source and at least one destination of one of the logical multicasts that has been mapped to the physical multicast.Type: ApplicationFiled: November 22, 2011Publication date: May 31, 2012Applicant: ROCKSTAR BIDCO LPInventors: Peter ASHWOOD SMITH, Guoli YIN, Hong ZHANG, Nigel BRAGG, David ALLAN

Publication number: 20120134358Abstract: According to certain embodiments, control packets are received through a control plane tunnel that communicates control traffic for virtual private networks (VPNs) among autonomous systems. A routing instance of each control packet is identified according to a control tag of the control packet. At least two routing instances are distinct from each other. The control packets are routed according to the routing instances. According to certain embodiments, data packets are received through a data plane tunnel that communicates data traffic for the VPNs among the autonomous systems. A forwarding instance of the control packet is identified for each data packet according to a data tag of the data packet. At least two forwarding instances are distinct from each other. The data packets are forwarded according to the forwarding instances.Type: ApplicationFiled: November 30, 2010Publication date: May 31, 2012Applicant: Cisco Technology, Inc,Inventors: Patrice Bellagamba, Victor M.

Publication number: 20120134359Abstract: A switch includes a plurality of port units, a tag attaching unit, a switching unit, and a tag removing unit. Each of the plurality of port units includes a port configured to receive a packet or transmit a packet. The tag attaching unit determines a sub-group identifier on the basis of an input port identifier for identifying an input port which has received an input packet and a group identifier included in the input packet for identifying a group of ports, and attaches a sub-group tag including the determined sub-group identifier to the input packet to acquire an augmented packet. The switching unit determines an output port for outputting the input packet on the basis of the determined sub-group identifier, the group identifier, and a destination address included in the augmented packet. The tag removing unit removes the attached sub-group tag from the augmented packet to acquire the input packet.Type: ApplicationFiled: September 8, 2011Publication date: May 31, 2012Applicant: FUJITSU LIMITEDInventor: Yukihiro NAKAGAWA
