Patent number: 9942873Abstract: Performing concurrent data communication and voice call monitoring using a single cellular radio. According to some embodiments, the UE may perform data communication, via the radio, using a first RAT, supported by a first SIM. The UE may also perform paging functions for a voice communication, via the radio, using a second RAT, supported by a second SIM. In some scenarios, the first and second RATs are the same. The data communication and the paging functions may be performed concurrently using shared physical layer resources. For example, the shared physical layer resources may comprise a shared software defined radio (SDR) configured to demodulate and/or decode signals of the data communication and the paging function. As another example, the shared physical layer resources may comprise a shared Rake receiver configured to demodulate signals of the data communication and the paging function.Type: GrantFiled: July 23, 2015Date of Patent: April 10, 2018Assignee: Apple Inc.Inventors: Johnson O.

Patent number: 9936077Abstract: A system and method are presented for the encoding of participants in a conference setting. In an embodiment, audio from conference participants in a voice-over-IP setting may be received and processed by the system. In an embodiment, audio may be received in a compressed form and de-compressed for processing. For each participant, return audio is generated, compressed (if applicable) and transmitted to the participant. The system may recognize when participants are using the same audio encoding format and are thus receiving audio that may be similar or identical. The audio may only be encoded once instead of for each participant. Thus, redundant encodings are recognized and eliminated resulting in less CPU usage.Type: GrantFiled: August 5, 2014Date of Patent: April 3, 2018Assignee: Genesys Telecommunications Laboratories, Inc.Inventors: Kevin O'Connor, Felix Immanuel Wyss

Patent number: 9813361Abstract: A method is disclosed for selectively turning off a switch arrangement for current distribution. A corresponding switch arrangement is also disclosed, including an upstream switch and a directly downstream switch connected in series, each switch being configured to check a current condition associated therewith. Connected between the upstream switch and the downstream switch is a communication link onto which the downstream switch puts a delay signal if its current condition is met and there is no fault present. Following reception of the delay signal, the upstream switch opens only after a delay time. In order to ensure turning off when there is a fault in the opening of a downstream switch even in the case of small overcurrents, when the current condition is met and the fault that prevents opening occurs, the downstream switch puts a fault report onto the communication link that trips the upstream switch.Type: GrantFiled: February 10, 2015Date of Patent: November 7, 2017Assignee: Siemens AktiengesellschaftInventor: Stefan Widmann

Patent number: 9801212Abstract: To solve a problem that unless all of a plurality of AICH signature states are correctly decoded, the contents of reception results cannot be recognized and the error rate of signature decoding will be high. In this embodiment, a base station uses, out of a signature combination, the signature of at least one predetermined position to indicate information containing a preamble reception result and uses the signature of a position other than the predetermined position to indicate a transmission profile information number of an uplink channel for notification to a user equipment. Thus, the error rate related to reception results can be reduced as compared with the case where a single signature combination is used to notify all pieces of information.Type: GrantFiled: April 8, 2016Date of Patent: October 24, 2017Assignee: NEC CORPORATIONInventors: Hiroaki Aminaka, Kojiro Hamabe, Jinsock Lee

Patent number: 9794118Abstract: The operating configuration at a node in a wireless communication network, at a neighboring node in the network, and/or at one or more wireless devices supported by the network, is updated based on determining timing information for an impending interruption of a radio link in the network to avoid erroneous operation during the impending interruption, which interruption is associated with an external system. The determination of interruption timing, which may be inferred, e.g., from detecting prior interruptions, or which may be known from information about the external system, and the modification of the operating configuration(s) permits the network to operate with greater stability, control, and accuracy during the interruptions than would be possible if the interruptions were simply treated as intermittent radio link failures.Type: GrantFiled: October 25, 2012Date of Patent: October 17, 2017Assignee: TELEFONAKTOEBOLAGET LM ERICSSON (PUBL)Inventors: Muhammad Kazmi, Joakim Axmon, Walter Müller
