Patent number: 10764430Abstract: A voice or video call is to be established between a caller and a callee based on a call flow that involves a call establishment request and a corresponding call acceptance response. A first call establishment request is sent to a called terminal (of the callee) that is unready to accept the call upon receiving this first call establishment request. Once the called terminal is ready to accept the call, instead of the call acceptance response, a reverse call establishment request for the call is received back from the called terminal. The reverse call establishment request is automatically accepted on behalf of the caller on condition that the reverse call establishment request was received back from the called terminal within a certain time limit. If so, the call is accepted by sending an instance of the call acceptance response to called terminal.Type: GrantFiled: January 8, 2016Date of Patent: September 1, 2020Assignee: Microsoft Technology Licensing, LLCInventors: Vincent Marc Oberle, Carl S.

Patent number: 10707955Abstract: A method performed by an intermediate unit of a distributed base station system of a wireless communication network. The distributed base station system has a first base unit and a second base unit connected to the intermediate unit. The intermediate unit is further connected to a first remote unit, which is further connected for distributing wireless signals to pieces of User Equipment (UEs). The intermediate unit receives, from the first base unit, first data and sends the first data over a point-to-point connection to the first remote unit for further distribution wirelessly over a radio channel to the UEs. In response to the reception of the first data, a first indication is sent to the second base unit that the radio channel is free. The second base unit can send second data that is then to be sent from the remote unit towards the UEs on the radio channel.Type: GrantFiled: November 27, 2015Date of Patent: July 7, 2020Assignee: Telefonaktiebolaget LM Ericsson (publ)Inventors: Elmar Trojer, Miguel Berg, Peter De Bruin, Bo Hagerman, Johan Söder

Patent number: 10693784Abstract: Techniques are described for supporting Fibre Channel over Ethernet (FCoE) link aggregation groups (LAGs) between a server and a data center switch in a data center. The techniques enable an access switch in the data center switch to assign class identifiers to each member link in an FCoE LAG between an FCoE node (Enode) of the server and the access switch. In this way, the access switch is able to redirect FCoE traffic from a Fibre Channel forwarder (FCF) of a storage area network (SAN) toward the Enode on the correct member link of the FCoE LAG. The techniques also enable scaling of FCoE initialization protocol (FIP) and FCoE sessions by installing FIP snooping filters that use on a source media access control (MAC) address hit determination in ingress filter processors (IFPs) of the access switch to avoid session limitations of virtual local area network (VLAN) filter processors (VFPs).Type: GrantFiled: April 9, 2018Date of Patent: June 23, 2020Assignee: Juniper Networks, Inc.Inventors: Nirmal Kumar Ramalingam, Amit Shukla, Srilakshmi Adusumalli

Patent number: 10686642Abstract: The present disclosure relates to adaptive modulation and coding scheme selection and signaling in a communication system. In particular, a modulation and coding scheme to be used for transmission of a data is selected from a set of predetermined modulation and coding schemes. The predetermination of the set is performed by selecting the set from a plurality of predefined sets. The sets have the same size, so that a modulation and coding selection indicator signaled to select the modulation and coding scheme may be advantageously applied to any of the selected sets. Moreover, a second set includes schemes with a modulation not covered by the schemes of a first set, and which is of a higher order than any modulation in the first set.Type: GrantFiled: March 14, 2019Date of Patent: June 16, 2020Assignee: Sun Patent TrustInventors: Michael Einhaus, Alexander Golitschek Edler von Elbwart, Joachim Loehr, Masayuki Hoshino
