Patent number: 12177772Abstract: Apparatus and methods for interworking a user device in one or more wireless networks. In one embodiment, the apparatus and methods provide enhanced wireless services which enable operation of a given user device (e.g., a mobile 3GPP-compliant UE) within two or more mobile networks (e.g., PLMNs), such as a macro network and micro network. In one implementation, the UE contains multiple SIM cards to enable connection to different networks simultaneously. Accordingly, the UE can roam between two different networks seamlessly, regardless of whether the operators of each are independent or the same operator. Enhanced network capability as described herein advantageously allows for interworking between the macro and micro (e.g., small-cell) layers of the system without complicated network configuration requirements between the two operating networks as required under the prior art.Type: GrantFiled: January 23, 2023Date of Patent: December 24, 2024Assignee: CHARTER COMMUNICATIONS OPERATING, LLCInventors: Curt Wong, Yildirim Sahin, Maulik Vaidya

Patent number: 12177943Abstract: In one embodiment, a gateway to a Layer-3 network forms a first Layer-2 tunnel between the gateway and a first wireless access point (AP) that communicates wirelessly with a first mobile node of a mobile system (MS) via a first wireless connection. The gateway generates a mapping that associates an onboard device of the MS with the first AP and an identifier for the MS, based on traffic conveyed via the first Layer-2 tunnel and associated with the onboard device, the traffic comprising a header that indicates the identifier for the MS. The gateway receives, from a second AP, an indication that the MS is roaming from the first wireless connection to a second wireless connection, the indication including the identifier for the MS. The gateway updates the mapping to associate the onboard device of the MS with a second AP, based on the indication that the MS is roaming.Type: GrantFiled: December 4, 2020Date of Patent: December 24, 2024Assignee: Cisco Technology, Inc.Inventors: Vincent Cuissard, Domenico Ficara, Alessandro Erta, Luca Bisti, Kasi Nalamalapu, Sudhir Kumar Jain, Salvatore Valenza, Arun Khanna, Stefano Ferrari, Loris Gazzarrini

Patent number: 12170615Abstract: In order to route a data packet in a communication network, a network element implements a traditional routing process including taking a routing decision as a function of the destination of the data packet according to route learning in the communication network. The routing element reviews the routing decision taken by the traditional routing process via an internetwork policy-based routing function selected from among a plurality of candidate internetwork policy-based routing functions, each candidate internetwork policy-based routing function being assigned to an egress interface of the network element and vice versa. The selected internetwork policy-based routing function is that which is assigned to the egress interface selected by the traditional routing process for routing the data packet in the communication network.Type: GrantFiled: December 19, 2019Date of Patent: December 17, 2024Assignee: Airbus Defence and Space SASInventor: Claude Poletti

Patent number: 12170927Abstract: The embodiments of the present disclosure provide methods and apparatuses for control of Quality of Service (QoS). A method applied in a base station for control of QoS includes: receiving a Core Network (CN) flow identifier and information on a corresponding QoS parameter of a Packet Data Network (PDN) connection as transmitted from a CN control network element and creating a mapping relation between the CN flow identifier and the corresponding QoS parameter; and utilizing, after determining based on the received information on the QoS parameter of the PDN connection that a radio bearer satisfying a requirement of the QoS parameter exists between a user terminal and the base station, the existing radio bearer satisfying the requirement of the QoS parameter, creating a mapping relation between the existing radio bearer and the CN flow identifier of the PDN connection and transmitting information on the mapping relation to the user terminal.Type: GrantFiled: November 14, 2022Date of Patent: December 17, 2024Assignee: ZTE CorporationInventors: Jinguo Zhu, Xiaoyun Zhou, Shuang Liang, He Huang

Patent number: 12167282Abstract: A communication device, method and computer program product reduce time to connect a communication session. The communication device registers for cellular communication service using a first radio access technology (RAT) or sub-RAT with a first node. The communication device determines whether a connection for a selected communication service is predicted to be available from the first node. The communication device determines whether a request for the selected communication service is predicted to occur. In response to determining that the connection for the selected communication service is unavailable from the first node and the request for the selected communication service is predicted to occur, the communication device identifies a second node that supports communication using a second RAT/sub-RAT. The communication devices triggers registration fallback from the first node to the second node.Type: GrantFiled: January 27, 2022Date of Patent: December 10, 2024Assignee: Motorola Mobility LLCInventor: Daniel C Chisu

Patent number: 12167499Abstract: Methods, systems, and storage media described herein may have the complexity to support simultaneous communications (e.g., transmission/reception to/from) with two or more cells. Therefore, before configuring a handover, the network needs to know if these methods, systems, and storage media can support simultaneous communication with multiple cells or not. Among other things, these methods, systems, and storage media can reduce the interruption time during handovers for when these methods, systems, and storage media are capable of such simultaneous communication.Type: GrantFiled: October 28, 2019Date of Patent: December 10, 2024Assignee: APPLE INC.Inventors: Qiming Li, Hua Li, Rui Huang, Jie Cui, Yang Tang
