Patent number: 11706148Abstract: Datalink frames or networking packets contain protocol information in the header and optionally in the trailer of a frame or a packet. We are proposing a method in which part of or all of the protocol information corresponding to a frame or a packet is transmitted separately in another datalink frame. The “Separately Transmitted Protocol Information” is referred to as STPI. The STPI contains enough protocol information to identify the next hop node or port. STPI can be used avoid network congestion and improve link efficiency. Preferably, there will be one datalink frame or network packet corresponding to each STPI, containing the data and the rest of the protocol information and this frame/packet is referred to as DFoNP. The creation of STPI and DFoNP is done by the originator of the frame or packet such as an operating system.Type: GrantFiled: June 7, 2022Date of Patent: July 18, 2023Inventors: George Madathilparambil George, Susan George, Mammen Thomas

Patent number: 11665598Abstract: A method for batch handover authentication and key agreement oriented to a heterogeneous network generally includes the following steps: A, system establishment and participant registration: users participating in authentication register on the LTE-A network to obtain their respective identity information; B, access authentication: when a large number of users request access to the WLAN, the target network WLAN is discovered by using the ANDSF, and the leader sends a complete group authentication message to the AAA server of the WLAN to request identity authentication; if the authentication succeeds, the AAA server of the WLAN returns an identity authentication response; C, if the authentication fails, the continued execution of the protocol is terminated. The method effectively realizes batch authentication of users during handover from the LTE-A network to the WLAN, and thus has high authentication efficiency, small signaling overheads, and high security.Type: GrantFiled: June 28, 2021Date of Patent: May 30, 2023Assignee: Southwest Jiaotong UniversityInventors: Wenfang Zhang, Xiaomin Wang, Dan Chen

Patent number: 11665098Abstract: User traffic is processed in a virtualised network. First and second VNFs are initialised in the same network namespace as each other in user space in a host and have access to a shared memory region of the host. The first VNF processes user traffic and the second VNF provides a user plane service in relation to user traffic processed by the first VNF. The first VNF is used to establish a point-to-point, shared-memory interface between the first and second VNFs and is used to classify incoming user traffic. In response to the first VNF determining based on the classifying, that the incoming user traffic is to be subject to the user plane service, the first VNF is used to store the incoming user traffic in the shared memory region of the host to enable the second VNF to provide the user plane service in relation to the incoming trier traffic.Type: GrantFiled: April 28, 2021Date of Patent: May 30, 2023Assignee: METASWITCH NETWORKS LTD.Inventors: Martin Taylor, James Robert Andrew, Matthew Ian Ronald Williams

Patent number: 11653416Abstract: Embodiments of an access point (AP) configured for extremely high throughput (EHT) operation may be configured to operate as a triggering AP for a trigger-based (TB) peer-to-peer (P2P) communication between a triggered direct (TD) station (STA) and a TD peer STA. The AP may encode a Direct Link Announcement (DiL-A) frame to schedule the TD STA for a direct link transmission to the TD peer STA. The DiL-A frame may be encoded to include a Duration/ID field. The AP may set the Duration/ID field of the DiL-A frame to a remaining duration of a transmission opportunity (TXOP) when the TD peer STA is an EHT STA that supports TB P2P operation (e.g., to allow the TD peer STA to ignore the NAV set by the DiL-A frame). The AP may set the Duration/ID field of the DiL-A frame to a response time for the TD STA to respond to the DiL-A frame when the TD Peer STA is a legacy STA (e.g., to allow the TD peer STA to set its NAV based on the response time).Type: GrantFiled: October 26, 2020Date of Patent: May 16, 2023Assignee: Intel CorporationInventors: Dibakar Das, Laurent Cariou, Dmitry Akhmetov

Patent number: 11627025Abstract: Methods, systems, and devices for wireless communications are described. Autonomous transmissions between a user equipment (UE) and a base station may be configured that include at least one of a modulation and coding scheme (MCS) or resources for the transmissions. In some cases, a trigger may be detected that changes the MCS or resources to be used for the autonomous transmissions. The trigger may include the presence or absence of retransmissions or the value of a channel measurement falling below or exceeding a threshold value. Accordingly, the base station and UE may adjust the MCS or resources to be used for the autonomous transmissions based on detecting the trigger and then communicate using the adjusted MCS or resources. In some cases, the configuration for the autonomous transmissions may be signaled via a medium access control (MAC) control element (CE).Type: GrantFiled: August 26, 2019Date of Patent: April 11, 2023Assignee: QUALCOMM IncorporatedInventors: Vinay Joseph, Piyush Gupta, Junyi Li
