Method of releasing resource reservation in network
The present disclosure provides methods for releasing a reserved resource in a network. An operation method performed in a first communication node of a vehicle network includes generating a first frame including identification information of a stream transmitted through a reserved resource and a first indicator instructing to release the reserved resource; and transmitting the first frame to a second communication node.
SYSTEMS AND METHODS FOR PSEUDO RANDOM BEACON SIGNAL SCHEDULING AND DATA SCHEDULING TO IMPROVE NETWORK CONDITIONS
Systems and methods for pseudo random beacon signal scheduling and data scheduling to improve network conditions within a wireless network are disclosed herein. In one embodiment, a system for providing a wireless asymmetric network, comprises a hub having one or more processing units and at least one antenna for transmitting and receiving radio frequency (RF) communications in the wireless asymmetric network. A plurality of sensor nodes each have a wireless device with a transmitter and a receiver to enable bi-directional RF communications with the hub in the wireless asymmetric network. The system determines dynamic beacon frequency control with a variable delay duration for starting at least one superframe of the hub.
REDIRECTING TRAFFIC FROM MOBILE DEVICE TO INITIAL SLICE SELECTOR FOR CONNECTION
Some embodiments provide a method for a first network slice selector that selects network slices for connections from endpoint devices located within a first geographic range. The method selects a network slice for a connection between a mobile endpoint device and a network domain that originates when the mobile endpoint device is located within the first geographic range. The method stores state that maps the connection to the selected network slice. The method forwards data traffic belonging to the connection from the mobile endpoint device onto the selected network slice using the stored state. After the mobile endpoint device moves from the first geographic range to a second geographic range, the method receives data traffic belonging to the connection from a second network slice selector that selects network slices for connections from endpoint devices within the second geographic range and forwards said received data traffic onto the selected network slice.
Device-assisted services for protecting network capacity
Device Assisted Services (DAS) for protecting network capacity is provided. In some embodiments, DAS for protecting network capacity includes monitoring a network service usage activity of the communications device in network communication; classifying the network service usage activity for differential network access control for protecting network capacity; and associating the network service usage activity with a network service usage control policy based on a classification of the network service usage activity to facilitate differential network access control for protecting network capacity.
METHOD AND SYSTEM FOR TRAFFIC MANAGEMENT USING A UNIFIED NETWORK BARRING MECHANISM
A method, a device, and a non-transitory storage medium are provided to store traffic management data that indicates different levels of congestion that are each correlated to a different category of application of an end device, a type of congestion mechanism including at least one of access class barring, enhanced access class barring, service specific access control, application specific congestion control for data communication, or unattended and background data traffic, and barring parameters; receive a request for wireless service; obtain a level of congestion; determine that the request cannot be granted based on the level of congestion; select one of the levels of congestion based on the level of congestion; generate a first barring message based on the type of congestion mechanism, barring parameters, and category of application correlated to the one of the levels of congestion; and transmit the first barring message to the end devices.
Method to achieve bounded buffer sizes and quality of service guarantees in the internet network
Methods to achieve bounded router buffer sizes and Quality of Service guarantees for traffic flows in a packet-switched network are described. The network can be an Internet Protocol (IP) network, a Differentiated Services network, an MPLS network, wireless mesh network or an optical network. The routers can use input queueing, possibly in combination with crosspoint queueing and/or output queueing. Routers may schedule QoS-enabled traffic flows to ensure a bounded normalized service lead/lag. Each QoS-enabled traffic flow will buffer O(K) packets per router, where K is an integer bound on the normalized service lead/lag. Three flow-scheduling methods are analysed. Non-work-conserving flow-scheduling methods can guarantee a bound on the normalized service lead/lag, while work-conserving flow-scheduling methods typically cannot guarantee the same small bound. The amount of buffering required in a router can be reduced significantly, the network links can operate near peak capacity, and strict QoS guarantees can be achieved.
AF initiated Always-on PDU Session
A policy control function (PCF) receives a first message from an application function (AF). The first message comprises: an always-on PDU session requested indication; an identity of a wireless device; and application service information. The PCF maps, based on the first message, the application service information to an always-on PDU Session for the wireless device. The PCF sends to a session management function (SMF), at least one policy and charging rule for the always-on PDU Session.
Restrict Services and Policy Control for Always-on PDU Session
A wireless device sends a PDU session establishment request message to an access and mobility management function (AMF). The PDU session establishment request message requests establishment of a packet data unit (PDU) session for an always-on PDU session. The wireless device receives a first message from the AMF. The first message indicates at least one service associated with the always-on PDU session. The wireless device sends at least one packet of an at least one allowed service of the at least one service via the always-on PDU session.
Set buffer state instruction
Input/output (I/O) operation requests from pageable storage mode guests are interpreted without host intervention. In a pageable mode virtual environment, requests issued by pageable storage mode guests are processed by one or more processors of the environment absent intervention from one or more hosts of the environment. Processing of the requests includes manipulating, by at least one processor on behalf of the guests, buffer state information stored in host storage. The manipulating is performed via instructions initiated by the guests and processed by one or more of the processors.
METHOD AND APPARATUS FOR RETRANSMISSION
Aspects of the disclosure provide an apparatus for wireless communication. The apparatus includes a transceiver and a processing circuit. The transceiver is configured to transmit and receive wireless signals. The processing circuit is configured to detect an error of a previous scheduled transmission of data units from the apparatus to another apparatus. The other apparatus provides scheduled resources for transmission between the two apparatuses. Further, the processing circuit is configured to determine resources that are scheduled by the other apparatus for the apparatus to perform retransmission, and provide one or more of the data units in the previous scheduled transmission to the transceiver for retransmission using the scheduled resources.
