Abstract: Described are examples for providing end-to-end intent definition of network functions for network slice management. Intents are defined for each level of network constituent including slices, slice subnets, and management functions. A system of intent based network slice management includes a network slice management function (NSMF) configured to receive a service profile from a communication service management function (CSMF) and derive an intent for each desired network slice subnet for a network slice subnet management function (NSSMF). The NSSMF is configured to derive requirements for a plurality of network functions (NFs) and provide an intent defining the requirements of a respective NF to a network function management function (NFMF). The NFMF is configured to receive the intent for the respective NF via an intent-based interface for management of NFs and derive a network resource model (NRM) for the respective NF based on the intent.

Abstract: A method of data communication includes receiving, by a first wireless access gateway (WAG), at least a first data packet corresponding to a first data flow transmitted from user equipment (UE) and receiving, by a second WAG, at least a second data packet transmitted from the UE. In response to receiving the second data packet, the second WAG determines an identity of the first WAG, and in response to determining the identity of the first WAG, the method includes establishing a tunnel connection between the first WAG and the second WAG. After establishing the tunnel connection, the method includes receiving by the second WAG at least a third data packet corresponding to the first data flow transmitted from the UE, and the second WAG transmits to the first WAG, via the tunnel connection, the third data packet.

Abstract: Described are examples for providing intent based network slice management using a management data analytics function (MDAF) to predict deficiencies. A network management system receives an intent for a network slice constituent. The network management system configures computing resources for the network slice constituent to satisfy the intent based on expected performance of the computing resources. The network management system receives feedback with respect to actual performance of the network slice constituent. The network management system determines, based on analysis of the feedback by a management data analytics function (MDAF), a predicted deficiency of the network slice constituent not being able to satisfy the intent. The network management system modifies the configuration of the computing resources based on the feedback and the predicted deficiency to satisfy the intent.

Abstract: A network function is implemented using cloud native architecture. The network function utilizes one or more loosely coupled and independently deployable microservice instances to perform services. To retain state between independent transactions, a microservice instance takes a soft lock on state data in an external database. The soft lock makes the state data unavailable except to the microservice instance. After the microservice instance completes the transaction, the microservice instance clears the lock so that the state data is available for use by other microservices.

Abstract: Techniques for distributed charging in digital telecommunications networks are disclosed. In one particular embodiment, the techniques may be realized as a method that includes provisioning a data path that carries a plurality of network flows, receiving a shared usage quota associated with the plurality of network flows, and allocating the shared usage quota among the plurality of network flows. For each network flow among the plurality of network flows, the method includes providing the data path with data indicative of an amount of the shared usage quota allocated to the network flow, configuring the data path to collect metering data associated with the network flow, and configuring the data path to enforce the shared usage quota based on the metering data associated with the network flow and the amount of the shared usage quota allocated to the network flow.

Abstract: Embodiments disclosed herein relate to systems and methods for separately managing control and data plan contexts for a secure connection during a standby node switchover scenario. Primary and standby nodes for a secure connection can both maintain a data plane context for a secure connection such as IPSec. In the event that the primary node becomes inactive, the standby node can immediately begin processing data plane traffic using the data plane context for the secure connection maintained at the standby node. Control plane information necessary for programming and activating a control plane context can be stored until needed. During a switchover, the standby node can retrieve the control plane information and activate the control plane context after it has begun processing the data plane traffic.

Abstract: Systems and methods for adaptively adjusting a transaction rate at a mobile network node. A first mobile network client node receives configuration parameters including an initial transaction rate, a step up rate, a step down rate, a minimum rate, a maximum rate, an evaluation time period, a step up response time threshold, a step down response time threshold, a step up threshold percentage of responses, and a step down threshold percentage of responses. Responses associated with communications with the server node are received during a first time period associated with the evaluation time period. A percentage of the received responses being less than the step up response time threshold and a percentage of the received responses being greater than the step down response time threshold are determined. An initial transaction rate is increased by the step up rate or decreased by the step down rate based on the determined percentages.

The method includes, when a diversion is to be used, selecting a secondary airport to which the aircraft is to be diverted, the secondary airport being selected based on a secondary expected operating capability. The method includes scheduling the diversion for the aircraft to the secondary airport.

Abstract: The present invention provides systems and methods which create an infrastructure/transport Pseudowire (PW) a priori between two Provider Edge (PE) devices. Accordingly, other PWs can be mapped to this transport PW. In an exemplary application, the transport PW (which is a MS-PW by itself) can start and end between two Switching Provider Edge (S-PE) devices and span across multiple S-PEs in between. In another exemplary application, the transport PW terminates between two Terminating Provider Edge (T-PE) devices spanning across all S-PEs in between. In a further exemplary application, the transport PW can start at a S-PE or T-PE and terminate at a T-PE or S-PE, respectively. The placement of the endpoints of the transport PW (on two PEs) determines the number of intervening S-PEs that benefit from this application.
