摘要： Methods and apparatus for use in establishing a group session in a mobile network for subscribers associated with a group are described. In one illustrative example, an access and mobility management function (AMF) entity receives, from a user equipment (UE), a request for registration which includes network slice selection assistance information (NSSAI). The NSSAI includes a group identifier associated with a group of subscribers. The AMF entity sends, to a unified data management (UDM) entity, a request for subscriber data which includes the group identifier. The AMF entity receives, from the UDM, a response to the request for subscriber data which includes a plurality of subscriber identifiers corresponding to the subscribers of the group. For a group session, the AMF entity creates a context associated with the group identifier and stores the context locally.

摘要： In one illustrated example, automated or semi-automated system operations for Massive IoT (MIoT) deployment may involve the automatic assignment of external IDs, subscriber IDs (e.g. IMSIs), and mobile network IDs (e.g. MSISDNs) to IoT devices of a group, followed by the provisioning of assigned identities at the relevant network nodes and the IoT devices themselves. The process may continue seamlessly with network slice orchestration for the creation of a network slice instance (NSI) and the provisioning of its associated Network Slice Selection Assistance Information (NSSAI) and NSI ID at the relevant network nodes. Network Slice Selection Policies (NSSP) may be derived and sent to a policy function and subsequently to IoT devices of the group. Signaling efficiency may be achieved by performing operations on a group basis.

摘要： A method is provided in one example embodiment and may include receiving load information for a plurality of cells of a Radio Access Network (RAN); determining, for each of a plurality of user equipment (UE) in each cell, identification information for each UE and an Access Point Name (APN) to which each UE is connected; identifying, from a plurality of policy servers, each policy server that serves each APN to which each UE in each cell of the plurality of cells is connected; and sending, to each of a particular policy server, congestion information comprising: an identity for each cell having UE that are connected to each APN served by the particular policy server; the corresponding congestion level for each of the cells; and a per-cell UE list identifying each of a plurality of UE connected to each of APNs served by the particular policy server.

摘要： Systems, methods, and computer-readable media for managing service calls over a network may include a signal routing engine with a maintained forwarding table for various network functions and micro-services in a services back end for the network. The signal routing engine can include a call conversion service for converting REST API calls to an internal network call protocol for increasing network function processing speeds, decreasing bandwidth usage, and improving network responsiveness and manageability.

摘要： Disclosed is a method that includes periodically observing packets in a user plane according to at least one key performance indicator in a configuration file to yield an observation, wherein the observation represents a closed-loop demand of resources within the user plane. The method includes adjusting, via a scheduler in the user plane and based on the observation, a binding of cores to work items. The binding between cores and work items is dynamic and changeable to improve performance. The at least one key performance indicator can include one or more of a CPU utilization, latency and packet drops. The workload allocations can include work items that are individually scheduleable functions that operate on a queue of packets within the user plane.

摘要： An example method is provided in one example embodiment and may include receiving a packet for a subscriber at a gateway, wherein the gateway includes a local policy anchor for interfacing with one or more policy servers and one or more classifiers for interfacing with one or more service chains, each service chain including one or more services accessible by the gateway; determining a service chain to receive the subscriber's packet; appending the subscriber's packet with a header, wherein the header includes, at least in part, identification information for the subscriber and an Internet Protocol (IP) address for the local policy anchor; and injecting the packet including the header into the service chain determined for the subscriber.
