Abstract: Presented herein are efficient techniques through which a Third Generation Partnership Project (3GPP) Access and Mobility Management Function (AMF) may retrieve information for a Mobility Management Entity (MME) to support graceful mobility for various inter-Radio Access Technology (inter-RAT) mobility scenarios. In one example, a method includes determining, by an AMF, an inter-RAT mobility event for a user equipment; identifying, by the AMF, an MME associated with the inter-RAT mobility event based, at least in part, on MME information contained in a network database; and transferring context information for the user equipment between the AMF and the MME. In one instance, the network database may be a Network Repository Function (NRF) for a 3GPP Fifth Generation mobile network and the MME information may be associated with an MME network function type stored in the NRF.

Abstract: The present disclosure is directed to managing industrial internet of things end points and includes one or more processors and one or more computer-readable non-transitory storage media coupled to the one or more processors and comprising instructions that, when executed by the one or more processors, cause one or more switches to perform operations comprising: identifying a first end point using a protocol associated with the first end point, determining a classification for the identified first end point based on one or more attributes of the first end point, identifying one or more related end points having the classification in common with the first end point, segmenting the first end point with the identified one or more related end points, and applying one or more policies to the segmented first end point and the one or more related end points.

Abstract: A network controller can register WAN edge routers and WAN optimizers distributed across a WAN. The controller can receive a request to establish a WAN optimized connection between first and second hosts. The controller can identify a first WAN optimizer to perform first services (e.g., de-duplication, compression, application acceleration, caching, etc.) for first traffic from the first host to the second host and first complementary services for second traffic from the second host to the first host, and a second WAN optimizer for the second traffic and second complementary services for the first traffic. The controller can establish the optimized connection comprising a first path including the first host, WAN optimizer, and router; a second path including the first router and a second router, and a third path including the second router, WAN optimizer, and host. The controller can route the first and second traffic through the optimized connection.

Abstract: Techniques are presented in which a new information element signaling priority of a management entity is included in a setup (e.g., S1-Setup) response or configuration update message sent by a management entity to a base station entity. The base station entity interprets this priority information along with the relative capacity information in an appropriate way to load-distribute the traffic/calls to highly preferable management entity instances (at a local site) when they are available, and switchover/failover to lower preference management entity instances (at a remote site) when there is a local site outage/failure or insufficient capacity in a geo-resilient pooled network.
