Filed:

Jun 2, 2021

Appl. No.:

17/336857

Inventors:

- San Jose CA, US
Ian McDowell Campbell - Littleton CO, US
Ravi Shankar Mantha - Bangalore, IN

International Classification:

H04W 88/16
H04W 28/02
H04W 76/16
H04W 76/12

Abstract:

The present technology is directed to establishing a connection between a client device within a 2G or 3G network and 5G core through an interworking function. The present technology can perform establishing a Gn-4G interworking function (IWF) between a client access network and a packet anchor network and performing one or more network functions through the Gn-4G IWF in providing a client of the client access network access to network services through the packet anchor network. The one or more network functions appear as one or more Gateway GPRS Support Node (GGSN) functions from the client access network (e.g., 2G or 3G network). The one or more network functions concurrently appear as one or more S4 Serving GPRS Support Node (SGSN) functions from the packet anchor network (e.g., 4G or 5G network).

Abstract:

A network slice controller obtains health information of an active network slice provided by a first vendor and health information of a set of backup network slices provided by a second vendor. The network slice controller evaluates, using a set of policies corresponding to management of the active network slice, the health information of the active network slice to determine whether the active network slice has failed. As a result of the failure of the active network slice, the network slice controller identifies one or more backup network slices of the set of backup network slices to serve as new active network slices. The network slice controller activates these one or more backup network slices to serve as the new active network slices for the network.

Appl. No.:

17/004525

Inventors:

- San Jose CA, US
Ian McDowell Campbell - Littleton CO, US
Swapna Anandan - Fremont CA, US

International Classification:

H04L 29/08

H04L 12/24
H04L 29/12
H04W 4/50

Abstract:

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.

Abstract:

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.

Abstract:

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.
