Abstract:
A device obtains a list of a plurality of user devices from a first network device and receives a message intended for a destination user device from a second network device. The device obtains information indicating that the destination user device can receive messages that conform to a particular format from a third network device and converts the message to the particular format. The device determines a reachability of the destination user device based on the list of the plurality of user devices, after converting the message, and sends the message to the destination user device via the first network device based on the reachability. The device receives a delivery message from the destination user device and sends a notification message indicating successful delivery of the message to the second network device based on the delivery message.
Abstract:
A computer device may include a memory storing instructions and processor configured to execute the instructions to receive a request for a connection to a Packet Data Network gateway (PGW) from a User Equipment (UE) device; obtain subscription type information for the UE device; and determine that the UE device is associated with a Fifth Generation (5G) subscription based on the obtained subscription type information. The processor may be further configured to obtain a list of available PGWs from a 5G Network Repository Function (NRF), in response to determining that the UE device is associated with the 5G subscription; select a PGW from the obtained list of available PGWs based on a selection rule; and send a create session request for the UE device to the selected PGW.
Abstract:
Systems and methods provide reliable voice connections and highest possible data rates in New Radio dual-connectivity environments, given limitations of available spectrum. A system includes a first wireless station and a second wireless station. The first wireless station provides a shared spectrum of a first frequency band, the shared spectrum including a first spectrum for a first cellular wireless standard and a second spectrum for a second cellular wireless standard. The second wireless station is at least partially within a coverage area of the first wireless station and provides a third spectrum for the second cellular wireless standard. The third spectrum is a millimeter wave (mmWave) spectrum. The first wireless station broadcasts cell parameters barring an end device in an idle mode from camping on the second spectrum. The first wireless station or the second wireless station triggers the end device to swap to the second spectrum when a paging request for a voice call is received.
Abstract:
Systems and methods described herein enable improve handling of 5G-enabled devices in 4G core networks. The systems and methods described herein provide an enhanced HTTP-based interface between a SMF/PGW-C and a UDM to support interactions required to: (a) perform authorization of PDN access for non-3GPP networks, (b) provide an APN profile to the SMF+PGW-C for the PDN being setup, (c) update the SMF+PGW-C address in the UDM for the PDN being served by non-3GPP networks, and (d) provide operator-specific subscriber parameters from the UDM to the SMF+PGW-C for 3GPP and non-3GPP access.
Abstract:
A method, a device, and a non-transitory storage medium are described in which policy delivery is provided. A network device of a core network may receive a registration request message that includes a request for an end device policy. The network device may perform a registration procedure and a policy procedure pertaining to an end device. The network device determines when the registration and the policy procedures are completed. The network device transmits a registration response that includes an end device policy to an end device.
Abstract:
A computing device may include a memory configured to store instructions and a processor configured to execute the instructions to monitor a radio access technology type being used by a user equipment (UE) device to wirelessly communicate with a base station. The processor may be further configured to detect a change from a first radio access technology type to a second radio access technology type; determine that the second radio access technology type has been sustained for at least a particular time period; and report information identifying the change from the first radio access technology type to the second radio access technology type to a Policy and Charging Rules Function (PCRF) device.
Abstract:
A first device associated with an evolved packet core network receives a first update request from a second device associated with the evolved packet core network. The first update request is associated with a communication session previously provided between the first device and the second device, and the first update request is generated based on a voice/video request. The first device generates an update answer in response to the first update request, where the update answer includes a code requesting that the communication session be restored between the first device and the second device. The first device receives, based on the code, a second update request from the second device, where the second update request includes session information associated with the communication session. The first device restores, based on the session information, the communication session between the first device and the second device to create a restored communication session.

Abstract:
A first mobility management entity (MME) device receives an attachment request that includes information associated with a user device. The first MME device creates a context for the user device based on the information, stores the context, and creates an optimized context based on the context, wherein a size of the optimized context is smaller than a size of the context. The first MME device also identifies a second MME device that is a backup for the first MME device, and transmits the optimized context to the second MME device.
