In one example, a method includes detecting that a user equipment device has moved to a location in a telecommunications network in which a first network route is available, where the first network route has a higher priority than a second network route with which an application executing on the user equipment device has established a current protocol data unit session, determining that the application should switch the current protocol data unit session to the first network route, and supporting the application in switching the current protocol data unit session from the second network route to the first network route.

Supporting movement of 5G protocol data unit sessions to higher priority network routes

The described technology is generally directed towards network slice pre-configuration for cellular communication systems, including 5G and subsequent generation cellular communication systems. Network equipment can be preconfigured to identify whether a network slice identifier included in a network communication belongs to a group of network slice identifiers. If so, the network equipment can process the network communication either according to a network slice rule that corresponds specifically to the network slice identifier, or according to a default group network slice rule for the group to which the network slice identifier belongs. Different groups of network slice identifiers can be associated with different sets of group network slice rules which can be arranged to reduce the work of setting up network slice identifiers in various network slicing scenarios.

5G network slice pre-configuration

Aspects of the subject disclosure may include, for example, a device including a processing system including a processor; and a memory that stores executable instructions that, when executed by the processing system, facilitate performance of operations of receiving a query for 5G Session Management Functions (SMFs) to handle a connection request, wherein the query includes a slice ID and data network name; determining a list of SMFs that each have a blockchain ID immutably recorded on a blockchain, wherein the blockchain ID is authorized to provide service to the slice ID; and sending, responsive to the query, the list of SMFs. Other embodiments are disclosed.

System and method of securing allocation of network functions for session slices

A system can facilitate assigning guaranteed bitrate (GBR) admission control thresholds in a network with multiple network slices serving multiple GBR services. Thus, each network slice can optionally have its own dedicated GBR admission. For example, based on a requested service, the system can compare a received quality indicator to a threshold value to determine if a bearer shall be admitted in accordance with dedicated GBR admission control region within its slice. If the slice does not have its own GBR admission control region or if its threshold is reached, the system can compare the received quality indicator to another threshold value to determine if the bearer shall be admitted in accordance with a common GBR admission control region.

Flexible configuration of guaranteed bitrate admission control for 5G or other next generation network

A system can facilitate assigning guaranteed bitrate (GBR) admission control thresholds in a network with multiple network slices serving multiple GBR services. Thus, each network slice can optionally have its own dedicated GBR admission. For example, based on a requested service, the system can compare a received quality indicator to a threshold value to determine if a bearer shall be admitted in accordance with dedicated GBR admission control region within its slice. If the slice does not have its own GBR admission control region or if its threshold is reached the system can compare the received quality indicator to another threshold value to determine if the bearer shall be admitted in accordance with a common GBR admission control region.

The described technology is generally directed towards enabling user equipment to perform route selection across multiple mobile communication technologies. User equipment route selection allows specifying, by the user equipment, information which affects the way the user equipment's network communications are handled by a communication network. User equipment route selection across multiple mobile communication technologies enables certain route selection capabilities whether the user equipment is connected to a 5G Core network mobile communication technology, a 5G Option 3&#xd7; network mobile communication technology, or a LTE network mobile communication technology.

User equipment route selection across multiple mobile communication technologies

A device performs registering with a first access network to generate a first registration, detecting a triggering event, and registering with a second access network to generate a second registration while maintaining the first registration with the first access network.
