Abstract: The described technology is generally directed towards contextual network function selection and transfer. Techniques disclosed herein can be implemented at core network access management functions (AMFs). An AMF can obtain user equipment context information via a gNodeB (gNB). Rather than causing a local default session management function (SMF) and user plane management function (UPF) to process user equipment communications, the AMF can use a mapping function to identify, based on the user equipment context information, a proximal SMF and corresponding UPF which have a nearer proximity to the user equipment. The AMF can facilitate selection of the proximal SMF and UPF for the user equipment, and the AMF can transfer the user equipment context information to a proximal AMF that is better situated to serve the proximal SMF and UPF. By facilitating transfer to the proximal SMF and UPF, communication latency experienced by the user equipment can be reduced.

Abstract: The described technology is generally directed towards transferring coverage enhancement information from a terminal adapter to a terminal equipment. In one aspect, a terminal equipment can send a communication command to a terminal adapter requesting return of coverage enhancement information, and receive the coverage enhancement information from the terminal adapter. The terminal equipment provides access to the coverage enhancement information to a program running on the terminal equipment. In another aspect, a terminal adapter activates coverage enhancement information reporting, and sends coverage enhancement information to a terminal equipment. The terminal adapter monitors for a coverage enhancement state change.
