摘要

Methods and systems for End-to-End (E2E) User Equipment (UE) trajectory network automation are herein provided. According to one aspect, a network node for E2E UE trajectory network automation, such as a Network Data Analytics Function (NWDAF), receives, from a requesting entity, information identifying a future E2E UE trajectory, the E2E UE trajectory comprising a start location, an end location, and zero or more intermediate locations between the start location and the end location; calculates a E2E mobility trajectory prediction for the identified future E2E UE trajectory; and sends, to the requesting entity, the calculated E2E mobility trajectory prediction. The requesting entity may be a trusted entity or an untrusted entity, such as a Third Party Provider (3PP) outside of the trusted domain of the network. If the requesting entity selects a mobility trajectory, the network node sends mobility management and optimization information to a Radio Access Network node.

說(shuō)明書(shū)

FIGS. 4A through 4D and 5A and 5B illustrate exemplary call flows implementing methods for E2E UE trajectory network automation based on future UE location according to some embodiments of the present disclosure.

Mobility Trajectory Request from an Application Function

FIGS. 4A through 4D illustrate embodiments in which E2E mobility trajectory information is provided to the NWDAF from an untrusted source, i.e., from a 3PP AF, such as an online service provider, that is outside the PLMN domain.

FIG. 4A illustrates signals exchanged during an exemplary process for E2E UE trajectory network automation according to some embodiments of the present disclosure. In the embodiment illustrated in FIG. 4A, the process includes the following steps:

At step 400, an application function sends a request, such as a SendE2EMobilityTrajectoryRequest message, to a node that provides an interface into the core network, such as an NEF. At step 402, the NEF forwards that message to a PLMN node that performs analysis, such as a NWDAF or PCF. At step 404, the PLMN node performs an E2E mobility trajectory prediction. In some embodiments, the PLMN calculates the predicted UE experience on the requested E2E path or route. In some embodiments, the PLMN calculates the predicted UE experience and ETA on alternative mobility trajectories.
