Mobility analytics exchange between network entities
Aspects presented herein may improve the efficiency, accuracy, and/or latency of a UE positioning procedure by enabling mobility analytics associated with a UE or a set of UEs to be exchanged between a location server and an NWDAF, either directly or via another network entity. In one aspect, a first network entity transmits a request for mobility data associated with a set of UEs, where the request for the mobility data is transmitted for a second network entity associated with mobility data analytics. The first network entity receives, based on the request, an indication of the mobility data associated with the set of UEs. The first network performs at least one location function for at least one UE in the set of UEs based on the indication of the mobility data.
