Abstract  Abstract

Embodiments of apparatus packages computer-implemented methods systems devices and computer-readable media (transitory and non-transitory) are described herein for ascertaining e.g. by a traffic detection function (TDF) that a first user equipment (UE) and a second UE are potentially sufficiently proximate to each other to wirelessly exchange data directly. In various embodiments an evolved serving mobile location center (E-SMLC) may be instructed e.g. by the TDF to obtain location change data associated with the first and second UEs. In various embodiments a determination may be made e.g. by the TDF based on the location change data whether the first and second UEs are sufficiently proximate to exchange data directly and whether the first and second UEs are likely to remain proximate for at least a predetermined time interval. In various embodiments the first and second UEs may be caused to commence device-to-device (D2D) communication based on the determination.
