NETWORK-LEVEL DEVICE PROXIMITY DETECTION

摘要

A technology for network-level device proximity detection is disclosed. In an example, core network (CN) device can include computer circuitry configured to: Store user equipment (UE) information; calculate proximity between two UEs; and assist the two UEs with direct device discovery based on the calculated proximity. The core network device can include a proximity services (ProSe) server, a gateway mobile location center (GMLC), an evolved serving mobile location center (E-SMLC), or a mobility management entity (MME).

主权项

1. A method for network-level device proximity detection at a mobility management entity (MME), comprising:
receiving, from a location estimation client, a location request to monitor a user equipment (UE); and sending a location update including UE rough location information to the location estimation client when the UE is monitored by the MME, wherein the UE rough location information includes a cell identifier (ID) or a registered tracking area ID for the cell or tracking area in which the UE is located.
