Method and apparatus for proximity discovery for device-to-device communication

摘要

A method, network node, and user equipments for providing parameters to a first user equipment served by the network element, the parameters describing at least a second user equipment for the purpose of the first user equipment initiating a device to device proximity discovery service with the second user equipment, the method collecting information for user equipments desiring device to device proximity discovery; creating a candidate user equipment list for a candidate tier based on the collected information at the network element, wherein each candidate tier comprises one or more thresholds based on timing advance values in use at the first or the at least the second user equipment; and providing the parameters describing at least a second user equipment to the first user equipment.

1. A method at a network element for providing parameters to a first user equipment served by the network element, the parameters describing at least a second user equipment for the purpose of the first user equipment initiating a device to device proximity discovery service with the second user equipment, the method comprising:
collecting information for user equipments desiring device to device proximity discovery; creating a candidate user equipment list for a candidate tier based on the collected information at the network element and one or more thresholds of the candidate tier, wherein the one or more thresholds are based on timing advance values in use at the first or the at least the second user equipment; and providing the parameters describing at least a second user equipment to the first user equipment.
