Method and telecommunications infrastructure for activating an inactive cell

摘要

The invention relates to a method for activating at least one inactive cell in a wireless telecommunications infrastructure. The telecommunications infrastructure comprises an active cell containing a plurality of terminals. A presence signal is transmitted in the at least one inactive cell. The plurality of terminals in the active cell detect the presence signal(s) of the one or more inactive cells to gather information from the inactive cell. The information is reported to and received at the telecommunications infrastructure. The information received from the plurality of terminals is processed in a processing system of the telecommunications infrastructure to provide a processing result. The inactive cell is activated when the processing result fulfills at least one activation condition such that at least one of the plurality of terminals is within a coverage area of the activated cell.

主权项

1. A terminal configured for operating in a wireless access telecommunication infrastructure comprising an active base station and at least one inactive cell, wherein the terminal comprises:
a processor for executing instructions that cause the terminal to carry out operations including: receiving in a transmission from the active base station measurement parameters and/or reporting parameters, wherein the received measurement parameters and/or reporting parameters trigger the terminal to obtain information regarding a presence signal from the at least one inactive base station; receiving the presence signal transmitted from the at least one inactive base station; obtaining a measurement report regarding the presence signal transmitted from the inactive base station and; providing the measurement report to the telecommunications infrastructure via the active base station, wherein the operations further include: receiving a reporting identifier transmitted from the inactive base station, the received reporting identifier indicating that the inactive base station is in a probing period; recognizing the reporting identifier; and including the reporting identifier in the measurement report, the included reporting identifier being an indication to the telecommunications infrastructure that the measurement report was not obtained as part of a handover to the inactive base station.
