Abstract

A method for cell reselection control is disclosed, comprising: sending an instruction from a radio network to a user equipment (UE) in an idle mode to adjust an existing cell reselection parameter at a UE to a high value; subsequently instructing the UE to return the cell reselection parameter to its previous value, after a first predetermined interval; and subsequently sending a second instruction to the UE in an idle mode to adjust the cell reselection parameter at the UE to the high value, after a second predetermined periodic interval, causing the UE to reselect to a cell with superior signal even when the UE may be under good coverage attached to an existing macro cell, thereby offloading the macro cell.

First claim

The invention claimed is:

1. A method, comprising:
sending an instruction from a radio network to a user equipment (UE) in an idle mode to adjust an existing cell reselection parameter at a UE to a high value, wherein the radio network is one or more of a Global System for Mobile Communications (GSM), Enhanced Data Rates for GSM Evolution (EDGE), Universal Mobile Telecommunications System (UMTS), CDMA2000, Long Term Evolution (LTE), Long Term Evolution Advanced (LTE-Advanced), or 5G gNodeB radio network;
subsequently instructing the UE to return the cell reselection parameter to its previous value, after a first predetermined interval; and
subsequently sending a second instruction to the UE in an idle mode to adjust the cell reselection parameter at the UE to the high value, after a second predetermined periodic interval,
causing the UE to reselect to a cell with superior signal even when the UE is under good coverage attached to an existing macro cell, further comprising repeatedly raising the cell reselection parameter to a high value, in order to cause the UE to perform a neighboring cell search from idle mode and identity another cell to which to attach, thereby offloading the macro cell.

2. The method of claim 1 , wherein the cell reselection parameter is an Sintersearch threshold.

3. The method of claim 1 , wherein the cell reselection parameter is an Sintrasearch threshold.

4. The method of claim 1 , wherein the high value is a maximum permitted value.

5. The method of claim 1 , wherein the first predetermined interval and the second predetermined periodic interval are configured to cause the UE to perform a periodic neighboring cell search while having a 5% impact on projected UE battery life.

6. The method of claim 1 , wherein the first predetermined interval is 5 seconds and the second predetermined periodic interval is every 5 minutes.

7. The method of claim 1 , wherein the previous value is a cell reselection parameter value configured based on an assumption that significantly overlapping cell coverage is rare.

8. The method of claim 1 , wherein the cell with superior signal is a small cell configured to cover a small area that is a subset of the coverage area of the existing macro cell.

9. The method of claim 1 , wherein the radio network is a nodeB or eNodeB, and wherein the radio network is configured with the first predetermined interval and the second predetermined periodic interval by a coordinator node in an operator core network.

10. The method of claim 1 , wherein the cell reselection parameter is a SsearchRAT threshold.

11. The method of claim 1 , wherein the cell reselection parameter is an SrxlevServing parameter in a Long Term Evolution (LTE) radio access technology.

12. The method of claim 1 wherein a message is received from a core network using a first radio access technology and sent to a base station using a second radio access technology.
