Abstract
Embodiments of the claimed subject matter provide embodiments of a method and apparatus for dynamically modifying cell reselection parameters and/or handover parameters. One embodiment of the method includes providing a request for a cell reselection parameter or handover parameter in response to a small cell determining that a number of cell reselections or a number of handovers between the small cell and at least one macrocell exceeds at least one threshold. In this embodiment, the cell reselection parameter or handover parameter is stored in the small cell.
Claims31
A method, comprising:
- determining, at a small cell, at least one of a number of cell reselections for idle access terminals and a number of handovers for active access terminals,
- providing, from the small cell, a request for at least one cell reselection parameter or handover parameter in response to the at least one of the number of cell reselections or the number of handovers between the small cell and at least one macrocell exceeding at least one threshold;
- and
- storing said at least one cell reselection parameter or handover parameter in the small cell.
1 more element
A method, comprising:
- receiving, at a first server from a small cell, a first request for at least one cell reselection parameter or handover parameter in response to the small cell determining that at least one of a number of cell reselections by at least one idle access terminal exceeds at least one cell reselection threshold or a number of handovers between the small cell and at least one macrocell by at least one active access terminal exceeds at least one handover threshold;
- and
- providing, from the first server, said at least one cell reselection parameter or handover parameter to the small cell.
A method, comprising:
- receiving, at a second server from a first server, a request for at least one cell reselection parameter or handover parameter in response to a small cell determining that at least one of a number of cell reselections by at least one idle access terminal exceeds at least one cell reselection threshold or a number of handovers between the small cell and at least one macrocell by at least one active access terminal exceeds at least one handover threshold;
- and
- providing, from the second server to the first server, said at least one cell reselection parameter or handover parameter for transmission from the first server to the small cell.
A small cell, comprising:
- at least one counter for counting at least one of a number of cell reselections or a number of handovers between the small cell and at least one macrocell, wherein said at least one counter comprises a plurality of counters for counting cell reselections of idle access terminals and handovers of active access terminals;
- and
- a comparator for determining whether said at least one of the number of cell reselections or the number of handovers exceeds at least one threshold.
A management server, comprising:
- a database for storing information indicating at least one of a number of cell reselections or a number of handovers between a small cell and at least one macrocell, wherein said information is received from the small cell in response to said at least one of the number of cell reselections by at least one idle access terminal exceeding at least one cell reselection threshold or the number of handovers between the small cell and at least one macrocell by at least one active access terminal exceeding at least one handover threshold;
- and
- a processing element configured to generate a request to modify at least one cell reselection parameter or handover parameter used by the small cell, wherein said request is generated based on said information stored in the database.
A network server, comprising:
- a processing element configured to generate at least one cell reselection parameter or handover parameter in response to a small cell determining that at least one of a number of cell reselections by at least one idle access terminal exceeds at least one cell reselection threshold or a number of handovers between the small cell and at least one macrocell by at least one active access terminal exceeds at least one handover threshold.
