Abstract

A base station of a communications network includes a transceiver circuit configured to transmit signals in a first Radio Access Node (RAN) and signals in a second RAN, and a controller configured to determine if signals in the second RAN should be stopped based on a load of the first RAN.

First claim

What is claimed is:

1. A base station of a communications network, the base station comprising:
a transceiver circuit configured to transmit signals in a first cell and signals in a second cell; and
a controller configured to:
determine if signals in the second cell should be stopped based on a load of the first cell; and
update information of a neighbor cell when the signals in the second cell is stopped, and

wherein the information of the neighbor cell includes at least one of frequency and tracking area code used in the neighbor cell.

2. The base station of claim 1 , wherein the controller is further configured to stop signals in the second cell.

3. The base station of claim 1 , wherein the first cell includes a 3G cell and the second cell includes a Long Term Evolution (LTE) cell.

4. The base station of claim 1 , wherein the first cell includes a Long Term Evolution (LTE) cell and the second cell includes a 3G cell.

5. A communications method in a base station of a communications network, the communications method comprising:
transmitting, by the base station, signals in a first cell and signals in a second cell; and
determining, by the base station, if signals in the second should be stopped based on a bad of the first cell;
updating, by the base station, information of a neighbor cell when the signals in the second cell is stopped,
wherein the information of the neighbor cell includes at least one of frequency and tracking area code used in the neighbor cell.

6. The communications method of claim 5 , wherein the method further comprises stopping, by the base station, signals in the second cell.

7. The communications method of claim 5 , wherein the first cell includes a 3G cell and the second cell includes a Long Term Evolution (LTE) cell.

8. The communications method of claim 5 , wherein the first cell includes a Long Term Evolution (LTE) cell and the second cell includes a 3G cell.
