Terminal handover method, controller, terminal, base station, and system
First Claim
1. A method, comprising:
- determining, by a controller, that a terminal, which has been located in a coverage area of a first base station, moves into a coverage area of a second base station;
sending, by the controller, to the second base station, a radio identifier of the terminal, and a control channel resource that is configured by the controller for the terminal, and that is used by the terminal to receive control signaling from the first base station, wherein the radio identifier and the control channel resource is received by the terminal from the first base station when the terminal initially accesses the first base station, and wherein the first base station receives the radio identifier and the control channel resource from the controller; and
wherein the terminal can use the control channel resource to separately receive control signaling from the second base station and control signaling from the first base station.

Abstract
In a terminal handover method, a controller sends a radio identifier and a control channel resource of a terminal that are configured by the controller to the terminal. When the terminal is located in a coverage area of a first base station, the controller sends the radio identifier and the control channel resource of the terminal to the first base station. The controller determines that the terminal is located in a coverage area of a second base station, and sends the radio identifier and the control channel resource of the terminal to the second base station. The terminal receives the control signalling sent from the first base station and the second base station separately by using the control channel resource.

1. A method, comprising:
-
determining, by a controller, that a terminal, which has been located in a coverage area of a first base station, moves into a coverage area of a second base station; sending, by the controller, to the second base station, a radio identifier of the terminal, and a control channel resource that is configured by the controller for the terminal, and that is used by the terminal to receive control signaling from the first base station, wherein the radio identifier and the control channel resource is received by the terminal from the first base station when the terminal initially accesses the first base station, and wherein the first base station receives the radio identifier and the control channel resource from the controller; and wherein the terminal can use the control channel resource to separately receive control signaling from the second base station and control signaling from the first base station. - View Dependent Claims (2, 3, 4, 5, 6, 18)

7. A method, comprising:
-
receiving, by a second base station, from a controller, a radio identifier of a terminal and a control channel resource that is configured by the controller for the terminal to use to receive control signaling from a first base station, wherein the controller sends the radio identifier and the control channel resource to the second base station after the controller has determined that the terminal, which has been in a coverage area of the first base station, moves into a coverage area of the second base station, wherein the radio identifier and the control channel resource is received by the terminal from the first base station when the terminal initially accesses the first base station, and wherein the first base station receives the radio identifier and the control channel resource from the controller; sending, by the second base station, control signaling to the terminal by using the control channel resource received from the controller; and transmitting, by the second base station, data on a shared channel between the second base station and the terminal. - View Dependent Claims (8, 9, 10, 19, 20)

11. A controller, comprising:
-
a transceiver circuit; a non-transitory memory storing a program; and a processor, wherein the program comprises instructions that cause the processor to determine that a terminal, which has been located in a coverage area of a first base station, moves into a coverage area of a second base station; wherein the transceiver circuit is configured to send to the second base station, a radio identifier of the terminal and a control channel resource that is configured by the controller for the terminal, and that is used by the terminal to receive control signaling from the first base station, and when the terminal initially accesses the first base station, send the radio identifier and the control channel resource to the first base station, wherein the first base station sends the radio identifier and the control channel resource to the terminal; and wherein the terminal can use the control channel resource to separately receive control signaling from the second base station and control signaling from the first base station. - View Dependent Claims (12, 13, 14, 15, 16)

17. A base station, comprising:
-
a first interface circuit; and a second interface circuit; wherein the first interface circuit is configured to; receive, from a controller, a radio identifier of a terminal and a control channel resource configured by the controller for the terminal to use to receive control signaling from another base station, wherein the controller sends the radio identifier and the control channel resource to the base station after the controller has determined that the terminal, which has been in a coverage area of the other base station, moves into a coverage area of the base station, wherein the radio identifier and the control channel resource is received by the terminal from the other base station when the terminal initially accesses the other base station, and wherein the other base station receives the radio identifier and the control channel resource from the controller; and send control signaling to the terminal by using the control channel resource; and wherein the second interface circuit is configured to transmit data on a shared channel between the base station and the terminal.
