Abstract

It is described a method for transferring a base station of a wireless communication network from a standby mode to a fully activated mode. The method includes sending an activation signal from a user equipment (UE) to the base station. The method further includes receiving the activation signal by the base station and transferring the base station (BS2) to the fully activated mode in response to the reception of the activation signal.

Claims

1. Method for transferring a base station of a wireless communication network from a standby mode to a fully activated mode, the method comprising

sending an activation signal from a user equipment to the base station,

receiving the activation signal by the base station and transferring the base station to the fully activated mode in response to the reception of the activation signal.

2. The method as set forth in claim 1, further comprising switching off a transmitting unit of the base station so that the base station is in the standby mode.

3. The method as set forth in claim 2, wherein switching off the transmitting unit of the base station is performed after a specific time of inactivity of the user equipment (UE).

4. The method as set forth in claim 1, wherein the standby mode is a partially deactivated mode.

5. The method as set forth in claim 1, wherein the activation signal is a RACH burst signal with a specific preamble sequence.

6. The method as set forth in claim 5, wherein the preamble is derived from a base station downlink scrambling code or a physical cell identification (PID).

7. The method as set forth in claim 1, wherein the user equipment (UE) is assigned to a specific base station.

8. The method as set forth in claim 7, wherein the user equipment (UE) is adapted to detect its current location for determining if it is located in a range of its assigned base station and to send the activation signal when in the range of its assigned base station.

9. The method as set forth in claim 1, wherein, after sending the activation signal, the user equipment (UE) moves to radio resource active state.

10. The method as set forth in claim 1, wherein the user equipment (UE) is synchronized to a wide area base station before sending the activation signal.

11. The method as set forth in claim 1, wherein the user equipment (UE) is adapted to send the activation signal during specific time intervals and/or for specific frequency resources.

12. The method as set forth in claim 1, further comprising detecting whether the user equipment (UE) is authorized to establish a connection with the base station.

15. A program element for transferring a base station of a wireless communication network from a standby mode to a fully activated mode, the program element, when being executed by a data processor, is adapted for controlling the method as set forth in claim 1.

13. User equipment (UE) comprising a transmitting unit for transmitting an activation signal to a base station, which is in a standby mode, wherein the activation signal is adapted to transfer the base station from a standby mode to a fully activated mode.

14. Base station comprising

a receiving unit for receiving an activation signal from a user equipment, and

a unit for transferring the base station from a standby mode to a fully activated mode.
