Abstract

A method performed by a radio base station, the method including determining a link configuration of a first communication link, the first communication link being a current communication link between a first radio equipment control (REC) device and a radio equipment (RE) device. The method further including in response to determining that a second communication link between a second REC device and the RE device is to replace the current communication link, instead of the first communication link, establishing, by the second REC device, the second communication link based on the determined link configuration of the first communication link.

First claim

What is claimed is:

1. A method performed by a radio base station, the method comprising:
establishing, by a first radio equipment control (REC) device, a first communication link between the first REC device and a radio equipment (RE) device, the first communication link being a main communication link between the first REC and the RE device;
during the establishing of the first communication link, determining a link configuration of the first communication link;
determining that a second communication link between a second REC device and the RE device is to be a new main communication link, instead of the first communication link, the second communication link being a backup communication link between the second REC device and the RE device; and
establishing, by the second REC device, the second communication link based on the determined link configuration of the first communication link.

2. The method of claim 1 , further comprising:
receiving, by the second REC device, the determined link configuration of the first communication device provided by the first REC device.

3. The method of claim 1 , wherein receiving the determined link configuration comprises:
snooping, by the second REC device, communications of the first communication link to determine the determined link configuration of the first communication link.

4. The method of claim 1 , further comprising:
storing, by the first REC device, the determined link configuration of the first communication link to a storage location; and wherein
establishing the second communication link includes reading the determined link configuration of the first communication link from the storage location.

5. The method of claim 1 , wherein the first communication link and the second communication link are the same physical communication link.

6. The method of claim 1 , wherein the first communication link and the second communication link are different physical communication links.

7. The method of claim 1 , further comprising:
in response to establishing the second communication link, entering, by the first REC device, a stand-by operating mode.

8. The method of claim 1 , wherein the first communication link and the second communication link comprising one or more internal base station interface types including a common public radio interface (CPRI) and an open base station architecture initiative (OBSAI) interface.

9. The method of claim 1 , wherein determining that the second communication link is to replace the current communication link is in response to the first REC device being unavailable.

10. A radio base station system comprising:
a radio equipment (RE) device;
a first radio equipment control (REC) device to be coupled to the RE device by a first communication link, the first REC device configured to determine a link configuration of the first communication link, the first communication link to being a main communication link between the first REC device and the RE device; and
a second REC device;
wherein the radio base station is configured to determine that a second communication link between the second REC device and the RE device is to be a new main communication link, instead of the first communication link, the second communication link being a backup communication link between the second REC and the RE device; and
wherein the second REC device is configured to establish a second communication link based on the determined link configuration of the first communication link in response to it being determining that the second communication link between the second REC device and the RE device is to replace the current communication link.

11. The radio base station system of claim 10 , the second REC device further configured to:
receive the determined link configuration of the first communication link provided by the first REC device.

12. The radio base station system of claim 10 , the second REC device further coupled to the first REC device to snoop communications of the first communication link to determine the determined link configuration of the first communication link.

13. The radio base station system of claim 10 , the first REC device further configured to:
store the determined link configuration of the first communication link to a storage location; and
the second REC device further configured to read the determined link configuration of the first communication link from the storage location.

14. The radio base station system of claim 10 , wherein the first communication link and the second communication link are the same physical communication link.

15. The radio base station system of claim 10 , wherein the first communication link and the second communication link are different physical communication links.

16. The radio base station system of claim 10 , wherein, in response to the second communication link being established, the first REC device further configured to enter a stand-by operating mode.

17. The radio base station system of claim 10 further configured to determine that the second communication link is to replace the current communication link in response to the first REC device being unavailable.

18. The radio base station system of claim 10 , wherein the first communication link and the second communication link are to be configured as one or more internal base station interface types including a common public radio interface (CPRI) and an open base station architecture initiative (OBSAI) interface.
