Abstract

In one aspect, a method of determining a geographical location of a base station is provided. The base station is within a coverage area of a master base station and requests geographical location information from the master base station through a first Precision Time Protocol (PTP) management message. The base station receives the geographical location information from the master base station through a second PTP management message. In addition, the base station determines the geographical location of the base station from the geographical location information included in the second PTP management message.

Claims (34)

1. A method of determining a geographical location of a base station that is within a coverage area of a master base station, the method comprising:

requesting geographical location information from the master base station via a first Precision Time Protocol (PTP) management message extended to enable a request to be included in a management Type Length Value (TLV) element of the first PTP management message, wherein the management TLV element specifies information to be reported from the master base station to the base station, the specified information including the geographical location information;

receiving the geographical location information from the master base station via a second PTP management message extended to enable the geographical location information to be included in a management TLV element of the second PTP management message; and

determining the geographical location of the base station from the geographical location information included in the second PTP management message.

2. The method of claim 1 ,

wherein the first PTP management message includes an actionField value indicating that the first PTP management message includes the management TLV element with data specifying information to be reported from the master base station upon the occurrence of a given event.

3. The method of claim 1 ,

wherein the second PTP management message includes a SET actionField value and a management TLV managementld field value which includes a value used to hold the geographical location information of the master base station, and

wherein the geographical location of the base station is determined from the geographical location information included in the management TLV element of the second PTP management message.

4. The method of claim 3 , wherein the geographical location information of the master base station includes a UTC Time Stamp, Latitude data, and Longitude data.

5. The method of claim 1 ,

wherein the master base station includes a GNSS receiver system to determine a geographical location of the master base station, and

wherein the geographical location information included in the second PTP management message includes the geographical location of the master base station.

6. The method of claim 1 , wherein the master base station is an outdoor base station and the base station is an indoor base station.

7. A wireless communication base station positioned within a coverage area of a master base station and configured to perform operations for determining a geographical location of the wireless communication base station, the operations comprising:

requesting geographical location information from the master base station via a first Precision Time Protocol (PTP) management message extended to enable a request to be included in a management Type Length Value (TLV) element of the first PTP management message, wherein the management TLV element specifies information to be reported from the master base station to the base station, the specified information including the geographical location information;

receiving the geographical location information from the master base station via a second PTP management message extended to enable the geographical location information to be included in a management TLV element of the second PTP management message; and

determining the geographical location of the wireless communication base station from the geographical location information included in the second PTP management message.

8. The wireless communication base station of claim 7 ,

wherein the first PTP management message includes an actionField value indicating that the first PTP management message includes the management TLV element with data specifying information to be reported from the master base station upon the occurrence of a given event.

9. The wireless communication base station of claim 7 ,

wherein the second PTP management message includes a SET actionField value and a management TLV managementld field value which includes a value used to hold the geographical location information of the master base station, and

wherein the geographical location of the wireless communication base station is determined from the geographical location information included in the management TLV element of the second PTP management message.

10. The wireless communication base station of claim 9 , wherein the geographical location information of the master base station includes a UTC Time Stamp, Latitude data, and Longitude data.

11. The wireless communication base station of claim 7 ,

wherein the master base station includes a GNSS receiver system to determine a geographical location of the master base station, and

wherein the geographical location information included in the second PTP management message includes the geographical location of the master base station.

12. The wireless communication base station of claim 7 , wherein the master base station is an outdoor base station and the wireless communication base station is an indoor base station.

13. A method for a base station to obtain location-proximity specific information from a master base station, comprising:

requesting the location-proximity specific information from the master base station via a first Precision Time Protocol (PTP) management message extended to enable the request to be included in a management Type Length Value (TLV) element of the first PTP management message, wherein the management TLV element specifies information to be reported from the master base station to the base station, the specified information including the location-proximity specific information; and

receiving the location-proximity specific information from the master base station via a second PTP management message extended to enable the location-proximity specific information to be included in a management TLV element of the second PTP management message.

14. The method of claim 13 , wherein the location-proximity specific information is geographical location information of the master base station.

15. The method of claim 14 , further comprising, determining a geographical location of the base station from the geographical location information of the master base station.

16. The method of claim 14 , wherein the geographical location information includes a UTC Time Stamp, Latitude data, and Longitude data.
