Abstract

Methods and systems are provided for implementing an alternate operational-data transmission scheme for LCIB systems. According to an embodiment, an LCIB provides service to at least one mobile station on a first wireless network, the provision of service comprising (i) providing an air interface according to a first wireless technology, (ii) providing a backhaul connection over a packet-data network to a service-provider network, and (iii) bridging the air interface and the backhaul connection. The LCIB collects operational data, which the LCIB transmits to a server over a second wireless network according to a second wireless technology, where the second wireless network is different than the first wireless network, and the second wireless technology is different than the first wireless technology.

Claims

1. A method carried out by a low-cost Internet base station (LCIB) that has a backhaul connection over a packet-data network to a service-provider network, the method comprising:

the LCIB providing wireless service to at least one mobile station on a first wireless network, wherein providing wireless service on the first wireless network comprises (i) providing an air interface according to a first wireless technology and (ii) bridging the air interface and the backhaul connection;

the LCIB collecting operational data pertaining to the wireless service that the LCIB provides to the at least one mobile station on the first wireless network according to the first wireless technology; and

the LCIB transmitting the operational data to an operational-data server over a second wireless network according to a second wireless technology, wherein the second wireless network is different than the first wireless network, and wherein the second wireless technology is different than the first wireless technology,

wherein the LCIB transmits the operational data to the operational-data server in a manner that does not involve the LCIB transmitting the operational data to the operational-data server via the backhaul connection,

wherein transmitting the operational data to the operational-data server comprises transmitting the operational data in response to estimating a load on the second wireless network to be less than a threshold level, and

wherein estimating the load on the second wireless network to be less than the threshold level comprises determining that a reverse activity bit (RAB) is cleared.

2. The method of claim 1, wherein a nearby macro network also provides service on the first wireless network according to the first wireless technology.

3. The method of claim 2, wherein the nearby macro network comprises a core packet network, and wherein the operational-data server resides on the core packet network.

4. The method of claim 2, wherein the nearby macro network comprises a core packet network, and wherein the operational-data server does not reside on the core packet network.

5. The method of claim 1, wherein a nearby macro network provides service on the second wireless network according to the second wireless technology.

6. The method of claim 1, wherein the first wireless technology is code division multiple access (CDMA).

7. The method of claim 1, wherein the second wireless technology is Evolution Data Optimized (EV-DO).

8. The method of claim 1, wherein the packet-data network comprises the Internet.

9. The method of claim 1, wherein the operational data comprises at least one of a number of dropped calls, a number of blocked calls, an amount of data throughput, an access-quality metric, a voice-quality metric, an auto-configuration parameter, an average, a summary, and a report.

10. The method of claim 1, wherein transmitting the operational data to the operational-data server over the second wireless network according to the second wireless technology comprises establishing a packet-data session with the second wireless network.

11. The method of claim 1, wherein the LCIB transmitting the operational data to the operational-data server comprises the LCIB retransmitting the operational data to the operational-data server if the LCIB does not receive an acknowledgement from the operational-data server within a timeout period.

12. The method of claim 1, further comprising the LCIB transmitting operational data to the operational-data server via the backhaul connection in response to at least one of the following conditions prevailing for at least a threshold amount of time:

(i) the load on the second wireless network exceeding the threshold level and (ii) the second wireless network being unavailable.

13. A low-cost Internet base station (LCIB) comprising:

a code division multiple access (CDMA) interface;

an Evolution Data Optimized (EV-DO) interface;

a backhaul connection over a packet-data network to a service provider network;

a processor; and

data storage comprising instructions executable by the processor to;

use the CDMA interface to provide wireless service to at least one mobile station on a CDMA network, wherein providing wireless service on the CDMA network comprises bridging the CDMA interface and the backhaul connection;

collect operational data pertaining to the wireless service that the LCIB provides to the at least one mobile station on the CDMA network; and

use the EV-DO interface to transmit the operational data to an operational-data server over an EV-DO network,

wherein the LCIB transmits the operational data to the operational-data server in a manner that does not involve the LCIB transmitting the operational data to the operational-data server via the backhaul connection,

wherein transmitting the operational data to the operational-data server comprises transmitting the operational data in response to estimating a load on the EV-DO network to be less than a threshold level, and

wherein estimating the load on the EV-DO network to be less than the threshold level comprises determining that a reverse activity bit (RAB) is cleared.
