Abstract

A method is disclosed, comprising: collecting, at an in-vehicle base station, reports from a plurality of user equipments (UEs); storing, at the in-vehicle base station, reports collected from the plurality of UEs into a database; forwarding, from the in-vehicle base station to a coordinating server, stored reports into the database; performing, at the coordinating server, data analysis of the received reports; and sending, from the coordinating server to a base station, an instruction to update at least one configuration parameter of the base station, thereby improving data collection and data processing for radio frequency cell optimization.

First claim

The invention claimed is:

1. A method, comprising:
collecting, at an in-vehicle base station, reports from a plurality of user equipments (UEs);
storing, at the in-vehicle base station, reports collected from the plurality of UEs into a first database;
forwarding, from the in-vehicle base station to a coordinating server, stored reports into a second database at the coordinating server;
performing, at the coordinating server, data analysis of the received reports; and
sending, from the coordinating server to a base station, an instruction to update at least one configuration parameter of the base station;
wherein the in-vehicle base station forwards the stored reports to the coordinating server via a wireless backhaul link,
wherein the reports comprise radio reports and performance reports,
wherein the radio reports are analyzed for radio frequency planning of a plurality of base stations,
wherein the performance reports are utilized for improving user applications performance statistics at the plurality of UEs for throughput and latency, thereby improving data collection and data processing for radio frequency cell optimization and wherein the performance reports include location of the in-vehicle base station and measurement of at least one of: throughput, statistics of successful or failed connection attempts, and statistics of call completion at a user equipment (UE);
determining, at the coordinating server, based on the data analysis, a geographic location having RF measurement statistics below a threshold set by an operator of the core network;
sending, from the coordinating server to the in-vehicle base station, an instruction to drive to the geographic location; and
activating, at the in-vehicle base station, radio access network to allow the plurality of UEs to attach to the in-vehicle base station to access the core network
wherein the collected reports include application performance-related parameters for at least two of telephone calls, video streaming, and file transfer.

2. The method of claim 1 , wherein the radio reports include location of the in-vehicle base station and measurement of at least one of: Reference Signal Received Power (RSRP), Reference Signal Received Quality (RSRQ), and a signal quality measurement relating to Signal-to-Noise Ratio (SNR).

3. The method of claim 1 , wherein the instruction to update the configuration parameter is at least one of to change transmit power level at the base station, update antenna alignment, handover of a user equipment (UE) of the plurality of UEs to a neighbor base station, allow or deny the UE services of the base station.

4. The method of claim 1 , wherein the in-vehicle base station has radio access network deactivated.

5. The method of claim 1 , wherein the forwarding, from the in-vehicle base station to the coordinating server, of the stored reports occurs when the in-vehicle base station has backhaul link Quality of Standard (QoS) measurement above a threshold set by an operator of the core network.

6. The method of claim 1 , further comprising:
calculating, at the coordinating server, bandwidth usage of a mesh network of a plurality of base station; and
determining, at the coordinating server, change in number of base stations of the mesh network.

7. The method of claim 1 , wherein at least one user equipment (UE) of the plurality of UEs is running an application to report radio frequency measurements and application performance results to the base station, the base station sends reports from the UE to the coordinating node for performing analysis.

8. The method of claim 1 , further comprising sending, from the coordinating server to the in-vehicle base station, instruction to provide radio access to the plurality of UEs upon determining the in-vehicle base is at emergency location.

9. The method of claim 1 , further comprising sending, from the coordinating server to the in-vehicle base station, instruction to activate relay mesh node functionality.

10. The method of claim 1 , further comprising activating, at the in-vehicle base station, radio access interface for a UE to attach to the in-vehicle base station; and collecting, at the in-vehicle base station, measurement of interference with neighbor cells and radio frequency (RF) measurement reports including one or more of EARFCN, signal strength, PLMN ID, PCI, and ECGI.

11. The method of claim 1 , wherein the in-vehicle base station is a multi-radio access technology (multi-RAT) base station supporting at least two access technologies of 2G, 3G, 4G, 5G, Wi-Fi, and WiMax.

12. The method of claim 1 , further comprising collecting, at an in-vehicle base station, reports from a plurality of user equipments (UEs) at a sniffer baseband circuit in communication with a primary baseband circuit.

13. The method of claim 1 , wherein the application performance-related parameters include at least two of: latency, video quality; audio quality; throughput to a server; successful attempts to access a server; call completions; call throughput; file transfer throughput; file transfer completion.

14. The method of claim 1 , further comprising assessing minimum service quality for a specific number of users.

15. The method of claim 1 , further comprising assigning a particular quality of service parameter to deprioritize the forwarding of the stored reports to the second database.

16. The method of claim 1 , further comprising automatically throttling uploads based on a Global Positioning System (GPS) position of the in-vehicle base station.

17. The method of claim 1 , further comprising changing a network configuration relating to one or more of RF transmission power, antenna realignment, optimization of a core network transport, a packet size, a frame size, a queue depth.

18. The method of claim 1 , further comprising providing dynamic coverage optimization for a first responder access network.

19. The method of claim 1 , further comprising determining whether to activate a mesh network node based on the collected reports.

20. The method of claim 1 , further comprising performing closed loop self-organizing network (SON) functionality based on the collected reports.
