Abstract

A system and method of managing collection and maintenance of performance data for a wireless communications network including collecting configuration data for the network, encoding the collected configuration data and storing the data, collecting a transmitted signal, measuring a parameter of the collected signal, and encoding and storing the parameter. These steps are repeated for additional configurations of the network. The transmitted signals are transmitted by a base station or a mobile device. Further, the transmitted signals are collected by a base station or a mobile device.

Claims

1. In a wireless communications network having a plurality of base stations for communication with a plurality of mobile devices, a method of managing the collection and maintenance of performance data for the wireless communications network comprising:

(a) collecting configuration data for the wireless communications network;

(b) encoding the collected configuration data and storing the data in a first database;

(c) collecting signals by at least one base station, the signals being transmitted by the mobile device;

(d) measuring at least one parameter of the collected signal;

(e) encoding the at least one parameter and storing in a second database; and

(f) repeating steps (a)-(e) for a plurality of configurations,

wherein encoding the parameter includes associating with a temporal parameter.

2. The method of claim 1, further comprising the steps of:

(g) receiving a request for at least one measured parameter for a specified network configuration; and

(h) accessing the at least one measured parameter for the time period during which the specified network configuration existed.

3. The method of claim 2 further comprising the steps of:

(i) if the specified network configuration does not exist in the first database;

(1) accessing the at least one parameter of a network substantially similar to the specified configuration; and

(2) modifying the accessed data to correspond to the specified configuration.

9. The method of claim 2 further comprising identifying the at least one measured parameter which is not valid for the specified network configuration.

10. The method of claim 1 further comprising:

(g) estimating the network configuration as a function of a specified time; and

(h) providing at least one measured parameter valid for the estimated network configuration.

11. The method of claim 1 further comprising the steps of:

(g) receiving a request for at least one measured parameter for a specified time interval;

(h) identifying the requested at least one parameter for the specified time interval;

(i) identifying the network configurations associated with identified requested at least one parameter for the specified time interval; and

(j) identifying the identified requested at least one parameter which may have been affected by a network configuration change during the specified time interval.

4. In a wireless communication network having a configuration of communication elements for communicating with a mobile device, a method of collecting performance information related to the configuration of the network elements comprising:

(a) collecting performance data for a first configuration of network elements;

(b) encoding the collected performance data for the first configuration and storing in a database;

(c) collecting performance data by at least one base station for a second configuration of network elements;

(d) encoding the collected performance data for the second configuration and storing in a database; and

(e) predicting the performance data for a third configuration as a function of the performance data for the first and second configurations, wherein the first, second and third configurations are not the same configurations,

wherein encoding the parameter includes associating with a temporal parameter.

12. The method of claim 4 wherein the step of prediction the performance of the third configuration includes:

(i) extrapolating the performance data associated with the first network configuration;

(ii) extrapolating the performance data associated with the second network configuration; and

(iii) predicting the performance data for third network configuration by extrapolating the extrapolated performance data associated with the first and second network configurations.

13. The method of claim 4 wherein the collection of performance data is selected from the group consisting of:

continuous collection, periodic collection, intermittent collection, event-driven collection, and combinations thereof.

5. In a wireless communications network having a plurality of base stations for communication with a plurality of mobile devices, a method of managing the collection and maintenance of performance data for the wireless communications network comprising:

(a) collecting configuration data for the wireless communications network;

(b) encoding the collected configuration data and storing the data in a database;

(c) collecting signals by at least one mobile device, the signals being transmitted by at least one base station;

(d) measuring at least one parameter of the collected signal;

(e) encoding the at least one parameter and storing in a database; and

(f) repeating steps (a)-(e) for a plurality of configurations,

wherein encoding the parameter includes associating with a temporal parameter.

6. The method of claim 5, further comprising the steps of:

(g) receiving a request for at least one measured parameter for a specified network configuration; and

(h) accessing the at least one measured parameter for the time period during which the specified network configuration existed.

7. The method of claim 6 further comprising the steps of:

(i) if the specified network configuration does not exist in the data base;

(1) accessing the at least one parameter of a network substantially similar to the specified configuration; and

(2) modifying the accessed data to correspond to the specified configuration.

8. A method for evaluating the performance of a wireless communications network having a plurality of base stations for communicating with a plurality of mobile devices, comprising:

(a) collecting configuration data for the wireless communications network and storing in a database;

(b) measuring by at least one mobile device at least one parameter of the communication signals transmitted in the wireless communications network and storing in the database;

(c) receiving a request for the at least one measured parameter for a specified network configuration; and

(d) providing the requested at least one parameter that is valid for the specified network configuration,

wherein the collected configuration data and the measured at least one parameter are time stamped.
