Abstract

A method and system controls timing of network performance information logging of a cellular network by configuring a mobile device to automatically collect data about physical characteristics of the cellular network and log that data. The mobile device initially receives network performance information logging configuration from its registered cellular network. Based on the configuration, the mobile device configures itself to collect and log the network performance information relating to physical characteristics of the cellular network. While in idle mode, the mobile device collects and logs the information. A logging duration timer corresponds to a specified time duration over which the mobile device logs network performance information. If the mobile device starts the logging duration timer at the time of configuration, it maintains the timer even after the transition to idle mode. The mobile device may also start the logging duration timer after it transitions to idle mode.

Claims

1. A computer-implemented method for controlling the timing of an automatic network performance measurement of a cellular network in a mobile device having a processor and a storage area, the method comprising:

receiving a configuration from the cellular network while the mobile device is operating in a connected mode, the configuration specifying parameters relating to network performance logging to be performed by the mobile device;

based on the configuration, configuring the mobile device to automatically log network performance information for the cellular network in the storage area;

starting a logging duration timer while the mobile device is operating in connected mode, wherein the mobile device is configured to perform radio frequency transmissions while in the connected mode, the logging duration timer corresponding to a specified time duration over which the mobile device logs the network performance information;

transitioning the mobile device from the connected mode to an idle mode, wherein transitioning comprises canceling at least a portion of all active timers, the at least a portion of all active timers not including the logging duration timer, wherein canceling at least a portion of all active timers includes canceling or stopping all timers except the logging duration timer and at least one additional timer;

logging the network performance information according to the configuration; and

stopping logging the network performance information in response to the logging duration timer expiring;

wherein the logging of the network performance information is a part of a Minimization of Drive Tests (MDT) procedure;

wherein the logging duration timer is timer T326 or timer T330.

2. The method of claim 1, wherein the specified time duration is specified by the cellular network in the configuration.

3. The method of claim 1, wherein the specified time duration is predetermined before the mobile device receives the configuration.

4. The method of claim 1, wherein the specified time duration is one of 10 minutes, 20 minutes, 40 minutes, 60 minutes, 90 minutes, or 120 minutes.
