Abstract
A method for handling a jamming signal in a wireless network includes obtaining network measurement data collected by a wireless network element. A first performance information relating to a Key Performance Indicator, data collected during a quiet time, or a report on a bogus Physical Random Access Channel signal, or a combination thereof, is selected from the network measurement data. The first performance information is examined with respect to a first reference information. An action is initiated if the examination of the first performance information indicates the presence of a potential jamming signal.
Claims17
A method for handling a bogus Physical Random Access Channel (PRACH) signal in a wireless network, the method comprising:
- obtaining network measurement data collected by a wireless network element, the network measurement data including a Key Performance Indicator (KPI) used by the network to evaluate performance or data collected during a quiet time;
- and
- determining whether a bogus PRACH signal is present in the network by examining the network measurement data with respect to a first reference information,
- wherein the network measurement data is the KPI, the method further comprising:
- instructing at least one network element to not transmit in PRACH frequencies at a predetermined quiet time;
- collecting data received in the PRACH frequencies during the quiet time;
- and
- analyzing the data received in the PRACH frequencies to determine whether the bogus PRACH signal is present.
A system for handling a bogus Physical Random Access Channel (PRACH) signal in a wireless network, the system comprising:
- a processor;
- and
- a non-transitory computer readable medium with computer executable instructions stored thereon which, when executed by the processor, perform a method comprising:
- obtaining network measurement data collected by a wireless network element, the network measurement data including a Key Performance Indicator (KPI) used by the network to evaluate performance or data collected during a quiet time;
- and
- determining whether a bogus PRACH signal is present in the network by examining the network measurement data with respect to a first reference information,
- wherein the network measurement data is the KPI, the method further comprising:
- instructing at least one network element to not transmit in PRACH frequencies at a predetermined quiet time;
- collecting data received in the PRACH frequencies during the quiet time;
- and
- analyzing the data received in the PRACH frequencies to determine whether the bogus PRACH signal is present.
A method for handling a bogus Physical Random Access Channel (PRACH) signal in a wireless network, the method comprising:
- obtaining network measurement data collected by a wireless network element, the network measurement data including a Key Performance Indicator (KPI) used by the network to evaluate performance or data collected during a quiet time;
- determining whether a bogus PRACH signal is present in the network by examining the network measurement data with respect to a first reference information;
- and
- when the bogus PRACH is present:
- determining whether a frequency assignment (FA) for PRACH frequencies is available, and
- when the FA is available, applying the FA to the PRACH frequencies.
