Abstract
Embodiments of the present disclosure are directed to systems and methods for mitigating disruptions to telecommunications networks. A call setup time is determined from a network perspective. If the call setup time is sufficiently long, one or more corrective actions are taken in order to identify and/or resolve a network problem that could be contributing to the long call setup time. The corrective action(s) can include comparing call setup time performance by geographic region, comparing network-observed call setup times to user equipment-observed call setup times, and/or initiating cell reselection procedures, for example.
Claims20
A method for mitigating disruptions to a telecommunications network comprising:
- determining a setup time for a first call between a first user equipment (UE) and a second UE by determining a difference between:
- a first time at which a first call initiation indication for the first call was received from the first UE at a first radio access network (RAN) node of the network, and
- a second time at which a call delivery indication for the first call was transmitted from a second RAN node of the network to the first UE, wherein the call delivery indication indicates that the second UE has received a request to join the first call;
- determining that the setup time for the first call is above a threshold;
- and
- based on the determining that the setup time for the first call is above the threshold, performing a corrective action.
A computerized system comprising:
- one or more processors;
- and
- a non-transitory computer storage media storing computer-usable instructions that, when used by the one or more processors, cause the one or more processors to:
- determine a setup time for a first call between a first user equipment (UE) and a second UE by determining a difference between:
- a first time at which a first call initiation indication for the first call was received from the first UE at a first radio access network (RAN) node of the network, and
- a second time at which a call delivery indication for the first call was transmitted from a second RAN node of the network to the first UE, wherein the call delivery indication indicates that the second UE has received a request to join the first call;
- determine that the setup time for the first call is above a threshold;
- and
- based on the determining that the setup time for the first call is above the threshold, perform a corrective action.
One or more computer storage media storing computer-useable instructions that, when used by a computing device, cause the computing device to perform operations, the operations comprising:
- determining a setup time for a first call between a first user equipment (UE) and a second UE by determining a difference between:
- a first time at which a first call initiation indication for the first call was received from the first UE at a first radio access network (RAN) node of the network, and
- a second time at which a call delivery indication for the first call was transmitted from a second RAN node of the network to the first UE, wherein the call delivery indication indicates that the second UE has received a request to join the first call;
- determining that the setup time for the first call is above a threshold;
- and
- based on the determining that the setup time for the first call is above the threshold, performing a corrective action.
