Localization of disturbance in a network composed of wireless links

A controller entity for localizing disturbance in a network comprising wireless links that extend between pairs of end-points, wherein each of the end-points is composed of components, wherein each of the wireless links is associated with site data defining an abstracted representation of the components per end-point per wireless link, the controller entity comprising:

• a compare module configured to compare time-series sequences for pairs of the wireless links with each other, wherein each of time-series sequences is composed of link attenuation values for one of the wireless links, and wherein the pairs of wireless links for which the time-series sequences are compared to each other have one of the end-points in common;
• an identify module configured to identify, based on the compared time-series sequences, that performance of one of the pairs of the wireless links is impaired by a disturbance caused at the end-point that is common for both the wireless links of the one of the pairs of the wireless links;
• and
• a localize module configured to localize which component at the common end-point that is responsible for causing the disturbance by comparing the site data of the common end-point for the wireless links of the one of the pairs of the wireless links to each other.

A method for localizing disturbance in a network comprising wireless links that extend between pairs of end-points, wherein each of the end-points is composed of components, wherein each of the wireless links is associated with site data defining an abstracted representation of the components per end-point per wireless link, wherein the method is performed by a controller entity, and wherein the method comprises:

• comparing time-series sequences for pairs of the wireless links with each other, wherein each of time-series sequences is composed of link attenuation values for one of the wireless links, and wherein the pairs of wireless links for which the time-series sequences are compared to each other have one of the end-points in common;
• identifying, based on the compared time-series sequences, that performance of one of the pairs of the wireless links is impaired by a disturbance caused at the end-point that is common for both the wireless links of the one of the pairs of the wireless links;
• and
• localizing which component at the common end-point that is responsible for causing the disturbance by comparing the site data of the common end-point for the wireless links of the one of the pairs of the wireless links to each other.

A computer program for localizing disturbance in a network comprising wireless links that extend between pairs of end-points, wherein each of the end-points is composed of components, wherein each of the wireless links is associated with site data defining an abstracted representation of the components per end-point per wireless link, the computer program comprising computer code which, when run on processing circuitry of a controller entity, causes controller entity to:

• compare time-series sequences for pairs of the wireless links with each other, wherein each of time-series sequences is composed of link attenuation values for one of the wireless links, and wherein the pairs of wireless links for which the time-series sequences are compared to each other have one of the end-points in common;
• identify, based on the compared time-series sequences, that performance of one of the pairs of the wireless links is impaired by a disturbance caused at the end-point that is common for both the wireless links of the one of the pairs of the wireless links;
• and
• localize which component at the common end-point that is responsible for causing the disturbance by comparing the site data of the common end-point for the wireless links of the one of the pairs of the wireless links to each other.
