A method of detecting a defect in a connecting member of a radio unit in a radio site includes applying an artificial radio traffic load to a first radio unit and at least a second radio unit, such that the radio traffic load experienced by the first and the second radio unit is at a same level, measuring power supplied to the first radio unit via a first connecting member and power supplied to the second radio unit via a second connecting member at an end of each connecting member terminating at a device configured to supply power to the radio units, and determining from the measured power and an expected nominal power loss of the first and the second connecting member if there is power loss in at least one of the first and the second connecting member indicating a defect.

The present disclosure relates to a method of controlling allocation of mobile devices (-) to frequency bands in a radio site (), and a device () performing the method. In an aspect, a method of a radio base station () of controlling allocation of mobile devices (-) to frequency bands in a radio site () is provided. The method comprises estimating (S) power consumption of the radio base station () caused by radio traffic of the mobile devices (-) in each frequency band of the radio site (), determining (S) whether or not power consumption of the radio base station () is decreased by reallocating at least one of the mobile devices (-) from one frequency band to another frequency band, while not exceeding a power headroom limit of said another frequency band, and if so reallocating (S) said at least one mobile device from said one frequency band to said another frequency band.

A method and detector for detecting anomalies among media event sequences are disclosed. One method includes obtaining a first profile of media event data over a first time period, where the first profile is a first distribution of different media event sequences. Each sequence is associated with a number of occurrences of the sequence and the first profile having a first profile vector. The method further includes obtaining a second profile of media event data over a second time period less than the first time period. The second profile is a second distribution of the different media sequences and the second profile having a second profile vector. The method also includes comparing the first profile vector and the second profile vector, and determining one of a presence and absence of at least one anomaly in the second profile vector of media event data based on the comparison.

A method and a migration managing module for managing a migration of a service. The migration managing module determines a point in time relating to completion of the migration of the service based on resource requirements related to the service. For each radio network node a respective impact on a quality of the service is estimated. Moreover, the migration managing module selects from among servers at least one respective target server for which the respective server location measure of said at least one respective target server matches the respective radio network node location measure of said each radio network node, thereby obtaining a set of target servers comprising said at least one respective target server for said each radio network node. For each target server, a respective cost of the migration based on the resource requirements related to the service is determined. A respective tendency as a function of said each probability value, the respective cost and the respective impact is determined. A target server of the set of target servers based on tendencies is selected. The migration of the service from the source server to the target server is performed. A computer program and a carrier therefor are also disclosed.
