Abstract
An operator's terminal (2) determines a churn risk value associated with a first UE (User Equipment) belonging to a group of operator-connected UEs of a telecommunication system, each UE of the group associated with an initial churn risk value, which depends on the usage. Further, direct weight factors are determined (51) for each direct connection to the first UE, and linked weight factors are determined (52) for each non-direct connection, the weight factors indicating the connectivity between the UEs. Then, the churn risk value is determined (54) based on the initial churn risk values and said weight factors.

A method for an operator's terminal in a telecommunication network of determining a churn risk value associated with a first User Equipment belonging to a group of operator-connected User Equipments, each User Equipment of the group associated with a calculated initial churn risk value, which depends on the usage, the method comprising:
- determining a direct weight factor for direct connections between the first User Equipment and other User Equipments of the group;
- determining a linked weight factor for non-direct connections between the first User Equipment and other User Equipments of the group, based on the direct weight factors of the connection;
- calculating a weighted churn value for each of said direct and non-direct connections to the first User Equipment from the other User Equipments of the group, based on each determined weight factor and the initial churn risk value associated with the corresponding other User Equipment;
- determining a churn risk value for the first User Equipment by adding each calculated weighted churn risk value to the initial churn risk value associated with the first User Equipment.
An operator's terminal connectable to a telecommunication network, the terminal comprising a communication unit, a data collecting unit and a data analyzing unit, each unit provided with a processing unit, wherein the terminal is configured to determine a churn risk value associated with a first User Equipment by:
- determining a direct weight factor for direct connections between said first User Equipment and other User Equipments belonging to a group of operator-connected User Equipments, wherein each User Equipment of the group is associated with a pre-calculated initial churn risk value;
- determining a linked weight factor for non-direct connections between said first User Equipment and the other User Equipments of the group, based on the determined direct weight factors of the connection;
- calculating a weighted churn risk value for each of said direct and non-direct connections, based on each determined weight factor and a pre-calculated initial churn risk value associated with the corresponding other User Equipment, based on the usage;
- determining a churn risk value for the first User Equipment by adding each calculated weighted churn risk value to the initial churn risk value associated with said first User Equipment.
