The present invention proposes a method for enabling a subscriber entity to actively communicate in a communication network, a subscriber entity being identified by at least one assigned subscriber identity (IMSI, MSISDN), said communication network comprising at least one database entity of a first type () keeping a first record of data of subscriber entities enabled to actively communicate in a communication network, the method comprising the steps of: storing said at least one assigned subscriber identity of at least one subscriber entity not enabled to actively communicate in said communication network in a database entity () of a second type, informing (SS) said database entity () of said second type about a need to enable said at least one not enabled subscriber entity to actively communicate in said communication network, and, upon being informed, transferring (S) information related to a subscriber entity not enabled, from said database () of said second type to a selected one () of said at least one database entity of said first type (). Also, the present invention proposes an accordingly adapted database entity of the above mentioned second type and a register entity for interaction with said database entity of said second type.

Method for enabling a subscriber entity to actively communicate in a communication network

The invention relates to a method and an arrangement against fraudulent use in a telecommunications network. The invention is based on the idea that at least one fraud profile identified by an identifier is created and the identifier is included in the subscriber data of some subscribers. Based on this identifier the fraud restriction parameters of the subscriber are retrieved from the subscriber's fraud profile, and these fraud restriction parameters are used in detecting and indicating possible fraudulent use. The fraud restriction parameters include values for different service limits, such as the maximum number of call forwarding re-quests and/or the maximum number of location updates during a certain period, and possibly at least for some features an action parameter related to a service limit and implemented when the service limit is reached.
