1. A method for managing subscriber information in a mobile communication network, the method comprises:
- obtaining information on a subscriber,generating a first inquiry at a first instant of time to at least two subscriber registers for inquiring if the subscriber is registered in at least two subscriber registers,receiving a first response to the first inquiry,generating a second inquiry at a second instant of time differing from the first instant of time to the at least two subscriber registers for inquiring if the subscriber is registered in at least two subscriber registers from the at least two subscriber registers,receiving a second response to the second inquiry,determining on a basis of the first response and the second response if the subscriber is registered in at least two subscriber registers at the first instant of time and at the second instant of time, andin response to a determination that the subscriber is registered in at least two subscriber registers at the first instant of time and at the second instant of time generating a message canceling the registration of the subscriber at least to all those subscriber registers into which the subscriber is registered to.

Abstract
The invention relates to a solution for managing subscriber information in a mobile communication network. In the solution information on a subscriber is obtained and inquiries are generated to a plurality of subscriber registers at a plurality of instants of time. The inquiries are performed in order to determine if the subscriber is registered in the subscriber registers at the instants of time. If this is the case a message is generated for canceling the registration of the subscriber in subscriber registers. The solution is based on a method, a network node, a computer program code and a system.
