Abstract
A method of switching subscriber identity between a first and second telecommunication stack of a multiple subscriber identity communication terminal is disclosed. The method comprises initiating a switch for a first subscriber identity from the first telecommunication stack to the second telecommunication stack and for a second subscriber identity from the second telecommunication stack to the first telecommunication stack. It is determined whether a value of at least one network related parameter associated with the first subscriber identity in the first telecommunication stack corresponds to a value of a corresponding at least one network related parameter associated with the first subscriber identity in the second telecommunication stack. Network registration of the first subscriber identity is performed only if the value of the at least one network related parameter associated with the first subscriber identity in the first telecommunication stack does not correspond to the value of a corresponding at least one network related parameter associated with the first subscriber identity in the second telecommunication stack. Corresponding computer program product, controller, arrangement, and multiple subscriber identity communication terminal are also disclosed.
