Subscriber identity switch of a communication terminal

摘要

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.

1. A method of switching subscriber identity between a first and second telecommunication stack of a communication terminal, wherein the communication terminal is a multiple subscriber identity terminal, the method comprising:
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; determining whether a value of at least one parameter from a first group of parameters associated with the first subscriber identity in the first telecommunication stack corresponds to a value of a corresponding at least one parameter from the first group of parameters associated with the first subscriber identity in the second telecommunication stack; and performing network registration of the first subscriber identity only if the value of the at least one parameter from the first group of parameters associated with the first subscriber identity in the first telecommunication stack does not correspond to the value of the corresponding at least one parameter from the first group of parameters associated with the first subscriber identity in the second telecommunication stack.
