  • Switching active subscriber identity of a communication terminal
    Patent number: 9596591
    Abstract: A method is disclosed of switching the active subscriber identity of a communication terminal which is capable at each moment in time of having only one active subscriber identity. An active subscriber identity switch from a first subscriber identity to a second subscriber identity is initiated. At least one parameter associated with a time of expiry of a timer associated with the first subscriber identity is stored. The first subscriber identity is deactivated and the second subscriber identity is activated. If an active subscriber identity switch from the second subscriber identity to the first subscriber identity is initiated and the first subscriber identity is activated, it may be determined whether the time of expiry of the timer associated with the first subscriber identity has passed. Network registration of the first subscriber identity may be performed only if the time of expiry of the timer associated with the first subscriber identity has passed.

  • Subscriber identity switch of a communication terminal
    Patent number: 9204413
    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.
