Switch the active user identity of the communication terminal

Abstract

A method of switching active subscriber identities of a communication terminal capable of having only one active subscriber identity at a time is disclosed. Switching of the active subscriber identity from the first subscriber identity to the second subscriber identity is initiated. At least one parameter associated with an expiry moment of a timer associated with the first user identification is stored. The first user identity is deactivated and the second user identity is activated. If a handover of an active subscriber identity from the second subscriber identity to the first subscriber identity is initiated and the first subscriber identity is activated, it may be determined whether a timer associated with the first subscriber identity has expired. Network registration of the first subscriber identity may only be performed when the moment of expiry of the timer associated with the first subscriber identity has elapsed. Corresponding computer program products, controllers, devices and communication terminals are also disclosed.

Description

technical field [0001] The present invention relates generally to the field of communication terminals and methods used in such terminals. The invention relates more particularly to the switching of the active subscriber identity of a communication terminal. Background technique [0002] In typical cellular applications, an active subscriber identity needs to be registered in the corresponding network to be able to perform communications via the network. For example, such communications may include making and receiving calls, SMS (Short Message Service), and the like. Thus, the purpose of performing a registration procedure with the network is to inform the network that the mobile terminal associated with the subscriber identity is switched on and able to receive pages and other messages from the network. [0003] When a subscriber identity performs de-registration from the network, the purpose is to inform the network that the mobile terminal associated with the subscribe...

Problems solved by technology

Some problems are usually more pronounced in multi-subscriber id devices, for example, latency issues (delays due to the problems described above take up a fraction of the total time required for switching of subscriber identities in multi-subscriber id devices than in single-subscriber id devices. part of the total time required for the switching of the subscriber identity in the subscriber identity device)
