FIELD

The exemplary and non-limiting embodiments of the invention relate generally to wireless communication systems. Embodiments of the invention relate especially to apparatuses and methods in wireless communication networks.

BACKGROUND

Wireless communication systems in usually comprise wireless user terminals, a radio access network and a core network. These components of the system exchange messages to establish a signaling connection between them to facilitate data transfer from one communication point to another communication point. The message exchange between different components of the system should be as reliable and efficient regarding the use of communication system resources as possible.

Wireless communication systems are under constant development. One aspect under development is user terminals having more than one subscription identities. There may be users who have the need to utilise more than one subscription in a same terminal. For example, one subscription maybe for home use and another for work. The communication system should be prepared to handle these situations in an efficient manner.
