Abstract
A roaming arrangement enables roaming between different types of networks in a telecommunication system that includes a first standardized type of mobile network, a so-called home network, and a second standardized type of mobile network, a so-called guest network. A subscriber has an identity that is common for both the home network and the guest network. The roaming arrangement includes a signal handling arrangement, at least one home interface towards the home network, and at least one guest interface towards the guest net. A first signalling format between the arrangement and the home network is of the same type as a corresponding format in the home network. Also, a second signalling format between the arrangement and the guest network is of the same type as a corresponding format in the guest network.
