ABSTRACT:
The present invention relates generally to a method and apparatus for selecting a visited mobile radio network upon international roaming. More particularly, the invention relates to selecting a mobile radio network with regard to the support given by the mobile radio network in respect of a network feature. An international roaming indication is provided to the home mobile radio network of a mobile station, indicating that the mobile station is roaming, or is intending to roam, internationally. Such international roaming indication comprises information about geographic region(s) in which it is likely that the mobile station will communicate. The home mobile radio network then selects at least one mobile radio network, operated in the geographic region(s) and supporting the network feature needs of the mobile station, and sends information to the mobile station regarding the selected mobile radio network(s).
