Abstract
A virtual mobile node (22) has a pseudo HLR (23) and a pseudo MSC (24). It transfers an SMS message between an entity in a foreign mobile network having a different technology to an SMS entity connected to the local network. The pseudo HLR and MSC are both located in the home network but operate with the protocol of the foreign network. Thus, communication between the home and foreign networks is via SS7 signalling.
