A mobile radio network includes a number of mobile radio systems, each having a mobile radio services switching center which conveys calls between a number of cordless subscribers and a public switched telephone network which is common to the mobile radio systems which convey calls between a number of cordless subscribers, and a public switched telephone network which is common to the mobile radio systems which convey calls between wire-connected subscribers and also to the cordless subscribers via the mobile radio switching centers. If a cordless subscriber has roamed from its home system to a visitor system, a call from a third system can be transferred generally over the home system and the public network to the subscriber. A service node is assigned to each of the mobile radio systems and each such node keeps an account of where the home subscribers of respective mobile radio systems are located and, in cooperation with other service nodes, can connect a call from a subscriber in the third mobile radio system to the roaming subscriber without needing to load the remaining systems. The system also includes corresponding connection procedures, a subscriber telephone set and a method of registration in the network. |
