Abstract
The invention relates to a method a method for routing calls and messages in a communication system. In the method a mobile station registers to a call control node using a logical name. The logical name is mapped in a directory to an international mobile subscriber identity. The call control node performs a location update to a home location register using the international mobile subscriber identity. The mobile station is reached using a called party number. As a terminating call or message is received to a core network, a roaming number is allocated for the mobile station, and the call or message is routed to the call control entity currently serving the mobile station. The call control node translates the called party number to the logical name using the directory.
