A method and system for forwarding calls in telecommunication networks are provided. More particularly, control of late call forwarding logic and routing is placed at the home network Gateway MSC and HLR, thus removing the home network service provider's dependency on the visited network capabilities.
1. A method of routing calls in a communication network, the method comprising:
receiving a call from a calling party directed to a roaming subscriber at a first network entity in the subscriber's home network;
obtaining call routing information for the subscriber from a database in the subscriber's home network and starting an answer timer;
determining the current location of the subscriber;
connecting the call to a second network entity servicing the subscriber in a visited network;
upon receiving an indication that the subscriber has not answered the call, releasing the connection to the second network entity;
obtaining late call forwarding information for the subscriber from the database; and
completing the call to a late call forwarding destination in the home network based on the late call forwarding information.
