Abstract
An arrangement for providing voice dialing service to wireless subscribers when they are not being served by their home mobile switch, and service node. When a voice dialing request from a roamer is detected, the voice dialing data file of the roamer is requested by a broadcast message from the home service node of the roamer. The home service node responds to the broadcast request by transmitting the voice dialing data file to the requesting service node. The requesting service node retains the voice dialing data file as long as there are sufficiently frequent requests (e.g., once per day), for voice dialing service from the roamer. Advantageously, this arrangement allows voice dialing service to be provided to roamers as well as to mobile stations in their home area.
