Abstract
A Gateway Mobile Switching Center (GMSC) of a home Public Land Mobile Network (PLMN) is provided. In one embodiment, the GMSC is configured, for receiving a roaming caller originated call from a visited PLMN including a Routing Number (RN), validating the RN against configured Network Camel Subscription Information (N-CSI) in response to receiving the roaming caller originated call, and sending a home network issued Initial Detection Point (IDP) to a Service Control Point (SCP) of the home PLMN in response to the RN being successfully validated. The home network issued IDP includes said RN. The GMSC is further configured for receiving at least a portion of information for facilitating connection of the roaming caller originated call from the SCP of the home PLMN and facilitating connection of the roaming caller originated call in response to receiving the at least portion of the information.
