摘要： A method for facilitating inter-PLMN (Public Land Mobile Network) roaming comprises a plurality of operations. A home PLMN of a caller's wireless communication device performs an operation for determining that the caller's wireless communication device is not located in the home PLMN and, in response to determining that the caller's wireless communication device is not located in the home PLMN, an operation for facilitating a call routing service in a Service Control Point (SCP) of the home PLMN. The call routing service causes a call originated by the caller's wireless communication device while roaming in a visited PLMN to be routed back to a Gateway Mobile Switching Center (GMSC) of the home PLMN thereby allowing the home PLMN to have control over the roaming caller originated call and to have limited dependency on the visited PLMN.
