In a cellular mobile telecommunication system, an intelligent network service subscriber can place an originating intelligent network (IN) service call from an area that is not supported by an IN capable mobile switching center. After determining that the call is an IN service call, the non-IN capable mobile switching center will forward the call to a specially configured IN gateway which is programmed to notify the IN subscriber's home location register and service control point. The home location register and service control point then return the appropriate routing instructions to the IN gateway, which in turn forwards the originating IN service call to the intended party.
