The present invention provides a method of interworking to support global roaming across circuit-switched and packet-switched domains. Embodiments of the methods include selecting a first routing number that identifies the mobility manager as a gateway to the originating domain. The selection is performed at a mobility manager in response to receiving a request from a first gateway in an originating domain to locate a user. Embodiments of the method further include identifying a second gateway that serves the user in a destination domain using a first user identifier included in the request received from the first gateway. Embodiments of the mobility manager can store information associating the first routing number with a second routing number that identifies the second gateway. |
