Abstract

A method and system for improving the routing of messages in a radio communication system are disclosed. In an exemplary system, messages which originate at a mobile unit are routed through both a service center associated with the originating mobile and a service center associated with a recipient mobile. If the recipient has subscribed to an enhanced message routing service, then the home location register returns an address of the recipient's service center in response to a request for routing information. When the home location register is queried again for routing information for the same message, the enhanced message service indicator is suppressed so that the home location register returns a routing number for the equipment which is currently supporting radiocommunication with the recipient, rather than returning the service center address a second time.
