System and method for routing in a cellular digital packet data network |
摘要 |
Routing of data in a mobile radiotelephone system to an intended recipient roaming mobile end station (M-ES) is facilitated by determining if the M-ES is within the same geographic area of the originating data source. If the M-ES is within the same geographic area as verified by interrogation of the local mobile data interface station, then data is sent directly to the intended M-ES without transmission to the mobile end station's home mobile data interface station. If the intended recipient M-ES is not currently located within the same geographic area served by the originating data source, then the data is transmitted to the M-ES's home mobile data intermediate station where the last known location of the roaming M-ES is stored and then on to the appropriate mobile data intermediate station for transmission to the intended M-ES.
