<p>A data interface interconnection gateway (DIIGW 160) is provided that interconnects to different wireless communication networks (120-1, 120-2). The DIIGW implements methods for determining the network location of a mobile station (111-1) from among the different networks. The DIIGW communicates data link messages with standardized air interface protocols using a data service that implements an acknowledgement mechanism. The data service can be one of: a short data service (SDS), a TErrestrial Trunked RAdio (TETRA) high speed data service (TEDS), a TETRA packet data service, a short message service (SMS), general packet radio service (GPRS), a text messaging service or a wireless data link service. The DIIGW also implements at least one virtual mobile station (161) that corresponds to a real mobile station that has migrated to a visited wireless communication network, and can allow its corresponding real mobile station to communicate with its home wireless communication network.</p> |
