A wireless network that provides a packet data call connection between a source mobile station (MS) and a destination mobile station (MS) in a coverage area of the wireless network. The wireless network comprises a first base station that wirelessly communicates with the source mobile station, a second base station that wirelessly communicates with the destination mobile station, and a mobile switching center that connecting the first and second base stations. The first base station receives a first message from the source mobile station requesting a MS-MS packet data call connection to the destination mobile station.
