대표청구항 ▼

1. A method of operating a plurality of base stations in Code Division Multiple Access macrodiversity mode to communicate a message to a mobile station via an air interface, comprising:attempting to communicate the message to the base stations via a packet network; determining, at one of the base stations, whether the message is corrupted after the attempted communication from packet network to the one base station; if the message is not successfully communicated by the packet network to one of the base stations, refraining from communicating any message from the one base station to the mobile station; and if the message is successfully communicated by the packet network to the one base station, communicating the message from the one base station to the mobile station via the air interface using Code Division Multiple Access.
