Internet protocol telephony for a mobile station on a packet data channel |
摘要 |
A method and apparatus are provided for effectuating voice communication between a mobile station and a mobile radio network. A gateway to the mobile radio network receives an incoming voice call for a destination mobile station and accesses information pertaining the status and location of the destination mobile station. A determination is made as to whether the destination mobile station is capable of operation in a voice mode using circuit-switched communications across a traffic channel. If the destination mobile station is operable in the voice mode, a circuit-switched communication on a traffic channel is established between the mobile radio network and the destination mobile station. Otherwise, the incoming voice call is routed to a voice gateway which converts the voice call to data packets and routes the data packets to the mobile station across an Internet Protocol communication network to a packet gateway of the mobile radio network. The packet gateway routes the call across a packet data channel of the mobile radio network to the destination mobile station using a packet data service.
