FMC architecture for CDMA network

摘要

A method and apparatus are provided for connecting a mobile device to a subscriber access network, such as 3G network over an untrusted network, such as a wireless local area network (WLAN). SIP signaling is performed to authenticate and establish a connection to the subscriber access network. A unique identifier may be assigned to the mobile device for transmitting data to and receiving data from the subscriber access network.

主权项

1. A method for connecting one or more mobile devices to a subscriber access network over an untrusted network, comprising:
performing, by a session initiation protocol (SIP) gateway (GW), SIP-based signaling to authenticate and establish a point-to-point protocol (PPP) connection to the subscriber access network from a packet data serving node (PDSN) of the subscriber access network with each of the one or more mobile devices, wherein performing the SIP-based signaling further comprises establishing an A10 link between the SIP GW and the PDSN to perform access authentication; performing, by the SIP GW, High-Level Data Link Control (HDLC) framing and unframing; assigning a unique identifier to each of the one or more mobile devices for transmitting and receiving data to and from the subscriber access network over the untrusted network; maintaining an A10 mapping table of the unique identifier to an appropriate A10 link; and utilizing, by the SIP GW, the A10 mapping to connect to each of the one or more mobile devices and to forward data coming from each of the one or more mobile devices over the untrusted network to the PDSN via the appropriate A10 link.
