After step 303, Femto module 36 receive IP packet, the header packet information according to packet judges this packet, if 3G signal is just transferred to the FemtoGW module 31 in GW subsystem 22 by Iuh interface; WiFi signal if not 3G signal, just the IP data packet transmission received to WLANAP module 35, by it by IP data packet transmission to the WLANAC module 32 in GW subsystem.
It should be noted that, Femto module after receiving IP packet, except the classification of decision data bag, also can according to the situation of current network, the carrying of the such as network bandwidth, carries out the Service control strategy of data packet transmission.Method is as follows:
FAP subsystem 23, when network bandwidth occupancy reaches threshold value, judges that the signal received is 3G signal or WiFi signal;
If what receive is 3G signal, then this 3G signal is sent to GW subsystem 22;
If what receive is WiFi signal, then indicates wlan subsystem 24 to suspend and send WiFi signal to GW subsystem 22, when waiting for network bandwidth occupancy lower than threshold value, then indicate wlan subsystem 24 to send this WiFi signal to GW subsystem 22.
Step 304, Femto module 36 are when the IP packet judging to receive is the packet of 3G signal, and judge that this packet is the packet of speech business or the packet of data service further, its judgment mode is:
If the address of gateway safe to carry in the packet header of IP packet, represent that this IP packet is the packet of the speech business of 3G signal; If what carry in the packet header of IP packet is destination address, represent that this IP packet is the packet of the data service of 3G signal.
Step 305, GW subsystem 22 are by the packet of Iuh interface to the speech business of the 3G signal sent by Femto module 36.
Step 306, FemtoAAA module 33 packet to the speech business of the 3G signal received carries out authentication, determines whether the terminal accessed is legal Femto terminal; The packet of FemtoHLR module 34 to the speech business of the 3G signal of access carries out registration management and end message management.
Step 307, by the packet of the speech business of legal 3G signal being transferred to core net circuit domain by Iu-CS interface after the confirmation of GW subsystem 22.
Step 308, GW subsystem 22 are by the packet of Iuh interface to the data service of the 3G signal sent by Femto module 36.
Step 309, FemtoAAA module 33 packet to the data service of the 3G signal received carries out authentication, determines whether the terminal accessed is legal Femto terminal; The packet of FemtoHLR module 34 to the data service of the 3G signal of access carries out registration management and end message management.
Step 310, by the packet of the data service of legal 3G signal being transferred to core network packet-domain by Iu-PS interface after the confirmation of GW subsystem 22.
Step 311, GW subsystem 22, are managed this IP packet to the IP packet sent by WLANAP module 35 by WLANAC module 32 by Iuh interface, such as format transformation, encryption, carry out certification etc. to the terminal sending IP packet.After determining the information of IP packet, send to FemtoGW module 31, transfer to the Internet 28 by FemtoGW.
Be more than the uplink process of the present embodiment seven, its downlink transmission process is its inverse process.
