The request of face information and transmission on log on side user plane resource then carries RTP moulds by the generation of BSSAP modules again
Call proceeding (Call Proceeding) signaling for the network side user information that block is returned, by the call proceeding signaling
2G terminals are sent to by 2G base stations.Meanwhile called subscriber is judged for 3G terminal by the Message Processing modular converter of Convergence gateway, and
The call request message (Paging) of a RANAP form is constructed, the call request message is encoded by RANAP modules,
The call request after encoding is sent to 3G terminal by NodeB.NodeB sends exhaling from 3G terminal to Convergence gateway
Response (Paging Response) is cried, shows that 3G terminal receives this calling.Convergence gateway is receiving the signaling of the call
Afterwards, message (Setup) is established according to the call one RANAP form of construction received by RANAP modules, this is established
Message is issued to 3G terminal by NodeB.After the confirming call (Call Confirm) from 3G terminal is received, fusion
The RANAP modules of gateway obtain called base station side and network side user relevant information by the interaction with RTP modules.When melting
After conjunction gateway receives wake-up (Alerting) message for 3G network communication from 3G terminal, by Message Processing modulus of conversion
Block analyzes and processes call flow, and the wakeup message of the RANAP forms received is converted into BSSAP forms, and by BSSAP moulds
Block carries out message coding to the wakeup message, and the wakeup message after encoding is sent to 2G terminals by 2G base stations, is held at this time
The user for having 2G terminals can be heard just in ring tone.
When holding the user of 3G terminal and pressing Answer Key, 3G terminal sends connection (Connect) message, and NodeB connects this
It connects message and is sent to Convergence gateway.Convergence gateway passes sequentially through RANAP modules, Message Processing modular converter and BSSAP modules will
The connection message is converted into connection (Connect) message available for 2G networks and sends it to 2G terminals.2G terminals receive
To after the connection message, connection response (Connect Ack) message is sent to Convergence gateway by 2G base stations.Convergence gateway is connecing
After receiving the connection response message, pass sequentially through BSSAP modules, Message Processing modular converter and RANAP modules and ring the connection
Connection response (Connect Ack) message available for 3G network should be converted to and send it to 3G terminal.3G terminal receives
To after the connection response message, call is established, 2G user and 3G subscription can by the RTP module transfers data in Convergence gateway with
It converses；
It assuming that after end of conversation, is hung up first by 2G user, then sends and disconnect from 2G terminals to 2G base stations
(Disconnect) message, and pass through 2G base stations and the disconnection message is sent to Convergence gateway.Convergence gateway still passes through BSSAP
The disconnection message is converted to the disconnection available for 3G network by module, Message Processing modular converter and RANAP modules
(Disconnect) message, and pass through NodeB and be sent to 3G terminal.After 3G terminal receives message, send releasing (Release) and disappear
Breath.Convergence gateway is then disappeared the releasing from NodeB by RANAP modules, Message Processing modular converter and BSSAP modules
Breath is converted to releasing (Release) message available for 2G networks, and the releasing message is sent to 2G terminals by 2G base stations.
2G terminals finish (Release Complete) message after the releasing message is received, by releasing and are sent to Convergence gateway.Merge net
It closes the releasing is finished message to be converted to and finishes (Release Complete) message available for the releasing of 3G network, be sent to 3G ends
End.Meanwhile the BSSAP modules in Convergence gateway notify RTP modules release 2G networks to be used with 3G network respectively with RANAP modules
Associated user face resource, completion of then taking out stitches.
It can be seen from above-described embodiment that 2G and 3G message can be completed at Convergence gateway using the method for the present invention
Conversion, without 2G and 3G terminal is made to be respectively connected to 2G and 3G core nets, reduces network construction and maintenance cost.
