When Fig. 2 B showed Bluetooth terminal by the wireless terminal accessing device access fixed network, the speech business flow process from Bluetooth terminal side direction PSTN network side makes a call may further comprise the steps:
Step S310, the user makes a call from the Bluetooth terminal dialing, Bluetooth terminal sends call request by Bluetooth protocol to access device, and the information such as address of transmission called number and this Bluetooth terminal, calling number can be sent by Bluetooth terminal, is perhaps obtained according to the terminal address of preserving and the relation of telephone number by access device;
Step S320, after access device received call request, the called number in the preservation message and the address of this Bluetooth terminal generated off hook signal, send to the PSTN network through analog line, wait for the response of PSTN net;
After step S330, access device detect the dialing sound of PSTN net through sending on the subscribers feeder, send called number to the PSTN network, calling number can send to the PSTN net together with called number, and the PSTN side not necessarily needs;
Step S340 after the PSTN net receives called number, analyzes number, finds the called subscriber, and to called subscriber's ring, transmits ring-back tone or voice to access device then;
Step S350, access device reverses by the signal polarity that its interface circuit detects on the subscribers feeder, perhaps, it is back to off hook signal to detect ring-back tone termination or voice termination etc., represent called off-hook, then connect the two-way telephone circuit between network side and Bluetooth terminal, begin conversation.
When Fig. 2 C shows Bluetooth terminal by the wireless terminal accessing device access fixed network, initiate the flow process that voice discharge from the Bluetooth terminal side:
Step S410, under talking state, dispose procedure is initiated in Bluetooth terminal user on-hook, and Bluetooth terminal sends release message by Bluetooth protocol to access device;
After step S420, access device receive the release request of Bluetooth terminal, generate on-hook signal, send, after PSTN detects this on-hook signal by its interface circuit, carry out the release processing procedure through analog subscriber alignment PSTN network;
Step S430 accesses terminal and initiates to discharge request to Bluetooth terminal, and Bluetooth terminal discharges wireless channel, returns Release complete to access device after finishing, and access device and Bluetooth terminal are all got back to idle condition.
When Fig. 2 D shows Bluetooth terminal by the wireless terminal accessing device access fixed network, initiate the flow process that voice discharge from the PSTN network side:
Step S510, under talking state, access device detects the busy-back signal of coming from subscribers feeder, and expression PSTN side has started dispose procedure;
Step S520, access device initiates to discharge request to Bluetooth terminal, simultaneously, produces on-hook signal and sends on subscribers feeder, tells PSTN side user on-hook;
Step S530, Bluetooth terminal discharges wireless channel, returns Release complete to access device after finishing, and Bluetooth gateway and Bluetooth terminal are all got back to idle condition.
The handling process of fixed net short message.
When Fig. 3 A showed Bluetooth terminal by the wireless terminal accessing device access fixed network, Bluetooth terminal was uploaded the flow process of fixed net short message message:
Step S610, Bluetooth terminal initiate short message in the Bluetooth protocol mode to access device and call out, and carry dialing number information;
After step S620, access device receive this call message, send upload request to the short message service center of network side, carry dialing number information with FSK or DTMF mode;
Step S630, request is received by short message service center, after the affirmation calling subscriber is effective, prepares to receive and uploads information, and send out acknowledge message in the FSK mode to access device;
After step S640, access device receive the affirmation message of network side, pass through, can send SMS message by Bluetooth protocol notice Bluetooth terminal identity validation;
Step S650, Bluetooth terminal sends SMS message to access device by Bluetooth protocol, after access device is received short message, is converted to FSK or dtmf signal, and the short message service center to network side sends SMS message through subscribers feeder, and short message service center receives and the storage short message,
Step S670, short message service center sends release message to access device, after access device is received, the on-hook signal that the analog subscriber phone sends to network side, the resource of releasing network side, and, finish the dispose procedure of channel to Bluetooth terminal transmission release message.
When Fig. 5 B showed Bluetooth terminal by the wireless terminal accessing device access fixed network, the flow process of Bluetooth terminal program request fixed net short message message may further comprise the steps:
Step S710, Bluetooth terminal makes a call to access device in the Bluetooth protocol mode, carries caller information;
