(2) audio call Establishing process
As shown in Figure 3, process step is as follows for audio call Establishing process:
A. eat dishes without rice or wine to access;
B. terminal sends call setup request message;
C. called number is extracted in base station, carries out number analysis, checks whether called number is the termination number that has been registered in this base station, if so, sends call setup response message to terminal, enters steps d.If Query Result is empty, illustrate that terminal called is not under this base station, call flow finishes;
D-g. generation beep-page message in base station carries out broadcast transmission from broadcast channel, and terminal is initiated the access of eating dishes without rice or wine after receiving paging, base stations transmit call foundation request after access, and terminal is returned to call setup response.Enter call setup state;
H. after terminal called access, send ALERTING message;
I. base station forwards ALERTING message to calling terminal, and calling terminal is received after ALERTING message, playing RBT voluntarily;
J. terminal called off-hook, sends session setup request message;
K. message conversion is carried out in base station, sends session setup request message;
L. calling terminal sends call and sets up response message;
M. message conversion is carried out in base station, sends call and sets up response message;
Afterwards, session establishment completes, and calling and called terminal enters call.
(3) audio call discharges flow process
Audio call discharges flow process as shown in Figure 4, calls out and discharges in flow process, and receive after calling releasing request base station, generates call release message to corresponding terminal called.
Embodiment bis-
As shown in Figure 5, wherein base station has also increased a ticket task module except having increased a speech business module to the network architecture of the present embodiment two, for solving message registration under base station fault reduction pattern, the problem of losing occurs.Base station starts ticket task module after entering fail soft mode, and in the time having audio call to occur, speech business module records current sessions state, sends message informing to ticket task module, generates ticket by ticket task, exists local; Link-recovery, base station enters after normal mode of operation, and ticket is uploaded to Record Bill Server.
Because local call is only supported in base station under fail soft mode, so a lot of attributes do not need in standard ticket, the present embodiment has defined the format of billing being exclusively used under fail soft mode, ticket content only contains numbers of calling and called parties, type of call, beginning end time, air time, takies the fields such as duration, is the simplest subset of standard ticket.Can reduce like this base station and process complexity, reduce CDR file size.
Below with base station A under fail soft mode, communication service occurs for terminal B and C is example, concrete steps are as follows:
1) base station A and network side link down, work in fail soft mode;
2) terminal B dial-up C;
3) base station A speech business module is received the setup requests of B, sends notice to ticket task module, and ticket task module starts ticket writing and generates;
4), in communication process, ticket task module, according to talking state machine ticketed call stage, the duration of call, generates this ticket writing;
5), after having conversed, this ticket writing is write CDR file by base station.
Speech business ticket is responsible for safeguarding in base station, and ticket is stored in local file storage area; If memory block is full, base station, still in fail soft state, is used new file to cover old file simultaneously.
