Abstract
The method includes adding a "delay analysis needed" zone bit in analysis result of number analysing, sending the number to number analysing module for analysis after it having been received by exchanger service module which judges whether "delay analysis needed" flag is set or not, carrying on process separately for different events received by the exchanger, judging whether minimum number length required by out office route or searching for the called user is realized or not, rearching the called user or out office route and judging whether searching for the called user or out office route is successful or not.
Description
Technical field
The present invention relates to the communication technology, the program controlled switch technology in being specifically related to communicate by letter in particular, relates to a kind of method that realizes delayed connection calling and called user in the stored-program control exchange.
Background technology
Present stored-program control exchange although have powerful number analysis function, still can't be handled for the situation of the called number with overlapping number analysis prefix.Such as for a certain telephone office, the shortcode of 168 corresponding office directions 1, and the shortcode of 1681 corresponding office directions two, or the like increase number successively in the back, represent different office directions, if user's this moment wants to dial on 1681 to office direction 2, but when switch is received 1,6,8 three number, just obtained analysis result, analysis result is last shortcode to office direction 1, begins to look for the route that goes to office direction 1, thereby disagrees with calling subscriber's wish, therefore for this situation, former switching equipment can't carry out differentiating and processing.
Summary of the invention
The technical problem to be solved in the present invention is to realize by revising call treatment control flow and number analysis control flow, number to some overlapping analysis prefix carries out delay analysis, propose a kind of delayed connection method of programme-controlled exchange, be routed to the function of different office directions with the number that has overlapping analysis prefix more than realizing; The increase of this function has also enlarged the scope of application of the number resource of operator simultaneously.
The delayed connection method of a kind of programme-controlled exchange of the present invention, the step of realization is as follows:
The first step, in the analysis result of number analysis, increase a flag bit: " needing delay analysis ", when overlapping analysis prefix is analyzed, this sign put get final product, still with the previous example example: for top 168,1681 and 16811, because 168 and 1681 are overlapping prefix, so when these two prefixes are carried out number analysis, this sign must be put;
Second step, receive number when the exchange service processing module, to deliver to the number analysis module and analyze, and the result is returned to Service Processing Module, Service Processing Module is judged, if there is not analysis result, is then continued to collect the digits; If analysis result is a spacing, then change the processing of the 7th step over to; If any analysis result and be not spacing, then changed for the 3rd step over to handle.
The 3rd step, Service Processing Module judges among the number analysis result whether " needing delay analysis " sign is set, if be not provided with, then continue to collect the digits, (minimum number length when the called number of receiving reaches minimum number length, be meant the minimum length that can look for called subscriber or outgoing route), changed for the 5th step over to look for called subscriber or outgoing route to handle;
If be provided with " needing delay analysis " sign in the analysis result, then expression need be carried out delay analysis, and this moment, professional control program was provided with a delayed connection timer, entered the delay Number Receiving Status;
In the 4th step, switch is handled respectively by the difference of reception incident; If do not receive any number information, wait for collecting the digits overtimely that this situation shows that subscriber dialing finishes, changed for the 5th step over to handle; If receive number, judge at first then whether this number is " # ", if " # ", show that subscriber dialing finishes, changed for the 6th step over to handle, look for called subscriber or outgoing route; If the number of receiving, turned back to for second step for " # " and handles;
The 5th the step, judge whether to reach and look for called subscriber or the required minimum number length of outgoing route, if do not reach, then change over to second the step continue to collect the digits;
The 6th step, look for called subscriber or outgoing route, judge and whether successfully to look for called subscriber or outgoing route, if the residue call flow is finished in success; If failure changeed for the 7th step;
In the 7th step, failure is handled: send the failure sound to the calling subscriber, point out this calling to set up.
The beneficial effect that uses delay analysis connecting method of the present invention is tangible, can use number resource more fully effectively, such as can be to analyzing such as 168,1681,16811 numbers with overlapping analysis prefix, and be routed to different office directions thus, thereby enlarged number resource.
Description of drawings
Accompanying drawing 1 is the concrete process chart of the call processing method of indication of the present invention.
Accompanying drawing 2 is the flow chart of number delay analysis module of the present invention.
Embodiment
Below in conjunction with accompanying drawing, and delayed connection method of the present invention is elaborated by embodiment.
Dialing 1681 with the user is example, introduces the realization of delayed connection method in detail, in this agreement 168 to office direction 1,1681 to office direction 2,16811 to office direction 3.Therefore, at first increase in number analysis numeral ' 168 ' ' 1681 ' ' 16811 ' is analyzed, ' 168 ' analyzes to the outbound call to office direction 1, needs delay analysis; ' 1681 ' analyzes to arriving the outbound call of office direction 2, needs delay analysis; ' 16811 ' analyzes to arriving the outbound call of office direction 3, does not need delay analysis.Idiographic flow is divided into following five steps:
1, as shown in Figure 1, at first will postpone on the mark position, user's off-hook is listened dialing tone, begin to dial called number then, before the user was dialing 1,6,8 three numeral, Service Processing Module passed to the number analysis module by the number analysis inlet with called number, is checked numbers by the number analysis module and analyzes, analysis is come to nothing, and Service Processing Module is in Number Receiving Status always.
After the user was received 1,6,8 three numeral, Service Processing Module passed to the number analysis module with 1,6,8 three numeral by the number analysis inlet.
2, number analysis module flow chart carries out following analysis as shown in Figure 2:
At first numeral 1 is analyzed, analysis is come to nothing, and subsequently numeral 1,6 is analyzed, and analysis is come to nothing; Check numbers then and 1,6,8 analyze, analyzing has the result, judges whether subsequently to check numbers 1,6,8 to carry out delay analysis, as not needing delay analysis, withdraws from the number analysis module, and the number analysis result is returned to Service Processing Module.In this example, the number analysis result is delay analysis, the number analysis module is taken off an item sign indicating number and is analyzed, because the user has only dialed three item sign indicating numbers at present, no next bit number is analyzed, this moment, the number analysis module returned to Service Processing Module with the number analysis result, and with the delay analysis flag set (expression needs) of Service Processing Module, got back to the professional control flow of call treatment then;
Service Processing Module is provided with the delayed connection timer according to the delay analysis sign, enters the delay Number Receiving Status, waits for that the user dials the next bit number.
3, stop dialing as the user, delayed connection timer expiry, Service Processing Module then change step 4 (stop key as the user, then Service Processing Module is routed to office direction 1 by 168 to the user) in this example.As receive the next bit number, and then remove the timer that continues of delaying time, and judge whether this number is ' # ', as representing then that for ' # ' called number has collected, Service Processing Module changes step 5 over to.As receive and then enter the number analysis module by other numbers, check numbers again and analyze.The user receives number ' 1 ' subsequently in this example, and Service Processing Module will ' 1681 ' passes to the number analysis module, this with last time number analysis different be that the analysis number is ' 1681 '.The analytic process of front three ' 168 ' is identical with the front, and analysis result is for there being analysis result, and needs delay analysis, then gets next bit analysis.Analysis result is still for there being analysis result, and need carry out delay analysis.Service Processing Module is provided with the delayed connection timer again according to the delay analysis sign, enters to postpone number state of sending out; Because user's this moment button no longer, delayed connection timer expiry, Service Processing Module then change step 4 over to.
Step 4: Service Processing Module is after obtaining analysis result, judge whether the user reaches and look for called subscriber's required number length, as not reaching, then keep Number Receiving Status, up to collecting the required number length of called subscriber and changing step 5 over to, called number collects in this example, and Service Processing Module changes step 5 over to.
Step 5: as collecting called number, then look for called subscriber or route according to the number of receiving, as search user or route success, then call setup success is then sent the failure suggestion voice to caller as failure.In this example, as continue successfully, Service Processing Module will be routed to office direction 2 with the user according to number ' 1681 '.As failure, then connect the failure suggestion voice to the calling subscriber.
Below the narration user dials ' 168x ', x is 0,2 ..., 9 non-1 digital the time, flow process is as follows:
Step 1, step 2, step 4 and step 5 are identical with the front.
Only 3 different in steps with the front, after the user has dialled ' 168 ', dialled one non-1 button (such as dialling 2), then Service Processing Module is removed the timer that continues of delaying time, to ' 1682 ' and pass to the number analysis module, check numbers again by the number analysis module and analyze.Because not to ' 1682 ' data of doing number analysis, so analysis result is in this example: do not have analysis result, according to shown in Figure 2, the number analysis module is returned Service Processing Module.Service Processing Module judgement number analysis is come to nothing, and is in the delay Number Receiving Status simultaneously again.Then, enter step 4, judge promptly whether the user reaches to look for called required number length immediately according to ' 168 ' analysis result, as not reaching, then keep Number Receiving Status, look for the required number length of called subscriber and change step 5 over to, look for called subscriber or outgoing route up to collecting.
