Main call number analysis method for program controlled exchanger

Technical field

The present invention relates to a kind of stored-program control exchange number analysis method, more particularly, relate to a kind of main call number analysis method for program controlled exchanger.

Background technology

Along with the development of telecommunications industry, telecommunications network shows following some variation tendency:

(1) existing P STN/ISDN network planning mould constantly enlarges;

(2) increasing operator adds telecom operation;

(3) GSM net, CDMA net, IP telephony network etc. build up not broken hair exhibition successively;

(4) various new business constantly provide.

For guaranteeing interconnecting and OPTIMAL ALLOCATION OF RESOURCES of whole telecommunications network, press at switch (particularly between the different operators, tandem exchange between the dissimilar nets and gateway exchange) on a kind of effective means are provided, it can be according to calling subscriber's attribute (as operator, the zone of user's calling, user's classification etc.) finish functions such as Route Selection, charging.

Existing function mode has two kinds: a kind of is that caller attributes is distinguished according to the office direction of incoming call by tandem exchange, but this method is roughly distinguished the attribute of calling number only, invalid for widely used sociable relaying.For example: for the gateway exchange of local network, the calling calling subscriber always of Local Exchange is local fixedly local telephone network, the calling caller that mobile office direction is come is the mobile subscriber, though the angle that the high rate of collateral security are called out is considered, the calling that switch can be made as the office direction incoming call of moving office provides higher routing priority, but toll switch calling always, the incoming call of getting on well with others of long-distance mobile subscriber and fixed-line subscriber, adopt this method then can't distinguish, and also can't provide different services for it; Another kind is the service that provides in tandem exchange at different user, promptly in switch, may set up attribute list by the user of this switch for each, when calling out incoming call, inquire about its user property according to its calling number, again according to the authority of this user property, type is determined its exhalation type, yet on China's telecommunications network several hundred million user is arranged at present, if for each user sets up database, system cost is sharply risen, and all in attribute database, retrieve for each calling, operating efficiency is very low, so this method only is applicable to less system, does not have practical value substantially for large-scale tandem exchange.

Summary of the invention

The object of the present invention is to provide a kind of program control main call number analysis method, can draw its association attributes fast and effectively according to calling subscriber's number in tandem exchange, as: affiliated operator; The region; Type (move, fix and the IP user); The Freight Basis of this calling; This is called out and adopts new business etc., thereby finishes functions such as Route Selection, charging, and the data retrieval amount is little, high efficiency.

Program control main call number analysis method provided by the present invention comprises following steps at least: according to different relaying situations, make up the calling number parsing tree respectively on the office data of tandem exchange; Carry out at needs on the incoming office direction of calling number analysis, unconditionally require the other side office to send calling number; After calling number receives fully, carry out the calling number analysis; Calling number is sent into respectively in the number analysis device in the calling number parsing tree, drawn its corresponding calling subscriber's attribute; In the calling number analysis result, draw the called number parsing tree that called number is suitable for simultaneously, be used for called number is analyzed; Called number is sent into the called number analyzer, in the called number analyzer, draw the attribute information of called number; The analysis result of comprehensive calling number draws the rate and the priority of this calling; With the analysis result of called number calling number attribute information, select corresponding outgoing route, or send different failure notification sounds in conjunction with this user.
