On the other hand, accounting server is used for chargeing according to the call signaling from signalling processing equipment at least in part.Specifically, if signalling processing equipment all duplicates and is forwarded to accounting server with whole call signalings of signaling link transmission, then accounting server need sort these call signalings according to predefined strategy, selects and the relevant call signaling that charges, and charges in view of the above.If signalling processing equipment sorts according to the call signaling of predefined strategy to the signaling link transmission, then directly chargeing in view of the above gets final product.
Above the formation of the exchanger metering system of user's intra-office of present embodiment conversation is explained.Further specify the dynamic duty process of this exchanger metering system below.
When LS initiated to point to the calling of local exchange, call signaling pointed to signalling processing equipment through the out-trunk from loop circuit, and signalling processing equipment carries out switching of OPC and DPC to this call signaling, then call signaling is beamed back LS, connects the local subscriber.In this case, the data that need on the LS to do are the local called callings at local exchange initiated of LS, point to signalling processing equipment by encircling the out-trunk route certainly, and point to local in the calling of going on the relaying that encircles certainly.
Meanwhile, signalling processing equipment is being received local switch, promptly behind the call signaling that end office (EO) sends, part call signaling or whole call signaling is duplicated, and be transmitted to accounting server.As mentioned above, if the part call signaling is duplicated, then signalling processing equipment needs according to the predefined charging policy of operator, the call signaling of being received is sorted, select with charge relevant, just, again accounting server is duplicated and be transmitted to these relevant signalings to the responsive call signaling that charges.The benefit of Chu Liing has been to reduce the letter sorting burden of accounting server like this.
After this, accounting server charges according to the call signaling from signalling processing equipment.If what receive is to sort through signalling processing equipment,, then directly charge with the relevant signaling of chargeing.On the other hand, if what receive is the whole call signalings that do not sort through signalling processing equipment, then accounting server is according to the predefined charging policy of operator, comprise initial address message (InitialAddress Message to receiving, be called for short " IAM "), message (Address Complete Message is finished in the address, be called for short " ACM "), response message (Answer Message, be called for short " ANM "), REL, (Release Complete is finished in release, abbreviation " RLC ") message etc. sorts at interior call signaling, calculate the duration of call according to what choose with the relevant signaling of chargeing, and produce ticket.It is pointed out that according to principle of the present invention accounting server can in very large range oneself define charging policy, even cooperates miscellaneous equipment to accomplish real time billing or realize other call charge service.
This shows, the difference of second embodiment and first embodiment is, first embodiment is applied to station-to-station call, second embodiment is applied to the intra-office conversation, and switch self carries out circuit from ring, signalling processing equipment is serially connected in the signaling link of ring, and is transmitted to accounting server after duplicating with the call signaling of receiving is all or part of, and accounting server charges in view of the above.Present embodiment can be realized chargeing and the separating of business equally, thereby unified billing interface can be provided.In addition, owing to signalling processing equipment is serially connected in the signaling link, so can not omit any call signaling relevant with charging.And, if call signaling is carried out in advance letter sorting, then can further reduce the burden of accounting server by signalling processing equipment, reduce the traffic between signalling processing equipment and the accounting server.
The invention allows for a kind of switch charging method, can realize by the exchanger metering system of above-mentioned first and second embodiment.In this switch charging method, require between two switches in the charge system on the signaling link or single switch from encircle be provided with on the signaling link as first or second embodiment described in signalling processing equipment.
