A kind of mobile intelligent net charging method

Technical field

The present invention relates to mobile intelligent net, refer to the method that a kind of mobile intelligent net realization is accurately chargeed especially.

Background technology

Mobile intelligent net is to introduce the intelligent network functional entity in the mobile network, to finish a kind of network to the Based Intelligent Control of mobile calls.It is existing mobile network and the combining of intelligent network.If transform the switching center of mobile network as the SSP Service Switching Point, the mobile network of bottom is linked to each other with the intelligent network (SCP, SMP, SCE, SMAP etc.) of high level, separate realization thereby will move exchange with professional, just formed mobile intelligent net.

Support by means of No.7 signaling network and large-scale centralized formula database, mobile intelligent net is separated the function of exchange and the controlled function of network, originally the network intelligence that was arranged in each end office switch in the telephone network is focused on the functional part of newly establishing--on the Service Control Point of intelligent network be made up of medium-mini computer, and original switch is only finished the basic function that continues.

Mobile intelligent net generally is made up of SSP (Service Switching Point), SCP (service control point), IP (ip intelligent peripherals), SMS (business management system), SCE several parts such as (service creation environments).SSP is the tie point that connects existing mobile network and intelligent network, and the function that inserts intelligent network function collection is provided.SCP is the core component of intelligent network, its storaging user data and service logic.Major function is to receive Query Information and the Query Database that SSP sends here, carries out various decodings; Simultaneously, SCP can start different service logics according to the call event of offering on the SSP, sends the calling control command according to service logic to corresponding SSP, thereby realizes various intelligent calls.Ip intelligent peripherals is a special resource of assisting to finish IN service.Usually have various phonetic functions, as phonetic synthesis, the playback notice receives DTMF pulsing, carries out speech recognition or the like.SMS is made up of computer system, generally possesses 5 kinds of functions, i.e. service logic management, Service Data Management, user data management, professional monitoring and traffic management.The function of SCE is the new service logic of demand generation according to the client.The general structure of mobile intelligent net system as shown in Figure 1.

The charging way that present mobile intelligent net system provides mainly contains three kinds:

Charge by metering: this is the most general charging way, and telephone expenses are relevant with service time, and base rate is by calling and called number and professional decision.

One-off charge: this charging way is mainly used in system and uses when the user provides in due order service, and as revising user profile such as password etc., expense is relevant with the service of use, receives fixing expense each time, and has nothing to do with the calling and called number.

Nontraffic sensitive: nontraffic sensitive charges also irrelevant with the calling and called number, but ultimate cost is relevant with service time, and this charging way is mainly used in system when the user provides service between not timing, as common information inquiry, business such as tin song.

The mobile intelligent net system also can provide surcharge and after charge flexibly, comprising:

Basic supplementary cost: act on all business in the system of running on.

Intelligence additional cost: be directed to some professional imposition ofs surcharge.

User's additional cost of being correlated with: at some service-user imposition ofs surcharge.

The discount processing mode of mobile intelligent net system comprises:

Daily discount: give a discount during some time period of regulation every day.

Week discount: give a discount when being defined in some time period of some day in each week.

Festivals or holidays discount: stipulate to give a discount in certain time periods of a certain festivals or holidays.

User's discount: can discount be set specially for special professional or special user, give a discount when surpassing certain limit, or the virtual private on-net call give a discount as user's moon expense.

Mobile intelligent net system rate is provided with:

The mobile intelligent net system can be provided with rate flexibly according to calling and called number exhaustive division, mainly is classified as follows:

Local call; National distance; International long-distance; Charge in the Hong Kong, Macao and Taiwan; Move and charge.

The solution of mobile intelligent net data service at present by the flow information that SGSN and GGSN surf the Net to the SCP report of user, to SCP report content charge information, realizes charge on traffic and content charging by WAPGW respectively as shown in Figure 2; Simultaneously for content charging, the data traffic that takes place in SCP this content charging process according to the WAPGW report unifiedly deducts the flow that this content charging takes place from the total flow of SGSN, GGSN report, reaches this type of business only by the purpose of content charging.

The shortcoming of prior art one:

Existing mobile intelligent net data service billing method is to gather the flow charge information from SGSN, GGSN, gathers the related content charge information from WAPGW, and calculated flow rate expense and content fee are used respectively.Yet, ask for something is only pressed the business of content charging, such as the MMS business, requirement is chargeed according to the bar number of transmitting-receiving MMS, receive smacker such as MMS message of every transmission, after having received the expense of this yuan, just should not collect traffic fee has again used, in this case, WAPGW need notify the SCP module of being responsible for chargeing that the traffic fee that this business has collected is moved back expense, return the traffic fee usefulness of having collected, quite complicated but this method of moving back expense not only operates afterwards, and have coarse fatal problem of chargeing.With Fig. 3 is example, and we illustrate coarse problem of deducting fees.As noted before, often there are various discounts in the telecommunication service, modal is the time period discount, such as in Fig. 3, traffic fee 5 foldings after the regulation 10:00 in evening, user's a content charging business lasts till 10:10PM from 9:50PM always, the flow of 100K has taken place, after 10:10PM finishes this transaction, the functional entity WAP GW that is responsible for the content charging report finds that this is a transaction of only chargeing by content, therefore notify the SCP module of being responsible for deducting fees, need in the deduction transaction this time by SGSN, the traffic fee that GGSN reports is up used, at this moment just have a problem, WAPGW and do not know 100K flow in this transaction which occur in 10:00PM actually before, which takes place after 10:00PM, can only be according to time period estimated flow section, this estimation is coarse, may collect expense less, causes the loss of operator; Also may overcharge expense, cause user's loss.
