Problems solved by technology

[0020] The initial value of the above method (t 1 , t 2 ) usually adopts a fixed value, lacks correction, and often affects the inverse calculation efficiency due to inappropriate selection of the initial value, occupying a large amount of resources in the billing system; although the price function is diverse, it can still be described as a series of broken lines, dichotomy It is a fixed search algorithm, which does not make full use of the linear characteristics of these polylines and lacks flexibility

Embodiment 1

[0048] The historical back-calculation results in the billing system have a guiding effect on the subsequent back-calculation. This embodiment starts from this point and uses the historical back-calculation results to correct the initial value set during the back-calculation process.

[0049] Save the historical inverse calculation results in the billing system, specifically, create an initial value correction table for each price function, the table records are composed of a series of , and the table can be sorted according to the balance, It can realize the function of quick search. As shown in Table 1, it is an example of a correction table for a certain price function:

Embodiment 2

[0101] On the basis of the first embodiment, the second embodiment modifies the scaling factor λ by constructing a historical iterative experience table.

[0102] Establish a scale conversion factor experience table for each price function, which is composed of ; select the scale conversion factor in the average number of iterations record as The scaling factor empirical value. As shown in Table 2, it is an empirical table of scaling factors for a certain price function (for example, the price function corresponding to "local call"):

Embodiment 3

[0108] Unlike Embodiment 1 and Embodiment 2, which use the iterative method to solve the inverse calculation, the inverse calculation function in this embodiment is based on the chord method to solve the usage; the correction table is also used to correct the initial value of the inverse calculation.

Abstract

This invention discloses one charge system reverse formula method to get user remaining service volume, which comprises the following steps: aligning first use volume to user and computing first volume relative first charge; when the user remaining volume is less than first charge through correction list or proportion mapping type to correct first volume; using corrected volume as reverse function initial values to solute user remaining value in gradually drawing type. This invention also discloses one charge system to find relative service volume.

Description

technical field [0001] The invention relates to the technical field of telecommunication billing, in particular to an inverse calculation method for inversely calculating service availability by using a balance in a billing system and a billing system. Background technique [0002] In the prepayment system in the telecommunications field, users need to pre-purchase a certain amount of service or pre-store a certain amount of consumption. The workflow of the prepaid system includes the following steps: [0003] 1. The user purchases the prepaid product of the operator; [0004] 2. The user pre-deposits a certain amount (recharge); [0005] 3. The user requests the operator to provide the purchased service; [0006] 4. The operator's billing system calculates the available amount of services according to the available balance of the user account, withholds the balance, and provides the result to the call control system; [0007] 5. If the service is unavailable, terminate ...
