Description

Method and device for converting graphical business process into business script

The present invention relates to the field of telecommunications business process design, and more particularly to a method and apparatus for converting a graphical business process into a business script. Background technique

At present, in the field of telecommunications, the development of value-added services is generally developed using a graphical development model or a scripted development model. Among them, in the graphical development mode, the business developer uses a plurality of service independent building blocks (SIBs) on the graphical development interface to connect with arrow lines to form a networked business process. The graphical development model is intuitive and easy to remember, making it suitable for beginners.

However, in a graphical development environment, because the service is connected by multiple SIBs through arrow lines, and the arrow line can point from any SIB to any other SIB, and the arrow line is equivalent to the goto statement in the scripting language. The business scripts are generated directly in the process of traversing the graphical process. The business scripts may be filled with goto statements. As a result, the business processes that are developed may be confusing and unclear, resulting in poor readability of the business scripts.

For example, Figure 1 shows a simple graphical process fragment. According to a simple depth-first traversal algorithm, the resulting script description is:

If(SIBl)

{

If(SIB2)

{

SIB3;

SIB6;

}else {

SIB4;

Goto SIB6;

}

}else

{

SIB5;

Goto SIB6;

}

As can be seen from the above description, the business script obtained by the depth-first traversal algorithm uses two goto statements. Thus, the structure is unclear and the readability is poor, that is, it cannot accurately reflect that SIB6 is the common end point of each process. Logical structure.

The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

The method for converting a graphical business process of the present invention into a business script, as shown in FIG. 2, includes the following steps:

Step 201: Determine a sibling SIB of each SIB according to the divergence and convergence of the graphical business process branch;

Here, in order to make the transformed business script have the characteristics of a structured language, it is necessary to analyze the trend of each branch of the SIB having more than one exit. If all the branches are finally aggregated to the same SIB, it is determined that the aggregated SIB is the The sibling SIB of the SIB with more than one exit, correspondingly, all SIBs from the SIB with more than one exit to its sibling SIB are within the scope of the SIB with more than one exit.

The respective branches may be a judgment SIB, a branch SIB, a basic call control SIB, etc.; for example, for the graphics service flow segment shown in FIG. 1, the SIB1 exit has two branches, namely, SIB2 and SIB5, and SIB2 has two. Branches: SIB3 and SIB4, all branches eventually converge to SIB6, SIB6 is the sibling SIB of SIB1, SIB6 is also the sibling SIB of SIB2, SIB3 And SIB4 is within the scope of SIB2, while SIB2, SIB3, SIB4 and SIB5 are within the scope of SIB1.

Determining the sibling SIB of each SIB according to the divergence and convergence of the graphical business process branch, specifically:

The sibling SIB of each SIB is determined according to the number of branches of the input SIB and the number of branch aggregations of subsequent SIBs on the service chain in which the SIB is located.

This step is implemented more specifically, as shown in FIG. 3, and includes the following steps:

Step 201a: After completing the graphical business process, set a corresponding sibling SIB number for each SIB in the graphical business process, and initialize the sibling SIB number corresponding to each SIB to zero; here, in actual application, generally The SIBs in the graphical service flow are numbered from 1 and there is no SIB with the SIB number being zero. Therefore, the SIB number of the sibling SIB corresponding to each SIB can be initialized to zero, indicating that the sibling SIB corresponding to each SIB is not determined. .

Step 201b: After receiving the input SIB number, it is determined whether the sibling SIB number corresponding to the input SIB is zero, and if yes, step 201c is performed; otherwise, step 201 is performed;

Here, the service developer selects any one of the ingress SIBs in the graphical business process as an input parameter, that is, as an input SIB; wherein the ingress SIB refers to an ingress SIB in each segment of the graphical business process, The graphics service flow segment shown in FIG. 1 is taken as an example, and the ingress SIB refers to SIB1.

The sibling SIB number corresponding to the input SIB is zero, indicating that the sibling SIB of the input SIB has not been determined, and the search is required; if the sibling SIB number corresponding to the input SIB is not zero, it indicates that the input SIB has been searched. The corresponding sibling SIB does not need to be searched.

Step 201c: Create a temporary variable indicating the number of branches for the input SIB, and set the value of the number of branches to the number of exit branches of the input SIB;

Here, the temporary variable refers to: a local variable created on the stack, corresponding to an auto type variable in a function of the C language, in this process determining the processing flow of the sibling SIB of the input SIB After the bundle, the temporary variables are all released, ie: all erased.

The specific processing flow for creating temporary variables is exactly the same as the existing processing for creating temporary variables, and will not be described here.

The number of exit branches of the input SIB can be obtained based on the number of arrow lines of the input SIB exit as described in the completed graphical business process.

Step 201d: determining whether the value of the number of branches is less than or equal to 1, if yes, executing step 201e, otherwise, performing step 201f;

Step 201e: If the value of the number of branches is equal to 1, set the sibling SIB number corresponding to the input SIB to the SIB number of the next SIB of the egress branch of the input SIB, and then perform step 201o, if the branch The value of the number is equal to zero, then the sibling SIB number corresponding to the input SIB is set to Μ, and then step 201ο is performed;

Here, if the number of branches is equal to 1, it indicates that the input SIB has only one egress branch, and its sibling SIB is the next SIB of the egress branch; if the number of branches is equal to zero, it indicates that the input SIB has no sibling SIB. Set the sibling SIB number corresponding to the input SIB to Μ; where Μ indicates that the input SIB has no sibling SIB. In actual application, the SIB number in the graphical service flow starts from 1, and sequentially numbers each SIB. Therefore, the value of Μ can be set to any value that does not overlap with the SIB number in the graphical business process, for example: You can set the value of Μ to -1.

Step 201f: Establish, for each SIB in the entire service, a temporary variable indicating the number of branch aggregations and whether the temporary variables are accessed, and set the value of the temporary variable to 0, and set the sibling SIB number corresponding to the input SIB to be N, and then Perform step 201g;

Here, each of the SIBs includes the input SIB and the next SIB of each branch outlet. The specific processing flow for creating temporary variables is exactly the same as the existing processing for creating temporary variables, and will not be described here.

N is used for subsequent detection of the ring process, that is: N indicates that the business process is ring-shaped, To terminate the traversal of the branch, therefore, in actual application, the value of N can be set to any value that does not overlap with the SIB number and M in the graphical business process. For example: You can set the value of N to -2.

Step 201g: The value of the variable that has been accessed by the input SIB is set to 1, and then it is determined whether the SIB number of the next SIB of the current exit branch is greater than zero, and if yes, step 201h is performed, otherwise, step 201m is performed;

Here, any one of the egress branches of the input SIB may be selected as the current egress branch, and the SIB number of the next SIB of the selected egress branch is used as an input parameter, and after the device receives the input parameter, the current egress branch is determined. Whether the SIB number of the next SIB is greater than zero;

If the SIB number of the next SIB of the current exit branch is less than zero, the current branch has been traversed, and no traversal is required. Step 201m is performed, and an expenditure branch is selected as the current exit branch for traversal.

In the following description, for the convenience of description, the next SIB of the current exit branch is referred to as the current SIB.

Step 201h: determining whether the current value of the variable of the current SIB is greater than zero, and if so, executing step 201m, otherwise, performing step 201i;

Here, if the value of the variable that the current SIB has accessed is greater than zero, it indicates that the SIB has been accessed on the current egress branch, and the service flow has a ring structure, and it is necessary to suspend the traversal of the branch and continue to traverse other egress branches, so , Step 201m needs to be performed.

Step 201i: Set whether the value of the variable of the current SIB is 1 and the value of the branch of the current SIB is increased by 1, and then determine whether the value of the branch aggregation of the current SIB is equal to the input SIB. The value of the number of branches, if yes, step 201j, otherwise, step 201k;

Here, after the variable value of the branch aggregation number of the current SIB is increased by 1, it indicates that there is one branch. Converged to the current SIB.

If the value of the branch convergence of the current SIB is equal to the value of the number of branches of the input SIB, it indicates that the current SIB is the sibling SIB of the input SIB.

Step 201j: Set the sibling SIB number corresponding to the input SIB to the SIB number of the current SIB, and release the temporary variable, and then perform step 201ο;

Here, the temporary variables include: the number of branches, whether they have been accessed, and the number of branch aggregations. Step 201k: Determine whether the sibling SIB number corresponding to the current SIB is equal to N, and if yes, perform step 201m, otherwise, perform step 2011;

Here, if the sibling SIB number corresponding to the current SIB is equal to N, it indicates that the service flow has a ring structure, and it is necessary to suspend the traversal of the branch and continue to traverse other exit branches. Therefore, step 201m needs to be performed.

Step 2011: The current SIB is used as a new input SIB, and then the algorithm is recursively invoked, and the SIB corresponding to the returned sibling SIB number is used as the new current SIB, and then step 201g is performed; where the recursive call algorithm refers to: Execution proceeds from step 201b to step 201o. It should be noted that: N is specifically used to: use the current SIB as a new input SIB, and re-execute step 201b, and then use it after detecting the ring process.

Step 201m: determining whether the input SIB has a next exit branch, if yes, then whether the value of each SIB in the entire service is cleared to zero, then step 201g is performed, otherwise, step 201n is performed;

Here, it can be judged whether or not the input SIB has a next exit branch according to the number of arrow lines of the exit of the input SIB in the completed graphical business process.

Step 201n: Set the sibling SIB number corresponding to the input SIB to Μ, and release the temporary variable, and then perform step 201ο;

Step 201: returning the sibling SIB number corresponding to the input SIB;

Here, returning the sibling SIB number corresponding to the input SIB means: returning to the business developer The sibling SIB number corresponding to the input SIB is returned, so that the service developer can further select the SIB number of the other ingress SIB as an input parameter, and determine the corresponding sibling SIB number for the other SIB.

It should be noted that, in step 2011, the algorithm is recursively invoked, and the obtained step 201ο returns the function of the sibling SIB number as: as a new current SIB, in order to continue processing the next chain on the subsequent chain of the input SIB. An SIB.

The returned SIB number corresponding to the input SIB has two cases: one returns the SIB number of the real sibling SIB of the input SIB, and the other returns M; specifically, if the input The SIB has a sibling SIB, and returns the SIB number of the sibling SIB of the input SIB. If the input SIB does not have a sibling SIB, the M is returned.

So far, the input SIB and the sibling SIB of all SIBs in the subsequent chain of the input SIB have determined that the start SIB of all the segments of the entire service can be used as the input SIB to call the steps from 201b to 201o, and the sibling SIB of each SIB can be determined.

In the subsequent process of determining the scope and generating the business script, the sibling SIB of each SIB can be known based on the sibling SIB number corresponding to each SIB.

Step 202: Determine the scope of each SIB according to the sibling SIB of each SIB. Specifically, determine the role of each SIB according to the sibling SIB of each SIB and the direction of the arrow line in the completed graphical business process. area.

Among them, when traversing the subsequent flow of each SIB, all SIBs before reaching its sibling SIB are within the scope of the SIB corresponding to the sibling SIB.

Step 203: Generate a service script according to the scope of each SIB and the sibling SIB of each SIB.

Specifically, the flow corresponding to the SIB in the scope of the SIB is written in the range of each branch flow of the SIB corresponding to the scope; and the flow after the sibling SIB and the sibling SIB is written in the subsequent flow of the corresponding SIB.

For the graphical business process fragment shown in Figure 1, the following business script description can be generated. Form:

If(SIBl)

{

If(SIB2)

{

SIB3;

}else

{

SIB4;

}

}else

{

SIB5;

}

SIB6;

As can be seen from the above description, the script generated by the method of the present invention discards the goto statement, and can clearly reflect the judgment branch structure of the business process, and the readability is greatly improved.

In order to achieve the above method, the present invention further provides a device for converting a graphical business process into a business script. As shown in FIG. 4, the device includes: a first determining unit 41, a second determining unit 42, and a generating unit 43; among them,
