Abstract

The invention discloses a fixed-mobile network integrated IP address resource management system, method and computer readable medium. A single demand conversion interface converts IP resource management requirement information of a fixed network or a mobile network into content of an IP assignment rule table and an IP resource pool, and generates record of assignment status of IP address based on IP assignment requirement information. Thereafter, an assigned IP lifecycle management module queries whether there is a corresponding IP assignment rule table or its IP assignment rule based on the IP assignment requirement information, when the IP assignment rule table or its IP assignment rule is found, checks whether there is an available IP resource pool based on the IP assignment requirement information, and when the available IP resource pool is found, obtains an available IP address from the IP resource pool. Conversely, when the corresponding IP assignment rule table or its IP assignment rules is not found, the available IP resource pool is not found, or the available IP address is not obtained, an exception processing module performs exception process or rejection of the IP assignment requirement information.

At the same time, the main content of this fixed network integrated IP address resource management method is as follows, and the rest of the content is the same as that shown in FIG. 1 , and will not be repeated here.

As shown in steps P1 and P2 of FIG. 2, when the northbound interface connection module 10 or the single demand conversion interface 11 (such as the presentation layer state transfer API) receives at least one When information C is required for IP resource management, start or trigger the filing operation of IP address resources. That is, the IP resource management requirement information C of the external system B about at least one of the mobile network and the fixed network can be converted into the IP assignment rule table 12 and the IP Contents required by both the resource pool 51 to establish the IP assignment rule table 12 and the IP resource pool 51.

As shown in steps P1 and P3 of FIG. 2, when the northbound interface connection module 10 or the single demand conversion interface 11 (such as the presentation layer state transfer API) receives at least one When the IP assignment requirement information D of the other party is generated, the IP bit is generated according to the IP assignment requirement information D of at least one of the mobile network and the fixed network of the external system B through a single requirement conversion interface 11 (such as the presentation layer state transfer API) A record of the assignment status of the address.

Furthermore, as shown in step P3 of FIG. 2 , FIG. 3 and the assignment status table in Table 1 below, the assigned IP life cycle management module 30 is based on the IP designation of at least one of the mobile network and the fixed network of the external system B. The configuration requirement information D expands the required IP assignment procedure, so that the assigned IP life cycle management module 30 starts to execute the IP assignment operation according to the assignment state of the IP address. For example, the assignment state of the IP address is defined as the type and assignment state (code) of the assignment state described in the assignment state table in Table 1 below, wherein the initial state of the IP assignment operation is the assignment state {I }, and the assignment status {I} table Indicates to start or trigger an IP assignment operation (such as an IP address assignment operation).

Table 1: Assignment status table

As shown in step P4 of Figure 2, Figure 3 and Table 1, the assigned IP life cycle management module 30 inquires whether there is a corresponding IP assignment rule based on the IP assignment requirement information D of at least one of the mobile network and the fixed network Table 12 or its IP assignment rules. When the corresponding IP assignment rule table 12 or its IP assignment rule is inquired (obtained) according to the IP assignment requirement information D of at least one of the mobile network and the fixed network, the assigned IP life cycle management module 30 can The assignment state in the IP assignment rule table 12 is set to {R}, and the assignment state {R} indicates that the IP assignment rule table 12 or its IP assignment rules have been queried (obtained).

As shown in step P5 of FIG. 2 , FIG. 3 and Table 1, the assigned IP lifecycle management module 30 inquires whether there is an available IP resource pool 51 according to the IP assignment requirement information D of at least one of the mobile network and the fixed network. . When the available IP resource pool 51 is inquired (obtained) according to the IP assignment requirement D of at least one of the mobile network and the fixed network, the assigned IP lifecycle management module 30 can assign the IP resource in the IP assignment rule table 12 The assignment status is set to {A}, and the assignment status {A} indicates that it has been queried (take Obtain) available IP resource pool 51.

Next, the assigned IP life cycle management module 30 can obtain an available IP address from the IP resource pool 51, and set the assignment status in the IP assignment rule table 12 to {F} to further return the IP address The IP address is assigned to the external system B, where the assignment status {F} indicates that the assignment of the IP address is successful. In addition, as shown in step P6 of FIG. 2 , the IP resource pool 51 can also be monitored by the IP resource pool management module 50 .

As shown in step P7 of FIG. 2, FIG. 3 and Table 1, when any IP assignment operation fails, for example, the assigned IP life cycle management module 30 assigns the IP according to at least one of the mobile network and the fixed network. Demand Information D No corresponding IP assignment rule table 12 or its IP assignment rules can be found, no available IP resource pool 51 can be found, no available IP address can be obtained from the IP resource pool 51, or IP cannot be successfully monitored In the resource pool 51, the exception processing module 60 can execute the exception processing operation to perform exception processing or return of the IP assignment requirement information D, and set the assignment status in the IP assignment rule table 12 to {RM}, wherein, The assignment status {RM} indicates the return of IP assignment request information D.

The IP assignment rule table setting module 40 can integrate the original existing or expanded fixed network IP assignment rule table and include the mobile network IP assignment rule through the IP assignment rule table 12, and the integrated IP assignment rule table 12 It may include at least one of the brand, IP category, specified network type, IP address resources divided according to supply area or equipment, required subnet length (Subnet Length), and service IP address, etc., and The IP assignment rule table 12 can be combined with the original existing equipment (such as physical equipment or virtual equipment) management, the supply and installation area management 82 of the IP assignment rule table management module 81 (see FIG. 4 ) and other common equipment resource databases.

At the same time, the assignment IP life cycle management module 30 can use the principle of the limited assignment state machine 80 to use the assignment state of the limited assignment state machine 80 to drive the acquisition of available IP addresses.

For example, the assignment IP life cycle management module 30 can set the initial state of the IP assignment operation as the assignment state {I} of the limited assignment state machine 80, so that after the assignment state {I}, the query The assignment state of the limited assignment state machine 80 when reaching the corresponding IP assignment rule table 12 is set to {R}. Next, the assignment IP life cycle management module 30 can drive to obtain the available IP resource pool 51 according to the assignment state {R} of the limited assignment state machine 80, so that after the assignment state {R}, the available IP resource pool will be obtained The assignment state of the limited assignment state machine 80 for the IP resource pool 51 is {A}. Next, the assignment IP life cycle management module 30 can drive to obtain an available IP address according to the assignment state {A} of the limited assignment state machine 80, so that after the assignment state {A}, the available IP address will be successfully obtained The assignment state of the limited assignment state machine 80 at address time is set to {F}. Then, the assigned IP lifecycle management module 30 can drive to establish available IP addresses and identification codes of required services in the fixed network IP resource common database 70 according to the assignment state {F} of the limited assignment state machine 80 .

If the IP assignment requirement information D is converted through the single requirement conversion interface 11 (such as the presentation layer state transfer application program interface), it is found that the input data of the IP assignment requirement information D is wrong (data If the data is abnormal), the assignment IP life cycle management module 30 can execute the assignment state {IM} of the limited assignment state machine 80, indicating that the input data of the IP assignment requirement information D is wrong and needs to be returned. If it is found that the corresponding IP assignment rule cannot be found during the IP assignment operation, the assignment IP life cycle management module 30 can execute the assignment state {RM} of the limited assignment state machine 80, indicating that the IP assignment rule cannot be obtained Return required. If it is found that there is no available IP resource pool 51 or no available IP address during the IP assignment operation, the assignment IP life cycle management module 30 can execute the assignment state {AM} of the limited assignment state machine 80, indicating that it is available If the IP resource pool 51 or the available IP address is insufficient, the item must be returned.
