Background
With the popularization of the internet and the development of network application technology, the functions of application systems become stronger and the scale of the application systems also becomes larger and larger. Typically, for a large application system, hundreds of service point servers are grouped into a clustered application system network. In order to speed up the response of specific application functions and provide concurrency performance, these data are generally stored in a central database shared by a plurality of service terminals. Each service end can read data from the central database by communicating with the central database in real time.
In the process of distributing data to each service terminal by the existing central database (as shown in fig. 1), the data source stores the data in the data source side database, the data source side database distributes the data to the service terminal side database, and the service terminal obtains data from the service terminal side database through the user location register to update and use the data for the service terminal. However, each service end in the existing data distribution system needs to deploy one set of equipment and two sets of equipment, which makes the cost for deploying the database and the maintenance cost high. Meanwhile, data synchronization between the service side database and the user location register is completed through tseh (triggered synchronization), and processing capacity of tseh is limited, and only 100 records can be updated per second, which greatly limits the speed of data distribution.
Thus, the prior art has yet to be improved and enhanced.

The invention will be further explained by the description of the embodiments with reference to the drawings.
Referring to fig. 2, fig. 2 is a flowchart illustrating an NP data distribution method according to a preferred embodiment of the present invention. The method comprises the following steps:
s100, caching NP data in a data source by a central point server, and writing the NP data into a first local storage space of the central point server;
s200, the NP data are sent to a service point server, so that the service point server caches the NP data in a cache of the service point server for a service end to call.
The embodiment provides an NP data distribution method, which includes storing NP data of a data source in a central point server, transmitting the NP data to a local storage space of a service point server through a network in a text data mode through the central point server, and reading the stored NP data into a cache through a second user position register by the service point server. Therefore, the deployment of a large number of databases can be avoided, and the installation cost and the maintenance cost of the databases are avoided. Meanwhile, NP data are transmitted in a text mode, and the NP data distribution efficiency is improved.
Specifically, in step S100, the NP data is number portability (number portability), which means that a phone user can change its access point or home carrier while keeping the number unchanged. The NP data may be represented as (B, B '), where B is the subscriber number and B' is the current routing number of the subscriber.
Illustratively, the caching, by the central point server, NP data in a data source and writing the NP data in the first local storage space thereof includes:
s101, a midpoint server reads NP data in a data source through a first position register configured by the midpoint server, and writes the NP data into a cache;
s102, writing the NP data in the cache into a first local storage space of the NP data in a text mode.
Specifically, the central point server stores the NP data in a text form, and the NP data is stored in a first local storage space of the central point server. In this embodiment, the NP data is stored in a first local file in a first local storage space. That is, the central point server pre-establishes a first local file, where the first local file is used to store NP data in the first user location register. In practical application, the first user location register may be independent from the central point server, that is, the central point server is connected to the data source, and the NP data in the data source is cached in the cache of the central point server through the first user location register, and then the NP data in the cache is synchronized to the preset first local file, so as to implement storing the data in the data source in the local storage space of the central point server.
Further, in the step S200, the service point server is arranged at the service side, and is configured to synchronize and store NP data in the central point server, and store the NP data in a cache for a terminal device (denoted as a service end) at the service side to call.
Illustratively, the sending the NP data to the service point server, so that the service point server caches the NP data in its cache for the service end to call specifically includes:
s201, a central point server and a service point server establish network connection, and NP data stored in a first local storage space of the central point server is transmitted to the service point server;
s202, the service point server receives and stores the NP data in a second local storage space of the service point server, and writes the NP data in the second local storage space into a cache through a second user position register configured by the service point server for the service terminal to call.
Specifically, a network connection, such as an ftp connection, may be established between the central point server and the service point server, and the central point server communicates and transmits data through the network connection. That is, the central point server synchronizes its stored NP data to the service point server through network transmission. In practical application, in order to increase the transmission speed of NP data, when the central point server synchronizes NP data to the service point server, the central point server compresses the first local file for storing NP data, and sends the compressed file to the service point server, so that the data transmission speed can be increased.
In this embodiment, the service point server proposes a second local file in a second local storage space in advance, where the second local file is used to store NP data transmitted by the central point server, that is, the service point server stores the NP data in the second local file in a file form. And the second user position register reads the second local file and caches NP data in the second local file in the second user position register. In practical application, the central server supports breakpoint continuous transmission, that is, when transmission is interrupted and then resumed due to network reasons or other factors, the breakpoint continuous transmission is started to continue transmission from the last transmission point.
In order to ensure that the service end can call NP data in real time, the second user position register comprises a second main user position register and a second standby user position register, and the second main user position register and the second standby user position register are both connected with the service point server. That is, the second user location register includes two user location registers, one for use and one for standby, which are respectively marked as a second main user location register and a second standby user location register; both user location registers use a second local storage space (e.g., D-disk, E-disk, etc.) for storing NP data transmitted by the central server, so that both the second primary user location register and the second backup user location register can read and cache NP data in the storage space. Therefore, the consistency of data between the main user position register and the standby user position register can be ensured, and meanwhile, the burden of network transmission of the central point server is increased. It is worth mentioning that the second primary user location register and the second backup user location register may be independent of the service point server.
Further, the status of the second primary user location register and the second backup user location register each comprise an available status and an unavailable status, wherein the second primary user location has a higher priority than the second backup user location register. That is, the status of the second master user location register is preferentially in an available state and the status of the second standby user location register is unavailable; and the status of the second spare user position register is changed to available when the status of the second master user position register is unavailable and to unavailable when the status of the second master user position register is changed to available. In practical applications, the state of the second master user location register may be detected at predetermined intervals, and the state of the second backup user location register may be adjusted according to the state of the second master user location register to ensure that only one of the second master user location register and the second backup user location register is in an available state.
Further, in order to avoid data damage or loss in the service point server, a backup file is arranged in the service point server, and the backup file is used for backing up the NP data transmitted by the central point server, so that when the second local file is lost or damaged, the NP data in the backup file can be copied to the second local file to recover the NP data, thereby avoiding resynchronization of the NP data in the central point server and reducing network overhead.
In an embodiment of the present invention, the receiving and storing, by the service point server, the NP data in the second local storage space thereof, and writing, by a second user location register configured therewith, the NP data in the second local storage space into a cache, so that the service terminal specifically includes:
s201a, the service point server receives and stores the NP data in a second local storage space of the service point server, and acquires a first storage space occupied by the NP data stored in the central point server;
s202a, comparing the first storage space with a second storage space occupied by the received NP data;
and S203a, when the first storage space is the same as the second storage space, writing NP data in the second local storage space into a cache through a second user location register configured by the first storage space and the second storage space, so as to be called by the service terminal.
Specifically, the first storage space refers to a space occupied by the NP data in the central point server, that is, a size of the first local file. The second storage space is a storage space occupied by the NP data received by the service point server, namely the size of the second local file. The comparison between the first storage space and the second storage space refers to judging whether the size of the first local file is consistent with that of the second local file, so that whether all NP data in the central point server are transmitted to the service point server can be determined. When the size of the first local file is the same as the size of the second local file, a preparation for an incremental update operation may begin; and when the size of the first local file is not equal to that of the second local file, the service point server deletes the data in the second local file and requests the central point server to retransmit the NP data.
In another embodiment of the present invention, after the sending the NP data to the service point server, so that the service point server caches the NP data in its cache for the service end to call, the method further includes:
s300, the second user position register acquires a first data volume of the NP data cached by the first user position register, and calculates a difference value between the first data volume and a second data volume of the NP data cached by the first data volume;
s400, comparing the difference value with a preset difference value threshold value, and when the difference value is larger than the preset difference value threshold value, requesting the NP data from the data source again.
Specifically, the difference threshold is preset, for example, 1000, 5000, and the like. The first data amount refers to the number of pieces of NP data in the first user position register, and the second data amount refers to the number of pieces of NP data in the second user position register. In practical application, when the difference is greater than a preset difference threshold, the NP data update request may be automatically sent to the central server again, and the number of update failures may be recorded. Therefore, the integrity of NP data updating can be ensured, and the information of updating failure can be fed back in time.
The present invention also provides an NP data distribution system, as shown in fig. 3, including: the central point server 100 is used for caching NP data in a data source, and writing the NP data into a first local storage space of the central point server 100; and sending the NP data to the service point server 200, so that the service point server 200 caches the NP data in its cache for the service end to call.
The NP data distribution system, wherein the service point server 200 is configured to receive and store the NP data in a second local storage space thereof, and write the NP data in the second local storage space into a cache through a second user location register configured therein, so as to be called by the service terminal.
The NP data distribution system, wherein the second user position register comprises a second main user position register and a second spare user position register, and the second main user position register and the second spare user position register both use the first local storage space.
In addition, the specific processes performed by the NP data distribution system are described in detail in the method, and are not described herein.
Finally, it should be noted that: the above examples are only intended to illustrate the technical solution of the present invention, but not to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, it will be understood by those of ordinary skill in the art that: the technical solutions described in the foregoing embodiments may still be modified, or some technical features may be equivalently replaced; and such modifications or substitutions do not depart from the spirit and scope of the corresponding technical solutions of the embodiments of the present invention.
