Detailed ways

The preferred embodiments of the present invention will be described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described here are only used to illustrate and explain the present invention, and are not intended to limit the present invention.

Fig. 2 is a schematic diagram of the overall structure of the CRBT service system according to the present invention. As shown in Figure 2, the CRBT system includes:

One or more service control points, connected with service switching points and intelligent peripherals through SIU; and

A database, connected to at least one business control point.

Wherein, at least one service control point and the database are located on different devices.

According to the allocation of SIU, at least one of the one or more service control points and the database exchange data in C/S mode.

Wherein, one or more service control points are configured with a connection from each service control point to a service management point; and each service control point is connected to the service management point through a data link.

The CRBT service implemented in the way of separating the SCP and the DB will be described in detail below. Among them, the separation of SCP and DB is to run the functions of SCF and SDF on different machines respectively, and exchange data between them through the database in C/S mode, as shown in Figure 2, in SCP1, SCP2, SCP3 Only the database client and intelligent network platform software need to be installed on the Internet, and there is no need to install double-click software, because each SCP is for load sharing, and each SCP is working at the same time, and there is no mutual backup relationship between them. On each SCP, if the installed client is sybase, you need to configure the interfaces file and add it to the service name of the DB. If you install oracle, you need to configure the tnsname.ora file and add it to the service name of the DB. In the configuration file of the intelligent network software on each SCP, configure the address to connect to the database, and also fill in the IP address of the DB. It is also necessary to configure the connection between the SCP and the SMP on each SCP. The SCP and the SMP are connected through a data link, and the SCP actively establishes a link with the SMP. Configure the connection between the SCP and the SIU on each SCP. The SCP and the SIU are connected through a data link, and the SCP actively establishes a link with the SIU. In the configuration of SMP, only the connection between SMP and its own database needs to be configured, and the connection between SMP and SCP does not need to be configured. On the DB, only the database needs to be installed, and the intelligent network platform software does not need to be installed, or after the intelligent network platform software is installed, the intelligent network platform software does not need to be started. The connection of other physical nodes is the same as the traditional CRBT without any change. When loading services through SMP, you only need to load business logic and database scripts on one SCP, and other SCPs will automatically synchronize.

Fig. 3 is a flowchart of a method for making a service call in the CRBT service system according to the present invention. As shown in Figure 3, the method includes the following steps:

Step S302, when the communication network judges that the called user has the CRBT attribute, the call is connected, and the service switching point sends the call information of the call to the SIU;

Step S304, the SIU selects a service control point from one or more service control points according to a predetermined distribution mechanism, and distributes the call information to the service control point;

Step S306, after receiving the call information, the service control point triggers the CRBT call service, analyzes the call information, and queries the database according to the analysis result;

Step S308, sending the ring tone information queried from the database to the service control point, and sending the ring tone information to the service switching point through the SIU; and

In step S310, the service switching point interacts with the intelligent peripheral to obtain a physical ring tone corresponding to the ring tone information, and access it to the calling channel.

Wherein, step S310 includes the following processing: the service switching point searches the ring tone on the smart peripheral device according to the ring tone information; and the smart peripheral device packs the ring tone into a physical ring tone and sends it to the service switching point.

The method further includes a step for the user to order the CRBT tone: after the interface management platform of the CRBT interface machine receives the subscription message from the user, it inquires from the service management point about the corresponding relationship between the user number segment and one or more service control points, and The corresponding relationship is returned to the interface management platform; the interface management platform selects a service control point from one or more service control points according to the corresponding relationship, and sends the order information to the service control point; and the service control point interacts with the database and sends The color ring tone is set for the user.

Wherein, the user initiates the operation of ordering the ring tone through the WEBSERVER, and sends the ordering message to the interface management platform through the WEBSERVER.

In addition, the method also includes: the interface management platform returns the operation result of the WEBSERVER to the WEBSERVER, and displays the operation result to the user on the WEBSERVER.

The analysis results include calling and called numbers, current time, and date. The distribution mechanism is: make the call information on one or more service control points evenly distributed. The ring tone information includes: color ring tone number, storage server information, and specific location information.

Fig. 4 is a structural diagram of the management part of the CRBT service system of the present invention, Fig. 5 is a flow chart of the calling part of the CRBT service system of the present invention, and Fig. 6 is a flowchart of the triggering service initiated by the CRBT service system WEBSERVER of the present invention. The process of calling the CRBT service after the separation of the SCP and the DB and the process of triggering the CRBT service by the IMP of the CRBT interface machine will be described in detail below in conjunction with FIG. 4 to FIG. 6 .

First, describe the call process of the CRBT service with reference to FIG. 5 , as shown in FIG. 5 , the call flow chart of the CRBT service system of the present invention mainly includes the following steps:

Steps S502 and S504, in the call access part, the calling user sends the call to the communication network through the communication terminal, and the communication network judges that the called user has the color ring attribute, and the call is connected therefrom;

Step S506, the SSP sends the call information to the SIU;

Step S508, through the SIU, the information related to the call is transferred to the SCP, and the SIU distribution mechanism can evenly distribute the sent call information to SCP1 or SCP2 or SCP3 for processing;

Step S510, after the SCP receives the call-related information forwarded by the SIU, triggers the call service of the CRBT, analyzes the calling and called numbers, current time, date and other information according to the CRBT service logic, and analyzes the calling and called numbers according to the CRBT service logic , the current time, date and other information are queried in the DB;

Step S512, the ring tone information (color ring tone number, storage server information, specific location information, etc.) inquired from the database is sent to SCP;

Step S514, forward the inquired ring tone information (color ring tone number, storage server information, specific location information, etc.) to SIU;

Step S516, forward the ring tone information (color ring tone number, storage server information, specific location information, etc.) found to SSP;

Step S518, SSP searches relevant ring tone information on IP according to the ring tone information (color ring tone numbering, storage server information, specific location information etc.) that returns;

Step S520, after the IP queries the color ring tone, the physical ring tone is packaged and sent to the SSP; and

In steps S522 and S524, the SSP connects the physical ring tone to the calling channel, and the calling user can hear the ring tone.

Next, with reference to FIG. 6 , the flow of the IMP triggering the CRBT service by the CRBT interface machine will be described. The IMP of the CRBT interface machine triggers the CRBT service, which may be initiated by the WEBSERVER of the CRBT or by the camping system. As shown in FIG. 4 , it shows a schematic diagram of the structure of the IMP-triggered CRBT service in a CRBT service system in which SCP and DB are separated.

The following takes the ordered CRBT service initiated from WEBSERVER as an example to illustrate the implementation of the CRBT service system where the SCP and DB are separated, as shown in Figure 6, including the following steps:

Step S602, after the user logs into the ring tone system on the WEBSERVER, initiates the operation of ordering ring tones through the WEBSERVER;

Step S604, the WEBSERVER sends the order message to the IMP of the CRBT interface machine;

Step S606, the IMP queries the corresponding relationship between the user number segment and the SCP from the SMP;

Step S608, the SMP returns the corresponding relationship between the queried user number segment and the SCP to the IMP;

Step S610, according to the inquired corresponding relationship, the IMP sends an order message to the SCP to trigger the CRBT order service, and the order message triggering the CRBT service will be evenly distributed to each SCP;

Step S612, the SCP searches the database for ring tone information and user information according to the CRBT business logic, and sets the CRBT tone for the user;

Step S614, return the return result to the SCP after the DB operation is successful;

Step S616, the SCP returns the return result of the DB to the IMP; and

In step S618, the IMP returns the operation result of the database to the WEBSERVER, and displays the operation result to the user on the WEBSERVER.

During the CRBT call and order process, if one of the SCPs fails, the SIU in step S504 and the IMP in step S608 will evenly distribute the call or order message to the remaining two SCPs. If two SCPs fail, the SIU in step S504 and the IMP in step S608 will all distribute calls or order messages to the remaining SCP to trigger the ring back tone service. Only when all the SCPs fail, will the normal use of the CRBT service be affected. Thereby reducing the probability that services cannot be realized due to equipment problems. If the service is deactivated or uninstalled on one of the SCPs, the CRBT service cannot be used because all SCPs share one DB. To modify business data, you only need to modify it on one of the SCPs, and it will be automatically synchronized to each SCP.

There is a 1-to-N relationship between the DB and the SCP of the present invention, and the SCP can evenly process the received request for executing business logic, which greatly enhances the ability of the color ring service system to process business. Since the business processing is shared by each SCP load, the It reduces the processing pressure of a single SCP, thus effectively improving the success rate of business execution. The 1-to-N relationship between DB and SCP also greatly reduces the cost of equipment. On the basis of single DB and SCP, only need to add SCP equipment to effectively improve the ability of the CRBT service system to handle services and provide users with better services and functions, and expand the capacity of the CRBT system.

The above are only preferred embodiments of the present invention, and are not intended to limit the present invention. For those skilled in the art, the present invention may have various modifications and changes. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention shall be included within the protection scope of the present invention.
