detailed description

In view of the binding of existing IoT terminals with dedicated SIM cards and MSISDN numbers, communication and billing are realized through IMSI numbers and MSISDN numbers, resulting in occupation of communication number resources, resulting in low utilization of communication number resources and low revenue per card problem, the embodiment of the present invention assigns the terminal ID to the Internet of Things terminal when ordering services on the network side, and uses the terminal ID as the basis for charging, so as to solve the wasteful communication caused by the Internet of Things terminal relying on the operator's number for charging. For the problem of number resources, when the life of the IoT terminal is over, it can automatically initiate service unsubscription, avoiding unnecessary business monitoring of the IoT terminal whose life has expired, and saving network resources.

The technical solutions in the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the present invention. Apparently, the described embodiments are part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

Referring to FIG. 1 , it is a schematic diagram of the network architecture of the Internet of Things billing system provided by the embodiment of the present invention. As shown in the figure, the network architecture includes an Internet of Things terminal 11, an Internet of Things billing system 12, and a service server 13. The fee system 12 communicates with the IoT terminal 11 and the service server 13 respectively.

The IoT charging system 12 may include: a management server 121 , a charging server 122 and a service gateway 123 . The management server 121 is used to record the relevant information of the IoT terminal 11, and manage the IoT terminal 11 within its life cycle. Until the hardware of the IoT terminal 11 is scrapped. The billing server 122 is used to charge the IoT service used by the IoT terminal 11 according to the IoT terminal identifier (M_Product_ID) within its lifetime; the service gateway 123 is used for related services used by the IoT terminal 11, Generate business bills.

The service server 13 is used to provide relevant application services for the terminal 11 of the Internet of Things.

Based on the above system architecture, the main business process provided by the embodiment of the present invention includes service subscription flow, service billing process, and service unsubscription process.

In the service ordering process, the IoT terminal 11 reports its terminal device identification (assigned by the IoT terminal equipment manufacturer) to the management server 121, and the management server 121 assigns the IoT terminal identification (M_Product_ID) to the IoT terminal 11, and the billing server 122 allocates a code number resource for the Internet of Things terminal 11, and uses the code number resource to initiate an order service request to the service server 13 through the service gateway 123. After the order is successful, record the information between the Internet of Things terminal 11 and the order service on the management server 121 corresponding relationship.

When the Internet of Things terminal uses the ordered service for the first time, the management server 121 sets the state of the terminal to enable, and reports the M_Product_ID of the Internet of Things terminal to the service gateway 123 to generate the first service bill; the billing server 122 collects the first After creating a service bill, record the status of the service currently used by the IoT terminal as an activity, add tariff information to the bill, and complete billing and payment. When the Internet of Things terminal 11 subsequently uses the subscribed service, the service gateway 123 directly generates a service bill, and the billing server 122 completes charging and billing within the lifetime of the Internet of Things terminal.

In the service unsubscription process of the Internet of Things terminal, after the management server 121 receives the hardware scrapping request of the Internet of Things terminal, it initiates an unsubscribe service request to the billing server 122, and the Internet of Things billing server 122 sends a request to the Internet of Things through the Internet of Things service gateway 123. The service server 13 initiates an unsubscribe service request, and after receiving the result of processing the unsubscribe service, deletes the corresponding relationship between the IoT terminal requested to be discarded and the subscription service and the M_Product_ID assigned to these IoT terminals 11, and feeds back to the management The server 121 is used to update the relevant information of the IoT terminal 11.

In conjunction with FIG. 2, the flow of the Internet of Things terminal ordering service of the Internet of Things terminal billing management method is described in detail below. As shown in the figure, the flow includes the following steps:

Step 21: After receiving the service order request, the management server assigns a terminal identifier M_Product_ID to the IoT terminal that subscribes to the service, and correspondingly records the life cycle of the IoT terminal.

Specifically, the service order request may be submitted to the management server by a user using an Internet of Things terminal. Usually the IoT terminal hardware leaves the factory in batches, and the network terminal hardware users can submit the information of the batch of IoT terminal hardware in batches to realize the business ordering of the batch of IoT terminals. The IoT terminal hardware information may include: date of manufacture, user information using the IoT terminal, life cycle (the period is determined by the IoT hardware manufacturer) and other information.

The management server assigns a unique M_Product_ID to each received IoT terminal hardware, and the M_Product_ID is used as the basis for billing the IoT terminal.

Step 22, the management server sends a code number resource request to the charging server, and the request carries M_Product_ID.

The code number resource may include: an industry-specific SIM card number (IMSI number) and an operator number (MSISDN number) used by IoT terminals for communication. With the improvement of network services, virtual numbers or Internet numbers can also be used instead of operator numbers to realize communication between IoT terminals, IoT billing systems and service servers.

Step 23, the billing server records the M_Product_ID, allocates a code number resource for the IoT terminal, and sends it to the management server.

The code number resource is managed by the billing server, and the billing server assigns a unique communication number to the IoT terminal according to the M_Product_ID, and the communication number corresponds to the M_Product_ID one by one.

Step 24, the management server sends a service order request to the service server through the charging server, and the service server performs service order processing according to the request.

Specifically, after receiving the ordering service request initiated by the management server, the billing server records the IoT terminal information carried in the request (including information such as M_Product_ID, communication number, etc.), and sends the ordering service request to the service server through the service gateway, The order service request carries the identifier M_Service_ID of the service to be ordered.

Step 25, after the service is ordered successfully, the service server feeds back the order result to the billing server.

Step 26, the billing server records the corresponding relationship between the IoT terminal and the subscription service, and changes the status of the IoT terminal to an available status.

Preferably, when the billing server receives the subscription service result, it can modify the status of the IoT terminal to an available status. The available status does not mean that the IoT terminal has actually been put into use, but only means that the IoT terminal can be put into use. Only when its status is enabled, it indicates that the IoT terminal has started to be used, and its life cycle begins. Only when the user actually uses the subscribed service and generates a bill, the IoT terminal is enabled, and the billing system starts billing.

Step 27, the billing server sends the subscription service result to the management server, so that the management server records the correspondence between the IoT terminal and the subscription service.

After the Internet of Things terminal subscribes to the service, in the process of using the service, the Internet of Things billing system charges for the service used by the terminal within the lifetime of the Internet of Things terminal. The lifecycle of an IoT terminal starts when its status is set to enabled and ends when its status is set to terminated. When the Internet of Things terminal uses the subscription service for the first time, its status is set to enable; when the Internet of Things billing system receives a service unsubscribe request for the Internet of Things terminal, or when the Internet of Things billing system judges that the enabled state of the Internet of Things terminal continues When the time reaches the IoT lifetime, its status is set to Terminated.

The following describes in detail the process of ordering services for the first use of IoT terminals in conjunction with Figure 3. As shown in the figure, the process includes the following steps:

Step 31, when the Internet of Things terminal uses the subscribed service for the first time, the management server updates the state of the Internet of Things terminal to an enabled state.

The status of the IoT terminal is updated to the enabled state, which indicates that the life cycle of the IoT terminal starts, and the IoT billing system starts billing.

Step 32, the management server reports the M_Product_ID of the IoT terminal that uses the subscription service for the first time or the correspondence between the M_Product_ID and the subscription service (M_Service_ID) to the service gateway to generate the first service bill.

Step 33, the billing server collects the first service bill.

Step 34: After collecting the first service bill, the billing server records the status of the service subscribed by the IoT terminal as active according to the first business bill. This step is optional.

The billing server can record information about services ordered by IoT terminals, including the usage status of the subscription services. The status of subscription services is compatible with the status of IoT terminals. For example, when the status of subscription services is active, The status of the connected terminal is enabled.

Preferably, the generation time of the first bill can also be recorded on the billing server, and the generation time of the first bill can reflect the time when the Internet of Things terminal uses the subscription service for the first time.

After the Internet of Things terminal uses the service for the first time, the billing server can collect the service bill from the service gateway according to the set time or cycle, and the subsequent process of using the service by the Internet of Things terminal can be shown in Figure 4. The process includes the following steps:

Step 41, after the billing server collects the service bill from the service gateway, the billing server adds corresponding tariff information to the service bill.

Specifically, the billing server implements price approval processing by adding the tariff information of the subscribed service to the service bill. Preferably, before performing the price approval process, the business bill can be pre-processed, such as performing error correction and format check on the business bill.

Step 42, the billing server checks the status information of the IoT terminal with the management server according to the M_Product_ID of the IoT terminal corresponding to the service bill.

Step 43, the billing server receives the status information of the IoT terminal fed back by the management server.

Step 44, when the state of the Internet of Things terminal is enabled, the billing server performs billing according to the business bill and issues the bill.

Specifically, when the Internet of Things terminal status is enabled, it means that the Internet of Things terminal is still in the life cycle, and the billing server can perform billing, settlement, generation of daily statistical reports, and billing for the collected service bills. If the status of the IoT terminal is not enabled, such as the available status (this status indicates that the IoT terminal has subscribed to the service but has not yet used the service), or the terminated status (this status indicates that the IoT terminal has unsubscribed from the service, or the IoT terminal If the duration of the enabled state of the IoT terminal reaches the lifetime of the IoT terminal), the service usage of the IoT terminal will not be charged.

It can be seen from the above description that the embodiment of the present invention uses the M_Product_ID of the IoT terminal as the basis for billing, and the billing process is associated with the usage status of the IoT terminal. When the life of the IoT terminal expires, the billing is also corresponding Finish.

After receiving the service unsubscription request for the Internet of Things terminal, the Internet of Things billing system may perform service unsubscription processing on the corresponding Internet of Things terminal. The unsubscribe request can be initiated by an IoT terminal user. The Internet of Things billing system can also trigger a service unsubscription process for the Internet of Things terminal when it detects that the life cycle of the Internet of Things terminal expires.

The following describes in detail the unsubscribe process for the IoT terminal triggered by the IoT billing system when it detects that the life of the IoT terminal expires in conjunction with Figure 5. As shown in the figure, the process includes the following steps:

Step 51, when the management server monitors that the life cycle of the IoT terminal expires, it changes the status information of the corresponding IoT terminal to terminated.

Step 52, the management server initiates a service unsubscription request to the charging server.

Specifically, when the management server monitors that the duration of the enabled state of the IoT terminal reaches the lifetime of the IoT terminal, it considers that the lifetime of the IoT terminal has expired.

Step 53, the billing server sends a service unsubscribe request to the service server, so that the service server deletes the service subscribed by the IoT terminal.

Specifically, the billing server sends the unsubscribe service request to the service gateway, and the unsubscribe service request carries the service identifier (M_Service_ID) subscribed by the Internet of Things terminal, and the service gateway sends the unsubscribe service request to the service server, and the service server according to The service unsubscribe request of the Internet of Things terminal is unsubscribed, and the processing result is fed back to the billing server through the service gateway.

Step 54, the service server feeds back the processing result to the billing server.

Step 55: After receiving the processing result fed back by the service server, the billing server deletes the correspondence between the M_Product_ID of the IoT terminal and the ordered service (M_Service_ID), and cancels the terminal ID of the IoT terminal.

Step 56, the charging server returns the unsubscribe processing result to the management server. Further, the subscription service status of the IoT terminal can also be changed to be terminated.

Step 57, the management server deletes the related information of the corresponding IoT terminal according to the unsubscribe processing result returned by the billing server, such as the M_Product_ID of the IoT terminal and the state information of the IoT terminal.

Based on the same idea, the embodiment of the present invention also provides a billing system for the Internet of Things.
