Detailed Description
For a better understanding of the technical aspects of the present disclosure, reference is made to the following detailed description taken in conjunction with the accompanying drawings.
The method aims to solve the problems that a non-real-time mode of regular settlement is generally adopted for roaming settlement between a visited place operator and a home place operator, the settlement period is long, and the real-time query requirement of a user cannot be met. The disclosure provides a block chain-based roaming settlement method and a roaming settlement node. The following detailed description is made with reference to the accompanying drawings which respectively illustrate embodiments provided by the present disclosure.
In the initial stage, a blockchain is pre-constructed. The block chain comprises each visited roaming settlement node and each home roaming settlement node. The terminal of the user opens the roaming service and signs the service agreement of the roaming service. The visited access node and the home access node both approve the roaming service agreement and the financial settlement policy agreement, which is used for performing roaming settlement between the visited operator and the home operator. And the home roaming settlement node in the block chain generates a new block from the roaming agreement information containing the roaming service agreement and the settlement strategy information containing the financial settlement strategy agreement, and stores the new block in a block chain account book. The visited operator and the home operator can share the credible mutual-recognition roaming business service agreement and the financial settlement strategy agreement.
Fig. 1 shows a flowchart of a block chain based roaming settlement method provided by an embodiment of the present disclosure. The roaming settlement node comprises a visited place roaming settlement node, and the block chain-based roaming settlement method can be applied to the visited place roaming settlement node. As shown in fig. 1, the block chain based roaming settlement method provided in this embodiment includes the following steps.
Step 101, receiving a roaming bill and a detailed bill of a terminal sent by a visited place charging and accounting system.
When a user activates roaming service at a visited place, a visited place charging accounting system charges the service behavior of the user, generates a roaming bill and a detail bill of a terminal, sends the roaming bill and the detail bill to a visited place roaming settlement node, and the visited place roaming settlement node receives the roaming bill and the detail bill.
Step 102, roaming agreement information and settlement strategy information pre-stored in a block chain account book are obtained.
In the step, the visited roaming settlement node acquires roaming agreement information and settlement strategy information which are pre-stored in the block chain and are both approved by the visited roaming settlement node and the home roaming settlement node.
And 103, generating financial settlement information according to the roaming agreement information, the settlement strategy information and the roaming bill and the detailed bill.
In the prior art, when the terminal roams, the visited operator and the home operator settle accounts according to a set period, for example, the settlement is performed once every two months. And the user can calculate the roaming bill and the detailed bill of the terminal once only activating the roaming service once (for example, making a roaming call, surfing the internet for several days at the visiting place). Generally, one call is made to calculate a roaming bill and a detailed bill, a short message and an internet are calculated according to a preset period, and the period is set by a local operator. For example, when a user makes a roaming call, the visited charging accounting system calculates a roaming bill and detailed bill, but the bill sent to the terminal is sent according to a monthly bill.
The settlement period between the visited operator and the home operator is shortened, and as long as the user activates the roaming service once, the visited charging accounting system calculates the roaming bill and the detailed bill of the terminal once, and then calculates the financial settlement information between the visited operator and the home operator. That is, the visited roaming settlement node generates the financial settlement information according to the roaming agreement information, the settlement policy information and the roaming bill and detail bill.
Step 104, a first broadcast message is broadcast in the blockchain.
Wherein the first broadcast message comprises roaming bill and detail, financial settlement information and signature of the visited roaming settlement node. The first broadcast message carries the signature of the roaming settlement node of the local visit place, which indicates that the roaming settlement node of the local visit place approves the calculated financial settlement information.
In the embodiment of the disclosure, by using a block chain distributed data storage and intelligent contract technology, all roaming records of a terminal are linked, and the roaming settlement between a visited place operator and a home place operator does not adopt a non-real-time mode of periodic settlement any more, but adopts real-time settlement, so that the settlement period is short, the settlement work efficiency is improved, and the real-time query requirement of a user is met.
Fig. 2 shows another flowchart of a block chain based roaming settlement method provided by an embodiment of the present disclosure. Further, as shown in fig. 2, before the receiving the roaming bill and the detailed bill of the terminal sent by the visited charging and accounting system (step 101), the method further includes:
step 201, receiving a charging request sent by a visited charging and accounting system.
And the charging request is sent after the visited charging accounting system receives the charging request sent by the visited roaming settlement node and judges that the terminal is in a roaming state according to the charging request.
Step 202, obtaining the current user information of the terminal from the block chain account book.
In this step, the visited roaming settlement node obtains the current subscriber information of the latest terminal, i.e. obtains the latest subscriber subscription information, credit line, roaming charging policy, balance state and other information related to the subscriber. The user subscription information is matched with the roaming agreement information stored in the block chain account book, namely the user subscription is the roaming service agreement contained in the roaming agreement information.
It should be noted that, after the terminal opens the roaming service and signs the roaming service agreement, the home roaming settlement node stores the user information of the terminal in the block chain account book. The terminal can also update the user information, and a new block generated by adding the current timestamp to the updated user information of the terminal can be stored in the block chain account book through the home roaming settlement node. The current user information of the terminal stored in the blockchain account book is encrypted data.
Step 203, forwarding the current user information of the terminal to the visited place charging accounting system, so that the visited place charging accounting system charges the roaming service of the terminal according to the current user information of the terminal and the visited place network charging policy, and generates a roaming bill and a detailed bill of the terminal.
It should be noted that, when the visited place charging accounting system determines that the user balance is insufficient or the credit line is insufficient according to the current user information of the terminal, a service deactivation message may be initiated to the visited place access server, so that the visited place access server initiates a service deactivation instruction to the terminal through the visited base station side network element, thereby blocking the service behavior of the user.
Fig. 3 shows another flowchart of a block chain based roaming settlement method provided by an embodiment of the present disclosure. Further, the roaming settlement node comprises a home roaming settlement node, and the block chain-based roaming settlement method can be applied to the home roaming settlement node. As shown in fig. 3, the method further comprises:
step 301, receiving a first broadcast message broadcast by a visited roaming settlement node in a block chain.
Step 302, obtaining roaming bill and detailed list, financial settlement information and signature of visited roaming settlement node in the first broadcast message.
Step 303, acquiring roaming agreement information and settlement policy information pre-stored in the block chain account book.
And step 304, checking the financial settlement information according to the roaming agreement information, the settlement policy information, the roaming bill and the detailed statement, and broadcasting a second broadcast message in the block chain if the financial settlement information is correct.
In steps 301 to 304, after receiving the first broadcast message broadcast by the visited roaming settlement node, the home roaming settlement node obtains roaming agreement information and settlement policy information mutually acknowledged by the visited operator and the home operator from the block chain account book, and verifies the financial settlement information in combination with the roaming bill and the detailed bill information, and signs the first broadcast message when the verification is passed, and broadcasts the second broadcast message in the block chain. The second broadcast message comprises roaming bill and detail, financial settlement information, signature of visited roaming settlement node and signature of home roaming settlement node.
Fig. 4 shows another flowchart of a block chain based roaming settlement method provided by an embodiment of the present disclosure. Further, the block chain based roaming settlement method can be applied to a roaming settlement node. As shown in fig. 4, the method further comprises:
step 401, receiving a second broadcast message broadcast by the home roaming settlement node in the block chain.
Step 402, when the second broadcast message is verified to include the signature of the visited roaming settlement node and the signature of the home roaming settlement node, generating a new block according to the financial settlement information in the second broadcast message, and broadcasting the new block in a block chain.
In the prior art, the roaming service usage record of the terminal and the generation of the roaming bill and the detailed list are responsible for the visited charging and billing system, which causes the charging and billing processes to be opaque, thereby leading to dispute due to inconsistent data of both parties of the settlement.
In steps 401-402, a roaming settlement node in a block chain receives a second broadcast message broadcast by a home roaming settlement node in the block chain, when the second broadcast message is verified to include a signature of a visited roaming settlement node and a signature of the home roaming settlement node, the financial settlement information in the second broadcast message is determined to be approved by both a visited operator and a home operator, and the roaming settlement node encrypts the financial settlement information and then generates a new block to be broadcast to the block chain. The charging and charge-off process is relatively safe and transparent, thereby eliminating disputes between the visited operator and the home operator caused by inconsistent data of both parties of settlement.
Fig. 5 shows another flowchart of a block chain based roaming settlement method provided by an embodiment of the present disclosure. Further, the block chain-based roaming settlement method can be applied to a home roaming settlement node. As shown in fig. 5, the method further comprises:
step 501, obtaining the current user information of the terminal.
Step 502, generating a new block according to the current user information and the current timestamp of the terminal, and broadcasting the new block in the block chain.
In steps 501-502, the current user information of the terminal is the updated user information of the terminal. If the user updates the user information, the home access node acquires the updated user information of the terminal, namely acquires the updated user subscription information, credit line, roaming charging strategy, balance state and other information related to the user. And the home access node generates a new block according to the updated user information of the terminal and the current timestamp, and broadcasts the new block in the block chain so as to store the content in the new block in the block chain account book. Here, the stored current user information of the terminal is encrypted information.
