Description

Block chain-based distributed charging method, device and system
Technical Field
The present invention relates to the field of communication charging, and in particular, to a distributed charging method, apparatus, and system based on a block chain.
Background
In the field of telecommunications, the basic flow of online charging is as follows: when a user uses a Service (e.g., voice call or internet access), an MSC (Mobile Service Switching Center) initiates a Service use request to an SCP (Service Control Point), the SCP initiates a Charging request to an OCS (Online Charging System) device by sending a CCR message, the OCS device obtains a balance of the user, deducts a certain fee and gives the SCP a certain Service use limit (call duration or data traffic), and the SCP receives the limit and provides the Service for the user. When the quota is not enough, the SCP can continuously send the CCR message to the OCS equipment to apply for a new service quota, and the OCS deducts the used quota and sends the new quota to the SCP after receiving the CCR message. The SCP may continue to send the CCR to the OCS until the subscriber ends service usage or the subscriber balance is exhausted.
Early billing models were essentially one account per device, so each device was managed (top-up, billing, etc.) individually. Later, services like group numbers, family paternity numbers, etc. appeared, and single accounts began to support multiple devices. With the development of technologies such as the internet of things, the number of devices that a single account needs to support increases, and the devices may all be online at the same time. For example: an internet of things service provider can access over million sensor devices to charge through an operator network at the same time, but the provider may only need one account to count to pay, and how to charge and manage the single-account mass terminal is a problem to be solved urgently at present.

Detailed Description
The technical solutions in the embodiments of the present invention will be described below with reference to the drawings in the embodiments of the present invention.
Fig. 1a is a schematic structural diagram of a blockchain, where the blockchain is a distributed ledger, and a technical solution for collectively maintaining a reliable database in a decentralized and distrusted manner. The block chain comprises a plurality of blocks, wherein a plurality of transaction records are recorded in each block (Bblock), and the transaction records also comprise the hash value of the previous block, so that all the blocks are connected in sequence to form the block chain.
The smart contracts (chaincodes) are event driven, have status (executed or not) and run on top of each ledger in the blockchain network, enabling management of programs of data on the ledger. The intelligent contract is represented as a computing program, which is similar to the contract in real life, the computer code of the intelligent contract specifies the rules and logic of transaction, the intelligent contract is executed after meeting the transaction conditions after a user calls the intelligent contract, and the transaction result is written into the account book.
For example: if the user wants to buy the assets, a transaction calling a BuyOneasset intelligent contract function is sent, the intelligent contract reads the fund balance and the residual quantity of the assets of the user from the block chain, the fund balance and the asset quantity of the user are modified after the transaction condition is met, and when the transaction result is agreed and written into an account book, the user is indicated to finish the transaction of purchasing the assets successfully.
One of core technologies of the blockchain is a consensus mechanism, and the consensus mechanism in the blockchain aims to solve a Byzantine fault-tolerant consensus scene, that is, nodes in the blockchain network are not trusted with each other, and there may be malicious lying nodes. Each node in the blockchain network is likely to be a "lying" node, but when a plurality of nodes are gathered in a network, the consensus result is a credible result. The main role of the consensus algorithm is to let all nodes in the block chain record the same valid transaction block.
For example: a fast consensus mechanism, namely, PoE (proof of end) provided by the fabric project is described. The core mechanism of the consensus mechanism is that a plurality of endorsement nodes (endorser peers) run intelligent contracts and endorse running results (endorsements) (the endorser peers are guaranteed to be the results sent by a specific endorser peer by signing the contents of the running results of the endorser peers per se). The endorser peer is a certain peer established according to specific service requirements, and is not different from other peers. The user can set an endrser peer to be trusted by the intelligent contract and a verification policy (endrse policy) for a plurality of endrsements according to actual requirements. For example: the client (client) sends an intelligent contract running request (progress) to the 3 endorser peers, and endorse policy may require that the 3 endorsegents contents must be consistent, or that at least two endorsegents contents are consistent. The endpiece returned by the collector endrser peer is contained in the transaction block and is broadcast to all peer nodes (including endrser peers) in the blockchain network by the inclusion of an orderer (a node or cluster providing consensus services, also known as a consensus network) in one transaction block. The peer checks the received transaction block, and the transaction block satisfying endirsepolarity is considered as a valid transaction block, and the transaction block is written into the block chain.
In the block chain network, different peers can form different channels, when a transaction block is sent to an orderer for broadcasting, the orderer only broadcasts the transaction block to the peers in the channel corresponding to the transaction block, and peers not corresponding to the channel do not receive the transaction block. Thus, the effect of protecting data privacy can be achieved. An orderer is a service (ordering service) in itself, and different channels can use either the same orderer or different orderers to distribute the load.
The embodiment of the invention provides a structural schematic diagram of a distributed charging system based on a block chain, which is called as a charging system for short, and the charging system comprises: one or more charging subnetworks, one or more operator charging nodes, one or more service control nodes, one or more terminals, and a consensus network.
Each charging sub-network is a block chain network, different charging sub-networks have different charging sub-channels, and data in different charging sub-channels are isolated from each other. Each charging sub-network comprises a plurality of charging sub-nodes, and the charging sub-nodes can be network elements deployed by a telecommunication operator or network elements deployed by a third party. Each charging sub-node in the charging sub-network is a block chain node, each charging sub-node is stored with a charging sub-account book and an amount distribution account book, the charging sub-account book records the charging result of the charging sub-node, and the amount distribution account book records the amount distribution record of the main account. Optionally, each charging sub-node includes an OCS (online charging system), an AMA, and a peer (peer node), where the OCS is configured to calculate a charging result according to the charging request, the AMA is configured to update an amount of a sub-account according to the charging result, and the peer is responsible for recording a charging sub-account and allocating an account for the amount, and interacting with other block link nodes.
The quota distribution network is also a blockchain network and comprises a plurality of blockchain nodes. It should be noted that, because the credit allocation network includes the charging subnet, the charging child node in the charging subnet is not only the block link node in the charging subnet, but also the block link node in the credit allocation network. The quota distribution network corresponds to one charging main channel, different operators have different charging main channels, and data in different channels are isolated from each other. The operator charging node is stored with an amount distribution account book, and the amount distribution account book records the amounts of main accounts of all users and the amounts of sub-accounts of the main accounts on each charging sub-node. The service control node is used for acquiring the user information and the service information of the terminal and sending the user information and the service information of the terminal to the charging sub-node in the charging sub-network for charging.
The consensus network is used for achieving consensus on data in the block chain network, and all block chain link points in the block chain network record the same block. And a consensus network is arranged in each charging sub-network, and the consensus network in the charging sub-networks comprises a plurality of charging sub-nodes in the charging sub-networks. The quota distribution network is also provided with a consensus network, and the consensus network comprises a plurality of nodes (which can be charging sub-nodes, operator charging nodes, or both charging sub-nodes and operator charging nodes) in the quota distribution network.
Optionally, the charging system may further include an index server, where the index server is configured to store a mapping relationship between the user identifier and the primary account, and a mapping relationship between the primary account and a sub-account on each charging sub-node.
