In the following description, suffixes such as "module", "component", or "unit" used to denote elements are used only for the convenience of explanation of the present disclosure, and have no specific meaning in themselves. Thus, "module", "component" or "unit" may be used mixedly.
To solve the above technical problem, please refer to fig. 1, where fig. 1 is a schematic flowchart of a roaming payment method based on a block chain according to an embodiment of the present disclosure, where the method includes step S101 and step S102.
In step S101, a first operator platform obtains network segment selection auxiliary information configured by a second operator platform for providing a network segment service for a user terminal under the first operator platform.
It is understood that a mobile communication network having a mutual roaming agreement between a first operator platform and a second operator platform, wherein the first operator platform is a home operator platform and the second operator platform is a roaming operator platform, and the NSSAI comprises a set of one or more S-NSSAIs.
Further, step S101 specifically includes: and the first operator platform acquires network fragment selection auxiliary information configured by a second operator platform for providing the network fragment service for the user terminal from a block chain.
Compared with the related art, the roaming-site operator network directly configures the NSSAI for the roaming user, and the home site does not verify the NSSAI configured by the roaming-site operator network, or the NSSAI configured by the roaming-site operator network makes a fake, so that the network service quality of the user cannot be guaranteed.
In step S102, the first operator platform determines whether the network segment selection auxiliary information complies with an intelligent contract pre-created in a block chain, where the intelligent contract includes a mapping relationship, which is pre-achieved between the first operator platform and the second operator platform, about the network segment selection auxiliary information, and if so, step S103 is executed.
In this embodiment, the home network effectively verifies the NSSAI configured by the roaming network for the user by using the block chain intelligent contract technology, and the home network only executes step S103 to pay for the roaming network by confirming that the NSSAI configured by the roaming network for the roaming user conforms to the mapping relationship in the intelligent contract, so as to at least guarantee the roaming service quality of the user.
In step S103, the first operator platform pays a roaming fee to the second operator platform.
In some embodiments, the intelligent contract further comprises payment rules, and the first operator platform pays for the second operator platform according to the payment rules in the intelligent contract when confirming that the NSSAI configured for the user by the second operator platform conforms to the rules.
Referring to fig. 2, fig. 2 is a schematic flow chart of another roaming payment method based on a block chain according to an embodiment of the present disclosure, which includes, on the basis of the previous embodiment, confirming that a user terminal roams to a roaming area network and actually uses a slicing service provided by the roaming area network, and then verifying a configuration NSSAI corresponding to the actually used slicing service to ensure that the configuration NSSAI actually used by the user meets a rule, thereby completing a roaming charge settlement, and specifically, before a first operator platform obtains network slice selection auxiliary information configured by a second operator platform for providing a network slice service for the user terminal under the first operator platform (step S101), step S201 is further included.
In step S201, the first operator platform determines whether the user terminal roams to an operator network of the second operator platform and uses the network fragment service provided by the second operator platform, and if so, performs step S101 in which the first operator platform obtains network fragment selection auxiliary information configured by the second operator platform for providing the network fragment service for the user terminal under the first operator platform.
The NSSF (Network Slice Selection Function) of the roaming Network indicated in TS 23.501R 16 does not need to inform the home Network of the S-NSSAI value actually used, which means that the home Network operator does not know it from the roaming Network operator if the roaming Network does not follow a pre-agreed agreement between the roaming Network operator and the home Network operator. In the prior art, the S-NSSAI value actually obtained and used by the user in the roaming area network is not verified for the second time, which may result in that the network service quality of the roaming user cannot be guaranteed.
Compared with the related art, the embodiment determines whether the obtained configured NSSAI meets the mapping relationship between the network fragment selection auxiliary information previously achieved by the home network operator and the current roaming-site network operator by confirming that the user terminal enters the roaming network and actually uses the slice service provided by the roaming site, that is, the user terminal enters the roaming-site network and actually obtains and uses the configured NSSAI of the roaming-site network. In the process, the secondary verification of the S-NSSAI value actually obtained by the user in the roaming area network is realized, and the configuration NSSAI actually used by the user is ensured to follow the mapping relation agreement previously achieved by the home area network and the roaming area network.
Referring to fig. 3, fig. 3 is a schematic flow chart of another roaming payment method based on a blockchain according to an embodiment of the present disclosure, based on the previous embodiment, in this embodiment, a first operator platform creates an intelligent contract in the blockchain, and adds a payment rule in the intelligent contract, so as to implement an efficient roaming payment transaction between a home network and a roaming network, specifically, before the first operator platform determines whether the network segment selection auxiliary information conforms to an intelligent contract created in advance in the blockchain (i.e., step S102), step S301 is further included, step S102 is further divided into step S102a, and step S103 is further divided into step S103 a.

f(UE 1 ，X S-NSSAI2 ) Is about UE 1 Traffic volume X using service provided by N2 S-NSSAI2 The settlement function of (2). f (UE) 1 ，X S-NSSAI2 ) The function value of (1) is the settlement fee value which needs to be paid to N2 by N1. N1 and N2 may agree on the calculation expression of f () in advance, or may negotiate the calculation expression of f () between 3) and 4). For example, the specific negotiation procedure may be: 3.1) N2 modified T to T1{ [ g (UE1, X) S-NSSAI2 )→N2]|[C{S-NSSAI1，S-NSSAI2}in-chain]Sign T1, send T1 to N1, then in 4), N1 appends a signature to T1, broadcasting T1 to the blockchain.
X S-NSSAI2 Indicating that traffic X uses a network slice instance determined from the single network slice selection assistance information S-NSSAI2 (i.e., configuration NSSAI); → N2 denotes the number f (UE) 1 ，X S-NSSAI2 ) Funding the value of N2; c { S-NSSAI1, S-NSSAI2} is S-NSSAI mapping relationship verification information. Wherein S-NSSAI1 is UE 1 S-NSSAI subscribed in the home network, S-NSSAI2 is N2 is UE1 (according to UE) 1 NSSAI subscribed in its home network N1) configured S-NSSAI. Wherein NSSAI is a set of one or more S-NSSAIs; [ C { S-NSSAI1, S-NSSAI2} in-chain]Representing that the authentication information C { S-NSSAI1, S-NSSAI2} is in the blockchain and has both N2 and UE 1 The signature of (2).
In the process, the first operator platform sets that the user terminal under the first operator platform actually uses the configuration NSSAI of the second operator platform, the configuration NSSAI accords with the NSSAI mapping relation, and the first operator platform carries out payment settlement transaction on the second operator platform.
4)N 2 And (5) adding a signature to the T, and broadcasting the T to the block chain.
5)UE 1 When a certain service data stream needs to be mapped to S-NSSAI value of S-NSSAI 2 On the PDU session (or a network fragmentation selection information of s-nssai needs to be created) 2 PDU session of (C), C is set 0 {s-nssai 1 ，s-nssai 2 Is to C 0 Signature, will C 0 Is sent to N 2 。
Before 5), ascribing to N 1 Terminal equipment UE 1 Roaming into N 2 The coverage area can obtain the roaming area network N from N2 2 NSSAI, which is a standard procedure. 5) When the UE device applies an S-NSSAI, it either creates a PDU session based on the S-NSSAI, or maps the application data stream to an existing PDU session with S-NSSAI, which is a standard procedure
6)N 2 To C 0 Adding a signature to C 0 Broadcast to the blockchain.
If N is present 2 Not signing, or broadcasting C to the blockchain, then N 2 Will not be able to follow N 1 A settlement fee is obtained. Similarly, if the mapping relation in C is incorrect, i.e. UE 1 An incorrect correspondence, N, has been released intentionally or unintentionally 2 May not be directed to the UE 1 Providing service, i.e. disconnecting UE 1 To the service data connection.
Wherein, C in 6) 0 Is an example of C. Thus (with UE) 1 And N 2 Signed) C 0 Being broadcast to the blockchain will validate T. After this N 2 And N 1 Determining a UE according to an existing method 1 Traffic usage X of S-NSSAI2 And the fee is settled according to f () in T.
As optimized, f () UE 1 Can use UE N1 And (4) replacing. I.e. as long as they belong to N 1 All terminals of (2) can use T as settlement transaction. Rather than just a particular terminal. In this case, only example C of C 0 The terminal signed is attributed to N 1 And T is the effective transaction.
