Description
Technical Field
The present invention relates to the field of communications technologies, and in particular, to a communication method and a communication system.
Background
In the 5G Network, the terminal is allowed to access to a 5G Core Network (5G Core Network, abbreviated as 5GC) in a non-3GPP manner, that is, without passing through a radio access Network defined by 3 GPP. A functional entity N3IWF (Non-3GPP Inter-Working Function, Non-3GPP interworking functional entity) dedicated to this access method is defined for the 3GPP, and a user terminal first establishes a tunnel connection with the N3IWF through an arbitrary network, then encapsulates protocol data interacting with the 5GC in the tunnel, and sends the tunnel to the N3IWF, and the N3IWF decapsulates the tunnel and forwards the protocol data from the terminal to the 5GC, thereby completing the interaction between the terminal and the 5GC and enabling the terminal to access the 5 GC. Meanwhile, in a 5G network, the 5GC provides a Quality of Service (QoS) guarantee function for the end user, that is, after the user terminal accesses the 5GC, the user terminal may request the required QoS parameters from the 5 GC. But since the tunnel connection between the user terminal to the N3IWF is completed outside of 5GC, the QoS of this connection cannot be guaranteed. This results in that after the user terminal obtains the QoS parameters from the 5GC, the link for data transmission can get the QoS guarantee before the data packet leaves the 5GC, and the QoS guarantee provided by the 5GC cannot continue when the data is transmitted in the tunnel between the terminal and the N3 IWF. This obviously degrades the user's business experience.
In the related art, to guarantee continuation of QoS, an interface address of an access network used by a terminal to establish a tunnel connection with an N3IWF is previously stored in a 5GC, and the 5GC transmits QoS parameters to the access network through the stored interface address to guarantee communication quality of a tunnel between the terminal other than the 5GC and the N3 IWF. However, in the QoS ensuring method in the prior art, since the terminal may establish a connection with the N3IWF based on the task network, the 5GC cannot store in advance the interface addresses of all access networks that the terminal may use, and further cannot ensure that the terminal can successfully acquire the QoS parameters provided by the 5 GC; in addition, the terminal access N3IWF may experience a multi-segment network, and the multi-segment network may be across operators, for example, in a 5GC in which the terminal first passes through a connected network and then passes through a telecommunication network to access a telecommunication, the QoS guarantee method in the prior art cannot achieve QoS parameter transfer across operators. The prior art cannot ensure that data transmission of the terminal outside the 5GC obtains the same QoS guarantee as that of the 5GC, so that the user experience is low.

Detailed Description
In order to make those skilled in the art better understand the technical solution of the present invention, the following describes the communication method and the communication system provided by the present invention in detail with reference to the accompanying drawings.
The communication method provided by the present invention is implemented based on a communication system, as shown in fig. 1 (fig. 1 is a schematic structural diagram of a communication system provided by an embodiment of the present invention), the communication system is constructed based on a blockchain, the blockchain includes a plurality of network nodes, the plurality of network nodes includes at least one second network node 22 and one first network node 11, where each network node represents a network function entity of a different operator. Preferably, in this embodiment of the present invention, the first network node corresponds to a functional entity of a 5G network of an operator, for example, N3 IWF.
The communication method provided by the invention is used for ensuring that the data transmission of the terminal in the first network node and each second network node obtains the same service quality assurance when the terminal accesses the first network node through at least one second network node in a non-3GPP mode.
It should be noted that, in the embodiment of the present invention, when the terminal accesses the first network node through the plurality of second network nodes in a non-3GPP manner, the plurality of second network nodes are in a serial connection relationship, that is, the terminal accesses the first network node sequentially through each second network node, for example, the terminal is connected to a WIFI of a hotel, the WIFI of the hotel accesses a china telecom IP backbone network, and further the terminal accesses an N3IWF of a china unicom 5G network through the china telecom IP backbone network, at this time, both the functional entity corresponding to the "hotel WIFI" and the functional entity corresponding to the "china telecom IP backbone network" belong to the "second network nodes", and both belong to the serial connection relationship; however, in some embodiments, when the terminal is not satisfied with the bandwidth obtained from one transmission link formed by the second network nodes when accessing the 5G network, the terminal can also simultaneously access the 5G network based on a plurality of transmission links, wherein each transmission link comprises at least one second network node, the terminal accesses different N3 IWFs of the 5G network based on different transmission links, and the process of determining the service quality guarantee by the terminal based on each transmission link is independently performed without mutual interference.
Fig. 2 is a flowchart of a communication method according to an embodiment of the present invention.
Referring to fig. 2, the communication method provided by the present invention includes:
step S101, the first network node broadcasts a first transaction to the blockchain, where the first transaction includes: and target service quality parameters corresponding to the target data link.
In the process that the terminal accesses the first network node through at least one second network node, the terminal firstly establishes a communication tunnel with the N3IWF corresponding to the first network node through the second network node, and then the terminal sends the data packet to the N3IWF through the communication tunnel, and then the N3IWF sends the data packet to the first network node.
The target data link in the invention refers to a data link corresponding to a data transmission process between the terminal and the N3IWF corresponding to the first network node. The network corresponding to the second network node is a network carrying the target data link, that is, the data transmitted by the target data link is transmitted based on the network corresponding to the second network node.
In step S101, after determining that the terminal has accessed itself, the first network node initiates a transaction with each second network node in the block chain, so that each second network node determines the qos guarantee parameter of the target data link based on the transaction. Specifically, the first network node broadcasts a first transaction to the blockchain, the first transaction comprising: and the physical meaning of the target service quality parameter is that the first network node provides service quality guarantee for the transmission of the data packet related to the target data link in the network corresponding to the first network node by using the target service quality parameter.
In the embodiment of the present invention, the target qos parameter includes one or more of a bandwidth, a delay, a jitter, a packet loss rate, and a burst tolerance.
Step S102, each second network node responds to the first transaction to generate a second transaction, respectively, where the second transaction includes: target quality of service parameters corresponding to the target data link.
After receiving the first transaction, each second network node determines whether the second network node can provide service quality guarantee for the target data link by using the target service quality parameter contained in the first transaction or not based on respective network resources, and if so, generates a second transaction, wherein the second transaction comprises the target service quality parameter corresponding to the target data link; if not, the second network node may feed back information denying the transaction to the first network node.
Step S103, each second network node broadcasts the signed second transaction to the blockchain.
After the second transactions are respectively generated by each second network node, each second network node adds a self signature to the corresponding second transaction and broadcasts the self signature to the block chain. The second network node adds a signature to the second transaction to indicate that the second network node agrees to perform the transaction.
The embodiment of the present invention does not limit the way in which the second network node signs the second transaction, for example, the second network node may add a signature to the second transaction by using its own private key, or the second network node may further generate a key based on a preset algorithm (for example, generate a hash value by using a hash algorithm), and add a signature to the second transaction by using the generated key.
Step S104, each second network node transfers the data packet on the target data link with the target quality of service parameter based on the second transaction signed by the first network node.
After receiving the second transactions sent by the second network nodes, the first network node adds self signatures to the second transactions, and broadcasts the signed second transactions to the block chain. The first network node signing the second transaction indicates that the first network node agrees to the transaction.
Each second network node receives the second transaction signed by the first network node, and the second network node detects that the first network node signs to agree with the transaction, so that the fact that the transaction is completed can be determined, namely, the fact that the data packet on the target data link is transmitted by the target service quality parameters is determined.
According to the communication method provided by the embodiment of the invention, the negotiation and confirmation of the service quality parameters are carried out between the network nodes corresponding to each operator based on the block chain, so that when the terminal accesses the first network node based on at least one second network node, the same service quality guarantee for data transmission can be obtained outside the first network node as inside the first network node, and further, the communication experience of the user is improved.
Fig. 3 is a flowchart of another communication method according to an embodiment of the present invention.
Referring to fig. 3, the present embodiment includes steps S101 to S104 of the embodiment shown in fig. 2, and on this basis, the present embodiment further includes, between steps S103 and S104:
and step S105, the first network node performs signature verification on each second transaction signed by the second network node.
In order to prevent an illegal third party from impersonating the second network node to participate in the communication process, the first network node verifies the signature of the second network node, for example, the signature of the second network node is verified by using a pre-stored public key of the second network node, or a key is generated by using a pre-agreed encryption algorithm, and whether the signature of the second network node is real and valid is determined by comparing whether the newly generated key is the same as the key corresponding to the signature of the second network node.
In step S105, if the signature of the first network node to the second network node is verified, it indicates that the first network node determines that the second network node agrees to the transaction, and the second transaction is from the real second network node, at this time, step S106 is executed to further add the self signature to the second transaction, so as to advance the transaction; if the signature verification of the first network node on the second network node is not passed, the second network node is possibly a fake node, and the transaction process is ended.
Step S106, the first network node adds its own signature to the current second transaction, and broadcasts the second transaction to the blockchain.
The current second transaction refers to the second transaction added with the signature of the second network node, the first network node adds the self signature to the current second transaction to indicate that the first network node agrees to the current transaction, and the second transaction added with the self signature is broadcasted to the block chain.
In this embodiment, step S104 specifically includes:
in step S1041, each second network node verifies the signature of the first network node.
After the second network node receives the second transaction broadcast by the first network node with the signature of the first network node, the signature of the first network node is verified to determine the authenticity of the received identity of the first network node.
Specifically, if the signature of the second network node to the first network node passes the verification, it indicates that the identity of the first network node is real, and the first network node has confirmed the transaction, and at this time, the following step S1042 is correspondingly executed, that is, the second network node determines that the second network node itself transmits the data packet on the target data link according to the target quality of service parameter; if the signature verification of the first network node by the second network node is not passed, the first network node is possibly a fake node, and at this time, the process of the method is ended.
Step S1042, the data packet on the target data link is transferred with the target quality of service parameter.
The second network node may set a relevant parameter of the target data link based on a target qos parameter corresponding to the target data link included in the second transaction, so that the transmission performance of the data packet is guaranteed by using the target qos parameter when the data packet included in the target data link is subsequently transmitted.
In practical applications, in the process of determining the target qos parameters through unified negotiation between the first network node and each second network node, the final transaction is achieved in the form of payment resources, that is, the first network node pays a certain resource to each second network node, so that the second network node transmits the data packet in the target data link according to the target qos parameters set by the first network node.
In the above embodiment, after the first network node and each second network node negotiate to determine the target qos parameter, the resource payment is performed by default through a line or according to a predetermined protocol.
However, in some embodiments, the first network node and each second network node may also negotiate to determine the amount of payment resources in the determination of the target quality of service parameter.
In this embodiment, the first transaction broadcast by the first network node further includes: the amount of exchangeable resources of the first network node, the second transaction generated by the second network node further includes: a requested resource amount of the second network node; the exchangeable resource amount of the first network node refers to the resource amount which can be paid to each second network node by the first network node; the requested amount of resources of the second network node refers to the amount of resources the second network node desires to obtain from the first network node. Specifically, after receiving the first transaction broadcasted by the first network node, the second network node determines the resource amount expected to be obtained from the first network node, that is, the requested resource amount, according to the network resource condition of the second network node and the exchangeable resource amount of the first network node included in the first transaction, and writes the requested resource amount in the second transaction. In some embodiments, preferably, the exchangeable resource amount of the first network node may be set to 0, that is, it indicates that the first network node expects each second network node to provide quality of service guarantee for it in a gratuitous manner according to the target quality of service parameter, in which case, if the second node does not agree to provide quality of service guarantee for the first node in a gratuitous manner according to the target quality of service parameter, the first node may regenerate the first transaction, which includes the rearranged exchangeable resource amount, to perform transaction negotiation with each second network node again.
Specifically, referring to fig. 4 (fig. 4 is a flowchart of another communication method provided in an embodiment of the present invention), in this embodiment, before the first network node adds its own signature to the current second transaction and broadcasts the current second transaction into the blockchain (step S106), the method further includes:
step S1, the first network node calculates the sum of the requested resource amounts of the second network nodes included in all the second transactions to obtain the amount of the resource to be paid.
Step S2, the first network node determines whether the exchangeable resource amount is greater than or equal to the resource amount to be paid.
When the first network node judges that the amount of the exchangeable resources is greater than or equal to the amount of the resources to be paid, the exchangeable resources currently held by the first network node are enough to be paid to each second network node, at this time, the first network node can determine that the transaction is established, and correspondingly, the subsequent step S106 is executed; and when the first network node judges that the exchangeable resource amount is smaller than the resource amount to be paid, the exchangeable resource currently held by the first network node is not enough to be paid to each second network node, and the transaction cannot be established, and at this moment, the process of the method is ended.
Fig. 5 is a flowchart of another communication method according to an embodiment of the present invention.
Referring to fig. 5, in this embodiment, the communication method not only includes steps S101 to S104 of the embodiment shown in fig. 2, but also includes step S102 ', and only step S102' will be described below.
In this embodiment, the first transaction further includes: identification of the target data link. Specifically, before step S102, the method further includes:
step S102', all network nodes except the first network node in the block chain determine whether a data packet corresponding to the target data link is transmitted in the network corresponding to the network node according to the identification of the target data link.

In the embodiment of the present invention, the identifier of the target data link is represented by an IPsec tunnel identifier, preferably, the identifier of the target data link is represented by an IPsec tunnel identifier triple, where the IPsec tunnel identifier triple includes: a Security Parameter Index value (SPI for short), a Security protocol type, and a network address; wherein the security protocol types include: using only Authentication Header protocol (AH), only Encapsulating Security Payload protocol (ESP), or both AH and ESP protocols; the SPI is a field contained in AH and ESP, and the SPI corresponding to the data packet can be identified from the data packet transmitted on the network; the network address comprises one of a source address and a destination address of the tunnel, the network address is the source address when the target data link represents the data flow from the N3IWF to the terminal, and the network address is the destination address when the target data link represents the data flow from the terminal to the N3 IWF.
