Detailed Description

The following detailed description of embodiments of the invention refers to the accompanying drawings. It should be understood that the detailed description and specific examples, while indicating the present invention, are given by way of illustration and explanation only, not limitation.

At present, many internet applications support a two-way connection mode, that is, a client and a server simultaneously adopt different physical paths to establish a data connection relationship, so as to obtain a larger bandwidth and higher reliability.

Meanwhile, the user terminal may be connected to a plurality of different networks, for example, two different mobile communication networks at the same time. The user terminal can therefore be connected to the server simultaneously via two data connections of different physical paths, respectively. The commonly used connection technology is MPTCP (Multi-Path TCP Protocol) technology.

In order to solve the foregoing problems, an embodiment of the present invention provides a method for adjusting bandwidth resources, which is applied to a first network system. The first network system establishes communication connection with the user terminal, provides bandwidth resources with a first resource amount for the user terminal, and simultaneously establishes communication connection with the second network system, and the second network system provides bandwidth resources with a second resource amount for the user terminal. The first network system and the second network system may be mobile communication network systems belonging to different operators. The user terminal may establish a multipath connection with a correspondent node, where the total bandwidth resource is a sum of the first resource amount and the second resource amount, based on the bandwidth resource of the first resource amount provided by the first network system and the bandwidth resource of the second resource amount provided by the second network system, and the correspondent node may be another user terminal or a server.

Fig. 1 is a flowchart of a method for adjusting bandwidth resources according to an embodiment of the present invention, which is applied to a first network system. As shown in fig. 1, the bandwidth resource adjustment method includes the following steps:

step S101, in response to the predicted available resource amount of the bandwidth resource of the first network system being smaller than the first resource amount, determining a pre-adjusted resource amount for the user terminal based on the first resource amount.

The predicted available resource amount refers to a resource amount of bandwidth resources that the first network system is predicted to provide for the user terminal at a current location, where the user terminal is currently located.

In one embodiment, the pre-adjusted resource amount is a difference between the first resource amount and the pre-provisioned resource amount.

In one embodiment, before the first network system determining the pre-adjusted amount of resources for the user terminal based on the first amount of resources in response to the predicted amount of available resources of the bandwidth resources of the first network system being less than the first amount of resources, the method further comprises: and receiving first multi-path connection reminding information sent by the user terminal.

The first multi-path connection reminding information comprises a network identifier of the second network system, the first multi-path connection reminding information is used for indicating that the user terminal establishes a multi-path connection currently, and the other sub-connection in the multi-path connection is borne by the second network system.

In one embodiment, after receiving the first multi-path connection reminding information, the first network system extracts the terminal identifier of the user terminal and the network identifier of the second network system from the first multi-path connection reminding information, and stores the terminal identifier of the user terminal and the network identifier of the second network system in an associated manner.

And S102, generating a bandwidth resource adjustment transaction based on the pre-adjustment resource amount and the preset intelligent contract.

The preset intelligent contract is an intelligent contract preset in the block chain network. The blockchain network includes a first blockchain network and a second blockchain network.

The first blockchain network is a blockchain network in which the first network system, the second network system and the user terminal are located, that is, the first blockchain network is a public blockchain network.

The second blockchain network is a blockchain network where the first network system and the second network system are located, and a node of the second blockchain network does not include a user terminal, that is, the second blockchain network is a private blockchain network. The second blockchain network is, for example, a private blockchain network between the respective operator network systems.

In one embodiment, the bandwidth resource adjustment transaction includes the amount of the pre-adjusted resource and a network identification of the second network system. The data format of the bandwidth resource adjustment transaction is as follows: t1{ [ N2], [ r → UE ] }. Wherein, T1 refers to a bandwidth resource adjustment transaction; n2 refers to the second network system, r refers to the amount of pre-adjusted resources, and UE refers to the user terminal. N2 may be represented by a network identifier of the second network system, and the UE may be represented by a terminal identifier of the user terminal. [ N2] is an input of a bandwidth resource adjustment transaction T1, indicating that the bandwidth resource corresponding to the pre-adjusted resource amount r is provided by the own bandwidth resource of the second network system N2. [ r → UE ] is an output of the bandwidth resource adjustment transaction T1, indicating that the second network system N2 allocates the bandwidth resource corresponding to the pre-adjusted resource amount r to the user terminal UE.

In one embodiment, the first network system signs the bandwidth resource adjustment transaction according to a preset intelligent contract after generating the bandwidth resource adjustment transaction and before sending the bandwidth resource adjustment transaction to the second network system.

Step S103, sending the bandwidth resource adjustment transaction to a second network system, so that the second network system adjusts the resource amount of the bandwidth resource provided for the user terminal from the second resource amount to a third resource amount based on the bandwidth resource adjustment transaction and the preset intelligent contract.

Wherein the third resource amount is the sum of the second resource amount and the pre-adjusted resource amount.

In an implementation scenario, in the case that the second network system is a fifth generation mobile communication network system, the second network system may adjust the resource amount of the bandwidth resource provided for the user terminal from the second resource amount to a third resource amount by a standard procedure defined in TS 23.502.

In one embodiment, the step of sending the bandwidth resource adjustment transaction to the second network system includes: and sending the bandwidth resource adjustment transaction to the second network system based on the prestored network identification of the second network system.

In an embodiment, after sending the bandwidth resource adjustment transaction to the second network system, the method further includes: the first network system adjusts the resource quantity of the bandwidth resource provided for the user terminal from the first resource quantity to a fourth resource quantity. Wherein the fourth resource amount is a difference between the first resource amount and the pre-adjusted resource amount.

In an implementation scenario, in the case that the first network system is a fifth generation mobile communication network system, the process of the first network system adjusting the resource amount of the bandwidth resource provided for the user terminal from the first resource amount to the fourth resource amount may be completed by a standard process defined in TS 23.502.

The bandwidth resource adjusting method provided by the embodiment of the invention comprises the steps of firstly, responding to the situation that the predicted available resource amount of the bandwidth resource of a first network system is smaller than a first resource amount, and determining the preset resource amount aiming at a user terminal based on the first resource amount; then, based on the preset resource amount and the preset intelligent contract, generating a bandwidth resource adjustment transaction; and finally, sending a bandwidth resource adjustment transaction to a second network system, so that the second network system adjusts the resource quantity of the bandwidth resource provided for the user terminal from the second resource quantity to a third resource quantity based on the bandwidth resource adjustment transaction and a preset intelligent contract, wherein the third resource quantity is the sum of the second resource quantity and the preset resource quantity, and the second network system can compensate the reduced bandwidth resource of the first network system for the user terminal through the interaction of the first network system and the second network system, so that the first network system and the second network system can jointly provide stable bandwidth resource for the user terminal, the stability of data connection of the user terminal is improved, and the user experience is ensured.

In an implementation scenario, when a user terminal uses a service that has a certain requirement on a network bandwidth, for example, a live video service that performs compression coding at a fixed coding rate, the user terminal needs to maintain a certain (downlink) network bandwidth during the service usage process, so that the user experience is not affected by a bandwidth change (reduction). However, due to the influence of factors such as the location change of the ue, the coverage of different mobile communication networks, and the signal strength of the same mobile communication network in different coverage, the ue may encounter the situation that the bandwidth resource of the connected first network system is insufficient during the service usage process, which may cause the ue to obtain only a lower bandwidth and thus reduce the service quality (for example, watch a low-bit rate live video), or even cause the whole data link of the ue to be disconnected, thereby reducing the user experience. By the bandwidth resource adjusting method provided by the embodiment of the invention, the first network system and the second network system can provide stable bandwidth resources for the user terminal together, the stability of data connection of the user terminal is improved, and the user experience is ensured.

Fig. 2 is a flowchart of another bandwidth resource adjustment method according to an embodiment of the present invention, which is applied to a second network system. The user terminal establishes communication connection with a first network system and a second network system, the first network system provides bandwidth resources with a first resource amount for the user terminal, and the second network system provides bandwidth resources with a second resource amount for the user terminal. As shown in fig. 2, the bandwidth resource adjustment method includes the following steps:

step S201, receiving a bandwidth resource adjustment transaction sent by the first network system.

The bandwidth resource adjustment transaction is a transaction generated by the first network system based on the preset intelligent contract and the preset resource amount after determining the preset resource amount aiming at the user terminal based on the first resource amount in response to the predicted available resource amount being smaller than the first resource amount.

In one embodiment, the second network system, prior to receiving the bandwidth resource adjustment transaction sent by the first network system, comprises: and receiving second multi-path connection reminding information sent by the user terminal. And the second multi-path connection reminding information comprises a network identifier of the first network system. The second multi-path connection reminding information is used for indicating that the user terminal currently establishes a multi-path connection, and the other sub-connection in the multi-path connection is carried by the first network system.

In one embodiment, after receiving the second multi-path connection reminding information, the second network system extracts the terminal identifier of the user terminal and the network identifier of the first network system from the second multi-path connection reminding information, and stores the terminal identifier of the user terminal and the network identifier of the first network system in an associated manner.

In one embodiment, a bandwidth resource adjustment transaction received by the second network system from the first network system has a signature of the first network system. The second network system may verify the signature of the first network system based on the public key of the first network system, and in case that the signature of the first network system is verified to pass, perform the following step S202.

Step S202, based on the bandwidth resource adjustment transaction and the preset intelligent contract, adjusting the resource quantity of the bandwidth resource provided for the user terminal from the second resource quantity to a third resource quantity.

Wherein the third resource amount is the sum of the second resource amount and the pre-adjusted resource amount. The preset intelligent contract is an intelligent contract preset in the block chain network. The blockchain network includes a first blockchain network and a second blockchain network. The first blockchain network is a blockchain network in which the first network system, the second network system and the user terminal are located. The second blockchain network is a blockchain network in which the first network system and the second network system are located, and nodes of the second blockchain network do not include the user terminal.

Fig. 3 is a flowchart of a specific implementation manner of step S202 according to an embodiment of the present invention. In one embodiment, as shown in fig. 3, the step of adjusting the resource amount of the bandwidth resource provided for the user terminal from the second resource amount to the third resource amount based on the bandwidth resource adjustment transaction and the preset intelligent contract (step S202) includes:

and S301, signing the bandwidth resource adjustment transaction based on the preset intelligent contract.

In this step, the bandwidth resource adjustment transaction already has the signature of the first network system, and after the second network system executes step S301, the bandwidth resource adjustment transaction signed by the second network system has both the signature of the first network system and the signature of the second network system.

Different network systems have different charging standards for network resources, and after the first network system interacts with the second network system, the second network system needs to be confirmed by the user terminal before providing additional resources for the user terminal, so the second network system performs the following step S302.

Step S302, the bandwidth resource adjustment transaction signed by the second network system is sent to the user terminal, so that the user terminal signs the bandwidth resource adjustment transaction and broadcasts the bandwidth resource adjustment transaction signed by the terminal to the first block chain network.

The first blockchain network is a blockchain network in which the first network system, the second network system and the user terminal are located at the same time.

In one embodiment, after receiving the bandwidth resource adjustment transaction sent by the second network system, the user terminal verifies the signature of the first network system and the signature of the second network system included in the bandwidth resource adjustment transaction, for example, the signature of the first network system is verified by using the public key of the first network system, and the signature of the second network system is verified by using the public key of the second network system. And under the condition that the signature of the first network system and the signature of the second network system are both verified to be correct, the user terminal signs the bandwidth resource adjustment transaction and broadcasts the bandwidth resource adjustment transaction signed by the user terminal to the first block chain network. Wherein the terminal signed bandwidth resource adjustment transaction has simultaneously the signature of the first network system, the signature of the second network system and the signature of the user terminal.

In one embodiment, after the user terminal signs the bandwidth resource adjustment transaction and broadcasts the terminal-signed bandwidth resource adjustment transaction to the first blockchain network, the second network system receives the resource adjustment transaction broadcast by the user terminal in the first blockchain network and verifies the resource adjustment transaction broadcast by the user terminal in the first blockchain network. For example, the second network system verifies the signature of the first network system, the signature of the second network system, and the signature of the user terminal included in the bandwidth resource adjustment transaction signed by the terminal, respectively.

And the second network system confirms that the resource adjustment transaction broadcasted by the user terminal in the first block chain network does not pass under the condition of verifying that any one of the signature of the first network system, the signature of the second network system and the signature of the user terminal is incorrect, and the second network system sends prompt information of error of the bandwidth resource adjustment transaction to the user terminal.

And the second network system confirms that the resource adjustment transaction broadcasted by the user terminal in the first block chain network passes the verification under the condition that the signature of the first network system, the signature of the second network system and the signature of the user terminal are all verified to be correct.

Step S303, in the case of verifying that the resource adjustment transaction broadcasted by the ue in the first blockchain network passes, adjusting the resource amount of the bandwidth resource provided for the ue from the second resource amount to a third resource amount.

Fig. 4 is a flowchart of another specific implementation manner of step S202 according to an embodiment of the present invention. In another embodiment, as shown in fig. 4, the step of adjusting the resource amount of the bandwidth resource provided for the user terminal from the second resource amount to the third resource amount based on the bandwidth resource adjustment transaction and the preset intelligent contract (step S202) includes:

step S401, generating an adjustment condition transaction and an adjustment compensation transaction based on the bandwidth resource adjustment transaction and the preset intelligent contract.

Wherein the bandwidth resource adjustment transaction includes the amount of the pre-adjusted resource and a network identification of the second network system. The data format of the bandwidth resource adjustment transaction is as follows: t1{ [ N2], [ r → UE ] }. Wherein, T1 refers to a bandwidth resource adjustment transaction; n2 refers to the second network system, r refers to the amount of pre-adjusted resources, and UE refers to the user terminal. N2 may be represented by a network identifier of the second network system, and the UE may be represented by a terminal identifier of the user terminal. [ N2] is an input of a bandwidth resource adjustment transaction T1, indicating that the bandwidth resource corresponding to the pre-adjusted resource amount r is provided by the own bandwidth resource of the second network system N2. [ r → UE ] is an output of the bandwidth resource adjustment transaction T1, indicating that the second network system N2 allocates the bandwidth resource corresponding to the pre-adjusted resource amount r to the user terminal UE.

In one embodiment, the adjusted condition transaction generated by the second network system includes the amount of the pre-adjusted resource, the network identification of the second network system, and a transaction fulfillment condition. The data format of the adjustment condition transaction is as follows: t3{ [ N2], [ r → UE ] | T4in-Chain-P }.

Wherein, T3 refers to adjustment condition trading; n2 refers to the second network system, r refers to the amount of pre-adjusted resources, UE refers to the user terminal, T4 refers to the adjustment back-off transaction, P refers to the second blockchain network. N2 may be represented by a network identifier of the second network system, and the UE may be represented by a terminal identifier of the user terminal. [ N2] is an input of the adjustment condition trade T3, which indicates that the bandwidth resource corresponding to the pre-adjustment resource amount r is provided by the own bandwidth resource of the second network system N2. [ r → UE ] is an output of the adjustment condition transaction T3, and indicates that the second network system N2 allocates the bandwidth resource corresponding to the pre-adjustment resource amount r to the user terminal UE. "|" identifies the transaction content and the separator of the transaction fulfillment condition. "T4 in-Chain-P" is a transaction fulfillment condition, which means that the adjustment condition transaction T3 can only be validated after the adjustment compensation transaction T4 is validated in the second blockchain network P.

In one embodiment, the adjustment compensation transaction generated by the second network system includes an amount of compensation resources, a network identification of the first network system, and a network identification of the second network system. The data format of the adjustment compensation transaction is: t4{ [ N1], [ c → N2] }.

Wherein T4 refers to adjustment compensation transactions; n1 refers to the first network system; n2 refers to the second network system; c is the amount of compensation resources, such as the amount of funds. Wherein N1 may be represented by a network identification of the first network system; n2 may be represented by a network identification of the second network system. [ N1] is the input of the adjustment compensation transaction T4, which indicates that the compensation resource corresponding to the compensation resource amount c is the own resource of the first network system N1, such as the own fund of N1. [ c → N2] is the output of the adjustment trade T4, which means that the first network system N1 sends the compensation resource corresponding to the compensation resource amount c to the second network system N2, for example, the first network system N1 pays the fund corresponding to the fund amount c to the second network system N2.

In one embodiment, after the second network system generates the adjustment condition transaction and the adjustment compensation transaction, the adjustment condition transaction and the adjustment compensation transaction are signed respectively, and the following step S402 is performed after the signature.

Step S402, the adjustment condition transaction and the adjustment compensation transaction are sent to a first network system, so that the first network system signs the adjustment condition transaction and the adjustment compensation transaction, broadcasts the adjustment compensation transaction signed by the first network system to a second block chain network, and sends the adjustment condition transaction signed by the first network system to a user terminal.

In one embodiment, the first network system verifies the adjusted conditional transaction and the adjusted compensation transaction, respectively, after receiving the adjusted conditional transaction and the adjusted compensation transaction sent by the second network system. For example, the signature of the second network system included in the adjustment condition transaction and the signature of the second network system included in the adjustment compensation transaction are respectively verified by using the public key of the second network system. And under the condition that the signature of the second network system included in the adjustment condition transaction and the signature of the second network system included in the adjustment compensation transaction are both verified to pass, the user terminal confirms that the adjustment condition transaction and the adjustment compensation transaction pass, signs the adjustment condition transaction and the adjustment compensation transaction by the user terminal, broadcasts the adjustment compensation transaction signed by the first network system to the second block chain network, and sends the adjustment condition transaction signed by the first network system to the user terminal.

It should be noted that since the adjustment compensation transaction only involves the first network system and the second network system, the adjustment compensation transaction can be established without a user terminal signature. Moreover, to fulfill the security requirements of the operator, for example, the requirement that the amount of compensation resources sent by the first network system to the second network system needs to be secured to the user terminal, the first network system may broadcast the adjusted compensation transaction signed by the first network system to the second blockchain network. The node of the second blockchain network comprises the first network system and the second network system, but does not comprise the user terminal.

In one embodiment, a user terminal receives a first network system signed conditioned transaction sent by a first network system and verifies the conditioned transaction. For example, the user terminal verifies the signature of the first network system included in the adjusted conditional transaction using the public key of the first network system, and verifies the signature of the second network system included in the adjusted conditional transaction using the public key of the second network system. And the user terminal confirms that the adjustment condition transaction is not verified under the condition that the signature of the first network system is verified to be incorrect or the signature of the second network system is verified to be incorrect, and returns an error prompt message for the adjustment condition transaction to the first network system.

And the user terminal confirms that the adjustment condition transaction passes verification under the condition that the signature of the first network system and the signature of the second network system are both correct, signs the adjustment condition transaction and broadcasts the adjustment condition transaction signed by the user terminal to the first block chain network. Wherein the adjusted conditional transaction signed by the user terminal and broadcast to the first blockchain network has the signature of the second network system, the signature of the first network system and the signature of the user terminal at the same time.

In one embodiment, the second network system receives and verifies the adjusted condition transaction broadcast by the user terminal in the first blockchain network. For example, the second network system verifies the signature of the first network system included in the adjustment conditional transaction using the public key of the user terminal, verifies the signature of the first network system included in the adjustment conditional transaction using the public key of the first network system, and verifies the signature of the second network system included in the adjustment conditional transaction using its own public key. When any one of the signature of the user terminal, the signature of the first network system and the signature of the second network system is verified to be incorrect, the second network system confirms that the adjusted conditional transaction is not verified to pass, and the second network system discards the adjusted conditional transaction. And the second network system confirms that the transaction of the adjustment condition is verified to pass under the condition that the signature of the user terminal, the signature of the first network system and the signature of the second network system are all correct.

In one embodiment, the second network system receives and verifies that the first network system broadcasts an adjustment compensation transaction on the second blockchain network.
