Description

The present invention claims the priority of Chinese Patent Application No. 201811160657.9 filed with the Chinese Patent Office on September 30, 2018 titled "Data Processing Method and Data Processing Apparatus", which is incorporated herein by reference in its entirety.

The field of technology to which the invention belongs

The present invention relates to the field of communication and, in particular, to a data processing method and a data processing device.

State of the art

Briefly, typical satellite communications are communications performed by radio stations on earth using satellites as repeaters. A satellite communication system typically includes three parts: a space segment, a ground segment, and a user segment. The space segment typically represents communications satellites, the ground segment typically controls centers or various gateways, and the user segment typically represents the terminals.

As shown in Fig. 1, when a terminal device performs satellite handover, for example, a terminal device handoff is performed from a source satellite to a target satellite, firstly, the terminal device must send a handover request to the target satellite to complete a sequence of operations such as measurement reporting, handover decision and radio resource control (RRC) configuration. The target satellite sends a path switch request to the ground segment gateway and receives an acknowledgment message fed back by the gateway. The source satellite can release the network resource only after the gateway acknowledges the path switch request. Thus, the handover process of the satellite is completed. Subsequently, the data sent by the main network is transmitted by the target satellite to the terminal device, but is not forwarded by the source satellite to the terminal device.

Obviously, when a terminal device performs satellite handover, the satellite handover process can only be completed after the path switch request between the space segment satellite device and the terrestrial segment gateway device has been acknowledged. However, the handover of the satellite is usually performed frequently. In this case, information must be exchanged frequently between satellites and gateways. This causes significant network overhead.

The fact that the tag is idle in the target cell may be that the tag accesses the target cell after performing a cell handover or cell update, or that the tag updates the location to the target cell after performing a location update. In the present document, this aspect is not specifically limited.

It should be noted that a possible case of the data to be verified is that the data to be verified is idle mode information of the terminal.

202. The first communication node sends the data to be verified to the second communication node.

The first communication node signs the data to be verified with a private key and then broadcasts the data to be verified to the second communication node. The second communication node performs decryption using the public key of the first communication node to obtain data to be verified. Then, the second communication node verifies the data to be verified using the idle state statistics of the terminal device, which is stored in the corresponding second node of the blockchain, to obtain a verification result.

If the result of the verification is a successful verification, the second communication node stores the data to be verified in the local storage unit of the second communication node.

The idle mode statistics information is a set of idle mode information of a terminal device when the terminal device is idle at the first site or the second site at any or more times before the terminal is idle at the first site in the present invention.

203: The first communication node receives the target block if the verification result is a successful verification.

The first communication node obtains the target block if the verification result of the second communication node of the data to be verified is a successful verification.

In this embodiment, the data to be verified is sent between the first communication node and the second communication node. Each node in the blockchain can receive the verification result after verifying the data to be verified. This is equivalent to the process of completing the verification of the data to be verified using the blockchain. After receiving the verification result, the end device can go to sleep mode in the target cell without the participation of the gateway. Therefore, in the present invention, the terminal device can enter the sleep mode in the target cell only using the interaction between the first site and the second site, and communication between the satellite and the terrestrial gateway is not required, thereby reducing the network overhead.

In this embodiment, the first communication node obtains the target block in a variety of ways. One of the blockchain nodes is determined with or without contention, and the communication node corresponding to the blockchain node generates the target block. Therefore, the target block may be generated by the first communication node or may be generated by the second communication node. Referring to Fig. 3(a) and Fig. 3(b), two cases are described below.

1. Referring to FIG. 3(a), a description is given of a case in which the first communication node generates a target block.

301. The first communication node receives the data to be verified.

302. The first communication node sends the data to be verified to the second communication node.

Steps 301 and 302 in this embodiment are the same as steps 201 and 202 in the above embodiment. The details are again not described.

303. The second communication node verifies the data to be verified.

The method in which the second communication node verifies, the data to be verified, and the value of the idle mode statistics information is similar to the above step 202. Details are not described.

304: If the verification result is a successful verification, the first communication node generates a target block based on the data to be verified.

If the verification result is a successful verification, after a timer expiration time, the processor in the data processing system determines that the first communication node should generate a target block, and the first communication node generates a target block based on all the data to be verified that is successfully verified within this period.

Perhaps the first communication node verifies the hash value (hash) of the target block and adds the target block to the first node of the blockchain after successful verification.

If the result of the verification is verification failure, the first communication node and the second communication node delete the data to be verified stored in the local storage units.

Possibly, if the verification result is a successful verification, then the second communication node may further send the verification result to the first communication node, so that the first communication node generates a target block based on the successful verification message after receiving the successful verification message, or the first communication node may directly generate target block without receiving a successful verification message. This is not specifically limited in the present invention.

305: The first site broadcasts the target block to the second site.

After generating the target block, the first communication node translates the target block to the second communication node.

306: The second communication node adds the target block to the blockchain.

The second communication node verifies the hash value of the target block, and after successful verification, adds the target block to the blockchain maintained by the second blockchain node.

2. Referring to FIG. 3(b), a description is given of a case in which the second communication node generates a target block.

301. The first communication node receives the data to be verified.

302. The first communication node sends the data to be verified to the second communication node.

Steps 301 and 302 in this embodiment are the same as steps 201 and 202 in the above embodiment. The details are again not described.

303. The second communication node verifies the data to be verified.

The method in which the second communication node verifies, the data to be verified, and the value of the idle mode statistics information is the same as in the above step 202. Details are not described.

304: If the verification result is a successful verification, the second communication node generates a target block based on the data to be verified.

If the result of the verification is a successful verification, after the timer expires, the processor in the data processing system determines that the second communication node generates a target block and the second communication node generates a target block based on all data to be verified that is successfully verified during the period.

Perhaps the second communication node verifies the hash value of the target block and adds the target block to the second blockchain node after successful verification.

If the result of the verification is an unsuccessful verification, the first communication node and the second communication node delete the data to be verified stored in the local storage units.

305: The second site broadcasts the target block to the first site.

After generating the target block, the second communication node translates the target block to the first communication node.

306: The first communication node adds the target block to the blockchain.

The first communication node verifies the hash value of the target block and adds the target block to the first blockchain node after successful verification.

In this embodiment, after one of the blockchain nodes is determined in a contention or non-contention manner, the communication node corresponding to the blockchain node generates a target block, and the target block can be used to verify the data to be verified in the next period when the target end the device is idle in the cell served by the communication node again in the next period.

The present invention may be applied to a cell handover scenario, or may be applied to a tag location update scenario. Two scenarios are described below.

Referring to FIG. 4, the following is a description of an embodiment of the present invention based on a cell handover scenario.

401: The first communication node receives data to be verified when the terminal device performs a handover to the target cell.

When the terminal device needs to perform a handover from a cell in the signal coverage area of the source site to a cell in the signal coverage area of the first site, first of all, the source site sends a handover request to the first site to request the handover of the cell. The first communication node feeds back a handover response identifier to allow access to the terminal. The terminal device then performs a cell handover.

In this embodiment, the source communication node is any communication node in the data processing system other than the first communication node.

Step 401 in this embodiment is the same as step 201 in the above embodiment. It should be noted that the idle mode information is specifically a handover record of the terminal device and includes: information of the terminal device such as the identity (ID) of the cell in which the terminal device is located before the handover, the node ID of the cell in which the terminal the device is located after the handover, the handover time, and the terminal capabilities received by the first communication node.

402. The first communication node sends the data to be verified to the second communication node.

Step 402 in this embodiment is similar to step 202 in the above embodiment. The details are again not described.

403. The second communication node verifies the data to be verified based on the second blockchain node.

The second communication node verifies the data to be verified based on the idle history information in the second blockchain node, and the idle history information is specifically a handover history record. There are several possible verification cases, and two cases are used as examples to describe, as follows:

A. The second communication node first determines the cell information, which is the cell in which the terminal device is idle before handover, that is, in the handover history record, then determines the cell information, which is the cell in which the terminal device is in standby until handover, i.e. in the data to be verified, and determines whether the cell information in the handover statistics record matches the cell information in the data to be verified. If the cell information in the handover history record matches the cell information in the data to be verified, the second communication node determines that the result of the verification is a successful verification; or, if the cell information in the handover history record does not match the cell information in the data to be verified, the second communication node determines that the verification result is a verification failure.

In this embodiment, the information about the cell in which the terminal is idle before handover may be an identifier of the cell in which the terminal is located before handover, may be the service level of the cell in which the terminal is located before handover, or may be other information about the cell in which the terminal is located before the handover. This is not specifically limited.

For example, from the data to be verified, it is possible to extract information that the terminal device performs a handover from cell A to cell B. If information is obtained from the handover statistics record that the terminal device is also in cell A before the handover, the result of verification is successful verification. If it is learned from the handover statistics record that the terminal is in cell C before the handover, and therefore the handover record that the terminal performs a handover from cell A to cell B is invalid, the result of the verification is a failed verification. For another example, from the data to be verified, information is obtained that the terminal device performs a handover from cell A to cell B, and the service level of the terminal device in cell A is the highest priority. If information is obtained from the handover statistics record that the service level of the terminal in cell A is also the highest priority, the verification result is a successful verification. If information is obtained from the handover statistic record that the service level of the terminal device in cell A is the second highest priority, and therefore the handover record that the terminal device performs handover from cell A to cell B is invalid, the verification result is a failed verification.

B. The second communication node determines, based on the data to be verified, that the terminal device performs a handover to the target cell, the authority level in the handover statistic record that the target cell is allowed to access, determines the authority level of the terminal device in the data to be verified, or statistic handover entry and determines, based on two levels of authority, whether the target device is allowed to access the target cell. If the target device has permission to access the target cell, the verification is successful; otherwise, verification is not performed. For example, from the data to be verified, it can be learned that the terminal device performs a handover from cell A to cell B, and from the handover statistics record, it can be learned that the terminal device in cell B has a higher access level than the access level granted to the terminal device , and the endpoint's privilege level is not increased. Therefore, the handover record that the terminal performs a handover from cell A to cell B is not valid, and the verification result is a verification failure.

404: The first communication node receives the target block if the verification result is a successful verification.

Step 404 of this embodiment is similar to step 203 in the above embodiment. The details are again not described.

After the first communication node receives the target block, the source node releases the network resource, the first communication node allocates the network resource to the end device, and the handover is completed.

In the present invention, the terminal cell handover process can only be completed using the interaction between the first site and the second site, and data interaction between the satellite and the terrestrial gateway is not required, thereby reducing network overhead.

Referring to FIG. 5, the following is a description of an embodiment of the present invention based on a scenario in which a terminal accesses a target cell after performing a location update.

501: The first communication node receives data to be verified when the tag's location is updated to the target cell.

The tag first obtains system information of the available cell to determine the current location of the tag, and then determines, based on the current location, whether the location update of the tag has been completed. If the tag performs a location update, for example, the tag moves from city A to city B, the tag initiates a random access process to the first site, establishes an RRC connection, and sends a location update request to the first site. After the terminal accesses the target cell, the first communication node generates data to be verified based on the idle mode information.

Step 501 in this embodiment is the same as step 201 in the above embodiment. It should be noted that the idle mode information is specifically information such as tag ID, idle time, and tag capabilities.

502. The first communication node sends the data to be verified to the second communication node.

Step 502 in this embodiment is similar to step 202 in the above embodiment. The details are again not described.

503. The second communication node verifies the data to be verified based on the second blockchain node.

The second communication node verifies the data to be verified based on the idle history information in the second blockchain node, and the idle history information is specifically the location update history information. A specific verification method may be as follows:

The second communication node determines, based on the data to be verified, that the terminal device performs a handover to the target cell, determines the authority level in the handover statistics record that access to the target cell is allowed, determines the authority level of the terminal device in the data to be verified, or in the statistical handover entry and determines, based on two levels of authority, whether the terminal device has permission to access the target cell. If the target device has permission to access the target cell, the verification is successful; otherwise, verification is not performed. For example, from the data to be verified, it can be learned that the terminal device is handover from cell A to cell B, and from the handover statistics record, it can be learned that the access level of the terminal device in cell B is higher than the access level granted to the terminal device, and the target device's privilege level is not raised. Therefore, the handover record that the terminal performs a handover from cell A to cell B is not valid, and the verification result is a verification failure.

504: The first communication node receives the target block if the verification result is a successful verification.

Step 504 of this embodiment is similar to step 203 in the above embodiment. The details are again not described.

After the first communication node receives the target block, the first communication node allocates a network resource to the tag, and the location update of the tag is completed.

In the present invention, the cell definition update process of the terminal device can only be completed using the interaction between the first site and the second site, and communication between the satellite and the terrestrial gateway is not required, thereby reducing the network overhead.

Referring to Fig.6, the following is a description of an embodiment of the present invention in relation to the second communication node.

601. The second communication node receives data to be verified sent by the first communication node.

Step 601 in this embodiment is the same as step 201 in the above embodiment. The details are again not described.

602. The second communication node verifies the data to be verified based on the second blockchain node to obtain a verification result.

The method in which the second communication node verifies the data to be verified is the same as in the above step 202. Details are not described again.

Similarly, for a tag handover scenario and a tag location update scenario in which the second communication node verifies the data to be verified, reference can be made to the embodiments of FIG. 4 and FIG. The details are again not described.

603: The second communication node receives the target block if the verification result is a successful verification.

Similarly, the target block may be generated by the first communication node and then sent to the second communication node, or may be generated by the second communication node. Refer to the embodiments in Figure 3(a) and Figure 3(b). The details are again not described.

The present invention further provides a data processing method that can be applied to a network access authentication process of a terminal device, as described below.

In a scenario in which the terminal device needs to perform authentication, for example, when the terminal device is turned on, performs a location update or network access for the first time, each communication node in the data processing system verifies the network access authentication data of the terminal device. When an end device accesses the network for the first time, after successfully verifying the network access authentication data of the end device, each communication node generates a target block and adds the target block to the corresponding blockchain node. When the terminal accesses the network not for the first time, each communication node can verify the network access authentication data of the terminal device using the network access authentication statistics stored in the blockchain node corresponding to the communication node. With reference to Fig.7(a), the following is a description of the method.

701. The first communication node receives the data to be verified.

After the terminal device enters the sleep mode in the target cell, since the target cell is a cell in the signal coverage area of the first communication node, the first communication node supplies public key information to the terminal device so that the terminal device is able to encrypt the public key information of the terminal device. device and the ID of the terminal device using the public key of the first communication node, and feeds back the public key information of the terminal device and the identifier of the terminal device to the first communication node. Then, the first communication node performs decryption using the private key of the first communication node to obtain the public key of the terminal device, encrypts the session information using the public key of the terminal device, and then sends the encrypted session information to the terminal device. The end device performs decryption with the end device's private key to obtain a session key. The terminal device encrypts the information of the terminal device using the session key and sends the encrypted information of the terminal device to the first communication node.

The tag information includes tag information such as network access authentication data and tag capabilities. The data to be verified is the network access authentication data. After receiving the data to be verified, the first communication node stores the data to be verified in a local storage unit.

When the terminal accesses the network for the first time, the method includes:

702. The first communication node verifies the data to be verified.

The first communication node verifies the network access authentication data of the terminal device and determines whether the terminal device has permission to access the network. If the terminal device has permission to access the network, the verification result is a successful verification, and the first communication node stores the data to be verified in the local storage unit of the first communication node; otherwise, the verification result is a failed verification.

703. The first communication node sends the data to be verified to the second communication node if the verification result of the first communication node is a successful verification.

If the verification result of the first communication node is a successful verification, the first communication node signs the data to be verified with a private key and then broadcasts the data to be verified to the second communication node. The second communication node performs decryption using the public key of the first communication node to obtain data to be verified.

704. The second communication node verifies the data to be verified.

The second communication node verifies the network access authentication data of the terminal device and determines whether the terminal device has permission to access the network. If the terminal device has permission to access the network, the verification result is successful verification, the second communication node stores the data to be verified in the local storage unit of the second communication node; otherwise, the verification result is a failed verification.

705. The first communication node receives the target block if the second communication node's verification result is a successful verification.

Step 705 in this embodiment is similar to step 203 in the above embodiment. One of the blockchain nodes is determined in a competitive way or in a non-competitive way, and the communication node corresponding to the blockchain node generates the target block. Therefore, the target block received by the first communication node may be generated by the first communication node or may be generated by the second communication node. The details are again not described.

After generating the target block, the first communication node and the second communication node each add the target block to the corresponding blockchain node, so that when the end device gains network access again, each blockchain node can verify the end device's network access authentication data using the stored target block. .

Alternatively, when the terminal is not accessing the network for the first time, referring to FIG. 7(b), the method includes the following steps.

701. The first communication node receives the data to be verified.

The step in this embodiment is the same as step 701 in the embodiment in FIG. 7(a). The details are again not described.

702. The first communication node verifies the data to be verified based on the first blockchain node.

In this embodiment, the first blockchain node stores network access authentication statistics, and the network access authentication data may be a target block that is stored in the blockchain node when the end device accesses the network for the first time.

The first communication node verifies the network access authentication data of the terminal device and determines whether the terminal device has permission to access the network, which in particular is: the first communication node determines whether the network access authentication data of the terminal device is stored in the access authentication statistics to the network; if the network access authentication data of the terminal device is stored in the network access authentication statistics, the verification result is successful verification, and the first communication node stores the data to be verified in the local storage unit of the first communication node; otherwise, the verification result is a failed verification.

703. The first communication node sends the data to be verified to the second communication node if the verification result of the first communication node is a successful verification.

If the verification result of the first communication node is a successful verification, the first communication node signs the data to be verified with a private key, and then broadcasts the data to be verified to the second communication node. The second communication node performs decryption using the public key of the first communication node to obtain data to be verified.

704. The second communication node verifies the data to be verified based on the second blockchain node.

In this embodiment, the second blockchain node also stores network access authentication statistics.

The second communication node verifies the network access authentication data of the terminal device, and determines whether the terminal device has permission to access the network, in particular, is: the second communication node determines whether the network access authentication data of the terminal device is stored in the access authentication statistics to the network; if the network access authentication data of the terminal device is stored in the network access authentication data, the verification result is successful verification, and the second communication node stores the data to be verified in the local storage unit of the second communication node; otherwise, the verification result is a failed verification.

705. The first communication node receives the target block if the second communication node's verification result is a successful verification.

Step 705 in this embodiment is similar to step 203 in the above embodiment. One of the blockchain nodes is determined in a contention-based or non-competitive manner, and a communication node corresponding to the blockchain node generates a target block. Therefore, the target block received by the first communication node may be generated by the first communication node or may be generated by the second communication node. The details are again not described.

It can be understood that the data processing methods shown in FIG. 7(a) and FIG. 7(b) apply to, but are not limited to, the tag authentication scenario, and other cases similar to the tag authentication scenario are also within the protection of this inventions.

Obviously, in the present invention, the target block is generated when the end device accesses the network for the first time, and is added to the blockchain node when the end device accesses the network not for the first time, the end device authentication process can only be completed using the interaction between the first communication node and the second communication node, and communication between the satellite and the terrestrial gateway is not required, thereby reducing network overhead.
