Detailed Description
The core of the invention is to provide a 5G data transmission method, which utilizes a plurality of mutually isolated slices to transmit different parts of data without mutual influence, can greatly improve the security and confidentiality of data transmission and improve the service experience of users; the other core of the invention is to provide a 5G data transmitting device, a 5G data receiving device and a 5G data transmission system.
In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, but not all, embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
The first embodiment is as follows:
referring to fig. 1, fig. 1 is a signaling diagram of a 5G data transmission method provided in this embodiment; the method mainly comprises the following steps:
and step s111, the sender acquires the data splitting transmission rule.
And step s121, the receiver acquires the data splitting transmission rule.
The data splitting transmission rule is determined according to the security level of the data to be transmitted. The security level to be transmitted is the security level of the data to be transmitted, the security level can be generally determined according to the type of the data to be transmitted, if the data to be transmitted is research and development files and the like, a high security level can be set, for example, the security level comprises a common level, a secret level and an absolute level, and when the security level is sequentially increased, the current security level to be transmitted can be set to be the absolute level.
The security levels corresponding to different data are generally different, and the corresponding data splitting and transmission rules naturally have certain differences. In this embodiment, the data splitting transmission rule is obtained according to the security level of the data to be transmitted, a specific determination method is not limited, the security level to be transmitted can be determined according to the identifier type of the important level of the data, the formats, types, naming modes and the like of different data are possibly different, a problem exists in the possible stability of the method for determining the security level through the data identifier, and in order to avoid the situations of data security reduction and the like caused by selection of an inappropriate transmission mode, preferably, the data transmission security level can be negotiated by two communication parties, so that the data splitting transmission rule is further determined, and specifically, a sender accesses an initial network slice; carrying out security level negotiation with a receiver simultaneously connected with the initial network slice according to the data to be transmitted to obtain a security level to be transmitted; and configuring a data splitting transmission rule corresponding to the security level to be transmitted by the receiver. The two communication parties establish signaling connection through the initially accessed slice, then the two communication parties negotiate to determine the security level of the subsequent data to be transmitted, the two communication parties negotiate and set the security level before transmission of each data to be transmitted, and the corresponding security level is matched for each data packet to be transmitted, so that the adjustment of the adaptive transmission mode of each data packet is realized as much as possible.
The data splitting transmission rule is how a sender decomposes a complete original data packet into different small parts, and then how the small parts are respectively transmitted by using different network slices, and mainly comprises: the data splitting rule and the transmission slice identification of each split data segment.
The higher the security level is, the higher the data restoration difficulty after the data splitting mode is, and the more the required network slices are likely to be. When the security level is higher, more slices can be selected and used, and the data is divided into more parts, so that the data volume transmitted in each slice is ensured to be less, and even if the data transmitted in a certain slice is illegally acquired, the lost data volume is less; in addition, a complex data splitting rule may be set, for example, when the security level is low, splitting may be performed directly according to the number of bytes (for example, when the data of 100 bytes in total needs to be split into two slices for transmission, the first 50 bytes) or split into odd-byte data and even-byte data, etc., when the security level is high, a splitting rule determined only by both communication parties may be set, and through the complex data splitting rule, even if some slice data is intercepted, the obtained data is not consistent, and useful information cannot be obtained therefrom.
Specifically, the process of configuring the corresponding data splitting transmission rule according to the security level is not limited, and the data splitting transmission rule corresponding to the security level to be transmitted in the configuration table can be queried to determine the data splitting transmission rule of the data to be transmitted; the configuration table is preset by both communication parties, and data splitting and transmission rules corresponding to various types of security levels are stored in the configuration table in advance. The two communication parties preset configuration tables, wherein the configuration tables have corresponding relations between security levels and the number of network slices, specific slice information (such as slice identifiers) and data splitting and transmitting modes, which network slices need to be used at the same time and how data transmission is split can be found from the configuration tables according to the security levels determined in the first step, different communication parties can configure different configuration tables, the configuration tables are set according to the individuation of the communication parties, a controllable adaptive scheme can be selected on the premise of enhancing the data security through the query of the configuration tables, and the efficiency of the rule determining process is improved. One configuration table is shown in table 1 below.
Figure BDA0001854134200000071
TABLE 1
For example, when the security level of the data to be transmitted is a security level, one rule may be determined from the rules 31 and 32 as a determined data splitting transmission rule (for example, the rule 31 that only needs two slices may be determined according to the number and type of available slices as a determined rule, etc.).
In addition, the data splitting transmission mode can be determined through the slice manager, so that the resource occupation determined by the data splitting transmission rule is improved, the determination time is shortened, and specifically, the security level to be transmitted, the available network slice resource information and the user identifications of the two communication parties can be sent to the slice manager; and receiving a data splitting transmission rule returned by the slice manager. For example, the communication party sends the previously determined security level, the user identifications of the two parties and the currently accessed initial slice information to the slice manager, the slice manager determines which network slices and data splitting transmission modes need to be used simultaneously, and then the slice manager returns the related information to the communication parties. The resources of both communication parties are not occupied, and the method is convenient and quick.
After the sender and the receiver determine the splitting transmission rule of the data, the sender carries out corresponding splitting and network slice transmission on the data to be transmitted, and the receiver carries out corresponding combination reduction on the received data. If the sender splits the complete 100 bytes of data into 4 parts, the first part of data is the original 1 st, 5 th and 9 th 9 … 97 th bytes; the second part is the original 2 nd, 6 th and 10 … 98 th bytes, and so on, then the 4 parts of data are transmitted through 4 different slices respectively (for example, slice 1 transmits the first part of data, slice 2 transmits the second part of data … …), and the receiver performs reverse combination restoration according to the negotiated rule after receiving the data, and the original data packet can be obtained.
The determined data splitting transmission rule informs the sending end and the transmission end, the sending end correspondingly splits and transmits the data to be transmitted to the receiving end after determining the data splitting transmission rule, and the receiving end determines the data splitting transmission rule so as to restore the data after receiving the data.
And step s112, the sender accesses the network slice corresponding to the transmission slice identifier and obtains slice information to obtain the sender slice information.
And step s122, the receiver accesses the network slice corresponding to the transmission slice identifier, and obtains slice information to obtain the slice information of the receiver.
The transport network slices (mainly slice identities) determined according to the data splitting transmission rule access the network slices, such as slice 1, slice 2, slice 3, and slice 4. When both communication parties determine the data splitting transmission mode, both communication parties simultaneously connect to the initial network slice 1, and at this time, the sender and the receiver only need to connect to the slice 2, the slice 3 and the slice 4.
The terminal respectively obtains slice information from each accessed network slice, wherein the slice information comprises: and accessing slice IP and port information.
And step s113, the sender transmits the sender slice information to the receiver and records the received receiver slice information.
And step s123, the receiving party transmits the slice information of the receiving party to the sending party and records the received slice information of the sending party.
The two communication parties access more slices according to the negotiation result, and exchange the IP address and port number information of the two parties in each slice, so as to prepare for transmitting different parts of data through the slices.
And step s114, the sender splits the data to be transmitted according to the data splitting rule to obtain a plurality of data segments.
And step s115, the sender transmits the data segment through the corresponding network slice according to the slice information of the receiver.
The sender splits an original data into a plurality of different parts according to the negotiated data splitting transmission mode, and then simultaneously transmits the different parts of the data by using a plurality of slices according to the negotiated data splitting transmission mode.
The characteristics that the network slices are isolated from each other and not mutually influenced are utilized, so that both communication parties can simultaneously access a plurality of same network slices, then different parts of data are transmitted by utilizing the plurality of slices according to a negotiated data splitting mode, and as long as data leakage does not occur to all the accessed network slices, safe transmission of the transmitted data can be ensured, thereby improving the service experience of users.
The plurality of data segments are transmitted through different network slices respectively, so that the transmission speed can be increased by selecting parallel transmission of the plurality of network slices, specifically, parallel data transmission of the data segments through the corresponding network slices can be performed according to slice information of a receiving party, and of course, transmission modes such as sequential transmission of the plurality of slices can be selected, which is not limited herein.
In addition, the data segment can be directly transmitted through the network slice after being packaged, in order to further enhance the confidentiality of data transmission, the data segment can also be encrypted and then packaged for transmission, and specifically, before the data segment is transmitted to a receiving party through a corresponding network slice according to slice information of the receiving party, the data segment is encrypted according to a predetermined encryption rule to generate an encrypted data segment; then, according to the slice information of the receiving party, the data transmission of the data segment through the corresponding network slice is as follows: and carrying out data transmission on the encrypted data segment through the corresponding network slice according to the slice information of the receiver. Through data segment encryption processing, even if data in a certain slice is illegally intercepted and acquired, only encrypted partial data ciphertext is obtained, information cannot be directly acquired, and the safety of data transmission is further enhanced. When data encryption transmission is carried out, the data encryption and decryption mode needs to inform a data receiving party, so that the receiving party carries out decryption and recombination after receiving each data segment to obtain transmission data.
And step s124, the receiving party receives the data segment.
And step s125, the receiver performs data restoration on the data segment according to the sender slice information and the data splitting transmission rule to obtain transmission data.
After receiving data through a plurality of slices, a receiver needs to reversely combine and restore the data into original data according to a data splitting mode, so that transmission data is obtained, and data transmission is completed.
Based on the above description, in the 5G data transmission method provided in this embodiment, two communication parties are simultaneously accessed to multiple network slices, data to be transmitted is split into multiple parts according to a predetermined data splitting transmission rule, and then data transmission is performed through the corresponding network slices, each network slice has completely independent resources and management, the slices are isolated from each other, data in one slice is stolen without affecting secure and confidential transmission of data in other slices, and secure transmission of transmission data can be ensured as long as data leakage does not occur to all the accessed network slices, so that the security of the data transmission process is greatly enhanced, the data security degree is improved, and the service experience of a user is improved.
Example two:
in order to deepen the understanding of the 5G data transmission method provided by the present invention, the present embodiment is described with a security and privacy data transmission flow of some application performed by the terminal 1 and the terminal 2. The method mainly comprises the following steps:
1) terminal 1 accesses slice 1 and obtains an IP address (IP 11).
2) The terminal 2 is accessed into the slice 1; an IP address is obtained (IP 21).
3) The terminal 1 and the terminal 2 negotiate with each other through the initially accessed slice 1 to determine a security level required for subsequent transmission, for example, the negotiated security level is a secret level (where the security level includes: secret, secret-secret, and secret-absolute).
4) The terminal 1 and the terminal 2 search and determine the slice 2 to be accessed again to split and transmit in the respective pre-configured tables according to the negotiated secret level security level, and the determined splitting mode is that the odd byte combination of the original data packet is transmitted by the slice 1, and the even byte combination of the original data packet is transmitted by the slice 2.
5) Terminal 1 accesses slice 2 and obtains an IP address (IP 12).
6) Terminal 2 accesses slice 2. An IP address is obtained (IP 22).
7) Terminal 1 and terminal 2 exchange the IP address and port number in slice 2 between both sides in slice 1, that is, terminal 1 informs terminal 2 of IP12 and its port number used for slice 2 transmission, and terminal 2 informs terminal 1 of IP22 and its port number used for slice 2 transmission.
8) The terminal 1 and the terminal 2 transmit different parts of the data by using the slice 1 and the slice 2 simultaneously according to the determined data splitting mode. Specifically, the terminal 1 transmits a combination of odd bytes in the original packet to be transmitted using the slice 1, and transmits a combination of even bytes in the original packet using the slice 2.
9) After receiving the data of the two slices, the terminal 2 needs to perform combined restoration of the data packets according to the principle of split transmission in 8).
Similarly, the data packet sent by terminal 2 to terminal 1 is processed as described above.
