In a 5G network, a large number of access nodes are generated, and the requirements of processed services are diversified, which cannot be met by a traditional data transmission mode. The invention performs decoupling and common extraction on the functions of related data transmission services aiming at the related protocol stack of the access network to obtain the independent micro service units. Each micro-service unit corresponds to a function for data transmission. Of course, the micro-service units obtained by the method of the present invention are not unique, and if the rest of the micro-service units are divided, the method also falls into the protection scope of the present invention.
Example one
As shown in fig. 1, the method for transmitting data in a 5G access network based on a micro service unit according to this embodiment includes:
101. according to the functional characteristics of the access network related protocol stack, decoupling and common extraction are carried out on functions used for data transmission to obtain a plurality of micro service units;
in this embodiment, each of the obtained micro service units is the above-mentioned 15 micro service units.
102. After the terminal service is obtained, in each micro-service unit, the micro-service units matched with the terminal service requirements are called and connected to form a micro-service arrangement module so as to complete the terminal service.
When the terminal requests the service A, the 5G access network calls n (n is more than or equal to 1) micro service units matched with the requirement of the service A from the divided 15 micro service units to form a micro service arrangement module corresponding to the service A. The micro-service arrangement module corresponding to the service A integrates the functions of n micro-service units, and the functions are all used for data transmission, so that the service A can be completed.
In this embodiment, the problem of radio access network closure and hardening in the prior art is solved, and each micro service unit is divided according to an access network related protocol stack, and each micro service unit corresponds to a function for data transmission. When the 5G access network needs to process a certain terminal service, the micro service units with matched functions are called in each micro service unit to form a micro service arrangement module so as to complete the terminal service. The method provided by the embodiment can flexibly complete the terminal service and can meet the requirement of diversity of the service.
Example two
When a terminal moves from the coverage of one cell to the coverage of another, a handover occurs, each radio bearer having a seamless handover or a lossless handover adapted thereto, depending on the QoS requirements of the current service. For some error-sensitive and delay-tolerant non-real-time applications, the access network may utilize an ARQ retransmission mechanism of the RLC layer in the acknowledged data transmission mode to ensure reliability in the data transmission process, and may use lossless handover when the UE performs handover to meet QoS requirements of the non-real-time applications.
As shown in fig. 2, the method for transmitting data in a 5G access network based on a micro service unit according to this embodiment includes:
201. according to the functional characteristics of the access network related protocol stack, decoupling and common extraction are carried out on the functions used for data transmission, and a plurality of micro service units are obtained.
In this embodiment, the above 15 micro service units are obtained.
202. Monitoring the micro service unit called after the terminal service is completed each time, and finding out a high-frequency micro service unit; specifically, the method comprises the following steps:
periodically monitoring micro service units called after the service of each terminal is completed, and forming a history record;
and finding out the high-frequency micro service units in the current monitoring period in the historical record.
In this embodiment, a Kafka message middleware may be disposed in the 5G access network to store a history log of the service request, which is used to record the invoked micro service unit corresponding to the completed service. The 5G access network utilizes the dictionary tree to count the called times of each micro service unit in the historical record log within 24 hours at 0 point every day by setting a monitoring module.
In this embodiment, since the call of the monitoring microservice unit of the 5G access network is continuously performed, the total monitoring duration is periodically divided into monitoring periods. In a monitoring period, the micro service units which are called more than the preset number are high-frequency micro service units, so that the high-frequency micro service units in different monitoring periods can be different micro service units. For example, in the first monitoring period, the route diversity unit is a high-frequency micro-service unit, and in the second monitoring period, the number of times that the route diversity unit is called does not exceed the preset number.
In the current monitoring period, the high-frequency micro service unit comprises: the device comprises a bearer establishing unit, an encryption protection unit, a data processing unit, a data transmission unit, an HARQ unit, a reordering unit, a data recovery unit, a decryption verification unit, a re-blocking unit and an ARQ unit.
203. Generating service fragments according to the high-frequency micro service units; the high-frequency micro-service unit is a micro-service unit with calling frequency exceeding preset frequency; specifically, the method comprises the following steps:
and storing the addresses of the high-frequency micro-service units in the current monitoring period into a hash table to generate corresponding service fragments.
And storing the addresses of the 10 high-frequency micro service units in a hash table to generate service fragments corresponding to the terminal service.
In this embodiment, since the high frequency microservice units in each monitoring period may be different, the service fragmentation in each monitoring period may also be different. Therefore, both the terminal traffic and the corresponding invoked service fragments belong to the same monitoring period.
204. Calling a corresponding high-frequency micro-service unit according to the service fragment corresponding to the current terminal service; specifically, the method comprises the following steps:
finding out the address of each corresponding high-frequency micro-service unit in a hash table of a service fragment corresponding to the current terminal service;
and calling the high-frequency micro-service units according to the addresses of the high-frequency micro-service units.
In this embodiment, the addresses of the 3 high frequency micro service units are first found according to the mapping of the key code values in the service fragments to the corresponding positions in the table.
205. In each micro service unit, calling other micro service units which are matched with the current terminal service requirement and are not contained in the current service fragment;
in this embodiment, the 5G access network first finds, according to the requirements of the response data transmission service request on delay tolerance and low packet loss rate, that the matched micro service unit includes: and switching the retransmission unit.
Thus, other microservice units include: and switching the retransmission unit.
206. And connecting the other micro service units and the corresponding high-frequency micro service units in series and/or in parallel to form a micro service arrangement module of the current terminal service.
And combining 10 high-frequency micro-service units found by the service fragments and 1 other micro-service unit into a micro-service arranging module.
207. And the current terminal service is completed by utilizing the function for data transmission contained in the micro-service arrangement module.
And utilizing the functions related to data transmission of 10 high-frequency micro service units and 1 other micro service unit contained in the micro service arrangement module formed by connecting and combining to complete the reconstruction of the data transmission function of the access network required by the current service. And the connection mode of the 11 micro service units comprises serial connection and/or parallel connection.
Compared with the first embodiment, the embodiment first uses the service fragments to find the high-frequency micro service unit, and then supplements other service units according to the service requirement, thereby saving the time for completing the terminal service. The method described in this embodiment enables the 5G access network to meet the forwarding requirement of diversified service high-efficiency data.
EXAMPLE III
As shown in fig. 3, in this embodiment, in a URLLC application scenario, a data transmission method for a 5G access network based on a micro service unit is provided. In order to better concentrate radio resources, in this embodiment, a 5G and lte dual-connectivity architecture is selected to support data diversity replication of the PDCP layer, where a 5G gbb is used as a macro station and an lte eNB is used as a small station. When the new service request is converted to the URLLC application scenario, the 5G access network finds the microservice orchestration module 300 on the basis of the service fragments according to the low-latency high-reliability service requirement of the URLLC scenario. The micro-service orchestration module 300 includes the following micro-service units in the macro station:
a bearer establishing unit 301, which has a main function of establishing a radio bearer according to the RRC reconfiguration message after completing security activation;
an encryption protection unit 302, whose main functions are to number the data packets and ensure the security of data transmission;
a data processing unit 303, whose main function is to change the size of the transmitted data packets to adapt their size to the actual transmission by the radio interface;
a data transmission unit 304, whose main function is to provide a transmission channel for data or signals to be transmitted;
an HARQ unit 305 whose main function is to improve the reliability of the data transmission process by adding redundant information error correction and retransmission;
a reordering unit 306, whose main function is to reorder the packets that are not received in order and discard the packets that are received repeatedly or overtime;
a data recovery unit 307, whose main function is to recover the data packets in blocks or in series into data packets of the original size at the receiving end;
a decryption verification unit 308, whose main functions are to decrypt the control plane data and the user plane data and to verify the integrity of the control plane data;
a data copying unit 309 whose main function is to copy PDCP layer packets;
the route diversity unit 310 is responsible for data routing of the PDCP layer when separating bearers.
Finding other micro service units needing to be expanded by the 5G access network through the current service requirement comprises the following steps: a data replication unit 309 and a route diversity unit 310.
In the macro station, the bearer establishing unit 301, the encryption protection unit 302, the data processing unit 303, the data transmission unit 304, the hybrid automatic repeat request unit 305, the reordering unit 306, the data recovery unit 307, and the decryption verification unit 308 are high frequency micro service units and are connected in sequence.
The data copying unit 309 is connected 310 to the encryption protection unit 302 and the route diversity unit, respectively.
Similarly, the 5G access network finds the micro-service orchestration module 500 on the basis of service fragmentation. The micro-service orchestration module 500 comprises the following micro-service units in the small station: a bearer establishing unit 501, an encryption protection unit 502, a data processing unit 503, a data transmission unit 504, an HARQ unit 505, a reordering unit 506, a data recovery unit 507, a decryption verification unit 508, a data replication unit 509, and a route diversity unit 510.
The bearer establishing unit 501, the encryption protection unit 502, the data processing unit 503, the data transmission unit 504, the hybrid automatic repeat request unit 505, the reordering unit 506, the data recovery unit 507, and the decryption verification unit 508 are connected in sequence.
The data processing unit 503 of the small station is connected to the route diversity unit 310 of the macro station.
The business process of combining these micro-service units is as follows:
at a sending end, a 5G access network firstly calls an encryption protection unit 302 after establishing a radio bearer by using a bearer establishing unit 301 at a macro station according to service requirements, adds a serial number to a data packet to be sent, and completes encryption of control plane data and user plane data and integrity protection of the control plane data; then, the route diversity unit 310 separates the data packet to be sent copied by the data copying unit 309 and carries the data packet to be sent to the RLC layer of the small station; then, the macro station and the small station are respectively blocked or connected in series into data packets with proper size by using the data processing units 303 and 503 according to the size of the actual wireless interface; then, the mapping between the logical channels and the corresponding transmission channels is completed through the data transmission units 304 and 504, the data packet is transmitted to the PHY by using a multiplexing technique, and is further converted into a radio signal that can be received by the UE after baseband processing, and the radio signal is transmitted to the UE through radio frequency.
At a receiving end, the 5G access network completes a baseband processing process through the data transmission units 304 and 504, restores the radio signal received by the UE to a transmission block, and sends the transmission block to an upper layer by a PHY by using a demultiplexing and mapping technology; then, the HARQ units 305 and 505 are called to correct errors and retransmit erroneous data packets; then, the received data packets are renumbered and rearranged in sequence by the reordering units 306 and 506, and repeatedly received packets or overtime data packets are discarded; finally, the data recovery units 307 and 507 are used to reconstruct the effective segment, and the service data packet required by the UE is obtained after the processing by the decryption verification units 308 and 508.
As can be seen from the above-mentioned implementation of low-delay and high-reliability services in URLLC scenarios, in this embodiment, a micro-service orchestration module 300 is first established in a macro station, and a micro-service orchestration module 500 is established in a small station. And then the data transmission functions of the two micro-service arranging modules are utilized to realize the service requirements together.
In order to ensure that the current service is not interrupted, the 5G access network will replace the data transmission unit of the small station with the micro-service unit having the same function in the macro station. The above alternative method may be: registering each micro-service unit in a service registration center; the service registration center generates a corresponding node (storing relevant information of the service) according to each micro-service unit service, and the node has a unique id and an IP address in the service registration center; when the data transmission unit 504 of the small station fails and service replacement on the data transmission unit 304 of the macro station is needed, the IP address of the data transmission unit 504 of the small station is modified into the IP address of the data transmission unit 304 of the macro station, and the corresponding id of the data transmission unit 304 of the macro station is modified into the id of the data transmission unit 504 of the small station.
Further, if the micro service units required by the subsequent services of the UE are not deployed in the small station, corresponding micro service units can be found in the macro station to complete the same function, thereby improving flexibility and openness of service deployment of the access network.
