Background

With the continuous development and evolution of 5G NR (5 th generation mobile communication system) technology, the user plane protocol stack has been widely used. The architecture of the user plane protocol stack comprises: a data adaptation protocol (Service Data Adaptation Protocol, SDAP) for mapping between network QoS flows and DRBs, a packet data convergence protocol (Packet Data Convergence Protocol, PDCP) for header compression of IP packets, encryption and decryption of data, timing dropping, retransmission and reordering at re-establishment, a radio link control Layer (Radio Link Control, RLC) for segmentation, re-segmentation, reassembly and automatic request retransmission of protocol data units (Protocol Data Unit, PDUs) of PDCP, a media access control Layer (Medium Access Control, MAC) for mapping between logical channels and transport channels, multiplexing and de-multiplexing of data, hybrid automatic request retransmission (Hybrid Automatic Repeat Request, HARQ) and air interface scheduling, and a Physical Layer (PLY) for underlying coding and decoding.

In data transmission through the user plane protocol stack, there are typically three modes: an Acknowledged Mode (AM), a unacknowledged Mode (Unacknowledged Mode, UM), and a Transparent Mode (TM), wherein the AM Mode supports data retransmission, requires a transmitting end to transmit higher layer data after adding necessary control protocol overhead, and ensures reliable delivery to a peer entity. When data is transferred from the PDCP layer to the RLC layer, the data output by the PDCP layer is usually stored in the memory space 1, then RLC packetizing is applied to the data output by the PDCP layer in the memory space 2, the RLC packetizing process includes copying the data from the memory space 1 to the memory space 2, deleting the data in the memory space 1 after the packetizing is completed, releasing the memory space 1, and participating in the packetizing of the DMAC layer through the data in the memory space 2 until RLC acknowledgement information of the UE is received, deleting the data in the memory space 2, and releasing the memory space 2.

For the purposes of making the objects, technical solutions and advantages of the embodiments of the present application more clear, the technical solutions of the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is apparent that the described embodiments are some embodiments of the present application, but not all embodiments.

Fig. 2 is a flow chart of a method for buffering service data in a 5G base station according to an embodiment. The embodiment relates to a specific process of how to obtain DMAC packet data by packetizing a plurality of first data through the RLC layer, and transmitting the DMAC packet data. As shown in fig. 2, the method comprises the steps of:

s101, storing a plurality of first data in a first memory space corresponding to a radio link control layer (RLC), wherein the first data are obtained after the communication equipment processes the first data through a Packet Data Convergence Protocol (PDCP) layer.

The first data is output data PDUs of the packet data convergence protocol PDCP layer, that is, input data SDUs of the RLC layer of the radio link control layer, which may be obtained by the communication device after processing the packet data convergence protocol PDCP layer, and when the first data is sent to the RLC layer, the first data is stored in a first memory space corresponding to the RLC. The communication device may store a plurality of first data in the first memory space in an order in which the respective first data are transmitted to the RLC layer. The communication device may be a base station or a user equipment, which is not limited in this embodiment of the present application. Typically, the PDCP layer is disposed in a Convergence Unit (CU), which mainly includes a non-real-time radio higher layer protocol stack function, while also supporting sinking of part of the core network functions and deployment of edge application services. The RLC layer is usually disposed in a Distributed Unit (DU), and the DU mainly handles the physical layer functions and layer functions required by real-time performance, so that, considering saving transmission resources between the remote radio Unit (Radio Remote Unit, RRU) and the DU, part of the functions of the physical layer can also be implemented by moving to the RRU, and the passive antenna is combined into an active antenna system (Active Antenna Unit, AAU). The CU and the DU are connected through an F1U interface. When storing the plurality of first data in the first memory space corresponding to the radio link control layer RLC, the plurality of first data is generally received through the F1U interface, and then stored in the first memory space corresponding to the radio link control layer RLC.

S102, when receiving the media access control CMAC schedule, packing a plurality of first data according to a data format of the media access control data DMAC packet by an RLC layer to obtain DMAC packet data.

The data format of the DMAC packet of the medium access control data may include a data header and a data body. In the communication protocol of 5G, since the RLC layer only segments data and does not involve concatenation of data, there is a simple and clear correspondence between SDUs of the RLC layer, PDUs and PDUs of the MAC layer, so that the RLC layer may, after receiving first data sent by the PDCP layer, perform, when receiving the CMAC schedule, packetizing, by the RLC layer, a plurality of first data according to a DMAC packetizing data format, to directly obtain PDUs of the MAC layer, that is, DMAC packetizing data.

S103, transmitting the DMAC packet data.

Specifically, after obtaining the DMAC packet data, that is, obtaining the output data PDUs of the MCA layer, the communication device may continue to transmit the DMAC packet data between the protocol layers. For example, DMAC group packet data of the MCA Layer may be transferred to a Physical Layer (PLY) for bottom Layer encoding and decoding.

According to the method for caching and processing service data by the 5G base station, the communication equipment stores a plurality of first data in the first memory space corresponding to the radio link control layer RLC, wherein the first data is obtained after the communication equipment processes the data through the packet data convergence protocol PDCP layer, and when the media access control CMAC scheduling is received, the data of the DMAC packet is obtained by packing the plurality of first data through the RLC layer according to the data format of the media access control data DMAC packet, and then the DMAC packet data is transmitted, so that the situation that the first data stored in the first memory space is packed through the RLC layer and stored in the other memory space in the traditional method is avoided, and then the first data stored in the other memory space is transmitted to the MAC layer, and then the DMAC packet is obtained.

Fig. 3 is a flow chart of a method for buffering service data in a 5G base station according to another embodiment, which relates to a specific process of packetizing a plurality of first data according to a data format of a DMAC packet by an RLC layer, as shown in fig. 3, S102 "packetizing a plurality of first data according to a data format of a DMAC packet by an RLC layer" one possible implementation method includes:

s201, through the RLC layer, the RLC serial number corresponding to each first data is obtained.

When the plurality of first data are stored in the first memory space corresponding to the RLC layer, the plurality of first data are stored in the first memory space corresponding to the RLC layer one by one, so that each first data can generate the RLC sequence number corresponding to the first data according to the sequence of storing the first data in the first memory space corresponding to the RLC layer. And the RLC layer records the RLC serial numbers corresponding to the first data generated when the first data are stored in the first memory space, and acquires the RLC serial numbers corresponding to the first data.

S202, according to the acquired RLC serial numbers, the plurality of first data are packetized according to the data format of the DMAC packetizing through the RLC layer, and DMAC packetizing data are obtained.

On the basis of the above embodiment, when the RLC sequence number of each first data is obtained, the RLC layer may perform packetizing on each first data according to the DMAC packetizing data format to obtain DMAC packetizing data. Alternatively, the DMAC packetizing data may be obtained by packetizing the respective first data by the embodiment shown in fig. 4.

Fig. 4 is a flow chart of a method for buffering service data in a 5G base station according to another embodiment, which relates to a specific process of grouping a plurality of first data according to an acquired RLC sequence number and a data format of DMAC grouping through an RLC layer to obtain DMAC grouping data, as shown in fig. 4, S202 "the method includes, according to the acquired RLC sequence number, grouping a plurality of first data according to the data format of DMAC grouping through the RLC layer to obtain DMAC grouping data", and one possible implementation method includes:

s301, for each first data, generating a data head through the RLC layer according to the RLC serial number corresponding to the first data, and splicing the generated data head and the first data to obtain pre-packet data.

For each first data, the RLC sequence number corresponding to the first data may be generated by the RLC layer to generate a data header, and the generated data header and the first data are spliced to obtain pre-packet data corresponding to the first data. Generating data heads of the plurality of first data according to the RLC serial numbers corresponding to the plurality of first data, and splicing the data heads of the first data with the corresponding first data to obtain a plurality of pre-packed data. It should be noted that the pre-packet data may be stored in the first memory space.

S302, splicing the obtained data of the plurality of pre-packets according to the data format of the DMAC packets through the RLC layer to obtain the data of the DMAC packets.

On the basis of the above embodiment, after a plurality of pre-packet data are obtained, a data header of a DMAC may be spliced to each pre-packet data according to a data format of a DMAC packet through the RLC layer, so as to obtain a plurality of spliced pre-packet data, and the plurality of spliced pre-packet data are sequentially connected to obtain the DMAC packet data.

According to the method for caching and processing the service data by the 5G base station, the communication equipment acquires the RLC serial numbers corresponding to each first data through the RLC layer, and packs the plurality of first data through the RLC layer according to the acquired RLC serial numbers and the data format of the DMAC pack to obtain the DMAC pack data.

On the basis of the above embodiment, before storing the plurality of first data in the first memory space corresponding to the radio link control layer RLC, the communication device may further obtain the first data by determining whether the ROHC needs to be compressed by using the robust header of the second data obtained by processing the second data by using the service data adaptation protocol SDAP layer, which will be described in detail below with reference to fig. 5 and 6.

Fig. 5 is a flow chart of a method for buffering service data in a 5G base station according to another embodiment, where the embodiment relates to a specific process of how to obtain first data, and as shown in fig. 5, the method further includes:

s401, storing second data into a second memory space corresponding to the PDCP layer, wherein the second data is obtained after the communication equipment processes the second data through a service data adaptation protocol SDAP layer.

The SDAP layer is the upper layer of the PDCP layer, and the output data of the SDAP layer obtained after the SDAP layer is processed is the second data. The PDCP layer stores second data in a second memory space corresponding to the PDCP layer when receiving output data of the SDAP layer of its corresponding upper layer, that is, the second data.

S402, determining whether robust header compression ROHC is needed for the second data or not according to the data identification in the second data by the PDCP layer.

Wherein the data identification in the second data may be used to indicate whether the second data requires robust header compression ROHC. When the data identifier in the second data indicates that the second data is signaling data, ROHC needs to be performed on the second data, and when the data identifier in the second data indicates that the second data is traffic data, ROHC does not need to be performed on the second data. In general, during data transmission, the proportion of traffic class data in the total data amount is far higher than the proportion of signaling class data in the total data amount. That is, a large amount of data is not required for robust header compression ROHC at the PDCP layer.

S403, when ROHC is not needed to be carried out on the second data, encryption processing is carried out on the second data in the second memory space, and the first data are obtained.

The PDCP layer mainly realizes header compression of data, encryption and decryption of the data, timing discarding, retransmission and reordering processing during reconstruction. When ROHC is not needed, encryption processing is needed to be performed on the second data in the second memory space, so as to obtain the first data. Optionally, the hardware accelerator QAT technology is adopted to encrypt the second data in the second memory space, so as to obtain the first data.

The hardware accelerator QAT technology is a hardware acceleration technology which is proposed for network security and data storage, and a memory space exists in the hardware accelerator for storing the encrypted data, so that the PDCP layer does not need to copy the data in the PDCP layer in the encryption process. In the present application, the second data is encrypted by using the memory space inside the hardware accelerator, so as to obtain the first data, that is, the output data of the PDCP layer.

When ROHC is required for the second data, the first data may alternatively be obtained by the embodiment shown in fig. 6. Fig. 6 is a flow chart of a method for buffering service data in a 5G base station according to another embodiment, where the embodiment relates to a specific process of how to obtain first data, and as shown in fig. 6, the method further includes:

s501, when ROHC needs to be conducted on the second data, a third memory space is applied.

S502, ROHC is conducted on second data in the second memory space, compressed second data are obtained, and the compressed second data are stored in the third memory space.

When ROHC is required to be performed on the second data, the PDCP layer may apply for a third memory space corresponding to the PDCP layer. The third memory space is used for storing the second data after the robust header compression. And performing ROHC on the second data in the second memory space through the PDCP layer to obtain compressed second data, and storing the compressed second data in the third memory space.

S503, encrypting the compressed second data in the third memory space to obtain first data.

Optionally, when acknowledgement information sent by the UE is received, deleting the second data stored in the second memory space, where the acknowledgement information is used to indicate that the UE receives data sent by the base station.

When ROHC is required to be performed on the second data, the compressed second data in the third storage space is encrypted to obtain the first data. And further, storing the first data in a first memory space corresponding to the radio link control layer RLC, and when receiving the media access control CMAC scheduling, packing the plurality of first data according to a data format of the media access control data DMAC packet by the RLC layer to obtain the DMAC packet data, and further transmitting the DMAC packet data. At this time, if the UE receives the data corresponding to the DMAC packet data, the PDCP layer may send other information for indicating that the UE received the data, and delete the second data in the second memory space after receiving the acknowledgement information, so that the second memory space is released.

According to the method for caching and processing the service data by the 5G base station, the second data are stored in the second memory space corresponding to the PDCP layer, wherein the second data are obtained after the communication equipment processes the second data through the SDAP layer, the PDCP layer determines whether the robust header compression ROHC needs to be performed on the second data according to the data identification in the second data, and when the ROHC does not need to be performed on the second data, the second data in the second memory space are encrypted, so that the first data are obtained. The first data obtained through the PDCP layer does not need to carry out robust header compression ROHC once, encryption processing is carried out again, and when second data which does not need to carry out ROHC is encrypted, the encrypted data does not need to be stored in an external memory space, so that data copying during data transmission between protocol layers is further reduced, namely data transmission quantity between protocol layers is reduced, and data transmission efficiency is improved.

It should be understood that, although the steps in the flowcharts of fig. 2-6 are shown in order as indicated by the arrows, these steps are not necessarily performed in order as indicated by the arrows. The steps are not strictly limited to the order of execution unless explicitly recited herein, and the steps may be executed in other orders.
