In the embodiment of the application, aiming at the realization method of the network layer, the link layer and the physical layer of the air interface in the 5G mobile communication network, the realization method of the invention can greatly simplify the realization of the bottom communication protocol of the 5G base station and the mobile phone and improve the processing performance.
In order to guarantee the compatibility and interoperability of base stations and handsets produced by multiple vendors, the 3GPP international standardization organization defines detailed and complex protocol layers for the 5G air interface, including NGAP & GTP, RRC & SDAP, PDCP, RLC, MAC, PHY, in order from the mobile core network to the air interface. Such a plurality of protocol layers are defined, on the one hand, because of the need for reliable and efficient transmission of service data, and on the other hand, the design of the previous generations of mobile communication protocol stacks has been inherited.
Although the protocol layers differ in implementation function, in reality some functions are similar, such as retransmission mechanisms all exist in PDCP, RLC, MAC, PHY, with a focus on differences. Also, for example, the communication resource scheduling function, there is a design in almost every protocol layer. The advantage of this design is that it is theoretically easy to understand, and the well-defined boundaries between protocol layers are beneficial for problem localization. The method has the defects of complex protocol stack, high realization cost, repeated functions and low overall communication efficiency, and takes research and development of public mobile network base station equipment as an example, under the layered realization scene of a plurality of protocol layers, the research and development and the test of software are required to be carried out for each layer, and huge research and development teams and repeated tests are required. Based on the above situation, the present application provides a message processing method and device applied to 5G mobile communication.
In an embodiment of the present application, a first flow diagram of a message processing method applied to 5G mobile communication is provided, as shown in fig. 1, the method includes steps S101-S103.
S101, acquiring an original protocol layer contained in a control channel, wherein the control channel is used for transmitting downlink control information, and the downlink control information comprises an NG protocol data packet.
In the embodiment of the present application, four sub-protocol layers at the data link layer are a medium access control layer (MAC), a radio link control layer (RLC), a packet data convergence protocol layer (PDCP), and a service data adaptation protocol layer (SDAP), respectively.
S102, merging original protocol layers with the same function in the original protocol layers to obtain a plurality of functional modules.
In this embodiment of the present application, original protocol layers with the same functions in each original protocol layer are combined, the same functions may be that part of the original multiple protocol layers have the same functions, and multiple parts with the same functions are combined to obtain multiple functional modules.
For example, a PDU packet of a user plane needs to be submitted to the next layer for processing through some buffering and message mechanism after completing the processing of each protocol layer according to the conventional layered processing mechanism, which causes multiple processing delays and increases the processing load after multi-layer processing. After adopting the simplified protocol frame mechanism of the invention, a PDU grouping packet can be directly delivered to the PHY physical layer for transmission after finishing the function processing of each protocol layer in one processing process according to the protocol function defined in the prior standard protocol, thereby saving the original multiprocessing and buffering expense.
And S103, sequentially adopting a plurality of functional modules to transmit the downlink control messages according to the sequence so as to transmit the downlink control messages to the wireless air interface module.
In this embodiment of the present application, the plurality of functional modules obtained in step S102 are ordered according to the requirements of the message transmission process, and the downlink control messages are sequentially transmitted to the wireless air interface module.
In a possible implementation manner, as shown in fig. 2, in step S103, a plurality of functional modules are sequentially used to transmit the downlink control message according to a sequence, so as to transmit the downlink control message to the air interface module, which specifically includes steps S1031-S1035.
S1031, the NG protocol data packet is converted into a first data packet adapted to the wireless air interface.
In one possible implementation, as shown in fig. 3, step S1031 converts the NG protocol data packet into a first data packet adapted to the wireless air interface; specifically, steps S1031a-S1031b are included.
S1031a, when the downlink control message is a control plane message, receiving the NG protocol data packet through the control plane interface.
S1031b, completing the control plane interface protocol and carrying out the integrity processing of the NG protocol data packet to obtain a first data packet.
For example, the mobile core network sends a control plane message to be sent to the base station to the control plane processing sub-module through the NG-C interface, where the control plane processing sub-module is a part of the integrity processing module, implements the NG-C interface protocol, and performs integrity processing on the data packet. The control plane information is converted into a physical layer transmission block TB after being processed by a control plane processing module in the resource scheduling module, and then is sent to the PHY physical layer.
In one possible implementation, as shown in fig. 3, step S1031 converts the NG protocol data packet into a first data packet adapted to the wireless air interface; specifically, steps S1031c-S1031d are included.
S1031c, when the downlink control message is a user plane message, receiving the NG protocol data packet through the user plane interface.
S1031d, finishing the user interface protocol and carrying out the integrity processing of the NG protocol data packet to obtain a first data packet.
For example, the mobile core network sends the user plane message to be sent to the base station to the user plane processing sub-module through the NG-U interface, and the user plane processing sub-module is a part of the integrity processing module, implements the NG-U interface protocol, and performs the integrity processing of the data packet. After being processed by a user plane processing module in the resource scheduling module, the user plane message is converted into a physical layer transmission block TB and then sent to the PHY physical layer.
For the uplink message, i.e. the message from the PHY physical layer, the corresponding protocol processing is done in reverse through the path described above.
In one possible implementation, the NG protocol data packet is converted into a first data packet adapted to the wireless air interface, specifically including: and sequentially carrying out segmentation processing, sequence number increasing processing, encryption and decryption processing, sequencing processing, packet header compression processing and protocol packet header increasing processing on the NG protocol data packet to obtain a first data packet.
S1032, the first data packet is subjected to receiving and transmitting control to obtain a second data packet, and a label for identifying the type of the second data packet exists in the second data packet.
In one possible embodiment, as shown in fig. 4. Step S1032, the first data packet is subjected to receiving and transmitting control to obtain a second data packet, which specifically includes steps S1032a-S1032c.
S1032a, receiving the first data packet, and sending a feedback message to the target device, where the target device is the sender of the downlink control message.
S1032b, when the target device receives the feedback message, the first data packet is subjected to sorting and multiplexing to obtain a second data packet.
S1032c, when the target device does not receive the feedback message, resending the feedback message until the target device receives the feedback message.
S1033, distributing physical layer transmission resources for the second data packet according to the label.
S1034, according to the physical layer transmission resource, the transmission processing of the physical layer protocol is carried out on the second data packet.
And S1035, sending the second data packet which completes the transmission processing of the physical layer protocol to the wireless air interface module.
For example, taking a downlink control message as an example, the downlink control message from a mobile core network or a base station internal control state machine firstly enters an integrity processing module to perform processes such as header compression, sequence number adding, dicing, and original protocol packet header adding; then the data is sent to an interaction processing module, namely, the processing such as feedback sending, retransmission, sequencing, multiplexing and the like is carried out; then, the message is sent to a resource scheduling module to carry out resource assignment on the message; and finally, the data is sent to a physical layer for processing a physical layer protocol and is sent to an air interface. In addition, the processing of the uplink control message is the reverse processing of the downlink control message, and the disclosure is not repeated here.
In another embodiment of the present application, taking a downlink user plane message as an example, a user plane message from a mobile core network first enters an integrity processing module, performs header compression, sequence number processing, blocking and sequencing, adding an original protocol packet header, and the like, then sends the message to an interaction processing module, performs processing such as sending, retransmitting, feedback message processing, multiplexing, and the like, and then sends the message to a resource scheduling module, assigns downlink channel resources to the message, and then sends a physical layer to perform transmission processing of an original physical layer protocol, and sends the message to an air interface.
In other message types, similar processing is adopted for other messages of uplink and downlink, the original multi-layer protocol layering processing is converted into the unified realization of the functions of all protocol layers by a single integrity processing module, an interaction processing module and a resource scheduling module, and therefore the realization of a protocol stack is greatly simplified.
The beneficial effects that can be achieved by the embodiment of the method include:
1. and combining the original protocol layers with the same function in the original protocol layers to obtain a plurality of functional modules, thereby simplifying the realization of a bottom communication protocol in the 5G mobile communication process and improving the overall communication efficiency of the server.
2. And transmitting the downlink control message by adopting a plurality of functional modules in sequence so as to transmit the downlink control message to the air interface module.
