In actual applications, the SDAP module in the base station is equipped with a reflection control unit. , The reflection control unit is used to execute the data transmission method provided in this application.

The embodiments of the present application provide a message transmission method, device, computer equipment, and storage medium. The technical solutions of the present application and how the technical solutions of the present application solve the above technical problems will be described in detail through the embodiments and the accompanying drawings. . The following specific embodiments can be combined with each other, and the same or similar concepts or processes may not be repeated in some embodiments. It should be noted that, in a message transmission method provided by the present application, the execution body of FIG. 2 to FIG. 4 is a reflection control unit, where the execution body may also be a base station, and the reflection control unit may be implemented through software, hardware, or The combination of software and hardware is implemented as part or all of the base station.

In one embodiment, FIG. 2 provides a message transmission method. This embodiment relates to the reflection control unit, after receiving the first message sent by the core network device, according to the IP carried in the first message. (Internet Protocol, Internet Protocol address) address, the specific process of adjusting the transmission priority of the message, as shown in Figure 2, the method includes:

S101. Receive a first message sent by a core network device; the first message carries the first terminal-side IP address and first QoS information.

In this embodiment, the core network equipment refers to the equipment on the 5G core network side. For example, the 5G core network equipment includes access and mobility management function (AMF) and user plane function (User Plane Function). , UPF) equipment. Among them, the first message represents the message sent by the core network device to the SDAP module in the 5G access network. The first message here is only used for the message received by the SDAP module in the 5G access network (in the base station) in the following embodiments. The second message sent by the PDCP module is distinguished. It does not limit the message sequence and message sequence number. It should be noted that all the first and second functions in the embodiments of this application are used to distinguish, for example, the first The terminal-side IP address, the second terminal-side IP address and the first QoS information below, and the second QoS information below are just for distinguishing. In addition, the first and second packets in this embodiment are In some cases, it can refer to the same message or different messages. Correspondingly, the situation of the terminal-side IP address and QoS information is also the same, which will not be repeated in this embodiment.

Specifically, in practical applications, the reflection control unit in the SDAP module of the base station receives the first message sent by the core network device, where the first message may be a GPRS Tunneling Protocol (GTP) message , The first message carries the first terminal-side IP address and the first QoS information, where the QoS information includes the flow classification, traffic monitoring, traffic shaping, interface speed limit, congestion management, and congestion of the first message Related information to be avoided, such as the SDAP entity and radio bearer (RB) of the message, and the priority of each RB can be obtained from the first QoS information, which is not limited in this embodiment.

S102: If the IP address on the first terminal side is a pre-appointed IP address, determine whether the current RB priority of the first packet is the highest priority according to the first QoS information.

Among them, the embodiments of this application are aimed at improving the transmission quality of a specific IP service flow. Therefore, after receiving the first packet, it is necessary to first determine whether the first packet is a specific IP service flow, that is, to determine the first packet. Whether the first terminal-side IP address carried in the text is a pre-appointed IP address, the reflection control unit will control its transmission priority only if the first message is a pre-appointed IP address.

Specifically, based on the first message received in S101, if the first terminal-side IP address in the first message is a pre-appointed IP address, the reflection control unit reflects the first QoS information carried in the first message Find the current RB and determine whether the priority of the current RB is the highest priority. For example, if the priority level corresponding to each RB is stored in the first QoS information, the reflection control unit can directly determine whether the priority of the RB is The highest priority; if the priority of each RB in the first QoS information is stored in order, the reflection control unit judges whether the priority of the current RB is the highest priority according to the order of each RB, which is not specifically limited in this embodiment . After the judgment result is obtained, if the judgment result is that the priority of the current RB is the highest priority, step S103 is executed, and if the judgment result is that the priority of the current RB is not the highest priority, step S104 is executed.

It should be noted that before the priority of the current RB is not the highest priority, the reflection control unit also needs to determine whether the first packet currently has multiple RBs. If there is only one RB, no subsequent steps are required, and the first packet is directly reported. The current SDAP entity of the message only needs to send the first processing instruction. If the first message has multiple RBs, it is judged whether the priority of the current RB is the highest priority.

S103: If the priority of the current RB is the highest priority, send a first processing instruction to the current SDAP entity of the first message, where the first processing instruction is used to instruct the first message to be encapsulated and sent to the PDCP module.

This step is the case where the above judgment result is that the priority of the current RB is the highest priority. In this case, the current SDAP entity of the first packet of the reflection control unit sends the first processing instruction, where the first processing instruction is used to instruct the After the first message is encapsulated, it is sent to the PDCP module. Wherein, the current SDAP entity of the first message is obtained by the reflection control unit from the first QoS information. For example, after receiving the first processing instruction, the current SDAP entity encapsulates the first packet to encapsulate SDAP header information, and sends the encapsulated first packet to the PDCP module in a SDAP PDU session.

S104: If the priority of the current RB is not the highest priority, select a new SDAP entity according to the first QoS information, and send a first processing instruction to the new SDAP entity; the new SDAP entity represents the SDAP entity corresponding to the RB with the highest priority .

In this step, the result of the above judgment is that the priority of the current RB is not the highest priority. In this case, the reflection control unit needs to reselect a new SDAP entity from the first QoS information carried in the first packet, where the selected new SDAP entity The SDAP entity represents the SDAP entity corresponding to the RB with the highest priority, which is equivalent to controlling the first packet to be transmitted with the highest priority when the first packet is not currently transmitted with the highest priority. Specifically, after the reflection control unit selects a new SDAP entity according to the first QoS information, it sends a first processing instruction to the new SDAP entity, and then the new SDAP entity receives the first processing instruction and sends the first processing instruction to the first packet. The encapsulation process is to encapsulate the SDAP header information, and the encapsulated first message is sent to the PDCP module in an SDAP PDU session.

In the message transmission method provided in this embodiment, when the IP address of the message is a pre-appointed IP address, the reflection control unit determines that the current RB priority of the message is the highest priority, and controls the current message The SDAP entity encapsulates and processes the message and sends the message. In the case that the priority of the current RB of the message is not the highest priority, re-determine the new SDAP entity according to the RB with the highest priority, and control the new entity encapsulation process Send the message, in this method, when the received message is an agreed IP message, no matter what the situation, it can be guaranteed that the message is transmitted by the RB with the highest priority, that is, for the IP flow of the agreed service business In wireless transmission, the priority of the RB bearer is raised to the highest priority, which greatly improves the transmission quality of a specific IP service flow.

When the SDAP header information is encapsulated in the first packet according to the first processing instruction, the RQI (Reflective QoS Indication) field in the SDAP header has different values according to different SDAP entities. An embodiment is provided for this In one embodiment, if the first processing instruction is sent to the current SDAP entity of the first packet, the RQI field in the SDAP header information of the first packet after encapsulation processing is the first value; if the first processing The instruction is sent to the new SDAP entity, and the RQI field in the SDAP header information of the first packet after the encapsulation process is the second value; where the first value and the second value are different values.

Among them, the value of the RQI field in the SDAP header is different after different SDAP entities perform the encapsulation process. For example, if the current SDAP entity encapsulates the SDAP header information for the first packet, the RQI field is set to 0, and if the new one is selected If the SDAP entity encapsulates the SDAP header information for the first packet, the RQI field is set to 1, so that after the downstream protocol receives the first packet, it can distinguish whether the SDAP entity is replaced according to the value of the RQI.

In the foregoing embodiment, the prerequisite for the reflection control unit to determine whether the current RB priority of the first packet is the highest priority based on the first QoS information is to determine that the first terminal-side IP address carried in the received first packet belongs to A pre-appointed IP address, but for the case where the first terminal-side IP address carried in the first message does not belong to the pre-appointed IP address, this application also provides an embodiment. In one embodiment, the method Including: if the IP address of the first terminal side is not a pre-appointed IP address, sending the first processing instruction to the current SDAP entity of the first message. In this embodiment, when the reflection control unit determines that the first terminal-side IP address carried in the first message does not belong to the pre-appointed IP address, that is, the first message is not a pre-appointed message, indicating that the reflection control unit does not To control its bearer priority, the reflection control unit can directly send the first processing instruction to the current SDAP entity of the first message, and let the current SDAP entity to encapsulate and process the first message, and then send the processed first message to the current SDAP entity. A message is sent to the PDCP module. In this way, when the first message received is not an agreed message, there is no need to control its radio bearer priority to be the highest, which saves processing resources.

In step S104 of the foregoing embodiment, when the priority of the current RB is not the highest priority, the reflection control unit needs to select a new SDAP entity according to the first QoS information. For the specific process of the reflection control unit selecting a new SDAP entity, this application provides In one embodiment, as shown in FIG. 3, the "selecting a new SDAP entity according to the first QoS information" in the above step S104 includes:

S201. Obtain the current SDAP entity of the first packet and the RB information of the first packet according to the first QoS information; the RB information of the first packet includes the current RB of the first packet and other RBs except the current RB. , The priority identification of the current RB and other RBs.

In this embodiment, the first packet carries the first QoS information, and the reflection control unit obtains the current SDAP entity of the first packet and the RB information of the first packet from the first QoS information. Among them, one packet It can correspond to multiple RBs, the RB information of the first packet includes the current RB of the first packet, other RBs except the current RB, and the priority identifiers of all RBs, where the priority identifiers of all RBs may be Characters, letters, numbers, or various combinations of identifiers are not limited in this embodiment.

S202: According to the priority identifier, the RB with the highest priority is selected from other RBs.

Since this embodiment is the case where the priority of the current RB is not the highest priority, based on the priority identifier of the RB obtained in step S201, the reflection control unit selects the RB with the highest priority from other RBs, and ensures that the first report The paper bearer has the highest priority.

S203: Determine the SDAP entity of the QoS flow corresponding to the highest priority RB as a new SDAP entity.

Based on the highest priority RB selected in step S202, the reflection control unit determines the SDAP entity corresponding to the highest priority RB as a new SDAP entity. Specifically, the reflection control unit selects the highest priority RB corresponding to any QoS flow , The SDAP entity of any QoS flow is the SDAP entity corresponding to the highest priority RB.

In the message transmission method provided in this embodiment, the reflection control unit selects the RB with the highest priority according to the first QoS information carried in the first message, and determines the SDAP entity corresponding to the RB with the highest priority as the new SDAP The entity, in this way, controls the bearer of the first packet to the highest priority, and controls the SDAP entity corresponding to the highest priority bearer to process the first packet, which improves the transmission quality of the first packet.

After the reflection control unit selects the new SDAP entity according to the first QoS information, it is equivalent to changing the new SDAP to the current SDAP entity that replaced the first packet. In this case, the current SDAP that the first packet is replaced with The entity becomes the original SDAP entity of SDAP. In one embodiment, the method further includes: determining the current SDAP entity of the first message as the original SDAP entity of the first message and storing it.

In this embodiment, the SDAP entity of the first message is replaced with a new SDAP, and its current SDAP entity becomes the original SDAP entity, and the reflection control unit needs to store the original SDAP entity to record the first message The replacement record of the SD AP entity is convenient for subsequent query.

All the above embodiments are based on the flow of packets from the 5G core network device to the SDAP module of the 5G access network and then to the PDCP module of the 5G access network, which belong to the downlink data transmission process. For all the embodiments of the downlink data transmission process, This application provides a complete embodiment. As shown in FIG. 3a, the complete embodiment includes:

S11, receive a message from a core network device, and transfer to S12;

S12, remove the IP/UDP (User Datagram Protocol, User Datagram Protocol)/GTP header overhead of the base station, and switch to S13;

S13: Search for the current SDAP entity and its RB information according to the QoS information carried in the GTP header, and turn to S14;

S14: Judge whether the source IP of the message is the agreed server IP address, if it is, go to S15, otherwise go to S19;

S15, judge whether there are multiple RBs, if it is to go to S16, otherwise go to S19;

S17: Select the highest priority RB corresponding to any QoS flow, determine the SDAP entity of any QoS flow as a new SDAP entity, record the current SDAP entity checked by QoS information, and switch to S18;

S18: Select a new SDAP entity to process the message, that is, encapsulate the SDAP header and set the RQI field to 1, then switch to S10;

S19: The current SDAP entity checked by the QoS information processes the message, that is, encapsulates the SDAP header and S10, and sends the processed message to the corresponding PDCP module in SDAP PDU (Protocol Data Unit).

The message transmission method provided in this embodiment only involves the deep processing optimization inside the base station. The comparison before and after the specific optimization can be seen in Figure 3b. The specific implementation process in this embodiment is the same as the process in all the above embodiments, and it is not here. To repeat, because the main body of execution of all steps in this embodiment is the reflection control unit set in the SDAP module, the reflection control unit is specifically responsible for the IP flow of the agreed service business. In wireless transmission, the priority is raised to the highest priority. RB is carried, and the whole process is executed in the base station, that is, from the perspective of the base station, the customer experience of a specific service is actively guaranteed to the greatest extent.

In addition, there is an uplink data transmission process in practical applications, that is, the flow from the PDCP module of the 5G access network to the SDAP module of the 5G access network and then to the 5G core network equipment. Part of the content is similar to the above-mentioned uplink data transmission process embodiment. The content is repeated, so the repeated content will not be repeated. This application provides an embodiment of the flow direction process. As shown in FIG. 4, the method further includes:

S301: Receive a second message sent by the PDCP module; the second message carries the second terminal side IP address.

In this embodiment, the reflection control unit in the SDAP module of the 5G access network receives the second message sent by the PDCP module. The second message here has been explained in step S101, and it is not about the sequence or serial number of the message. The limitation is only to distinguish it from the first message. Wherein, the second message carries the IP address of the second terminal side.

S302: If the second terminal-side IP address is a pre-appointed IP address, detect whether the second packet has the original SDAP entity of the second packet.

Based on the second message received in step S301, the reflection control unit uses the second terminal-side IP address in the second message as the pre-appointed IP address, detects whether the second message has the original SDAP entity of the second message, This step is executed when the IP address of the second terminal in the second message is the pre-appointed IP address. Therefore, after receiving the second message, the reflection control unit needs to first determine whether the IP address of the second terminal is It is a pre-appointed IP address, and this step is executed only when it is determined that the second terminal side IP address is a pre-appointed IP address.

Specifically, the original SDAP entity of the second message means to query whether the message has been replaced by the SDAP entity, that is, the radio bearer has been adjusted. The transmission control unit queries the memory during detection. If the second message is in If the SDAP entity has been replaced during the downlink process, that is, the SDAP entity has been stored in the memory, the reflection control unit can find in the memory that the second message has the original SDAP entity, otherwise it will not be queried, that is, the second message The original SDAP entity does not exist in the document. Optionally, since the RQI field in the header information of the message that has replaced the SDAP entity in the downlink process is 1, other identifiers can be correspondingly given during the uplink process of the message according to this field, so that the reflection control unit can also According to the other identifier, it is judged whether the message has been replaced by the SDAP entity. After the detection, if the detection result is that the second packet has the original SDAP entity, step S303 is executed, and if the detection result is that the second packet does not have the original SDAP entity, then step S304 is executed.

S303: If the second message has the original SDAP entity of the second message, send a second processing instruction to the original SDAP entity of the second message, and the second processing instruction is used to instruct the second message to be encapsulated and processed and sent to the core网设备。 Net equipment.

In this step, the second packet has the original SDAP entity, which means that the second packet has been replaced by the radio bearer, and the original SDAP entity needs to process the second packet. In this case, the reflection control unit sends a second processing instruction to The original SDAP entity, where the second processing instruction is used to instruct the original SDAP entity to encapsulate the second message and then send it to the core network device, where the encapsulation process means to encapsulate the protocol header related to the second message Information, such as GTP, etc., optionally, after the second packet is encapsulated according to the second processing instruction, the second packet after the encapsulation includes base station-side GTP, UDP, and IP header information, where the GTP header The information includes the second QoS information of the second packet. That is, the GTP, UDP, and IP header information of the base station side is encapsulated in the second packet according to the second processing instruction, and the GTP header information includes the second QoS information of the second packet.

S304: If the original SDAP entity of the second packet does not exist in the second packet, send a second processing instruction to the current SDAP entity of the second packet.

This step is the case that the original SDAP entity of the second message does not exist, which means that the second message has not been replaced by the radio bearer, and the current SDAP entity processes the second message directly, then the reflection control unit sends in this case The second processing instruction is given to the current SDAP entity of the second message, so that the current SDAP entity of the second message encapsulates the second message and sends it to the core network device.

In the message transmission method provided in this embodiment, after the reflection control unit receives the first message sent by the PDCP module, when the second terminal-side IP address carried in the second message is a predetermined IP address, it searches for the Whether the second message has the original SDAP entity of the second message, if it exists, instruct the original SDAP entity to encapsulate and send the second message, if not, instruct the current SDAP entity to encapsulate and send the second message, In this way, the message sent to the core network device is processed by the original SDAP entity, ensuring that the processing traces during the message transmission process are not visible to the "core network" device, and QoS remapping is realized smoother and lower cost. Landing.

After receiving the second message, the reflection control unit will determine whether the second terminal-side IP address carried in the second message belongs to the pre-appointed IP address, and the second terminal-side IP address carried in the second message does not belong to In the case of a pre-appointed IP address, this application also provides an embodiment. In one embodiment, the method includes: if the second terminal-side IP address carried in the second message is not a pre-appointed IP address, then Send the second processing instruction to the current SDAP entity of the second message.

In this embodiment, when the reflection control unit determines that the second terminal-side IP address carried in the second message does not belong to the pre-appointed IP address, that is, the second message is not a pre-appointed message, indicating that the reflection control unit does not The second message is controlled, so the reflection control unit can directly send the second processing instruction to the current SDAP entity of the second message, and let the current SDAP entity to encapsulate and process the second message, and the processed The second message is sent to the core network device. In this way, in the case that the received second message is not an agreed message, there is no need to control to find whether the original SDAP entity exists, which saves processing resources.

For all the embodiments of the uplink data transmission process, this application provides a complete embodiment. As shown in FIG. 4a, the complete embodiment includes:

S21: Receive a message from PDCP, and transfer to S22;
