The following several specific embodiments may be combined with each other, and details of the same or similar concepts or processes may not be repeated in some embodiments. It should be noted that in the message transmission method provided in the present application, the execution main bodies of fig. 2 to fig. 4 are reflection control units, where the execution main body may also be a base station, and the reflection control unit may be implemented as part or all of the base station by software, hardware, or a combination of software and hardware.
In order to make the objects, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in 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 obvious that the described embodiments are some embodiments of the present application, but not all embodiments.
In an embodiment, fig. 2 provides a message transmission method, where this embodiment relates to a specific process of adjusting a transmission priority of a message according to an IP (Internet Protocol) address carried in a first message after a reflection control unit receives the first message sent by a core network device, and as shown in fig. 2, the method includes:
s101, receiving a first message sent by core network equipment; the first message carries the IP address of the first terminal side and the first QoS information.
In this embodiment, the core network device represents a device on the 5G core network side, for example, the 5G core network device includes a device for implementing an Access and Mobility Management Function (AMF) and a User Plane Function (UPF). The first message represents a message sent by a core network device to an SDAP module in a 5G access network, where the first message is only used for distinguishing from a second message sent by a PDCP module in the 5G access network (in a base station) in the following embodiment (without limiting a sequence and a sequence number of the message), and it should be noted that all of the first and second equalizations in this embodiment are used for distinguishing, for example, an IP address of a first terminal side, an IP address of a second terminal side and first QoS information in the following description, and second QoS information in the following description are only used for distinguishing.
Specifically, in practical application, a reflection control unit in an SDAP module of a base station receives a first packet sent by a core network device, where the first packet may be a GPRS Tunneling Protocol (GTP) packet, and the first packet carries a first terminal side IP address and first QoS information, where the QoS information includes information related to flow classification, flow supervision, flow shaping, interface speed limit, congestion management, and congestion avoidance of the first packet, for example, an SDAP entity and a Radio Bearer (RB) that can obtain the packet from the first QoS information, and a priority of each RB, and this embodiment does not limit this.
S102, if the IP address of the first terminal side is the pre-agreed IP address, judging whether the priority of the current RB of the first message is the highest priority or not according to the first QoS information.
The embodiment of the present application is directed to improving transmission quality of a specific IP service stream, and therefore, after receiving a first packet, it is required to first determine whether the first packet is a specific IP service stream, that is, determine whether an IP address at a first terminal side carried in the first packet is a pre-agreed IP address, and only if the first packet is a pre-agreed IP address, a reflection control unit controls transmission priority of the first packet.
Specifically, based on the first message received in S101, if the IP address of the first terminal side in the first message is the pre-agreed IP address, the reflection control unit searches the current RB from the first QoS information carried in the first message, and determines 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 may 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 determines 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 determination result is obtained, if the determination result is that the priority of the current RB is the highest priority, step S103 is performed, and if the determination result is that the priority of the current RB is not the highest priority, step S104 is performed.
It should be noted that, before the priority of the current RB is not the highest priority, the reflection control unit further needs to determine whether the first packet has multiple RBs at present, if there is only one RB, the reflection control unit does not need to perform subsequent steps, and directly sends the first processing instruction to the current SDAP entity of the first packet, and if the first packet has multiple RBs, determines whether the priority of the current RB is the highest priority.
S103, if the priority of the current RB is the highest priority, a first processing instruction is sent to the current SDAP entity of the first message, and the first processing instruction is used for indicating that the first message is sent to the PDCP module after being packaged.
In this step, if the determination result is that the priority of the current RB is the highest priority, the current SDAP entity of the first packet of the reflection control unit sends a first processing instruction, where the first processing instruction is used to instruct the first packet to be sent to the PDCP module after being encapsulated. Wherein, the current SDAP entity of the first message is obtained from the first QoS information by the reflection control unit. In an example, after receiving the first processing instruction, the current SDAP entity encapsulates the first packet into an encapsulated SDAP header information, and sends the encapsulated first packet to the PDCP module in an SDAP PDU session.
S104, if the priority of the current RB is not the highest priority, selecting a new SDAP entity according to the first QoS information, and sending 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, if the determination result indicates that the priority of the current RB is not the highest priority, 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 indicates the SDAP entity corresponding to the RB with the highest priority, and accordingly, when the first packet is not transmitted with the highest priority, the first packet is controlled to be transmitted with the highest priority. Specifically, after selecting a new SDAP entity according to the first QoS information, the reflection control unit sends a first processing instruction to the new SDAP entity, and after receiving the first processing instruction, the new SDAP entity encapsulates the first message into encapsulated SDAP header information and sends the encapsulated first message to the PDCP module in SDAP PDU session.
In the packet transmission method provided in this embodiment, when the IP address of the packet is a pre-agreed IP address, the reflection control unit determines that the priority of the packet in the current RB is the highest priority, and controls the current SDAP entity to perform encapsulation processing on the packet and transmit the packet, and when the priority of the current RB of the packet is not the highest priority, determines a new SDAP entity according to the RB with the highest priority again, and controls the new entity to perform encapsulation processing on the packet and transmit the packet.
In view of the above, an embodiment is provided when the first packet is encapsulated with the SDAP header information according to the first processing instruction, and an RQ I (Reflective QoS Indication) field in the SDAP header is different according to different values of the SDAP entity, where in an embodiment, if the first processing instruction is sent to a current SDAP entity of the first packet, the RQ I field in the encapsulated SDAP header information of the first packet is a first value; if the first processing instruction is sent to a new SDAP entity, the RQI field in the SDAP header information of the first message after encapsulation processing is a second value; wherein the first value and the second value are different values.
For example, if the current SDAP entity encapsulates the SDAP header information to the first packet, the RQI field is set to 0, and if the selected new SDAP entity encapsulates the SDAP header information to the first packet, the RQI field is set to 1, so that after receiving the first packet, the downstream protocol can distinguish whether the SDAP entity is replaced according to the RQI value.
In the foregoing embodiment, if the precondition that the reflection control unit determines whether the priority of the current RB of the first packet is the highest priority according to the first QoS information is to determine that the first terminal side IP address carried in the received first packet belongs to the pre-agreed IP address, but for a case that the first terminal side IP address carried in the first packet does not belong to the pre-agreed IP address, the present application also provides an embodiment, and in an embodiment, the method includes: and if the first terminal side IP address is not the pre-agreed IP address, sending a first processing instruction to the current SDAP entity of the first message. In this embodiment, when the reflection control unit determines that the IP address of the first terminal side carried in the first packet does not belong to the pre-agreed IP address, that is, the first packet is not a pre-agreed packet, it indicates that the reflection control unit does not control the bearer priority thereof, so that the reflection control unit directly sends the first processing instruction to the current SDAP entity of the first packet, and the current SDAP entity performs encapsulation processing on the first packet and sends the processed first packet to the PDCP module.
In the above embodiment, when the priority of the current RB is not the highest priority in step S104, the reflection control unit needs to select a new SDAP entity according to the first QoS information, and as to a specific process of the reflection control unit selecting a new SDAP entity, the application provides an embodiment, and in an embodiment, as shown in fig. 3, the "selecting a new SDAP entity according to the first QoS information" in step S104 includes:
s201, acquiring current SDAP entity of the first message and R B information of the first message according to the first QoS information; the RB information of the first packet includes the current RB of the first packet, R B other than the current RB, and the priority identifier of the current RB and other RBs.
In this embodiment, the first packet carries first QoS information, and the reflection control unit obtains, from the first QoS information, a current SDAP entity of the first packet and RB information of the first packet, where one packet may correspond to multiple RBs, and the RB information of the first packet includes a current RB of the first packet, other RBs except the current R B, and priority identifiers of all RBs, where the priority identifiers of all RBs may be identifiers in a form of a character, a letter, a number, or various combinations, which is not limited in this embodiment.
S202, selecting the RB with the highest priority from other RBs according to the priority identification.
Since the priority of the current RB is not the highest priority in this embodiment, based on the priority identifier of the RB obtained in step S201, the reflection control unit selects the highest priority RB from the other RBs, so as to ensure that the priority of the bearer of the first packet is the highest.
S203, the SDAP entity of the QoS flow corresponding to the RB with the highest priority is determined as a new SDAP entity.
Based on the RB with the highest priority selected in step S202, the reflection control unit determines the SDAP entity corresponding to the RB with the highest priority as a new SDAP entity, specifically, the reflection control unit selects any QoS flow corresponding to the RB with the highest priority, and the SDAP entity of the any QoS flow is the SDAP entity corresponding to the RB with the highest priority.
In the packet 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 packet, and determines the SDAP entity corresponding to the RB with the highest priority as a new SDAP entity, so as to control the bearer of the first packet to be the highest priority, and control the SDAP entity corresponding to the bearer with the highest priority to process the first packet, thereby improving the transmission quality of the first packet.
After the reflection control unit selects a new SDAP entity according to the first QoS information, which corresponds to the current SDAP entity replacing the first packet, in this case, the current SDAP entity replaced by the first packet becomes the original SDAP entity of the SDAP, and in one embodiment, the method further includes: and determining the current SDAP entity of the first message as the original SDAP entity of the first message, and storing.
In this embodiment, if the new SDAP entity is replaced with the SDAP entity of the first packet, the current SDAP entity becomes the original SDAP entity, and the reflection control unit needs to store the original SDAP entity to record the replacement record of the SDAP entity of the first packet, thereby facilitating subsequent query.
All the embodiments described above belong to a downlink data transmission process based on a flow direction of a message from a 5G core network device to an SDAP module of a 5G access network and then to a PDCP module of the 5G access network, and for all embodiments of the downlink data transmission process, the present application provides a complete embodiment, and as shown in fig. 3a, the complete embodiment includes:

s12, removing the IP/UDP (User Datagram Protocol)/GTP head overhead of the base station, and turning to S13;
s13, searching the current SDAP entity and RB information thereof according to the QoS information carried in the GTP header, and turning to S14;

s19, the current SDAP entity searched by the QoS information processes the packet, i.e., encapsulates the SDAP header and S10, and sends the processed packet to the corresponding PDCP module as an SDAP PDU (Protocol Data Unit).
The packet transmission method provided in this embodiment only relates to deep processing optimization inside the base station, and a comparison between before and after the specific optimization is shown in fig. 3b, where a specific implementation process in this embodiment is the same as that in all the embodiments described above, and is not described herein again, because an execution main body of all steps in this embodiment is a reflection control unit disposed in the SDAP module, the reflection control unit is specially responsible for IP streaming of a service appointment, in wireless transmission, priority is promoted to RB bearer with the highest priority, and the whole process is executed in the base station, that is, a customer experience of a specific service is actively ensured to the maximum extent from a base station perspective.
In addition, in practical application, there is also an uplink data transmission process, that is, a flow direction from the PDCP module of the 5G access network to the SDAP module of the 5G access network to the 5G core network device is repeated for part of the content and the content in the above uplink data transmission process embodiment, and therefore, the repeated content will not be described again. This flow-through process provides one embodiment of the present application, as shown in fig. 4, the method further comprising:
s301, receiving a second message sent by the PDCP module; the second message carries the IP address of the second terminal side.
In this embodiment, the reflection control unit in the 5G access network SDAP module receives the second packet sent by the PDCP module, where the second packet is already described in step S101, and the second packet is not limited to a packet sequence or a sequence number, but is distinguished from the first packet. Wherein, the second message carries the IP address of the second terminal side.
S302, if the IP address of the second terminal side is the pre-agreed IP address, whether the second message has the original SDAP entity of the second message is detected.
Based on the second message received in step S301, the reflection control unit detects whether the second message has the original SDAP entity of the second message when the second terminal side IP address in the second message is the pre-agreed IP address, and this step is performed when the second terminal side IP address in the second message is the pre-agreed IP address, so that the reflection control unit needs to determine whether the second terminal side IP address is the pre-agreed IP address after receiving the second message, and only performs this step when determining that the second terminal side IP address is the pre-agreed I P address.
Specifically, the original SDAP entity of the second packet indicates whether the packet is to be queried as to whether the SDAP entity is replaced, that is, the radio bearer is adjusted, the transmission control unit queries in the memory when detecting, and if the second packet is replaced with the SDAP entity in the downlink process, that is, the SDAP entity is stored in the memory, the reflection control unit may find that the second packet has the original SDAP entity in the memory, or else, the reflection control unit may not query, that is, the second packet does not have the original SDAP entity. Optionally, as for the message with the replaced SDAP entity in the downlink process, the RQI field in the header information of the message is 1, other identifiers may be correspondingly provided according to the RQI field in the uplink process of the message, so that the reflection control unit may also determine whether the message has the replaced SDAP entity according to the other identifiers. And after the detection, if the detection result indicates that the second message has the original SDAP entity, executing the step S303, and if the detection result indicates that the second message has no original SDAP entity, executing the step S304.
S303, if the second packet has the original SDAP entity of the second packet, send a second processing instruction to the original SDAP entity of the second packet, where the second processing instruction is used to instruct the core network device to send the second packet after being encapsulated.
If the second packet has the original SDAP entity, 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 packet and send the second packet to the core network device, where the encapsulation indicates that the second packet is encapsulated with related protocol header information, such as GTP, and optionally, after the second packet is encapsulated according to the second processing instruction, the encapsulated second packet includes base station side GTP, UDP, and IP header information, where the GTP header information includes second QoS information of the second packet. That is, 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 second message does not have the original SDAP entity of the second message, a second processing instruction is sent to the current SDAP entity of the second message.
In this step, the second message does not have the original SDAP entity, which means that the second message is not replaced by a radio bearer, and the current SDAP entity processes the second message directly, and then the reflection control unit sends a second processing instruction 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 the second message to the core network device.
In the packet transmission method provided in this embodiment, after the reflection control unit receives the first packet sent by the PDCP module, when the IP address of the second terminal side carried in the second packet is the predetermined IP address, it is searched whether the second packet has the original SDAP entity of the second packet, if yes, the original SDAP entity is instructed to perform encapsulation sending processing on the second packet, and if not, the current SDAP entity is instructed to perform encapsulation sending processing on the second packet.
