Detailed ways

In order to make the purpose, technical solutions, and advantages of the present application clearer, the various embodiments of the present application will be described in detail below with reference to the accompanying drawings. However, those of ordinary skill in the art can understand that in each embodiment of the present application, many technical details are proposed in order to enable readers to better understand the present application. However, even without these technical details and various changes and modifications based on the following embodiments, the technical solution claimed in this application can be realized.

The purpose of the embodiments of the present application is to provide a method, system, network device, and storage medium for simultaneous transmission of FTP uplink and downlink services, which can improve the transmission efficiency of simultaneous transmission of FTP uplink and downlink services.

The first embodiment of the present application relates to a method for simultaneous transmission of FTP uplink and downlink services. When the FTP uplink service and the FTP downlink service are simultaneously transmitted, the FTP uplink service and the FTP downlink service are separated into different DRBs.

It should be noted that, in this embodiment, the implementation subject of the FTP uplink and downlink service simultaneous interpretation method is a base station, which is used to communicate with a terminal device, such as a user equipment (UE for short). Optionally, the base station may be a base station in a CDMA system, a base station in a WCDMA system, or an evolved base station in an LTE system, and there is no limitation here.

In the FTP service, the Transmission Control Protocol (TCP) sender maintains a dynamically changing window called the congestion window. The size of the congestion window depends on the degree of congestion of the network. When the network condition is good, the congestion window is constantly changing. With the increase of, the sending window of the TCP sender also increases. In the process of data transmission, TCP samples the round trip time (RTT), and updates the value of the retransmission interval (Retransmission TimeOut, RTO) according to the obtained RTT value. The TCP sender counts each sent data packet, and if the corresponding ACK of the sent data packet is not received within the RTO time, it is determined that the data packet is lost and the data is retransmitted. When the value of RTT is too large, the downstream TCP window will shrink and the downstream TCP traffic will decrease.

In the method for simultaneous transmission of FTP uplink and downlink services provided by this embodiment, when there are simultaneous transmissions of FTP uplink services and FTP downlink services, the FTP uplink services and FTP downlink services are separated into different DRBs. When the FTP uplink service and FTP downlink service are simultaneously transmitted on the same DRB, the ACK of the FTP downlink service is transmitted together with the uplink data of the FTP uplink service. The uplink data of the FTP uplink service will squeeze the bandwidth of the ACK of the FTP downlink service, making FTP The ACK of the downlink service cannot be transmitted to the data sender that provides FTP download in time, and the ACK transmission is not timely, which will cause the downlink TCP window to shrink, which causes the downlink traffic to not increase with the expansion of the TCP window, and ultimately results in the speed of the FTP downlink service. To reach the peak value, therefore, separating the FTP uplink service and the downlink service into different DRBs can prevent the FTP uplink service from occupying the bandwidth required for ACK sending of the FTP downlink service, ensuring that the ACK transmission of the FTP downlink service is timely, and enabling the FTP downlink service It can reach the peak smoothly with the expansion of the TCP window, which improves the transmission efficiency of FTP uplink and downlink service simultaneous interpretation.

The specific flow diagram of the FTP uplink and downlink service simultaneous interpretation method provided by this embodiment is shown in Fig. 1, and includes the following steps:

S101: Determine whether there is simultaneous transmission of the FTP uplink service and the FTP downlink service.

Among them, the simultaneous transmission of FTP uplink service and FTP downlink service means that FTP uplink service and FTP downlink service are transmitted in the same DRB. DRB is a data radio bearer, which is a data transmission channel between a user equipment and a base station. The FTP uplink service includes an acknowledgment character (ACK) for uplink data and uplink data, and the FTP downlink service includes an acknowledgment character (ACK) for downlink data and downlink data.

Please refer to Figure 2, which is a schematic flow diagram of the base station performing FTP uplink and downlink service simultaneous interpretation judgment. Among them, the base station includes the base station user plane and the base station control plane. Specifically, when the base station user plane receives a message, it determines whether it is a TCP message type, if it is, proceed to the next step, if not, end the process; if it is a TCP message type, proceed to the message direction Judge, if it is a downlink message, judge whether an uplink message is received on the DRB, if yes, judge that there is FTP uplink and downlink service simultaneous transmission, notify the base station control plane, if not, end the process; if it is an uplink message , It is judged whether the downlink message is received on the DRB, if it is, it is judged that there is FTP uplink and downlink service simultaneous transmission, and the base station control plane is notified; if not, the process is ended.

Optionally, the base station judges whether the FTP uplink service and the FTP downlink service are simultaneously transmitted, which can be judged by detecting the traffic corresponding to the FTP uplink service and the FTP downlink service. In a specific example, as shown in Figure 3, in S101, that is, before S102, judging whether there is simultaneous transmission of FTP uplink services and FTP downlink services may specifically include:

S1011: Detect whether the flow of the FTP uplink service and the flow of the FTP downlink service both reach the preset flow threshold.

S1012: When the flow of the FTP uplink service and the flow of the FTP downlink service both reach the preset flow threshold, it is determined that the FTP uplink service and the FTP downlink service are simultaneously transmitted.

Among them, the preset flow threshold can be set according to actual needs, such as 10M, 20M, or 50M.

Specifically, the base station detects the FTP uplink service traffic and the FTP downlink service traffic respectively, and compares the detected traffic value with a preset threshold. If the FTP uplink service traffic and the FTP downlink service traffic both reach the preset traffic Threshold, it is determined that the FTP uplink service and the FTP downlink service are simultaneously transmitted at this time. Optionally, the base station detects the FTP uplink service traffic and the FTP downlink service traffic in the same DRB and makes corresponding judgments.

By comparing the detected FTP uplink service and FTP downlink service flow with the preset flow threshold, when both of the flows reach the preset flow threshold, it is determined that the FTP uplink service and the FTP downlink service are simultaneously transmitted, and then FTP is performed. The DRB of the uplink service and the FTP downlink service are separated. In this way, when the preset flow threshold is set in a reasonable range, the flow of the FTP uplink service or the FTP downlink service can be small, and the uplink data of the FTP uplink service has no obvious effect on the ACK of the FTP downlink service. Excluding the situation, the resource consumption of the base station and user equipment is saved when the downlink service transmission efficiency is not greatly affected.

S102: When the FTP uplink service and the FTP downlink service are simultaneously transmitted, separate the FTP uplink service and the FTP downlink service into different DRBs.

Specifically, when the FTP uplink service and the FTP downlink service are simultaneously transmitted, the base station separates the FTP uplink service and the FTP downlink service communicating with the user equipment into different DRBs. Optionally, the base station can migrate the FTP uplink service or the FTP downlink service to the new DRB, thereby achieving the purpose of separating the FTP uplink service and the FTP downlink service into different DRBs.

In a specific example, the FTP uplink service and the FTP downlink service are separated into different DRBs, as shown in Figure 4, which may specifically include:

S1021: Generate reconfiguration information.

S1022: Create a new DRB according to the reconfiguration information.

S1023: Send the reconfiguration information to the user equipment, so that the user equipment migrates the FTP uplink service or the FTP downlink service to the new DRB according to the reconfiguration information.

Among them, the reconfiguration information refers to the information for reallocating DRB to the FTP uplink service or the FTP downlink service.

Specifically, when there is simultaneous transmission of FTP uplink service and FTP downlink service, the base station generates reconfiguration information according to the result of the simultaneous transmission, establishes a new DRB with the user equipment according to the reconfiguration information, and then sends the reconfiguration information to the user equipment. After receiving the reconfiguration information, the user equipment can migrate the corresponding FTP uplink service or FTP downlink service in the reconfiguration information to the new DRB according to the reconfiguration information.

Optionally, the base station may include a base station user plane and a base station control plane. The base station user detects whether the FTP uplink service and the FTP downlink service are simultaneously transmitted. When it is detected that the FTP uplink service and the FTP downlink service are simultaneously transmitted, a notification message is generated and sent. To the base station control plane, the base station control plane generates reconfiguration information according to the notification information and sends it to the base station user plane and user equipment.

Establish a new DRB through the reconfiguration information, and then send the reconfiguration information to the user equipment, so that the user equipment can migrate the FTP uplink service or the FTP downlink service to the new DRB according to the reconfiguration information, so as to achieve the FTP uplink service and FTP downlink service. The purpose of separating services into different DRBs prevents FTP downlink services from being affected by uplink services and improves the efficiency of simultaneous transmission of FTP uplink and downlink services.

Compared with the related technology, the FTP uplink and downlink service simultaneous transmission method provided by this implementation manner separates the FTP uplink service and the FTP downlink service into different DRBs when there are simultaneous transmissions of the FTP uplink service and the FTP downlink service. When the FTP uplink service and FTP downlink service are simultaneously transmitted on the same DRB, the ACK of the FTP downlink service is transmitted together with the uplink data of the FTP uplink service. The uplink data of the FTP uplink service will squeeze the bandwidth of the ACK of the FTP downlink service, making FTP The ACK of the downlink service cannot be transmitted to the data sender that provides FTP download in time, and the ACK transmission is not timely, which will cause the downlink TCP window to shrink, which causes the downlink traffic to not increase with the expansion of the TCP window, and ultimately results in the speed of the FTP downlink service. To reach the peak value, therefore, separating the FTP uplink service and the downlink service into different DRBs can prevent the FTP uplink service from occupying the bandwidth required for ACK sending of the FTP downlink service, ensuring that the ACK transmission of the FTP downlink service is timely, and enabling the FTP downlink service It can reach the peak smoothly with the expansion of the TCP window, which improves the transmission efficiency of FTP uplink and downlink service simultaneous interpretation.

In a specific example, FTP uplink service and FTP downlink service have different QoSFlow identifiers, that is, FTP uplink service and FTP downlink service use different QoSFlow, where QoSFlow is the abbreviation of Quality of Service Flow; In S1023, the reconfiguration information is sent to the user equipment, so that the user equipment migrates the FTP uplink service or the FTP downlink service to the new DRB according to the reconfiguration information, as shown in Figure 5, including:

S10231: Send the reconfiguration information carrying the mapping relationship between QoSFlow and the new DRB to the user equipment.

S10232: Send QoSFlow mapping signaling to the user equipment, so that the user equipment migrates the FTP uplink service or the FTP downlink service to the new DRB according to the mapping signaling, the mapping relationship, and the QoSFlow identifier.

Please refer to FIG. 6, which is a schematic diagram of a process in which a base station sends reconfiguration information to a user equipment. Specifically, based on the detected QoSFlow information, the user plane of the base station determines that there is simultaneous transmission of FTP uplink and downlink services, and then sends a DRB establishment request to the control plane of the base station, and the control plane of the base station sends the DRB establishment request to the radio resource management of the base station. RRM for short), the RRM sends a DRB admission response to the base station control plane, and the base station control plane sends the reconfiguration information carrying the mapping relationship between DRB and QoSFlow to the base station user plane according to the DRB admission response, and the base station user plane sends the reconfiguration information to the user. Device, so that a new DRB is created between the user plane of the base station and the user equipment.

In S10231, the reconfiguration information carries the mapping relationship between QoSFlow and the new DRB. The base station sends the reconfiguration information to the user equipment. After receiving the reconfiguration information, the user equipment stores the mapping relationship between the QoSFlow and the new DRB. For example, the QoSFlow identifier of the FTP upstream service is identifier A, and the QoSFlow identifier of the FTP downstream service is identifier B. If the reconfiguration information is to reconfigure the FTP upstream service, the mapping relationship between the QoSFlow and the new DRB carried in the reconfiguration information It is: the identifier A corresponds to the new DRB.

In S10232, the mapping signaling of QoSFlow refers to the signaling of mapping the FTP uplink service or the FTP downlink service to the new DRB. The base station sends the QoSFlow mapping signaling to the user equipment. Since the user equipment stores the mapping relationship between QoSFlow and the new DRB, it can migrate the FTP uplink service or FTP downlink service to the new one according to the mapping signaling, mapping relationship and QoSFlow identifier. DRB. For example, the mapping signaling is the identification of the new DRB. If the identification of the original DRB is 0 and the identification of the new DRB is 1, then the mapping signaling is "1". After receiving the mapping signaling, the user equipment will use the mapping relationship It can be seen that the service corresponding to the QoSFlow identifier A is migrated to the new DRB with the identifier 1, and then the FTP upstream service is determined according to the identifier A, and then the FTP upstream service is migrated to the new DRB.

Optionally, the QoSFlow mapping signaling may be set in the Service Data Adaptation Protocol (SDAP) protocol header sent by the base station to the user equipment. Optionally, the mapping signaling of QoSFlow is the RDI (Reflective QoS flow to DRB mapping Indication) identifier in the SDAP protocol header.

It is understandable that there are two types of data sent by the base station to the user equipment, one is the downlink data of the FTP downlink service, and the other is the ACK of the uplink data of the FTP uplink service; optionally, when the mapping signaling of QoSFlow is in FTP When the downlink data of the downlink service is sent to the user equipment, the user equipment can learn from the QoSFlow mapping signaling that the FTP downlink service is migrated to the new DRB; when the QoSFlow mapping signaling is sent in the ACK of the uplink data of the FTP uplink service When arriving at the user equipment, the user equipment can learn from the QoSFlow mapping signaling that the QoSFlow mapping signaling is to migrate the FTP uplink service to the new DRB. For example, if the original DRB identifier is 0 and the new DRB identifier is 1, if the mapping signaling of QoSFlow is "1" and sent in the ACK of the uplink data, it means that the DRB of the FTP upstream service is migrated to the identifier. The new DRB is 1. At this time, the mapping relationship is: the identifier A (the QoSFlow identifier of the FTP uplink service) corresponds to the new DRB.

Optionally, if it is to migrate the FTP uplink service to the new DRB, the base station first migrates the ACK of the uplink data in the FTP uplink service to the new DRB, and carries the mapping information in the SDAP message corresponding to the ACK of the uplink data. After receiving the mapping signaling, the user equipment migrates the uplink data of the FTP uplink service to the new DRB to complete the DRB migration; if it is to migrate the FTP downlink service to the new DRB, the base station first transfers the FTP downlink service The downlink data of the FTP is first migrated to the new DRB, and the SDAP message corresponding to the downlink data carries the mapping signaling. After receiving the mapping signaling, the user equipment migrates the ACK of the downlink data of the FTP downlink service to the new DRB. Complete the migration of DRB.

By sending the mapping relationship between QoSFlow and the new DRB and the mapping signaling of QoSFlow to the user equipment, the user equipment can upload the FTP service according to the mapping signaling of QoSFlow, the mapping relationship and the QoSFlow identifier after receiving the mapping signaling of QoSFlow. Or FTP downlink services are migrated to a new DRB, achieving the purpose of separating the FTP uplink services and FTP downlink services that are transmitted at the same time into different DRBs, so that the FTP downlink services will not be affected by the FTP uplink services, and the FTP uplink and downlink services are improved. The efficiency of transmission.

The second embodiment of the present application relates to a method for simultaneous transmission of FTP uplink and downlink services. The second embodiment is roughly the same as the first embodiment, and the main difference is that: in the first embodiment, the FTP uplink service and the FTP downlink service have different QoSFlow identifiers. In the second embodiment of the present application, the FTP uplink service and the FTP downlink service have the same QoSFlow identifier.

Since the FTP uplink service and the FTP downlink service have the same QoSFlow identifier, before separating the FTP uplink service and the FTP downlink service into different DRBs, the FTP uplink service and the FTP downlink service need to be separated into different QoSFlows.

The flow diagram of the FTP uplink and downlink service simultaneous interpretation method provided by this embodiment is shown in Fig. 7, and includes the following steps:

S10231': Send the reconfiguration information carrying the mapping relationship between QoSFlow and the new DRB to the user equipment.

S10232': Allocate a new QoSFlow identifier for the FTP upstream service or FTP downstream service, so that the FTP upstream service and the FTP downstream service have different QoSFlow identifiers.

S10233': Send QoSFlow mapping signaling to the user equipment, so that the user equipment can migrate the FTP uplink service or FTP downlink service to the new DRB according to the mapping signaling, the mapping relationship, and the QoSFlow identifier.

Specifically, the base station sends the reconfiguration information carrying the mapping relationship between QoSFlow and the new DRB to the user equipment, so that the user equipment stores the mapping relationship between QoSFlow and the new DRB; the base station allocates a new QoSFlow for the FTP uplink service or the FTP downlink service. ID, so that FTP uplink service and FTP downlink service have different QoSFlow IDs; the base station sends QoSFlow mapping signaling to the user equipment, so that the user equipment can transfer FTP uplink service or FTP downlink service according to the mapping signaling, mapping relationship and QoSFlow ID Migrate to the new DRB.

By assigning a new QoSFlow identifier for FTP uplink service or FTP downlink service, FTP uplink service and FTP downlink service can be separated in different QoSFlow, and then FTP uplink service or FTP downlink service can be migrated to the new DRB according to the mapping signaling. It can achieve the purpose of separating the FTP uplink service and the FTP downlink service into different DRBs for transmission, so that the FTP downlink service will not be affected by the FTP uplink service, and the efficiency of the FTP uplink and downlink service simultaneous transmission is improved.

The following takes the scenario of migrating to the new DRB as an FTP uplink service as an example for specific description.

Please refer to FIG. 8, which is a schematic diagram of simultaneous transmission of FTP uplink service and FTP downlink service in the prior art. As shown in Figure 8, the ACK of the uplink data and the ACK of the FTP uplink service and the downlink data of the FTP downlink service and the ACK of the downlink data are simultaneously transmitted in the same DRB. Because the ACK of the downlink data and the uplink data are all passed by the user equipment The base station sends to the core network, so the uplink data will squeeze the bandwidth of the ACK of the downlink data, so that the ACK of the downlink data cannot be sent to the core network in time, which affects the peak of the downlink data.

The base station can specifically include the base station user plane and the base station control plane. The base station user plane first detects the simultaneous transmission of FTP uplink services and FTP downlink services. When the simultaneous transmission of FTP uplink services and FTP downlink services is detected, notification information is generated and sent to the base station control surface. After receiving the notification information, the base station control plane sends signaling to the base station user plane and user equipment, so that the base station user plane and user equipment create a new DRB.

Then, the user plane of the base station migrates the ACK packet of the uplink data of the FTP uplink service to the new DRB for transmission, and sets the RDI identifier in the SDAP protocol layer of the ACK packet of the uplink data to 2. Upstream services are migrated to the new DRB2. As shown in Figure 9, the base station user plane first migrates the ACK of uplink data from the original DRB1 to the new DRB2. Please also refer to FIG. 10, which is an example diagram of the position of the RDI in the SDAP protocol layer message.

When the user equipment receives the ACK packet of the uplink data, and knows that the RDI identifier in the ACK packet of the uplink data is 2, it will also migrate the uplink data packet to the new DRB, as shown in Figure 11, which implements the FTP The uplink service and the FTP downlink service are separated into different DRBs for transmission purposes.

The division of the steps of the various methods above is only for clarity of description. When implemented, it can be combined into one step or some steps can be split into multiple steps. As long as they contain the same logical relationship, they are all within the scope of protection of this patent. ; Adding insignificant modifications to the algorithm or process or introducing insignificant design, but not changing the core design of the algorithm and process are within the scope of protection of the patent.
