Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, embodiments of the present invention will be described in detail below with reference to the accompanying drawings. However, it will be appreciated by those of ordinary skill in the art that numerous technical details are set forth in order to provide a better understanding of the present application in various embodiments of the present invention. However, the technical solution claimed in the present application can be implemented without these technical details and various changes and modifications based on the following embodiments.
The first embodiment of the invention relates to a method for simultaneously transmitting an FTP uplink service and an FTP downlink service, which separates the FTP uplink service and the FTP downlink service to different DRBs when the FTP uplink service and the FTP downlink service are simultaneously transmitted.
It should be noted that, in this embodiment, the main implementation body of the FTP uplink and downlink service concurrent transmission method is a base station, which is used for communicating with a terminal device, such as a User Equipment (UE). Optionally, the base station may be a base station in a CDMA system, a base station in a WCDMA system, or an evolved node base station in an LTE system, which is not limited herein.
In the FTP service, a Transmission Control Protocol (TCP) sender maintains a dynamically changing window called a congestion window, the size of the congestion window depends on the congestion level of the network, and when the network condition is good, the congestion window is continuously increased, and the sending window of the TCP sender is also increased. TCP samples Round Trip communication delay (RTT) during data transmission, and updates a Retransmission interval (RTO) value according to the obtained RTT value. And the TCP sending end times each sent data packet, and if the corresponding ACK of the sent data packet is not received within the RTO time, the data packet is judged to be lost and the data is retransmitted. When the RTT value is too large, the downlink TCP window may shrink, so that the downlink TCP traffic is reduced.
In the FTP uplink and downlink service simultaneous transmission method provided by the embodiment, when there is simultaneous transmission of the FTP uplink service and the FTP downlink service, the FTP uplink service and the FTP downlink service are separated to different DRBs. Because ACK of the FTP downlink service and uplink data of the FTP uplink service are transmitted together when the FTP uplink service and the FTP downlink service are transmitted simultaneously on one DRB, the uplink data of the FTP uplink service occupies the bandwidth of the ACK of the FTP downlink service, so that ACK of FTP downlink service can not be transmitted to the data transmitting end providing FTP download in time, and the downlink TCP window can shrink due to the untimely transmission of ACK, thereby causing that the downlink flow can not be improved along with the expansion of the TCP window, and finally causing that the speed of the FTP downlink service can not reach the peak value, therefore, separating the FTP uplink service and the downlink service into different DRBs, the FTP uplink service can not occupy the bandwidth required by the ACK transmission of the FTP downlink service, ensure the ACK transmission of the FTP downlink service in time, the FTP downlink service can successfully reach the peak value along with the expansion of the TCP window, and the transmission efficiency of the simultaneous transmission of the FTP downlink service and the FTP uplink service is improved.
A specific flowchart of the FTP uplink and downlink service concurrent transmission method provided by the embodiment is shown in fig. 1, and includes the following steps:
s101: and judging whether the FTP uplink service and the FTP downlink service are simultaneously transmitted.
The FTP uplink service and the FTP downlink service are transmitted simultaneously, which means that the FTP uplink service and the FTP downlink service are transmitted in the same DRB. The DRB is a Data Radio Bearer (Data Radio Bearer) and is a Data transmission channel between the user equipment and the base station. The FTP uplink service comprises uplink data and Acknowledgement Characters (ACK) of the uplink data, and the FTP downlink service comprises downlink data and Acknowledgement Characters (ACK) of the downlink data.
Please refer to fig. 2, which is a schematic flow chart illustrating the process of the base station performing the FTP uplink and downlink service simultaneous transmission determination. The base station comprises a base station user plane and a base station control plane. Specifically, when the base station user plane receives a message, whether the message is of a TCP message type is judged, if so, the next judgment is carried out, and if not, the process is ended; if the message type is a TCP message type, judging the message direction, if the message type is a downlink message, judging whether an uplink message is received on the DRB, if so, judging that the simultaneous transmission of the FTP uplink and downlink services exists, informing a control plane of a base station, and if not, ending the flow; if the message is an uplink message, judging whether a downlink message is received on the DRB, if so, judging that the FTP uplink and downlink service simultaneous transmission exists, informing a control plane of the base station, and if not, ending the process.
Optionally, the base station determines whether there is simultaneous transmission of the FTP uplink service and the FTP downlink service, and may determine by detecting traffic corresponding to the FTP uplink service and the FTP downlink service. In a specific example, as shown in fig. 3, in S101, that is, before S102, the determining whether there is simultaneous transmission of the FTP uplink service and the FTP downlink service may specifically include:
s1011: and detecting whether the flow of the FTP uplink service and the flow of the FTP downlink service both reach preset flow thresholds.
S1012: and when the flow of the FTP uplink service and the flow of the FTP downlink service both reach preset flow thresholds, judging that the FTP uplink service and the FTP downlink service are simultaneously transmitted.
The preset flow threshold may be set according to actual needs, and is, for example, 10M, 20M, or 50M.
Specifically, the base station detects the flow of the FTP uplink service and the flow of the FTP downlink service respectively, compares the detected flow values with a preset threshold, and determines that the FTP uplink service and the FTP downlink service are simultaneously transmitted at the moment if the flow of the FTP uplink service and the flow of the FTP downlink service both reach the preset flow threshold. Optionally, the base station detects and correspondingly determines the traffic of the FTP uplink service and the traffic of the FTP downlink service in the same DRB.
Comparing the detected flow of the FTP uplink service and the FTP downlink service with a preset flow threshold, when the flow of the FTP uplink service and the flow of the FTP downlink service both reach the preset flow threshold, judging that the FTP uplink service and the FTP downlink service are transmitted simultaneously, and then performing DRB separation of the FTP uplink service and the FTP downlink service. Therefore, when the preset flow threshold is set in a reasonable range, the situations that the flow of the FTP uplink service or the FTP downlink service is small and the occupation effect of the uplink data of the FTP uplink service on the ACK of the FTP downlink service is not obvious can be excluded, and the resource consumption of the base station and the user equipment is saved under the condition that the influence on the transmission efficiency of the lower service is not large.
S102: and when the FTP uplink service and the FTP downlink service are transmitted simultaneously, separating the FTP uplink service and the FTP downlink service to different DRBs.
Specifically, when there is simultaneous transmission of the FTP uplink service and the FTP downlink service, the base station separates the FTP uplink service and the FTP downlink service communicated with the user equipment to different DRBs. Optionally, the base station may migrate the FTP uplink service or the FTP downlink service to a new DRB, so as to achieve the purpose of separating the FTP uplink service and the FTP downlink service to different DRBs.
In a specific example, separating the FTP uplink service and the FTP downlink service into different DRBs, as shown in fig. 4, may specifically include:
s1021: and generating reconfiguration information.
S1022: and establishing a new DRB according to the reconfiguration information.
S1023: and sending the reconfiguration information to the user equipment, so that the user equipment transfers the FTP uplink service or the FTP downlink service to a new DRB according to the reconfiguration information.
The reconfiguration information refers to information for reallocating the DRB to the FTP uplink service or the FTP downlink service.
Specifically, when there is simultaneous transmission of the FTP uplink service and the FTP downlink service, the base station generates reconfiguration information according to a 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 may migrate the corresponding FTP uplink service or FTP downlink service in the reconfiguration information to a new DRB according to the reconfiguration information.
Optionally, the base station may include a base station user plane and a base station control plane, where the base station user plane detects whether the FTP uplink service and the FTP downlink service are transmitted simultaneously, and when detecting that the FTP uplink service and the FTP downlink service are transmitted simultaneously, generates notification information and sends the notification information to the base station control plane, and the base station control plane generates reconfiguration information according to the notification information and sends the reconfiguration information to the base station user plane and the user equipment.
The new DRB is established through the reconfiguration information, and the reconfiguration information is sent to the user equipment, so that the user equipment can transfer the FTP uplink service or the FTP downlink service to the new DRB according to the reconfiguration information, the purpose of separating the FTP uplink service and the FTP downlink service to different DRBs is achieved, the FTP downlink service is not influenced by the uplink service, and the efficiency of simultaneous transmission of the FTP uplink service and the FTP downlink service is improved.
Compared with the related art, the FTP uplink and downlink service simultaneous transmission method provided by the embodiment separates the FTP uplink service and the FTP downlink service to different DRBs when the FTP uplink service and the FTP downlink service are transmitted simultaneously. Because ACK of the FTP downlink service and uplink data of the FTP uplink service are transmitted together when the FTP uplink service and the FTP downlink service are transmitted simultaneously on one DRB, the uplink data of the FTP uplink service occupies the bandwidth of the ACK of the FTP downlink service, so that ACK of FTP downlink service can not be transmitted to the data transmitting end providing FTP download in time, and the downlink TCP window can shrink due to the untimely transmission of ACK, thereby causing that the downlink flow can not be improved along with the expansion of the TCP window, and finally causing that the speed of the FTP downlink service can not reach the peak value, therefore, separating the FTP uplink service and the downlink service into different DRBs, the FTP uplink service can not occupy the bandwidth required by the ACK transmission of the FTP downlink service, ensure the ACK transmission of the FTP downlink service in time, the FTP downlink service can successfully reach the peak value along with the expansion of the TCP window, and the transmission efficiency of the simultaneous transmission of the FTP downlink service and the FTP uplink service is improved.
In a specific example, the FTP uplink Service and the FTP downlink Service have different QoSFlow identities, that is, the FTP uplink Service and the FTP downlink Service use different QoSFlow, where QoSFlow is an abbreviation of Quality of Service data Flow (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 a new DRB according to the reconfiguration information, as shown in fig. 5, including:
s10231: and sending reconfiguration information carrying the mapping relation between the QoSFlow and the new DRB to the user equipment.
S10232: and sending the QoSFlow mapping signaling to the user equipment, and enabling the user equipment to transfer the FTP uplink service or the FTP downlink service to a new DRB according to the mapping signaling, the mapping relation and the QoSFlow identifier.
Please refer to fig. 6, which is a schematic diagram illustrating a process of sending reconfiguration information to a ue by a base station. Specifically, the base station user plane determines that there is FTP uplink and downlink service concurrent transmission according to the detected QoSFlow information, and then sends a DRB establishment request to the base station control plane, the base station control plane sends the DRB establishment request to a Radio Resource Management (RRM) of the base station, the RRM sends a DRB admission response to the base station control plane, the base station control plane sends reconfiguration information carrying a mapping relationship between the DRB and the 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 equipment, so that a new DRB is established between the base station user plane and the user equipment.
In S10231, the reconfiguration information carries a mapping relationship between QoSFlow and a new DRB, the base station sends the reconfiguration information to the user equipment, and the user equipment stores the mapping relationship between QoSFlow and the new DRB after receiving the reconfiguration information. For example, the QoSFlow identifier of the FTP uplink service is identifier a, the QoSFlow identifier of the FTP downlink service is identifier B, and if the reconfiguration information is to reconfigure the FTP uplink service, the mapping relationship between the QoSFlow carried in the reconfiguration information and the new DRB is as follows: identity a corresponds to the new DRB.
In S10232, the mapping signaling of QoSFlow is signaling for mapping the FTP uplink service or the FTP downlink service to a new DRB. And the base station sends the QoSFlow mapping signaling to the user equipment, and the user equipment stores the mapping relation between the QoSFlow and the new DRB, so that the FTP uplink service or the FTP downlink service can be migrated to the new DRB according to the mapping signaling, the mapping relation and the QoSFlow identifier. For example, the mapping signaling is an identifier of a new DRB, if the original DRB identifier is 0 and the new DRB identifier is 1, the mapping signaling is "1", after receiving the mapping signaling, the user equipment knows that the service corresponding to the QoSFlow identifier a is migrated to the new DRB identifier 1 according to the mapping relationship, determines the service as an FTP uplink service according to the identifier a, and then migrates the FTP uplink service to the new DRB.
Alternatively, the mapping signaling of the QoSFlow may be set in a Service Data Adaptation Protocol (SDAP) Protocol header sent by the base station to the ue. Optionally, the mapping signaling of QoSFlow is an rdi (reflective QoS flow to DRB mapping indication) identifier in the SDAP protocol header.
It can be understood that there are two types of data sent by the base station to the user equipment, one is downlink data of the FTP downlink service, and the other is ACK of uplink data of the FTP uplink service; optionally, when the mapping signaling of QoSFlow is sent to the user equipment in the downlink data of the FTP downlink service, the user equipment may learn, according to the mapping signaling of QoSFlow, that the FTP downlink service is migrated to a new DRB; when the mapping signaling of QoSFlow is sent to the user equipment in the ACK of the uplink data of the FTP uplink service, the user equipment may know that the mapping signaling of QoSFlow is to migrate the FTP uplink service to a new DRB according to the mapping signaling of QoSFlow. For example, if the original DRB identifier is 0 and the new DRB identifier is 1, and if the mapping signaling of QoSFlow is "1" and is sent in the uplink ACK, the method refers to migrating the DRB of the FTP uplink service to the new DRB identifier of 1, and at this time, the mapping relationship is: identity a (QoSFlow identity for FTP uplink traffic) corresponds to the new DRB.
Optionally, if the FTP uplink service is migrated to a new DRB, the base station migrates ACK of uplink data in the FTP uplink service to the new DRB first, where an SDAP message corresponding to the ACK of the uplink data carries a mapping signaling, and after receiving the mapping signaling, the user equipment migrates the uplink data of the FTP uplink service to the new DRB, thereby completing migration of the DRB; if the FTP downlink service is migrated to the new DRB, the base station migrates the downlink data of the FTP downlink service to the new DRB first, the SDAP message corresponding to the downlink data carries a mapping signaling, and the user equipment migrates the ACK of the downlink data of the FTP downlink service to the new DRB after receiving the mapping signaling, so as to complete the migration of the DRB.
By sending the mapping relation between the QoSFlow and the new DRB and the mapping signaling of the QoSFlow to the user equipment, the user equipment can migrate the FTP uplink service or the FTP downlink service to the new DRB according to the mapping signaling, the mapping relation and the QoSFlow mark of the QoSFlow after receiving the mapping signaling of the QoSFlow, thereby achieving the purpose of separating the FTP uplink service and the FTP downlink service which are transmitted at the same time to different DRBs, so that the FTP downlink service is not influenced by the FTP uplink service, and the efficiency of the simultaneous transmission of the FTP uplink service and the FTP downlink service is improved.
The second embodiment of the invention relates to a method for simultaneously transmitting the FTP uplink and downlink services. The second embodiment is substantially the same as the first embodiment, and mainly differs therefrom in that: in the first embodiment, the FTP upstream traffic and the FTP downstream traffic have different QoSFlow identities. In the second embodiment of the present invention, the FTP uplink service and the FTP downlink service have the same QoSFlow identifier.
Because 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 to different DRBs, the FTP uplink service and the FTP downlink service need to be separated in different QoSFlow.
Fig. 7 shows a flow diagram of the FTP uplink and downlink service simultaneous transmission method according to the present embodiment, which includes the following steps:
s10231': and sending reconfiguration information carrying the mapping relation between the QoSFlow and the new DRB to the user equipment.
S10232': and distributing a new QoSFlow identifier for the FTP uplink service or the FTP downlink service, so that the FTP uplink service and the FTP downlink service have different QoSFlow identifiers.
S10233': and sending the QoSFlow mapping signaling to the user equipment, and enabling the user equipment to transfer the FTP uplink service or the FTP downlink service to a new DRB according to the mapping signaling, the mapping relation and the QoSFlow identifier.
Specifically, the base station sends reconfiguration information carrying the mapping relationship between the QoSFlow and the new DRB to the user equipment, so that the user equipment stores the mapping relationship between the QoSFlow and the new DRB; the base station distributes a new QoSFlow mark for the FTP uplink service or the FTP downlink service, so that the FTP uplink service and the FTP downlink service have different QoSFlow marks; and the base station sends the QoSFlow mapping signaling to the user equipment, so that the user equipment can transfer the FTP uplink service or the FTP downlink service to a new DRB according to the mapping signaling, the mapping relation and the QoSFlow identifier.
Optionally, if the FTP uplink service is migrated to a new DRB, the base station migrates ACK of uplink data in the FTP uplink service to the new DRB first, where an SDAP message corresponding to the ACK of the uplink data carries a mapping signaling, and after receiving the mapping signaling, the user equipment migrates the uplink data of the FTP uplink service to the new DRB, thereby completing migration of the DRB; if the FTP downlink service is migrated to the new DRB, the base station migrates the downlink data of the FTP downlink service to the new DRB first, the SDAP message corresponding to the downlink data carries a mapping signaling, and the user equipment migrates the ACK of the downlink data of the FTP downlink service to the new DRB after receiving the mapping signaling, so as to complete the migration of the DRB.
By allocating a new QoSFlow identifier to the FTP uplink service or the FTP downlink service, the FTP uplink service and the FTP downlink service can be separated in different QoSFlow, and then the FTP uplink service or the FTP downlink service is transferred to a new DRB according to the mapping signaling, so that the purpose of separating the FTP uplink service and the FTP downlink service to different DRBs for transmission can be achieved, the FTP downlink service is not influenced by the FTP uplink service, and the efficiency of simultaneously transmitting the FTP uplink service and the FTP downlink service is improved.
The following describes a scenario in which the migration to the new DRB is an FTP uplink service specifically.
Please refer to fig. 8, which is a schematic diagram illustrating the simultaneous transmission of the FTP uplink service and the FTP downlink service in the prior art. As shown in fig. 8, uplink data and ACK of the FTP uplink service and downlink data and ACK of the FTP downlink service are simultaneously transmitted in the same DRB, and since both the ACK of the downlink data and the uplink data are sent to the core network by the user equipment through the base station, the uplink data may occupy 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, thereby affecting the downlink data to reach a peak value.
The base station may specifically include a base station user plane and a base station control plane, where the base station user plane detects simultaneous transmission of the FTP uplink service and the FTP downlink service, and generates notification information to send to the base station control plane when detecting that the FTP uplink service and the FTP downlink service are transmitted simultaneously. And after receiving the notification information, the control plane of the base station sends signaling to the user plane of the base station and the user equipment, so that the user plane of the base station and the user equipment create a new DRB.
Then, the base station user plane migrates the ACK message of the uplink data of the FTP uplink service to the new DRB for transmission, sets the RDI identifier in the SDAP protocol layer of the ACK message of the uplink data to 2, and migrates the FTP uplink service to the new DRB2 through the user equipment. As shown in fig. 9, the base station user plane first migrates the ACK of the uplink data from the original DRB1 to the new DRB 2. Please refer to fig. 10, which is an exemplary diagram of the location of RDI in the SDAP protocol layer message.
When the user equipment receives the ACK packet of the uplink data, it learns that the RDI in the ACK packet of the uplink data is 2, and then migrates the uplink data packet to a new DRB, as shown in fig. 11, so as to achieve the purpose of separating the FTP uplink service and the FTP downlink service to different DRBs for transmission.
The steps of the above methods are divided for clarity, and the implementation may be combined into one step or split some steps, and the steps are divided into multiple steps, so long as the steps contain the same logical relationship, which is within the protection scope of the present patent; it is within the scope of the patent to add insignificant modifications to the algorithms or processes or to introduce insignificant design changes to the core design without changing the algorithms or processes.
