Therefore, the evaluation and optimization work for 5G networks also needs to be developed synchronously. In an index system for evaluating the quality of a wireless network, the most intuitive index for reflecting the quality of the network is the rate experienced by a user.

The 5G network application scenes are diversified, and different application scenes have different demands on the network. Wherein, the differentiated service can be realized by slicing and other technologies on the core network side. For the radio access network side, differentiated services are mainly realized by depending on service scheduling of different 5G service quality identifiers (5G quality of service identifier,5QI), namely different 5 QIs are configured for transmission data of different service types. Therefore, it is very necessary to count the user perceived rate at granularity of distinguishing 5QI. At present, in the downlink data transmission process, the calculation of the user perception rate of the transmission data of different service types can distinguish 5QI for statistics.

In embodiments of the present invention, the depiction is primarily based on a 5G network. As shown in fig. 2, fig. 2 is a schematic diagram of a 5G network architecture. The 5G network architecture includes a radio access network (radio access network, RAN) and a Core Network (CN), and the user equipment UE communicates with a Data Network (DN) through an access network device (e.g., a base station) and the core network.

A base station may be a device that communicates with user equipment, UE, and may provide communication coverage for a particular geographic area and may communicate with user equipment located within that coverage area (cell). A base station may communicate with any number of user devices. There may be multiple air interface connections between the base station and the user equipment, for example, there may be two air interface connections between the base station and the user equipment for transmitting data stream a and data stream B, respectively.

The core network may include: user plane function (user plane function, UPF) network elements, access and mobility management function (access and mobility management function, AMF) network elements, session management function (session management function, SMF) network elements, authentication server function (authentication server function, AUSF) network elements, network storage function (network repository function, NRF) network elements, unified data management (unified data management, UDM) network elements, policy control function (policy control function, PCF) network elements, network opening function (network exposure function, NEF) network elements, and application function (application function, AF) network elements.

The AF network element is configured to communicate a requirement of an application side to a network side, for example, a quality of service (quality of service, qoS) requirement, and the like. The AF network element may be a third-party functional network element, or may be an application service deployed by an operator, such as: IP multimedia subsystem (IP multimedia subsystem, IMS) voice call services.

PCF network elements are used for policy control, for example: and carrying out policy control such as charging, qoS, mobility and the like aiming at the session and the service flow level. The SMF network element is used for session management, for example: session management, PCF issuing control policy execution, UPF selection, UEIP address allocation, etc. AMF network elements for access and mobility management, e.g.: and performing mobility management, access authentication, authorization and other functions. UPF network elements for user plane data processing, such as: as the interface of the data network, the functions of user plane data forwarding, charging statistics based on session/stream level, bandwidth limitation and the like are completed. The NEF network element is used for exposing the capability of each network element to other network elements and providing corresponding security assurance to ensure the security of an external application network. NRF network elements for supporting service discovery functions, such as: and receiving a request sent by the network element, and then providing the discovered network element information to a requester, and maintaining the characteristics of the available network elements and the service capability supported by the available network elements. UDM network element for unified data management, for example: generating authentication certificates/authentication parameters, storing and managing permanent user identities of the 5G system, etc. AUSF network element for authentication server, for example: authentication of access is supported.

As shown in fig. 2, the user equipment accesses to the 5G network through the radio access network, and the RAN equipment (e.g., a base station) communicates with the AMF network element through an N2 interface (abbreviated as N2); RAN equipment (e.g., a base station) communicates with the UPF network element through an N3 interface (abbreviated as N3); the SMF network element communicates with the UPF network element through an N4 interface (N4 for short); the UPF network element accesses the data network through an N6 interface (N6 for short).

The related functional descriptions and interface descriptions may refer to the 5G system architecture (5G system architecture) in the 23501 standard, and are not described herein.

It will be appreciated that in the 5G network architecture shown in fig. 2, the functions of the network elements are merely exemplary, and that not all of the functions of the network elements are necessary when applied in embodiments of the present invention.

Currently, the 5G network is commercially available on a large scale worldwide, so that the base stations for deploying the 5G network are more and more, the network scale is continuously expanded, and the coverage range is gradually increased. Therefore, the evaluation and optimization work for 5G networks also needs to be developed synchronously. In an index system for evaluating the quality of a wireless network, the most intuitive index for reflecting the quality of the network is the rate experienced by a user.

The 5G network application scenes are diversified, and different application scenes have different demands on the network. Wherein, the differentiated service can be realized by slicing and other technologies on the core network side. For the radio access network side, differentiated services are mainly realized by depending on service scheduling of different 5G service quality identifiers (5 QIs), namely different 5 QIs are configured for transmission data of different service types. Therefore, it is very necessary to count the user perceived rate at granularity of distinguishing 5QI.

Typically, statistics of perceived rate and monitoring of common cell granularity (i.e., a summary of indicators that do not distinguish 5QI statistics) during data transmission between a base station and a user equipment. The data transmission between the base station and the user equipment can be divided into two cases of uplink data transmission and downlink data transmission, wherein the uplink data transmission is to transmit data from the user equipment to the base station, and the downlink data transmission is to transmit data from the base station to the user equipment. In downlink data transmission, the calculation of the user perception rate of the transmission data of different service types can distinguish 5QI for statistics. However, in uplink data transmission, due to the limitation of 3GPP protocol, the calculation of user perceived rate of transmission data of different service types cannot distinguish 5QI for statistics, for the following reasons: according to the 3GPP protocol, the user perceived rate calculation formula is as follows:

As can be seen from the above formula, differentiating 5QI calculates the user perceived rate in uplink data transmission, and three indexes for differentiating 5QI statistics need to be obtained: the method comprises the steps of transmitting data total amount in uplink data transmission, data amount of last slot in uplink data transmission, and transmission time length after removing the last slot in uplink data transmission, wherein the last slot in uplink data transmission is also called tail packet data amount in uplink data transmission, namely data amount of last slot in which a data buffer in uplink data transmission is empty is limited by the index that a base station algorithm cannot distinguish 5QI because the data buffer in uplink data transmission of a user is positioned in the user equipment and used for storing data amount to be transmitted, and the data amount to be transmitted is dynamically changed according to scheduling conditions of each time slot. The data Buffer to be transmitted in the uplink data transmission is that the user equipment reports a Buffer status report (Buffer status report, BSR) to the base station through a media access control layer (media access control, MAC layer), and the base station confirms the data to be transmitted of the user equipment according to the data content in the Buffer status report BSR, wherein the data to be transmitted of the user equipment is marked as Buffer Size in the embodiment of the present invention.

In order to reduce the number of information bits for the ue to transmit data in the air interface, the 3GPP protocol does not bind one buffer status report BSR for each logical channel, but reports the buffer status report BSR to the base station in units of logical channel groups (logical channel group, LCG). Each logical channel group comprises a plurality of logical channels, each logical channel can bear transmission data of a service type of 5QI, and the detailed corresponding relation is configured by the base station. Typically, the user equipment reports the buffer status report BSR to the base station through a buffer status report MAC control element (BSR MAC control element) of the MAC layer. The buffer status report BSR may generally take two formats: the first format is a short Buffer status report BSR, which is shown in fig. 3 and consists of one byte (Oct 1) (wherein one byte represents 8 bits), including an LCG Identification (ID) of data to be transmitted (LCGID shown in fig. 3), and an amount of data to be transmitted indicated by the LCGID (BS information shown in fig. 3, wherein the BS information is Buffer Size); the second format is a long Buffer status report BSR, as shown in fig. 4, where the long Buffer status report BSR is composed of 3 bytes (i.e., oct1, oct2, oct 3), and in this long Buffer status report BSR, the field for sending the data Size Buffer Size to be transmitted of each LCGID is fixed, so after receiving the long Buffer status report BSR, the base station may learn, through the value on the field corresponding to each LCG ID, that the data Size Buffer Size to be transmitted of each LCG ID of the user equipment, for example, BS information #0 is the data Size Buffer Size to be transmitted of LCG id=0, BS information #1 is the data Size Buffer Size to be transmitted of LCG id=1, BS information #2 is the data Size Buffer Size to be transmitted of LCG id=2, and BS information #3 is the data Size Buffer Size to be transmitted of LCG id=3.

Fig. 5 is a schematic diagram of a BSR according to an embodiment of the present invention. As shown in fig. 5, in the 5G communication system, the logical channels may be divided into 8 logical channel groups LCGs, and taking the buffer status report BSR shown in fig. 5 as an example, the first byte (Oct 1) of the buffer status report BSR indicates, by a bitmap (bitmap), LCG IDs of all data to be transmitted on the ue. Wherein one bit in the bitmap corresponds to one LCG ID. In the bitmap, each bit may be sequentially corresponding to one LCG ID in order of the LCG ID from small to large. Shown in fig. 5 is a schematic diagram of a buffer status report BSR in which each bit corresponds to one LCG ID in order of the LCG ID from small to large. And when the bit is a first value, indicating that the LCG ID corresponding to the bit is the LCG ID of the data to be transmitted, and when the bit is a second value, indicating that the LCG ID corresponding to the bit is the LCG ID of the data to be transmitted. Illustratively, the second value may be 0 when the first value is 1, or may be 1 when the first value is 0. A subsequent byte following the first byte (Oct 1) of the buffer status report BSR is used to indicate the amount of data to be transmitted of the LCG ID of the data to be transmitted indicated by the first byte. Wherein one byte is used to indicate the Buffer Size (i.e., BS information) of the data to be transmitted of the LCG ID of the data to be transmitted. The data amounts to be transmitted of the LCG IDs of the respective data to be transmitted may be sequentially arranged according to the order of the respective LCG IDs in the bitmap. Taking the first value of 1 and the second value of 0 as an example, assuming that each of the 8 LCGs shown in fig. 5 has data to be transmitted, oct1 may be 11111111.Oct2 is the data amount Buffer Size to be transmitted with LCG id=0, oct3 is the data amount Buffer Size to be transmitted with LCG id=1, oct4 is the data amount Buffer Size to be transmitted with LCG id=2, and so on.

At present, under the scene of the enhanced mobile broadband (enhanced mobile broadband, eMBB) with the widest application range, the common value of 5QI is 1-9 nine values (the maximum value can be expanded to 256 values), and different 5 QIs correspond to different service types. However, the available logical channel group LCG allocated by the base station to each ue is 8 groups at most, so the base station cannot separately configure one logical channel group LCG for each 5QI to report the amount of data to be transmitted.

The following three logical channel groups of eMBB and 5QI are commonly configured: firstly, if the logic channel group is not configured with 5QI, calculating the user perception rate of the transmission data of different service types does not need to distinguish 5QI for statistics; secondly, only one 5QI is configured in one logic channel group, and the calculation of the user perception rate of the transmission data of different service types can be counted by the 5 QI; third, one logical channel group is configured with two or more 5QI, and the calculation of the user perception rate of the transmission data of different service types cannot distinguish the 5QI for statistics.

The embodiment of the invention mainly focuses on the third situation, how to realize the calculation of the user perception rate of the transmission data of different service types to distinguish 5QI for statistics. To this end, an embodiment of the present invention provides a data transmission method.

The following describes various embodiments of the present invention with respect to an eMBB scenario in which a base station configures 8 logical channel groups for each ue and 5QI takes nine values, 1-9, as examples. The 5QI configured by the base station for the 8 logical channel groups is shown in table 1 below:

TABLE 1

Meanwhile, the base station sets an array VolLstPac with a length of 9 as a counter for distinguishing the data amount to be transmitted in the uplink data transmission of 5QI for each user equipment, and the counter is reset to zero after each data transmission is completed. By using

Representing user equipment UE _i In a data transmission process, the data quantity to be transmitted of transmission data with 5QI as j, and the value of j is 1 to 9. By Buffer Size _{LCG ID＝k} Indicating the current logical channel group identity LCG ID is k the amount of data Buffer Size to be transmitted. When the base station receives the user equipment UE _i And updating the counter by association backfilling when the buffer status report BSR.

In the first case, the logical channel group in the buffer status report BSR is not configured with 5QI, referring to table 1. For example, when the base station receives LCG id=0 or LCG id=1 or LCG id=3 in the buffer status report BSR, since the 5QI corresponding to the logical channel group is null,

And (5) keeping the initial state without updating.

In case two, a logical channel group in the buffer status report BSR is configured with one 5QI, referring to table 1 above. For example, when the base station receives LCG id=2 or LCG id=4 or LCG id=6 in the buffer status report BSR, since each logical channel group corresponds to one 5QI, the base station updates the buffer status report according to the following rule

When LCG id=2, the buffer status report BSR reports the amount of data to be transmitted of transmission data of 5 qi=5.

When LCG id=4, the buffer status report BSR reports the amount of data to be transmitted of transmission data of 5 qi=1.

When LCG id=6, the buffer status report BSR reports a transmission number of 5 qi=7According to the amount of data to be transmitted.

In the above two cases, the problem that the calculation of the user perceived rate of the transmission data of different service types cannot distinguish 5QI for statistics is not considered in the embodiments of the present invention.

Then referring to table 1, in the third case, when LCG id=7 in the buffer status report BSR received by the base station, the base station reports the data volume to be transmitted of the transmission data of three service types, i.e. 5QI is 6,8, and 9, simultaneously in one logical channel group, and the base station cannot distinguish which service type corresponding to the transmission data of the current data volume to be transmitted and which service type corresponding to the service type is 6,8, and 9, so that the calculation of the user perception rate of the transmission data of different service types cannot distinguish the 5QI for statistics.

To solve the above-mentioned problem in the third case, an embodiment of the present invention provides a data transmission method, and referring to a flowchart of a data transmission method shown in fig. 6, a data transmission method provided by an embodiment of the present invention will be described in detail below with reference to fig. 6.

201. And the base station receives a Buffer Status Report (BSR) sent by the user equipment.

Wherein, the buffer status report BSR includes: the target user identity of the radio access network (for example, may be a cell-radio network temporary identifier, C-RNTI), the logical channel group identity LCG ID corresponding to the target user identity, and the Buffer Size of the logical channel group indicated by the logical channel group identity, refer to the data structure of the Buffer status report BSR shown in table 2. When different user equipment sends a Buffer Status Report (BSR), the different user equipment has own special C-RNTI, the C-RNTI uniquely identifies the user equipment under the air interface of a cell, only the user equipment under the connection state is valid for the corresponding C-RNTI, and when the user equipment reports the BSR through a Buffer status report (MAC) control element (BSR MAC control element) of an MAC layer, the user equipment all comprises the current target user identification, a logic channel group identification (LCG ID) corresponding to the target user identification and the data quantity Buffer Size to be transmitted of the logic channel group indicated by the logic channel group identification.

202. The base station obtains data of an operation domain of the radio access network.

Wherein, the data of the operation domain of the radio access network is operation support system (operation support system, abbreviated as O domain) data, wherein the data of the operation domain of the radio access network is operation state monitoring of equipment (such as user equipment and base station) of the radio access network by using a radio operation maintenance center (operation and maintenance center-radio, OMC-R), such as OMC-R shown in fig. 2, acquires the data of the O domain including signaling and trace (trace) data, and the OMC-R is connected to the radio access network through a file interface.

203. And the base station acquires the user temporary identifier corresponding to the target user identifier in the core network and the 5QI corresponding to the user temporary identifier from the data of the operation domain of the wireless access network.

Specifically, in step 203, the base station acquires a radio resource control RRC (radio resource control, RRC) setup request message ticket in data of an operation domain of the radio access network. Wherein the RRC establishment request message occurs when the user equipment is in idle mode, the user equipment will initiate an RRC connection establishment request procedure if the non-access stratum (non access stratum, NAS) of the user equipment requests to establish a signaling connection. For example, the RRC establishment request message ticket may be obtained from the trace data, and table 3 shows a data structure of the RRC establishment request message ticket, including: the target user identity of the radio access network (which may be, for example, a cell-radio network temporary identifi er, C-RNTI)), the user temporary identity of the core network (which may be, for example, a Next Generation (NG) interface application layer protocol identity (AMF UE NG appl ication protocol ID) between the access and mobility management function AMF and the user equipment UE, AMF UE NGAP ID).

TABLE 3 Table 3

In addition, the base station needs to acquire an initial context configuration request message ticket (INITIAL CONTEXT SETUP REQUEST) or a protocol data unit session resource configuration request message ticket (PDU SESSION RESOURCE SETUP REQUEST) from the data of the operation domain of the radio access network. For example, an initial context configuration request message ticket or a protocol data unit session resource configuration request message ticket may be obtained from the trace data, where the AMF sends the initial context configuration request message to the base station in order to initiate the initial context setup procedure; to establish a protocol data unit (protocol data unit, PDU) session, the AMF sends a protocol data unit session resource configuration request message to the base station. And the initial context configuration request message or the protocol data unit session resource configuration request message carries information such as quality attribute (i.e. 5 QI) of the QoS flow. That is, the data structure of the initial context configuration request message ticket or protocol data unit session resource configuration request message ticket as shown in table 4 contains both a user temporary identity (e.g., AMF UE NGAP ID) and 5QI.

AMF UE NGAP ID

TABLE 4 Table 4

And then, the base station acquires the user temporary identifier corresponding to the target user identifier in the core network from the Radio Resource Control (RRC) establishment request message ticket according to the target user identifier. The AMF UE NGAP ID is obtained in Table 3 based on the C-RNTI in Table 2. And the base station acquires the 5QI corresponding to the user temporary identifier from the initial context configuration request message ticket or the protocol data unit session resource configuration request message ticket according to the user temporary identifier. That is, 5QI is obtained in Table 4 based on AMF UE NGAP ID in Table 3.

204. The base station associates 5QI with the target user identity.

For the present configuration, the base station receives LCG id=7 in the buffer status report BSR, and reports the data volume to be transmitted of the transmission data of three service types, i.e. 6,8 and 9, of 5QI in one logical channel group at the same time. And 5QI is 6,8,9 are default bearers, wherein 5 qi=9 is a default bearer of a common user, 5 qi=8 is a default bearer of a guest (very important person, VIP) user, and 5 qi=6 is a default bearer of a super member (super very important person, SVIP) user, so that only one of 5QI of 6,8,9 exists for each user to initially establish a connection. So that the user temporary identifier corresponding to the current target user identifier in the core network and the 5QI corresponding to the user temporary identifier can be queried. Referring to table 5, the BSR, RRC, and the common data structure in the initial context configuration request message ticket or the protocol data unit session resource configuration request message ticket are associated to obtain a new data structure as shown in table 5 below, so that 5QI can be associated with the target user identity.

Finally, the counter distinguishing the data amount to be transmitted in the uplink data transmission of 5QI can also be updated after the association is completed.

I.e. a logarithmic group based on the target user identity and 5QI as described above

The updating is performed according to the following principle. />

Backfilling 5 qi=6 after data association, and reporting the buffer status report BSR by the amount of data to be transmitted of the transmission data of 5 qi=6.

Backfilling 5 qi=8 after data association, and reporting the buffer status report BSR by the amount of data to be transmitted of the transmission data of 5 qi=8.

Backfilling 5 qi=9 after data association, and reporting the buffer status report BSR by the amount of data to be transmitted of the transmission data of 5 qi=9.

In the above-mentioned data transmission method with the LCG ID of 7 in the third case, the logical channel group with the LCG ID of 7 simultaneously reports the data volume to be transmitted of the transmission data with the three service types of 5QI of 6,8 and 9, because the base station obtains the target user identifier of the radio access network, the logical channel group identifier LCG ID corresponding to the target user identifier, and the data volume Buffer Size of the logical channel group indicated by the logical channel group identifier from the Buffer status report BSR, and obtains the radio resource control RRC establishment request message ticket from the data of the operation domain of the radio access network, the radio resource control RRC establishment request message ticket includes the target user identifier and the user temporary identifier, and then obtains the initial context configuration request message ticket (or protocol data unit session resource configuration request message ticket) from the data of the operation domain of the radio access network, where the initial context configuration request message ticket (or protocol data unit session resource configuration request message ticket) includes the user temporary identifier and the 5QI, and the base station can associate the 5QI with the target user identifier according to the currently obtained data. Specific examples are: 5 qi=9 is the default bearer of the normal user, 5 qi=8 is the default bearer of the VIP user, and 5 qi=6 is the default bearer of the SVIP user. Since each user initially establishes a connection and only has one service type of 5QI of 6,8 and 9, if the current 5 qi=9, the buffer status report BSR reports the data quantity to be transmitted of the transmission data of the service of the common user of 5 qi=9; if the current 5 QI=8, reporting the data quantity to be transmitted of the transmission data of the service of the VIP user with the 5 QI=8 by the buffer status report BSR; if the current 5 qi=6, the buffer status report BSR reports the amount of data to be transmitted of the transmission data of the service of the SVIP user with 5 qi=6. The method solves the problem that the calculation of the user perception rate of the transmission data of different service types can not distinguish 5QI for statistics.

In this way, in the above scheme, since the user equipment sends the BSR including the target user identifier of the radio access network, the logical channel group identifier corresponding to the target user identifier, and the data amount to be transmitted of the logical channel group indicated by the logical channel group identifier to the base station, the base station may further acquire the data including the user temporary identifier corresponding to the target user identifier in the core network and the operation domain of the radio access network of 5QI corresponding to the user temporary identifier. The data of the operation domain of the wireless access network comprises the corresponding relation between the target user identifier of the wireless access network and the user temporary identifier of the core network and also comprises the corresponding relation between the user temporary identifier and the 5QI, so that the base station can correlate the target user identifier of the wireless access network in the BSR with the 5QI in a data backfilling mode, thereby determining the corresponding relation between the 5QI and the data quantity to be transmitted of a logical channel group corresponding to the logical channel group identifier of uplink transmission data, and further solving the problem that the calculation of the user perception rate of the transmission data of different service types cannot distinguish the 5QI for statistics.

To distinguish the calculation of the user perceived rate of the transmitted data at different times from 5QI, statistics are made. The data transmission method provided by the embodiment of the invention further comprises time verification. Specifically, after step 203, that is, after the BSR, the RRC establishment request message ticket, and the initial context configuration request message ticket or the protocol data unit session resource configuration request message ticket are acquired, the timestamps contained in the BSR, the RRC establishment request message ticket, or the initial context configuration request message ticket need to be matched. Specifically, the buffer status report BSR includes a first timestamp, as shown in table 2, where the first timestamp is a time when the base station receives the buffer status report BSR; the Radio Resource Control (RRC) establishment request message ticket comprises a second timestamp, as shown in table 3, wherein the second timestamp is the time when the base station receives the RRC establishment request message; the initial context configuration request message ticket includes a third timestamp, e.g., a third timestamp shown in table 4, where the third timestamp is a time when the base station receives the initial context configuration request message ticket, or the protocol data unit session resource configuration request message ticket includes a third timestamp, e.g., a third timestamp shown in table 4, where the third timestamp is a time when the base station receives the protocol data unit session resource configuration request message ticket. Step 204 is performed again when the base station determines that the first time stamp is later than the third time stamp and the third time stamp is later than the second time stamp. As shown in table 5, the first timestamp is also associated to the data structure, and because the first timestamp represents the time when the base station receives the current Buffer status report BSR, the Buffer status report BSR includes the target user identifier of the radio access network, the logical channel group identifier LCG ID corresponding to the target user identifier, and the to-be-transmitted data Size Buffer Size of the logical channel group indicated by the logical channel group identifier, and the current first timestamp is added, it is possible to implement the calculation of the user perception rate of the transmission data at different times to distinguish 5QI for statistics.

In the fourth case, when the base station receives LCG id=5 in the buffer status report BSR, the base station reports the data amount to be transmitted of the transmission data of three service types, i.e. 2,3, and 4, in one logical channel group, and the base station cannot distinguish which service type the transmission data of the current data amount to be transmitted corresponds to and which service type the 5QI corresponding to the service type is 2,3, and 4, so that the calculation of the user perception rate of the transmission data of different service types cannot distinguish the 5QI for statistics.

In order to solve the problem in the fourth case, an embodiment of the present invention provides another data transmission method, and referring to fig. 7, another data transmission method provided by the embodiment of the present invention will be described in detail with reference to fig. 7.

301. And the base station receives a Buffer Status Report (BSR) sent by the user equipment.

302. The base station obtains data of an operation domain of the radio access network.

303. The base station acquires data of an operation domain of the core network.

Wherein, the data of the operation domain of the core network is the data of the operation support system (operation support system, O domain for short); the data of the operation domain of the core network is that a core operation maintenance center (operation and maintenance center-core, OMC-C) is used to monitor the working state of the equipment of the core network, such as OMC-C shown in fig. 2, wherein the OMC-C is connected to the radio access network through a deep packet inspection (deep packet inspection, DPI) interface.

304. And the base station acquires the user temporary identifier corresponding to the target user identifier in the core network from the data of the operation domain of the wireless access network.

Specifically, in step 304, the base station acquires a radio resource control RRC establishment request message ticket from data of an operation domain of the radio access network. Wherein the RRC establishment request message occurs when the user equipment is in idle mode, and if the non-access stratum (non access stratum, NAS) of the user equipment requests to establish the signaling connection, the user equipment will initiate an RRC connection establishment request procedure. For example, the RRC establishment request message ticket may be obtained from the trace data, and table 3 shows a data structure of the RRC establishment request message ticket, including: the target user identity of the radio access network (which may be, for example, a cell-radio network temporary identifier, C-RNTI)), the user temporary identity of the core network (which may be, for example, a Next Generation (NG) interface application layer protocol identity (AMF UE NG application protocol ID) between the access and mobility management function AMF and the user equipment UE, AMF UE NGAP ID).

And the base station acquires the user temporary identifier corresponding to the target user identifier in the core network from the radio resource control RRC establishment request message ticket according to the target user identifier. The AMF UE NGAP ID is obtained in Table 3 based on the C-RNTI in Table 2.

305. The base station acquires the user ticket type corresponding to the user temporary identifier from the data of the operation domain of the core network, wherein the user ticket type corresponds to 5QI one by one.

Specifically, in step 305, the base station first obtains certain detailed record (x detailed record, xDR) data from the data of the operation domain of the core network. Where xDR may be a detailed record of voice call traffic (call detai led record, CDR) or transaction detailed record (transaction detailed record, TDR) or a detailed record of TCP/IP (transmission control protocol/internet protocol) communications (TCP/IP detailed record, IPDR) or the like. Wherein the data structure of the xDR shown in table 6 is referred to, and the xDR data includes a start time of the xDR, an end time of the xDR, a user permanent identifier (subscr iption permanent identifier, SUPI), a user temporary identifier (for example, may be an AMF UE NGAP ID), and a user ticket type.

Start time

End time

AMF UE NGAP ID

User ticket type

TABLE 6

And then the base station acquires the user ticket type corresponding to the user temporary identifier from the xDR data according to the user temporary identifier. The user ticket type is obtained in table 6 based on the AMF UE NGAP ID in table 3.

306. The base station associates the user ticket type with the target user identification.

The user ticket type is used for representing the service type of the user in the ticket data, the user ticket type can take the following numerical values, wherein the user ticket type value is 1 for representing hypertext transfer protocol (hyper text transfer protocol, HTTP) service, the user ticket type value is 2 for representing hypertext transfer security protocol (hyper text transfer protocol over secure socket layer, HTTPs) service, the user ticket type value is 3 for representing domain name system (domain name system, DNS) service, the user ticket type value is 4 for representing other services, the user ticket type value is 5 for representing instant messaging (instant messaging, IM) service, the user ticket type value is 6 for representing video type statistics service, and the user ticket type value is 7 for representing game statistics service.

For the present configuration, when LCG id=5, the data volume to be transmitted of the transmission data of the three service types of 5QI being 2,3, and 4 is reported in one logical channel group, and the data of the three service types is not simultaneously transmitted by the same ue, where 5 qi=2 carries a voice over-term evolution (voice) service, 5 qi=3 carries a game service, and 5 qi=4 carries a video service. Therefore, when the user ticket type is game service, the 5QI at the moment can be determined to be 3; when the user ticket type is video service, the 5QI at the moment can be determined to be 4; when the user ticket type is empty and the Buffer Size of the data to be transmitted of the current logical channel group is not equal to 0, it may be determined that the 5QI at this time is 2. The above can prove that the user ticket types are in one-to-one correspondence with 5 QI.

Referring to table 7, the common data structures in BSR, RRC and xDR are associated to obtain a new data structure as shown in table 7 below, so that the user ticket type can be associated with the target user identity.

TABLE 7

Finally, the counter for distinguishing the data quantity to be transmitted in the uplink data transmission of 5QI can also be updated after the association is completed.

The pair of numbers is based on the current user ticket type and the target user identification

The updating is performed according to the following principle.

When the user ticket type is null and Buffer Size _{LCG ID＝5} When not equal to 0, the buffer status report BSR reports the amount of data to be transmitted of the transmission data of 5 qi=2.

When the user ticket type is game service, the buffer status report BSR reports the data quantity to be transmitted of the transmission data of 5 qi=3.

When the user ticket type is video service, the buffer status report BSR reports the data quantity to be transmitted of the transmission data of 5 qi=4.

In the above another data transmission method with the LCG ID of 5 in the fourth case, the logical channel group with the LCG ID of 5 simultaneously reports the data volume to be transmitted of the transmission data of three service types, i.e. 5QI is 2,3, and 4, because the base station obtains the target user identifier of the radio access network, the logical channel group identifier LCG ID corresponding to the target user identifier, and the data volume Buffer Size of the logical channel group indicated by the logical channel group identifier from the Buffer status report BSR, and obtains the radio resource control RRC establishment request message ticket from the data of the operation domain of the radio access network, the radio resource control RRC establishment request message ticket includes the target user identifier and the user temporary identifier, and then obtains xDR data from the data of the operation domain of the core network, where the xDR data includes the user temporary identifier and the user ticket type, and the user ticket type are in one-to-one correspondence, and the base station can associate the user ticket type with the target user identifier according to the currently obtained data, that is, and the base station associates the 5QI with the target user identifier. Specific examples are: 5 qi=2 carries Volte traffic, 5 qi=3 carries game-like traffic, and 5 qi=4 carries video-like traffic. Because the same user equipment does not send the data of the three service types at the same time, when the user ticket type is empty and the current Buffer Size of the data to be transmitted is not equal to 0, the data to be transmitted of the transmission data of the Volte service with the priority of 5 QI=2, which is reported by the Buffer status report BSR, can be determined; when the user ticket type is game service, determining the data quantity to be transmitted of the transmission data of the game service with 5 QI=3 reported by the buffer status report BSR; when the user ticket type is video service, the data volume to be transmitted of the transmission data of the video service with 5 QI=4 reported by the buffer status report BSR can be determined. The method solves the problem that the calculation of the user perception rate of the transmission data of different service types can not distinguish 5QI for statistics.

In this way, in the above scheme, the user equipment sends the BSR including the target user identifier of the radio access network, the logical channel group identifier corresponding to the target user identifier, and the data amount to be transmitted of the logical channel group indicated by the logical channel group identifier to the base station, and the base station may further obtain the data of the operation domain of the radio access network including the target user identifier corresponding to the user temporary identifier of the core network and the data of the operation domain of the core network including the user ticket type corresponding to the user temporary identifier, where the data of the operation domain of the radio access network includes the correspondence between the target user identifier of the radio access network and the user temporary identifier of the core network, and the data of the operation domain of the core network includes the correspondence between the user temporary identifier and the user ticket type, and the user ticket type corresponds to 5QI one by one.

To distinguish the calculation of the user perceived rate of the transmitted data at different times from 5QI, statistics are made. The data transmission method provided by the embodiment of the invention further comprises time verification. Specifically, after step 305, that is to say after the BSR, the RRC setup request message, and the xDR data are acquired, the timestamps contained therein need to be matched. Specifically, the buffer status report BSR includes a first timestamp, that is, a first timestamp in table 2, where the first timestamp is a time when the base station receives the buffer status report BSR; the radio resource control RRC establishment request message ticket includes a second timestamp, that is, a second timestamp in table 3, where the second timestamp is a time when the base station receives the radio resource control RRC establishment request message; the xDR data contains a third timestamp, i.e. the end time in table 6, wherein the third timestamp is the end time of the statistical xDR message. After the base station determines that the first time stamp is later than the second time stamp and that both the first time stamp and the second time stamp are earlier than the third time stamp, step 306 is performed. As shown in table 7, the first timestamp is associated to the data structure, and because the first timestamp represents the time when the base station receives the current Buffer status report BSR, the Buffer status report BSR includes the target user identifier of the radio access network, the logical channel group identifier LCG ID corresponding to the target user identifier, and the to-be-transmitted data Size Buffer Size of the logical channel group indicated by the logical channel group identifier, and the current first timestamp is added, it is possible to implement the statistics of the user perception rate calculation of the transmission data at different times by differentiating 5 QI.

So far, in combination with the situation that the base station is configured with 5 QIs in 8 logical channel groups, the data transmission method provided by the embodiment of the invention can realize that the calculation of the user perception rate of the transmission data of different service types can distinguish the 5 QIs for statistics in the uplink data transmission process. Of course, the above-mentioned data transmission method may also be applied to the case where other types of logical channel groups are configured with different 5QI, and the embodiment of the present invention does not limit which logical channel group is configured with what 5 QI.

An embodiment of the present invention also provides a base station, fig. 8 shows a schematic base station structure with a data transmission method provided by the embodiment of the present invention, as shown in fig. 8, the base station 40 includes: a receiving unit 401, an acquiring unit 402, and a processing unit 403.

A receiving unit 401, configured to receive a buffer status report BSR sent by a user equipment, where the buffer status report BSR includes: the method comprises the steps of target user identification of a wireless access network, a logic channel group identification corresponding to the target user identification and data quantity to be transmitted of a logic channel group indicated by the logic channel group identification.

An acquiring unit 402, configured to acquire data of an operation domain of the radio access network.
