Background

A fifth generation mobile communication technology (5G) network is in large-scale commercial use in the global scope, and more base stations for deploying and applying the 5G network are provided, the network scale is continuously expanded, and the coverage range is gradually increased. Therefore, the evaluation and optimization work for 5G networks also requires a synchronous development. In an index system for evaluating the quality of a wireless network, the most intuitive index reflecting the network quality is the rate experienced by a user.

The application scenes of the 5G network are diversified, and the requirements of different application scenes on the network are different. Wherein, differentiated services can be realized through technologies such as slicing and the like at the core network side. For the radio access network side, differentiated services are mainly implemented by depending on service scheduling of different 5G quality of service identifiers (5 QI), that is, different 5QI are configured for transmission data of different service types. Therefore, it is very necessary to count the user perceived rate with granularity to distinguish 5 QI. Currently, in the downlink data transmission process, the calculation of the user perception rates of the transmission data of different service types can distinguish 5QI for statistics. However, in the uplink data transmission process, the calculation of the user perceived rate of the transmission data of different service types cannot distinguish 5QI for statistics due to the limitation of the third generation partnership project (3 GPP) protocol.

For convenience of description, the access network device 120 in the embodiment of the present invention is described by taking a base station as an example.

In the embodiment of the present invention, the description is mainly 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 (RAN) and a Core Network (CN), and the 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 are two air interface connections between the base station and the user equipment, which are used to transmit data stream a and data stream B, respectively.

The core network may include: a User Plane Function (UPF) network element, an access and mobility management function (AMF) network element, a Session Management Function (SMF) network element, an authentication server function (AUSF) network element, a network storage function (NRF) network element, a Unified Data Management (UDM) network element, a Policy Control Function (PCF) network element, a network open function (NEF) network element, and an Application Function (AF) network element.

The AF network element is used to transfer requirements of the application side on the network side, such as quality of service (QoS) requirements. 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 (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 conversation and the service flow level. SMF network elements are used for session management, for example: and performing session management, PCF (point to point) issuing control strategies, UPF (user equipment) selection, UEIP (user equipment) address allocation and the like. AMF network elements for access and mobility management, such as: and performing functions of mobility management, access authentication, authorization and the like. A UPF network element, configured to process user plane data, for example: as the interface of the data network, the functions of user plane data forwarding, session/flow level based charging statistics, bandwidth limitation and the like are completed. The NEF network elements are used for exposing the capability of each network element to other network elements and providing corresponding security guarantee to ensure the security of the 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 requesting party to maintain the characteristics of the available network elements and the service capability supported by the available network elements. UDM network elements for unified data management, such as: generating authentication certificates/parameters, storing and managing permanent user identities of the 5G system, etc. AUSF network element for an authentication server, for example: and the authentication of the access is supported.

As shown in fig. 2, the user equipment accesses 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 (referred to as N2); RAN equipment (e.g., base stations) communicate with the UPF network elements over an N3 interface (abbreviated 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 description of related functions and interfaces can refer to the 5G system architecture (5G system architecture) diagram in the 23501 standard, which is not repeated herein.

It is to be understood that in the 5G network architecture shown in fig. 2, the functions of the network elements are only exemplary, and not all the functions of the network elements are necessary when the network elements are applied to the embodiment of the present invention.

At present, the 5G network is widely used in a commercial scale around the world, and more base stations are used for deploying the 5G network, the network scale is continuously expanded, and the coverage range is gradually increased. Therefore, the evaluation and optimization work for 5G networks also requires a synchronous development. In an index system for evaluating the quality of a wireless network, the most intuitive index reflecting the network quality is the rate experienced by a user.

The application scenes of the 5G network are diversified, and the requirements of different application scenes on the network are different. Wherein, differentiated services can be realized through technologies such as slicing and the like at the core network side. For the radio access network side, differentiated services are mainly realized by depending on service scheduling of different 5G quality of service identifiers 5QI, i.e. different 5QI are configured for transmission data of different service types. Therefore, it is very necessary to count the user perceived rate with granularity to distinguish 5 QI.

In general, the statistics of the perceived rate and the monitoring of the cell granularity are often used during data transmission between the base station and the user equipment (i.e. the aggregated value of the indicators without distinguishing the 5QI statistics). Data transmission between the base station and the user equipment can be divided into two cases, namely uplink data transmission and downlink data transmission, wherein the uplink data transmission is data transmission from the user equipment to the base station, and the downlink data transmission is data transmission from the base station to the user equipment. In the 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 perception rates 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, distinguishing the user perception rate in the uplink data transmission of the 5QI computer requires acquiring three indexes for distinguishing the 5QI statistics: the total amount of transmission data in uplink data transmission, the data amount of the last slot transmission in the uplink data transmission, and the transmission duration after the last slot is removed in the uplink data transmission, wherein "the data amount of the last slot transmission in the uplink data transmission" is also called tail packet data amount in the uplink data transmission, that is, a data buffer in the uplink data transmission is the empty data amount of the last slot transmission in one data transmission by user equipment, and the index is limited by that a base station algorithm cannot distinguish 5QI, because the data buffer in the uplink data transmission of the user is located in the user equipment and is used for storing the data amount to be transmitted, and the data amount to be transmitted is dynamically changed according to the scheduling condition of each slot. The data volume to be transmitted in the data Buffer in uplink data transmission is that the user equipment reports a Buffer Status Report (BSR) of a Media Access Control (MAC) layer to the base station, and the base station determines the data volume to be transmitted of the user equipment according to the data content in the Buffer status report BSR, wherein the data volume 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 of data transmitted by the ue in the air interface, the 3GPP protocol does not bind a buffer status report BSR to each logical channel, but reports the buffer status report BSR to the base station in units of Logical Channel Groups (LCGs). Each logical channel group comprises a plurality of logical channels, each logical channel can bear transmission data of a 5QI service type, and the detailed corresponding relation is configured by the base station. Generally, a user equipment reports a Buffer Status Report (BSR) to a base station through a buffer status report MAC control element (BSR MAC control element) of a MAC layer. Generally, the buffer status report BSR may adopt two formats: the first format is a short Buffer status report BSR, which is composed of a byte (Oct1) (one byte represents 8 bits) as shown in fig. 3, and includes an LCG Identification (ID) of data to be transmitted (LCGID as shown in fig. 3), and an amount of data to be transmitted indicated by the LCGID (BS information as shown in fig. 3, where the BS information is Buffer Size); the second format is a long Buffer status report BSR, as shown in fig. 4, the long Buffer status report BSR is composed of 3 bytes (i.e., Oct1, Oct2, Oct3), and in the long Buffer status report BSR, a field used for sending the pending data Size Buffer of each LCGID is fixed, so that, after receiving the long Buffer status report BSR, the base station can obtain the pending data Size Buffer Size of each LCG ID of the ue through a value in the field corresponding to each LCG ID, for example, BS information #0 is the pending data Size Buffer Size with LCG ID ═ 0, BS information #1 is the pending data Size Buffer Size with LCG ID ═ 1, BS information #2 is the pending data Size Buffer Size with LCG ID ═ 2, and BS information #3 is the pending data Size Buffer Size with 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 a 5G communication system, 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 (Oct1) of the buffer status report BSR indicates all LCG IDs of data to be transmitted on the user equipment through a bitmap (bitmap). Wherein one bit in the bitmap corresponds to one LCG ID. In the bitmap, each bit may be sequentially associated with one LCG ID in the order of the smaller LCG ID to the larger LCG ID. Fig. 5 is a schematic diagram illustrating a buffer status report BSR in which each bit corresponds to one LCG ID in the descending order of the LCG IDs. 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 without the data to be transmitted. For example, 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 (Oct1) of the buffer status report BSR for indicating an amount of data to be transmitted of the LCG ID of the data to be transmitted indicated by the first byte. One byte is used to indicate the amount of data to be transmitted, Buffer Size (i.e., BS information) of an LCG ID of data to be transmitted. The data volumes to be transmitted of the LCG IDs of the data to be transmitted may be sequentially arranged according to the order of the LCG IDs in the bitmap. For example, assuming that the first value is 1 and the second value is 0, each of the 8 LCGs shown in fig. 5 has data to be transmitted, Oct1 may be 11111111. Oct2 is the data Size Buffer Size to be transmitted with the LCG ID being 0, Oct3 is the data Size Buffer Size to be transmitted with the LCG ID being 1, Oct4 is the data Size Buffer Size to be transmitted with the LCG ID being 2, and so on.

At present, in an enhanced mobile broadband (eMBB) scene with the widest application range, the common value of the 5QI is 1-9 nine values (which can be expanded to 256 values at most), and different 5 QIs correspond to different service types. However, the available LCGs allocated by the base station to each ue are up to 8 sets, so the base station cannot individually configure one LCG for each 5QI to report the amount of data to be transmitted.

The logical channel group of the eMBB and the 5QI general configuration have the following three types: firstly, if the logical channel group is not configured with 5QI, the calculation of the user perception rates of the transmission data of different service types does not need to distinguish 5QI for statistics; secondly, only one 5QI is configured in one logical 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; thirdly, two or more 5 QIs are allocated to one logical channel group, and the calculation of the user perception rates of the transmission data of different service types cannot distinguish the 5 QIs for statistics.

The embodiment of the present invention mainly focuses on the third situation, how to implement calculation of user perception rates of transmission data of different service types to distinguish 5QI for statistics. Therefore, the embodiment of the invention provides a data transmission method.

In the following, the embodiments of the present invention will be described by taking an example in which the base station configures 8 logical channel groups for each ue in an eMBB scenario, and 5QI takes nine values of 1 to 9. The base station configures 5QI for 8 logical channel groups as shown in table 1 below:

TABLE 1

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

Representing user equipment, UE_iIn one data transmission process, 5QI is the data volume to be transmitted of the transmission data of j, and the value of j is 1 to 9. Using Buffer Size_{LCG ID＝k}Is shown asThe front logical channel group identifies the amount of data Buffer Size to be transmitted with LCG ID of k. When the base station receives the user equipment UE_iThe buffer status report BSR of (1) updates the counter by associated backfilling.

Wherein, referring to table 1 above, in case one, the logical channel group in the buffer status report BSR is not configured with 5 QI. For example, when the base station receives the LCG ID of 0, LCG ID of 1, or LCG ID of 3 in the BSR, since the 5QI corresponding to the above logical channel group is empty,

not updated, and the initial state is kept.

Referring to table 1 above, in case two, the logical channel group in the buffer status report BSR is configured with one 5 QI. For example, when the base station receives the LCG ID of 2 or 4 or 6 in the BSR, since each of the above-mentioned logical channel groups corresponds to a 5QI, the procedure is updated according to the following rule

When the LCG ID is 2, the buffer status report BSR reports a pending transmission data amount of transmission data with 5QI being 5.

When the LCG ID is 4, the buffer status report BSR reports the pending transmission data amount of the transmission data with 5QI being 1.

When the LCG ID is 6, the buffer status report BSR reports the pending transmission data amount of the transmission data with 5QI being 7.

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

Referring to table 1, in case three, when the LCG ID in the buffer status report BSR received by the base station is 7, the to-be-transmitted data amount of the transmission data with three service types, i.e., 6,8 and 9, is reported simultaneously in one logical channel group, and the base station cannot distinguish the service type corresponding to the transmission data with the current to-be-transmitted data amount and which of the 6,8 and 9 the 5QI corresponding to the service type, so that the calculation of the user sensing rates of the transmission data with different service types cannot distinguish the 5QI for statistics.

To solve the problem in the third situation, 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 the buffer status report BSR sent by the user equipment.

Wherein the buffer status report BSR includes: a target user identifier (for example, a cell-radio network temporary identifier (C-RNTI)), a logical channel group identifier LCG ID corresponding to the target user identifier, and a to-be-transmitted data Size of a logical channel group indicated by the logical channel group identifier, of the radio access network 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 C-RNTI uniquely identifies the user equipment under a cell gap, and only the user equipment in a connection state has the corresponding C-RNTI valid, and when the user equipment reports the BSR through a Buffer status report (BSR MAC control element) of an MAC layer, the user equipment comprises a current target user identifier, a logical channel group identifier (LCG ID) corresponding to the target user identifier, and a to-be-transmitted data Size of a logical channel group indicated by the logical channel group identifier.

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

The data of the operation domain of the radio access network is operation support system (O domain for short) data, wherein the data of the operation domain of the radio access network is data of an O domain that uses a radio operation and maintenance center (OMC-R) to monitor the operating state of devices (such as user equipment and a base station) of the radio access network, such as the OMC-R shown in fig. 2, and obtains 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. The base station acquires a user temporary identifier corresponding to the target user identifier in a core network and a 5QI corresponding to the user temporary identifier from data of an operation domain of the wireless access network.

Specifically, in step 203, the base station acquires a Radio Resource Control (RRC) setup request message ticket from data in an operation domain of the radio access network. Wherein the RRC connection establishment request message occurs when the user equipment is in an idle mode, and if a Non Access Stratum (NAS) of the user equipment requests establishment of a signaling connection, the user equipment initiates an RRC connection establishment request procedure. Exemplarily, 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, which includes: a target user identity (e.g., a cell-radio network temporary identity (C-RNTI)) of the radio access network, a user temporary identity corresponding to the core network (e.g., a Next Generation (NG) interface application protocol identity (AMF UE NG application protocol ID) between the access and mobility management function AMF and the user equipment UE, and an AMF UE NGAP ID).

In addition, the base station needs to obtain 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 data in an operation domain of the radio access network. Exemplarily, an initial context configuration request message ticket or a protocol data unit session resource configuration request message ticket may be obtained in the trace data, where in order to start an initial context establishment process, the AMF sends the initial context configuration request message to the base station; to establish a Protocol Data Unit (PDU) session, the AMF sends a PDU session resource configuration request message to the base station. And the initial context configuration request message or the pdu session resource configuration request message carries information such as the quality attribute (i.e. 5QI) of the QoS flow. That is, the data structure of the initial context configuration request message ticket or the pdu session resource configuration request message ticket shown in table 4 includes the temporary user identifier (e.g., AMF UE NGAP ID) and 5 QI.

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

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

For the current configuration, the base station receives the LCG ID of 7 in the buffer status report BSR, and reports 5QI to be transmitted data amount of transmission data of three service types, 6,8, and 9, simultaneously in one logical channel group. And 5QI is 6,8, and 9 are default bearers, where 5QI ═ 9 is the default bearer of the normal user, 5QI ═ 8 is the default bearer of the honored guest (VIP) user, and 5QI ═ 6 is the default bearer of the super membership (SVIP) user, so that there is only one of 5QI 6,8, and 9 for each user to establish a connection for the first time. Therefore, 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 inquired. Referring to table 5, the BSR, the RRC, and the common data structure in the initial context configuration request message ticket or the pdu session resource configuration request message ticket are associated to obtain a new data structure as shown in table 5 below, so that the 5QI can be associated with the target user identifier.

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

I.e. according to the above mentioned target subscriber identity and the 5QI logarithmic array

The updating is performed according to the following updating principle.

When the data is backfilled with 5QI ═ 6 after being associated, the buffer status report BSR reports the pending transmission data volume of the transmission data with 5QI ═ 6.

When the data is backfilled with 5QI ═ 8 after being associated, the buffer status report BSR reports the pending transmission data volume of the transmission data with 5QI ═ 8.

When the data is backfilled with 5QI ═ 9 after being associated, the buffer status report BSR reports the pending transmission data volume of the transmission data with 5QI ═ 9.

Wherein, in the above-mentioned data transmission method with LCG ID of 7 in case three, the LCG ID of 7 reports 5QI of 6,8,9 traffic volume to be transmitted of transmission data of three service types at the same time, because the base station obtains the target user ID of the radio access network, the LCG ID corresponding to the target user ID, and the traffic Buffer Size to be transmitted of the logical channel group indicated by the logical channel group ID 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 contains the target user ID and the user temporary ID, and then obtains the initial context configuration request message ticket (or the protocol data unit session resource configuration request message) from the data of the operation domain of the radio access network, the initial context configuration request message ticket (or the protocol data unit session resource configuration request message ticket) includes a temporary user identifier and a 5QI, and the base station may associate the 5QI with the target user identifier according to the currently acquired data. Specific examples thereof include: the bearer is default to the normal user, 5QI 8 VIP user, and SVIP user, 6. Since each user establishes a connection for the first time, there is only one service type with 5QI of 6,8, and 9, if the current 5QI is 9, the buffer status report BSR reports the pending data volume of the transmission data of the service of the ordinary user with 5QI being 9; if the current 5QI is 8, the buffer status report BSR reports the amount of data to be transmitted of the transmission data of the service of the VIP user with 5QI being 8; if the current 5QI is 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 5QI being 6. Therefore, the problem that the calculation of the user perception rates of the transmission data of different service types cannot distinguish 5QI for statistics is solved.

In this way, in the above scheme, 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 volume to be transmitted of the logical channel group indicated by the logical channel group identifier is sent to the base station by the user equipment, and the base station may further obtain the data of the operation domain of the radio access network including the user temporary identifier corresponding to the target user identifier in the core network and the 5QI corresponding to the user temporary identifier. Because the data of the operating domain of the radio access network includes the corresponding relationship between the target user identifier of the radio access network and the user temporary identifier of the core network, and also includes the corresponding relationship between the user temporary identifier and the 5QI, the base station can associate the target user identifier of the radio access network and the 5QI in the BSR in a data backfill manner, thereby determining the corresponding relationship between the 5QI and the data volume to be transmitted of the logical channel group corresponding to the logical channel group identifier of the 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 differentiate the calculation of the user perceived rate of the transmitted data at different times from 5QI, statistics are performed. The data transmission method provided in the embodiment of the present invention further includes 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 obtained, the timestamps included therein need to be matched. Specifically, the buffer status report BSR includes a first timestamp, such as the first timestamp 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 includes a second timestamp, which is shown in table 3, where the second timestamp is a time when the base station receives the radio resource control RRC establishment request message; the initial context configuration request message ticket includes a third timestamp, which is shown in table 4, where the third timestamp is a time when the initial context configuration request message ticket is received by the base station, or the protocol data unit session resource configuration request message ticket includes a third timestamp, which is shown in table 4, where the third timestamp is a time when the protocol data unit session resource configuration request message ticket is received by the base station. Step 204 is performed again when the base station determines that the first timestamp is later than the third timestamp and the third timestamp is later than the second timestamp. As shown in table 5, the first timestamp is also associated to the data structure, 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 amount of data to be transmitted Buffer Size of the logical channel group indicated by the logical channel group identifier, and the current first timestamp is added, then the calculation of the user sensing rates of the transmission data at different times can be distinguished by 5QI for statistics.

Then, referring to table 1, in case four, when the base station receives the LCG ID of 5 in the buffer status report BSR, the base station reports the data volume to be transmitted of the transmission data with 5QI being three

service types

2,3, and 4 simultaneously in one logical channel group, and the base station cannot distinguish the service type corresponding to the transmission data of the current data volume to be transmitted and which of the 5QI corresponding to the service type is 2,3, and 4, so that the calculation of the user sensing rates of the transmission data of different service types cannot distinguish the 5QI for statistics.

In order to solve the problem in the fourth situation, an embodiment of the present invention provides another data transmission method, which is described in detail below with reference to fig. 7, and with reference to fig. 7.

301. And the base station receives the buffer status report BSR sent by the user equipment.

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

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

Wherein, the data of the operation domain of the core network is the operation support system (O domain for short) data; the data of the operation domain of the core network is obtained by monitoring a working state of a device of the core network by using an operation and main center-core (OMC-C), such as the OMC-C shown in fig. 2, where the OMC-C is connected to the radio access network through a Deep Packet Inspection (DPI) interface.

304. The base station acquires a 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 obtains a radio resource control RRC establishment request message ticket from data in an operation domain of the radio access network. Wherein, the RRC establishment request message is generated when the user equipment is in an idle mode, and if a Non Access Stratum (NAS) of the user equipment requests to establish a signaling connection, the user equipment initiates an RRC connection establishment request procedure. Exemplarily, 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, which includes: a target user identity (e.g., a cell-radio network temporary identifier (C-RNTI)) of the radio access network, and a user temporary identity corresponding to the core network (e.g., a Next Generation (NG) interface application protocol identity (AMF UE NG application protocol ID) between an access and mobility management function (AMF) and a User Equipment (UE), an AMF UE NGAP ID).

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

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

Specifically, in step 305, the base station first obtains certain detailed record (xDR) data from data in the operation domain of the core network. Wherein, the xDR may be a detailed record (CDR) of a voice call service, a detailed record (TDR) of a transaction, or a detailed record (IPDR) of TCP/IP (transmission control protocol/internet protocol) communication. Referring to the data structure of the xDR shown in table 6, the xDR data includes a start time of the xDR, an end time of the xDR, a subscriber identity (SUPI), a subscriber temporary identity (for example, an AMF UE NGAP ID), and a subscriber ticket type.

Starting time

AMF UE NGAP ID

TABLE 6

And then the base station acquires the user call ticket type corresponding to the user temporary identifier in the xDR data according to the user temporary identifier. That is, according to the AMF UE NGAP ID in table 3, the user ticket type is obtained in table 6.

306. And the base station associates the user ticket type with the target user identifier.

The user ticket type is used for representing the service type of a user in the ticket data, and can take the following numerical value, wherein the value of the user ticket type is 1 for representing a hypertext transfer protocol (HTTP) service, the value of the user ticket type is 2 for representing a hypertext transfer security protocol (HTTPs) service, the value of the user ticket type is 3 for representing a Domain Name System (DNS) service, the value of the user ticket type is 4 for representing other services, the value of the user ticket type is 5 for representing an Instant Messaging (IM) service, the value of the user type is 6 for representing a video statistical service, and the value of the user ticket type is 7 for representing a game statistical service.

For the current configuration, when the LCG ID is 5, a logical channel group simultaneously reports a data amount to be transmitted of transmission data with 5QI being 2,3,4 service types, and 5QI being 2 carries long-term evolution voice-over-speech (voice) service, 5QI being 3 carries game service, 5QI being 4 carries video service, and the same ue does not simultaneously transmit data of the three service types. Therefore, when the user ticket type is a game service, the 5QI at the moment can be determined to be 3; when the user ticket type is a video service, determining that 5QI at the moment is 4; when the call ticket type of the user is empty and the to-be-transmitted data Size of the current logical channel group is not equal to 0, it may be determined that 5QI at this time is 2. The above can prove that the user ticket types correspond to 5QI one by one.

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 identifier.

TABLE 7

According to the current user ticket type and the target user identification logarithm group

The updating is performed according to the following updating principle.

When the call ticket type of the user is empty and Buffer Size_{LCG ID＝5}When the buffer status report BSR is not equal to 0, the buffer status report BSR reports the pending transmission data volume of the transmission data with 5QI ═ 2.

When the user ticket type is a game service, the buffer status report BSR reports a data volume to be transmitted of transmission data with 5QI ═ 3.

When the user's call ticket type is video service, the call ticket is bufferedThe buffer status report BSR reports the amount of data to be transmitted of the transmission data with 5QI ═ 4.

Wherein, in the another data transmission method with LCG ID of 5 in the fourth case, the LCG ID of 5 reports 5QI of 2,3,4 traffic volume to be transmitted of the transmission data simultaneously, because the base station obtains the target user ID of the radio access network, the LCG ID corresponding to the target user ID, and the Buffer Size of the traffic volume to be transmitted of the logical channel group indicated by the logical channel group ID 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 contains the target user ID and the user temporary ID, and then obtains the xDR data from the data of the operation domain of the core network, the xDR data contains the user temporary ID and the user ticket types, the user ticket types correspond to 5QI one by one, the base station can associate the user ticket type with the target user identifier according to the currently acquired data, that is, the base station associates the 5QI with the target user identifier. Specific examples thereof include: the 5QI ═ 2 carries the voice service, the 5QI ═ 3 carries the game service, and the 5QI ═ 4 carries the video service. 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 data volume to be transmitted Buffer Size is not equal to 0, it can be determined that the data volume to be transmitted of the transmission data of the voice service with 5QI ═ 2 reported by the Buffer status report BSR is to be transmitted; when the user ticket type is the game service, the buffer status report BSR can be determined to report the data volume to be transmitted of the transmission data of the game service with 5QI ═ 3; when the user ticket type is the video service, it may be determined that the buffer status report BSR reports the amount of data to be transmitted of the transmission data of the video service with 5QI ═ 4. Therefore, the problem that the calculation of the user perception rates of the transmission data of different service types cannot distinguish 5QI for statistics is solved.

Thus, 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 amount of data to be transmitted of the logical channel group indicated by the logical channel group identifier to the base station, and the base station can also obtain the data of the operation domain of the radio access network including the user temporary identifier corresponding to the target user identifier in 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, wherein the data of the operation domain of the radio access network includes the corresponding relationship 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 corresponding relationship between the user temporary identifier and the user ticket type, and the user ticket types correspond to 5QI one to one, so that the base station can backfill the target user identifier of the radio access network in the BSR and the user ticket type in a data backfill manner The call ticket types are correlated, that is, the base station determines the corresponding relationship between the 5QI and the data volume to be transmitted of the logical channel group corresponding to the logical channel group identifier of the uplink transmission data, thereby solving the problem that the calculation of the user perception rates of the transmission data of different service types cannot distinguish the 5QI for statistics.

To differentiate the calculation of the user perceived rate of the transmitted data at different times from 5QI, statistics are performed. The data transmission method provided in the embodiment of the present invention further includes time verification. Specifically, after step 305, that is, after acquiring the BSR, the RRC establishment request message, and the xDR data, the timestamps included therein need to be matched. Specifically, the buffer status report BSR includes a first timestamp, i.e. the 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, the 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, where the third timestamp is the end time of the statistical xDR message. The base station determines that the first timestamp is later than the second timestamp, and the first timestamp and the second timestamp are both earlier than the third timestamp, and then performs 306. As shown in table 7, the first timestamp is associated to the data structure, 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 amount of data to be transmitted Buffer Size of the logical channel group indicated by the logical channel group identifier, and then the current first timestamp is added, the calculation of the user sensing rates of the transmission data at different times can be distinguished by 5QI for statistics.

By combining the situation that the base station configures 5QI for 8 logical channel groups, the data transmission method provided by the embodiment of the present invention can implement that 5QI can be distinguished for statistics by calculating the user perception rates of transmission data of different service types during the uplink data transmission. 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 is not limited to what kind of 5QI is configured for which logical channel group.

An embodiment of the present invention also provides a base station, and fig. 8 is a schematic structural diagram of a base station having a data transmission method provided in an embodiment of the present invention, and as shown in fig. 8, the base station 40 includes: receiving unit 401, obtaining unit 402, and 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 identifying a target user of a wireless access network, identifying a logical channel group corresponding to the target user, and indicating the data volume to be transmitted of the logical channel group by the logical channel group identification.

An obtaining unit 402 is configured to obtain data of an operation domain of a radio access network.
