[0100] The present application is further described in detail below in conjunction with the accompanying drawings and embodiments.

[0101] In the architecture of decentralized social services (also known as social applications), there are only two roles: client and relay server. Each user runs a client, and each user has two keys, a public key and a private key; the public key can be regarded as a user name or account, and the private key can be regarded as a key. When publishing (posting in English), the user uses the private key to sign the published information (such as image information or text information), and sends the signed information to multiple relay servers through the client; the relay server can store the information published by the client, forward the information, and return the query results according to the query request of the client. In the scenario where the query results are received, the client can use the public key to verify the query results to determine the authenticity of the information, that is, the signature is verified on the client side.

[0102] From the above description, it can be seen that in a decentralized scenario, a client will not interact with other clients, that is, clients do not communicate with each other, and there is no information exchange between relay servers, that is, relay servers do not communicate with each other.

[0103] Here, before performing application layer data transmission, the terminal needs to initiate a protocol data unit (PDU) session establishment process. Through the PDU session establishment process, resources can be allocated for one or more PDU sessions and corresponding QoS flows of the terminal, and corresponding data radio bearers (DRBs) can be established; one PDU session may correspond to one or more QoS flows. Specifically, Figure 1 As shown, a base station (such as a next generation radio access network (NG-RAN)) can establish one or more DRBs for each PDU session and associate and map the QoS flow with the DRB based on preset rules.

[0104] In related technologies, a PDU session for data services and a PDU session for audio and video services (which can be understood as intelligent media services (IMS)) are usually configured for the terminal; that is, each terminal usually maintains two PDU sessions, and all service data will use the same PDU session. After the PDU session is established, for decentralized social applications, such as Figure 2As shown in the figure, when the client (such as clientA, clientB and clientC) sends data, after determining that the data type is text, picture or video, the data is sent to a group of relay servers (such as Relay1, Relay2, Relay3, Relay4 and Relay5) through the PDU session. Since the Internet Protocol (IP) addresses (also called destination addresses) of these relay servers are different, the client side needs to construct a large number of data packets to send the same data, which will consume a lot of wireless air interface resources and bring huge pressure to the wireless network; among them, Figure 3 As shown, the data packet may carry the destination addresses of different relay servers (such as the destination addresses of Relay1, Relay2, and Relay3).

[0105] To address the above issues, in the actual transmission process, the terminal will use converged transmission and other technical means to transmit data to reduce the use of wireless air interface resources. That is, the terminal compresses the data and sends the compressed data to the base station; the base station decompresses the compressed data and transmits the decompressed data to the network side.

[0106] In the related technology, each PDU session corresponds to a session aggregate maximum bit rate (Session-AMBR); wherein, Session-AMBR defines the bit rate of the maximum non-guaranteed bit rate (non-GBR) QoS flow of the PDU session, that is, the sum of the bit rates of all non-GBR QoS flows of a PDU session needs to be less than or equal to the Session-AMBR of the PDU. When the session management function (SMF) receives the PDU session establishment request sent by the terminal, it queries the Session-AMBR in the corresponding user subscription data from the unified data management function (UDM), and can modify it based on the contract value, local policy or policy control function (PCF) policy; then, the Session-AMBR is sent to the user plane function (UPF) through the N4 interface, and the Session-AMBR is sent to the base station and the terminal through the N2 interface, so that the terminal and UPF can perform QoS control based on the Session-AMBR. At the same time, the base station can determine the user equipment aggregation maximum bit rate (UE-AMBR) based on the Session-AMBR.

[0107] At the same time, each terminal is configured with a UE-AMBR, which defines the maximum bit rate of the terminal's non-GBR QoS flow. That is, the sum of the bit rates of all non-GBR QoS flows of a terminal needs to be less than or equal to the UE-AMBR. UE-AMBR is user subscription data, which the Access and Mobility Management Function (AMF) can query from the UDM and send to the base station, which is configured by the base station based on the received UE-AMBR; the UE-AMBR value set by the base station is the sum of the Session-AMBRs of all PDU sessions with active user planes in the base station, and the set UE-AMBR value is less than or equal to the UE-AMBR value received from the AMF.

[0108] When the terminal needs to send service data, the terminal sends a scheduling request to the base station through the physical uplink control channel (PUCCH) resource of the scheduling request (which can be expressed as Scheduling Request in English); when the base station receives the scheduling request, it will schedule the terminal so that the terminal can transmit the media access control layer (MAC) PDU on the resources allocated by the base station. The MAC PDU can contain a buffer status report (BSR) to indicate the size of the data contained in the uplink data buffer. If the BSR received by the base station is greater than 0, it will continue to schedule the terminal so that the terminal can transmit data. In addition, the base station side will also count the bit rate of the QoS flow of non-GBR services; if the sum of the bit rates of all non-GBR QoS flows is greater than UE-AMBR, the base station will stop scheduling the terminal. Therefore, for UE-AMBR, the base station will collect statistics based on the actual transmission data of the decentralized service. For example, for the converged audio and video stream data, the bit rate of the QoS flow of the non-GBR service counted by the base station will generally not exceed UE-AMBR, which will not affect the scheduling of the terminal.

[0109] However, during the data transmission process between the base station and the network side, since the base station will restore (i.e., decompress) the data compressed by the terminal, the restored data traffic will increase significantly, resulting in an increase in the data traffic reported to the UPF. In this case, since the data traffic received by the UPF is different from the data traffic actually transmitted over the air interface, if the UPF performs QoS traffic control or billing based on the received data traffic, then it may cause QoS traffic control and billing errors due to exceeding the Session-AMBR; in other words, the underlying converged transmission may cause QoS traffic control and billing errors, resulting in service interruption.

[0110] Based on this, in various embodiments of the present application, when a PDU session is established, the network side synchronizes information with the terminal on whether the session supports aggregated transmission capabilities, and obtains traffic information actually generated by the terminal applying aggregated transmission. In this way, the network side can perform correct QoS traffic control on the service data of the aggregated transmission, thereby ensuring the normal operation of the service.

[0111] The present application embodiment provides an information transmission method, which is applied to a terminal, such as Figure 4 As shown, the method includes:

[0112] Step 401: Sending first information to a first function, where the first information is used to indicate the converged transmission capability of the terminal, and the first function is at least used to perform session management;

[0113] Step 402: Receive second information from the first function, where the second information is used to indicate the converged transmission capability of the network associated with a first session, where the first session is used for the terminal to send and / or receive service data.

[0114] In actual application, the terminal may be referred to as user equipment (UE), terminal equipment, equipment or user, etc. The embodiment of the present application does not limit the name of the terminal, as long as its function is realized. In addition, the first function is at least used for session management, which can also be understood as the first function at least being able to perform session management, and the first function may include SMF, which is not limited in the embodiment of the present application, as long as its function is realized.

[0115] In actual application, the terminal may send the first information to the first function during the process of establishing a session.

[0116] Based on this, in one embodiment, the specific implementation of step 401 may include:

[0117] A session establishment request is sent, where the session establishment request includes the first information.

[0118] That is to say, when applying to establish a PDU session, the terminal informs the core network (such as the fifth generation mobile communication technology (5G) core network (5GC)) of the terminal's converged transmission capability.

[0119] Exemplarily, the terminal may add a PDU Convergence Transmission Supported field in the 5G session management capability information element (5GSM capability IE) and set the first information in the field.

[0120] Here, in actual application, after the terminal generates a session establishment request, the session establishment request can be sent to the first function through a third function; wherein the third function is at least used for access and mobility management.

[0121] Among them, the third function is at least used for access and mobility management, and it can also be understood that the third function can at least perform access and mobility management. The third function may include AMF. The embodiment of the present application does not limit this, as long as its function is realized.

[0122] In one embodiment, the first information includes one of the following:

[0123] third information, where the third information is used to indicate that the terminal does not support converged transmission capability;

[0124] Fourth information, the fourth information is used to indicate that the terminal supports IPv4 converged transmission capability;

[0125] Fifth information, the fifth information is used to indicate that the terminal supports IPv6 converged transmission capability;

[0126] The sixth information is used to indicate that the terminal supports IPv4 and IPv6 converged transmission capabilities.

[0127] In actual application, when the first information is implemented through N bits, it can respectively correspond to the terminal not supporting aggregate transmission capability, the terminal supporting IPv4 aggregate transmission capability, the terminal supporting IPv6 aggregate transmission capability, and the terminal supporting IPv4 and IPv6 aggregate transmission capability, and the value of N is an integer greater than or equal to 1.

[0128] In this case, the first information can be implemented by 2 bits, the third information can be represented by 00, corresponding to the terminal not supporting the converged transmission capability; the fourth information can be represented by 01, corresponding to the terminal supporting the IPv4 converged transmission capability; the fifth information can be represented by 10, corresponding to the terminal supporting the IPv6 converged transmission capability; the sixth information can be represented by 11, corresponding to the terminal supporting the IPv4 and IPv6 converged transmission capability.

[0129] In actual application, after the first function receives the first information from the terminal, it can return the second information to the terminal through a session establishment acceptance message.

[0130] Based on this, in one embodiment, receiving the second information from the first function includes:

[0131] A session establishment accept message is received, where the session establishment accept message includes the second information.

[0132] Here, in actual application, after the first function generates a session establishment acceptance message, the session establishment acceptance message can be sent to the terminal through the third function; that is, the first function informs the terminal of the converged transmission capability of the network side.

[0133] Exemplarily, the first function may add a PDU Convergence Transmission Indicator field to a Session Aggregation Maximum Bit Rate Information Element (Session-AMBRIE), and set the second information in the field.

[0134] In one embodiment, the second information may include one of the following:

[0135] seventh information, where the seventh information is used to indicate that the network associated with the first session does not support aggregate transmission capability;

[0136] Eighth information, where the eighth information is used to indicate that the network associated with the first session supports IPv4 converged transmission capability;

[0137] Ninth information, the ninth information is used to indicate that the network associated with the first session supports IPv6 converged transmission capability;

[0138] The tenth information is used to indicate that the network associated with the first session supports IPv4 and IPv6 converged transmission capabilities.

[0139] In actual application, when the second information is implemented through M bits, it can respectively correspond to the network associated with the first session not supporting aggregated transmission capability, the network associated with the first session supporting IPv4 aggregated transmission capability, the network associated with the first session supporting IPv6 aggregated transmission capability, and the network associated with the first session supporting IPv4 and IPv6 aggregated transmission capability, and the value of M is an integer greater than or equal to 1.

[0140] In this case, exemplarily, in the related technology, Session-AMBR IE is defined as 8 bits, and the second information can be implemented by using 2 unused bits of the 8 bits. Assuming that the last 2 bits are used, the seventh information can be represented by 00000000, corresponding to the network associated with the first session does not support aggregate transmission capability; the eighth information can be represented by 00000001, corresponding to the network associated with the first session supports IPv4 aggregate transmission capability; the ninth information can be represented by 00000010, corresponding to the network associated with the first session supports IPv6 aggregate transmission capability; the tenth information can be represented by 00000011, corresponding to the network associated with the first session supports IPv4 and IPv6 aggregate transmission capability.

[0141] In actual application, after receiving the second information from the first function, the terminal may save the second information locally, so as to perform uplink data transmission based on the second information and actual needs later.

[0142] Accordingly, the embodiment of the present application also provides an information transmission method, which is applied to the first function, such as Figure 5 As shown, the method includes:

[0143] Step 501: receiving first information from a terminal, where the first information is used to indicate the converged transmission capability of the terminal, and the first function is at least used to perform session management;

[0144] Step 502: Send second information to the terminal and the access network device, and send eleventh information to the second function, wherein the second information is used to indicate the converged transmission capability of the network associated with the first session, the first session is used for the terminal to send and / or receive service data, the second function is at least used for user plane management, and the eleventh information is used to indicate whether the first session supports converged transmission.

[0145] In actual application, the access network device may also be referred to as a radio access network (RAN) device, specifically a base station, such as a next generation base station (gNB), etc., which is not limited in the embodiments of the present application. In addition, the second function is at least used for user plane management, which can also be understood as the second function being able to at least perform user plane management. Specifically, the second function may include a UPF, which is not limited in the embodiments of the present application, as long as its function is realized.

[0146] In actual application, in step 502, after receiving the first information, the first function sends the second information to the access network device to inform the access network device of the converged transmission capability of the network associated with the first session. In this way, when the terminal subsequently transmits data, the access network device can obtain the converged transmission capability of the network, and if the network supports the converged transmission capability, the bit rate actually generated by the terminal applying the converged transmission is sent to the second function so that the second function can perform QoS traffic control.

[0147] In addition, the first function will also send the eleventh information to the second function so that the second function performs QoS traffic control based on the eleventh information; wherein, the eleventh information can be sent to the second function through an N4 session establishment request.

[0148] Specifically, in one embodiment, sending the eleventh information to the second function includes:

[0149] An N4 session establishment request is sent to the second function, where the N4 session establishment request includes the eleventh information.

[0150] In actual application, the first function can send the eleventh information to the second function through an N4 session establishment request; that is, when creating the N4 session establishment request, the first function informs the second function of the converged transmission capability of the session.

[0151] Exemplarily, the first function may add a PDU aggregation transmission indication field in the QoS enforcement rule (QER), and set the eleventh information in the field.

[0152] When the eleventh information indicates that the first session supports converged transmission, the second function can use the bit rate actually generated by the terminal applying converged transmission as the basis for QoS flow control and billing, thereby avoiding QoS flow control and billing errors caused by underlying converged transmission.

[0153] Accordingly, the embodiment of the present application also provides an information transmission method, which is applied to an access network device, such as Figure 6As shown, the method includes:

[0154] Step 601: receiving second information from a first function, where the first function is at least used for session management, and the second information is used to indicate an aggregate transmission capability of a network associated with a first session, where the first session is used for a terminal to send and / or receive service data;

[0155] Step 602: for the first session, determining the bit rate actually generated by the terminal applying the aggregated transmission;

[0156] Step 603: Send the determined bit rate to a second function, where the second function is at least used for user plane management.

[0157] In actual application, in step 602, when the terminal sends service data based on the first session, the access network device can calculate the bit rate value within the average window of the aggregate maximum bit rate (AMBR) according to the BSR reported by the terminal, the aggregate transmission information and the aggregate maximum bit rate information of the terminal, and use the calculated bit rate value within the AMBR average window as the actual bit rate generated by the terminal applying the aggregate transmission.

[0158] It should be noted that the AMBR averaging window is used to count Session-AMBR and UE-AMBR; wherein the AMBR averaging window parameter may be a standardized value, such as 2 seconds.

[0159] After determining the bit rate actually generated by the terminal applying the converged transmission, the first function may send the determined bit rate to the second function via a user plane message.

[0160] Specifically, in one embodiment, sending the determined bit rate to the second function includes:

[0161] Sending a user plane message to the second function, wherein the user plane message includes the determined bit rate.

[0162] In actual application, the access network device may extend the message header of the user plane message, and carry the determined bit rate through the extended message header.

[0163] Specifically, in one embodiment, the determined bit rate is set in the message header of the user plane message.

[0164] Exemplarily, the access network device adds the determined bit rate to an extended message header of a user plane message (such as uplink PDU session information (UL PDU SESSION INFORMATION)), and sends it to the second function.

[0165] Accordingly, the embodiment of the present application also provides an information transmission method, which is applied to the second function, such as Figure 7 As shown, the method includes:

[0166] Step 701: Receive eleventh information sent by a first function, where the second function is at least used for user plane management, and the eleventh information is used to indicate whether the first session supports converged transmission;

[0167] Step 702: receiving a bit rate actually generated by the terminal applying aggregated transmission for the first session, which is sent by the access network device;

[0168] Step 703: Use the received bit rate to determine whether to perform flow control.

[0169] In one embodiment, the specific implementation of step 701 may include:

[0170] An N4 session establishment request is received, where the N4 session establishment request includes the eleventh information.

[0171] In one embodiment, the specific implementation of step 702 may include:

[0172] A user plane message sent by the access network device is received, where the user plane message includes the bit rate.

[0173] Here, in actual application, after the second function receives the bit rate, it can compare the received bit rate with the contract value of the terminal to determine whether to perform flow control; the contract value of the terminal can be understood as the maximum bit rate corresponding to a session, in other words, the upper limit of the sum of the bit rates of all QoS flows of a session.

[0174] Specifically, if the received bit rate is less than or equal to the contract value of the terminal, it means that the bit rate actually generated by the aggregated transmission meets the bit rate requirements, and flow control is not required; if the received bit rate is greater than the contract value of the terminal, it means that the bit rate actually generated by the aggregated transmission meets the bit rate requirements, and flow control can be performed at this time.

[0175] Here, in actual application, the second function may obtain the contract value of the terminal from the first function. Exemplarily, the second function receives the N4 session establishment request sent by the first function, and the N4 session establishment request may also include the contract value of the terminal. The specific method of obtaining the contract value is not limited in the embodiment of the present application.

[0176] In the information transmission method provided by the embodiment of the present application, the terminal sends first information to the first function, the first information is used to indicate the converged transmission capability of the terminal, and the first function is at least used for session management; receives second information from the first function, the second information is used to indicate the converged transmission capability of the network associated with the first session, and the first session is used for the terminal to send and / or receive service data; and after the first function receives the first information from the terminal, it sends the second information to the terminal and the access network device, and sends the eleventh information to the second function, and the eleventh information is used to indicate whether the first session supports converged transmission. In the technical solution provided by the embodiment of the present application, the network side synchronizes the information with the terminal on whether the session supports converged transmission, and obtains the traffic information actually generated by the terminal applying converged transmission, so that the network side can perform correct QoS traffic control on the converged transmission service data, so as to ensure the normal operation of the service.

[0177] The present application is further described in detail below in conjunction with application examples.

[0178] In this application example, in order to solve the flow control and billing errors caused by Session-AMBR data distortion caused by air interface convergence transmission in a decentralized scenario, a transmission strategy configuration scheme is proposed. Specifically, when a PDU session is established, the indication information of whether the PDU convergence transmission capability is supported is added to multiple signalings to achieve information synchronization of the convergence transmission capability between the network side and the terminal. In addition, during uplink data transmission, the actual air interface transmission bit rate is sent to the UPF through the N3 interface.

[0179] In actual application, during the process of establishing a PDU session, such as Figure 8 As shown, the following steps are included:

[0180] Step 801: UE sends a PDU session establishment request (PDU Session Establishment Request) to AMF;

[0181] Here, when the UE initiates a PDU session establishment request, the PDUConvergence Transmission Supported (i.e., the first information mentioned above) field can be added to the 5GSM capability IE and selected according to the actual capability of the UE; among which, the PDU aggregation transmission capability support field is used to indicate whether the UE supports PDU aggregation transmission.

[0182] Exemplarily, if the convergence bit (Convergence) in the PDU convergence transmission capability support information is expressed as 00, it can indicate that the UE does not support the PDU convergence transmission capability; if the PDU convergence transmission capability support information is expressed as 01, it can indicate that the UE supports the PDUIPv4 convergence transmission capability; if the PDU convergence transmission capability support information is expressed as 10, it can indicate that the UE supports the PDUIPv6 convergence transmission capability; if the PDU convergence transmission capability support information is expressed as 11, it can indicate that the UE supports the PDUIPv4 and IPv6 convergence transmission capabilities.

[0183] That is to say, the UE sends the information of whether its capabilities support aggregated transmission to the AMF through a PDU session establishment request.

[0184] Step 802: After receiving the PDU session establishment request, the AMF selects an SMF and sends a PDU session establishment management context request (Nsmf_PDUSession_CreateSMFContext Request) to the selected SMF;

[0185] The PDU session management context establishment request carries the PDU aggregation transmission capability support information.

[0186] Step 803: After receiving the PDU session management context establishment request, the SMF returns a PDU session management context establishment response (Nsmf_PDU Session_CreateSMFContext Response) to the AMF, and then executes step 804;

[0187] Step 804: SMF sends an N4 Session Establishment Request (ie, the eleventh message mentioned above) to UPF.

[0188] In actual application, when SMF creates an N4 session establishment request, it can add a PDU Convergence Transmission Indicator field in the QER to indicate whether the session supports the PDU Convergence Transmission capability. If the PDU Convergence Transmission Indicator field indicates that the session supports the PDU Convergence Transmission capability, the subsequent UPF will use the actual air interface transmission data (i.e. Session-AMBR) transmitted by the gNB through GTP-U as the basis for QoS flow control and billing.

[0189] Step 805: After receiving the N4 session establishment request, the UPF returns an N4 session establishment response (N4 Session Establishment Response) to the UPF;

[0190] Step 806: After receiving the N4 session establishment response, SMF sends an N1N2 information transfer request (Namf_Communication_N1N2MessageTransfer) to AMF;

[0191] Step 807: After receiving the N1N2 information transmission request, the AMF sends an N2PDU session request (N2 PDUSession Request) to the RAN;

[0192] In actual application, AMF sends non-access stratum (NAS) signaling (expressed as message in English) to RAN, where the non-access stratum signaling includes N2PDU session request.

[0193] Step 808: After receiving the N2 PDU session request, the RAN sends a PDU session establishment accept message (PDUSession Establishment Accept) to the UE;

[0194] Here, when SMF checks the aggregation bit of the PDU aggregation transmission capability support information in the PDU session establishment request, if the aggregation bit indicates that the terminal supports the aggregation transmission capability, SMF will use the Session-AMBR IE in the PDU session establishment acceptance message to indicate whether the network supports the PDU aggregation transmission capability.

[0195] Exemplarily, if the PDU converged transmission indication information in the Session-AMBR IE (i.e., the second information mentioned above) is expressed as 00000001, it can indicate that the network supports the capability of PDU IPv4 converged transmission; if the PDU converged transmission indication information in the Session-AMBR IE is expressed as 00000010, it can indicate that the network supports the capability of PDU IPv6 converged transmission; if the PDU converged transmission indication information in the Session-AMBR IE is expressed as 00000011, it can indicate that the network supports the capability of PDU IPv4 and IPv6 converged transmission.

[0196] Step 809: RAN returns N2 PDU Session Response to AMF;

[0197] Here, after RAN allocates resources for the PDU session, it returns an N2 PDU session response to the AMF; the N2 PDU session response carries the allocated resource information.

[0198] It should be noted that the execution order of step 808 and step 809 is not specific.

[0199] Step 810: After receiving the PDU session establishment accept message, the UE sends uplink data (which can be expressed as Uplink Data in English) to the RAN;

[0200] Here, after receiving the PDU session establishment acceptance message, the UE saves the indication information of whether the network side supports the PDU aggregation transmission capability locally, and subsequently transmits data as needed.

[0201] Step 811: After receiving the uplink data, the RAN sends the uplink data to the UPF;

[0202] In actual application, RAN calculates the Session-AMBR value (i.e., the actual bit rate generated by the above-mentioned terminal applying the converged transmission) within the AMBR averaging window (e.g., 2s) based on the BSR, UE-AMBR and converged transmission related information reported by the underlying UE; the calculated Session-AMBR value is set in the message header of the uplink PDU session message and sent to the UPF along with the uplink data.

[0203] Here, the RAN applies the bit rate obtained by actual air interface wireless resource consumption after converged transmission, calculates and sends the actual bit rate to the UPF, and then executes step 812.

[0204] Step 812: UPF performs comparison and judgment.

[0205] In actual application, UPF compares the calculated Session-AMBR value (also known as the real Session-AMBR value) with the user contract value in the N4 session establishment request to determine whether to trigger QoS flow control. Since UPF obtains the real Session-AMBR value from RAN, it can avoid service interruption caused by QoS flow control.

[0206] In this application example, in a decentralized social scenario, by adding PDU aggregation transmission-related message fields in the signaling and sending the actual Session-AMBR value of the air interface to the UPF through GTP-U, service interruption caused by QoS traffic control can be avoided while reducing the waste of uplink air interface resources. In addition, the current signaling process and message format can be reused to the maximum extent, thereby increasing system compatibility.
