In the description of the present invention, the term "plurality" means two or more unless otherwise specified.

Fig. 1 is a schematic view of an application scenario of a method for using QFI as an index of QoS Profiles provided in the embodiment of the present application, and as shown in fig. 1, the method for configuring a mapping relationship from QoS flow to RB for a network side device and a terminal provided in the embodiment of the present application may be used for a new radio access network (new RAN), where the new RAN includes a next generation access network device gNB and an enhanced L TE access network device eNB.

The following is a description of a core network according to an embodiment of the present invention, where the core network includes a core network control plane and a core network user plane.

The core network Control Plane, i.e. the Next Generation Control Plane (NG-CP), includes a network element repository function (network element registration and discovery function to enable discovery and communication between NG-CP network elements), an access and mobility management function (to process UE-level access and mobility management), a session management function (to support UE IP address allocation, user Plane entity selection and Control, and also includes Qos related rules, session related charging and legal detection), a policy Control function (to provide dynamic policies, such as Qos, charging, access Control, routing, etc., for other functions), and a network capability opening function (to provide part of open capability information for a third party);

As shown in fig. 2, which is a schematic flow diagram for configuring QoS Profiles according to an embodiment of the present invention, in an embodiment of the present invention, a core network may configure a corresponding relationship between QoS Profiles and QFI for a network side device and a terminal through a core network control plane or a user plane. In an optional manner, when the configuration is performed through the control plane, the core network configures a corresponding relationship between QoS Profiles and QFI for a Non Access Stratum (NAS) layer of the terminal through NAS layer signaling; the core network configures the corresponding relation between QoS Profiles and QFI for an access stratum (Acces Sratum, AS) layer of network side equipment through NAS layer signaling;

further, the network side device receives the core network NAS layer signaling and then transmits the core network NAS layer signaling to the terminal through the AS layer signaling of the network side device, and configures the corresponding relation between the QoS Profiles and the QFI for the NAS of the terminal or the network side device configures the corresponding relation between the QoS Profiles and the QFI for the AS layer of the terminal through the AS layer signaling.

In another optional mode, the core network configures the corresponding relationship between QoS Profiles and QFI for the network side device and the terminal through the user plane. The NAS layer flow and the AS layer flow are actually from the perspective of a protocol stack, and AS shown in fig. 3, they are schematic diagrams of protocol stack structures of a control plane and a user plane corresponding to the NAS layer and the AS layer. The core network can also configure the corresponding relation between QoS Profiles and QFI for the AS layers of the network side equipment and the base station through the user plane.

The embodiments of the present invention will be described in further detail with reference to the drawings attached hereto.

As shown in fig. 4, a system for configuring QoS Profiles and data transmission according to an embodiment of the present invention includes: a sending device 10 and a transmission device 20 and a device 30 for configuring QoS Profiles.

The core network 10 is used for determining the corresponding relation between QoS Profiles and QFI; and configuring the corresponding relation between the QoS Profiles and the QFI to a network side device through a transceiver and/or transmitting the corresponding relation between the QoS Profiles and the QFI to a terminal through the network side device.

And the sending equipment 20 is used for determining QFI corresponding to QFI L ES required by the service according to the corresponding relation between QOS PROFI L ES and QFI, and sending a QoS flow data packet corresponding to the QFI.

The receiving device 30 is configured to receive, through the transceiver, a QoS flow data packet containing QFI sent by the sending end; and determining QoSPprofiles corresponding to the QFI contained in the received QoS flow data packet according to the corresponding relation between the QoS Profiles and the QFI.

According to the scheme, the core network equipment sends the corresponding relation between the QoS Profiles and the QFIs to the network side equipment, the corresponding relation between the QoS Profiles and the QFIs configured for the terminal by the core network equipment is sent to the terminal through the network side equipment, when a service requirement exists, the network side equipment or the terminal determines the QFIs corresponding to the QoS Profiles of the service requirement according to the corresponding relation between the QoS Profiles and the QFIs, and sends a QoS flow data packet containing the determined QFIs, after the receiving end receives the QoS flow data packet containing the QFIs sent by the sending end, the QoS Profiles information containing the QFIs corresponding to the QFIs contained in the QFIs is determined according to the corresponding relation between the QoS Profiles and the QFIs, the sending end does not need to independently configure the QFIs L information of the QoS flow data packet, and the receiving end can determine the QoS Profiles information of the received QFIs according to the corresponding relation between the QoS Profiles and the QFIs, so that signaling interaction between systems in a data transmission process is simplified, and signaling overhead is saved.

The device with the relevant function module of the core network can configure the corresponding relation between QoS Profiles and QFI for the network side device and the terminal. Specifically, the correspondence between QoS Profiles and QFI may be understood as taking QFI as an index of QoSProfiles, and each QFI value uniquely corresponds to one QoS profile; each QoS profile uniquely corresponds to a value of QFI.

It can be understood that, before the core network configures the corresponding relationship between QoS Profiles and QFI for the network side device and the terminal, the protocol already gives the rules of QoS Profiles corresponding to different service requirements, and when the core network configures the corresponding relationship between QoS Profiles and QFI for the network side device and the terminal, an optional manner is that the core network determines qosprofils of specific service requirements according to the protocol specification when establishing a data or service transmission request according to the network side device or the terminal, and configures QFI corresponding to QoS Profiles of specific service requirements for the network side device and the terminal.

After receiving the corresponding relation between the QoS Profiles and the QFI configured by the core network, the network side device and the terminal locally store the corresponding relation between the QoS Profiles and the QFI, and send a QoSflow data packet containing the QFI according to the QFI configured by the core network, without separately configuring signaling to inform the QoS Profiles corresponding to the QoS flow of the opposite terminal. When a processing function or a protocol sub-layer related to the RB of the receiving end receives the QoS flow data packet, according to the corresponding relation between QoSPprofiles and QFIs configured by the core network, the QoS Profiles of the QoS flow data packet can be rapidly determined through the QFIs of the received QoS flow data packet, and the mapping relation between the QoS flow data packet and the RB is stored.

Another optional mode is that the core network determines QoS Profiles of different service requirements according to the rules of the QoS Profiles corresponding to different service requirements given by the protocol, configures the corresponding relationship between the QoS Profiles and the QFI, and configures the corresponding relationship between the QoS Profiles and the QFI to the network side device and the terminal in advance.

After receiving the corresponding relationship between the QoS Profiles and the QFI configured by the core network, the network side device and the terminal locally store the corresponding relationship between the QoS Profiles and the QFI, and when the network side device or the terminal establishes a data or service transmission request, the sending end further needs to determine the QoS Profiles with the closest service requirements and the QFI corresponding to the QoS Profiles by searching the corresponding relationship between the QoS Profiles and the QFI, and then sends a QoS flow data packet containing the QFI to the opposite end. When a processing function or a protocol sub-layer related to the RB of the receiving end receives the QoS flow data packet, according to the corresponding relation between the QoS Profiles and the QFIs configured by the core network, the QoS Profiles of the QoS flow data packet can be rapidly determined through the QFIs of the received QoS flow data packet, and the mapping relation between the QoS flow data packet and the RB is stored.

The core network may configure the corresponding relationship between QoS Profiles and QFI for the network side device and the terminal through the control plane signaling. The core network may also configure the corresponding relationship between QoS Profiles and QFI for the network side device and the terminal in a user data packet manner. For example, the information of the corresponding relationship between QoSProfiles and QFI is carried in a downlink user data packet between the core network and the network side device. The core network can also inform the terminal QoS Profiles and QFI corresponding relation through NAS layer signaling. The QoS Profiles comprise one or more of time delay indexes, packet loss rates, speed and the like required by QoS flow.

The other possible mode is that the network side equipment informs the corresponding relation of the QoS Profiles and the QFI in a user plane control Data unit mode, wherein the user plane control Data unit comprises control PDUs of any Protocol layer such as PDAP, PDCP, R L C, MAC and the like, for example, a mode of Packet Data Convergence Protocol (PDCP) control PDUs, indicating the corresponding relation of the QSProfiles and the QFI, the terminal receives the PDCP control PDUs, and maps the QoS flow indicated by the QFI of the QoS flow to the RB.

A method for configuring a correspondence relationship between QFI and qos prox L ES for a network side device and a terminal by using a core network device as an example will be described in detail below.

As shown in fig. 5, a schematic process diagram of a core network device configured for a network side device and a terminal and using QFI as QoS Profiles index is provided for the embodiment of the present invention.

Step 1, when user equipment has a data transmission requirement, sending an RRC Connection establishment Request to network side equipment, and carrying NAS information of the PDU creation Request in an RRC Connection Setup Request or an RRC Connection reconfiguration Request by a terminal;

and step 2, the base station receives the NAS PDU and then sends the NAS PDU to a core network.

Step 3, the core network carries QoS Profiles information with QFI as index in PDU type Resource Setup Request;

and 4, after receiving the QoS Profiles information which is configured by the core network and takes QFI as the index, the base station replies a confirmation message PDU (PDU session Resource setting Response) to the core network, and the QoS Profiles information which takes QFI as the index is locally stored in the base station.

And step 5, after receiving the PDU _ Sesion _ ResourceSetup _ Response sent by the base station, the core network sends the PDU _ Sesion _ Seestablishment information carrying the QoS Profiles information with QFI as the index to the base station and transmits the PDU _ Sesion _ establishment information to the terminal through the base station.

And step 6, after receiving the NAS PDU sent by the core network, the network side device sends the NAS information established by carrying the PDU session to the terminal side through the RRC Connection setup Complete or RRC Connection Reconfiguration Complete.

After receiving the configuration information, the terminal locally stores the corresponding relationship between the QFI and the QOS PROFI L ES, the terminal can ensure the corresponding relationship between the QFI and the QOS PROFI L ES in an NAS layer, and also can store the corresponding relationship between the QFI and the QOS PROFI L ES in an AS layer.

In the embodiment of the present invention, the corresponding relationship between QFI and QOS PROFI L ES configured in the core network may be as shown in the following table 1:

QFI	QOS PROFILES
		QFI1	delay 30ms, rate 2M/S
QFI2	The packet loss rate is 10%
		……	……

TABLE 1

The following description, with reference to table 1, exemplifies a data transmission process performed by the sender and the receiver according to the corresponding relationship between QFI and QOS PROFI L ES:

for example, the sending end is a terminal, the terminal has a service request, the service requirement is a packet loss rate of 10%, the terminal determines that the QoS Profiles closest to the service requirement are a packet loss rate of 10% according to a correspondence between QFI and QoS Profiles configured in advance by the core network, the terminal determines QFI2 corresponding to the QoS Profiles, and the terminal sends a QoS flow data packet containing QFI2 to the network side device.

When the network side equipment receives a QoS flow data packet containing QFI2, the corresponding relation between QFI and QOS PROFI L ES determines that QoS Profiles corresponding to QFI2 are 10% of packet loss rate, and accordingly determines that QoS Profiles corresponding to the received QoS flow data packet are 10% of packet loss rate.
