FIG. 3 is a flowchart of a method for sending data according to an embodiment of the present invention. As shown in FIG. 3, the method includes the following steps:

Step S301: The gateway user plane module sets a data label for the downlink data packet to be sent, and the data label is used to identify the session to which the downlink data packet belongs.

Step S302: The gateway user plane module sends a downlink data packet carrying the data label to the user terminal, and the network element between the gateway user plane module and the user terminal forwards the downlink data packet based on the data label.

Before step S301, the gateway user plane module receives the data label generated by the session control plane module based on the intermediate information; wherein the intermediate information is related to one or more of the session, the network slice where the session is located, and the quality of service corresponding to the downlink data packet. The gateway user plane module and the session control plane module are set in the network slice.

In an embodiment of the present invention, the intermediate information includes a first label and a second label, wherein the first label is a label allocated by the common control plane module, the second label is a label allocated by the session control plane module, and the common control plane module is configured. On the core network.

It should be noted that, in the case that multiple session control plane modules exist in the network slice, the first label is used to identify the network slice and the session, and the second label is used to identify the quality of service parameter corresponding to the downlink data packet; In the case where only one session control plane module exists, the first label is used to identify the network slice, and the second label is used to identify the session and the service corresponding to the downlink data packet. Quality parameters.

Specifically, before the gateway user plane module determines the data label to be set to the downlink data packet based on the intermediate information, the session control plane module generates the data label by receiving the first label sent by the common control plane module, and the downlink data. The packet is assigned a second label; the data label to be set to the downlink data packet is determined based on the intermediate information, that is, the data label including the first label and the second label is generated; or the data label including the identifier of the session and the second label is generated.

The embodiment of the present application is described in detail below with reference to FIG. 4, and the QoS label (ie, the data label) is allocated by the session control plane function (ie, the session control plane anchor function, that is, the session control plane module), and the QoS label can be unique in the user context. Identify the slice, session, and corresponding QoS parameters for the data. Specifically, as shown in Figure 4:

In step S401, the terminal initiates a registration process to the public control plane function. In the process, the base station selects a suitable common control plane function and sends the registration message to the public control plane function. The public control plane function needs to authenticate the user, obtain the user subscription information from the home network, and allocate the user registration location list and A temporary user ID is sent to the terminal in the registration response. When the terminal accesses, the public control plane function of the previous service and the user context therein can be found according to the temporary user identifier.

Step S402, the terminal initiates a setup PDU session request to the common control plane function, where the message carries the user temporary identifier, the slice selection auxiliary information, and the session-related information, such as an access point name (APN, Access Point Name) and a session. Type (indicating IPv4, IPv6, IPv4v6, or non-IP). The slice selection assistance information may include information such as the requested slice type, tenant identification, and the like.

Step S403, the public control plane function first finds the user context according to the temporary identifier of the user, and then selects an appropriate network slice instance according to the slice selection auxiliary information and the user subscription information provided by the terminal, and selects an appropriate one in the selected network slice instance. The session control plane function then sends a setup PDU session request to the selected session control plane function. The common control plane function assigns a first tag and sends the first tag to the selected session control plane function.

Step S404, a session request process is created, and the session control plane function creates a user session context. According to the session related information, select the appropriate gateway user plane function, and then initiate a session creation process to the gateway control plane function. The gateway user plane function assigns session-related tunnel information and returns it to the session control plane function. In the process, the session control plane function determines the QoS parameters (ie, quality of service parameters) allowed for the session according to the user subscription and the operator policy, and allocates corresponding QoS labels, and the generated QoS label can be uniquely identified in the user context. A set of QoS parameters in the session context within the selected slice. There are several ways to assign QoS labels:

For a scenario in which a user has only one session control plane function in a slice, the first label uniquely identifies the slice instance, and the session control plane performs a second label, the label identifies the session within the slice, and uniquely identifies each session in the session context. The group QoS parameter, the session control plane function generates a QoS label according to the first label and the second label generated by itself;

For a scenario in which a user has multiple session control plane functions within a slice, the first tag can uniquely identify the slice instance (ie, the network slice) and the requested session, and the session control plane function assigns a second label that identifies the session. Each QoS parameter is uniquely identified in the context, and the session control plane function generates a QoS label according to the first label and the second label generated by itself;

For a scenario where a user has only one session control plane function in one slice, and the first label is not received from the common control plane function, the session control plane function allocates a second label, which can uniquely identify the session within the slice. And each group of QoS parameters in the session, the session control plane function generates a QoS label according to the unique slice instance identifier of the entire network and the second label generated by itself.

Step S405: According to the service requirement and the operator policy, the session control plane function may need to request the base station to allocate a new radio resource, and then initiate a radio resource allocation request to the common control plane function, where the session related information, including the QoS label and the corresponding QoS parameters, and session-related tunnel information for gateway user plane functions.

Step S406, the public control plane function forwards the radio resource allocation request to the base station. If this is When the first PDU session of the terminal is established, the common control plane function may also send other user related information to the base station, such as security related key and terminal capability.

Step S407: The base station saves the session related information, including the user's session context, security context, terminal capability information, and the like, and interacts with the UE to update or create a related radio resource. The base station allocates session related tunnel information and returns a radio resource allocation response message of the common control plane function.

Step S408, the common control plane function returns a radio resource allocation response message to the session control plane function, where the session-related tunnel information allocated by the base station is carried.

Step S409, the session request process is updated, and the session control plane function sends the session-related tunnel information allocated by the base station to the gateway user plane function. Thereby, a session-related tunnel between the base station and the gateway user plane function is established.

Step S410: The session control plane function sends a setup PDU session response to the common control plane function, where the session related information is included, including the QoS label and the corresponding QoS parameter. The QoS parameter includes an uplink data classifier, and the terminal determines the QoS label required by the data packet according to the uplink data classifier. The uplink data classifier may include IP layer 5-tuple information with user data, or specific application identification information, or specific service type information.

Step S411, the common control plane function sends a setup PDU session response to the UE, where the session related information is included, including the QoS label and the corresponding QoS parameter. It should be noted that although the UE knows the QoS label of the session, it does not mean that the terminal needs to know that the network has deployed the network slice.

Step S412, the PDU session between the UE and the gateway user plane function is established through the foregoing process, and the IP address allocation process can be performed between the UE and the gateway user plane function through a Dynamic Host Configuration Protocol (DHCP). The UE can then send and receive data through the PDU session.

According to an embodiment of the present invention, a method embodiment of a method for sending data is also provided, FIG. 5 Is a flowchart of another method for sending data according to an embodiment of the present invention. As shown in FIG. 5, the method includes the following steps:

Step S501: The user terminal sets a data label for the uplink data packet to be sent, where the data label is used to identify the session to which the uplink data packet belongs.

Step S502: The user terminal sends an uplink data packet carrying the data label to the gateway user plane module, and the network element between the user terminal and the gateway user plane module forwards the uplink data packet based on the data label.

In step S501, the user terminal setting the data label for the uplink data packet to be sent includes: determining, by the user terminal, the data label to be set to the uplink data packet based on the intermediate information, where the intermediate information is segmented by the session, the network segment where the session is located, and the uplink One or more of the service quality parameters corresponding to the data packet are determined, and a gateway user plane module is set in the network slice; the user terminal sets the data label to the uplink data packet.

It should be noted that before the user terminal determines the data label to be set to the uplink data packet based on the intermediate information, the user terminal receives the data label generated by the session control plane module based on the intermediate information, where the intermediate information and the session and the network slice where the session is located And related to one or more of the quality of service corresponding to the uplink data packet, the gateway user plane module and the session control plane module are set in the network slice.

In the case that there are multiple session control plane modules in the network slice, the first label is used to identify the network slice and the session, and the second label is used to identify the quality of service parameter corresponding to the uplink data packet; there is only one session in the network slice. In the case of the control plane module (ie, the session control plane module), the first label is used to identify the network slice, and the second label is used to identify the session and the quality of service parameter corresponding to the uplink data packet.

The embodiment of the present application is described in detail below with reference to FIG. 6, and the common control plane functions to assign the first label and Sended to the base station and the terminal, the session control plane function allocates a second label and sends it to the base station and the terminal. The QoS label of the terminal uplink data is composed of a first label and a second label. Specifically, as shown in Figure 6:

In step S601, the terminal initiates a registration process to the public control plane function. In the process, the base station selects a suitable common control plane function and sends the registration message to the public control plane function. The public control plane function needs to authenticate the user, obtain the user subscription information from the home network, and allocate the user registration location list and A temporary user ID is sent to the terminal in the registration response. When the terminal accesses, the public control plane function of the previous service and the user context therein can be found according to the temporary user identifier.

Step S602, the terminal initiates a PDU session request to the public control plane function, where the message carries the user temporary identifier, the slice selection auxiliary information, and the session-related information such as the APN and the session type (indicating IPv4, IPv6, IPv4v6, or non- IP). The slice selection assistance information may include information such as the requested slice type, tenant identification, and the like.

Step S603, the public control plane function first finds the user context according to the temporary identifier of the user, and then selects an appropriate network slice instance according to the slice selection auxiliary information and the user subscription information provided by the terminal, and selects an appropriate one in the selected network slice instance. The session control plane function then sends a setup PDU session request to the selected session control plane function. The common control plane function assigns the first label.

Step S604, a session request process is created, and the session control plane function creates a user session context. According to the session related information, select the appropriate gateway user plane function, and then initiate a session creation process to the gateway control plane function. The gateway user plane function assigns session-related tunnel information and returns it to the session control plane function. In this process, the session control plane function determines the QoS parameters allowed for the session according to the user subscription and the operator policy, and assigns a corresponding second label. The second label is assigned in the following ways:

For a scenario where a user has only one session control plane function within a slice, the first standard Signing a unique identification slice instance, the second tag can uniquely identify the session within the slice, and uniquely identifies each set of QoS parameters in the session context;

For a scenario where a user has multiple session control plane functions within a slice, the first tag needs to uniquely identify the slice instance and the session, and the second tag uniquely identifies each set of QoS parameters in the session context.

Step S605, according to the service requirement and the operator policy, the session control plane function may need to request the base station to allocate a new radio resource, and then initiate a radio resource allocation request to the common control plane function, where the session related information, including the second label and corresponding QoS parameters, as well as session-related tunnel information for gateway user plane functions.

Step S606, the public control plane function sends a radio resource allocation request to the base station. If this is the first PDU session establishment of the terminal, the common control plane function may also send other user related information to the base station, such as security related key, terminal capability and the like. The common control plane function also carries the first tag information assigned to the session in the message.

Step S607: The base station saves the session related information, including the first label and the second label information of the user, the session context, the security context, the terminal capability information, and the like, and interacts with the UE to update or create a new related radio resource. The base station allocates session related tunnel information and returns a common control plane function radio resource allocation response message.

Step S608, the common control plane function returns a radio resource allocation response message to the session control plane function, where the session-related tunnel information allocated by the base station is carried.

Step S609, the session request process is updated, and the session control plane function sends the session-related tunnel information allocated by the base station to the gateway user plane function. Thereby, a session-related tunnel between the base station and the gateway user plane function is established.

Step S610, the session control plane function sends a setup PDU session response to the common control plane function, where the session related information is included, including the second label and the corresponding QoS parameter. The QoS parameter includes an uplink data classifier, and the terminal determines the data packet according to the uplink data classifier. QoS label. The uplink data classifier may include IP layer 5-tuple information with user data, or specific application identification information, or specific service type information.

Step S611, the common control plane function sends a setup PDU session response to the UE, where the session related information is included, including the second label and the corresponding QoS parameter. The common control plane function also carries the first tag information assigned to the session in the message.

Step S612, through the foregoing process, a PDU session between the UE and the gateway user plane function is established, and an IP address allocation process can be performed between the UE and the gateway user plane function through DHCP. The UE can then send and receive data through the PDU session. The terminal carries the QoS label in the uplink data, where the first label and the second label are received from the network side, and the base station can uniquely determine the slice instance corresponding to the data packet according to the first label and the second label, and corresponding Conversation.

In the above embodiment, a QoS label is placed outside all packets between the terminal and the gateway user plane function. For downlink data, the gateway user plane anchor function puts a corresponding QoS label on the outside of the data packet according to the QoS requirements of each packet in the service data stream. For the uplink data, the terminal puts corresponding QoS label data on the outside of the data packet according to the data flow template or the application related information. Other user plane functions between the terminal and gateway user plane functions forward the data based on the QoS label. At the base station, the QoS requirements required by the data packet need to be determined according to the QoS label and processed. Through the scheme of the QoS label of the user plane of the present application, the problem that the data packet in one service data flow may require different QoS processing is solved.

FIG. 7 is a schematic diagram of a process of transmitting uplink data by a user plane.

Step S701: When the terminal needs to send the uplink data, according to the uplink data classifier received from the network side, determine the QoS label (that is, the data label) required by the data (that is, the uplink data), and add the QoS label to the uplink. In the header of the data, it is sent to the base station.

Step S702: The base station first determines, according to the saved user context, the slice of the QoS label and the corresponding session according to the QoS label, determines a tunnel to the gateway user plane function of the session, and then sends the uplink data with the QoS label from the tunnel. Forward to the corresponding gateway user plane function. The above data is sent to the gateway user plane function 1 or the gateway user plane function 2.

Through this scheme, the base station does not need to check the source address and the destination address of the data packet, thereby reducing the processing delay, and the scheme can also be applied to the transmission of non-IP data packets at the same time.

It should be noted that, for the downlink data, the processing procedure is similar, and details are not described herein again.
