The standard introduces a method for integrity protection of user plane data, and a terminal can report the maximum data rate capability of this feature (ie, user plane integrity protection) that it supports. The network side determines whether to activate the user plane integrity protection function according to the maximum data rate capability supported by the terminal.

The standard has formulated for a specific network deployment scenario, that is, the scenario where NR is used as the main access type to connect to the 5G core network (5GC). If the terminal supports this type of network deployment scenario, the terminal should protect the integrity of the user plane to the maximum extent possible. The data rate capability is set to Full data rate. However, in actual network deployment scenarios, there is a mixed network deployment scenario of NR and Evolved UMTS Terrestrial Radio Access Network (E-UTRAN). For example, both NR and E-UTRAN are connected to 5GC. In this network deployment scenario, if the terminal can only report one maximum data rate capability (that is, full rate) according to the current reporting method, it cannot report different maximum data rate capabilities for different network types (such as different RAT types). . To this end, the following technical solutions of the embodiments of the present application are proposed. The technical solutions of the embodiments of the present application propose a method for a terminal to report different terminal capabilities by distinguishing different network types.

FIG. 2 is a schematic flowchart of a method for reporting terminal capabilities provided by an embodiment of the present application. As shown in FIG. 2 , the method for reporting terminal capabilities includes the following steps:

Step 201: The terminal sends a first PDU session request message, and the network device receives the first PDU session request message, where the first PDU session request message carries at least one terminal capability information, and the terminal capability information is used to indicate the The maximum data rate capability of user plane integrity protection; wherein, each terminal capability information in the at least one terminal capability information has a corresponding relationship with a network type.

In this embodiment of the present application, the first PDU session request message may be a PDU session establishment request message. Alternatively, the first PDU session request message may be a PDU session modification request message.

In this embodiment of the present application, the first PDU session request message carries at least one terminal capability information, where the terminal capability information is used to indicate the maximum data rate capability of the user plane integrity protection supported by the terminal; wherein the at least one Each terminal capability information in a terminal capability information has a corresponding relationship with a network type.

● In an optional manner, the network type is a radio access technology (Radio Access Technology, RAT) type, and each terminal capability information in the at least one terminal capability information has a corresponding relationship with a RAT type.

Here, different terminal capability information is distinguished for different RAT types. For example, NR corresponds to terminal capability information 1, and E-UTRAN corresponds to terminal capability information 2.

● In an optional manner, the network type is a core network type, and each terminal capability information in the at least one terminal capability information has a corresponding relationship with a core network type.

Here, different terminal capability information is distinguished for different core network types. For example, EPC (ie 4G core network) corresponds to terminal capability information 1, and 5GC (ie 5G core network) corresponds to terminal capability information 2.

● In an optional manner, the network type is a system type, and each terminal capability information in the at least one terminal capability information has a corresponding relationship with a system type.

Here, different terminal capability information is distinguished for different system types. For example, EPS (ie, 4G system) corresponds to terminal capability information 1, and 5GS (ie, 5G system) corresponds to terminal capability information 2.

In this embodiment of the present application, the terminal capability information may distinguish the uplink and the downlink. Specifically, for the uplink, the terminal capability information is used to indicate the maximum data rate capability of the user plane integrity protection supported by the uplink terminal. For the downlink, The terminal capability information is used to indicate the maximum data rate capability of the user plane integrity protection supported by the downlink terminal, as shown in Table 1 and Table 2 below.

Table 1

Table 2

It should be noted that Table 2 takes two terminal capability information as an example. For the above line, the value of 8 bits is 00000000 to represent terminal capability information 1, and the value of 8 bits is 11111111 to represent terminal capability information 2. , where the terminal capability information 1 is used to indicate that the maximum data rate capability of the user plane integrity protection supported by the terminal is 64kbps, and the terminal capability information 2 is used to indicate that the maximum data rate capability of the user plane integrity protection supported by the terminal is full rate, Here, the full rate refers to the maximum rate supported by the terminal itself.

In this embodiment of the present application, the terminal sends a first PDU session request message to an access and mobility management function network element (Access and Mobility Management Function, AMF), and the first PDU session request message is forwarded by the AMF to A session management function network element (Session Management Function, SMF); correspondingly, the SMF receives the first PDU session request message from the terminal forwarded by the AMF; wherein, the at least one terminal capability carried in the first PDU session request message The information is used by the SMF to determine whether to enable the user plane integrity protection function.

Here, after the AMF forwards the terminal's first PDU session request message to the SMF, the SMF determines whether to enable the user plane integrity protection function for the current PDU session according to at least one terminal capability information carried in the first PDU session request message. Specifically, if the terminal capability information supports the data rate of the current PDU session, the user plane integrity protection function is activated for the current PDU session. If the terminal capability information does not support the data rate of the current PDU session, the user plane integrity protection function is not activated for the current PDU session.

In an example, the SMF determines whether to activate the user plane integrity protection function according to the terminal capability information corresponding to the RAT type currently accessed by the terminal. For example, if the terminal currently accesses an NR, the SMF determines whether to activate the user plane integrity protection function according to the terminal capability information 1 corresponding to the NR. For example, if the terminal is currently accessing the E-UTRAN, the SMF determines whether to activate the user plane integrity protection function according to the terminal capability information 2 corresponding to the E-UTRAN.

In this embodiment of the present application, when the SMF determines to enable the user plane integrity protection function for the current PDU session,

1) In an optional manner, the SMF delivers each terminal capability information in the at least one terminal capability information to the access network corresponding to the terminal capability information, and the access network sends the information to the access network according to the The terminal capability information performs the integrity protection function.

For example, the at least one terminal capability information includes terminal capability information 1 and terminal capability information 2, and the SMF delivers the terminal capability information 1 to the NR, and delivers the terminal capability information 2 to the E-UTRAN.

2) In another optional manner, the SMF delivers the first terminal capability information in the at least one terminal capability information to the access network corresponding to the first terminal capability information, and sends the first terminal capability information through the access network. The integrity protection function is performed according to the first terminal capability information. Further, optionally, the first terminal capability information is terminal capability information corresponding to the first network type currently accessed by the terminal.

For example, the at least one terminal capability information includes terminal capability information 1 and terminal capability information 2. If the terminal is currently accessing the NR, the SMF sends the terminal capability information 1 to the NR. If the terminal is currently accessing the E-UTRAN, the SMF delivers the terminal capability information 2 to the E-UTRA.

In an optional embodiment of the present application, the first PDU session request message carries multiple terminal capability information.

In an optional embodiment of the present application, the first PDU session request message carries first terminal capability information, where the first terminal capability information is terminal capability information corresponding to the first network type currently accessed by the terminal.

Further, when the terminal switches from the first network type to the second network type, the terminal sends a second PDU session request message, the network device receives a second PDU session request message, the second PDU session request message The message carries second terminal capability information, where the second terminal capability information is terminal capability information corresponding to the second network type. In this way, the update of the terminal capability information can be realized.

In an example, the terminal carries the terminal capability information corresponding to the currently residing network type in the PDU session establishment request message. For example, if the terminal resides in an NR, the terminal capability information 1 corresponding to the NR is carried. After receiving the terminal capability information 1, the SMF determines whether to activate the integrity protection function according to the terminal capability information 1. When the terminal moves from the NR to another network, for example, to the E-UTRAN, the terminal initiates a PDU session modification request, and the PDU session modification request message carries the terminal capability information 2 corresponding to the E-UTRAN. After receiving the terminal capability information 2, the SMF updates the original terminal capability information 1 to the terminal capability information 2, and determines whether to activate the integrity protection function according to the terminal capability information 2.

As shown in FIG. 3 , in step 1, a terminal carries at least one terminal capability information in a PDU session establishment request message. In step 3, the AMF forwards the PDU session establishment request message of the terminal to the SMF. In step 11, the SMF determines whether to activate the user plane integrity protection function for the current PDU session according to the terminal capability information.
