In order to facilitate understanding of the technical solutions of the embodiments of the present application, the technical solutions related to the embodiments of the present application are described below.

A method for integrity protection of user plane data is introduced in the standard, and a terminal can report the maximum data rate capability of the characteristic (i.e. user plane integrity protection) supported by the terminal. The network side determines whether to start the user plane integrity protection function according to the maximum data rate capability supported by the terminal.

Standards specify a scenario for a specific network deployment, i.e. a scenario in which NR is connected to a 5G core network (5 GC) as a primary access type, and if the terminal supports this type of network deployment scenario, the terminal should set the maximum data rate capability of user plane integrity protection to Full rate (Full data rate). However, in an actual Network deployment scenario, there is a scenario in which NR and Evolved UMTS Terrestrial Radio Access Network (E-UTRAN) are mixed, for example, NR and E-UTRAN are both connected to 5GC, and in this Network deployment scenario, if a terminal can only report one maximum data rate capability (i.e., full rate) according to a current reporting mode, it cannot report different maximum data rate capabilities for different Network types (e.g., different RAT types). Therefore, the following technical scheme of the embodiment of the application is provided. The technical scheme of the embodiment of the application provides a mode for the terminal to distinguish different network types and report different terminal capabilities.

Fig. 2 is a schematic flowchart of a method for reporting terminal capability according to an embodiment of the present application, and as shown in fig. 2, the method for reporting terminal capability includes the following steps:

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

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

Here, different terminal capability information is distinguished for different core network types. For example: EPC (i.e., 4G core network) corresponds to terminal capability information 1,5gc (i.e., 5G core network) corresponds to terminal capability information 2.

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

Here, different terminal capability information is distinguished for different system types. For example: the EPS (i.e., 4G system) corresponds to the terminal capability information 1, and the 5gs (i.e., 5G system) corresponds to the terminal capability information 2.

In this embodiment, the terminal capability information may distinguish between an uplink and a downlink, and 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, and 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, which is shown in table 1 and table 2 below.

TABLE 1

TABLE 2

It should be noted that, in table 2, two pieces of terminal capability information are taken as an example, in the upper row, a value of 8 bits is 00000000 to represent terminal capability information 1, and a value of 8 bits is 11111111 to represent terminal capability information 2, where a maximum data rate capability of the terminal capability information 1 for indicating user plane integrity protection supported by the terminal is 64kbps, and a maximum data rate capability of the terminal capability information 2 for indicating user plane integrity protection supported by the terminal is a full rate, where the full rate refers to a maximum rate supported by the terminal itself.

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

Here, after the AMF forwards the first PDU session request message of the terminal to the SMF, the SMF determines whether to start a user plane integrity protection function for the current PDU session according to at least one piece of 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, a user plane integrity protection function is initiated 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 initiated for the current PDU session.

In one example, the SMF determines whether to start a user plane integrity protection function according to terminal capability information corresponding to a RAT type to which the terminal is currently accessing. For example: if the terminal is currently accessed to the NR, the SMF determines whether to start a user plane integrity protection function according to the terminal capability information 1 corresponding to the NR. For example: if the terminal is accessed to the E-UTRAN currently, the SMF determines whether to start the user plane integrity protection function according to the terminal capability information 2 corresponding to the E-UTRAN.

In the embodiment of the application, in the case that the SMF determines to initiate the user plane integrity protection function for the current PDU session,

1) In an optional manner, the SMF respectively issues each piece of terminal capability information in the at least one piece of terminal capability information to an access network corresponding to the terminal capability information, and performs an integrity protection function according to the terminal capability information through the access network.

For example: the at least one piece of terminal capability information comprises terminal capability information 1 and terminal capability information 2, the SMF issues the terminal capability information 1 to the NR, and issues the terminal capability information 2 to the E-UTRAN.

2) In another optional manner, the SMF issues a first terminal capability information of the at least one terminal capability information to an access network corresponding to the first terminal capability information, and performs an integrity protection function according to the first terminal capability information through the access network. Further, optionally, the first terminal capability information is terminal capability information corresponding to a first network type to which the terminal is currently accessed.

For example: the at least one terminal capability information includes terminal capability information 1 and terminal capability information 2. If the current access of the terminal is NR, the SMF sends the terminal capability information 1 to the NR. If the terminal is accessed to the E-UTRAN currently, the SMF sends the terminal capability information 2 to the E-UTRA.

In an optional embodiment of the present application, the first PDU session request message carries a plurality of 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 a first network type to which the terminal is currently accessed.

Further, when the terminal is switched from the first network type to the second network type, the terminal sends a second PDU session request message, and the network device receives the second PDU session request message, where the second PDU session request message carries second terminal capability information, and the second terminal capability information is terminal capability information corresponding to the second network type. Thus, updating of the terminal capability information can be achieved.

In one example, the terminal carries terminal capability information corresponding to the currently camped network type in the PDU establishing session request message, for example, if the terminal is camped on NR, then terminal capability information 1 corresponding to NR is carried. After receiving the terminal capability information 1, the SMF determines whether to start 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 start the integrity protection function according to the terminal capability information 2.

Fig. 3 is a schematic diagram of a PDU session establishment procedure provided in an embodiment of the present application, and as shown in fig. 3, in step 1, a terminal carries at least one piece of terminal capability information in a PDU session establishment request message. In step 3, the AMF forwards the PDU session setup request message of the terminal to the SMF. In step 11, the SMF determines whether to initiate a user plane integrity protection function for the current PDU session according to the terminal capability information.

In an optional manner, the first PDU session request message carries multiple pieces of terminal capability information.
