Detailed ways

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

1) Network slicing

The network provides different NSSAIs for different UEs. One UE is configured with only one NSSAI information, and one NSSAI includes one or more Single-Network Slicing Selection Assistant Information (S-NSSAI). -NSSAI corresponds to a network slice.

In a 5G network, the terminal needs to go through the registration process to the 5G network to perform related 5G services. In the registration request message, the UE sends the requested S-NSSAI (Requested NSSAI) to the RAN and the AMF, and the AMF sends the Requested NSSAI to the Network Slice Selection Function (NSSF) to obtain the allowed S. -NSSAI (Allowed NSSAI), AMF sends the Allowed NSSAI back to the UE in the Registration Accept message. Here, the role of the NSSF is for other network elements (such as AMF) to enter the contracted NSSAI to get the Configured NSSAI and/or Allowed NSSAI for the UE.

The UE then carries the S-NSSAI (one of the Allowed NSSAIs) in the Protocol Data Unit (PDU) session request message, and the AMF on the network side queries the NSSF for the corresponding network slice temporary identifier according to the S-NSSAI carried by the UE. (NSI-ID, Network Slice Instance-ID), then the AMF sends the returned NSI-ID to the Network Repository Function (NRF), and the NRF returns the corresponding SMF (Session Management Function) network element information. The AMF finds the corresponding SMF network element through the information, and generates a corresponding PDU session, as shown in FIG. 2.

Here, NSSAI is divided into the following three types:

1, Requested NSSAI

It is sent in the UE registration request message, which information is used by the UE to apply for which S-NSSAI, and the RAN can also send the UE's non-access stratum (NAS) message to the specific AMF according to the information (AMF supporting Requested NSSAI) ).

2, Subscribed NSSAI

It is the NSSAI information that the network side subscribes to the user. When the NSSAI subscription information of the user changes, the UDM notifies the AMF to trigger the AMF to perform the NSSAI update configuration for the UE. Referring to FIG. 1, the core network sends a UE configuration update request to the UE. (UCU, UE Configuration Update) message, the UE sends a UE Configuration Update Request Reply (UCU Ack) message to the core network.

3, Allowed NSSAI

The AMF determines which is allowed to be used according to the NSSAI requested by the UE in the registration request message, and sends it back to the UE in the Registration Accept message in the Allowed NSSAI. The UE subsequently carries an S-NSSAI in the Allowed NSSAI in the PDU session setup request message to establish a corresponding PDU session.

As shown in FIG. 1 , in the UE configuration update request message (also referred to as UCU configuration information), the network side may carry the configured NSSAI configuration information (including Configured NSSAI, Mapping of Configured NSSAI, Allowed NSSAI, and Mapping of Allowed NSSAI). One or more), MICO configuration information (including MICO mode), initiation registration request indication (including "Registration is requested" indication).

After configuring the related information, the UE sends a UE configuration update request reply message to the core network.

The UE subsequently performs a re-registration process.

2) Registration process

Referring to FIG. 3, FIG. 3 is a registration flowchart of the UE. In the registration process, the Registration Request message includes the Requested NSSAI and the Registration Type=Initial/Update/Emergency. After receiving the Registration Request message, the RAN may determine according to the Requested NSSAI. Which AMF the NAS message of the UE is sent to.

Here, the UE registration process is started after the UE configuration process is completed, and is used in the following situations:

1. S-NSSAI parameter negotiation:

In the UE configuration process, after the UE receives the UCU configuration information (including the NSSAI configuration information) delivered by the network, the UE may initiate a registration request based on the Configured NSSAI. That is to say, the Requested NSSAI added by the UE in the registration request message is selected based on the Configured NSSAI. After receiving the message, the network side will return the Allowed NSSAI in the registration accept message, where the Allowed NSSAI is selected by the network side from the Requested NSSAI.

After the UE obtains the Allowed NSSAI, it uses it to initiate the establishment and/or modification process of the PDU session.

2. MICO mode negotiation:

When the UE is in the MCU (Mobile Initiated Connectivity Only) mode, it does not need to accept downlink signaling or data sent by any network side, and all signaling or data transmission needs to be initiated by the UE side.

In the UE configuration process, after receiving the UCU configuration information (including the MICO configuration information) sent by the network, the UE may initiate a registration request based on the new MICO parameter, and include a MICO preference parameter in the request message, and the network side is based on the parameter. And the rules on the network side determine whether to allow the UE to work in the MICO mode. If allowed, add "MICO mode" to the registration accept message, after which the UE will work in the MICO mode.

3. Replace the service network element (such as the current service AMF):

After the new parameters are sent to the UE, the currently serving NE may not be able to support the new parameters. In this case, the service network element (such as AMF) needs to be replaced. Therefore, a “registration is requested” indication may be added to the UCU configuration message, so that after receiving the configuration information, the UE may subsequently trigger the registration request according to the indication, and then replace the service network element (such as AMF) in the registration process.

3) Session establishment process

Referring to FIG. 4, FIG. 4 is a flowchart for establishing a session. In the session establishment process, when the UE sends a PDU session to establish a message, the S-NSSAI, DNN, Access Type, and PDU Session ID are reported to the network. The network thus establishes the required PDU Session for the UE based on the information.

In the above solution, after the UE obtains the UCU configuration information, the timing of the re-Registration is not strictly defined. Specifically, the “Registration is requested” is as follows: when the UCU configuration information includes “Registration is When requested, the UE needs to initiate a registration request when entering the CM-IDLE state. To this end, the network side may initiate a NAS or RRC signaling release connection to make the UE change to the CM-IDLE state. However, before the UE returns to the IDLE state, there is no guarantee that the UE will not trigger the registration process itself for other reasons, so it needs to be limited. In addition, when the newly configured parameters (such as Allowed NSSAI, Configured NSSAI) can be used or not, specifically: in the NSSAI configuration information, Configured NSSAI and Allowed NSSAI may not be used on the current service network element, and need to be After the NE is replaced, it can be used. Therefore, it needs to be qualified.

FIG. 5 is a schematic flowchart 1 of an information indication method according to an embodiment of the present disclosure. As shown in FIG. 5, the information indication method includes the following steps:

Step 501: The terminal receives the first UE configuration update message sent by the first core network element, where the first UE configuration update message includes at least one of the following: first NSSAI configuration information, initiation registration request indication information, and destination indication information. The destination indication information is used to indicate that the purpose of initiating the registration request is to replace the network element.

In the embodiment of the present application, the terminal may be any device capable of communicating with the network, such as a mobile phone, a tablet computer, a notebook computer, a desktop computer, and an in-vehicle terminal.

In the embodiment of the present application, the first core network element refers to the AMF, and the second core network element refers to the NSSF.

In the embodiment of the present application, the first UE configuration update message refers to the UE configuration update request message (also referred to as UCU configuration information) shown in FIG. 1 , and includes NSSAI configuration information (including Configured NSSAI, Mapping of Configured NSSAI, and Allowed NSSAI). , one or more of Mapping of Allowed NSSAI, MICO configuration information (including MICO mode), initiation registration request indication (including "Registration is requested" indication) information.

Step 502: The terminal determines, according to the first UE configuration update message, an opportunity to initiate a registration request and/or NSSAI configuration information that can be used and/or NSSAI configuration information that cannot be used.

In this embodiment, the terminal determines, according to the first UE configuration update message, the timing of initiating the registration request and/or the NSSAI configuration information that can be used and/or the NSSAI configuration information that cannot be used, and may be classified into the following two. Situation:

Case 1: The first UE configuration update message carries the first indication information, and the terminal determines, according to the first indication information, a timing of initiating the registration request and/or NSSAI configuration information that can be used and/or cannot be used. The NSSAI configuration information, specifically, the first indication information includes one or more of the following indication parameters:

Here, when the UE receives the first UE configuration update message, and the first indication information in the first UE configuration update message is the first indication parameter, the UE immediately performs a registration request in the connected state.

Here, in the case that the terminal receives the indication information of the initiation of the registration request before entering the idle state, when the terminal moves out of the specific registration area or the tracking area or the periodic location update timer expires, the The terminal performs a registration request process. Here, if the terminal receives the second indication parameter, even if it is not in an idle state, the registration request procedure is still executed when the terminal moves out of a specific registration area or tracking area or the periodic location update timer expires.

Case 2: The terminal determines the timing of initiating the registration request and/or the NSSAI configuration information that can be used and/or the NSSAI configuration information that cannot be used according to the parameters in the first UE configuration update message, where the following are specific Implementation:

1) If the first UE configuration update message includes the origination registration request indication information and/or the destination indication information, the terminal does not actively initiate a registration request before returning to the idle state, and/or The terminal does not use the first NSSAI configuration information.

2) If the first UE configuration update message includes the first NSSAI configuration information, and further includes the initiation registration request indication information and/or the destination indication information, the terminal determines the first core The network element does not support the first NSSAI configuration information, and the terminal does not use the first NSSAI configuration information before returning to the idle state, and does not initiate a registration request.

3) if the first UE configuration update message includes the first NSSAI configuration information, further including the initiation registration request indication information and/or an indication that the first NSSAI configuration information cannot be used before the registration request is completed The information is that the terminal determines that the first core network element does not support the first NSSAI configuration information, and the terminal does not use the first NSSAI configuration information before returning to the idle state, but uses the previously issued information. Second NSSAI configuration information. Further, the terminal does not initiate a registration request before returning to the idle state.

4) If the first UE configuration update message includes the first NSSAI configuration information but does not include the origination registration request indication information, the terminal determines that the first core network element supports the first NSSAI configuration information. The terminal immediately uses the first NSSAI configuration information.

In the above solution, the first NSSAI configuration information includes Configured NSSAI and/or Allowed NSSAI; wherein the Configured NSSAI includes one or more S-NSSAIs, and the Allowed NSSAI includes one or more S-NSSAIs.

In an embodiment, the Configured NSSAI and/or Allowed NSSAI in the first NSSAI configuration information is derived from the second core network element. Further, the first core network element sends a first request message to the second core network element, where the first request message is used to acquire Configured NSSAI and/or Allowed NSSAI of the terminal, where The first request message carries the second indication information, where the second indication information is used to indicate that the query purpose of the first request message is to initiate a UE configuration update. In an example, the second core network element sends a Configured NSSAI and/or an Allowed NSSAI supported by the first core network element of the terminal to the first core network element. In another example, the second core network element sends a Configured NSSAI and/or an Allowed NSSAI serving the terminal to the first core network element, where the first core network element supports itself. Configured NSSAI and/or Allowed NSSAI are sent to the terminal and carry the initiation registration request indication information. Here, the second core network element initiates a registration request at the terminal, and the core network element serving the terminal is sent to the third core network element by the first core network element. All Configured NSSAI and/or Allowed NSSAI of the first core network element are sent to the third core network element.

In a specific implementation, when the subscription NSSAI changes, the AMF carries the message “Query Purpose=Initiate UCU Configuration” (the message is used to obtain information about the Configured NSSAI and/or Allowed NSSAI used by the UE) when sending the message to the NSSF. The Configured NSSAI and/or Allowed NSSAI information returned by NSSF cannot be unsupported by the current AMF. That is, if the default UE can be used immediately for the newly acquired Allowed NSSAI, the NSSF cannot add the Allowed NSSAI currently serving the UE that is not supported in the Allowed NSSAI.
