[0082] Optionall...
Embodiment 2
[0116] In this embodiment, the terminal can assign matching values to each service, and of course, the network can modify some of the matching values, such as image 3 Shown, this embodiment comprises the following steps:
[0117] Step 301: The terminal sends a service configuration request message to the AMF through a NAS message, such as sending a UL NASmessage or Registration Request message, and the service configuration request message can carry one or more matching relationships, such as policy (Policy) matching relationship or cause (Cause) matching relation.
[0118] The matching relationship above includes at least a matching value (for example, a policy identifier in the policy matching information, and a cause value in the cause matching information), and one or more service information / service type information corresponding to the matching value.
[0119] In the following, the matching relationship includes a matching value and one or more business information c...

[0145] This embodiment mainly embodies the role of policy matching information, such as Figure 4 Shown, this embodiment comprises the following steps:
[0146] Step 401: Steps 201-202 of Embodiment 1 or Steps 301-302 of Embodiment 2 are used to complete the process of negotiating policy matching information between the terminal and the AMF.
[0147] Step 402: Optionally, the terminal notifies the AMF of the service information of another USIM that is currently active, such as sending a UL NAS message carrying the service information. In this embodiment, the terminal may have multiple USIMs installed.
[0148] Step 403: at a later time, the application server sends application data to the terminal.
[0149] Step 404: The application data arrives at the UPF, and the UPF sends a downlink data notification, such as a DL data Notify message, to the SMF.
[0150] The downlink data notification can carry the application identifier identified by the UPF, or the UPF matches the rec...
