[0002] In a dual steering scenario, there are multiple available accesses, for example, including one non-3GPP access and one or more 3GPP accesses, or including multiple 3GPP accesses.

[0164] Embodiment 1

[0165] In this embodiment, the UE receives a first policy sent by a first network, and performs a first operation based on the first policy. The embodiment includes the following steps:

[0166] Step 1: UE establishes multiple access or multiple connections with AMF or SMF, such as sending a NAS protocol registration message to AMF through different accesses (non-3GPP+3GPP or 3GPP+3GPP) (NAS protocol messages on a certain access may be converged to the same AMF through the forwarding of the intermediate AMF, or it may be different AMFs), or sending PDU session (PDU Session) related operation information to SMF through AMF, such as PDU Session establishment or update information (PDUSession related operation information on a certain access may be converged to the same SMF through the forwarding of the intermediate AMF and / or SMF, or it may be different SMFs).

[0167] The UE may indicate support for multiple access and / or multiple connections (corresponding to the policy assistance information of the previous embodiment) in a message sent to the AMF or SMF. The indication information may be included in the above-mentioned message (for example, carried by one access message, or carried by multiple access messages respectively), or may be carried by a separate message (for example, carried by one access message, or carried by multiple access messages respectively).

[0168] Step 2: AMF or SMF can interact with PCF to obtain the UE's policy assistance information, which can carry information that the UE supports multiple access and / or multiple connections.

[0169] Step 3: PCF can obtain the UE's subscription information from UDM, including the UE's multi-access or multi-connection subscription information; PCF, AMF, and SMF send corresponding multi-access and / or multi-connection policies to the UE (PCF sends to the UE through AMF or SMF) based on the received multi-access and / or multi-connection support information, and / or the UE's multi-access and / or multi-connection subscription information returned by UDM. The multi-access and / or multi-connection policy corresponds to the first policy in the previous embodiment.
