In an embodiment, a network entity running a policy control function (PCF), may send to a wireless receive and transmit unit (WTRU) at least one WTRU route selection policy (URSP) rule associated with, for example, PvD descriptors. For example, URSP rules may be configured e.g., as part of the subscription profile and PvD descriptors may be configured e.g., as part of a network-wide configuration. An application function (AF) may use a network exposure function (NEF) application programming interface (API) to access and, for example, update, e.g. through any of NEF and PCF, any of URSP rules and PvD descriptors. According to embodiments, a WTRU may participate in a data network access identifier (DNAI) selection by including a PvD ID in, for example, PDU session establishment messages. ## Claims ### Claim 1 A method implemented in a wireless transmit/receive unit (WTRU) the method comprising: receiving configuration information indicating at least one WTRU route selection policy (URSP) rule and at least one provisioning domain descriptor, wherein the at least one URSP rule indicates at least one provisioning domain identifier (PvD ID) of a plurality of PvD IDs; selecting a PvD ID from the plurality of PvD IDs based on the at least one provisioning domain descriptor, wherein the at least one provisioning domain descriptor comprises at least one attribute of a new or previously used provisioning domain, and wherein selecting the PvD ID comprises selecting the PvD ID based on the at least one attribute of the new or previously used provisioning domain; transmitting a session establishment request message including information indicating the selected PvD ID; and receiving a session establishment accept message indicating that a session is established between the WTRU and a network function associated with the selected PvD ID. ### Claim 2 (depends on 1) The method of claim 1, wherein selecting the PvD ID comprises selecting the PvD ID by an application running on the WTRU. ### Claim 3 (depends on 1) The method of claim 1, wherein the at least one provisioning domain descriptor indicates a data network access identifier associated with the selected PvD ID. ### Claim 4 (depends on 1) The method of claim 1, wherein the network function associated with the selected PvD ID comprises a user plane function (UPF) collocated with a data network access point identified by a data network access identifier associated with the selected PvD ID. ### Claim 5 (depends on 1) The method according to claim 1, wherein the session establishment request message is for requesting a selection of a data network access identifier associated with the selected PvD ID. ### Claim 6 A wireless transmit/receive unit (WTRU) comprising circuitry, including any of a transmitter, receiver, processor and memory, the WTRU being configured to: receive configuration information indicating at least one WTRU route selection policy (URSP) rule and at least one provisioning domain descriptor, wherein the at least one URSP rule indicates at least one provisioning domain identifier (PvD ID) of a plurality of PvD IDs; select a PvD ID from the plurality of PvD IDs based on the at least one provisioning domain descriptor, wherein the at least one provisioning domain descriptor comprises at least one attribute of a new or previously used provisioning domain, and wherein being configured to select the PvD ID comprises being configured to select the PvD ID based on the at least one attribute of the new or previously used provisioning domain; transmit a session establishment request message including information indicating the selected PvD ID; and receive a session establishment accept message indicating that a session is established between the WTRU and a network function associated with the selected PvD ID. ### Claim 7 (depends on 6) The WTRU of claim 6, wherein being configured to select the PvD ID comprises being configured to select the PvD ID by an application running on the WTRU. ### Claim 8 (depends on 6) The WTRU of claim 6, wherein the at least one provisioning domain descriptor indicates a data network access identifier associated with the selected PvD ID. ### Claim 9 (depends on 6) The WTRU of claim 6, wherein the network function associated with the selected PvD ID comprises a user plane function (UPF) collocated with a data network access point identified by a data network access identifier associated with the selected PvD ID. ### Claim 10 (depends on 6) The WTRU of claim 6, wherein the session establishment request message is for requesting a selection of a data network access identifier associated with the selected PvD ID. ### Claim 11 (depends on 1) The method of claim 1, wherein the at least one provisioning domain descriptor indicates at least one provisioning domain, and wherein a first provisioning domain is associated with network configuration information to be used for connecting to a network of a plurality of networks. ### Claim 12 (depends on 1) The method of claim 1, wherein the configuration information indicates a plurality of URSP rules and wherein a URSP rule is selected from the plurality of URSP rules based on the selected PvD ID. ### Claim 13 (depends on 1) The method of claim 1, wherein the session establishment request message is a protocol data unit (PDU) session establishment request message. ### Claim 14 (depends on 6) The WTRU of claim 6, wherein the at least one provisioning domain descriptor indicates at least one provisioning domain, and wherein a first provisioning domain is associated with network configuration information to be used for connecting to a network of a plurality of networks. ### Claim 15 (depends on 6) The WTRU of claim 6, wherein the configuration information indicates a plurality of URSP rules and wherein a URSP rule is selected from the plurality of URSP rules based on the selected PvD ID. ### Claim 16 (depends on 6) The WTRU of claim 6, wherein the session establishment request message is a protocol data unit (PDU) session establishment request message.
