Abstract

Methods, apparatuses, systems, etc., directed to support provisioning domains (PvDs) in 5G networks are disclosed herein. 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 (15)

  1. A method implemented in a network element, the method comprising: receiving, from an application function, AF, a request to associate a provisioning domain, PvD, identifier, PvD ID, with at least one association parameter; identifying a wireless transmit/receive unit, WTRU, route selection policy, URSP, rule corresponding to the association parameter, modifying the URSP rule by inserting the PvD ID into at least one of a traffic descriptor section and a route selection section of the URSP rule; and sending a message to a data repository to store the URSP rule.
  2. The method of claim 1, wherein identifying the URSP rule comprises creating the URSP rule based on the at least one association parameter.
  3. The method of any of claims 1 to 2, wherein the at least one association parameter comprises at least one of: (i) a WTRU identifier, (ii) a WTRU group identifier, (iii) a data network name, DNN, (iv) a data network access identifier, DNAI, (v) a network slice identifier, (vi) a protocol data unit, PDU, session type, (vii) an application identifier, or (viii) a domain name.
  4. The method of any of claims 1 to 3, wherein receiving the request from the AF comprises receiving an AF transaction identifier for at least one of referencing, updating, or deleting the association of the PvD ID with the at least one association parameter.
  5. The method of any of claims 1 to 4, wherein sending the message to the data repository comprises transmitting a policy update message identifying the URSP rule and the PvD ID.
  6. The method of any of claims 1 to 5, further comprising sending the URSP rule to a policy control function, PCF, for delivery to the WTRU.
  7. The method of any of claims 1 to 6, further comprising receiving, from the AF, a request to modify one or more PvD attributes associated with the PvD ID.
  8. A network element comprising circuitry including a transmitter, a receiver, a processor and memory configured to: receive, from an application function, AF, a request to associate a provisioning domain, PvD, identifier, PvD ID, with at least one association parameter; identify a wireless transmit/receive unit, WTRU, route selection policy, URSP, rule corresponding to the association parameter, modify the URSP rule by inserting the PvD ID into at least one of a traffic descriptor section and a route selection section of the URSP rule; and send a message to a data repository to store the URSP rule.
  9. The network element of claim 8, wherein being configured to identify the URSP rule comprises being configured to create the URSP rule based on the at least one association parameter.
  10. The network element of any of claims 8 to 9, wherein the at least one association parameter comprises at least one of: (i) a WTRU identifier, (ii) a WTRU group identifier, (iii) a data network name, DNN, (iv) a data network access identifier, DNAI, (v) a network slice identifier, (vi) a protocol data unit, PDU, session type, (vii) an application identifier, or (viii) a domain name.
  11. The network element of any of claims 8 to 10, wherein being configured to receive the request from the AF comprises being configured to receive an AF transaction identifier for at least one of referencing, updating, or deleting the association of the PvD ID with the at least one association parameter.
  12. The network element of any of claims 8 to 11, wherein being configured to send the message to the data repository comprises being configured to transmit a policy update message identifying the URSP rule and the PvD ID.
  13. The network element of any of claims 8 to 12, configured to send the URSP rule to a policy control function, PCF, for delivery to the WTRU.
  14. The network element of any of claims 8 to 13, configured to receive, from the AF, a request to modify one or more PvD attributes associated with the PvD ID.
  15. The network element of any of claims 8 to 14, comprising a network exposure function, NEF.
