Abstract
Systems, methods, and instrumentalities are disclosed for enforcing limited mobility in a mobile network. For example, a wireless transmit/receive unit (WTRU) may receive (e.g., receive from a network) a mapping of physical cell identifications (PCIs) to area identifications (AIDs). The WTRU may determine a first PCI associated with a first neighbor cell. The WTRU may determine, based on the first PCI and the PCIs to AIDs mapping, whether the WTRU is allowed to access the first neighbor cell. The WTRU may perform cell selection or reselection with the first neighbor cell as a cell selection or reselection candidate. The WTRU may perform cell selection or reselection based on the WTRU determining that the WTRU is allowed to access the first neighbor cell. The WTRU may determine that the WTRU is allowed to access the first neighbor cell based on the first PCI and the PCIs to AIDs mapping.

Claim
1-15. (canceled)
16. A network node comprising:
a processor configured to:
receive a first request message from a wireless transmit/receive unit (WTRU), the first request message comprising an indication to establish a user plane;
determine whether the WTRU is located in an allowed area or a non-allowed area; and
based on a determination that the WTRU is in the non-allowed area, send a first response message to the first request message, the first response message indicating that the WTRU is located in a non-allowed area and that the WTRU is not allowed to send a request to establish the user plane in the non-allowed area.
17. The network node of claim 16, wherein the processor is configured to:
receive a second request message from the WTRU without the indication to establish the user plane.
18. The network node of claim 16, wherein the processor is configured to:
update a tracking area list (TAU) associated with a location of the WTRU based on the determination that the WTRU is in the allowed area or the non-allowed area.
19. The network node of claim 16, wherein the processor is configured to:
determine whether a location of the WTRU has been changed; based on a determination that the location of the WTRU has been changed, determine whether the changed location of the WTRU is in the allowed area or the non-allowed area; on a condition that the changed location of the WTRU is in the allowed area, send a second response message to the WTRU indicating that the WTRU is located in the allowed area and that the WTRU is allowed to send the request to establish the user plane; and on a condition that the changed location of the WTRU is in the non-allowed area, send the second response message to the WTRU indicating that the WTRU is located in the non-allowed area and that the WTRU is not allowed to send the request to establish the user plane in the non-allowed area.
20. The network node of claim 19, wherein the processor is configured to:
receive a second request message from the WTRU without the indication to establish the user plane based on the second response message.
21. The network node of claim 19, wherein the processor is configured to:
receive a second request message from the WTRU including an indication to establish the user plane based on the second response message.
22. The network node of claim 16, wherein the processor is configured to:
determine whether a location of the WTRU has been changed; on a condition that the location of the WTRU has been changed, determine whether the changed location of the WTRU is in the allowed area or the non-allowed area; and send a WTRU location update message to a radio access node (RAN) indicating that the changed location of the WTRU is in the allowed area or the non-allowed area.
23. The network node of claim 16, wherein the first request message comprises a service request message, and wherein the second request message comprises a registration message.
24. The network node of claim 16, wherein the processor is configured to:
periodically determine whether a location of the WTRU has been changed.
25. The network node of claim 16, wherein the network node comprises an access and mobility management function (AMF).
26. A method for a network node comprising:
receiving a first request message from a wireless transmit/receive unit (WTRU), the first request message comprising an indication to establish a user plane; determining whether the WTRU is located in an allowed area or a non-allowed area; and based on a determination that the WTRU is in the non-allowed area, sending a first response message to the first request message, the first response message indicating that the WTRU is located in a non-allowed area and that the WTRU is not allowed to send a request to establish the user plane in the non-allowed area.
27. The method of claim 26, comprising:
receiving a second request message from the WTRU without the indication to establish the user plane.
28. The method of claim 26, comprising:
updating a tracking area list (TAU) associated with a location of the WTRU based on the determination that the WTRU is in the allowed area or the non-allowed area.
29. The method of claim 26, comprising:
determining whether a location of the WTRU has been changed; based on a determination that the location of the WTRU has been changed, determining whether the changed location of the WTRU is in the allowed area or the non-allowed area; on a condition that the changed location of the WTRU is in the allowed area, sending a second response message to the WTRU indicating that the WTRU is located in the allowed area and that the WTRU is allowed to send the request to establish the user plane; and on a condition that the changed location of the WTRU is in the non-allowed area, sending the second response message to the WTRU indicating that the WTRU is located in the non-allowed area and that the WTRU is not allowed to send the request to establish the user plane in the non-allowed area.
30. The method of claim 29, comprising:
receiving a second request message from the WTRU without the indication to establish the user plane based on the second response message.
31. The method of claim 29, comprising:
receiving a second request message from the WTRU including an indication to establish the user plane based on the second response message.
32. The method of claim 26, comprising:
determining whether a location of the WTRU has been changed; on a condition that the location of the WTRU has been changed, determining whether the changed location of the WTRU is in the allowed area or the non-allowed area; and sending a WTRU location update message to a radio access node (RAN) indicating that the changed location of the WTRU is in the allowed area or the non-al lowed area.
33. The method of claim 26, wherein the first request message comprises a service request message, and wherein the second request message comprises a registration message.
34. The method of claim 26, comprising:
periodically determining whether a location of the WTRU has been changed.
35. The method of claim 26, wherein the network node comprises an access and mobility management function (AMF).
