US 11,540,187 B2 · Methods for enforcing limited mobility in mobile network

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.

Dependent claims

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 that the WTRU is located in a non-allowed area;
and
based on the determination that the WTRU is in the non-allowed area, send a first response message to the first request message, the first response message comprising an indication that the WTRU is located in the non-allowed area and an indication that the network node is preventing the user plane from being established in the non-allowed area;
and
receive a second request message without the indication to establish the user plane, wherein the second request message is sent by the WTRU in response to the indication that the WTRU is located in the non-allowed area.

A method performed by a network node, the method 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 that the WTRU is located in a non-allowed area;
and
based on the determination that the WTRU is in the non-allowed area, sending a first response message to the first request message, the first response message comprising an indication that the WTRU is located in the non-allowed area and an indication that the network node is preventing the user plane from being established in the non-allowed area;
and
receiving a second request message without the indication to establish the user plane, wherein the second request message is sent by the WTRU in response to the indication that the WTRU is located in the non-allowed area.
