Methods and apparatus for steering a wireless/transmit receive unit between multiple wireless networks
A method implemented in a Wireless Transmit/Receive Unit, WTRU, for selecting a local network for the WTRU to join includes storing steering of roaming, SoR, information for a plurality of local service hosting networks, wherein the SoR information includes an indication of a priority order in a list of network identifiers, switching to an access mode for network searching, searching for a local service hosting network to join from among the plurality of local service hosting networks, and selecting a local service hosting network to join based on the indication of the priority order in the list of network identifiers. The method may further include updating the SoR information during any one or more of a periodic procedure or a mobility registration procedure.

select a network providing localized services based on the prioritized list of one or more networks providing localized services, on a condition that a current time is within the time period associated with the selected network providing localized services;
search for the selected network providing localized services; and
on a condition that the selected network providing localized services is found, register with the selected network providing localized services.

5. The WTRU of claim 1 , wherein the prioritized list of one or more networks providing localized services includes a plurality of networks providing localized services.
6. The WTRU of claim 1 , wherein the WTRU is further configured to update the SoR information during any one or more of a periodic procedure or a mobility registration procedure.
7. The WTRU of claim 1 , wherein each network in the prioritized list of one or more networks providing localized services is associated with a geographic area corresponding to an area within which the network is available.
8. The WTRU of claim 1 , wherein the WTRU is further configured to select a network providing localized services with which to connect using a network selector function of the WTRU circuitry.
9. The WTRU of claim 1 , wherein the selected network providing localized services is associated with a geographic area that comprises a current location of the WTRU.

selecting a network providing localized services based on the prioritized list of one or more networks providing localized services, on a condition that a current time is within the time period associated with the selected network providing localized services;
searching for the selected network providing localized services; and
on a condition that the selected network providing localized services is found, registering with the selected network providing localized services.
11. The method of claim 10 , further comprising connecting to the selected network providing localized services .
12. The method of claim 10 , wherein searching for a network providing localized services with which to connect is performed after switching from a Public Land Mobile Network operating mode to a Stand Alone Non-Public Network (SNPN) access mode.
13. The method of claim 10 , wherein the SoR information is provided by a Public Land Mobile Network.
14. The method of claim 10 , wherein the prioritized list of one or more networks providing localized services includes a plurality of networks providing localized services.
15. The method of claim 10 , wherein the method further comprises updating the SoR information during any one or more of a periodic procedure or a mobility registration procedure.
16. The method of claim 10 , wherein each network in the prioritized list of one or more networks providing localized services is associated with a geographic area corresponding to an area within which the network is available.
17. The method of claim 10 , wherein selecting a network providing localized services with which to connect comprises using a network selector function of the WTRU.
