Manual network selection at a user equipment
A user equipment (UE) displays a list of available networks for manual network selection. The UE detects multiple networks during a public land mobile network (PLMN) scan, wherein the multiple networks include one or more PLMNs and one or more stand-alone non-public networks (SNPNs), generates a manual network selection list that includes at least i) the one or more PLMNs or ii) the one or more SNPNs, determines a sequence in which entries of the manual network selection list are to be displayed at the UE, displays a graphical user interface (GUI) that includes a representation of the manual network selection list and registers with one of the multiple networks in response to user input.
1. A method, comprising:
at a user equipment (UE):
detecting multiple networks during a public land mobile network (PLMN) scan, wherein the multiple networks include a plurality of PLMNs and a plurality of stand-alone non-public networks (SNPNs);
generating a manual network selection list that includes at least i) the plurality of PLMNs or ii) the plurality of SNPNs;
determining a sequence in which entries of the manual network selection list are to be displayed at the UE, wherein networks are ordered within the sequence based on, at least, being previously successfully registered upon by the UE and supported Radio Access Technologies (RATs);
displaying a graphical user interface (GUI) that includes a representation of the manual network selection list; and
registering with one of the multiple networks in response to user input.
2. The method of claim 1 , wherein the plurality of PLMNs are ordered within the sequence based on not being a home PLMN (HPLMN), an equivalent HPLMN (EHPLMN), a user controlled PLMN (UPLMN) or an operator controlled PLMN (OPLMN) for the UE.
3. The method of claim 2 , wherein the UPLMN is a PLMN included in a user controlled PLMN selector with access technology list stored on a subscriber identity module (SIM) and the OPLMN is a PLMN included in an operator controlled PLMN selector with access technology list stored on the SIM.
4. The method of claim 2 , wherein a further one of the plurality of PLMNs is ordered within the sequence based on being a forbidden PLMN (FPLMN) or an equivalent PLMN (EPLMN) to any of the OPLMN or the UPLMN.
5. The method of claim 2 , further comprising:
receiving steering of roaming (SoR) information from the HPLMN, wherein the SOR information includes one or more OPLMNs.
6. The method of claim 5 , wherein the SoR information is received prior to the PLMN scan and wherein a first PLMN of the plurality of PLMNs is ordered within the sequence relative to a second PLMN of the plurality of PLMNs based on the first PLMN being indicated in the SoR information.
7. The method of claim 5 , further comprising:
updating the sequence of the plurality of PLMNs based on the SoR information, wherein the SoR information is received while the GUI is displayed.
8. The method of claim 5 , further comprising:
generating a further manual network selection list in response to receiving the SoR information, wherein the SoR information is received after the registering.
9. The method of claim 8 , further comprising:
determining a further sequence in which the plurality of PLMNs are to be displayed at the UE within a representation of the further manual network selection list, wherein a first PLMN of the plurality of PLMNs is ordered within the further sequence relative to a second PLMN of the plurality of PLMNs based on the first PLMN being indicated in the SoR information.
10. The method of claim 1 , further comprising:
identifying that a first PLMN of the plurality of PLMNs supports non-standalone (NSA) mode, wherein the UE is operating in standalone (SA) mode when generating the manual network selection list and wherein the manual network selection list does not include the first PLMN based on the UE operating in SA mode.
11. The method of claim 10 , wherein identifying that the first PLMN supports NSA mode is based on at least one of (i) information transmitted over a physical broadcast channel (PBCH) or (ii) not receiving a system information block 1 (SIB 1 ) from a cell of the first PLMN.
12. The method of claim 1 , wherein the UE excludes the plurality of SNPNs from the manual network selection list based on operating in a PLMN only mode.
13. The method of claim 12 , wherein the UE is not camped on a network when generating the manual network selection list and wherein the order of the sequence is based a signal parameter.
14. The method of claim 1 , wherein the UE excludes the plurality of PLMNs from the manual network selection list based on operating in an SNPN only mode.
15. The method of claim 1 , wherein the UE is camped on a first SNPN of the plurality of SNPNs when generating the manual network selection list and wherein the first SNPN is included in the sequence before the plurality of PLMNs based on the UE being camped on the first SNPN.
16. The method of claim 1 , wherein the UE is camped on a first PLMN of the plurality of PLMNs when generating the manual network selection list and wherein one of the PLMNs is included in the sequence before the plurality of SNPNs based on the UE being camped on the first PLMN.
17. A user equipment (UE), comprising:
a transceiver configured to perform a public land mobile network (PLMN) scan; and
a processor configured to:
detect multiple networks during the PLMN scan, wherein the multiple networks include a plurality of PLMNs and a plurality of stand-alone non-public networks (SNPNs),
generate a manual network selection list that includes at least i) the plurality of PLMNs or ii) the plurality of SNPNs,
determine a sequence in which entries of the manual network selection list are to be displayed at the UE, wherein networks are ordered within the sequence based on, at least, being previously successfully registered upon by the UE, and supported Radio Access Technologies (RATs),
display a graphical user interface (GUI) that includes a representation of the manual network selection list, and
register with one of the multiple networks in response to user input.
18. The UE of claim 17 , wherein the plurality of PLMNs are ordered within the sequence based not being a home PLMN (HPLMN), an equivalent HPLMN (EHPLMN), a user controlled PLMN (UPLMN) or an operator controlled PLMN (OPLMN) for the UE.
19. The UE of claim 17 , wherein the processor is further configured to:
receive steering of roaming (SoR) information from the HPLMN, wherein the SOR information includes one or more OPLMNs; and
update the sequence of the one or more PLMNs based on the SoR information.
20. The UE of claim 17 , wherein the processor is further configured to:
Identify that a first PLMN of the plurality of PLMNs supports non-standalone (NSA) mode, wherein the UE is operating in standalone (SA) mode when generating the manual network selection list and wherein the manual network selection list does not include the first PLMN based on the UE operating in SA mode,
wherein identifying that the first PLMN supports NSA mode is based on at least one of (i) information transmitted over a physical broadcast channel (PBCH) or (ii) not receiving a system information block 1 (SIB 1 ) from a cell of the first PLMN.
