測驗步驟

以38523 -1 -g30協議為參考，先看一下NG-RAN單模的PLMN選擇用例，章節號：6.1.1.1

測驗目的

在RPLMN\HPLMN\UPLMN\OPLMN都有效，而且RPLMN有限場景中，終端回到覆寫區，應該優先選擇RPLMN，并發起注冊，

with { UE in Automatic network selection mode and RPLMN, HPLMN, UPLMN and OPLMN NR cells available

and UE is fitted with a USIM indicating RPLMN should be selected }

ensure that {

when { UE is switched on or return to coverage }

then { UE selects a cell of the RPLMN and UE attempts Registration on the selected cell }

}

當駐留在VPLMN時，高優先級的PLMN可用時，應該周期性去搜索高優先級小區，

with { UE camped on an NG-RAN VPLMN cell and cells of a higher priority NG-RAN PLMN available }

ensure that {

when { higher priority PLMN search timer T expires }

then { UE selects and camps on a cell of the highest priority PLMN and UE attempts Registration with mobility on the selected cell }

}

自動選網時，按照優先級順序依次選網

with { UE in Automatic network selection mode and HPLMN, UPLMN and OPLMN NG-RAN cells available and

UE is fitted with a USIM with Access Technology data files for each PLMN and there are no equivalent HPLMNs defined}

ensure that {

when { UE is switched on or return to coverage }

then { UE selects a cell of the highest priority PLMN and UE attempts Registration with mobility on the selected cell }

}

在VPLMN時，如果HPLMN可用，需要T周期內駐留到HPLMN

with { UE camped on an NR VPLMN cell and cells of a NG-RAN HPLMN available }

ensure that {

when { higher priority PLMN search timer T expires }

then { UE selects and camps on a cell of HPLMN and UE attempts Registration on the selected cell }

協議依據

比如，

下面這個就是告訴我們選網的優先級順序，

[TS 23.122, clause 4.4.3.1.1]

The MS selects and attempts registration on other PLMN/access technology combinations, if available and allowable, in

the following order:

i) either the HPLMN (if the EHPLMN list is not present or is empty) or the highest priority EHPLMN that is

available (if the EHPLMN list is present) ;

ii) each PLMN/access technology combination in the "User Controlled PLMN Selector with Access Technology" data file in the SIM (in priority order);

iii) each PLMN/access technology combination in the "Operator Controlled PLMN Selector with Access Technology"data file in the SIM (in priority order);

iv) other PLMN/access technology combinations with received high quality signal in random order;

v) other PLMN/access technology combinations in order of decreasing signal quality

測驗條件

System Simulator:指定當前系統配置

四個異頻小區，各小區的PLMN配置參考如下表，所有小區都是高質量小區，是suitable小區；
