5.2.2.2 主要子状态选择
5.2.2.2.1 Selection of the substate after power on
5.2.2.2.1 开机后子状态的选择
For a UE configured for eCall only mode as specified in 3GPP TS 31.102 [22], timers T3444 and T3445 are considered to have expired at power on. When the UE is switched on, the substate shall be PLMN-SEARCH if the USIM is available and valid or there are valid entries in the "list of subscriber data". See 3GPP TS 23.122 [5] for further details.
对于配置为3GPP TS 31.102[22]中规定的仅eCall模式的UE，定时器T3444和T3445被视为在开机时已过期。当UE开机时，如果USIM可用且有效或“用户数据列表”中有有效条目，则子状态应为PLMN-搜索。有关更多详细信息，请参见3GPP TS 23.122[5]。
The substate chosen after PLMN-SEARCH, following power on is:
在PLMN-搜索之后选择的子状态为：
a) if no cell can be selected, the substate shall be NO-CELL-AVAILABLE;
