PLMN selection sequence during power on or cell reselection specified in 3GPP 23122

In 3GPP 23122, the following instructions are given for PLMN selection during power on or cell reselection. When power on or cell reselection occurs, the mobile terminal first attempts to select RPLMN (registered PLMN, successfully logged in to PLMN last time). If RPLMN selection fails, select in the following order: The article originates from the fallen fish- https://www.duoluodeyu.com/2301.html

1. HPLMN (if the EHPLMN list does not exist or is empty) or the highest priority EHPLMN (if the EHPLMN list exists); The article originates from the fallen fish- https://www.duoluodeyu.com/2301.html

2. Select from the USIM/SIM card data according to the UPLMN priority order; (User Controlled PLMN Selector with Access Technology)； The article originates from the fallen fish- https://www.duoluodeyu.com/2301.html

3. Select from USIM/SIM card data according to OPLMN priority order; (Operator Controlled PLMN Selector with Access Technology)； The article originates from the fallen fish- https://www.duoluodeyu.com/2301.html

4. Randomly select PLMN access technology combination formed by RSCP value greater than - 84dBm (sufficient strength signal quality); The article originates from the fallen fish- https://www.duoluodeyu.com/2301.html

5. When the signal strength is insufficient, select all other PLMNs according to the descending order of the received signal strength. The article originates from the fallen fish- https://www.duoluodeyu.com/2301.html
