Detailed Description
The technical solution of the present disclosure is further described in detail by the accompanying drawings and examples.
In the case that the base station is an NSA shared anchor base station, a flowchart of some embodiments of the terminal camping method of the present disclosure is shown in fig. 1.
In step 101, the base station transmits 5G PLMN information to the terminal. The operator can apply for a new PLMN for the 5G network, and broadcast two PLMNs in the shared network of 4G and 5G, where the 4G base station uses the original 4G PLMN, and the NSA shared anchor base station uses the new 5G PLMN. The 4G PLMN is different from the 5G PLMN.

In step 102, the terminal matches with the 5G PLMN information of the base station based on the pre-stored PLMN information. If the matching is successful, triggering the base station to execute step 103; if the matching is not successful, the base station is triggered to execute step 104.
In step 103, the terminal is a terminal supporting 5G functions and can be resident in the current 5G network.
In step 104, the terminal does not support the 5G function and cannot reside in the current 5G network.

In the case that the base station is a 4G base station, a flowchart of some embodiments of the terminal camping method of the present disclosure is shown in fig. 2.
In step 201, the 4G base station transmits 4G PLMN information to the terminal.
In step 202, the terminal matches PLMN information of the base station based on pre-stored PLMN information. In case the matching is successful, step 203 is performed.
In step 203, the terminal reports the acquired terminal capability information to the base station. In some embodiments, the terminal may carry the terminal capability information in the service attach information, and the base station acquires the terminal capability information.
In step 204, the base station determines that the terminal supports the 5G function according to the obtained terminal capability information. In case it is determined that the terminal supports the 5G function, step 205 is performed; in case it is determined that the terminal does not support 5G, step 206 is performed.
In step 205, a proprietary frequency priority is issued to the terminal. In the dedicated frequency priority, the NSA shared anchor base station frequency priority is higher than the 4G base station frequency. The terminal will reselect the network for access based on the dedicated frequency priority.
