Step 401: a source base station (source eNodeB) sends a handover request (handover requset) to a target base station (target eNodeB);

Step 402: the target base station sends a handover request acknowledgement (handover requsetacknowledge) message to the source base station;

The above steps 401 and 402 belong to the successful handover preparation process.

Step 403: The source base station sends an RRC Connection Reconfiguration (RRCConnection Reconfiguration) message to a terminal (UE, User Equipment);

Step 404: the source base station sends a sequence status transfer (SN stautus transfer) message to the target base station;

Specifically, a data forwarding (Data Forwarding) manner can be used to send the sequence state transmission message, that is, within one clock cycle, the content of the output value of one unit is copied to the input value of another unit.

Step 405: the UE sends an RRC connection reconfiguration complete (RRC ConnectionReconfiguration Complete) message to the target base station;

Step 406: The target base station sends a path switch request (path switch request) message to a mobility management entity (MME, Mobility Management Entity) to confirm that the UE has changed cells.

Step 407: the MME sends a path switch request acknowledgement (path switch request acknowledge) message to the target base station;

Step 408: The target base station sends a UE context release message to the source base station.

(a) If the terminal is in the connected state, carry the private network user identifier and preferred frequency information in the reserved field through the RRC reconfiguration message, and deliver it to the terminal;

(b) After the terminal receives the private network user identification information and the preferred frequency information, it updates whether the current terminal is a private network user identification and the preferred frequency information when off-network.

(c) Transfer the private network user information to the next adjacent high-speed rail private network cell through the X2 interface, and repeat the process of step b above until the terminal leaves the high-speed rail private network cell.

Step 204: The high-speed rail user terminal resides on the high-speed rail private network based on the high-speed rail private network user identifier and the preferred frequency point.

Step 205: When the high-speed rail user terminal is within the coverage of the private network, if the high-speed rail user terminal is disconnected from the network, step 206 is performed.

Step 206: When the high-speed rail user terminal selects the network again, it preferentially selects the private network frequency cell for registration.

That is to say, when the terminal is disconnected from the network and the network is selected again, if the terminal is a user of the high-speed rail private network, the private network frequency cell is preferentially selected for registration to ensure that the terminal returns to the high-speed rail private network in time.

Step 207: It is detected that the high-speed rail user terminal leaves the coverage of the high-speed rail private network network, and the cancellation of the high-speed rail private network user identification is issued to the high-speed rail user terminal.

For example, after the user arrives at the railway station, when the terminal exits the private network cell through the railway station, the terminal is notified through the RRC reconfiguration message that the terminal is a non-private network user, so that the terminal can receive the RRC reconfiguration message after receiving the RRC reconfiguration message.
