Step 102: and judging whether the terminal is a private network user or not based on the mobile information.
Preferably, the determining whether the terminal is a private network user based on the mobile information may include:
and when the terminal is accessed to the third area private network cell and the terminal resides in the first area indoor sub-cell and the second area private network cell, judging that the terminal is a private network user.
Step 103: and if so, allocating a private network user identifier and private network frequency point information to the terminal.
Specifically, when the terminal is in a connected state, a private network user identifier and private network frequency point information are allocated to the terminal.
Step 104: and issuing the private network user identification and the private network frequency point information to a terminal so that the terminal resides in the private network based on the private network user identification and the private network frequency point information.
Preferably, the issuing the private network user identifier and the private network frequency point information to a terminal may include:
when the terminal is in a connection state, the private network user identification and the private network frequency point information are issued to the terminal through an RRC reconfiguration message; and carrying the private network user identification and the private network frequency point information in a reserved field of the RRC reconfiguration message.

and in the coverage range of a private network, when the terminal is separated from the private network and then selects the network again, the terminal preferentially selects a private network frequency point cell for registration so as to ensure that the terminal returns to the private network in time.
Therefore, when the terminal is positioned in the coverage area of the private network, the private network can be accessed quickly even if the terminal is disconnected at a certain moment.
Preferably, after the private network user identifier and the private network frequency point information are issued to a terminal, the method further includes:
detecting whether the terminal leaves the coverage range of the private network or not;
if so, notifying the terminal as a non-private network user through the RRC reconfiguration message, so that the terminal updates user information into the non-private network user after receiving the RRC reconfiguration message, and performs network selection according to a common user.

counting user information of a terminal accessed to a waiting hall sub-cell in a high-speed rail railway station, and transmitting the user information to a high-speed rail platform private network cell through an X2 interface according to a certain time interval;
when the terminal enters a high-speed rail platform private network cell and the terminal resides in a waiting hall sub-cell, the platform private network cell forwards the user information to the next adjacent high-speed rail private network cell through an X2 interface at certain time intervals;
when the terminal is accessed to a high-speed rail private network cell adjacent to the platform private network cell and the user resides in the waiting hall sub-cell and the platform private network cell, the terminal can be judged to be a high-speed rail private network user.
Fig. 3 is a schematic diagram of determining whether a user is an LTE private network user in a high-speed rail scene, as shown in fig. 3, user information of a terminal accessed to a waiting hall sub-cell of a station is counted, the user information is transmitted to a high-speed rail platform private network cell through an X2 interface, and when the terminal enters the high-speed rail platform private network cell and the terminal resides in the waiting hall sub-cell, the high-speed rail platform private network cell transmits the user information to a next adjacent high-speed rail private network cell through an X2 interface; when the terminal is accessed to the adjacent high-speed rail private network cell and the user resides in the waiting hall sub-cell and the platform private network cell, the user can be judged to be the high-speed rail user.
Fig. 4 is a schematic diagram of a switching process between stations based on an X2 interface in a high-speed rail scene, where as shown in the drawing, the switching process mainly includes:
step 401: a source base station (source eNodeB) sends a handover request (handover request) to a target base station (target eNodeB);
step 402: the target base station sends a handover request acknowledgement (handover requseacknowledgment) message to the source base station;
the above steps 401 and 402 belong to the handover preparation success flow.
Step 403: a source base station transmits an RRC connection Reconfiguration (RRCConnection Reconfiguration) message to a terminal (UE);
step 404: a source base station sends a sequence state transmission (SN status transfer) message to a target base station;
specifically, the sequence state transmission message may be sent in a Data Forwarding (Data Forwarding) manner, that is: the output value content of one cell is copied to the input value of another cell in one clock cycle.
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 transmits a path switch request message to a Mobility Management Entity (MME) to confirm that the UE has changed cells.
Step 407: MME sends a path switching request acknowledgement (path switching request acknowledgement) message to a target base station;
step 408: and the target base station sends a UE context release message to the source base station.
After the determination in step 202, the following operation is continued for the terminal determined as the high-speed user.
Step 203: and issuing the high-speed rail private network user identification and the preferred frequency point to the high-speed rail user terminal.
The high-speed user terminal is the terminal determined as the high-speed user in step 202.
Specifically, the issuing of the high-speed rail private network user identifier and the preferred frequency point to the high-speed rail user terminal may include the following parts:
(a) if the terminal is in a connected state, carrying private network user identification and preferred frequency point information in a reserved field through RRC reconfiguration information, and issuing the information to the terminal;
(b) after the terminal receives the private network user identification information and the preferred frequency point information, whether the current terminal is the private network user identification or not and the preferred frequency point information when the network is disconnected are updated.
(c) And c, transmitting the private network user information to the next adjacent private network cell for the high-speed rail through an X2 interface, and continuously repeating the process of the step b until the terminal leaves the private network cell for the high-speed rail.
Step 204: and the high-speed rail user terminal resides in 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 in the private network coverage area, if the high-speed rail user terminal is off-line, step 206 is executed.
Step 206: and when the high-speed rail user terminal selects the network again, the private network frequency point cell is preferentially selected for registration.
That is, when the terminal is disconnected from the network and selects the network again, if the terminal is a high-speed rail private network user, the private network frequency point cell is preferentially selected for registration, so as to ensure that the terminal returns to the high-speed rail private network in time.
Step 207: and when the high-speed rail user terminal is detected to leave the coverage range of the high-speed rail private network, issuing a user identifier for canceling the high-speed rail private network to the high-speed rail user terminal.
For example, when the user arrives at a railway station and the terminal exits a private network cell through the railway station, the terminal is notified of a non-private network user through an RRC reconfiguration message, so that the terminal updates user information to the non-private network user after receiving the RRC reconfiguration message, and performs network selection according to a common user.
According to the method for the LTE private network user residence in the high-speed rail scene, firstly, according to the movement track of a terminal, whether the terminal is a high-speed rail private network terminal is judged by combining a railway station waiting hall, a high-speed rail platform private network cell and an adjacent first high-speed rail private network cell; secondly, if the terminal is a high-speed rail private network user and is in a connected state, carrying high-speed rail private network user information and private network frequency point information through RRC reconfiguration information, and storing after receiving the information by the terminal; under the condition that the high-speed train moves rapidly, if the terminal is separated from the private network, when the user selects the network again, the high-speed train private network frequency point is preferentially selected, and the terminal is ensured to be registered and returned to the private network in time; and finally, when the terminal leaves a special network cell of the outbound railway station, informing the user to cancel the high-speed rail user information through an RRC reconfiguration message, and subsequently performing network registration or reselecting the LTE public network according to the common user.
