One of the core concepts of the present invention is that, a first base station detects that a base station handover is successful at a user terminal bearer termination, and sends a bearer update message carrying a Radio Access Technologies Type (RAT-Type) of the user terminal to a core network, so that the core network can update the RAT-Type of the user terminal on a network side, so that the core network can perform charging according to the RAT-Type.

Referring to FIG. 1, a block diagram of an embodiment of a data processing system of the present invention is shown, the system comprising: the access control method comprises a core network 10, a first base station 11, a second base station 12 and a user terminal 13, wherein the mobile communication technology order of the second base station 12 is higher than that of the first base station 11, the access between the first base station 11 and the user terminal 13 comprises a user plane data access and a control plane data access, and the access between the second base station 12 and the user terminal 13 comprises a user plane data access; the core network 10 is a core network of the first base station 11, that is, the core network 10 and the first base station 11 may establish a user plane data path and a control plane data path, and the second base station 12 may establish a user plane data path with the core network 10 or may not establish a user plane data path with the core network 10.

The first base station 11 is configured to detect that a base station handover of a user terminal 13 bearer termination is successful, and generate a bearer update message, where the bearer update message includes a target radio access technology Type RAT-Type of the user terminal, the RAT-Type corresponds to a mobile communication technology order of a base station of the user terminal 13 bearer termination, and the base station of the user terminal bearer termination includes the first base station 11 and the second base station 12; and sending the bearer update message to the core network 10;

the core network 10 is configured to update the RAT-Type of the network-side ue, the base station IP and the tunnel information corresponding to the bearer of the ue, and initiate an update procedure of QoS (Quality of Service) corresponding to the bearer of the ue according to the bearer update message.

In this embodiment of the present invention, the first base station 11 and the second base station 12 may establish a user plane data path and a control plane data path, and when the first base station 11 detects that there is a second base station 12 that satisfies a first setting condition around, the first base station can instruct part of the user terminals 13 to switch the base station whose bearer is terminated, that is, instruct part of the user terminals 13 to switch the bearer from the first base station 11 to the second base station 12; alternatively, when it is determined that the second base station 12 does not satisfy the second setting condition, the user terminal 13 whose bearer is terminated on the second base station 12 may be instructed to switch its bearer to the first base station 11. The first base station 11 may perform control plane data (signaling) interaction with the second base station 12 to determine whether to instruct the user terminal 13 to switch the base station with its bearer termination, where the first setting condition and the second setting condition may be set as required. The first base station 11 instructs the user terminal 13 to switch the base station with the bearer termination, and the user terminal 13 can switch the base station with the bearer termination according to the instruction; after detecting that the base station handover is successful, the first base station 11 may generate a corresponding bearer update message, and then send the bearer update message to the core network 10, so as to inform the core network 10 that the base station corresponding to the user terminal bearer is updated.

On the other hand, the network performance corresponding to different mobile communication technologies is different, for example, the maximum accessible uplink of the user terminal of the 4G base station is 50Mbps, and the maximum accessible downlink is 100Mbps, while the maximum accessible uplink of the user terminal of the 5G base station is 10Gbps, and the maximum accessible downlink is 20 Gbps; therefore, the QoS corresponding to different RAT-types is different, and the core network 10 may initiate an update procedure of the QoS corresponding to the bearer of the ue, so as to update the configuration information corresponding to the bearer of the ue. Referring to fig. 2, a flowchart of carrying an update according to an embodiment of the present invention is shown.

In addition, the core network can update the base station IP and the tunnel information corresponding to the bearer of the user terminal according to the bearer update message, and initiate an update process of the quality of service (QoS) corresponding to the bearer of the user terminal, thereby realizing the update of the corresponding configuration information of the bearer of the user terminal.
