Abstract
A network access control method and an apparatus are disclosed. The method includes controlling, by a first network device if determining that a terminal device already establishes a second data connection to a second network, the terminal device to stop establishment of a first data connection to a first network, or controlling the terminal device to end the second data connection, to smoothly establish a first data connection. In this way, it can be ensured that a data connection exists between the terminal device and one network, and it can be ensured that the terminal device can normally transmit data.
Claims20
A network access control method, comprising:
- determining, by a first network device after a terminal device requests to establish a first data connection to a first network, that a second data connection exists between the terminal device and a second network;
- and
- performing, by the first network device, one of the following operations:
- instructing, by the first network device, the terminal device to stop the establishment of the first data connection;
- instructing, by the first network device, the terminal device to end the second data connection, or after the first network device ends the second data connection, continuing, by the first network device, to perform a procedure of establishing the first data connection;
- or
- instructing, by the first network device, a second network device to end the second data connection, and instructing a third network device to establish the first data connection.
A first network device comprising:
- at least one processor and a memory storing computer instructions, wherein the computer instructions are executed by the at least one processor to cause the first network device to:
- determine that a second data connection exists between a terminal device and a second network after the terminal device requests to establish a first data connection to a first network;
- and
- perform one of the following operations:
- instruct the terminal device to stop the establishment of the first data connection;
- instruct the terminal device to end the second data connection, or after the second data connection is broken, continuing to perform a procedure of establishing the first data connection;
- or
- instruct a second network device to end the second data connection, and instruct a third network device to establish the first data connection.
A terminal device comprising:
- at least one processor and a memory storing computer instructions, wherein the computer instructions are executed by the at least one processor to cause the terminal device to:
- send a request to establish a first data connection to a first network;
- receive an access stop message sent by a first network device, wherein the access stop message is used to instruct the terminal device to stop the establishment of the first data connection;
- and
- stop a procedure of establishing the first data connection.
