Abstract

Embodiments of the present invention relate to the wireless communications field, and provide a terminal switching method, an access device, a terminal, and a system. The method includes: establishing, by a first access device, an NFC connection to a second access device; receiving, by the first access device, an authentication parameter that is sent by the second access device by using the NFC connection; and performing access authentication on a to-be-switched terminal according to the authentication parameter, and establishing a second connection to the to-be-switched terminal after the authentication succeeds. An NFC connection is established to a second access device, an authentication parameter that is sent by the second access device by using the NFC connection is received, access authentication is performed on a to-be-switched terminal according to the authentication parameter, and a connection is established to the to-be-switched terminal after the authentication succeeds.

Claims

1. A terminal switching method, wherein the method comprises:

when a distance between a first access device and a second access device falls within a range of a near field communication (NFC) connection, establishing, by the first access device, an NFC connection to the second access device;

receiving, by the first access device, an authentication parameter of a to-be-switched terminal that is sent by the second access device by using the NFC connection, wherein the to-be-switched terminal is a terminal that has established a first connection to the second access device;

receiving, by the first access device, an authentication request sent by the to-be-switched terminal; and

performing, by the first access device, access authentication on the to-be-switched terminal according to the authentication parameter, and establishing a second connection to the to-be-switched terminal after the authentication succeeds.

2. The method according to claim 1, wherein the method further comprises:

receiving a channel parameter that is sent by the second access device by using the NFC connection, wherein the channel parameter is an access channel parameter of the to-be-switched terminal; and

the establishing a second connection to the to-be-switched terminal after the authentication succeeds comprises;

establishing the second connection to the to-be-switched terminal according to the channel parameter.

3. The method according to claim 1, wherein the method further comprises:

sending a connection success response to the to-be-switched terminal, wherein the connection success response is used to instruct the to-be-switched terminal to cancel the first connection to the second access device.

4. A terminal switching method, wherein the method comprises:

when a distance between a first access device and a second access device falls within a range of a near field communication NFC connection, establishing, by the second access device, an NFC connection to the first access device; and

sending, by the second access device, an authentication parameter of a to-be-switched terminal to the first access device by using the NFC connection, wherein the to-be-switched terminal is a terminal that has established a first connection to the second access device, and the authentication parameter is used to instruct the first access device to perform access authentication on the to-be-switched terminal according to the authentication parameter and establish a second connection to the to-be-switched terminal after the authentication succeeds.

5. The method according to claim 4, wherein the method further comprises:

sending a channel parameter to the first access device by using the NFC connection, wherein the channel parameter is an access channel parameter of the to-be-switched terminal.

6. The method according to claim 4, wherein the method further comprises:

after the first access device has established the second connection to the to-be-switched terminal, canceling the first connection to the to-be-switched terminal.

7. A terminal switching method, wherein the method comprises:

sending, by a to-be-switched terminal, an authentication request to a first access device, wherein the to-be-switched terminal is a terminal that has established a first connection to a second access device, and the authentication request is used to instruct the first access device to perform access authentication on the to-be-switched terminal according to an authentication parameter, wherein the authentication parameter is a parameter that is sent to the first access device by the second access device by using a near field communication NFC connection; and

after the authentication by the first access device succeeds, establishing, by the to-be-switched terminal, a second connection to the first access device.

8. The method according to claim 7, wherein the method further comprises:

receiving a connection success response sent by the first access device.

9. An access device, wherein the access device comprises:

a first connection establishment module, configured to;

when a distance to a second access device falls within a range of a near field communication NFC connection, establish an NFC connection to the second access device;

an authentication parameter receiving module, configured to receive an authentication parameter of a to-be-switched terminal that is sent by the second access device by using the NFC connection, wherein the to-be-switched terminal is a terminal that has established a first connection to the second access device;

a request receiving module, configured to receive an authentication request sent by the to-be-switched terminal;

an authentication module, configured to perform access authentication on the to-be-switched terminal according to the authentication parameter; and

a second connection establishment module, configured to;

after the authentication by the authentication module succeeds, establish a second connection to the to-be-switched terminal.

10. The access device according to claim 9, wherein the access device further comprises:

a channel parameter receiving module, configured to;

before the second connection establishment module establishes the second connection to the to-be-switched terminal, receive a channel parameter that is sent by the second access device by using the NFC connection, wherein the channel parameter is an access channel parameter of the to-be-switched terminal; and

the second connection establishment module is configured to establish the second connection to the to-be-switched terminal according to the channel parameter.

11. The access device according to claim 9, wherein the first access device further comprises:

a response sending module, configured to send a connection success response to the to-be-switched terminal, wherein the connection success response is used to instruct the to-be-switched terminal to cancel the first connection to the second access device.

12. A terminal, wherein the terminal comprises:

a request sending module, configured to send an authentication request to a first access device, wherein the authentication request is used to instruct the first access device to perform access authentication on the to-be-switched terminal according to an authentication parameter, wherein the authentication parameter is a parameter that is sent to the first access device by the second access device by using a near field communication NFC connection; and

a fourth connection establishment module, configured to;
