With the popularization and development of wireless communication network technology, the switching of frequency bands in wireless roaming communication is a major focus in the field of communication at present. At present, when a wireless terminal is in communication connection with an AP (Access Point), a situation that a wireless terminal user crosses from one AP service area to another AP service area often occurs while moving, so that roaming handover is required, the connected AP device needs to be disconnected first in the roaming handover, and then the AP device needs to be reconnected with a new AP device, but data delay or data interruption and other situations affecting user experience may occur in the roaming handover process.
Based on this, the invention discloses a roaming switching method, an electronic device and a computer readable storage medium, which relate to the field of communication and are applied to a slave device in communication connection with a first master device.

Referring to fig. 1, roaming refers to communication connection between the slave device 100 and the first master device 200 in an initial state, and the slave device 100 is in communication connection with the management center 400 through the first master device 200. After the roaming handover is performed, the communication connection between the slave device 100 and the first master device 200 is disconnected, and a new communication connection is established between the slave device 100 and the second master device 300, so that the communication connection with the management center 400 can be established through the second master device 300 after the new communication connection is established between the slave device 100 and the second master device 300.
Referring to fig. 2, a flowchart of a roaming handover method in an embodiment of the present invention is shown, which is applied to the slave device 100 communicatively connected to the first master device 200. The method specifically comprises the following steps:
s100, scanning a second main device 300 in a preset area and acquiring communication parameters of the second main device 300;
s200, generating a pre-association instruction according to the communication parameters of the second master device 300 and the communication parameters of the first master device 200;
s300, sending a pre-association instruction to the management center 400;
s400, receiving a pre-correlation result, wherein the pre-correlation result is generated by the management center 400 according to a pre-correlation instruction;
s500, disconnecting the communication connection between the slave device 100 and the first master device 200 according to the received pre-association result, and establishing the communication connection between the slave device 100 and the second master device 300.
In step S100, the preset area is an area that radiates a preset range to the surroundings with the position where the slave device 100 is located as a starting point, where the preset range is an area where the slave device can perform communication connection with the second master device, and the preset range can be customized according to requirements, so as to ensure that the slave device 100 can scan other master devices suitable for connection. The embodiment of the present invention is not limited to scanning one second master device 300, in practical applications, there may be several second master devices 300, and the embodiment of the present invention is discussed only with respect to one second master device 300. In practical applications, during the movement of the slave device 100, all the second master devices 300 in the predetermined area are scanned for performing roaming handover.
When a second master device 300 existing around is scanned and acquired in a preset area, a communication parameter of the second master device 300 is acquired, where the communication parameter is used to represent whether the scanned second master device 300 is suitable for the slave device 100 to perform communication connection; the communication parameters include: signal strength value, channel background noise value, and connection MCS (Modulation and Coding Scheme, modulation and Coding strategy) value, and the specific communication parameters may be obtained according to the requirements, and are not limited to the above parameter types. After the communication parameters of the second master device 300 are acquired, the communication parameters of the second master device 300 are sent to the management center 400 for storage, so as to be used for subsequent judgment of roaming switching conditions.
In some embodiments, before step S100, the roaming handover method further includes:
acquiring communication parameters of a first master device 200 in communication connection with the slave device 100;
comparing the communication parameter of the first master device 200 with a preset threshold value;

if the slave device 100 is determined to need to perform roaming handover, performing step S100; otherwise, ending the flow.
If the communication parameter of the first master device 200 is smaller than the preset threshold, which indicates that the communication connection state between the first master device 200 and the slave device 100 is not good, that is, the slave device 100 needs to perform roaming handover, acquiring the communication parameter of the second master device 300 scanned in step S100; if the communication parameter of the first master device 200 is greater than the preset threshold, it indicates that the communication connection state between the first master device 200 and the slave device 100 is good, that is, the slave device 100 does not need to perform roaming handover.
In some embodiments, the communication parameters of the first master device 200 include a signal strength value, a channel noise floor value and a connection MCS value, and a specific example of comparing the communication parameters of the first master device 200 with a preset threshold value may be that the signal strength value is lower than 65, the channel noise floor value is higher than 75, and the connection MCS value is lower than 3, when more than one of the three communication parameters does not satisfy the preset threshold value, it indicates that the communication connection state between the first master device 200 and the slave device 100 is not good, that is, the slave device 100 needs to perform roaming handover. In practical application, the size of the preset threshold can be modified according to practical situations.
In step S200, a pre-association command is generated according to the communication parameters of the second master device 300 and the communication parameters of the first master device 200 acquired in step S100, whether roaming handover is possible is determined according to the communication parameters of the second master device 300 and the communication parameters of the first master device 200, if a roaming handover condition is satisfied, the pre-association command is generated, and if the roaming condition is not satisfied, other second master devices 300 in a preset area are rescanned.
In some embodiments, generating the pre-association instruction according to the communication parameters of the second master device 300 and the communication parameters of the first master device 200 includes:
comparing the magnitude of the communication parameter of the second master device 300 with the magnitude of the communication parameter of the first master device 200, wherein the communication parameters include: signal strength value, channel background noise value, connection MCS value and the like;
judging whether roaming switching conditions are met or not by comparing the sizes of the communication parameters;
if the communication parameter of the second master device 300 is greater than the communication parameter of the first master device 200, generating a pre-association instruction;
if the communication parameter of the second master device 300 is smaller than the communication parameter of the first master device 200, the other second master devices 300 in the preset area are rescanned.
In practical applications, the comparison manner of the communication parameters may be customized according to specific situations, for example, all three types of communication parameters of the second master device 300 are greater than the type of communication parameters corresponding to the first master device 200, or any two types of communication parameters of the second master device 300 are greater than the type of communication parameters corresponding to the first master device 200, or any one type of communication parameters of the second master device 300 is greater than the type of communication parameters corresponding to the first master device 200, or the signal strength value of the second master device 300 is greater than the signal strength value of the first master device 200, which is not specifically limited in the embodiment of the present invention.
In an application example that may be implemented, as shown in fig. 3, the communication parameters of the first master device 200 are obtained in advance, whether roaming handover is required is determined according to the communication parameters of the first master device 200, if necessary, other second master devices 300 in a preset area are scanned, and if not, the communication parameters of the first master device 200 are obtained again according to the area location where the slave device 100 is located. When the second master device 300 is obtained by scanning, the communication parameters of the second master device 300 are obtained and stored, and if the second master device 300 is not obtained by scanning, the communication parameters of the first master device 200 are obtained again according to the area position of the slave device 100. Comparing the acquired communication parameters of the second main device 300 with the communication parameters of the first main device 200, judging whether the communication parameters of the second main device 300 are larger than the communication parameters of the first main device 200, if so, generating a pre-association instruction, and if not, rescanning other second main devices 300 in the preset area.
In step S300, a pre-association command is sent to the management center 400 according to the pre-association command, where the pre-association command is generated in step S200, and the slave device 100 sends the generated pre-association command to the management center 400 to inform the management center 400 of a pre-processing flow of roaming handover.
In step S400, after the slave device 100 transmits the pre-association command to the management center 400, the pre-association result generated by the management center 400 according to the pre-association command is received.
In some embodiments, the pre-association result is generated by a connection response instruction received by the management center 400, the connection response instruction is generated by the second master device 300 receiving a connection request instruction sent by the management center 400, and the connection request instruction is generated by the management center 400 according to the received pre-association instruction. After receiving the pre-association instruction of the slave device 100, the management center 400 generates a connection request instruction, and sends the connection request instruction to the second master device 300; after receiving the connection request instruction, the second master device 300 generates a connection response instruction according to the connection request instruction and sends the connection response instruction to the management center 400; the management center 400 generates a pre-association result according to the received connection response instruction, and transmits the pre-association result to the slave device 100.
In some embodiments, the sending, by the management center 400, the connection request instruction to the second master device 300 and receiving, by the second master device 300, the connection response instruction sent by the connection request instruction to generate the pre-association result includes: the pre-association result is generated by the management center 400 receiving an association response instruction sent by the second master device 300, the association response instruction is generated by the second master device 300 according to an association request instruction sent by the management center 400, the association request instruction is sent to the second master device 300 by the management center 400 according to an authentication response instruction, and the authentication response instruction is generated by the second master device 300 according to the authentication request instruction sent by the management center 400.
In some embodiments, the authentication request instruction includes a device parameter of the slave device 100, and the second master device 300 checks the device parameter, where in practical applications, the device parameter includes: the second master device 300 checks the device parameters, such as the physical address of the device and the device ID, to check the validity of the device parameters, and by checking the device parameters, the slave device 100 is guaranteed not to be harmful to the second master device 300, and it is also proven that the second master device 300 can be in communication connection with the slave device 100.
In some embodiments, the association request instruction includes an encrypted identifier of the slave device 100, the second master device 300 verifies the encrypted identifier, and in practical applications, the encrypted identifier is an identifier existing in a form of a secret key, and the second master device 300 verifies and decrypts the encrypted identifier to obtain a public key of the slave device 100, and when the slave device 100 is in communication connection with the second master device 300, the public key obtained through verification and decryption is paired with a private key existing in the slave device 100, so as to correctly establish communication connection.
In step S500, the communication connection between the slave device 100 and the first master device 200 is disconnected according to the received pre-association result, and the communication connection between the slave device 100 and the second master device 300 is established. The slave device 100, upon receiving the pre-association result, i.e. the pre-processing of the management center 400 to complete the roaming handover, informs the slave device 100 of the pre-association result.
