Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Referring to fig. 1, which is a schematic flow diagram of a frequency band selection method for a hybrid link according to the embodiment of the present invention, where the hybrid link includes a front-end device and a back-end device that are sequentially linked, the front-end device and the back-end device support a same preset frequency band, and the front-end device splits the preset frequency band into multiple sub-frequency bands, the method is executed by the front-end device, and the method includes: the method includes steps S1 to S2:
s1, when the device is not a control device, obtaining the working frequency band of the control device in the hybrid link;
and S2, if the working frequency band comprises at least one sub-frequency band, acquiring the frequency band synchronized by the back-end equipment from the control equipment, and adding the physical address of the back-end equipment to an access control list of the corresponding frequency band of the equipment so that the back-end equipment can scan the corresponding frequency band of the equipment and carry out bridging.
It should be noted that the hybrid link includes a front-end device and a back-end device that are sequentially linked, the front-end device and the back-end device support the same preset frequency band, and the front-end device splits the preset frequency band into a plurality of sub-frequency bands. For example, the front-end equipment and the back-end equipment both support all 5G frequency bands, including 5G band12 and band4, the channel corresponding to band1 is 36-48, the channel corresponding to band2 is 48-64, the channel corresponding to band4 is 149-165, and the front-end equipment further splits the 5G frequency band into a 5G1 frequency band (channel: 36-64) and a 5G4 frequency band (channel: 149-165). At this time, when the backend device synchronizes the 5G frequency band, the backend device switches back and forth between the 5G1 frequency band and the 5G4 frequency band, and the method is executed by the front-end device, and specifically includes the following steps:
firstly, judging whether the front-end equipment is the control equipment in the hybrid link or not, and determining different execution steps according to different judgment results.
When the equipment is not the control equipment, acquiring the working frequency band of the control equipment in the hybrid link;
if the operating frequency band of the Control device includes at least one sub-frequency band, that is, the Control device operates in the sub-frequency band, then the back-end device synchronizes to the sub-frequency band from the Control device and synchronizes to the sub-frequency band from the front-end device when the channels are synchronized, in order to avoid switching back and forth between different sub-frequency bands, the invention adopts a method of Access Control List (ACL) white list Control.
It should be noted that, in the Mesh mechanism of the wireless Mesh network, a white list logic of a paired ACL exists, and only when the front-end device fills the Abstract Layer MAC Address (ALMAC) of the back-end device RE into the self-driven paired ACL list, a Response frame (Probe Response frame) is returned to the back-end device RE, so that the back-end device RE can scan itself and bridge the Response frame.
Therefore, under the condition that the control device works in the sub-frequency band, the frequency band to which the back-end device synchronizes from the control device is obtained first, and the physical address of the back-end device is added to the access control list of the corresponding frequency band of the back-end device, so that the back-end device can scan the corresponding frequency band of the back-end device and perform bridging, and the synchronous frequency band of the back-end device from the back-end device is ensured to be completely the same as the synchronous frequency band of the slave control device. It should be noted that, if the physical address of the back-end device is written on the access control list of other frequency bands of the device at this time, corresponding deletion needs to be performed, so as to avoid bridging the back-end device to the front-end device through other frequency bands.
To further the understanding of this embodiment of the present invention, two examples are described below, with schematic views referring to fig. 2 and 3.
In fig. 2, the front-end device supports 2G, 5G1, and 5G4 frequency bands, the operating frequency band of the control device is a 2G +5G1 frequency band or a 2G +5G4 frequency band, the back-end device supports 2G and 5G frequency bands, the frequency band to which the back-end device synchronizes from the control device is a 2G +5G1 frequency band or a 2G +5G4 frequency band, and correspondingly, the front-end device should add a physical address of the back-end device to an access control list of the 2G +5G1 frequency band or the 2G +5G4 frequency band of the device.
In fig. 3, the front-end device supports 2G, 5G1, and 5G4 frequency bands, the operating frequency bands of the control device are 2G, 5G1, and 5G4 frequency bands, the back-end device supports 2G frequency bands and 5G frequency bands, the frequency bands to which the back-end device synchronizes from the control device are 2G frequency bands and 5G1 frequency bands, and at this time, the front-end device should add the physical address of the back-end device on the access control list of the 2G +5G1 frequency band of the device.
It is to be noted that, in a network communication link, each network device may obtain frequency bands of other network devices and channels corresponding to the frequency bands through topology learning of 1905 message interactive learning, for example, the working frequency bands of the control device CAP are 2G, 5G1, and 5G4, and although the backend device is not directly linked to the control device CAP, the backend device may also obtain these information through topology learning.
The embodiment of the present invention provides a method for selecting a frequency band of a hybrid link, where a frequency band synchronized by a back-end device from a control device is obtained, and a physical address of the back-end device is added to an access control list of a corresponding frequency band of the back-end device, so that the back-end device can scan and bridge the corresponding frequency band of the back-end device, thereby avoiding a problem that the back-end device switches back and forth between different frequency sub-bands when the frequency bands are synchronized, and ensuring that the frequency band of the back-end device in the hybrid link is stable.
As an improvement of the above scheme, the method further comprises the following steps:
if the working frequency band does not comprise any sub-frequency band, adding a physical address of the back-end equipment on an access control list of the corresponding frequency band of the equipment according to a preset frequency band declaration strategy of the equipment so that the back-end equipment can scan the corresponding frequency band of the equipment and carry out bridging; alternatively, the first and second electrodes may be,
determining the frequency band to be synchronized by the back-end equipment according to the frequency band selection strategy preset by the back-end equipment, and adding the physical address of the back-end equipment to the access control list of the corresponding frequency band of the back-end equipment so that the back-end equipment can scan the corresponding frequency band of the back-end equipment and carry out bridging.
Specifically, if the operating frequency band of the control device does not include any sub-frequency band, the control device does not operate in any sub-frequency band. For example: the front-end device supports 2G, 5G1, and 5G4 frequency bands, the operating frequency band of the control device is a 2G +6G frequency band, and the back-end device supports 2G and 5G frequency bands, so that the operating frequency band of the control device does not include any sub-frequency bands (5G1 frequency band and 5G4 frequency band).
In this case, the physical address of the back-end device is added to the access control list of the corresponding frequency band of the device according to the frequency band declaration policy preset by the device, so that the back-end device can scan the corresponding frequency band of the device and perform bridging, thereby guiding the back-end device to select the same sub-frequency band as the front-end device. For example, if the frequency band advertisement policy preset by the front end device is to advertise the frequency bands of the front end device as 2G and 5G4 frequency bands, the physical address of the back end device is added to the access control list of the 2G and 5G4 frequency bands of the front end device, so that the back end device is guided to scan the 2G and 5G4 frequency bands of the front end device for bridging. Alternatively, the first and second electrodes may be,
determining the frequency band to be synchronized by the back-end equipment according to a frequency band selection strategy preset by the back-end equipment, and adding a physical address of the back-end equipment to an access control list of the corresponding frequency band of the back-end equipment so that the back-end equipment can scan the corresponding frequency band of the back-end equipment and perform bridging, which is the preset selection of the back-end equipment by the front-end equipment and keeps consistent with the back-end equipment. Generally, the frequency band selection policy preset by the backend device is as follows: when the backend device performs frequency band synchronization with other devices, if there are multiple sub-frequency bands that can be selected, the first sub-frequency band is synchronized. For example, the backend device supports a 2G band and a 5G band, but the 5G band has two selectable bands, namely a 5G1 band and a 5G4 band, and at this time, the backend device defaults to synchronize the 5G1 band, and at this time, in order to keep consistency, the front end device adds a physical address of the backend device to an access control list of the 2G and 5G1 bands of the front end device, so that the backend device is guided to scan the 2G and 5G1 bands of the front end device for bridging.
As an improvement of the above scheme, the method further comprises the following steps:
when the device is a control device of the hybrid link, adding a physical address of the back-end device on an access control list of a corresponding frequency band of the device according to a frequency band declaration strategy preset by the device, so that the back-end device can scan the corresponding frequency band of the device and carry out bridging; alternatively, the first and second electrodes may be,
determining the frequency band to be synchronized by the back-end equipment according to the frequency band selection strategy preset by the back-end equipment, and adding the physical address of the back-end equipment to the access control list of the corresponding frequency band of the back-end equipment so that the back-end equipment can scan the corresponding frequency band of the back-end equipment and carry out bridging.
Specifically, when the device is a control device of a hybrid link, two ways of synchronization of the slave control device and synchronization of the front-end device are the same way for the back-end device, and no conflict occurs.
At this time, the front-end device may add a physical address of the back-end device to the access control list of the corresponding frequency band of the device according to the frequency band declaration policy preset by the device, so that the back-end device can scan and bridge the corresponding frequency band of the device; alternatively, the first and second electrodes may be,
and determining the frequency band to be synchronized by the back-end equipment according to a frequency band selection strategy preset by the back-end equipment, and adding a physical address of the back-end equipment to an access control list of the corresponding frequency band of the back-end equipment so that the back-end equipment can scan the corresponding frequency band of the back-end equipment and carry out bridging.
The access control logic of this embodiment is similar to the previous embodiment: the situation that the operating band of the control device does not include any sub-band is similar, and is not described herein again.
As an improvement of the above scheme, before adding the physical address of the backend device to the access control list of the corresponding frequency band of the device, the method further includes:
traversing pairing equipment in a configuration list of the equipment to acquire a physical address of the pairing equipment; wherein the paired device comprises the backend device.
Specifically, traversing paired equipment in a configuration list of the equipment to acquire a physical address of the paired equipment; wherein the pairing device comprises a backend device. Generally, after the front-end device is powered on and receives the WLAN Ready event, the front-end device traverses all other paired devices in the configuration list, and meanwhile, each network device can support at least a 2G frequency band, so the ALMAC of each paired device can be preferentially added to the paired ACL list of the 2G frequency band of the front-end device. At this time, because the channel value of the 5G frequency band of the back-end device RE is unknown, in order to avoid bridging of the dual-frequency RE to the front-end device on an unexpected sub-frequency band, ACL additions of 5G1 and 5G4 may be skipped first, so as to avoid the back-end device RE scanning Basic Service Set (BSS) entries of the front-end device on the 5G frequency band, and after learning the actual frequency band of the back-end device RE, the ACL entries of the back-end device RE are updated again on the 5G1 frequency band or the 5G4 frequency band corresponding to the front-end device RE.
