Description

Technical Field

[0001] The present invention relates to the technical field of optical network communication, and particularly to a channel management method, apparatus, device, system, and storage medium. Background Art

[0002] In the existing Gigabit Passive Optical Network (G / EPON) management model, the Internet access service configuration for Optical Network Units (ONUs) is mainly in a Point-to-Point (P2P) manner, that is, wireless parameters are configured separately for each ONU. As there are more and more Internet-connected intelligent devices nowadays, on the one hand, the efficiency of configuring wireless parameters in the P2P manner is low; on the other hand, there are more and more wireless router devices accessing the channel, and the congestion degree of the channel is getting higher and higher.

[0003] The channel transmission speed is affected by the complex environment of the surrounding Wireless Fidelity (WIFI). If the channel used by a user for WIFI signal overlaps with the channel of a certain WIFI signal around, it will cause interference. Therefore, the wireless router device needs to frequently switch channels. However, the existing channel switching methods usually directly select the currently best-signal channel and then switch. However, the congestion situation of the signal changes very rapidly. If the best-quality channel is directly selected each time, the channel switching will be quite frequent, reducing the service life of the routing device.

[0004] In the environment of Fiber to The Room (FTTR), multiple ONUs enter the user's home, bringing high bandwidth and large-capacity support capabilities of the fiber channel while meeting the current mainstream home entertainment and interconnection needs. However, there is currently no effective solution for batch wireless management of multiple ONUs, improving the Internet speed and stability of Wireless Local Area Network (WLAN) access, simplifying the wireless configuration process of ONUs, and realizing the collaborative and interconnection requirements of multiple ONUs based on traditional management means.

[0058] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the following will further describe the specific technical solutions of the invention in detail with reference to the accompanying drawings in the embodiments of the present invention. The following embodiments are used to illustrate the present invention but are not used to limit the scope of the present invention.

[0059] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0060] Figure 1 Schematic flowchart of a channel management method provided by an embodiment of the present invention. As Figure 1 shown, the method is applied to a channel management system, the system includes at least one virtual domain, a virtual management node is set in a first virtual domain among the at least one virtual domain; the virtual management node manages multiple optical network units ONUs; the first virtual domain is any one of the at least one virtual domain; the method includes:

[0061] S101: When at least one first ONU is successfully registered, obtain first information related to a channel reported by each of the first ONUs; the first ONU is any one of the multiple ONUs;

[0062] It should be noted that the channel management system mentioned here can be an ONU channel management system. As an example, the ONU channel management system can be an ONU channel management system within the FTTR domain. The at least one virtual domain can be understood as one virtual domain or multiple virtual domains. This virtual domain can be a virtualized domain and can be created through an Optical Line Terminal (OLT). As an example, this virtual management node can correspond to the virtual domain. The virtual management node managing multiple Optical Network Units (ONUs) can be understood as the virtual management node can uniformly manage multiple ONUs belonging to the virtual domain corresponding to this virtual management node. In practical applications, the multiple ONUs can be deployed in the same user's home, and the specific number of ONUs can be determined according to the actual situation and is not limited here. As an example, the specific number of ONUs can be 4, and one can be deployed in each room of the same user's home.

[0063] In the case where at least one first ONU is successfully registered, obtaining the first information related to the channel reported by each of the first ONUs can be understood as after the first ONU completes the registration authorization and joins the virtual domain, the virtual management node obtains the first information related to the channel reported by the first ONU; among them, the virtual management node can be a WIFI management node; the first information can be any information related to the channel used by the first ONU and is not limited here. As an example, the first information can at least include the signal strength of the channel used by the first ONU, the number of devices in the channel, and the data traffic value; the number of the first ONUs can be multiple; the process of registration authorization can be determined according to the actual situation and is not limited here. As an example, the process of registration authorization can be the registration authorization carried out by the standard G / EPON.

[0064] For the convenience of understanding, here is an example of an actual application scenario. Under the OLT view, configure the ONU domain ID and the corresponding WIFI management node. After the ONU completes the standard G / EPON registration authorization, it joins the virtual domain.

[0065] S102: Determine the channel maintenance information within the first virtual domain according to the first information;

[0066] It should be noted that the channel maintenance information can be an in-domain channel maintenance table containing channel information and is not limited here. As an example, the channel maintenance information can be an in-domain channel maintenance table including the number of devices in each channel, channel strength, and channel quality ranking.

[0067] Determining the channel maintenance information within the first virtual domain according to the first information can be to count the signal strength of the channels used by multiple ONUs and the number of devices in the channels into an in-domain channel maintenance table.

[0068] S103: Allocate a target channel to the first ONU based on the channel maintenance information.

[0069] It should be noted that the target channel can be a channel with the least interference and the strongest signal, which is not limited here. As an example, the target channel can be a channel with the least interference. When the interference levels of channels are the same, it can be a channel with a stronger signal strength.

[0070] Allocating a target channel to the first ONU based on the channel maintenance information can be that the virtual management node allocates the channel with the least interference to the first ONU according to the number of devices, channel strength, and channel quality ranking in each channel within the virtual domain.

[0071] The channel management method provided by the embodiments of the present invention can eliminate WIFI channel conflicts and improve channel bandwidth utilization by setting a virtual management node within the virtual domain. The virtual management node determines the channel maintenance information within the virtual domain according to the first information reported by the first ONU, and allocates a target channel to the first ONU based on the channel maintenance information.

[0072] In an alternative embodiment of the present invention, the method further includes: configuring the attribute information of the first virtual domain.

[0073] It should be noted that the attribute information can be virtual domain identity information (ID, Identity Document), domain user name, account password, encryption method, service model, domain status, and other information.

[0074] Configuring the attribute information of the first virtual domain can be that the OLT creates a virtual domain and configures the domain ID, domain user name, and account password in the OLT view.

[0075] In an alternative embodiment of the present invention, the attribute information includes the signal configuration information of the management node; in the case where at least one first ONU is successfully registered, the method further includes: obtaining the signal configuration information; configuring the signal configuration information to each of the first ONUs.

[0076] It should be noted that the signal configuration information can be the wireless configuration of the virtual management node. As an example, the signal configuration information can be the WIFI configuration and WIFI channel configuration of the virtual management node. The signal configuration information of the management node can be understood as the WIFI configuration and WIFI channel configuration set by the OLT for the virtual management node.

[0077] When at least one first ONU is successfully registered, the method further includes: obtaining the signal configuration information; configuring the signal configuration information to each of the first ONUs. It can be understood that when an ONU in the virtual domain completes the standard G / EPON registration authorization, the virtual management node performs WIFI channel allocation for the ONU.

[0078] Figure 2 FIG. is a schematic diagram of a virtual domain including the multiple first ONUs in the channel management method according to an embodiment of the present invention. The first ONU can be any one of the multiple ONUs in the virtual domain, such as Figure 2 As shown, ONU 1 [first ONU], ONU 2 [first ONU], ONU 3 [first ONU], and ONU 4 [first ONU] are displayed in the virtual domain.

[0079] In an alternative embodiment of the present invention, the attribute information includes the initial channel maintenance table of the first virtual domain; the first information includes the access quantity and signal strength of the terminals corresponding to the channels used by each of the first ONUs; the determining the channel maintenance information in the first virtual domain according to the first information includes: determining the first content in the initial channel maintenance table according to the access quantity and signal strength of the terminals corresponding to the channels used by each of the first ONUs; determining the channel maintenance information in the first virtual domain based on the first content.

[0080] It should be noted that the initial channel maintenance table can be a corresponding in-domain channel maintenance table generated when the OLT configures WIFI for the virtual management node. As an example, the initial channel maintenance table can be an in-domain channel maintenance table with an empty initial state.

[0081] Determining the first content in the initial channel maintenance table according to the access quantity and signal strength of the terminals corresponding to the channels used by each of the first ONUs; determining the channel maintenance information in the first virtual domain based on the first content can be understood as the virtual management node determines the updated content of the initial channel maintenance table according to the access quantity and signal strength of the terminals corresponding to the channels used by each ONU, and counts the new in-domain channel maintenance table according to the updated content.

[0082] In an alternative embodiment of the present invention, determining the first content in the initial channel maintenance table according to the number of terminal accesses and signal strength of each of the first ONUs using a channel includes: determining an interference parameter corresponding to each of the first ONUs using a channel according to the number of terminal accesses of the terminals corresponding to each of the first ONUs using a channel; determining the channel quality corresponding to each of the first ONUs using a channel based on the interference parameter and the signal strength of the terminals corresponding to each of the first ONUs using a channel; and using the number of accesses, the interference parameter, the signal strength, and the channel quality as the first content.

[0083] It should be noted that determining an interference parameter corresponding to each of the first ONUs using a channel according to the number of terminal accesses of the terminals corresponding to each of the first ONUs using a channel can be understood as the virtual management node determining the interference magnitude of the corresponding channel according to the number of terminal accesses of the channel reported by the ONU; determining the channel quality corresponding to each of the first ONUs using a channel based on the interference parameter and the signal strength of the terminals corresponding to each of the first ONUs using a channel can be understood as determining the quality of the corresponding channel according to the interference magnitude and signal strength of the channel used by the ONU; and using the number of accesses, the interference parameter, the signal strength, and the channel quality as the first content can be understood as the virtual management node using the number of terminal accesses, the channel interference magnitude, the signal strength, and the channel quality of the channel used by the ONU as the content for updating the channel maintenance table within the domain.

[0084] In an alternative embodiment of the present invention, determining the channel maintenance information within the first virtual domain based on the first content includes: sorting the values of the number of accesses, the interference parameter, the signal strength, and the channel quality corresponding to each of the multiple first ONUs using a channel respectively to obtain a sorting result; and determining the channel maintenance information within the first virtual domain according to the sorting result.

[0085] It should be noted that sorting the values of the number of accesses, the interference parameter, the signal strength, and the channel quality corresponding to each of the multiple first ONUs using a channel respectively to obtain a sorting result can be understood as the virtual management node sorting the number of accesses, the interference magnitude, the signal strength, and the channel quality corresponding to the channels used by multiple ONUs respectively, arranging them in ascending order of interference magnitude, and when the interference magnitudes are the same, arranging them according to the signal strength, with the greater signal strength ranked first; and determining the channel maintenance information within the first virtual domain according to the sorting result can be understood as the virtual management node generating a new channel maintenance table within the domain according to the sorting result.

[0086] In an alternative embodiment of the present invention, the step of allocating a target channel to the first ONU based on the channel maintenance information includes: obtaining target channel maintenance information based on the channel maintenance information; the target channel maintenance information represents information corresponding to channels that do not interfere with each other and whose channel quality values are greater than a preset threshold; determining the target channel corresponding to the target channel maintenance information; and allocating the target channel to the first ONU.

[0087] It should be noted that obtaining target channel maintenance information based on the channel maintenance information can be understood as the virtual management node selecting all channels within the domain according to the in-domain channel maintenance table; the target channel maintenance information representing information corresponding to channels that do not interfere with each other and whose channel quality values are greater than a preset threshold can be understood as the virtual management node selecting multiple channels that are interference-free with each other and whose channel quality meets the requirements; determining the target channel corresponding to the target channel maintenance information and allocating the target channel to the first ONU can be understood as the virtual management node determining several channels with low interference levels according to the selection result and allocating the channels to the corresponding ONUs within the virtual domain.

[0088] In an alternative embodiment of the present invention, when at least one first ONU is successfully registered, the method further includes: configuring first time parameter, second time parameter, and third time parameter of the virtual management node.

[0089] It should be noted that the first time parameter can be a query time parameter. As an example, the first time parameter can be the time when the virtual management node sends a first query message to the first ONU; the second time parameter can be a waiting time parameter. As an example, the second time parameter can be the time when the virtual management node waits for the first ONU to respond to the first query message; the third time parameter can be a waiting time parameter. As an example, the third time parameter can be the time when the virtual management node waits for the first ONU to respond to the query message.

[0090] Configuring the first time parameter, second time parameter, and third time parameter of the virtual management node can be understood as when the OLT creates a virtual management node corresponding to the virtual domain, it can configure the time when the virtual management node sends a first query message to the first ONU, the time when it waits for the first ONU to respond to the first query message, and the time when it waits for the first ONU to respond to the query message.

[0091] In an alternative embodiment of the present invention, the method further includes: sending a first query request to the first ONU within a first preset time; the first preset time is determined based on the first time parameter; receiving first response information from the first ONU based on the first query request within a second preset time; the second preset time is determined based on the second time parameter.

[0092] It should be noted that the first query request may be a query message sent by the virtual management node to the ONU within the domain to scan the surrounding wireless networks, detect the signal strength of the used channels, and the number of terminal accesses; the first response information can be understood as the first response message reported by the ONU to the virtual management node.

[0093] Sending the first query request to the first ONU within the first preset time can be understood as the virtual management node sending the first query message to scan the surrounding wireless networks, detect the signal strength of the used channels, and the number of terminal accesses to the ONU within the domain according to the preset query time; receiving the first response information of the first ONU based on the first query request within the second preset time can be understood as the virtual management node receiving the first response message reported by the ONU within the preset waiting time.

[0094] In an alternative embodiment of the present invention, the method further includes: sending a second query request to the first ONU when the first response information is not received within the second preset time; determining that the status of the first ONU is a disconnected state when the second response information of the first ONU based on the second query request is not received within the third preset time; the third preset time is determined based on the third time parameter.

[0095] It should be noted that the second query request may be a second query message sent by the virtual management node to the ONU within the domain; the second response information may be a second response message sent by the ONU to the virtual management node.

[0096] Sending the second query request to the first ONU when the first response information is not received within the second preset time can be understood as the virtual management node sending a second query message to the corresponding ONU when the first response message reported by the ONU is not received within the preset waiting time; determining that the status of the first ONU is a disconnected state when the second response information of the first ONU based on the second query request is not received within the third preset time can be understood as the virtual management node considering the corresponding ONU to be disconnected when the second response message reported by the ONU is not received within the preset waiting time.

[0097] For better understanding, an application scenario is exemplified here. In a virtual domain, the management node maintains heartbeat detection with the members in the domain through the VRCP protocol. The management node periodically sends query messages encapsulated by the VRCP protocol, and the ONU periodically reports response messages. The response messages contain the scanned surrounding WIFI information, the number of client accesses, and the data traffic value. When the management node does not receive the response message reported by the ONU within the waiting time set in the heartbeat message, it sends a specific query message encapsulated by the VRCP protocol to the ONU to confirm again whether the member in the domain is disconnected. If no response message from the member is received after n queries, where n can be configured, it is considered that the ONU is disconnected. At this time, the management node can reclaim the WIFI channel and update the channel maintenance table in the domain, and reallocate the channel.

[0098] In an alternative embodiment of the present invention, the method further includes: configuring a priority parameter of the virtual management node according to the data traffic of the channel used by the first ONU or the number of accesses of the corresponding terminal; the priority parameter is used to schedule the target channel.

[0099] It should be noted that configuring the priority parameter of the virtual management node according to the data traffic of the channel used by the first ONU or the number of accesses of the corresponding terminal can be understood as the OLT setting the data traffic of the channel used by the ONU or the number of accesses of the corresponding terminal as the priority condition for the virtual management node to allocate the target channel; the priority parameter is used to schedule the target channel can be understood as the virtual management node determining the allocation priority of the target channel according to the size of the data traffic of the channel used by the ONU, or the virtual management node determining the allocation priority of the target channel according to the size of the number of accesses of the terminal corresponding to the channel used by the ONU.

[0100] In an alternative embodiment of the present invention, when there is a situation where the first ONU exits in the first virtual domain, the method further includes: obtaining the channel used by the exited first ONU; updating the status of the channel used by the exited first ONU in the channel maintenance information to obtain the updated channel maintenance information; and reallocating the target channel to the first ONU based on the updated channel maintenance information.

[0101] It should be noted that when a first ONU exits in the first virtual domain, it can be understood that the ONU exits from the virtual domain; obtaining the used channel corresponding to the exited first ONU can be understood that the virtual management node determines the channel used by the exited ONU; updating the status of the used channel corresponding to the exited first ONU in the channel maintenance information to obtain the updated channel maintenance information can be understood as updating the status of the channel used by the exited ONU in the channel maintenance table. As an example, the status of the used channel can be changed from the in-use status to the idle status; reassigning the target channel to the first ONU based on the updated channel maintenance information can be understood as reassigning channels to the ONUs within the domain according to the updated channel maintenance table.

[0102] An embodiment of the present invention provides a channel management method. When at least one first ONU is successfully registered, the method obtains first information related to channels reported by each of the first ONUs; the first ONU is any one of the multiple ONUs; determines channel maintenance information within the first virtual domain according to the first information; and assigns a target channel to the first ONU based on the channel maintenance information. This method can be used in FTTR in a multi-ONU scenario, adding multiple physical ONUs under a single user's home to an ONU domain, setting up a virtual management node in the ONU domain, and using the virtual management node to perform WIFI configuration and channel management on the ONUs within the virtual domain, achieving batch management of wireless channels, simplifying the configuration process, eliminating WIFI conflicts, improving channel bandwidth utilization, and ensuring a good Internet access environment and speed in multiple wireless network coverage areas.

[0103] To understand the embodiments of the present invention, a specific application scenario of a channel management method is exemplified in the embodiments of the present invention, and the specific process is as follows:

[0104] The first step: The OLT first creates an ONU domain, configures attributes such as the domain ID, domain user name, account password, encryption method, service model, etc., and the initial state of the domain is idle;

[0105] The second step: The OLT performs WIFI configuration on the WIFI management node of the virtual domain and simultaneously generates a channel maintenance table within the domain, which is an empty table in the idle state;

[0106] The third step: The ONU completes standard G / EPON registration authorization and joins the virtual domain, obtains and automatically synchronizes the WIFI configuration from the virtual WIFI management node, and the WIFI channel configuration is directly assigned by the WIFI management node;

[0107] Step 4: Configure the time for the WIFI management node to send query messages and the response message time parameters for the virtual member to report the surrounding WIFI information, the number of client accesses and the data traffic value, and the time for sending the specific query message encapsulated by the VRCP protocol to the specific virtual member and the corresponding response message time parameters;

[0108] Step 5: The intra-domain channel maintenance table is updated according to the parameters reported by other members in step 4. The user configures the channel allocation refresh time in the intra-domain channel maintenance table, checks the channel status at each refresh time, and reallocates if there is any change. The user configures the number of client accesses and data traffic values as different priorities for scheduling.

[0109] Step 6: Finally, you can query the virtual domain information in the OLT view, including the domain ID, domain user name, status, management node WIFI configuration, and domain channel maintenance table.

[0110] In the embodiment of the present invention, based on the virtual framework of the FTTR home networking management entity, multiple physical ONUs under a single user's home are added to an ONU domain, and the wireless configuration of multiple physical ONUs is indirectly managed by virtualizing a controlled object (virtual management node). The configuration object is no longer a specific ONU, but a virtual management node, thereby simplifying the wireless configuration process and facilitating maintenance and management.
