Description

Communication method, system, storage medium and electronic device for gateway device

[0001] This disclosure claims priority to the Chinese patent application filed with the China Patent Office on July 14, 2023, with application number 202310867400.1 and invention name “Communication method, system, storage medium and electronic device for gateway equipment”, the entire content of which is incorporated by reference into this disclosure. Technical Field

[0002] The present disclosure relates to the field of communications, and in particular to a communication method, system, storage medium, and electronic device for a gateway device. Background Art

[0003] FTTR, or fiber to the room, primarily uses a P2MP (point to multiple point) network architecture. As shown in Figure 1, the main FTTR unit (MFU) connects to multiple sub-FTTR units (SFUs) through an indoor fiber distribution network (IFDN).

[0004] China's three major operators are deploying FTTR on a large scale. Since the standard has not yet been officially finalized, the PON (Passive Optical Network) network architecture shown in Figure 2 has an OLT (Optical Line Terminal) connected to multiple ONUs (Optical Network Units) via an ODN (Optical Distribution Network). FTTR's P2MP architecture is similar to PON. Therefore, currently deployed FTTR is primarily based on the industry's mature GPON (Gigabit Passive Optical Network) standard, using a 2.5G downstream rate and a 1.25G upstream rate.

[0005] Standards organizations such as CCSA (China Communications Standards Association) and ITU (International Telecommunications Union) are standardizing FTTR. Considering the needs of intra-home interconnection, they mainly adopt symmetrical 2.5G speeds, which will be upgraded to symmetrical 10G speeds in the future. For the symmetrical 2.5G speed, compatibility with existing deployed FTTR is required.

[0006] Regarding related technologies, there is currently no effective solution for achieving adaptive compatibility between symmetric 2.5G FTTR and existing asymmetric 2.5G FTTR.

[0007] Therefore, it is necessary to improve the related technology to overcome the above-mentioned defects in the related technology.

[0008] Summary of the Invention

[0028] FIG4 is a flow chart of a communication method of a gateway device according to an embodiment of the present disclosure. As shown in FIG4 , the method includes the following steps:

[0029] Step S402, determining a target operating mode of the slave gateway device according to the uplink rate supported by the master gateway device and the uplink rate supported by the slave gateway device;

[0030] Step S404: the slave gateway device communicates with the master gateway device according to the target working mode.

[0031] The embodiment of the present disclosure determines the target operating mode of the slave gateway device based on the uplink rate supported by the master gateway device and the uplink rate supported by the slave gateway device; the slave gateway device communicates with the master gateway device according to the target operating mode, thereby solving the technical problem of how to achieve adaptive compatibility between symmetric 2.5G FTTR and existing asymmetric 2.5G FTTR.

[0032] The master gateway device may be referred to as the master gateway, and the slave gateway device may be referred to as the slave gateway.

[0033] Among them, the master gateway MFU in the FTTR can send its own capabilities to the slave gateway SFU, and inform the slave gateway of the rate supported by the master gateway itself in the uplink direction, that is, the uplink rate.

[0034] Optionally, the master gateway can send its capabilities via a serial number request. The uplink rate can also be indicated via PLOAM broadcast, for example, by setting and sending information in an extended Upstream_Overhead message. The slave gateway can check the values ​​of the relevant fields to determine the master gateway's capabilities.

[0035] Optionally, when the Alloc-ID of the serial number request is 254, it indicates that the MFU supports an uplink rate of 1.25G.

[0036] The Alloc-ID (Allocation Identifier) ​​is a unique identifier in the GPON (Gigabit Passive Optical Network) standard used to identify the transmission container allocated to the Optical Network Unit (ONU). The OLT allocates bandwidth to the transmission container so that the ONU can obtain upstream transmission opportunities.

[0037] The value range of Alloc-ID is 0-4095, of which 0-252 are default allocation values, which are consistent with the ONU ID. 253, 254, and 255 are reserved broadcast values ​​for ONU activation. Other values ​​are used to allocate to different ONU transmission containers.

[0038] Among them, the function of Alloc-ID is to distinguish different ONU devices and their corresponding transmission containers in the GPON network.

[0039] When the Alloc-ID of the serial number request is 254, it indicates that the MFU supports an uplink rate of 1.25G, which is specified in the existing GPON standard.

[0040] Optional: When the Alloc-ID of the serial number request is 255, it indicates that the MFU supports a 2.5G uplink rate.

[0041] Optionally, when the Alloc-ID of the serial number request is 253, it indicates that the MFU supports 1.25 GHz and 2.5 GHz uplink rates.

[0042] Optionally, the 2.5G FTTR master gateway can alternately send serial number requests with Alloc-IDs of 255 and 254, or can send a single serial number request with Alloc-ID of 253, indicating that it supports both 1.25G and 2.5G uplink rates. The following embodiments use the alternate sending of serial number requests with Alloc-IDs of 255 and 254 as an example. These embodiments can also be modified to send a single serial number request with Alloc-ID of 253, and the process is similar. The 2.5G FTTR master gateway can also send a single serial number request with Alloc-IDs of 255 or 254, indicating that it only supports 2.5G uplink rates or 1.25G uplink rates.

[0043] Optionally, the 1.25G FTTR master gateway generally sends a serial number request with an Alloc-ID of 254.

[0044] Optionally, the master gateway may also send its own capabilities by filling in corresponding values ​​in relevant fields through PLOAM messages or other methods. For details, see the implementation method.

[0045] Among them, FTTR obtains the capabilities of the FTTR main gateway MFU from the gateway SFU, and determines its own working mode according to the uplink rate it supports.

[0046] For example, the FTTR slave gateway obtains the Alloc-ID carried in the serial number request sent by the FTTR master gateway to obtain the capabilities of the FTTR master gateway and determine its own working mode.

[0047] Optionally, for a 2.5G FTTR slave gateway, if it can receive a serial number request with an Alloc-ID of 255 or 253, it operates in 2.5G mode; if it can only receive a serial number request with an Alloc-ID of 254, it decelerates and operates in 1.25G mode.

[0048] Optionally, for a 1.25G FTTR slave gateway, if it receives a serial number request with an Alloc-ID of 254 or 253, it responds in 1.25G mode and does not respond to a serial number request with an Alloc-ID of 255.

[0049] Optionally, the FTTR slave gateway may also obtain the capability of the master gateway by checking corresponding values ​​of relevant fields in PLOAM messages or other methods. For details, see the implementation method.

[0050] Through the above embodiments, the 2.5G FTTR master gateway can be compatible with the 1.25G slave gateway, and the 2.5G FTTR slave gateway can also work at a reduced speed on the 1.25G FTTR master gateway.

[0051] In an exemplary embodiment, before executing the above step S402, a message field can also be determined from the gateway message sent by the master gateway device; and the target uplink rate indicated by the channel identifier carried in the message field is determined as the uplink rate supported by the master gateway device.

[0052] In an exemplary embodiment, the gateway message sending method includes at least one of the following: the master gateway device periodically sends the gateway message, wherein the periodically sent gateway message has the same or different channel identifiers; the master gateway device alternately sends the gateway message, wherein the alternately sent gateway messages have different channel identifiers.

[0053] In an exemplary embodiment, before determining the target uplink rate indicated by the channel identifier carried by the message field as the uplink rate supported by the master gateway device, a technical solution is further proposed, specifically including: when it is determined that the master gateway device is operating in a first operating mode, determining the first uplink rate corresponding to the first operating mode as the target uplink rate, and setting the channel identifier carried by the message field to the first identifier used to represent the uplink rate of the first operating mode; when it is determined that the master gateway device is operating in a second operating mode, determining the second uplink rate corresponding to the second operating mode as the target uplink rate, and setting the channel identifier carried by the message field to the second identifier used to represent the uplink rate of the second operating mode; when it is determined that the master gateway device is operating in the first operating mode and the second operating mode, determining the first uplink rate corresponding to the first operating mode and the second uplink rate corresponding to the second operating mode as the target uplink rate, and setting the channel identifier carried by the message field to the third identifier used to represent the uplink rates of the first operating mode and the second operating mode; wherein, the second uplink rate is greater than the first uplink rate.

[0054] In an exemplary embodiment, for the implementation process of determining the target operating mode of the slave gateway device based on the uplink rate supported by the master gateway device and the uplink rate supported by the slave gateway device, the specific steps include: obtaining all operating modes supported by the slave gateway device; wherein each of all the operating modes corresponds to an uplink rate; and determining the target operating mode that supports the target uplink rate from all the operating modes.

[0055] Optionally, the intersection of all operating modes supported by the slave gateway device and all operating modes supported by the master gateway device may be taken to obtain an operating mode set, and the optimal operating mode may be selected from the operating mode set as the target operating mode. For example, the operating mode with the highest uplink rate in the operating mode set may be determined as the target operating mode to increase uplink transmission capacity and reduce uplink transmission delay, or the operating mode with the lowest uplink rate in the operating mode set may be determined as the target operating mode to reduce energy consumption required for uplink transmission, etc. If there is only one operating mode in the operating mode set, this operating mode is determined as the target operating mode.

[0056] In an exemplary embodiment, multiple technical solutions are proposed for determining a target operating mode that supports the target uplink rate from all the operating modes, including:

[0065] Optionally, in an exemplary embodiment, the manner in which the message field carries the channel identifier includes at least one of the following: carrying the channel identifier through a sequence number request field; carrying the channel identifier through a PLOAM field.

[0066] This embodiment also includes Scheme 9, which includes determining extended burst length information from the PLOAM field when the channel identifier is carried by the PLOAM field; determining a target uplink rate indicated by the channel identifier carried by the message field, and determining a target operating mode of the slave gateway device that supports the target uplink rate. The steps of determining the target uplink rate indicated by the channel identifier carried by the message field and determining the target operating mode of the slave gateway device that supports the target uplink rate include: determining the target uplink rate indicated by the extended burst length information and determining the target operating mode of the slave gateway device that supports the target uplink rate.

[0067] Optionally, in this embodiment, a target uplink rate indicated by the extended burst length information may be determined, and a target operating mode of the slave gateway device that supports the target uplink rate may be determined from all the operating modes.

[0069] In an exemplary embodiment, after the above step S404, it is also possible to respond to a startup instruction for starting the slave gateway device, obtain an activation process preset for the slave gateway device, and activate the slave gateway device according to the activation process.

[0070] Next, the communication method of the gateway device is further described in conjunction with the following embodiments.

[0071] The following are the real-time preparations for the communication method of the gateway device in this disclosure:

[0072] Currently, the FTTR standards of CCSA and ITU-T are mainly modified and improved based on the GPON and XGS-PON (10-Gigabit-capable symmetric passive optical network) standards. The following expansion takes GPON as an example.

[0073] The results of modifying the Alloc-ID of the GPON standard are shown in Table 1 below. The modification mainly extends the Alloc-ID of the serial number request.

[0074] Table 1 Alloc-ID information table

[0075] The serial number request is a bandwidth allocation entry and an entry in the Upstream BWmap. Figure 5 shows the Upstream BWmap.

[0076] The serial number request is generally defined as follows: Alloc-ID = specified value (originally 254, now limited to uplink 1.25G rate SFU activation, and expanded to 255 and 253, see the table above), bit 10 in the Flags field, PLOAMu = '1', StartTime = X, and StopTime = X + 12, used to send an uplink PLOAM message with a length of 13 bytes.

[0077] In the example of the master gateway notifying its own capabilities through the PLOAM message, the original Extended_Burst_Length message is extended. The ss bit in the fifth byte is shown in Table 2 and is used to indicate the supported uplink rate.

[0078] Of course, it is also possible to extend other existing PLOAM messages or define new PLOAM messages, which will not be described in detail in this disclosure.

[0079] Table 2 Burst extension length information

[0080] Among them, the 1.24416Gbit / s uplink rate shown in Table 2 corresponds to the "1.25G" working mode (that is, the first working mode mentioned above), and the 2.48832Gbit / s uplink rate corresponds to the "2.5G" working mode (that is, the second working mode mentioned above).

[0081] The 1.25G uplink rate mentioned in this disclosure means the "1.25G" working mode, while the 2.5 uplink rate means the "2.5G" working mode.

[0082] GPON can perform activation periodically, for example, sending a serial number request every 10 seconds. As shown in Figure 6, the GPON activation process specifically includes:

[0083] Among them, the ONU in the GPON activation process can be understood as the above-mentioned slave gateway SFU, and the OLT in the GPON activation process can be understood as the above-mentioned master gateway MFU.

[0084] After an ONU entering the activation process monitors downstream transmissions and achieves PSync and superframe synchronization, it waits for an Upstream_Overhead PLOAM message, optionally followed by an Extended_Burst_Length PLOAM message periodically sent by the OLT. The ONU receives PON operating parameters (the length and pattern of the burst mode overhead component, the value of the pre-assigned delay, and the initial optical power level) via the Upstream_Overhead and Extended_Burst_Length messages. The ONU announces its presence on the PON by responding to the broadcast serial number requests periodically issued by the OLT using the Serial_Number_ONU message. The OLT discovers the serial number of the newly connected ONU and assigns it an ONU-ID using the Assign_ONU-ID message. The OLT issues a directed serial number request to the newly discovered ONU and accurately time-locates the ONU's response. The OLT calculates a separate equalization delay and sends it to the ONU using the Ranging_Time message. The ONU adjusts the start of its upstream GTC frame clock based on its assigned equalization delay. The ONU completes activation and begins normal operation.

[0085] Furthermore, other switching methods besides protocol-based switching can include configuring the uplink rate via software or external hardware. Specifically, one uplink rate can be configured first, activated, and then switched to a different uplink rate if activation fails. Of course, if software configuration is used, automatic retry of the software configuration method is also possible.

[0086] The communication method of the above-mentioned gateway device may include, for example, the following implementations:

[0087] Implementation method 1:

[0088] For the networking of 2.5G MFU (i.e. the first type of master gateway device mentioned above) and 2.5G SFU (i.e. the first type of slave gateway device mentioned above), the 2.5G MFU master gateway supports two uplink rates of 1.25G and 2.5G, and periodically starts the activation process, for example, once every 10 seconds. The Alloc-ID carried by the serial number request in each activation process changes alternately. One Alloc-ID = 255 allows SFU activation with a 2.5G uplink rate, and another Alloc-ID = 254 allows SFU activation with a 1.25G uplink rate.

[0089] If the 2.5G SFU hears the serial number request with Alloc-ID = 255, it ignores the serial number request with Alloc-ID = 254, chooses to work in symmetric 2.5G mode, responds to the serial number request and sends a Serial_Number_ONU message, and continues to complete the activation according to the GPON activation process.

[0090] Implementation 2:

[0091] For the networking of 2.5G MFU (i.e. the first type of master gateway device mentioned above) and 1.25G SFU (i.e. the second type of slave gateway device mentioned above), the 2.5G MFU master gateway supports two uplink rates of 1.25G and 2.5G, and periodically starts the activation process, for example, once every 10 seconds. The Alloc-ID carried by the serial number request in each activation process changes alternately. One Alloc-ID = 255 allows SFU activation with a 2.5G uplink rate, and another Alloc-ID = 254 allows SFU activation with a 1.25G uplink rate.

[0092] If the 1.25G SFU detects the serial number request of Alloc-ID=254 but does not support the serial number request of Alloc-ID=255, it responds to the serial number request of Alloc-ID=254 and sends a Serial_Number_ONU message, and continues to complete the activation according to the GPON activation process.

[0093] Implementation 3:

[0094] For the mixed networking of 2.5G MFU (i.e. the first type of master gateway device mentioned above) and 2.5G SFU and 1.25SFU (i.e. the third type of slave gateway device mentioned above), the 2.5G MFU master gateway supports two uplink rates of 1.25G and 2.5G, and periodically starts the activation process, for example, once every 10 seconds. The Alloc-ID carried by the serial number request in each activation process changes alternately. One Alloc-ID = 255 allows SFU activation with a 2.5G uplink rate, and another Alloc-ID = 254 allows SFU activation with a 1.25G uplink rate.

[0095] If the 1.25G SFU detects the serial number request of Alloc-ID=254 but does not support the serial number request of Alloc-ID=255, it responds to the serial number request of Alloc-ID=254 and sends a Serial_Number_ONU message, and continues to complete the activation according to the GPON activation process.

[0096] If the 2.5G SFU hears the serial number request with Alloc-ID = 255, it ignores the serial number request with Alloc-ID = 254, chooses to work in symmetric 2.5G mode, responds to the serial number request and sends a Serial_Number_ONU message, and continues to complete the activation according to the GPON activation process.

[0097] Implementation 4:

[0098] For the networking of 1.25G MFU (i.e. the second type of master gateway device mentioned above) and 1.25G SFU (i.e. the second type of slave gateway device mentioned above), the 1.25G MFU master gateway periodically starts the activation process and sends a serial number request with Alloc-ID=254 in standard mode.

[0099] If the 1.25G SFU detects the serial number request with Alloc-ID=254, it responds to the serial number request and sends a Serial_Number_ONU message, and continues to complete the activation according to the GPON activation process.

[0100] Implementation 5:

[0101] This embodiment is a protocol-based automatic switching mechanism.

[0102] For the networking of 1.25G MFU (i.e. the second type of master gateway device mentioned above) and 2.5G SFU (i.e. the first type of slave gateway device mentioned above), the 1.25G MFU master gateway periodically starts the activation process and sends a serial number request with Alloc-ID=254 in standard mode.

[0103] If the 2.5G SFU only hears the serial number request of Alloc-ID=254 from the gateway within a certain period of time (for example, within 1 minute) or a certain number of times (for example, within 10 times), but fails to hear the serial number request of Alloc-ID=255, it will reduce the speed to 1.25G mode, respond to the serial number request and send the Serial_Number_ONU message, and continue to complete the activation according to the GPON activation process.

[0104] Implementation 6:

[0105] This embodiment is an extension of the first embodiment.

[0106] For the networking of 2.5G MFU (i.e. the first type of master gateway device mentioned above) and 2.5G SFU (i.e. the first type of slave gateway device mentioned above), 2.5SFU can first work in 1.25 mode (it may be that when MFU broadcasts its capability, SFU does not detect the serial number request with Alloc-ID of 255), but during the activation process or after the activation is completed, it reports that it supports 2.5G mode. After the activation is completed, MFU configures SFU to work in 2.5G mode.

[0107] The 2.5G SFU can report its support for 2.5G mode during the activation process through the extended Serial_Number_ONU message. The extended Serial_Number_ONU message is shown in Table 3 below. When the A bit of the 12th byte is 1, it indicates that the SFU supports 2.5G mode.

[0108] Table 3 Serial number ONU information table

[0109] Among them, the 2.5G MFU configures the uplink rate of the SFU through the extended Assign_ONU-ID message. The SFU uses the corresponding uplink rate according to the configuration to send subsequent uplink messages and frames. The extended Assign_ONU-ID message is shown in Table 4 below. When the r bit of the 12th byte is 1, it indicates that the SFU is configured to work in the uplink rate mode of 2.5G.

[0110] Table 4 Assign_ONU-ID information table

[0111] Of course, after activation is completed, the SFU can report through other messages and the MFU can configure the uplink rate mode of the SFU through other messages, but the methods are similar and will not be repeated here.

[0112] Implementation 7:

[0113] This embodiment is expanded on the basis of the first embodiment.

[0114] For the networking of 2.5G MFU (i.e. the first type of master gateway device mentioned above) and 2.5G SFU (i.e. the first type of slave gateway device mentioned above), 2.5SFU can first work in 1.25 mode (it may be that when MFU broadcasts its capability, SFU does not detect the serial number request with Alloc-ID as 255). After the activation is completed, SFU detects the serial number request with Alloc-ID=255, then restarts the activation process, chooses to work in 2.5G mode and waits for listening to the serial number request with Alloc-ID=255, and completes the activation according to the GPON activation process.

[0115] Implementation 8:

[0116] For a mixed networking scenario of 1.25G MFU (i.e. the second type of master gateway device mentioned above) and 1.25G SFU and 2.5G SFU (i.e. the third type of slave gateway device mentioned above), the 1.25G MFU periodically sends a serial number request with Alloc-ID = 254.

[0117] If the 1.25G SFU hears the serial number request with Alloc-ID = 254, it responds to the serial number request and sends a Serial_Number_ONU message, and continues to complete the activation according to the GPON activation process;

[0118] If the 2.5G SFU only hears the serial number request of Alloc-ID=254 within a certain time (for example, within 1 minute) or a certain number of times (for example, within 10 times), and fails to hear the serial number request of Alloc-ID=255, it will reduce the speed to 1.25G mode, respond to the serial number request and send the Serial_Number_ONU message, and continue to complete the activation according to the GPON activation process.

[0119] Implementation 9:

[0120] In this embodiment, the serial number request can be replaced with a PLOAM message. Based on the above implementation, the master gateway MFU broadcasts its capabilities using an extended Extended_Burst_Length message. The master gateway SFU receives and parses the extended Extended_Burst_Length message to obtain the MFU's uplink rate capabilities and determine its own uplink rate. The traditional serial number request with Alloc-ID = 254 is still used, and activation is completed according to the activation process. This process is similar to the above implementation and will not be repeated here.

[0121] Implementation 10:

[0122] In this embodiment, the SFU can be configured to select an uplink rate mode through external configuration. Based on the above implementation, for a 2.5G SFU, an uplink rate mode can be selected at power-up. If the MFU supports the uplink rate, the 2.5G SFU completes activation according to the activation process. Otherwise, the uplink rate mode is switched through external configuration, such as software configuration, hardware switch control, etc., and the activation process is continued.

[0123] Implementation 11:

[0124] In this embodiment, the SFU can be configured to locally store the upstream rate mode. Based on the above implementation, after the SFU completes the activation process, it can store the SFU's current upstream rate mode. This stored information is not easily lost even if the SFU loses power. After the SFU is subsequently restarted, it reads the stored upstream rate mode and operates according to this mode, waiting for the corresponding serial number request or PLOAM message, and completing the activation according to the GPON activation process.

[0125] In this embodiment, a communication system for a gateway device is also provided. The system is configured to implement the above-mentioned embodiments and preferred implementations.
