Description

Technical Field

[0001] The present application 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

[0002] FTTR stands for Fiber to the room, and mainly adopts P2MP (point to multiplepoint) network architecture, such as Figure 1 As shown, the MFU (main FTTR unit, FTTR main gateway or master gateway) is connected to multiple SFUs (sub FTTR units, FTTR slave gateways or slave gateways) through the IFDN (Indoor Fibre Distribution Network).

[0003] China's three major operators are deploying FTTR on a large scale. As the standards have not yet been formally completed, Figure 2 In the PON (Passive Optical Network) network architecture shown in the figure, OLT (Optical Line Terminal) connects multiple ONUs (Optical Network Units) through ODN (Optical Distribution Network). The P2MP architecture of FTTR is similar to PON. Therefore, the currently deployed FTTR is mainly based on the industry's mature GPON (Gigabit Passive Optical Network) standard, using a downstream rate of 2.5G and an upstream rate of 1.25G.

[0004] Standards organizations such as CCSA (China Communications Standards Association) and ITU (International Telecommunications Union) are standardizing FTTR. Considering the needs of home interconnection, the symmetrical 2.5G rate is mainly used, and will be upgraded to a symmetrical 10G rate in the future. For the symmetrical 2.5G rate, it needs to be compatible with the existing deployed FTTR.

[0005] With regard to related technologies, there is no effective solution for how to achieve adaptive compatibility between symmetric 2.5G FTTR and existing asymmetric 2.5G FTTR.

[0039] The method embodiments provided in the embodiments of the present application can be executed in a computer terminal or a similar computing device. Taking running on a computer terminal as an example, Figure 3 1 is a hardware structure block diagram of a computer terminal of a communication method of a gateway device in an embodiment of the present application. Figure 3 As shown, the computer terminal may include one or more ( Figure 3 Only one is shown in the figure) processor 302 (processor 302 may include but is not limited to a microprocessor (Microprocessor Unit, referred to as MPU) or a programmable logic device (Programmable logic device, referred to as PLD)) and a memory 304 for storing data. In an exemplary embodiment, the computer terminal may also include a transmission device 306 and an input and output device 308 for communication functions. It can be understood by those skilled in the art that Figure 3 The structure shown is only for illustration and does not limit the structure of the above-mentioned computer terminal. Figure 3 More or fewer components as shown, or with Figure 3 Equivalent functions or comparisons shown Figure 3 A different configuration with more features is shown.

[0040] The memory 304 can be used to store computer programs, for example, software programs and modules of application software, such as the computer program corresponding to the communication method of the gateway device in the embodiment of the present application. The processor 302 executes various functional applications and data processing by running the computer program stored in the memory 304, that is, to implement the above method. The memory 304 may include a high-speed random access memory, and may also include a non-volatile memory, such as one or more magnetic storage devices, flash memory, or other non-volatile solid-state memory.

[0042] Figure 4 is a flow chart of a communication method of a gateway device according to an embodiment of the present application, such as Figure 4 As shown, the steps of the method include:

[0043] Step S402, determining a target working 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;

[0044] Step S404: the slave gateway device communicates with the master gateway device according to the target working mode.

[0045] The embodiment of the present application determines the 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; 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.

[0046] Among them, the master gateway device can be referred to as the master gateway, and the slave gateway device can be referred to as the slave gateway.

[0047] 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.

[0048] Optionally, the master gateway may send its own capabilities through a serial number request. For the indication of the uplink rate, it may also be set and sent through a PLOAM broadcast, such as in an extended Upstream_Overhead message. The slave gateway may check the values ​​of the relevant fields to determine the capabilities of the master gateway.

[0049] Optionally, when the Alloc-ID of the serial number request is 254, it indicates that the MFU supports an uplink rate of 1.25G.

[0050] Among them, Alloc-ID (Allocation Identifier) ​​is a unique identifier used in the GPON (Gigabit Passive Optical Network) standard to identify the transmission container allocated to the ONU (Optical Network Unit). The OLT allocates bandwidth to the transmission container so that the ONU obtains an upstream transmission opportunity.

[0051] The value range of Alloc-ID is 0-4095, of which 0-252 is the default allocation value, which is consistent with the ONU identification, 253, 254 and 255 are reserved broadcast values ​​for ONU activation, and other values ​​are used to allocate to different ONU transmission containers.

[0052] Among them, the role of Alloc-ID is to distinguish different ONU devices and their corresponding transmission containers in the GPON network.

[0053] Among them, when the Alloc-ID of the serial number request is 254, it means that the MFU supports 1.25G upstream rate, which is specified in the existing GPON standard;

[0054] Optional. When the Alloc-ID of the serial number request is 255, it indicates that the MFU supports 2.5G uplink rate.

[0055] Optionally, when the Alloc-ID of the serial number request is 253, it indicates that the MFU supports 1.25G uplink rate and 2.5G uplink rate.

[0056] Optionally, the 2.5G FTTR main gateway can send serial number request with Alloc-ID of 255 and 254 alternately, or send serial number request with Alloc-ID of 253 alone, indicating that it supports uplink 1.25G rate and 2.5G rate. The following embodiments take the serial number request with Alloc-ID of 255 and 254 alternately as an example. This embodiment can also be modified to send serial number request with Alloc-ID of 253 alone, and the process is similar. The 2.5G FTTR main gateway can also send serial number request with Alloc-ID of 255 or 254 alone, indicating that it only supports 2.5G uplink rate or 1.25G uplink rate.

[0057] Optionally, the 1.25G FTTR main gateway generally sends a serial number request with Alloc-ID 254.

[0058] Optionally, the master gateway may also send its own capabilities by filling in corresponding values ​​in relevant fields through PLOAM messages or other methods, as detailed in the implementation method.

[0059] 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.

[0060] For example, the FTTR slave gateway obtains the capability of the FTTR master gateway by obtaining the Alloc-ID carried in the serial number request sent by the FTTR master gateway, and determines its own working mode.

[0061] Optionally, for a 2.5G FTTR slave gateway, if it can receive a serial number request with Alloc-ID of 255 or 253, it works in 2.5G mode; if it can only receive a serial number request with Alloc-ID of 254, it will reduce the speed and work in 1.25G mode.

[0062] Optionally, for a 1.25G FTTR slave gateway, if it can receive a serial number request with Alloc-ID 254 or 253, it will respond in 1.25G mode and will not respond to a serial number request with Alloc-ID 255.

[0063] 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, as described in detail in the implementation method.

[0064] 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.

[0065] In an exemplary embodiment, before executing the above step S402, a message field may 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.

[0066] 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.

[0067] 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 operates in the first working mode, the first uplink rate corresponding to the first working mode is determined as the target uplink rate, and the channel identifier carried by the message field is set to the first identifier used to represent the uplink rate of the first working mode; when it is determined that the master gateway device operates in the second working mode, the second uplink rate corresponding to the second working mode is determined as the target uplink rate, and the channel identifier carried by the message field is set to the second identifier used to represent the uplink rate of the second working mode; when it is determined that the master gateway device operates in the first working mode and the second working mode, the first uplink rate corresponding to the first working mode and the second uplink rate corresponding to the second working mode are determined as the target uplink rate, and the channel identifier carried by the message field is set to the third identifier used to represent the uplink rates of the first working mode and the second working mode; wherein the second uplink rate is greater than the first uplink rate.

[0068] In an exemplary embodiment, for an implementation process of determining a target operating mode of a slave gateway device based on an uplink rate supported by a master gateway device and an uplink rate supported by a slave gateway device, the specific steps include: obtaining all operating modes supported by the slave gateway device; wherein each of all operating modes corresponds to an uplink rate; and determining a target operating mode that supports the target uplink rate from among all operating modes.

[0069] Optionally, the intersection of all working modes supported by the slave gateway device and all working modes supported by the master gateway device may be taken to obtain a working mode set, and the optimal working mode may be selected from the working mode set as the target working mode. For example, the working mode with the largest uplink rate in the working mode set may be determined as the target working mode to increase the uplink transmission capacity and reduce the uplink transmission delay, or the working mode with the smallest uplink rate in the working mode set may be determined as the target working mode to reduce the energy consumption required for uplink transmission, etc. If there is only one working mode in the working mode set, this working mode is determined as the target working mode.

[0070] In an exemplary embodiment, a plurality of technical solutions are proposed for determining a target operating mode supporting the target uplink rate from all the operating modes, including:

[0079] 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.

[0080] This embodiment also includes Scheme 9, in the case where the channel identifier is carried by the PLOAM field, determining the extended burst length information from the PLOAM field; determining the target uplink rate indicated by the channel identifier carried by the message field, and determining the target working mode of the slave gateway device that supports the target uplink rate, wherein the determining the target uplink rate indicated by the channel identifier carried by the message field and determining the target working 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 working mode of the slave gateway device that supports the target uplink rate.

[0083] 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.

[0084] Next, the communication method of the gateway device is further described in conjunction with the following embodiments.

[0085] The following is the real-time preparation work of the communication method of the gateway device in this application:

[0086] At present, the FTTR standards of CCSA and ITU-T are mainly modified and improved on the basis of GPON and XGS-PON (10-Gigabit-capable symmetric passive optical network, symmetric 10G passive optical network) standards. The following expansion is based on GPON as an example.

[0087] The result of modifying the Alloc-ID of the GPON standard is shown in Table 1 below. The modification mainly extends the Alloc-ID of the serial number request.

[0088] Table 1 Alloc-ID information table

[0089]

[0090]

[0091] The serial number request is a bandwidth allocation entry and is an entry in the Upstream BWmap. Figure 5 shown.

[0092] The serial number request is generally defined as: Alloc-ID = specified value (the original value is 254, which is now limited to the upstream 1.25G rate SFU activation, and extended to two values ​​255 and 253, see the description in the table above), bit 10 in the Flags field, PLOAMu = '1', StartTime = X, and StopTime = X+12, used to send an upstream PLOAM message with a length of 13 bytes.

[0093] In the example of the master gateway notifying its own capabilities through the PLOAM message, the original Extended_Burst_Length message is extended, and the ss bit in the 5th byte is shown in Table 2, which is used to indicate the supported uplink rate.

[0094] 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 application.

[0095] Table 2 Burst extension length information

[0096]

[0097]

[0098] Among them, the 1.24416Gbit / s uplink rate shown in Table 2 corresponds to the "1.25G" working mode (ie, the first working mode mentioned above), and the 2.48832Gbit / s uplink rate corresponds to the "2.5G" working mode (ie, the second working mode mentioned above).

[0099] The 1.25G uplink rate mentioned in this application means the "1.25G" working mode, while the 2.5 uplink rate means the "2.5G" working mode.

[0100] GPON can perform activation process periodically, for example, sending a serial number request every 10 seconds. Figure 6 As shown in the figure, the GPON activation process specifically includes:

[0101] 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.

[0102] After the ONU entering the activation process listens to the downstream transmission and obtains PSync and superframe synchronization: the ONU waits for the Upstream_Overhead PLOAM message, optionally followed by the Extended_Burst_Length PLOAM message periodically issued by the OLT. The ONU receives the PON operating parameters (the length and mode of the burst mode overhead component, the value of the pre-assigned delay, and the initial optical power level) through the Upstream_Overhead and Extended_Burst_Length messages. The ONU announces its presence on the PON by responding to the broadcast serial number request regularly issued by the OLT using the Serial_Number_ONU message. The OLT discovers the serial number of the newly connected ONU and assigns the ONU-ID to it using the Assign_ONU-ID message. The OLT issues a directional 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 the equalization delay 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.

[0103] Furthermore, for other switching methods other than those based on protocols, the uplink rate can be configured by software or by external hardware. That is, one uplink rate can be configured first, and activation can be attempted. If activation cannot be completed, another uplink rate can be switched. Of course, if the software configuration method is used, the software configuration method can also be automatically attempted.

[0104] The communication method of the above-mentioned gateway device may include, for example, the following implementations:

[0105] Implementation 1:

[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), 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 an uplink rate of 2.5G, and another Alloc-ID = 254 allows SFU activation with an uplink rate of 1.25G.

[0107] If the 2.5G SFU detects the serial number request of Alloc-ID=255, it ignores the serial number request of Alloc-ID=254, chooses to work in the symmetric 2.5G mode, responds to the serial number request and sends the Serial_Number_ONU message, and continues to complete the activation according to the GPON activation process.

[0108] Implementation 2:

[0109] 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 an uplink rate of 2.5G, and another Alloc-ID = 254 allows SFU activation with an uplink rate of 1.25G.

[0110] 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.

[0111] Implementation 3:

[0112] For the mixed networking of 2.5G MFU (i.e. the first type of master gateway device mentioned above) and 2.5G SFU, 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 an uplink rate of 2.5G, and another Alloc-ID = 254 allows SFU activation with an uplink rate of 1.25G.

[0113] 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.

[0114] If the 2.5G SFU detects the serial number request of Alloc-ID=255, it ignores the serial number request of Alloc-ID=254, chooses to work in the symmetric 2.5G mode, responds to the serial number request and sends the Serial_Number_ONU message, and continues to complete the activation according to the GPON activation process.

[0115] Implementation 4:

[0116] For the networking of 1.25G MFU (ie the second type of master gateway device) and 1.25G SFU (ie the second type of slave gateway device), the 1.25G MFU master gateway periodically starts the activation process and sends a serial number request with Alloc-ID=254 in standard mode.

[0117] If the 1.25G SFU detects the serial number request of 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] Implementation 5:

[0119] This implementation is an automatic switching mechanism based on a protocol.

[0120] For the networking of 1.25G MFU (ie the second type of master gateway device) and 2.5G SFU (ie the first type of slave gateway device), the 1.25G MFU master gateway periodically starts the activation process and sends a serial number request with Alloc-ID=254 in standard mode.

[0121] 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.

[0122] Implementation 6:

[0123] This embodiment is an extension of the first embodiment.

[0124] 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.

[0125] The 2.5G SFU can report that it supports the 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, where when the A bit of the 12th byte is 1, it indicates that the SFU supports the 2.5G mode.

[0126] Table 3 Serial number ONU information table

[0127]

[0128]

[0129] 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 to send subsequent uplink messages and frames according to the configuration. The extended Assign_ONU-ID message is shown in Table 4 below, where the r bit of the 12th byte is 1, indicating that the SFU is configured to work in the uplink rate mode of 2.5G.

[0130] Table 4 Assign_ONU-ID information table

[0131]

[0132] Of course, after the 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 one by one.

[0133] Implementation 7:

[0134] This implementation is expanded on the basis of the first implementation.

[0135] 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 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.

[0136] Implementation 8:

[0137] For the mixed networking 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), 1.25G MFU periodically sends a serial number request with Alloc-ID=254;

[0138] 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;

[0139] If the 2.5G SFU only hears the serial number request of Alloc-ID=254 within a certain period of 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.

[0140] Implementation 9:

[0141] In this embodiment, the serial number request can be replaced with a PLOAM message. Based on the above implementation, the main gateway MFU broadcasts its own capabilities with an extended Extended_Burst_Length message, receives and parses the extended Extended_Burst_Length message from the gateway SFU to obtain the uplink rate capability of the MFU, and determines its own uplink rate, still using the traditional Alloc-ID = 254 serial number request, and completing the activation according to the activation process. The process is similar to the above implementation, and will not be repeated here.

[0142] Implementation 10:

[0143] In this embodiment, the SFU can be set to select the uplink rate mode through external configuration. Based on the above implementation, for 2.5G SFU, an uplink rate mode can be selected when powered on. If the MFU supports its uplink rate, the 2.5G SFU completes the 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.

[0144] Implementation 11:

[0145] In this embodiment, the SFU can be set to store the upstream rate mode locally. Based on the above implementation, after the SFU completes the activation process, the current upstream rate mode of the SFU can be stored, and this storage information is not easily lost even if the SFU is powered off. After the SFU is restarted, the stored upstream rate mode is read and operated according to the mode, waiting for the corresponding serial number request or PLOAM message, and completing the activation according to the GPON activation process.

[0146] In this embodiment, a communication system of a gateway device is also provided, which is used to implement the above-mentioned embodiments and preferred implementation modes, and the descriptions that have been made will not be repeated. As used below, the term "module" can implement a combination of software and / or hardware for a predetermined function. Although the devices described in the following embodiments are preferably implemented in software, the implementation of hardware, or a combination of software and hardware, is also possible and conceivable.
