Among them, M is a positive integer less than or equal to N, and N is a positive integer greater than 1.

Specifically, the process of controlling the HM terminal to complete responding to an admission request, configuring corresponding channel power control parameters, uplink channel training, and updating and publishing modulation format information on any channel of M's HINOC channel for the first time includes the following steps: :

In response to the first admission request of the HM terminal, configure the corresponding device ID and channel ID for the HM terminal, and send the first admission response frame to the HM terminal on the channel ID, and the admission response frame carries the device of the HM terminal ID information and the first channel ID information of the HM terminal;

In response to the second admission request of the HM terminal, configure the corresponding second channel ID for the HM terminal, and send the second admission response frame corresponding to the second admission request to the HM terminal, the second admission response frame carrying the second channel ID information and channel power control parameter information of the HM terminal on the second channel;

Perform uplink channel training on the uplink channel by interacting with the HM terminal with the first type of uplink EMPTY frame, and at the end of the uplink channel training, update and release the modulation format information based on the obtained first updated modulation format information; wherein, the first The modulation format information includes at least one of the following: uplink format modulation information, HINOC channel broadcast modulation format information, HINOC channel multicast modulation format information, and Profile modulation format information.

Figure 2 is a schematic diagram of the HINOC terminal online process in a specific application scenario in the embodiment of this application.

In the online method provided by this application, the HB central office equipment supports N HINOC channels, and a certain HM terminal equipment supports M channel binding. The HINOC terminal online process shown in Figure 2 is as follows:

Step a1: HB synchronously sends downlink EMPTY frames on each HINOC channel with a cycle of 64ms, and carries a network capability description (the information that affects the online process includes the frequency of each channel, the number of online nodes on each channel, and the load);

Step a2: NHM attempts to synchronize the downlink EMPTY frame on the preset M frequency points. If the downlink EMPTY frame cannot be synchronized on all preset channels, it will enter the frequency scanning process until it is synchronized on at least one channel. Until the downlink EMPTY frame;

Step a3: As long as the downlink EMPTY frame is synchronized on any channel, NHM can obtain the key information of the entire network and quickly synchronize to the remaining M-1 channels;

Step a4: NHM uses a specific strategy to select a channel (such as the channel with the lowest channel load) to initiate an admission request. The admission request carries the MAC address of the terminal and a special device ID (such as 0xFF);

Step a5: HB receives the admission request from the NHM on a certain channel, allocates a device ID to the NHM, allocates a channel ID on the channel to the NHM, and sends it to the NHM in the form of an admission response frame on the channel;

Step a6: NHM receives the admission response frame, reads the obtained device ID from it, and then carries the device ID on the remaining channels that have been synchronized to the downlink EMPTY frame, and initiates an admission request independently and in parallel;

Step a7: HB receives the online request with the device ID, assigns the corresponding channel ID to the NHM according to its policy, and notifies the NHM through the admission response frame; if the NHM is not allowed to go online on certain channels, the HB explicitly admits If rejected in the response frame, NHM can switch to another channel to try to go online;

Step a8: NHM can perform power adjustment on the channel assigned a channel ID, and perform uplink and downlink channel training by exchanging downlink EMPTY frames and uplink EMPTY frames with the HB. HB and NHM independently count the number of received uplink EMPTY and downlink EMPTY frames to determine whether the uplink and downlink channel training is completed. Under optimal circumstances, the training processes of the uplink channel and the downlink channel overlap in time, which greatly reduces the time for NHM to go online. Even in the worst case scenario, it can remain consistent with existing technology;

Step a9: After the channel training in either direction is completed, the device can calculate the modulation format, and then notify via "Uplink Modulation Format Report" or "Downlink Modulation Format Report". The calculation and release of uplink/downlink channel modulation formats are independent of each other;

Step a10: HB updates the multicast, broadcast and profile modulation formats of the channel and publishes them to the entire network.

Step a11: When all M channels have completed steps 6 to 10, the HM is successfully online. If the number of channels that a device can access is less than M due to resource issues or policy constraints, the HM goes online with partial capabilities. Figure 3 is a schematic diagram of the online process of two HINOC terminals with the same MAC address in another specific application scenario in the embodiment of the present application.

In the online method provided by the embodiment of the present disclosure, in order to prevent two HMs with the same MAC address from going online at the same time. The online method provided by the embodiment of the present disclosure provides the following processing steps:

Step b1: HB synchronously sends downlink EMPTY frames on each HINOC channel with a cycle of 64ms, and carries a network capability description (the information that affects the online process includes the frequency of each channel, the number of online nodes on each channel, and the load);

Step b2: Due to network deployment issues, there are two NHMs with the same MAC address on the network, and they are powered on at the same time;

Step b3: The two NHMs receive the downlink EMPTY frame at the same time on the channels they are allowed to operate. According to the constraints in 5.1, each NHM selects an available channel to initiate an admission request. Since neither NHM has obtained the device ID at this time, they both use a special value as the device ID to initiate an admission request;

Step b4: HB receives admission requests from two device IDs with special values from the same MAC address on two channels at the same time, selects one of them to grant the online request confirmation permission, and rejects the online request of the other terminal (rejection reason) (for MAC address conflicts); in this step, the process of determining permissions from two devices is random. After one is determined to be a permitted device, the other one is a device that is denied permission.

Step b5: The terminal that receives the online request permission can follow the same subsequent steps as shown in Figure 2. The details will not be described again. Please refer to the description of the specific steps as shown in Figure 2.

After screening out the channels to be brought online, the embodiment of the present disclosure introduces an HM terminal with multi-channel performance and capable of working on M HINOC channels. After frequency scanning and channel selection processing, the first successful The device ID of the accessed HM terminal device and the channel ID of the first access are marked so that the HM terminal can be controlled to complete the response to the admission request and configure the corresponding channel power on each HINOC channel less than or equal to M-1. The process of updating and releasing control parameters, uplink channel training, and modulation format information until some or all of the HM terminals come online.

In the embodiment of this application, any device is randomly selected from the HB central office and any candidate HM terminal as the device for screening channels to be online; according to the central office channel screening model corresponding to the HB central office or the terminal corresponding to any candidate HM terminal The channel screening model selects M HINOC channels from the N HINOC channels supported by the HB central office as the priority channel for any HM terminal that meets the conditions to go online. Among them, any HM terminal that meets the conditions can be selected among the M HINOC channels. It works on any HINOC channel, M is a positive integer less than or equal to N, and N is a positive integer greater than 1.
