Fig. 2 is a schematic diagram of an online flow of a HINOC terminal in a specific application scenario in the embodiment of the present application.
In the online method provided by the application, the HB local side device supports N HINOC channels, and a certain HM terminal device supports M channel bonding. The HINOC terminal online process shown in fig. 2 is specifically described as follows:
step a 1: the HB synchronously sends downlink EMPTY frames on each HINOC channel in a cycle of 64ms and carries network capability description (wherein information influencing an online flow comprises frequency points of each channel, online node number and load on each channel);
step a 2: the NHM tries to synchronize the downlink EMPTY frame on the preset M frequency points, if the downlink EMPTY frame cannot be synchronized on all the preset channels, the frequency sweeping process is started until the downlink EMPTY frame is synchronized on at least one channel;
step a 3: as long as the downlink EMPTY frame is synchronized on any channel, the NHM can acquire the key information of the whole network from the downlink EMPTY frame and quickly synchronize to the remaining M-1 channels;
step a 4: the NHM selects a channel (such as the channel with the lowest channel load) to initiate an admission request according to a specific strategy, wherein the admission request carries the MAC address of the terminal and a special device ID (such as 0 xFF);
step a 5: the HB receives the admission request of NHM on a certain channel, distributes equipment ID for the NHM, distributes channel ID on the channel for the NHM, and sends the channel ID to the NHM in the form of admission response frame on the channel;
step a 6: the NHM receives the admission response frame, reads the obtained equipment ID from the admission response frame, carries the equipment ID on the residual channels synchronized to the downlink EMPTY frame immediately, and independently and parallelly initiates an admission request;
step a 7: HB receives the request of going online with equipment ID, according to its tactics, assigns corresponding channel ID for NHM, and notify NHM through admitting the response frame; if the NHM does not allow to go online on some channels, the HB explicitly gives rejection in the admission response frame, and the NHM can switch to other channels to try to go online;
step a 8: the NHM may perform power adjustment on a channel to which a channel ID is allocated, and perform uplink and downlink channel training by interacting with the HB with a downlink EMPTY frame and an uplink EMPTY frame. HB and NHM separately counts the number of up run EMPTY and down run EMPTY frame received, decides whether the up run channel training is finished. Under the optimal condition, the training processes of the uplink channel and the downlink channel are overlapped in time, so that the time for the NHM to be on-line is greatly reduced. Even in the worst case, the method can be kept consistent with the prior art;
step a 9: after the channel training in any direction is finished, the device may calculate the modulation format, and then notify the device through an uplink modulation format report or a downlink modulation format report. The calculation and the release of the modulation formats of the uplink/downlink channels are independent;
step a 10: and the HB updates the multicast and broadcast of the channel and the modulation format of the profile and distributes the channel to the whole network.
Step a 11: when the M channels finish 6-10 steps, the HM is successfully on line. If the number of channels that a device can access is less than M due to resource issues or policy constraints, the HM comes on-line with some of the capabilities. Fig. 3 is a schematic diagram of an online flow of two HINOC terminals having the same MAC address in another specific application scenario in this embodiment of the present application.
In the online method provided by the embodiment of the disclosure, in order to prevent two HMs with the same MAC address from being online at the same time. The online method provided by the embodiment of the disclosure provides the following processing steps:
step b 1: the HB synchronously sends downlink EMPTY frames on each HINOC channel in a cycle of 64ms and carries network capability description (wherein information influencing an online flow comprises frequency points of each channel, online node number and load on each channel);
step b 2: due to the network deployment problem, two NHMs with the same MAC address exist in the network, and the network is powered on at the same time;
step b 3: two NHMs receive the downlink EMPTY frame on the respective allowed channels at the same time, and each select an available channel to initiate an admission request according to the constraint in 5.1. At this time, because neither NHM obtains the device ID, both NHMs initiate an admission request with the special value as the device ID;
step b 4: the HB receives admission requests with two equipment IDs which are both special values from the same MAC address on two channels simultaneously, selects one of the admission requests to give an on-line request confirmation permission, and rejects the on-line request of the other terminal (the rejection reason is MAC address conflict); in this step, the process of determining permission from two devices is random, and after determining one as a permitted device, the other is a device for which permission is denied.
Step b 5: the terminal receiving the online request permission performs the following same steps as shown in fig. 2. For details, please refer to the description of the specific steps shown in fig. 2.
After channels to be brought online are screened out, the HM terminal which has multi-channel performance and can work on M HINOC channels is introduced in the embodiment of the disclosure, and after frequency sweep and channel selection processing, the device ID of the HM terminal device which is successfully accessed for the first time and the channel ID which is accessed for the first time are marked, so that the HM terminal is controlled to complete the processing processes of responding to an admission request, configuring corresponding channel power control parameters, uplink channel training, updating and issuing of modulation format information on each HINOC channel which is less than or equal to M-1 until the HM terminal part or all the channels are brought online.
In the embodiment of the application, any device is randomly selected from an HB local side and any candidate HM terminal as a device for screening a channel to be on-line; according to a local side channel screening model corresponding to an HB local side or a terminal channel screening model corresponding to any candidate HM terminal, M HINOC channels are screened from N HINOC channels supported by the HB local side to serve as priority selection channels on-line of any HM terminal meeting the conditions, wherein any HM terminal meeting the conditions can work on any HINOC channel of the M HINOC channels, M is a positive integer smaller than or equal to N, and N is a positive integer larger than 1. Due to the scheme provided by the application, not only can channels which are on-line by the HM terminal meeting the conditions be screened from the HB local side, but also channels which are on-line by the HM terminal meeting the conditions can be screened from any candidate HM terminal, so that the diversity of screening main bodies is realized.
