Fig. 2 is a schematic diagram of an on-line flow of an HINOC terminal in a specific application scenario in an embodiment of the present application.
In the online method provided by the application, HB local side equipment supports N HINOC channels, and certain HM terminal equipment supports M channel bonding. The HINOC terminal on-line process shown in FIG. 2 is specifically described as follows:
step a1: HB synchronously transmits a downlink EMPTY frame on each HINOC channel with 64ms as a period and carries network capability description (wherein the information influencing the online flow comprises frequency points of each channel, the number of online nodes and load on each channel);
step a2: the NHM tries to synchronize the downlink EMPTY frame on the preset M frequency points, if the NHM cannot synchronize to the downlink EMPTY frame on all preset channels, the NHM enters a frequency sweeping process until at least one channel synchronizes to the downlink EMPTY frame;
Step a3: as long as synchronizing to the downlink EMPTY frame on any channel, the NHM can acquire the key information of the whole network from the frame and rapidly synchronize to the remaining M-1 channels;
step a4: 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 equipment ID (such as 0 xFF);
step a5: HB receives the admission request of NHM on a certain channel, allocates equipment ID for NHM, allocates channel ID on the channel for NHM, and sends admission response frame form to NHM on the channel;
step a6: the NHM receives the admission response frame, reads the obtained device ID from the admission response frame, carries the device ID on the rest channels synchronized to the downlink EMPTY frame, and independently initiates an admission request in parallel;
step a7: HB receives the online request with equipment ID, allocates corresponding channel ID for NHM according to its strategy, and informs NHM by admission response frame; if NHM does not allow online on some channels, HB definitely gives refusal in the admission response frame, NHM can switch to other channels to try online;
step a8: the NHM may perform power adjustment on the channel to which the channel ID is allocated, and perform uplink and downlink channel training by interacting with the HB with the downlink and uplink frames. HB and NHM independently count the number of the received uplink EMPTY and downlink EMPTY frames respectively, and determine whether the uplink and downlink channel training is completed. Under the optimal condition, the training processes of the uplink channel and the downlink channel are overlapped in time, so that the online time of the NHM is greatly reduced. Even in the worst case, can be consistent with the prior art;
Step a9: after channel training in either direction is completed, the device can perform modulation format calculation and then notify the device by "uplink modulation format report" or "downlink modulation format report". The calculation and the release of the uplink/downlink channel modulation formats are mutually independent;
step a10: the HB updates the modulation format of the multicast, broadcast and profile of the channel and publishes to the whole network.
Step a11: when the M channels all complete 6-10 steps, the HM is successfully connected. If the number of channels that a device can access is less than M due to resource issues or policy constraints, the HM comes online with partial capability. 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 an embodiment of the present application.
In the online method provided by the embodiment of the disclosure, in order to prevent two MAC addresses from being online at the same time when the same HM is used. The online method provided by the embodiment of the disclosure provides the following processing steps:
step b1: HB synchronously transmits a downlink EMPTY frame on each HINOC channel with 64ms as a period and carries network capability description (wherein the information influencing the online flow comprises frequency points of each channel, the number of online nodes and load on each channel);
Step b2: due to network deployment problems, the network has two NHMs with the same MAC address and is powered on at the same time;
step b3: the two NHMs simultaneously receive the downlink EMPTY frame on the channels that each allows to operate, and each selects an available channel to initiate an admission request according to the constraint in 5.1. Since neither NHM obtains the device ID at this time, both initiate an admission request with a special value as the device ID;
step b4: HB receives admission requests with special values of two device IDs from the same MAC address on two channels at the same time, and selects one to give acknowledgement permission to the online request, and refuses the online request of the other terminal (refusing the reason is the conflict of the MAC address); in this step, the process of determining the license from the two devices is random, and after one is determined to be a licensed device, the other is a device to which the license is denied.
Step b5: the terminal that receives the on-line request permission may perform the same steps as the following steps shown in fig. 2. The details are not repeated, and please refer to the description of the specific steps as described in fig. 2.
After screening out the channels to be online, the embodiment of the disclosure introduces the HM terminal which has multi-channel performance and can work on all the M HINOC channels, marks 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 after the sweep frequency and channel selection processing, so as to control the HM terminal to complete the processing procedures of responding to the admission request, configuring the corresponding channel power control parameters, uplink channel training, updating and publishing the modulation format information on each HINOC channel which is less than or equal to M-1 until the HM terminal is partially or completely online.
In the embodiment of the application, any device is randomly selected from the HB local side and any candidate HM terminal to be used as the device for screening the channel to be on line; according to a local side channel screening model corresponding to the 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 be used as preferential selection channels of any HM terminal on line meeting the condition, wherein any HM terminal meeting the condition can work on any HINOC channel in the M HINOC channels, M is a positive integer smaller than or equal to N, and N is a positive integer larger than 1. The scheme provided by the application not only can screen the channel which meets the condition and can be on line from the HB local side, but also can screen the channel which meets the condition and can be on line from any candidate HM terminal, thereby realizing the diversity of the screening main body.
