As shown in fig. 1, a pluggable communication module can be installed at the convergence device corresponding to the convergence of the convergence device at the convergence point 1, and wireless communication connection between the narrowband terminal device and the convergence device is realized through the communication module.

And a step a4, the unaccessed node sends a network access request through a random access time slot.
And a5, after receiving the network access request, the preset node checks the identity of the non-access node, if the identity passes, the preset node allocates an uplink time slot for the non-access node and sends a successful network access confirmation to the non-access node.
And a step a6, when the non-access node receives the successful acknowledgement of network access, namely the successful network access, the configuration is carried out according to the time slot allocation in the acknowledgement information, and the power width fusion wireless sensor network is generated.

(4) The non-access device sends a network access request through a random access time slot.
(5) And after receiving the network access request, the side equipment checks the identity of the non-access equipment, if the identity passes, the side equipment allocates an uplink time slot for the non-access equipment and sends a successful network access confirmation to the non-access equipment, otherwise, the side equipment sends a failed network access confirmation to the non-access equipment.
(6) When the side equipment allocates uplink time slots for the unaccessed equipment, the requirements of bandwidth, time delay and the like of the unaccessed equipment for carrying the service are comprehensively considered. If the unaccessed equipment is broadband terminal equipment, the bandwidth requirement of the unaccessed equipment needs to be considered when the time slot allocation is carried out; if the unaccessed equipment is the narrowband terminal equipment, the communication success rate requirement of the unaccessed equipment needs to be considered when the time slot allocation is carried out.
(7) And after receiving the successful acknowledgement of network access, the non-access equipment is successful in network access. And configuring according to the time slot allocation in the confirmation information.
In the data transmission stage, the aggregation device and the terminal device only perform data transmission in the uplink time slot allocated to the aggregation device and the terminal device, and when the upper network performs fusion, an example of time slot resource allocation is shown in fig. 5.
