Abstract

The embodiment of the invention provides a paging method and device based on a narrowband Internet of Things, wherein the narrowband Internet of Things comprises a core network, a base station and UE.The method includes: the base station receives paging auxiliary information sent from the core network; the base station determines the actual repetition times of paging a narrowband physical downlink control channel NPDCCH according to the paging auxiliary information; the base station obtains a Paging record; the Paging record is sorted; the base station queries the Paging record number of themaximum number of users that can be carried in a paging message according to the actual repetition times of paging the NPDCCH; the base station extracts the sorted Paging record of the corresponding number of users according to the Paging record number of the maximum number of users; the base station composes the extracted Paging record into a paging message packet; and the paging message packet is sent to the UE. The paging method and device improve the paging efficiency, make the paging faster and more efficient, and can effectively improve the paging success rate of the narrowband Internetof Things.

Description

technical field [0001] The present invention relates to the technical field of communication, in particular to a method based on NB-IoT and a device based on NB-IoT. Background technique [0002] Compared with the LTE network, the NB-IoT has enhanced each channel in the NB-IoT, that is, the introduction of Enhanced Coverage (enhanced coverage), but after the introduction of this technology, in the paging (paging) operation of the NB-IoT UE (User Equipment, user equipment) needs to undergo multiple repeated transmissions to undergo correct demodulation through combined decoding; at the same time, in order to save bandwidth resources, the system bandwidth of NB-IoT is smaller than that of LTE network, and the conventionally available RB ( resource block, resource block) resources are also significantly reduced; referring to Table 1, it shows the bandwidth and resource comparison of the LTE network of the present technology and the narrowband Internet of Things; wherein, the na...
