Paging method and base station

Abstract

The embodiment of the invention provides a paging method and a base station. The method comprises the steps that whether the paging resource is occupied is detected according to the received paging message; if the paging resource is occupied, the paging resource is preoccupied and the paging message is sent by using the paging resource, wherein the timer is started at the moment when resource occupation of the paging message is successful; and the continuous transmission strategy corresponding to the transmission service is determined according to the type of the transmission service previously occupying the paging resource at the moment of the timing end of the timer. Therefore, the system resource utilization rate and performance can be effectively enhanced and the success rate of pagingcan be significantly enhanced.

Description

technical field [0001] The embodiments of the present invention relate to the communication field, and in particular to a paging method and a base station. Background technique [0002] In the NB-IoT (Narrowband Internet of Things, cellular-based narrowband Internet of Things) system, narrowband physical downlink control channel (Narrowband Physical Downlink Control Channel, NPDCCH) channel and narrowband physical downlink shared channel (Narrowband Physical Downlink Shared Channel, NPDSCH) The transmission of the channel needs to occupy the entire narrowband, and a large number of repeated transmissions are used to obtain receiving gain for terminals at a high coverage level, so as to improve the coverage capability. [0003] The paging message is sent according to the paging frame (PagingFrame, PF) and paging occasion (PagingOccasion, PO) of the paging cycle, and the paging of multiple terminals at the same paging occasion will be sent together (up to 16 terminal Due to t...

Problems solved by technology

[0003] The paging message is sent according to the paging frame (PagingFrame, PF) and paging occasion (PagingOccasion, PO) of the paging cycle, and the paging of multiple terminals at the same paging occasion will be sent together (up to 16 terminal Paging messages sent together), due to the large number of repetitions of the NPDCCH and NPDSCH of other online terminal services, the downlink resources corresponding to the paging occasions are often occupied, resulting in the failure of paging transmission

[0004] In addition, the base station will package the paging message to form a paging packet. Since the coverage levels of the terminals are not the same, in order to allow the terminal at a high coverage level to successfully receive the paging message, the packaged paging message The paging will be sent with the number of repetitions corresponding to the terminal with the highest coverage level in the packet, that is, under normal circumstances, paging message transmission requires a large number of repetitions and more continuous downlink resources, which further increases the probability of paging resource allocation failure. possible

After the paging fails, the core network will expand the paging range and paging again, resulting in a wider range of paging transmissions, resulting in a vicious circle, which may cause paging congestion and waste resources
