Problems solved by technology

[0004] However, when the UE (user terminal) enters the IDLE (idle) mode, the information of the last cell serving NB-IoTUE reported by the eNB to the MME may be inaccurate, especially for application scenarios where cell reselection occurs, such as bicycles, Logistics tracking, etc., the terminal has already left the original access eNB or cell
In addition, for the NB-IoT terminal at the cell boundary, due to the complex wireless environment, it will also change frequently between the two cells

Abstract

The invention discloses a narrowband Internet of Things terminal, a base station, a paging success rate improving method and a paging success rate improving system. The method comprises the steps thatthe narrowband Internet of Things terminal obtains a terminal residence state; The narrowband Internet of Things terminal determines a current mobility identifier of the narrowband Internet of Thingsterminal according to the resident state of the terminal; The narrowband Internet of Things terminal sends the current mobility identifier to a base station, and the base station determines the current mobility of the narrowband Internet of Things terminal according to the mobility identifier; And the base station judges whether to use a paging optimization function for the narrowband Internet ofThings terminal according to the current mobility of the narrowband Internet of Things terminal. According to the invention, based on the mobility of the NB-IoT terminal, whether the NB-IoT terminaluses a paging optimization function is determined, so the paging success rate of the NB-IoT terminal is improved.

Description

technical field [0001] The present invention relates to the field of mobile communications, in particular to a narrowband Internet of Things terminal, a base station, and a method and system for improving the paging success rate. Background technique [0002] In a communication system, paging is usually used to notify users in an idle state of changes in system information and to notify users of arrival of downlink data. The traditional LTE (Long Term Evolution, long-term evolution) system sends a paging message to the base station through the MME (Mobility Management Entity, mobile management node) through the S1 interface (communication interface between the base station and the packet core network), and includes in the paging message User ID, TAI (Tracking Area Identity, tracking area identifier) ​​list and other information, usually one TAI list includes multiple base station ranges. [0003] For a large number of NB-IoT (Narrow Band Internet of Things, narrowband Inter...
