Problems solved by technology

[0002] Since LTE (Long Term Evolution, long-term evolution) generally works in the high-frequency band, there are many coverage blind spots inside buildings and basements. For data service users, especially VoLTE (Voice over LTE, voice service based on IP multimedia subsystem) For users, the limited coverage greatly affects the service experience

Abstract

The invention discloses a user terminal, a base station, a network switching method and a network switching system. The network switching method comprises the steps that a user terminal confirms whether a current network has an enhanced machine type communication capability or not according to a system message; Under the condition that the current network has the capability of enhancing machine type communication, the user terminal judges whether the signal intensity of the serving cell is lower than a preset threshold value or not; And if the signal strength of the serving cell is lower thanthe preset threshold value, the user terminal switches to the enhanced machine type communication system. By adding the eMTC module in the intelligent terminal, a certain coverage enhancement performance gain can be obtained by switching to the eMTC module when the coverage edge is reached under the condition that the cost is slightly increased.

Description

technical field [0001] The invention relates to the field of mobile communication, in particular to a user terminal, a base station, and a network switching method and system. Background technique [0002] Since LTE (Long Term Evolution, long-term evolution) generally works in the high-frequency band, there are many coverage blind spots inside buildings and basements. For data service users, especially VoLTE (Voice over LTE, voice service based on IP multimedia subsystem) For users, service experience is greatly affected due to limited coverage. [0003] 3GPP (3rd Generation Partnership Project, 3rd Generation Partnership Project) has proposed a new feature based on LTE technology, namely eMTC (Enhanced Machine Type Communication), to meet the needs of deep coverage, low power consumption and low cost of the Internet of Things. and other mechanisms can improve coverage by about 15dB. [0004] At present, the industry has developed special chips for eMTC, which are mainly u...
