Problems solved by technology

[0004] However, the existing multi-mode terminals cannot not only benefit from the low power consumption and wide coverage characteristics of NB-IoT or eMTC, but also benefit from the high data rate and low latency characteristics of other networks, and the user experience is poor.

Embodiment Construction

[0036] In practical application, the corresponding bandwidth of eMTC UE is 1.4MHz, and data can be sent and received within resources of at most 6 physical resource blocks (Physical Resource Block, PRB) in the same subframe. The bandwidth corresponding to NB-IoT UE is 180KHz, and data can be sent and received within one PRB resource at most in the same subframe. NB-IoT supports the transmission of low-traffic data at a rate below 100Kbps, while eMTC supports a maximum data transmission rate of 1Mbps. eMTC is inferior to NB-IoT in terms of signal coverage depth (eMTC's wall penetration ability is 15dB higher than Cat.4LTE, and NB-IoT's wall penetration ability is 20dB higher than Cat.4LTE), power consumption, and cost. However, the advantages of eMTC are: faster transmission rate, lower delay (100ms level, NB-IoT is second level), support for mobility, frequency division duplex (Frequency Division Dual, FDD), positioning, support for VoLTE voice communication, etc.

Abstract

The invention provides a network mode switching method, a user terminal and a computer readable storage medium. The method comprises the following steps: detecting current network state information and current state information of UE (User Equipment); based on a detection result, judging whether a corresponding network mode switching condition is met or not, wherein the switching between network modes includes: switching between an NB-IoT (Narrow Band Internet of Things) mode and other network modes, or switching between an eMTC (enhanced Machine Type Communications) mode and other network modes; and when the corresponding network mode switching condition is met, switching the network mode of the UE, and enabling the UE to reside to a network of the switched network mode. By applying the above scheme, a multi-mode terminal can not only benefit from characteristics of low power consumption and wide coverage of NB-IoT or eMTC, but also benefit from characteristics of high data rate and low delay of other networks, thereby improving the user experience.

Description

technical field [0001] Embodiments of the present invention relate to the field of communication technologies, and in particular to a network mode switching method, a user terminal, and a computer-readable storage medium. Background technique [0002] With the development of Internet of Things technology, smart terminal devices are becoming more and more popular. In order to accelerate the development of IoT technology, 3GPP introduced enhanced Machine Type Communications (eMTC) and Narrow Band Internet of Things (NB-IoT) technologies in the R13 release. [0003] The eMTC and NB-IoT technologies introduced in the R13 version of 3GPP only support narrowband data transmission, therefore, a User Equipment (UE) supporting eMTC or NB-IoT technology can be called a narrowband terminal. eMTC and NB-IoT technologies focus on low power consumption, wide coverage, and apply enhanced paging cycle (entended Discontinuous reception, eDRX). [0004] However, existing multi-mode terminal...
