Specific embodiment
In practical applications, the corresponding bandwidth of eMTC UE is 1.4MHz, at most in 6 Physical Resource Block in same subframe
Sending and receiving data in the resource of (Physical Resource Block, PRB).The corresponding bandwidth of NB-IoT UE is 180KHz, together
In one subframe at most in the resource of a PRB sending and receiving data.NB-IoT supports 100Kbps or less speed rates low discharge number
According to, and the maximum data transmission rate that eMTC is supported reaches 1Mbps.EMTC is in signal overburden depth (the ability ratio through walls of eMTC
Cat.4LTE promotes 15dB gain, and the ability ratio Cat.4LTE through walls of NB-IoT promotes 20dB), power consumption, in cost not as good as NB-
IoT.But eMTC advantage is: transmission rate faster, more low delay (100ms grades, NB-IoT be the second grade), support mobility, frequency
Divide duplexing (Frequency Division Dual, FDD), positioning, support VoLTE voice communication etc..
EMTC and NB-IoT technology in the elevator or basement of other network coverages such as no LTE, by repeat send,
The methods of narrowband low speed, may be implemented the network coverage.Also, pass through battery saving mode (PSM), discontinuous reception, narrowband low speed, letter
Change the methods of signaling process, supports the UE of eMTC and NB-IoT, the income in terms of low-power consumption can also be obtained.For example, supporting NB-

Terminal is also applicable in the discontinuous reception (entended Discontinuous reception, eDRX) of enhancing, the paging of eDRX
Period maximum was up to 40 minutes, paging cycle configuration in compared to 1.28 seconds or 2.56 seconds etc., and the UE power consumption for being applicable in eDRX is obviously low
Very much.
When the disasters such as earthquake occur, terminal user may be restricted to underground and can not get away, at this time, the consumption of UE
Electricity reduces and the unimpeded of signal becomes most important, especially in terminal power deficiency.Therefore, NB-IoT or eMTC relative to
For other network modes, the characteristic of coverage enhancement and super low-power consumption, the demand being more suitable under certain disaster scenarios its.
However in current communication protocol, LTE and eMTC, NB-IoT think to belong to a network mode, therefore existing
Multimode terminal, when carrying out network mode switching, the switching being usually directed between the network mode of 2G or 3G and LTE mode is led
It causes existing multimode terminal that can not only benefit from the low-power consumption of NB-IoT or eMTC, the characteristic extensively covered, but also benefits from other nets
The characteristic of the High Data Rate of network, low time delay, user experience are poor.
In view of the above-mentioned problems, carrying out network mould to UE the embodiment of the invention provides a kind of network mode switching method
When formula switches, since the switching between the network mode includes: switching or the eMTC of NB-IoT mode and other network modes
The switching of mode and other network modes, therefore multimode terminal can be made both to have benefited from the low-power consumption of NB-IoT or eMTC, extensively cover
The characteristic of lid, and the characteristic of the High Data Rate of other networks, low time delay is benefited from, improve user experience.
To make the above purposes, features and advantages of the invention more obvious and understandable, with reference to the accompanying drawing to the present invention
Specific embodiment explain in detail.
Referring to Fig.1, the embodiment of the invention provides a kind of network mode switching methods, and the method may include following steps
It is rapid:
Step 11, the current status information of current network state information and UE is detected.
In specific implementation, the current network state information may include a variety of, specifically with no restriction.
For example, the current network state information may include: the signal receiving quality that UE is currently resident network, UE energy
Enough being resident the network of other network modes and UE in addition to NB-IoT mode and eMTC mode can receive except NB-IoT mould
The wireless signal of the network of other network modes outside formula and eMTC mode.The network that UE is currently resident be except NB-IoT mode and
Outside eMTC mode when the network of other network modes, service conditions provided by the network that UE is currently resident etc. can also be detected.
In an embodiment of the present invention, other network modes in addition to NB-IoT mode and eMTC mode, may include: 2G's
Global system for mobile communications (Global System for Mobile Communication, GSM), General Packet Radio Service
(General Packet Radio Service, GPRS), enhanced data rates for gsm evolution technology (Enhanced Data
Rate for GSM Evolution, EDGE), TD SDMA (the Time Division-Synchronous of 3G
Code Division Multiple Access, TD-SCDMA) or wideband code division multiple access (Wideband Code Division
Multiple Access, W-CDMA), the long term evolution (Long Term Evolution, LTE) of 4G and 5G etc..Wherein,
LTE herein is the mode in addition to NB-IoT and eMTC.
In specific implementation, the UE current status information also may include a variety of, specifically with no restriction.
For example, the UE current status information may include that the current battery level information of UE and UE are received
The operation instruction informations such as battery saving mode and offline mode.
Step 12, it is based on testing result, judges whether to meet corresponding network mode switching condition.
Wherein, the switching between the network mode includes: switching or the eMTC of NB-IoT mode and other network modes
The switching of mode and other network modes.
In specific implementation, after getting testing result, satisfaction pair can be judged whether based on the network that UE is currently resident
The network mode switching condition answered, to carry out network mode switching to UE.It is understood that between heterogeneous networks mode
Switching, can be set different network mode switching conditions, to provide better network service for UE.
Due in current communication protocol, LTE and eMTC, NB-IoT think to belong to a network mode, thus to UE into
When row network mode switches, related network mode does not include eMTC or NB-IoT mode.But during practical communication,
It being defined in 3GPP TS 36.306, the corresponding terminal class of NB-IoT UE is M2, and the corresponding terminal class of eMTC UE is M1,
The corresponding terminal class of LTE UE is to be numbered from 1, such as downlink class number is to 19, uplink class number to 21, but
Serial number is simultaneously non-fully continuous.In the LTE specification of lowest version, the corresponding terminal class of LTE UE is not compiled separately by upstream and downstream
Number, but the serial number directly since 1, until 12.Since eMTC UE, NB-IoT UE and LTE UE correspond to different terminals
Classification, therefore in an embodiment of the present invention, using the eMTC and NB-IoT and LTE network mode different as UE.Therefore, in this hair
In bright embodiment, when carrying out network mode switching to UE, related network mode may include in eMTC and NB-IoT
It is at least one.
Relative to other network modes, time delay of the UE under NB-IoT and eMTC mode is big, is unable to satisfy middle and high data transfer rate
Business demand, but network coverage dead angle is less, and power consumption is lower, the demand being more suitable under certain disaster scenarios its, therefore can be with
So that UE had not only benefited from the low-power consumption of NB-IoT or eMTC, the characteristic extensively covered, but also benefit from the High Data Rate, low of other networks
The characteristic of time delay improves user experience.
Step 13, when meeting corresponding network mode switching condition, switch the network mode of the UE, and make described
UE is resident the network of the network mode to switching.
In one embodiment of this invention, when the UE resides in other network moulds except NB-IoT mode or eMTC mode

The UE is currently resident in the network of other network modes except NB-IoT mode and eMTC mode, and be resident
Network can only provide emergence call service；
The current state information of the UE meets battery saving mode entry condition or offline mode entry condition.
In specific implementation, first preset duration can be configured according to the actual situation.For example, institute can be set
State the integral multiple that the first preset duration is timer T310 or T310 in LTE.Wherein, timer T310 is wireless for judging
Link failure, value range is from 0 millisecond to 2000 millisecond, 1000 milliseconds of usual value.But it is not covered with if it is elevator
Scene, disengaging elevator may need 1 minute or so, therefore, the first preset duration can be set by 1 minute or even longer.
When UE can not detect other network modes except NB-IoT mode and eMTC mode in the first preset duration
When wireless signal, alternatively, when UE can not be resident the network of other network modes except NB-IoT mode and eMTC mode, or
Person when the network that UE is resident can only provide emergence call service, shows that UE is currently located region not by other network modes

Network, and when the current business of the UE is interrupted because of link failure, it, will based on the system message of the NB-IoT cell got in advance
The network mode of the UE switches to NB-IoT mode.
In specific implementation, NB-IoT mode only provides packet switch (Packet Switch, PS) domain business, therefore described
UE current business can be ps domain business.When UE current business is interrupted because of link failure, can be based on getting in advance
NB-IoT cell system message, the network mode of the UE is switched into NB-IoT mode.
In specific implementation, UE can obtain the system message of NB-IoT cell when meeting the second switching condition.Wherein,
Second switching condition can be set are as follows: the radio signal quality for the network that the UE is currently resident in the second preset duration is held
It is continuous to be deteriorated.
For example, UE can detecte UE and be resident in the second preset duration after entering the poor signals regions such as elevator
The radio signal quality of network is persistently deteriorated, at this point, in order to enhance the covering power of network, it can be by the network mode of the UE
NB-IoT mode is switched to, keeps the communication of UE unobstructed.
In specific implementation, base station can support the ability information of coverage enhancement based on the UE, in advance by respective cell
System message be sent to the UE, and then UE can be when current business be interrupted because of link failure, in time by network mode
NB-IoT mode is switched to, to avoid delay communication.
