M2M-UE is switched to corresponding up after the up and/or downlink dedicated working frequency range information after obtaining change
Special working frequency range and/or downlink dedicated working frequency range.It is described individually below：
First, when up special working frequency range changes：
So that the center frequency point that up special tool makees frequency range changes as an example, it is assumed that up after being adjusted comprising center frequency point
The SIB of special work band information, such as SIB2, occur in descending n-th subframe, then, and new up special working frequency range comes into force
The sub-frame of uplink of time Ying (n+4) mod 10, i.e. M2M-UE needs to complete work in the sub-frame of uplink of (n+4) mod 10
Frequency range switches, and sends uplink channel information to base station on new up special working frequency range.Wherein, mod symbols represent to take
Modular arithmetic.Assuming that n value is 0 to 9, (n+4) mod 10 is meant that：If n+4 be less than 10, take n+4, if n+4 be equal to 10 or
More than 10, then (n+4) divided by 10 remainder are taken, when not having remainder, 0 is taken.
In a kind of embodiment, as long as terminal completes working frequency range switching in the sub-frame of uplink of (n+4) mod 10.
In another embodiment, in order to prevent loss of data, as shown in Figure 10, the sub-frame of uplink of (n+4) mod 10 is divided two
First period that G is designated in period, figure is used as being designated V second period in switching time, figure sending out
Uplink channel information is sent to base station.In the first time period, M2M-UE completes frequency range switching, without sending information, to ensure not having
There is information loss.It should be noted that be designated in figure in V second period can not also send uplink channel information to
Base station, if send uplink channel information depending on the need for concrete scene.
2nd, when downlink dedicated working frequency range changes：
So that the center frequency point that descending special tool makees frequency range changes as an example, it is assumed that descending after being adjusted comprising center frequency point
The SIB of special work band information, such as SIB2, occur in descending n-th subframe, then, and new downlink dedicated working frequency range comes into force
The descending sub frames of time Ying (n+1) mod 10, i.e. M2M-UE is needed on the descending sub frames of (n+1) mod 10 under new
Descending channel information is received on the special working frequency range of row.
In order to prevent loss of data, as shown in figure 11, the sub-frame of uplink of (n+1) mod 10 is divided into three periods, figure
In be designated G first period and be used as switching time, be designated in figure in C second period and receive what base station was sent
It is designated in downlink control channel information, figure in D the 3rd period and receives the downlink data that base station is sent.The very first time
In section, M2M-UE completes frequency range switching, without receive information, to ensure that no information is lost.
Further, if up or the center frequency point of downlink dedicated working frequency range changed, base station is also wide
Broadcast comprising change after up or downlink dedicated working frequency range information new SIB, but M2M-UE in preset time not
The new system information block (SIB) is received, then M2M-UE switch operating frequency ranges in the following manner：
If although M2M-UE fails that the new SIB can be received in the scheduled time, but can continue to it is current it is descending specially
With receive information on working frequency range, then illustrate that downlink dedicated working frequency range does not change, M2M-UE can continue in downlink dedicated
The SIB of next dispatching cycle, such as SIB2, or the SIB2 in cycle further below are received on working frequency range, to reacquire change
Up special work band information afterwards.
If M2M-UE can not receive any layer one or layer two within current downlink dedicated working frequency range the preceding paragraph time
Information, illustrates that downlink dedicated working frequency range is changed, then M2M-UE can switch back into downlink center working frequency range, and repetition is held
Row step 101-105, so as to switch on the special working frequency range of new downlink and uplink.Generally, layer one is physical layer, and layer two
