Card UE will not switch the PRB of occupancy.ENB1 connects the PRB mark of the UE PRB occupied by silent message through the X2 between base station
Mouth is sent to the base station for not supporting eMTC on periphery.In one embodiment, it can be abutted according to the cell where terminal
The cell for belonging to other base station ranges determines that target does not support the base station of eMTC, such as cell Cell1 and eNB2 coverage area
Interior Cell3 cell is adjacent, and adjacent with the Cell2 cell in eNB3 coverage area, therefore eNB1 is sent to eNB2 and eNB3
Silent message, eNB2 forbid forbidding identifying institute using the PRB for including in silent message in Cell2 cell in Cell3 cell, eNB3
Corresponding PRB.
In such group network system, support that the base station of eMTC can be in the covering of the base station of eMTC terminal arrival support eMTC
When edge, PRB used in the terminal is determined, neighbouring does not support the base station of eMTC according to the quiet of the base station for carrying out self-supporting eMTC
Silent message avoids the PRB occupied using the eMTC terminal, to reduce the generation of co-channel interference, improves signal quality.In eMTC/
It is upper and lower between eMTC and LTE to reduce by adaptive silence/non-silence corresponding PRB resource when LTE takes 1:N networking
Row interference, improves signal quality；The base station PRB resource for not supporting eMTC is made full use of simultaneously, improves network resource utilization, is increased
Add networking flexibility, reduces networking and O&M cost.
The schematic diagram of operation method one embodiment of the group network system of the application is as shown in Figure 9.Base station A is while supporting
The base station of LTE and eMTC, base station B are the base station for only supporting LTE.When base station, A determines the covering marginal position of eMTC terminal base station A
When, in 901, base station A is sent to eMTC terminal stops frequency hopping message, and eMTC terminal can be still using original PRB and base station A
Communication.In one embodiment, the calculating of base station A PRB mark (uplink and downlink) occupied to eMTC terminal is as follows:
Downlink PRB mark: PRBk1DL=NB_BaseDL+i1*6
0≤i1≤Max (NB DL), 0≤k1≤Max (PRB DL) --- --- ----(1)
Uplink PRB mark: PRBk2UL=NB_BaseUL+i2*6
0≤i2≤Max (NB UL), 0≤k2≤Max (PRB UL) --- --- ----(2)
Wherein, the bandwidth of 1 NB (Narrowband, narrowband) be 1.4MHz, 6 PRB=1 NB, as shown in Figure 9.NB_
BaseDL is basis downlink NB mark, i.e. downlink NB serial number minimum value；NB_BaseUL based uplink NB mark, i.e. uplink NB sequence
Number minimum value.NB DL is downlink NB serial number, and Max (NB DL) is downlink NB serial number maximum value；NB UL is uplink NB serial number, Max
(NB UL) is uplink NB serial number maximum value.PRB DL is downlink PRB serial number, and Max (PRB DL) is downlink PRB serial number maximum value；
PRB UL is uplink PRB serial number, and Max (PRB UL) is uplink PRB serial number maximum value.I1, i2, k1, k2 are non-negative integer.
In 902, base station A sends silent message to base station B, and B pause in base station uses the occupied PRB of eMTC terminal, because
This will not be interfered with each other with the communication between A and the eMTC terminal of base station.
In such group network system, supports the base station of eMTC that can calculate the PRB of eMTC terminal occupancy, carry out base station in time
Resource allocation and smoothing improves networking flexibility, reduces networking and O&M cost, is conducive to the deployment of eMTC network and honeycomb Internet of Things industry
