Step S13 determines the signal quality of the MTC cells, the signal quality of the serving cell of the terminal and neighbour
Relationship between the signal quality in area indicates that the terminal switches to when the relationship between three meets the first preset condition
MTC cells;
Wherein, the serving cell of the terminal is non-MTC cells, and terminal can be with right and wrong machine type terminal, such as can be with
It is the user equipment that mobile phone etc. is mainly used to communication.
Terminal can be that the terminal of communication service is being carried out in connected state, the cell switching side in the embodiment of the present invention
Method can be applied to network side, carry out cell switching by network side instruction terminal, and MTC cells also conduct can be switched to
Target cell further avoided in connected state the case where can promoting the reliability of cell switching, reduce terminal off-grid
The communication service of terminal is interrupted.
The serving cell of terminal can be selected from the cell of 2G, 3G, 4G and 5G mobile network, and serving cell is terminal into the trade
The cell of preceding communication service.Here, 2G, 3G, 4G and 5G mobile network should make amplified interpretation, including usually said 2G communications
System, 2.5G communication systems, 2.75G communication systems and 3G communication systems, 3.5G communication systems, 3.75G communication systems, difference system
The LTE mobile networks of formula, and different 5G networks.
Referring to Fig. 2, the specific implementation of step S11 may include steps of:
Step S111 determines the position of the terminal according to the serving cell of the terminal;
Step S112 issues the information list of the MTC cells apart from the position of the terminal within a preset range.
The position of terminal can be specific geographical location, can also be the position in network, as long as can be according to terminal
Position and preset range determine be possibly used for terminal access MTC cells.
Preset range can be set based on experience value, can be set physical distance as preset range, for example, with
Centered on the position of terminal, the MTC cells in pre-set radius are chosen, the information list of these cells is issued;Or it can be spaced
MTC cells number be unit setting, such as can centered on the MTC cells corresponding to the serving cell of terminal, choose
The cell and the MTC cell adjacent with the cell, issue the information list of these cells.
May include the ID and frequency point of one or more MTC cells with continued reference to Fig. 1, in the information list of MTC cells.
In the specific implementation of step S11, for network side after the information list for issuing MTC cells to terminal, terminal can be according to MTC cells
Information in list measures MTC cells, to learn the signal quality of MTC cells, and measurement result is reported to network
Side.
In the specific implementation of step S12 and step S13, network side is in the signal for receiving the MTC cells that terminal reports
After quality, it may be determined that the letter of the signal quality of the MTC cells, the signal quality of the serving cell of the terminal and adjacent area
It is small to indicate that the terminal switches to MTC when the relationship between three meets the first preset condition for relationship between number quality
Area.
First preset condition is used to indicate the serving cell of terminal and adjacent area is unsuitable for carrying out communication service, and
MTC cells are adapted for communication service.Here, adjacent area include the homogeneous-frequency adjacent-domain of serving cell, alien frequencies adjacent area, homologous ray cell with
And different system cell.
For example, the first preset condition, which may include the serving cell of terminal and the signal quality of adjacent area, is below the first threshold
Value, and the signal quality of MTC cells is higher than second threshold, wherein first threshold and second threshold can be empirical value, the first threshold
Value can be different from second threshold.
The relationship that first preset condition can also include serving cell, adjacent area and MTC cells may include specifically:
After the signal quality of MTC cells is added preset biasing, it is compared with the signal quality of serving cell and adjacent area, MTC is small
The signal quality in area adds the numerical value after preset biasing more than serving cell and the numerical value of the signal quality of adjacent area.
Due to identical in signal quality, the ability that MTC cells carry out business is stronger, therefore to the letter of MTC cells
Number quality is compared with the signal quality of serving cell and adjacent area again after adding preset biasing, can more objective reaction MTC
The situation of the carry out business of cell and serving cell and adjacent area, more accurately carries out cell switching.
If not adding preset biasing to be compared the signal quality of MTC cells, it is possible that serving cell and neighbour
Qu Jun cannot support terminal to be normally carried out business processing, and MTC cells can support terminal to carry out business processing, but due to non-biasing
It sets and is judged, be to be unsatisfactory for the first preset condition, therefore it is small that terminal is not switched to MTC by the relationship erroneous judgement between three
Area, and then lead to the service disconnection of terminal.
As a result, to the signal quality of MTC cells add after preset biasing again with serving cell and the signal quality of adjacent area
It is compared, it is possible to reduce the case where terminal traffic is interrupted promotes the quality of service of terminal.
After the relationship between judged, determining three meets the first preset condition, it can indicate that the terminal switches to
MTC cells.The terminal can be indicated with coverage enhancement Mode A (Coverage Enhancement modeA, CE ModeA)
Or coverage enhancement Mode B (Coverage Enhancement modeB, CE ModeB) accesses the MTC cells.
Whether the specific signal quality that may determine that MTC cells is more than or equal to predetermined threshold value, if it is larger than or equal to default threshold
Value, it indicates that terminal accesses the MTC cells using coverage enhancement Mode A, if the signal quality of MTC cells is less than default threshold
Value, it indicates that the terminal accesses MTC cells using coverage enhancement Mode B.
It, can be more accurate under coverage enhancement Mode B since under coverage enhancement Mode A, message transmission rate is very fast
Carry out data transmission, therefore when the signal quality of MTC cells be more than or equal to predetermined threshold value when, using coverage enhancement Mode A access
MTC cells can more efficiently carry out business processing, when the signal quality of MTC cells is less than predetermined threshold value, using covering
Enhancement mode B accesses the carry out business processing that MTC cells can be more reliable.
As previously mentioned, usually network side does not issue the information list of MTC cells to terminal, only mobile network is issued to terminal
The information list of the cell of network.In embodiments of the present invention, can also include the signal matter to mobile network before step S11
The judgement of amount.
Specifically, can also include step S14 to step S16 before step S11.

It encloses or gives SNR ranges and indicated.
In step S15, determine between the signal quality of the serving cell and the signal quality of the adjacent area of homologous ray
Relationship meets third preset condition.
Third preset condition, which is used to indicate, to be unsuitable for serving cell switching to adjacent area, can pass through neighboring cell signal quality
Relationship between range and or adjacent area and serving cell signal quality is indicated.
Adjacent area may include homogeneous-frequency adjacent-domain and alien frequencies adjacent area, determine serving cell and the signal quality of homologous ray adjacent area
Relational expression can first determine that the signal quality of serving cell and the signal quality of homogeneous-frequency adjacent-domain meet third preset condition, then really
The signal quality for determining serving cell and the signal quality of alien frequencies adjacent area meet third preset condition.
In step s 16, determine that the signal quality of the cell of different system meets the 4th preset condition.
4th preset condition is used to indicate different system cell and is unsuitable for carrying out business processing.Homologous ray is the service with terminal
The identical system of system where cell, can be selected from 2G, 3G, 4G and 5G mobile network, and different system can be selected from 2G, 3G and 4G
Mobile network and be different from the homologous ray.
In specific implementation, step S14 to step S16 can be sequentially executed, sequential steps S14 and step can also be only executed
Rapid S15, or can be judged in another manner, to determine that serving cell is unsuitable for carrying out business processing, and terminal
It is unsuitable for switching to the adjacent area of homologous ray or different system from serving cell.

For example, the second preset condition can be set using the event A2 in the measurement event of LTE, event A3, event are utilized
A4 and event A5 set third preset condition, and the 4th preset condition is set using event B2, default using event B2 settings first
Condition sets the 5th preset condition using event A2.Threshold value in each handover event can be arranged as required to.
Wherein:Event A2 is that serving cell signal quality is less than thresholding (Serving becomes worse than
threshold);
Event A3 is that homogeneous-frequency adjacent-domain signal quality is higher than serving cell signal quality (Neighbour becomes offset
better than PCell/PSCell);
Event A4 is that alien frequencies neighboring cell signal quality is higher than thresholding (Neighbour becomes better than
threshold);
Event A5 is serving cell signal quality less than certain thresholding and neighboring cell signal quality is higher than certain thresholding
(PCell/PSCell becomes worse than threshold1 and neighbour becomes better than
threshold2);
Event B2 is serving cell signal quality less than certain thresholding and neighboring cell signal quality is higher than certain thresholding
(PCell becomes worse than threshold1 and inter RAT neighbour becomes better
than threshold2)。
In an embodiment of the present invention, generation event A2 can be determined in step S14, with the determination serving cell
The signal-to-noise ratio of signal quality and/or the serving cell meets the second preset condition;Event does not occur for determination in step S15
A3, A4 and event A5, with the relationship between the signal quality of the adjacent area of the signal quality of the determination serving cell and homologous ray
Meet third preset condition;Event B2 does not occur for determination in step s 16, is met with the signal quality of the cell of the different system of determination
4th preset condition.At this point, executing step S11 to step S12, in step s 13, using MTC cells as the cell of different system
Judge whether generation event B2 again, meets the first preset condition if event B2 occurs, instruction terminal switches to MTC cells.
When terminal is in MTC cells progress business, the signal quality of mobile network is monitored, if event A2 occurs
Meet the 5th preset condition in step S17, indicates that the terminal switches to the mobile network.
The set-up mode of the first to the 5th preset condition in the embodiment of the present invention is not limited to upper example, can as needed into
Row flexibly setting.
If for example, before executing step S11, it is not carried out step S15 to step S16, then the first preset condition can wrap
It includes:Generation event A2, and judge MTC cells as different system cell, event B2 occurs.
It will be appreciated by persons skilled in the art that when serving cell is the cell of 4G networks, it can also be by MTC cells
As the alien frequencies adjacent area of serving cell, the first preset condition is set using event A4, for example, set the first preset condition as:Hair
