Specific implementation mode
As described in the background art, when mobile terminal is located in more severe communication environment, it is possible that all Cell signal quality it is all excessively poor, can cause current service cell that can not continue bearer service, and cannot be satisfied default Switching condition, the case where and then off-line of mobile station being led to, and further lead to not be communicated.
MTC be 3GPP agreements version (release) 13/14 in introduce, mainly for technology of Internet of things, wherein can be with Including enhancing machine type communication (Enhanced Machine Type Communication, EMTC) and micromachine type It communicates (Femto Machine Type Communication, FeMTC), MTC cells are referred to as Internet of Things cell.
MTC cells are intended for machine type terminal, network side is usually only to machine type in initial design The terminal of (Machine Type) issues the information list of MTC cells.MTC is the design based on LTE, but in the present invention, is Apparent simplicity is stated, " mobile network " is 2G, 3G, 4G or 5G network other than MTC.
Through inventor the study found that the communication lowest signal-to-noise of EMTC/FeMTC can reach -15dB, EMTC/FeMTC It can support the communication service of terminal, such as VoLTE business.
In some scenes, MTC cells can have better communication quality, therefore work as compared to the cell of mobile network When the communication quality of the cell of mobile network is poor, the information list of MTC cells is issued to terminal, and switches to MTC cells, it can To avoid off-line of mobile station, communication quality may further be promoted.
It is understandable to enable above-mentioned purpose, feature and the advantageous effect of the present invention to become apparent, below in conjunction with the accompanying drawings to this The specific embodiment of invention is described in detail.
Fig. 1 is a kind of flow chart of cell switching in the embodiment of the present invention, be can specifically include:
In step S11, the information list of MTC cells is issued to terminal, so that the terminal is according to the MTC cells Information list measures the signal quality of MTC cells;
Step S12 receives the signal quality for the MTC cells that the terminal reports;
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.
In step S14, the signal-to-noise ratio of the signal quality and/or the serving cell that determine the serving cell meets Two preset conditions.
Second preset condition is used to indicate serving cell and is unsuitable for carrying out business processing, can pass through Setting signal quality model 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.
After network side instruction terminal switches to MTC cells, terminal can monitor the signal quality of mobile network, To switch back into mobile network.That is, the embodiment of the present invention can also include step S17, if the signal quality of the mobile network Meet the 5th preset condition, it indicates that the terminal switches to the mobile network.5th preset condition is used to indicate mobile network Network is adapted for business processing, can be the condition opposite with the second preset condition.
In embodiments of the present invention, the second preset condition, third preset condition, the 4th preset condition and the 5th default article Part can be compatible with existing agreement, be judged using existing judgement event in agreement.
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 Make trouble part A2, and event A4 occurs.
Due to that can utilize the switching condition in the existing handover event setting embodiment of the present invention, therefore the embodiment of the present invention In cell switching method can be compatible with existing protocol, application cost is relatively low, be applicable in scene it is wider.
