Description
Technical Field
The present invention relates to the field of mobile communications technologies, and in particular, to a network handover method, an apparatus, a mobile terminal, and a computer-readable storage medium.
Background
With the development of society, communication among people is more and more dependent on mobile terminals, and therefore, the requirement for the communication quality of the mobile terminals is higher and higher.
Today's mobile terminals and operators provide two or more network systems, such as LTE/GSM system, LTE/TD-SCDMA system, WCDMA/GSM system, etc. For example, although the LTE communication technology is more and more widely used, due to network coverage and other reasons, generally, a mobile terminal provides both GSM and LTE communication modes, and an operator also provides both GSM and LTE communication services, so that when LTE signals are poor, GSM can be switched to ensure normal conversation.
Or taking LTE/GSM system as an example, the 3GPP standard specifies that LTE communication is switched to GSM communication when LTE signal strength is smaller than the LTE standard switching threshold and GSM signal is greater than the GSM standard switching threshold. For example, in the mobile terminal, when the signal strength of LTE is less than-115 dBm and the signal strength of GSM is greater than-90 dBm, after the mobile terminal reports the signal strength to the base station, the network type of the mobile terminal is switched to the GSM network.
However, in practical applications, in many cases, the above-mentioned standard still causes a situation of a dropped call due to untimely handover, and obviously, the dropped call will greatly reduce the experience of the user.
Disclosure of Invention
The inventors of the present invention have made intensive studies with respect to the above-described problems, and have found that the above-described criteria for switching by the threshold value is too rigid to be applied to various practical cases.
The inventors of the present invention have found that in practical applications, there may often be cases such as the following: taking LTE/GSM standard as an example, when the signal strength of LTE in a mobile terminal is less than-115 dBm of the standard, for example, -120dBm (satisfying a handover condition), the signal of LTE is very weak at this time and is close to off-line, however, the signal strength of GSM is always less than-90 dBm (not satisfying another handover condition), and therefore, LTE cannot be handed over to GSM all the time, and the LTE call quality is poor finally until the line is dropped.
However, the inventors have found that, in some cases, the mobile terminal can perform communication well even when the signal strength of GSM is slightly lower than-90 dBm, for example, at signal strengths of-92 dBm, -95dBm, and the like.
In view of the above, the present invention provides a network switching method, a network switching apparatus, a mobile terminal, and a computer-readable storage medium.

To solve the problems in the prior art, the invention provides a network switching method, a network switching device, a mobile terminal and a computer readable storage medium; the technical solution of the present invention can be implemented by using related software or hardware, and is described below by embodiments.
In the following embodiments, the mobile device and the operator support two network standards of LTE/GSM for example, but the present invention is not limited to the combination of the two network standards, and may be applied to different network standard combinations, for example, LTE/TD-SCDMA standard, WCDMA/GSM, etc.
Example 1
Fig. 2 is a flowchart of a network handover method according to an embodiment of the present invention. In order to solve the above problems, the technical solution of embodiment 1 of the present invention includes the following steps:
step S21, when the first signal strength value of the first network type currently used is smaller than or equal to the first preset value and the second signal strength value of the second network type currently not used is smaller than or equal to the standard switching threshold value, determine whether a difference between the standard switching threshold value and the second signal strength value is smaller than a second preset value.
Here, taking LTE/GSM combination as an example, for convenience of description, a currently used network standard is referred to as a first network standard, and a currently unused network standard is referred to as a second network standard. Assuming that LTE is currently used, the signal strength of LTE is referred to as a first signal strength, and the signal strength of GSM that is not currently used is referred to as a second signal strength.
When the currently used LTE network system is used, network switching is performed, and it is certainly determined whether the signal strength of the currently used LTE is weakened to affect communication. In this embodiment, the first preset value may be a standard handover threshold of an LTE network system, such as-115 dBm (the preset value may also be referred to as a first standard handover threshold), and if the signal strength of the currently used LTE is less than-115 dBm, it indicates that the communication quality of the LTE is degraded and handover is needed.
In addition, the first preset value may also be smaller than the first standard handover threshold value, and in the case of being smaller than the first standard handover threshold value, it indicates that the current network signal is very bad, and may be close to a dropped line, and an immediate handover is required.
If the first signal strength value is greater than the first preset value, the magnitude of the first signal strength may be continuously monitored, for example, a new first signal strength value is obtained again to determine whether the first signal strength value is less than or equal to the first preset value. For example, if the first signal strength value is much greater than the first preset value, which indicates that the signal strength of the current communication network system is very high, a longer time interval may be set to obtain a new first signal strength value for determination. If the first signal strength value is only slightly larger than the first preset value, a shorter time interval can be set to obtain a new first signal strength value for judgment. Therefore, when the first signal strength value is greater than the first preset value, the first signal strength can be continuously monitored in different manners.
When the signal of the current communication network system is poor and network switching is needed, whether the signal strength of the current unused network system is enough needs to be judged, and switching is needed only if normal communication can be carried out after switching.
According to the existing 3GPP standard, the signal strength of the currently unused GSM is required to be greater than a predetermined second standard handover threshold value, e.g., -90dBm, in order to handover to GSM.
However, as mentioned above, it often happens that the signal strength of GSM is always less than the predetermined second standard handover threshold value, and handover cannot be performed in time, which may result in degradation of communication quality and even a dropped call.
The inventor of the present invention finds that, although the signal strength value of the second network system is lower than the standard handover threshold, the signal strength value of the second network system can often meet the basic call requirement under different practical conditions as long as the signal strength value of the second network system is not too low.
Therefore, according to the technical scheme of the present invention, based on the above actual conditions, it is determined whether the signal strength of the currently unused network system can satisfy the normal call, that is, it is determined whether the signal strength value of the second network system is within a predetermined range lower than the standard handover threshold value.
For example, when the LTE needs to be switched to the GSM, when the signal strength value of the GSM is less than or equal to the standard switching threshold value-90 dBm, it is determined whether the difference between the signal strength values of the standard switching threshold value-90 dBm and the GSM is less than a second preset value, for example, 6 dB. That is, when the difference between the standard handover threshold value of-90 dBm and the signal strength value of GSM is less than the second preset value of 6dB, a certain call quality can be satisfied. If the current GSM signal strength value is-93 dBm, the difference is 3dBm, which is less than the second preset value of 6dB, which indicates that the mobile terminal can normally communicate after switching from the LTE network to the GSM network, and therefore, the subsequent step S22 is continued.
In addition, if the second signal strength value is smaller than or equal to the standard switching threshold value, but the difference between the standard switching threshold value and the second signal strength value is greater than or equal to a second preset value, that is, the difference between the second signal strength value and the standard switching threshold value is large, and the communication requirement cannot be met, new second signal strength values can be continuously obtained at preset time intervals, and whether the standard can be met or not is judged. Or after the preset time, the signal strength of the first network system is obtained again, whether the signal strength is less than or equal to the first preset value is judged, and subsequent obtaining of a new second signal strength value is correspondingly carried out to carry out corresponding judgment action.
In step S22, the current signal status of the mobile terminal is reported to the base station to control the mobile terminal to switch to the second network mode for communication.
For example, when the above current signal state of the mobile terminal is reported to the base station, the mobile terminal reports to the base station in a manner of indicating that the mobile terminal can normally communicate after network handover, so that the base station indicates that handover is required and communication is not substantially affected after handover to GSM, and therefore, the base station notifies the mobile terminal of handover from the LTE network to the GSM network. Therefore, although the signal intensity of the second network system of the mobile terminal does not meet the standard threshold switching requirement, the second network system can be switched to carry out communication, and therefore the disconnection rate is greatly reduced.
In addition, although the above description has been made by taking an example of switching LTE to GSM, the above method may be used for similar problems when the currently used first network scheme is GSM and the unused second network scheme is LTE. When GSM is switched to LTE, the switching can be carried out only if the signal intensity of LTE is larger than a preset standard switching threshold value. However, the following may also occur: GSM signals are weak and LTE signal strength does not exceed a predetermined standard handover threshold, thereby resulting in poor communication quality and even dropped calls. In this case, the switching can also be performed by the similar procedure described above.
For example, when the first preset value of the GSM signal is set to-95 dBm, and when the first preset value is less than-95 dBm, it indicates that the communication quality of the currently used first network system GSM is poor, and there is a need for network switching. Moreover, it is necessary to determine whether the signal strength of the LTE is smaller than a standard handover threshold value of-115 dBm, and whether a difference between the standard handover threshold value of-115 dBm and the second signal strength value (e.g., -117dBm) is smaller than a second preset value (e.g., 6 dBm). In the above example, the difference 2dBm between the standard handover threshold value-115 dBm and the second signal strength value-117 dBm is less than the second preset value of 6dBm, which indicates that the mobile terminal can maintain good communication even after being handed over to LTE. Therefore, the current signal state of the mobile terminal can be reported to the base station, which indicates that the mobile terminal can be switched to the LTE, so that the mobile terminal can be switched to the LTE in time, and the disconnection rate is reduced.
Further, reporting the current signal status of the mobile terminal to the base station may be performed by: reporting the first signal strength value to a base station, and reporting a modified signal strength value obtained by adding an offset value to the second signal strength value to the base station, wherein the modified signal strength value is greater than the standard handover threshold value.
For example, when switching from LTE to GSM, if the signal strength of currently used LTE is less than the first preset value of-115 dBm, for example, -117 dBm. When the current signal state is reported to the base station, the reported signal strength of the LTE is-117 dBm.
The signal strength of the GSM is, for example, -93dBm, which is smaller than a standard switching threshold value-90 dBm, and the difference 3dBm between the standard switching threshold value-90 dBm and the second signal strength value-93 dBm is smaller than a second preset value 6 dBm. At this time, although the signal strength of the second network system GSM of the mobile terminal does not meet the standard threshold switching requirement, normal conversation can be performed.
Therefore, when reporting the signal strength of the GSM to the base station, a certain offset value is added to the current value of-93 dBm, for example, 4dBm is added, and the corrected signal strength value of the GSM after correction is-89 dBm. And reporting the corrected signal strength value of-89 dBm to the base station.
Therefore, the LTE signal strength value and the GSM signal strength value reported to the base station are respectively-117 dBm (smaller than the standard threshold value of-115 dBm) and-89 dBm (larger than the standard threshold value of-90 dBm), so that the switching threshold value required by the standard is met. Therefore, the mobile terminal can be switched to the network system meeting the basic call requirement in time, the disconnection rate is reduced, and the user experience is improved.
The above offset value may be preset, and for example, the above second preset value may be used as the offset value. Specifically, in the technical solution of the present invention, it is required to determine whether a difference between the standard handover threshold value of the second network system and the second signal strength value is smaller than a second preset value, where the second preset value is a value for determining whether the second strength signal is in a predetermined range, and therefore, if the second strength signal is in the predetermined range, the second preset value may be used as the offset value.
For example, taking the case of switching from LTE to GSM as an example, the standard switching threshold value of the second network system GSM is-90 dBm, and the second preset value for determining whether the signal strength of the second network system GSM is within the predetermined range may be, for example, 6 dBm. At this time, the second preset value of 6dBm may be used as the offset value.
When the signal strength of the second network system GSM is-93 dBm for example, and the signal strength of the second network system GSM is within a preset range, reporting a corrected signal strength value of-87 dBm obtained by adding the signal strength value of-93 dBm of the GSM with the second preset value of 6dBm to the base station, and determining that the base station can be switched from LTE to GSM according to the obtained information.
In addition, the second preset value may be a device offset value with respect to the mobile terminal. Specifically, mobile terminals produced by different mobile terminal manufacturers are different, even though different models of mobile terminals provided by the same mobile terminal manufacturer are different. For example, the ability to receive signals varies depending on the type of antenna, the location of the antenna, and the material of the housing, and the signal attenuation of the mobile terminal varies during use by the user. Therefore, the fixed threshold handover method of the existing standard may not be well adapted to different mobile terminals.
Therefore, a mobile terminal manufacturer can test various types of mobile terminals to determine the range of the mobile terminals to communicate within a standard switching threshold value when the mobile terminals need to communicate normally in different network systems. The standard threshold value is subtracted from the measured minimum signal strength required for the call to obtain the device offset value for the mobile terminal. And, the device offset value is taken as the second preset value mentioned above.
Or taking LTE/GSM combination as an example, a manufacturer may test that each type of mobile terminal meets the lowest signal strength requirement of the call requirement in a GSM network system, for example, if the minimum signal strength requirement can be met by more than-98 dBm, and if the standard handover threshold value of GSM is-90 dBm, subtracting the standard threshold value of-90 dBm from the measured minimum signal strength requirement of-98 dBm, where the difference between the two is 8dBm, and thus, taking 8dBm as the device bias value of the mobile device, and setting it as the second preset value. Similarly, the minimum signal strength requirement of the mobile terminal in the LTE network system can also be tested, and similar setting is performed.
In addition, when a user makes a call in different areas, the minimum signal strength requirements that the mobile terminal can satisfy the call requirements are different due to influences of base station settings, terrain, and the like in various places. For example, in different places such as shenzhen, beijing, Chongqing, etc., the mobile terminal is different for the lowest signal strength under various network standards. Therefore, the mobile terminal manufacturer can test the minimum signal strength requirements of different network systems in different places, and correspondingly store the test results, the corresponding network systems and the position marks of the test areas as the area offset table. The mobile terminal may detect the area where the mobile terminal is located through a GPS, for example, and call an area offset value of the area where the mobile terminal is located from the area offset table when it is necessary to determine whether a difference between the standard handover threshold value and the second signal strength value is smaller than a second preset value. Therefore, the configuration parameters of the corresponding area can be called in different areas more pertinently, and the call drop rate is reduced.
When the configuration parameters in the mobile terminal include the device offset value and the zone offset value, the zone offset value is preferentially used because the influence factors of the device itself are already reflected in the test results when the test is performed in each zone.
In the above example, when the difference between the signal strength of the currently unused second network type and the standard handover threshold is within the predetermined range and can meet the basic call requirement, the measured second signal strength is added with the offset value and then provided to the base station, so that the value meeting the handover standard is provided to the base station, and thus, the mobile terminal can perform network handover in time and avoid a dropped call.
However, the current signal status of the mobile terminal may also be reported to the base station in such a way that the mobile terminal after switching the network can perform normal conversation.
When the first signal strength value of the first network system used currently is smaller than or equal to a first preset value, and the second signal strength value of the second network system not used currently is smaller than or equal to a standard switching threshold value but the difference between the standard switching threshold value and the second signal strength value is smaller than a second preset value, it is indicated that the signal strength of the first network system is very poor, a line may be dropped, switching is urgently needed, and the signal strength of the second network system can meet the call requirement although the signal strength of the second network system does not meet the requirement of the standard threshold value. In this case, a special field may be added to the message sent to the base station to indicate that the mobile terminal needs to be handed over immediately and that the communication requirements can be met after the handover. After receiving the message containing the special field, the base station can immediately switch the network type of the mobile terminal to the second network type, thereby avoiding disconnection in time. The specific form of the particular field can be set as desired by those skilled in the art.
The existing network switching standard is too single and rigid, and cannot properly cope with actual conditions such as different mobile terminal types, use areas and the like.
