When the network signal of the current network of the terminal is lower than the threshold of the current network and the network signal of the adjacent network is higher than the network threshold of the adjacent network, the terminal is switched from the current network to the adjacent network. For example, the conventional SRVCC (Single Radio Voice Call Continuity) procedure is as follows: the terminal has successfully performed IMS (IP Multimedia Subsystem) service registration, and the network issues an SRVCC handover threshold to the terminal; a terminal is establishing or has established a Voice over LTE (long term Evolution) call on an LTE (long term Evolution) network, and the terminal detects whether LTE cell signals and 2G (Second Generation, Second Generation mobile communication technology)/3G (3rd Generation, third Generation mobile communication technology) cell signals satisfy a threshold: the LTE cell signal is lower than an E-UTRAN (Evolved UMTS Terrestrial Radio Access Network) threshold, the temporary 2G/3G cell signal is higher than a UTRAN (UMTS Terrestrial Radio Access Network) threshold, and if the LTE cell signal is continuously satisfied and reaches a specified time, a measurement report is reported; after receiving the measurement report, the temporary 2G/3G network establishes a voice bearer in a 2G/3G CS (Circuit switched) domain, triggers an SRVCC instruction, switches the terminal to the temporary 2G/3G cell, and continues to perform calling or conversation on the temporary 2G/3G network.
However, the existing network has the problems that the threshold value of the current network where the terminal is located in some areas is too low, when the terminal is in a poor network signal, the quality of a voice packet transmission channel of the terminal is degraded, and a user cannot communicate with an opposite terminal, the terminal cannot be switched to an adjacent network in a delayed manner; or in some cases, due to the decrease of the network service capability, the terminal obtains less channel resource scheduling, the quality of the voice packet transmission path is degraded, the voice is discontinuous, the user experience of the call function is degraded, and the network signal value of the current access network of the terminal is not lower than the current network threshold, so that the terminal cannot be switched to the adjacent network.

Detailed Description
In order to make the technical problems, technical solutions and advantages of the present invention more apparent, the following detailed description is given with reference to the accompanying drawings and specific embodiments.
Please refer to fig. 1, which is a flowchart illustrating a method for switching a terminal between networks according to an embodiment of the present invention. The embodiment of the invention provides a method for switching a terminal between networks, which comprises the following steps:
step 101, acquiring a first signal value of a first network accessed by a terminal and a first signal value of a second network adjacent to the first network;
step 102, determining to be in a handover area for handover from a first network to a second network according to a first signal value of the first network and a first signal value of the second network;

and 104, switching from the first network to the second network according to the second signal value of the first network and the first signal value of the first network.
Specifically, in the handover area, a first signal value of the first network is lower than a first preset value, and a first signal value of the second network is higher than a second preset threshold value; or, in the handover area, a difference between the first signal value of the first network and the first preset threshold is smaller than a second preset value, and the first signal value of the second network is higher than the second preset threshold.
Here, the first preset threshold is a handover threshold of the first network issued by the first network, and the second preset threshold is a handover threshold of the second network issued by the second network, where the first preset value is greater than the first preset threshold, for example, the first preset threshold is-120 dB, and the first preset value is-115 dB; the second preset value may be greater than 0 and less than 3 dB. The first preset value and the second preset value may be set according to the actual service capability of the first network, or may be set based on the actual application experience of the network, and the setting manner of the first preset value and the second preset value is not limited in this embodiment.
In step 103, the step of converting the pre-acquired index information of the terminal during the voice call in the first network into a second signal value of the first network includes:
converting a current RTP (Real-time Transport Protocol) transmission rate and a current RTP packet drop rate which are acquired in advance into a second signal value of the first network.
Here, the voice call quality can be quantifiably measured by the voice data packet transmission performance index, that is, the RTP transmission rate and the RTP packet drop rate are used as index information of the terminal during the voice call in the first network.
Specifically, the step of converting the pre-obtained current RTP transmission rate and the current RTP packet drop rate into the second signal value of the first network may include the following implementation manners.
First implementation
Presetting a mapping table of correspondence between a range value of an RTP transmission rate and a range value of an RTP packet drop rate and a second signal value of the first network, and obtaining the second signal value of the first network according to a table look-up manner, which may specifically include:
searching a first range in which the current RTP transmission rate is located in a preset mapping table, and obtaining a second signal value of the first network corresponding to the first range; and searching a second range in which the current RTP packet drop rate is positioned in the mapping table, and obtaining a second signal value of the first network corresponding to the second range. Wherein, the mapping table is: and mapping tables of corresponding relations between the range values of the RTP transmission rates and the range values of the RTP packet drop rates and the second signal values of the first network.
Here, when any index information of the current RTP transmission rate and the current RTP packet drop rate changes to cause the RTP transmission performance to be degraded, the corresponding second signal value of the first network can be obtained.
In addition, in the above mapping table, the range value of the RTP transmission rate or the range value of the RTP packet dropping rate may include the following forms:
in a first form, the range value of the RTP transmission rate or the range value of the RTP packet drop rate corresponds to the second signal value of the first network, which is a constant value, that is, the mapping table is a certain value mapping table. For example, part of the contents of a first form of one possible mapping table is shown in table 1.
TABLE 1
| RTP Transmission Rate | RTP packet drop rate | Second signal value of the first network |
| <10Kbps | Or>5％ | -119dB |
| <8Kbps | Or>10％ | -120dB |
| <5Kbps | Or>15％ | -121dB |
| …… | …… | …… |
The second signal value of the first network obtained in the first form may be a fixed value obtained by conversion or a fixed operation of an empirical value obtained based on actual usage in the first network.
Or
In a second form, the second signal value of the first network corresponding to the range value of the RTP transmission rate or the range value of the RTP packet drop rate is obtained by subtracting a determined value from the first signal value of the first network, that is, a correction value is set to correct the first signal value of the first network to obtain the second signal value of the first network. For example, part of the contents of one possible mapping table of the second form shown in table 2.
TABLE 2
| RTP Transmission Rate | RTP packet drop rate | Second signal value of the first network |
| <10Kbps | Or>5％ | Subtracting 1dB from a first signal value of the first network |
| <8Kbps | Or>10％ | Subtracting 2dB from the first signal value of the first network |
| <5Kbps | Or>15％ | Subtracting 3dB from the first signal value of the first network |
| …… | …… | …… |
In the second aspect, the determination value subtracted from the first signal value of the first network may be converted based on an empirical value obtained from actual usage in the first network or a determination value obtained through a certain operation.
Or
In the third form, the second signal value of the first network corresponding to the range value of the RTP transmission rate or the range value of the RTP packet drop rate is Average { a dB, last Average }. Wherein, a is a first signal value of the first network, last Average is an Average value of the first signal value of the first network recorded when a range value of an RTP transmission rate or a range value of an RTP packet drop rate reaches a certain range for multiple times, the last Average may be stored in a Read-Only Memory (ROM) of the terminal, and Average { a dB, last Average } is an Average value of a and last Average as a second signal value of the first network. For example, part of the contents of one possible mapping table of the third form shown in table 3.
TABLE 3
| RTP Transmission Rate | RTP packet drop rate | Second signal value of the first network |
| <10Kbps | Or>5％ | Average{-114dB，last Average} |
| <8Kbps | Or>10％ | Average{-116dB，last Average} |
| <5Kbps | Or>15％ | Average{-118dB，last Average} |
| …… | …… | …… |
The second signal value of the first network obtained through the third form can enable the terminal to be more suitable for the network in the area along with the increase of the service time of the terminal, and is helpful for the terminal to eliminate extreme situations.
Or
In the fourth form, the second signal value of the first network corresponding to the range value of the RTP transmission rate or the range value of the RTP packet drop rate is min { a dB, last min }. Wherein, a is a first signal value of the first network, last min is a first signal value of the worst first network among the first signal values of the plurality of recorded first networks when a range value of an RTP transmission rate or a range value of an RTP packet drop rate reaches a certain range for a plurality of times, the last min may be stored in a ROM of the terminal, and min { a dB, last min } is a second signal value of the first network selected as the smallest one of a and last min. For example, part of the contents of a fourth form of one possible mapping table is shown in table 4.
TABLE 4
| RTP Transmission Rate | RTP packet drop rate | Second signal value of the first network |
| <10Kbps | Or>5％ | min{-114dB，last min} |
| <8Kbps | Or>10％ | min{-116dB，last min} |
| <5Kbps | Or>15％ | min{-118dB，last min} |
| …… | …… | …… |
The second signal value of the first network is obtained through the fourth form, so that the terminal can adapt to the network in the area more along with the increase of the service time of the terminal, and once the RTP performance is reduced, the second signal value of the first network is reduced to the lowest history by the terminal immediately, so that the switching process of the terminal between networks is accelerated.
Second implementation
Obtaining the second signal value of the first network according to a linear conversion relation between the second signal value of the first network and the RTP transmission rate and a linear conversion relation between the second signal value of the first network and the RTP packet drop rate, which may specifically be obtaining the second signal value of the first network according to the following formula:
the second signal value 1 of the first network is the RTP transmission rate p, and the second signal value 2 of the first network is the RTP packet drop rate q; and taking the minimum value of the second signal value 1 of the first network and the second signal value 2 of the first network as the second signal value of the first network; wherein p and q are linear scaling factors.
Third implementation
The RTP transmission rate and the RTP packet dropping rate are integrated to perform linear conversion, and a second signal value of the first network is obtained by combining the first signal value of the first network, which may specifically be obtained according to the following formula:
the RTP transmission rate decrease rate L1 is equal to the current RTP transmission rate/the normal RTP transmission rate, the RTP packet drop rate increase rate L2 is equal to the current RTP packet drop rate/the normal RTP packet drop rate, and the second signal value of the first network is equal to the first signal value of the first network L1/L2.
Fourth mode of implementation
By setting a minimum tolerance value, when the RTP transmission performance decreases to the minimum tolerance value, a value lower than a first preset threshold value is obtained as a second signal value of the first network, which may specifically be:
if the RTP transmission rate is less than the first preset tolerance value and/or the RTP packet drop rate is greater than the second preset tolerance value, subtracting a third preset value from the first preset threshold value to obtain a second signal value of the first network.
For example, when the RTP transmission rate is less than 5Kbps or the RTP packet drop rate is greater than 15%, subtracting a third preset value (assumed to be 1dB) from a first preset threshold value (assumed to be-120 dB), and then setting the second signal value of the first network to be-121 dB; for another example, when the RTP transmission rate is less than 7Kbps and the RTP packet drop rate is greater than 10%, the third preset value (assumed to be 1dB) is subtracted from the first preset threshold value (assumed to be-120 dB), and the second signal value of the first network is-121 dB.
In practical application, the step of converting the pre-acquired current RTP transmission rate and the current RTP packet drop rate into the second signal value of the first network may be implemented by selecting any one of the applications, or by using two or more of the implementations in combination.
In step 104, the step of switching from the first network to the second network according to the second signal value of the first network and the first signal value of the first network may specifically include:
replacing the first signal value of the first network with the second signal value of the first network if the difference between the first signal value of the first network and the second signal value of the first network is within a preset range;
in the above step, whether the difference between the first signal value of the first network and the second signal value of the first network is within the preset range is determined, so that the difference between the first signal value of the first network and the second signal value of the first network is not too large, and the situation that the first signal value of the replaced first network (the second signal value of the first network) is excessively corrected relative to the first signal value of the original first network and deviates too much from the real situation is avoided. Specifically, the absolute value of the difference may be taken for judgment, for example, the absolute value of the difference is smaller than X, the value of X may be configured as required, and the value of X is generally recommended to be not more than 2 dB.
And if the first signal value of the first network after replacement is lower than a first preset threshold value and the first signal value of the second network is higher than a second preset threshold value, switching from the first network to the second network.
In the above steps, when the first signal value of the first network after the replacement is lower than a first preset threshold (a handover threshold of the first network) and the first signal value of the second network is higher than a second preset threshold (a handover threshold of the second network), a measurement report is sent to the second network, and a bearer is established with the second network.
The method for switching the terminal between the networks provided by the embodiment of the method of the invention comprises the steps of obtaining a first signal value of a first network accessed by the terminal and a first signal value of a second network adjacent to the first network; determining that the terminal is in a switching area for switching from the first network to the second network according to the first signal value of the first network and the first signal value of the second network; index information of the terminal during voice call in the first network is converted into a second signal value of the first network, and the terminal is switched to the second network from the first network according to the second signal value of the first network and the first signal value of the first network, so that the voice call quality of the terminal in the current network is considered in the process of switching between networks, the problem that the terminal cannot be switched to an adjacent network at a later time under the condition that the quality of a terminal voice packet transmission path is degraded is avoided, and the call function experience is ensured.

Referring to fig. 4 again, it shows a flowchart implementation example of a method for switching a terminal between networks according to an embodiment of the present invention, where the method for switching a terminal between networks includes the following specific steps:
step 401, collecting the RTP transmission rate and the RTP packet dropping rate.
Here, when the terminal performs VoLTE call, the real-time detection module 310 starts to monitor two index information (RTP transmission rate and RTP packet drop rate) of RTP data transmission, and sends the index information to the measurement report modification module 330 every predetermined time.
Step 402, collecting LTE cell signals and adjacent 2G/3G cell signals.
Here, the signal measurement module 320 acquires the LTE cell signal a (first signal value of the first network) and the 2G/3G-adjacent cell signal b (first signal value of the second network), and the radio frequency driver of the terminal transmits the LTE cell signal a and the 2G/3G-adjacent cell signal b to the measurement report modification module 330.
Step 403, determining whether the terminal is in the SRVCC handover area.
Here, the terminal has already obtained the SRVCC handover threshold value issued by the network side from the system message: the E-UTRAN threshold value (the first preset threshold value) is A, and the UTRAN threshold value (the second preset threshold value) is B; if the determination result of the measurement report modification module 330 is that the LTE cell signal a value is lower than a preset network threshold value a '(a first preset value, a' is greater than a), and the temporary 3G/2G cell signal B is higher than B value, or the difference between the LTE cell signal a and the E-UTRAN threshold value a is within 3dB (a second preset value), and the temporary 2G/3G cell signal B is higher than B value, the terminal is currently located in an LTE signal weak area, a 3G/2G signal strong area, and the terminal is located in an SRVCC handover area, execute step 404; otherwise, step 402 is executed again, and the LTE cell signal and the 2G/3G-adjacent cell signal are collected.
And step 404, evaluating an equivalent LTE signal receiving value according to the RTP transmission rate and the RTP packet dropping rate.
Here, the measurement report modification module 330 may convert the RTP transmission rate and the RTP packet drop rate into an equivalent LTE signal reception value (a second signal value of the first network) by any one of the following implementations.
1. Converting the RTP transmission rate and the RTP packet drop rate into equivalent LTE signal receiving values by searching a preset range value of the RTP transmission rate and a mapping table of the corresponding relation between the range value of the RTP packet drop rate and the equivalent LTE signal receiving values;
2. according to a linear operation formula: the equivalent LTE signal reception value 1 is the RTP transmission rate p, the equivalent LTE signal reception value 2 is the RTP packet drop rate q, and then the minimum value of the equivalent LTE signal reception value 1 and the equivalent LTE signal reception value 2 is used as the equivalent LTE signal reception value;
3. according to a linear operation formula: the RTP transmission rate decrease rate L1 is equal to the current RTP transmission rate/normal RTP transmission rate, the RTP packet drop rate increase rate L2 is equal to the current RTP packet drop rate/normal RTP packet drop rate, and the equivalent LTE signal reception value is equal to the LTE cell signal a × L1/L2.
4. According to the minimum tolerance standard, when the RTP transmission rate is smaller than a first preset tolerance value and/or the RTP packet drop rate is larger than a second preset tolerance value, 1dB (a third preset value) is subtracted from the E-UTRAN threshold value A to obtain an equivalent LTE signal receiving value.
Step 405, judging that the difference value between the equivalent LTE signal reception value and the actual measurement value is in the alternative range.
Here, the measurement report modification module 330 determines whether the difference between the equivalent LTE signal reception value and the actual measurement value (LTE cell signal a) is within an alternative range (preset range), that is, whether the absolute value of the difference is less than 2 dB. If yes, go to step 406; otherwise, re-detection is performed.
Step 406, replacing the actual measurement value with the equivalent LTE signal reception value; and when the SRVCC switching threshold value is met, switching from the LTE network to the temporary 2G/3G network.
Here, the measurement report generation module 340 replaces the actual measurement value (LTE cell signal a) with the equivalent LTE signal reception value whose difference from the actual measurement value (LTE cell signal a) is within the replaceable range (preset range) as judged by the measurement report modification module 330; the measurement report generation module 340 compares the equivalent LTE signal receiving value with an E-UTRAN threshold value a, compares the temporary 2G/3G cell signal B with a UTRAN threshold value B, and reports a measurement report to the network when the equivalent LTE signal receiving value is lower than a and the temporary 2G/3G cell signal B is higher than B, that is, the SRVCC handover threshold value is met; after the network establishes the call bearer in the 2G/3G network, the terminal is informed to switch to the adjacent 2G/3G network.
