As used herein, the term "and/or" includes any and all combinations of one or more of the associated listed items.
In order to ensure normal conversation of a mobile terminal, embodiments of the present invention provide a network switching method, an apparatus, and a mobile terminal, wherein the mobile terminal in the embodiments of the present invention may be a device with a voice or video conversation function, such as a mobile phone or a tablet computer. The following detailed description of embodiments of the invention refers to the accompanying drawings.
Example 1
Fig. 1 is a flowchart illustrating a network handover method according to a first embodiment of the present invention. The method is applied to the mobile terminal, and the method flow shown by the embodiment comprises the following steps:
step S11, when the ue is in the 4G network call state and it is detected that the network connectivity performance of the current serving cell is lower than the first connection threshold, send a measurement report to the network-side device in a set manner to accelerate the handover of the network-side device.
The network connection performance may be a received Power of a serving cell or a Reference Signal Receiving Power (RSRP). the mobile terminal being in a 4G network call state may specifically be that the mobile terminal being in a Vo L TE call state, where the call state may include a call making time, a ring time, and a call process.
The first connection threshold may be generally selected empirically, for example, a value (e.g., -110dBm) greater than a network handover threshold is selected, and when the network connection performance is lower than the first connection threshold, it indicates that the current network has weakened although it can also support 4G network call, and it is likely to continue weakening, which may cause call interruption. At this time, the measurement report is transmitted to the network side device in a manner of accelerating the switching of the network side device.
In step S12, when receiving the switching permission command sent by the network side device, the network is switched.
The network handover refers to a handover of a network used for a call from a 4G network to a 2G/3G network, for example, a Vo L TE service call is currently used by the mobile terminal, and the mobile terminal may be handed over from a Vo L TE service to a CS (Circuit Switched ) voice call in an SRVCC manner.
In the method, when the mobile terminal is in a 4G network conversation state and the network connection performance of the current service cell is detected to be lower than the first connection threshold, the network side equipment can acquire the current network connection performance of the mobile terminal in time by sending the measurement report to the network side equipment in a set mode of accelerating the network side equipment switching, the network switching speed is accelerated, the success rate of the network switching is improved, the conversation interruption caused by sudden reduction of the network performance is effectively avoided, and the user experience is improved.
In step S11, the sending the measurement report to the network-side device to accelerate the handover of the network-side device may include: and sending a measurement report to the network side equipment in a mode of accelerating switching by using time trigger and/or event trigger network side equipment.
Specifically, the sending the measurement report to the network side device in a manner of time-triggering the network side device to accelerate handover may include: and sending a measurement report to the network side equipment in a reporting period of less than 100 ms. The method mainly considers that when the network where the mobile terminal is located is rapidly deteriorated, if the reporting period is long, the mobile terminal cannot report the current network connection performance, the network is disconnected, and subsequent network switching cannot be implemented. Based on this, when the network connection performance of the current serving cell connected with the mobile terminal is lower than the first connection threshold, the embodiment of the present invention sets the reporting period of the measurement report to be less than 100ms, and further can send the measurement report to the network side device at a higher frequency.
In order to facilitate the control of the reporting period of the measurement report, a measurement report retransmission timer may be specifically set, and the measurement report retransmission timer is set to be less than 100ms, for example, any value between 40 and 60ms, and preferably 50 ms.
Specifically, the sending the measurement report to the network-side device in a manner that the event triggers the network-side device to accelerate handover may include: (1) when receiving a measurement confirmation message sent by network side equipment, extracting a switching threshold from the measurement confirmation message; (2) when the switching threshold is lower than the second connection threshold, setting the actual switching threshold as the second connection threshold; the second connection threshold is less than or equal to the first connection threshold; (3) and when detecting that the network connection performance of the current service cell is lower than the second connection threshold, sending a measurement report to the network side equipment.
It can be understood that, in the event triggering manner, when the handover threshold in the measurement confirmation message is lower than the second connection threshold, the mobile terminal replaces the handover threshold with the second connection threshold, and actually raises the handover threshold, taking the received power measurement of network connection performance as an example, when the handover threshold in the measurement confirmation message is-116 dBm and the second connection threshold is-110 dBm, the actual handover threshold is set to-110 dBm by applying the event triggering manner, so that once the current network connection performance of the mobile terminal is-110 dBm or lower than-110 dBm, the measurement report is reported to the network side device without waiting for the network connection performance to drop to-116 dBm and then reporting the measurement report, which makes the mobile terminal send the measurement report to the network side device in advance and further complete network handover in advance, and the interruption of the call is avoided to a certain extent.
The two ways of triggering the accelerated switching of the network side device can be used independently or simultaneously.
According to the method, the condition for triggering the network side equipment switching is met as soon as possible in a mode of triggering the network side equipment to accelerate the switching by time and/or triggering an event when the mobile terminal is in a state of poor signal but not triggering the network switching, so that the network switching is carried out in advance, the switching success rate is improved, the call interruption caused by sudden reduction of the network performance is effectively avoided, and the user experience is improved.
Example 2
Fig. 2 is a schematic flow chart of a second embodiment of a network handover method according to the present invention, where the network handover method of this embodiment mainly takes an example of modifying a reporting period of a measurement report, and a method flow shown in this embodiment includes the following steps:
step S21, the mobile terminal accesses the 4G network and initiates a 4G call.
In particular, the mobile terminal may initiate a Vo L TE call, the mobile terminal having been previously registered with the IMS network.
Step S22, the mobile terminal detects whether the network connection performance of the current serving cell is lower than the first connection threshold, if yes, step S23 is executed, and if no, step S22 is repeated.
The detecting action of the mobile terminal for detecting the current serving cell may be implemented by referring to the related technology, for example, the detecting action is performed in a detection period in the related technology, and after the detecting action is performed, it is determined whether the network connection performance of the current serving cell is lower than the first connection threshold.
Considering that the network side device and the mobile terminal need to perform necessary preparation before network handover, for example: selecting a suitable cell in a target network for access, or selecting a suitable base station for access, etc., so that the first connection threshold is usually higher than the actual handover threshold, and when the network connection performance of the current serving cell becomes worse to the first connection threshold, notifying the network side device in time to reserve the preparation time for network handover. The handover threshold is set according to the network side device, the mobile terminal and the environmental condition, and is a variable value, in order to ensure that the first connection threshold is higher than the handover threshold, the present embodiment is set by the network connection performance specifically as the received power, and the first connection threshold is empirically preferably a value between-110 dBm and-115 dBm, and more preferably-110 dBm. When the received power of the current serving cell is below-110 dBm, there is a high probability that the current network will continue to deteriorate, resulting in dropped calls.
Of course, in the implementation manner of selecting other parameters to embody the network connection performance, the first connection threshold may also be a suitable value according to practical experience, which is not limited in the present invention.
Step S23, the mobile terminal sends a measurement report to the network side device with a reporting period less than 100 ms.
The reporting period may be implemented by setting a time parameter of a Timer (Timer) to a value less than 100ms, where the time parameter is the reporting period.
In particular, the timer may be set to any value between 40ms and 60ms, preferably 50 ms.
In actual implementation, two timers may be used, and time parameters of the two timers may be different, where the larger parameter is used when the network connection performance is higher than the first connection threshold (i.e., when the network connection performance is good), and the smaller parameter is used when the network performance is lower than the first connection threshold. For example: the first timer may have a time parameter of 200ms for a better network connection performance (e.g., a received power greater than-110 dBm), and the second timer may have a time parameter of 50ms for a poorer network connection performance (e.g., a received power less than or equal to-110 dBm). By the setting mode of the time parameters, the situation that redundant measurement reports are frequently sent to the network side equipment when the network connection performance is good can be avoided, and the measurement reports can be reported to the network side equipment in time when the network connection performance is poor, so that the success rate of network switching is guaranteed.
The mobile terminal sends a measurement report according to the reporting period in step S23, and reports the network condition of the current serving cell to the network side device more timely, and after receiving the measurement report, the network side device analyzes the current environment where the mobile terminal is located, and issues a measurement confirmation message, where the measurement confirmation message carries the switching threshold and the available frequency point information of the 2/3G network.
Step S24, after receiving the measurement confirmation message sent by the network side device, the mobile terminal sends a measurement report to the network side device when the network connection performance of the current serving cell is lower than the handover threshold in the measurement confirmation message.
After receiving the measurement confirmation message, the mobile terminal extracts a switching threshold and available frequency point information from the measurement confirmation message, wherein the switching threshold is used for triggering the timely reporting of the measurement report, and the available frequency point information is used for the mobile terminal to select the switched target frequency point. For example: when the switching threshold in the measurement confirmation message is-117 dBm, if the receiving power of the current service cell of the mobile terminal is-115 dBm, at this time, if the time does not reach the reporting period, the mobile terminal does not need to report the measurement report, and if the time reaches the reporting period, the measurement report is sent. And if the receiving power of the current service cell of the mobile terminal is-118 dBm, sending a measurement report no matter whether the reporting period is reached in time or not.
And when the measurement reports received by the network side equipment reach a certain number, sending a switching permission instruction to the mobile terminal, and triggering the mobile terminal to perform network switching.
In step S25, the mobile terminal performs network handover when receiving the handover permission command sent by the network side device.
And the mobile terminal switches to the 2/3G network by using the frequency point information in the measurement report.
Step S26, after the network handover is successful, the mobile terminal continues to talk in the network after the handover.
According to the network switching method provided by the embodiment, when the network connection performance of the current serving cell is lower than the first connection threshold, the mobile terminal sends the measurement report to the network side equipment at a higher frequency, so that the network side equipment can issue the measurement confirmation message as soon as possible, and the network switching speed is increased, thereby effectively reducing the probability of switching failure caused by rapid decrease of the network connection performance, improving the success rate of network switching, further ensuring that the call state is continuous and uninterrupted, and improving the user experience.
Example 3
Fig. 3 is a schematic flow chart of a third embodiment of a network handover method according to the present invention, where the network handover method of this embodiment mainly takes modifying a handover threshold as an example for description, and a method flow shown in this embodiment includes the following steps:
step S31, the mobile terminal accesses the 4G network and initiates a 4G call.
Step S32, the mobile terminal detects whether the network connection performance of the current serving cell is lower than the first connection threshold, if yes, step S33 is executed, and if no, step S32 is repeated.
Step S33, the mobile terminal reports the measurement report to the network side device in the set reporting period.
The reporting period is typically set to a few hundred milliseconds. After receiving the measurement report, the network side equipment analyzes the current environment of the mobile terminal and issues a measurement confirmation message, wherein the measurement confirmation message carries the switching threshold and the available frequency point information of the 2/3G network;
step S34, when receiving the measurement confirmation message sent by the network side device, the mobile terminal extracts the switching threshold and the available frequency point information from the measurement confirmation message. The switching threshold is used for triggering the reporting of the measurement report in time, and the available frequency point information is used for the mobile terminal to select the switched target frequency point.
Step S35, when the handover threshold is lower than the second connection threshold, the mobile terminal sets the actual handover threshold as the second connection threshold.
In order to accelerate network handover and ensure that a call is continued without interruption, the mobile terminal in this embodiment does not passively use a handover threshold issued by a network-side device, but introduces a second connection threshold, which may be a value set according to experience, for example: the second switching threshold may be less than or equal to the first connection threshold.
Step S36, when detecting that the network connection performance of the current serving cell is lower than the second connection threshold, sending a measurement report to the network side device.
Because the handover threshold issued by the network side device is usually a handover conservative value, when the network connection performance is not lowered to the handover threshold, the network connection performance is suddenly deteriorated, and the network is disconnected in time of network handover. Therefore, the present embodiment gives the second connection threshold according to practical experience. Taking the received power as an evaluation parameter of the network connection performance as an example, the second connection threshold may be a value between-110 dBm and-115 dBm, for example, -110 dBm. For example: when the handover threshold in the measurement confirm message is-117 dBm, if the reception power of the current serving cell of the mobile terminal is-115 dBm, the second connection threshold is-110 dBm. At the moment, the actual switching threshold is-110 dBm, although-115 dBm > -117dBm, because-110 dBm is taken as the actual switching threshold, and-115 dBm < -110dBm, the measurement report is sent no matter whether the reporting period is reached in time or not. And comparing the situation that the network connection performance is not modified, and sending a measurement report to the network side equipment in advance by the mobile terminal so that the network side equipment can know the current network connection performance of the mobile terminal in time.
And when the measurement reports received by the network side equipment reach a certain number, sending a switching permission instruction to the mobile terminal, and triggering the mobile terminal to perform network switching.
Step S37, when receiving the handover permission command sent by the network side device, the mobile terminal performs network handover using the frequency point information in the measurement report.
In this embodiment, the mobile terminal switches to the 2/3G network by using the frequency point information in the measurement report.
Step S38, after the network handover is successful, the mobile terminal continues to talk in the network after the handover.
According to the network switching method provided by the embodiment, when the network connection performance of the current serving cell is lower than the first connection threshold, the mobile terminal sends the measurement report to the network side equipment according to the set reporting period, and when the switching threshold is lower than the second connection threshold, the mobile terminal sets the actual switching threshold as the second connection threshold.
Example 4
Fig. 4 is a schematic flow chart of a fourth embodiment of the network handover method of the present invention, and the network handover method of this embodiment mainly takes modification of a reporting period of a measurement report and modification of a handover threshold as an example. The method flow shown in this embodiment includes the following steps:
step S41, the mobile terminal accesses the 4G network and initiates a 4G call.
Step S42, detecting whether the network connection performance of the current serving cell is lower than the first connection threshold, if yes, executing step S43, and if no, repeating step S42.
Step S43, the mobile terminal sends a measurement report to the network side device with a reporting period less than 100 ms.
The mobile terminal sends a measurement report according to the reporting period in step S23, and reports the network condition of the current serving cell to the network side device more timely, and after receiving the measurement report, the network side device analyzes the current environment where the mobile terminal is located, and issues a measurement confirmation message, where the measurement confirmation message carries the switching threshold and the available frequency point information of the 2/3G network.
Step S44, after receiving the measurement confirmation message sent by the network side device, the mobile terminal extracts the switching threshold and the available frequency point information from the measurement confirmation message. The switching threshold is used for triggering the reporting of the measurement report in time, and the available frequency point information is used for the mobile terminal to select the switched target frequency point.
Step S45, when the switching threshold is lower than the second connection threshold, the actual switching threshold is set as the second connection threshold.
Step S46, when detecting that the network connection performance of the current serving cell is lower than the second connection threshold, periodically sending a measurement report to the network side device.
As can be seen from the manner of modifying the handover threshold in embodiment 3, when the network connection performance decreases to the second connection threshold but does not decrease to the handover threshold issued by the network side device, the measurement report may be reported to the network side device in time, so as to accelerate the network side device to issue the handover permission instruction. In this embodiment, after receiving the handover confirmation message, the measurement report is still reported to the network side device in a reporting period of less than 100ms, taking the received power as an evaluation parameter of the network connection performance as an example, when the handover threshold in the handover confirmation message is-116 dBm, if the received power of the current serving cell of the mobile terminal is-111 dBm, the second connection threshold is-112 dBm, and the reporting period is 50 ms. According to the method, the actual switching threshold is-112 dBm, -111dBm > -112dBm at the moment, the measurement report is reported to the network side equipment in a period of 50ms, and when the reception power of the current service cell is detected to be-114 dBm, although-114 dBm > -116dBm, the-112 dBm is used as the actual switching threshold, and-114 dBm < -112dBm, the measurement report is sent no matter whether the reporting period is reached in time or not. Compared with the modes of the embodiments 2 and 3, the speed of reporting the measurement report by the mobile terminal is increased, so that the network side equipment can know the current network connection performance of the mobile terminal in time.
And when the measurement reports received by the network side equipment reach a certain number, sending a switching permission instruction to the mobile terminal, and triggering the mobile terminal to perform network switching.
Step S47, when receiving the handover permission command sent by the network side device, the mobile terminal performs network handover using the frequency point information in the measurement report.
In this embodiment, the mobile terminal switches to the 2/3G network by using the frequency point information in the measurement report.
Step S48, after the network handover is successful, the mobile terminal continues to talk in the network after the handover.
According to the network switching method provided by the embodiment, when the network connection performance of the current serving cell is lower than the first connection threshold, the mobile terminal sends the measurement report to the network side equipment in the reporting period of less than 100ms, and when the switching threshold is lower than the second connection threshold, the mobile terminal sets the actual switching threshold as the second connection threshold.
Example 5
The above embodiments are all network handover methods described from the mobile terminal side, and the present embodiment is described by taking an example of network handover, specifically SRVCC-based handover. Referring to a flow chart of the SRVCC-based handover method shown in fig. 5, the method describes an interaction procedure between a user side and a network side with a mobile terminal, specifically a mobile phone, and a network connection performance, specifically a received power, and includes the following steps:
step S51, the handset and the network side device confirm that SRVCC handover is supported.
Step S52, the mobile phone and the network side device establish Vo L TE communication.
In step S53, the handset performs channel measurement.
Step S54, when the channel measurement result is lower than the first connection threshold, the mobile phone reports the measurement report with a reporting period of 50ms to trigger the network switch.
In this embodiment, the first connection threshold is set to-110 dBm. When detecting that the reference signal receiving power of the current service cell is less than-110 dBm, setting the reporting period to be 50ms, and sending a measurement report to the network side equipment by the mobile phone every 50 ms. Taking the reference signal received power of-112 dBm as an example, under the condition that a first connection threshold is defined, the mobile phone reports the measurement report at a higher frequency.
Step S55, after receiving the measurement report, the network side device issues a measurement confirmation message.
The network side equipment sends a measurement confirmation message to the mobile phone, wherein the measurement confirmation message comprises a switching threshold and frequency point information available in 2/3G network, such as-116 dBm, at the moment, the reference signal receiving power of-112 dBm of the current service cell is greater than the switching threshold, namely, the signal strength of the current service cell is superior to the switching threshold issued by the network side, so that the Vo L TE call is maintained.
Step S56, after receiving the measurement confirmation message, the mobile phone sets an actual switching threshold.
The present embodiment also defines a second connection threshold, for example, the second connection threshold is set to-110 dBm. As described above, the switching threshold in the measurement acknowledgement message sent by the network side device is-116 dBm, which is smaller than-110 dBm, and the actual switching threshold is modified to-110 dBm. Taking the reference signal receiving power of-112 dBm as an example, which is less than the second connection threshold of-110 dBm, the mobile phone reports the measurement report at this time, and does not need to report the measurement report after the receiving power is reduced to-116 dBm. Therefore, the mobile phone can send the measurement report in time under the condition of better network condition by improving the actual switching threshold value.
And when the switching threshold in the measurement confirmation message is larger than the second connection threshold, taking the switching threshold in the measurement confirmation message as the actual switching threshold.
Step S57, the mobile phone reports the measurement report with a reporting period of 50ms, and reports the measurement report when detecting that the received power is lower than the actual switching threshold.
Step S58, when the network side device counts the number of measurement reports received within a period of time and reaches a set number, it issues a switch permission instruction.
In step S59, the handset prepares for target channel measurement for handover.
And the mobile phone performs target channel measurement according to the frequency point information of the 2G/3G network in the measurement confirmation message.
Step S60, the network switching occurs between the mobile phone and the network side device.
In step S61, the mobile phone obtains a new encryption key. For specific application of the encryption key, reference is made to related technologies, and details are not repeated in this embodiment.
And step S62, the mobile phone and the network side equipment continue to talk on the circuit domain.
In the method for switching based on SRVCC provided in this embodiment, when the receiving power of the current serving cell is lower than the first connection threshold, the mobile terminal sends the measurement report to the network side device in a reporting period of 50ms, and when the switching threshold is lower than the second connection threshold, the mobile terminal sets the actual switching threshold as the second connection threshold, and when it is detected that the receiving power of the current serving cell can be lower than the second connection threshold, the measurement report can be sent to the network side device in time, so as to accelerate the network switching speed, thereby effectively reducing the probability of switching failure caused by rapid decrease of network connection performance, improving the success rate of network switching, further ensuring that the call state is continuous and uninterrupted, and improving the user experience.
