Embodiment two

The embodiment of the invention also provides a kind of information processing methods.Fig. 6 is the information processing method of the embodiment of the present invention Second of flow diagram；As shown in fig. 6, the information processing method includes:

Step 501: when mobile terminal activating special sound business, obtaining the first threshold of network side；First threshold The signal strength threshold of value characterization triggering handover event.

Step 502: detection signal strength parameter calculates the difference of the signal strength parameter Yu the first threshold.

Step 503: when the difference of the signal strength parameter and the first threshold is less than first threshold, generating first Prompt information, output show first prompt information；Wherein, first prompt information waits occurring for prompting mobile terminal Network switching, with prompt terminal mobile trend.

Step 504: detecting the first signal strength parameter and second of the first transmission assembly of the mobile terminal respectively The second signal intensive parameter of transmission assembly；Wherein, first transmission assembly is supported data transmitting and is received；Described second passes Defeated component supports data receiver.

Step 505: calculating the difference of first signal strength parameter and the second signal intensive parameter.

Step 506: when the difference of first signal strength parameter and the second signal intensive parameter is not more than second When threshold value, handled by origin operation.

Step 507: when the difference of first signal strength parameter and the second signal intensive parameter is greater than the second threshold When value, first signal strength parameter and the second signal intensive parameter.

Step 508: when the signal strength of first signal strength parameter characterization is better than the second signal intensive parameter When the signal strength of characterization, using first signal strength parameter as the signal evaluation result for being sent to network side.

Step 509: when the signal strength of first signal strength parameter characterization is weaker than the second signal intensive parameter When the signal strength of characterization, to first signal strength parameter and the second signal intensive parameter press default weighting algorithm into Row weighting processing, using weighting processing result as the signal evaluation result for being sent to network side.

In the present embodiment, in the present embodiment, the special sound business is specifically as follows VoLTE voice service, such as language Sound business, video traffic etc. need the business of transmitting multimedia data.When the special sound business described in the mobile terminal activating, one The aspect mobile terminal establishes connection by local network side and correspondent network side and opposite end mobile terminal, on the other hand, institute It states mobile terminal and obtains the first threshold that local network side is sent, the signal strength of the first threshold characterization triggering handover event Thresholding；It is to be understood that the first threshold is that mobile terminal judges whether to trigger the signal strength threshold of SRVCC switching, i.e., When mobile terminal detects that current channel strength reaches the first threshold, the mobile terminal believes itself current network Number quality is assessed, and assessment result is reported to network side, issues switching command to mobile terminal by network side.Specifically, The mobile terminal can obtain the first threshold by baseband chip or modem bottom.

In the present embodiment, when output shows first prompt information, the current signal strength of mobile terminal is shown Close to the signal strength threshold of triggering handover event, it is understood that be currently at the side of the overlay area VoLTE for mobile terminal Edge also indicates that the signal strength of mobile terminal decays again and is a little just likely to triggering SRVCC switching.In such a scenario, described The mobile terminal network signal quality current to itself is assessed, and assessment result is reported to network side, by network side to shifting Dynamic terminal issues switching command.Mobile terminal receive can search for after switching command 2G or 3G cell specified in switching command into Row network switching is to continue talk business.Here, the assessment result of the network signal quality of mobile terminal reporting will affect It is whether smooth to whole network handoff procedure.

Under normal conditions, mobile terminal carries out signal strength measurement by two transmission assemblies；The transmission assembly is specific It can be antenna.Wherein, the first transmission assembly supports the transmitting and receive capabilities of data, and the second transmission assembly only supports data Receive capabilities.As an implementation, the signal strength parameter of transmission assembly can be indicated by received signal strength indication, then One signal strength parameter can indicate that second signal intensive parameter can connect by second by the first received signal strength indication (rx0) Receiving signal strength indication (rx1) indicates.The difference for calculating rx0 and rx1, when the difference of rx0 and rx1 is not more than second threshold, institute Stating mobile terminal can be handled according to original signal evaluation process and report flow.Wherein, the second threshold is for example 6dBm。

When the difference of rx0 and rx1 is greater than second threshold, further compare rx0 and rx1.It include two kinds in the present embodiment Situation, the first situation are when rx0 is better than rx1, i.e. the signal strength of the first transmission assembly is better than the letter of the second transmission assembly When number intensity, since the first transmission assembly includes that transmitting and receive capabilities report at this time based on the received signal strength of rx0 Signal evaluation result be subject to rx0, i.e., using first signal strength parameter as the signal evaluation for being sent to network side As a result.It is can guarantee before SRVCC switching occurs in this way, emitting performance maintains a preferable range, will be on handover event Offer network side.

Second situation is when rx0 is weaker than rx1, i.e. the signal strength of the first transmission assembly is weaker than the second transmission assembly When signal strength, because the first transmission assembly has emission function, and the second transmission assembly does not have emission function.To guarantee Switch preceding first transmission assembly and have enough emitting performances, and avoids the received signal strength because of the first transmission assembly too fast SRVCC switching occurs lower than the signal strength threshold value of triggering handover event for ground, need at this time to the first transmission assembly and The received signal strength of first transmission assembly, which is done, to be had the right to be added, and specific weighting algorithm is mainly according to the reception of the first transmission assembly The rate of decay of signal strength as the factor carry out signal evaluation, when the first transmission assembly received signal strength decaying it is too fast, Then assessment signal can than the first transmission assembly received signal strength faster, to reach the emissivity for switching preceding first transmission assembly It is able to satisfy to network side and reports handover event, so that the forward direction network side for making mobile terminal decay to call drop in network signal is sent When carrying out special sound business, there is a situation where call drops as a result, avoiding mobile terminal for signal evaluation, promote the communication body of user It tests.

Specifically, the default weighting algorithm meets following formula (1):

rx_eva’=rx_eva-(B₁-B₀)/(x-1) (1)

Wherein, rx_eva’Indicate weighting processing result；B₁Indicate the first signal strength parameter；B₀Indicate that last detection obtains First transmission assembly signal strength parameter；X is weighted factor；rx_evaMeet following formula (2):

rx_eva=[A₁+(x-1)B₁]/x (2)

Wherein, A₁Indicate second signal intensive parameter.

Specifically, with A₀Indicate last detected second transmission assembly signal strength parameter, A₁It indicates current to obtain The second transmission assembly second signal intensive parameter；B₁Indicate the first signal strength ginseng of the first transmission assembly currently obtained Number；B₀Indicate the signal strength parameter of last detected first transmission assembly.The signal of consideration can worse and worse, That is A₀>A₁, signal evaluation at this time will be to rx in principle₀By disturbing, then the weighted results of signal strength evaluation are rx_eva=[A₁+ (x-1)B₁]/x；Wherein, x is weighted factor, is determined according to the difference between rx1 and rx0, theoretically between rx1 and rx0 Difference is bigger, and x is also bigger；Correspondingly, the difference between rx1 and rx0 is smaller, x is also smaller.In view of the rate of decay of rx0, then Signal evaluation result before switching should be rx_eva’=rx_eva-(B₁-B₀)/(x-1).Theoretically, rx0 attenuation degree is bigger, letter The decaying of number assessment result is bigger, supports emitting performance to make rx0 possess enough signal strengths before the handover.Wherein, x Numerical value can be pre-configured with by factors such as time, scene, geographical location, used carrier networks and appropriate adjustment.

The detection processing unit 62 is also used to detect the first signal strength parameter of first transmission unit 64 respectively And second transmission unit 65 second signal intensive parameter；Compare first signal strength parameter and the second signal is strong Spend parameter；When the difference of first signal strength parameter and the second signal intensive parameter is greater than second threshold and described It, will be described when the signal strength of first signal strength parameter characterization is better than the signal strength of the second signal intensive parameter characterization First signal strength parameter is as the signal evaluation result for being sent to network side；It is also used to when first signal strength parameter It is greater than the signal strength that second threshold and first signal strength parameter characterize with the difference of the second signal intensive parameter When being weaker than the signal strength of the second signal intensive parameter characterization, to first signal strength parameter and the second signal Intensive parameter is weighted processing by default weighting algorithm, using weighting processing result as the signal evaluation for being sent to network side As a result.

Embodiment three is different from, in the present embodiment, when the output display unit 63 output display the first prompt letter When breath, show that the current signal strength of mobile terminal has been approached the signal strength threshold of triggering handover event, it is understood that be Mobile terminal is currently at the edge of the overlay area VoLTE, also indicates that the signal strength of mobile terminal decays again and a little just very may be used SRVCC switching can be triggered.In such a scenario, the detection processing unit 62 network signal quality current to itself is commented Estimate, assessment result is reported to network side, switching command is issued to mobile terminal by network side.Mobile terminal receives switching and refers to 2G or 3G cell specified in switching command can be searched for after order carries out network switching to continue talk business.Here, mobile The assessment result for the network signal quality that terminal reports influences whether whole network handoff procedure is smooth.

Under normal conditions, mobile terminal carries out signal strength measurement by two transmission units；The transmission unit is specific It can be antenna.Wherein, the first transmission unit 64 supports the transmitting and receive capabilities of data, and the second transmission unit 65 only supports number According to receive capabilities.As an implementation, the signal strength parameter of transmission unit can be indicated by received signal strength indication, Then the first signal strength parameter can be indicated by the first received signal strength indication (rx0), and second signal intensive parameter can pass through Two received signal strength indications (rx1) indicate.The difference for calculating rx0 and rx1, when the difference of rx0 and rx1 is not more than second threshold When, the mobile terminal can be handled according to original signal evaluation process and report flow.Wherein, the second threshold Such as 6dBm.

When the difference of rx0 and rx1 is greater than second threshold, the detection processing unit 62 further compares rx0 and rx1.
