Embodiment
Applicant finds: having signal coverage areas, when causing the signal strength signal intensity of community to occur to worsen due to landform reason or environmental interference, the signal strength signal intensity of community weakens in wave process, instead of linear taper, and its change curve is as shown in the curve 1 in Fig. 3.
Based on existing cell merge mode, signal strength signal intensity in current service cell is lower than (the A point as in Fig. 1) during first threshold, mobile terminal sends 1F event to network side, network side is after receiving 1F event, start cell handover operations, send pre-switch to this mobile terminal and measure instruction; Mobile terminal, receiving after pre-switch measures instruction, carries out pre-switch measurement (mainly comprise common frequency measurement, shift frequency is measured and isosystem measurement) to around adjacent cell; The signal strength signal intensity of current service cell is fluctuation change, and reach Second Threshold in the signal strength signal intensity of B point current service cell, now mobile terminal sends 1E event to network side, and network side, after receiving 1E event, stops handoff procedure; When again there is fluctuation in the signal strength signal intensity in current service cell, the signal strength signal intensity of current service cell is very likely down to rapidly the 3rd threshold value (the C point as in Fig. 1), because the time is shorter, network side cannot control mobile terminal in time and carry out cell merge, causes mobile terminal to occur call drop.
Here it should be noted that, in 3GPP agreement, define 1F event and 1E event.Wherein, 1F event refers to that a primary pilot signal quality is lower than pre-configured threshold value, can be considered handover request; 1E event refers to that a primary pilot signal quality is higher than pre-configured threshold value, can be considered stopping handover request.Network side, after receiving 1F event, responds this 1F event and starts cell handover operations, mobile terminal is switched to the stronger community of signal strength signal intensity so that follow-up; Network side, after receiving 1E event, responds this 1E event and stops cell handover operations.
Information processing method and the information processor being applied to mobile terminal disclosed by the invention, at mobile terminal to after network side sends 1F event, if the signal strength signal intensity of current service cell recovers the decision threshold most sending 1E event configuration, judge that whether the recovery of current signal strength is only the accidental recovery in signal strength signal intensity deteriorating course, if accidentally recover, then do not send 1E event to network side, mobile terminal can be switched to new community by network side, thus the probability of call drop appears in reduction mobile terminal.
Mobile terminal in the present invention can for mobile phone, there is the panel computer of call function or other have the Wearable of call function.
Below in conjunction with the accompanying drawing in the embodiment of the present invention, be clearly and completely described the technical scheme in the embodiment of the present invention, obviously, described embodiment is only the present invention's part embodiment, instead of whole embodiments.Based on the embodiment in the present invention, those of ordinary skill in the art, not making the every other embodiment obtained under creative work prerequisite, belong to the scope of protection of the invention.
It is the flow chart of a kind of information processing method of disclosure of the invention see Fig. 1, Fig. 1.This information processing method comprises:
Step S11: the signal strength signal intensity detecting current service cell according to prefixed time interval.
Mobile terminal, in running, detects the signal strength signal intensity of current service cell according to prefixed time interval.This prefixed time interval can be definite value, also can be the numerical value according to preset rules change.That is, mobile terminal can the signal strength signal intensity of detection current service cell of timing or not timing.
Step S12: when the signal strength signal intensity of current service cell is less than first threshold, sends 1F event to network side, and the measurement instruction that response to network side sends carries out pre-switch measurement, and measurement instruction is sent after receiving 1F event by network side.
If the signal strength signal intensity of current service cell is lower than first threshold, then mobile terminal sends 1F event to network side.Network side is after the 1F event receiving mobile terminal transmission, and response 1F event sends measurement instruction to the mobile terminal sending this 1F event.Mobile terminal, after receiving measurement instruction, responds this measurement instruction and carries out pre-switch measurement.Wherein, pre-switch measurement comprises common frequency measurement, shift frequency is measured and systematic survey.Certainly, measurement result also can be transmitted to network side by mobile terminal, so that network side carries out subsequent treatment, to determine whether there is the community meeting switching condition in the community around mobile terminal.
Step S13: be more than or equal to Second Threshold in the signal strength signal intensity of current service cell, and mobile terminal is when carrying out pre-switch measurement, judges whether the signal of current service cell meets pre-conditioned.
Wherein, this pre-conditioned average signal strength gradient comprising current service cell current is less than the first numerical value, and the first numerical value is 0 or negative.In the signal strength signal intensity deteriorating course of community, the average signal strength of this community continues to reduce, as shown in the curve 2 in Fig. 3.Average signal strength gradient reflects the situation of change of cell signal within a period of time, if average signal strength gradient is less than 0, illustrates that the signal strength signal intensity of community weakens.In addition, the Second Threshold in the present invention is the decision threshold sending 1E event to network side.
If the signal strength signal intensity of current service cell is greater than Second Threshold, and mobile terminal is carrying out pre-switch measurement, show that mobile terminal sends 1F event to network side, the measurement instruction sent in response to network side carries out pre-switch measurement, and the signal strength signal intensity of current service cell reaches Second Threshold.In this case, judge whether the signal of current service cell meets pre-conditioned, in the present embodiment, specifically judge whether the current average signal strength gradient in current service cell is less than the first numerical value, when the average signal strength gradient current in current service cell is less than the first numerical value, determine to meet pre-conditioned, otherwise determine not meet pre-conditioned.
Step S14: when determining not meet pre-conditioned, sends 1E event to network side, when determining to meet pre-conditioned, does not perform the operation sending 1E event to network side.
If the signal of current service cell meets pre-conditioned, show that the signal strength signal intensity of current service cell is in and weaken state, even if at a time the signal strength signal intensity of current service cell reaches Second Threshold, also there is a strong possibility is accidental phenomenon, therefore the operation sending 1E event to network side is no longer performed, make network side continue to carry out cell handover operations to determine to meet the community of switching condition, control mobile terminal afterwards and switch to this community, reduce the probability of mobile terminal call drop.If the signal of current service cell does not meet pre-conditioned, show that the signal strength signal intensity of current service cell has recovered normal, can ensure the stabilized communication of mobile terminal, therefore mobile terminal sends 1E event to network side, stops cell handover operations to make network side.
Here it should be noted that, scheme disclosed by the invention does not relate to the improvement to network side, and network side see prior art, can not be specifically described here in the carrying out practically process of cell switch process.
Information processing method disclosed by the invention, mobile terminal detects the signal strength signal intensity of current service cell, when signal strength signal intensity in current service cell is lower than first threshold, send 1F event to network side, the measurement instruction that response to network side sends afterwards carries out pre-switch measurement, Second Threshold is more than or equal in the signal strength signal intensity of current service cell, and mobile terminal is when carrying out pre-switch measurement, if the signal of current service cell does not meet pre-conditioned, then send 1E event to network side, cell handover operations is stopped with trigger network side, if the signal of current service cell meets pre-conditioned, show that the signal of current service cell is in and weaken state, therefore the operation sending 1E event to network side is not performed, network side is made to continue to carry out cell handover operations, so that network side controls mobile terminal and switches to this community after determining to meet the community of switching condition, thus reduce the probability of mobile terminal call drop.
The average signal strength of community refers to: the average of the signal strength signal intensity of community in preset time period.Such as: within a time period, the signal strength signal intensity of mobile terminal repeated detection community, obtains m signal strength signal intensity S respectively
(1), S
(2)s
(m), then the average signal strength of this time period Nei Gai community is
In enforcement, the average signal strength of formula 1 calculation plot in preset time period can be utilized.
AS
(i)=(AS
(i-1)* (i-1)+S
(i))/i (formula 1)
Wherein, i=1,2,3 ..., i is the number of times of the signal strength signal intensity of detected cells within this time period, S
(i)be the signal strength signal intensity of the community that i-th time detects, AS
(i-1)for the average signal strength utilizing the signal strength signal intensity detecting the community obtained the 1st time to the i-th-1 time to calculate, AS
(i)for the average signal strength utilizing the signal strength signal intensity detecting the community obtained the 1st time to i-th time to calculate, the namely average signal strength of community within this time period.
Namely, after each detection obtains the signal strength signal intensity of community, all utilize the last average signal strength detecting the signal strength signal intensity obtained and the average signal strength determined before calculating current time.
In implementation process, calculating the current average signal strength gradient in current service cell can in the following way:
First, calculate the average signal strength in first time period, calculate the average signal strength in the second time period.Wherein, first time period is identical with the initial time of the second time period, and the number of times of the signal strength signal intensity of the detection current service cell performed within the second time period is more than the number of times of the signal strength signal intensity of the detection current service cell performed in first time period.
Afterwards, calculate the difference of the average signal strength in the second time period and the average signal strength in first time period, this difference is as the current average signal strength gradient in current service cell.
Here be described in conjunction with an example: calculate the average signal strength between the first moment to the second moment, calculate the average signal strength between the first moment to the 3rd moment afterwards, after 3rd moment was positioned at for the second moment, and from least performing the operation of the signal strength signal intensity of one-time detection current service cell the second moment to the 3rd moment, calculate the difference of average signal strength in two time periods afterwards.
In enforcement, the operation calculating the current average signal strength gradient in current service cell can start to perform after mobile terminal completes base station login.In order to reduce the operand of mobile terminal, thus reducing the power consumption of mobile terminal, also can be configured to after network side sends 1F event, start the operation that execution calculates the average signal strength gradient of current service cell at mobile terminal.
As a kind of preferred implementation, first time period can be configured to the first moment detected the signal strength signal intensity of current service cell moment to the i-th-1 time, and the second time period can be configured to the first moment detected the signal strength signal intensity of current service cell moment to i-th time.Wherein, the last signal strength signal intensity detecting current service cell is designated as the signal strength signal intensity that i-th time is detected current service cell.
See the flow chart that Fig. 2, Fig. 2 are another kind of information processing method disclosed by the invention.This information processing method comprises:
Step S21: the signal strength signal intensity detecting current service cell according to prefixed time interval.
Step S22: when the signal strength signal intensity of current service cell is less than first threshold, sends 1F event to network side, and the measurement instruction that response to network side sends carries out pre-switch measurement, and measurement instruction is sent after receiving 1F event by network side.
Step S23: be more than or equal to Second Threshold in the signal strength signal intensity of current service cell, and mobile terminal is when carrying out pre-switch measurement, judge whether that the current average signal strength gradient in current service cell is less than the first numerical value and signal strength signal intensity standard deviation is greater than second value.
In the present embodiment, judge whether the signal of current service cell meets pre-conditioned being configured to: the current average signal strength gradient in current service cell is less than the first numerical value, and the current signal strength signal intensity standard deviation in current service cell is greater than second value.Wherein, the first numerical value is 0 or negative, and second value is integer, and preferably, second arranges any number be configured in 3-8.
Here it should be noted that, the signal strength signal intensity standard deviation of community characterizes the fluctuation situation of cell signal strength, and signal strength signal intensity standard deviation is larger, represents that current signal fluctuation is more severe, more unstable.
Step S14: when judged result is no, sends 1E event to network side, when judged result is for being, does not perform the operation sending 1E event to network side.
Namely, when not meeting the current average signal strength gradient in current service cell and be less than the first numerical value and the slight standard deviation of signal being greater than second value, 1E event is sent to network side, when the average signal strength gradient that current service cell is current is less than the first numerical value and the slight standard deviation of signal is greater than second value, do not perform the operation sending 1E event to network side.
If the current average signal strength gradient in current service cell is less than the first numerical value, and the current signal strength signal intensity standard deviation in current service cell is greater than second value, show that the signal quality general trend of current service cell declines, mobile terminal is away from current base station, and the jitter of current base station.Therefore, in this case, mobile terminal does not perform the operation sending 1E event to network side.If above-mentioned two conditions do not meet simultaneously, show that the signal strength signal intensity of current service cell has recovered normal, can ensure the stabilized communication of mobile terminal, therefore mobile terminal sends 1E event to network side.
Information processing method shown in Fig. 2 of the present invention is compared with information processing method shown in Fig. 1, at mobile terminal to after network side sends 1F event, if the signal strength signal intensity of current service cell returns to Second Threshold, then judge whether the current average signal strength gradient in current service cell is less than the first numerical value and whether signal strength signal intensity standard deviation is greater than second value, determine whether to send 1E event to network side with this.In the information processing method shown in Fig. 2, assessed by the signal quality of two Rule of judgment to current service cell, determine whether to send 1E event to network side with this, make cell handover operations more accurate.
In information processing method shown in Fig. 2 of the present invention, calculate the step of the current average signal strength gradient in current service cell, adopt described mode above, no longer repeat here.
In enforcement, formula 2 can be utilized to calculate the current signal strength signal intensity standard deviation in current service cell.
