Description of the drawings
Fig. 1 shows the step flow charts for the alien frequencies inter-system measuring method that the first embodiment of the present invention provides；
Fig. 2 indicates the structural schematic diagram for the alien frequencies isosystem measurement device that the second embodiment of the present invention provides.
Specific implementation mode
To keep the technical problem to be solved in the present invention, technical solution and advantage clearer, below in conjunction with attached drawing and tool
Body embodiment is described in detail.
First embodiment
As shown in Figure 1, the first embodiment of the present invention provides a kind of alien frequencies inter-system measuring method, including：
Step 11, if the signal quality value of the current service cell of terminal is less than predetermined threshold value, the current of terminal is obtained
The target priority of working frequency range；
Step 12, delete operation is carried out to the alien frequencies frequency point of the homologous ray of terminal according to the target priority；
Step 13, the frequency point of the information of the alien frequencies frequency point of not deleted homologous ray and the adjacent different system of terminal is believed
Breath is sent to terminal.
Specifically, terminal receives the information of the alien frequencies frequency point of not deleted homologous ray and the adjacent different system of terminal
Frequency point information after, different-frequency measure is first carried out according to the alien frequencies frequency point of not deleted homologous ray, if in the presence of condition is met
Frequency point then switches to the frequency point for meeting condition of homologous ray；If there is no the frequency points for the condition that meets, according to adjacent different system
Frequency point information carries out isosystem measurement.
For example, the system that terminal is currently located is LTE system, then the homologous ray of terminal is also LTE system.Correspondingly, false
If the adjacent different system of the terminal is 2G systems.
The outdoor of LTE system deploys the double-layer network that F-band adds D frequency ranges mostly at present, specifically, F-band (band
39) range for referring specifically to center frequency point is the frequency range of 1880-1900MHz, and D frequency ranges (band 38) refer specifically to center frequency point
Range is the frequency point of 2575-2615MHz.Wherein F-band is only there are one frequency point, and D frequency ranges include multiple frequency points, and D frequency ranges
Covering is worse than F-band, i.e. the priority of F-band is higher than the priority of D frequency ranges.
Further, step 11 includes in the above embodiment of the present invention：
Step 111, the measurement report that reports of terminal is received, the current service cell of carried terminal in the measurement report
Signal quality value；The measurement report is specifically A2 measurement reports.
Step 112, if the signal quality value is less than predetermined threshold value, the working frequency range of detection terminal；
Step 113, according to the working frequency range detected, the target priority of the working frequency range is determined.
Preferably, the reference signal that the signal quality value of the current service cell is the current service cell receives work(
Rate RSRP values.
Further, in the above embodiment of the present invention, step 12 includes：
Step 121, according to the target priority, determine that priority is less than or equal to the same of the terminal of target priority
The frequency range of system is frequency range to be deleted；
Step 122, all alien frequencies frequency points in the frequency range to be deleted are deleted.
Specifically, when the work at present frequency range of terminal is F-band, it is described according to the target priority, step 121 packet
It includes：
According to the target priority of the F-band, determine that priority is less than or equal to the same of the terminal of target priority
The D frequency ranges and F-band of system are frequency range to be deleted；
Alternatively, when the work at present frequency range of terminal is D frequency ranges, step 121 includes：
According to the target priority of D frequency ranges, determine that priority is less than or equal to the homologous ray of the terminal of target priority
D frequency ranges be frequency range to be deleted.
For example, terminal, when D frequency ranges proceed by eSRVCC and measure, network side only needs to delete the alien frequencies frequency point of D frequency ranges, protects
It stays the alien frequencies frequency point of F-band, terminal first to be measured to F-band, F-band is preferentially switched to when meeting condition；If being unsatisfactory for cutting
Condition is changed, terminal further carries out isosystem measurement.
For another example terminal is when F-band proceeds by eSRVCC and measures, then network side need to delete the institute of D frequency ranges and F-band
There is alien frequencies frequency point, forbid terminal to carry out different-frequency measure, accelerate isosystem measurement, because of effective covering effect of D frequency ranges at this time
Rate is worse than effective covering efficiency of F-band, without being measured to D frequency ranges.
The alien frequencies inter-system measuring method of the alien frequencies frequency point of the frequency range provided in an embodiment of the present invention for deleting low priority can
Terminal to be maintained under original system (LTE network) as far as possible, VoLTE high definition voices are provided for it, are reduced due to eSRVCC
Caused by the probability that declines of voice quality, while alleviating 2G voice loads.
Further, step 13 includes in the above embodiment of the present invention：
Step 131, isosystem measurement message is sent to terminal, carried in the isosystem measurement message not deleted same
The frequency point information of the information of the alien frequencies frequency point of system and the adjacent different system of terminal.Above-mentioned isosystem measurement message is specially B2
Message.
For example, base station, which receives, shows that this cell RSRP is less than thresholding in the A2 measurement reports that terminal reports, base station is then under meeting
Send out the B2 message measured to the different systems of 2G；Before sending the B2 message, base station elder generation detection terminal is in which frequency range；If UE
In low priority frequency range (such as non-F-band), then retain the frequency point letter of F-band while issuing 2G isosystem measurement message
Breath；If UE in high priority frequency range (such as F-band), deletes all except 2G frequencies while issuing 2G isosystem measurement message
Alien frequencies frequency point outside point.
To sum up, in the above embodiment of the present invention, by the priority of terminal work at present frequency range come to the different of homologous ray
Again and again point is deleted, and is carried out the different-frequency measure time to reduce terminal, is reduced the time delay of isosystem measurement, and reduce due to
The probability that voice quality caused by eSRVCC declines.
