Embodiment
To make the purpose, technical scheme and advantage of the embodiment of the present invention clearer, below in conjunction with the embodiment of the present invention
In accompanying drawing, the technical scheme in the embodiment of the present invention is clearly and completely described, it is clear that described embodiment is
Part of the embodiment of the present invention, rather than whole embodiments.Based on the embodiment in the present invention, those of ordinary skill in the art
The every other embodiment obtained under the premise of creative work is not made, belongs to the scope of protection of the invention.
In the inter-frequency networking scene of current SC-PTM solutions, when the UE positioned at cell edge detects that service is small
, it is necessary to which carry out GAP measurements carries out cell switching or small with the good neighbor cell of selection signal intensity when the signal intensity in area is faint
Area's gravity treatment, now, eNodeB are that terminal configures GAP measurement parameters by RRC, terminal is opened GAP measurements.But in the free time
State and the UE for receiving monitoring group service, do not have RRC to be connected, eNodeB can not be surveyed GAP by RRC between eNodeB
Parameter configuration is measured to UE to carry out GAP measurements, causes UE can not carry out cell reselection.Therefore, the present invention proposes a kind of SC-
GAP measuring methods in the inter-frequency networking scene of PTM solutions, when with eNodeB without the UE that RRC is connected detect service it is small
When the signal intensity in area is faint, UE itself starts GAP measurements, and GAP measurement parameters are configured to physical layer by UE, then basis
GAP measurement parameters carry out GAP measurements, while ensure that GAP measurements do not interfere with UE to the business datum on PCCH, SC-MCCH
Reception, UE can normally receive paging.The method of the present invention is described in detail below.
Fig. 1 is the flow chart of the GAP measuring methods embodiment one provided by the invention based on Idle state, and this method can be with base
Realized in UE, as shown in figure 1, the method for the present embodiment, can include：
S101, the RSRP values for obtaining UE places serving cell；
S102, when UE is in Idle state, judge the difference between the default resident thresholding that RSRP values associate with serving cell
Whether value is less than or equal to preset difference value；If so, S103 is performed, if it is not, not starting GAP measurements；
S103, configuration GAP measurement parameters, and GAP measurements are carried out according to GAP measurement parameters.
Specifically, Reference Signal Received Power (Reference Signal Received Power, abbreviation RSRP) refers to
The average value of the signal power received in all resource particles of the exclusive signal of cell is carried on a Measurement bandwidth, it can
With for judging the power of serving cell signal where UE；The RSRP values of serving cell where UE can be measured periodically.
In the application scenarios of reality, there is different project team, such as metro project, urban project, mountain area project.
In different project team, UE closeness and geomorphic feature is different, therefore, is needed for different project team for UE settings not
Same resident thresholding, i.e. the default resident thresholding in above-described embodiment.The setting principle that thresholding is resident in the present embodiment is as follows：
When UE density is smaller and/or landform is relatively flat, the value of resident thresholding is relatively small, when UE density is larger and/or landform
When complex, the value for being resident thresholding is relatively large.For example, the flatness for being less than pre-set density and/or landform when UE density is big
In default flatness, then the value for being resident thresholding is the first resident threshold value, when UE density is put down more than pre-set density and/or landform
When smooth degree is less than default flatness, then the value for being resident thresholding is the second resident threshold value, and the first resident threshold value is less than second
Resident threshold value.Alternatively, the span for being resident thresholding is -143~-108db.
UE will measure obtained RSRP values compared with default resident thresholding, judge RSRP values and default resident door
Magnitude relationship between the difference and preset difference value of limit.Equally, preset difference value is also to be determined by different project team.This reality
The setting principle for applying preset difference value in example is as follows：When UE density is smaller and/or landform is relatively flat, preset difference value is relative
Greatly, when UE density is larger and/or landform is complex, preset difference value is relatively small.In the present embodiment, preset difference value takes
Value scope is 0~62db.
If UE judges that RSRP values and the difference of default resident thresholding are less than or equal to preset difference value, illustrate what UE was received
The signal quality for the serving cell being currently located is poor, then can start GAP measurements in UE of the Idle state without RRC connections, to survey
Measure the signal quality of neighbor cell.
UE is in Idle state and during without RRC connection, and after UE starts GAP measurements, GAP measurement parameters are configured into UE's first
In physical layer, UE physical layer carries out GAP measurements according to configuration GAP measurement parameters.Alternatively, GAP measurement parameters include GAP weeks
Phase and GAP skews, UE need first GAP cycles and GAP skews to be carried out matching somebody with somebody to postpone that GAP measurements could be carried out after starting GAP measurements.
Measured by GAP, UE can learn the signal quality of neighbor cell, UE according to the signal quality result of neighbor cell,
The top-quality neighbor cell of selection signal carries out cell reselection.
The GAP measuring methods based on Idle state of the present embodiment, UE by the RSRP values according to serving cell where it and
Difference between default resident thresholding judges whether to need to start GAP measurements, and if necessary to start GAP measurements, UE surveys GAP
Parameter configuration is measured to UE physical layer, physical layer carries out GAP measurements according to the GAP measurement parameters of configuration, without passing through eNodeB
GAP measurement parameters are configured, the GAP measurements of the UE without RRC connections in Idle state is realized, avoids UE and monitor group service
Continuity be affected and UE improper off-grid.

Step S202, instruction is set according to the GAP cycles, obtains the GAP cycles.
Specifically, GAP measurements have a both of which, and a kind of measurement pattern is that GAP measurements duration Tgap is 6ms, measurement period
Tperiod is 40ms, i.e., a GAP measurement is carried out per 40ms, every time a length of 6ms during measurement；Another measurement pattern is surveyed for GAP
It is 6ms to measure duration Tgap, and measurement period Tperiod is 80ms, i.e., a GAP measurement is carried out per 80ms, a length of during measurement every time
6ms.Therefore, the GAP cycles could be arranged to 40ms or 80ms.
During specific GAP period assignments, UE instructs firstly the need of the setting for obtaining the GAP cycles, then according to GAP
Cycle sets the GAP cycles carried in instruction to configure the GAP cycles.
Wherein, UE can obtain the setting instruction in GAP cycles by following two modes.
A kind of achievable mode is, after user sets instruction by the auxiliary equipment input GAP cycles, receives auxiliary and sets
The GAP cycles that preparation is sent set instruction.
Specifically, the auxiliary equipment outside UE is wirelessly or non-wirelessly connected with UE, in the user interface left-hand seat of auxiliary equipment
Dynamic input or phonetic entry or selection input GAP cycles, GAP weeks with the GAP cycles that then UE receptions auxiliary equipment is sent
Phase sets instruction.Alternatively, auxiliary equipment can be computer.
Another achievable mode is that GAP cycles per instruction inputting interfaces are shown in UE, and it is defeated by instructing to receive user
Enter the GAP cycles of interface triggering.
Specifically, when UE detects that the difference between the default resident thresholding that RSRP values associate with serving cell is less than or equal to
During preset difference value, UE ejection GAP cycles per instruction inputting interfaces, user is manually entered or voice in GAP cycles per instruction inputting interfaces
Input or selection input GAP cycles, UE receive the GAP cycles that user is triggered by instruction input interface.
