Detailed description of the invention

It is more fully described the exemplary embodiment of the present invention below with reference to accompanying drawings.Although accompanying drawing shows The exemplary embodiment of the present invention, it being understood, however, that may be realized in various forms the present invention and should be by Embodiments set forth here is limited.On the contrary, it is provided that these embodiments are able to be best understood from this Invention, and complete for the scope of the present invention can be conveyed to those skilled in the art.

Embodiment

Owing in prior art, multiple LTE module of many cards multithread terminal are close together, have similar new To quality, it is impossible to if controlling it, it is likely that multiple LTE module all access in same community, The ascending performance of many cards multithread terminal can not be given full play to, such as: many cards of integrated 2 LTE module are many Stream terminal, not good enough in the community of double-layer network, although also to be promoted by up MU-MIMO pairing Upstream rate, but promote effect and be about 10%, extremely limited, can not show a candle to two LTE module and be respectively connected to The lifting effect of different districts.In order to solve this problem, as it is shown in figure 1, The embodiment provides A kind of control method accessing community, is applied to the multithread terminal of card more than, including:

Step 10: receive the network quality parameters of each community that each LTE module reports；Wherein, each Community includes Serving cell and the adjacent cell being currently accessed；Many cards multithread terminal includes multiple LTE module.

Here, multiple LTE module periodically report the Serving cell being currently accessed self detected respectively With the network quality parameters of adjacent cell, this network quality parameters includes can be as assessment current network conditions Parameter, such as: Reference Signal Received Power RSRP, reference signal launch power CRS and signal to noise ratio etc..

Step 20: according to network quality parameters, calculates LTE module and is respectively connected to the handling capacity of each community And throughput gain.

Here, after receiving the Serving cell or adjacent cell network quality parameters that each LTE module reports, will Each network quality parameters substitutes in preset function and calculates, and obtains arbitrary LTE module and is respectively connected to not The handling capacity of same community or throughput gain.Wherein, above-mentioned preset function is generally directed to network quality parameters Monotonic function, such as, when network quality parameters is more excellent, anticipated gulp down according to what this preset function calculated The amount of telling or throughput gain are the biggest.The embodiment of the present invention provides some further below and may be used for the present invention Concrete function formula, certain those skilled in the art can also use other formula of the prior art to carry out Calculate.

Further, above-mentioned network quality parameters includes: Reference Signal Received Power RSRP and reference signal Launching power CRS, the preset function calculating the handling capacity that LTE module accesses community has multiple choices, this Only illustrating with typical T function in embodiment, wherein, LTE module accesses the handling capacity of a community The formula of T (RSRP) is:

As RSRP >=CRS+IOT-123,

T (RSRP)=Min (T_peak,a+c*(RSRP-CRS-IOT))

When RSRP < during CRS+IOT-123,

T (RSRP)=Max (0, b+d* (RSRP-CRS-IOT))

Wherein T (RSRP) is monotonically increasing function, when same frequency measurement obtains multiple RSRP, then selects The value that RSRP-CRS is maximum.Constant 123 in RSRP >=CRS+IOT-123 is to commonly use empirical value； In formula, T_peakRepresent Serving cell or the upstream peak speed of adjacent cell, under current 3D1U proportioning, T_peak Represent the interference factor of Serving cell or adjacent cell for 100Mbps, IOT, generally may be configured as 5, a and b table Show preset throughputs constant, and be associated with the frequency of the community accessed, usual empirical value a=64.22, B=43.78；C and d represents preset throughputs weight coefficient, usual empirical value c=0.508, d=0.34.

Further, the preset function calculating the throughput gain that LTE accesses community also has multiple choices, The present embodiment only illustrates with typical G-function.Wherein, arbitrary LTE module access one is calculated little The formula of throughput gain G (RSRP) in district is:

As RSRP >=CRS+IOT-112,

G (RSRP)=Min (100%, a ' %+c ' * (RSRP-CRS-IOT))

When RSRP < during CRS+IOT-112,

G (RSRP)=Max (0, b ' %+d ' * (RSRP-CRS-IOT))

Wherein G (RSRP) is monotonically increasing function, and the constant 112 in RSRP >=CRS+IOT-112 is One commonly uses empirical value, and in formula, a ' and b ' represents default throughput gain constant, and the frequency of the community with access Being associated, usual empirical value is a '=280.2%, b '=617%；C ' and d ' represents that presetting throughput gain weighs Weight coefficient, usual empirical value is c '=0.02, d=0.05.

Step 30: according to Serving cell and adjacent cell, determines the attainable different accesses of multiple LTE module Cell combination, and handling capacity and the throughput gain of each community is accessed according to LTE module, calculate respectively Under different access cell combination, the anticipated total throughout value of multiple LTE module.

According to Serving cell and adjacent cell, multiple different access cell combination be can be combined, according to above-mentioned calculating The LTE module obtained accesses handling capacity and the throughput gain of each community, calculates respectively and accesses little in difference Anticipated total throughout value under district's combination.

Further, according to above-mentioned calculated arbitrary LTE module access different districts handling capacity and Throughput gain, calculates the anticipated total throughout value of multiple LTE module according to the following formula:

$\mathrm{Tph}=\underset{i}{\mathrm{\&Sigma;}}T\left(\mathrm{RSRPi}\right)*(1+G^{\&prime;}\left(\mathrm{RSRPi}\right))$

In formula, Tph represents a kind of anticipated total throughout value accessed under cell combination, and i represents that this access is little Each community that under district's combination, multiple LTE module access, T (RSRPi) represents that a LTE module accesses Throughput value during i-th community, G ' (RSRPi) represents the throughput gain value that i-th community is corresponding； Wherein, when LTE module accesses i-th community, the value of G ' (RSRPi) is 0, when two or When two or more LTE module accesses i-th community, G ' (RSRPi)=G (RSRPi), this is owing to working as If existing two LTE module access in same community, then this community continues to increase the LTE accessed Module, can not bring the lifting of handling capacity.

Step 40: choose the access cell combination corresponding to maximum in anticipated total throughout value, as connecing Enter the mode decision scheme of community.

In order to promote handling capacity to greatest extent, then should choose in anticipated total throughout value corresponding to maximum Access cell combination as the mode decision scheme accessing community.

Further, cause frequently switching the mode decision scheme of access community in order to avoid single measurement result fluctuates Problem, the anticipated total throughout value under cell combination can be accessed according to the most calculated each, determine Maximum anticipated total throughout value, and by the access cell combination corresponding to the anticipated total throughout value of this maximum, It is defined as candidate and accesses cell combination；Access little when same access cell combination continuous several times is confirmed as candidate During district's combination, this candidate is accessed the cell combination mode decision scheme accessing community as each LTE module. Preferably, the candidate that continuous 3 times are chosen can be accessed cell combination identical time, this candidate is accessed community group Cooperation is mode decision scheme.In order to ensure to adjust promptness, the situation of LTE module off-grid should be avoided as far as possible, The cycle of consecutive sentence is usually arranged as second level, such as: 15 seconds, when many cards multithread moving velocity of terminal is During 30km/h, corresponding distance is 125m, so combines situation about choosing continuous 3 times, and corresponding many cards are many Stream terminal displacement is 375, is approximately the covering radius of single subdistrict, can avoid from double-deck networking region The problem causing LTE module off-grid because of frequency locking when entering monolayer networking region.

Further, after step 40 determines the step of the mode decision scheme accessing community, this control method Also include: send corresponding frequency locking order according to mode decision scheme to each LTE module in addition to main LTE module, So that LTE module accesses corresponding community.Wherein, during main LTE module is multiple LTE module. Conventional control terminal accesses the method for community and includes locking cell id and frequency locking point, and general LTE module all has Ready-made incoming order.Although lock cell id can directly control the access community of LTE module, but can cause Cannot switch, affect mobility, therefore should not use.Consider each LTE module tool in many cards multithread terminal There is similar channel environment, if access frequency point is identical, then can access same community, therefore by lock in probability ground greatly Frequency mode can control the access community of LTE module, but because cannot be carried out different-frequency measure after frequency locking point, Therefore for ensureing that many cards multithread terminal can know the RSRP of other frequency, should choose in multiple LTE module One main LTE module not frequency locking.

Further, also included before sending corresponding frequency locking order to each LTE module: at multiple LTE Module is chosen a LTE module as main LTE module, the most main LTE module and other LTE module There is no difference.

The control method accessing community of the present invention, selects each LTE module based on throughput-maximized principle Access community, the network quality parameters reported according to each LTE module, calculate be respectively connected to each community Handling capacity and throughput gain, calculate different access under cell combination respectively according to handling capacity and throughput gain Anticipated total throughout value, by selecting the access cell combination that the maximum in anticipated total throughout value is corresponding to make For accessing the mode decision scheme of community, can realize automatically adjusting connecing of each LTE module according to real network situation Enter community, promote the ascending performance of many cards multithread terminal.

Due to the difference of the integrated LTE module number of many cards multithread terminal, the combination accessing community is different, for Readily appreciate, will illustrate with the example below:

Example one:

When many cards multithread terminal includes two LTE module,

If only recording a frequency, the Serving cell being currently accessed the most only detected, then skip this judgement, Do not change current access way；

If recording two and above frequency, Serving cell the most not only being detected, also detecting that one or more Adjacent cell, if the RSRP of Serving cell is RSRP1, in adjacent cell, RSRP maximum is RSRP2.

When two LTE module equal access service communities, it is contemplated that total throughout value Tph=T (RSRP1) * (1+G(RSRP1))；

When two LTE module are respectively connected to Serving cell and adjacent cell, it is contemplated that total throughout value Tph=T (RSRP1)+T (RSRP2)；

Wherein, T (RSRP1) represents the handling capacity of access service community, and G (RSRP1) represents access clothes The throughput gain of business community, T (RSRP2) represents the handling capacity accessing adjacent cell, compares the most above-mentioned calculating The value of the Tph arrived, chooses the access cell combination corresponding to maximum as mode decision scheme.

Example two:

When many cards multithread terminal includes three LTE module,

If only recording a frequency, the Serving cell being currently accessed the most only detected, then skip this judgement, Do not change current access way；

If recording two frequency bins, when two LTE module access service communities, Tph=T (RSRP1) * (1+G (RSRP))+T (RSRP2), when two LTE module access adjacent cell, Tph= T(RSRP1)+T(RSRP2)*(1+G(RSRP2))；Relatively above-mentioned calculated two Tph values, Choose access cell combination corresponding to maximum as mode decision scheme；

If recording three and above frequency, if the value being only smaller than RSRP2 in adjacent cell is RSRP3, this In the case of in addition to calculating above two and accessing cell combination, also need to calculate three LTE communities and connect respectively Enter anticipated total throughout value during different districts, this Tph=T (RSRP1)+T (RSRP2)+ T (RSRP3), relatively calculated three Tph values, and choose the access cell combination that maximum is corresponding As mode decision scheme.

Example three:

When many cards multithread terminal includes four LTE module,

If only recording a frequency, the Serving cell being currently accessed the most only detected, then skip this judgement, Do not change current access way；

If recording two frequency bins, two LTE module access service communities, other two LTE module connect Enter adjacent cell, corresponding anticipated total throughout value Tph=T (RSRP1) * 1+G (RSRP1))+ T(RSRP2)*1+G(RSRP2))；

If recording three frequencies, in addition to including above-mentioned access cell combination, also include following two group Conjunction mode, when two LTE module access service communities, and other two LTE are respectively connected to different neighbours During community, Tph=T (RSRP1) * (1+G (RSRP1))+T (RSRP2)+T (RSRP3)；When two When individual LTE module accesses same adjacent cell, Tph=T (RSRP1)+T (RSRP2) * (1+ G(RSRP2))+T(RSRP3)；Relatively above-mentioned calculated three Tph values, choose maximum corresponding Access cell combination as mode decision scheme；

If recording four and during above frequency, choosing and being only smaller than the value of RSRP3 is RSRP4, this feelings Under condition, in addition to needs calculate above-mentioned three kinds of modes, also need to calculate when four LTE module are respectively connected to four Anticipated total throughout value during individual different districts, this Tph=T (RSRP1)+T (RSRP2)+ T(RSRP3)+T(RSRP4)；Relatively above-mentioned calculated four Tph values, choose maximum corresponding Access cell combination as mode decision scheme.
