Detailed description of the invention

Should be appreciated that specific embodiment described herein, only in order to explain the present invention, is not used to limit The present invention.

With reference to the schematic flow sheet that Fig. 1, Fig. 1 are inventive network system of selection first embodiment.This enforcement In example, described network selecting method includes:

Step S10, when determining that carrying out network selects, starts web search, and enters the network searched Row sequence, obtains the prioritization result of network；

Step S20, selects optimal network according to described prioritization result.

Heretofore described network specifically refers to mobile communications network, such as 2G network, 3G network, 4G Network.Typically when terminal unit is started shooting or restarts, it is required for carrying out network selection, meanwhile, in terminal After equipment is even connected to the Net, if network quality declines, need too to carry out network selection.

Mainly certain according to network side community selection, gravity treatment and switching is selected currently for network Strategy finally determines, but under normal circumstances mainly according to signal intensity and the native region priority of each community Determine which community is terminal reside in.Such as, for some regions, possible 2G signal 4G very by force Signal is the most weak, and therefore according to current network selection policies, mobile terminal eventually resides in 2G cell, Thus user's experience will be reduced.

In the present embodiment, searched for by opening network and prioritization, improve original network and select Strategy such that it is able to selector closes the optimal network of current practice from prioritization result, and Achieve the Optimum Matching to current network resources, therefore, either carry out network reselection or network Switching, can obtain network optimum under current practice, thus improve user's experience.

With reference to the refinement schematic flow sheet of step S10 in Fig. 2, Fig. 2 Fig. 1.In the present embodiment, above-mentioned step Rapid S10 includes:

Step S101, startup different-frequency measure, to carry out web search, obtains the network of network ginseng searched Number, wherein, described network parameter at least includes network formats, bandwidth, signal intensity；

Step S102, according to the described network parameter of the network searched, searches presetting database to obtain The current ideal rate of the network searched；

Step S103, according to the described network parameter of the network searched, the current reason of network that searches Think speed, the network searched is carried out prioritization, obtain the prioritization of the network searched Result.

After meeting the condition carrying out network selection, mobile terminal device by startup different-frequency measure to carry out Web search.In the present embodiment, multiple for being typically all coated with in current same geographical coverage area The situation of standard (heterogeneous networks frequency range) network, therefore, preferably employs different-frequency measure side in the present embodiment Formula carries out web search, to search for other networks of other Serving cells or adjacent area, and the most high network, Such as 4G network, 3G network etc..Meanwhile, even if being also provided that when low signal ratio is high for high network The low feature waiting the higher network rate of network during signal, therefore, in the present embodiment, the most only searches for High network such that it is able to the speed making the network that searches corresponding is higher than the speed of current network. Certainly, search for high network be a kind of preferably and satisfactory optimal network can be quickly found out Mode, but the present invention is not restricted to only with aforesaid way, it is also possible to the network to all neighbor cells Scan for and sort, or all of network including current network is ranked up.

After completing web search, need each network is ranked up, to form the priority row of network Sequence.In the present embodiment, for obtaining optimal network the most accurately, reduce and avoid due to network excellent First level sequence inaccuracy and the network of most suitable optimum can not be selected, thus be on the one hand likely to result in needs The most frequently carry out repeatedly network to select；On the other hand, owing to not choosing the network of most suitable optimum Thus more preferably business experience can not be provided the user.

Therefore, for improving the sequence accuracy for network priority further, in the present embodiment, pass through Actually used experience is also calculated that obtain, corresponding for weighing heterogeneous networks parameter in actual use The theoretic peak transfer rate ideal rate that can be provided by of network, it more can be as weighing network The important benchmark of quality (such as network rate).It is therefore preferable that the current ideal rate adding network is made Important ranking factor for network priority sequence.

Prioritization is carried out according to the network parameter corresponding to each network obtained, current ideal rate, Thus i.e. can get each network ranking results in priority.The sequence of network priority in the present embodiment Requirement is: high network sorts front with high signal intensity；Low network such as grade and low signal intensity sort rear. But specifically need to arrange the weight order that each network parameter is corresponding, then further according to final integrated ordered Score value determines the prioritization result of network, and concrete prioritization is exemplified below:

Such as, first heterogeneous networks parameter is arranged each self-corresponding calculating weight, such as network formats power Be heavily 2, network frequency range weight be 1, bandwidth weighting be 1, signal intensity be 2, ideal rate weight be 4.

Secondly, then the numerical value that each network parameter is corresponding respectively is arranged corresponding metric, such as, for Network formats, the metric of 4G network is 5, and the metric of 3G network is 4, and the measurement of 2G network Value is 2；In like manner, the metric corresponding to network frequency range, bandwidth, signal intensity difference can be preset, from And ultimately form the computing formula of network priority comprehensive scores sequence:

Network priority comprehensive scores=network formats metric * 2+ network frequency range metric * 1+ network bandwidth Metric * 1+ network signal intensity metric * 2+ network ideal rate metric * 4；

Specifically arranging the most only for illustration of above-mentioned network parameter metric and corresponding score weight It is not intended to limit the present invention.Above by arranging the metric of each parameter and only calculating the mode of weight A simply preferred embodiment of the present embodiment, above-mentioned each network parameter metric and corresponding score weight Setting obtains according to many experiments measuring and calculating, thus the precision of the prioritization result obtained can be higher. In the present embodiment, by choosing different parameters sortnig, the weight of parameters sortnig and calculations, from And obtain the highest network priority ranking results more accurately of accuracy.

Optionally, it is also possible to farther include the sequence to current network with other networks searched.? After adding the prioritization to current network, can more fully overall, to current mobile eventually The prioritization of the all-network that end can connect, and then can draw including current network Optimal network in all-network.This optimal network is likely current network, it is also possible to for searching A certain network.

In view of, in the existing processing mode selecting network, such as cell reselection, community switching, community are stayed Stay strategy etc., do not ensure that the network of selection must be optimum, therefore, also in current all-network The optimal choice to Internet resources cannot be realized and mate, thus have impact on user's experience.This reality Execute in example, it is preferred to use different-frequency measure mode carries out the search of high network, and according to the network searched Parameter, the current ideal rate of network that searches, the network searched is carried out prioritization, It is thus possible to the network priority ranking results more tallied with the actual situation, namely obtain meeting currently practical The optimal network of situation.

Further, with reference to the flow process signal that Fig. 3, Fig. 3 are inventive network system of selection the second embodiment Figure.In the present embodiment, also include before above-mentioned steps S10:

, when there is data service in step S00, it is determined whether carries out network selection.

In the present embodiment, when there is data service on mobile terminal and carry out network selection, typically will choosing The network selected is for carrying out network switching.Before carrying out network switching, need first to carry out network selection, first The condition to whether carrying out network selection is needed to judge and determine, if reaching a certain condition, it is determined that Proceed by network to select.Arrange a lot for this condition, such as, carry out network choosing every Preset Time Select；Or carry out network selection when network speed is less than a certain speed.Typically carry out network selection and realize net The switching of network mainly improves treatment effeciency or processing speed, therefore the present embodiment of network data service In preferably when user uses data service, during the biggest data service (such as Online Video etc.), Need to select to judge to whether carrying out network, thus select more excellent network transmission speed to ensure to use The smooth and easy of the big data service at family is carried out.

When meeting condition and need to carry out network selection, web search now will be started, and to search To network be ranked up, thus obtain the prioritization result of each network searched.Such as, 2G network, 3G network, 4G network, the most under equal conditions, the transmission of 4G network are searched Speed should be the highest, but due to other factors impacts such as distance, interference, accordingly, it would be desirable to the most Plant network parameter and carry out the comparison of priority, and obtain the priority arrangement of each network sequentially, finally select Optimal network in ranking results.Such as, if current network is 3G network, and the Network Priority after sorting Level order is 4G > 2G > 3G, then optimal network is 4G network, and then again by current 3G network switching To optimum 4G network.

Further, with reference to Fig. 4-5, Fig. 4 is the refinement flow process signal of an embodiment of step S00 in Fig. 3 Figure；Fig. 5 is the refinement schematic flow sheet of another embodiment of step S00 in Fig. 3.In the present embodiment, Above-mentioned steps S00 specifically includes two classes for whether carrying out the Rule of judgment of network selection:

One class is, when data service starts, by judging that whether the ideal rate of current network is less than pre- If speed carries out the judgement of network selection；

Another kind of, during data service is carried out, by judging the actual speed rate of current network and working as Whether the ratio of the ideal rate of front network is less than default ratio carries out the judgement of network selection.

Above-mentioned two class conditions corresponding respectively concrete judge that step includes:

Embodiment 1: when data service starts, carries out the judgement of network selection；

Step S011, when data service starts, obtains the described network parameter of current network；

Step S012, according to the described network parameter of the current network got, search presetting database with Obtain the ideal rate of current network；

Step S013, it is judged that whether the ideal rate of current network is less than scheduled rate；

Step S014, if, it is determined that carry out network selection.

When detecting that user just begins to use data service, mobile terminal the most also can not be instantly available The actual speed rate of currently used network, therefore, under this type of sight, it may be judged whether carry out network selection Condition be preferably arranged to: judge that the ideal rate of current network is whether less than scheduled rate.

In the present invention, the ideal rate of network refers to the different systems drawn according to practical experience, different letter Theoretical Rate value when number intensity, such as: under LTE FDD network 20M bandwidth, Cat4 terminal, Excellent network signal intensity (as >-85dbm) under corresponding to ideal rate be Theoretical Rate 150M's 90%, i.e. 135M；Secondary excellent network signal intensity (such as-88dbm >=RSRP >=-95dbm), lower right The ideal rate answered is Theoretical Rate 80%, i.e. 120M.Wherein, RSRP represents that reference signal receives merit Rate.Under above-mentioned heterogeneous networks parameter, the concrete percentage when signal intensity corresponding to different theories speed is drawn Point need to be confirmed by specific experiment debugging, the classification of above-mentioned ideal rate include but not limited to various standard, The assembled classification of various bandwidth, various cat terminal, various signal intensitys etc..

In the present embodiment, by heterogeneous networks parameter, as strong in network formats, network frequency range, bandwidth, signal Network ideal rate corresponding to degree etc. stores and in presetting database, by the current network parameter obtained Search and mate network parameter corresponding in presetting database, current network ideal rate can be obtained. Additionally, for ensureing either can carry out under 2G network or 3G network at selection and the switching of network Reason, thus finally make user can obtain more excellent data service under various networks and experience, this enforcement Scheduled rate is preferably set as 2M by example, namely defines at 2G network, 3G network, 4G network Deng under all-network standard, as long as meeting the Rule of judgment that above-mentioned network selects: the ideal of current network Whether speed, less than scheduled rate 2M, i.e. determines and needs to carry out network selection.

Embodiment 2: during data service is carried out, carries out the judgement of network selection；

Step S021, during data service is carried out, obtains the described network parameter of current network and works as The actual speed rate of front network；

Step S022, according to the described network parameter of the current network got, search presetting database with Obtain the ideal rate of current network；

Step S023, it is judged that whether the ratio of the actual speed rate of current network and the ideal rate of current network Less than presetting ratio；

Step S024, if, it is determined that carry out network selection.

When detecting that user uses in data service procedures, now by data service data upload with Download situation, can obtain the actual speed rate of current network.By network formats, network frequency range, bandwidth, Signal intensity network parameter can obtain the ideal rate of current network, if the actual speed rate of current network with The ratio of the ideal rate of current network is less than presetting ratio, then the selection carrying out network processes.This enforcement In example, the setting presetting ratio can set according to actual needs, such as, be set as 60%, namely work as network The ratio of ideal rate of actual speed rate and network less than 60% time, i.e. determine and need to carry out network selection.

Mobile terminal device that the Theoretical Rate of general networking can be used by user, network equipment, transmission The impact of the many factors such as distance, base station disposal ability, network peak period, signal attenuation, therefore net The actual speed rate of network is less than Theoretical Rate, in the present invention propose ideal rate be then rule of thumb and Experiment measuring and calculating obtains, and can realize, namely can regard as in actual use, no Can the corresponding iptimum speed realized with network parameter.In the present invention, the actual speed rate of general networking is less than Or the ideal rate (iptimum speed that can reach) equal to network, the ideal rate of network is then less than The Theoretical Rate (being difficult to time actually used reach) of network.

Further, for more preferably realizing sentencing of the ideal rate for the network corresponding to current network parameter Break, namely realize the assessment of the optimal rate that current network be can be provided by, optionally, when getting net During the actual speed rate of network, carry out the judgement that the Theoretical Rate of network updates.If meeting pre-conditioned, then will The actual speed rate of the network obtained is updated to network parameter corresponding to this actual speed rate institute in presetting database Corresponding ideal rate.Such as, under mobile terminal is practically in a certain network such as 20M bandwidth, Cat4 Terminal, excellent network signal intensity (as >-85dbm) time, actual speed rate is 134, belongs to ideal rate Scope (as set the ideal rate scope corresponding to this network parameter as 120-140M), then according to work as Front actual speed rate, updates ideal rate value corresponding to identical network parameter in presetting database, if being not belonging to Above-mentioned set point, does not updates.

Above-described embodiment is the most preferred embodiment that the present invention triggers the Rule of judgment carrying out network selection.For It is a lot of that triggering carries out being provided with of the Rule of judgment of network selection, such as, when user uses data service, Automatically trigger every Preset Time；Or when the rate of change of the actual speed rate of network is fast more than presetting change Automatically trigger during rate.Therefore, do not do and too much repeat explanation.

Further, with reference to the flow process signal that Fig. 6, Fig. 6 are inventive network system of selection the 3rd embodiment Figure.In the present embodiment, also include after above-mentioned steps S20:

Step S30, is switched to described optimal network by current network.

Network switching refers to the network in current mobile terminal is switched to other networks, including heterogeneous networks Switching between standard (network hierarchy), and identical network standard (network hierarchy), different service are little The network switching in district.Such as it is switched to 4G network from current 3G network；Or from current service cell 3G network be switched to the 3G network of neighbour cell.

In the present embodiment, by optimal network current network being switched in network priority ranking results, It is thus possible to improve the quality of current network further, promote the experience of user.

Further, with reference to the refinement schematic flow sheet that Fig. 7, Fig. 7 are step S30 in Fig. 6.This enforcement In example, step S30 includes:

Step S301, obtains the network handoff parameter that current network is the most corresponding with described optimal network；

Step S302, according to predesigned compensation value, cuts the network of current network with described optimal network respectively Change parameter and carry out virtual compensation deals；

Step S303, on the network handoff parameter with described optimal network of the current network after compensating respectively Report network side is to realize the current network network switching to described optimal network.

In view of current network side is for selection, gravity treatment and the switchover policy of network cell, and above-mentioned reality Execute ordering requirements and the mode of network priority in example, in the prioritization result in above-described embodiment Optimal network not necessarily meets the network switchover policy of network side, therefore, wants to realize current Network is switched to optimal network, in addition it is also necessary to process the handoff procedure of network, thus is meeting network On the premise of side requires for network switchover policy, promote and realize cutting from current network to optimal network Change.Such as by virtual compensation deals, with from numerically changing the current value of network handoff parameter, from And can promote that current network arrives the network switching of described optimal network.In the present embodiment, corresponding network Handoff parameter is a lot, and such as, (Reference Signal Receiving Power, reference signal connects RSRP Receive power), RSRQ (Reference Signal Receiving Quality, Reference Signal Received Quality) etc.. When community selection or gravity treatment, both can only measure RSRP, it is also possible to composite measurement also compares RSRP With RSRQ, being illustrated with measurement RSRP in detail below, specific implementation is as follows:

First, the network handoff parameter that current network is the most corresponding with described optimal network is obtained；Such as, Terminal measures for current cell signal strength RSRP, and obtaining measurement result is M, meanwhile, right In being measured by the optimal network RSRP selected by prioritization, obtaining measurement result is N. Secondly, according to predesigned compensation value, respectively the network handoff parameter of current network Yu optimal network is carried out void Intend compensation deals；Such as, the RSRP of current area is carried out negative compensation, and obtains carrying out negative compensation After RSRP value M_Newly, namely M_Newly=M-P_Low, wherein, P_LowFor default negative offset；The most also The RSRP of optimal network is just compensated, and obtains RSRP value N after just compensating_Newly, also I.e. N_Newly=N+P_High, wherein P_HighFor default positive offset.By virtual negative compensation deals, thus reduce The signal intensity of current area, and by virtual positive compensation deals, thus it is right to improve optimal network institute Answer the signal intensity of community, finally by M_NewlyWith N_NewlyReport network side, thus network side is according to terminal to report The measurement result of RSRP and adjudicate and be switched to optimal network from current network, terminal is receiving network Can complete and realize after the judgement of side to be switched to optimal network from current network.

Owing to changing the ordering rule of legacy network priority, therefore, the net corresponding to current network side Network switchover policy might not be capable of the automatic switchover from current network to optimal network, therefore, originally Embodiment promotes that by the way of using virtual compensation cell signal strength the network switching of network side is sentenced Determine, thus promote that network side makes the judgement of the automatic switchover from current network to optimal network, Jin Ershi Existing current network is to the automatic switchover of optimal network, it is ensured that the present embodiment can be correctly completed from current net Network is to the automatic switchover of selected optimal network.

Further, with reference to the flow process signal that Fig. 8, Fig. 8 are inventive network system of selection the 4th embodiment Figure.In the present embodiment, also include after step S30:

Step S40, after being switched to described optimal network, it is judged that the currently practical speed of described optimal network The actual speed rate of the network corresponding to the most front more than switching；

Step S50, the most then continue to reside in described optimal network；

Step S60, if it is not, then switch back into the front corresponding network of switching or be switched to described priority row Suboptimal networks in sequence result.

In above-mentioned preferred embodiment, in the feelings not having addition that the priority of current network is ranked up Under condition, although in most of the cases, the speed of the optimal network (the most high network) after switching Will be higher than the speed before switching, but this does not represent other network transmission speeds searched and is higher than The transfer rate of the network being being currently used, therefore, is switched to search from current network completing Optimal network switching after, in addition it is also necessary to further determine the currently practical of the optimal network after switching The actual speed rate of the network corresponding to speed is the most front more than switching, the most then continue to reside in optimum net Network；If it is not, the most again switch over.

Such as, currently used network is 2G network, but the current network transmission speed of this 2G network is very Slowly, therefore, start the networks (4G, 3G) such as searching neighboring area height and sort, if ranking results is 4G being Optimal network, 3G network suboptimum, then current 2G network is switched to 4G network, meanwhile, complete After becoming network switching, compare the reality of the 2G network before the actual speed rate of the 4G network after switching and switching Border speed, if the actual speed rate of 4G network is more than the actual speed rate of 2G network, it is determined that 4G network is more Excellent, namely continue to reside in the 4G network of optimum.And if the actual speed rate of the 4G network after switching is less than The actual speed rate of the 2G network before switching, then switch back into the 2G network before switching by 4G network.Additionally, The actual speed rate of the network after judging switching needs again to enter less than the actual speed rate of the network before switching During the switching of row network, it is also possible to be switched to suboptimum 3G network.In the present embodiment, for the priority of network Sequence combines multiple parameters and draws, therefore, even if in priority, and optimal network preferential Level is higher than suboptimal networks, but the actual speed rate corresponding to optimal network might not be greater than suboptimal networks Actual speed rate.

Further alternative, after being switched to suboptimal networks, in addition it is also necessary to reaffirm the network before switching Whether actual speed rate is more than the actual speed rate of the suboptimal networks after switching.

Preferably, need to carry out the switching of network due to the impact of interference factor for getting rid of, therefore, also Can further complete network switching after Preset Time, the optimal network after switching over work as The comparison of the actual speed rate of front actual speed rate corresponding network front with switching.If the optimal network after Qie Huan Currently practical speed more than the actual speed rate of network corresponding before switching, then continue to reside in optimum net Network；If the currently practical speed of the optimal network after Qie Huan is less than the actual speed of network corresponding before switching Rate, then switch back into the front corresponding network of switching or be switched to the suboptimum in described prioritization result Network.

For example, it may be possible to cause the provisional decline of current network speed during due to network peak period, wait peak Phase one terminates, current network speed can return to again before preferably speed, therefore, peak period need Optimal network to be switched to, and etc. peak period terminate, then the speed of the optimal network after switching over cut The comparison of the speed of the network before changing.

It is further preferred that after continuing to reside in optimal network, corresponding network before switching is added Enter default blacklist to control network corresponding before being no longer switched to this switching within the setting time；Or, Network corresponding to before returning switching or after being switched to the suboptimal networks in prioritization result, Optimal network is added and presets blacklist to control no longer to be switched to this optimal network within the setting time.

In the present embodiment, for avoiding the most invalid network to switch, when the reality of the optimal network after switching When speed is more than the actual speed rate of the network before switching, while continuing to reside in optimal network, will cut Before the default blacklist of network addition corresponding before changing is to control no longer to be switched to this switching within the setting time Corresponding network.And the reality of the network before the actual speed rate of the optimal network after switching is less than switching During speed, network corresponding before returning switching or the suboptimum net being switched in prioritization result While network, optimal network is added and presets blacklist to control no longer to be switched within the setting time this Excellent network.For the control of the scheduled time, can be controlled by the way of timer, such as, when When adding network in default blacklist, timer starts timing and when the time reaches the scheduled time, clearly Except the Network records in this default blacklist.

Do not include currently owing to high network preferably being scanned for by above-described embodiment and sort The comparison of the actual speed rate of network, therefore, after the present embodiment need nonetheless remain for switch over further The actual speed rate of excellent network compares with the actual speed rate of the network before switching, namely the network of confirmation terminal is No resident optimal network community after handover.Own by further confirming that more fully to compare Network, thus select more suitably optimum network；Or other influences factor can be got rid of further Affect and choose optimal network, thus bring the optimum experience of data service to user.
