The present invention further provides a kind of method for switching network.

With reference to the schematic flow sheet that Fig. 6, Fig. 6 are inventive network changing method first embodiment, first In embodiment, this method for switching network comprises the following steps:

Step S10, the signal intensity of the first standard network that detection mobile terminal is currently used, wherein, when First standard network of front use is current in the multiple types network that mobile terminal activating eSIM card is corresponding The standard network being selected；

In the present embodiment, being prefixed many set eSIM cards in mobile terminal, wherein, often set eSIM card all has ESIM_ID and HPLMN, this HPLMN that have correspondence often overlap, for labelling, the operation that eSIM card is corresponding Business.Such as, if mobile terminal is prefixed eSIM1 card, eSIM2 card and eSIM3 card, wherein, eSIM1 The HPLMN that card is corresponding is 46003, and the HPLMN that eSIM2 card is corresponding is 46000, and eSIM3 card is right The HPLMN answered is 46001, then the operator that eSIM1 card is corresponding is China Telecom, corresponding China electricity The standard networks such as LTE, CDMA, EVDO that letter is comprised；During the operator that eSIM2 card is corresponding is The standard networks such as state moves, LTE, TDSCDMA, GSM that corresponding China Mobile is comprised；eSIM3 The operator that card is corresponding is CHINAUNICOM, LTE, WCDMA, GSM that corresponding CHINAUNICOM is comprised Etc. standard network.Mobile terminal in use, arranges a set of eSIM card therein in many set eSIM cards For activating eSIM card, as the eSIM card that mobile terminal is currently used, other eSIM card is for deactivating ESIM card alive.Such as, arranging eSIM1 card is to activate eSIM card, and eSIM2 card and eSIM3 card are for going Activate eSIM card.Further, from the multiple types network activating eSIM card correspondence, a standard net is chosen Network is the first standard network that mobile terminal is currently used, namely the first standard that mobile terminal is currently used Network is the standard network being selected in the multiple types network that mobile terminal activating eSIM card is corresponding.Moving When dynamic terminal uses this first standard network work, detect the first currently used standard net in real time or regularly The signal intensity of network.

Step S20, the signal intensity at currently used described first standard network is less than described first standard During the first preset signal strength threshold value corresponding to network, each eSIM card correspondence of detection mobile terminal is extremely The signal intensity of a few second standard network；

In the present embodiment, pre-set every kind of preset signal strength threshold value corresponding to standard network, such as, The preset signal strength threshold value pre-setting the first currently used standard network corresponding is the first preset signals Intensity threshold C₁.When the signal intensity of the first currently used standard network being detected, mobile terminal ratio The signal intensity of the first currently used standard network relatively detected and the first preset signal strength threshold value C₁'s Size, the signal intensity at the first currently used standard network of detection is less than the first preset signal strength Threshold value C₁Time, namely illustrate that, when the signal of the first currently used standard network is the best, mobile terminal detects The signal intensity of at least one the second standard network that each eSIM card is corresponding.Right owing to often overlapping eSIM card The standard network answered is different, overlaps eSIM accordingly, it is possible to activate to have in eSIM card and deexcitation eSIM card more Block corresponding second standard network, it is also possible to the only corresponding second standard network of a set of eSIM card.Such as, exist In above-mentioned row illustrated example, if the second standard network is LTE, then eSIM1 card, eSIM2 card and eSIM3 A card corresponding second standard network respectively；If the second standard network is WCDMA, the most only eSIM3 The corresponding second standard network of card.

Signal intensity at the first currently used standard network of detection is more than or equal to the first preset signals Intensity threshold C₁Time, namely illustrate that the signal of the first currently used standard network is good, now, mobile whole End continues to use the first currently used standard network to communicate.

Step S30, have the signal intensity of the second standard network corresponding more than described second standard network the During two preset signal strength threshold values, determine whether the eSIM card that described second standard network is corresponding is activation ESIM card；

Step S40 is when the eSIM card that described second standard network is corresponding is not to activate eSIM card, right The eSIM that described second standard network is corresponding sticks into line activating operation, carries out deexcitation to activating eSIM card Operation, switches to described second standard network by the first currently used for mobile terminal standard network.

When detect at least one the second standard network signal intensity after, compare detection at least one second The second preset signal strength threshold value C that the signal intensity of standard network is corresponding with this second standard network₂Big Little.When having the signal intensity of the second standard network more than the second preset signal strength threshold value C₂Time, mobile whole End determines whether the eSIM card that this second standard network is corresponding is to activate eSIM card.

When eSIM card corresponding to this second standard network is just for mobile terminal activating eSIM card, the most not Needing to carry out the switching of eSIM card, the first currently used standard network is directly switched to activation by mobile terminal The second standard network that eSIM card is corresponding.The eSIM card corresponding when this second standard network be not whole for moving When end activates eSIM card, mobile terminal performs eSIM card handover operation, and this second standard network is corresponding ESIM stick into line activating operation, eSIM card the currently active to mobile terminal carries out deactivating operation simultaneously, The first currently used for mobile terminal standard network is switched to the second standard network.Afterwards, mobile terminal The second standard network is used to communicate.

Below with activation eSIM card for eSIM1 card, deexcitation eSIM card includes eSIM2 card and eSIM3 Card, currently used the first standard network of mobile terminal is CDMA, as a example by the second standard network is LTE, Inventive network changing method is described in detail.

Mobile terminal is in real time or timing detects the signal intensity of currently used CDMA, when detect The signal intensity of CDMA is less than the first preset signal strength threshold value C₁Time, mobile terminal detection eSIM1 The signal intensity of LTE of card correspondence, the signal intensity of LTE of eSIM2 card correspondence, eSIM3 card are corresponding The signal intensity of LTE.If the signal intensity of the LTE that eSIM3 card is corresponding is strong more than the second preset signals Degree threshold value C₂, now, mobile terminal determines whether eSIM3 card is to activate eSIM card.Due to eSIM3 Card is deexcitation eSIM card, and mobile terminal performs eSIM card handover operation, eSIM3 is sticked into line activating Operation, carries out deactivating operation to eSIM1 card simultaneously, by CDMA switching currently used for mobile terminal For the LTE that eSIM3 card is corresponding.

The scheme that the present embodiment proposes, when the signal intensity of currently used the first standard network of mobile terminal During less than the first preset signal strength threshold value, namely the signal of the first standard network is the best, now, mobile Terminal detects the signal intensity of the second standard network corresponding to each eSIM card, when there is the second standard network Signal intensity more than the second preset signal strength threshold value time, mobile terminal determines this second standard network pair Whether the eSIM card answered is to activate eSIM card, is not sharp at the eSIM card that this second standard network is corresponding During eSIM card alive, mobile terminal sticks into line activating operation to the eSIM that this second standard network is corresponding, right Activate eSIM card and carry out deactivating operation, the first currently used for mobile terminal standard network is switched to this Second standard network, eliminates user and selects eSIM card and select the standard network that this eSIM card is corresponding Operation, thus improve switching standard network efficiency.

In the present embodiment, the activation eSIM card pre-setting mobile terminal is corresponding with deexcitation eSIM card The priority of each standard network, such as, be followed successively by descending order according to priority: LTE>WCDMA>TDSCDMA>EVDO>GSM.At the first standard net that mobile terminal is currently used The first preset signal strength threshold value C that the signal intensity of network is corresponding less than the first standard network₁Time, mobile whole End is according to the priority of each standard network preset, from each of each eSIM card correspondence of mobile terminal Choosing the second standard network in standard network, the priority of the second standard network chosen is unselected higher than other The priority of each standard network taken, namely from the activation eSIM card of mobile terminal and deexcitation eSIM Each standard network that card is corresponding chooses the second standard network that priority is the highest.Such as, at above-mentioned row For standard network priority sequence example in, priority is followed successively by descending order: LTE > WCDMA > TDSCDMA > EVDO > GSM, when the first standard net that mobile terminal is currently used The signal intensity of network is less than the first preset signal strength threshold value C₁Time, then from the activation eSIM of mobile terminal Block in each standard network corresponding with deexcitation eSIM card and choose the LTE that priority is the highest.

After have chosen the second standard network, the signal intensity of the second standard network that detection is chosen.Such as, If the second standard network chosen is LTE, due to eSIM1 card, eSIM2 card and eSIM3 card respectively A corresponding LTE, then mobile terminal detects the signal intensity of LTE corresponding to eSIM1 card, eSIM2 respectively Block the signal intensity of the LTE of the signal intensity of LTE of correspondence, eSIM3 card correspondence.If choose second Standard network is WCDMA, due to the corresponding WCDMA of only eSIM3 card, then and mobile terminal detection eSIM3 The signal intensity of the WCDMA that card is corresponding.

Further, in the present embodiment, when detecting that signal intensity is more than described second preset signal strength When second standard network of threshold value is multiple, described step S30 includes:

The signal intensity of step a, relatively multiple described second standard networks, choose that signal intensity is maximum the Two standard networks；

Step b, determines whether the eSIM card that the described second standard network chosen is corresponding is to activate eSIM Card.

When mobile terminal detects that the signal intensity of multiple second standard network is more than the second standard network pair The second preset signal strength threshold value C answered₂Time, mobile terminal is by strong for the signal of these multiple second standard networks Degree compares, and therefrom chooses the second standard network that signal intensity is maximum.Afterwards, mobile terminal Determine whether the eSIM card that this second standard network chosen is corresponding is to activate eSIM card, should when choose When eSIM card corresponding to the second standard network is just for mobile terminal activating eSIM card, then it is made without ESIM card switches, and the first currently used standard network is directly switched to activation eSIM card by mobile terminal The second corresponding standard network.When the eSIM card that this second standard network chosen is corresponding is not mobile terminal When activating eSIM card, then mobile terminal performs eSIM card handover operation, this second standard net that will choose The eSIM that network is corresponding sticks into line activating operation, mobile terminal activating eSIM card is carried out deexcitation behaviour simultaneously Make, the first currently used for mobile terminal standard network is switched to the second standard network chosen.

Such as, still in first embodiment as a example by row illustrated example, mobile terminal activating eSIM card is eSIM1 Card, deexcitation eSIM card includes eSIM2 card and eSIM3 card, the first system that mobile terminal is currently used Each standard network that formula network is CDMA, eSIM1 card, eSIM2 card is corresponding with eSIM3 card is pressed excellent First level sorts from high to low and is followed successively by: LTE > WCDMA > TDSCDMA > EVDO > GSM, works as movement The signal intensity of the CDMA that terminal is currently used is less than the first preset signal strength threshold value C₁Time, mobile whole End chooses the LTE that priority is the highest, the respectively signal intensity of LTE of detection eSIM1 card correspondence, eSIM2 Block the signal intensity of the LTE of the signal intensity of LTE of correspondence, eSIM3 card correspondence.If LTE is corresponding Second preset signal strength threshold value C₂For-80dBm, when signal LTE that eSIM1 card is corresponding being detected Intensity be the signal intensity of the LTE that-70dBm, eSIM2 card is corresponding be-49dBm, eSIM3 card correspondence When the signal intensity of LTE is-90dBm, by comparing the signal intensity and second of each LTE detected Preset signal strength threshold value C₂Size understand, the signal intensity of LTE of eSIM1 card correspondence and eSIM2 The signal intensity of the LTE that card is corresponding is more than the second preset signal strength threshold value C₂, now, compare eSIM1 The signal intensity of the LTE that the signal intensity of the LTE that card is corresponding is corresponding with eSIM2 card, chooses wherein signal The LTE that intensity is big, namely choose the LTE that eSIM2 card is corresponding, then judge whether eSIM2 card is sharp ESIM card alive, owing to eSIM2 card is deexcitation eSIM card, eSIM2 is sticked into line activating by mobile terminal Operation, carries out deactivating operation by eSIM1 card, by right for eSIM1 card currently used for mobile terminal simultaneously The CDMA answered switches to the LTE that eSIM2 card is corresponding.

The scheme that the present embodiment proposes, each standard network settings of each eSIM card correspondence of mobile terminal Corresponding priority, when the signal intensity of the currently used first standard network of mobile terminal is low, moves Dynamic terminal detects the second standard network that each standard network medium priority corresponding to each eSIM card is the highest Signal intensity, owing to priority can be arranged flexibly, namely the second standard network can according to user's request with Shi Genggai, thus enrich the switching mode of standard network.
