The necessity for how switching SIM card according to base-station environment condition judgment has been shown in particular in the present embodiment.Here
Base-station environment condition can include can by base station signal coverage, whether base station network abnormal, base station service can be by
Normal offer etc..Herein, whether base station network can be determined as follows extremely：If base station signal is weaker than a certain threshold
It is worth, and/or has base station signal but without base station network, be then believed that base station network is abnormal.The embodiment of the present invention is according to the base station
Environmental condition determines whether there is abnormal base station, optionally, it is determined whether abnormal base station be present includes two aspects：First, consider each
The signal cover of base station, for current location, if the base station that signal can cover current location be present, if not
The base station that signal can cover current location be present, then it is believed that presence can not provide the abnormal base station of base station service；Second,
In the case where presence can cover the base station of current location, whether determine whether the base station is different extremely according to base station network
Chang Jizhan, if base station network is abnormal, it is determined that the base station is abnormal base station.Can be true according to base-station environment condition by the above method
Fixed existing abnormal collection of base stations, then reject abnormal collection of base stations from default map data base, remaining collection of base stations
Then it is considered normal Base Station set.
In some optional embodiments, it is determined whether normal Base Station be present can also be in the following way.First, consider
The signal cover of each base station, for current location, if the base station that signal can cover current location be present, if
The base station that signal can cover current location be present, then it is believed that the normal Base Station for providing base station service be present.Second, depositing
In the case where the base station of current location can be covered, whether determine whether the base station is abnormal base extremely according to base station network
Stand, if base station network is normal, it is determined that the base station is normal Base Station.
Current translational speed can be calculated by the geographical location information got.Certainly it is not that explanation is moved here
Dynamic equipment must configure power plant module, but can be calculated according to the scene (such as on train) that it is placed.Citing and
Speech, within a period of time (such as 3s), current geographic position information several times is obtained by GPS module, according to the geography of acquisition
Positional information calculation goes out present speed, can be specifically calculated by the method for differential, or according to Doppler's frequency
Shift-in row calculates, and similar mathematical method has a lot, is not limited herein.When GPS module can export NMEA0183 agreements
During message, it can even more be directly read from message to present speed.
According to current geographic position information, present speed, default route information and (current SIM of default switching time
After card switches to another SIM card, data communication module identifies the SIM card after the switching, dialing establishes connections to recovery number again
A period of time is needed according to communication, this time is referred to alternatively as switching time, usually 20s or so) it can calculate in switching time
Geographical location information during arrival, this point are very simple.So this geographical location information calculated is by searching ground
Chart database (is referred to the map data base in previous embodiment), it may be determined that its coverage in which base station
It is interior.So according to the state of each base station, a normal Base Station set (being also likely to be empty set) is can be obtained by naturally.Citing and
Speech, currently used SIM card is UNICOM's SIM card, and the base station in normal Base Station set is moved, belonging to telecommunications respectively, then such as
Mobile SIM card is provided with the fruit mobile device, is exactly now the necessity for switching SIM card.If empty set, then just do not have
Switch necessity of SIM card.If multiple SIM cards can switch, one can be chosen at random or according to priority.
In the above embodiments, base station information is included in map data base, in one embodiment of the invention, is provided
The maintaining method of base station information, the i.e. above method also include：The duration that Network Abnormal state is in when SIM card reaches pre-
When fixing time, current geographic position information is obtained, the base station that SIM card is currently accessed is found out from map data base, by the base
The status indication stood is abnormality；Abnormality is reported into server, so that server receives in preset time period
It is abnormal base station by the basestation marker when reporting the number to reach predetermined threshold value to the abnormality.
Map data base is referred in previous embodiment to be updated, and, can receive clothes with reference to the present embodiment specifically
The base station information that business device issues, or, base station information regularly is asked from server, according in base station information updating map data base
The state of each base station.It (can be specifically, in mobile device energy that server, which can receive the abnormality that mobile device reports,
When enough networking), if in predetermined amount of time, there is the abnormality that multiple mobile devices have reported a certain base station, then just should
Basestation marker is abnormal base station.It is contemplated that the active push base station information or by mobile device when base station state changes
Active obtaining base station information.In view of the maintenance efficiency of base station, server can also be within a period of time actively by abnormal base station
The mark of normal Base Station is reverted to, if receiving the abnormality for reporting the base station again, then is meeting bar according to preceding method
The mark processing of abnormal base station is re-started during part.
In one embodiment of the invention, in the above method, environmental condition is terrain environment condition, according to default ring
The necessity whether border condition judgment has switching SIM card includes：According to the current geographic position information of acquisition, from default map number
According to finding out corresponding terrain environment information in storehouse；When landform environmental information instruction terrain environment condition is Network Abnormal landform
When, it is judged as not switching necessity of SIM card, is otherwise judged as there is necessity of switching SIM card.The Network Abnormal landform can be with
It is that base station network easily occur abnormal and/or can not provide the geographical environment of normal Base Station service, such as mountain valley, tunnel, difference
Network operator services overlapping region etc..
In this case Network Abnormal landform, such as mountain valley, tunnel etc. can be identified in map data base.Here with showing
The advantage for having technology to compare also resides in：Because prior art is after mobile device enters Network Abnormal landform, SIM can be constantly carried out
Card switching, and the SIM card of a Network Abnormal state when mobile device leaves the Network Abnormal landform, may be just switched to,
Now also need to be switched to another SIM card；And in the present embodiment, if original SIM when mobile device leaves the Network Abnormal landform
Card network state recovers normal, then need not carry out SIM card switching.Therefore it is (i.e. foregoing 20s or so can be saved under optimal cases
The switching time that embodiment is previously mentioned) time.
In one embodiment of the invention, in the above method, each SIM card is set with priority respectively, and this method is also
Including：According to the current geographic position information of acquisition, the base station for being currently able to access is found out from default map data base；
According to the base station for being currently able to access and the priority of each SIM card, determine whether to switch necessity of SIM card.
In many cases, although user inserts multiple SIM cards in a mobile device, it is more desirable to use therein one
.Can be now that each SIM card sets priority, such as certain user wishes mainly to use a telecommunications SIM card, by UNICOM SIM
Card from charging angle as standby (such as considering, only for example).In this case, if mobile device exists in telecommunications SIM card
After being switched to UNICOM's SIM card, if it is determined that the coverage of telecomm base station has been currently entering, although at this moment may UNICOM SIM
The network state of card is also very good, but can switch back into telecommunications SIM card again.The demand being thus more close to the users.
The switching method of the SIM card shown in the various embodiments described above can be separately from can also enter according to the actual requirements
The certain combination of row, the present invention are without limitation.
Exemplary explanation is carried out with reference to a concrete scene：A 4G routers, 4G routes are deployed with certain train
UNICOM's SIM card and a movement SIM card are provided with device, and gives tacit consent to connection UNICOM SIM card, wherein, 4G routers are additionally provided with ground
Chart database, for storing the base station letters the such as whether geographical location information of base station, coverage, operator, state abnormal
Breath.
In train driving, easily there are following situations：
1) when the Network Abnormal landform such as train driving to tunnel, mountain valley, it may appear that the situation of network state extreme difference.If
According to prior art, 4G routers are easy to trigger SIM card switching condition, and UNICOM's SIM card is switched into mobile SIM card, but aobvious
So this switching is insignificant, and the mobile SIM card after switching is similarly in the network state of extreme difference, again can be by mobile SIM card
UNICOM's SIM card is switched back into, so repeatedly until leaving Network Abnormal landform.Therefore according to technical side provided in an embodiment of the present invention
Case, in full triggering SIM card switching condition, determined whether to switch necessity of SIM card according to landform environmental condition, in this scene
Under, it is clear that can be judged as belonging to Network Abnormal landform, then just do not perform SIM card switching, the judgement can perform always until
Train leaves Network Abnormal landform.4G modules very first time trial can recover former network environment after Network Abnormal landform is left.
If according to switching flow of the prior art, when leaving Network Abnormal landform, a SIM card switching may be just triggered,
The technical scheme of the embodiment of the present invention can at most save switching time T.
2) when triggering SIM card switching condition, the SIM card after switching can also be judged (in this example for mobile SIM card)
A normal Base Station can be accessed after switching time T.By taking T=20s as an example, if performing SIM card switching according to prior art,
The position that 20s rank rears garage sails to does not have mobile base station covering, then and the same network of mobile SIM card after switching is obstructed, according to
So meet SIM card switching condition, then this is once insignificant switching again, therefore in an embodiment of the present invention, can be sentenced
Whether the position that disconnected 20s rank rears garage sails to has the mobile base station covering that can normally provide service, is not performed if not
SIM card switches, and at most can also save switching time T.
It is above-mentioned 1) to be performed parallel with 2) the middle judgement performed, a preferential execution can also be selected.
1) and 2) if pointing out to switch necessity of SIM card according to the judged result in, SIM card switching can be performed,
UNICOM's SIM card is so switched to mobile SIM card again.If mobile SIM card still network is obstructed, then thinks now to move
The base station state of SIM card access is abnormal, can record the abnormality of the base station, server is reported in network recovery.This
When 1) and 2) can also repeat in judgement, whether see needs to switch back into UNICOM's SIM card.
