Specific embodiment
Existing terminal can automatic identification SIM type, but cannot be distinguished by the service condition of each card, therefore similar
Card in cannot accurately select set main card, cause puzzlement to user.In embodiments of the present invention, pass through
Automatic identification user Card Type and judge the professional ability of subscriber card, can preferentially set that standard is senior and business
The stronger subscriber card of ability is used as main card, it is ensured that terminal normal work, enhances Consumer's Experience.
Embodiment one
As shown in figure 1, in one embodiment of the present of invention, the method for automatically selecting terminal main card includes：
S1：User's card information of insertion is read, type and quantity to the subscriber card are identified；
S2：When newest standard subscriber card is more than one, every newest standard subscriber card is selected one by one, judge
The selected support situation blocked to IP multimedia service, and result of determination is marked；
S3：When the newest standard subscriber card of only one support IP multimedia service is labeled, by the branch
The newest standard subscriber card for holding IP multimedia service is set to main card.
Further, in the above-mentioned methods, if the newest standard subscriber card recognized in step S1 is only one,
The card is directly then set to main card.If without newest standard subscriber card, (i.e. whole subscriber cards are GSM systems
Formula standard SIM card) or be marked as supporting IP multimedia service and or having without newest standard subscriber card
More than two newest standard subscriber cards are marked as support IP multimedia service, then by user interface (such as
Into user selection interface or ejection user's selection menu etc.), the main card for directly receiving user is set.Certainly
Can not be selected by user and main card is arbitrarily set, but which is likely to result in the tired of user in some cases
Disturb, only as the alternative of the embodiment of the present invention.
Wherein, newest standard subscriber card refers to the communication that the card is used for other cards of insertion
Standard is more senior, is set to the highest priority of main card.Such as relative to the GSM of 2G standards,
The 3G standards such as TD-SCDMA, WCDMA, CDMA2000 are more senior, therefore 3G standard priority
Higher than 2G standards；Relative to 3G standards, the 4G standards such as TD-LTE, FDD-LTE are more senior, therefore
4G standards priority is higher than 3G standards；And for the mobile communication standard of the same generation, it is generally recognized that its is preferential
Level is identical.But for some contract machines, it is also possible to which the priority of contract standard is suitably heightened, so as to
The preferential subscriber card using contract standard is used as main card on contract machine；Such as in mobile 4G contract machines, can
It is set in advance as the highest priority of TD-LTE standards.
Additionally, judging that certain subscriber card depends on IP multimedias to the support situation of IP multimedia service
Subsystem (IMS, IP Multimedia Subsystem) registration scenarios, the decision process is preferably：First
Mobile communication standard according to selected card carries out the registration of correspondence standard network, then carries out IMS registration,
Whether block according to selected by IMS registration result determines can normally be resident in IMS network；If can be in IMS nets
Network is normally resident, then by selected card labeled as support IP multimedia service, otherwise be then labeled as not supporting.
It should be noted that for some senior standards, the senior standard is registered in when judging once certain subscriber card
In network, other users card directly may be set to GSM standards by terminal, then other users card is obvious
Follow-up judgement cannot be again smoothed out.At this moment need it is previous card judge at the end of allow the card immediately actively from
Net, is judged so that follow-up card can pass through registration.
In a preferred embodiment of the invention, the main card of user also can be directly received after the judgement of all cards terminates
Set, at this moment the result of determination of step S2 is used to set user and points out.Such as user is having at least one
When card supports IP multimedia service, mistakenly have selected and do not support the card of IP multimedia service as main card,
User then is pointed out by appropriate mode, informs that user has more excellent main card to select so that user correctly adjusts master
Card is set, it is ensured that user normally uses every business.Appropriate prompting was included with appropriate opportunity and/or appropriate
Means are pointed out, such as the prompting such as figure, word, vibration, sound, light is directly carried out when user is set,
Or pointed out etc. again when user selects main card using the IP multimedia service do not supported；Prompting means
With user can be caused to note and excessively interference user's current operation for preferential.
Embodiment two
In a preferred embodiment of the invention, further illustrated by taking VoLTE double-terminals as an example preferred
Main card selection scheme.When user uses VoLTE double-terminals, if two subscriber cards of user's insertion are equal
It is usim card, then double card combination has three kinds of situations：Two cards all support VoLTE；One card supports VoLTE,
One card does not support VoLTE；Two cards do not support VoLTE.Terminal inserts two cards and is usim card
When, terminal cannot differentiate whether this usim card supports VoLTE before no and network sets up connection,
But terminal can recognize that this two cards are all usim cards.
By flow and method as shown in Figure 2, the preferred embodiment of the present invention realizes VoLTE double-terminals and writes from memory
Recognizing will support that the USIM of VoLTE is set to main card, or provide a user with related prompting, and guiding user correctly selects
Select.Specifically, the method for Fig. 2 includes：
Two user's card informations of insertion are read, if two cards are all usim cards, this information one is done
Individual mark：All_USIM_FLAG=1, main card selection is not carried out now；Otherwise (i.e. only one is USIM
Card or the situation without usim card), prioritizing selection usim card is main card or receives the main card setting of user；
If All_USIM_FLAG=1, in selecting any one draw-in groove (labeled as SIM_SLOT1)
Usim card carries out LTE network registration, then carries out IMS registration, if the usim card in this draw-in groove can
Normally it is resident with IMS network, then illustrates that this usim card supports VoLTE, mark
SIM_SLOT1_USIM_VoLTE_FLAG=1；Otherwise illustrate that this usim card does not support VoLTE, mark
Note SIM_SLOT1_USIM_VoLTE_FLAG=0；
Selecting the usim card in another draw-in groove (labeled as SIM_SLOT2) carries out LTE network note
Volume, then carries out IMS registration, if the usim card in this draw-in groove can be normally resident in IMS network,
Then illustrate that this usim card supports VoLTE, mark SIM_SLOT2_USIM_VoLTE_FLAG=1；It is no
Then illustrate that this usim card does not support VoLTE, mark SIM_SLOT2_USIM_VoLTE_FLAG=0；
Wherein, if SIM_SLOT1_USIM has been registered in LTE network before, terminal is possible to
SIM_SLOT1_USIM directly can be set to GSM, for such case, it is necessary to be determined foregoing
After the VoLTE tenabilities of SIM_SLOT1_USIM, make its active off-network immediately, so as to ensure right
SIM_SLOT2_USIM carries out LTE registrations.
To SIM_SLOT1_USIM_VoLTE_FLAG and SIM_SLOT2_USIM_VoLTE_FLAG
Carry out logic and operation：If SIM_SLOT1_USIM_VoLTE_FLAG＆SIM_SLOT2_USIM_
VoLTE_FLAG=1, then illustrate that two USIM support VoLTE, now enters directly into user's selection
Interface or ejection user's selection menu, main card is selected by user；
To SIM_SLOT1_USIM_VoLTE_FLAG and SIM_SLOT2_USIM_VoLTE_FLAG
Carry out logic or computing：If SIM_SLOT1_USIM_VoLTE_FLAG | SIM_SLOT2_USIM_
VoLTE_FLAG=0, then illustrate that two USIM do not support VoLTE, now equally enter directly into use
Family selection interface or ejection user's selection menu, main card is selected by user；
To SIM_SLOT1_USIM_VoLTE_FLAG and SIM_SLOT2_USIM_VoLTE_FLAG
Judge respectively, if SIM_SLOT1_USIM_VoLTE_FLAG=1 and SIM_SLOT2_USIM_
VoLTE_FLAG=0, then be directly set to main card by SIM_SLOT1_USIM, and reside in LTE and
IMS, SIM_SLOT2_USIM are set to vice card and only support GSM；If SIM_SLOT1_USIM_VoLTE_
FLAG=0 and SIM_SLOT2_USIM_VoLTE_FLAG=1, then directly by SIM_SLOT2_USIM
It is set to main card, and resides in LTE and IMS, SIM_SLOT1_USIM are set to vice card and only support GSM.
Additionally, when user sets major and minor card manually, according to SIM_SLOT1_USIM_VoLTE_FLAG
Judged with SIM_SLOT2_USIM_VoLTE_FLAG, if based on card that value is 0 is set
Card, illustrates that user error ground will not support that the card of VoLTE is set to main card, and terminal will be caused to use
VoLTE business, can now point out user by the way of appropriate.
Embodiments of the invention two are simply main in an application scenarios using being illustrated as a example by VoLTE double-terminals
The detailed process of card selection, relevant technical staff in the field is appreciated that IMS can provide IP multimedias clothes
Business is not limited in VoLTE, other include but is not limited to VoIP, unified CENTREX, enterprise's Fetion,
Click to dial, IMS mediaphones, IMS multimedia conferencings, IMS electronic faxs, IMS PGM and many
The business such as media CRBT can be supported by IMS.Therefore the VoLTE double card scenes of embodiment two should not be construed as
Limitation to the specific embodiment of the invention, technical scheme obviously also may be used in above-mentioned business；
Similarly, double card and LTE standards etc. are also not construed as to concrete restriction of the invention.
Whether it is that can determine whether to support or do not prop up by simple logical operation when double card
Hold VoLTE；And during for many cards, be accomplished by selecting main card by user when there is two or more card to support,
Simple and/or computing possibly cannot judge, it is necessary to each card judges respectively.But need to only determine whether only during many cards
There is a card to support VoLTE, main card is then set in this way, otherwise carry out user's selection, therefore actual judgement is imitated
Rate is simultaneously unaffected.
