Detailed Description
The present disclosure is further illustrated by way of examples below, but is not thereby limited to the scope of the examples described.
Example 1
The embodiment provides an emergency call control method applied to a mobile terminal, as shown in fig. 1, comprising the following steps:
s1, receiving an emergency call request;
s2, acquiring cell residence states of a plurality of user identification cards in the mobile terminal;
s3, responding to the state that the user identification card is in different cell residence states, and determining a target identification card according to a preset call priority;
s4, controlling the mobile terminal to initiate an emergency call through the target identification card.
Emergency calls refer to the need for a user to quickly acquire emergency services in order to successfully place an emergency call in an emergency situation, and therefore, the speed at which emergency calls are initiated is critical. The speed of initiating emergency calls is affected to a certain extent by factors such as the state of the cell in which the SIM card resides in the handset.
Step S1, an emergency call request is obtained, namely, a user dials an emergency call; step S2, obtaining the current cell residence state of a plurality of SIM cards in the mobile terminal such as a mobile phone and the like, if so, whether the mobile terminal resides in a cell, normally resides or is limited to reside; step S3, determining a target SIM card for initiating an emergency call from a plurality of SIM cards according to preset priorities based on different cell residence states of the SIM cards; and S4, controlling the mobile phone to initiate an emergency call through the target SIM card.
It should be noted that, although the present embodiment is described by taking a mobile phone as an example, the application of the present disclosure is not limited to a mobile phone, and may be applied to any product having a dual-card capability, supporting an emergency call, and supporting a voice function of a cellular network, such as a chip and a terminal.
In the scheme, the current cell residence state of a plurality of SIM cards in the mobile terminal is obtained, the SIM cards are determined to be used for initiating the emergency call according to the preset call priority in response to the different cell residence states of the SIM cards, so that the initiation of the emergency call is based on the actual cell residence state of the SIM cards, the problems of slow emergency call response or unsuccessful call and the like are avoided, and the emergency call efficiency and success rate of the mobile terminals such as mobile phones are improved.
In an embodiment, when there are two subscriber identity cards in the mobile terminal, step S3 includes:
if one of the subscriber identity cards normally resides in a cell which does not support the emergency call and the other subscriber identity card is limited to reside in the cell which supports the emergency call, the subscriber identity card limited to reside in the cell which supports the emergency call is determined to be the target identity card.
Specifically, for a two-card terminal, if one of the SIM cards (card 1) has normally resided in the serving cell a, but the cell a does not support emergency services, i.e., EMC (emergency call field) =0; another SIM card (card 2) is a restricted-resident serving cell B, where the cell B is an NR or LTE cell supporting restricted-resident emergency services, that is, a system message SIB1 (an information) carries ims-emergencysupport=1, or if the cell B is a GSM/WCDMA cell, it is determined that the card 2 is a target identification card, specifically for the following reasons:
(i) As shown in fig. 2, card 1 has been camping on serving cell a, cell a (NR/LTE) does not support emergency services (i.e. emc=0). When the card 1 initiates a request for making an emergency call, the card needs to fall back to other systems to search for the network, and after searching for the network, emergency registration is initiated, and finally the emergency call is initiated.
(ii) As shown in fig. 3, the card 2 is a restricted-camping cell B, which is an NR/LTE cell supporting the restricted-camping emergency service (i.e., carrying ims-emergencysupport=1 in system message SIB 1), or cell B is a GSM/WCDMA cell. When the card 2 initiates a request to make an emergency call, it initiates an emergency registration directly in cell B and then initiates an emergency call.
As can be seen from a comparison of fig. 2 and 3, the process of making an emergency call by card 1 is more time consuming than the process of making an emergency call by card 2 by searching for network actions and steps. In this case, therefore, it is preferable to acquire emergency services from the SIM card of the restricted resident cell, that is, the card 2, as shown in fig. 4, in view of efficiency and speed of acquiring emergency calls; if the situation is not met, the target SIM card for making an emergency call can be determined according to the call card preference of the user, and the call card preference is set by the user.
In the scheme, when one SIM card normally resides in a cell which does not support emergency call and the other SIM card is limited to reside in the cell which supports emergency call, the emergency call is initiated from the SIM card limited to reside in the cell which supports emergency call, so that the time for dialing the emergency call can be shortened, and the efficiency of the emergency call is improved.
In one embodiment, restricting camping on a cell supporting an emergency call includes: restricted camping in NR cell or LTE cell, and limited emergency call field of NR cell or LTE cell is supported; or, is restricted to camping on a WCDMA cell or a GSM cell.
I.e. the limited camping of card 2 in a cell supporting emergency calls comprises two situations: cell B is an NR or LTE cell supporting limited-camping emergency services (i.e., system message SIB1 carries ims-emergencypupport=1); and the second is that the cell B is a GSM or WCDMA cell.
In the scheme, a judging method for judging whether the cells with different systems support the limited resident emergency call is defined, and the accuracy of the emergency call control method is improved.
In one embodiment, when there are at least three subscriber identity cards in the mobile terminal, step S3 includes:
if one of the subscriber identity cards is limited to reside in the cell supporting the emergency call and the other subscriber identity cards are normally resident in the cell not supporting the emergency call, the subscriber identity card limited to reside in the cell supporting the emergency call is determined to be the target identity card.
That is, when only one of the plurality of SIM cards is restricted to reside in a cell supporting an emergency call, the SIM card is determined to be the target SIM card.
If at least two subscriber identity cards are limited to reside in the cell supporting the emergency call, and the rest subscriber identity cards are normally resided in the cell not supporting the emergency call, determining one subscriber identity card with the strongest signal among the subscriber identity cards limited to reside in the cell supporting the emergency call as a target identity card.
That is, when more than one SIM card is limited to reside in the cell supporting the emergency call, it is necessary to further compare the signal strengths of the SIM cards limited to reside in the cell supporting the emergency call, and determine one of the SIM cards having the strongest signal as the target SIM card.
In the scheme, the method for determining the target SIM card under the condition of setting a plurality of SIM cards and taking the signal strength as the basis of comparison can further improve the efficiency of emergency call.
In an embodiment, when there are two subscriber identity cards in the mobile terminal, step S3 further includes:
if one of the subscriber identity cards normally resides in the cell supporting the emergency call and the other subscriber identity card does not reside in the cell and only displays the emergency call, the subscriber identity card normally residing in the cell supporting the emergency call is determined to be the target identity card.
Specifically, for a dual-card terminal, if one of the SIM cards (card 1) has normally resided in the serving cell a, the cell a supports emergency services (i.e., emc=1); the other SIM card does not reside in the service cell, and only can dial an emergency call, and the card 1 which has normally resides in the service cell A is determined to be the target SIM card, specifically for the following reasons:
(i) As shown in fig. 5, the card 1 has normally resided in the serving cell a, and when the card 1 needs to make an emergency call, an emergency bearer establishment request and registration are directly initiated in the cell a, and finally the emergency call is initiated.
(ii) As shown in fig. 6, the card 2 is in a state of not being resident in a cell, showing that only emergency calls can be made, illustrating that the card 2 is restricted to reside in a cell B of some other operator. When the card 2 needs to make an emergency call, the card 2 initiates emergency attachment and makes an emergency call in a cell B which is limited to reside, and if the cell B does not support the emergency service which is limited to reside (the system message SIB1 carries ims-EmerrgencySupport=0), the emergency call fails to make; emergency calls can be placed successfully only if cell B supports restricted-resident emergency services (imms-emergencysupport=1 is carried in system message SIB 1).
As seen from a comparison of the flows of fig. 5 and 6, the initiation of an emergency call from the card 2 may be at risk of failure to acquire emergency services, whether or not successful depends on the policy of the local operator. In this particular case, therefore, from the standpoint of comparing the success rate of acquiring the emergency call, it is preferable to acquire the emergency service from the card that has successfully resided in the serving cell, that is, the card 1, as shown in fig. 7; if the situation is not met, the target SIM card for making the emergency call can be determined by the call card preference of the user.
In the scheme, when one SIM card normally resides in a cell supporting emergency call and the other SIM card does not reside in the cell, and only emergency call dialing is displayed, the SIM card normally residing in the cell supporting emergency call is determined to be a target SIM card, so that the problem of failure in dialing emergency call can be avoided, and the success rate of emergency call is improved.
In an embodiment, when there are at least three subscriber identity cards in the mobile terminal, step S3 further includes:
if one of the subscriber identity cards normally resides in the cell supporting the emergency call, and the other subscriber identity cards do not reside in the cell and display that only the emergency call can be performed, the subscriber identity card normally residing in the cell supporting the emergency call is determined to be the target identity card.
That is, when only one of the plurality of SIM cards normally resides in a cell supporting an emergency call, the SIM card is determined to be the target SIM card.
If at least two subscriber identity cards normally reside in the cell supporting the emergency call, and the other subscriber identity cards do not reside in the cell and only display emergency calls, determining the subscriber identity card with the strongest signal among the subscriber identity cards normally residing in the cell supporting the emergency call as the target identity card.
That is, when more than one SIM card normally resides in the cell supporting the emergency call, it is necessary to further compare the signal strengths of the SIM cards normally residing in the cell supporting the emergency call, and determine one of the SIM cards having the strongest signal as the target SIM card.
In the scheme, the method for determining the target SIM card under the condition of setting a plurality of SIM cards and taking the signal strength as the basis of comparison can further improve the efficiency of emergency call.
In one embodiment, the emergency call control method further comprises:
and in response to that all the subscriber identity cards normally reside in the cell supporting the emergency call, determining one subscriber identity card with the strongest signal in all the subscriber identity cards as a target identity card.
Specifically, for a dual-card terminal, if both SIM cards have normally resided in cell a and cell B, and both cell a and cell B support emergency services (i.e., emc=1), it is easy to see that the flow of acquiring emergency services by the dual-card is the same step in this case. In this case, however, if the signal of the cell a in which the card 1 resides is stronger than the signal of the cell B in which the card 2 resides, the probability of the card 2 dropping is theoretically higher than that of the card 1 dropping. In this particular case, therefore, from the standpoint of comparing the success rate of acquiring an emergency call, it is better to acquire an emergency service from a card with a better resident cell signal, as shown in fig. 8; if the situation is not met, the target SIM card for making the emergency call can be determined by the call card preference of the user.
Also, in the case of multiple SIM cards, if the multiple SIM cards have already been camping on a cell normally, it is better to obtain emergency services from the card with better camping on the cell signal.
In the scheme, for a plurality of SIM cards of the resident cell, the best signal of the resident cell is selected to initiate the emergency call, so that the success rate of the emergency call can be improved.
If the resident states of a plurality of SIM cards in the mobile phone do not belong to the situation when the emergency call is dialed, determining a target SIM card according to the operation of the user.
The emergency call control method provided by the embodiment is only used for improving the speed and the success rate of emergency call, and does not change the priority of each SIM card when a user initiates a common call.
According to the emergency call control method provided by the embodiment, the current cell residence states of a plurality of SIM cards in the mobile terminal are obtained, the SIM cards used for initiating the emergency call are determined according to the preset call priority in response to the different cell residence states of the SIM cards, so that the initiation of the emergency call is based on the actual cell residence states of the SIM cards, the problems of slow emergency call response or unsuccessful call and the like are avoided, and the emergency call efficiency and success rate of mobile terminals such as mobile phones are improved.
