Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Example 1

step 201: after a second SIM card in the terminal sends a call, controlling a network used by the first SIM card to negotiate with a network used by the second SIM card until the negotiation success or the negotiation failure times reach the preset times;
step 202: and controlling the second SIM card to continue executing the call.
The controlling of the network used by the first SIM card and the network used by the second SIM card to negotiate until the number of successful negotiation or failed negotiation reaches a preset number may specifically include:
and controlling the network used by the first SIM card to release the network resources influencing the calling of the second SIM card until the times of successful network resource release or failure of network resource release attempt reach the preset times.
Preferably, in this embodiment, the first SIM card registers in the LTE network, and the second SIM card registers in the GSM network, that is, the first SIM card registers in the LTE network, and the second SIM card registers in the non-LTE network, based on which, the network used by the first SIM card and the network used by the second SIM card are controlled to negotiate until the number of times of negotiation success or negotiation failure reaches a preset number, which may specifically include:
and controlling the network used by the first SIM card to release the RRC connection until the times of the successful RRC connection release or the failed RRC connection release reach preset times.
Further, controlling a network used by the first SIM card to negotiate with a network used by the second SIM card until the number of successful negotiations or failed negotiations reaches a preset number, including:

and if the RRC connection release fails, continuing to perform the RRC connection release attempt, reducing the number of attempts on the basis of the preset number, and if the RRC connection release succeeds, controlling the second SIM card to continue to perform the call.
Example 2
The present embodiment further describes the multi-SIM card terminal call control device provided in the present invention by disclosing more technical details.
In this embodiment, a concept of maximum number of times of RRC connection release retries is introduced, and when the first SIM card registers the LTE network, the second SIM card registers the GSM network, and the second SIM card calls through the GSM, as shown in fig. 3, a call control process according to the embodiment of the present invention is as follows:
firstly, the first SIM card releases the RRC connection of the LTE by using a CSFB signaling flow, if the RRC connection release fails, the times of the RRC connection release retry are sequentially reduced, namely, the operation of n-1 is executed. And if the retry number is reduced to 0 time and the RRC connection is not released at the time, the second SIM card GSM ignores the RRC release of the first SIM card LTE and continues to complete the call flow. If the RRC connection release is successful before the retry number is reduced to 0, the GSM of the second SIM card is informed, and the second SIM card continues to complete the call through the GSM.
The scheme of the embodiment avoids the situation that the second SIM card cannot continue to call due to the failure of LTE RRC connection, and simultaneously, the original design flow is kept to the maximum extent, and the RRC connection is released as soon as possible.
In the scheme of this embodiment, the number n of retries for RRC connection release needs to be determined first, after a call is sent, there is a time limit between each procedure, and after a certain request is sent, if a timeout does not respond, the call will also fail. Therefore, the retry number is selected by combining the time of the RRC connection release procedure and the maximum RRC release return time tolerated by the GSM caller.
