Embodiment 1

[0023] This embodiment provides a multi-SIM card terminal call control method, the method is used to control the call of a multi-SIM card terminal, and the method is applied to the terminal side, such as figure 2 As shown, the method may specifically include the following processing:

[0024] Step 201: After the second SIM card in the terminal sends out a call, control the network used by the first SIM card to negotiate with the network used by the second SIM card until the number of successful or failed negotiations reaches a preset number of times;

[0025] Step 202: Control the second SIM card to continue calling.

[0026] Wherein, controlling the network used by the first SIM card to negotiate with the network used by the second SIM card until the number of times the negotiation succeeds or fails reaches a preset number of times, specifically may include:

[0027] Controlling the network used by the first SIM card to release network resources affecting calls made by the ...

Embodiment 2

[0034] This embodiment further describes the multi-SIM card terminal call control device provided by the present invention by disclosing more technical details.

[0035] This embodiment introduces the concept of the maximum number of RRC connection release retries. When the first SIM card is registered with the LTE network, the second SIM card is registered with the GSM network, and the second SIM card is called by GSM, as image 3 As shown, the call control flow of the embodiment of the present invention is as follows:

[0036] After the second SIM card sends a call, the GSM of the second SIM card negotiates with the LTE of the first SIM card: first, the first SIM card borrows the CSFB signaling process to release the RRC connection of LTE, if the release of the RRC connection fails, the RRC connection The number of release retries decreases in turn, that is, n=n-1 operations are performed. If the number of retries is reduced to 0 and the RRC connection has not been released...

Embodiment 3

[0040] This embodiment provides a multi-SIM card terminal call control device, which is used to implement the multi-SIM card terminal call control method proposed in Embodiment 1 and Example 2 of the present invention, the device is arranged on the terminal side, Figure 4 is a structural block diagram of the device 40, such as Figure 4 As shown, the device includes the following components:

[0041] The negotiation module 41 is used to control the network used by the first SIM card to negotiate with the network used by the second SIM card after the second customer identification module SIM card in the terminal sends a call, until the number of times that the negotiation succeeds or fails reached the preset number of times;

[0042] The calling module 42 is configured to control the second SIM card to continue calling.

[0043] Wherein, the negotiation module 41 is specifically used to: control the network used by the first SIM card to release the network resources that aff...

Abstract

The invention provides a calling control method and a calling control device for a multi-SIM card terminal, used for solving the problem that in the prior art, the SIM registered in GSM is failed to make a call as a RRC connection is failed to release. The method comprises the steps of after a SIM card in the terminal initiates a call, controlling a network used by the first SIM card to negotiate with the network used by the second SIM card, until the time of successful negotiation and failed negotiation reaches a preset time; and controlling the second SIM card to continuously execute calling. According to the scheme of the method and the device provided by the invention, a success rate of calling is improved.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a method and device for controlling calls of multiple SIM card terminals. Background technique [0002] Currently, in a DSDS (Dual SIM Dual Standby, dual card dual standby) terminal, one (the first SIM card) of the two SIM (Subscriber Identity Module, customer identification module) cards of the terminal is registered in the LTE (Long Term Evolution, Long Term Evolution) network, another (second SIM card) is registered in the GSM (Global System for Mobile Communications, Global System for Mobile Communications) network, if you need to use the SIM card registered in the GSM network to make a call, you need to follow the figure 1 The shown process is executed. First, the first SIM card uses the CSFB (Circuit Switched Fallback, Circuit Switched Fallback) signaling process to release the RRC (Radio Resource Contorl, Radio Resource Control) connection of LTE. When the R...
