Description

Processing method, terminal and chip system for receiving incoming call in conference

Technical Field

The embodiment of the application relates to the technical field of communication, in particular to a processing method, a terminal and a chip system for receiving an incoming call in a conference.

Background

With the development of communication technology, many terminals (such as mobile phones) are increasingly configured and have increasingly powerful functions, so that users can use Applications (APP) installed on the terminals to perform work or entertainment and leisure on the terminals at any time and any place. For example, a user may conduct a conference using a conference APP installed on a terminal.

If the terminal receives an incoming call (i.e. a cellular phone) during a conference in which the user is using the terminal, there is a problem that the conference is stuck or interrupted due to the network. In addition, since the priority of the cellular phone is highest, after the terminal receives the incoming call, there is a problem that the call interface covers the conference interface and the conference is silent.

Disclosure of Invention

The embodiment of the application provides a processing method, a terminal and a chip system for receiving an incoming call in a conference, which are used for solving the problems that after the terminal receives the incoming call in the conference, the conference is blocked or interrupted, a conference interface is covered and the conference is silent.

In order to achieve the above purpose, the embodiments of the present application adopt the following technical solutions:

in a first aspect, a processing method for receiving an incoming call in a conference is provided, the processing method is applied to a terminal, the terminal is provided with two Subscriber Identity Module (SIM) card slots, and the two SIM card slots are respectively inserted into a first SIM card and a second SIM card; the processing method comprises the following steps: in a dual-card dual-standby DSDS mode, the terminal resides in a cell of a first network system supported by the DSDS mode through a first SIM card, joins an online conference through a network signal provided by the first SIM card, and displays a conference interface.

And responding to the terminal joining the online conference, wherein the terminal works in a DSDA mode, resides in a cell of a second network system supported by the DSDA mode through a first SIM card, and resides in a cell of a third network system supported by the DSDA mode through a second SIM card.

After receiving the first incoming call request message through the second SIM card, the terminal continuously resides in a cell of a third network system supported by the DSDA mode through the second SIM card; and then, the terminal responds to the first incoming call request message to carry out a first incoming call reminder on the conference interface, wherein the first incoming call reminder does not cover the conference interface and does not ring.

In the related art, a terminal works in a DSDS mode, and a first SIM card and a second SIM card in the terminal share a set of radio frequency resources; in the process that the first SIM card occupies radio frequency resources for meeting, when the second SIM card receives an incoming call, the second SIM card occupies the radio frequency resources used by the first SIM card when the meeting is carried out because the priority of the cellular telephone is highest, so that the first SIM card has no radio frequency resources available, and the meeting is blocked or interrupted. In addition, when the terminal works in the DSDA mode and the first SIM card receives an incoming call in the process of meeting, if the second SIM card does not start the VoNR function, the second SIM card can be switched to a cell in which the LTE system resides, so that the terminal is switched from the DSDA mode to the DSDS mode, and the meeting is blocked or interrupted. And, because the priority of the cellular phone is highest, after the second SIM card in the terminal receives the incoming call, the caller id display interface will cover the conference interface, and the terminal will switch the audio channel to the call, resulting in silence of the conference.

In summary, by adopting the scheme provided by the application, when the terminal currently works in the DSDS mode, the first SIM card resides in a cell of a first network system supported by the DSDS mode and enters a conference, and the terminal works in the DSDA mode, so that the first SIM card and the second SIM card in the terminal respectively occupy a set of radio frequency resources; after the second SIM card receives the first incoming call request, the second SIM card of the terminal continuously resides in a cell of a third network system supported by the DSDA mode, so that the second SIM card in the terminal can be ensured not to influence the first SIM card to carry out a conference after receiving the incoming call, and the problem of conference blocking or interruption caused by the incoming call is solved.

In addition, after the terminal receives the incoming call, the terminal carries out first incoming call reminding on the conference interface, and the first incoming call reminding does not cover the conference interface and does not ring, so that the problem that the conference interface is covered and the problem that the conference is silent can be solved.

Optionally, the second network system and the third network system are one of a combination of systems of DSDA modes supported by the terminal.

Or, alternatively, the cell corresponding to the third network system is a cell corresponding to a first frequency band of the DSDA mode supported by the terminal, the cell corresponding to the third network system is a cell corresponding to a second frequency band of the DSDA mode supported by the terminal, and the first frequency band and the second frequency band are a frequency band combination supporting the DSDA mode corresponding to a system combination of the DSDA mode supported by the terminal.

Optionally, the second network system is a 5G system, and the third network system is a 5G system.

Or, alternatively, the second network system is a 5G system, and the frequency band corresponding to the cell of the second network system is a first frequency band specified by the 5G protocol; the third network system is a 4G system, and the frequency band corresponding to the cell of the third network system is a second frequency band specified by the 4G protocol.

In a possible implementation manner of the first aspect, the processing method further includes: after receiving the first incoming call request message through the second SIM card, the terminal continuously resides in a cell of a second network system supported by the DSDA mode through the first SIM card.

Therefore, the problem that the conference is blocked or interrupted after the terminal receives the incoming call in the conference can be further solved.

In a possible implementation manner of the first aspect, after the terminal joins the online conference, the processing method further includes: the terminal receives a second incoming call request message through the first SIM card; after the terminal receives the second incoming call request message, the terminal continues to reside in the cell of the second network system supported by the DSDA mode through the first SIM card.

And the terminal responds to the second incoming call request message to carry out a second incoming call reminder on the conference interface, wherein the second incoming call reminder does not cover the conference interface and does not ring.

In this way, under the condition that the terminal joins the online conference through the first SIM card, the first SIM card continuously resides in the cell of the second network system supported by the DSDA mode under the condition that the first SIM card of the terminal receives the incoming call, and the switching to the cell of other network systems is avoided, so that the problem that the conference is blocked or interrupted due to the fact that the terminal receives the incoming call in the conference can be solved.

In addition, after the terminal receives the incoming call, the terminal carries out a second incoming call reminder on the conference interface, and the second incoming call reminder does not cover the conference interface and does not ring, so that the problem that the conference interface is covered and the problem that the conference is silent can be solved.

In a possible implementation manner of the first aspect, the processing method further includes: and after the terminal responds to the second incoming call prompt and the incoming call is put through the first SIM card, the terminal carries out online conference by the network signal provided by the first SIM card, and switches to the network signal provided by the second SIM card to continue the online conference.

Therefore, after the first SIM card of the terminal receives the incoming call, the terminal can switch to the network signal provided by the second SIM card to continue the online conference, so that the continuity of the conference can be ensured, and the incoming call is prevented from affecting the conference.

In a possible implementation manner of the first aspect, the processing method further includes: the terminal responds to the first incoming call prompt, and after the terminal is connected with an incoming call through the second SIM card, the online conference carried out by the terminal through the first SIM card is in a mute state.

In a possible implementation manner of the first aspect, the terminal resides in a cell of a third network system supported by the DSDA mode through a second SIM card, including: if the terminal does not start the voice transmission service corresponding to the third network system, the terminal starts and keeps starting the voice transmission service corresponding to the third network system, and the terminal resides in a cell of the third network system supported by the DSDA mode through the second SIM card.

If the terminal starts the voice transmission service corresponding to the third network system, the terminal keeps starting the voice transmission service corresponding to the third network system, and the terminal resides in a cell of the third network system supported by the DSDA mode through the second SIM card.

Therefore, as the terminal starts and keeps starting the voice transmission service corresponding to the third network system, after the second SIM card receives the incoming call, the second SIM card is prevented from being switched into the cell corresponding to the other network system, and the problem that the conference is blocked or interrupted after the terminal receives the incoming call in the conference can be solved.

Optionally, the third network system is a 5G system, and the voice transmission service is a VoNR voice service. Or the third network system is a 4G system, the frequency band corresponding to the cell of the third network system is a second frequency band specified by the 4G protocol, and the voice transmission service is VoLTE voice service.

In a possible implementation manner of the first aspect, the processing method further includes: after the terminal exits the online conference, the terminal closes the voice transmission service corresponding to the third network system; and/or after the terminal exits the online conference, the terminal works in a DSDS mode, resides in a cell of a first network system supported by the DSDS mode through a first SIM card, and resides in a cell of a fourth network system supported by the DSDS mode through a second SIM card.

In a possible implementation manner of the first aspect, the terminal includes a system user interface system UI and a Modem, the system UI including a switch of a conference mode; the terminal works in a DSDA mode and comprises: responding to the operation of opening a switch of the conference mode by a user, and sending a first indication message to the Modem by the system UI so as to instruct the terminal to enter the conference mode; and responding to the first indication message, the Modem searches cells of the second network system and the third network system so as to enable the terminal to work in the DSDA mode.

In a possible implementation manner of the first aspect, the terminal responds to the first incoming call request message to perform a first incoming call reminder at the conference interface, including: the terminal responds to the first incoming call request message, and carries out first incoming call reminding on a conference interface in a floating window or popup window mode and in a vibration, mute or flash lamp flashing mode.

The following terms "first", "second" are used for descriptive purposes only and are not to be construed as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Thus, a feature defining "a first" or "a second" may explicitly or implicitly include one or more such feature. In the description of the embodiments of the present application, unless otherwise indicated, the meaning of "a plurality" is two or more.

In the embodiments of the present application, words such as "exemplary" or "such as" are used to mean serving as examples, illustrations, or descriptions. Any embodiment or design described herein as "exemplary" or "for example" should not be construed as preferred or advantageous over other embodiments or designs. Rather, the use of words such as "exemplary" or "such as" is intended to present related concepts in a concrete fashion.

For ease of understanding, technical terms related to embodiments of the present application are explained first.

Standard combination: the system combination is a combination of radio access technologies (radio access technology, RATs) supported by the terminal, including but not limited to 2G, 3G, 4G, 5G, etc., for example, RATs may include global system for mobile communications (global system of mobile communication, GSM), code division multiple access (code division multiple access, CDMA), wideband code multiple access (wideband code division multiple access, WCDMA), universal mobile telecommunications system (universal mobile telecommunication system, UMTS), long term evolution (long term evolution, LTE), and New Radio (NR), etc. The metric combination may be a combination of at least two RATs in GSM, CDMA, WCDMA, UMTS, LTE and NR.

Frequency band combination: the frequency band combination is a frequency band combination adopted by the RAT supported by the terminal, and frequency bands adopted by different RATs can be designated in the frequency band combination.

Dual card dual standby (dual SIM dual standby, DSDS): the dual card dual standby may also be referred to as dual card dual standby single pass, and two subscriber identity modules (subscriber identification module, SIM) cards inserted in a terminal supporting the DSDS mode may be simultaneously in a standby state, but one SIM card is in an unavailable state when the terminal makes a round of call through the other SIM card. If the terminal is a calling party, a round of call comprises calling, call establishment and call establishment; if the terminal is the called party, a round of call includes receiving a call, establishing a call, and calling. In the embodiment of the application, the SIM card is in an unavailable state because the SIM card has no network signal, so that both the data service of the SIM card and the voice service of the SIM card cannot be used.

Double-card double-pass (dual SIM dual active): the dual-card dual-pass can also be called as dual-card dual-standby dual-pass, and the terminal supporting the DSDA mode has the capability of surfing the internet by using one SIM card in the process of calling the other SIM card (DSDA capability for short) because the two SIM cards have concurrent capability, so that the other SIM card is in an available state when the terminal performs one-round call through the one SIM card.

The following describes in detail the technical solutions provided in the embodiments of the present application with reference to the drawings attached to the specification.

The technical solution of the embodiments of the present application may be applied to various communication systems, such as Wi-Fi (wireless fidelity) communication systems, vehicle-to-object (vehicle to everything, V2X) communication systems, inter-device (D2D) communication systems, internet of vehicles communication systems, 4th generation (4th generation,4G) mobile communication systems (e.g., LTE systems), worldwide interoperability for microwave access (worldwide interoperability for microwave access, wiMAX) communication systems, 5G communication systems (e.g., new radio, NR) systems), and future communication systems (e.g., sixth generation (6th generation,6G) mobile communication systems), etc.

The communication system may include a terminal, a network device, a core network device, and the like. A terminal may also be referred to as a terminal device (terminal equipment), user Equipment (UE), mobile station, mobile terminal, etc. The terminal in the embodiment of the present application may be a communication device capable of installing at least two SIM cards, and performing voice communication with other communication terminals by using any one of the at least two SIM cards. For example, the terminal may be a dual-card dual-standby handset, a smart watch capable of installing two SIM cards, a smart bracelet, a tablet computer, or the like. The specific technology and the specific equipment form adopted by the terminal are not limited in the application.

The network device is an access device that a terminal accesses to a communication system in a wireless manner, and may be an Access Point (AP) in a Wi-Fi communication system (such as a home gateway, a router, a server, a switch, a bridge, etc.), an evolved Node B (eNB), a radio network controller (radio network controller, RNC), a Node B (Node B, NB), a base station controller (base station controller, BSC), a base transceiver station (base transceiver station, BTS), a home base station (e.g., home evolved Node B, or home Node B, HNB), a baseband unit (BBU), a wireless relay Node, a wireless backhaul Node, a transmission point (transmission and reception point, TRP, or transmission, TP), etc. It may also be a 5G (such as a gNB in NR or a transmission point (TRP or TP)), one or a group (including a plurality of antenna panels) of the base stations in the 5G system, or may also be a network node (such as a baseband unit BBU, or a Distributed Unit (DU)) constituting the gNB or the transmission point, a Road Side Unit (RSU) having a base station function, or the like. The specific technology and specific device configuration adopted by the network device are not limited in this application.

It should be noted that, the core network device in the embodiments of the present application may include an internet protocol (internet protocol, IP) multimedia subsystem (IP multimedia subsystem, IMS) network and an internet network.

Among them, IMS is a new multimedia service format, which can meet the needs of more novel and diversified multimedia services of clients. IMS is considered as a core technology of the next generation communication network, and can implement convergence of a mobile network and a fixed network. Session initiation protocol (session initialization protocol, SIP) is employed in IMS, so that voice over IP (voice over internet protocol, voIP) can be implemented in LTE or NR. VoIP is called a long term evolution voice bearer (VoLTE) in LTE, and a new air-to-air voice bearer (VoNR) in NR.

VoLTE refers to the carrying of call data by the evolved packet system (evolved packet system, EPS) during a call. The terminal 20 may call the terminal 10 by VoLTE, that is, the terminal 20 requests that control plane signaling (IMS signaling) and user plane data (IMS traffic) involved in the call between the terminal 20 and the terminal 10 be packaged into IP packets and transmitted through EPS and IMS.

VoNR refers to call data carried by a 5G system (5G system,5 gs) during a call. The terminal 20 may call the terminal 10 by VoNR, i.e. the terminal 20 requests that the control plane signaling (IMS signaling) and the user plane data (IMS traffic) involved in the call between the terminal 20 and the terminal 10 be packaged into IP packets and transmitted through 5GS and IMS.

Fig. 1 is a schematic diagram of an application scenario of a processing method for receiving an incoming call in a conference according to an embodiment of the present application. The terminal 10 shown in fig. 1 may be the above-mentioned terminal with two SIM cards, such as the SIM card 1 and the SIM card 2. The SIM card 1 in the terminal 10 may be a main card of the terminal 10, the SIM card 2 may be a sub-card of the terminal 10, or the SIM card 2 in the terminal 10 may be a main card of the terminal 10, and the SIM card 1 may be a sub-card of the terminal 10.

For example, each of the two SIM cards of the terminal 10 in the embodiment of the present application may support a SIM card of any one of the standards GSM, CDMA, WCDMA, UMTS, LTE and NR. For example, the SIM card 1 in the terminal 10 may support the LTE system, and the SIM card 2 may support the LTE system, so that the terminal 10 may support the DSDS mode. Alternatively, the SIM card 1 in the terminal 10 may support the NR system, and the SIM card 2 may support the LTE system, so that the terminal 10 may support the DSDS mode. Or, the SIM card 1 in the terminal 10 may support a first frequency band specified by a 5G protocol corresponding to a cell in NR format, and the SIM card 2 may support a second frequency band specified by a 4G protocol corresponding to a cell in LTE format, so that the terminal 10 may support DSDA mode. Alternatively, the SIM card 1 in the terminal 10 may support the NR system, and the SIM card 2 may support the NR system, so that the terminal 10 may support the DSDA mode.

The terminal 10 can perform an online conference with the terminal 20 through the installed conference APP and using the SIM card 1 in the terminal 10. On this basis, the terminal 30 can also make a call to the SIM card 2 in the pair of terminals 10 to request a voice call with the user holding the terminal 10 through the SIM card 2 of the terminal 10.

During the online conference between the terminal 10 and the terminal 20 using the SIM card 1, if the terminal 30 initiates a call to the SIM card 2 of the terminal 10, the terminal 10 displays an incoming call reminding interface to remind the SIM card 2 of the incoming call. Because the priority of the cellular telephone is highest, the incoming call reminding interface will cover the conference interface, and the audio channel will switch to the conversation, resulting in silence of the conference. In addition, when the SIM card 2 of the terminal 10 receives the call request of the terminal 30, the SIM card 2 of the terminal 10 may preempt the radio frequency resource of the SIM card 1 because the priority of the cellular phone is highest, and when the terminal 10 uses the SIM card 1 to perform a conference, a problem of conference blocking or interruption may occur.

Accordingly, if the terminal 30 initiates a call to the SIM card 1 of the terminal 10 during the online conference between the terminal 10 and the terminal 20 using the SIM card 1, the terminal 10 displays an incoming call reminding interface to remind the SIM card 1 of the incoming call. Because the priority of the cellular telephone is highest, the incoming call reminding interface will cover the conference interface, and the audio channel will switch to the conversation, resulting in silence of the conference. In addition, when the SIM card 1 of the terminal 10 receives the call request of the terminal 30, the SIM card 1 of the terminal 10 may involve a mode switch (e.g. switch from NR to LTE) due to network or terminal reasons, so that a problem of conference blocking or interruption may occur when the terminal 10 uses the SIM card 1 to perform a conference.

In addition, in the embodiment of the present application, when the terminal 10 uses the data network of the SIM card 1 to provide a hotspot for other terminals (such as tablet computers), if the terminal 10 receives an incoming call, the other terminals are disconnected, and the problem of network access card disconnection occurs. For example, when other terminals use the hot spot provided by the terminal 10 to simultaneously conference with the

terminals

10 and 20, if the terminal 10 receives an incoming call, the problem of the conference being blocked or interrupted occurs between the other terminals and the terminal 10.

Referring to fig. 2, an interface diagram of an incoming call received during a conference is shown. Wherein both the SIM card 1 and the SIM card 2 of the terminal 10 reside in a cell of the NR system. Illustratively, as shown in fig. 2 (1), the network icons of the SIM card 1 and the SIM card 2 of the terminal 10 are both shown as 5G. In a scenario where the terminal 10 is conducting a conference using the SIM card 1, the terminal 10 displays a conference interface shown in (1) in fig. 2. In the case where the SIM card 2 of the terminal 10 receives an incoming call, as shown in (2) of fig. 2, since the priority of the cellular phone is highest, the incoming call alert interface covers the conference interface while the conference interface is displayed in a floating window over the incoming call alert interface.

In the interface shown in fig. 2 (2), since the priority of the cellular phone is highest, the audio channel of the terminal 10 is switched to the call at this time, resulting in silence of the conference. And the SIM card 2 is switched from the NR system cell to the LTE system cell, as shown in fig. 2 (2), and the network icon of the SIM card 2 is switched from 5G to 4G.

Accordingly, if the user selects to reject the incoming call of the SIM card 2, after rejecting the incoming call of the SIM card 2, the terminal 10 displays an interface as shown in (3) of fig. 2, and the interface displays a prompt message such as "network is unstable, … is being connected", etc. as shown in (3) of fig. 2.

It should be noted that, in the case where the terminal 10 receives an incoming call in a scenario where the terminal 10 is conducting a conference using the SIM card 1, the terminal 10 has the same or similar interface as that of fig. 2, and reference is made to the above embodiment, which is not illustrated here.

In summary, in the related art, if the terminal 10 receives an incoming call during the conference, the incoming call alert interface covers the conference interface, the conference is silent, and the conference is blocked or interrupted.

Taking an example that the terminal 10 is currently operating in the DSDA mode and the SIM card 1 and the SIM card 2 of the terminal 10 are both resident in the NR-mode cell, fig. 3 shows a flow in which the SIM card 1 of the terminal 10 receives an incoming call of the terminal 30 during a conference with the terminal 20 using the SIM card 1, resulting in silence, a conference card, or an interruption of the conference, which may include the following steps:

S10, the terminal 10 is currently operated in a DSDA mode, and a conference is conducted with the terminal 20 by using the SIM card 1.

S11, the terminal 10 uses the SIM card 1 to transmit conference data to the terminal 20 through the NR network device and the IMS network device.

Accordingly, the terminal 20 may also transmit conference data to the terminal 10 through the NR network device, the IMS network device.

If the conference is a video conference, the conference data includes video data and voice data. If the conference is a voice conference, the conference data includes voice data.

S12, the terminal 30 initiates a call to the SIM card 2 of the terminal 10 through the NR network device and the IMS network device, so as to invite the terminal 10 to make a call.

Illustratively, the terminal 30 may send an invite message (e.g., invite message) to the SIM card 2 of the terminal 10 via the NR network device, the IMS network device, to invite the terminal 10 to make a call.

S13, the NR network equipment inquires that the SIM card 2 of the terminal 10 does not start the VoNR voice service.

S14, the NR network device sends a switching/redirecting instruction message to the SIM card 2 in the terminal 10, and the switching/redirecting instruction message is used for instructing the SIM card 2 of the terminal 10 to switch/redirect to a cell in an LTE system.

The handover/redirection indication message may be, for example, a radio resource control (radio resource control, RRC) connection release. Alternatively, the handover/redirection indication message may also be a redirection message. The embodiments of the present application are not limited in this regard.

For example, when the handover/redirection indication message is an RRC message, the RRC message may be represented as RRC release with LTE frequency, for example.

S15, the SIM card 2 in the terminal 10 establishes RRC connection with the LTE network equipment.

For example, in S13, if the terminal 10 receives the RRC message sent by the NR network device, the terminal 10 is instructed to switch to the LTE-system cell. The terminal 10 transmits an RRC connection request to the LTE network device to request establishment of an RRC connection. After the LTE network device receives the RRC connection request sent by the terminal 10, if the LTE network device chooses to accept the RRC connection request, the LTE network device may send an RRC accept message to the terminal 10, so that the terminal 10 and the LTE network device establish an RRC connection.

S16, the SIM card 2 in the terminal 10 resides in a cell of the LTE system through a tracking area update (tracking area update, TAU) process.

S17, the terminal 10 is switched from the DSDA mode to the DSDS mode, and the SIM card 2 occupies radio frequency resources, so that the conference is blocked or interrupted.

In S17, after the SIM card 2 in the terminal 10 resides in the LTE cell, the SIM card 2 in the terminal 10 is switched from the NR network to the LTE network (e.g., the network icon of the SIM card 2 is changed from 5G to 4G). In this case, the SIM card 1 of the terminal 10 resides in a cell of the NR system and the SIM card 2 resides in a cell of the LTE system, so that the terminal 10 is switched from the DSDA mode to the DSDS mode. In the DSDS mode, the terminal 10 shares a radio frequency resource with the SIM card 1 and the SIM card 2, and the SIM card 2 in the terminal 10 occupies the radio frequency resource because the priority of the cellular phone is highest, so that the SIM card 1 of the terminal 10 has no radio frequency resource available. In this way, the conference data cannot be continuously transmitted when the terminal 10 and the terminal 20 are in a conference using the SIM card 1, thereby causing a conference to be stuck or interrupted.

S18, the SIM card 2 in the terminal 10 sends 183 a session progress message/180 ringing message to the terminal 30 through the LTE network device and the IMS network device.

Wherein, 183session progress message is used to inform terminal 30 that the call is in process; 180ringing messages are used to inform the terminal 30 that the terminal 10 has ringing. Illustratively, the 183session progress message may be, for example, a 183session progress,180 Ringing message, and may be, for example, 180Ringing.

S19, after the terminal 10 sends 180ringing messages to the terminal 30, the terminal 10 displays an incoming call reminding interface.

Illustratively, after the terminal 10 sends 180 a message to the terminal 30, the terminal 10 notifies the call application of the terminal 10 through the Modem to perform an incoming call alert, so as to display an incoming call alert interface.

S20, because the priority of the cellular phone is highest, the incoming call reminding interface displayed by the terminal 10 covers the conference interface, and the terminal 10 switches the audio channel to the incoming call of the SIM card 2, resulting in silence of the conference.

S21, in response to refusing the incoming call of the SIM card 2 by the user, the SIM card 2 in the terminal 10 sends a call termination message to the terminal 30 through the LTE network equipment and the IMS network equipment so as to refuse the incoming call of the SIM card 2.

The call termination message may be, for example, "Cancel, cause=user busy".

S22, after the incoming call of the SIM card 2 in the terminal 10 is refused, the SIM card 1 occupies the radio frequency resource to resume the conference with the terminal 20.

Illustratively, after the incoming call of the SIM card 2 in the terminal 10 is rejected, the SIM card 2 gives the radio frequency resource back to the SIM card 1, and the SIM card 1 resumes the conference with the terminal 20 based on the radio frequency resource.

It should be noted that, in the scenario where the terminal 10 is currently operating in the DSDS mode, when the terminal 10 uses the SIM card 1 to perform a conference with the terminal 20, if the SIM card 2 of the terminal 10 receives a call from the terminal 30, the terminal 10 may also have a problem that the incoming call alert interface covers the conference interface, the conference is silent, the conference is blocked or interrupted, and the specific procedure may be referred to the above embodiment and fig. 3, which are not listed here.

Taking an example that the terminal 10 is currently operating in the DSDA mode and the SIM card 1 and the SIM card 2 of the terminal 10 are both resident in the NR system cell, fig. 4 shows a process in which the terminal 10 uses the SIM card 1 and the terminal 20 to receive an incoming call of the terminal 30 during a conference, and the SIM card 1 of the terminal 10 receives the incoming call of the terminal 30, so that the conference is silent, the conference is blocked or interrupted, which may include the following steps:

s30, the terminal 10 is currently working in a DSDA mode, and a conference is ongoing with the terminal 20 by using the SIM card 1.

S31, the terminal 10 uses the SIM card 1 to transmit conference data to the terminal 20 through the NR network device and the IMS network device.

For an illustration of the specific implementation procedure of S30-S31, reference may be made to S10-S11 in the above embodiment, which is not described herein in detail.

S32, the terminal 30 initiates a call to the SIM card 1 of the terminal 10 through the NR network device and the IMS network device, so as to invite the terminal 10 to make a call.

Illustratively, the terminal 30 may send an invite message (e.g., invite message) to the SIM card 1 of the terminal 10 via the NR network device, the IMS network device, to invite the terminal 10 to make a call.

S33, the NR network equipment inquires that the SIM card 1 of the terminal 10 does not start the VoNR voice service.

S34, the NR network device sends a handover/redirection indication message to the SIM card 1 in the terminal 10, where the handover/redirection indication message is used to instruct the SIM card 1 of the terminal 10 to handover/redirect to a cell in LTE standard.

For the illustration of the handover/redirection indication message in S33, reference may be made to the illustration of S14 in the above embodiment, which is not described herein in detail.

S35, the SIM card 1 in the terminal 10 establishes RRC connection with the LTE network equipment.

For the illustration of S35, reference may be made to the illustration of S15 in the above embodiment, which is not described here again.

S36, the terminal 10 sends a TAU registration request to the LTE network device, where the TAU registration request is used to request that the SIM card 1 in the terminal 10 resides in the LTE cell, and the TAU registration request includes a bearer activation state indication for carrying data services and a bearer activation state indication for carrying voice services.

Wherein, the bearer data service refers to that the bearer channel is used for transmitting video data in the video conference, and the bearer voice service refers to that the bearer channel is used for transmitting voice data in the voice conference or the video conference.

It can be appreciated that, since the TAU registration request is used to request that the SIM card 1 resides in the LTE-compliant cell, the bearer channels included in the TAU registration request are: and carrying channels corresponding to the LTE system.

Illustratively, the TAU registration request may be expressed as: TAU request ebi5=1 and ebi6=1. The EBI5 is an EPS ID of an LTE system for bearing voice service; EBI6 is EPS ID of LTE system for carrying data traffic.

S37, the LTE network device replies a TAU accept message to the terminal 10, where the TAU accept message is used to indicate that the SIM card 1 in the terminal 10 resides in a cell in LTE standard, and the TAU accept message includes an indication that a bearer for carrying a voice service is in an active state.

Illustratively, the TAU accept message may be expressed as: TAU accept ebi5=1 and ebi6=0.

S38, because the LTE network equipment does not have a bearing channel for bearing data service, when the terminal 10 uses the SIM card 1 to carry out the conference, the problem of conference blocking occurs.

After receiving the TAU registration request sent by the terminal 10, the LTE network device queries the NR network device for the context of the terminal 10. It is assumed that the bearer for carrying the data service established by the terminal 10 on the NR network device cannot be transferred to the LTE network device, so that the LTE network device can only query the bearer for carrying the voice service from the NR network device, i.e. the TAU accept message includes ebi5=1, ebi6=0, i.e. the bearer for the voice service is in an active state, and the bearer for the data service is in an inactive state. In this case, since there is no bearer channel for carrying data traffic on the LTE network device, a problem of conference blocking occurs when the terminal 10 uses the SIM card 1 for a conference.

S39, the terminal 10 sends a PDN connection request to the LTE network equipment, and the PDN connection request is used for requesting to establish a bearing channel bearing data service.

Illustratively, the PDN connection request may be expressed as: PDN connection request.

S40, the LTE network device replies a PDN accept message to the terminal 10, for indicating to accept the PDN connection request of the terminal 10, including a bearer channel for carrying data traffic.

S41, because the IP address of the bearing channel for bearing the data service allocated by the LTE network equipment is different from the IP address of the bearing channel for bearing the data service corresponding to the NR network equipment, the conference is interrupted and reconnected.

It should be noted that, in S39, after the LTE network device receives the PDN connection request sent by the terminal 10, the LTE network device reallocates the bearer channel for carrying the data service to the terminal 10, and the IP address of the bearer channel for carrying the data service allocated by the LTE network device is different from the IP address of the bearer channel for carrying the data service corresponding to the NR network device, which results in interruption of the conference. In this case, the terminal 10 may reconnect the conference (i.e., the conference reconnection) based on the bearer channel allocated by the LTE network device for carrying the data traffic.

In addition, even if the IP address of the bearer channel for carrying the data service allocated by the LTE network device is the same as the IP address of the bearer channel for carrying the data service corresponding to the NR network device, the bandwidth when the LTE network device transmits data is small, which may cause a problem of interruption (or jamming) of the conference.

S42, the SIM card 1 in the terminal 10 sends 183 a session progress message/180 ringing message to the terminal 30 through the LTE network device and the IMS network device.

S43, after the terminal 10 sends 180 ringing messages to the terminal 30, the terminal 10 displays an incoming call reminding interface.

S44, since the priority of the cellular phone is highest, the incoming call reminding interface displayed by the terminal 10 covers the conference interface, and the terminal 10 switches the audio channel to the incoming call of the SIM card 1, resulting in silence of the conference.

S45, responding to refusing operation of the user on the incoming call of the SIM card 1, the SIM card 1 in the terminal 10 sends a call termination message to the terminal 30 through the LTE network equipment and the IMS network equipment so as to refuse the incoming call of the SIM card 1.

It should be noted that, for the illustration of S41-S44, reference may be made to the illustration of S17-S20 in the above embodiment, and the details are not repeated here.

S46, the LTE network device sends a handover/redirection instruction message to the SIM card 1 in the terminal 10, for instructing the SIM card 1 of the terminal 10 to handover/redirect to the NR-mode cell.

In S46, for better user experience, if the terminal 10 refuses to receive the incoming call of the SIM card 1 when the SIM card 1 of the terminal 10 falls back to the LTE cell to receive the incoming call of the SIM card 1, the LTE network device will use a fast return function to return the SIM card 1 in the terminal 10 to the NR cell.

S47, the SIM card 1 in the terminal 10 establishes an RRC connection with the NR network device.

S48, the terminal 10 sends a mobility registration update (mobility registration updating, MRU) registration request to the NR network device, where the request is for the SIM card 1 in the terminal 10 to camp on the NR cell, and the MRU registration request includes a bearer channel for carrying data traffic and a bearer channel for carrying voice traffic.

It can be appreciated that, since the MRU registration request is used to request that the SIM card 1 resides in the NR-format cell, the bearer channels included in the MRU registration request are: and carrying channels corresponding to NR modes.

Illustratively, the MRU registration request may be expressed as: MRU request with pdu session status PSI5 =1 and psi6=1. Wherein, PSI5 is the PSI ID of NR system for carrying voice service; the PSI6 is a PSI ID of an NR system for carrying data traffic.

S49, the NR network device replies an MRU acceptance message to the terminal 10, wherein the MRU acceptance message is used for indicating that the SIM card 1 in the terminal 10 resides in an NR cell, and the MRU acceptance message indicates that the bearer of the voice service is in an activated state and the bearer of the data service is in a non-activated state.

Illustratively, the MRU accept message may be expressed as: registration accept with pdu session status PSI5 =1 and psi6=0.

S50, as no bearing channel for bearing data service exists on the NR network equipment, the problem of conference blocking occurs when the terminal 10 uses the SIM card 1 to carry out a conference.

After the NR network device receives the MRU registration request sent by the terminal 10, the NR network device may query the LTE network device for the context of the terminal 10. It is assumed that the bearer channel established by the terminal 10 on the LTE network device for carrying the data service cannot be transferred to the NR network device, so that the NR network device can only query the bearer for carrying the voice service from the LTE network device, i.e. PSI5 is in an active state and PSI6 is in an inactive state in the registration accept message. In this case, since there is no bearer channel for carrying data traffic on the NR network device, a problem of conference stuck occurs when the terminal 10 only uses the SIM card 1 for a conference.

S51, the terminal 10 sends PDU session establishment request to NR network equipment for requesting establishment of bearer for bearing data service.

Illustratively, the PDU session establishment request can be expressed as: PDU session establishment req.

S52, the NR network device replies to the terminal 10 with a PDU session accept message for indicating acceptance of the PDU session establishment request of the terminal 10, including a bearer for carrying the data traffic.

Illustratively, the PDU session accept message may be expressed as: PDU session establishment accept.

S53, the terminal 10 reconnects the conference (i.e. the conference reconnection) based on the bearer for carrying the data service allocated by the NR network device.

It should be noted that, in the scenario where the terminal 10 is currently operating in the DSDS mode, when the terminal 10 uses the SIM card 1 to perform a conference with the terminal 20, if the SIM card 1 of the terminal 10 receives a call from the terminal 30, the terminal 10 may also have a problem that the incoming call alert interface covers the conference interface, the conference is silent, the conference is blocked or interrupted, and the specific procedure may be referred to the above embodiment and fig. 4, which are not listed here.

In summary, in the related art, no matter whether the terminal 10 is currently operating in the DSDA mode or the DSDS mode, in the case where the terminal 10 uses the SIM card 1 to perform a conference with the terminal 20, no matter whether the SIM card 1 of the terminal 10 receives a call from the terminal 30 or the SIM card 2 of the terminal 10 receives a call from the terminal 30, there is a problem that the incoming call alert interface covers the conference interface, the conference is silent, the conference is blocked or interrupted.

In view of this, the embodiment of the application provides a processing method for receiving an incoming call in a conference, which can not only avoid the problem that the SIM card in the terminal causes interruption or blocking of the conference after receiving the incoming call in the process of conducting the conference, but also remind a user of an incoming call message on the premise of not affecting the voice transmission of the conference.

Specifically, in a scenario that the terminal currently works in a DSDS mode and one SIM card of the terminal enters a conference, the terminal is switched from the DSDS mode to the DSDA mode; in case the other SIM card of the terminal receives the call, the other SIM card of the terminal continues to camp in the current cell. Or under the scene that the terminal works in the DSDA mode currently and one SIM card of the terminal enters a conference, the terminal continues to work in the DSDA mode; in case the other SIM card of the terminal receives the call, the other SIM card of the terminal continues to camp in the current cell.

In addition, whether the terminal is currently operating in DSDS mode or DSDA mode, in the event that one SIM card of the terminal enters a conference and the SIM card receives a call, the SIM card continues to reside in the current cell.

The following will describe in detail a specific implementation procedure of a method for processing an incoming call received in a conference provided in an embodiment of the present application with reference to the accompanying drawings.

Fig. 5 is a flow chart of a processing method for receiving an incoming call in a conference, and as shown in fig. 5, the processing method may include the following steps.

S101, switching the terminal from a DSDS mode to a DSDA mode under the conditions that the terminal currently works in the DSDS mode, a first SIM card in the terminal resides in a cell of a first network system supported by the DSDS mode and the first SIM card enters a conference.

In some embodiments, in the case where the terminal is currently operating in the DSDS mode, a first SIM card in the terminal resides in a cell of a first network system supported by the DSDS mode, and a second SIM card in the terminal resides in a cell of a fourth network system supported by the DSDS mode.

The first network system and the fourth network system are one of a combination of systems of a DSDS mode supported by the terminal. For example, the first network system is a 5G system, and the fourth network system is a 4G system; or, the first network system is a 4G system, and the fourth network system is a 4G system.

In some embodiments, in the case where the terminal is currently operating in the DSDA mode, the first SIM card in the terminal resides in a cell of a second network system supported by the DSDA mode, and the second SIM card in the terminal resides in a cell of a third network system supported by the DSDA mode.

The second network system and the third network system are one of a combination of systems of DSDA modes supported by the terminal. For example, the second network system is a 5G system, and the third network system is a 5G system.

Also, for example, the second network system and the third network system are a combination of frequency bands supporting the DSDA mode corresponding to a combination of systems supporting the DSDA mode by the terminal. For example, the second network system is a 5G system, and the frequency band corresponding to the second network system is a first frequency band specified by a 5G protocol; the third network system is a 4G system, and the frequency band corresponding to the third network system is a second frequency band specified by the 4G protocol.

It should be noted that, in the embodiment of the present application, the first frequency band and the second frequency band are not specifically limited, and the actual setting is determined. It can be understood that, as long as the first frequency band and the second frequency band are a frequency band combination supporting the DSDA mode corresponding to the standard combination of the DSDA mode supported by the terminal, all belong to the protection scope of the embodiment of the present application.

In addition, it can be understood that the terminal displays the conference interface when the first SIM card in the terminal is conducting the conference. For example, the terminal may display a conference interface as shown in fig. 2 (1).

S102, a second SIM card in the terminal receives an incoming call request message (or called a first incoming call request message).

For example, the incoming call request message may be an invite message sent by other terminals (such as the terminal 30 described above, or other handsets) to the terminal for inviting the terminal to make a call. For example, the incoming call request message may be an invite message.

S103, the first SIM card in the terminal resides in a cell of a second network system supported by the DSDA mode, and the second SIM card resides in a cell of a third network system supported by the DSDA mode.

And S104, under the condition that the second SIM card receives the incoming call notification message, the terminal carries out incoming call reminding (or called first incoming call reminding) of the second SIM card, wherein the incoming call reminding comprises that the terminal displays an incoming call reminding interface, the incoming call reminding interface does not cover the conference interface, and the terminal does not ring.

In this embodiment, the first SIM card may be the SIM card 1, and the second SIM card may be the SIM card 2.

In the related art, when a terminal currently works in a DSDS mode, a first SIM card and a second SIM card in the terminal share a set of radio frequency resources; in the process that the first SIM card occupies radio frequency resources for meeting, when the second SIM card receives an incoming call, the second SIM card occupies the radio frequency resources used by the first SIM card when the meeting is carried out because the priority of the cellular telephone is highest, so that the first SIM card has no radio frequency resources available, and the meeting is blocked or interrupted. In addition, since the priority of the cellular phone is highest, after the second SIM card in the terminal receives the incoming call, the caller id display interface will cover the conference interface, and the terminal will switch the audio channel to the call, resulting in silence of the conference.

By adopting the scheme of the embodiment of the application, when the terminal currently works in the DSDS mode, the first SIM card resides in a cell of a first network system supported by the DSDS mode and enters a conference, the terminal is switched from the DSDS mode to the DSDA mode, so that the first SIM card and the second SIM card in the terminal respectively occupy a set of radio frequency resources; under the condition that the second SIM card receives the incoming call request message, the first SIM card resides in a cell of a second network system supported by the DSDA mode, a set of radio frequency resources is occupied for conference, and the second SIM card resides in a cell of a third network system supported by the DSDA mode, and a set of radio frequency resources is occupied for call, so that after the second SIM card receives an incoming call, the first SIM card is not influenced for conference, and the problem of conference blocking or interruption caused by the incoming call received in the conference can be solved.

In addition, under the condition that the second SIM card receives the incoming call notification message, the terminal carries out incoming call reminding of the second SIM card, and the incoming call reminding comprises that the terminal displays an incoming call reminding interface which does not cover a conference interface and the terminal does not ring, so that the problem that after the second SIM card receives an incoming call, the terminal is preempted in an audio channel, and the conference is silent can be solved.

In summary, by adopting the scheme of the embodiment of the application, the problem that the conference is interrupted or blocked after the second SIM card receives the incoming call in the conference process of the first SIM card in the terminal can be avoided, and the user can be reminded of the incoming call message on the premise that the conference voice transmission is not affected.

In some embodiments, the terminal may display the incoming call reminding interface through a floating window or a popup window, and meanwhile, the terminal may perform incoming call reminding through vibration, silence or flashing.

Illustratively, the first SIM card in the terminal displays a conference interface as shown in (1) of fig. 6 when a conference is conducted. After the second SIM card receives the incoming call, as shown in fig. 6 (2), the terminal displays an incoming call reminding interface in a floating window mode, and reminds the user of the incoming call in a vibration, mute or flash flashing mode. As shown in (2) in fig. 6, the incoming call reminding interface may include, for example, an incoming call number, an incoming call contact, and the like.

In some embodiments, as shown in fig. 6 (2), the incoming call alert interface also includes an "answer" button and a "hang-up" button. Responding to the operation of the user on the 'answer' button, and enabling the terminal to switch on the incoming call of the second SIM card; and responding to the operation of the hanging-up button by the user, and refusing the incoming call of the second SIM card by the terminal. In other embodiments, the terminal may also reject the incoming call of the second SIM card, i.e. slide reject, in response to a sliding operation of the incoming call alert interface by the user.

Fig. 7 is a flow chart of another processing method for receiving an incoming call in a conference, and as shown in fig. 7, the processing method may include the following steps.

S201, under the scene that the terminal currently works in a DSDA mode, a first SIM card in the terminal resides in a cell of a second network system supported by the DSDA mode and the first SIM card enters a conference, the terminal continues to work in the DSDA mode.

S202, a second SIM card in the terminal receives an incoming call request message (or called a first incoming call request message).

S203, the second SIM card in the terminal continues to reside in the cell of the third network system supported by the DSDA mode.

If the terminal does not start the voice transmission service corresponding to the third network system, the terminal starts and keeps starting the voice transmission service corresponding to the third network system, so that the second SIM card continues to reside in the cell of the third network system supported by the DSDA mode. If the terminal starts the voice transmission service corresponding to the third network system, the terminal keeps starting the voice transmission service corresponding to the third network system, so that the second SIM card continuously resides in a cell of the third network system supported by the DSDA mode.

For example, when the third network system is a 4G system, the voice transmission service is a VoLTE voice service. When the third network system is a 5G system, the voice transmission service is a VoNR voice service.

S204, under the condition that the second SIM card receives the incoming call notification message, the terminal carries out incoming call reminding (or called first incoming call reminding) of the second SIM card, wherein the incoming call reminding comprises that the terminal displays an incoming call reminding interface, the incoming call reminding interface does not cover the conference interface, and the terminal does not ring.

It should be noted that, for the illustration of S201-S204, reference may be made to the illustration of S101-S104 in the above embodiment, and the details are not repeated here.

In some embodiments of the present application, in a process that a terminal performs an online conference through a first SIM card, and in a case that an incoming call is received through a second SIM card, after the terminal connects the incoming call through the second SIM card, the terminal switches an audio channel to a call, so that the online conference performed by the terminal through the first SIM card is in a mute state.

In the related art, when a terminal currently works in a DSDA mode, and in the process of a conference carried out by a first SIM card, if a second SIM card does not start a VoNR function when the second SIM card receives an incoming call, the second SIM card is switched to a cell in a resident LTE system, so that the terminal is switched from the DSDA mode to the DSDS mode, that is, the first SIM card and the second SIM card share a set of radio frequency resources, thereby causing a conference to be blocked or interrupted. In addition, since the priority of the cellular phone is highest, after the second SIM card in the terminal receives the incoming call, the caller id display interface will cover the conference interface, and the terminal will switch the audio channel to the call, resulting in silence of the conference.

By adopting the scheme of the embodiment of the application, when the terminal works in the DSDA mode at present, the first SIM card resides in a cell of a second network system supported by the DSDA mode, and the first SIM card enters a conference, the terminal continues to work in the DSDA mode; under the condition that the second SIM card receives the incoming call request message, the second SIM card continuously resides in a cell of a third network system supported by the DSDA mode, and switching to cells of other network systems is avoided, so that the situation that after the second SIM card receives an incoming call, the first SIM card is not influenced to carry out a conference can be ensured, and the problem of conference blocking or interruption caused by the incoming call received in the conference can be solved.

Fig. 8 is a flow chart of another processing method for receiving an incoming call in a conference, and as shown in fig. 8, the processing method may include the following steps.

S301, the terminal currently works in a DSDA mode, a first SIM card in the terminal resides in a cell of a second network system supported by the DSDA mode, and the first SIM card enters a conference.

S302, the first SIM card in the terminal receives the incoming call request message (or called second incoming call request message).

S303, the first SIM card in the terminal continues to reside in the cell of the second network system supported by the DSDA mode.

If the terminal does not start the voice transmission service corresponding to the second network system, the terminal starts and keeps starting the voice transmission service corresponding to the second network system, so that the first SIM card continues to reside in the cell of the second network system supported by the DSDA mode. If the terminal starts the voice transmission service corresponding to the second network system, the terminal keeps starting the voice transmission service corresponding to the second network system, so that the first SIM card continuously resides in a cell of the second network system supported by the DSDA mode.

For example, when the second network system is a 4G system, the voice transmission service is a VoLTE voice service. When the second network system is a 5G system, the voice transmission service is a VoNR voice service.

S304, under the condition that the first SIM card receives the incoming call notification message, the terminal carries out incoming call reminding (or called second incoming call reminding) of the first SIM card, wherein the incoming call reminding comprises that the terminal displays an incoming call reminding interface, the incoming call reminding interface does not cover the conference interface, and the terminal does not ring.

It should be noted that, for the illustration of S301-S304, reference may be made to the illustration of S101-S104 in the above embodiment, and the details are not repeated here.

Fig. 9 is a flow chart of another processing method for receiving an incoming call in a conference, and as shown in fig. 9, the processing method may include the following steps.

S401, the terminal currently works in a DSDS mode, a first SIM card in the terminal resides in a cell of a first network system supported by the DSDS mode, and the first SIM card enters a conference.

S402, the first SIM card in the terminal receives an incoming call request message (or called a second incoming call request message).

S403, the first SIM card in the terminal continues to reside in the cell of the first network system supported by the DSDS mode.

If the terminal does not start the voice transmission service corresponding to the first network system, the terminal starts and keeps starting the voice transmission service corresponding to the first network system, so that the first SIM card continues to reside in the cell of the first network system supported by the DSDS mode. If the terminal starts the voice transmission service corresponding to the first network system, the terminal keeps starting the voice transmission service corresponding to the first network system, so that the first SIM card continuously resides in a cell of the second network system supported by the DSDS mode.

For example, when the first network system is a 4G system, the voice transmission service is a VoLTE voice service. When the first network system is a 5G system, the voice transmission service is a VoNR voice service.

S404, under the condition that the first SIM card receives the incoming call notification message, the terminal carries out the incoming call reminding (or called second incoming call reminding) of the first SIM card, wherein the incoming call reminding comprises that the terminal displays an incoming call reminding interface, the incoming call reminding interface does not cover the conference interface, and the terminal does not ring.

It should be noted that, for the illustration of S401 to S404, reference may be made to the illustration of S101 to S104 in the above embodiment, and the details are not repeated here.

In some embodiments of the present application, after the terminal receives the incoming call request, the terminal responds to the incoming call request to put through the first SIM card; in the communication process of the terminal through the first SIM card, the terminal can switch the conference to the second SIM card and continue the conference through the network signal provided by the second SIM card, so that the terminal does not influence the online conference in the communication process.

In the related art, in the process of a conference performed by the first SIM card, when the first SIM card receives an incoming call, if the first SIM card does not start the VoNR function, the first SIM card will switch to a cell in which the LTE system resides, and since a bearer channel used for carrying data services on the NR network device cannot be transferred to the LTE network device, after the terminal falls back from NR to LTE (i.e. EPSFB to LTE), the IP address of the bearer channel carrying data services is caused to be different, thereby causing a conference to be blocked or interrupted. In addition, since the priority of the cellular phone is highest, after the first SIM card in the terminal receives the incoming call, the caller id display interface will cover the conference interface, and the terminal will switch the audio channel to the call, resulting in silence of the conference.

By adopting the scheme of the embodiment of the application, when the terminal currently works in the DSDA mode, the first SIM card in the terminal resides in the cell of the second network system supported by the DSDA mode and the first SIM card enters the conference, the first SIM card continues to reside in the cell of the second network system supported by the DSDA mode when the first SIM card receives an incoming call, so that switching to the cell of other network systems is avoided. Correspondingly, when the terminal currently works in the DSDS mode and the first SIM card in the terminal resides in a cell of a first network system supported by the DSDS mode and the first SIM card enters a conference, when the first SIM card receives an incoming call, the first SIM card continues to reside in the cell of the first network system supported by the DSDS mode, so that switching to the cell of other network systems is avoided, the problem that the first SIM card is not influenced to conference after the first SIM card receives the incoming call, and conference blocking or interruption caused by the incoming call received in the conference can be solved.

In addition, under the condition that the first SIM card receives the incoming call notification message, the terminal carries out incoming call reminding of the first SIM card, and the incoming call reminding comprises that the terminal displays an incoming call reminding interface which does not cover a conference interface and the terminal does not ring, so that the problem that after the first SIM card receives an incoming call, the terminal is preempted in an audio channel, and the conference is silent can be solved.

In summary, by adopting the scheme of the embodiment of the application, no matter whether the terminal is currently operated in the DSDA mode or in the DSDS mode, the problem that the first SIM card in the terminal is interrupted or blocked after receiving the incoming call in the conference process can be avoided, and the user can be reminded of the incoming call message on the premise that the conference voice transmission is not affected.

Based on the above technical solution, in some embodiments of the present application, a terminal may set a conference mode, and when the terminal enters a conference under the condition that the conference mode is turned on, the above technical solution may be automatically executed. For example, as shown in (1) of fig. 10, the terminal may set a switch of the conference mode in the setting application, and in response to an opening operation of the conference mode by the user, as shown in (2) of fig. 10, the terminal opens the conference mode, that is, the switch of the conference mode is opened. Accordingly, in response to a closing operation of the user to the conference mode, the terminal exits the conference mode.

The specific implementation manner of the technical scheme is automatically executed after the terminal starts the conference mode is illustrated by the following with the accompanying drawings. It is to be understood that the following description is only one example of the present application and is not to be construed as limiting the embodiments of the present application. Of course, other specific implementation manners capable of implementing the above technical solutions should also belong to the protection scope of the embodiments of the present application.

Fig. 11 is a flowchart of a processing method for receiving an incoming call in a conference according to an embodiment of the present application, and an exemplary terminal may include a system UI (system interface), an audio module, and a Modem. The first SIM card and the second SIM card can share one Modem, and the first SIM card and the second SIM card can be controlled to reside in a cell of a system combination of DSDA modes supported by the terminal through the Modem. As shown in fig. 11, the processing method may include the following steps.

S501, when the terminal enters a conference, the system UI judges whether the terminal starts a conference mode.

If the terminal does not start the conference mode, the terminal does not execute the technical scheme provided by the embodiment of the application, and the terminal performs according to the scheme of the original conference flow. For example, the terminal does not perform S502-S505 and S512. If the terminal starts the conference mode, the terminal continues to execute the technical solution provided in the embodiments of the present application, e.g. the system UI continues to execute the following steps, e.g. S502.

S502, the system UI judges whether the terminal is connected with the network through a Wi-Fi access technology.

Here, the network refers to a network device, such as the above-described NR network device and LTE network device. If the terminal is connected to the network through the Wi-Fi access technology, the terminal continues to execute S503, but does not execute S504. If the terminal is not connected to the network through the Wi-Fi access technology, the terminal continues to S503 and to S504.

In addition, S502 may also be executed before S501, and the execution sequence of S501 and S502 is not limited in the embodiment of the present application.

In S502, if the terminal is connected to the network through the Wi-Fi access technology, the terminal may perform the conference through the Wi-Fi access technology, so that even if the terminal receives an incoming call in the conference, the terminal needs to fall back into a cell of other network systems, the smoothness of the conference is not affected, i.e. the problem of the conference being blocked or interrupted is not caused. In this case, in the embodiment of the present application, if the terminal is connected to the network through the Wi-Fi access technology, the terminal may not execute the technical solution provided in the embodiment of the present application, so that the purpose of reducing power consumption may be achieved.

S503, the system UI sends a first indication message to the audio module, wherein the first indication message is used for indicating the terminal to enter a conference mode.

S504, the system UI sends a first indication message to the Modem, and the first indication message is used for indicating the terminal to enter a conference mode, notifying the Modem to start VoNR voice services of the first SIM card and the second SIM card, and controlling the first SIM card and the second SIM card to reside in a cell of a 5G system.

Note that S504 may also be executed before S503, and the execution order of S504 and S503 is not limited in the embodiment of the present application.

It can be appreciated that in the embodiment of the present application, if the terminal is currently operating in the DSDS mode, it is required that the terminal is switched from the DSDS mode to operate in the DSDA mode; or if the terminal is currently working in the DSDA mode, the terminal is required to continuously work in the DSDA mode, and in this case, when the first SIM card in the terminal is in a conference, the second SIM card can solve the problem of conference blocking or interruption after receiving an incoming call. On the basis, the terminal is further required to start VoNR voice services of the first SIM card and the second SIM card, so that the problem that the first SIM card is in a conference and falls back to a cell in an LTE system after receiving an incoming call to cause conference blocking or interruption is solved, the terminal is prevented from currently working in a DSDA mode, the first SIM card is in the conference, and the second SIM card falls back to the cell in the LTE system after receiving the incoming call to cause the terminal to switch to the DSDS mode, and therefore the problem of conference blocking or interruption is solved.

Based on the above, by setting the conference mode, when the terminal starts the conference mode and enters the conference, the system UI may send a first indication message to the Modem, inform the Modem that the terminal has entered the conference mode currently, inform the Modem to start the VoNR voice service of the first SIM card and the second SIM card, and control the first SIM card and the second SIM card to reside in the 5G system cell. In addition, the system UI can also send a first indication message to the audio module to inform the Modem terminal that the conference mode is currently entered, so that when the terminal receives an incoming call in the conference, the audio module can not cut the call, and the conference is prevented from being soundless.

Therefore, when the terminal starts the conference mode and enters the conference, the terminal can solve the problem of conference blocking or interruption caused by receiving an incoming call in the conference with high probability by starting VoNR voice services of the first SIM card and the second SIM card in advance and controlling the first SIM card and the second SIM card to reside in a 5G system cell, namely controlling the terminal to work in the DSDA mode.

S505, the Modem controls the first SIM card to reside in a cell corresponding to a first frequency band supporting the DSDA mode in the 5G system, and controls the second SIM card to reside in a cell corresponding to a second frequency band supporting the DSDA mode in the 4G system, so that the terminal works in the DSDA mode currently.

It should be noted that, when the location of the terminal is updated, the situation that the 5G signal is weaker, but the 4G signal is stronger may occur, and because the SIM card of the terminal may choose to reside in the cell with strong network signal, in order to avoid that the SIM card in the terminal resides in the cell with 4G system, the terminal is switched from DSDA mode to operate in DSDS mode, so during the location update of the terminal, the Modem may execute S505 to ensure that the terminal currently operates in DSDA mode.

S506, the Modem receives an incoming call request message sent by the network and is used for requesting the terminal to carry out a call.

It should be noted that, in the case where the first SIM card enters the conference, if the other terminal (e.g., the terminal 30) calls the second SIM card, the network sends a paging message (i.e., a paging message) to the Modem. In the case where the first SIM card enters the conference, if another terminal (such as terminal 30) calls the first SIM card, the network sends an invite message to the Modem.

S507, the Modem receives conference data which is sent by a network and comprises voice data and video data.

And S508, the Modem sends the voice data to the audio module so that the audio module plays conference voice through a loudspeaker.

The audio module comprises a loudspeaker, the audio module receives the voice data and then transmits the voice data to the loudspeaker, and the loudspeaker converts the voice data into a voice signal and plays the voice signal.

S509, the Modem transmits the video data to the system UI so that the system UI displays the conference video.

S510, modem sends protocol (session initiation protocol, SIP) signaling to the network, including 183 session progress message/180 ringing message.

The incoming call information may include an incoming call of the SIM card 2, a phone number of the user a, and the like.

S511, the Modem sends an incoming call notification message to the system UI, including incoming call information.

S512, the system UI displays the incoming call information in a floating window/popup window mode based on the incoming call information so as to remind the user of the incoming call.

S513, the Modem sends an incoming call notification message to the audio module.

S514, the audio module judges whether the terminal starts a conference mode.

For example, if the terminal starts the conference mode, the audio module continues to play conference voice through the speaker, and performs incoming call reminding in a manner of vibration, silence or flashing light flashing, i.e. the terminal does not switch the audio channel to talk. If the terminal does not start the conference mode, the audio module plays the incoming call voice through the loudspeaker to carry out incoming call reminding, namely the terminal switches the audio channel to the call, so that the conference is silent.

It should be noted that, the order of executing the S511-S514 by the terminal is not limited in particular, and the terminal may execute the S513-S514 first and then execute the S511-S512.

In summary, in the embodiment of the present application, by setting the conference mode, when the terminal starts the conference mode and enters the conference, since the Modem starts the VoNR voice service of the first SIM card and the second SIM card, and controls the first SIM card and the second SIM card to reside in the 5G-mode cell, that is, controls the terminal to currently operate in the DSDA mode, the problem that the conference is blocked or interrupted due to the incoming call received in the conference can be solved with a high probability. In addition, the system UI carries out incoming call reminding in a floating window/popup window mode, and the audio module carries out incoming call reminding in a vibration, mute or flashing lamp flashing mode, so that the problems that an incoming call reminding interface covers a conference interface and the conference is silent can be solved.

S515, the system UI responds to the refusal operation of the user and sends refusal call information to the network through the Modem.

The reject call message (i.e., reject call) may be, for example, "Cancel, cause=user busy".

In some embodiments, a whitelist may be set in the Modem, where the whitelist includes incoming call information (e.g., phone number, name, etc.) of the non-rejected incoming call. For example, after the Modem receives the incoming call request message sent by the network, the Modem first determines whether the phone number corresponding to the incoming call is in the white list, if yes, the Modem continues to execute S510; if not, the Modem judges whether the terminal is currently operated in a DSDA mode or not, and judges whether VoNR voice services of the first SIM card and the second SIM card are started or not. If yes, the Modem continues to execute S510, if not, the Modem sends a refusal call message to the network, that is, "Cancel, cause=user busy".

Therefore, by setting the white list, if the telephone corresponding to the incoming call is not in the white list, the Modem in the terminal can directly reject the call message, so that the conference is not influenced.

In the case that the phone number corresponding to the incoming call is not in the white list, for example, in the case that the first SIM card of the terminal is in a conference, if the other terminal (such as the terminal 30) calls the second SIM card, the Modem determines whether the terminal is currently operating in the DSDA mode, and whether the second SIM card opens the VoNR voice service. If so, the Modem continues to execute S510, if not, the Modem ignores the paging message/invite message sent by the network (and sends "cancer, cause=user busy" to the network).

Under the condition that the first SIM card of the terminal is in the conference, if other terminals (such as the terminal 30) call the first SIM card, the Modem judges whether the second SIM card starts the VoNR voice service. If yes, the Modem continues to execute S510, if not, the Modem refuses the incoming call, and sends a "cancel user busy" to the network.

In some embodiments, after the terminal ends the conference (or the terminal exits the conference mode), the terminal resumes the previous settings, such as the terminal turning off the VoNR voice services of the first SIM card and the second SIM card, and exiting the DSDA mode.

It should be noted that, the above description is given by taking setting a white list in the Modem as an example, and of course, a blacklist may also be set in the Modem, where the blacklist includes incoming call information (such as a phone number, a name, etc.) that can reject an incoming call. Reference may be made to the above embodiments for specific implementation procedures, which are not described here in detail.

The external memory interface 120 may be used to connect an external memory card, such as a Micro SD card, to enable expansion of the memory capabilities of the electronic device. The external memory card communicates with the processor 110 through an external memory interface 120 to implement data storage functions. For example, audio, video, etc. files are stored in an external memory card.

The internal memory 121 may be used to store computer executable program code including instructions.

In addition, above the above components, the terminal 100 also runs an operating system, such as iOS operating system, android operating system, and the like. An operating application may be installed on the operating system.

The software system of the terminal 100 may employ a layered architecture, an event driven architecture, a micro-core architecture, a micro-service architecture, a cloud architecture, or the like. In this embodiment, taking an Android system with a layered architecture as an example, a software structure of the terminal 100 is illustrated.

Fig. 13 is a software configuration block diagram of a terminal according to an embodiment of the present application.

The layered architecture divides the software into several layers, each with distinct roles and branches. The layers communicate with each other through a software interface. In some embodiments, the Android system is divided into five layers, from top to bottom, an application layer, an application framework layer (framework), an Zhuoyun rows (Android run) and libraries, a hardware abstraction layer (hardware abstraction layer, HAL), and a kernel layer (kernel), respectively.

The application layer may include a series of application packages, among other things. The application package may include an APP for meetings, calls, calendars, videos, etc., and the application layer may also include a system UI for displaying interfaces of the terminal, such as a meeting interface, an incoming call alert interface, etc. By way of example, the system UI may display interfaces as shown in fig. 2 (1), fig. 2 (2), fig. 2 (3), fig. 10 (1), and fig. 10 (2).

The application framework layer provides an application programming interface (application programming interface, API) and programming framework for application layer applications. The application framework layer includes a number of predefined functions.

As shown in fig. 13, the application framework layer may include a window manager, a phone manager, an input manager, an activity manager, and the like.

Android runtimes include core libraries and virtual machines. Android run time is responsible for scheduling and management of the Android system.

The core library comprises two parts, wherein one part is a function to be called by java voice, and the other part is an android core library.

The application layer and the application framework layer run in a virtual machine. The virtual machine executes java files of the application program layer and the application program framework layer as binary files. The virtual machine is used for executing the functions of object life cycle management, stack management, thread management, security and exception management, garbage collection and the like.

The HAL may include a plurality of library modules, each of which may implement a set of interfaces for a particular type of hardware component, e.g., the HAL includes a display HAL, a camera HAL, an audio HAL, a sensor HAL, and so on. The kernel layer is a layer between hardware and software, and the kernel layer indication comprises display drive, camera drive, audio drive, sensor drive and the like.

In some embodiments of the present application, as shown in fig. 13, a message issued by the network may be sent to a Modem in the terminal through antenna hardware in the terminal, and then the Modem reports the message to an AP of the terminal.

Illustratively, during a conference at a terminal, the network transmits conference data, including voice data and video data, to a Modem in the terminal via antenna hardware in the terminal. And then, the Modem reports the voice data in the conference data to an audio module in the terminal, and the audio module plays conference voice through a loudspeaker. Accordingly, the Modem reports the video data in the conference data to the system UI in the terminal, and the system UI displays the conference video.

Also, for example, in the process that the other terminal calls the home terminal (i.e., the terminal), the network sends an incoming call request message to the Modem in the terminal through the antenna hardware in the terminal. The Modem then sends SIP signaling for obtaining incoming call information to the network through antenna hardware in the terminal, including 180 attempt message/183 session progress message.

Further, the network sends the incoming call notification message to the Modem in the terminal through the antenna hardware in the terminal. The Modem sends a call notification message to the audio module, and the audio module determines whether the audio channel needs to be switched to call; the Modem sends a call notification message to the system UI, and the system UI carries out call reminding.

The interface circuit 1102 may be, for example, an interface circuit between the processor 110 and an external memory; or as interface circuitry between the processor and the internal memory 121.

The processor 1101 and interface circuit 1102 may be interconnected by wires. For example, the interface circuit 1102 may be used to receive signals from other devices, such as the memory of the cell phone 100. For another example, the interface circuit 1102 may be used to send signals to other devices (e.g., the processor 1101). The interface circuit 1102 may, for example, read instructions stored in a memory and send the instructions to the processor 1101. The instructions, when executed by the processor 1101, may cause the terminal to perform the various steps performed by the first terminal in the embodiments described above. Of course, the chip system may also include other discrete devices, which are not specifically limited in this embodiment of the present application.
