Description

Call initiating method and electronic equipment

Technical Field

The present application relates to the field of communications, and in particular, to a call initiation method and an electronic device.

Background

In the communication field, if a New Radio (NR) supports an IP Multimedia Subsystem (IMS) service, an electronic device may initiate call initiation based on an IMS network in a Voice over NR (VoNR) manner based on the NR, and similarly, if a Long Term Evolution (LTE) network supports the IMS service, call initiation may be initiated based on the IMS network in a Voice over LTE (VoLTE) manner based on the LTE. Because NR belongs to a PS ONLY network and does not support dual-domain registration of CS/PS, a call can ONLY be carried out in a VoNR network, when VoNR fails to initiate, the electronic equipment is instructed to be switched to a nearby LTE network through reselection or redirection to continue to initiate the call in a VoLTE mode, and if VoLTE also fails to initiate, the electronic equipment is instructed to be switched to a nearby 2/3G network through reselection or redirection to continue to initiate the call. According to the 3GPP protocol, NR only supports interworking with LTE, and the 3GPP protocol does not specify interworking between NR and 2/3G networks. Because the LTE core network supports CS/PS dual-domain registration (i.e. supports an interface connected to the 2/3G core network), and the NR core network does not support the capability of call origination falling back to the 2/3G network, the NR network indicates to redirect to the LTE network to attempt to originate a call, and the call origination fails and then falls back to the 2/3G network.

If the NR network does not support the IMS and the current position of the electronic equipment does not have the LTE network, the electronic equipment needs to fall back to the LTE network after initiating a call through the NR network, and the call initiation fails because the LTE network cannot be searched; if the NR network supports the IMS service but the LTE network does not support the IMS service, after the electronic device initiates a call to establish a VoNR call, the electronic device moves to an area without the NR network but with the LTE network, and a Packet Service Handover (PSHO) call handover cannot be performed due to the fact that the LTE network does not support the IMS service, so that a call drop occurs.

Wherein the first order C_3GThe number of successful calls through the 2G/3G network; second number of times C_NRBased on the number of new wireless NR network call failures.

Judging whether the electronic equipment works in an SA mode currently; if the electronic equipment works in the SA mode currently, judging whether the timer runs or not; if the timer is running, the electronic equipment starts a call priority module to start a priority call function of the electronic equipment; if the timer is not running, judging whether the call state of the electronic equipment is origining; if the call state of the electronic equipment is Originating, acquiring a service state indication message and a call state indication message reported by a bottom layer, and determining whether the NR service is normal according to the service state information reported by the bottom layer; when the server state information indicates that the NR service is normal, the call state indication information indicates that the call state is failure, and the network type is NR network, it indicates that the call on the NR network cannot be successful, and order C_NR＝C_NR+ 1; if the call state is alerting, C is reset_3GAnd C_NR。

Further, when the service status indication message indicates that the NR service is normal and the LTE service is not normal, if the call status indication message indicates that the call status is failure, the C is enabled_NR＝C_NR+ 1; if the call state is alerting, C is reset_3GAnd C_NR。

When the service state indication message indicates that the NR service is normal and the call state information indicates that the call state is alerting, indicating that the call on the NR cannot be successful; the electronic equipment is switched to the LTE network from the NR network, acquires service state indication information and call state indication information reported by a bottom layer, if the service state indication information indicates that the LTE service is normal and the call state indication information indicates that the call state is alerting, the electronic equipment indicates that the call on the LTE network cannot be successfully called, and switches to the 2G/3G network from the LTE networkWhen the current network standard is determined to be a 2G/3G network, order C_3G＝C_3G+ 1; if the current network type is not the 2G/3G network, resetting the C_3GAnd C_NR；

In one example, when the received service status indication message indicates that both NR and LTE are out of service, the electronic device does not perform any processing for any call status indicated by the received call status indication message.

Specifically, when C_3GGreater than or equal to a first threshold, or C_NRAnd when the second threshold value is greater than or equal to the second threshold value, the electronic equipment starts the call priority module so as to start the priority call function of the electronic equipment.

Wherein, the first threshold and the second threshold can be the same or different.

Alternatively, the first threshold may be 1, 2, 3, 4 or other values; the second threshold may be 1, 2, 3, 4 or other values.

After the call priority module is started, the call priority module starts to monitor a call request issued by an upper layer; when a call request issued by an upper layer is monitored, the call priority module executes switching to a 2G/3G network operation; if the call is not switched to the 2G/3G network or the call based on the 2G/3G network fails to be initiated, C is reset_3GAnd C_NR(ii) a If the network is switched to the 2G/3G network, initiating a call on the 2G/3G network; searching network again after the call priority module finishes the call to access NR network and order C_prio＝C_prio+1. Specifically, when the call priority module searches for a new network to access the NR network, a timer is started to start timing, and the timing duration of the timer and the number of times C that the priority start module is started are set_prioIn a positive relationship, let C_prio＝C_prio+ 1; after the timer is over time, the call priority module is closed toStopping searching network, stopping timer, resetting C_3GAnd C_NR。

It should be noted that, when the electronic device detects that the timer is running, the electronic device directly activates the call priority module of the electronic device to start the priority call function of the electronic device.

After the call is successful on the 2G/3G network, in order to ensure the data service of 5G, the network is searched again to access the NR network; starting a timer to ensure that the priority call function is started, thereby continuously monitoring a call request issued by an upper layer, wherein the monitoring time is the time of the timer; by counting the opening times C of the calling priority module_prioThe number of times that the electronic equipment needs to make calls within a period of time can be estimated, and the number of times C of opening the electronic equipment_prioThe larger the number of calls the electronic device needs to make, the longer the listening period, i.e. with the number of on-times C, is set_prioThe larger the time, the longer the timer is, the longer the time is, so as to ensure the call success, and improve the adaptability of special scenes.

In one example, when the third threshold is exceeded, C is reset_3G、C_NRAnd C_prio。

In one example, the timing duration D of the timer_3G＝C_prioT, wherein T is a preset duration.

In one example, when the electronic device reboots or enters flight mode, reset C_3G、C_NRAnd C_prio。

In one possible embodiment, after monitoring the call request, the electronic device automatically performs switching to the 2G/3G network operation; optionally, after monitoring a call request of a call upper layer, popping up a prompt box on a display interface of the electronic device, wherein the prompt box is used for prompting a user whether to switch to a 2G/3G network; after receiving a confirmation instruction of the user for the prompt box, the electronic device performs switching to a 2G/3G network operation, wherein the confirmation instruction may be a touch instruction, a gesture instruction, a voice instruction or other instructions. As shown in a diagram in fig. 4, the confirmation command is a touch command.

Optionally, as shown in a b diagram in fig. 4, after a call request of a call upper layer is monitored, a first prompt box and a second prompt box pop up on a display interface of the electronic device, where the first prompt box displays "switch to 2G network" for prompting a user to switch to the 2G network, and the second prompt box displays "switch to 3G network" for prompting the user to switch to the 3G network; if the confirmation instruction of the user for the first prompt box is received, the electronic equipment executes the operation of switching to the 2G network; if the confirmation instruction of the user for the second prompt box is received, the electronic equipment executes the operation of switching to the 3G network; the confirmation instruction may be a touch instruction, a gesture instruction, a voice instruction, or other instruction. As shown in fig. 4 b, the confirmation command is a touch command.

In a specific scene, in the initial stage of 5G construction, a 5G network does not support VoNR service, and a blind area exists in LTE network coverage or a VoLTE service probability fault occurs; when the electronic equipment is positioned in the area, the electronic equipment can be accessed to a 2G/3G network, an LTE network and a 5G network; the user dials a call through the electronic equipment, at the moment, the network accessed by the electronic equipment is a 5G network, the service state indicating message indicates that NR service is normal, but the call state indicating message indicates that the call state is alerting because the 5G network does not support VoNR service, and the electronic equipment cannot initiate a call in the 5G network; the electronic equipment is switched to the LTE network, and the service state indication message indicates that the LTE service is normal; however, because a blind area exists in the coverage of the LTE network or the VoLTE server fails, the call state indication message indicates that the call state is alerting, and the electronic device cannot initiate a call on the LTE network; the electronic equipment is switched to the 2G/3G network, and after the 2G/3G network completes the call, the C is enabled_3G＝C_3G+1；

When the user makes a call again through the electronic device, the above operation is repeatedly performed.

At C_3GIf the number is larger than 3, the user makes a call through the electronic equipment, and the electronic equipment starts a priority call function; the electronic equipment monitors a call request issued by an upper layer; when a call request issued by an upper layer is monitored, switching to a 2G/3G network operation is executed; if not switched to the 2G/3G network or the call based on the 2G/3G networkIf the initiation fails, C is reset_3G(ii) a If the network is switched to the 2G/3G network, initiating a call on the 2G/3G network; and searching the network again after the call is ended to access the 5G network to ensure that the 5G data service is normally used.

In another specific scenario, a 2G/3G network is built in a specific region, an LTE network is not built for historical reasons, and a 5G network is built in the region; when the electronic equipment is located at the place, the networks which can be accessed by the electronic equipment are a 2G/3G network and a 5G network, a user makes a call through the electronic equipment, the network which the electronic equipment is accessed to is the 5G network at the moment, the service state indication message indicates that NR service is normal, but because the 5G network does not support VoNR service in the initial construction stage, the call state indication message indicates that the call state is failure, the electronic equipment cannot initiate a call in the 5G network, and no LTE network exists nearby, so that the call fails, and C is enabled to be connected to the network_NR＝C_NR+1；

Repeatedly performing the above operations when C_3GIf the number is more than 3, the calling is not successful even if the operation is repeated for 3 times, and the electronic equipment starts a priority calling function; the electronic equipment monitors a call request issued by an upper layer; when a call request issued by an upper layer is monitored, 2G/3G manual network searching is executed; if the call initiation fails for switching to the 2G/3G network or based on the 2G/3G network, resetting C_NR(ii) a If the network is switched to the 2G/3G network, initiating a call on the 2G/3G network; and searching the network again after the call is ended to access the 5G network to ensure that the 5G data service is normally used.

It can be seen that, in the solution of the present application, under the condition that the coverage of the NR network and the LTE network is incomplete, or the IMS network is not supported, by counting the number of times of call failure based on the NR network, or the number of times of call success based on the 2G/3G network, when the number of times of call failure based on the NR network, or the number of times of call success based on the 2G/3G network exceeds a preset value, the electronic device directly switches to the 2G/3G network to complete the call, thereby solving the problem of call failure or call drop under the condition that the coverage of the NR network and the LTE network is incomplete, or the IMS network is not supported. Meanwhile, the situation that NR and LTE networks cannot call for a long time is dealt with, the time length of the timer is adaptively increased, and the effect of improving the call success probability under a specific scene is achieved.
