Detailed Description

For the purpose of making the objects, technical solutions and advantages of the embodiments of the present invention more apparent, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings, and it is apparent that the described embodiments are some embodiments of the present invention, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.

At present, under the conditions of few base stations and weak signals in remote areas, the IMS terminal cannot ensure the stability of IMS call service, and the daily communication of users is affected.

Based on this, the embodiment of the invention provides a call switching method and device for terminal equipment, electronic equipment and storage medium, and particularly provides a call switching method for an IMS terminal, so as to improve the call stability of the IMS terminal.

For the convenience of understanding the present embodiment, a call switching method of a terminal device disclosed in the embodiment of the present invention is first described in detail.

Embodiment one:

The embodiment of the invention provides a call switching method of terminal equipment, referring to a flow chart of the call switching method of the terminal equipment shown in fig. 1, the call switching method of the terminal equipment comprises the following steps:

Step S102, after the terminal equipment is successfully registered in the first network, the terminal equipment initiates a call through the first network.

The terminal device in this embodiment may be an IMS terminal, where the IMS terminal may register the first network successfully first, and then initiate a call through the first network.

Step S104, if the call meets the preset switching condition, the terminal equipment registers the second network.

In this embodiment, before the call ends, a certain time may be set at intervals, so as to determine whether a call meets the switching condition. The first network in this embodiment may be different networks, and the switching conditions of the different networks may be the same or different, which is not limited in this embodiment.

If the call satisfies the switching condition of the first network, it indicates that the terminal device needs to perform network switching at this time, and the terminal device may register a second network different from the first network. If the call does not meet the switching condition of the first network, the terminal equipment does not need to switch the network at the moment, and the terminal equipment can keep registering the first network.

In step S106, if the network bearers of the first network and the second network are the same, the terminal device keeps talking.

If the network bearers of the first network and the second network are the same, the first network and the second network can be confirmed to have the same IP addresses, and at the moment, the terminal equipment can keep talking, so that network switching in the talking process is completed.

The embodiment of the invention provides a call switching method of terminal equipment, which is characterized in that after the terminal equipment is successfully registered in a first network, the terminal equipment initiates a call through the first network; if the call meets the preset switching condition, the terminal equipment registers a second network; if the network bearers of the first network and the second network are the same, the terminal device keeps talking. In this way, the call stability of the IMS terminal can be improved.

Embodiment two:

The present embodiment provides another call handover method of a terminal device, where the method is implemented based on the foregoing embodiments, and in some embodiments, the first network is an LTE (Long Term Evolution ) network, and the second network is a VoWIFI (Voice over WiFi, voice over IP service performed based on a WiFi network) network; or the first network is VoWIFI networks and the second network is an LTE network. Among them, LTE is a mobile communication technology, which is one of fourth generation (4G) wireless communication standards.

If the first network is an LTE network and the second network is a VoWIFI network, in this embodiment, handover from the LTE network to the VoWIFI network may be implemented; if the first network is VoWIFI and the second network is an LTE network, the handover from VoWIFI to LTE can be implemented in this embodiment.

Based on the above description, referring to a flowchart of another call switching method of a terminal device shown in fig. 2, the call switching method of the terminal device includes the steps of:

Step S202, after the terminal equipment is successfully registered in the first network, the terminal equipment initiates a call through the first network.

In this embodiment, the switching from the LTE network to the VoWIFI network is illustrated, and a schematic diagram of switching from the LTE network to the VoWIFI network may be referred to as shown in fig. 3. The IMS terminal initiates registration, establishes LTE IMS APN (Access Point Name ) network bearers, and the registration is successful.

Wherein the APN is a parameter for a mobile network that allows the mobile device to connect to the operator's data network. Each operator has its own APN setting for configuring the device to access its specific mobile data network. IMS APN configuration allows the mobile device to connect to the operator's IMS network in order to use IMS services.

As shown in fig. 3, the IMS terminal may establish a call after registering with the LTE network.

In step S204, if the call satisfies the preset handover condition, the terminal device registers the second network.

In some embodiments, the above-described switching conditions include: the call has no sound or network change.

As shown in fig. 3, the terminal detects that the call satisfies the preset condition if it is detected that there is no sound or the network is changed. At this point, the terminal device may initiate registration, establish an EPDG (Evolevd PACKET DATA GATEWAY, evolved packet data gateway/evolved packet data gateway) network bearer, and the registration is successful.

The main function of the EPDG channel is to transfer VoWIFI voice data from the mobile device to the IMS network and to transfer voice data from the IMS network back to the mobile device. The EPDG path connects to the mobile device through the WIFI network and communicates with other elements in the IMS core network, such as S-CSCF (SERVING CALL Session Control Function) and P-CSCF (Proxy Call Session Control Function).

In step S206, if the network bearers of the first network and the second network are the same, the terminal device keeps talking.

As shown in fig. 3, the IMS terminal may monitor LTE IMS APN network bearers and VoWIFI EPDG network bearers for identity. If the network bearers of the first network and the second network are the same, the terminal equipment keeps talking.

Step S208, if the network load of the first network is different from the network load of the second network, the terminal equipment carries out call renegotiation; the terminal equipment determines the result of the call renegotiation.

As shown in fig. 3, if LTE IMS APN network bearers and VoWIFI EPDG network bearers are different, the network bearers of the first network and the second network are different, the IMS terminal may send Reinvite or UPDATE renegotiation and determine the result of the call renegotiation.

In some embodiments, the terminal device maintains the call if the result of the call renegotiation indicates that the call is restored to normal.

As shown in fig. 3, if the result of the call renegotiation indicates that the call is restored to normal, the IMS terminal may hold the call, thereby completing call handover of the IMS terminal.

In some embodiments, if the result of the call renegotiation indicates that the call has not been restored, the terminal device hangs up the call.

As shown in fig. 3, if the result of the call renegotiation indicates that the call is not restored to normal, the IMS terminal cannot hold the call, and at this time, the IMS terminal may hang up the call.

In some embodiments, the terminal device may also re-register the second network.

As shown in fig. 3, after the IMS terminal can hang up the call, re-registration can be performed: i.e. re-registering the second network, ensuring the stability of the IMS service.

The above method provided by the embodiment of the present invention is illustrated by switching from the LTE network to the VoWIFI network: the IMS terminal may actively switch the network bearer to the registration of VoWIFI networks when call silence occurs or the LTE network is changed after the LTE network registration is successful. If the network load is not changed, the communication can be kept; if the network load is changed, the renegotiation can be tried to restore the call; and according to the renegotiation result, selecting to hang up the call to execute IMS re-registration or hold the call.

The method provided by the embodiment of the present invention may be applied to the scenario of switching from the VoWIFI network to the LTE network, in addition to the scenario of switching from the LTE network to the VoWIFI network, which is not described in detail in this embodiment.
