Problems solved by technology

In addition, the drop rate of 2G and 3G occurs from time to time, but the drop rate of VoLTE is close to zero
[0003] However, in the current environment, there are many operators whose VoLTE voice services are not yet commercially available. For most dual-card phone users, a mobile phone can only have one SIM (Subscriber Identity Module, also known as subscriber identity identification) The card uses LTE, and the other SIM card uses GSM or WCDMA. At this time, if the network of the other card supports VoLTE, then VoLTE voice services cannot be used when making calls, and only traditional voice methods can be used.
Moreover, users generally do not know whether the current network environment supports VoLTE, so they can only try to register, which leads to poor user experience.

Embodiment 1

[0023] Please refer to figure 1 , which shows a flow chart of a method for switching a call network by a dual-card terminal provided in Embodiment 1 of the present invention. The method for switching a call network by a dual-card terminal can be used in a mobile terminal, and the method for switching a call network by a dual-card terminal includes Follow the steps below:

[0024] Step 101: Determine whether the first user identification card supports VoLTE. If the first user identification card does not support VOLTE, proceed to step 102.

[0025] Wherein, the first user identification card is currently set to connect to the LTE network.

[0026] Optionally, judging whether the first user identification card supports VoLTE includes:

[0027] When the first user identification card has been registered on the LTE network, determine whether the first user identification card can register with the IMS network, if yes, the first user identification card supports VoLTE, otherwise ...

Embodiment 2

[0036] Please refer to figure 2 , which shows a flow chart of a method for switching a call network by a dual-card terminal provided in Embodiment 1 of the present invention. The method for switching a call network by a dual-card terminal can be used in a mobile terminal, and the method for switching a call network by a dual-card terminal includes Follow the steps below:

[0037] Step 201: Determine whether the first user identification card supports VoLTE. If the first user identification card does not support VOLTE, proceed to step 202.

[0038] Wherein, the first user identification card is a user identification card currently configured to connect to a 4G network, that is, the first user identification card is set in the terminal to be connected to a 4G network or in a 4G priority mode. In a dual-card terminal, generally one user identification card is connected to the 4G network, and the other user identification card is set to be connected to 2G or 3G at this time. Wh...

Abstract

The invention discloses a method and a device for switching conversation networks of a double-card terminal. The method comprises steps that, whether a first user identity identification card supports VoLTE is determined, and the first user identity identification card is set to be connected with the LTE network; if the first user identity identification card does not support VoLTE, whether a second user identity identification card supports VoLTE is determined; if the second user identity identification card supports VoLTE, the second user identity identification card is connected with the LTE network. According to the method and the device for switching the conversation networks of the double-card terminal, whether the two user identity identification cards support VoLTE is determined, the user identity identification card supporting VoLTE is automatically selected to be connected with the LTE network, and thereby a user can realize VoLTE noise conversation.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to a method and device for a dual-card terminal to switch call networks. Background technique [0002] VoLTE (Voice over LTE) is a voice service based on IMS (IP Multimedia Subsystem, IP Multimedia Subsystem), which is a voice service standard at the control and media level of LTE (Long Term Evolution, Long Term Evolution). IMS has become the core network standard architecture in the all-IP era because it supports multiple access and rich multimedia services. The most direct experience VoLTE technology brings to 4G (the 4th Generation mobile communication, fourth-generation mobile phone mobile communication standard) users is the shorter waiting time for connection, and higher quality and more natural audio and video call effects. VoLTE is fundamentally different from 2G (the 2nd Generation mobile communication, second-generation mobile communication standard) and 3G (the 3r...
