Problems solved by technology

[0003] The problem with the existing technology is that, although both cards can access the LTE network in a dual-card dual-VoLTE terminal, because the current dual-card terminal is designed based on a single data link, only one user card can be configured at the same time as a user card. Data service card, another user card is actually a non-data service card

Embodiment 1

[0069] In the standby method of a dual-card terminal in an embodiment of the present invention, two user cards are configured in the terminal, which are respectively a data service card and a non-data service card, such as figure 1 shown, including:

[0070] Step 101: Detect the configuration mode switched between the data service card and the non-data service card, and select a standby strategy corresponding to the configuration mode.

[0071] Here, for different configuration modes, different standby strategies are adopted, which will be described in detail later.

[0072] Step 102, when the IMS voice service, ie VoLTE voice service, cannot be used through the non-data service card, directly park the non-data service card on the 2 / 3G network or reattach to the LTE network according to the standby policy.

[0073] In the embodiment of the present invention, the data service card can be set as the main card, and the non-data service card can be set as the secondary card, then...

Abstract

The invention discloses a standby method of a dual-card terminal and the terminal. Two subscriber cards, namely a data service card and a non data service card, are configured in the terminal. The method comprises that a configuration mode for switching between the data service card and the non data service card is detected, and a standby strategy corresponding to the configuration mode is selected; and when a VoLTE voice service cannot be used via the non data service card, the non data service card is resided in a 2 / 3G network directly or attached to the LTE network again according to the standby strategy.

Description

technical field [0001] The invention relates to a standby technology, in particular to a standby method and a terminal for a dual-card terminal. Background technique [0002] As far as the business of dual-card terminals is concerned, taking the long-term evolution (LTE, Long Term Evolution) scenario as an example, the dual-card models of LTE terminals have exceeded 96% of the market share, and have won the general recognition of the market and consumers. VoLTE network is a voice service based on IP Multimedia System (IMS, IP Multimedia Subsystem), which is called LTE voice. It uses IP data transmission technology and does not need 2G / 3G network. All services are carried on 4G network, which can realize data Unification with the voice service under the same network. In order to make full use of the service characteristics of VoLTE full Internet service (PS), PS can also be called data service, and currently needs a dual-card terminal solution with VoLTE function, so that LT...
