Example Embodiment

[0023] In the prior art, for existing multi-card multi-standby phones, such as LTE dual-card dual-standby phones, one of the SIM cards set as the primary card is used to provide data services and voice services, and the other is set as The SIM card of the secondary card is only used to provide voice services. Generally, in an LTE dual-card dual-standby mobile phone, the main card is in LTE network mode, and the secondary card is in GSM network mode. However, GSM networks are not supported in some areas, such as South Korea and Japan. When an LTE mobile phone is in an area without a GSM network, a SIM card that only provides voice services cannot provide voice services to users, which affects users' use.

[0024] In the embodiment of the present invention, the secondary card that provides the voice service is a multi-mode card, not just a 2G card. When the secondary card is performing the network search operation, it tries to reside in different network modes in sequence accordi...

Abstract

The invention discloses a multi-card multi-standby terminal and a method for realizing voice services thereof. The multi-card multi-standby terminal comprises a main card and at least one additional card, wherein the main card is suitable for providing the voice services and the data services for the terminal; and the at least one additional card is a multimode card and carries out network search according to preset network mode priority and provides the voice services after the additional card resides in a community and receives voice service requests. Through adoption of the multi-card multi-standby terminal and the method for realizing the voice services thereof, when a region where the multi-card multi-standby terminal is located does not support a GSM network, the voice services are still provided for a user.

Description

technical field [0001] The invention relates to the field of wireless communication, in particular to a multi-card multi-standby terminal and a method for realizing voice services. Background technique [0002] A dual-card dual-standby mobile phone refers to a mobile phone that can hold two SIM cards at the same time, and both SIM cards are in a standby state. [0003] At present, many mobile LTE mobile phones can support dual card dual standby. In a common dual-card dual-standby mobile phone, one SIM card is used to provide data services and voice services, and the other SIM card is only used to provide voice services. A SIM card that only provides voice services usually resides in a 2G network, for example, a GSM network. [0004] However, in practical applications, GSM networks are not supported in some regions, such as South Korea, Japan and other regions. When the LTE mobile phone is in an area without a GSM network, the SIM card that only provides voice services can...
