Abstract

Methods, systems and devices are provided for controlling a communication device. Embodiments include receiving, through the transceiver, a voice call from a first network subscription associated with a first SIM of the communication device. The voice call may interrupt an active data services session through the transceiver with a second network subscription associated with a second SIM of the communication device. Also, embodiments include establishing an active voice communication connection for the voice call on the transceiver with the first network subscription. Additionally, reestablishing the active data services session through the transceiver with the first network subscription is performed while maintaining the active voice communication connection for the voice call with the first network subscription.

Description

Background technique [0001] Some wireless communication devices, such as smart phones, tablets, and laptops, contain more than one Subscriber Identity Module (SIM) that provides the user with access to a particular mobile phone network for each SIM card. Examples of mobile telephony networks include GSM, TDSCDMA, CMA2000 and WCDMA. A dual SIM wireless device is a wireless device that holds two SIM cards, which means that the device can handle two different network subscriptions. A different account number or phone number can be assigned to each web subscription. In a wireless device that includes only one transceiver, only one of the two subscriptions can transmit or receive radio frequency (RF) signals at the same time. Such devices are referred to as Dual SIM Dual Standby (DSDS) devices because while one subscription is actively transmitting or receiving, the other subscription is set to inactive. In contrast, in a wireless device called a Dual-SIM Dual-Access (DSDA) devi...
