CROSS-REFERENCE TO RELATED APPLICATION

This application claims the benefit of Korean Patent Application No. 10-2018-0123929, filed on Oct. 17, 2018, in the Korean Intellectual Property Office, the disclosure of which is incorporated herein by reference in its entirety.

TECHNICAL FIELD

This disclosure relates generally to wireless communication, and more particularly, to a method and device for multi-Subscriber Identify Module (SIM) wireless communication.

DISCUSSION OF THE RELATED ART

Wireless communication using multi-SIM may enable a wireless terminal to connect two different network services. For example, the terminal may include a plurality of SIMs, e.g., by means of a plurality of SIM cards inserted therein, where the plurality of SIMs may respectively correspond to different subscribers and/or telephone numbers. The terminal may implement a plurality of protocol stacks to drive a plurality of wireless communications corresponding to the plurality of SIMs. When the plurality of protocol stacks in the terminal mutually exclusively use a radio frequency (RF) resource, wireless communication derived by some of the protocol stacks may be inevitably suspended. For instance, during a voice or data call associated with a first SIM, it may be desirable to periodically listen for an incoming page associated with a second SIM. However, this often results in the ongoing call becoming periodically suspended to handle the page, resulting in possible degradation of communication quality or loss of information.

SUMMARY

Embodiments of the inventive concept provide a device and a method of simultaneous reception in multi-Subscriber Identify Module (SIM) wireless communication.

According to an aspect of the inventive concept, there is provided a method of multi-Subscriber Identify Module (SIM) wireless communication, the method including: establishing a window for at least receiving paging in an idle state of a first wireless communication associated with a first SIM. A prediction is made, based on the window, of a collision or non-collision between the paging and a second wireless communication associated with a second SIM. It is then determined, in response to a collision prediction, whether a simultaneous reception of the paging and the second wireless communication is possible through use of different respective carrier waves, and if so, respective radio frequency (RF) paths are allocated to the paging and the second wireless communication, where the allocated RF paths correspond to the different respective carrier waves.

According to an aspect of the inventive concept, there is provided a method of multi-Subscriber Identify Module (SIM) wireless communication, the method including: obtaining radio frequency (RF) resource information regarding configurations of carrier aggregation and/or multi-connectivity; determining, based on the RF resource information, whether a simultaneous reception of a paging of a first wireless communication associated with a first SIM, and, a second wireless communication associated with a second SIM is possible; if so, allocating respective RF paths to the paging and the second wireless communication, where the allocated RF paths correspond to different carrier waves.

According to an aspect of the inventive concept, there is provided a Multi-SIM Multi-Standby (MSMS) device including a memory, and at least one processor configured to perform either of the above-summarized multi-Subscriber Identify Module (SIM) wireless communication methods by executing instructions stored in the memory.

According to an aspect of the inventive concept, there is provided a user equipment supporting an MSMS device, the user equipment including a first Subscriber Identify Module (SIM), a second SIM, a transceiver generating a plurality of radio frequency paths corresponding to a plurality of carriers, and a multi-SIM device connected to the transceiver, the first SIM, and the second SIM. The multi-SIM device may include a processor configured to execute instructions to determine whether a simultaneous reception of a first paging of a first wireless communication associated with the first SIM, and, a second wireless communication associated with the second SIM is possible through use of different respective ones of the carrier waves; and allocate, in response to a determination that the simultaneous reception is possible, at least one RF path from among the plurality of RF paths to each of the first paging and the second wireless communication.
