Problems solved by technology

One type of multi-SIM wireless communication device, a multi-SIM multi-standby (MSMS) device, enables multiple SIMs to be in an idle mode waiting to initiate communication, but due to the sharing of a single radio frequency (RF) resource (e.g., transceiver), Thus only one SIM is allowed to participate in active communication at a time

Embodiment Construction

[0018] Various embodiments provide methods and devices for improving performance-optimized use of shared RF resources in a wireless communication device supporting at least one subscription through a VSIM application.

[0019] In MSMS devices that support virtual SIM operation, additional SIMs can be provisioned using a Virtual SIM (VSIM) application in which a subscription management system provides traditional subscription features similar to physical SIMs. Some VSIM management procedures, such as over-the-air communication with network infrastructure supporting VSIM authentication, are critical to the VSIM architecture as they are required to enable the VSIM application to perform normal SIM functions.

[0020] When there is contention for shared RF resources between the physical SIM and the VSIM loaded in the VSIM application, ordinary RF resource arbitration can be employed to resolve the conflict in communication scheduling. However, normal RF resource arbitration is gen...

Abstract

A method and apparatus for scheduling data packet transmissions on a multi-subscriber identity module SIM wireless communication device having at least a first SIM and a virtual SIM VSIM application associated with a shared radio frequency RF resource may include detecting (402) for a VSIM application registration of a SIM profile, wherein the VSIM application is set to operate as a VSIM; and determining (404) whether a VSIM management process is required for the VSIM. When a VSIM management procedure is required for a VSIM, the wireless communication device may tag (408) data packets associated with the required VSIM management procedure; select (416, 420) a prioritization strategy for data packet transmission on the RF resource; and The selected prioritization policy is applied (422) within the transmit queue on the RF resource.

Description

Background technique [0001] Multiple Subscriber Identity Module (SIM) wireless communication devices are becoming increasingly popular due to their flexibility in service options and other features. One type of multi-SIM wireless communication device, a multi-SIM multi-standby (MSMS) device, enables multiple SIMs to be in an idle mode waiting to initiate communication, but due to the sharing of a single radio frequency (RF) resource (e.g., transceiver), Thus only one SIM is allowed to participate in active communication at a time. Other multi-SIM devices may extend this capability to more than two SIMs, and may be configured with any number of SIMs greater than two (ie, a multi-SIM multi-standby wireless device). [0002] The SIM stores necessary setting data that allows the wireless communication device to communicate with the wireless communication network. A SIM may be a physical storage device in the form of a small smart card, such as a Universal Integrated Circuit Card...
