AI Technical Summary

Problems solved by technology

Such a failure may result in a mismatch between the downlink mode of the wireless communication device and the corresponding downlink mode in the network
While this mismatch can be resolved by performing a cell update procedure, such a procedure may involve inefficient use of power and / or network resources, as well as degrade performance for active communications

Embodiment Construction

[0021] Various embodiments will be described in detail with reference to the accompanying drawings. Wherever possible, the same reference numbers will be used throughout the drawings to refer to the same or like parts. References made to particular examples and implementations are for illustrative purposes, and are not intended to limit the scope of the invention or the claims.

[0022] Various embodiments provide methods, systems, and devices that improve the performance of wireless devices configured to communicate over multiple SIMs using shared RF resources. In particular, various embodiments may avoid call performance degradation on a first SIM by identifying and correcting missed downlink control signals during tune away to a network associated with a second SIM.

[0023] In some embodiments, at least one SIM of the MSMS wireless communication device may be associated with High Speed ​​Packet Access (HSPA) and may support multiple modes for High Speed ​​Downlink Packet ...

Abstract

Methods and apparatus for improving the performance of a wireless communication device having at least a first Subscriber Identity Module (SIM) and radio frequency (RF) resources may include detecting, on a modem stack associated with the first SIM, that supports high speed downlink Active communication in the first network for packet access (HSDPA). During active communication in the first network, the wireless communication device may detect a signal interruption period and determine whether the operational downlink mode for the modem stack associated with the first SIM does not correspond to that indicated in the first network. The downlink pattern matches. When determining that the operational downlink mode for the modem stack associated with the first SIM does not match the corresponding downlink mode represented in the first network, the wireless communications device may trigger a transition to a new downlink mode. internal instructions in road mode.

Description

[0001] related application [0002] This application claims priority to U.S. Provisional Application No. 62 / 259,953, filed November 25, 2015, entitled "System and Methods for Avoiding Call Performance Degradation due to Missed Downlink Control Signalin a Wireless Communication Device," which is hereby incorporated by reference The entire content of the above application is incorporated herein. Background technique [0003] Multiple Subscriber Identity Module (SIM) wireless communication devices have become increasingly popular due to their flexibility in service options and other features. One type of multi-SIM wireless communication device (Multi-SIM Multiple Standby (MSMS) device), such as a Dual-SIM Dual-Standby (DSDS) device, enables two SIMs to wait in idle mode to initiate communication, but due to the need for a single radio ( RF) resources (eg, transceivers) are shared, thus allowing only one SIM to participate in active communications at a time. Other multi-SIM devi...
