Abstract: A multi-subscriber identity module (SIM) wireless communication device performing early camping in initial cell selection or reselection may detect an active communication on a modem stack associated with a first SIM, and a condition requiring initial cell selection/reselection on a modem stack associated with a second SIM. In response to receiving a paging message for the second SIM, the wireless communication device may trigger a radio resource to tune to a frequency of an identified target cell of the second SIM, receive a first portion of system information broadcast by the identified target cell, and determine whether initial cell selection/reselection to the identified target cell is complete. In response to determining that initial cell selection/reselection to the identified target cell is not complete, the wireless communication device may save the received paging message, and raise a priority level for the activity on the modem stack associated with the second SIM.

Abstract: A method includes: receiving a first speech frame; identifying a first codec mode based at least in part on a Codec Mode Command (CMC) comprising the first speech frame; identifying a second codec mode based at least in part on a downlink (DL) Codec Mode Indication (DCMI) comprising the first speech frame; determining, based at least in part on a current uplink (UL) codec mode, to apply one of the first codec mode, the second codec mode, and a third codec mode having a higher bit rate than the first codec mode; and applying one of the first codec mode, the second codec mode, and the third codec mode. Apply the first codec mode when the RxLev and RXQual are determined not to exceed a predetermined threshold, and applying second or third codec modes otherwise.

Abstract: Various examples for performing remote authentication of a virtual subscriber identity module (SIM) on a multi-SIM, multi-standby communication device include receiving, on a first subscription of the multi-SIM, multi-standby communication device, an authentication request from a virtual SIM network. The multi-SIM, multi-standby communication device may respond to one or more acknowledgement requests sent from the virtual SIM network to the first subscription before tuning from the first subscription to a second subscription of the multi-SIM, multi-standby communication device to send the authentication request to a remote server. Upon receipt of the authentication response from the remote server through the second subscription, the multi-SIM, multi-standby communication device may send the authentication response to the virtual SIM network through the first subscription.

Abstract: A method is provided for implementing a local call hold in a dual subscription dual active first communication device. A first voice call may be established with a second communication device via a first communication network. An indication of a second voice call may be received from a third communication device via a second communication network. The first voice call may be placed on hold by sending a call hold indicator within a regularly transmitted frame to the second communication device. The second voice call may be established with the third communication device after placing the first voice call on hold. The first voice call with the second communication device may be subsequently resumed by excluding the call hold indicator from the regularly transmitted frame to the second communication device.

Abstract: Various embodiments implemented on a multi-subscription-capable communication device (e.g., a mobile communication device capable of supporting more than one wireless subscription) enable a data connection for a blanked subscription to be kept alive during transmit (Tx) blanking by ensuring at least one Packet Data Traffic Channel (PDTCH) transmission is sent to the network before the network's counter for PDTCH transmissions expires.

Abstract: Methods, systems, apparatuses, and devices are described for managing wireless communication at a user equipment (UE). An exemplary method includes adding an identifier of a cell to a sub-optimal cell list based at least in part on a cell classification determination made by the UE, and avoiding a cell access procedure for the cell based at least in part on inclusion of the identifier in the sub-optimal cell list. Another exemplary method includes maintaining a sub-optimal cell list and an associated priority service exception list, initiating a service on the priority service exception list, identifying inclusion of a cell on the sub-optimal cell list, where the cell is associated with a cell access procedure initiated for the service, and accessing the cell included in the sub-optimal cell list based at least in part on inclusion of the service in the priority service exception list.

Abstract: A method for performing a manual public land mobile network (PLMN) selection that includes: selecting an absolute radio frequency channel number (ARFCN) from an ARFCN set for one or more frequency bands supported by or enabled on a mobile communication device; determining whether the selected ARFCN is included in at least one allocation table of a first cell of a first PLMN; in response to determining that the selected ARFCN is not included in the at least one allocation table of the first cell of the first PLMN, adding the selected ARFCN to a second ARFCN set; and determining a PLMN identity (PLMN-ID) for each ARFCN in the second ARFCN set.

Abstract: A dual SIM dual active (DSDA) mobile station can perform a service acquisition procedure for a first subscription, while simultaneously performing a registration procedure for a second subscription. In one aspect of the disclosure, the RX (receive) of the victim during acquisition is delayed and yields to the TX (transmit) of the aggressor that is performing registration. In accordance with another aspect of the disclosure, decode failures on good cells due to RX blanking on the victim subscription during acquisition can be reduced or avoided.

Abstract: Methods and devices are disclosed for enabling improved performance on a single-transmit multi-SIM wireless communication device. The wireless communication device may detect a voice communication on a modem stack associated with the first SIM and a data communication on a modem stack associated with the second SIM. The wireless communication device may identify a data rate used by the voice codec to encode uplink traffic channel (TCH) bursts in the voice communication, and determine whether the identified data rate used by the voice codec permits TCH burst cancellation. If it is determined that the identified data rate used by the voice codec permits TCH burst cancellation, the wireless communication device may downgrade a portion of the uplink TCH bursts scheduled on the modem stack associated with the first SIM.

Abstract: Devices, systems, articles of manufacture, and methods for obtaining system information for a wireless communication device are described. According to some embodiments, a subscription supported by the wireless communication device enters a paging reorganization mode. The wireless communication device acquires a portion of system information by a first subscription using a radio frequency (RF) resource. The subscription changes a paging mode of the wireless communication device. The subscription releases the RF resource after acquiring the portion of the system information and prior to acquiring all of the system information. Other aspects, embodiments, and features are also claimed and described.

In response to determining that the first SUB control channel transmission would collide with the second SUB control channel transmission, the devices and methods alternate the first SUB control channel transmission and the second SUB control channel transmission to avoid collision.

Abstract: Access terminals capable of employing multiple subscriptions are adapted to prevent out-of-service periods for one or more subscriptions. According to one example, an access terminal can establish a data communication on a first subscription utilizing a first network, and an idle mode connection on a second subscription utilizing a second network. A determination can be made that the first subscription is indicating data transfer. In response to such a determination, the second subscription can attempt a change from a radio access technology associated with the second network to a different radio access technology. Other aspects, embodiments, and features are also included.
