Abstract: Methods, devices, and systems embodiments enable management of service preemption of at least one of a plurality of subscriptions that utilize a plurality of radio-frequency (RF) chains on a multi-Subscriber-Identity-Module, multi-active communication device in a manner that can accommodate a variety of different RF hardware components and configurations. Various embodiments provide methods implemented by a processor to manage service preemption. In response to detecting that a service of a second subscription initiated on a first RF chain is or will preempt a service of a first subscription that is also serviced by the first RF chain, the processor may determine whether there is a similar service on a second RF chain that may be used as a substitute for the first subscription's preempted service and, when available, the processor may configure the first subscription to begin utilizing the substitute service until the first RF chain is available.

Abstract: Methods and devices are disclosed for enabling efficient network registration using a shared radio resource for at least a first and second SIM of a multi-SIM wireless communication device. After the end of a radio-off condition of the radio resource, the wireless device may identify services supported by each of the first and second SIMs, evaluate criticality of the supported services, determine which of the first and second SIM supports the service having the highest criticality, and prevent the other SIM from registering with its network before the SIM with the service of the highest criticality has successfully registered for service in its selected network.

Abstract: To leverage the potential advantages of configuring an LTE radio access technology (RAT) to acquire services in a CSFB mode, methods implemented in a mobile communication device (e.g., a simultaneous GSM/LTE+GSM communication device) determine whether an available network is capable of supporting circuit-switch fallback (CSFB) operations for the LTE RAT and configure the LTE RAT to acquire services in either a CSFB mode or an SGLTE mode based on the network's capabilities. In response to determining that the mobile communication device has entered a new tracking area in the LTE RAT's network, a mobile communication device processor may determine whether a network available in the new tracking area supports CSFB operations and may configure the LTE RAT to operate in either a CSFB mode or an SGLTE mode based on that determination, thereby potentially improving the LTE RAT's overall performance and quality of services.

Abstract: Various embodiments implemented on a mobile communication device leverage the availability of multiple RATs to receive service from a combination of RATs that avoids the potential for inter-RAT coexistence interference. A mobile communication device processor may determine whether there is a likelihood of inter-RAT coexistence interference between a first RAT and a second RAT. In response to determining that there is a likelihood of interference occurring between the first RAT and the second RAT, the device processor may attempt to receive service with the first RAT and a third RAT that will not interfere with the first RAT. The device processor may monitor conditions to recognize when the likelihood of interference no longer exists between the first RAT and the second RAT, and reestablish service with the second RAT when that happens. Thus, the device processor may ensure that service is only acquired with non-interfering RATs.

Abstract: Methods and devices are disclosed for enabling efficient network registration using a shared radio resource for at least a first and second SIM of a multi-SIM wireless communication device. An overall priority-based ranking may be calculated for each SIM of the multi-SIM device, which may be used to determine an preferred order for the SIMs to register for services in their respective networks. Calculating the overall priority-based ranking for each SIM may include determining values for a service capability priority factor, an attachment time factor, and a sleep cycle duration factor.

Abstract: Methods, systems and devices for prioritizing communication technologies to allocate resources in a mobile device. The mobile device may employ a dual subscription, dual active (DSDA) configuration in which two subscriptions may be associated with concurrently active communications, such as voice or data calls. The mobile device may identify current states that indicate the type of communications associated with the subscriptions. In an embodiment, an applications processor within the mobile device may perform the state identifications. The mobile device may determine priorities of the concurrently active subscriptions based on the identified states. In an embodiment, the priorities may be determined by a modem processor within the mobile device. When the priorities are determined to be the same, the mobile device may perform a tiebreaker algorithm to further identify priorities. Based on the determined priorities, the mobile device may allocate resources to favor the subscription with the higher priority.

Abstract: Methods and devices are disclosed for enabling efficient service acquisition on multiple SIMs of a multi-SIM device. After at least one SIM has maintained or reacquired a network connection, the wireless device may identify that network, access a joint acquisition database, and determine whether there is a correlated network entry showing a network from which service may be received on SIM-2. In this manner, the wireless device may automatically prioritize a network for a recovery scan on SIM-2, thereby overriding conventional priority given to the network that was most-recently-used by SIM-2.

Abstract: Methods, devices, and systems embodiments enable recovering from an out-of-service state in a wireless device. A processor may perform scans of first and second acquisition databases to acquire a first renewed service connection for a first subscriber identification module (SIM). The scans include first and second searches for first channels identified in first and second technology lists, respectively, from the first and second acquisition database, respectively, until either a renewed service connection is acquired or each of the first and second technology lists are exhausted. The first and second technology lists identify channels from a most recently used radio access technology of the respective acquisition databases. The processor may perform a full frequency scan to acquire a first renewed service connection for the first SIM in response to determining that each of the first and second technology lists were exhausted.

Abstract: Methods, devices, and systems embodiments enable efficient service acquisition on multiple subscriber identification modules (SIMs) of a multi-SIM wireless device. A processor may determine whether the first SIM has acquired a first service with a first wireless network while the second SIM is operating in a second SIM deep sleep period. The processor may also trigger the second SIM to operate in an awake state, prior to expiration of the second SIM deep sleep period, to acquire a second service with a second wireless network in response to determining that the first SIM has acquired the first service with the first wireless network.

In further aspects, the disclosure provides for various optimizations to expedite a PLMN scan, which may be implemented either with the partial PLMN scan, or in a full PLMN scan, to further expedite the provision of PLMN scan results to the user.

Abstract: Systems and methods use the capabilities of multiple SIMs to prevent calls from being dropped on a multi-SIM wireless device. In the various embodiments, network conditions may be monitored for signal quality during an active call. When signal quality on the network deteriorates, the multi-SIM wireless device may switch the active call to a network associated with a different SIM that provides better service. To enable the switch, the multi-SIM wireless device may setup a conference call with the called party and the different SIM. In the various embodiments, the multi-SIM wireless devices may be a dual-SIM dual active (DSDA) wireless device.

Abstract: Aspects of the present disclosure relate to wireless communications and techniques for determining a power save duration for an out of service subscription based, at least in part, on a detected mobility status change of a mobile device. Aspects generally include a mobile device, that shares a single radio resource for establishing connections with a first and second subscription, using a detected mobility status change to determine a power saving duration for an out of service subscription.

Abstract: A mobile communication device includes a domain selection feature that allows a user to select a domain preference such as a circuit switched (CS) voice domain preference, a packet switched (PS) data domain preference, or a (CS+PS) domain preference. The mobile device receives Public Land Mobile Network (PLMN) ID and domain availability information from one or more PLMNs. A PLMN priority list is generated on the basis of the received PLMN information and the user domain preference selection. PLMNs having the user selected service available are assigned a higher priority than those that don't currently have the service, whereby an original PLMN list may be updated. Thereby, the mobile device is more likely to obtain the desired service without resorting to a time consuming manual selection process.
