Abstract: Various embodiments include methods and apparatuses for managing multiple memories on a multi-slot communication device as a single contiguous combined memory. The memories may include various types of universal serial bus (USB) and/or universal integrated circuit card (UICC) memories. Ranges of physical addresses of portions of each memory may be associated with a range of virtual addresses of the single contiguous combined memory. Associations of physical and virtual addresses may be stored on the multi-slot communication device. A single memory access request to the single contiguous combined memory may be made using the virtual addresses, translated into multiple memory access requests for the individual memories using the physical addresses.

Abstract: Methods and devices are disclosed for enabling improved service acquisition on at least one SIM of a wireless communication device. After a first SIM has lost service, the wireless communication device may identify, in a first radio access technology (RAT) priority list configured to support the first SIM, a highest ranked radio access technology. The wireless communication device may search a local wireless environment for networks associated with the identified radio access technology, and determine whether any network associated with the identified radio access technology is available, Upon determining that the no network associated with the identified radio access technology is available, the wireless communication device may update the RAT priority list associated with the first SIM.

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: Various embodiments enable recovering from an out-of-service state in a wireless device. A processor may perform scans of a first acquisition database to acquire a first renewed service connection for a first subscriber identification module (SIM). The scans include first and second searches for first and second channels identified in first and second technology lists, respectively, from the first 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 first and second radio access technologies. A currently used channel of a second SIM acquired service is first on the first technology list. 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: 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, 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.

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.
