摘要： 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.

摘要： A method for performing data service switch for a mobile communication device having a first subscription configured as a dedicated data subscription (DDS) and a second subscription includes: receiving a multimedia messaging service (MMS) message notification on the second subscription; calculating an approximate transfer time for receiving the MMS message; determining the that the approximate transfer time is less than a specified time; in response to determining that the approximate transfer time is less than the specified time, performing at the mobile communication device a local packet switched (PS) service detach procedure for the first subscription; performing a circuit switched (CS) service attach procedure for the first subscription; and performing a PS service attach procedure for the second subscription.

摘要： 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. Memory accesses requests to the single contiguous combined memory may be made using a variety of communications protocols and translated such that at least one of the multiple memory access requests for the individual memories is made using USB communications protocols.
摘要翻译：各种实施例包括用于在多时隙通信设备上管理多个存储器作为单个连续组合存储器的方法和装置。存储器可以包括各种类型的通用串行总线（USB）和/或通用集成电路卡（UICC）存储器。每个存储器的部分的物理地址的范围可以与单个连续组合存储器的虚拟地址的范围相关联。物理和虚拟地址的关联可以存储在多时隙通信设备上。可以使用虚拟地址对单个连续的组合存储器进行单个存储器访问请求，使用物理地址转换成对于各个存储器的多个存储器访问请求。可以使用各种通信协议来对存储器访问对单个连续组合存储器的请求进行转换，使得使用USB通信协议来进行对各个存储器的多个存储器访问请求中的至少一个。
