摘要

In some embodiments, a UE is configured to, in response to detecting an absence of received packets associated with a voice call over a first time interval of a pre-determined length, initiate transmission of a first control packet to a base station. In some embodiments, the UE is further configured, based on a response to the first control packet, not to drop the packet-switched voice call at least until expiration of a second time interval of a pre-determined length after transmission of the first control packet. In some embodiments, the absence of received packets is an absence of both voice and silence packets. In some embodiments, based on absence of a response to the first control packet, the UE is configured to drop the packet-switched call.

說明書

FIG. 3 illustrates an exemplary block diagram of a UE 106, according to some embodiments. As shown, the UE 106 may include a system on chip (SOC) 300, which may include processing elements for various purposes. For example, as shown, the SOC 300 may include processor(s) 302 which may execute program instructions for the UE 106 and display circuitry 304 which may perform graphics processing and provide display signals to the display 360. The processor(s) 302 may also be coupled to memory management unit (MMU) 340, which may be configured to receive addresses from the processor(s) 302 and translate those addresses to locations in memory (e.g., memory 306, read only memory (ROM) 350, NAND flash memory 310) and/or to other circuits or devices, such as the display circuitry 304, wireless communication circuitry 330, connector I/F 320, and/or display 360. The MMU 340 may be configured to perform memory protection and page table translation or set up. In some embodiments, the MMU 340 may be included as a portion of the processor(s) 302.

As shown, the SOC 300 may be coupled to various other circuits of the UE 106. For example, the UE 106 may include various types of memory (e.g., including NAND flash 310), a connector interface 320 (e.g., for coupling to a computer system, dock, charging station, etc.), the display 360, and wireless communication circuitry 330 (e.g., for LTE, Wi-Fi, GPS, etc.).
