摘要： A device executing a low-latency application that uses a Wi-Fi link may switch from the Wi-Fi link to using a second link to a multi-subscriber (MSIM) PHS device. The device may access, via the second link, any one of multiple cellular links, each cellular link corresponding to a different respective cellular subscription of multiple subscriptions used by the PHS device. The application executing on the device may thus use a preferred cellular link from among the multiple cellular links. The preferred cellular link may be determined based on parameters corresponding to the plurality of cellular links for each respective cellular subscription. The parameters may be obtained from a location database. The preferred cellular link (which may presently correspond to a primary subscription) on the PHS device may be switched to be a different cellular link (which may correspond to a non-primary subscription) during execution of the application on the device.

摘要： Wireless devices, networks and methods may operate to have a wireless device cause a base station to trigger voice call continuity handovers responsive to the quality of the cellular radio link in addition to the base station triggering such handovers based on location or mobility. Furthermore, wireless communication devices may also perform monitoring of multiple buffers operating within the wireless communication device and associated with different respective communication layers, in addition to monitoring the quality of the cellular radio link, to perform intelligent dropping/discarding and/or scheduling of packets at the wireless communications device. Any one or more of these features may improve the ability of the wireless communications device to achieve stated Voice over Long Term Evolution (VoLTE) performance benchmarks in the context of the realities of current VoLTE networks.

摘要： Techniques are disclosed relating to a mobile device that initiates handovers from short-range networks to long-range networks. In various embodiments, a mobile device includes one or more radios that communicate using a plurality of radio access technologies (RATs) including a cellular RAT and a short-range RAT. In such an embodiment, the mobile device stores an indication that the cellular RAT is a preferred RAT for a communication session. The mobile may establish the communication session using the preferred RAT, and in response to determining that a quality of the preferred RAT fails to satisfy a set of quality criteria, may request that the communication session use the short-range RAT. In some embodiments, the mobile device analyzes average packet error rate for the communication session and in response to the average packet error rate satisfying a threshold, requests that the communication session use the cellular RAT.

摘要： This disclosure relates to techniques for a wireless device to detect network bandwidth throttling and dynamically select a buffer threshold. The wireless device may establish a wireless link. Data for a downlink stream may be requested when an amount of buffered data for the stream is below a lower buffer threshold, received via the wireless link, and buffered. Data requests for the stream may be stopped when the amount of buffered data for the stream is above an upper buffer threshold. The upper buffer threshold may be selected based on characteristics of the wireless link and the stream. Throughput of the wireless link may also be monitored during multiple time windows, and the wireless device may determine whether the wireless link caps bandwidth below a bandwidth threshold based on the throughput monitoring.

摘要： Apparatus and methods to support authentication failure handling by network elements and by a wireless communication device when attempting access to services through non-cellular wireless networks by the wireless communication device are disclosed. Error messages received from evolved packet core (EPC) network elements, such as an authentication, authorization, and accounting (AAA) server, are mapped to failure messages provided to wireless communication devices by internetworking equipment, such as an evolved packet data gateway (ePDG). The wireless communication device determines a failures cause based on the failure messages and disallows retry attempts until select criteria are satisfied.

According to some embodiments, the base station may monitor upcoming traffic with the wireless device. Based at least in part on the upcoming traffic for the wireless device, the base station may provide a command indicating to the wireless device to enter C-DRX. The command may further indicate to the wireless device a number of C-DRX cycles through which to remain in a low power state.

摘要： Embodiments relate to apparatus, systems, and methods for reception of calls on a mobile device that includes Wi-Fi and cellular radios. The mobile device may be configured to establish communication on a Wi-Fi network with a cellular carrier. The mobile device may further be configured to register a first IP address with an IMS server for the Wi-Fi network communication and register a second IP address with the IMS server for the cellular network communication (or register different ports of a single IP address with Wi-Fi and cellular). Upon occurrence of a mobile terminating call from the cellular carrier, the mobile device may receive an incoming call notification on one or both of the Wi-Fi network using the first IP address and the cellular network using the second IP address.
