    Abstract: An apparatus, method and system for receiving an input indicating a mode into which to set a user equipment (UE) and at least one further UE associated with the UE, determining whether a connection circuit switched (CS) connectivity or packet switched (PS) connectivity and when the connection is the CS connectivity, generating a short messaging service (SMS) message that indicates the mode corresponding to the input. Also, receiving connectivity information for a plurality of UEs from a cloud network component, the UEs being associated with one another, the connectivity being CS connectivity or PS connectivity, receiving a response indication corresponding to a response performed on an incoming call by a first one of the UEs, the first UE having a PS connectivity, matching the response indication to a corresponding cause code and transmitting the corresponding cause code to a second one of the UEs having a CS connectivity.

    Abstract: This disclosure relates to wireless connection management for an accessory device. A companion device and the accessory device may establish a wireless link. The companion device may associate with a Wi-Fi access point. The companion device may determine whether the Wi-Fi access point supports access by the accessory device to a wide area network. The companion device may determine whether to provide association information for the Wi-Fi access point to the accessory device based at least in part on whether the Wi-Fi access point supports access by the accessory device to the wide area network. The companion device may monitor whether the Wi-Fi access point continues to support access by the accessory device to the wide area network, and may indicate to the accessory device to disassociate with the Wi-Fi access point if the Wi-Fi access point no longer supports access by the accessory device to the wide area network.

    Abstract: 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.

    Abstract translation: 在一些实施例中，UE被配置为响应于在预定长度的第一时间间隔上检测到与语音呼叫相关联的接收到的分组的缺失，启动向基站发送第一控制分组。 在一些实施例中，UE进一步配置为基于对第一控制分组的响应，至少在传输第一控制之后至少等待预定长度的第二时间间隔到期之前丢弃分组交换语音呼叫 包。 在一些实施例中，没有接收到的分组是没有语音和静音分组。 在一些实施例中，基于没有对第一控制分组的响应，UE被配置为丢弃分组交换呼叫。

    Abstract: Devices and methods for handling phone calls. One device is a user equipment (UE) configured to establish a connection with a first evolved Node B (eNB). A method includes transmitting an invite signal to a further UE for a Voice over LTE (VoLTE) call, receiving an accept signal from the further UE, receiving a fail signal from the first eNB that a dedicated bearer is unavailable, generating a trigger signal in response to receiving the fail signal and transmitting the trigger signal to the first eNB. Another device is a base station (e.g., eNB) that receives a VoLTE call request from a UE, determines whether the eNB has sufficient resources to provide a dedicated bearer. When it is determined the eNB has insufficient resources, the eNB determines whether a further eNB has sufficient resources to provide the dedicated bearer, and determines whether the UE can connect to the further eNB.
