Abstract: Sending short message service (SMS) messages and receiving a response report based at least in part on the sent SMS message, even if a communicative connection with the mobile communications network had been severed, so that duplication of the SMS message is avoided is disclosed. In this case, a communicative connection may be re-established and used to receive an acknowledgment from the mobile communications network and subsequently send another acknowledgement to the mobile communications network. The UE may also be configured to send an information element to the one or more elements of the mobile communications network to indicate that a communicative connection with the network is to remain established so that acknowledgements may be reconciled between the UE and the network. Additionally, the mobile communications network may be configured to transmit the SMS message only after receiving the acknowledgement from the UE, to avoid sending duplicate SMS messages.

Abstract: A system and method for network channel selection is provided. A device includes WIFI, ZIGBEE, and BLUETOOTH communication controllers. The device's processor is configured to determine, using the communication controllers, a WIFI channel designated for communications and a first set of ZIGBEE channels designated for communications. The processor is configured to determine that a number of available BLUETOOTH channels that do not overlap the WIFI channel or any in-use ZIGBEE channels is less than a threshold number of BLUETOOTH channels required for communication using a BLUETOOTH protocol. The processor then determines the WIFI channel has a minimum duty cycle from among duty cycles of the WIFI channel and each ZIGBEE channel, determines a first BLUETOOTH channel that at least partially overlaps the WIFI channel, and causes the BLUETOOTH communication controller to transmit data using the first BLUETOOTH channel.

Abstract: Described are techniques for enabling a computing device, such as a slave device using a Bluetooth Advanced Audio Distribution Protocol (A2DP), to determine times when a master device is likely to be idle, during which communications using an alternate protocol, such as Wi-Fi may be exchanged. The length of a delay period may be determined based in part on counts of successive communications received from a master device. The length of a transmission period for use of the alternate protocol may be determined based in part on lengths of time between sets of communications received from a master device. If no communication is received from the master device for a length of time greater than or equal to the delay period, data may be communicated using the alternate protocol for a length of time less than or equal to the transmission period.

Abstract translation: 发送短消息服务（SMS）消息并且至少部分地基于所发送的SMS消息来接收响应报告，即使与移动通信网络的通信连接已被切断，从而公开了避免SMS消息的复制。 在这种情况下，可以重新建立通信连接并用于从移动通信网络接收确认，并且随后向移动通信网络发送另一个确认。 UE还可以被配置为向移动通信网络的一个或多个元件发送信息元素，以指示与网络的通信连接将保持建立，使得可以在UE和网络之间协调确认。 此外，移动通信网络可以被配置为仅在从UE接收到确认之后才发送SMS消息，以避免发送重复的SMS消息。
