摘要： Approaches enable a device, such as a cellular-enabled device, to receive cellular system information from another device in response to a request by the cellular-enabled device, and then to select a cellular network connection to which the cellular-enabled device can connect based on the cellular system information. The cellular-enabled device may determine the availability of the cellular system information in a number of ways, such as by detecting a Bluetooth broadcast from another device and initiating a paired connection between the two devices. Once the paired connection is established, the cellular-enabled device may make a service discovery request to learn that the other device is capable of broadcasting the cellular system information over the connection between the devices. The cellular system information may be used by the cellular-enabled device to select one cellular network connection, from a set of available cellular network connections compatible with the cellular-enabled device, to connect to.

摘要： In an LTE (Long Term Evolution) system, a radio access network (RAN) is configured to detect and report congestion radio congestion to a core network. RAN congestion may be indicated by lost, discarded, or retransmitted data packets. In response to being notified of congestion at the RAN, the core network of the system modifies properties of data bearers and data flows between the core network and the RAN, such as by modifying QoS commitments where possible and remapping data flows.

摘要： Systems and methods for a device-to-device communications mode are described. When two user equipment are within proximity of each other and other requirements are met, the user equipment are configured by their associated nodes to enter a device-to-device communication mode. In that mode, the user equipment receives messages from the other user equipment without the messages traversing the core network between their associated nodes.

摘要： 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.

摘要： Systems and methods for a multi-connectivity DRX mode are described. When a device is concurrently connected to more than one node of a wireless network, a first node may determine a DRX configuration for both a first communication channel between the device and the first node and a second communication channel between the device and the second node based on an existing DRX cycle of the second communication channel. The DRX configuration may be sent to the device, so that the device may use the DRX configuration when concurrently connected to the first node and the second node of the wireless communication network.

摘要： Receiving short message service (SMS) messages and providing a response report based at least in part on the received SMS message is disclosed. A user equipment (UE) may receive an SMS message via a communications link between the UE and mobile a mobile communications network. The UE may be configured to determine if the SMS message was received with or without error. Based at least in part on this determination, the UE may generate the response report to provide to the mobile communications network. The UE may further identify that the communications link between itself and the mobile communications network may be severed. As a result, the UE may reestablish the communications link with the mobile communications network and then transmit the response report.
