Abstract: A messaging system, in one embodiment, can establish messaging accounts for a plurality of organizations (e.g., businesses) to allow customers or users of the organizations to conduct two-way messaging sessions between a customer and an organization. The messaging system can use a registration portal to allow an organization to set up a business/organization messaging account by providing account information. The account information can then be used to update one or more searchable databases that allow a customer to have multiple entry points into a messaging session with each of the registered businesses in the messaging system. For example, a search through a web browser or a map application can provide search results that contain or otherwise provide access to a selectable messaging option that is presented on a customer's device.

Abstract: Power optimization modes for communication between a device and a server is disclosed. The device can dynamically change between communication modes based on an application or quality of service, battery life, an amount of noise associated with the communications link, a frequency of messages, and a type of message received in a given time period. In some examples, the device can determine if the number of pull messages is greater than the number of push messages. The device can select a push mode where a pull message can accompany a push message. In some examples, the device can determine that the number of push messages is greater than the number of pull messages, and the device can select a low-power associated sleep mode.

Abstract: Some embodiments relate to a device that transmits/receives encrypted communications with another device. A first device, such as a smart phone or smart watch, may generate a message associated with a certain data class, which may determine the security procedure used in the communication of the message. The first device may establish an encryption session for the purpose of communicating the message to a second device. Prior to sending the message, the first device may wait until encryption credentials are accessible according to certain conditions, which may be determined at least in part by the data class of the message. Similarly, after receiving the message, the second device may not be able to decrypt the message until encryption credentials are accessible according to certain conditions, which may be determined at least in part by the message data class.

Abstract: A user equipment (UE) device and associated methods for entering a suspended baseband state in response to a signal strength indicator falling below a threshold. A UE engages in an active connection with a remote server, which may be a transmission control protocol (TCP) push connection. A baseband layer of the UE determines that the signal strength indicator has fallen below a threshold, and transmits a notification to an application layer of the UE to suspend the connection. The baseband layer may later determine that the signal strength has risen above a second threshold, whereby the UE may resume the suspended connection. The UE may maintain state information associated with the connection during the suspended state, such that the UE may resume the suspended connection without reestablishing a new connection with the remote server.

Abstract: A notification server may be configured to receive a message from a device, determine a device location from the message, determine a location identifier corresponding to the determined device location, and send the location identifier to the device. The device may be configured to generate a configuration identifier based on the location identifier and send a configuration data request including the configuration identifier to a cache server. The cache server may be configured to receive the configuration data request from the device, select a device configuration corresponding to the configuration identifier, where the device configuration is specific to the device location, and send the selected device configuration to the device. The device may be further configured to configure the device according to the selected device configuration.

Abstract: A system and method are described for establishing two-way push communication between an intermediate or companion device and a mobile device. Mobile devices register to listen for push notifications delivered through a push notification service from a specified set of providers. The presence of the mobile devices is delivered to the push notification service that maps the mobile devices to connections made between their respective companion devices and the push notification service. If the push notification service determines that a mobile device is “online,” in response to receiving a push notification for the mobile device, a current network connection over which a companion device is listening for push notifications is identified and the push notification is forwarded to the companion device. The companion device then can deliver the push notification to the mobile device.
