A printing system provides a printer for printing indicia on a container within a vending machine. The printing system may print indicia based on information relevant to a purchase transaction. The vending machine may transmit to a remote server data relating to a purchase transaction entered into the vending machine, the remote server retrieving data relevant to the purchase transaction and/or to the purchaser and transmitting to the vending machine the data relevant to the purchase transaction, such that the printing apparatus prints indicia on the container based on the received data relevant to the purchase transaction.

Non-text content may be exchanged in real time text (RTT) messages over a telecommunications network as part of an enhanced RTT (eRTT) service. A first UE can receive, from a second UE over a telecommunications network, capability information indicating whether the second UE is capable of exchanging text content and/or non-text content via RTT messages. Using this capability information, the first UE may determine whether to enable eRTT functionality on the first UE by determining whether to display a user interface element(s) in a selectable state on the display next to a RTT conversation window. The selectable user interface element(s), upon selection, allows a user of the first UE to create new non-text content, or select particular non-text content from available non-text content, for inclusion in a RTT message. The first UE may thereafter send non-text content in the RTT message to the second UE.

Systems, methods, and computer program products are provided for improving establishment and broadcasting of audio communication among mobile computing devices and for improving switching from listening mode to conversation mode on a mobile application. For example, a method comprises: receiving a selection of a conversation mode option from the user interface of the mobile application on a first mobile device of a first user displaying the conversation mode option simultaneously with both a first visual representation of a second user involved in the first audio conversation, and the second visual representation of a third user involved in the first audio conversation; and in response to receiving selection of the conversation mode option, modifying a first image of the conversation mode option, and placing the first user in the first audio conversation with the second user and the third user, or in a second audio conversation with a fourth user.

A high-availability (HA) framework for services deployed in provider network environments. Services may be deployed as machine images or containers to a provider network. The HA framework provides a “wrapper” around the deployed services that provides feedback loops and flow control for inbound and outbound communications to other services on the provider network or to other external entities. The HA framework intercepts inbound and outbound traffic to the service, and may automatically determine, configure, and adjust networking management aspects such as timeouts, flow control, etc. for the service. The HA framework may also intercept outbound traffic to monitor outbound connections to other services to determine if the services satisfy HA requirements of the service.

A wireless communication network is configured to wirelessly deliver a media content service to wireless User Equipment (UEs). The wireless communication network comprises network circuitry. The network circuitry executes wireless network functions and media content functions. The media content functions distribute network addresses to the wireless UEs which use the network addresses to transfer media-content for the media-content service. The wireless network functions monitor performance of the media content functions. The wireless network functions prioritize the media content functions based on their performance. The wireless network functions transfer the prioritized list of the media content functions to the wireless UEs. The wireless UEs communicate with the media content functions on a priority basis responsive to the prioritized list.

Disclosed are various embodiments for scalable notification deliveries in computing environments. A subscription request is transmitted along with a user identifier, a service identifier, a subscription identifier, and a channel identifier. Notifications are communicated through a notification multiplexing channel between two nodes of a computing environment. The notification multiplexing channel includes notifications multiplexed by subscription identifiers. The notification multiplexing channel corresponds to the channel identifier. A notification corresponding to the subscription identifier is identified and provided to a client computing device associated with the user identifier.

Disclosed is a method, system, and non-transitory computer-readable record medium for providing a plurality of group calls in a single chatroom. A group call providing method including receiving, by the at least one processor, information about a plurality of group call channels generated in response to a first request from at least one member included in a chatroom, from a server, providing, by the at least one processor, a group call channel list about the plurality of group call channels through the chatroom based on the information about the plurality of group call channels, and starting, by the at least one processor, a group call through a specific group call channel, from among the plurality of group call channels, in response to receiving a second request for joining the specific group call channel through the group call channel list may be provided.

Disclosed is a method, system, and non-transitory computer-readable record medium for creating a chatroom according to a condition. The chatroom creation method may include providing an instant messaging service; registering a chatroom creation condition related to a specific account of the instant messaging service; retrieving at least one account of accounts of the instant messaging service that meets the chatroom creation condition; and automatically creating a chatroom of the specific account joined by the retrieved accounts.
