Techniques are disclosed for transmitting an announcement to one or more devices. In one example, a first device receives a first message that includes an announcement, the announcement associated with a voice that spoke the announcement. The first device may determine the announcement from the first message, and then identify one or more devices for receiving the announcement. The one or more devices may have a particular device type of a plurality of different device types comprising at least a mobile device. The first device may then transmit a second message to the one or more devices for presentation of the announcement by the one or more devices.

Disclosed are various embodiments for facilitating social interaction during a media item transmission. A group of participants may be formed based on a variety of factors. A media item is rendered on a first portion of a media player user interface. On a second portion of the media player user interface group members may communicate with each other concurrent with the streaming media item. The entire experience may be stored and replayed at another time.

A device for providing a location-based automatic participation chat room, the device, when a request to open a chat room is received along with service location information from at least one host terminal, creates at least one chat room, and sets a chat room identifier and a recognition code corresponding to each of the at least one chat room, and when at least one guest terminal accesses a location corresponding to the service location information using a pre-set participation means or the recognition code included in the participation means is received, makes the guest terminal participate in the chat room corresponding to the recognition code.

Systems and methods for communicating alerts to vehicles based on vehicle movement are disclosed. According to an aspect, a method includes determining movement of one or both of first and second vehicles. The method also includes analyzing the determined movement based on a predetermined criteria. Further, the method includes receiving user input for vehicular communication of an alert. The method also includes communicating an alert to the second vehicle based on the analysis in response to receiving the user input.

Multicast expert system information dissemination systems and methods making use of artificial intelligence are provided. The systems and methods include a wireless device for receiving RF multicast information messages from a content provider wherein said information is descriptive of objects potentially of interest to users of the device. Received multicast messages may include information parameters about objects of potentially interest to the user. The wireless device also includes a knowledge base prestored in the wireless device descriptive of the user's level of interest in various objects. Artificial intelligence expert system control is used to evaluate a combination of the user's level of interest in the object information and distance from the user to the location where the object may be obtained. The artificial intelligence expert system derives a user advisory action index. In one embodiment the artificial intelligence may be implemented using fuzzy logic inference engine apparatus.

A method for improving service reliability includes deciding, by a session function entity in a network, to initiate establishment of at least two transmission paths between a terminal and the user plane function entity, and instructing the terminal or the user plane function entity to transmit same data on the at least two paths. The user plane function allocates, based on a notification of the session function entity, user plane resources to the at least two transmission paths, and transmits the same data with the terminal on the at least two transmission paths. A core network initiates the establishment of the at least two transmission paths to the terminal. Two access devices may independently establish the at least two transmission paths.

A system for proximity-based analysis of multiple entities includes a first communication device associated with a first entity and an additional communication device associated with an additional entity, wherein the first communication device and the additional communication device are communicatively couplable. The system includes one or more processors communicatively coupled to at least one of the first communication device or the at least an additional communication device. The one or more processors are configured to: identify a spatial relationship between the first entity and the additional entity based on one or more signals from the first communication device or the additional communication device, identify an operation unit defined by an association between the first entity and the additional entity based on the spatial relationship between the first entity and the at least the additional entity, and report one or more characteristics of the operation unit.

In one embodiment, a method comprises: identifying, by a low power and lossy network (LLN) device in a low power and lossy network, a minimum distance value and a distance limit value for limiting multicast propagation, initiated at the LLN device, of a multicast data message in the LLN; and multicast transmitting, by the LLN device, the multicast data message with a current distance field specifying the minimum distance value and a distance limit field specifying the distance limit value, the multicast transmitting causing a receiving LLN device having a corresponding rank in the LLN to respond to the multicast data message by: (1) determining an updated distance based on adding to the current distance field a rank difference between the receiving LLN device and the LLN device, and (2) selectively retransmitting the multicast data message if the updated distance is less than the distance limit value.

A vehicle network transmission method and a vehicle network transmission system are provided. The vehicle network transmission method comprises the following steps. A first transmission device transmits a data signal to a second transmission device. It is determined whether the second transmission device is located in a target area. If the second transmission device is located in the target area, then a geographic location of the first transmission device is retrieved and a transmission region of the first transmission device is calculated. It is determined whether all of the third transmission devices adjacent to the second transmission device in the target area are located in the transmission region. If all of the third transmission devices adjacent to the second transmission device in the target area are located in the transmission region, then the second transmission device does not continue forwarding the data signal.

A method for broadcasting messages in a cellular mobile communications system with broadcast functionality includes the steps of: selecting a geographic area over which the message broadcasting must be carried out; obtaining information adapted to identify the languages used in mobile terminals referring to the cellular mobile communications system within the geographic area; composing the messages in the set of the identified languages, thus obtaining one or more multilanguage messages; broadcasting the one or more multilanguage messages to said mobile terminals.
