Provided is an apparatus and method for inserting an advertisement in a broadcasting system based on adaptive streaming. To this end, content related information for advertisement content is generated by an advertisement providing server and a content transmitting server. A client is informed of an update required time of the content related information to receive new content related information from the content transmitting server. Therefore, the advertisement content can be reproduced in a set period.

A method of authenticating a video streaming transmission comprising generating a secure token at an application server, providing the secure token to a user device, receiving the secure token at a media server with a publish request from the user device, transmitting the secure token to the application server for authentication, and authenticating the secure token. The publish request from the user device is enabled if the secure token is authenticated by the application server. The connection between the media server and the user device is terminated if the secure token fails to authenticate.

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.

A method for associating a network service (NS) with a virtualized network function (VNF), an apparatus, and a system such that a network manager (NM) can determine a relationship between an NS and a VNF, and maintain the NS. The method includes sending, by an NM, an NS instantiation request message to a network function virtualization orchestrator (NFVO), receiving an NS instantiation completion message from the NFVO, and determining a mapping relationship between a first NS and N VNFs according to information about the first NS and information about the N VNFs. The NS instantiation request message carries the information about the first NS, the NS instantiation completion message carries the information about the first NS and the information about the N VNFs, information about each VNF in the information about the N VNFs represents the VNF in the N VNFs forming the first NS, and N≧1.

Concepts and technologies are disclosed herein for message flow management for virtual networks. A processor can identify a target virtual network function instance that is to be taken offline. The processor can change a status associated with the target virtual network function instance to indicate it being taken offline. The processor can start a graceful shutdown timer to trigger shutdown of the target virtual network function instance. The processor can identify external interfaces and a peer network function that identifies the target virtual network function instance as a next hop. The processor can obtain, for the target virtual network function instance and the peer network function instance, a snapshot that identifies configuration data for the target virtual network function instance and the peer network function instance and can generate a command to trigger a shutdown of the target virtual network function instance.

A storage network element discovery method and an apparatus, where the method includes broadcasting or multicasting, by a control network element, a heartbeat message to at least one storage network element, where the heartbeat message includes address information of the control network element, receiving, by the control network element, a response message returned by at least one storage network element according to the heartbeat message, and determining an accessible storage network element according to the response message, where the response message includes network parameter information of the corresponding storage network element. Therefore, in a storage array, by broadcasting or multicasting a heartbeat message and according to a reply from a storage network element, a control network element may determine a storage network element that can be accessed by the control network element.

A system adapted to provide multimedia content to a set of users is described. The system includes: a storage adapted to store at least one multimedia content item, each multimedia content item associated with a publisher-user; a set of destination devices, each destination device associated with a subscriber-user, each subscriber-user being associated with the publisher-user; and a server adapted to provide each multimedia content item to the set of destination devices. A method adapted to allow a creator to generate and distribute at least one multimedia content item to a set of subscribers is also described. In addition, a server application adapted to provide at least one multimedia content item to a set of destination devices is described. Furthermore, a server application adapted to allow a creator to compose a multimedia content item is described.

A device may receive, from a user device, a request to establish a voice call. The device may determine that one of a plurality of endpoints is to be involved in the voice call with the user device. The device may transmit send-only invites to the plurality of endpoints. The device may receive, from a first endpoint of the plurality of endpoints, a receive-only response. The device may transmit a send-receive invite to the first endpoint, wherein the send-receive invite identifies a selected communication protocol as a communication protocol for the voice call. The device may transmit a send-receive acceptance to the user device. The send-receive acceptance may identify the communication protocol for the voice call, and upon the user device receiving the send-receive acceptance, the voice call can be established between the user device and the first endpoint.

Provided are a policy control method and device for one or more terminal peripherals. The method includes: an M2M gateway executing one or more operations for one or more terminal peripherals according to a transaction trigger condition in policy definition, wherein the one or more operations for the one or more terminal peripherals are one or more operations corresponding to the transaction trigger condition in the policy definition. The solution solves the technical problem in the related art that it is impossible to implement control for one or more terminal peripherals through the M2M gateway according to the policy definition, which implements policy control of one or more terminal peripherals through the M2M gateway and improves the intelligent degree of an M2M system.
