[27] Mode for carrying out the invention

The embodiments of the present invention will be further described in detail below with reference to the accompanying drawings and embodiments.

[29] As shown in Figure 1, is MGC

Schematic diagram of networking with MG. The Media Gateway Control Protocol is the main protocol for communication between the MG and the MGC. Currently, H.248/MeGaC ₀ (Gateway Control Protocol) and MGCP (Media Gateway Control Association) are widely used. Two protocols, and H.248/MeGaCo is based on the development of MGCP. Taking H.248 as an example, various resources on the MG are abstractly represented as terminals (Termination). The terminal is further divided into a physical terminal and an Ephemeral terminal. The former represents some semi-permanent physical entities, such as TDM gaps, and the latter represents some public resources released after the application, such as RTP. Flow and so on. The MG as a whole is represented by a special terminal called a root terminal. The association between terminals is abstracted as a context. The context can contain multiple terminals, so the topology (Topol ogy) is used to describe the interrelationship between terminals. A terminal that has not been associated with another terminal is included by a special context called a null context.

[30] Based on the abstract connection model described above, the interaction between the business and the bearer is actually reflected in the operation of Terminati on and Context. This operation is through a command (Command) request between the MGC and the MG.

(Request) and Response (Reply) to complete. Command types include Add, Modif y, Subtract, Move, AuditValue, Audit Capabilities, Notify, and ServiceChange. Command parameters, also known as descriptors (Descriptor), are classified as properties, signals, events, statistics, and so on. In order to facilitate the logical aggregation of parameters into packages based on business relevance.

[31] The MGC's control of the MG can be directed to the flow on the terminal or terminal. The terminal state (TerminationSta te) descriptor is used to include non-stream specific characteristics on the terminal, such as service state (ServiceState), event buffer control (EventBufferControl), and the like. A media-specific feature is included through a Media (Descriptor) descriptor, which can contain several Stream descriptors. Each stream descriptor is for a single stream and contains local control (LocalControl), local (Local) and remote (Remote) descriptors. The local control descriptor is used to include flow-related control information such as Mode, Reserve Group, and ReservedValue. The local and remote descriptors are respectively used to include features of the stream received by the local end and the remote end, such as an address and a port, a codec algorithm, and the like, and a description form of a Session Description Protocol (SDP) is specifically used.

[32] As shown in FIG. 2, the process of implementing media broadcast information reporting in the first embodiment of the present invention includes:

[33] Step 201: After the MG performs media playback, the media is completed according to the completion event.
