摘要： An apparatus and a method for megaco protocol conversion is provided. The apparatus includes: a plurality of first protocol execution units for receiving a plurality of protocol packets, executing operations according to the received protocols, analyzing the received protocols, and generating protocol execution parameters. Databases store connection information between the objects and protocol conversion functions. A protocol conversion unit interfaces first protocol execution unit and the megaco protocol execution unit, and searches for destination objects and the protocol conversion functions in the database, and converts the generated protocol execution parameters to protocol types of the destination objects, based on condition modes of objects which transmitted the protocol packets.

摘要： An apparatus, electronic apparatus and method for adjusting jitter buffer is provided. A previous jitter buffer size based on a jitter buffer size determined according to an adaptive jitter buffer size calculation algorithm is applied in predicting a jitter buffer size of future time such that the predicted jitter buffer size is applied to obtain a jitter buffer size of a valid time. The audio quality of the speech transmitted over a packet switched network is enhanced.

摘要： Disclosed is a system and method for expandibly operating protocol PDU (Protocol Data Unit) encoding/decoding blocks communicating with a protocol executing block in the same protocol. With at least two types of protocol PDU encoding/decoding blocks for data communication in the same protocol, the protocol executing block does not implement the execution of protocol PDUs independently according to the respective encoding/decoding methods, but converts the information of the protocol PDU encoding/decoding block into that of the protocol executing block using a protocol PDU common data structure disposed between the protocol PDU encoding/decoding blocks and the protocol executing block.
