According to the corresponding relation of data channel and buffer address, determine that the data channel shared by described business data transmission corresponds to
Buffer address, and by described business datum write determine the corresponding buffer area of buffer address；
When first sets duration and reach, read from buffer area in the described first business datum setting write in duration, and
To the business datum IPization reading, and described business datum is determined according to the corresponding relation between data channel and udp port
The shared corresponding udp port of data channel of transmission, and set up between the udp port using described determination and operational processor
UDP link, the business datum after IPization is sent to operational processor by the UDP link set up；
Data combiners block, for entering the signaling data receiving and business datum according to the discernible data form of core net
Send to core net after row synthesis encapsulation.
12. equipment as claimed in claim 11 are it is characterised in that described equipment also includes：
Timing writing module, after receiving, in business datum receiver module, the IPization business datum that operational processor sends,
Before signaling data and business datum are carried out synthesis encapsulation by Data Synthesis module, the business datum of reception is deposited in the buffer
Storage the second setting duration, described second sets duration is determined by receiving the data rate of business datum.
