Below in conjunction with different embodiment, describe transmitting terminal and send the precedence information of user message to receiving terminal by different modes.
Wherein, among Fig. 3 and the embodiment shown in Figure 5, transmitting terminal sends the precedence information of user message to receiving terminal by transport stream.
As shown in Figure 3, transmitting the user message method comprises in the processing of transmitting terminal:
301, the priority of transport stream in the flow transmission control protocol is set;
Before transmitting terminal SCTP unit transmitted user message, transmitting terminal upper-layer protocol unit was provided with the priority of transport stream by transmitting terminal SCTP unit.In concrete operations, transmitting terminal upper-layer protocol unit sends message to transmitting terminal SCTP unit, and notice transmitting terminal SCTP unit is provided with the priority of transport stream.In the transport stream that can have between two SCTP endpoint more than two, transmitting terminal SCTP unit is provided with a priority for each transport stream, such as the priority that transport stream 0 is set is 1, the priority that transport stream 1 is set is 2 or the like, and priority is that to be higher than priority be 2 transport stream to the priority of 1 transport stream.After the priority of transport stream is set, transmitting terminal SCTP unit is when transmitting user message, according to the priority of transport stream from high to low, the preferential user message that transmits in the high priority transfer stream, transmit the user message in time high priority transfer stream again, transmit the user message in the lowest priority transport stream at last.
302, transmit the priority of transport stream to receiving terminal by the flow transmission control protocol;
After transmitting terminal SCTP unit set the priority of transport stream, transmitting terminal SCTP unit sent the precedence information of transport stream to receiving terminal SCTP unit by INIT (initial, initial) data block.At this moment need to expand the optional parameters in the INIT data block of existing protocol, carry the precedence information of transport stream by this optional parameters.Types value with this optional parameters in the embodiment of the invention is made as 21, and the types value of optional parameters can be made as other does not in actual applications have occupied value.。
As shown in Figure 4, be the INIT optional parameters after the expansion, each row of this optional parameters has 32 bits, and preceding 16 bits of first row represent that the types value of this optional parameters is the shared byte numbers of 21, the first row back these optional parameters medium priority information of 16 bit identification.Preceding 16 bits of second row are represented the priority of transport stream 0, and the second row back, 16 bits are represented the priority of transport stream 1, and preceding 16 bits of the third line are represented the priority of transport stream 2, by that analogy.Like this in actual transmissions, the types value of 1～2 byte representation of optional parameters self, the shared byte number of 3～4 byte representation precedence informations, per two bytes are carried the precedence information of a transport stream in other the byte.
In transmitting terminal SCTP unit after receiving terminal SCTP unit transmits the precedence information of transport stream, receiving terminal SCTP unit sends INIT ACK (Acknowledge Character to transmitting terminal SCTP unit, acknowledge character) data block, include optional parameters in this data block, the structure of optional parameters as shown in Figure 4, receiving terminal SCTP unit sends to transmitting terminal SCTP unit by this optional parameters with the precedence information of the transport stream of receiving terminal, inform the precedence information of the transport stream of this direction from the receiving terminal to the transmitting terminal, when transmitting terminal sends user message, need use the precedence information of transport stream in the INIT ack msg piece at receiving terminal.
