Description
Technical field
The present invention relates to the network communications technology, particularly a kind of method of transfer of data, system and equipment.
Background technology
In System Architecture Evolution/Long Term Evolution of future generation (System Architecture Evolution:SAE/Long Term Evolution:LTE) network, in order to finish the routing addressing function better, and minimizing message time delay, remove the network layer in the conventional telecommunications net, application layer is directly placed on the transport layer SCTP (Stream Control Transmission Protocol:SCTP), utilize internet protocol (IP) layer to finish routing addressing function in transmission control protocol/internet protocol (TCP/IP) network.
Have SCTP endpoint at the SCTP layer, this end points is the logic transmitting-receiving person of SCTP data block, and each SCTP endpoint is by a port numbers and one group of IP address unique identification.Current, adopt the SCTP coupling to finish transfer of data in the IP network, so-called SCTP coupling is exactly to be based upon two connections between the SCTP endpoint.SCTP adopts socket (socket) mechanism to come coupling is set up and monitored, and generally will receive an end that connects and be defined as service end, and the end that will initiate to connect is defined as client.
Each SCTP coupling comprises a plurality of unidirectional streams and transmits data.
Set up in the process in the SCTP coupling, service end is monitored the port numbers of upper layer application, waits for the connection request of client.Client sends the SCTP coupling request of connecting according to the port numbers of destination, after message wraps in the purpose IP address arrival SCTP destination of IP layer by coupling, giving the SCTP layer of service end handles, the SCTP layer is given corresponding monitor process according to the destination slogan in the data block head and is handled, thereby finish the process of setting up of SCTP coupling, after coupling was set up and finished, upper layer application was obtained the sign of corresponding SCTP coupling.During data transmit-receive was handled, the transmitting terminal upper layer application sent to the SCTP layer according to SCTP coupling sign with data block and handles; The SCTP layer of receiving terminal sends to upper layer application according to the sign of this coupling with the data block of receiving and finishes further processing.
The connection of present SCTP coupling and maintenance are to utilize the port numbers of upper-layer protocol stack to finish, and utilize corresponding port number to carry out the distribution processor of message.Along with progressively going deep into that SCTP uses, a plurality of upper-layer protocol stacks can occur and be carried on the sight that SCTP goes up and opposite equip. communicates.
As shown in Figure 1, the schematic diagram of prior art SCTP coupling, each upper-layer protocol stack utilization is distributed to self port numbers and opposite end and is set up an independent SCTP coupling.
Signaling hop 3 user adaptation layers at two ends (Message Transfer Part 3 User AdaptationLayer:M3UA) are set up a SCTP coupling based on the port numbers 2905 that internet number assignment tissue (IANA) distributes.
The diameter layer (Diameter) at two ends is set up a SCTP coupling based on the port numbers 3868 that IANA distributes.
Existing treating method to the SCTP coupling, need set up independent SCTP coupling at each upper-layer protocol stack, and it is safeguarded, continuous increase along with the upper-layer protocol stack, must need to take a large amount of resources, such as: IP address, port numbers etc. can increase the difficulty of maintenance simultaneously greatly, and can not well utilize the characteristics of IP network high bandwidth.
As shown in Figure 2, the SCTP data block comprises: type (Type), reservation (Reserved), length (Length), transmission sequence number (Transmisson Sequence Number:TSN), traffic identifier (StreamIdentifier), Stream Sequence Number (Stream Sequence Number), payload protocol-identifier (PayloadProtocol Identifier:PPI) and user data (User Data).
After the SCTP coupling, transmitting terminal is saved in user data in the data block, sends to receiving terminal.
In sum, at present in the SAE/LTE network, two equipment rooms need be set up many SCTP couplings, thereby taken a large amount of resources, increase the difficulty of safeguarding, and can not well utilize the characteristics of IP network high bandwidth, and the PPI field only is used for transmitting upper-layer protocol stack numbering, causes the wasting of resources.
