Description

A kind of signal transmission method and equipment

Technical field

The present invention relates to field of communication technology, in particular to a kind of signal transmission method and equipment.

Background technique

With the development of communication technology, more and more terminals need to be linked into wireless network, communication is also no longer limited to interpersonal communication, machine type communication (Machine Type Communication, abbreviation MTC) technology realizes the communication (Machine to Machine) of machine and machine, also becomes to become increasingly popular.In the 5th current third generation mobile communication network demand, low-power, low cost and the Connection Density of MTC terminal (terminal i.e. in MTC communication) covered greatly reach 200000/km², and the data volume that these MTC terminals communicate every time is fewer, the commitment defini interval of some MTC terminals is also long.

Still there is part MTC terminal using transmission control protocol (Transmission Control Protocol in MTC communication, TCP)/Internet Protocol (Internet Protocol, IP), this just needs first to establish TCP connection before transmitting the data, data transfer and then discharge established TCP connection.In TCP connection establishment process, originating end uses TCP message, three-way handshake process is carried out by network side and destination, to complete the foundation with the TCP connection of destination, the structure of TCP message is as shown in Figure 1, including IPV4 header, TCP header and data, TCP and IPV4 header occupy 40 bytes (byte) in total.TCP header is contained in TCP message used in TCP connection foundation and release process.The process of the foundation of TCP connection is as shown in Figure 2, originating end by with domain name system (Domain Name System, abbreviation DNS) interaction, the IP address of destination is got, then, originating end passes through network side, it initiates TCP and establishes three-way handshake process, wherein, network side is responsible for the TCP message for sending originating end, passes through destination.It is specific as follows:

First, originating end sends message segment 1 by the lateral destination of network, the port of destination is carried in the message segment 1, and the TCP initial sequence number ISN of originating end, SYN=1 in the message segment, seq=i is arranged in ACK=0, data sequence number, and seq=i is the TCP initial sequence number (i.e. ISN) of selection.TCP regulation, the message segment of SYN=1 cannot carry data, but consume a serial number.

Then, destination returns to the message segment 2 of the TCP initial sequence number comprising the destination in response by network side.Wherein, the ISN that the acknowledged sequence number in message segment 2 is set as originating end adds 1, the SYN=1 in message segment 2, ACK=1, acknowledged sequence number ack=i+1, and data sequence number is set as seq=j, and seq=j is that selection TCP initial sequence number seq=j, a SYN will occupy a serial number.

Finally, originating end is by network side returned packet section 3 as confirmation.Wherein, the ISN that the acknowledged sequence number in message segment 3 is set as destination adds 1, ACK=1, and acknowledged sequence number ack=j+1, data sequence number is set as seq=i+1.

During TCP connection release, originating end uses TCP message, carries out 4-Way Handshake process by network side and destination, to complete the release with the TCP connection of destination, as shown in figure 3, wherein, network side is responsible for the TCP message for sending originating end, passes through destination.Detailed process is as follows:

Firstly, originating end sends message segment 4 by the lateral destination of network, and stops transmitting with the data of destination, TCP connection is actively closed.FIN=1 in message segment 4, data sequence number seq=u, the data sequence number are that the serial number of the last byte of the data transmitted adds 1.

Then, destination passes through network side returned packet section 5, and ACK=1, acknowledged sequence number ack=u+1, data sequence number seq=v in the message segment 5, which is that the serial number of the last byte of the data transmitted adds 1.

Then, if destination sends message segment 6, FIN=1, acknowledged sequence number ack=u+1, data sequence number seq=w in the message segment 6 by the lateral originating end of network without the data for needing to send to originating end.

ACK=1, acknowledged sequence number ack=w+1, data sequence number seq=u+1 finally, after originating end receives message segment 6, by network side returned packet section 7, in the message segment 7.

It can be seen that in TCP message used in TCP connection foundation and release process from the content, even if some information are sky in TCP header, the byte of corresponding length can be also occupied, to cause the waste of interface-free resources.

A kind of method that possible reconstruct TCP/IP header structure is given below, specific as follows:

1, in TCP header SYN/FIN recovery:

It is 1 when network side or the first equipment receive radio open signaling and needs to restore that SYN or FIN is then arranged when TCP foundation perhaps discharges corresponding TCP header in the TCP header of construction, is otherwise provided as 0.

2, the recovery of the data sequence number in TCP header:

If in the TCP header currently restored when SYN=1, the data sequence number in TCP header is the initial sequence number carried in radio open signaling or is the initial sequence number generated at random (when in radio open signaling without carrying initial sequence number)；

Otherwise:

If be SYN=1 in the preceding TCP header once restored, data sequence number is the data sequence number+1 of the preceding TCP header once restored in the TCP/IP header that currently restores；Otherwise data sequence number is (size of data carried in TCP/IP message belonging to data sequence number+preceding TCP header once restored in the preceding TCP header once restored) % (2 in the TCP header currently restored³²)；

4, the recovery of the mark in IP header: it is only intended to indicate be currently which packet due to the mark in IP header, the main purpose of the mark is the scene of section of calling the score for IP.When the network equipment reconstructs TCP/IP header, since upstream data packet only passes through the side the first equipment (such as UE), IP packet will not be segmented, so need to only be set as (last mark+1) % (2¹⁶), first mark can be random The number generated (in effective range).When the first equipment reconstruction TCP/IP header, since network side has the function of TCP/IP layer, so network side can be then forwarded to the first equipment after all same IP packets all reach, so need to only be set as (last mark+1) % (2¹⁶), first mark can be the number generated at random (in effective range)；

5, the recovery of the acknowledged sequence number in TCP header (ACK SN) and confirmation field (ACK):

In addition to setting confirmation field (ACK) is 0 in the step 1 in TCP connection Establishing process, setting confirmation field (ACK) is 1 under other conditions.

For TCP connection Establishing process TCP ACK message (the TCP ACK constructed including the network equipment and UE), ACK SN is set as (initial sequence number+1 carried in radio open signaling) % (2³²)。

The TCP ACK message of network equipment side structure in TCP ACK message (i.e. the TCP ACK of Network Device Construction) corresponding for downlink data packet and TCP release process, the network equipment is generated according to rlc layer ACK or physics (PHY) layer ACK situation, i.e. the network equipment is known which packet transmission is correct, which packet is correct without transmission, then the network equipment can generate TCP/IP ACK to opposite end according to these situations, wherein, ACK SN is set as the corresponding byte number of ordered data packet that the network equipment has correctly been sent；Or, the network equipment saves the downlink data packet received, directly to opposite end send TCP layer ACK SN and ACK (i.e. without etc. wireless sides correctly transmit, when subsequent wireless side error of transmission, the network equipment is directly retransmitted in wireless side), wherein, ACK SN is set as the network equipment correct orderly corresponding byte number of received TCP data packet.

The TCP ACK message of UE side structure in TCP ACK message (i.e. the TCP ACK of UE side structure) corresponding for upstream data packet and TCP release process, first equipment (such as UE) is generated according to rlc layer ACK in wireless protocols or PHY layer ACK situation, rlc layer or PHY layer are known which packet transmission is correct i.e. in wireless protocols, which packet is correct without transmission, therefore, the first equipment can (ACK SN be set as the corresponding byte number of ordered data packet that wireless protocols have correctly been sent according to these situations generation TCP/IP ACK.
