example 1

[0110] Figure 12 It is a flow chart of Example 1 according to the embodiment of the present invention. Such as Figure 12 As shown, the first example mainly includes the following processing (step S1201-step S1205):

[0111] Step S1201: The MTU (Maximum Transmission Unit) of the IP protocol layer between peer GTP-Us is dwMTU, and wSegMaxSize=(dwMTU-20-byHeaderSize) is preset, wherein wSegMaxSize is the preset threshold configured in the background, and 20 is the IP protocol Header size, byHeaderSize is the above GTP-U data header size;

[0112] Step S1203: Fragmenting the GTP-U data packet by using the data packet fragmentation method;

[0113] Among them, the above fragmentation method can be found in image 3 The description in , will not be repeated here.

[0114] Step S1205: After transmitting the fragmented GTP-U data to the IP layer, since each data fragment is within the dwMTU range, the IP protocol layer does not perform fragmentation any more.

[0117] Figure 13 It is a flow chart of Example 2 according to the embodiment of the present invention. Such as Figure 13As shown, the second example mainly includes the following processing (step S1301-step S1305):

[0118] Step S1301: The size of the data packet delivered by the PDCP or the application layer to the GTP-U is wDataSize, wherein wDataSize is greater than 65535 bytes and less than or equal to 9133025 (65535×15) bytes;

[0119] Step S1303: set wSegMaxSize=65535, and use the packet fragmentation method to fragment the GTP-U data packet. After processing, the payload of each fragment is less than or equal to 65535;

[0120] Among them, the above fragmentation method can be found in image 3 The description in , will not be repeated here.

[0121] Step S1305: After receiving the fragmented data, the peer GTP-U entity reassembles according to the reassembly method, and reassembles each data fragment into a complete data packet, wherein the size of the data packe...

[0125] Figure 14 It is a flow chart of Example 3 according to the embodiment of the present invention. Such as Figure 14 As shown, the second example mainly includes the following processing (step S1401-step S1405):

[0126] Step S1401: flexibly configure the GTP-U segment length wSegMaxSize through background OAM (Operation And Management);

[0127] Step S1403: Use the fragmentation method to perform GTP-U data fragmentation processing, and each data packet fragmentation after processing is less than or equal to wSegMaxSize;

[0128] Among them, the above fragmentation method can be found in image 3 The description in , will not be repeated here.

[0129] Step S1405: After receiving the fragmented data, the peer GTP-U entity reassembles according to the reassembly method, and reassembles each data fragment into a complete data packet.

[0130] Among them, the above-mentioned recombination method can be found in Figure 4 The description in , will not be repeated here...

Abstract

The invention discloses a method for sending, receiving and transmitting data packets and a device therefor. In the transmission method, a GTP-U data packet is divided into multiple packet fragments; attribute information of each data packet fragment is added to the data packet fragment; one or more data packet fragments with attribute information added are sent each time; multiple data packet fragments are received to respectively obtain the attribute information carried by each data packet fragment; the received data packet fragments belonging to the same GTP-U data packet are combined to obtain the data packet according to the attribute information of each data packet fragment. According to the technical proposal of the invention, size of the GTP-U data packet can be flexibly controlled, data packet (data payload) capacity of data packets the sending of which is supported by the GTP-U can be expanded.

Description

technical field [0001] The present invention relates to the communication field, in particular to a data packet sending and receiving method. Background technique [0002] The separation of the electronic product code (Electronic Product Code, EPC) network control plane and the user plane and the trend of flattening the user plane are also an inevitable choice to deal with the surge of network traffic. The throughput capacity of the user plane has gradually become the main bottleneck of the mobile packet network equipment serving the general packet radio service support node (Serving General packet radio service support node, referred to as SGSN) and the GPRS network management support node (Gateway GPRS Support Node, referred to as GGSN), At the same time, it also leads to the rapid growth of investment in the packet core network. Therefore, there is an urgent need to optimize the current user plane performance. [0003] The GPRS Tunneling Protocol User Plane (User plane ...
