Description
Technical field
The present invention relates to a kind of Internet protocol sharding method and related radio network system, but particularly relevant for a kind of Internet protocol sharding method of improving data transmission efficiency and related radio network system.
Background technology
Along with development in science and technology, network application is also more and more universal, the user can utilize the electronic installations such as desktop PC, mobile computer, personal digital assistant (personal digital assistant, PDA) or smart mobile phone to be linked to the internet at any time.In Radio Network System, can adopt different communication protocol to carry out transfer of data between transmitting terminal and receiving terminal, and it is correct in order to ensure transfer of data, each its size of maximum data package that transmits can not surpass the maximum transfer unit (maximum transmission unit, MTU) of communication protocol.
Fig. 1 is the functional block diagram of a Radio Network System 100 in prior art.The 2nd figure is the schematic diagram of the Radio Network System 100 of prior art when adopting special communication protocols to carry out transfer of data.The transmitting terminal of Radio Network System 100 comprises that one cuts unit 10, and the receiving terminal of Radio Network System 100 comprises a recomposition unit 20, and PK 1-PH3 represents the data packets of different sizes.The size of tentation data package PK 1 equals the maximum transfer unit MTU of special communication protocol, and prior art can directly be sent to receiving terminal from transmitting terminal with data packet PK 1, and can reach unit of transfer's utilization rate of maximum 100%; The size of tentation data package PK2 surpasses the maximum transfer unit MTU of special communication protocol, the cutter unit 10 of prior art needs first data package PK2 to be carried out Internet Protocol cutting (IP fragmentation), and then data packet PK2 is cut into two than being resent to receiving terminal after boy's Datagram PK21 ' and PK22 ', that is data packet PK2 need transmit at twice, and possibly can't reach peaked unit of transfer utilization rate when transmitting package PK22 '; Suppose that the size of package PK3 is no more than the maximum transfer unit MTU of special communication protocol, prior art can directly be sent to receiving terminal from transmitting terminal with data packet PK3, but possibly can't reach peaked unit of transfer utilization rate.
In the prior art, if the cutter unit of transmitting terminal 10 carries out too many Internet Protocol cutting, the recomposition unit 20 of receiving terminal need expend more resources and come the recon data packet.Simultaneously, when data packet differed in size maximum transfer unit in special communication protocol, prior art can't provide 100% maximum transfer unit utilization rate, therefore can waste Internet resources.
Summary of the invention
Because the problem of above-mentioned prior art, purpose of the present invention is exactly a kind of Internet protocol sharding method and related radio network system are provided, with improving data transmission efficiency.
For reaching above-mentioned purpose, the invention provides a kind of method of carrying out the Internet protocol burst in a Radio Network System, its transmitting terminal that is included in this Radio Network System is merged into a data packet string with a plurality of data packets; One maximum transfer unit of a communication protocol that adopts according to this Radio Network System is cut into a plurality of subdata packages with this data packet string; And this transmitting terminal will these a plurality of subdata packages be sent to a receiving terminal of this Radio Network System.
The present invention separately provides a kind of Radio Network System that carries out the Internet protocol burst, and it comprises a transmitting terminal and a receiving terminal.This transmitting terminal comprises a merge cells, is used for a plurality of data packets are merged into a data packet string; And a cutting unit, be used for a maximum transfer unit of the communication protocol that adopts according to this Radio Network System this data packet string is cut into a plurality of subdata packages.This receiving terminal comprises a recomposition unit, these a plurality of subdata packages that this transmitting terminal that is used for recombinating transmits.
Advantage of the present invention is for promoting the data transmission efficiency of Radio Network System when carrying out the Internet protocol burst.

Embodiment
Fig. 3 is the functional block diagram of a Radio Network System 300 in the present invention.Fig. 4 is the schematic diagram of Radio Network System of the present invention 300 when adopting special communication protocols to carry out transfer of data.Radio Network System 300 can adopt multi-layer open system interconnection (open system interconnection, OSI) the network architecture, be sequentially physical layer (physical layer) from ground floor of the end to the highest layer 7, data link layer (data link layer), network layer (network layer), transport layer (transport Layer), session layer (session layer), presentation layer (presentation layer) and application layer (application layer).Radio Network System 300 comprises a transmitting terminal and a receiving terminal, transmitting terminal and receiving terminal can be respectively user's device (user equipment, UE) or one base station (base station, BS) different levels, or be respectively a specific level of user's device and a specific level of a base station, adopt each other special communication protocol to carry out transfer of data.
In Radio Network System 300 of the present invention, transmitting terminal and receiving terminal can adopt Ethernet (Ethernet) agreement, token ring (Token-Ring) agreement, Fiber Distributed Data Interface (Fiber Distributed Data Interface, FDDI) agreement, transmission control protocol (Transmission Control Protocol, TCP), or User Datagram Protocol (User Datagram Protocol, UDP) etc.
In the present invention, the transmitting terminal of Radio Network System 300 comprises cutting unit 10 and a merge cells 30, and the receiving terminal of Radio Network System 300 comprises a recomposition unit 20.PK1-PHn represents the data packet of different sizes, can be application program package, agreement package or service quality (QoS) package.
As shown in Figure 4, the relative size relation between the maximum transfer unit MTU of data packet PK1-PKn and special communication protocol no matter, merge cells of the present invention 30 can be merged into a data packet string PK (as shown in arrow S1) with data packet PK1-PKn at transmitting terminal, then carries out Internet Protocol cutting by 10 couples of data package string PK of cutter unit a plurality of subdata package PK1 '-PKm ' (as shown in arrow S2) is provided.After being sent to receiving terminal (as shown in arrow S3), can carry out data recombination by recomposition unit 20.
The present invention can improve the maximum transfer unit utilization rate.For instance, if the size of data packet string PK is the integral multiple of maximum transfer unit MTU, the size of subdata package PK1 '-PKm ' all equals maximum transfer unit MTU, so each subdata package can transmit with 100% maximum transfer unit utilization rate; If the size of data packet string PK is not the integral multiple of maximum transfer unit MTU, only there is the size of sub-Datagram PKm ' can be less than maximum transfer unit MTU in subdata package PK1 '-PKm ', therefore each subdata package can transmit with 100% maximum transfer unit utilization rate except subdata package PKm ', and whole maximum transfer unit utilization rate also can be near 100%.
In sum, the present invention can avoid reducing whole maximum transfer unit utilization rate when carrying out the Internet protocol burst, makes Radio Network System to come the transmission of data package with better efficient.The above is only the preferred embodiments of the present invention, is not limited to the present invention, and for a person skilled in the art, the present invention can have various modifications and variations.Within the spirit and principles in the present invention all, any modification of doing, be equal to replacement, improvement etc., within all should being included in protection scope of the present invention.Within the spirit and principles in the present invention all, any modification of doing, be equal to replacement, improvement etc., within all should being included in protection scope of the present invention.
