Description
Technical field
The present invention relates to a kind of portable terminal, particularly relate to a kind of support TCP/IP portable terminal that can effectively transmit data.
Background technology
After second generation communication, have up till now a lot of services provider for multiple mobile communication service is provided hard thought to the user.To utilize basic Internet service in order providing, to introduce the portable terminal of supporting TCP/IP at this.But existing portable terminal exists as built on stilts problem.
Following with reference to the problem points of description of drawings to the portable terminal of support TCP/IP.
Fig. 1 is the pie graph of the existing TCP head of expression portion.
As shown in the figure, the head of the Transmission Control Protocol that existing portable terminal uses is defined as RFC793, is used for being fit to wired internet basically.This existing Transmission Control Protocol is an IP network, promptly is made up of well-regulated structure in order to satisfy the interchangeability between each server in the Internet.That is, constitute by territory for the big or small sequence number of 65536 ports, 32 bits that send and receive.Below specify.
1. source port number (Source port number (16)): the portal number of transmit leg;
2. destination port number (Destination port number (16)): recipient's portal number;
3. sequence number (Sequence number (32)): the sequence number that receives packets of information;

Constitute according to TCP head of the present invention portion as stated and make above-mentioned TCP head built on stilts minimum, make that the built on stilts maximization with minimum utilizes Radio Resource in user's transmitting and receiving data.At this moment; Sequence number replaces as existing 32 bit lengths and use 16 bit lengths, because of between terminal and transponder than short path (jump of minority (hop)), thereby do not have the confusion of sequential; The repetition sequential of terminal room is below 122 segments, so normal transmitting and receiving data.Therefore normal transmitting and receiving data.Therefore, even whether normally also will be careful transmitting and receiving data through as above step.
And general TCP/IP head is compressed and sends reception through the header decompression will algorithm, also can be compressed and be transmitted according to compression algorithm according to the situation to the TCP head of its motion of the present invention.Detailed content for compression algorithm can cause indeterminate main idea of the present invention, does not therefore describe at this.
Fig. 3 is according to the TCP header information mapping table between the TCP head portion that dwindles of the embodiment of the invention and existing TCP head portion.
As shown in the figure, during above-mentioned TCP header information mapping table TCP head of dwindling used according to the invention as shown in Figure 2, be for existing TCP header information mapping.If existing tcp port number is that the tcp port number that dwindled in 21 o'clock is No. 1, if the tcp port number that existing TCP number dwindled when being No. 25 is No. 3.So portal number all is suitable in transmitting terminal slogan and receiving port number.
In addition, though do not illustrate among the figure, and above-mentioned TCP header information mapping table also can be represented the confirmation of receipt sequence number (Acknowldedge Sequence Number) that above-mentioned portal number is outer.
Fig. 4 is the concise and to the point figure that representes data flow according to the embodiment of the invention through the TCP head of dwindling.
With reference to Fig. 4, can know that according to the present invention the TCP head that the portable terminal utilization is dwindled transmits data, transponder is changed above-mentioned TCP head of dwindling and transmit with existing TCP head.This is explained in more detail which kind of TCP head portable terminal decision then according to the present invention uses, and according to above-mentioned decision the TCP head can be set.At this moment, above-mentioned decision can utilize the IP address to decide according to embodiments of the invention.That is, can whether use according to the IP head of dwindling that another specification of the IP subnet mask or the inventor is put down in writing and decide.
In addition, when the TCP head in the data that receive in the transponder of receiving terminal is the head of dwindling, can determine whether this is changed with the TCP head.That is, above-mentioned transponder utilizes the IP head of putting down in writing in IP subnet mask or another specification according to the above-mentioned inventor of dwindling whether to use to determine.That is, as shown in the figure, when needing to use existing TCP head to be sent to the Internet, the TCP head that will dwindle is carried out transfer after converting existing TCP head into.So series of processing steps can be exchanged into existing high-speed procedure, is the item that will state the party at this.
In addition, be made up of existing TCP head when the Internet is sent to mobile terminal data, transponder receives its data transaction and becomes aforesaid TCP head of dwindling and send portable terminal to.
In addition, when the data that above-mentioned transponder will receive from the Internet are sent to portable terminal, can directly be sent to portable terminal without aforesaid TCP head conversion.So under the situation, generally use the phone of portable terminal to connect the network service, the device of its corresponding TCP/IP stratum is the PC that connects of the phone of transponder whether just.In such cases, do not need the head switch process.
