In the existing cdma system, the TCP/IP business adopts two kinds of methods in that the realization of air interface is general: a kind of is to set up fixedly connectedly, promptly takies fixing Radio Resource.As in the CDMATDD system, after the user applies TCP/IP business, system may distribute to this user with the code channel of an ascending time slot and the code channel of a descending time slot respectively, is used for the transmission of TCP/IP business, until this end of service.Another kind is that grouping connects, i.e. the form of datagram shared channel.This moment, a plurality of users' IP datagram was shared a channel.Because data service has sudden and non real-time, the efficient height that the efficient that grouping connects connects than conventional fixed.But when little and transmission frequency was high again when packet, grouping connected and will transmit a large amount of signalings on air interface for establishment of connection each time.So the spectrum efficiency of these two kinds of methods on air interface is not high.Again because their transmission all is based on IP datagram, though can carry out header-compressed, but (the following MS that also is called for short) will decompress at portable terminal, and will carry out the processing procedure of complicated ICP/IP protocol bunch, and everything all makes the MS service processing function complicated more.So, adopt mode to realize that the TCP/IP business of MS is unfavorable based on IP datagram at air interface.In fact, because MS can not the also unnecessary disposal ability that possesses computer, it is in the support voice business, only limit to limited several aspects such as Email, online browsing, ecommerce for data service, this obviously is unaccommodated for the TCP/IP transmission means that designs for different operating system, different application.
Summary of the invention
The object of the present invention is to provide a kind of method that in the portable terminal of code division multiple address communication system, realizes the TCP/IP business, the wherein processing of the not responsible ICP/IP protocol of MS bunch, wireless access network (Radio AccessNetwork is initiated and ends in the processing of ICP/IP protocol bunch, below also be called for short RAN) in the MS agent application, MS comprises the reflection of application program among the RAN, in the TCP/IP business, MS and RAN transmit the application program image data and transmission of IP data newspaper not on air interface.
Preferably, the air interface Radio Resource is periodic transfer application program image data with the time period of fixed length, and according in each current transmission cycle data quantity transmitted being redistributed the air interface Radio Resource.
The invention has the advantages that, MS needn't possess the disposal ability of ICP/IP protocol bunch just can enjoy the TCP/IP service, the technology of ICP/IP protocol bunch is used and air interface is separated, thereby improved the spectrum efficiency of TCP/IP operational space interface, simplified travelling carriage simultaneously again for supporting the professional required equipment complexity of TCP/IP.
Brief Description Of Drawings
For making purpose of the present invention, scheme and advantage clearer, below especially exemplified by preferred embodiment and the present invention is described in more detail in conjunction with the accompanying drawings.
Fig. 1 is in first preferred embodiment of the present invention, the realization theory diagram of the TCP/IP business of MS;
Fig. 2 is in second preferred embodiment of the present invention, and the down link IP datagram is to the realization schematic diagram in dynamic data pond;

Implement mode of the present invention
Thought of the present invention is, set up the agency of MS application program in wireless access network RAN, and MS only comprises the reflection of agent application among the RAN.The TCP/IP business initiates or ends at the MS agent application among the RAN according to the demand of MS, just only need the transfer application Image Data like this on air interface, the technology of ICP/IP protocol bunch is used and air interface is separated.
Preferably, the air interface Radio Resource is periodic transfer application program image data with the time period of fixed length, and according in each current transmission cycle data quantity transmitted being redistributed the air interface Radio Resource.Preferably, the described cycle can be the integral multiple of code division multiple access system physical frame.
Preferably, in described RAN He among the described MS, establish application program image dynamic data pond, the application programs Image Data are stored, MS and RAN transmit the application program image data and transmission of IP data newspaper not on air interface, for down link, be the application program image dynamic data pond of distributing to specific MS among the RAN with this MS between be connected; For up link, it is being connected between corresponding Application Agent access point among application program image dynamic data pond and the RAN among the MS.
Preferably, described dynamic data pond comprises two storage areas at least, and each user who carries out the TCP/IP business service has the corresponding dynamic memory block respectively at these two storage areas; Described two storage areas are that cycle wheel stream transmits data by air interface to MS with the time period of fixed length, and store the data of preparing in next periodic transfer, the air interface Radio Resource is redistributed according to institute's data quantity stored in the storage area of each current transmission.
Please refer to accompanying drawing 1, this accompanying drawing is in first preferred embodiment of the present invention, the implementation theory diagram of the TCP/IP business of MS in cdma system.In cdma system, ICP/IP protocol bunch stops or originates from the agency of MS application program among the RAN, and MS then need comprise the reflection of application program among the RAN.For down link, the processing of the ICP/IP protocol of MS bunch ends at the agent application among the RAN and is converted into the application program image data.All application program image data are stored (being stored in the dynamic data pond) by RAN, use that the air wireless interface agreement is finished and MS between transfer of data.For up link, the application program image data that arrive RAN from MS will send with the form of IP datagram, are RAN as the promoter, and just the source address of usefulness is the IP address (being distributed by RAN) of this MS.
The realization of TCP/IP business just can be divided into two stages like this: stage is the business realizing between MS agent application and IP network among the RAN, bunch carries out by ICP/IP protocol.Another stage is the business realizing between RAN agent application and MS application program image, and implementation method is different and different according to application program and MS disposal ability.The transmission of this phase data is that the Access Layer by the cyberspace interface carries out, and its reliability, confidentiality are guaranteed by the air interface agreement of cdma system.
RAN is connected with the air interface about the TCP/IP business of MS, no longer is based on to transmit the connection of IP according to newspaper: for down link, be the application program image data pool of distributing to specific MS among the RAN with this MS between be connected; For up link, it is being connected between corresponding Application Agent access point among application program image data pool and the RAN among the MS.The load mode of data is realized by the Access Layer definition of air interface.
RAN is connected with other IP network, and employed TCP/IP relevant technologies and air interface are irrelevant.The distribution of the IP address of MS, management, move etc., all finished by RAN, MS does not need to possess the disposal ability of any relevant ICP/IP protocol bunch.
In RAN, have dynamic memory (being the dynamic data pond) respectively at different mobile subscribers, a dynamic memory is also arranged in MS, the size of memory in the cycle that the air interface dynamics of channels is distributed, reaches the management method decision by the wireless network data capacity.
No matter be in RAN, still in MS, all carry out data compression when the application program image data deposit the dynamic data pond in possibly, decompress accordingly again the opposing party through behind the air interface.Compression may have multiple form according to the difference of application program.
This patent is particularly useful for CDMA TDD system.
Characteristics sudden, non real-time that the TCP/IP business has.According to non real-time, the storage of application program image data is to carry out in the cycle, and the cycle is generally got the integral multiple of cdma system physical frame.According to sudden, the air interface Radio Resource is chronomere with the memory cycle, redistributes according to the current data amount that the dynamic data pond is stored, and is equivalent to each memory cycle organize once fixedly connected.Can make like this that Radio Resource obtains fully, reasonable use.Because the data that transmit do not comprised the information of relevant data newspaper header in the ICP/IP protocol bunch, so utilization ratio of wireless resources is further enhanced.
Fig. 2 is in second preferred embodiment of the present invention, and the down link IP datagram is to the realization schematic diagram in dynamic data pond, and for down link, IP datagram can realize with the flow process of Fig. 2 to the application program image data pool.
Fig. 2 (1) is unit with the IP datagram, transmits and handles according to the IP agreement.
Fig. 2 (2) bunch carries out the processing of network layer and transport layer according to ICP/IP protocol, and the agent application in RAN provides service.
Fig. 2 (3) produces the application program image data by agent application.The application program image data can be the visual interfaces of application program, also can be the special data stream that defines between application program image in Application Agent and MS, and its generating mode can change with the different of MS disposal ability with application program.As: MS has carried out video request program on the net at Internet, the video data that Application Agent among the RAN transmits from network by ICP/IP protocol bunch reception, this video data may carry out Data Format Transform before depositing the application program image data pool in, to adapt to the player (may be hardware) among the MS.MS need not possess the disposal ability of ICP/IP protocol bunch like this, does not need the complicated operations system, just can enjoy specific TCP/IP business service.This process is separated general ICP/IP protocol bunch and air interface, makes different vendor provide required business at air interface to MS as required.
Fig. 2 (4) application program image data may be compressed, and deliver to the dynamic data pond afterwards.The dynamic data pond is divided into A and B two parts, and each user who carries out the TCP/IP business service has the corresponding dynamic memory block at A and B respectively.When the data of A were being transmitted by air interface, the storage from IP network was among B.When the data of B were being transmitted by air interface, the storage from IP network was among A.
Data in Fig. 2 (5) dynamic data pond reach MS periodically by air interface.Periodic process is as (4).So in each cycle, are the contents of storing in the dynamic data pond last one-period in the data that air interface transmitted, data volume is known definite value.
Processing procedure and the processing among the MS among Fig. 2 in the empty frame C are essentially identical, just have only a user in the dynamic data pond among the MS.Data in the MS dynamic data pond will be through the processing of agent application in RAN after air interface transmission, sends through TCP/IP bunch transport layer, network layer, link layer then.Mostly application program image data in the up link may be the control command of application program, and the generation of application program image data can change with the different of MS disposal ability according to application program.
Fig. 3 realizes air interface schematic diagram of the present invention.Can realize with reference to figure 3 from dynamic data pool to air interface.
As Fig. 3, the data in the dynamic data pond belong to user data area.According to the data volume waiting for transmission of different MS, notify how distributing radio resource of radio resource periodically; The distribution of air traffic channel is also carried out synchronizing cycle, and its cycle is identical with the memory cycle.For third generation wireless communication system, the memory cycle may be got the length 720ms of superframe.
Similarly, for up link, produce instruction or data flow by application program image; Instruction or data flow are stored in the dynamic data pond of MS; The air interface uplink radio resources the same with down link synchronous, distribute periodically; Deliver among the RAN corresponding business access point in the agent application by the air interface radio access layer; Carry out the work of treatment of ICP/IP protocol bunch by agent application among the RAN, used IP address is the IP address of MS; The distribution of the IP address of MS, management, move etc. finished by RAN.
The obviously clear and understanding of those of ordinary skill in the art, the preferred embodiment that the present invention lifted only in order to the explanation the present invention, and not in order to the restriction the present invention, the present invention for the technical characterictic among each embodiment, can combination in any, and do not break away from thought of the present invention.According to the method for dynamic assignment communication channel disclosed by the invention, can have many modes to revise disclosed invention, and except the above-mentioned optimal way that specifically provides, the present invention can also have other many embodiment.Therefore, all genus are conceived the method that can obtain or improvement according to the present invention, all should be included within the interest field of the present invention.
