Description
Technical field
The present invention relates to multi-carrier EV-DO (Evolution-Data Only) technical field, more particularly, the present invention relates to a kind of multi-carrier EV-DO system reverse traffic channel control information implementation method.
Background technology
Along with the fast development of Internet protocol (IP) data network, support high speed packet data service in order to go up at code division multiple access (CDMA), the notion of EV-DO has been proposed at present.
In November, 2000,3G (Third Generation) Moblie collaborative project tissue (3GPP) 2 promulgation 1xEV-DO versions 0 standard.1xEV-DO version 0 uses time-division multiplex technology on the forward link, and adopts adaptive modulation and coding mode, dynamic channel assessment, and mixed automatic repeat request (ARQ) waits machine-processedly, and the forward direction peak rate is brought up to 2.4Mbps.In April, 2004, the issue of 1xEV-DO version A standard, 1xEV-DO version A is the enhancement mode of 1xEV-DO version 0, it is by a series of technological means, physical layer at reverse link has adopted ARQ technology and enhancement mode MAC algorithm, improving delay character, thereby make forward direction and reversed peak speed bring up to 3.1Mbps and 1.8Mbps respectively.
The 1XEV-DO system belongs to single-carrier system, and one of them wireless access terminal (AT) can support a plurality of data flow transmission simultaneously.Reverse rate control in the 1XEV-DO system is by reverse traffic channel MAC control protocol, each data flow is carried out resource allocation, to determine the transmission rate of this reverse carrier wave.For the resource allocation of each stream, each stream all has a bucket that distributable resource is accumulated.In the time of each scheduling, according to the stock number that enters bucket and the available volume of resources of accumulation, draw the stock number that the possibility maximum goes out bucket, take all factors into consideration the situation of each stream again, determine a kind of speed grade to satisfy maximum and go out a barrel resource quantitative limitation.The packet that final decision sends is made of jointly selected stream, and each stream is contributed a given data for this packet.In data transmission procedure, the parameter of bucket all is the AT real-time update, and the parameter of bucket also can be specified by access network (AN).
In the reverse traffic channel transmission, every certain time interval, AT just can pass through Request message, the quantity (NumMACFLows) of notice Radio Access Network (AN) the current stream that is transmitting, for supplying the maximum (MaxSupportableTxT2P) of Resources allocation on length of data queue of each flow distribution (QueueLength) and the single carrier wave.At any time simultaneously, AN can pass through Grant message, the parameter that notice AT uses this Grant message to carry for each appointed stream is carried out correlation computations, and wherein the Grant message parameter of carrying comprises in traffic identifier (MACFlowID), this inflows bucket stock number (T2Pinflow), this stream bucket and accumulates stock number (BucketLevel), appointment maintenance duration (TT2Phold).
By Request message, AN can understand the current transmission situation of AT; By Grant message, AN can control the transmission of each stream.Request message and Grant message are very important control messages in the 1xEV-DO system reverse Traffic Channel MAC agreement.
Entrained parameter is all only at the single carrier wave of current use in existing Request message and the Grant message, and in multicarrier system, AT may transmit on many reverse carrier waves simultaneously, if therefore AT still transmits information by existing Request message to AN in multicarrier system, AN just can not distinguish it is the transmission information of the reverse carrier wave of which bar; Equally, if AN still carries out the Control Parameter renewal by existing Grant message to AT in multicarrier system, AT then can not distinguish Control Parameter on which bar carrier wave is upgraded.
Therefore, Request message of the prior art and Grant message are only applicable to single-carrier system, and can't realize the information interaction between the AT and AN in the multicarrier system, thereby can not guarantee the transfer of data of reverse traffic channel in the multi-carrier EV-DO system.

Step 202:AT receives assembling back Grant message, and according to the identification information of every carrier wave, obtains the Control Parameter with corresponding every the carrier wave of identification information.
Here, AN receives after the Grant message of assembling back, resolve assembling back Grant message, obtain the Control Parameter of identification information and every carrier wave of every carrier wave, and identification information according to every carrier wave, obtain Control Parameter with corresponding every the carrier wave of identification information, and generally include the Control Parameter of each bar stream in this carrier wave in the Control Parameter of every carrier wave, upgrade so AN can carry out Control Parameter to the current a plurality of data flow of AT, a plurality of carrier wave, thereby can control the reverse traffic transmission of AT.
In the above process, AN can send assembling back Grant message to AT in any time of reverse traffic transmission.AN can respond the Request message of AT transmission and send assembling back Grant message, also can initiatively send to AT and assemble back Grant message, and AN can send assembling back Grant message to AT at any time.
The method flow of AN to AT circular carrier Control parameter more than described.Yet, in some cases, AN to AT send Grant message with circular carrier Control parameter and and then the reverse traffic transmission of control AT, be based on Request message that AT sends to AN.Below this process is described.
Fig. 3 is according in the transmission of the multi-carrier EV-DO system reverse traffic channel of the embodiment of the invention, the exchange method schematic flow sheet of AN and AT.As shown in Figure 3, this method may further comprise the steps:
Step 301:AT assembling Request message, assembling back Request message comprises the transmission information of identification information and every carrier wave of every carrier wave, wherein the identification information of every carrier wave is corresponding with the transmission information of this carrier wave, and AT sends assembling back Request message to AN;
Step 302:AN receives assembling back Request message, and according to the identification information of every carrier wave, obtains the transmission information with corresponding every the carrier wave of identification information;
Step 303: in response to the transmission information of every the carrier wave that obtains, AN assembling Grant message, and, wherein comprise the Control Parameter of each each data flow of carrier wave in the Grant message of assembling back to AT transmission assembling back Grant message;
Step 304:AT receives assembling back Grant message, obtains the Control Parameter of each each data flow of carrier wave, and upgrades the Control Parameter of each each data flow of carrier wave of this AT self.
In the above process, can preferably preestablish the time interval, in step 301, every this time interval, AT periodically sends assembling back Request message to AN.The Control Parameter of every the carrier wave that carries in the Grant message comprises traffic identifier in this carrier wave, flows into a bucket stock number, accumulation stock number and specify and keep duration in the stream bucket, AT is after obtaining Grant message so, further keep duration, each data flow in every carrier wave is carried out the resource allocation control and treatment according to accumulation stock number and appointment in traffic identifier, an inflow bucket stock number, the stream bucket.
The above is preferred embodiment of the present invention only, is not to be used to limit protection scope of the present invention.Within the spirit and principles in the present invention all, any modification of being done, be equal to replacement, improvement etc., all should be included within protection scope of the present invention.
