Abstract
The present invention discloses a method for checking the consistency of data transmission quantities between an uplink and a downlink in a mobile communication system. According to time between information reception and information sending and the speed rate of each business, effective ranges of counter values corresponding to the wireless bearing of each business are separately estimated, and a network side or a user side is used for judging whether the received counter values lie in the calculated effective ranges. If the received counter values lie in the calculated effective ranges, consistency requirements are met; otherwise, corresponding wireless resources are released to control connection. The method can be used for avoiding unnecessary RRC connection release and improving the reliability and the accuracy of the consistency test of the data quantities between the uplink and the downlink.
Description
Technical field
The present invention relates to data in mobile communication system transmission quantity detection technique, be meant especially and check the conforming method of up-downgoing volume of transmitted data in a kind of broadband CDMA system.
Background technology
Along with the development of 3G (Third Generation) Moblie technology, various emerging mobile communication system and corresponding standard are arisen at the historic moment.As the 3G (Third Generation) Moblie standard, Wideband Code Division Multiple Access (WCDMA) (WCDMA, Wideband CodeDivision Multiple Access) technology is exactly one of them, accordingly, the WCDMA mobile communication system is by core net (CN, Core Net), universal mobile telecommunications system grounding wireless access network (UTRAN, UMTSTerrestrial Radio Access Network) and subscriber equipment (UE, User Equipment) are formed.Wherein, the interface definition between CN and the UTRAN is the Iu interface, and the interface definition between UTRAN and the UE is the Uu interface.
Each UE will communicate with UTRAN, at first to set up a Radio Resource control (RRC with UTRAN, Radio Resource Controller) connects, be used between UE and UTRAN, controlling the mutual of signaling, and realize the transmission of business datum by professional radio bearer (RB, Radio Bearer).According to the requirement of security of system, invaded by invalid message for preventing the business datum that sends between UTRAN and the UE, just need be provided with one check certain RRC connect in the whether consistent mechanism of the up-downgoing data volume that sends of UE and the professional RB of UTRAN.
At third generation partner program (3GPP, 3rd Generation Partnership Project) in the agreement, the up-downgoing data volume consistency check mechanism that adopts is at present: check flow process (Counter check procedure) by simple counter, finish the conforming inspection of up-downgoing data volume to UE and UTRAN transmission.The realization principle of this up-downgoing data volume consistency check mechanism is:
Each Radio Link control (RLC, Radio Link Controller) adoptable data-transmission mode has: affirmation mode (AM, Acknowledged Mode) or Unacknowledged Mode (UM, UnacknowledgedMode), wherein the AM pattern comprises data re-transmission mechanism.No matter adopt which kind of pattern, each uses the uplink and downlink transfer of data of the professional RB of RLCAM or UM pattern all to distinguish a corresponding encryption counter (COUNT-C), the length of each COUNT-C value is 32 bits, form by Hyper Frame Number (HFN, Hyper FrameNumber) and RLC sequence number, wherein, the RLC sequence number increases progressively and increases progressively with volume of transmitted data, the RLC sequence number whenever increases progressively one-period HFN and adds 1, and therefore, the COUNT-C value increases progressively with volume of transmitted data.
All used the COUNT-C value of the professional RB correspondence of RLC AM or UM pattern during RRC of UTRAN monitoring connected, stipulate according to existing protocol, the threshold value and the granularity of flow process checked in the initiation that UTRAN is provided with according to network side, after certain COUNT-C value reached the thresholding that sets, UTRAN initiated counter and checks flow process.Such as, be provided with and initiate to check that the threshold value of flow process is 200, when upstream or downstream COUNT-C value reached 200 between UE and the UTRAN, UTRAN will initiate once to check flow process.The realization of particular exam flow process is as shown in Figure 1:
Step 101:UTRAN transmitting counter checks that message COUNTER CHECK gives UE, wherein comprises the highest significant position (MSB) that all use the COUNT-C value of UM and AM RLC radio bearer.
After step 102～103:UE receives COUNTER CHECK message, the MSB of the corresponding COUNT-C value that the MSB of each COUNT-C value of carrying in this message is preserved with this locality respectively compares, judge whether unanimity, and transmitting counter checks that response message COUNTER CHECK RESPONSE gives UTRAN, if check consistent, then do not carry corresponding local COUNT-C information of preserving among the COUNTER CHECK RESPONSE, otherwise, carry the MSB of corresponding local COUNT-C value of preserving in the COUNTER CHECK RESPONSE message.
Here, why relatively the MSB of COUNT-C value in fact also is to consider that COUNT-C error may occur when transmission, so reserve certain amount of redundancy.According to the existing protocol regulation, the bit number of MSB is high 20 bits of COUNT-C value.
After step 104:UTRAN receives response message, judge whether comprise COUNT-C information in the message,, then finish this and check flow process if do not comprise any COUNT-C information; Otherwise, can discharge RRC and connect.
There are following 2 problems in above-mentioned solution:
One) because in above-mentioned counter checking process, professional RB does not stop transfer of data, so, it is inconsistent just to exist following two kinds of situations can cause sending and receive the MSB of both sides COUNT-C value: first kind of situation, data are lost in process of transmitting, and the MSB of recipient COUNT-C value is less than the MSB of transmit leg COUNT-C value; Second kind of situation, traffic data rate is higher, when UE receives COUNTERCHECK message, initiates the counter inspection with UTRAN and compares constantly, and the MSB of COUNT-C value increases progressively.So, connect release with regard to unnecessary RRC occurring owing to the COUNT-C value is inconsistent.Especially for high speed business, as the data service of 384Kbps, the speed that the COUNT-C value increases progressively is faster, the easier generation of above-mentioned situation.
When two) prior art only points out that UTRAN finds to contain COUNT-C information in the response message, can discharge RRC and connect, which should not carry out suitably handle, could guarantee the mistake dismounting of minimizing link but clearly provide UTRAN.
Summary of the invention
In view of this, main purpose of the present invention is to provide checks the conforming method of up-downgoing volume of transmitted data in a kind of mobile communication system, makes it can avoid unnecessary RRC to connect and discharges, and improves the reliability and the accuracy of up-downgoing data volume consistency detection.

Embodiment
The present invention is further described in more detail below in conjunction with drawings and the specific embodiments.
According to the analysis of prior art is found that the main cause that causes the counter inspection error to occur is: during the MSB of UE comparing cell side and self COUNT-C value, do not consider rational, acceptable excursion of COUNT-C value.Therefore, the present invention is according to the transmission rate of each professional RB and network side such as the request of sending of UTRAN side and receive duration between the response, calculate rational excursion of COUNT-C value, and then judge whether the COUNT-C value of being received is in the COUNT-C value effective range that is calculated, if the COUNT-C value is legal; Otherwise the COUNT-C value is illegal, discharges corresponding RRC and connects.
For solving the problems of the technologies described above, be example still with the WCDMA system, whether consistent up-downgoing volume of transmitted data inspection method in the mobile communication system provided by the present invention as shown in Figure 2, may further comprise the steps:
Step 201: when UTRAN monitored when certain COUNT-C value arrives the threshold value that sets in advance, UTRAN initiates to check flow process.Be exactly specifically: the UTRAN transmitting counter checks that message COUNTERCHECK gives corresponding UE, and the delivery time of recording counter inspection message, counter checks that comprising all in the message uses UM and the COUNT-C value of AM RLC radio bearer or MSB of COUNT-C value.That is to say, the UTRAN transmitting counter checks that message gives the COUNT-C institute that surpasses threshold value corresponding UE under professional, comprises this UE current all use RLC AM and/or the pairing COUNT-C value of professional RB of UM pattern or MSB of COUNT-C value in this message.
After step 202～204:UE receives COUNTER CHECK message, the MSB of the corresponding COUNT-C value that the MSB of each COUNT-C value of carrying in this message is preserved with this locality respectively compares, judge whether unanimity, and transmitting counter checks that response message COUNTER CHECK RESPONSE gives UTRAN, if check consistent, then do not carry corresponding local COUNT-C information of preserving in the COUNTER CHECK RESPONSE message, otherwise, carry corresponding local COUNT-C value of preserving in the COUNTER CHECK RESPONSE message.
After step 205:UTRAN receives response message, judge whether comprise COUNT-C information in the message,, then finish this and check flow process if do not comprise any COUNT-C information; Otherwise, to each the COUNT-C value that comprises in the response message, execution in step 206～208.
Step 206:UTRAN checks message delivery time and the duration between the current UE of the receiving response moment according to the counter that is write down, and the speed of the pairing professional RB of current C OUNT-C value, calculate self from sending the maximum amount of data N that checks that message can receive or send in the period of receiving response, as the maximum variable quantity of COUNT-C value; And, obtain the upper limit MSB of corresponding COUNT-C value MSB effective range according to the corresponding COUNT-C value of self current storage and the maximum amount of data N that calculates
1With lower limit MSB
2MSB
1And MSB
2Obtain according to formula (1) and formula (2) respectively:
MSB
1=MSB
i(COUNT-C value-N) (1)
MSB
2=MSB
i(COUNT-C value+N) (2)
In the above-mentioned formula, N is a constant, and its value is the maximum amount of data that calculates; MSB
iHighest significant position i bit is got in expression, and the value of i can be set as required, and the size representative of i value is to the size of error degrees of tolerance, and i gets 20 usually; The COUNT-C value is the initiation counter inspection COUNT-C value constantly of UTRAN self storage.
Said process is improved on the basis of existing standard agreement, changes minimum.In fact, in concrete application, also can be only in UTRAN, utilize the method for determining effective range each COUNT-C value is judged and to be checked.Such as: UTRAN initiates counter and checks flow process, checks message COUNTER CHECK to the UE transmitting counter; After UE receives COUNTER CHECK message, directly return the COUNT-C value of all RLC radio bearers that carry self storage or the counter inspection response message COUNTER CHECK RESPONSE of COUNT-C value MSB to UTRAN; After UTRAN receives response message, continue to carry out checked operation according to step 205～208.Owing to be the legitimacy of judging the COUNT-C value according to effective range,, guarantee reliability, accuracy that the COUNT-C value detects simultaneously so the mistake that this scheme can avoid RRC to connect is removed.
In practical operation, can also calculate COUNT-C value effective range, and whether legal consistency check mode applies to directly among the UE according to effective range judgement COUNT-C value, specific practice as shown in Figure 3:
Step 301: when UTRAN monitored when certain COUNT-C value arrives the threshold value that sets in advance, UTRAN initiates to check flow process: the UTRAN transmitting counter checks that message COUNTER CHECK gives UE, comprises all and uses UM and/or the COUNT-C value of AM RLC radio bearer or the MSB of COUNT-C value in this message; After UE receives COUNTER CHECK message, to each COUNT-C value execution in step 302 of carrying in this message to step 307.
Step 302:UE is according to receiving that the COUNTER CHECK message moment and the UTRAN that estimates send the duration of this message between the moment, and the speed of the pairing professional RB of current C OUNT-C value, calculate self from receiving the maximum amount of data N that checks that message can receive or send to the period of sending response, as the maximum variable quantity of COUNT-C value, and then obtain the upper limit MSB of corresponding COUNT-C value MSB effective range

2Equally, MSB
1And MSB
2Obtain according to formula (1) and formula (2) respectively.Here, the moment that described estimation UTRAN sends this message can obtain by the propagation delay time of estimating down-ward link, can adopt existing time delay algorithm for estimating to obtain propagation delay time, and then estimates the moment that UTRAN sends counter inspection message according to propagation delay time.
Whether the MSB that step 303～305:UE is judged the corresponding COUNT-C value of carrying in the message of receiving is at the MSB of correspondence
1And MSB
2Between, that is: check that whether the MSB of the corresponding COUNT-C value of carrying in the message is at effective range [MSB
1, MSB
2] in, if, then counter inspection success, UE returns counter to UTRAN and checks response message COUNTER CHECK RESPONSE, does not carry corresponding C OUNT-C information in this message; Otherwise, carry corresponding local COUNT-C value of preserving in the COUNTER CHECK RESPONSE message.
After step 306～307:UTRAN receives response message, judge whether comprise COUNT-C information in the message,, then finish this and check flow process if do not comprise any COUNT-C information; Otherwise directly discharging not, the corresponding RRC of the COUNT-C value in effective range connects.
In the above-mentioned steps, owing to be the legitimacy of judging the COUNT-C value by the effective range of COUNT-C value, thereby the mistake that can avoid RRC to connect discharges, and guarantees reliability, accuracy that the COUNT-C value detects simultaneously.
The present invention can also check whether the COUNT-C value is legal simultaneously in the determination methods of UE side and UTRAN side employing COUNT-C value effective range.So, can make the more remarkable effect of up-downgoing data volume consistency check, more accurately and reliably.
In above-mentioned all schemes, the network entity of carrying out all operations among the UTRAN can be base station, radio network controller (RNC) etc.
The above is preferred embodiment of the present invention only, is not to be used for limiting protection scope of the present invention.
