Description
Technical field
The present invention relates to the counting technology in the evolution type multimedia broadcast multicast service (E-MBMS), relate in particular to a kind of E-MBMS method of counting, system and equipment.
Background technology
Multimedia broadcast multi-broadcasting business (MBMS) is a kind of business newly-increased in third generation partner program (3GPP) the R6 standard, the purpose of MBMS business be with a kind of mode very efficient, economic, that share be the multiple terminals provide can be from any to multiple spot unidirectional multi-medium data that passes down.As one of the most attractive business model in the next generation mobile communication field, the MBMS business is subjected to the great attention of operator and equipment vendors.
In 3GPP Long Term Evolution (LTE) system, the MBMS system has also been proposed the evolution demand, that is: the multi-media broadcasting service of higher rate is provided, at this moment, this MBMS system is called the E-MBMS system.In the E-MBMS system design process, in order to improve the performance of system, system needs the terminal feedback-related information under specific circumstances, as counting process, NACK and CQI feedback etc.
In RAN2#58 meeting, the situation of terminal in the professional receiving course of E-MBMS has been discussed, and agreement E-MBMS business should be supported many sub-districts MBSFN pattern, also to support single sub-district PTM mode, and the base station e-NodeB of evolution needs the definite terminal number that receives E-MBMS in the e-NodeB overlay area of knowing from many sub-districts MBSFN mode switch to single sub-district PTM mode the time.
In Chinese patent application number be: 200710065166.1, patent name is to disclose in the patent application of " method of feedback information and device in the mbms service ": for the less sub-district of radius of society, when for example radius of society is less than 5km, e-NodeB adopts specific m sequence to carry out the professional application of E-MBMS, the m sequence is a pseudo random sequence, (Preamble) can regard white noise as with respect to random access leader sequence, and m sequence of interpolation is very little to the detection influence of whole Preamble in each sub-district; For medium sub-district (radius of society is 30km) and the bigger sub-district of radius of society, for example radius of society is 100km, use Preamble to carry out the professional application of E-MBMS, for example: in UMTS Terrestrial radio access network network (EUTRAN) time division duplex (TDD) system of evolution, a part that adopts the TS1 time slot is as Random Access Channel (RACH), the length of TS1 is 0.675ms, can hold based on 10 of OFDM (DFT-S OFDM) symbols of Fourier transform expansion, consideration is for the protection of time uncertainty, vacate two DFT-S OFDM symbols at interval as protection, so, the length of operable Preamble is 719, if do not carry out cyclic shift, there are 718 sequences to use; If carry out cyclic shift, under different radius of society situations, at least still there are 718 sequences to use; The TDD system design is 16 Preamble in each sub-district, 32 sub-districts, therefore, needs 512 Preamble at least; In this case, in each sub-district, can use a special Preamble to carry out the professional application of E-MBMS.
Wherein, the concrete counting process that is provided in this patent application may further comprise the steps:
Step 101:e-NodeB is the one or more Preamble of E-MBMS counting process specific assigned, and notifies all terminals by the system information on the Broadcast Control Channel (BCCH).
Like this, can not receive described announcement information even do not receive the terminal of point-to-multipoint control channel (MCCH), any terminal can not use this Preamble as other purposes yet.
Whether step 102:e-NodeB decision is at the professional counting process of initiating of certain E-MBMS, if counting process is initiated in decision, then on E-MBMS MCCH channel, send counting request (CountingRequest) signaling, and startup timing device, in setting-up time, wait for the counting response of terminal feedback, that is: wait for the corresponding Preamble that terminal sends.
Wherein, if in step 101, e-NodeB is a plurality of Preamble of E-MBMS counting process specific assigned, so, and the Preamble of required use in the time of in described counting demand signalling, need comprising the counting response that carries out this E-MBMS business.
Step 103: after terminal receives the counting demand signalling, judge according to the E-MBMS service identification whether this business is self interested business, if terminal wishes to receive the Preamble that just goes up appointment in forwarding step 101 or the step 102 in Random Access Channel (RACH) subsequently, carry out counting response.
Step 104: in the setting-up time of the described timing device of step 102,, then can determine to have in the sub-district terminal to wish to receive this E-MBMS business, execution in step 105 if e-NodeB receives described counting sequence; If do not receive described counting sequence, then e-NodeB thinks does not have terminal to wish to receive corresponding E-MBMS business in this sub-district, finishes current flow process.
Wherein and since be hopeful to receive this E-MBMS business terminal all use identical counting sequence to respond, what terminals e-NodeB can not define is wished to receive described business.
Step 105:e-NodeB sends counting the finish command on MCCH, the notice terminal stops the counting response process to this E-MBMS business.
Step 106:e-NodeB judges whether to exist other E-MBMS service needed to initiate counting process, if having then execution in step 102, if do not have, then current handling process finishes.
By above description as can be seen, since be hopeful to receive corresponding E-MBMS business terminal will use identical Preamble to carry out counting response simultaneously, therefore, the base station can only determine whether this business has terminal to wish to receive, and can not determine specifically have what terminals to wish to receive.Under the above-mentioned situation,, still, determine but also inapplicable to the E-MBMS business of single sub-district PTM mode from many sub-districts MBSFN mode switch for need for the professional did not influence of E-MBMS that only adopts the PTM bearing mode transmission of single sub-district.

Embodiment
Basic thought of the present invention is: when the e-NodeB decision is initiated counting process to E-MBMS is professional, send counting demand signalling and corresponding probability factor to each terminal; After terminal received described counting demand signalling and probability factor, when determining self to send corresponding counting sequence, the relative position according to the descending time slot of self correspondence sent corresponding counting sequence; The described counting sequence that e-NodeB sends the terminal that receives detects, and counts the peak value number above power threshold.
Below, be described with reference to the accompanying drawings the realization of E-MBMS method of counting of the present invention, system and equipment by specific embodiment.
Fig. 2 is an E-MBMS method of counting schematic flow sheet of the present invention, and as shown in Figure 2, this method comprises:
Step 201:e-NodeB is the one or more counting sequences of E-MBMS counting process specific assigned, and the resource of the required use of counting process, and notifies all terminals by the system information on the BCCH channel.
Like this, can not receive described signaling, and any terminal can not use this counting sequence and corresponding resource as other purposes even do not receive the terminal of MCCH channel yet.
Wherein, described counting sequence can have multiple situation, for example: can be Preamble, or other random sequences, as m sequence, pseudo random sequence etc., still, when using other random sequences, described other random sequences need be carried out the detection of correlation with original Preamble, check whether its correlation is relatively good; Perhaps, also can be as introducing in the background technology, when radius of society hour, use the m sequence, and, then use Preamble when radius of society greatly the time.Wherein, rich as Preamble when using Preamble, then can give a plurality of Preamble of same traffic assignments to improve the accuracy of counting.
Wherein, how e-NodeB realizes that specifically the distribution of counting sequence and resource belongs to known technology, repeats no more here.
Wherein, for being the counting process Resources allocation, also can in step 202, after the e-NodeB decision is at the professional initiation of certain E-MBMS counting process, carrying out, and in described counting demand signalling, comprise described resource allocation result to notify each terminal.In addition, also can use two kinds of methods for described Resources allocation: a kind of method is and the RACH shared resource that is: to use RACH to count; Second method is to distribute independent private resource to carry out counting operation, and this method can guarantee the accuracy counted, and can avoid and the interference that inserts at random.
Whether step 202:e-NodeB decision is at the professional counting process of initiating of certain E-MBMS, when if counting process is initiated in decision, on MCCH, send a counting demand signalling and corresponding probability factor, and startup timing device, on corresponding physical resource, whether sense terminals returns corresponding Preamble in setting-up time.
Wherein, the reason that e-NodeB sets probability factor is: when terminal number is too much, in step 205, the peak value difficulty that e-NodeB distinguishes counting sequence will increase, and also there is certain difficulty in the detection of single peak value, therefore, set the probability factor of a counting, that is to say that not every terminal is all carried out counting response, but a certain proportion of terminal is carried out counting response, like this, just reduced the number of the terminal of counting response, so, the accuracy of e-NodeB detection peak number will improve accordingly.
Certainly, according to practical situations, also exist and can not set probability factor, promptly probability factor is 1 possibility.At this moment, method of counting of the present invention is carried out step 206 and is promptly finished, and in step 205, need not to judge whether counting sequence conflicts, and directly adds up described peak value number.In step 206, if described peak value number during less than described counting threshold value, directly change single sub-district PTM mode over to, and the step 206 of this moment is an optional step.
Wherein, if in step 201, e-NodeB is a plurality of Preamble of E-MBMS counting process specific assigned, will comprise the Preamble of required use when carrying out this professional counting response so in the counting demand signalling.Wherein,, can set the value of this probability factor in advance, for example, can so that in step 207, reduce the possibility of counting sequence conflict, and only need increase the operation of probability factor for greater than 0 less than a smaller value of 1 for probability factor; Perhaps also can rule of thumb be worth and set described probability factor, so that reduce the running time of the whole flow process that increases owing to continuous adjustment probability factor.
Wherein, how e-NodeB specifically determines whether to initiate counting process, and initiates how to send described counting demand signalling after the counting process and belong to known technology, repeats no more here.
Step 203: after terminal receives described counting demand signalling and corresponding probability factor, according to E-MBMS service identification and probability factor etc., determine whether self carries out counting response, that is: determine whether to send corresponding counting sequence, if send, then execution in step 204, otherwise, terminal is not carried out any operation, and the current flow process of this terminal correspondence finishes.
Wherein, how terminal judges that specifically self whether carrying out counting response can use existing correlation technique, repeats no more here.
Step 204: terminal sends corresponding counting sequence according to the relative position of the descending time slot of self correspondence.
Wherein, after terminal needs to carry out synchronously with e-NodeB earlier in the prior art, just send corresponding counting sequence, so, all are all identical with the position of the counting sequence that the synchronous terminal of e-NodeB sends, this will cause in the step 205, and e-NodeB can't distinguish a plurality of peak values, makes the accuracy of counting reduce.
And in this step, terminal is carried out counting response and when sending corresponding counting sequence, can not use lead transmission lock in time, but according to the relative position of self pairing descending time slot, send counting sequence, thereby the counting sequence that all terminals are sent arrives the time randomization of e-NodeB, as shown in Figure 3.From the situation that terminal distributes the sub-district, the counting sequence that each terminal sends arrives the peak of e-NodeB and roughly obeys even distribution, and like this, each peak value just can be distinguished preferably in the base station, obtains count results more accurately.
Wherein, terminal also can be carried out randomization with self pairing transmitting time, for example multiply by a certain random function, so that sending the time of described counting sequence, terminal has more randomness, accordingly, e-NodeB time of receiving the described counting sequence that each terminal sends also has randomness.
Here, the concrete transmission of described counting sequence and the randomization how terminal carries out transmitting time of how realizing all can be used existing correlation technique, repeats no more here.
Step 205:e-NodeB utilizes coherent detection, detects the correlated count sequence, and judges whether there is conflict between counting sequence, if exist, then execution in step 208, and if there is no, then statistics surpasses the peak value number of power threshold, and execution in step 206 afterwards.
Wherein, e-NodeB detects the peak value that surpasses power threshold and can use existing correlation technique specifically how by coherent detection, repeats no more here.
Step 206: according to the power threshold of setting, the peak value number that e-NodeB relatively surpasses power threshold and the E-MBMS of setting count the magnitude relationship of threshold value, if when being not less than described counting threshold value, then change many sub-districts MBSFN pattern over to, current handling process finishes; If during less than described counting threshold value, execution in step 207.
Step 207: judge whether probability factor is 1, if be not 1, then execution in step 208; If be 1, then adopt single sub-district PTM mode to carry out the transmission of E-MBMS business datum, counting process finishes.
Step 208:e-NodeB adjusts probability factor, and afterwards, execution in step 202 resends the counting demand signalling, beginning counting process, that is, and circulation execution in step 202 to 208.
Described adjustment probability factor comprises three kinds of situations: when clashing between the counting sequence that receives, promptly directly during execution in step 207, will reduce probability factor from step 205; When peak value number during, improve probability factor less than described counting threshold value.In addition, when carrying out the adjustment operation of probability factor, need to guarantee that adjusted probability factor is greater than zero, smaller or equal to 1.
Wherein,, can use and set a certain step value, increase or reduce the value of probability factor in each cyclic process according to actual conditions, perhaps, also can set according to actual conditions for adjusting described probability factor.Because in actual applications, the method for the described probability factor of employed adjustment also can appropriate change, and how to realize that specifically the adjustment of above-mentioned probability factor can use prior art, repeats no more here.

Counting determination module 420 is used for according to the described information that receives, determine self under terminal whether send corresponding counting sequence, when determining to send described counting sequence, counting sequence and corresponding resource information are sent to data transmission blocks 430.Wherein, described resource information can be included in the described system information, also can be included in the described counting demand signalling, it depends on that e-NodeB specifically will be added in the described system information for the resource information of counting process institute Resources allocation, still is added in the described counting demand signalling.
