Abstract
This invention discloses a statistic method for accessed user number in a broadcast multi-cast service, which calculates accessed user number at the beginning of MBMS service, if the statistic number is greater than the preset threshold, then it stops re-calculating the number in the transmission of MBMS service or recalculates the number according to a longer period, otherwise, it calculates the number in terms of the scheduled period, in which, if a preset threshold is greater than the MBMS service, it applies the threshold value of a transmission mode of a point to multipoint in terms of accessed user number.
Description
Technical field
The present invention relates to the broadcast group broadcast technology, particularly in the broadcasting multicast service statistics of number of users and heavily the statistics.
Background technology
Through nearly fast development decades, the crowd that mobile communication is benefited is more and more wider, but the business that it provided is still based on phone and message.Fast development along with internet (Internet), a large amount of mobile multi-media services emerge, the some of them mobile multi-media service requires a plurality of subscriber equipment (UserEquipment, be called for short " UE ") can receive identical data simultaneously, for example video request program, television broadcasting, video conference, online education, interactive game etc., on cable network, can adopt internetworking agreement (Internet Protocol is called for short " IP ") multicast and broadcast technology to realize at present.But because particular network structure, functional entity and wave point etc. that mobile communications network had are all different with the wire communication IP network, and these mobile multi-media services are compared with general data service, have characteristics such as data volume is big, longer duration, delay sensitive, existing IP multicast and broadcast technology can not be directly applied for mobile network.
In order to effectively utilize the mobile network resource, realize the application of mobile multi-media service, third generation partner program (3rd Generation Partnership Project, abbreviation " 3GPP ") multimedia broadcast-multicast service (Multimedia Broadcast/Multicast Service is called for short " MBMS ") has been proposed.Its objective is provides the point-to-multipoint service of a data source to a plurality of users send data in mobile communications network, realize that Internet resources are shared, raising utilization rate of network resource, the interface resource of especially eating dishes without rice or wine.The MBMS business that 3GPP proposes can not only realize the classes of messages multicast and the broadcasting of plain text low rate, and can also realize the multicast and the broadcasting of high-speed multimedia business, and this has complied with the trend of mobile data development undoubtedly.
The MBMS architecture as shown in Figure 1, wherein, broadcast multicast service center (BroadcastMulticast Service Center, be called for short " BM-SC ") be mobile network functional entity in order to support that MBMS is professional and newly-increased, it is the inlet of content supplier, be used for authorizing and initiating the MBMS bearer service, and plan transmits the MBMS content to schedule at mobile network.In addition, in order to support the MBMS business, at UE, universal mobile telecommunications system grounding wireless access network (UMTS TerrestrialRadio Access Network, be called for short " UTRAN "), the enhancing data wireless access network of global system for mobile communications and evolution thereof (GSM EDGE Radio Access Network, be called for short " GERAN "), GPRS serving GPRS support node (Serving GPRS Support Node, be called for short " SGSN "), increased the relevant function of MBMS respectively on the gateway GPRS supporting node (GGSN) functional entitys such as (GPRS Gateway Support Node are called for short " GGSN ").
The MBMS business comprises multicast pattern and broadcast mode, and wherein multicast pattern needs user's corresponding multicast group of contracting, and carries out activation of service, and produces corresponding charge information.Because it is different that multicast pattern and broadcast mode exist, cause also difference of operation flow separately on business demand.
The entire flow that the user receives certain MBMS broadcasting service is at first carried out service statement as shown in Figure 2 in step 210, notify user MBMS the relevant information of business; Afterwards, session begins in step 220, and BM-SC is ready for sending data; In step 230, carry out the MBMS service announcements then, notify user MBMS multicast packet to begin transmission by radio network controller (Radio Network Controller is called for short " RNC "); In step 240, carry out data transmission procedure subsequently; Conversation end in step 250 at last, BM-SC no longer sends data, and then releasing bearing resource.
Because multicast pattern needs user's corresponding multicast group of contract, carry out activation of service, and produce corresponding charge information, so its operation flow is with to broadcast flow process different.As shown in Figure 3, at first in step 310, contract, set up the contact between user and the service supplier; Carry out service statement afterwards in step 320, and carry out user's adding in step 330, promptly the user notification network prepares to receive the MBMS business; Step 340-370 does not subsequently repeat them here corresponding to step 220-250, and last, the user withdraws from step 380, and after withdrawing from, the user has been the member of MBMS multicast group no longer just.
Wherein, data transfer phase in broadcast mode business and multicast pattern business, the MBMS business is transmitted information between UTRAN and UE mode has two kinds of patterns: put multiple spot (Point to Multipoint, be called for short " PTM ") pattern and point-to-point (Point to Point is called for short " PTP ") pattern.Wherein, the PTM pattern is by MBMS point-to-multipoint service channel (MBMS Point-to-Multipoint TrafficChannel, be called for short " MTCH ") send identical data, all add multicast service and can receive the broadcasting service users interest; Ptp mode sends data by Dedicated Traffic Channel (Dedicated TrafficChannel is called for short " DTCH "), has only a corresponding UE can receive these data.
Because in a sub-district, along with the difference of time period, the number of users that receives the MBMS business is also different.In order to save the air interface Radio Resource as far as possible, the MBMS business is used different service bearing modes under different situations.Owing under ptp mode, can use power control, therefore use this bearing mode at number of users more after a little while, can save the transmitted power of base station, reduce the power consumption of base station.But under the situation that number of users increases, use the ptp mode bearer service, expend many Radio Resources, and make base-station transmitting-power bigger, thereby use PTM mode carrying business more for a long time at number of users usually, to save the air interface Radio Resource, reduce the power consumption of base station.
Determine optimum service bearing mode in the professional current slot of each given MBMS, Radio Access Network (Radio Access Network, be called for short " RAN ") must can access the number of users that certain MBMS business demand is arranged in each sub-district, so the MBMS system has introduced counting process and counting process again.
For counting process, be meant when a MBMS service conversation begins, receive the process of the number of users of this MBMS business in the RAN statistics sub-district, determine the service bearer mode of current use by counting process.And counting process again then is to carry out adding up for number of users again in the process in session, confirms by counting process again whether the bearing mode that is using is still suitable bearing mode at present.
Specifically as shown in Figure 4, in step 410, when the MBMS service conversation begins, the enabling counting process, current in the statistics sub-district to the professional interesting number of users of this MBMS, and judge that whether this number is greater than the default limit value m of network.If greater than m, then enter step 420, select PTM mode carrying business, under the PTM pattern, carry out transfer of data, and after the Preset Time section, enter step 440; Otherwise,, select the ptp mode bearer service, and under ptp mode, carry out transfer of data if statistics back number of users then enters step 430 smaller or equal to m.In step 440, start counting process again, again add up current in the sub-district to the professional interesting number of users of this MBMS, and judge that whether this number is still greater than the default limit value m of network, if greater than m, then enter step 450, continue with PTM mode carrying business, and after the Preset Time section, return step 440, start counting process again once more; Otherwise,, switch to the PTP service bearing mode if the number of users of this MBMS business of current use then enters step 460 smaller or equal to m.
In actual applications, there is following problem in such scheme: when professional, may there be the waste of interface-free resources with the PTM mode carrying in the MBMS business.
Cause the main cause of this situation to be, the MBMS service selection after the PTM transmission mode, in the process of carrying out transfer of data, UTRAN need constantly carry out the restatement number, count the result according to restatement and judge whether the PTM pattern of current employing is best transmission mode still, whether needs to switch to the PTP transmission mode.Yet when the UE quantity that receives this MBMS business in certain sub-district is a lot, as for the twice of default limit value even more than the several times, because it is professional or the possibility that shifts out the sub-district is very little that numerous UE do not receive this MBMS simultaneously, to count process just meaningless so carry out restatement this moment.And owing to carrying out to carry out radio resource control layer (RadioResource Controller to the UE under the idle condition when restatement is counted, be called for short " RRC ") connect, to paging channel (Paging Channel, abbreviation " PCH ") UE under the state carries out cell update etc., has wasted many interface-free resources.
Summary of the invention
In view of this, main purpose of the present invention is to provide the statistical method of access customer number in a kind of broadcasting multicast service, makes the MBMS business can reduce unnecessary heavy statistic processes in transmission course.
For achieving the above object, the invention provides the statistical method of access customer number in a kind of broadcasting multicast service, comprise following steps:
Described broadcasting multicast service is added up described access customer number when this business begins, and heavily adds up described access customer number according to first predetermined period in this professional transmission course;
If through described statistics or heavily the statistics access customer number greater than default thresholding, then stop in this business transmission course according to the heavily statistics of described first predetermined period described access customer number.
Wherein, described broadcasting multicast service stops at this business transmission course according to the heavily statistics of described first predetermined period to described access customer number, until this service ending.
In this external described method, also comprise following steps:
If through described statistics or heavily the statistics access customer number greater than default thresholding, then described broadcasting multicast service changes into according to second predetermined period in this business transmission course described access customer number is heavily added up.
In this external described method, described second predetermined period is greater than described first predetermined period.
In this external described method, described broadcasting multicast service adopts the point-to-point bearing mode or puts the transmission of multiple spot bearing mode according to described access customer number.
In this external described method, described default thresholding adopts the threshold value of point to the multiple spot bearing mode greater than described broadcasting multicast service according to described access customer number.
By relatively finding, the main distinction of technical scheme of the present invention and prior art is, statistics access customer number when the professional beginning of MBMS, if this access customer number that obtains by statistics is greater than default thresholding, then stop in the professional transmission of this MBMS heavy statistic processes to access customer number, or the access customer number of this MBMS is heavily added up, otherwise the access customer number of this MBMS business is added up by preset period by time in the longer cycle.Wherein, default thresholding adopts the threshold value of point to multipoint transmission mode greater than the MBMS business according to access customer number.
Difference on this technical scheme brought comparatively significantly beneficial effect, promptly avoids effectively or reduced MBMS business unnecessary heavy statistic processes in transmission course.This promptly for the MBMS business of hot topic, just has very big number of users based on the experience in the operation when this business begins under the normal condition, and number of users generally can not reduce to the stage that must use the PTP bearing mode before this service ending.Because heavily statistics will take a large amount of interface-free resources, so saved interface-free resources by reducing the number of times of heavily adding up.

Embodiment
For making the purpose, technical solutions and advantages of the present invention clearer, the present invention is described in further detail below in conjunction with accompanying drawing.
Core of the present invention is, MBMS adds up its access customer number when this business begins, and in this professional transmission course, heavily add up its access customer number according to first predetermined period, if the access customer number of adding up gained by statistics or heavily is greater than default thresholding, then stop in this business transmission course according to the heavily statistics of first predetermined period access customer number, until this service ending, perhaps stop to change into according to second predetermined period access customer number heavily being added up according to the heavily statistics of first predetermined period to access customer number.
More than principle of the present invention has been carried out simple declaration, the statistical method to access customer number among the first embodiment of the invention MBMS is described in detail below.
As shown in Figure 5, in step 510, when MBMS begins in business, add up its current access customer number.
In step 520, judge by statistics or heavily the access customer number of statistics whether reach the threshold value that adopts the PTM bearing mode, if by statistics or heavily the access customer number of statistics reaches this threshold value, then enter step 530, otherwise, then enter step 540.
In step 530, MBMS selects or maintenance PTM mode carrying business.Specifically, if after first statistics, reach the threshold value that adopts the PTM bearing mode through judging its access customer number, then in this step, MBMS selects PTM mode carrying business; If adopted PTM mode carrying business before, still reach the threshold value that adopts the PTM bearing mode through heavily adding up its access customer number, then in this step, MBMS continues to use PTM mode carrying business.
In step 540, MBMS selects or switches to the ptp mode bearer service.Specifically, if after first statistics, do not reach the threshold value that adopts the PTM bearing mode through judging its access customer number, then in this step, MBMS selects the ptp mode bearer service; If adopted PTM mode carrying business before, but no longer reach the threshold value that adopts the PTM bearing mode through heavily adding up its access customer number, then in this step, the service bearing mode of MBMS is a ptp mode by the PTM mode switch.
In step 550, after the further judgement of MBMS was added up by statistics or heavily, whether this MBMS service access number of users reached default thresholding, and this default thresholding adopts the threshold value of PTM bearing mode greater than MBMS.If, then enter step 570 through judging that its access customer number reaches default thresholding, otherwise, step 560 entered.
In step 560, MBMS heavily adds up its access customer number according to first predetermined period, and after heavily adding up, returns step 520, result after its heavy statistics is compared with the threshold value that adopts the PTM bearing mode, rejudge user after the heavy statistics and insert number and whether reach this threshold value.
In step 570, MBMS does not heavily add up current access customer number.If access customer number is heavily added up in the transmission course before it, then stop heavily statistics, until this service ending to access customer number according to first predetermined period.Avoid MBMS business unnecessary heavy statistic processes in transmission course effectively, saved interface-free resources.
Among the second embodiment of the invention MBMS statistical method of access customer number as shown in Figure 6, step 610-660 does not repeat them here corresponding to step 510-560.
Because the access customer number of this MBMS business reaches default thresholding after adding up by statistics or heavily, therefore in step 670, MBMS heavily adds up access customer number according to second predetermined period, wherein, second predetermined period is greater than first predetermined period, and after heavily adding up according to second predetermined period, returns step 620, result after its heavy statistics is compared with the threshold value that adopts the PTM bearing mode, rejudge user after the heavy statistics and insert number and whether reach this threshold value.
The present embodiment and first execution mode are roughly the same, its difference only is in first execution mode, if add up or heavily add up the access customer number of gained greater than default thresholding through MBMS, then access customer number is not heavily added up, until this service ending, and in the present embodiment, if add up or heavily add up the access customer number of gained greater than default thresholding through MBMS, then access customer number is heavily added up, and this second predetermined period is greater than first predetermined period originally according to second predetermined period.Present embodiment is by heavily adding up access customer number with the long cycle, reduce MBMS business unnecessary heavy statistic processes in transmission course as much as possible, when saving interface-free resources, compatible mutually with prior art better, make MBMS insert number when adopting the threshold value of PTM bearing mode, still can in time switch to the PTP service bearing mode the user.
Though pass through with reference to some of the preferred embodiment of the invention, the present invention is illustrated and describes, but those of ordinary skill in the art should be understood that and can do various changes to it in the form and details, and without departing from the spirit and scope of the present invention.
