Multicast broadcasting service user amount statistical method and terminal

The application is that application number is CN200610131980.4, and the applying date is on October 13rd, 2006, and subject matter is China's dividing an application in first to file of " multicast broadcasting service user amount statistical method and base station ".

Technical field

The present invention relates to wireless communication field, particularly the multicast and broadcast technology in the WiMAX system.

Background technology

Along with the growth of development of Communication Technique and user's request, data service has obtained developing rapidly, and the increasing rapidly of data business volume makes people grow to even greater heights to the demand of communication bandwidth, and broadband access shows a huge market to industrial circle.For breaking through the bandwidth bottleneck of Access Network, people have released multiple broadband access technology.

IEEE802.16 is (the Institute of Electrical andElectronics Engineers of Institute of Electrical and Electronics Engineers, be called for short " IEEE ") in promulgation in December calendar year 2001, the standard that provides last kilometer WiMAX to insert at metropolitan area network is provided.The IEEE802.16 standard mainly comprises 802.16a, 802.16RevD and three standards of 802.16e.

Micro-wave access to global intercommunication (Worldwide Interoperability for Microwave Access, be called for short " WiMAX ") be that present industry is to the wireless MAN access technology based on IEEE 802.16 series standards, its elementary object provides a kind of under some multivendor environment to multiple spot of metropolitan area network, effectively the broadband wireless access means of interoperability.

Specifically, 802.16 series standards have been stipulated the air interface part protocol layer of WiMAX system, mainly comprise physical layer (PHY), and medium access control (Medium Access Control is called for short " MAC ") layer.Wherein, the PHY layer is finished physically to operations such as the modulation of signal and encoding and decoding, and the MAC layer is mainly finished the medium access control function of WiMAX system.

Fig. 1 illustrates the end-to-end reference model of WiMAX.Wherein the R1 interface is a wireless air interface, is mainly defined by IEEE802.16d/e.All the other interfaces are wireline interface.

As can be seen, WiMAX mainly comprises travelling carriage (Mobile Station, be called for short " MS ")/subscriber station (Subscribe Station, abbreviation " SS "), access service network (Access ServiceNetwork, be called for short " ASN ") and connectivity serving network (Connectivity Service Network is called for short " CSN ").

Wherein, ASN is defined as the network function set that the wireless access service is provided for the WiMAX user terminal, and ASN has comprised BS and ASN gateway (ASN GateWay is called for short " ASN-GW ") network element, and an ASN may be shared by a plurality of CSN.

The major function of ASN comprises the function of BS and the function of ASN-GW.Wherein, the function of BS has: provide that BS is connected with the L2 of subscriber station SS/MS, the compression and the encryption of RRM, measurement and the power control and the data of eating dishes without rice or wine.The function of ASN-GW has: for SS/MS authentication function provides agency (proxy) function; Support the network of NSP to find and selection; For SS provides relaying (Relay) function of L3 information, as IP address assignment, RRM.

In addition, can also comprise in (non-essential function): the ASN and switching; SS paging and location management are as paging controller (Paging Controller is called for short " PC ") functional entity; Tunnel management between the ASN-CSN is equivalent to the external agent (FA) in the mobile IP technology; The vision location registration, anchor SFA functional entity.

CSN is defined as to the WiMAX user terminal IP is provided Connection Service.CSN mainly provides the IP address assignment of following function: SS/MS, Internet inserts, checking, authorize, charging protocol (Authentication, Authorization, Account, be called for short " AAA ") agency (proxy) or service (server), authorization control based on the user, ASN is to the tunnel of CSN, WiMAX user's charging and the clearing between the operator, tunnel under the roaming condition between the CSN, switching between the ASN and various WiMAX service are (as location-based business, multi-medium multi-packet broadcasting and broadcasting service, the IP Multimedia System business).

MS/SS is (moving) terminal, and the user uses this terminal to insert the WiMAX network.

More than WiMAX and network architecture thereof are illustrated, below to Multimedia Broadcast Multicast Service (Multicast; Broadcast Service is called for short " MBS ") simply introduce.

The usually said communication of people is the communication between a node and another one node, but increase along with user's request, and the introducing of multiple medium, the user need carry out the communication of one-to-many or multi-to-multi, put the multiple spot transmission mode of (Point to Multipoint is called for short " PTM ") thereby produced.In order to support these patterns to realize the one-to-many multicast broadcasting service on mobile network, simultaneously in order to effectively utilize mobile network resource, prior art has defined the MBS business on the basis of WiMAX.The MBS business is that the point-to-multipoint service of a data source to a plurality of users send data is provided in the mobile network, realizes that Internet resources are shared, raising utilization rate of network resource, the interface resource of especially eating dishes without rice or wine.The MBS of WiMAX definition 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 following mobile data development undoubtedly.

Two kinds of access modules of MBS business support based on the WiMAX network: single base station is inserted and many base stations are inserted.Under the access module of many base stations, having defined the MBS territory (is MBS Zone, identify with MBS zoneID) notion, so-called set that the MBS territory is exactly a base station, all base stations in MBS territory are with identical Multicast CID and MBS group Security Association (MBS Group SecurityAssociation, be called for short " MBS GSA "), send the content of same MBS Business Stream, the terminal of having registered the MBS service can receive the MBS business datum by a plurality of base stations in this MBS territory, and when the terminal that is in Idle state moves in interior span base station, MBS territory, need not rebuild connection, can impregnable reception MBS business, realize the seamless switching of MBS business.It is a kind of special case that MBS are inserted in many base stations that MBS is inserted in single base station, and MBS territory scope is defined as in the base station range, and all users of this MBS of reception use same multicast connection identifiers in MBS territory.Prior art does not have detailed description to single base station mode; But under many base station modes, how the base station sends the MBS data, and how terminal receives the MBS data, and how the base station to notify the transmission of the interested MBS data of terminal, and corresponding description is all arranged.

That eats dishes without rice or wine in the existing system mainly is described below:

At first, broadcasting connects expression (broadcasting CID) goes up the DL-MAP of broadcasting and comprises zero to one or more MBS-MAP-IE, MBS-MAP-IE last each with MBS territory ID as sign;

The second, one MBS-MAP-IE sign eats dishes without rice or wine to go up the physical resource of a MBS-MAP message of broadcasting; If single base station mode is then directly indicated the physical resource of MBS business;

The three, one MBS-MAP message can comprise zero MBS-DATA-IE to one or more MBS-DATA-IE or expansion, the physical parameter between these MBS-DATA-IE can unanimity also can be inconsistent, determine by network side; But a MBS-DATA-IE only has only a physical parameter collection;

Comprise one or more multicasts CID among the four, one MBS-DATA-IE; Why requiring a MBS-DATA-IE to comprise one is for the consideration that reduces the MBS-MAP message-length to a plurality of multicast CID, and pairing multicast CID indicates in a MBS-DATA-IE the MBS data of identical DIUC.On transfer of data, exactly the identical MAC-PDU of DIUC is placed on a physical resource Burst (burst) and goes up transmission, though the data of different MBS services have mixed in Burst, can on the MAC layer, distinguish by the multicast CID on the MAC-PDU head.Not every multicast CID is corresponding to same MBS business, but each multicast CID is corresponding to a MBS business.

Among the five, one the expansion MBS-DATA-IE, a multicast CID also comprises one or more logic channels ID.Use during logic channel ID eats dishes without rice or wine, be used for informing whether the MBS data of the current indication of terminal have its interested content;

In addition, DCD is last can carry zero to one or more MBS territory ID.According to the regulation of agreement 802.16e to content identification Content ID: this group information of Content ID and multicast CID and logic channel ID is corresponding one by one.Content ID is the upper layer data stream that is used for identifying WiMAX Access Network service flow (SF) carrying.

DL-MAP message indicates the physical resource that next MBS-MAP message sends, but does not distinguish multicast CID and the logic channel ID that comprises in the MBS-MAP message; Indication to next MBS-MAP message physical resource is also arranged among the MBS-DATA-IE, be different with the indication among the DL-MAP, the MBS-MAP message here is a special MBS-MAP message, wherein necessarily comprises a MBS-DATA-IE and has multicast CID and the logic channel ID consistent with current MBS-DATA-IE.Like this, terminal just need not to receive one by one DL-MAP message, only needs just can know from current MBS-MAP-IE the delivery time of the next MBS-MAP message of being concerned about.

In addition, also have one among the MBS-DATA-IE and change indication,, just directly receive the MBS data if do not change; Otherwise need to resolve new MBS-DATA-IE, with the relevant MBS information of new terminal more.

More than be the main description of existing protocol, yet also how do not add up the number of users specific descriptions of MBS business in the existing protocol eating dishes without rice or wine in the MBS system.

Summary of the invention

In view of this, main purpose of the present invention is to provide a kind of multicast broadcasting service user amount statistical method and terminal, makes the base station can determine to receive the number situation of the terminal of specifying the MBS business.

For achieving the above object, the invention provides a kind of multicast broadcasting service user amount statistical method, comprise following steps,

According to the user record of specifying the MBS business, statistics receives the number of the activated state terminal of this MBS business;

Specify the terminal of Multicast Channel to issue the statistics Indication message by all terminals in coverage or reception, indicate these terminals to initiate more new technological process of position, by described position more new technological process obtain the MBS business information of described terminal, receive the number of the Idle state terminal of specifying the MBS business according to the MBS business information statistics of the current Idle state terminal of obtaining;

The total number of users of the synthetic described MBS business of number of the number of activated state terminal of this MBS business and Idle state terminal will be received.

The present invention also provides a kind of terminal, comprise: state of activation is switched to idle condition or idle condition is switched to the state handover module of state of activation, and the switching of processing terminal from non-MBS service condition to the MBS service condition and the MBS state hand-off process module of switching from the MBS service condition to non-MBS service condition, it is characterized in that, comprising:

Receiver module is used to receive the base station and issues the statistics Indication message;

Administration module is upgraded in the position, be used for after receiving the statistics Indication message that the base station issues, initiating more new technological process of position, by described position more new technological process obtain the MBS business information of described terminal;

Last transmission module is used for uploading the MBS business information of state of activation or idle condition to the base station when base station all terminals or when receive specifying the terminal of Multicast Channel to issue the statistics Indication message in coverage.

By relatively finding, the main distinction of technical scheme of the present invention and prior art is, statistics receives the activated state terminal of this MBS business and the number of Idle state terminal respectively: according to the user record of specifying the MBS business, statistics receives the number of the activated state terminal of this MBS business, MBS business information according to Idle state terminal in the coverage of being obtained, statistics receive to be specified the number of the Idle state terminal of MBS business, and the number that will receive the number of activated state terminal of this MBS business and Idle state terminal afterwards synthesizes the total number of users of this MBS business.Can determine the number of activated state terminal and Idle state terminal simultaneously by this method, avoid promptly being movable to other base station or moving to this base station from other base station because of the Idle state terminal need not to switch, and the feasible number of users of specifying the MBS business of can't accurately assessing, number of users by accurate assessment MBS business, make the base station can determine currently should adopt point-to-point (Point to Point, abbreviation " PTP ") pattern still adopts a little to multiple spot (Point to Multipoint, be called for short " PTM ") carry this MBS business, make Internet resources to be maximally utilised.

Because it is professional or shift out the base station and all can trigger corresponding flow process that the activated state terminal adds MBS, can be according to corresponding flow process, add MBS activated state terminal professional or that added the MBS business when switching to this base station in terminal, add the user record of this MBS business; When the activated state terminal withdraws from MBS activated state terminal professional or that added the MBS business and switches to other base station, delete the user record of this terminal correspondence in this MBS business, when the needs statistics receives the activated state terminal number of this MBS business, only need its user record of statistics can obtain corresponding number, need not to carry out special statistics flow process, simplified the operation of network side.

Because the terminal of Idle state moves into or shifts out all informing base stations not of this base station itself, therefore in order accurately to determine the number of this part terminal, can issue the statistics Indication message by issuing page message or at special multicast and broadcast control channel, indicating terminal is initiated more new technological process of position, position by terminal more new technological process obtains the MBS business information of terminal in the coverage, receives the Idle state terminal number of specifying the MBS business thereby count.

In the statistical message that issues, can carry the probability indication, make terminal according to random algorithm, under the situation that satisfies this probability indication, initiate more new technological process of position, avoid the interior terminal of base station range to receive after statistics is indicated and initiate more new technological process of position simultaneously, make the base station to load.

If the MBS business is not set up carrying as yet, and the terminal number that the wait of current statistics receives this MBS business then stops the statistics to the Idle state terminal number that receives this MBS business greater than the thresholding of setting up the PTM mode carrying; Or, pass through PTM mode carrying MBS business in the base station, and the activated state terminal number of this MBS business of the reception of current statistics is greater than the PTM pattern during to the handoff threshold of ptp mode, or, carry the MBS business in the base station by ptp mode, and the terminal number of this MBS business of the reception of current statistics is greater than ptp mode during to the handoff threshold of PTM pattern, stop statistics to the Idle state terminal number that receives this MBS business, under the situation that does not influence base station to determine, reduce terminal and base station both sides' operation as far as possible.

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.

In the present invention, the number of users of this MBS business is added up before the professional beginning of MBS or in the professional process of playing in the base station, determines professional ptp mode or the PTM pattern of adopting of this MBS of carrying.Because at WiMAX is in the network, terminal may receive the MBS business under two states: Idle state and activated state, therefore in the present invention, in order accurately to add up each state number of users of this MBS business of reception down, the base station is added up the activated state terminal number and the Idle state terminal number of this MBS business of reception respectively, and the result who adds up according to both obtains the professional final number of users of this MBS.

Below first embodiment of the invention is described, present embodiment relates generally to MBS service-user number statistical method.In the present embodiment, the number of users of MBS business mainly contains three statistics opportunitys: the one, and when the MBS initiation of services, the base station statistics is to the number of the professional interested terminal of the current MBS that will send; The 2nd, in the professional process of transmitting of MBS, how many users base station its time of periodic statistics as required has receiving current MBS business; The 3rd, need determine current should adopt ptp mode or PTM mode carrying to specify MBS professional the time in the base station.

Statistic processes specifically as shown in Figure 2, in step 201, the base station is according to the user record of the activated state terminal of specifying the MBS business, statistics receives the number of the activated state terminal of this MBS business, and issues the statistics Indication message to the Idle state terminal.

Wherein, the user record of MBS business is when adding/withdrawing from MBS business or base station shifting in terminal by the base station, adds or deletes.

Add record and comprise following situation:

-activated state terminal adds the MBS business under this base station, in the process that adds the MBS business, the user record of corresponding MBS business is added in the base station;

-activated state the terminal that added the MBS business switches under this base station from other base stations, and the base station can obtain the information whether this terminal adds certain specific MBS business in the switch contexts transmittance process, thereby adds the user record of corresponding MBS business.

When-Idle state the terminal that added described MBS business switched to activated state, the user record of corresponding MBS business was added in the base station

Deletion record comprises following situation:

-activated state the terminal that added the MBS business initiatively withdraws from this MBS business, and in withdrawing from professional process, the user record of this terminal correspondence in this MBS business is deleted in the base station;

-activated state the terminal that added the MBS business switches to other base stations from this base station, and in the process of switching, the user record of this terminal correspondence in this MBS business is deleted in the base station.

When-activated state the terminal that added described MBS business switches to Idle state, the user record of the MBS business that the base station deletion is corresponding

In addition, because paging group changes, perhaps according to other situations that define in the existing protocol, also may trigger the Idle state terminal and carry out the position renewal, the base station may obtain the information whether this Idle state terminal adds appointment MBS business from Anchor PC in position updating process, thereby according to this information is the corresponding professional interpolation of MBS user record, but this record is irrelevant with the statistics of activated state terminal number in this step at the Idle state terminal.

Then enter step 202, the professional interested Idle state terminal of this MBS is received the statistics Indication message after, report its MBS business information by modes such as position renewals.

Then enter step 203, the base station obtains the MBS business information of Idle state terminal in its coverage in the position updating process of each terminal, receives the number of the Idle state terminal of specifying the MBS business according to the MBS business information statistics of the terminal of being obtained.

Specifically, for the statistics of Idle state terminal number, different with the activated state terminal are considered Idle state terminal situation such as may switch under the situation of informing base station not, its record is not exclusively accurate, so the base station is not added up the number of Idle state terminal according to its record.The base station can be by issuing the statistics Indication message, and indicating terminal is initiated more new technological process of position, and the position by terminal more new technological process obtains its MBS business information, and statistics receives the number of the Idle state terminal of specifying the MBS business.

The method that issues the statistics Indication message mainly contains two kinds:

One, the base station can should statistics Indication message by paging delivery, the base station can be in coverage all terminals or only specify all terminals of Multicast Channel to issue this statistics Indication message to receiving.

Comprise the MBS service identification in this statistics Indication message, this message can send in the paging cycle of base station, and for guaranteeing that terminal can receive, the base station can repeatedly send beep-page message at the timing statistics intercycle of MBS business.If current is to add up before the professional beginning of MBS, then this message can further include the Content ID (content identification) of MBS business, initiation of services time, professional range of transmission, information such as business description.After terminal is received beep-page message,,, then do not do any response if this MBS business is lost interest in according to the MBS service related information that carries in the message (as the MBS service identification); If it is interested in this MBS business, then initiate more new technological process of position, network side obtains this Idle state terminal from Anchor PC and whether adds the information of specifying the MBS business in its position updating process, receive the Idle state terminal number of this MBS business according to these Information Statistics; In addition, can also comprise a probability indication in the beep-page message, be used for the probability that the control terminal position is upgraded, be that terminal is after receiving message, if interested, then press probability and initiate the position renewal, thereby avoid the professional interested terminal of this MBS is initiated more new technological process of position simultaneously by certain algorithm in this MBS business, the network side system performance is had a negative impact, surpass the load of network side.In actual applications, terminal can be by producing random number in the full probability scope, compare with the probability indication that the base station issues, then initiating the position greater than this probability indication upgrades, less than then temporarily not initiating, continue to generate random number, compare once more, when indicating, initiate more new technological process of position greater than probability.

Perhaps, no matter during the initiation statistics, whether the MBS business begins, all can not carry any information in this MBS business statistics Indication message, or only carry a probability and indicate, the terminal of receiving this statistics Indication message is only by certain probability initiation location update operations, network side then obtains the MBS business information of Idle state terminal from Anchor PC in position updating process, judge according to the business information of each terminal whether terminal adds certain specific MBS business, and then determine the Idle state terminal number of this MBS business of current reception.

Two, the base station can use the multicast and broadcast control channel to issue this statistics Indication message.

The base station can specify the professional or all terminals of MBS to send the statistics Indication message to receiving by to custom-designed multicast and broadcast control channel.Monitor this Indication message by terminal by the cycle of setting, in measurement period, the base station can repeatedly send Indication message by the cycle, can both receive this message to guarantee all to the professional interested terminal of MBS.Equally, can carry following information in the message: MBS service identification, Content ID, initiation of services time, professional range of transmission, business description, access probability indication etc.

After terminal is received Indication message,, then do not do any response if corresponding M BS business is lost interest in; If it is interested, then the mode of upgrading by the position is fed back, network then obtains the MBS business information of this Idle state terminal from Anchor PC in its position updating process, determine whether it adds the MBS business of appointment, and then judge the number of the Idle state terminal of this MBS business of current reception.

In addition, statistics to the MS of Idle state can also make with the following method: for the Idle state terminal that adds the MBS business, when other base stations move to this base station, if this base station also can provide this MBS business, then terminal can be initiated position updating process one time, position updating process is passed through in the base station, can obtain the Anchor PC address that this terminal has added information He this terminal of this MBS business equally, and it is kept in the context of base station, so that the base station can obtain the current MBS business information of this terminal according to the Anchor PC address of this terminal of being preserved when carrying out the Idle state terminal number statistics of corresponding MBS business.Equally, when terminal when activated state enters Idle state, corresponding information is also preserved in the base station.

After the base station counts the Idle state terminal number, then enter step 204, the base station will receive the total number of users of synthetic this MBS business of number of the number of activated state terminal of this MBS business and Idle state terminal.

What deserves to be mentioned is, be in order to select suitable pattern (ptp mode or PTM pattern) to carry this MBS business if the purpose of this MBS service-user number is added up in the base station, then can also carry out following change to above flow process:

Add up for the number of users when the MBS business is set up, the terminal number that adds this MBS business under the activated state can at first be added up in the base station, if this number is greater than " setting up the thresholding of PTM carrying ", then can directly determine bearing mode, need not again the Idle state terminal to be added up, promptly need not to issue the statistics Indication message; " do not set up the thresholding of PTM carrying " if reach this, then the base station can further issue the statistics Indication message, triggering terminal is initiated the position and is upgraded, and by inquiring about the record of Anchor PC/LR, preliminary definite current wait receives the terminal number that is in Idle state of this MBS business, this number and the addition of activated state terminal number are drawn a total number of users, when this number of users reaches " thresholding of setting up the PTM carrying ", the base station should stop statistics, can eat dishes without rice or wine to send the Indication message that stops to add up to the terminal that does not also have feedback, send mode is consistent with the send mode of statistics Indication message, but the information of carrying in the message is the statistics that stops certain or all MBS business; If once adding up the number of users of feedback, the base station do not reach " thresholding of setting up the PTM carrying ", base station or ASN can send the statistics Indication message once more so, the user that (not upgrading as initiating the position) fed back in indication as yet continues feedback, probability indication in the message can reduce, so that can more easily initiating the position, terminal upgrades, this process can be carried out repeatedly, reach " thresholding of setting up the PTM carrying " up to the statistics number of users, if number of users never reaches in the timing statistics of setting " thresholding of setting up the PTM carrying ", then stop to issue the statistics Indication message.

Add up for the number of users in professional transmission course, the base station can at first be added up the terminal number that adds this MBS business under the activated state equally, professional what use is the PTM carrying to this MBS if the base station is current, and the activated state terminal number that counts is greater than " PTM is to the PTP switching threshold ", then need not again the Idle state terminal to be added up, promptly need not to issue the statistics Indication message; If do not reach this " PTM is to PTP switching threshold ", then the base station can further issue the statistics Indication message, triggering terminal is initiated the position and is upgraded, and by inquiring about the record of Anchor PC/LR, the preliminary terminal number that is in Idle state of determining this MBS business of current reception, this number and the addition of activated state terminal number are drawn a total number of users, if this number of users is greater than " PTM changes the threshold value of PTP ", then the base station should stop statistics, and can eat dishes without rice or wine to send the Indication message that stops to add up to the terminal that does not also have feedback, send mode is consistent with the send mode of statistics Indication message, and just the information of carrying in the message is the statistics that stops this MBS business; If the number of users of feedback is once added up not greater than " PTM is to the PTP switching threshold " in the base station, base station or ASN can send the statistics Indication message once more so, indicate those users that do not have feedback to continue feedback, access probability indication in the message can reduce, so that terminal can easier initiation position new technological process more, this process can be carried out repeatedly, up to the number of users that counts greater than " PTM is to the PTP switching threshold ", if number of users never reaches " PTM is to the PTP switching threshold " in the timing statistics of setting, then stop to issue the statistics Indication message.

Add up for the number of users in professional transmission course, professional what use is the PTM carrying to this MBS if the base station is current, the base station can at first be added up the terminal number that adds this MBS business under the activated state equally, and the activated state terminal number that counts is greater than " PTP is to the PTM switching threshold ", then need not again the Idle state terminal to be added up, promptly need not to issue the statistics Indication message; If do not reach this " PTP is to PTM switching threshold ", then the base station can further issue the statistics Indication message, triggering terminal is initiated the position and is upgraded, and by inquiring about the record of Anchor PC/LR, the preliminary terminal number that is in Idle state of determining this MBS business of current reception, this number and the addition of activated state terminal number are drawn a total number of users, if this number of users is greater than " PTP is to the PTM switching threshold ", then the base station should stop statistics, and can eat dishes without rice or wine to send the Indication message that stops to add up to the terminal that does not also have feedback, send mode is consistent with the send mode of statistics Indication message, and just the information of carrying in the message is the statistics that stops this MBS business; If the number of users of feedback is once added up not greater than " PTP is to the PTM switching threshold " in the base station, base station or ASN can send the statistics Indication message once more so, indicate those users that do not have feedback to continue feedback, access probability indication in the message can reduce, so that terminal can easier initiation position new technological process more, this process can be carried out repeatedly, up to the number of users that counts greater than " PTP is to the PTM switching threshold ", if number of users never reaches " PTP is to the PTM switching threshold " in the timing statistics of setting, then stop to issue the statistics Indication message.

Usually, for fear of producing ping-pong, " PTP is to the PTM switching threshold " often is arranged to more than or equal to " PTM is to the PTP switching threshold ", generally requires greater than certain value.

Below second embodiment of the invention is described, second execution mode relates to a kind of terminal, as shown in Figure 3, comprise: state of activation is switched to idle condition or idle condition is switched to the state handover module 304 of state of activation, and the switching of processing terminal from non-MBS service condition to the MBS service condition and the MBS state hand-off process module 305 of switching from the MBS service condition to non-MBS service condition, be used to receive the receiver module 301 that the base station issues the statistics Indication message, after the statistics Indication message that is used for issuing in the reception base station, initiate more new technological process of position, more upgrade administration module 302 in the new technological process position that obtains the MBS business information of described terminal by described position; And be used for uploading the last transmission module 303 of the MBS business information of state of activation or idle condition to the base station when base station all terminals or when receive specifying the terminal of Multicast Channel to issue the statistics Indication message in coverage.

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.

9. according to each described multicast broadcasting service user amount statistical method in the claim 1 to 8, it is characterized in that, before the professional beginning of described MBS, carry out the number of users statistics of this MBS business; Or

After the professional beginning of MBS, periodically carry out the number of users statistics of this MBS business.

10. according to each described multicast broadcasting service user amount statistical method in the claim 1 to 8, it is characterized in that, if described MBS business is not set up carrying as yet, and the wait of current statistics receives the terminal number of this MBS business greater than the thresholding of setting up the point to multipoint mode carrying, then stops the statistics to the Idle state terminal number that receives this MBS business;

If carry described MBS business by point to multipoint mode, and the terminal number of this MBS business of the reception of current statistics then stops the statistics to the Idle state terminal number that receives this MBS business greater than the handoff threshold of point to multipoint mode to point-to-point mode;

If carry described MBS business by point-to-point mode, and the terminal number of this MBS business of the reception of current statistics then stops the statistics to the Idle state terminal number that receives this MBS business greater than the handoff threshold of point-to-point mode to point to multipoint mode.

11. terminal, comprise the state handover module that state of activation is switched to idle condition or idle condition is switched to state of activation, and the switching of processing terminal from non-MBS service condition to the MBS service condition and the MBS state hand-off process module of switching from the MBS service condition to non-MBS service condition, it is characterized in that, comprising:
