Wherein, in the time of the corresponding multiple broadcast task of this MBMS content, off-the-air time corresponding to MBMS content arrives and comprises that the off-the-air time of setting time broadcast task corresponding to this MBMS content of broadcast arrives, concrete setting time can be set as required flexibly, for example, corresponding 6 the broadcast tasks of this MBMS content, in order to ensure the real-time of MBMS content, can after the 3rd off-the-air, obtain receiving status information corresponding to this MBMS content, if when not getting corresponding receiving status information or determining that according to the receiving status information obtaining user receives this MBMS content failure, indicating user obtains this MBMS content again from network side, for example adopt point-to-point mode to download.

In further embodiment of this invention, above-mentioned terminal 200 also for:

The MBMS content receiving is carried out to completeness check, in the time determining that the MBMS content receiving is imperfect, again obtain in this MBMS and perhaps obtain from network side the content that this MBMS content is not acquired from network side.

In said system, the more specifically function that MBMS server 100 and terminal 200 realize will be described in more detail in the following embodiments.

As shown in Figure 2, the implementation method flow chart of the MBMS providing for the embodiment of the present invention, as seen from Figure 2, this implementation procedure mainly comprises the steps:

Step 201, terminal are obtained the broadcast time information of MBMS from MBMS server.

In this step, the broadcast time information that terminal is obtained can comprise each MBMS content corresponding broadcast task number of times and radio slot information corresponding to the task of at every turn broadcasting respectively.

Broadcast time started corresponding to its customized MBMS content in step 202, terminal monitoring broadcast time information.

Step 203, judge whether this broadcast time started arrive, if so, perform step 204, otherwise return to step 202.

Step 204, monitor broadcast channel corresponding to this MBMS content, and receive corresponding MBMS content.

In further embodiment of this invention, before carrying out above-mentioned steps 201, terminal needs customized corresponding MBMS content from MBMS server in advance, for example, customized mobile newspaper service content, stock market business tine etc., subscription process is as follows:

Terminal sends MBMS subscribe request to MBMS server, particularly, terminal can by specify customer service number send given content note, dial the customized MBMS of variety of way such as customer service phone or WAP;

After the subscribe request of MBMS server receiving terminal, return to customized success response to terminal.Preferably, after the subscribe request of MBMS server receiving terminal, this terminal is verified, for example, the available balance of authentication of users, when being verified the customized success response of backward terminal feedback.

After the customized MBMS success of terminal, MBMS client-requested MBMS server in terminal issues the broadcast time information of MBMS, wherein, this broadcast time information comprise user mark ID corresponding to customized MBMS, issue the information such as the frequency (broadcasting the number of times of task), concrete period, for example, issue on every Mondays once, the period is 9:00 to 10:00, or every day issue once, the period is 8:00 to 9:00.

In the embodiment of the present invention, the form of broadcast time information can arrange as required flexibly, for example, can broadcast time information be represented to user by form, specifically as shown in Table 1:

Table one:

Title	Type	Whether essential	Corresponding relation	Describe	Data type
						ID	A	NM/TM	1	The mark of the business that this burst is described	anyURI
Frequence	E1		1	Specify the purposes of the data that this preview data burst provides: the fixed cycle does not issue once a day every twice-daily every day three times
						StartTime	E1	NM/TM	0…1	Represent the time started of this program to user, by the embedded data class of XML	Time

				Type ' Time ' is expressed
						EndTime	E1	NM/TM	0…1	Represent the end time of this program to user, express by the embedded data type of XML ' Time '	Time
StartDateTime	E1	NM/TM	0…1	Represent the time started of this program to user, express by the embedded data type of XML ' DateTime '	DateTime
						EndDateTime	E1	NM/TM	0…1	Represent the end time of this program to user, express by the embedded data type of XML ' DateTime '	DateTime

According to the embodiment of the present invention, the mode that issues of the broadcast time information of MBMS can arrange flexibly, for example, can adopt following two kinds of modes:

Mode one, after the customized MBMS of user success, MBMS server can initiatively be handed down to user terminal by broadcast time information corresponding MBMS customized user.MBMS server also can periodically update MBMS broadcast time information and be handed down to terminal.

Preferably, for the ease of promoting service, MBMS server, in the time issuing the customized MBMS broadcast time information of user, can also issue the not customized MBMS broadcast time information of user and select customized as recommendation information for user.

Mode two, after the customized MBMS of user success, user terminal requests MBMS server issues the broadcast time information that its customized MBMS is corresponding.User terminal also can periodically update the MBMS broadcast time information obtaining, for example, can after each start, issue the broadcast time information that its customized MBMS is corresponding by request MBMS server, also can regular request MBMS server issue the broadcast time information that its customized MBMS is corresponding and upgrade local broadcast time information.

In above-mentioned steps 202, in monitoring broadcast time information, user can adopt the mode that timer is set customized broadcast time started corresponding to MBMS content, that is:

Timer is set according to broadcast time started corresponding to the customized MBMS content of user, so that (broadcast time started) startup MBMS client is monitored broadcast channel corresponding to MBMS content when timer arrives, receiving broadcast signal, obtains corresponding MBMS content.

Wherein: the situation that MBMS content correspondence repeatedly issues, its broadcast time started can be the broadcast time started while issuing for the first time, also can time corresponding broadcast time started while again issuing.If only provided broadcast time started and broadcast mission bit stream that MBMS content issues for the first time in broadcast time information corresponding to the customized MBMS of user, the broadcast time started that can issue for the first time according to this MBMS content and broadcast mission bit stream are determined the broadcast time started corresponding while again issuing, for example, the broadcast time started that MBMS content issues is for the first time 7:00, broadcast mission bit stream is often to issue once through 5 hours, can determine that the broadcast time started again issuing is 12:00, the like.

Be to be understood that, the mode that employing arranges timer is only in the embodiment of the present invention, to monitor the customized MBMS content of user in broadcast time information a kind of mode of corresponding broadcast time started, as required, the monitoring mode of broadcast time started can be set flexibly, not enumerate herein.

According to the embodiment of the present invention, in the time that step 203 judges that this broadcast time started arrives, can new timer be set according to broadcast time information corresponding to this MBMS, the triggered time of timer is the time started of this MBMS content broadcast next time.

In further embodiment of this invention, terminal this locality is provided with the journal function whether monitoring content receives, will be in daily record after each broadcasted content receives record in addition, receive after MBMS content each, the record receiving status information corresponding with MBMS content in daily record, for example, receive the time started, receive the information such as end time.Wherein, MBMS content of every reception is all that this MBMS content is set up a daily record, each MBMS content receiving is corresponding one by one with daily record, in practical application, can be the mark ID of MBMS content assignment receiving, this ID is for identifying the daily record corresponding with this MBMS content, i.e. receiving status information.

In the embodiment of the present invention, the main purpose that journal function is set is determine according to the receiving status information recording in this daily record whether terminal receives its customized MBMS content, and specifically as shown in Figure 3, deterministic process is as follows:

Step 301, determine the off-the-air time corresponding to MBMS content of current broadcast.

In this step, can determine the off-the-air time that it is corresponding by the broadcast time information corresponding to MBMS content of inquiry current broadcast, also can be by the off-the-air time of inquiry set timer.

Step 302, judge whether the off-the-air time corresponding to MBMS content of current broadcast arrive, if so, perform step 303, otherwise continue to wait for.

Step 303, obtain the daily record corresponding with this MBMS content (being receiving status information).

Step 304, judge whether to get the daily record corresponding with this MBMS content, if so, perform step 305, otherwise execution step 306.

The daily record that step 305, basis are obtained, adjusts the clock synchronous in terminal and MBMS server.

In this step, can be by the reception time started of the MBMS content recording in daily record, reception end time be contrasted with time started, the end time of this MBMS content time broadcast respectively, determine whether terminal synchronizes with MBMS server, and determining when asynchronous, the clock of calibrating terminal and MBMS server in time, avoids causing because clock is asynchronous terminal to receive the delay of MBMS.

Step 306, from MBMS server, again obtain this MBMS content.

In this step, terminal can be passed through the modes such as Http mode, WAP and from MBMS server, download the MBMS content not receiving, while specifically obtaining, can in the request of obtaining, carry broadcast time started and the off-the-air time of the MBMS content that need to obtain, MBMS server can be searched corresponding MBMS content according to the broadcast time started of this MBMS content and off-the-air time, and offers terminal.

In further embodiment of this invention, receiving after MBMS content, can further carry out completeness check to the MBMS content receiving, mainly can be by following two kinds of mode verifications:

Mode one:

The daily record corresponding with MBMS content adjusted the clock synchronous in terminal and MBMS server except being used for, and can also be used to the integrality of the MBMS file of judgement reception, that is:

By the reception time started of the MBMS content recording in daily record, broadcast time started, off-the-air time corresponding with this MBMS content contrasts respectively to receive the end time;

If the reception time started that comparing result is terminal is identical with the time started of MBMS server broadcast MBMS content, and the reception end time of terminal is identical with the end time of MBMS server broadcast MBMS content, determine the MBMS content intact receiving, otherwise, determine that the MBMS content receiving is imperfect.

According to the embodiment of the present invention, in the time determining that the MBMS content receiving is imperfect, further acquisition request MBMS content, again obtains in this MBMS and perhaps obtains from MBMS server the part MBMS content not getting from MBMS server; Or

In the time determining that the MBMS content receiving is imperfect, according to broadcast task number of times corresponding to this MBMS content and radio slot information corresponding to the task of broadcasting at every turn, determine whether this MBMS content exists the broadcast task not starting; Broadcast time started of the broadcast task if so, not starting in this MBMS content is while arrival, monitor broadcast channel corresponding to this MBMS content and receive the full content of this MBMS or this MBMS content in the content that is not acquired; If not, in obtaining this MBMS again, network side perhaps obtains from network side the content not being acquired this MBMS content.

Wherein, while obtaining the part MBMS content not being acquired, first will determine the part MBMS content not being acquired from MBMS server, concrete deterministic process is as follows:

Determine the MBMS content not being acquired according to the daily record of record, the time started, the end time that receive MBMS content by terminal in daily record contrast with MBMS content actual broadcast time started, off-the-air time respectively, determine the radio slot of the MBMS content that do not get according to comparing result, and from MBMS server MBMS content corresponding to this period of acquisition request.For example:

The reception time started of the log recording corresponding with MBMS content: 7:00, reception end time: 9:00;

The actual broadcast time started of this MBMS content: 7:00, off-the-air time: 10:00;

Can determine that by the time contrasting in above-mentioned two records the MBMS content not being acquired is the MBMS content in 9:00～10:00 broadcast, terminal accordingly request server only issues the MBMS content in 9:00～10:00 broadcast, and without obtaining whole MBMS content, saved Internet resources and again obtained the efficiency of MBMS content.

Mode two,

When actual broadcast MBMS content, generally issue with document form, each file is divided into again multiple content fragments, when the MBMS content receiving in checking is carried out integrality, first judge that whether content fragment number corresponding to MBMS content receiving be identical with the content fragment number of this MBMS content broadcast, if identical, determine the MBMS content intact receiving, otherwise, determine that the MBMS content receiving is imperfect.

In the time determining that the MBMS content receiving is imperfect, according to broadcast task number of times corresponding to this MBMS content and radio slot information corresponding to the task of broadcasting at every turn, determine whether this MBMS content exists the broadcast task not starting; Broadcast time started of the broadcast frequency if so, not arriving in this MBMS content is while arrival, monitor broadcast channel corresponding to this MBMS content and receive the full content of this MBMS or this MBMS content in the content that is not acquired; If not, in obtaining this MBMS again, network side perhaps obtains from network side the content not being acquired this MBMS content in point-to-point mode.

Terminal can check that burst sequence number judges whether the complete MBMS of receiving file content, and using MBMS content corresponding the burst sequence number not being checked through in terminal as the MBMS content not being acquired, request MBMS server re-issues.

The technical scheme providing in order to understand better the embodiment of the present invention, below taking the customized MBMS of user as mobile newspaper service is as example, the interaction flow of each inter-entity is described in detail when realizing MBMS, specifically as shown in Figure 4, comprises the steps:

MBMS client-requested MBMS server in step 401, terminal issues broadcast time information corresponding to the customized mobile newspaper service of user;

Step 402, MBMS server are to the broadcast time information of the MBMS client feedback mobile phone newspaper in terminal;

Step 403, MBMS client arrange timer according to the broadcast time started of mobile phone newspaper;

Step 404, mobile newspaper service platform before the predetermined broadcast time started, by mobile phone newspaper content uploading to be broadcast to MBMS server;

Step 405, MBMS server, in the time that the predetermined broadcast time started arrives, issue mobile phone newspaper content;

Step 406, MBMS server issue after mobile phone newspaper content, and recorded announce result (comprising actual beginning, the end time of broadcast, the information such as carousel number of times), so that keeper's subsequent query;

When MBMS client control in step 407, terminal arrives to timer, monitor MBMS broadcast channel, receive mobile phone newspaper; Set new timer, the time expires and is a little set as broadcast time started next time simultaneously;

Step 408, terminal after the mobile phone newspaper content reception of each broadcast in local log recording record in addition; Wherein, the information recording in daily record: the context number of receiving broadcast content, unique separately context number (ContentID) mark for broadcasted content that needs each time terminal to receive.Terminal only need check in the log that receives content whether some context numbers exist and just can know whether this broadcasted content receives;

The laggard row file integrality of the complete broadcasted content of MBMS client in step 409, terminal is differentiated, and repairs flow process (for example, the point-to-point downloading mode of GPRS) obtain complete file content in the time that file is imperfect by file;

Step 410, MBMS client, after off-the-air, are analyzed local log recording and broadcasting schedule, judge whether the broadcasted content in each airtime section successfully obtains; If terminal is because signal reason all cannot receive MBMS broadcasted content at whole radio slot, or because the reasons such as user's shutdown have been missed radio slot, can initiate Http mode download request to MBMS platform so, platform authentication judges that this user is really after customized this MBMS, and terminal can be downloaded and obtain corresponding business tine; Meanwhile, platform need carry out record to information such as the Subscriber Number of this download, type of service, download times, adds up in order to the broadcast reception situation to MBMS;

Step 411, MBMS client resolve to multimedia message files after obtaining the complete content of mobile phone newspaper;

Multimedia message client in step 412, MBMS client notification terminal is obtained multimedia message;

Step 413, multimedia message client have the notice of new multimedia message by multimedia message interface prompt user, check new mobile phone newspaper multimedia message for user.

Should be appreciated that step defined in above flow process only for convenience of description, does not limit as the sequencing of carrying out.

In a preferred embodiment of the invention, after the broadcast time information that terminal issues at reception network side, monitor broadcast time started corresponding to MBMS content in this broadcast time information, specifically comprise:

Corresponding the last time is broadcasted the corresponding broadcast time started to the MBMS content that monitoring does not respectively get respectively.

In a preferred embodiment of the invention, terminal is getting after the broadcast time information that network side issues, determine the current MBMS content of self not obtaining and broadcasting that whether exists according to the broadcast time information receiving, if determine while there is the MBMS content of self not obtaining and broadcasting, monitor broadcast channel corresponding to this MBMS content of broadcasting and not being acquired and receive this MBMS content.

In a preferred embodiment of the invention, the daily record (receiving status information) of terminal pins to MBMS content record can also further send to MBMS server, the log information being sent according to terminal by MBMS server determines that terminal receives the situation of MBMS content, determine do not received by terminal and off-the-air (in the time that multitask is broadcasted, the situation of the off-the-air of corresponding last task) MBMS content, and ID (mark) information corresponding the MBMS content of determining is sent to terminal;

Terminal receives after the MBMS identification information that network side sends, and obtains it and do not get and the MBMS content of off-the-air the MBMS server of specifying from network side according to this expression, for example, adopts point-to-point mode download etc.

Further, terminal is obtained it and is not got and after the MBMS content of off-the-air, record the daily record corresponding with this MBMS content, comprising the receiving status information for this MBMS content, and this receiving status information is fed back to network side, determined whether also to exist by network side and do not received by terminal and the MBMS content of off-the-air, and will determine that existence is not received by terminal and when the MBMS content of off-the-air, upgrade not getting and the identification list of the MBMS content of off-the-air of issuing to terminal, and send to terminal.

In the embodiment of the present invention, adopt point-to-point mode to obtain and do not obtained by terminal and the MBMS of broadcast reception identifies corresponding MBMS content from network side, more preferably can adopt following various ways:

Mode one

When in monitoring broadcast time information, broadcast time started corresponding to MBMS content do not arrive, adopt point-to-point mode to obtain the MBMS content corresponding with this mark from network side, before the airtime arrival of MBMS content that is about to broadcast, utilize idle period to download the MBMS that has finished broadcast from network side, and after download completes, enter the flow process of monitoring by the broadcast time started of the MBMS content of broadcast.

Preferably, while adopting this kind of mode, if after download completes, be about to the broadcast time started mistake of the MBMS content of broadcast, enter the corresponding broadcast channel of monitoring this MBMS content the flow process that receives this MBMS content, and obtain by the flow process of the MBMS content receiving being carried out to completeness check the MBMS content not being acquired, or determine the fragment of the MBMS content of not obtaining, in the time broadcasting next time, obtain.

Mode two

After monitoring broadcast channel corresponding to MBMS content and receiving this MBMS content, adopt point-to-point mode to obtain the MBMS content corresponding with described mark from network side, preferentially obtain the MBMS content that is about to broadcast, and after this MBMS content broadcast finishes, section is downloaded the MBMS content that has finished broadcast from network side at one's leisure.

Mode three

Broadcast time started corresponding to MBMS content that is about to broadcast in monitoring broadcast time information be not while arrival, adopt point-to-point mode to obtain not get with this terminal and the MBMS content corresponding to mark of the MBMS content of off-the-air from network side, and in the time arriving by broadcast time started corresponding to MBMS content, suspend and obtain the MBMS content corresponding with this mark from network side, and after monitoring broadcast channel corresponding to MBMS content and receiving this MBMS content, continue to adopt point-to-point mode to obtain the MBMS content corresponding with this mark from network side.

Adopt this kind of mode can effectively utilize idle period to carry out not obtained by terminal and the download flow process of the MBMS content of off-the-air.

Below in conjunction with mode two, the implementation procedure of MBMS in the preferred embodiment of the present invention is described in detail; be to be understood that; the concrete ins and outs that relate in following examples are to implement the better or usual way of the embodiment of the present invention; only for explaining the embodiment of the present invention, and can not be in order to limit protection range of the present invention.

As shown in Figure 5, the implementation procedure of MBMS comprises the steps:

Step 501, terminal enter and receive broadcast flow process.

In this step, terminal enters reception broadcast flow process and obtains the business guide that MBMS is relevant, particularly, obtains business guide and can pass through service instruction request interface.

Step 502, report local log list, and obtain the broadcast time information that MBMS server issues and need the ID list of the MBMS content that point-to-point mode downloads.

In this step, the local log list of terminal to report comprises ID corresponding to MBMS content having obtained; The ID list of the MBMS content that the point-to-point mode of needs of obtaining is downloaded comprises that terminal that network side is determined according to the local log list of terminal to report is not obtained and the ID of the MBMS content of off-the-air.

And, preferably, the broadcast time information obtaining in this step is the interval of distance broadcast next time this service broadcast time started point, owing to once broadcasting and may hold at short notice repeatedly, therefore the time interval can comprise N parameter value, and the time interval that representative starts to the 1st broadcast now respectively and afterwards each broadcast start the time interval between time point.

The broadcast time information that step 503, basis are obtained judges the current MBMS content of broadcasting that whether exists, and if so, performs step 504～step 505, if not, and execution step 506.

In this step, judge that according to the broadcast time information obtaining the current MBMS content of broadcasting that whether exists judges whether current time is zero to the time interval that broadcast starts next time, if this time interval is zero, this content is now being broadcasted in explanation.

Step 504, access TD-MBMS channel receive the current MBMS content of broadcasting, until this off-the-air.

In this step, if in the process of reception MBMS content, there is the situation of receiving terminal, the situations such as such as jitter, can be by the MBMS content receiving be carried out to completeness check after this MBMS content broadcast finishes, download this MBMS content and do not get to obtain part, realization flow will illustrate in subsequent embodiment in detail, wouldn't illustrate herein.
