Description
Technical field
The present invention relates to the mobile broadcast technology, particularly a kind of method that in mobile broadcast system, sends a notification message.
Background technology
Along with the fast development of internet, a large amount of multimedia services emerge in large numbers synchronously, and people also begin the requirement mobile communication can support multimedia service.Wherein, mobile video becomes the topic an of the supreme arrogance of a person with great power at home and abroad gradually.The bearer network implementation of mobile video mainly can be divided into following several: first kind of mode that is based on terrestrial broadcasting comprises digital video hand-held broadcasting (DVB-H) technology in Europe, terrestrial digital multimedia broadcasting (T-DMB) technology of Korea S etc.; Second kind of mode that is based on satellite transmission comprises European digital multimedia broadcast (dmb) via satellite (SDMB) technology; The third then is based on mobile network's the middle multimedia broadcasting of third generation partner program (3GPP) and multicast service (MBMS) technology, BroadCast MultiCast Service (BCMCS) technology and stream media technology.
In addition, also have a kind of application layer technology that has nothing to do with bearer network, comprise channel content audio/video coding, electron service instruction, content protecting technology and service authentication, user management and charging etc.Relevant standardization group is woven with digital video broadcasting (DVB) tissue, broadcasting and mobile service convergence (CBMS) working group, Open Mobile Alliance (OMA) tissue and broadcasting group (BCAST) etc.Utilize the application layer technology can directly utilize the IP programme content that has now on the Internet network, broadcast to the user by radio network, thereby protected existing content resource to the full extent.Its basic networking structure schematic diagram as shown in Figure 1, wherein, broadcast application is positioned at IP network, links to each other with radio network via IP packing (IPE) equipment, is responsible for key functions such as real time programme broadcasting, electron service instruction assembling transmission, programme content encryption, notification message transmission; Client's Operation Server links to each other with the Internet, and being responsible for the terminal use provides program to buy the purchase request and the customer service functions of information, reception and process user.User terminal has the ability of visiting the radio network and the Internet simultaneously.
Application layer comprises that a kind of very important function is exactly an informing function, is used in mobile broadcast system sending message to notify some imminent incidents by operator to user or terminal, is convenient to the user or terminal is handled accordingly.Can be divided into following three kinds of situations from the angle informing function of service operation:
1, default notification business: be exactly and the notice of concrete independent of service, generally be used for sending some paroxysmal message, system failure notice for example, sudden disaster event notice;
2, service related notification: with concrete professional relevant informing business, when for example the user watches program, one of a certain crucial plot transmission with lottery question-and-answer problem answer the TV guide message that certain is professional etc. to the user;
3, independent informing business: with concrete independent of service, can select to subscribe to, may need to charge and encrypt, for example Shou Fei weather forecast information as an independently professional user of confession.
Comprise following parameter in the message body of notification message: business or content, the caption text of message, the content of text of message, the ways of presentation of message and the outside of message under the type of the transmitting time of message id, message and version, notice, the valid expiration date of message, the message are connected.Wherein, professional corresponding channel, a certain specific program in the corresponding channel of content.
At present, in mobile broadcast system, what professional transmission was adopted is the timeslice technology, the timeslice technology is the important protocol-at one of characteristic in the digital video broadcasting (DVB-H) of portable terminal of current mobile broadcast field physical layer, its principle is the DVB-H physical channel is divided into a plurality of segments according to the time, each segment is called timeslice burst (Time Sliced Burst), the a plurality of business that transmit in the channel respectively take a Time Sliced Burst, as the professional 1-3 among Fig. 2, professional 4 for there not being the business of elapsed time sheet processing, and it can coexist in channel with the business that the elapsed time sheet is handled.All professional Time Sliced Burst form burst (Burst) cycle, and in the cycle, each business will occur in one's own Time Sliced Burst, goes round and begins again at each Burst.Like this for terminal, if subscribed to certain business, then only need receiving system be opened reception information belonging to this professional TimeSliced Burst, section At All Other Times in the same Burst cycle then can be closed receiving system, thereby can reach the purpose of saving electric power, relevant test data shows that the electric weight of saving can reach 90%.
But at present notification message mainly is to be handed down to terminal and terminal is obtained by modes such as notes by the radio network or the Internet, and can't use the notification message that the timeslice technology sends IP based network.Because, timeslice of all data sharings in the same element flow (ES) that the elapsed time sheet is handled, but can encapsulate a plurality of IP streams in the ES stream, that is to say, during flowing, an ES encapsulates the notification message of a plurality of business possibly, and as long as in the ES stream any one professional notification message is arranged, terminal will go to receive the next timeslice of this ES stream according to the time interval parameter in the timeslice, and next timeslice data carried by data may be other professional notification message, is not the notification message that terminal is wanted the business that receives.
In addition, in a single day the timeslice next time that comprises in the current time sheet issues apart from the time interval parameter of current time, just can not revise, and can't satisfy the demand that the plan of application layer messages notice may be changed.

When the message body of notification message carry be the renewal in time interval that a last notification message is carried the time, the time type parameter of setting is 2.
Broadcast application is provided with 3 time interval parameters in notification message, in order to show subsequently send belong to the delivery time of the notification message of same business or content with this notification message:
Time interval parameter 1 shows belonging to of first transmission subsequently of same business or the transmitting time of the notification message of content, represents that with the form of relative time promptly next message is apart from the time interval of current message;
Time interval parameter 3 shows the transmitting time of the notification message that belongs to same business or content of the 3rd transmission subsequently, represents with the form of relative time.
After setting was finished, broadcast application sent to terminal with notification message.
After step 202, terminal receive notification message, resolve described notification message, the business or the content of record notification message ownership, and judge whether self has subscribed to this business or content, if then execution in step 203; Otherwise execution in step 207.
Whether step 203, terminal judges notification message carry time type parameter and time interval parameter, if then execution in step 204; Otherwise execution in step 207.
For further describing above flow process, following Example is that terminal is upgraded timer according to the time parameter in the notification message and received the flow process of message subsequently, and its flow chart is specifically carried out following steps as shown in Figure 4:
Step 301, constantly 1, broadcast application utilizes the default notification business to send a notification message 1 to the booking reader at radio network, the time parameter type is 1, transmission time interval parameter 1 is the time interval of the transmitting time (moment 1) of current message to the transmitting time (moment 2) of next bar notification message, and time interval parameter 2 and 3 is 0;
Step 302, constantly 2, broadcast application sends the notification message 1 of related announcement business, the time parameter type is 1, the transmission time interval parameter comprises the time interval of nearest three notification messages, a wherein nearest notification message 3 is sending constantly;
Between step 303, the moment 2 and the moment 3, the transmission plan of a nearest notification message is delayed to the moment 4, if server is left intact, terminal will not receive corresponding notification message in the moment 3 in the original plan; For this situation, can adopt dual mode: I) broadcast application 3 is sending the notification message that belong to same business or content 1 of a content for sky constantly, the time parameter type is 2, this notification message corresponding service or content is arranged in the message, and carry after changing transmission time interval parameter, II) time change message of the professional transmission of server by utilizing default notification, the time parameter type is 2, this notification message corresponding service or content is arranged in the message, and carry transmission time interval parameter after changing; What adopt among Fig. 4 is I kind mode;
Step 304, constantly 4, broadcast application sends the notification message 2 through the related announcement business that postpones, the time type parameter in the message is changed to 1, and following 3 notification message transmission timers are set simultaneously;
Between step 305, the moment 4 and the moment 5, the plan that broadcast application sends a nearest notification message shifts to an earlier date, promptly the transmitting time of 7 notification message is the moment 6 in advance constantly, if server is left intact, terminal will not receive corresponding notification message in the moment 7 in the original plan; The notification message 2 of server by utilizing default notification business 5 is sending a time change message constantly, and the time parameter type is 2, and this notification message corresponding service or content is arranged in the message, and carries transmission time interval parameter after changing;
Step 306, constantly 6, broadcast application sends the notification message 3 through related announcement business in advance, the time type parameter in the message is changed to 1, and notification message transmission timer subsequently is set simultaneously;
Step 307, constantly 7, the notification message 3 of the related announcement business that sends does not send in the original plan, but terminal learns in advance, do not receive.
In above flow process, the default notification business should send simultaneously with the timeslice burst of each main business, and so no matter which business is terminal select to watch, can get access to the default notification business in corresponding timeslice burst.
In the present invention, for broadcast application, the transmission plan of aware notification message in advance, and plan takes place under the less situation of the probability of change, the method that adopts the present invention to propose, and it realizes that effect is preferable; If it is very frequent that the notification message transmitting time changes, even can't predict, can cause too much redundant extra Notification of Changes message, can lose more than gain.
In addition, consider that Network Transmission may postpone, message can a little later reach than the time of plan, terminal according to schedule the time receive signal, wait for that certain error time just can receive signal more.Terminal can be taked certain optimized Measures to this problem, for example in the arrival error of statistics all notification messages during this period of time (difference of the plan time of advent and actual time of arrival) at set intervals, minimal error in inciting somebody to action during this period of time then is a reference value the most, planned time can be added this reference value during follow-up reception message, as the time of actual reception message.
Under unusual situation, if terminal is not received article one notification message, and do not receive any Notification of Changes yet, then continue to intercept the affiliated ES stream of this informing business, till article one message of receiving this informing business.
It should be noted last that, above embodiment is only unrestricted in order to technical scheme of the present invention to be described, although the present invention is had been described in detail with reference to preferred embodiment, those of ordinary skill in the art is to be understood that, can make amendment or be equal to replacement technical scheme of the present invention, and not break away from the spirit and scope of technical solution of the present invention.
