Certainly professional or data (for example PSI/SI) also can be handled without timeslice, and like the business among Fig. 25, this type of business can coexist in channel with the business that the elapsed time sheet is handled.
IPE102 with one group of IP bag of same business through MPE encapsulation, TS encapsulation after, be placed on same period to be sent to radio network.The time sequencing that radio network is arranged according to IPE102 wraps in this group TS among the Time Sliced Burst and to send, and has promptly realized the time slicing transmission.Wherein in the process of MPE encapsulation, IPE102 has write delta t parameter in MPE packet header, and this parameter is used for the correct time that next Time Sliced Burst that prompt terminal equipment should business occurs.DVB-H as shown in Figure 3 carries the protocol stack of IP data, and wherein, the work of IPE102 is mainly in data link layer.Delta t parameter is 12 bits, and unit is 10ms, can represent 0～40950ms altogether.
Said terminal equipment 103 is used to receive message, and the business tine in the consumption message.
Consult shown in Figure 4ly, in the prior art, sudden message service providing system 100 is handled the sudden message business with IPE102 as general business, and its handling process is following:
Step 401, sudden message service providing system inform promptly that to the registration of IPE manager IPE manager multicast ip address is used for sending professional.
Step 402, IPE manager notice IPE, this multicast ip address is used for sending professional.
Step 403,405,409,411 and 415, sudden message service providing system do not produce the message that includes business tine, then send empty IP and wrap to IPE.
Step 404,406,410,412 and 416, IPE receive sky IP bag, carry out MPE encapsulation and TS encapsulation and send to terminal equipment through the DVB network.Be judged as sky IP bag after terminal equipment receives, think that then present sudden message business does not include the message of business tine at present, according to the delta t parameter in MPE packet header, opens receiving system when next time slicing arrives.
Step 407 and 413, sudden message service providing system produce the message that includes business tine, send the IP that includes business tine message and wrap to IPE.
Step 408 and 414, IPE receive the message that includes business tine that the sudden message service providing system is sent, and encapsulation also sends to terminal equipment through the DVB network.Be judged as after terminal equipment receives and include business tine message, resolve and consume this message.
Consult shown in Figure 5ly, the inter-process flow process of IPE is following in the prior art:
To sum up; Prior art is not when having sudden message to send; The sudden message service providing system is sent empty IP and is wrapped to IPE, and IPE is a traffic assignments timeslice and in the DVB Network Transmission, and terminal equipment still need constantly be opened receiving system according to the mode of time slicing and received message this moment; Cause terminal equipment power consumption big like this, the waste of IP network and DVB network bandwidth resources.And, when procotol wrapper IPE does not receive the message from said IP address in the prior art in official hour, can be in error status, can't carry out follow-up reception.In addition, IPE does same treatment to all professional message of sudden message, can't distinguish its priority.

Said sudden message service providing system 600 is used to produce sudden message and sends it to IPE602; When producing sudden message, do not send message to IPE602; Said sudden message service providing system 600 also to said IPE manager 601 registrations, is informed the multicast ip address that is used to send sudden message; The said multicast ip address notice IPE602 that said IPE manager 601 will obtain; Said IPE602; Be used for after receiving the attribute information and the predetermined condition of said message are compared, according to comparative result said message encapsulation back sent to terminal equipment 603 in other professional time slicings, perhaps from the message of said IP address; The said message of delayed delivery; And terminal equipment 603 is known receive time of this message through other professional time slicings, wherein, said IPE allows in official hour, not receive the message from said IP address; Said terminal equipment 603 is used to receive the message after the encapsulation, and the business tine in the consumption message.
Consult shown in Figure 7ly, said sudden message service providing system 600 specifically comprises: generation unit 700, transmitting element 701; Said generation unit 700 is used to produce sudden message; Said transmitting element 701 is used for when producing sudden message, sending said message, when not producing sudden message, does not send message.
Preferable; In said sudden message service providing system 600 during to 601 registrations of said IPE manager; Said transmitting element 701 also sends and is used to send the multicast ip address of sudden message, and the precedence information of the message of sending from this multicast ip address is provided; Perhaps send possible multicast source IP address, and the precedence information of the message of sending from each source IP address is provided.The precedence information of the message that said IPE manager 601 is further sent with the multicast ip address that receives and from this multicast ip address sends to said IPE602; Perhaps, the precedence information of said IPE manager 601 possible multicast source IP address that further will receive and the message sent from each source IP address sends to said IPE602.
Said IPE602 is after the message that receives said sudden message service providing system 600 transmissions; Inspection multicast ip address or multicast source IP address; Confirm that said message is sudden message; And the attribute information and the predetermined condition of said message compared, the attribute information here is meant the content size of the said message that the precedence information of the said message that said IPE602 obtains through said multicast ip address or multicast source IP address and quantity and size through the IP bag obtain; Corresponding; The predetermined condition that compares with said attribute information is meant the specified level of priority and the threshold value of content size; Said IPE602 judges that whether rank and content size that whether the priority of said message be higher than appointment are less than threshold value, if then said message encapsulation back is sent to terminal equipment 603 in other professional time slicings; Otherwise the said message of delayed delivery, and terminal equipment 603 is known receive time of this message through other professional time slicings; When the said message of delayed delivery; IPE602 constructs empty IP bag and its encapsulation back is sent to terminal equipment 603 in other professional time slicing; Indication IPE602 sends the time of the said message after encapsulating in the packet header of said empty IP bag, the said message of terminal equipment 603 after this time receives encapsulation.
Rank and the content size that said IPE602 is higher than appointment in the priority of confirming said message is during less than threshold value, with being transferred to said terminal equipment 603 in said message encapsulation and each time slicing in a period of time.Be illustrated in figure 8 as time slicing mode in such cases, wherein, the content in each time slicing is identical, is the whole of the said message that includes business tine.Like this, terminal equipment all can obtain said message as long as receive any one non sudden messaging service.
Rank or the content size that said IPE602 is lower than appointment in the priority of confirming said message constructed in empty IP bag and each time slicing in a period of time and is transferred to said terminal equipment 603 during greater than threshold value.Be illustrated in figure 9 as time slicing mode in such cases, wherein, the content in each time slicing is identical, is the empty IP bag after the encapsulation.Said IPE602 carries time parameter in the packet header of the MPE bag that encapsulation obtains when the empty IP of encapsulation bag, this time parameter is used to point out said terminal equipment 603 sudden messages the professional correct time that sends and send of being about to.When said IPE602 arrives at the correct time that sends, said message is encapsulated and sends to said terminal equipment 603.To such an extent as to when the message that includes business tine can't have been transmitted greatly, need to distribute a plurality of time slicings in a time slicing.MPE bag in each time slicing all carries delta t parameter, points to next time slicing, sends until the message that includes business tine to finish.Like this, said terminal equipment 603 all can in time receive the prompting that sudden message is about to transmission as long as receive any one non sudden messaging service, and obtains the correct time that message is sent, thereby receives the message that includes business tine.
The condition that above-mentioned IP E handles the message from said IP address that receives be the priority of said message be higher than appointment rank and content size less than threshold value, here this Rule of judgment also can be separately with priority or judge with content size separately; Promptly when priority was higher than the rank of appointment, said IPE sent said message to terminal equipment 603, otherwise the said information and sending of buffer memory is given terminal equipment 603; During less than threshold value, said IPE sends said message to terminal equipment 603 in the content size of said message, otherwise the said information and sending of buffer memory is given terminal equipment 603.
Consult shown in Figure 10ly, said procotol wrapper IPE602 specifically comprises: receiving element 1000, comparing unit 1001, processing unit 1002, transmitting element 1003; Said receiving element 1000 is used to receive the IP address and the corresponding priorities information of sending sudden message, and receives the message from said IP address; Said comparing unit 1001 is used for the attribute information and the predetermined condition of said message are compared; Relatively being meant here compares the content size of said message and priority respectively with the rank of threshold value and appointment; If the content size of said message is higher than the rank of appointment less than threshold value and priority; Then indicate the said message of said processing unit 1002 encapsulation, indicate the message after said transmitting element 1003 will encapsulate to send to terminal equipment; Otherwise, then indicate the said said message of processing unit 1002 buffer memorys and, indicate the message delay after said transmitting element 1003 will encapsulate to send to terminal equipment said message encapsulation.Wherein, Said processing unit 1002 is when the said message of buffer memory, and the empty IP of the no professional content of structure wraps, should sky IP seal dress after; Empty IP bag after will being encapsulated by transmitting element 1003 sends to terminal equipment, and the time of said message is sent in the empty IP bag indication lag after the said encapsulation.Said processing unit 1002 allows in official hour, not receive the message from said IP address.
In the said system of Fig. 6; Solve in the prior art can not be according to the processed message of message the time when being merely; Can not consider that sudden message service providing system 600 do not send message to IPE602 when producing sudden message, procotol wrapper IPE602 allows in official hour, not receive the message from said IP address; But only consider that sudden message service providing system 600 is provided for sending the IP address and the said IP address corresponding priorities information of sudden message to IPE602; IPE602 handles said message according to said precedence information after the message that receives from said IP address.Here, said IPE602 comprises receiving element 1000, comparing unit 1001, processing unit 1002, transmitting element 1003; Wherein compared by the rank of comparing unit 1001 with said priority and appointment, when said priority was higher than the rank of appointment, transmitting element 1002 sent said message to terminal equipment 603, otherwise, the said message of delayed delivery.Said comparing unit 1001 also compares the content size and the threshold value of said message; The content size of rank and said message that said transmitting element 1002 is higher than appointment in said priority is during less than threshold value; Send said message, otherwise, the said message of delayed delivery.
Consult shown in Figure 11ly, said IPE602 is following with the encapsulation of the message that receives and the handling process of sending:
Whether step 1104, the priority of judging said message are higher than rank and the content size of appointment whether less than threshold value, if then carry out the processing of step 1105; Otherwise carry out the processing of step 1107.
Step 1105, with the encapsulation of said message and send to terminal equipment.
Consult shown in Figure 12ly, the handling process of in network, sending sudden message is following:
Step 1200, sudden message service providing system are informed the multicast ip address that is used for messaging service to the registration of IPE manager.
The multicast ip address that is used for messaging service that step 1201, IPE manager will receive is informed IPE.
Step 1202, sudden message service providing system produce sudden message.
Step 1203, sudden message service providing system send to IPE with the sudden message that produces.
Step 1204, IPE encapsulate and send to terminal equipment with the message that receives.
Step 1205, terminal equipment receive the message after the encapsulation, and the business tine in the consumption message.
In step 1203, the sudden message service providing system is not sent message to IPE when not producing sudden message.Preferable, said sudden message service providing system also provides the precedence information of said message when sending message, at this moment, consults shown in Figure 13ly, and the handling process of in network, sending sudden message is following:
Step 1300, sudden message service providing system be to the registration of IPE manager, informs the multicast ip address that is used for messaging service and the precedence information of message.
The multicast ip address that is used for messaging service that step 1301, IPE manager will receive and the precedence information of message are informed IPE.
Step 1302, sudden message service providing system produce sudden message.
Step 1303, sudden message service providing system send to IPE with the sudden message that produces.
After step 1304, IPE received said message, whether whether the priority of judging said message be higher than rank and the content size of appointment less than threshold value.
Rank and the content size that step 1305, IPE are higher than appointment in the priority of confirming said message is during less than threshold value, with sending to terminal equipment after the said message encapsulation; Rank or the content size that is lower than appointment in the priority of confirming said message be during greater than threshold value, constructs empty IP bag and with sending to terminal equipment after its encapsulation, and in the time encapsulation messages of said empty IP bag appointment and send to terminal equipment.
Step 1306, terminal equipment receive the message after the encapsulation and consume the business tine in the message; Perhaps, the time that wraps in appointment according to the empty IP after the encapsulation that receives receives the message after the encapsulation and consumes the business tine in the message.
In another kind of implementation of the present invention; IPE is not when receiving the message of said sudden message operation system transmission; Construct empty IP bag and with sending to terminal equipment after its encapsulation, this implementation can solve the problem that IP network in the prior art, the waste of DVB network bandwidth resources, procotol wrapper IPE can't receive message.Consult shown in Figure 14, IPE encapsulation this moment and to send the handling process of message following:
Step 1400, wait for that next slot time sheet arrives.
Step 1401, judge whether to receive the message that includes business tine, if carry out the processing of step 1403, otherwise carry out the processing of step 1402.
Step 1402, after confirming not receive the message that includes business tine, construct empty IP bag.
Step 1403, the empty IP that will include the message of business tine or not have a professional content seal dress and send to terminal equipment 603.
After the empty IP that IPE will include the message of business tine or not have a professional content seals dress; Time slicing mode when being transferred to terminal equipment 603 has two kinds; Mode one is divided sheet mode for the set time; Consult shown in Figure 15ly, IPE supposition all can be received the message that includes business tine in each time cycle, so give sudden message traffic assignments regular time burst.If in the time cycle, received the message that includes business tine, then encapsulate and send message through the DVB network; If in the period, do not receive the message that includes business tine, then construct an empty IP bag, encapsulation also is sent to the terminal through the DVB network.
Mode two is for dynamic time divides sheet mode, consults shown in Figure 16ly, and IPE does not do any supposition.If do not receive the message that includes business tine in the time cycle, then IPE constructs empty IP bag, and encapsulation is also sent.Sudden message is professional during process of transmitting shares time slicing with other business; If receive the message that includes business tine in the time cycle, then IPE postpones a time cycle transmission with content, and distributes a special time slicing to send message.
Consult shown in Figure 17ly, send sudden message this moment in network handling process is following:
Step 1700, sudden message service providing system are informed the multicast ip address that is used for messaging service to the registration of IPE manager.
The multicast ip address that is used for messaging service that step 1701, IPE manager will receive is informed IPE.
Step 1702, sudden message service providing system produce sudden message.
Step 1703, sudden message service providing system send to IPE with the sudden message that produces.
Step 1704, IPE are when receiving said message, with sending to terminal equipment after the said message encapsulation; When not receiving said message, construct empty IP bag and with sending to terminal equipment after its encapsulation, said empty IP bag indicating terminal equipment receives message when next time slicing arrives.
Step 1705, terminal equipment receive the message after the encapsulation and consume the business tine that comprises in the message; Receive message when perhaps, waiting for that according to the empty IP bag after the encapsulation that receives next time slicing arrives.
Can know that from the foregoing description among the present invention, IPE sends to terminal equipment with sudden message in other professional time slicings, terminal equipment need not to open specially receiving system and receives said message; Perhaps; The said message of said IPE delayed delivery, and terminal equipment is known receive time of this message through other professional time slicings, terminal equipment only needs to open receiving system by this time and receives message; And; IPE does not send message to the terminal when receiving the message that the sudden message service providing system provides, terminal equipment need not to open receiving system and received message this moment, thereby had saved the electric power at terminal; When the sudden message service providing system does not produce sudden message; Do not send any IP bag; The DVB network also need not to transmit data, has practiced thrift the bandwidth resources of IP network and DVB network simultaneously, and; Procotol wrapper IPE allows in official hour, not receive the message from said IP address, follow-uply receives normally; Further, when sending sudden message, can do the processing of different modes to message according to the priority of message.
Obviously, those skilled in the art can carry out various changes and modification to the present invention and not break away from the spirit and scope of the present invention.Like this, belong within the scope of claim of the present invention and equivalent technologies thereof if of the present invention these are revised with modification, then the present invention also is intended to comprise these changes and modification interior.
