The present invention reaches the purpose that receiving terminal is saved power consumption by a kind of information carousel method and system are provided.The core of technical solution of the present invention is at system time, take turns and set up and safeguard a kind of incidence relation between the user ID of broadcasting cycle and terminal, make that by this incidence relation system front end and system terminal can be in definite time point transmission user profile relevant with user ID with reception, be that system front end is broadcast the cycle with system time to wheel and got remainder, the system time point of remainder of zero is broadcast the start time point in cycle for wheel, this start time point is added that user ID broadcasts the transmitting time point that remainder that the cycle gets obtains this user profile to wheel, then the user who meets this transmitting time point is carried out issuing after the encryption to the information of its needs with its key at this transmitting time point; System terminal can be broadcast the cycle with system time to wheel and get the surplus current progress that wheel is broadcast that calculates when know that system time and wheel are broadcast the cycle; Again user ID is broadcast the surplus time location of user profile in wheel is broadcast the cycle that calculate of getting of cycle to wheel, more current progress and this time location, if current progress does not arrive this time location, then terminal is waited in epicycle is broadcast the cycle and is received business cipher key information, otherwise just receives business cipher key information in next round is broadcast the cycle.
Below in conjunction with the embodiment of mobile multimedia broadcast system and accompanying drawing technique scheme of the present invention is done and to be explained.
As shown in Figure 1, be the channel frame structure of Mobile Multimedia Broadcasting, each broadcast channel frame frame length 1 second is made up of control logic channel and service logical channels.Wherein, that control logic channel occupancy time slot 0 transmits is a plurality of (1～k) system control information table, and the network information table in the system control information table (first table is a network information table among the figure) is used for the transfer system time, unit be second; Service logical channels is made up of to 39 time slot 1; Form a multiplexed frame by one or more time slot, each multiplexed frame is formed (payload of control logic channel is made up of a plurality of system control information tables) by frame head and payload, the payload of service logical channels is made up of a plurality of multiplexed sub frames, and each subframe is made up of video-frequency band, audio section and data segment.
In Mobile Multimedia Broadcasting, key is divided into user key, business cipher key and program key.Wherein, user key be used for the sign related one by one, be rooted in terminal; Business cipher key is by after encrypting with each user key, wheel is broadcast to terminal, so the business cipher key behind each user encryption is different, and then terminal is selected the secure service key of oneself in the many business cipher keys that need trailing wheel to broadcast when receiving business cipher key.If in Mobile Multimedia Broadcasting single carrier 8MHz system, adopt two-phase PSK (BPSK, Binary Phase Shift Keying) modulation system, multiplexed sub frame data segment wheel with a time slot is broadcast business cipher key, wherein business cipher key length is 32, the total system business is with regard to a business cipher key, and per second will send 270 customer service key informations so.
If it is 1800 seconds (promptly 30 minutes) that the business cipher key of system configuration wheel is broadcast the cycle, take turns the zero-time of broadcasting business cipher key so and be the least bit and integral point (... 8:00,8:30,9:00,9:30,10:00,10:30......); If a user ID is 123456789, this user profile was orientated as in the time that wheel is broadcast the cycle so: 123456789%1800=189 (=3 minutes and 9 seconds), promptly system front end sends this user's business cipher key when wheel is broadcast start time point and added 3 minutes and 9 seconds.
If mobile multimedia broadcast receiving terminal receives the network service, the system time that from network information table, obtains 9: 1: 15, so in epicycle is broadcast the cycle, the business cipher key time that front end sends this user is 9: 3: 9 (promptly take turns the zero-time 9:00 that broadcasts business cipher key and add 3 minutes and 9 seconds), terminal only need be broadcast the cycle in epicycle and wait for 1 minute and 54 seconds again, just can receive the business cipher key information that this time slot transmits, thereby obtain the business cipher key of self; If the system time that obtains from network information table is 9: 20: 15, obviously surpassed 9: 3: 9 the transmitting time that epicycle is broadcast the cycle, front end business cipher key time of sending this user will be taken turns 9: 33: 9 of the cycle of broadcasting (be the next round of business cipher key broadcast zero-time 9:30 add 3 minutes and 9 seconds) for next so, terminal need wait by the time should the time, receive the business cipher key information that this time slot transmits again, thereby obtain the business cipher key of self.
Be illustrated in figure 2 as the transmission handling process of mobile multimedia broadcast system front end of the present invention to business cipher key, this flow process may further comprise the steps:
210: system front end is broadcast the cycle according to the wheel of system time and system configuration, obtains the zero-time that wheel is broadcast the cycle; Be that system time is broadcast the cycle to wheel and got remainder, the system time point of remainder of zero (is the absolute time of unit with the second) is broadcast the start time point in cycle for wheel;
220: user ID is broadcast the cycle to wheel get remainder and obtain the time location of this user profile in wheel is broadcast the cycle, determine the transmitting time point of each user profile in wheel is broadcast the cycle by this start time point and this time are located addition;
230: name a person for a particular job in this transmitting time and to satisfy the user of this time point, respectively business cipher key is encrypted with its user key, and be handed down to terminal by network;
240: handle the customer service key of next second, judge that epicycle broadcasts the cycle and whether finish, carry out, promptly enter next round and broadcast the cycle if return step 220; Then returning step 230 if not carries out.
As shown in Figure 3, be the reception handling process of mobile multimedia broadcast system terminal of the present invention to business cipher key, this flow process comprises step:
310: terminal receives control channel information, current system time of acquisition and wheel are broadcast the cycle from network information table, calculating wheel broadcasts the cycle start time point and broadcasts progress when front-wheel, wherein broadcast progress when front-wheel and equal current system time and wheel is broadcast the cycle get remainder, remainder is that zero system time is taken turns exactly and broadcast start time point;
About system time, a kind of mode is to send to terminal accurately by system front end in each broadcast frame; Another kind of mode then is that terminal self provides system time accurately; Broadcast the cycle about wheel, a kind of mode is to send wheel by system front end by network information table to broadcast cycle numerical value to receiving terminal, and a kind of is that unified definite system of operator wheel is broadcast the cycle.
320: user ID is broadcast the cycle to wheel get remainder and obtain the time location of this customer service key in wheel is broadcast the cycle;
330: will work as front-wheel and broadcast progress and compare time, and judge whether the time of reception point reception business cipher key in epicycle is broadcast the cycle, if with regard to execution in step 340 with this location; Execution in step 350 then if not;
340: wait for (not receiving the aerial signal state) that time of reception is put the back and received business cipher key, process ends in epicycle is broadcast the cycle;
This time location and start time point addition are obtained obtaining the time of reception point of business cipher key;
It is for example above-mentioned if the system time that obtains from network information table is 9: 1: 15, then work as front-wheel and broadcast progress=(9 * 3600+60+15)/1800%=75, and the time location=189 of business cipher key in wheel is broadcast the cycle, the two is compared, learn also to differ from time of reception point (9: 3: 9) the reception information that 114 seconds (1 minute and 54 seconds) can be in epicycle be broadcast the cycle.
350: wait for (not receiving the aerial signal state), broadcast the time of reception in cycle in next round and put back reception business cipher key, process ends.
Start time point and wheel are broadcast the cycle addition obtain nearest start time point, this nearest start time point and the location addition of above-mentioned time are just obtained the time of reception point that next round is broadcast the cycle.
It is for example above-mentioned if the system time that obtains from network information table is 9: 20: 15, then broadcast progress=(9 * 3600+20 * 60+15)/1800%=1215 when front-wheel, and the time location=189 of business cipher key in wheel is broadcast the cycle, the two is compared (be next round broadcast zero-time 9:30 add 3 minutes and 9 seconds) the reception information of learning the time of reception point that needs in lower whorl is broadcast the cycle 9: 33: 9.
Should see, in above-mentioned steps 330, compare judgement, be not the progress of broadcasting when front-wheel must be compared with this time location just can judge, as previously mentioned, also wheel can be broadcast the time location addition in wheel is broadcast the cycle of nearest start time point and this customer service key, obtain epicycle and broadcast the time of reception point of business cipher key in the cycle, then this time of reception point is compared with current system time, if current system time does not also arrive this time of reception point, judge that then the time of reception point in epicycle is broadcast the cycle receives business cipher key, promptly execution in step 340; If current system time has surpassed this time of reception point, judge that then the time of reception point in next round is broadcast the cycle receives business cipher key, promptly execution in step 350.
What exemplify in the foregoing description is Mobile Multimedia Broadcasting single-carrier system situation, and in the radio broadcasting field, can send wheel by a plurality of carrier waves (perhaps frequency) mode and broadcast information, a kind of mode is that each user profile concentrates on some carrier waves wheel and sows and send out, another kind of mode is that each user profile is sowed at the different carrier wheel and sent out, and promptly issues at related carrier wave.
If each information concentrates on carrier wave wheel and sows and send out, related by user ID with carrier wave, front end sends particular user information place carrier wave and can obtain by the remainder of terminal user identification to carrier number, and receiving terminal is also by calculating the carrier wave that this remainder obtains the self information place.
If each user profile issues at related carrier wave, then on related carrier wave, broadcast the cycle and user ID calculates the time point that the information wheel is broadcast by computing system time, wheel.
Network can be unified numbering to carrier wave.
In the radio broadcasting field, can also send wheel by multichannel and broadcast information, broadcast information as sending wheel by a plurality of channels in the radio broadcasting, a kind of mode is that the information of certain user's association concentrates on a passage transmission, and a kind of mode is that certain user profile sends at the passage of association.
If user profile concentrates on a passage and issues, related by user ID with passage, front end sends particular user information place passage and can obtain by the remainder of terminal user identification to port number, and receiving terminal is also by calculating the passage that this remainder obtains the self information place.
If each user profile issues at association channel, then on association channel, by the computing system time, wheel is broadcast the cycle and user ID calculates.
Network can be unified numbering to passage.
