Embodiment one, Multimedia Transmission System
The Multimedia Transmission System of embodiment one comprises: net control device 101, broadcast/multi broadcast system 102, unicast system 103 and user terminal 104.
Wherein, user terminal 104 communicates with unicast system 103 with broadcast/multi broadcast system 102, net control device 101 is connected (as shown in Figure 1A) with broadcast/multi broadcast system 102 and unicast system 103, or net control device 101 is positioned at broadcast/multi broadcast system 102 or unicast system 103, between broadcast/multi broadcast system 102 and unicast system 103, connect (as illustrated in figures ib and 1 c).
In Fig. 1, for the purpose of illustrating simply, a user terminal 104 is only shown, in fact, in the Multimedia Transmission System that embodiment one provides, one or more user terminal 104 can be comprised.
In Figure 1A, Figure 1B and Fig. 1 C, user terminal 104 and the line between broadcast/multi broadcast system 102 and unicast system 103 are solid line, it represents that user terminal 104 communicates with unicast system 103 with broadcast/multi broadcast system 102, should not be considered as the restriction to connected mode, user terminal 104 and can adopt wireless connections or wired connection between broadcast/multi broadcast system 102 and unicast system 103, depends on specific implementation.
Particularly, in the Multimedia Transmission System that embodiment one provides,
Net control device 101, for determining that user terminal 104 is for receiving the channel status of the first channel of the multi-medium data of broadcast/multi broadcast system 102 transmission, and user terminal 104 is for receiving the channel status of the second channel of the multi-medium data of unicast system 103 transmission; According to the channel status of the first channel determined and the channel status of second channel, determine:
Sent by broadcast/multi broadcast system 102; Or sent by unicast system 103, or send the multi-medium data of user terminal 104 request by broadcast/multi broadcast system 102 and unicast system 103.
Alternatively, user terminal 104 is for reporting the channel condition information of the channel status being used to indicate the first channel to net control device 101, and be used to indicate the channel condition information of channel status of second channel, net control device 101 is according to the channel condition information being used to indicate the channel status of the first channel received, determine the channel status of the first channel, according to the channel condition information being used to indicate the channel status of second channel received, determine the channel status of second channel.
Alternatively, user terminal 104 reports above-mentioned two kinds of channel condition informations by broadcast/multi broadcast system 102 and/or unicast system 103.
Such as, reported the channel condition information of the channel status being used to indicate the first channel (now broadcast/multi broadcast system 102 should possess up return path by broadcast/multi broadcast system 102, the first channel condition information is reported for user terminal 104), the channel condition information of the channel status being used to indicate second channel is reported by unicast system 103; Or report above-mentioned two kinds of channel condition informations by broadcast/multi broadcast system 102; Or report above-mentioned two kinds of channel condition informations by unicast system 103; Again or, also report above-mentioned two kinds of channel condition informations by other communication systems except broadcast/multi broadcast system 102, unicast system 103, optional reporting schemes has multiple, depends on that actual system is disposed, the tenability etc. of system or user terminal 104.User terminal 104 no matter adopts which kind of reporting schemes, as long as can be provided to report the communication path of above-mentioned two kinds of channel condition informations.
Now, net control device 101 can adopt one of following various ways, determines the channel status of the first channel and the state of second channel:
Channel status determination mode one
The channel condition information being used to indicate the channel status of the first channel that net control device 101 reports according to the user terminal 104 that whether have received, determines the channel status of the first channel; According to the channel condition information being used to indicate the channel status of second channel that the user terminal 104 that whether have received reports, determine the channel status of second channel.
Such as: if net control device 101 receives the channel condition information that user terminal 104 reports the channel status being used to indicate the first channel, then determine that the channel status of the first channel is available, otherwise determine that the channel status of the first channel is unavailable; The channel condition information that user terminal 104 reports the channel status being used to indicate second channel if receive, then determine that the channel status of second channel is available, otherwise determine that the channel status of second channel is unavailable.
Channel status determination mode two
The channel condition information being used to indicate the channel status of the first channel that net control device 101 can report according to the user terminal 104 received, determines the channel status of the first channel; According to the channel condition information being used to indicate the channel status of second channel that user terminal 104 reports, determine the channel status of second channel, wherein, whether channel condition information can be used by indicating channel.
Such as: if the channel condition information being used to indicate the channel status of the first channel that the user terminal 104 that net control device 101 receives reports indicates the channel status of the first channel to be available, then determine that the channel status of the first channel is available; If the channel condition information of what the user terminal received 104 reported the be used to indicate channel status of the first channel indicates the channel status of the first channel to be unavailable, then determine that the channel status of the first channel is unavailable; If the channel status of the channel condition information instruction second channel of what the user terminal received 104 reported the be used to indicate channel status of second channel is available, then determine that the channel status of second channel is available; If the channel status of the channel condition information instruction second channel of what the user terminal received 104 reported the be used to indicate channel status of second channel is unavailable, then determine that the channel status of second channel is unavailable.
Alternatively, channel status is available, comprising: channel idle, channel are not congested, or channel is not marked as forbidding;
Channel status is unavailable, comprising: channel occupancy, channel congestion, or channel is marked as forbidding.
In a communications system, when channel is unoccupied, then channel is idle, now, it has been generally acknowledged that channel is available; When the channel seizure ratio under a community or an equipment exceedes channel seizure ratio threshold value, all channels under this community or this equipment are marked as congested; Sometimes, the attendant of communication system is due to reasons such as Operation and Maintenance (OperationandMaintenance, O & M), and be forbidding by channel tag, when relevant OM reason is eliminated, channel status reverts to available.
Channel status determination mode three
The channel quality determination channel status of net control device 101 basis.Such as:
Determine that the channel status of the first channel is the first available channel the quality whether channel quality of the first channel is better than the first channel;
Determine that the channel status of second channel is the first available channel the quality whether channel quality of second channel is better than second channel;
Determine that the channel status of the first channel is the second available channel the quality whether channel quality of the first channel is better than the first channel;
Determine that the channel status of second channel is the second available channel quality the etc. whether channel quality of second channel is better than second channel.
The mode weighing channel quality has multiple, such as: can according to the Block Error Rate (BLockErrorRate of channel, BLER), bit error rate (BitErrorRate, BER), received signal to noise ratio (SignalNoiseRatio, SIR), received signal strength, or meet the Modulation and Coding Scheme (ModulationandCodingScheme, MCS) that when quality of reception requires, needs adopt, weigh channel quality.
For aforesaid " determining whether the channel quality of the first channel is better than the first available channel quality of the first channel ", such as: the channel quality being weighed channel by the BLER of channel, if the first available channel quality of the first channel is BLER=5%, net control device 101 determines that the BLER of the first channel is 4%, then net control device 101 determines that the channel quality of the first channel is better than the first available channel quality of the first channel;
Or, the channel quality of channel is weighed by the SIR of channel, if the first available channel quality of the first channel is SIR=7dB, net control device 101 determines the SIR=6dB of the first channel, then net control device 101 determines that the first available channel of the first channel ratio first channel is of poor quality;
Again or, by meet the quality of reception require time needs employing MCS weigh channel quality.If the first available channel quality of the first channel is modulation system is QPSK, encoding rate is 2/3, and net control device 101 determine user terminal 104 be correctly decoded first channel need modulation coding mode be at least QPSK, encoding rate is 1/2, then net control device 101 determines that the channel quality of the first channel is more of poor quality than the first available channel of the first channel.
The mode of channel qualities is weighed for other, and determine the mode of channel quality of second channel and above-mentioned citing similar, repeat no longer one by one here.
Alternatively, what net control device 101 can report from user terminal 104 is used to indicate the channel condition information of the channel status of the first channel, obtain the channel quality parameter value of the first channel, and according to the channel quality parameter value of the first channel obtained, determine the channel quality of the first channel;
What report from user terminal 104 is used to indicate the channel condition information of the channel status of second channel, obtains the channel quality parameter value of second channel, and according to the channel quality parameter value of the second channel obtained, determines the channel quality of second channel.
Such as, channel quality parameter is aforesaid BLER, BER, SIR, received signal strength, or meets the MCS etc. that when quality of reception requires, needs adopt.
Net control device 101 determines how to send multi-medium data to user terminal 104 by the various ways comprised as under type:
Judgement mode one
If net control device 101, by channel status determination mode one or two, determines the channel status of the first channel and second channel, then correspondingly, net control device 101 determines that the send mode of multi-medium data comprises:
If the channel status of the first channel is available, then determine to send multi-medium data by broadcast/multi broadcast system 102; Otherwise
If the channel status of second channel is available, then determine to send multi-medium data by unicast system 103.
Judgement mode two
If net control device 101, by channel status determination mode three, determines the channel status of the first channel and second channel, then correspondingly, net control device 101 determines that the send mode of multi-medium data comprises:
If determine, the channel status of the first channel is the first available channel quality that the channel quality of the first channel is better than the first channel, then determine to send multi-medium data by broadcast/multi broadcast system 102; Otherwise
If determine, the channel status of second channel is the first available channel quality that the channel quality of second channel is better than second channel, then net control device 101 is determined to send multi-medium data by unicast system 103; Otherwise, determining that the channel status of the first channel is the second available channel quality that the channel quality of the first channel is better than the first channel, and the channel quality that the channel status of second channel is second channel is when being better than the second available channel quality of the first channel, net control device 101 is determined to send multi-medium data by broadcast/multi broadcast system 102 and unicast system 103;
Wherein, the first available channel quality of the first channel is better than the second available channel quality of the first channel, and the first available channel quality of second channel is better than the second available channel quality of second channel.
Here, by arranging two available channel quality respectively to the first channel and second channel, realizing the grading control of channel quality, when different channels quality, adopting corresponding multi-medium data send mode, realizing more flexible.
A kind of possible implementation is, first available channel quality settings of the first channel is: if the quality of the first channel is the first available channel quality of the first channel or is better than the first available channel quality of the first channel, then the BER of the first channel is lower than a BER threshold value, and message transmission rate is higher, and/or delay variation is less etc.;
Second available channel quality settings of the first channel is: if the quality of the first channel is the second available channel quality of the first channel, then the BER of the first channel is lower than the 2nd BER threshold value, and message transmission rate is lower, and/or delay variation is larger etc.
First available channel quality settings of second channel is: if the quality of second channel is the first available channel quality of second channel or is better than the first available channel quality of second channel, then the BER of second channel is lower than the 3rd BER threshold value, and can message transmission rate higher, and/or delay variation is less etc.;
Second available channel quality of second channel can be set to: if the quality of second channel is the second available channel quality of second channel, then the BER of second channel is lower than the 4th BER threshold value, and message transmission rate is lower, and/or delay variation is larger etc.
Adopt the set-up mode of above-mentioned channel quality, can realize:
When broadcast/multi broadcast system 102 channel quality is higher, preferentially send multi-medium data by broadcast/multi broadcast system 102;
If broadcast/multi broadcast system 102 channel quality is poor, but the channel quality of unicast system 103 is higher, then send multi-medium data by unicast system 103;
If the channel quality of broadcast/multi broadcast system 102 and unicast system 103 is all poor, but still certain bit error rate requirement can be met, then send multi-medium data by broadcast/multi broadcast system 102 and unicast system 103, user terminal 104 can receive the data from two systems, the data received are merged, obtains diversity reception gain.
When the channel quality of the first channel is better than the first available channel quality of the first channel, regardless of the channel quality of second channel, determine that multi-medium data is preferentially sent by broadcast/multi broadcast system 102, achieve and preferentially send multi-medium data by broadcast/multi broadcast system 102.If user terminal 104 number of receiving multimedia data is more simultaneously, and the channel quality of the first channel of user terminal 104 is all greater than the first available channel quality of the first channel, then send multi-medium data by broadcast/multi broadcast system 102, multiple user terminal 104 shares a broadcast/multi broadcast system channel, same multi-medium data can issue multiple user terminal 104 simultaneously, each user terminal 104 is issued respectively with by unicast system 103, each user terminal 104 takies a unicast tunnel and compares, and the data transmission efficiency of broadcast/multi broadcast system 102 is higher.
Alternatively, net control device 101 determine by broadcast/multi broadcast system 102 send user terminal 104 ask multi-medium data, or by broadcast/multi broadcast system 102 and unicast system 103 send user terminal 104 ask multi-medium data after, also comprise:
Net control device 101, according to the channel quality of the first channel determined, determines that broadcast/multi broadcast system 102 sends a MCS of the multi-medium data use that user terminal 104 is asked;
The MCS information being used to indicate the MCS determined is issued broadcast/multi broadcast system 102, and instruction broadcast/multi broadcast system 102 determines the MCS adopted when user terminal 104 sends multi-medium data according to a MCS information;
Net control device 101 determine by unicast system 103 send user terminal 104 ask multi-medium data, or by broadcast/multi broadcast system 102 and unicast system 103 send user terminal 104 ask multi-medium data after, also comprise:
Net control device 101, according to the channel quality of the second channel determined, determines that unicast system 103 sends the 2nd MCS of the multi-medium data use that user terminal 104 is asked; The 2nd MCS information being used to indicate the 2nd MCS determined is issued unicast system 103, and instruction sheet broadcast system 103 determines the MCS adopted when user terminal 104 sends multi-medium data according to the 2nd MCS information.
Adopt this possibility, net control device 101 determines MCS according to channel quality, instruction broadcast/multi broadcast system 102 or unicast system 103, multi-medium data is sent to user terminal 104 according to the MCS determined, avoiding broadcast/multi broadcast system 102, unicast system 103 to adopt inappropriate MCS when sending multi-medium data, reducing the quality of reception of user terminal 104 receiving multimedia data.
Traditional broadcast/multi broadcast system only provides one-way transmission mechanism usually, namely communication link from system to user terminal is provided, and do not have user terminal to arrive the communication link of system, and system is the downlink data quality of reception according to user terminal feedback usually, determine the channel quality of the channel of user terminal downlink data receiving, in traditional broadcast/multi broadcast system, owing to there is not up link, user terminal cannot report self channel quality, thus system cannot obtain the channel quality of user terminal, the mode sending multi-medium data can not be determined neatly according to channel quality, or be only when broadcast/multi broadcast mode is unavailable, mode of unicast is switched to send multi-medium data to each user, cause the waste of Radio Resource.
In embodiment one, owing to there is unicast system 103 and broadcast/multi broadcast system 102 simultaneously, thus user terminal 104 can utilize the up link of unicast system 103 to feed back the channel status from the first channel in broadcast/multi broadcast system 102 to net control device 101, thus net control device 101 accurately can know the channel status of the first channel and the channel status of second channel, the send mode of flexible selection multi-medium data, and when determining to send multi-medium data by broadcast/multi broadcast system 102 to user terminal 104, accurately can determine the MCS adopted, effectively utilize the resource of broadcast/multi broadcast system 102, improve data transmission efficiency.
Judgement mode three
The content of the multi-medium data that net control device 101 is asked according to user terminal 104, and the channel status of the first channel determined and the channel status of second channel, determine the mode sending multi-medium data to user terminal 104.
Such as: the first possible situation: the content of the multi-medium data that user terminal 104 is asked is preferentially by the content (hereinafter referred to as " general character content ") of broadcast/multi broadcast system 102 transmission;
Now, net control device 101 is according to the channel status of the first channel determined and the channel status of second channel, determine by broadcast/multi broadcast system 102, or by broadcast/multi broadcast system 102 and unicast system 103, send multi-medium data to user terminal 104.
The situation that the second is possible: the content of the multi-medium data that user terminal 104 is asked is not preferentially by the content (hereinafter referred to as " personality contents ") of broadcast/multi broadcast system 102 transmission;
Now, net control device 101 is determined to send multi-medium data by unicast system 103 to user terminal 104.
Alternatively, the content meeting the multi-medium data of at least one in following condition is general character content:
Ask the number of the user terminal 104 of this multi-medium data to account for active user's terminal 104 number ratio and be greater than user terminal 104 proportion threshold value (such as: 75%);
The content of this multi-medium data is arranged in the front N name of similar multimedia data contents list, and wherein, N is positive integer (in such as music list, rank is the song of front N name);
User's clicking rate of the content of this multi-medium data exceedes user's clicking rate threshold value.
Each threshold value and N can realize determining according to system above, and can periodically update.
For the situation that the first is possible, net control device 101 can adopt aforesaid judgement mode one or judgement mode two, determines the send mode of multi-medium data.
In traditional broadcast/multi broadcast system, because needs send multi-medium data to multiple user, the channel status that different user terminals is used for the channel of receiving multimedia data is different, such as: channel quality is different, broadcast/multi broadcast system is in order to meet the quality of reception requirement of all user terminals, the data rate of broadcast/multi broadcast is often limited to the poorest user terminal of channel quality, causes like this in broadcast/multi broadcast system, and the resource of the good user terminal of channel quality is wasted.In embodiment one, alternatively, in embodiment one, the channel status of the first channel and the channel status of second channel of each user terminal 104 in multiple user terminals 104 of current request multi-medium data can be considered, determine the mode sending multi-medium data to multiple user terminal 104.
