[017。 [017. 比如,通过广播/多播系统102上报用于指示第一信道的信道状态的信道状态信息(此时广播/多播系统102应具备上行回传信道,供用户终端104上报第一信道状态信息),通过单播系统103上报用于指示第二信道的信道状态的信道状态信息;或通过广播/多播系统102上报上述两种信道状态信息;或通过单播系统103上报上述两种信道状态信息;再或者,还可通过除了广播/多播系统102、单播系统103之外的其他通信系统上报上述两种信道状态信息,可选的上报方式有多种,取决于实际的系统部署、系统或用户终端104的支持能力等。 For example, reporting of channel state indication for the first channel of the channel state information via the broadcast / multicast system 102 (this time broadcast / multicast system 102 should have uplink backhaul channel for the user terminal 104 reports the first channel state information) , unicast system reporting channel state information for the channel state indicates that the second channel 103; or reporting both the channel state information by a broadcast / multicast system 102; or unicast system 103 reports both the channel state information ; or, in addition also through broadcast / multicast system 102, a unicast communication system other than the system 103 reports both the channel state information, a variety of reporting alternative embodiment, depending on the actual system deployment, system or the ability to support a user terminal 104. 不管采用哪种上报方式,只要能够提供用户终端104上报上述两种信道状态信息的通信通路即可。 Either reporting way, as long as it provides the user terminal 104 reports the channel state information of the two communication paths can.

[0172] 此时,网络控制设备101可采用下列多种方式之一,确定第一信道的信道状态和第二信道的状态: [0172] In this case, 101 may be employed in various ways one of the network control apparatus, determines a first channel and a second channel state of the channel state:

[0173] 信道状态确定方式一 [0173] a channel state determination mode

[0174] 网络控制设备101根据是否收到了的用户终端104上报的用于指示第一信道的信道状态的信道状态信息,确定第一信道的信道状态;根据是否收到了的用户终端104上报的用于指示第二信道的信道状态的信道状态信息,确定第二信道的信道状态。 [0174] network control apparatus 101 the channel state information according to a channel state is received in the user terminal 104 reports the indication for the first channel, determining a first channel of the channel state; reported according to whether received user terminal 104 with channel state information indicating the channel state of the second channel, determining a channel state of the second channel.

[01巧]比如;若网络控制设备101收到用户终端104上报用于指示第一信道的信道状态的信道状态信息,则确定第一信道的信道状态为可用,否则确定第一信道的信道状态为不可用;若收到用户终端104上报用于指示第二信道的信道状态的信道状态信息,则确定第二信道的信道状态为可用,否则确定第二信道的信道状态为不可用。 [01 Qiao] For example; if the network control apparatus 101 receives the user terminal 104 reports the channel state indication for the first channel of the channel state information, determining a channel state of the first channel is available, otherwise, determining a channel state of the first channel unavailable; If the received user terminal 104 reports the channel state indicates that the second channel is a channel state information, it is determined that the channel state of the second channel is available, otherwise, determining a channel state of the second channel is unavailable.

[0176] 信道状态确定方式二 [0176] Channel state determining second approach

[0177] 网络控制设备101可根据收到的用户终端104上报的用于指示第一信道的信道状态的信道状态信息,确定第一信道的信道状态;根据用户终端104上报的用于指示第二信道的信道状态的信道状态信息,确定第二信道的信道状态,其中,信道状态信息可指示信道是否可用。 [0177] Channel state information may be reported by the network control device 101 according to a user terminal 104 receives a first channel for indicating a channel state, a first channel to determine channel state; reported by the user terminal 104 for instructing a second the channel state information of the channel status channel, determining a channel state of the second channel, wherein the channel state information may indicate whether a channel is available.

[0178] 比如;若网络控制设备101收到的用户终端104上报的用于指示第一信道的信道状态的信道状态信息指示第一信道的信道状态为可用,则确定第一信道的信道状态为可用;若收到的用户终端104上报的用于指示第一信道的信道状态的信道状态信息指示第一信道的信道状态为不可用,则确定第一信道的信道状态为不可用;若收到的用户终端104 上报的用于指示第二信道的信道状态的信道状态信息指示第二信道的信道状态为可用,贝U 确定第二信道的信道状态为可用;若收到的用户终端104上报的用于指示第二信道的信道状态的信道状态信息指示第二信道的信道状态为不可用,则确定第二信道的信道状态为不可用。 [0178] for example; the channel state of the channel state information indicates a first channel for indicating a first channel of the channel state of the user terminal 104. If the network control apparatus 101 receives the report is available, it is determined that the channel state of the first channel is available; the channel state of the user terminal 104 if the received report letter to indicate a first channel of the channel status channel state information indicates the first channel is unavailable, it is determined that the channel state of the first channel is unavailable; if received the user terminal 104 reports the channel state for the channel state indicates that the second channel information indicates a second channel channel state is available, shellfish U determining a second channel channel state is available; user terminal 104 if the received reported channel status channel status indicating channel state for the second channel information indicates the second channel is unavailable, it is determined that the channel state of the second channel is unavailable.

[0179] 可选地,信道状态为可用,包括:信道空闲、信道未拥塞,或信道未被标记为禁用; [0179] Alternatively, the channel state is available, comprising: idle channel, the channel is not congested, or a channel not marked as disabled;

[0180] 信道状态不可用,包括:信道占用、信道拥塞,或信道被标记为禁用。 [0180] channel status is not available, comprising: channel occupancy, channel congestion, or the channel is marked as disabled.

[0181] 在通信系统中,当信道未被占用时,则信道为空闲,此时,通常认为信道是可用的;当一个小区或一个设备下的信道占用率超过信道占用率阔值时,该小区或该设备下的所有信道被标记为拥塞;有时,通信系统的维护人员由于操作维护的perationand Maintenance, 0&M)等原因,将信道标记为禁用,当相关的OM原因消除时,信道状态恢复为可用。 [0181] In a communication system, when the channel is unoccupied, the channel is idle, then, is generally considered channels are available; when the channel occupancy in a cell or a device over the channel occupancy width value, the cell or all channels in the device is marked as congested; sometimes, maintenance personnel communication system due to the operation perationand maintenance maintenance, 0 & M) and other reasons, the channel is marked as disabled, when the associated OM eliminating the cause, the channel status returns to available.

[0182] 信道状态确定方式H [0182] Channel state determination mode H

[0183] 网络控制设备101根据的信道质量确定信道状态。 [0183] channel quality according to network control apparatus 101 determines the channel state. 比如: such as:

[0184] 确定第一信道的信道状态为第一信道的信道质量是否优于第一信道的第一可用信道质量; If [0184] determining a first channel of the first channel state of channel is better than the channel quality of the first channel quality of a first available channel;

[0185] 确定第二信道的信道状态为第二信道的信道质量是否优于第二信道的第一可用信道质量; Whether a channel quality [0185] determining a second channel for the channel state is better than the second channel of the second channel quality of the first channel is available;

[0186] 确定第一信道的信道状态为第一信道的信道质量是否优于第一信道的第二可用信道质量; If [0186] determining a first channel of the first channel state of channel is better than the channel quality of the first channel quality of the second channel is available;

[0187] 确定第二信道的信道状态为第二信道的信道质量是否优于第二信道的第二可用信道质量等。 Whether a channel quality [0187] determining a second channel, a channel state to a second channel of the second channel is better than the second available channel quality.

[0188] 衡量信道质量的方式有多种,比如:可根据信道的误块率度LockErrorRate, BLER)、误比特率度itErrorRate,邸时、接收信噪比(Si即alNoiseRatio,SIR)、接收信号强度,或者满足接收质量要求时需要采用的调制编码方案(Mo化IationandCoding Scheme,MCS),来衡量信道质量。 [0188] There are several ways to measure the channel quality, such as: can LockErrorRate, BLER block error rate as measured according to the channel), the bit error rate of itErrorRate, when Di, received SNR (Si i.e. alNoiseRatio, SIR), the received signal strength, or to meet the modulation and coding scheme (Mo of IationandCoding scheme, MCS) to be utilized upon reception quality, channel quality measure.

[0189]W前述的"确定第一信道的信道质量是否优于第一信道的第一可用信道质量"为例,比如:通过信道的BLER来衡量信道的信道质量,若第一信道的第一可用信道质量为BLm? = 5%,网络控制设备101确定第一信道的BLm?为4%,则网络控制设备101确定第一信道的信道质量优于第一信道的第一可用信道质量; [0189] W aforementioned "determining a first channel, the channel quality is better than the first channel of the first available channel quality" as an example, such as: a channel quality measured by the channel by BLER channel, the first if the first channel available channel quality BLm = 5%, network control apparatus 101 determines BLm first channel is 4%, the network control apparatus 101 determines a first available channel quality of a channel quality of the first channel is better than the first channel??;

[0190] 或者,通过信道的SIR来衡量信道的信道质量,若第一信道的第一可用信道质量为SIR= 7地,网络控制设备101确定第一信道的SIR= 6地,则网络控制设备101确定第一信道比第一信道的第一可用信道质量差; [0190] Alternatively, to measure the channel by SIR channel, channel quality, if the first available channel quality of the first channel is SIR = 7, the network control apparatus 101 determines a first channel SIR = 6, the network control apparatus 101 determining a first channel of the first channel than the channel of the first available channel quality is poor;

[01W] 再或者,通过满足接收质量要求时需要采用的MCS来衡量信道质量。 [01W] Or, to measure the channel quality MCS requires, by satisfying the reception quality requirements. 若第一信道的第一可用信道质量为调制方式为QPSK,编码率为2/3,而网络控制设备101确定用户终端104正确解码第一信道需要的调制编码方式至少为QPSK,编码率为1/2,则网络控制设备101确定第一信道的信道质量比第一信道的第一可用信道质量差。 When the first available channel quality of the first channel modulation scheme QPSK, coding rate is 2/3, the network control apparatus 101 determines that the user terminal 104 correctly decodes the first channel modulation and coding scheme requires at least QPSK, coding rate is 1 / 2, the network control apparatus 101 determines the channel quality of the first channel is first available channel is worse than quality of the first channel.

[0192] 对于其他衡量信道质量的方式,W及确定第二信道的信道质量的方式与上述举例类似,送里不再一一赏述。 [0192] For another way of measuring channel quality, W, and determining a second channel of the channel quality similar manner to the above-described example, in not going to send said reward.

[0193] 可选地,网络控制设备101可从用户终端104上报的用于指示第一信道的信道状态的信道状态信息中,获取第一信道的信道质量参数值,并根据获取的第一信道的信道质量参数值,确定第一信道的信道质量; [0193] Alternatively, the channel state information of the network control apparatus 101 may be reported from the user terminal 104 for instructing a first channel of the channel state, obtaining a first channel a channel quality parameter value, and in accordance with a first channel acquisition the channel quality parameter value, determining a channel quality of a first channel;

[0194] 从用户终端104上报的用于指示第二信道的信道状态的信道状态信息中,获取第二信道的信道质量参数值,并根据获取的第二信道的信道质量参数值,确定第二信道的信道质量。 [0194] from the channel state of the channel state of the user terminal 104 is reported for indicating a second channel information, obtain a second channel of the channel quality parameter value and quality parameter values ​​of a channel according to a second channel acquired, determining the second channel quality of the channel.

[0195] 比如,信道质量参数为前述的BL邸、邸R、SIR、接收信号强度,或者满足接收质量要求时需要采用的MCS等。 [0195] For example, as the channel quality parameter of BL Di, Di R, SIR, used when required received signal strength or received quality to meet the requirements such as MCS.

[0213] 若广播/多播系统102信道质量较差,但单播系统103的信道质量较高,则通过单播系统103发送多媒体数据; [0213] When the broadcast / multicast channel quality is poor 102 system, but the higher the unicast channel quality system 103, the multimedia data via a unicast transmission system 103;

[0214] 若广播/多播系统102和单播系统103的信道质量均较差,但仍能满足一定的误比特率要求,则通过广播/多播系统102和单播系统103发送多媒体数据,用户终端104可接收来自两个系统的数据,将接收的数据合并,获得分集接收增益。 [0214] When the broadcast / multicast system 102 and the unicast channel system 103 are poor quality, but still meet certain bit error rate requirement, the broadcast / multicast and unicast systems 102 transmit multimedia data through the system 103, the user terminal 104 can receive data from two systems, the combined received data, to obtain diversity reception gain.

[0215] 在第一信道的信道质量优于第一信道的第一可用信道质量时,无论第二信道的信道质量如何,确定多媒体数据优先通过广播/多播系统102发送,实现了优先通过广播/多播系统102发送多媒体数据。 [0215] When the first available channel quality a channel quality of the first channel is better than the first channel, regardless of the channel quality of the second channel, to determine the multimedia data priority by sending a broadcast / multicast system 102, to achieve priority over the broadcast / multicast system 102 transmits the multimedia data. 若同时接收多媒体数据的用户终端104数较多,且用户终端104的第一信道的信道质量都大于第一信道的第一可用信道质量,则通过广播/多播系统102发送多媒体数据,多个用户终端104共用一个广播/多播系统信道,同一多媒体数据可同时发给多个用户终端104,与通过单播系统103分别发给每一个用户终端104,每一个用户终端104占用一个单播信道相比,广播/多播系统102的数据传输效率较高。 If the number of user terminals 104 simultaneously receive more multimedia data, and the channel quality of the first channel of user terminal 104 are larger than the first available channel quality of the first channel 102 through the transmitting multimedia broadcast / multicast data system, a plurality of the user terminal 104 share a broadcast / multicast channel system, the same data simultaneously to a plurality of multimedia user terminals 104, 103 and unicast systems are distributed to each user terminal 104, each user terminal 104 occupies a unicast channel compared broadcast / multicast system 102 of the higher data transmission efficiency.

[0216] 可选地,在网络控制设备101确定通过广播/多播系统102发送用户终端104请求的多媒体数据,或通过广播/多播系统102和单播系统103发送用户终端104请求的多媒体数据之后,还包括: [0216] Alternatively, the network control apparatus 101 determines that the multimedia data by the user terminal 104 transmits a broadcast / multicast request system 102, or 103 sends a request through the user terminal 104 a broadcast / multicast and unicast systems 102 multimedia data system after further comprising:

[0217]网络控制设备101根据确定的第一信道的信道质量,确定广播/多播系统102发送用户终端104请求的多媒体数据使用的第一MCS; [0217] network control apparatus 101 according to the channel quality determination of the first channel is determined broadcast / multicast MCS system 102 transmits a first user terminal 104 requests the multimedia data used;

[0218] 将用于指示确定的第一MCS的第一MCS信息发给广播/多播系统102,指示广播/ 多播系统102根据第一MCS信息确定向用户终端104发送多媒体数据时采用的MCS; [0218] The first MCS for a first information indicating the determined MCS send broadcast / multicast system 102, indicating broadcast / multicast system 102 uses when transmitting multimedia data to the user terminal 104 in accordance with a first MCS is MCS information determined ;

[0219] 在网络控制设备101确定通过单播系统103发送用户终端104请求的多媒体数据,或通过广播/多播系统102和单播系统103发送用户终端104请求的多媒体数据之后, 还包括: [0219] In the network control apparatus 101 determines a unicast system 103 then transmits the multimedia data requested by the user terminal 104 or user terminal 104 transmits the multimedia data requested by the broadcast / multicast and unicast system 102 via system 103, further comprising:

[0220] 网络控制设备101根据确定的第二信道的信道质量,确定单播系统103发送用户终端104请求的多媒体数据使用的第二MCS;将用于指示确定的第二MCS的第二MCS信息发给单播系统103,指示单播系统103根据第二MCS信息确定向用户终端104发送多媒体数据时采用的MCS。 [0220] network control apparatus 101 according to the channel quality determination of the second channel, determining a second MCS unicast transmission system 103 of the user terminal 104 requests the multimedia data to be used; for the second indicating the determined second MCS MCS information unicast distributed system 103, system 103 indicates unicast transmission MCS used when the multimedia data to the user terminal 104 in accordance with a second MCS information is determined.

[0221] 采用该可选方案,网络控制设备101根据信道质量确定MCS,指示广播/多播系统102或单播系统103,按照确定的MCS向用户终端104发送多媒体数据,避免广播/多播系统102、单播系统103在发送多媒体数据时采用不恰当的MCS,降低用户终端104接收多媒体数据的接收质量。 [0221] With this alternative, the network control apparatus 101 is determined according to channel quality the MCS, indicating broadcast / multicast system 102 or unicast system 103, transmits the multimedia data to the user terminal 104 in accordance with the determination of the MCS, to avoid broadcast / multicast system 102, system 103 uses the unicast inappropriate MCS when transmitting multimedia data, the reception quality falls user terminal 104 receives the multimedia data.

[0222] 传统的广播/多播系统通常仅提供单向传输机制,即提供从系统到用户终端的通信链路,而没有用户终端到系统的通信链路,而通常系统是根据用户终端反馈的下行数据接收质量,来确定用户终端接收下行数据的信道的信道质量,在传统的广播/多播系统中, 由于不存在上行链路,用户终端无法上报自身的信道质量,因而系统无法获取用户终端的信道质量,不能灵活地根据信道质量确定发送多媒体数据的方式,或者仅是在广播/多播方式不可用时,切换为单播方式向每个用户发送多媒体数据,造成无线资源的浪费。 [0222] Traditional broadcast / multicast systems typically only provide one-way transmission mechanism that provides a communication link from the system to the user terminal, the user terminal without the communication link to the system, the system is usually based on the user feedback terminal downlink data reception quality, determines the channel quality of the user terminal receives the downlink data channel, in the conventional broadcast / multicast system, since the uplink does not exist, the user terminal can not report the channel quality of its own, thus the system can not obtain a user terminal channel quality, can not be flexibly determined transmitting multimedia data according to channel quality mode, or only when a broadcast / multicast mode is not available, switching to unicast transmitting multimedia data to every user, causing waste of radio resources.

[0223] 实施例一中,由于同时存在单播系统103和广播/多播系统102,因而用户终端104可W利用单播系统103的上行链路向网络控制设备101反馈自身在广播/多播系统102 中的第一信道的信道状态,从而网络控制设备101能够准确获知第一信道的信道状态和第二信道的信道状态,灵活选择多媒体数据的发送方式,并在确定通过广播/多播系统102向用户终端104发送多媒体数据时,可准确确定采用的MCS,有效利用广播/多播系统102的资源,提高数据传输效率。 [0223] In one embodiment embodiment, the presence system 103 and unicast simultaneously broadcast / multicast system 102, so that the user terminal 104 may utilize W unicast uplink feedback system 103 itself to the network control apparatus 101 broadcasting / multicasting a channel state of the system 102 of the first channel so that the network control device 101 can accurately know the channel state of the channel state of the first channel and a second channel, the flexibility to choose the transmission mode of the multimedia data, and is determined by the broadcast / multicast system when transmitting multimedia data 102 to a user terminal 104, it may be used to accurately determine the MCS, efficient use of resources broadcast / multicast system 102, improving data transmission efficiency.

[0224] 判决方式H [0224] decision mode H

[0225] 网络控制设备101根据用户终端104请求的多媒体数据的内容,W及确定的第一信道的信道状态和第二信道的信道状态,确定向用户终端104发送多媒体数据的方式。 [0225] network control apparatus 101 according to the content of the user terminal 104 requests the multimedia data, the channel state, and determining a channel state W to the first channel and the second channel, determining the way of transmitting multimedia data to the user terminal 104.

[022引比如;第一种可能的情况;用户终端104请求的多媒体数据的内容为优先通过广播/多播系统102发送的内容(W下简称为"共性内容"); [022 such as lead; a first possible; user terminal 104 requests the content of multimedia data as a priority by broadcast / multicast transmission of the content system 102 (W hereinafter referred to as "common content");

[0227]此时,网络控制设备101根据确定的第一信道的信道状态和第二信道的信道状态,确定通过广播/多播系统102,还是通过广播/多播系统102和单播系统103,向用户终端104发送多媒体数据。 [0227] In this case, the network control apparatus 101 according to the channel state of the channel state determining a first channel and a second channel, is determined by the broadcast / multicast system 102, or through a broadcast / multicast system 102 and the unicast system 103, transmitting multimedia data to the user terminal 104.

[022引第二种可能的情况;用户终端104请求的多媒体数据的内容不是优先通过广播/ 多播系统102发送的内容(W下简称为"个性内容"); [022 cited a second possible situation; content requested by the user terminal 104 is not a priority multimedia data by broadcast / multicast content transmission system 102 (W hereinafter referred to as "personalized content");

[0229] 此时,网络控制设备101确定通过单播系统103向用户终端104发送多媒体数据。 [0229] At this time, the control device 101 determines the network transmits multimedia data to the user terminal 104 via a unicast system 103.

[0233] 该多媒体数据的内容的用户点击率超过用户点击率阔值。 [0233] User content CTR of the multimedia user data exceeds the width CTR value.

[0234]W上各阔值和N可根据系统实现确定,并可周期性更新。 [0234] each of the width W and the value N may be determined according to system implementation, and may be updated periodically.

[0235] 对于第一种可能的情况,网络控制设备101可采用前述的判决方式一或判决方式二,确定多媒体数据的发送方式。 [0235] The first possible case, the network control mode decision apparatus 101 may employ the above-described embodiment a decision or two, determines the transmission mode of the multimedia data.

[0236] 在传统的广播/多播系统中,由于需要向多个用户发送多媒体数据,不同用户终端用于接收多媒体数据的信道的信道状态不同,比如:信道质量不同,广播/多播系统为了满足所有用户终端的接收质量要求,广播/多播的数据速率往往受限于信道质量最差的用户终端,送样导致在广播/多播系统中,信道质量较好的用户终端的资源被浪费。 Different channel conditions [0236] In the conventional broadcast / multicast system, since the need to send multimedia data to a plurality of users, different user terminals for channel receiving multimedia data, such as: different channel quality, broadcast / multicast system for meet all user terminals receiving quality requirements, broadcast / multicast data rate is often limited to a worst channel quality of the user terminal, sending samples resulting in a broadcast / multicast system, a better channel quality resources of the user terminal is wasted . 实施例一中,可选地,在实施例一中,可综合考虑当前请求多媒体数据的多个用户终端104中每一个用户终端104的第一信道的信道状态和第二信道的信道状态,来确定向多个用户终端104 发送多媒体数据的方式。 Example one in the embodiment, alternatively, in the first embodiment may be considered a plurality of user terminals 104 currently requested multimedia data channel state of each user of the first channel terminal 104 of the channel state and a second channel to determining a manner of transmitting multimedia data to a plurality of user terminal 104.
