一种动态频j普分配的方法和系统 Method of Dynamic Frequency distribution P j and systems

技术领域 FIELD

本发明涉及无线通信领域频语分配技术,特别是指一种动态频镨分配的方法和系统。 The present invention relates to the field of wireless communications language frequency distribution technology, particularly to a method and system for dynamic frequency allocation praseodymium.

背景技术 Background technique

无线电通信频镨是一种宝贵的、有限的资源,目前由国家统一分配、授权使用。 Radio frequency praseodymium is a valuable, limited resources, the current allocation of national unity by unauthorized use. 一个频段一般仅供一个无线通信系统独立使用,不同的无线通信系统使用不同的频段,互不千扰。 Usually only one frequency band independently of a radio communication system using different wireless communication systems using different frequency bands, one thousand no mutual interference.

但是,随着无线通信的迅速发展,特别是由于近来基于频谱的服务和设备显著增加,人们对频镨资源的需求越来越大,频镨资源日趋匮乏。 However, with the rapid development of wireless communication, especially due to the recent spectrum of services and equipment based on a significant increase in demand for resources is increasing frequency praseodymium, praseodymium frequency resources become increasingly scarce. 这种预先分配、授权使用的静态频语管理方式,使某些频段承载的业务量很大,而另一些频段却在大部分时间内没有用户使用,白白浪费了频谦资源。 This pre-assigned, static frequency management authorized to use language to make some great bands bearer traffic, and some bands but not user to use most of the time wasted frequency modest resources. 无线电系统的通信量是随着时间和地点不断变化的,然而当前大多数无线电系统的频镨都是根据"峰值时刻"的通信量来分配, 因此在非"峰值时刻"的频i普资源都未能得到充分利用,造成浪费。 Amount of radio communication systems are changing with time and place, but most of the current radio frequency praseodymium system are allocated according to traffic "peak time", and thus not "peak time" P-frequency resources i underutilized, resulting in waste. 所谓"峰值时刻"是指特定时间段内,通信量最大的时刻。 The so-called "peak time" refers to the maximum time a certain time period, traffic.

针对日益严重的无线频i普资源"短缺"与"浪费"问题,可以通过基于无线电系统的技术创新来解决,以达到频语资源的高效利用,从而出现了动态频谱分配技术用于解决这个矛盾。 For the growing problem of wireless frequency resources i P "shortage" and "waste" problem can be solved by technological innovation based radio system, in order to achieve efficient use of frequency resources of language, which appeared in this conflict dynamic spectrum allocation technique for solving . 基于认知无线电的频镨共享概念由J.Mitola首次提出,这一技术使得在任何时间、任何地点分配任意频谱成为可能。 Sharing the concept of frequency praseodymium based on cognitive radio was first proposed by J.Mitola, the technology allows at any time, any place any allocation of spectrum possible. 在这种发展趋势下,终端和网络设备需要具备可重配置能力,即能够支持工作频率及技术参数的转换从而可以使用比以往固定分配频点更多的频率资源。 In this trend, the terminal equipment and the network requires reconfigurability, i.e., capable of supporting the frequency switching operation and technical parameters can be used in a conventional fixed allocation of frequency resources than more frequency. '重配置技术还能够支持通信模式的改变或共存,通信终端可以灵活的才艮据无线环境更改自身的配置,以达到完成通信功能的目的。 'Reconfiguration can also support or coexistence of communication modes change, the communication terminal can flexibly according to the radio environment changes only Gen own configuration, in order to achieve complete communication function.

5可以假定,具备了重配置功能的通信实体,能够灵活的调整系统的工作频点,而不受调制方式的限制。 5 may be assumed, provided the function of the communication entity reconfiguration, the flexibility of the working frequency adjustment system, without being limited by the modulation scheme. 这是通过对现有系统射频部分的升级或设计全新的通信系统而实现的。 This is achieved to design new or upgrade the existing system of a communication system adopted by the radio frequency part.

当一个无线通信系统自身资源不足,并且发现其他系统暂时未被利 When the lack of a wireless communication system of its own resources, and not found in other systems temporarily Lee

用的授权频i普的情况下,现有技术方案的解决办法可以分为两类。 With a case where authorization of the pilot P i, solutions prior art solutions can be divided into two categories. 一类是通过接纳控制的方法将新到达的用户业务分配到新的检测到的空闲频段内进行传输。 One is to reach a new assignment by the process of the user service into a new admission control detected idle frequency band for transmission. 另一类方法是通过异频切换的手段,将已经接纳到系统自身频段内的用户搬移到新的频段内进行数据传输。 Another method is by means of inter-frequency handover of the user has been received into the system in the band itself move to the new frequency bands for data transmission. 无论采用哪种方式,这两类方法都具有一个共性,就是对于一个特定用户的一个特定业务而言,它都是在唯一的一个独立频段上进行传输的。 Either way, these two methods have one thing in common, that is, for a particular user of a particular business, it is transmitted in only a single band. 用最简单的情况来说,当一个用户发起一个业务时,该业务要么在系统自身的频段内进行传输,要么在系统通过频语检测的手段发现的新的频段内进行传输。 In the simplest case, when a user initiates a business, which is transmitted either in-band system itself, either in the transmission system by means of frequency bands within the new language detection found.

由以上的论述可以知道,现有的技术方案存在以下问题: 一个通信系统占用其他通信系统的频段发射信号,当其他通信系统再次使用这段频傳时,该通信系统必须停止在该段频谱内发送用户数据。 Can be known from the above discussion, the following problems of the prior art solutions: transmitting a communication signal band occupied by the system to other communication systems, other communication systems when this frequent re-use, the communication system must be stopped within the segment spectrum send user data. 这时,工作于这段频镨的用户就面临通信中断的危险。 In this case, the user of this work to the frequency of praseodymium is in danger of interruption of communication. 当然,系统可以通过频语检测的手段再检测到新的频镨,将这些用户切换到其它新的频段内,但检测到新频谱的时间是不确定的,所以用户中断通信的时间也是不确定的。 Of course, the system can then be detected by means for detecting the frequency of the new language frequency praseodymium, these users will switch into the other new band, but the detection time of the new spectrum is uncertain, a communication interruption time the user is uncertain of. 若在较长的一段时间内都没有找到一段空闲的频语安排这些用户使用,则很有可能造成这些用户的掉话,即彻底的被迫中断了此次业务连接。 If no one has found an idle frequency language arrangements for these users over a long period of time, it is likely to cause these users dropped calls, that completely was interrupted the service connection.

具体实施方式 Detailed ways

下面参照附图对本发明进行更全面的描述,其中说明本发明的示例性实施例。 Wherein the description of the exemplary embodiments of the present invention DRAWINGS The invention is described more fully below with reference to.

本发明旨在通过将用户数据分层,利用多段不同频语来传输不同的数据层的方法来解决当一个频段内的原来系统到达,导致占用该频段发送数据的用户中断传输甚至掉话的问题。 The present invention is intended by the user hierarchical data, using different methods language different frequencies to transmit data segments to multiple layer system as a problem with the original reaches the band, the frequency band occupied by the user results in transmission data transmission interruption even dropped call problem . 本发明的核心思想是将一个业务流的基础层放到稳定的频段内进行传输,而将越靠上的增强层放到越不稳定的频段内传输的方法,来保证用户和网络的基本连接的可靠性。 The core idea of ​​the invention is a base layer of the traffic flow into the stable transmission band, and the reinforcing layer against the more unstable the process into the frequency band transmission, to ensure basic connectivity and network users reliability. 这样,当某个检测到的频段重新被它固有的系统所占用时,用户业务的服务不会出现中断,最多出现短时的业务质量下降的情况。 Thus, when a detected band re-occupied by its inherent system, the service user services without interruption, a momentary decline in the quality of service up to appear.

本发明主要方案包括: The main aspect of the invention comprises:

进行频镨监测,对每个频段的稳定性进行预测; Monitoring for frequency praseodymium, predict the stability of each frequency band;

用户业务数据流到达网络端后,获取对每个频段稳定性的预测结果,根据在业务传输质量中所起的作用大小分配到不同的频段,其中在业务传输质量中所起作用大的用户业务数据分配到稳定性较高的频段, 作用小的分配到稳定性较低的频段。 After reaching network user traffic data streams, for each frequency band predictor obtaining stability, in accordance with the size of the allocated transmission quality service in the role of the different frequency bands, wherein the transmission quality as a large business user service function data assigned to the higher frequency stability, the role of the small band allocated to the low stability.

其中,数据分层属于编码技术的范畴,目前在本领域已经有了相当成熟的研究。 Wherein the data belongs to the category hierarchical coding technique, the current research has been well established in the art. 以视频分层编码为例,现有的技术方案将一个视频流分为一个1^出层和多个增强层。 In layered coding the video as an example, the prior art scheme of a video stream is divided into a plurality of layers and the ^ 1 enhancement layers. 基础层包括多媒体片的基本表示,它维持了最低的通信质量。 The base layer comprises a sheet of substantially represent multimedia, it maintains the minimum communication quality. 增强层包括基础层之上的精细数据。 Enhancement layer comprises finely over the base layer data. 可以看出,增强 As can be seen, enhance

9层改善了多媒体片的质量。 9 improve the quality of the multimedia layer sheet. 该数据分层过程可以在用户终端执行,也能在网络端执行。 The data layering process may be performed in a user terminal, it can be performed on the network side. 如果用户业务数据流到达网络端时,未经过压缩编码技术进行分层,则网络端进一步对该用户业务数据流的数据根据在业务传输质量中所起的作用大小进行分层,将在业务传输质量中所起作用大的分配到基础层,将在业务传输质量中所起作用较小的分配到增强层。 If the user traffic data streams arrive at the network, not compressed hierarchical coding technique, then the hierarchical network further data of the user service data in the service stream according to the transmission quality in the role of the size of the transmitted traffic large mass of the role assigned to the base layer, the function assigned to the smaller enhancement layer quality of service transmission.

并且,可以在网络端创建频镨列表,将对每个频段的稳定性预测结果保存在频语列表中。 Also, you can create a list of praseodymium frequency on the network side, the stability of each forecast results will be stored in the frequency band of the language list. 所述频语列表中包含频段的范围、带宽、是否被授权使用、当前是否空闲以及该频段的稳定性预测值。 The frequency range of speech frequency band included in the list, bandwidth is authorized to use, and the stability is idle current prediction value of the band. 可以通过用户端和网络端联合监测每个频段的主用户系统在一个固定时间段内使用该段频镨(即该频段)的概率值来预测该频段的稳定性。 By the UE and the network for each band of the main joint monitoring system in a fixed time period a user to predict the stability of the band segment using the frequency Pr (i.e., the frequency) probability value.

所述用户业务数据在分配的频段内传输过程中,如果当前频段被占 The user service data in the transmission band allocation process, if the current band occupied

用,则可以再次查询频i普列表,对当前被占用分层中的数据流进行重新的频i脊分配。 With, you can search the list again frequency P i, for data stream currently occupied in the hierarchy i ridge frequency re-assignment.

并且,每隔固定周期对所述频镨列表进行更新。 And, at fixed frequency periodic updates the list of praseodymium. 如果所述用户业务数据在分配的频段内传输过程中,频镨列表发生更新,则再次查询频谱列表,判断当前所占用频段的稳定性信息是否有发生变化,若有变化, 则对该变化频段中传输的用于业务数据进行重新分配。 If the user traffic data in a frequency band during the allocated transmission frequency praseodymium list update occurs, the query again spectrum list, determines whether the current frequency band occupied by the stability of the information has changed, if changed, the change of the band transmission of traffic data for reallocation.

将该用户业务数据流中^出层数据分配到稳定频段进行传输,将该用户业务数据流中增强层数据分配到次稳定的频段进行传输。 The user service data stream ^ the layer data transmission bands assigned to stabilize, to enhance the user service data flow to the secondary distribution layer data transmission band of stability.

1、频段稳定性定义 1, frequency stability is defined

由于不同系统对于频段的使用在时间上具有非常大的差异性,比如广播电视系统、蜂窝通信系统、DVB系统、短距离通信系统等,都因为各自承载的业务各具特点,而在频段使用上的时间统计特性各不相 Because different systems using the band having a very large difference in time, such as a broadcast television system, a cellular communication system, DVB system, short-range communication systems, both because of their bearer services have different characteristics, and the use of the band in time statistical properties of the do not

同。 with. 在本发明中, 一个无线通信系统通过一定时间内,对于自身所处无线环境的监测,并能够抽象出不同频段的稳定性是本发明的前提条件。 In the present invention, a radio communication system by a certain time, for which the radio environment monitoring itself and can abstract different frequency stability is a prerequisite for the present invention. 这里所说的频段稳定性是用来表述一个特定频段是否能够出现长时间, 规律性空闲情况的量。 Stability band here is used to describe whether a specific frequency band, the amount of vacancy in regular time can occur. 当然,频段稳定性的具体定义方法有很多,在这里用主用户系统在一个固定时间段内使用该段频谱的概率值来表示。 Of course, there are many specific method of frequency stability is defined here in a fixed time period using the probability value of the segment with the spectrum represented by the primary user system. 其中,上面提到的主用户系统是指拥有该段频镨使用权的系统,也就是被频率管理机构授权使用特定频段的系统;与此相对的,后面将要提到的次级用户系统是指没有被授权使用某频段,而在检测到主用户系统不使用其固有频段后而擅自占用该频段工作的系统。 Wherein, the primary user of the system mentioned above means that the segment has a right to use the system frequency praseodymium, is authorized to use a particular frequency band of the system management mechanism; On the other hand, the user of the system to be later mentioned secondary means not authorized to use a band, and upon detecting a primary user does not use the system without its inherent band occupied by the system in this band. 也就是说,主用户系统和次级用户系统是对于一段特定频镨的相对概念,被授权使用该段频语的系统是主用户系统,未被授权使用该频段的系统是次级用户系 That is, the primary user and the secondary system is relatively user system concept for some specific frequency praseodymium, authorized to use the frequency segment is the primary language of the system user of the system, not authorized to use the band-based system is a secondary user

2、分层数据流的信道分配 2, the hierarchical data stream channel assignment

本发明的核心思想是将一个业务流的基础层放到稳定的频段内进行传输,而将越靠上的增强层放到越不稳定的频段内传输的方法,来保证用户和网络的基本连接的可靠性。 The core idea of ​​the invention is a base layer of the traffic flow into the stable transmission band, and the reinforcing layer against the more unstable the process into the frequency band transmission, to ensure basic connectivity and network users reliability. 数据在接收端再〗故合并。 Data receiving end so〗 combined. 需要强调的是,以下的行为都是由次级用户系统完成的。 It should be emphasized that the following actions are completed by a secondary user system.

业务的数据分层的一个例子,如图1所示,该例子中业务数据分为基础层l、增强层2、增强层3,……,增强层N。 An example of hierarchical data traffic, as shown in FIG. 1, the example service data L is divided into a base layer, the reinforcing layer 2, reinforcing layer 3, ......, enhancement layer N. 越靠下的数据层越是该业务连接的基础,保证了该业务最低的质量要求。 Data layer in closer and more the basis of the service connection, to ensure that the minimum service quality requirements. 越靠上的数据层传输的是越精细的数据。 On the upper layer data transmission is the data more finely. 例如:对于视频流来说,越靠上的数据层完成图#>的更细致,更清晰的功能;对于HTTP业务来说,可以将网页的文字数据定义为基础层,而将声音或链接的图片定义为增强层。 For example: For a video stream, the more reliable data on the completion of FIG layer #> a more detailed and clearer functions; for HTTP traffic, the character data of the page may be defined as the base layer, and the sound or linked picture defined as an enhancement layer. 也就是说, 对于不同的业务,具体的数据分层办法可以灵活掌握,但基本思想保持不变,就是越靠下层传输对于该业务来说越基本的数据。 That is, for different services, specific data tiered approach can be flexible, but the basic idea remains the same, that is more by the underlying transport the basic data for the business is.

当完成数据分层和频段稳定性计算后,将要进行本发明的核心部分:就是次级用户系统将不同的用户数据分层分配到具有不同稳定性的频段内进行传输。 After data is hierarchical and frequency stability calculations, it will be the core of the present invention: a secondary user system is different hierarchical data allocated to the user having a different stability band for transmission.

ii参见图2所示,将图1所示的数据分层分配到不同的频段中,基础层l分配到频段Bi (/^,;r),增强层2分配到频段B2 (/^,r)、增强层3 分配到频段B3 (/^j,r),……,增强层N分配到频段Bn (A„,r)。图2 右侧为频i普列表,需要说明的是,在图2中右侧的频i普列表应该是实时更新的。这个更新是由次级用户系统和工作在其系统内的用户联合检测实现的。优选7V;r排列顺序是从下向上依次变大。由于/Vr是对下一个T周期的预测,所以尸8,r应该在每经历一个T时段后进行更新。还有一点需要说明的是,出现在频谱列表中的频段都应当是在当前时刻主用户系统没有占用的频段。如果主用户系统突然出现占用了某个频段,应当在该表中将该频段删除;与此对应的,如果检测发现了新的没有被主用户系统占用的频段,应当在该表中进行添加,并依据其i^,;r的大小放置到相应的位置 ii Referring to FIG. 2, the data shown in FIG layered assigned to different frequency bands, the frequency bands allocated to the base layer l Bi (/ ^ ,; r), the reinforcing layer 2 to the band B2 (/ ^, r ), the reinforcing layer 3 to the frequency band B3 (/ ^ j, r), ......, N enhancement layer is assigned to the frequency band Bn (a ", r). FIG. 2 is a right side frequency list P i, to be noted that, in the right side in FIG. 2 i P pilot list should be updated in real time by the secondary user that the system is updated and work within their system user joint detection implemented preferably 7V;.. r is sequentially changed in the order from bottom to top a large Since / Vr is forecast for the next T cycle, so the corpse 8, r should be updated after each experiencing a period T. Another point to note is, appears in the list of spectrum bands should be at the current time the main user of the system not occupied by the primary user of the system band if suddenly occupied by a certain frequency band, the band should be deleted in the table; corresponding to this, if the detection is not found a new frequency band occupied by the main user of the system, It should be added to the table, and according to their size r i ^ ,; placed to the appropriate location ' '

需要说明的是,对于调制带宽不可变的系统,比如GSM的一个信道带宽为200kHz、 WCDMA的一个信道带宽为5MHz,只有当探测到的空闲频段的带宽大于一个信道带宽时才可以传输数据,当然,如果一段连续的空闲频段的带宽足以容纳好几个信道带宽的时候,也可以在该段频i普内部署多个分别位于不同频点的信道。 Incidentally, for the system of the modulation bandwidth is not changed, such as a channel bandwidth of GSM to 200kHz, a channel bandwidth of WCDMA is 5MHz, data can be transmitted only when the detected idle bandwidth frequency band is greater than a channel bandwidth, of course, , if the idle frequency band for a continuous bandwidth sufficient to accommodate several channel bandwidth when a plurality of channels may be deployed are located at different frequencies in the frequency segment i Pune. 如果一个通信系统的调制带宽是可变的,比如OFDM系统,那么它可以依据空闲频段的带宽采用灵活可变的带宽传输。 If a modulation bandwidth of the communication system is variable, such as OFDM systems, it may be employed in the flexible and variable according to the idle bandwidth of the transmission frequency bandwidth. 所以,考虑到以上两种情况,可以知道, 一个数据分层可以在一个或多个频段内传输; 一个频段可以容纳一个或多个数据层。 Therefore, considering the above two cases, it is known, a data slice can be transmitted within one or more frequency bands; a band can accommodate one or more data layers.

通常情况下,认为次级用户系统自身的频段稳定性是最高的,可以理解为是/Vr值为0的频段。 In general, the stability of the band that secondary users of the system itself is the highest, is understood to / Vr value of 0 bands. 因为自身频段的使用是由无线电管理机构授权的,是在任意时刻都可以任意使用的频段。 Because the band is using its own governing body authorized by the radio, the band is at any time can be arbitrarily used. 所以,在一般情况下, 一个数据流的基础层会放在次级用户系统自身的频段内传输。 Therefore, in general, a base layer data stream will be placed within the transmission band of the secondary user system itself.

下面描述本发明动态频镨分配的方法实施例的流程。 Following the method described process embodiment of the present invention, dynamic frequency allocation praseodymium embodiment. 在分配过程中会遇到两种情况: In the allocation process will encounter two situations:

第一种情况是在一个周期T内,次级用户系统使用的某个频段被主用户系统重新占用,这时候次级用户系统必须停止在该频段的信号发射,对数据流分层进行新的频段信道分配,具体步骤如图3中步骤306 -307所示。 The first case is in a period T, a sub-band used by the system user is occupied by a primary user system again, this time the secondary system user must stop the transmitted signal band, the data stream new stratified channel allocation band, the specific steps in the step 3 shown in FIG. 306-307. 需要说明的是,数据流分层信道重分配的原则不变,即将一个业务流的基础层放到稳定的频段内进行传输,而将越靠上的增强层放到越不稳定的频段内传输。 Incidentally, the data flow principle hierarchical channel reallocation constant, i.e. a base layer service stream into a stable transmission band, and the enhancement layer will depend on the band into more unstable transmission .

第二种情况是主用户系统没有重新占用频段,但由于频谱列表是实时更新的,在一个周期T结束后,次级用户系统会查询频谱列表,看每个频段的iVr值是否有变化,频段在列表中的位置是否有变化。 The second situation is the primary user of the system does not re-occupy the band, but the list is updated in real time spectrum, after the end of a period T, the secondary spectrum user system will check the list to see if the value of each iVr band change, band position in the list if there is a change. 如果有,则进行数据流分层信道重分配,如图3中步骤308 - 310所示。 If so, the data stream having a hierarchical channel reallocation, as shown in step 3 308--310 FIG.

需要说明的是,无论哪种情况,前期的流程都是相同的,即用户的业务到达,数据流分层,查询当前的频段列表,分层数据流信道分配, 传输分层数据流。 Note that, in either case, the pre-process is the same, i.e., the user reaches the service, the data stream having a hierarchical, query the list of frequency bands, the flow channel allocation hierarchy data, hierarchical data transport stream.

下面将列举一个实例,来说明将用户业务分配到不同频段的具体步骤及流程。 The following will list an example to illustrate the different frequency bands assigned to the user traffic of specific steps and processes.

步骤301,假设一个用户向网络端发起呼叫,请求接入网络并启动一个实时视频流的业务。 Step 301, assume a user initiates a call to the network, requesting access to the network and start a real-time video service stream.

步骤302,当网络端成功接纳该用户后,对用户的实时视频流进行分层。 Step 302, after receiving the success of the network user, the user's real-time video stream separated.

网络端可以设置一个频镨信息服务器,该频镨信息服务器能通过对自身所处无线环境的监测完成对频镨情况的分析,并保留分析的数据。 The network may be provided a frequency information server praseodymium, praseodymium the frequency monitoring information server via a wireless environment itself in which the frequency analysis of the complete situation praseodymium, and retain data analysis. 这里的数据应包括各段频语的带宽,哪些频段是官方规定为本系统所使用的频段(即本系统作为主用户系统所分配的频段),哪些频段是可认知的频段,本系统对这些频段的占用情况,以及这些频段的稳定性为何值进行分析。 The data presented here should include language segments frequency bandwidth, which is the official frequency band (i.e., as the primary user of the system assigned to the system band) used in the present system, which frequency bands are recognizable, the present system why these bands occupancy, and stability values ​​of these bands are analyzed. 由于频镨的情况是动态变化的,该频i普信息服务器还要对以上信息进行不断的更新。 Since the case of praseodymium is dynamic frequency, and the frequency information server P i but also on the above information is constantly updated. 其中,这里提到的频镨稳定性就是上面定义的i^,r参数。 Wherein the frequency stability of praseodymium mentioned here is defined above i ^, r parameter. 举例来讲,频谱信息服务器中可以以表格的形式组织信息,可称之为频镨列表。 For example in terms of spectral information server information may be organized in tabular form, the list may be referred to as frequency praseodymium. 频谱列表中应包含频段的范围、带宽、是否被授权使用、当前是否空闲以及频语稳定性预测值等信息。 The list should include the spectral range of the frequency band, the bandwidth, is authorized to use, the current language is idle, and frequency stability prediction value information and the like. 其中所述稳定性预测值可以直接由前文中所述主用户系统在一个固定时间段内使用该段频谱的概率值/Vr表示,概率值i^r越小,则该频段的稳定性越高。 Wherein the prediction value may be directly stability in a fixed time period using the probability value of the segment from the spectrum of the primary user hereinbefore system / Vr indicates, the smaller the probability value i ^ r, the higher the stability of the band . 在用户业务启动之前,网络端还需要由数据流分层模块对视频流进行分层,分为一个基础层和若干个增强层。 Before starting the user traffic, the network needs to layer a video stream from the data stream layering module is divided into a base layer and several enhancement layers. 将基础层解码后生成具有基础质量的视频信号,而增强层只能和基础层共同进行解码,解码后的信号质量较基础层有所改善。 The resulting decoded base layer having a base quality video signal, while the enhancement layer and the base layer can only be decoded together, the signal quality of the decoded base layer is improved more. 信源将每个层的比特流发往不同的频段,接收者除接收基础层之外,还可根据自己的接收能力选择接收其它的增强层。 The source of each bit stream layer is sent to different frequency bands, in addition to the recipient receiving the base layer, may also elect to receive additional enhancement layer according to its receiving capability. 并提供接收者在不同增强层之间切换的能力。 Recipient and provides the ability to switch between different reinforcing layers. 分层编码控制是现有技术目前为止解决异质性问题的最有效手段,每层流之间没有重复信息,但是以协议的复杂性作代价。 Hierarchical encoding control so far the most effective means to solve the prior art present problems of heterogeneity without duplication of information between each stream, but at the cost of complexity for the protocol.

步骤303,数据分层完毕后,系统查询频谱信息服务器,也就是图3中的频镨列表,获得相应的可用频段的信息,最重要的是获得每段频谱的稳定性信息。 Step 303, the hierarchical data is completed, the system queries the server spectral information, i.e. the frequency list praseodymium FIG. 3, the corresponding band information is available, the most important to obtain information about the stability of each segment of the spectrum. 具体的来讲,这个工作应由频谱分配服务器完成。 Specifically speaking, this should be done by the server to complete the spectrum allocation. 该频谱分配服务器的输入为频镨信息,数据流信息,以及一些其他系统必要信息。 The input frequency spectrum allocation server is praseodymium information, traffic information, and other necessary information systems. 数据流信息具体是指各个数据流的需求带宽等信息。 Specifically refers to the traffic information bandwidth requirement of each data flow and other information.

步骤304,频镨分配服务器的输出为将一个用户业务分层数据流映射到不同频段上的分配方式。 Step 304, the frequency output of praseodymium distribution server to a user service stream is mapped to the hierarchical data allocation on different frequency bands. 这在里,频镨分配的具体算法可以是多种多样的,但核心思想都是将越靠近基础层的数据流分配到越稳定的频段去。 This is where, praseodymium specific frequency allocation algorithm can be varied, but the core idea is the closer to the base layer data stream are assigned to the more stable the band to go. 举例来说,当次级用户系统检测到w段频i普稳定性各异的频段时, 可以将所有用户的基础层放在最稳定的频段内进行传输,如果该频段被占满,则可以将其他用户的^5出层放在次稳定的频段内进行传输。 For example, the system detects when the secondary user segment w i P frequency stability of different frequency bands, all the users may be on the most stable base layer is transmitted in the band, if the band is filled, may be the ^ 5 layers of other users in the band of stable transmission times. 然后在将所有用户的第一个增强层放在稳定性排在稍后的频段内进行传输, 以此类推。 And then transmitted to all users in the first reinforcement layer is placed in the later discharge stability band, and so on.

步骤305,分配完成后,就可以进行数据传输了。 Step 305, after the assignment is completed, the data can be transmitted.

步骤306,在传输过程中,可能出现某段认知频谱突然不可用的情况,比如该段频镨的主用户系统突然使用这段频i普,这时候,本系统立刻停止在该频段内发射信号,相应的,该段频i瞽的数据会出现暂时的终端或丟失。 Step 306, during transmission, the situation may occur suddenly unavailable certain cognitive spectrum, such as the segment praseodymium frequency main user using this system suddenly frequency P i, at this time, the system immediately stops transmitting in this band signal, corresponding to the i frequency blind segment data will be lost temporarily or terminal. 对于实时视频流来说,处于该频段传输的那部分分层数据流将会丟失,视频质量将会出现下降的情况。 For real-time video stream, the hierarchical data flow in that part of the band transmission will be lost, the situation drop video quality will emerge.

步骤307,这时,频语分配服务器需要再次查询频镨信息服务器中的频谱信息,并进入步骤311,对当前被占用分层中的数据流进行重新 In step 307, time, frequency allocation language server needs to query again frequency spectrum information praseodymium Information Server, and proceeds to step 311, the data stream that is currently being used in the re-stratified

14的频语分配,这样保证刚刚丟失的数据分层能够在其他的频段内继续传输。 14 frequency allocation language, thus ensuring just lost data transmission stratification can continue in other bands. 这时,频镨分配的原则仍旧不变。 In this case, the principle of praseodymium frequency allocation remains unchanged.

步骤308,另外,由于频i普信息服务器中的频谱信息是动态更新的,这里可以假设频镨信息的更新周期是T。 Step 308, Further, since the frequency spectrum information server information P i is updated dynamically, where it may be assumed update cycle of information is a frequency praseodymium T. 也就是说,原先稳定的频段可能在下个周期T内变为不稳定的频段。 In other words, the original stable band within a period T may become unstable in the next band.

这时,即使主用户系统没有到达,也可以根据频镨信息更新的情况,对分层数据流进行灵活的调整,重新将靠近基础层的数据流安排到较稳定的频段内进行传输。 In this case, even if the main user of the system does not reach, some cases may be praseodymium information update frequency, the data stream hierarchical flexible adaptation, re-close the base layer data flow to the more stable arrangement of the transmission frequency band. 具体参见步骤309-311。 DETAILED see step 309-311.

步骤309,频语分配服务器再次查询频镨信息服务器中的频语信 In step 309, the frequency distribution server again language query language letter frequency frequency praseodymium Information Server

each

步骤310,检查频镨信息服务器中的频谱列表各项参数,判断当前所占用频段的稳定性预测值等信息是否有发生变化,若没有,则返回步骤305,若有,则进入步骤311。 Step 310, the information server checks the frequency spectrum praseodymium list of the parameters, determines whether the currently occupied band prediction value stability information has changed, if not, returns to step 305, if so, the process proceeds to step 311.

步骤311,对分层数据流的信道进行重新分配。 In step 311, a hierarchy data stream channel reallocation.

步骤312,继续进行数据传输。 Step 312, continue data transmission.

综合以上分析的两种情况,可以知道,分层数据流信道重分配有两种触发方式。 Based on the above analysis of the two cases, it is known, the hierarchical data stream channel reallocations two trigger. 无论是主用户系统到达还是频谱信息的更新,都可能带来分层数据流对频镨的重分配。 Whether it is the primary user of the system to reach or update information spectrum, it is likely to bring traffic to the layered redistribution frequency praseodymium.

需要说明的是,上述流程中次级用户系统中的网络端和终端侧是需要互相配合完成这一过程的,由于网络端完成了频镨信息的收集和频段分配的决策工作。 Incidentally, the above process system of the secondary user terminal and the network side need to cooperate with each other to complete this process, since the network to complete the decision-making collection and praseodymium frequency band allocation information. 所以网络端需要告知终端数据传输的频率为多少,终端需务农据网络端的指示,将收发信机调整到适当的频率工作。 Therefore, the network terminal needs to inform the data transmission frequency is how much data the terminal needs to indicate the network's agriculture, the transceiver will be adjusted to an appropriate frequency. 本发明要求数据能够在多个频段进行同时传输,所以收发信机应该可以同时工作在多个频段,或者有多套收发信机各自工作在相应的频段。 The present invention requires a plurality of data can be transmitted simultaneously in frequency band, the transceiver may operate in a plurality of frequency bands should be, or how the respective sets of transceivers work simultaneously in the respective frequency band.
