Description

频谱资源配置方法及装置技术领域 Spectrum resource configuration method and device

本发明涉及小区频率配置技术，尤其涉及一种基于共享频率资源池进行频率资源配置的频谱资源配置方法及装置。背景技术 The present invention relates to a cell frequency configuration technology, and in particular, to a spectrum resource configuration method and apparatus for performing frequency resource configuration based on a shared frequency resource pool. Background technique

在无线网络环境中，由于用户规模化的移动，话务量会随着不同的时间段而出现从某区域迁徙到另一区域的现象，例如工作时间人们在中央商务区（CBD, Central Business District ) 商圈大量聚集，而下班后又向居民区大量迁徙，这就是所谓的 "潮汐话务" 现象。 "潮汐话务" 现象对建网初期的容量规划带来一定的困难，因为传统规划方式固定分配每个小区的载频和频点，如果按照平均话务组网，当话务量突然增加时，容易出现网络拥塞，无法接入的现象；如果按照最高话务量进行组网，虽然能保证通话质量，但是当话务量突然减少时又会使部分载频闲置，浪费网络资源。 In a wireless network environment, due to the large-scale movement of users, traffic volume may migrate from one area to another along different time periods, such as working hours in the Central Business District (CBD, Central Business District). The business district gathers a lot, and after work, it migrates to the residential area. This is the so-called "tidal traffic" phenomenon. The "tidal traffic" phenomenon brings certain difficulties to the capacity planning in the initial stage of network construction, because the traditional planning method fixedly allocates the carrier frequency and frequency point of each cell. If the traffic volume is suddenly increased according to the average traffic network. It is prone to network congestion and inaccessibility. If the network is deployed according to the highest traffic volume, although the call quality can be guaranteed, when the traffic suddenly decreases, some carrier frequencies will be idle and the network resources will be wasted.

在新一代通信设备中，基站收发信台采用射频拉远架构构建，其主要特点是基带资源和射频资源分离，形成两个独立的部分：基带单元（BBU, Base Band Unit )和射频远置单元（RRU, Remote Radio Unit )₀ BBU如同一个 "基带资源池"，集中管理所有的基带资源，以供多个 RRU共享； RRU 则负责对信号进行射频处理，覆盖不同区域的 RRU通过光纤连接到 BBU。目前业界出现了利用潮汐话务现象节省 BBU资源的配置的技术，即基带资源池方案。因为存在话务迁移现象的区域之间话务高峰存在一定的时间差，因此这些区域可以共享基带资源，由 BBU负责根据各个区域的话务量调度基带资源，另外在某些基带资源出现故障时， BBU还可以选取 "基带池" 中的其他资源进行替代，提高了***稳定性。在基带资源池方案中，各 RRU根据话务量的大小实时关闭或开启载频，并释放和申请关联的基带资源。但是各个载频使用的频率是按照一定的频率复用方式静态配置的，因此关闭载频分配的频点在其断电期间依然由其占用，从而造成频点资源的浪费，降低了***的频谱使用效率。发明内容 In the new generation of communication equipment, the base transceiver station is constructed by using the radio remote architecture. The main feature is that the baseband resources and the radio resources are separated to form two independent parts: a baseband unit (BBU) and a radio remote unit. (RRU, Remote Radio Unit) ₀ BBU acts as a "baseband resource pool", centrally manages all baseband resources for sharing by multiple RRUs; RRU is responsible for radio frequency processing of signals, and RRUs covering different areas are connected to BBUs through optical fibers. . At present, there is a technology in the industry that utilizes the tide traffic phenomenon to save the configuration of BBU resources, that is, the baseband resource pool solution. Because there is a certain time difference between traffic peaks in the area where traffic migration occurs, these areas can share baseband resources. The BBU is responsible for scheduling baseband resources according to the traffic volume of each area. In addition, when some baseband resources fail, The BBU can also replace other resources in the "baseband pool" to improve system stability. In the baseband resource pool solution, each RRU turns off or turns on the carrier frequency in real time according to the size of the traffic, and releases and associates the associated baseband resources. However, the frequency used by each carrier frequency is statically configured according to a certain frequency multiplexing manner. Therefore, the frequency of turning off the carrier frequency allocation is still occupied by the frequency band during the power-off period, thereby causing waste of frequency resources and reducing the spectrum of the system. Use efficiency. Summary of the invention

本发明的基本思想为：通过将多个小区设置为频率共享区，在该频率共享区中各小区共享动态频率资源池中的所有频率资源，各小区由于业务增加而需要加载载频时，从动态频率资源池中选取干扰最小的未分配频率或已分配给频率共享区中其他小区的频率并加载，当小区中业务减少需要关闭载频时，该关闭载频对应的频率未被其他小区使用时将被标识为未分配，以便供其他小区进行加载。 The basic idea of the present invention is: By setting a plurality of cells as frequency sharing zones, each cell in the frequency sharing zone shares all frequency resources in the dynamic frequency resource pool, and each cell needs to load a carrier frequency due to an increase in traffic, In the dynamic frequency resource pool, the undistributed frequency with the least interference or the frequency allocated to other cells in the frequency sharing area is selected and loaded. When the service in the cell needs to be turned off, the frequency corresponding to the closed carrier frequency is not used by other cells. The time will be identified as unallocated for loading by other cells.

为使本发明的目的，技术方案和优点更加清楚明白，以下举实施例并参照附图，对本发明进一步详细说明。以下说明仅仅是示例性的，而不是为了限制本发明的保护范围及其应用。本发明中，将若干小区配置为一个频率共享区。频率共享区为业务用户总量相对稳定、业务用户随时段在所述频率共享区迁移的小区区域，例如前述的潮汐话务相关小区。本发明中，一般是将具有潮汐话务的小区配置在同一个频率共享区内。另外，频率共享区为邻小区组成的区域，也可以为由互不为邻小区的小区组成的区域。本发明需要构造一个提供给频率共享区中各小区使用的动态频率资源池，小区周期性地对动态频率资源池中的频率进行干扰测量，由此得到各自的可用频率集，在需要加载新的频率时从可用频率集中挑选合适的频率使用，实现频率资源利用效率的最大化。本发明中，动态频率资源池可以以各小区为单位建立，即为频率共享区中各小区分别建立动态频率资源池，也可以以多个小区构成的频率共享区组为单位建立动态频率资源池。 The present invention will be further described in detail below with reference to the accompanying drawings. The following description is merely exemplary and is not intended to limit the scope of the invention and its application. In the present invention, several cells are configured as one frequency shared area. The frequency sharing area is a cell area where the total number of service users is relatively stable, and the service user migrates in the frequency sharing area at any time, for example, the aforementioned tidal traffic related cell. In the present invention, cells with tidal traffic are generally arranged in the same frequency sharing area. In addition, the frequency sharing area is an area composed of neighboring cells, and may also be an area composed of cells that are not neighboring cells. The present invention needs to construct a dynamic frequency resource pool for use by each cell in the frequency sharing area, and the cell periodically performs interference measurement on the frequency in the dynamic frequency resource pool, thereby obtaining respective available frequency sets, and need to load new ones. At the frequency, the appropriate frequency is selected from the available frequency sets to maximize the utilization efficiency of the frequency resources. In the present invention, the dynamic frequency resource pool may be established in units of cells, that is, a dynamic frequency resource pool is established for each cell in the frequency sharing area, and a dynamic frequency resource pool may be established by using a frequency sharing block group composed of multiple cells. .

图 1为动态频率资源池示意图，如图 1所示，本发明中的动态频率资源池中的频率可分为四种不同的状态，分别是：未分配不可用状态、未分配可用状态、已分配不可用状态和已分配可用状态，其中，未分配不可用状态为，频率未被分配且干扰不满足门限要求，此状态的频率不能被分配。未分配可用状态为，频率未被分配且干扰满足门限要求，此状态的频率可以被分配。已分配不可用状态为，频率已被分配且干扰不满足门限要求，此状态的频率不能被分配。已分配可用状态为，频率已被分配且干扰满足门限要求，当所有可用频率均被分配时，此状态的频率才能被分配。 FIG. 1 is a schematic diagram of a dynamic frequency resource pool. As shown in FIG. 1 , the frequency in the dynamic frequency resource pool in the present invention can be divided into four different states, namely: an unallocated unavailable state, an unallocated available state, and a The allocation unavailable state and the allocated available state, wherein the unallocated unavailable state is, the frequency is not allocated, and the interference does not satisfy the threshold requirement, and the frequency of the state cannot be allocated. The unassigned available state is that the frequency is not assigned and the interference meets the threshold requirement, and the frequency of this state can be assigned. The assigned unavailable state is that the frequency has been assigned and the interference does not meet the threshold requirement, and the frequency of this state cannot be assigned. The available states are assigned, the frequency has been assigned and the interference meets the threshold requirement, and the frequency of this state can be assigned when all available frequencies are assigned.

频率的状态需周期性地确定。当基站 BTS处于初始状态时，首先对高优先级 TCH频率的频点进行预分配，并将这些频率状态从未分配状态调整为已分配状态。接着小区开始对动态频率资源池中所有频率进行干扰测量，当频率干扰满足门限要求时，则放入本小区的可用频率集中。 The state of the frequency needs to be determined periodically. When the base station BTS is in the initial state, the frequency points of the high priority TCH frequency are first pre-allocated, and the frequency states are adjusted from the unassigned state to the allocated state. Then, the cell starts to perform interference measurement on all frequencies in the dynamic frequency resource pool. When the frequency interference meets the threshold requirement, it is placed in the available frequency set of the current cell.

当小区由于业务增加需要加载载频时，从可用频率集中挑选干扰最小的处于未分配状态的频率进行加载，并将频率的状态从未分配状态调整为已分配状态，如果可用频率集中所有频率都已被使用，则挑选干扰最小的已分配给其他小区的频率进行加载。 When the cell needs to load the carrier frequency due to the increase of the service, the frequency with the smallest interference in the unallocated state is selected from the available frequency set to be loaded, and the state of the frequency is unallocated from the unallocated state to The assigned state, if all frequencies in the available frequency set have been used, pick the frequency that has been allocated to other cells with the least interference for loading.

当小区由于业务减少需要关闭相应载频时，如果该关闭载频对应的频率没有被其他小区使用，则将该关闭频率的状态则从已分配状态调整为未分配状态。 When the cell needs to turn off the corresponding carrier frequency due to the decrease of the traffic, if the frequency corresponding to the off carrier frequency is not used by other cells, the state of the closed frequency is adjusted from the allocated state to the unassigned state.

图 2为潮汐话务的六小区拓朴结构示意图，如图 2所示，示出了 6个小区（小区 1至小区 6 )为一个频率共享区的示例，假设对各小区进行频率静态配置时，每个小区需配置 5个 TCH载频。这样， 6个小区的 TCH载频总共需要使用 30个频点。而实际应用时，由于潮汐话务现象，平均每小区只需开启 4个 TCH载频，使用 24个频点即可满足需求。以下结合图 2所示的小区的频率配置情况，进一步阐明本发明技术方案的本质。 2 is a schematic diagram of a six-cell topology structure of a tidal traffic. As shown in FIG. 2, an example in which six cells (cell 1 to cell 6) are one frequency sharing zone is shown, and it is assumed that frequency static configuration is performed for each cell. Each cell needs to be configured with 5 TCH carrier frequencies. Thus, the TCH carrier frequency of the six cells requires a total of 30 frequency points. In actual application, due to the tidal traffic phenomenon, it is only necessary to turn on 4 TCH carrier frequencies per cell, and 24 frequency points can be used to meet the demand. The essence of the technical solution of the present invention is further clarified below with reference to the frequency configuration of the cell shown in FIG.

图 3为本发明实施例的频谱资源配置方法的流程图，如图 3所示，本发明频谱资源配置方法包括以下步驟： FIG. 3 is a flowchart of a method for configuring a spectrum resource according to an embodiment of the present invention. As shown in FIG. 3, the method for configuring a spectrum resource according to the present invention includes the following steps:

初始化静态配置网络广播控制信道（ BCCH, Broadcast Control Channel ) 和高优先级业务信道（TCH, Traffic Channel )载频频点；假设每个小区有 1个 BCCH载频和 2个 TCH载频进行了静态频点配置。并且***共使用了 24个 TCH频点，小区 1可静态配置频点为 { 1 , 7} , 小区 2为 {3, 9} , 小区 3为 {6, 12} , 小区 4为 {5, 11 } , 小区 5为 {2, 8} , 小区 6为 {4, 10}。 Initialize statically configured network broadcast control channel (BCCH, Broadcast Control Channel) and high priority traffic channel (TCH, Traffic Channel) carrier frequency points; assume that each cell has 1 BCCH carrier frequency and 2 TCH carrier frequencies for static frequency Point configuration. And the system uses a total of 24 TCH frequency points, cell 1 can statically configure the frequency point as { 1 , 7} , cell 2 is {3, 9} , cell 3 is {6, 12} , cell 4 is {5, 11 }, cell 5 is {2, 8}, and cell 6 is {4, 10}.

步驟 301 : 为每个小区构建频率资源池，下面以图 2所示拓朴结构的六小区为例说明本发明的动态频率资源池的构造过程，首先根据小区的地理位置，以及潮汐话务特征，将图 2所示的小区分为三个频率共享区组，分别为：（1 , 5 )、 ( 2, 6 )、 ( 3 , 4 ), 其中，频率共享区组中的每一对小区位置不相邻。确定共享频率小区组后，就可以按照如下步驟为每个共享频率组构造频率资源池： Step 301: Build a frequency resource pool for each cell. The following describes the construction process of the dynamic frequency resource pool of the present invention by taking the six cells of the topology shown in FIG. 2 as an example. First, according to the geographic location of the cell, and the tidal traffic characteristics. The cell shown in FIG. 2 is divided into three frequency sharing block groups, which are: (1, 5), (2, 6), (3, 4), wherein each pair of cells in the frequency sharing block group The location is not adjacent. After determining the shared frequency cell group, you can construct a frequency resource pool for each shared frequency group as follows:

a )初始化参数 i=0, j=0, p=0, n=共享频率组数， m=共享频率小区总数， C_k=共享频率组 k中的小区数； a) Initialization parameters i=0, j=0, p=0, n=number of shared frequency groups, m=shared frequency cell total Number, C _k = number of cells in the shared frequency group k;

b)令 j=l, i=l, p=l, 将第 i个频率分配到共享频率组 j; b) let j = l, i = l, p = l, the ith frequency is assigned to the shared frequency group j;

C) i=i+l, 若 1〉***总频率数，则当前流程结束； C) i=i+l, if 1> total system frequency, the current process ends;

d)判断如下条件：若 i- (p-1) xm小于或等于 ¾₌₁ , 将第 i个频率分配到共享频率组 j, 执行步驟 c; 若 i- (P-1) xm大于 ¾_=:1 , 则执行步驟 e; e) j=j+l, 判断如下条件： d) Determine the following conditions: If i-(p-1) xm is less than or equal to 3⁄4 ₌₁ , assign the ith frequency to the shared frequency group j, and perform step c; if i- (P-1) xm is greater than 3⁄4 _{= :1} , then execute step e; e) j=j+l, judge the following conditions:

若 j小于或等于 n, 将第 i个频率分配到共享频率组 j, 执行步驟 c; If j is less than or equal to n, assign the ith frequency to the shared frequency group j, and perform step c;

若 j大于 n, 执行步驟 f; If j is greater than n, perform step f;

f) p=p+l, j=l, 将第 i个频率分配到共享频率组 j, 执行步驟(。 f) p=p+l, j=l, assign the ith frequency to the shared frequency group j, and perform the step (.

或者，也可以按下述方式分配频点： Alternatively, you can assign frequency points as follows:

第一轮频点分配过程：频点 1、 2分配给共享频率区组 1, 频点 3、 4分配给共享频率区组 2, 频点 5、 6分配给共享频率区组 3; The first round frequency allocation process: frequency points 1, 2 are assigned to the shared frequency zone group 1, frequency points 3, 4 are assigned to the shared frequency zone group 2, and frequency points 5, 6 are assigned to the shared frequency zone group 3;

第二轮频点分配过程：频点 7、 8分配给共享频率区组 1, 频点 9、 10 分配给共享频率区组 2, 频点 11、 12分配给共享频率区组 3; 第四轮频点分配过程：频点 19、 20分配给共享频率区组 1, 频点 21、 22分配给共享频率区组 2, 频点 23、 24分配给共享频率区组 3。 The second round of frequency allocation process: frequency points 7, 8 are assigned to shared frequency block group 1, frequency points 9, 10 are assigned to shared frequency block group 2, frequency points 11, 12 are assigned to shared frequency block group 3; fourth round Frequency point allocation process: Frequency points 19, 20 are assigned to shared frequency block group 1, frequency points 21, 22 are assigned to shared frequency block group 2, and frequency points 23, 24 are assigned to shared frequency block group 3.

最终得到共享频率区组 1的动态频率资源池为 {1, 2, 7, 8, 13, 14, The dynamic frequency resource pool of the shared frequency block 1 is finally obtained as {1, 2, 7, 8, 13, 14,

19, 20}, 共享频率区组 2的频率资源池为 {3, 4, 9, 10, 15, 16, 21, 22}, 共享频率区组 3 的频率资源池为 {5, 6, 11, 12, 17, 18, 23, 24}。其中频点 1~12在步驟 1中已分配。 19, 20}, the frequency resource pool of the shared frequency block 2 is {3, 4, 9, 10, 15, 16, 21, 22}, and the frequency resource pool of the shared frequency block 3 is {5, 6, 11, 12, 17, 18, 23, 24}. The frequency points 1~12 are assigned in step 1.

步驟 302, 判断可用频率集的计算周期是否已到来。 Step 302: Determine whether a calculation period of the available frequency set has arrived.

可用频率集的计算周期到来时，对动态频率资源池中各频率进行干扰确定，确定当前可用频率集，以更新本小区的当前可用频率集。步驟 303 , 根据干扰计算算法更新各频率的干扰情况。 Interfering with each frequency in the dynamic frequency resource pool when the calculation period of the available frequency set arrives Determine, determine the current set of available frequencies to update the current set of available frequencies for the cell. Step 303: Update the interference condition of each frequency according to the interference calculation algorithm.

各小区实时测量动态频率资源池中各频率的干扰情况，并周期性地计算其可用频率集。当一个可用频率集计算周期到达时，小区首先根据测量的结果计算各频率的干扰情况。 Each cell measures the interference of each frequency in the dynamic frequency resource pool in real time, and periodically calculates its available frequency set. When an available frequency set calculation period arrives, the cell first calculates the interference of each frequency based on the measured result.

计算各个频率干扰情况的一个方法是根据上行干扰带来计算。因为基站会周期性地对空闲信道的上行干扰带进行测量，因此可以在测量空闲信道干扰带时对动态频率资源池中频率进行扫描获取它们的干扰情况，各频率干扰情况采用 8个信道干扰带等级的平均值表征，当频率的干扰带级别超过特定门限时就认为此频率不可用，而不放入小区可用频率集，可用频率按干扰带等级从 d、到大的顺序依次放入可用频率集。 One way to calculate the interference of each frequency is to calculate it based on the uplink interference. Because the base station periodically measures the uplink interference band of the idle channel, the frequency in the dynamic frequency resource pool can be scanned to obtain their interference condition when measuring the idle channel interference band, and the eight channel interference bands are used for each frequency interference situation. The average value of the level is characterized. When the interference level of the frequency exceeds a certain threshold, the frequency is considered to be unavailable, and the available frequency set of the cell is not put, and the available frequency is sequentially put into the available frequency according to the interference band level from d to large. set.

也可以由手机测量上报的本小区和邻接小区的 BCCH电平估算各频率的上下行干扰情况。 The uplink and downlink interference of each frequency may also be estimated by the mobile phone measuring the BCCH level of the reported neighboring cell and the neighboring cell.

本发明中，干扰情况的确定如下表 1所示。 In the present invention, the determination of the interference situation is as shown in Table 1 below.

步驟 304, 更新小区可用频率集。 Step 304: Update a set of available frequencies of the cell.

将干扰计算结果与表 1 所示的门限要求进行比较，当频率干扰满足要求时，则放入可用频率集。通过周期地计算动态频率资源池中各频率的干扰情况，能及时确定出态频率资源池中哪些频率是属于本小区可用的频率。 The interference calculation results are compared with the threshold requirements shown in Table 1. When the frequency interference meets the requirements, the available frequency set is placed. By periodically calculating the interference of each frequency in the dynamic frequency resource pool, it is possible to determine in time which frequencies in the outbound frequency resource pool belong to the frequencies available to the local cell.

表 1 步驟 305 , 判断是否有小区需要关闭载频。 Table 1 Step 305: Determine whether a cell needs to turn off the carrier frequency.

当小区因为话务量的变化如当前业务减少而需要关闭载频时，则需要对该关闭载频对应频率的状态进行更新。 When the cell needs to turn off the carrier frequency because the traffic volume changes, such as the current service is reduced, the state of the frequency corresponding to the off carrier frequency needs to be updated.

步驟 306 , 确定是否有其他小区使用该关闭的频率。 Step 306: Determine whether there are other cells using the closed frequency.

步驟 307 , 将该关闭频率的状态标记为 "未分配"。 Step 307, marking the status of the shutdown frequency as "unallocated".

如果确定频率共享区内没有其他频率使用该关闭频率，则将该关闭频率的状态标记为 "未分配" If it is determined that there is no other frequency in the frequency sharing area to use the shutdown frequency, the status of the shutdown frequency is marked as "unallocated"

步驟 308 , 确定是否有小区加载新载频。 Step 308: Determine whether a cell loads a new carrier frequency.

当小区因为业务需求如业务增加而需要加载载频时，从可用频率集中查找干扰最小的"未分配 "的频率进行加载，并更改该加载的新频率状态为 "已分配"，如果可用频率集中所有频率都为"已分配"状态，则挑选干扰最小的当前分配给其他小区的频率进行加载。也即，频率共享区中各小区可以互相使用其他小区已加载的频率，这是由于频率共享区中各小区互不为邻小区，使用相同的频率所带来的干扰相对较小。 When the cell needs to load the carrier frequency because of the business demand, such as the increase of the service, the frequency of the "unallocated" with the least interference is searched from the available frequency set, and the new frequency state of the load is changed to "allocated" if the available frequency is concentrated. All frequencies are in the "assigned" state, and the frequency currently assigned to the other cells with the least interference is selected for loading. That is, each cell in the frequency sharing area can mutually use the frequency that other cells have loaded. This is because each cell in the frequency sharing zone is not a neighboring cell, and the interference caused by using the same frequency is relatively small.

综上所述本发明所述的方法构造一个动态频率资源池， ***中的频率动态地从该动态频率资源池中挑选合适的频率进行使用。使用本发明的技术方案后，频率共享区各 TCH频率占用的频率数为 24个，远少于不使用本发明技术方案时的占用频率数 30个，从而实现了频率节约。 In summary, the method of the present invention constructs a dynamic frequency resource pool, and the frequency in the system dynamically selects a suitable frequency from the dynamic frequency resource pool for use. After the technical solution of the present invention is used, the number of frequencies occupied by each TCH frequency in the frequency sharing area is 24, which is far less than 30 occupied frequencies when the technical solution of the present invention is not used, thereby achieving frequency saving.

工业实用性 Industrial applicability

本发明通过将多个小区设置为频率共享区，在该频率共享区中各小区共享动态频率资源池中的所有频率资源，各小区由于业务增加而需要加载载频时，从动态频率资源池中选取干 4尤最小的未分配频率或已分配给频率共享区中其他小区的频率并加载，当小区中业务减少需要关闭载频时，该关闭的载频对应的频率未被其他小区使用时将被标识为未分配，以便供其他小区进行加载。从而保证了频率共享区中各小区之间的频率资源共享，不必为每个小区静态配置最大业务承载频率，在保证小区业务承载的基础上，节省了***的频率资源。 The present invention sets a plurality of cells as frequency sharing zones, and each cell in the frequency sharing zone shares all frequency resources in the dynamic frequency resource pool. When each cell needs to load a carrier frequency due to an increase in traffic, the dynamic frequency resource pool is selected from the dynamic frequency resource pool. Selecting the undistributed frequency of the trunk 4 or the frequency allocated to other cells in the frequency sharing area and loading, when the traffic in the cell needs to be turned off, the frequency corresponding to the closed carrier frequency is not used by other cells. It is identified as unallocated for loading by other cells. Therefore, the frequency resource sharing between the cells in the frequency sharing area is ensured, and the maximum service bearer frequency is not required to be statically configured for each cell. In the above, the system's frequency resources are saved.
