Definitions
- the present invention relates to the field of communications technologies, and in particular, to a resource allocation method, apparatus, and system.
- BACKGROUND OF THE INVENTION With the rapid development of wireless communications, the demand for frequency bands continues to increase, and the demand for frequency bands by 2010 will be 200% to 300% in 2002. Since the existing band allocation strategy is fixed, the spectrum is not fully utilized. For example, according to the FCC (Federal Communications Commission) report, it can be seen from the two-dimensional statistics of time and space that the utilization rate of existing allocated spectrum is only between 15% and 85%.
- the wireless band is a scarce resource that is very expensive to manufacture. This also requires wireless communication technology to improve utilization.
- spectrum in mobile communications is mainly to allocate limited spectrum resources to different operators through the auction of spectrum resources or through government allocation. How to maximize the use of these spectrum resources by these operators and improve spectrum utilization, the industry has proposed some solutions.
- One of the more common methods of processing is to share spectrum resources between different systems through a spectrum server and a spectrum broker. For example, after the spectrum resource is allocated to the spectrum owner, the spectrum owner stores the spectrum resource in the spectrum server, and the spectrum server provides the spectrum resource to the spectrum purchaser who finally uses the spectrum resource.
- the spectrum purchaser is a system or an operator that actually provides a mobile communication service, and can initiate a spectrum resource request to the spectrum owner, specifically to the spectrum owner's spectrum server, in real time, and bid for the spectrum resource according to the auction principle;
- the spectrum server can allocate spectrum resources according to the results of bidding by multiple spectrum buyers, that is, spectrum resources are obtained by the spectrum buyers with high bids.
- spectrum purchasers can purchase and release as needed, realizing the sharing of spectrum resources among multiple systems or operators, improving spectrum utilization, and avoiding a lot of operators or systems.
- the use of spectrum resources is rarely used. However, this scheme will result in a large delay in the allocation of spectrum resources, because spectrum buyers are required to initiate spectrum bidding and spectrum requirements.
- the main technical problem to be solved by various embodiments of the present invention is to provide a resource allocation method for flexibly allocating various resources.
- a resource allocation method includes: accessing a network device to obtain pricing information for a resource usage object; and the access network device is the resource according to the pricing information of the resource usage object Use objects to allocate resources.

- the information obtaining module is configured to obtain pricing information of a resource usage object
- the resource allocation module is configured to allocate resources for the resource usage object according to the pricing information acquired by the information acquiring module.
- a wireless communication system is further provided, including: a centralized controller, and at least two network access devices, where different network access devices correspond to different networks or operators.
- the centralized controller is configured to obtain pricing information of a resource usage object in each network or each operator, and send the obtained pricing information to a network access device corresponding to each network or an operator; Determining, according to the pricing information of the resource usage object in each network or the operator, the total pricing information of the corresponding network access device, and allocating resources to each network access device according to the total pricing information of each network access device and sending the information to the network access device
- Each network access device is configured to: according to the pricing information of the resource use object in the network access device sent by the centralized controller, and the centralized controller is allocated to the network access Resource of the device, which is the resource in the network access device Use objects to allocate resources.
- Embodiments of the present invention allocates resources for resource use objects according to the pricing information, so that operators can flexibly price resource use objects according to needs, and the network side can flexibly allocate resources according to pricing. This enables the network side to allocate various resources more flexibly, and also improves resource utilization on the network side. And this way of allocating resources according to pricing, it is completely simple and easy to carry out resource allocation automatically.

- the access network device may be configured according to requirements, for example, may be based on related information of the resource use object, and may also be determined according to state information of the wireless resource used by the resource use object, and of course, may also consider this Two information can be changed in real time according to the above factors.
- the related information of the resource use object can be the importance of the resource use object, the revenue, the cost, the operator's operation strategy, and the resource use object in the carrier. The ratio of revenues in the market, etc. Status information of wireless resources, Then, the usage state of the wireless channel occupied by the resource usage object, whether the network is congested, the degree of congestion, the channel quality, the cell load status, the neighbor cell information, etc.
- the resource usage object may be a mobile terminal or a user, or It is a service.
- the processing method is the same for each specific object. Therefore, the following mainly describes the mobile terminal as an example.
- the information required for pricing may be measured by the network side when the mobile terminal accesses, for example, one or more of the usage status of the wireless channel occupied by the mobile terminal, congestion, congestion level, channel quality, and the like. Information. Thereafter, the pricing for the mobile terminal can be determined based on the information, and/or based on relevant information of the mobile terminal, such as the importance of the mobile terminal, business revenue, cost, and the like.
- Step 104 The access network device allocates resources for the resource usage object according to the received pricing information.
- the access network device can use the pricing information as a resource scheduling parameter to allocate resources to the resource usage object of the operator.
- the resource may include a spectrum resource, and may also include a transmit power of a signal, a device, and the like.
- the resource usage object may be allocated resources in descending order of the pricing information of the resource usage object.
- the resource usage object may be a mobile terminal, a user, or a service.
- C k (t) is the pricing information of the mobile terminal k.
- C k (t) is the pricing information of the mobile terminal k.
- determining the mobile terminal corresponding to the maximum value allocating resources for the determined mobile terminal k*, and then removing the mobile terminal k* from all mobile terminals, according to formula (0) Allocate resources to other mobile terminals. Subsequent processing is analogized until resources are allocated for all mobile terminals.
- the access state information, QoS (Quality of Service), and the like of the radio channel occupied by the resource use target may be further considered.
- the resource can be used for a resource with a high price and a good use state of the wireless channel, and the resource is preferentially allocated, or the resource is used with a high price and a high latency requirement of the QoS, and the resource is preferentially allocated.
- the access network device may also consider pricing information when establishing a radio bearer before performing resource allocation. For example, the priority of the radio bearer may be determined for each resource use object according to the level of the pricing information; the resource may be used for the resource with high pricing, and the resource of the resource using the low-priced resource may be preempted.
- access network devices can also consider pricing information when establishing connections or performing mobility management.
- the access network device can also consider pricing information when accessing the control. For example, a resource-used object with a high price can have a high access priority and can preempt resources of a resource-used object with a low price. In addition, the access network device may also determine whether the overall revenue of a certain cell is greater than its neighboring cell.
- the resource usage object of the cell edge may be switched to its neighboring cell, or the cell with a large overall benefit may be improved. Transmit power.
- the overall revenue may be determined according to the pricing of the resource usage object accessing the cell. The reason why the overall revenue of a certain cell is large is because the overall revenue of a cell is large, indicating that the resource usage rate of the cell is already relatively high. To fully utilize the resources of the system, some resources may be used. The use object switches to a neighboring cell with a small overall benefit, so that these resource use objects can use the resources of the neighbor cell.
- the access network device considers the pricing factor in the resource scheduling, so that the pricing information affects the scheduling of the shared resource, and the resource scheduling can be dynamically adjusted according to the adjustment of the pricing, so that the allocation of the shared resource is more flexible.
- the resource can be preferentially assigned to the operator with the highest price, thereby maximizing the resource value.
- the operator can perform dynamic pricing according to requirements, which makes the pricing more accurate, and avoids the problem that the pricing of the channel resources corresponding to the spectrum resources is inaccurate after the operators in the prior art price the spectrum resources.
- the use state information of the wireless channel used by the resource use object in the network can also be considered when allocating resources, it is also ensured that the channel can be allocated to the resource use object with good channel quality as much as possible, thereby improving system traffic.
- resource allocation may be re-allocated according to the updated channel usage status, thereby implementing dynamic adaptation to channel quality changes.
- LTE Long Term Evolution
- the spectrum resource allocation scheme of the present invention is implemented in an LTE system.
- LTE Long Term Evolution
- the mobile terminal is uniformly used here to represent an object that needs to allocate resources, but it is clear that the objects that need to allocate resources include mobile terminals, users, services, or other descriptions, which are implemented in the present invention.
- the pricing operation of step 101 above may be performed by the core network device of the LTE, and the resource allocation operation of the above step 104 is performed by the access network function entity of the LTE.
- channel resources are allocated based on a resource block (RB). It is assumed that there are N RBs and K mobile terminals in one cell of the system, and one mobile terminal can be allocated multiple RBs at one time, but one RB can only be allocated to one mobile terminal. Is the channel rate of mobile terminal k on RBn at time t. Assume that the operator's pricing for the mobile terminal k is G (0, which is called the pricing factor, then the resource allocation can be calculated according to the "(0 and C fc (t). See equation (1) for details.
- Kn can determine the RBs allocated to the mobile terminal k among the N RBs and K mobile terminals by using the formula. Specifically, the mobile terminal k can be calculated by the formula (1), and one or the maximum value is calculated. A plurality of RBs are allocated to the mobile terminal. At the same time, it is also necessary to satisfy the allocation condition that one RB can be allocated to one mobile terminal at a time, but one RB can only be assigned to one mobile terminal.
- the pricing factor is introduced into the resource allocation of the access network device, so that the mobile terminal or the service with high pricing obtains a greater opportunity for resource allocation, and if the pricing of the mobile terminal or service changes, or the operator If it is desired to change the pricing of the mobile terminal or service, the system can reallocate the resource in time according to the pricing, so that the resource can be allocated more flexibly; the allocation also considers the channel quality factor, that is, the above 3 ⁇ 4"W, so the system is When the resources are allocated, the channel state can be considered, so that the spectrum resources can be fully allocated. In addition, the fairness factor between different mobile terminals can also be considered, that is, the channel cannot be completely allocated to the mobile terminal with good channel quality, and the cell is avoided.
- the mobile terminal at the edge or the mobile terminal with poor channel quality can not get the transmission opportunity. It can be called proportional fairness. Still taking the LTE system as an example, the average rate that the mobile terminal has allocated can be used as the calculation factor, and the sum is t) the calculation of the resource allocation. The average rate is called a proportional fairness factor, denoted by T k (t), we can make use of the equation (2) for computing the resource allocation. R k n ⁇ t)C k jt)
- T k ⁇ t The RB is allocated to the mobile terminal k by the formula (2), which is similar to the foregoing formula (1), and details are not described herein again.
- T k (t) in the above formula (2) can be specifically calculated by the formula (3).
- the RB number assigned to the mobile terminal can be represented by ⁇ *.
- the formula (3) indicates that when an RB is allocated to the mobile terminal, the proportional fairness factor T k (t) represented by the mobile terminal is also updated, that is, a rate " « is added; when a mobile terminal is not allocated In the case of RB, it is necessary to reduce the proportional fairness factor.
- the proportional fairness factor T k (t) represented by the mobile terminal is also updated, that is, a rate " « is added; when a mobile terminal is not allocated In the case of RB, it is necessary to reduce the proportional fairness factor.
- the more RBs allocated by a mobile terminal the more the proportional fairness factor increases, and the less likely to be assigned to the RB next time, otherwise the next time it is allocated.

一种资源分配方法、 装置及*** 技术领域 本发明涉及通信技术领域, 具体涉及一种资源分配方法、 装置及***。 背景技术 随着无线通信的迅速发展, 对频带的需求不断提高, 到 2010年对频带的需求量将为 2002年的 200%~300%。 而由于现有的频带分配策略是固定的, 频谱并没有得到充分地利 用。 比如, 根据 FCC (Federal Communications Commission, 美国联邦通信委员会)报告 可以看出, 从时空二维统计, 现有已分配出去频谱的利用率只在 15%~85%之间。 而无线频段是造价非常昂贵的稀缺资源。 这也就更需要无线通信技术能够提高利用 率。 目前移动通信中的频谱使用,主要是通过频谱资源拍卖或通过政府分配的形式把有限 的频谱资源分配给不同的运营商。 如何使这些运营商的这些频谱资源得到最大化的使用, 提高频谱利用率, 目前业界已提出了一些解决方案。 较为常见的一种处理方式,是通过频谱服务器(spectrum server)和频谱代理(spectrum broker) 实现频谱资源在不同***之间的共享。 比如, 频谱资源分配给频谱所有者后, 频 谱所有者将频谱资源存放到频谱服务器中, 通过频谱服务器向最终使用频谱资源的频谱购 买者提供频谱资源。 该频谱购买者是实际提供移动通讯服务的***或运营商, 可以实时地 向频谱所有者, 具体地, 向频谱所有者的频谱服务器, 发起频谱资源请求, 并根据拍卖原 理进行频谱资源的竞价; 频谱服务器则可以根据多个频谱购买者竞价的结果进行频谱资源 的分配, 即由竞价高的频谱购买者获得频谱资源。 这种处理方式中, 频谱购买者可以根据需要进行购买及释放, 实现了频谱资源在多个 ***或运营商之间的共享, 提高了频谱的利用率, 避免了某个运营商或***拥有很多频谱 资源却很少使用的情况发生。 但该方案会导致频谱资源的分配时延很大, 因为需要频谱购 买者发起频谱竞价和频谱需求, 频谱服务器收到后, 要进行不同竞价的比较, 并且可能会 有多次的竞价, 最终确定后再把频谱资源信息通知频谱购买者, 由频谱购买者把频谱资源 分配给其***的接入设备。
这种竞价过程会很复杂, 需要多个频谱购买者进行多次的竞拍, 难以实现自动化, 并 且这种竞价方式很难灵活地分配资源, 导致资源利用率较低。 另一种常见的处理方式, 是在运营商间实现网络共享, 比如, 实现接入网共享或基于 漫游的共享。这两种共享方式通常是运营商之间签署一个共享协议,规定各种费用及分成。 也就是说, 在这两种共享方式中, 不同运营商业务的费用、 资源占据的比例等, 都是在协 议中规定好的。 由于是预先规定资源的比例, 这就很容易导致资源的利用率不高。 比如, 运营商 B当前业务较多, 虽然运营商 A当前业务较少, 该运营商 B也不能使用运营商 A 的资源。 如果需要改变资源分配, 则必须协商新的协议, 显然这会使得共享不够灵活。 综上所述, 目前的资源分配方法不够灵活, 资源利用率不高, 并且资源分配的自动化 程度较低。 发明内容 本发明各实施方式要解决的主要技术问题是提供一种资源分配方法,以灵活地分配各 种资源。
一方面, 提供了一种资源分配方法, 该方法包括: 接入网设备获取对资源使用对象 的定价信息; 所述接入网设备根据所述资源使用对象的所述定价信息, 为所述资源使用对 象分配资源。 另一方面, 还提供了一种接入网设备, 所述接入网设备包括: 信息获取模块和资源 分配模块。 其中: 所述信息获取模块, 用于获取资源使用对象的定价信息; 所述资源分配模块, 用于 根据所述信息获取模块所获取的定价信息, 为所述资源使用对象分配资源。 再一方面, 还提供了一种无线通信***, 包括: 集中控制器, 以及至少两个网络接 入设备, 不同网络接入设备对应不同的网络或运营商。 其中: 所述集中控制器, 用于获取各网络或各运营商中资源使用对象的定价信息, 将所获 取的所述定价信息分别发送给各网络或运营商对应的网络接入设备; 以及用于根据每个网 络或运营商中资源使用对象的定价信息确定对应的网络接入设备的总定价信息, 根据各网 络接入设备的总定价信息, 为各网络接入设备分配资源并发送给所述各网络接入设备; 各 网络接入设备, 用于根据所述集中控制器发送的、 本网络接入设备中的资源使用对象的定 价信息, 以及所述集中控制器分配给本网络接入设备的资源, 为本网络接入设备中的资源
使用对象分配资源。 本发明各实施方式通过为资源使用对象进行定价, 并根据该定价信息为资源使用对 象分配资源, 使得运营商可以根据需要对资源使用对象灵活定价, 并且网络侧可以根据定 价灵活地进行资源分配, 使得网络侧能够更加灵活地分配各种资源, 也提高了网络侧的资 源利用率。 并且这种根据定价进行资源分配的方式, 完全可以自动化地进行资源分配, 简 单、 易行。
图 1为本发明 个实施例的方法流程示意图; 图 2为本发明 个实施例中接入网设备的结构示意图;
图 3为本发明 个实施例中使用的 LTE***的结构示意图; 图 4为本发明 个实施例中一种无线通信***的结构示意图; 图 5为本发明一水实施例中另一种无线通信***的结构示意图( 具体实施方式 为使本发明的目的、 技术方案和优点更加清楚, 下面将结合附图对本发明作进一步 地详细描述。 步骤 101、 对资源使用对象进行定价, 把定价信息发给接入网设备。 其中, 该定价信息可以根据需要制定, 比如, 可以是基于资源使用对象的相关信息 制定, 还可以根据资源使用对象使用的无线资源的状态信息制定, 当然, 也可以同时考虑 这两个信息。 并且可以根据上述因素进行实时的改变。 该资源使用对象的相关信息, 可以是该资源使用对象的重要性、 收益、 成本、 运营 商的运营策略、 该资源使用对象在本运营商中所占的收益比率等。 无线资源的状态信息, 则可以是该资源使用对象占用的无线信道的使用状态、 网络是否拥塞、 拥塞程度、 信道质 量、 小区负荷状态、 邻小区信息等。 该资源使用对象可以是移动终端, 也可以是用户, 还可以是业务。 对于各种具体对 象而言, 其处理方法相同。 因此下面主要以移动终端为例进行说明。
在具体实现时, 可以是在移动终端接入时, 由网络侧测量定价所需的信息, 比如, 移动终端占用的无线信道的使用状态、 是否拥塞、 拥塞程度、 信道质量等中的一个或多个 信息。之后, 则可以根据这些信息, 和 /或根据该移动终端的相关信息, 比如移动终端的重 要性、 业务收益、 成本等, 决定给移动终端的定价。 另外, 在***运行的过程中, 网络侧还可以实时地上报信道质量的变化, ***则可 以根据该信息实时地调整定价。 步骤 104、 接入网设备根据收到的定价信息, 为该资源使用对象分配资源。 接入网设备则可以把定价信息作为一个资源调度的参数, 给运营商的资源使用对象 分配资源。 该资源可以包括频谱资源, 也可以包括信号的发射功率、 设备等。 具体来说, 可以是按照资源使用对象的定价信息从大到小的顺序, 为资源使用对象 分配资源。 如前所述, 该资源使用对象可以是移动终端, 也可以是用户, 还可以是业务。 对于 各种具体对象而言, 其处理方法相同, 因此, 下面主要以移动终端为例进行描述, 对于用 户以及业务的处理, 这里不再赘述。 在具体实现时, 可以是利用公式 (0)。 :* = max{Q( } 公式 (0 )
k 其中, Ck (t)是移动终端 k的定价信息。 使用该公式 (0), 具体就是确定出最大值所对应的移动终端, 为所确定的移动终端 k*分配资源, 之后, 从所有移动终端中去掉该移动终端 k*, 根据公式 (0) 再为其他移动 终端分配资源。 之后的处理依次类推, 直至为所有移动终端分配完资源。 另外, 上述步骤 104 中, 接入网设备在分配资源时, 还可以进一步考虑该资源使用 对象占用的无线信道的使用状态信息、 QoS ( Quality of Service, 服务质量))等。 比如, 可 以对定价高、 且无线信道使用状态好的资源使用对象, 优先分配资源, 或者, 对定价高, 且 QoS的时延特性要求高的资源使用对象, 优先分配资源。 接入网设备在进行资源分配之前, 还可以在建立无线承载时, 考虑定价信息。 比如, 可以根据定价信息的高低确定为各资源使用对象建立无线承载的优先级; 还可以为定价高 的资源使用对象, 抢占定价低的资源使用对象的资源。
类似地, 接入网设备还可以在建立连接或进行移动性管理时考虑定价信息。 比如, 可以对定价高的资源使用对象优先建立连接或实现切换; 还可以设置定价高的资源使用对 象可以抢占定价低的资源使用对象的资源。 当然, 如果是确定定价高的资源使用对象优先 切换, 则具体的切换操作应该是在上述步骤 104的资源分配之后执行。 接入网设备还可以在接入控制时考虑定价信息。 比如, 定价高的资源使用对象可以 具有高的接入优先级, 并且可以抢占定价低的资源使用对象的资源。 另外, 接入网设备还可以确定某个小区的整体收益是否大于其相邻小区, 如果大于, 则可以将该小区边缘的资源使用对象切换到其相邻小区, 或者提高该整体收益大的小区的 发射功率。 其中, 该整体收益可以根据接入该小区的资源使用对象的定价确定。 之所以在 某个小区的整体收益大时进行切换, 是因为, 如果一个小区的整体收益大, 则说明该小区 的资源使用率已经比较高了, 为充分利用***的资源, 则可以将一些资源使用对象切换到 整体收益小的相邻小区, 从而这些资源使用对象可以使用该相邻小区的资源。 另外, 还可 以通过切换, 在该收益小的相邻小区中为高级别的资源使用对象争取资源, 该高级别的资 源使用对象, 即为定价高的资源使用对象。 通过上述方式, 运营商只是根据资源使用对象进行定价, 而不对频谱资源或其他资 源进行定价, 这样可以避免对资源进行定价的方式带来的时延较大及效率降低的问题。 同 时, 接入网设备在资源调度中考虑了定价因素, 使得定价信息影响到共享资源的调度, 并 且可以根据定价的调整动态地调整资源调度, 使得共享资源的分配更为灵活。 对于多个请 求资源的运营商而言, 在资源分配中考虑定价因素, 还可以使得资源优先分配给出价最高 的运营商, 从而使得资源价值最大化。 并且, 运营商可以根据需要进行动态的定价, 使得定价更为准确, 避免了现有技术 中运营商对频谱资源进行定价后, 由于频谱资源对应的信道质量发生变化导致定价不准确 的问题。 另外, 由于在分配资源时还可以考虑网络中的资源使用对象所使用的无线信道的使 用状态信息, 因此还保证了信道能够尽量分配给信道质量好的资源使用对象, 提高了*** 流量。 并且, 如果信道使用状态有更新, 则还可以根据更新后的信道使用状态重新进行资 源分配, 从而实现了对信道质量变化的动态适配。 下面以 LTE (Long Term Evolution,长期演进)***为例, 以一个具体实施例来描述在
LTE***中实现本发明的频谱资源分配方案。 本领域普通技术人员可以理解, 其他通信系
统的实现与 LTE***类似, 因此不再一一详细描述。 另外, 如前所述, 为了简化描述, 这 里统一用移动终端来代表需要分配资源的对象, 但我们清楚, 需要分配资源的对象包括移 动终端、 用户、 业务或其他的描述, 它们在本发明实施例中没有本质的区别。 在 LTE***中, 可以由 LTE的核心网设备执行上述步骤 101的定价操作, 由 LTE的 接入网功能实体执行上述步骤 104的资源分配操作。 在 LTE***中, 信道资源是基于资源块 (RB, Resource Block) 为单位进行分配的。 假设***的一个小区中有 N个 RB, K个移动终端, 在一个时刻可以给一个移动终端分配 多个 RB, 但一个 RB只能分配给一个移动终端。 是移动终端 k在 RBn上、 在时刻 t 的信道速率。 假设运营商给移动终端 k的定价为 G (0, 将其称为定价因子, 则可以根据 该 "(0和 Cfc (t)进行资源分配的计算。 具体请见公式 (1 )。
^∑∑Rk n(t) k (0 公式 (1 )
k n 通过该公式可以确定 N个 RB和 K个移动终端中,为移动终端 k分配的 RB,具体来 说, 可以通过该公式(1 )对移动终端 k进行计算, 将计算出最大值的一个或多个 RB分配 给该移动终端。 同时还需要满足在一个时刻可以给一个移动终端分配多个 RB, 但一个 RB 只能分配给一个移动终端的分配条件。 本发明实施例通过将定价因子引入接入网设备的资源分配中, 使得定价高的移动终 端或业务, 获得资源分配的机会更大, 且如果移动终端或业务的定价更改, 或者说, 运营 商希望改变对移动终端或业务的定价, 则***可以根据该定价及时地对资源进行重新分 配, 从而能够更加灵活地分配资源; 该分配还考虑了信道质量因子, 即上述 ¾"W, 因此系 统在分配资源时可以考虑到信道状态的变化, 从而可以充分地分配频谱资源。 另外, 还可以考虑不同移动终端之间的公平因素, 即不能把信道完全分配给信道质 量好的移动终端, 避免在小区边缘的移动终端或信道质量差的移动终端得不到传输机会。 可以将其称为比例公平。仍以 LTE***为例, 具体可以把移动终端曾经分配到的平均速率 作为计算因子, 结合 和 (t)进行资源分配的计算。 将该曾经分配到的平均速率称为 比例公平因子, 用 Tk (t) 表示, 则可利用公式 (2)进行资源分配的计算。
Rk n{t)Ck jt)
公式 ( 2 )
Tk{t) 通过该公式(2)为移动终端 k分配 RB, 具体与前述公式(1 )类似, 在此不再赘述。 上述公式 (2) 中的 Tk (t) 具体可以由公式 (3 ) 算出。
(l --)Tk(t) + -R (t), k = k
+i) = 公式 ( 3 )
(l—)Tk (t), k ≠k 其中, k4表示选择出来的移动终端编号, ς是比例公平因子的窗口。分配给该移动终 端的 RB编号则可以用 η*表示。该公式(3 )表示当把一个 RB分配给移动终端 后, 该移 动终端所表示的比例公平因子 Tk (t) 也要更新一下, 即增加一个速率 "«; 当某个移动 终端没有被分配 RB时, 则需要减少其比例公平因子。 这样, 一个移动终端分配的 RB越 多, 其比例公平因子增加的也越多, 下次被分配到 RB的机会则越少, 反之则下次被分配 到 RB的机会就越多, 从而在很大程度上避免了资源分配不公平的情况出现。 对于无线通信***来说,通常都会同时存在多种网络,比如, GSM/ WCDMA/LTE等。 当然, 这些网络可以是由同一个运营商提供, 也可以由不同的运营商分别提供。 也可以只 存在一种网络, 但由不同的运营商分别提供, 为区别起见, 将不同运营商提供的网络看作 不同的网络。 对于上述几种情况, 在具体实现时, 均可以针对所有的网络或运营商设置一个接入 网设备。 其具体实现如前所述。 由于针对网络还是针对运营商, 其设置接入网设备的方法类似, 因此, 下面针对设 置多个接入网设备的描述中, 主要以针对网络进行接入网设备的设置为例进行说明。 可以针对不同的网络设置不同的接入网设备。比如,针对 GSM网络设置基站控制器, 针对 WCDMA网络设置 RNC, 针对 LTE网络设置 e B。 为区别起见, 将这些针对不同网 络的接入网设备称为网络接入设备。 还可以设置集中的控制设备, 称为集中控制器 ( C-Controller) , 通过该集中控制器根据不同网络的定价, 调整各网络的资源分配, 该 C-Controller也可以认为是一种接入网设备。 对于设置多个接入网设备的情况来说, 在上述步骤 101 中, 把定价信息发给接入网
设备, 具体可以是把各网络中移动终端的定价信息发给该 C-Controller, 该 C-Controller再 将各网络中移动终端的定价信息, 分别发给各网络的网络接入设备。 其中, 在步骤 101之后, 步骤 104之前, 还可以进一步包括, 由该 C-Controller根据 每个网络中移动终端的定价信息确定该网络的总定价信息, 比如, 对各网络的定价信息进 行加权累加, 将得到的加权值作为该网络的总定价信息, 并根据该总定价信息对各网络分 配***资源。 其具体分配方案与步骤 104类似。 对于步骤 104, 则各网络接入设备可以根据 C-Controller分配给本网络的资源, 对移 动终端进行资源分配。 当然, 定价信息如果需要根据无线资源的状态来确定, 则还可以由各网络或运营商 的网络接入设备上报本网络或本运营商的无线资源的状态信息给该 C-Controller。其中, 网 络接入设备上报本网络的无线资源的使用状态信息, 具体可以是根据本网络或本运营商中 各移动终端占用的无线资源的状态信息, 整合出本网络或本运营商的无线资源的状态信 息,并发送给 C-Controller;还可以是各网络接入设备直接上报各移动终端占用的无线资源 的状态信息, 由 C-Controller进行整合。 之后, 运营商则可以根据各网络的无线资源的状态确定各网络的整体定价标准, 比 如, 如果 GSM网络的信道状态较好, 则运营商可确定, 可以对该网络中的移动终端做较 高的定价, 反之则可以做较低的定价, 当然, 在对该 GSM网络中的各移动终端进行定价 时, 还可以根据各移动终端所占用的无线资源的状态信息分别进行定价。 如果需要采用其他信息进行定价, 则处理方案与根据无线资源的状态信息进行定价 类似。 总的原则是, 需要确定各网络的情况, 比如, 确定各网络中的无线资源的状态信息 和 /或各网络中的移动终端的相关信息, 根据该信息确定各网络间的整体定价标准; 再在各 个网络中, 根据各移动终端的情况, 比如, 根据本网络中移动终端占用的无线资源的状态 信息和 /或所述移动终端的相关信息, 当然, 还需要根据为各网络所确定的整体定价标准, 对各移动终端进行定价。 本发明实施例中, 实现上述步骤 101 的可以是运营商定价设备。 对于设置运营商定 价设备来说, 可以统一只设置一个; 还可以针对同一个运营商只设置一个; 也可以针对不 同的网络分别设置, 还可以针对不同的运营商分别设置。 各种设置方案, 都不会影响本发 明的实现。 该运营商定价设备还可以分别与核心网计费设备和接入网设备连接。
核心网计费设备向运营商定价设备发送定价参数, 该定价参数可以是移动终端在运 营商中所占的收益比率、 各运营商的收益信息等。 运营商定价设备则可以根据该定价参数对各运营商中的移动终端进行定价。 运营商 定价设备在定价后, 即可将定价信息发送给接入网设备。 另外, 运营商定价设备还可以接 收接入网设备发送来的信道状态信息, 并根据该信道状态信息以及该定价参数, 对各运营 商中的移动终端进行定价。 当然如果有多个运营商, 则该运营商定价设备还可以是多个, 不同的运营商定价设 备对应不同的运营商, 这种情况下, 核心网计费设备则可以将各运营商的定价参数分别发 给相应的运营商定价设备。 相应地, 接入网设备也需要将信道状态信息发给各运营商定价 设备。 下面再对本发明的装置和***实施例进行详细描述。 本发明实施例中, 接入网设备如图 2所示, 具体可以包括信息获取模块 201和资源 分配模块 204。 其中, 信息获取模块 201用于获取对资源使用对象的定价信息, 资源分配 模块 204则用于根据信息获取模块所获取的定价信息, 为该资源使用对象分配资源。 信息获取模块 201 所获取的定价信息, 具体可以是根据该资源使用对象占用的无线 资源的状态信息,和 /或所述资源使用对象的相关信息制定。无线资源的状态信息以及资源 使用对象的相关信息, 具体可以如前所述, 这里不再赘述。 对于 LTE***或类似***来说, 该资源分配模块根据定价信息进行资源分配, 具体 可以是按照定价信息的大小顺序, 为资源使用对象分配资源; 还可以是根据前述公式 (1 ) 或公式(2)计算出最大值, 将该最大值对应的 RB中, 满足在一个时刻能够给一个资源使 用对象分配多个 RB, 且一个 RB只能分配给一个资源使用对象这一条件的 RB, 分配给该 资源使用对象。 并且, 公式 (2) 中的 Tk (t)可以由上述公式 (3 )。 上述接入网设备还可以进一步包括多个网络实体, 这些网络实体在接入网设备的上 述资源分配模块进行资源分配之前,还可以设置该资源使用对象的接入和 /或切换等的处理 规则。 比如, 可以设置以下网络实体中的一个或多个。 设置第一网络实体。 该第一网络实体可以用于为定价高的资源使用对象, 优先建立 无线承载; 设置第二网络实体。 该第二网络实体可以用于设置定价高的资源使用对象能够抢占
定价低的资源使用对象的资源; 设置第三网络实体。 该第三网络实体可以用于对定价高的资源使用对象优先建立连 接; 设置第四网络实体。 该第四网络实体可以用于根据小区中资源使用对象的定价确定 小区的整体收益, 将整体收益大于相邻小区的小区中的资源使用对象切换到该相邻小区; 设置第五网络实体。 该第五网络实体可以用于根据小区中资源使用对象的定价确定 小区的整体收益, 提高整体收益大于相邻小区的小区的发射功率。 对于上述针对资源使用对象的网络实体来说, 在该网络实体执行对应的操作后, 会 发送相应的消息给资源分配模块, 比如, 第一网络实体可以发送无线承载建立完成消息; 第二网络实体可以发送资源能够抢占的通知消息; 第三网络实体可以发送连接建立完成消 息; 第四网络实体可以发送切换完成消息。 资源分配模块在收到这些消息后, 则可以执行 资源分配的处理。对于上述第五网络实体来说, 则可以不给资源分配模块发送消息, 当然, 也可以发送发射功率调整消息, 资源分配模块可以在根据该消息确定小区的发射功率提高 后, 再进行资源分配, 当然, 也可以不管该发射功率是否有调整, 直接为资源使用对象分 配资源。 还可以增加一个第六网络实体, 该网络实体可以用于对定价高的资源使用对象优先 进行切换; 相应地, 该切换具体应该在资源分配模块分配完资源后再执行。 对于 LTE***来说, 如图 3所示, 其中的核心网设备通常是移动管理实体 (MME, Mobility management entity) , 接入网功能实体可以包括 eNB, 该 eNB中又可以包括小区间 RRM ( Inter Cell RRM), 无线承载控制 (RB Control )、 连接移动控制 (CMC, Connection Mobility Control ) 无线接入控制 (RAC, Radio Admission control)、 动态资源分配和调度 (Dynamic Resource Allocation Schedule) 等。 因此, 对于 LTE***来说, 上述接入网设备具体可以是 eNB, 上述第一网络实体和 第二网络实体, 均可以是 RB control; 第二网络实体可以是 RAC; 第二、 第三和第六网络 实体, 均可以是 CMC; 第四网络实体和第五网络实体, 均可以是小区间 RRM。 比如, 以移动终端为例。对于 RB control来说, 可以在建立无线承载时, 将定价参数 考虑进来, 比如, 可以根据定价参数的高低调整无线承载的优先级, 以及设置定价高的移 动终端, 可以抢占定价低的移动终端的资源等。
对于 RAC来说, 在进行移动终端接入控制时, 可以把定价参数作为计算因子, 定价 高的移动终端具有高的优先级接入, 并可以抢占定价低的移动终端的连接。 对于 CMC来说, 在建立连接或进行移动性管理时考虑定价参数, 比如, 对定价高的 移动终端优先建立连接或实现切换, 以及定价高的移动终端, 可以抢占定价低的移动终端 的资源。 对于小区间 RRM来说, 如果一个小区的整体收益大于其相邻小区, 则可以将该小区 边界的移动终端切换到其相邻小区, 或者提高整体收益大的小区的发射功率。 从而可以通 过将一些移动终端切换到整体收益小的相邻小区来充分利用资源。另外,还可以通过切换, 在该收益小的相邻小区中为高级别的移动终端争取资源。 上述方案通过把定价信息引入各接入网设备的功能实体中, 使得运营商可以通过定 价来间接控制自己所占据的资源, 即如果运营商下的移动终端的定价高, 则本运营商可以 占据更多的资源。 同时还可以结合 QoS、 无线信道质量等接入网设备的功能实体通常会考虑的因素, 使得资源分配能够适应 QoS及无线信道质量的变化。 比如, 对于 QoS来说, 可以在资源 分配时, 根据 QoS中定义的时延特定, 在定价相同的前提下, 将时延要求高的数据的发送 优先级设定为高, 相应地, 该数据相关的移动终端的传输优先级也就为高了。 对于无线信 道质量来说, 则如前所述, 可以将无线信道质量好的移动终端的优先级设置为高。 该处理 具体可以由 LTE***中的小区间 RRM实现。 另夕卜,如前所述,***中通常都会同时存在多种网络, 比如, GSM/ WCDMA/LTE等, 还会存在多个运营商。可以针对不同的网络或不同的运营商设置不同的接入网设备。比如, 针对 GSM网络设置基站控制器, 针对 WCDMA网络设置 RNC, 针对 LTE网络设置 e B。 为区别起见, 将这些针对不同网络的接入网设备称为网络接入设备。 还可以设置 C-Controller, 通过该集中控制器根据不同网络的定价, 调整各网络的资源分配。 相应地, 本发明实施例的无线通信***具体可以包括至少两个网络接入设备 401, 以 及集中控制器 402, 如图 4所示。 资源使用对象具体仍然以移动终端为例。 其中, 该集中控制器 402可以用于获取各网络或各运营商中移动终端的定价信息; 并将所获取的各网络中移动终端的定价信息, 分别发送给各网络的网络接入设备 401。 该集中控制器 402还可以用于根据每个网络中移动终端的定价信息确定所述网络的
总定价信息; 根据各网络或运营商的总定价信息, 为各网络接入设备 401分配资源; 还用 于将分配的资源发送给各网络接入设备 401。 这里集中控制器 402为网络接入设备分配资 源, 实际上相当于是为该网络接入设备 401对应的网络或运营商分配资源。 各网络接入设备 401, 则可以用于根据集中控制器 402发来的移动终端的定价信息, 以及集中控制器 402为本网络接入设备 401分配的资源, 为该移动终端分配资源。 各网络接入设备具体可以包括图 2所示的信息获取模块和资源分配模块。 其中的信 息获取模块, 用于接收集中控制器发送的定价信息, 还用于接收集中控制器为本网络分配 的资源。 资源分配模块, 则根据集中控制器发送的定价信息, 以及集中控制器为本网络分 配的资源, 为相应的移动终端分配资源。 各网络接入设备显然也可以执行前述实施例中的各种具体实现。 当然, 各网络接入设备, 还可以进一步包括前述的第一至第五网络实体中的一个或 多个。 其具体实现与前述接入网设备的具体实现相同, 这里不再赘述。 对于上述集中控制器来说, 在为各网络接入设备分配资源时, 除了参考各网络的总 定价信息之外, 还可以参考该网络的无线信道状态、 QoS等信息。 各网络接入设备也是类 似。 以集中控制器来说, 可以接收各网络接入设备收集的各移动终端所占用的无线资源 的状态信息等, 根据该信息确定各网络的无线资源状态, 并根据该无线资源状态, 以及各 网络的总定价信息, 来确定为各网络分配的资源。 如前所述, 各网络的无线资源状态, 可 以由各网络接入设备根据其各移动终端所占用的无线资源的状态信息, 确定本网络接入设 备的无线资源的状态信息并上报给集中控制器; 也可以由网络接入设备直接上报各移动终 端所占用的无线资源的状态信息, 由集中控制器根据这些信息确定各网络接入设备的无线 资源的状态信息。 类似地, 网络接入设备则可以根据各移动终端所占用的无线资源的状态等信息, 该 移动终端的定价信息, 以及集中控制器为本网络分配的资源,为相应的移动终端分配资源。 对于本发明***来说, 如图 5所示, 还可以包括运营商定价设备 403, 由该运营商定 价设备为各移动终端进行定价。 具体可以是基于移动终端的相关信息制定, 还可以根据移 动终端使用的无线资源的状态信息制定, 当然, 也可以同时考虑这两个信息。 定价的具体 实现如前所述, 这里不再赘述。
对于以各种信息作为定价因素的情况来说, 该运营商定价设备首先需要获取这些信 息, 之后再进行定价。 如果只有一个接入网设备, 则运营商定价设备直接获取该接入网设 备上报的、无线资源的状态信息和 /或移动终端的相关信息, 并根据该信息对相应的移动终 端进行定价。 对于有多个接入网设备的情况, 即有多个网络接入设备, 且有集中控制器的情况, 可以由网络接入设备通过集中控制器将本网络的无线资源的状态信息和 /或移动终端的相 关信息发送给运营商定价设备, 该运营商定价设备则可以根据这些信息直接为移动终端进 行定价。 运营商定价设备还可以根据各网络中的网络接入设备确定并上报的、 本网络的无线 资源的状态信息和 /或移动终端的相关信息, 确定各网络间的整体定价标准; 运营商定价设 备再根据各网络间的整体定价标准,以及各网络的无线资源的状态信息和 /或移动终端的相 关信息, 对各移动终端进行定价。 运营商定价设备在进行定价时, 如果需要使用移动终端在运营商中所占的收益比率 等与计费相关的信息, 则运营商定价设备还可以与***的计费设备连接, 该计费设备将收 益等信息发送给运营商定价设备, 运营商定价设备还可以将定价信息发送给计费设备。 计 费设备则可以根据定价信息调整计费等。 另外, 对于上述运营商定价设备来说, 该运营商定价设备可以只有一个, 也可以针 对不同的网络分别设置, 或者针对不同的运营商分别设置。 各种设置方案均不影响本发明 的实现, 所不同的是, 如果有多个运营商定价设备, 则在信息交互时, 要将信息发送到对 应的运营商定价设备中。 综上, 对于本发明各实施例来说, 运营商只是根据移诸如移动终端、 业务、 用户之 类的资源使用对象进行定价, 而不对频谱资源或其他资源进行定价, 这样可以避免对资源 进行定价的方式带来的时延较大及效率降低的问题。 同时, 接入网设备在资源调度中考虑 了定价因素, 使得定价信息影响到共享资源的调度, 并且可以根据定价的调整动态地调整 资源调度, 使得共享资源的分配更为灵活。 对于多个请求资源的运营商而言, 在资源分配 中考虑定价因素, 还可以使得资源优先分配给出价最高的运营商, 从而使得资源价值最大 化。 并且, 运营商可以根据需要进行动态的定价, 使得定价更为准确, 避免了现有技术 中运营商对频谱资源进行定价后, 由于频谱资源对应的信道质量发生变化导致定价不准确
的问题。 另外, 由于在分配资源时还可以考虑网络中的资源使用对象所占用的无线资源的状 态信息等, 因此还保证了信道能够尽量分配给信道质量好的移动终端, 提高了***流量。 并且,如果信道使用状态有更新,则还可以根据更新后的信道使用状态重新进行资源分配, 从而实现了对信道质量变化的动态适配。 还可以考虑不同移动终端之间的公平因素, 即不能把信道完全分配给信道质量好的 移动终端, 避免在小区边缘的移动终端或信道质量差的移动终端得不到传输机会。 本领域普通技术人员可以理解, 实现上述方法实施方式中的全部或部分步骤是可以 通过程序来指令相关的硬件来完成, 所述的程序可以存储于计算机可读取存储介质中, 该 程序在执行时, 可以包括前述本发明各个实施方式的内容。 这里所称得的存储介质, 如: ROM/RAM、 磁碟、 光盘等。 虽然通过参照本发明的某些优选实施方式, 已经对本发明进行了图示和描述, 但本领 域的普通技术人员应该明白, 可以在形式上和细节上对其作各种改变, 而不偏离本发明的 精神和范围。
