- the inventors have found that the above prior art has at least the following problems: Whether it is a WCDMA system or E-HSPA that introduces HSUPA, for a non-serving cell base station, in the process of MDC, it is necessary to All service data is allocated demodulation resources. In actual application scenarios, for services with certain service characteristics (such as high-speed non-real-time services), the gain of the MDC is not obvious. In this way, it is equivalent to the cost of using a relatively large demodulation resource, and a relatively small gain is obtained, which is somewhat worthwhile for the system as a whole.
- the CE static allocation method makes the utilization of CE resources inefficient, which makes the system's throughput rate low.

- FIG. 2 is a schematic diagram of a demodulation resource allocation method according to a second embodiment of the present invention.
- FIG. 3 is a schematic structural diagram of a base station according to a third embodiment of the present invention. detailed description
- the embodiments of the present invention are mainly described by using a WCDMA and an E-HSPA system as an example. However, it is to be understood that the technical solutions provided by the embodiments of the present invention are equally applicable to systems such as LTE/SAE.
- the names of the network elements in different systems are different.
- the radio network controller is the RNC
- the base station is the NodeB
- the E-HSPA is the enhanced base station NodeB+
- the LTE system is the evolved base station E-NodeB.
- the network nodes performing MDC are different network elements in different systems, such as RNC in the WCDMA system and the serving cell base station in the E-HSPA system (enhanced base station NodeB+, Serving network controller (SRNC function), in the LTE system, is a serving cell base station (evolved base station E-NodeB).
- RNC Radio Network Controller
- E-HSPA enhanced base station NodeB+, Serving network controller
- SRNC function Serving network controller
- the HSUPA uses the HARQ (Hybrid Automatic Retransmission Request) retransmission, and the HARQ retransmission results in the same MAC (Medium Access Control) layer rate.
- MAC Medium Access Control
- the soft handover technology is also applied in the HSUPA.
- the UE establishes a wireless link with multiple cells, and consumes more CE resources.
- the uplink CE resources of the base station may become a bottleneck affecting the number of users and the throughput rate.
- RL radio link
- the CE required for the average rate or the instantaneous rate is equal to or greater than the CE currently assigned to the user, then the CE may have become a major factor limiting the rate of the user.
- the base station For non-serving RL users, in order to ensure the neighbor interference control needs, the base station first needs to reserve the minimum number of CEs required to process the control channel for the non-serving RL. Under the premise that the condition is met, the demodulation of the non-serving RL uplink data channel can be dynamically allocated according to the situation of the remaining resources of the base station. The main principle of this dynamic allocation is: If there are any remaining resources, it will be allocated. If there are no remaining resources, it will not be allocated temporarily. If there are remaining resources but there are not enough resources, the allocation can be based on a certain priority rule.
- the base station can transmit the scheduling grant to increase the rate of the user, and for the user of the non-serving RL, the base station can only reduce the rate of the user.
- the base station does not know how the user's serving RL cell is scheduled, so it is not clear how much the user's rate is at the next moment, so no matter how many CEs are allocated to the non-serving RL user, It is possible that the actual CE requirements of the user at the next moment may not be met.
- the CE resources of the serving RL user and the non-serving RL user can be distinguished: When the base station load is heavy, the serving cell user accesses (that is, the user of the serving RL needs to be increased), or the CE that belongs to the serving RL user needs to increase and there is no redundant demodulation resource, the demodulation resource of the non-serving RL user needs to be preempted.
- the CE is fully allocated to the serving RL user, which can improve the throughput of the system.
- the embodiment of the present invention can take the following technical solutions:
- the priority of the non-serving RL allocation demodulation resource is lower than the priority of the service RL allocation demodulation resource.
- dynamically allocate uplink demodulation resources (dynamic allocation mechanism) for the non-serving RL, and demodulate resources for the serving RL user and the non-serving RL user (the specific embodiment may For CE resources) differential processing (preemption mechanism), thus optimizing system performance as a whole.
- the above dynamic allocation mechanism can be set by the system, for example, by the operation and maintenance center OMC.
- OMC operation and maintenance center
- the predetermined mechanism is pre-configured, and the network node configured with the reservation mechanism is notified to other network nodes. Or, configure directly in the base station.
- the configuration in the base station is taken as an example.
- the basis for determining the dynamic allocation mechanism may be one of the following factors or a combination thereof:
- the scheduling priority of the user is a priority based on factors such as user priority and service processing priority. It can be used to distinguish the priority relationship between users.
- the scheduling priority can have multiple levels, such as 1 ⁇ 15.
- the description of the scheduling priority is described by taking only the VIP user and the ordinary user as an example, and it is assumed that the scheduling priority of the VIP user is higher than that of the ordinary user. It can be understood that when multiple RLs are non-serving RLs, the scheduling priority can represent the relative priority of the allocated demodulation resources between the non-serving RLs.
- the specific selective macro diversity combining method may include: the base station determines whether to perform macro diversity and The selective macro is divided into sets, or by selective macro diversity that is transmitted to the base station indicating that the indicator is flexibly implemented.
- a specific example of the macro diversity feature of the user service is as follows: For example, in the macro diversity mode, the feature is "whether the service needs uplink macro diversity", where if a service explicitly indicates Need, even if there are new resources in the future, it is not assigned to the service that explicitly indicates that no allocation is required. For example, in the selective macro diversity mode determined by the base station itself, the feature is "the priority of the uplink macro diversity requirement of the user service". In this way, if a new demodulation resource is available, it can be redistributed. Give the original service to which no demodulation resources are allocated.
- the application of the determining factor may be a comparison between services on the RL in the case of a non-serving RL, or a comparison between services on multiple non-serving RLs.
- the judgment factor it can be set: When the user's service rate is relatively high (such as high-speed upload service), the priority of dynamically allocating demodulation resources is relatively low, and when the user's service rate is relatively low (such as CS voice service) ), its dynamic allocation of demodulation resources has a higher priority.
- the above judgment factors can be used alone. For example, only the user scheduling priority is determined. Moreover, to some extent, the user scheduling priority may also contain information about the service characteristics. For another example, it is relatively simple to implement the macro diversity feature of the user service only in the specific selective macro diversity set mode. For another example, it is judged only by judging the user's business rate.
- the above judgment factors may also be used in combination, and the order of judgment may be scheduled among the above judgment factors. For example, a combination of (1) and (2), and first judge (1), then judge (2). Or other combinations and other order of judgment.
- WCDMA can be used to change the indication of whether the service needs uplink macro diversity by means of RNC reconfiguration (the original MDC is not required, and MDC is required, or vice versa). Change the priority relative relationship of this business.
- the base station increases the priority of the non-serving RL service, which means that the non-serving RL is allocated a demodulation resource.
- the above preemption mechanism can be set by the system, for example, by the operation and maintenance center OMC. After the system is set up, or pre-configured in each network node (such as base station, RNC, E-HSPA in WCDMA, base station in LTE/SAE system, etc.), or in one or several network nodes
- the predetermined mechanism is pre-configured, and the network node configured with the reservation mechanism is notified to other network nodes. Or, configure directly in the base station.
- the principle of the preemption mechanism is: The service RL user preempts the non-serving RL user, and distinguishes the preempted priority within the non-serving RL.
- the judgment of the preemption mechanism may be one of the following factors or a combination thereof:
- the scheduling priority of the user Users with high priority are less likely to be preempted. For example, when the base station is set up for the non-serving RL of the VIP user, because the scheduling priority of the VIP user is relatively high, when the serving cell user accesses and the resources are insufficient, the other non-occupied relative priorities should be preferentially preempted.
- FIG. 1 is a flowchart of a macro diversity set and implementation method of the embodiment.
- Step 101 Establish a data channel and a control channel for the serving radio link RL, and allocate demodulation resources for the data channel and the control channel of the serving RL;
- Step 102 Establish a data channel and a control channel for the non-serving RL, and allocate a demodulation resource for demodulating the control channel for the non-serving RL;
- the base station reserves the minimum number of CEs required to process the control channel for the non-serving RL for the need of neighbor interference control.
- the base station receives the setup request of the non-serving RL initiated by the non-serving RL user.
- the base station first needs to allocate demodulation resources for demodulating the control channel for the non-serving RL.
- the non-serving RL user can be assigned the minimum number of CEs needed to process its non-serving RL control channel.
- control channel used for demodulation may be: an uplink control channel for uplink load estimation, such as a DPCCH (Dedicated Physical Control Channel) and an uplink physical channel E-DPCCH (Enhanced by HSUPA). -Dedicated Physical Control Channel), and a control channel for transmitting the uplink transmit power adjustment indication of the downlink, such as F-DPCH (Forward-Dedicated Physical Channel), and the downlink added by the introduction of HSUPA Physical channel E-RGCH (E-DCH Relative Grant Channel, E-DCH relative to 4 authorized channel).
- an uplink control channel for uplink load estimation such as a DPCCH (Dedicated Physical Control Channel) and an uplink physical channel E-DPCCH (Enhanced by HSUPA).
- E-DPCCH Dedicated Physical Control Channel
- E-DPCCH Enhanced by HSUPA
- E-DPCCH Enhanced by HSUPA
- F-DPCH Forward-Dedicated Physical Channel
- E-RGCH E-DCH Relative Grant Channel, E-DCH relative to 4 authorized channel
- steps 101 and 102 do not have a strict step sequence relationship.
- Step 103 When establishing a non-serving RL, determining whether the demodulation resource currently remaining in the base station is insufficient, if yes, performing step 104; if the demodulation resource is sufficient, executing step 105;
- the remaining demodulation resources are: a demodulation resource allocated to the data channel and the control channel of the serving RL, and a remaining solution of the base station after the demodulation resource is allocated to the control channel of the non-serving RL. Tune resources.
- Step 104 The base station allocates the remaining demodulation resources for the non-serving RL according to the set dynamic allocation mechanism.
- the dynamic allocation mechanism is based on a dynamic allocation priority, where the dynamic allocation priority represents a relative priority of allocation of demodulation resources between different non-serving RLs, and/or between different services carried by non-serving RLs.
- the relative priority of the demodulation resources is allocated.
- the macro diversity feature of the user service is taken as an example to determine a specific selective macro diversity set.
- the selective macro diversity mode is: The uplink selective macro diversity is determined by the base station itself. Since the low-speed CS voice service in the UE service belongs to a service in which the macro diversity requirement has a relatively high priority (the macro diversity gain is relatively large), the demodulation resource is allocated to the CS service and demodulated. Since the demodulation resources are insufficient, and the PS service macro diversity requirement has a lower priority, the demodulation resources are not allocated to the PS service first.
- Step 105 Allocating demodulation resources for the non-serving RLs
- Step 106 If the demodulated resource that is released is available, allocate the available demodulation resource to the service that is not allocated the demodulation resource before the non-serving RL;
- the released demodulation resource may be allocated to the PS service to solve the problem. Tune.
- Step 107 If the resources are insufficient, the service RL performs resource preemption on the non-serving RL according to the set preemption mechanism.
- the preemption mechanism can have multiple possibilities.
- the macro diversity feature of the user service is taken as an example to determine a specific selective macro diversity set.
- step 104 since the priority of the PS service uplink macro diversity requirement is relatively low, the new service RL preferentially preempts the allocation to the PS service.
- the demodulation resource if the resource still cannot satisfy the service RL, then preempts the CS demodulation resource.
- the demodulation resource is not allocated for the PS service in step 103, if the preemption occurs, the demodulation resource of the CS service is directly preempted.
- preemption may also be performed according to other judgment criteria. For example, consider the user's scheduling priority. In the case where there are multiple non-serving RLs at the same time, for example, one is a non-serving RL corresponding to the VIP user, and one is a non-serving RL corresponding to the ordinary user. When the serving cell user accesses and the resources are insufficient, priority should be given. Preempt the demodulation resources of the non-serving RL corresponding to the ordinary user.
- step 106 the two steps can be in no particular order.
- the allocation is again given according to the dynamic allocation mechanism.
- the service (or service data) to which the demodulation resource is allocated is demodulated, and the base station can forward the part of the service to the network node that executes the MDC, and perform macro diversity combining.
- the network node that executes the MDC is an RNC.
- the process can be further divided into the following sub-steps: allocating the data channel demodulation resources, encapsulating the demodulated uplink service data into data frames, and transmitting the encapsulated data frames to the RNC.
- the above-mentioned allocation demodulation resource and the execution subject of the corresponding operation are base stations, and the base station is a non-serving base station for the non-serving RL (for corresponding UE1), but the base station can simultaneously serve as the serving RL (assuming The serving base station of UE2).
- This embodiment is still described by taking a WCDMA system as an example. In this embodiment, it is assumed that it is not in service. Low-speed low-speed VOIP services and high-speed upload services are established on the radio link of the cell. Moreover, the selective macro diversity mode used is: The RNC sets the indication indicator to specify which services require uplink macro diversity.
- the optimization scheme of the MDC is defined in R7, that is, the selective UL MDC scheme and the transmission bearer of the Iub/Iur interface are flexibly implemented based on each MAC-d flow setting indicator carried on the DCH/E-DCH.
- high-speed non-real-time services for uplinks can be set to eliminate the need for MDC (occupying a large amount of transmission resources and the MDC gain is small;), low-speed real-time services such as SRB (Signaling Radio Bearer) and VOIP are set to require MDC.
- the services carried by the DCH channel require UL MDC, and other high-speed non-real-time services do not require UL MDC.
- the SRNC may set the corresponding MAC-d ⁇ ; "Transport Bearer Not Requested Indicator" to be: A: No carry; B: Set to Transport Bearer shall not be Established; C: Set to Transport Bearer may not be Established.
- A is compatible with the traditional mode, B indicates that uplink macro diversity data forwarding is not required, and C indicates that the base station NodeB itself decides whether uplink macro diversity data forwarding is required.
- the non-serving base station NodeB After receiving the indicator (which can be carried in the Radio Link Setup Request message), the non-serving base station NodeB determines whether to establish a lub transmission bearer and forwards the uplink data, and sets the corresponding MAC-d flow of the Radio Link Setup Response to the 'Transport Bearer Not'.
- the Setup Indicator' can be: a: not carried, and assigned the lub transport layer Binding ID and Transport Layer Address; b, set to Transport Bearer Not Setup; where a is compatible with the traditional mode (corresponding to A or C in the request message), b Indicates that the NodeB acknowledges that uplink macrodiversity data forwarding is not required (corresponding to B or C in the request message).
- Step 201 Establish a data channel and a control channel for the serving radio link RL, and allocate a demodulation resource for the data channel and the control channel of the serving RL; This step is the same as the previous embodiment and will not be described again.
- Step 202 Establish a data channel and a control channel for the non-serving RL, and allocate a demodulation resource for demodulating the control channel for the non-serving RL;
- Step 203 The RNC sets a corresponding indicator for the VOIP service and the high-speed upload service, and sends the corresponding indicator to the base station.
- the RNC is assumed to be used for VOIP services: A: No bearer, which indicates that macro diversity is required for VOIP services.
- the method for the high-speed upload service is: Set the corresponding MAC-d i ⁇ "Transport Bearer Not Requested Indicator" to B: Set to Transport Bearer shall not be Established, which means that macro-diversity is not required for high-speed upload service.
- the indicator can be carried in the Radio link Setup Request message and sent to the base station.
- Step 204 The base station allocates the low-speed VOIP service if there is any remaining resources according to the received indicator.
- the base station explicitly knows that the VOIP needs uplink macro diversity according to the received indicator, and the high-speed upload service does not require uplink macro diversity. In this case, if there are remaining resources, they are allocated to the VOIP service.
- Step 205 If the resource is insufficient, the service RL is used to preempt the non-serving RL according to the preset preemption mechanism.
- the demodulation resource allocated for the VOIP service of the non-serving link in step 204 can be preempted.
- step 204 if the high-speed service on the other non-serving link occupies the demodulation resource, it is preferentially preempted by the service link. If the demodulation resources are still insufficient, the demodulation resources allocated in step 204 for the VOIP service of the non-serving link are further preempted. Demodulation resources of non-serving RLs with lower priority.
- the CE allocation method is a fixed allocation method, and user admission is performed according to the Maximum Set of E-DPDCHs, that is, regardless of the actual rate of the user, it is fixedly occupied.
- the uplink rate is greatly improved, and accordingly, the consumption of CE resources is also greatly increased. In this case, the uplink CE resource becomes an affected user. Number and throughput bottlenecks.
- the disadvantages of user admission based on the Maximum Set of E-DPDCHs are: When the user accesses, the RNC performs the admission of the UE according to the "Maximum Set of E-DPDCHs", so that when the number of configurations of the CE is constant, the access is allowed. The number of users is relatively small.
- the RNC can perform user admission according to the Guaranteed Bit Rate (GBR), so that not only the QoS requirements of the user can be reflected, but also according to the Maximum Set of E-DPDCHs. User access can also greatly increase the number of users allowed.
- GBR Guaranteed Bit Rate
- MBR Maximum Bit Rate
- the minimum spreading factor (MTR) is basically corresponding to the MBR. Therefore, the number of CEs corresponding to the MinSF is also greater than the number of CEs corresponding to the GBR. Therefore, user admission according to GBR can greatly increase the number of users allowed. For example, if the total number of CEs sent by the base station is 32, the Maximum Set of E-DPDCHs of the user is configured as 2SF4, and the GBR is configured to 64kbps. If the number of CEs consumed by 2SF4 is 16 CEs, the SF corresponding to 64kbps is SF16, which consumes The number of CEs is two. When the user is admitted according to the Maximum Set of E-DPDCHs according to the prior art, the RNC can only access two such HSUPA users.
- the RNC can enter the 16th. Users.
- the demodulation resource of the data channel uses a dynamic allocation mechanism according to the remaining resources of the current base station.
- the data channel can correspond to the user plane UP
- the control channel can correspond to the control plane CP.
- the CE resources of the serving RL user and the non-serving RL user are differentiated: when the base station load is heavy, the serving cell user accesses, or the CE that belongs to the serving RL user needs to increase and there is currently no redundant demodulation resource,
- the demodulation resources of the non-serving cell users can be preempted, so that the CE is fully allocated to the serving RL users.
- the priority policies used in the above dynamic allocation and preemption mechanisms can be statically configured or dynamically adjusted to suit different network environments and communication requirements.
- the dynamic allocation and preemption of resources according to a certain priority can improve the utilization rate of the uplink demodulation resources, improve the throughput rate of the system, and increase the number of access users. Optimized system performance.
- the simulation results can explain the technical effects of the preemption mechanism: Two scenarios are simulated separately: one is to not occupy the CE of the non-serving RL user; the other is to seize the CE of the non-serving RL user; the simulation is performed in the scenario of the following simulation algorithm model : Wrap-Around scenario, 135UEs, Full Buffer, 128CE/NodeB, simulation results are shown in Table 1. Table 1 System throughput obtained under different strategies
- the process is basically the same, the difference is: (1) the network node performing MDC is the enhanced base station NodeB +; (2) the interface between NodeB + is Iur interface; (3) in the instruction In the case of selective macro diversity, the indicator is sent by the serving cell base station (with SRNC function)
- the difference from WCDMA is: (1) The network node performing the MDC is the evolved base station E-NodeB. (2) The interface between the E-NodeBs is an X2 interface. (3) For LTE/SAE systems, the channel is different from WCDMA.

Description
解调资源分配方法、 基站和系统 技术领域
本发明涉及网络通讯技术领域, 具体涉及一种解调资源分配方法、 基站 和系统。 背景技术
UMTS( Universal Mobile Telecommunications System, 通用移动通信系统 ) 是釆用 WCDMA ( Wideband Code Division Multiple Access, 宽带码分多址接 入)空中接口技术的第三代移动通信系统,通常也把 UMTS系统称为 WCDMA 通信系统。 在 UMTS系统中, 相邻小区的覆盖区域会存在重叠, 利用软切换 可以提供无缝切换, 通过宏分集合并 MDC ( Macro Diversity Combining )所实 现的增益, 可以增加系统的抗干扰能力。
随着移动通信技术的发展, 3G技术也在不断的发展演进。 在 3GPP第 6 版( Release 6, 简称 "R6" )的版本中, 引入了高速上行分组接入 ( High Speed Uplink Packet Access , 简称 "HSUPA" )„ HSUPA同样支持上行宏分集技术。
为了提高 WCDMA 的生命周期和运营商的投资保护, 3GPP 提出了 E-HSPA演进的研究计划, 希望在现有 R6版本的基础上提高频谱效率, 减少 控制面和用户面延迟, 并且能够后向兼容和前向平滑演进到 LTE/SAE (长期 演进计划 /系统架构演进) 系统, 包括空口性能的提升和 RAN ( Radio Access Network, 无线接入网络 )架构的演进。在 E-HSPA( Evolved High Speed Packet Access, 演进的高速分组接入)网络中, RNC (Radio Network Controller, 无 线网络控制器 )功能下移到 NodeB+ ( E-HSPA NodeB, E-HSPA基站)。 NodeB +通过 IuPS接口直接与核心网相连。
在以上通信系统中, 都存在资源分配的问题。 尤其是引入 HSPA 高速业 务后, 提高资源利用率的需求更迫切。
CE ( Channel Element, 信道单元), 是基站的一种资源, 可以看成解调 /
解扩 /解码和编码 /扩频 /调制部分。 CE与业务类型有关, 比如 AMR ( Adaptive Multi-rate, 自适应多速率 ) 12.2k的语音就需要 1个 CE, PS ( acket switched, 分组交换) 64上行需要 4个, 下行需要 2个。现有技术中, CE的分配方式为: 静态分配(或称固定分配)。
在实现本发明的过程中, 发明人发现上述现有技术至少存在如下问题: 不论是引入了 HSUPA的 WCDMA系统或者 E-HSPA,对非服务小区基站 而言, 在 MDC的过程中, 都需要对所有的业务数据分配解调资源。 而在实际 的应用场景中, 对于具有某些业务特性的业务而言 (比如高速非实时业务), 其釆用 MDC的增益并不明显。 这样, 相当于用比较大的解调资源的代价, 换 取了比较小的增益, 就系统整体而言有些得不偿失。
另外, CE静态分配的方法使 CE资源利用的效率低, 从而使得系统的吞 吐率较低。 发明内容
本发明实施方式提供一种解调资源分配的方法、 基站和系统, 在保证邻 区干扰控制的前提下, 按照一定的规则进行解调资源的分配, 可以提高上行 解调资源的利用率, 提高系统的吞吐率, 优化了系统性能。
具体的, 本发明的一个实施例提供了一种解调资源分配方法, 该方法包 括: 为服务无线链路 RL和非服务 RL建立数据信道和控制信道, 并为服务 RL 的数据信道和控制信道分配解调资源, 以及为非服务 RL分配控制信道解调资 源; 在服务 RL和非服务 RL之间分配解调资源, 所述非服务 RL分配解调资源的 优先级低于服务 RL分配解调资源的优先级。
本发明的另一个实施例提供了一种基站, 包括: 建立单元, 用于为服务 无线链路 RL和非服务 RL建立数据信道和控制信道; 第一资源分配单元, 用于 为服务 RL的数据信道和控制信道分配解调资源, 以及为非服务 RL分配控制信 道解调资源; 第二资源分配单元, 用于在服务 RL和非服务 RL之间分配解调资 源, 所述非服务 RL分配解调资源的优先级低于服务 RL分配解调资源的优先
级。
本发明的再一个实施例提供了一种解调资源分配系统, 包括基站实施例 所提供的基站, 以及用户, 所述用户包括非服务无线链路 RL用户以及服务 RL 用户。
通过上述技术方案的描述可知, 本发明实施方式提供的技术方案, 在无 线链路 RL建立时, 非服务 RL数据信道和控制信道都建立, 为控制信道分配解 调资源保证了邻区干扰控制。 在此基础上, 以非服务 RL优先级低于服务 RL为 原则, 在服务 RL和非服务 RL之间分配解调资源。 这样, 可以提高上行解调资 源的利用率, 提高系统的吞吐率, 优化了系统性能。 附图说明
图 1是本发明第一个实施例提供的解调资源分配方法示意图;
图 2是本发明第二个实施例提供的解调资源分配方法示意图;
图 3是本发明第三个实施例提供的基站结构示意图。 具体实施方式
下面结合附图和实施例对本发明实施方式的宏分集合并实现方法进行说 明, 可以理解的是, 本发明实施方式只是举例, 并不用以限制本发明的保护 范围, 本发明的保护范围由权利要求书确定。
本发明实施方式主要以 WCDMA和 E-HSPA系统为例进行说明, 但可以 理解的是, 本发明实施方式提供的技术方案同样适用于 LTE/SAE等系统中。 不同系统中网元的名称有所不同,比如在 WCDMA中无线网络控制器为 RNC , 基站为 NodeB, 在 E-HSPA中基站为增强型基站 NodeB+, LTE系统中为演进 型基站 E-NodeB。 当涉及到宏分集合并 MDC时 , 执行 MDC的网络节点在不 同的系统中为不同的网元, 比如在 WCDMA系统中为 RNC , 在 E-HSPA系统 中为服务小区基站 (增强型基站 NodeB+, 具有服务网络控制器 SRNC功能), LTE系统中为服务小区基站(演进型基站 E-NodeB )。
可以理解的是, HSUPA 釆用 HARQ ( hybrid automatic retransmission request, 混合自动重传请求) 的重传, 而 HARQ的重传导致为了获得相同的 MAC ( Medium Access Control, 媒体接入控制 )层速率, 与 R99相比, 需要 消耗更多的 CE, 所以基站的 CE资源消耗随着 HSUPA的引入而大幅增加。 同时软切换技术也被应用在 HSUPA中, UE与多个小区建立无线链路,对 CE 资源的消耗更大。 综上所述,基站的上行 CE资源会成为影响用户数和吞吐率 的瓶颈。
对于一个基站的 HSUPA用户, 根据其 RL ( radio link, 无线链路) 的属 性可以将其分为两类, 一类是服务 RL的用户, 另一类是非服务 RL的用户。
对于服务 RL的用户, 如果平均速率或即时速率所需要的 CE等于或大于 当前分配给该用户的 CE ,则此时 CE可能已经成为限制用户速率的主要因素。 一方面, 需要增加分配给该用户的 CE; 而另一方面: 为了保证 CE的利用率, 只要增加后的 CE能够满足服务 RL用户业务的需要即可, 即, 不需要为服务 RL用户过多地增加 CE。
对于非服务 RL的用户, 为了保证邻区干扰控制的需要,基站首先需要为 此非服务 RL预留处理控制信道所需的最少 CE数。在满足了该条件的前提下, 此非服务 RL上行数据信道的解调, 可以根据基站剩余资源的情况动态分配。 该动态分配的主要原则是: 如果有剩余资源就分配, 如果没有剩余资源就暂 时不分配。 如果有剩余资源但剩余资源不足, 分配时可以基于一定的优先级 规则。
并且, 根据 3GPP协议 25.309, 对于服务 RL的用户, 基站可以发送调度 授权使用户的速率增加, 而对于非服务 RL的用户,基站只能够让用户的速率 降低。 对于非服务 RL的用户, 基站是不知道用户的服务 RL小区是如何对其 进行调度的, 因此也不清楚下一时刻该用户的速率确切是多少, 因此不论给 非服务 RL用户分配多少 CE, 都有可能不能满足下一时刻用户实际的 CE需 求。 据此, 可以对服务 RL用户和非服务 RL用户的 CE资源进行区别处理:
当基站负载比较重, 服务小区用户接入(即服务 RL的用户需要增加)时或者 属于服务 RL用户的 CE需要增加且当前没有多余的解调资源时, 需要抢占非 服务 RL用户的解调资源, 从而使 CE被充分地分配给服务 RL用户, 可以提 高系统的吞吐率。
据此, 本发明实施例可以釆取如下的技术方案: 非服务 RL分配解调资源 的优先级低于服务 RL分配解调资源的优先级。 具体的, 在保证为服务 RL分 配解调资源的前提下, 为非服务 RL动态分配上行解调资源(动态分配机制), 并且对服务 RL用户和非服务 RL用户的解调资源(具体体现可以为 CE资源) 区别处理(抢占机制), 从而整体上优化了系统性能。
一、 以下首先对动态分配机制进行描述:
上述动态分配机制可以由系统来设定, 比如由操作维护中心 OMC 来设 定。 系统设定好之后, 或者在各个网络节点(比如 WCDMA中的基站、 RNC, E-HSPA以及 LTE/SAE系统中的基站等) 中预先配置该预定机制, 或者在某 个或某几个网络节点中预先配置该预定机制, 再由配置好预订机制的网络节 点告知其他网络节点。 或者, 直接在基站中配置。
以在基站中配置为例进行说明, 动态分配机制的判断依据可以为下列因 素之一或其组合:
( 1 )用户的调度优先级。 用户的调度优先级是根据用户优先级和业务处 理优先级等因素综合出来的一个优先级, 可以用来区分用户之间的优先级关 系, 调度优先级可以有多个等级, 比如 1 ~ 15。 简便起见, 以下涉及调度优先 级的描述时仅以 VIP用户和普通用户为例进行说明, 且假设 VIP用户的调度 优先级高于普通用户的调度优先权。 可以理解的是, 当多个 RL 均为非服务 RL时, 调度优先级可以代表这几个非服务 RL之间的分配解调资源的相对优 先级。
( 2 )特定的选择性宏分集合并方式下, 用户业务的宏分集特性。 所谓特 定的选择性宏分集合并方式, 可以包括: 基站自行决定是否进行宏分集合并
的选择性宏分集合并, 或通过向基站发送指示 indicator灵活实现的选择性宏 分集。 判断特定的选择性宏分集合并方式下, 用户业务的宏分集特性具体举 例如下: 比如, 指示宏分集方式下, 该特性为 "该业务是否需要上行宏分集", 其中, 若某业务明确指示不需要, 即使后续有新的资源, 也不分配给该明确 指示不需要分配的业务。 再比如, 由基站自己决定的选择性宏分集方式下, 该特性为 "用户业务的上行宏分集需求优先级", 这种方式下, 如果有了新的 解调资源可以利用, 还可以再分配给原来给没有分配解调资源的业务。
值得说明的是, 应用该判断因素, 可以是一个非服务 RL情况下, 该 RL 上的业务之间的比较, 也可以是多个非服务 RL上的业务之间的比较。
( 3 )用户的业务速率高低。
应用该判断因素, 可以设定: 当用户的业务速率比较高时 (比如高速上 传业务), 其动态分配解调资源的优先级比较低, 而当用户的业务速率比较氐 时 (比如 CS语音业务), 其动态分配解调资源的优先级比较高。
上述判断因素, 可以单独使用。 比如, 只判断用户调度优先级。 而且, 一定程度上, 用户调度优先级也可能已经包含了业务特性的信息。 再比如, 只判断特定的选择性宏分集合并方式下, 用户业务的宏分集特性, 这种方式 实现起来也相对简单些。 又比如, 只通过判断用户的业务速率高低进行判断。
上述判断因素, 也可以组合使用, 而且, 可以在以上判断因素中排定判 断次序。 比如(1 )和(2 ) 的组合, 且先判断 (1 ), 再判断 (2 )。 或者是其 他组合以及其他判断次序。
值得说明的是, 上述判断因素只是举例, 可以理解的是, 还可以是其他 判断因素。 另外, 该规则也可以动态调整, 以 WCDMA为例, 比如可以通过 RNC 重配置的方式, 将业务是否需要上行宏分集的指示更改(原先不需要 MDC, 改为需要 MDC, 或相反), 以此改变此业务的优先级相对关系。 相应 的, 基站会将此非服务 RL业务的优先级提高, 也就意味着该非服务 RL被分 配解调资源的 ^既率增加。
二、 以下对抢占机制进行描述:
上述抢占机制可以由系统来设定, 比如由操作维护中心 OMC来设定。 系 统设定好之后,或者在各个网络节点(比如 WCDMA中的基站、 RNC, E-HSPA 以及 LTE/SAE系统中的基站等) 中预先配置该预定机制, 或者在某个或某几 个网络节点中预先配置该预定机制, 再由配置好预订机制的网络节点告知其 他网络节点。 或者, 直接在基站中配置。
抢占机制的原则是: 服务 RL用户抢占非服务 RL用户, 在非服务 RL内 部区分被抢占的优先级。
抢占机制的判断依据可以为下列因素之一或其组合:
( 1 )用户的调度优先级。调度优先级高的用户, 其被抢占的几率比较小。 比如, 当基站针对 VIP用户的非服务 RL建立后, 由于此 VIP用户的调度优 先级比较高, 当服务小区用户接入而资源不足的时候, 应该优先抢占其他非 占的相对优先级。
( 2 )特定的选择性宏分集合并方式下, 用户业务的宏分集特性。 与动态 分配机制所适应的是, 容易被分配解调资源的业务, 其被抢占的几率相对较 低。
( 3 )用户的业务速率高低。
上述判断因素, 可以单独使用, 也可以组合使用, 该规则也可以动态调 整。 关于此, 前面已经有所论述, 此处不再赘述。
以下分别举具体实施例, 并结合附图, 对本发明实施方式的技术方案进 行详细描述。
方法实施例一:
该实施例以 WCDMA系统为例进行说明。 本实施例中, 假设在非服务小 区的 RL上建立低速的 CS语音业务(该实施例中简称 CS 业务)和高速的 HSUPA业务(该实施例中简称 PS业务)。并且,釆用的选择性宏分集方式为:
由基站自己决定上行选择性宏分集。 另外, 如果只有一种需要或不需要分配 解调资源的业务, 处理就相对简单, 本发明实施例不对其进行详细描述。 图 1 为本实施例的宏分集合并实现方法流程图。
步骤 101 : 为服务无线链路 RL建立数据信道和控制信道, 并为服务 RL 的数据信道和控制信道分配解调资源;
步骤 102: 为非服务 RL建立数据信道和控制信道, 并为非服务 RL分配 用于解调控制信道的解调资源;
如前所述, 为了保证宏分集合并中, 对于邻区干扰控制的需要, 基站为 非服务 RL预留有处理控制信道所需的最少 CE数。
本步骤中, 基站接收到非服务 RL用户发起的非服务 RL的建立请求, 为 了保证邻区干扰控制的需要,基站首先需要为此非服务 RL分配用于解调控制 信道的解调资源, 即可以为该非服务 RL用户分配满足处理其非服务 RL控制 信道所需要的最少的 CE数。
具体的, 用于解调的控制信道可以为: 用于上行负载估计的上行控制信 道, 比如 DPCCH ( Dedicated Physical Control Channel, 专用物理控制信道 ) 和引入 HSUPA所增加的上行物理信道 E-DPCCH( Enhanced-Dedicated Physical Control Channel增强专用物理控制信道), 以及下行发送用户上行发射功率调 整指示的控制信道, 比如 F-DPCH ( Forward - Dedicated Physical Channel, 前 向专用物理信道 ), 和引入 HSUPA所增加的下行物理信道 E-RGCH ( E-DCH Relative Grant Channel, E-DCH相对 4受权信道)。
对上述控制信道分配解调资源进行解调, 可以有效实现邻区干扰控制。 值得说明的是, 步骤 101和 102没有严格的步骤顺序关系。
步骤 103: 建立非服务 RL时, 判断基站当前剩余的解调资源是否不足, 如果是, 则执行步骤 104; 如果解调资源充足, 则执行步骤 105;
本步骤中, 所述剩余的解调资源为: 为服务 RL的数据信道和控制信道分 配解调资源, 以及为非服务 RL的控制信道分配解调资源之后,基站剩余的解
调资源。
步骤 104: 基站根据设定的动态分配机制, 为非服务 RL分配所述剩余的 解调资源;
本步骤中, 动态分配机制的依据为动态分配优先级, 所述动态分配优先 级代表不同的非服务 RL之间分配解调资源的相对优先级,和 /或非服务 RL承 载的不同业务之间分配解调资源的相对优先级。
如前所述, 该动态分配机制的判断因素可能有多种, 本实施例以判断特 定的选择性宏分集合并方式下, 用户业务的宏分集特性为例进行说明。 本实 施例中, 釆用的选择性宏分集方式为: 由基站自己决定上行选择性宏分集。 由于 UE业务中的低速 CS语音业务属于宏分集需求优先级比较高(其宏分集 增益比较大)的业务, 所以对 CS业务分配解调资源, 对其解调。 由于解调资 源不足, 而 PS业务宏分集需求优先级较低, 所以对 PS业务先不分配解调资 源。
步骤 105: 为非服务 RL全部分配解调资源;
本步骤中, 由于解调资源充足, 则可以为非服务 RL全部分配解调资源。 步骤 106: 如果有被释放的解调资源可以利用, 则将该可以利用的解调资 源分配给非服务 RL之前没有被分配解调资源的业务;
本实施例中, 如果有释放出来的解调资源, 而之前非服务 RL的 PS业务 没有被分配解调资源,所以,可以将该释放出来的解调资源分配给该 PS业务, 对其进行解调。
步骤 107: 如果资源不足, 则根据设定的抢占机制, 实现服务 RL对非服 务 RL的资源抢占。 不同业务之间被服务 RL抢占的相对优先级。 优先级高, 则不容易被抢占。
在非服务 RL连接过程中, 若服务 RL需要新的解调资源且当前没有多余 的解调资源时, 比如, 服务小区用户接入时 (新增服务 RL ) 或者属于服务
RL用户的信道单元 CE需要增加且当前没有多余的解调资源时, 可能造成资 源不足。 如前所述, 该抢占机制可以有多种可能, 本实施例以判断特定的选 择性宏分集合并方式下, 用户业务的宏分集特性为例进行说明。 假设在步骤 103为之前没有分配解调资源的 PS业务分配了 CE,那么在步骤 104中, 由于 PS业务上行宏分集需求的优先级比较低, 则新的服务 RL优先抢占分配给该 PS业务的解调资源, 如果资源仍不能满足服务 RL, 则再抢占 CS解调资源。 当然, 如果在步骤 103中没有为 PS业务分配解调资源, 则如果发生抢占, 则 直接抢占 CS业务的解调资源。
本实施例步骤 107 中, 还可以根据其他判断依据进行抢占。 比如, 考虑 用户的调度优先级。 在同时存在多个非服务 RL的情况下, 比如, 一个是 VIP 用户对应的非服务 RL, —个是普通用户对应的非服务 RL, 则当服务小区用 户接入而资源不足的时候,应该优先抢占普通用户所对应的非服务 RL的解调 资源。
需要说明的是, 以上以步骤 106和步骤 107的形式出现, 但实际上这两 个步骤可以不分先后。 比如, 如果发生抢占之后, 又有被释放的资源可以利 用, 则再次根据动态分配机制给予分配。
可以理解的是, 分配了解调资源的业务(或称业务数据)得到解调, 基 站可以将该部分业务转发给执行 MDC的网络节点, 进行宏分集合并。本实施 例中, 执行 MDC的网络节点为 RNC。 这个过程又可以进一步分为以下子步 骤: 分配数据信道解调资源, 将解调出的上行业务数据封装成数据帧, 将封 装后的数据帧发送给 RNC。
另外, 值得说明的是, 上述分配解调资源以及相应操作的执行主体为基 站, 而该基站对非服务 RL ( 设对应 UE1 )而言是非服务基站, 但该基站可 同时作为服务 RL (假设对于 UE2 ) 的服务基站。
方法实施例二:
该实施例仍以 WCDMA系统为例进行说明。 本实施例中, 假设在非服务
小区的无线链路上建立低速的低速 VOIP业务和高速上传业务。并且,釆用的 选择性宏分集方式为: RNC设置指示 indicator的方式指定哪些业务需要上行 宏分集。
以下先对 RNC指定上行宏分集的方式进行描述:
R7中定义了 MDC的优化方案,即基于 DCH/E-DCH上承载的每个 MAC-d 流设置 indicator来灵活的实现选择性的 UL MDC方案和是否建立 Iub/Iur接口 的传输承载。一般来说,对上行的高速非实时业务可以设置为不需要 MDC(占 用大量传输资源而且 MDC增益小;), SRB (Signaling Radio Bearer, 信令无 线承载 )和 VOIP等低速实时业务设置为需要 MDC。 或者, DCH信道承载的 业务需要 UL MDC, 其他的高速非实时业务不需要 UL MDC。 SRNC可能设 置相应 MAC-d ^;的 "Transport Bearer Not Requested Indicator" 分别可以是: A: 不携带; B: 设置为 Transport Bearer shall not be Established; C: 设置为 Transport Bearer may not be Established。 其中 A兼容传统方式, B表明不需要 上行宏分集数据转发, C表明由基站 NodeB 自己决定是否需要上行宏分集数 据转发。
非服务基站 NodeB接收到上述 indicator后 (可以携带在 Radio link Setup Request消息中)后,判断是否建立 lub传输承载和转发上行数据,并设置 Radio link Setup Response中相应 MAC-d流的 'Transport Bearer Not Setup Indicator' 分别可以是: a: 不携带, 并分配 lub传输层 Binding ID and Transport Layer Address; b, 设置为 Transport Bearer Not Setup; 其中 a兼容传统方式(对应 请求消息中的 A或 C ), b表明 NodeB确认不需要上行宏分集数据转发(对应 请求消息中的 B或 C )。
在上述描述的通过 indicator的方式来实现宏分集的基础上, 参见图 2,本 发明第二个实施例的流程如下:
步骤 201 : 为服务无线链路 RL建立数据信道和控制信道, 并为服务 RL 的数据信道和控制信道分配解调资源;
该步骤和上一个实施例相同, 不再赘述。
步骤 202: 为非服务 RL建立数据信道和控制信道, 并为非服务 RL分配 用于解调控制信道的解调资源;
该步骤和上一个实施例相同, 不再赘述。
步骤 203: RNC针对 VOIP业务和高速上传业务分别设置相应的 indicator, 并发送给基站;
本步骤中, 假设 RNC针对 VOIP业务釆用的方式为: A: 不携带, 即表 明对 VOIP业务需要进行宏分集。针对高速上传业务釆用的方式为: 设置相应 MAC-d i ^ "Transport Bearer Not Requested Indicator"为 B:设置为 Transport Bearer shall not be Established, 即表明对高速上传业务不需要进行宏分集。
该 indicator可以携带在 Radio link Setup Request消息中发送给基站。
步骤 204: 基站根据接收到的 indicator, 如果有剩余的资源则分配给低速 的 VOIP业务;
该步骤中,基站根据接收到的 indicator,明确得知 VOIP需要上行宏分集, 而高速上传业务不需要上行宏分集。 此种情况下, 如果有剩余的资源, 则分 配给 VOIP业务。
步骤 205: 如果资源不足, 则按照设定的抢占机制, 实现服务 RL对非服 务 RL的资源抢占;
本步骤中, 当有服务小区的用户需要接入而解调资源不足时, 则可以抢 占步骤 204中为该非服务链路的 VOIP业务分配的解调资源。
本步骤中, 如果有其他非服务链路上的高速业务占用了解调资源, 则优 先被服务链路抢占。 如果解调资源还不足, 则进一步抢占步骤 204 中为该非 服务链路的 VOIP业务分配的解调资源。 优先级比较低的非服务 RL的解调资源。
后续的步骤, 和上一个实施例类似, 不再赘述。
值得说明的是, 如果在本实施例中, RNC的指示为 C, 即表明由 NodeB 自己决定是否需要上行宏分集数据转发,之后的流程和第一个实施例相同(基 站自行决定), 不再赘述。
基于方法实施例的解调资源的动态分配和抢占机制, 还可以有更优的技 术方案:
比如, 现有技术中, CE的分配方法是固定分配方法, 根据 Maximum Set of E-DPDCHs 进行用户准入, 即不论用户的实际速率是多少, 都固定占用
"Maximum Set of E-DPDCHs" 对应的 CE数。 当上行釆用了上行增强链路进 行数据传输时, 上行的速率得到了大幅度地提高, 相应地, 对 CE资源的消耗 也大幅度地增加, 这种情况下, 上行 CE资源会成为影响用户数和吞吐率的瓶 颈。 而根据 Maximum Set of E-DPDCHs进行用户准入的缺点为: 用户接入时 RNC根据 "Maximum Set of E-DPDCHs " 进行 UE的准入, 这样在 CE的配 置数目一定的情况下, 准入的用户数比较少。
基于此,而本发明实施例的技术方案, RNC可以根据 GBR( Guaranteed Bit Rate, 保证比特率)进行用户准入, 这样, 不仅可以体现用户的 QoS要求, 相比根据 Maximum Set of E-DPDCHs进行用户准入, 还可以大幅度地增加准 入用户数。原因如下: 一般情况, 由于 GBR远小于 MBR ( Maximum Bit Rate, 最大比特率;), 所以 MBR对应的 CE数要大于 GBR对应的 CE数, 而 MinSF
( Minimum Spreading Factor, 最小扩频因子)与 MBR是基本对应的, 因此 MinSF对应的 CE数也要大于 GBR对应的 CE数,所以按照 GBR进行用户准 入可以大幅度地增加准入用户数。 例如: 如果基站下发的 CE总数是 32, 用 户的 Maximum Set of E-DPDCHs配置成 2SF4, GBR配置成 64kbps,如果 2SF4 消耗的 CE数是 16个 CE, 64kbps对应的 SF是 SF16,其消耗的 CE数为 2个, 那么按照现有技术根据 Maximum Set of E-DPDCHs进行用户准入时, RNC只 能准入 2个这样的 HSUPA用户, 而根据 GBR进行用户准入时, RNC可以准 入 16个用户。
综上所述, 本发明实施例提供的技术方案, 无线链路 RL建立时, 非服务 RL数据信道和控制信道都建立, 为保证邻区干扰控制, 为控制信道分配解调 资源。 但是数据信道的解调资源根据当前基站的剩余资源情况, 釆用动态分 配机制。
可以理解的是, 一定程度上, 数据信道可以对应用户面 UP, 控制信道可 以对应控制面 CP。
另外, 对服务 RL用户和非服务 RL用户的 CE资源进行了区别处理: 当 基站负载比较重, 服务小区用户接入时或者属于服务 RL用户的 CE需要增加 且当前没有多余的解调资源时, 可以抢占非服务小区用户的解调资源, 从而 使 CE被充分地分配给服务 RL用户。 而且, 上述动态分配和抢占机制中使用 的优先级策略, 既可以静态配置, 也可以动态调整, 以适应不同的网络环境 和通信需求。
进一步的,可以根据 GBR进行用户准入,从而大幅度地增加准入用户数。 通过以上技术方案, 在保证邻区干扰控制的前提下, 按照一定的优先级 进行资源的动态分配和抢占, 可以提高上行解调资源的利用率, 提高系统的 吞吐率, 增加准入用户数, 优化了系统性能。
仿真结果可以说明抢占机制的技术效果: 分别仿真两种情况: 一种是不 抢占非服务 RL用户的 CE; 另外一种是抢占非服务 RL用户的 CE; 在下述仿 真算法模型的场景下进行仿真: Wrap-Around 场景, 135UEs, Full Buffer, 128CE/NodeB, 仿真结果如表 1所示。 表 1 不同策略下获得的系统吞吐率
从表 1可以看出当抢占非服务 RL用户的 CE后, 系统的吞吐率从 7.82M
增加到 18M, 改善非常显著。
以上实施例主要以 WCDMA系统为例进行说明, 可以理解的是, 本发明 实施例的技术方案, 同样适用于其他支持软切换和上行宏分集的无线网络中, 比如 E-HSPA扁平架构。
如果是 E-HSPA, 那么, 流程大体相同, 不同之处在于: (1 )执行 MDC 的网络节点为增强型基站 NodeB +; ( 2 )NodeB +之间的接口为 Iur接口; (3 ) 在指令选择性宏分集的情况下, 由服务小区基站 (具有 SRNC 功能)发送 indicator„
另外 , 如果在 LTE/SAE系统仍然保留 MDC功能 , 则和 WCDMA不同之 处在于: ( 1 )执行 MDC的网络节点为演进型基站 E-NodeB。 ( 2 ) E-NodeB之 间的接口为 X2接口。 ( 3 )针对 LTE/SAE系统, 信道和 WCDMA中不同。
本发明实施例还提供了一种基站, 图 3 为本发明实施例提供的基站结构 示意图。
该基站包括: 建立单元 301 , 用于为服务无线链路 RL和非服务 RL建立 数据信道和控制信道; 第一资源分配单元 302, 用于为服务 RL的数据信道和 控制信道分配解调资源, 以及为非服务 RL分配控制信道解调资源; 第二资源 分配单元 303 , 用于在服务 RL和非服务 RL之间分配解调资源, 所述非服务 RL分配解调资源的优先级低于服务 RL分配解调资源的优先级。
对于服务 RL的用户, 建立单元 301为其建立数据信道和控制信道, 第一 资源分配单元 302为服务 RL的数据信道和控制信道分配解调资源。
为了保证宏分集合并中,对于邻区干扰控制的需要,基站为非服务 RL预 留有处理控制信道所需的最少 CE数。 当基站接收到非服务 RL用户发起的非 服务 RL的建立请求时, 第一资源分配单元 302为此非服务 RL分配用于解调 控制信道的解调资源, 即可以为该非服务 RL用户分配满足处理其非服务 RL 控制信道所需要的最少的 CE数。在此基础上, 第二资源分配单元 303根据基 站的解调资源(CE资源)情况, 在服务 RL和非服务 RL之间分配解调资源。
为实现动态分配, 基站还可以包括: 第一存储单元 304, 用于存储非服务 RL的解调资源动态分配机制, 所述动态分配的依据为动态分配优先级, 所述 动态分配优先级代表不同的非服务 RL之间分配解调资源的相对优先级, 和 / 或非服务 RL承载的不同业务之间分配解调资源的相对优先级。 与此相适应, 第二资源分配单元 303 可以进一步划分为: 第一判断子单元, 用于建立非服 务 RL时, 判断基站剩余的解调资源是否不足, 所述剩余的解调资源为: 为服 务 RL的数据信道和控制信道分配解调资源, 以及为非服务 RL的控制信道分 配解调资源之后, 基站剩余的解调资源; 分配子单元, 用于当所述第一判断 子单元的判断结果为是时,按照所述存储单元 304所存储的非服务 RL的解调 资源动态分配机制, 为所述非服务 RL分配所述剩余的解调资源。 当然, 若没 有剩余的解调资源, 则不分配。 可以理解的是, 建立非服务 RL的时候, 对分 配给服务 RL的解调资源没有影响, 即非服务 RL优先级低于服务 RL; 而有 剩余的解调资源而又不足时, 则需要根据设定的动态分配优先级, 为非服务 RL分配剩余的解调资源。 具体分配的过程在方法实施例中已经有了比较详细 的描述, 此处不赘。
为实现服务 RL对非服务 RL的抢占,基站还可以包括:第二存储单元 305, 用于存储服务 RL对非服务 RL的抢占机制, 所述抢占机制的依据为抢占优先 和 /或非服务 RL承载的不同业务之间被服务 RL抢占的相对优先级。与此相适 应的是, 所述第二资源分配单元包括: 第二判断子单元, 用于在非服务 RL建 立过程中, 判断是否有新的服务 RL或服务 RL需要新的解调资源且当前没有 多余的解调资源; 抢占子单元, 用于当所述第二判断子单元的判断结果为是 时, 根据第二存储单元所存储的抢占机制, 抢占非服务 RL的解调资源, 并将 抢占的解调资源分配给服务 RL。 具体抢占的过程在方法实施例中已经有了比 较详细的描述, 此处不赘。
另外, 该基站还包括准入单元, 用于根据保证比特率进行用户准入。 这
样, 可以大幅度地增加准入用户数。

另外, 该系统中还可以包括执行宏分集合并的网络节点, 所述网络节点 为无线网络控制器 RNC, 或增强型基站 NodeB +; 或演进型基站 E-NodeB。
上述实施例中提供的基站和系统, 涉及的技术特征所带来的技术效果在 方法实施例中已经做了比较详细的描述, 此处不赘。
本领域普通技术人员可以理解实现上述实施例方法携带的全部或部分步 骤是可以通过程序来指令相关的硬件完成, 所述的程序可以存储于一种计算 机可读存储介质中, 该程序在执行时, 包括如下步骤: 为服务无线链路 RL和 非服务 RL建立数据信道和控制信道, 并为服务 RL的数据信道和控制信道分 配解调资源, 以及为非服务 RL分配控制信道解调资源; 在服务 RL和非服务 RL之间分配解调资源, 所述非服务 RL分配解调资源的优先级低于服务 RL 分配解调资源的优先级。
另外, 在本发明各个实施例中的各功能单元可以集成在一个处理模块中, 也可以是各个单元单独物理存在, 也可以两个或两个以上单元集成在一个模 块中。 上述集成的模块既可以釆用硬件的形式实现, 也可以釆用软件功能模 块的形式实现。 所述集成的模块如果以软件功能模块的形式实现并作为独立 的产品销售或使用时, 也可以存储在一个计算机可读取存储介质中。
