Description

态QoS控制的方法及装置 A method and apparatus for QoS control state

技术领域 FIELD

本发明涉及UMTS (Universal Mobile Telecommunications System,通用移动通信系统),尤其指在UTRAN (UMTS Terrestrial Radio Access Network, UMTS地面无线接入网)的基站调度中实现动态QoS控制的方法及装置。 The present invention relates to UMTS (Universal Mobile Telecommunications System, Universal Mobile Telecommunications System), especially of (UMTS Terrestrial Radio Access Network, UMTS Terrestrial Radio Access Network) base station scheduling method and apparatus for dynamic QoS control is implemented in UTRAN.

背景技术 Background technique

UTRAN由用户设备(UE)、基站(Node B)和RNC (Radio network controner, 无线网络控制器)组成,无线接口(UE-UTRAN)的协议结构分为物理层、数据链路层;RNC负责对各种接口的管理,承担无线资源管理(RRM) ; Node B 是受RNC控制,完成RNC与无线信道之间的编码转换,实现无线接口与物理层间的相关处理如无线信道编码、交织、速率匹配和扩频等,在R6 (release 6,第6版本),如增强型专用传输信道E-DCH中负责上行的分组调度功能。 UTRAN consists of a user equipment (the UE), the base station (Node B) and RNC (Radio network controner, a radio network controller), with a wireless interface (UE-UTRAN) protocol architecture is divided into a physical layer, a data link layer; the RNC is responsible for various management interfaces, assume radio resource management (RRM); Node B is controlled by the RNC, transcoding is completed between the RNC and the radio channel, realized between the processing associated with the physical layer as radio interface radio channel coding, interleaving, rate spreading matching and the like, R6 (release 6, version 6), such as the enhanced dedicated transport channel E-DCH for uplink in the packet scheduling function.

数据链路层包括两个子层,即:MAC (Medium Access Control,媒体接入控制)层和RLC (Radio Link control,无线链路控制)层,在MAC层中执行为RLC层提供的逻辑信道与物理层提供的传输信道之间的映射,并根据逻辑信道的资源速率为每个传输信道选择合适的传输格式(TF)。 The data link layer comprises two sub-layers, namely: MAC (Medium Access Control, media access control) layer and a logical channel RLC (Radio Link control, radio link control) layer, it is performed in the MAC layer and the RLC layer provides mapping between the transport channel by the physical layer, and select the appropriate transport format (TF) for each transport channel according to the resource rate of a logical channel.

在UTRAN中定义了四种基本业务类型:会话类业务、流类业务、交互类业务、后台类业务,并且当UMTS为每一业务类提供载体服务时需要保持QoS(Quaiity Defines four types of basic service in UTRAN: session services, streaming class traffic, interactive traffic class, background class traffic, and when a UMTS bearer service provides for the need to keep each traffic class QoS (Quaiity

of Service,月艮务质量)。 of Service, Quality of Service February Burgundy).

通常,QoS通常可以由可测量的参数来表征:(1)发送和接受的时间间隔一时延;(2)网络中业务的传输速率;(3)丢包率;(4)业务有效性。 Typically, QoS can generally be characterized by measurable parameters: (1) sending and receiving a delay time interval; (2) the transmission rate of the network traffic; (3) packet loss rate; (4) availability of service.

在当前UTRANR6中引入了用于对上行分组域的数据速率进行增强、改善用户体验的HSUPA (High speed uplink packet access ,高速上行分组接入)。 It introduces HSUPA data rate for the uplink packet domain enhanced, improving the user experience in the current UTRANR6 (High speed uplink packet access, HSUPA). 对分组业务的QoS的支持直接影响HSUPA的应用,3GPP定义了基于RNC的QoS控制机制, 但是这种相对静态或准静态的控制大大影响了无线资源的利用效率。 Support for packet service QoS directly affect the application of HSUPA, 3GPP defines the RNC based QoS control mechanism, but this is relatively static or quasi-static control greatly affect the efficiency of radio resources. 另外,当分组调度功能在Node B上时,在调度器中增强QoS的控制可以在提高资源的利用效率的同时更好地保证业务的QoS。 Further, when the packet scheduling function at the Node B, enhanced QoS control in the scheduler may be better guarantees QoS while improving the utilization efficiency of resources. 然而,因为NodeB仅仅有有限的业务QoS信息,如何在调度器实现QoS控制一直是NodeB调度器研究的重点和难点。 However, since there are only limited business NodeB QoS information, how to achieve the scheduler QoS control it has been the focus and difficulty NodeB scheduler research.

HSUPA中采用了基于NodeB (基站)的调度的策略,并随之在基站和终端中引入了相应的上、下行信令来支持该策略。 HSUPA adopts a strategy based on the NodeB (base station) scheduling, and subsequently introduced into the corresponding uplink and downlink signaling in the base station and the terminal to support the policy.

与调度过程相关的HSUPA的上行命令包括在E-DPCCH (增强型专用控制信道)中传输的满意度比特(Happybit)。 HSUPA scheduling process associated with the command included in the uplink E-DPCCH (Enhanced Dedicated Control Channel) transmitted satisfaction bits (Happybit).

与调度过程相关的下行信令主要包括用于逐步调整用户资源的相对命令(RG, Relative Grant)。 Scheduling related downlink signaling procedure including a command for stepwise adjustment of the relative user resources (RG, Relative Grant).

目前3GPP标准化组织定义了以下方法在HSUPA (或E-DCH)中实现分布式的QoS控制: Currently the 3GPP standardization organization defines the QoS control method implemented in a distributed HSUPA (or E-DCH) in which:

方法之一,在UE中通过E-TFC (传送格式组合)选择进行优先级速率调 One way, in the UE prioritizes rate adjusted by E-TFC (transport format combination) selection

度; degree;

方法之二,在RNC中通过区分非调度传输(NST)和调度传输(ST)的配置以及通过外环功率控制(Outer Loop Power Control)来调节基准E-TFCI (传送格式组合指示)和每MAC-d流的HARQ( Hybrid automatic retransmission request ,混合自动重传请求)的属性文件(profile)来实现的。 The second method, in the RNC to adjust the reference E-TFCI (Transport Format Combination Indicator), and to distinguish each non-scheduled transmission by MAC (NST) and the scheduled transmission (ST) and by the configuration of outer loop power control (Outer Loop Power Control) HARQ (hybrid automatic retransmission request, hybrid automatic repeat request) -d flow properties of the file (Profile) to achieve.

然而,对于方法一,在基于UE的ETFC选择中,仅考虑逻辑信道的优先级。 However, a method for, based on the UE ETFC selection, considering only priority logical channel. 该方法虽然区别了相对的优先级,但是没有从根本上保证服务的QoS信息如延迟。 This method, although the difference between the relative priorities, but there is no guarantee QoS information services such as the delay fundamentally.

对于方法二,在RNC中与E-DCH (Enhanced dedicate channel,增强专用传输信道)相关的RRM中,通过设置每MAC-d流的HARQ属性来调节QoS的控制, 然而该控制QoS的方法只是很好地控制了HARQ的重传特性,间接在调度器中引入QoS控制,可以很好地控制丢包率和平均重传次数,但是无法较好地控制诸如等待延迟和最小比特速率的业务QoS,另外基于RNC的控制方法有比较大的延迟。 A method for the second method in the RNC and E-DCH (Enhanced dedicate channel, enhanced dedicated transport channel) associated RRM, the adjusted QoS control by setting HARQ attributes of each MAC-d flow, whereas the QoS control it is very better control the characteristics of the HARQ retransmission, the indirect introduction of QoS control in the scheduler, can be well controlled packet loss rate and average number of retransmissions, but not as well-waiting service QoS control delay and minimum bit rate, Further a relatively large delay in the RNC control method. 另外,如果通过将服务映射到NST上,将会浪费了小区资源,因为基站调度并不负责NST上业务的调度。 In addition, if the service mapped to by NST, community resources will be wasted, because the base station scheduling NST is not responsible for the scheduling service. 仅支持RNC 中所配置的参数进行调度,应该说在当前基站控制的调度器中还没有完善的处理业务QoS的方案。 Parameter only supports the RNC configured to schedule, it should be said that in the current control of the base station scheduler no sound processing service QoS scheme.

基于在3GPP TR25.896关于增强UTRA FDD上行链路的可行性研究中指出的, 通过使用基站控制的调度器可以使系统性能(如小区通过量、延迟)改善50〜70%, 因此应该减少使用非调度传输支持服务的QoS方法,加强基站调度器对QoS支持可以扩大可调度的分组业务范围,从而实现系统性能的提高。 Based indicated in 3GPP TR25.896 Feasibility study for enhanced uplink in UTRA FDD, by using the base station scheduler may control the performance of the system (e.g., cell throughput, delay) improve 50~70%, and should reduce the use of QoS support method of non-scheduled transmission service, to strengthen the base station scheduler may schedule QoS support can be extended to packet service range, thereby achieving improved system performance.

本发明正是在上述的技术背景下,提出了用于HSUPA的基站调度中实现动态QoS控制的方法及装置的技术方案。 The present invention is in the above-described technical background, a base station for scheduling in HSUPA achieve dynamic QoS control technique of the method and apparatus.

综上所述,基站中的动态QoS控制特点和优点: In summary, the base station dynamic QoS control features and advantages:

基站中的动态QoS控制进一步增强了一基站调度器对分组业务的支持,可以避免E-DCH的太多NST (非调度传输)配置,其改善了资源分配效率(由于NST属于非调度,在资源使用上比较保守)。 Dynamic QoS control of base stations a base station scheduler further enhanced support for packet services, E-DCH can be avoided too NST (non-scheduled transmission) configuration, which improves the efficiency of resource allocation (since the NST is non-scheduling resources use the more conservative). 其中,支持速率控制的基站调度器可以统计意义上控制E-DCH上的优先级服务的数据速率,同时两级动态的速率控制作用于实际应用以保证快速响应;而支持延迟控制的基站调度器,可以关注到部分具有QoS需求服务的延迟情况,充分利用S_RG (服务RG命令)来快速动态地调整资源的分配来满足分组业务的需求。 Wherein the base support rate control scheduler may control the data rate of the priority service on the E-DCH in a statistical sense, while the two dynamic rate control applied to practical applications in order to ensure rapid response; the support of the base station scheduler delay control We are concerned about the delays in the demand for services with QoS section, make full use of S_RG (RG service command) to quickly adjust dynamically allocate resources to meet the needs of packet services.

因此,本发明方案使得HSUPA基站调度器能进行QoS控制而不是通过RNC的控制来相应地保持QoS (实际操作在RNC中进行控制),并在基站的动态QoS控制中,HSUPA可以更好地支持作为分组业务需求的QoS。 Accordingly, the present invention enables the base station HSUPA scheduler can perform the QoS control rather than holding a corresponding QoS (the actual control of the operation in the RNC), and a dynamic QoS control in the base station, HSUPA can be better controlled by the RNC supports as packet traffic QoS requirements.
