无线移动通信系统的资源管理方法及切换方法 Resource management method and a switching method for a wireless mobile communication system

技术领域 FIELD

[0001] 本发明涉及通信领域,尤其涉及无线移动通信系统的资源管理方法及切换方法, 特别是有关于演进移动通信系统的资源管理方法及切换方法。 [0001] The present invention relates to communication field, in particular, resource management, and relates to a handover method of a wireless mobile communication system, the resource management method and particularly relates to a handover method in a mobile communication system evolved.

背景技术 Background technique

[0002] 近年,移动通信技术发展得很快。 [0002] In recent years, mobile communication technology developed rapidly. 在这个过程中,第二代移动通信标准起到了至关重要的作用,但现在的无线移动通信只能够为用户提供电话服务和低速率的数据服务。 In this process, the second generation mobile communication standard plays a crucial role, but only wireless mobile communications to provide users with telephony services and low rate data services. 随着hternet在全球的空前普及,Internet多媒体技术和通信技术的融合已经成为未来移动通信技术的发展趋势。 With hternet unprecedented popularity in the world, Internet multimedia convergence technology and communication technology has become the development trend of future mobile communication technology. 为了满足移动用户不断增长的业务需求,移动电信业开始积极研究和部署第三代移动通信系统,未来将能够为用户提供多媒体、分组交换和宽带移动访问等新的服务,这就是所谓的第三代全球移动通信系统。 In order to meet the growing business of mobile users demand, mobile telecommunications industry began to actively research and deployment of third-generation mobile communications system, the future will be able to provide users with multimedia, new services and broadband packet-switched mobile access, which is called the third on behalf of the global system for mobile communications. 随着第三代移动通信技术的发展,网络规划和优化工作越来越重要。 With the development of third generation mobile communication technology, network planning and optimization and more important. 网络优化的目的是改善对用户的服务质量,提高网络资源的利用率。 Network optimization is to improve the quality of service to users, improve the utilization of network resources. 因此,需要寻找有效的无线资源管理方案来管理系统的可用资源,以满足用户容量的不断增加。 Therefore, the need to find effective radio resource management program to manage the available resources of the system to meet increasing subscriber capacity. 无线资源管理一般包括切换控制、功率控制、接纳控制、负载控制等。 Generally include radio resource management handover control, power control, admission control, load control and the like.

[0003] 在现有的第三代无线移动通信系统的无线资源管理策略中,为了使掉话率限制在某一阈值范围内,通常在每个小区的基站上为预接纳的切换用户预留一定的资源。 [0003] In the conventional radio resource management strategies third generation wireless mobile communication system, in order to limit the rate of dropped calls within a certain threshold range, usually reserved for receiving the pre-handover users at the base station of each cell certain resources. 该资源的使用准则是一一只有切换用户有权使用这部分资源,而新接入的用户不能使用。 Guidelines for the use of the resource is only eleven switching users have access to this part of the resources, and the new access users can not use. 这种预留资源的资源管理方式虽然可提升切换用户的切换成功率,但降低了资源的使用效率,同时也加大了新接入用户被拒的可能性。 This reserve resources management of resources, although the handover success rate can be improved to switch users, but reduces the efficiency of resource use, but also increased the likelihood of new users access declined.

[0004] 另外,在现有的第三代无线移动通信系统的切换控制时,当用户切换至目标小区时,目标小区需要依据预接纳的用户的QoS(服务质量)、该小区的剩余可用资源的情况以及小区当前服务用户的QoS等进行整体调度分配预接纳切换用户的资源。 [0004] Further, when the switching control conventional third generation wireless mobile communication system, when a user switches to a target cell, the target cell needs to be based QoS (Quality of Service), the remaining available resource of the cell receiving the user's pre- as well as the current serving cell of the user's QoS, the overall receiving scheduling assignment of resources pre-handover users. 在切换过程中需要完成上述分配资源,增加了切换过程所占用的时间,同时也增加了用户掉线的概率。 In the switching process requires completion of the allocation of resources, increase the switching process takes time, but also increases the probability of users dropped.

[0005] 以TD-SCDMA系统为例,其网络构架如图1所示:该系统由CN(核心网)、UTRAN(无线接入网)和UE (用户终端)三部分组成。 [0005] In TD-SCDMA system as an example, the network architecture shown in Figure 1: The system consists CN (Core Network), the UTRAN (radio access network) and a UE (user terminal) of three parts. CN与UTRAN的接口为Iu接口,UTRAN与UE的接口为Uu接口。 CN and UTRAN Iu interface is an interface, the interface UTRAN Uu interface to the UE.

[0006] 如图2所示,UTRAN包括许多通过Iu接口连接到CN的RNS (无线网络系统)。 [0006] As shown in FIG 2, UTRAN comprises a plurality of the RNS (radio network system) is connected to the CN via the Iu interface. 一个RNS包括一个RNC (无线网络控制器)和一个或多个Node B (基站)。 A RNS comprises a RNC (radio network controller) and one or more Node B (base station). Node B通过Iub 接口连接到RNC上。 Node B connected to the RNC through the Iub interface.

[0007] 在TD-SCDMA系统的每个RNC中,通常通过RRM(无线资源管理器)进行资源的管理。 [0007] In the TD-SCDMA system, each of the RNC, the resource management is generally carried out by the RRM (Radio Resource Manager). 所述资源管理包括资源的分配、重配、资源释放等。 Said resource manager comprises a resource allocation, reconfiguration and releasing resources. RRM为每个小区预接纳的切换用户预留一部分资源,并且这部分资源只有预接纳的切换用户才有权使用,新接入的用户无使用。 Receiving for each cell pre-RRM switch user part of the resources reserved, and this is only part of the resources of the pre-switch user receiving the right to use, without the use of the new access users. 当用户发起接入请求时,是以子带为基本资源给该用户分配资源,所述资源包括其频率资源和时隙资源。 When a user initiates an access request, the sub-band is the basic resource allocating resources to the users, the resources include frequency resources and time slot resources. 由于每个RNC下辖多个NodeB,每个NodeB存在多个用户,因此RRM的负担较重。 Because each jurisdiction plurality RNC NodeB, NodeB each of the plurality of users, and therefore heavier burden RRM. 并且,每一小区需要给切换用户预留资源,这一部分资源的利用率低且加大新接入用户被拒的可能性。 And each cell need to switch the user to reserve resources, the possibility that part of the resource utilization rate and increase new user access rejected. [0008] 当用户与NodeB通话过程中,由于用户的移动等其它原因用户可能会离开这个小区的服务范围,此时就需要通过切换过程将用户的连接切换至其它小区,致使通信服务不中断。 [0008] and the NodeB call when the user, since the user of a mobile user such other reasons may be out of the service range of the cell, in which case the user will need to handover to another cell is connected by the handover procedure, so that the communication service is not interrupted. 切换过程简述如下:首先,RNC定时接收UE上报的测量结果,根据该测量结果可以进行是否实施切换准则的判定,若是满足切换条件,则确定目标小区;然后,RNC可以将服务小区上报的UE位置信息及其它相关信息传送至目标小区;随后,目标小区需要依据预接纳的用户的QoS (服务质量)、该小区的剩余可用资源的情况以及小区当前服务用户的QoS等进行整体调度分配预接纳切换用户的资源;最后,用户与目标小区同步后,执行切换。 A handover procedure are summarized as follows: Firstly, the timing of the RNC receives a measurement result reported by the UE may be determined whether to perform handover based on the measurement criteria, if the handover condition is satisfied, it is determined that the target cell; Then, the RNC serving cell may be reported by the UE location information and other relevant information to the target cell; subsequently, the target cell is required overall scheduling assignment based on QoS (quality of service), where the remaining available resources in the cell and the cell currently serving the user's QoS user pre receiving the like pre-admission switch user resources; Finally, the synchronization with the target cell after the user performs switching. 上述切换过程需要为预接纳切换用户分配资源,此过程增加切换时延。 The switching process requires the user to pre-allocate resources to receive the handover, this process increases the handover delay.

6场计算UE所需的资源而是使用UE原有的资源相关配置参数。 6 games computing resources required UE UE but the use of existing resources related configuration parameters. 这样,可以加快目标E-Node B的资源预备过程,提高整个切换过程的速度。 Thus, resources can accelerate the preliminary process of the target E-Node B, to improve the speed of the whole handover procedure.

[0047] E-Node B :在完成3G系统中Node B基本功能(譬如,无线接口物理层协议的处理)之外,还独立承担E-Node B自身无线资源管理的相关功能,譬如:资源分配与整合、 接纳管理、拥塞管理、通信链路监控、数据包调度以及功率控制、E-Node B下不同小区间切换的控制等功能,即与多小区管理和网络密切相关的无线资源管理功能由CPS为主完成, 而E-Node B独立完成与自身资源和特性密切相关的无线资源管理功能。 [0047] E-Node B: Node B basic functions (for example, the radio interface physical layer protocol processing) is completed in the 3G system, but also independently undertake related functions E-Node B own radio resource management, such as: a resource allocation and control functions to switch between different cells of the integration, the receiving management, congestion management, monitoring the communication link, a data packet scheduling and power control, E-Node B, that is closely related to the multi-cell radio resource management and network management functions performed by CPS mainly completed, and the E-Node B independently is closely related to their own resources and characteristics of the radio resource management functions. 其次,为了提升RAN(无线接入网络)系统对于无线信道时变特性的适应能力,E-Node B和UE之间通过HARQ(混合自动重传)技术编码和调制技术的自适应性选择。 Secondly, in order to enhance the RAN (radio access network) system adaptability for varying characteristics of the wireless channel between the UE and the E-Node B by HARQ (hybrid automatic retransmission) selection techniques adaptive coding and modulation techniques. 为了消除HARQ遗留的传输数据错误,E-Node B的高层协议中含有外层重传机制。 In order to eliminate the remaining HARQ data transmission error, E-Node B contains high-level protocol layer retransmission mechanism. 为了进行高效率的无线资源管理, E-Node B还完成对UE测量的控制。 In order to perform efficient radio resource management, E-Node B also complete control of UE measurements.

[0048] E-Node B通过IP网络与Evolved CN直接建立连接,也就是说,系统中的用户面只有Evolved CN和E-Node B两个节点。 [0048] E-Node B via the IP network to establish a direct connection Evolved CN, i.e., the system user plane only Evolved CN and two E-Node B Node. 在控制面中,E-Node B独立承担的自身无线资源管理功能的信令部分与Evolved CN直接连接,完成业务的建立、保持和释放功能。 In the control plane signaling portion, E-Node B itself sole radio resource management functions directly connected to the Evolved CN, to complete the establishment of business, maintaining and releasing functions.

[0049] CPS和Evolved CN之间通过Iu'接口连接,CPS发起的数据链路转接请求以及MBMS、网络共享以及KPI参数提取等与Evolved CN之间的交互均经由此接口发送。 [0049] The interface between the CPS and Evolved CN via Iu ', the interaction between the data link Evolved CN initiates the transfer request CPS and MBMS, and network sharing KPI extraction parameters are transmitted via this interface.

[0050] CPS和E-Node B之间通过Icn接口连接,E-Node B向CPS提供UE测量中与多小区管理相应的测量报告,以及实时向CPS上报自身的资源状况和处理负荷状况。 [0050] between the CPS and the E-Node B through the interface Icn, E-Node B provides corresponding measurement report with the multi-cell UE measures to CPS management, and real-time status report its own resources and the processing load status of the CPS. CPS在UE 测量报告和E-Node B资源状况和处理负荷信息的基础上,依据RRM(无线资源管理)策略进行UE的切换判决与控制。 CPS based on UE measurement reports and the E-Node B resource status information and processing load on the UE handover decision and control according to the RRM (Radio Resource Management) strategy. 同时,CPS中MBMS、网络共享KPI参数等控制信息也经由此接口下达给E-Node B。 Meanwhile, CPS in MBMS, the network sharing KPI parameters control information via this interface are also issued to the E-Node B. 切换过程所需的UE Context (UE上下文)也经由此接口下传至目标E-Node B0 E-Node B进行无线资源管理过程中使用的算法以及相关参数也由CPS来设定和变更。 Handover procedure required UE Context (UE context) is also transmitted to the target E-Node B0 E-Node B via the interface algorithm and thus the parameters related to the radio resource management procedures are also used to set and changed by the CPS.

[0051] CPS之间的Icc接口,用于辅助CPS完成跨CPS的UE切换控制。 [0051] Icc interface between the CPS, to assist complete CPS UE handover control across the CPS.

[0052] E-Node B之间的Irm接口,用于为支持无损切换所需的前传数据提供数据通道。 [0052] Irm interface between E-Node B, for providing a data path for forwarding data to support lossless handover required.

[0053] 根据实际应用需要,系统广播功能的控制可以在Evolved CN或者CPS实体上完成,也可以直接由E-Node B来控制。 [0053] depending on the application, system control broadcast functions may be done on Evolved CN or CPS entities may be directly controlled by the E-Node B.

[0054] Evolved CN也可以不和CPS连接,直接和E-NodeB连接。 [0054] Evolved CN CPS and may not be connected, and the E-NodeB directly connected. 请参照图!3B,其为另一种演进无线通信系统的网络架构示意图。 Referring to FIG! 3B, which is a schematic diagram of an evolved network architecture wireless communication system to another. E-Node B通过IP网络与Evolved CN直接建立连接, 也就是说,系统中的用户面只有Evolved CN和E-Node B两个节点。 E-Node B via the IP network to establish a direct connection Evolved CN, i.e., the system user plane only Evolved CN and two E-Node B Node. 在控制面中,E-Node B 独立承担的自身无线资源管理功能的信令部分与Evolved CN直接连接,完成业务的建立、 保持和释放功能以及切换决策和执行。 In the control plane signaling portion, E-Node B itself sole radio resource management functions directly connected to the Evolved CN, complete business establishment, maintenance and release function and a handover decision and execution. 同时,E-Node B有关的MBMS、网络共享、系统广播控制以及KPI参数提取等功能相关信息也经由此接口与Evolved CN进行交互。 Meanwhile, the relevant MBMS E-Node B, a network share, and KPI control system broadcast parameter extraction functions relevant information via this interface also interact with Evolved CN.

[0055] CPS主要为其下辖的E-Node B提供各个小区无线资源管理信息和多小区管理策略,在E-Node B需要切换时为其选出合适的目标小区及伴随的目标E-Node B。 [0055] CPS mainly under the jurisdiction of its E-Node B provides radio resource management information of each cell and multi-cell management strategies, in the E-Node B need to switch to its appropriate target cell is selected and the associated target E-Node B.

[0056] 正交频分复用(OFDM)技术是一种多载波数字通信技术,它由多载波调制(MCM)技术发展而来,其显著特点是其利用的各子载波均为相互正交的。 [0056] Orthogonal Frequency Division Multiplexing (OFDM) technology is a multi-carrier digital communications technology, which (MCM) technology developed from multi-carrier modulation, and its distinguishing feature is the use of each subcarrier are orthogonal to each other of. 该技术的基本原理是将高速串行数据变换为多路相对低速的并行数据并对不同的载波进行调制。 The basic principle of this technique is the high-speed serial data into multiple relatively low-speed parallel data and modulates a different carrier. 上述公开的演进移动通信系统使用OFDM技术进行数据传输,为了获得较高的频谱使用效率,期望使用尽量小的频率复用系数。 Disclosed above evolved mobile communication system using OFDM techniques for data transmission, in order to obtain high spectral usage efficiency, it is desirable to use the smallest possible frequency reuse factor. 虽然最为理想的频率复用系数为1,但若固定使用频率复用系数1,则不可避免地在相邻小区之间引入较大的干扰,而干扰必然限制了小区的吞吐量和用户性能的提升。 While the ideal frequency reuse factor of 1, but if the fixed frequency reuse factor 1, will inevitably introduce large interference between adjacent cells, interference necessarily limits the throughput of the cell performance and user upgrade. 为此,本发明提供了一种资源管理方法。 To this end, the present invention provides a resource management method. 请参阅图4,其为本发明演进移动通信系统的资源管理方法的流程图。 Please refer to FIG. 4, a flowchart of enhanced resource management method in a mobile communication system in which the present disclosure. 它包括: it includes:

[0057] SllO =E-NodeB为本小区中靠近E-NodeB的用户配置无线资源,并实时向CPS上报E-NodeB无线资源的配置结果。 [0057] SllO = Configuration E-NodeB cells present near the user's E-NodeB configuring the wireless resources, time reporting of E-NodeB and the radio resources to the CPS.

[0058] S120:CPS依据预先保存的各小区之间的邻接关系、各小区资源制约关系及E-NodeB上报的无线资源配置结果为下辖的各个小区中靠近小区边缘用户配置无线资源。 [0058] S120: CPS based on adjacency relationships among pre-stored cells, each cell in each cell a radio resource configuration and resource constraint relationships reported for the E-NodeB administered near the cell edge users in a radio resource configuration.

[0059] 本发明充分考虑基于OFDM蜂窝小区的干扰特征,为小区中靠近E-NodeB的用户在全频/时域空间(频率复用系数1)中分配无线资源,而靠近小区边缘的用户使用频率动态复用技术基于相邻边缘用户的无线资源之间正交的原则分配无线资源。 [0059] The present invention fully contemplates based on the interference characteristics OFDM cell, the user of the cell near the E-NodeB allocation of radio resources in the whole frequency / time domain space (frequency reuse factor 1), the user near the cell edge usage dynamic multiplexing frequency radio resources are allocated based on the principle of orthogonal between adjacent edges of the user's wireless resources.

[0060] 首先,E-NodeB设定小区的边缘区域,位于小区边缘区域的用户即为步骤S120中靠近小区边缘的用户。 [0060] First, E-NodeB in cell edge area is set, the user in step S120 is the user located near the cell edge of the cell-edge area. E-NodeB可以设定边缘区域阈值,用户对应的值与边缘区域阈值进行比较,从而确定用户位于小区的边缘区域还是位于靠近E-NodeB区域。 E-NodeB edge area threshold may be set, a value corresponding to the user edge area threshold value, to thereby determine the user located in the cell edge region or area is located near the E-NodeB. 比如,E-NodeB可以基于信号导频强度来设定边缘区域导频阈值,从用户上报的测量报告获得用户的信号导频强度,当用户的信号导频强度大于预设的边缘区域导频阈值,则用户位于靠近E-NodeB区域,否则用户位于小区的边缘区域; For example, E-NodeB may be set in the edge region of the pilot threshold pilot signal strength obtained based on the signal conductors user pilot strength measurement report reported by the user, when the signal conductors user pilot strength greater than a preset region of the guide edge pilot threshold the user is located close to area E-NodeB, or user located at the edge area of ​​the cell;

[0061] 然后,当用户发起接入请求时,E-NodeB判断用户处于小区的位置,当处于靠近E-NodeB区域,则由E-NodeB分配无线资源,并向CPS实时上报E-NodeB无线资源的配置结果。 [0061] Then, when the user initiates an access request, E-NodeB determines the position of the user in the cell, E-NodeB when the radio resources in the region close to the E-NodeB, by the E-NodeB allocate radio resources, and time reporting of CPS the configuration. 当处于小区的边缘区域,则由CPS配置无线资源。 When in the edge region of the cell, radio resource configuration by the CPS.

[0062] 当用户处于通话过程中,E-NodeB实时检测用户所处的位置,若用户进入小区的边缘区域,则由CPS动态为该用户分配无线资源。 [0062] When the user is in a call, E-NodeB in which the position of the user detected in real time, if the user enters an edge area of ​​a cell, CPS by dynamically allocating radio resources for the user.

[0063] CPS配置无线资源具体为:CPS确定需要配置无线资源的用户的源小区;02) CPS根据源小区的邻接关系找到所述用户靠近的邻小区信息;03)CPS基于相邻小区边缘用户的无线资源之间正交的原则,给所述用户分配无线资源。 [0063] CPS radio resource configuration specifically: CPS determines that a radio resource configuration of the user's source cell; 02) CPS found close to the neighbor cell information of the user according to the source cell adjacency; 03) CPS based on the neighbor cell edge user principles of radio resources are orthogonal, radio resources are allocated to the user.

[0064] 也就是说,位于小区边缘区域的用户的无线资源分配是需要考虑相邻小区已配置资源的影响和制约——故其频谱的分配是条件受限的。 [0064] That is, a user located in a cell edge area of ​​the radio resource allocation is configured to consider the influence neighboring cell and resource constraints - so its spectrum allocation is limited conditions. 即,频率复用系数大于1,而且是随相邻小区已用资源动态变化的。 I.e., frequency reuse factor greater than 1, but with the cell change has Dynamic resource adjacent.

[0065] 请参阅图5,其为UE(用户)无线资源复用场景的一实施示意图。 [0065] Please refer to FIG. 5, a schematic embodiment of a radio resource scene UE (user) multiplexing. 参照图5,具体说明资源配置。 Referring to FIG. 5, described in detail the allocation of resources.

[0066] 处于小区1中的三个UE(在图中分别以圆点、正方形和三角形来标识,并依次命名为限、呢和冊。)由于所处的干扰环境不同,应当采用不同的动态复用参数: [0066] UE in three cells 1 (respectively circles, squares and triangles in the figures are identified, and named sequentially limited, and it copies.) Due to the different environments in which the interference should be different dynamic multiplexing parameters:

[0067] ①对于UEa,由于其处于小区1内较为靠近E-NodeB的区域,故其受到的邻小区干扰较弱,不会影响业务的正常运作,可以在全频/时域空间中为其分配无线资源; [0067] ① For UEa, since it is in a cell area relatively close to the E-NodeB 1, it is received by its neighbor cell interference is weak, will not affect the normal operation of the service, it may be at its full frequency / time domain space allocation of radio resources;

[0068] ②对于给UEb,其处于小区1和小区3的交接处——即处于小区1的边缘,此时分配无线资源时,不但要遵循小区1内的配置准则同时应当兼顾小区3施加干扰的可能性,必须在给UEb配置无线资源时规避小区3中已配置的资源; [0068] ② For a UEb, which junction in the cell 1 and cell 3, - i.e., at the edge of the cell 1, when assigning radio resources at this time, not only to follow the guidelines contained in the cell configuration 1 3 It should also be taking into account the interfering cell possibility, cells must evade 3 resources configured at a radio resource configuration UEb;

[0069] ③对于UE。 [0069] ③ for the UE. ,由于其所处的位置更为特殊,配置无线资源时,既要遵循小区1内的配置准则又要规避小区3和小区2中已配置的资源。 , Due to its location which is more special, when you configure the wireless resources, it is necessary to follow the configuration guidelines in the cell 1 and also to avoid the resource has been configured cell 2 and cell 3.

[0070] 请参照图6,其为小区边缘区域定义的实例图。 [0070] Referring to FIG 6, which is defined for the example of FIG cell edge area. 假定某个小区中可用的带宽为Ω, 将其分割为两部分带宽资源:带宽资源A和带宽资源B。 Suppose a cell available bandwidth Ω, which is divided into two bandwidth: bandwidth resources and bandwidth resource B. A 小区中落入边缘区域的用户使用带宽资源B,而位于本小区内且位于边缘区域外的用户使用带宽资源A。 Users in the cell edge area falls bandwidth resources B, located within the cell and present use of bandwidth resources in a user area of ​​the outer edge A. 其中,使用带宽资源A的用户,基于OFDM技术的特点可设置其带宽资源复用系数为1,在资源配置过程中可由E-Node B直接配置,不必考虑邻小区的干扰,上述带宽资源复用可称之为静态复用机制。 Wherein the user bandwidth resource A, based on the characteristics of OFDM techniques may set its bandwidth resource reuse factor of 1, by the E-Node B directly arranged in the resource allocation process, regardless of the interference of neighboring cells, the above-described bandwidth resource reuse It can be called a static multiplexing mechanism. 而使用带宽资源B的用户,由于处于边缘区域内,必须考虑邻小区的干扰问题,用户资源配置过程中基于CPS所掌握的小区资源信息由E-Node B和CPS协作实施动态配置,上述带宽 Bandwidth resources because the user B, since in the edge region, adjacent cell interference problem must be considered, CPS disposal cell resource information from the E-Node B dynamically configured and implemented in collaboration CPS users based on the resource allocation process, the bandwidth of the above

9资源复用可称之为动态复用机制。 9 may be called dynamic resource multiplexing multiplexing mechanism. 总体而言,本发明的资源配置过程有机结合了资源的动态和静态复用机制。 In general, the resource allocation process according to the present invention, organic combination of static and dynamic resource reuse mechanism.

[0071] 在具体的应用中可以依据UE上报的测量结果来确定具体的判定门限。 [0071] In a particular application may be determined based on a particular decision threshold measurement result reported by the UE. 小区中边缘区域应为近似的环行区域。 In the cell edge area should approximate circular area. 当UE落入边缘区域时设置其状态标记EDGERING为1 ;而UE 未落入边缘区域时设置其状态标记EDGERING为0。 EDGERING set its status flag when the UE falls within the edge region is 1; provided that the state flag is 0 EDGERING UE does not fall within the edge region. CPS和E-NodeB根据状态标记EDGERING 来获得UE所处小区的位置,以便完成后续UE的资源配置。 CPS and E-NodeB according to the state flag obtained EDGERING location of the UE located in the cell, the allocation of resources in order to complete the follow-up of the UE.

[0072] S130:当用户发生切换时,目标E-NodeB根据步骤S120配置的无线资源完成所述切换用户的资源配置。 [0072] S130: When a user switching occurs, the target E-NodeB S120 step according to a radio resource configuration of the handover complete user resource configuration.

[0073] 通过上述的资源配置过程,得到了相邻小区边缘各个用户的无线资源之间正交这一技术结果。 [0073] By the above-described resource allocation process, this technique results obtained between the orthogonal radio resources to each user in neighboring cell edge. 当用户发生切换时,目标E-NodeB可以直接采用源E-NodeB分配至该用户的资源作为目标小区给该用户的资源配置,这种用户自带资源进行切换的过程,可以在小区无线配置时省略为切换用户预留切换资源,提高了整个小区无线资源的使用效率。 When the user switch occurs, the target E-NodeB can be directly used source E-NodeB resources assigned to the user as a target cell resource allocation to the user, such user's own resource switching process, may be arranged in the radio cell reserve resources for handover omitting switch user, improves the efficiency of the entire cell radio resources.

[0074] 上述步骤S130在目标小区为切换用户配置资源时,目标E-NodeB可以直接采用用户的自带资源,也可以优先参考该用户的自带资源,比如当用户自带资源在目标小区的通信质量好时,直接采用用户的自带资源作为本目标小区为该用户配置的资源,若用户自带资源在目标小区的通信质量不佳时,可以采用其它方式配置用户资源,比如根据UE的QoS 计算并配置用户资源。 [0074] In the above-described step S130 to the target cell when the handover users resource configuration, target E-NodeB can be directly used users own resources, priority may refer to the user's own resources, such as when the user's own resources in a target cell when the communication quality is good, the direct use of the user's own resources as a resource configuration of the present target cell for the user, if the user carrying the communication quality is poor resources of the target cell may be employed otherwise configured user resource, such as a UE in accordance with QoS and configure user computing resources. 其具体实现过程如下: The specific process is as follows:

[0075] (31)目标小区为预接入用户配置资源时,若步骤S120配置给用户的源配置资源在目标小区的通信质量落在预设的阈值范围内,则采用源配置资源; When [0075] (31) a target cell pre-allocation of resources to the user access, step S120 if the user's source configured to allocate resources within the communication quality of the target cell is within a preset threshold range, the use of source allocation of resources;

[0076] (32)若用户源配置资源在目标小区的通信质量落在预设阈值范围之外,则依据所述用户的服务质量QoS计算并重新配置切换用户资源。 [0076] (32) If the user of the source resource allocation falls within a preset threshold range communication quality than the target cell is calculated according to the QoS of the user and the user switches to reconfigure resources.

[0077] 并且,切换过程完毕后,将切换用户的源配置资源融合到目标小区资源池中,以便进行资源的共享统一调度。 [0077] Then, when the handover process is completed, the user switches the source to the target cell fusion allocation of resources in a resource pool, for the unified shared resource.

[0078] 通过上述的配置过程,UE自带资源切换与原有的资源预备过程相结合,可以有效防止目标资源异常的特殊场景,提升切换的成功率;同时也降低了在切换过程中引入抢占机制的可能性。 [0078] Through the above configuration, the UE comes handover resource preparation process of the original resource combination can effectively prevent abnormal target scene specific resources, improve the success rate of handover; also reduces preemption introduced during handover the possibility of mechanisms.

[0079] 基于资源的动态和静态复用机制,本发明在此基础上提供了一种演进无线通信系统的切换方法。 [0079] Based on static and dynamic resource reuse mechanism, the present invention provides a handover method in a wireless communication system is an evolved on this basis. 请参阅图7,其为该切换方法的流程图。 Please refer to FIG. 7, a flowchart for the switching process. 它包括以下步骤: Comprising the steps of:

[0080] S210 =CPS根据源E-NodeB提供的用户的测量报告,选择目标小区及伴随的目标E-NodeB。 [0080] S210 = CPS source user according to the measurement reports provided by the E-NodeB, the target cell selection and the associated target E-NodeB.

[0081] 在步骤S210之前,整个无线通信系统需要预先进行用户的资源分配:用户发起接入请求或用户通话过程,若检测到用户处于小区的边缘区域,CPS基于相邻小区边缘用户的无线资源之间正交的原则依据预先保存的各小区之间的邻接关系、各小区资源制约关系及E-NodeB上报的无线资源处理结果为所述用户动态配置无线资源。 [0081] Before step S210, the entire wireless communication system resource allocation need to pre-user: a user or a user initiates a call access request, if the user is detected at the edge area of ​​the cell, the neighboring cell edge user based on the CPS radio resources adjacency relationship between the cells based on the principle of quadrature between the pre-stored radio resource processing result of each cell and resource constraints E-NodeB relationship reported by the user to dynamically configure the radio resources. 用户处于小区的边缘区域是通过以下步骤检测获得:从用户上报的测量报告中获得用户导频信息,当用户导频强度小于边缘区域门限值时,所述用户处于小区的边缘区域。 Users at the cell edge detection region is obtained by the steps of: obtaining user information from the pilot measurement report reported by the user, when the user is less than the edge region of the pilot strength threshold, the user is in the edge region of the cell.

[0082] UE向源E-NodeB发送测量报告,所述测量报告至少包括候选小区导频质量信息; 源E-NodeB将收到的测量报告通过其与CPS之间的接口上报给CPS ;CPS根据源E-NodeB提供的UE的测量报告及其记录各个小区的无线资源可用状态及处理负荷量选择目标小区及伴随的目标E-NodeB。 [0082] UE to the source E-NodeB sending the measurement report, the measurement report including at least quality information of a pilot candidate cells; source E-NodeB will receive a measurement report reported by the interface between it and the CPS CPS; CPS according UE measurement reports provided by the source E-NodeB each cell and a recording state of available radio resources and the processing load of the target cell selection and the associated target E-NodeB.

[0083] S220 =CPS/源E-NodeB向目标E-NodeB发送切换预备请求消息,所述切换预备请求消息至少携带用户源配置无线资源信息。 [0083] S220 = CPS / source E-NodeB sends a handover preparation request message to the target E-NodeB, the handover preparation request message carries at least a source user to configure the wireless resource information.

[0084] 切换的实现过程包括CPS主控的切换过程及E-NodeB主控/CPS协控的切换过程两种实现方式,后续会具体介绍这两种实现方式。 Implementation [0084] handover procedure including CPS switching master and the master switching process E-NodeB / CPS co-controlled two implementations, the subsequent detailed description of these will be implemented in two ways. 这两种切换实施过程在切换决策实施、资源预备请求及数据链路的转接请求等消息的发起节点会有不同——CPS或相关的E-NodeB0 Both originating switching node messages in the handover decision implementation embodiment, the resource preparation request and the transfer request data link or the like have different --CPS associated E-NodeB0

[0085] CPS/源E-NodeB向目标E-NodeB发送切换预备请求消息,要求目标E-NodeB进行切换资源的准备。 [0085] CPS / source E-NodeB sends a handover preparation request message, requires that the target E-NodeB handover resource preparation in the target E-NodeB. 在切换预备请求消息中需要携带用户源配置无线资源信息及UE相关的QoS0 In the handover preparation request message carries the user needs to configure the radio resource information source and related UE QoS0

[0086] S230:目标E-NodeB接收到切换预备请求消息后,依据用户源配置无线资源信息配置切换资源,并向CPS/源E-NodeB返回切换预备确认。 [0086] S230: the target E-NodeB, after receiving the handover preparation request message, a radio resource configuration based on the configuration information of the source user to switch resources, and CPS / source E-NodeB handover preparation acknowledgment returned.

[0087] 目标E-NodeB可以直接采用用户源配置无线资源信息作为目标小区对用户进行的资源配置。 [0087] E-NodeB target user can be directly used as the source configuration resource allocation radio resource information for the target cell of the user. 目标E-NodeB也可以采用以下配置方式配置切换用户的资源:目标E-NodeB 为预接入用户配置资源时,若用户源配置资源在目标小区的通信质量落在预设的阈值范围内,则采用用户源配置无线资源;若用户自带资源在目标小区的通信质量落在预设阈值范围之外,则依据所述用户的服务质量QoS计算并配置用户资源。 Target E-NodeB may be configured in the following configuration switch user resources: the target E-NodeB user access to pre-allocation of resources, the user of the source if the communication quality of the allocation of resources in the target cell is within a preset threshold range, then source configuration using a radio resource user; if the user carrying the communication resources in the target cell quality falls outside a predetermined threshold range, and is calculated according to the user configure user resource quality of service QoS.

[0088] 当资源配置后,目标E-NodeB向CPS/源E-NodeB返回切换预备确认消息,所述消息除了携带切换时间外,还可以根据需要确定是否携带为切换用户配置的资源。 [0088] After the resource allocation, the target returns to the E-NodeB CPS / source E-NodeB handover preparation acknowledgment message, except the message carries the switching time, but also can determine whether it carries resource allocation to switch user as required. 比如,当目标E-NodeB直接采用用户源配置无线资源信息作为目标小区对用户进行的资源配置时,目标E-NodeB在切换预备确认消息可以携带配置的资源(用户源配置无线资源),也可以采用缺省的方法,即不携带配置的资源或采用某种方法予以指示;当目标E-NodeB不采用用户源配置无线资源信息作为目标小区对用户进行的资源配置,而是依据所述用户的服务质量QoS计算并配置用户资源时,目标E-NodeB在切换预备确认消息中应携带为切换用户重新配置的资源信息。 For example, when the target E-NodeB directly used when the user of the source configuring the wireless resource information as the resources of the target cell of the user, the target E-NodeB (Configuration of radio resources for the source) in the resource handover preparation acknowledgment message may carry the configuration may be use the default method, i.e., does not carry the resource allocation or a method is used to be indicated; E-NodeB when the target user is not using the radio resource information source configured as a resource for the target cell on the user's configuration, but according to the user when the quality of service QoS configuration and user computing resources in the target E-NodeB handover preparation acknowledgment message carries resource information should be reconfigured to switch user.

[0089] S240 =CPS/源E-NodeB向Evolved CN请求数据链路的转接,并向用户指示切换过程的发起,所述指示消息中携带切换资源信息。 [0089] S240 = CPS / source E-NodeB to Evolved CN transfer request data link, indicating to the user initiates a handover procedure, the handover indication message carries resource information. 所述切换资源信息包括为所述切换用户配置资源及切换时间。 The handover to the handover resource information includes resource allocation and user switching time.

[0090] Evolved CN用户面对UE进行数据链路转换完成后,Evolved CN用户面下发的数据由目标E-Node B进行缓存。 [0090] Evolved CN facing UE user data link after the conversion is complete, issued by Evolved CN user plane data cached by the target E-Node B.

[0091] S250 :用户依据指示的切换资源信息向目标E-NodeB发起同步。 [0091] S250: switch resources based on user information indicated initiate synchronization to the target E-NodeB.

[0092] S260 :同步完成后,用户从目标E-NodeB接收数据,并释放源E-NodeB的无线资源。 [0092] S260: After the synchronization is completed, the user receives the data from the target E-NodeB, and releases the radio resources in the source of the E-NodeB.
