本发明涉及无线通信技术，具体的讲是一种无线接入网络的重组方法、系统及重组控制器。The invention relates to wireless communication technology, in particular to a wireless access network reorganization method, system and recombination controller.
背景技术Background technique
第二代移动通信系统(例如GSM和IS95)与第三代移动通信系统(例如3GPP WCDMA R99和3GPP2CDMA20001x)的无线接入网络的架构均为树状层次结构。基站是处于最底层的叶子节点，处于基站之上的是基站控制器。基站主要负责空中接口的物理层，例如中频信号和基带信号处理，射频信号发送/接收。基站控制器主要负责空中接口的二三层处理。The architecture of the wireless access network of the second generation mobile communication system (such as GSM and IS95) and the third generation mobile communication system (such as 3GPP WCDMA R99 and 3GPP2CDMA20001x) is a tree-like hierarchical structure. The base station is the leaf node at the bottom layer, and the base station controller is above the base station. The base station is mainly responsible for the physical layer of the air interface, such as intermediate frequency signal and baseband signal processing, and radio frequency signal transmission/reception. The base station controller is mainly responsible for the second and third layer processing of the air interface.
一个基站控制器管理一个或者多个基站，而一个基站能且只能被一个基站控制器管理。基站控制器与它所控制的基站构成一个无线网络子系统。无线网络子系统作为一个独立单元提供无线接入承载，将覆盖区域内的终端接入到核心网设备上开展电路或者数据业务。One base station controller manages one or more base stations, and one base station can and can only be managed by one base station controller. The base station controller and the base stations it controls form a wireless network subsystem. As an independent unit, the wireless network subsystem provides wireless access bearer, and connects the terminals in the coverage area to the core network equipment to carry out circuit or data services.
如图1所示为典型的移动通信系统接入网的树状层次结构，基站控制器与基站之间的归属关系是预先确定的。在设备运行期间，基站控制器与基站的归属关系不能随意变化。当基站的归属关系需要从某个基站控制器划到另外某个基站控制器时，必须先中断基站的运行，然后在修改基站和相关基站控制器的配置信息，最后才能使基站在新基站控制器下启动并提供正常的业务。As shown in Fig. 1, it is a tree-like hierarchical structure of a typical mobile communication system access network, and the ownership relationship between the base station controller and the base station is predetermined. During the operation of the equipment, the ownership relationship between the base station controller and the base station cannot be changed arbitrarily. When the ownership relationship of a base station needs to be transferred from one base station controller to another, the operation of the base station must be interrupted first, and then the configuration information of the base station and related base station controllers must be modified before the base station can be controlled by the new base station. server and provide normal services.
第二代移动通信系统和早期的第三代移动通信系统(例如3GPP WCDMAR99)的无线接入网络都是直接使用第二层(链路层)技术完成传输信令和数据的功能，例如：时分多路复用(TDM：Time Division Multiplex)传输技术，如E1/T1；或者ATM的PVC(永久虚电路)。但这些技术都不具备第三层(网络层)技术的路由能力。换言之，基站只和建立二层链路的基站控制器“连通”，与其它基站控制器是“不连通”的。The wireless access network of the second-generation mobile communication system and the early third-generation mobile communication system (such as 3GPP WCDMA R99) directly uses the second layer (link layer) technology to complete the function of transmitting signaling and data, such as: time division Multiplexing (TDM: Time Division Multiplex) transmission technology, such as E1/T1; or PVC (Permanent Virtual Circuit) of ATM. But none of these technologies has the routing capability of the third layer (network layer) technology. In other words, the base station is only "communicated" with the base station controller that establishes the layer-2 link, and is "disconnected" with other base station controllers.
第三代移动通信的后期版本(例如3GPP WCDMA R4/R5/R6)开始在无线接入网络接纳IP技术作为传输技术。这些版本既允许使用原有的二层技术构筑传输网，也允许使用IP技术构筑传输网。采用IP技术构筑无线接入网络的传输网，无论链路层使用何种技术(例如E1或者ATM的永久虚电路)，基站与所有的基站控制器都是“连通”的。因为基站发出的数据包通过链路层技术传送到具有路由功能的节点，这些节点可以将数据转发到目的节点去。Later versions of the third-generation mobile communication (such as 3GPP WCDMA R4/R5/R6) began to adopt IP technology as the transmission technology in the wireless access network. These versions not only allow the use of the original two-layer technology to build the transmission network, but also allow the use of IP technology to build the transmission network. The transmission network of the wireless access network is built using IP technology. No matter what technology is used in the link layer (such as E1 or ATM permanent virtual circuit), the base station and all base station controllers are "connected". Because the data packet sent by the base station is transmitted to the node with routing function through the link layer technology, these nodes can forward the data to the destination node.
3GPP2制定的3G标准也有同样的趋势，使用IP技术作为无线接入网络的传输技术。如图2所示为3GPP WCDMA R99的无线接入网络的架构。The 3G standard formulated by 3GPP2 also has the same trend, using IP technology as the transmission technology of the wireless access network. Figure 2 shows the architecture of the wireless access network of 3GPP WCDMA R99.
图2中，无线网络控制器(RNC：Radio Network Controller)即为基站控制器在3GPP WCDMA系统中的称呼，节点B(Node B)即为基站在3GPP WCDMA系统中的称呼。为了保持一致便于理解，后面我们仍然使用基站控制器和基站的名称。图中OMC-R(Operation and Maintenance Center-Radio Part)是操作维护中心-无线部分。OMC-R是网管人员操作控制无线网络子系统设备的平台，其包括：配置管理、故障管理、性能管理、计费管理和安全管理等功能。OMC-R与基站控制器和基站之间的接口是基于简单网络管理协议(SNMP：SimpleNetwork Management Protocol)的接口。In Figure 2, the radio network controller (RNC: Radio Network Controller) is the name of the base station controller in the 3GPP WCDMA system, and the node B (Node B) is the name of the base station in the 3GPP WCDMA system. For consistency and easy understanding, we still use the names of base station controller and base station later. In the figure, OMC-R (Operation and Maintenance Center-Radio Part) is the operation and maintenance center-radio part. OMC-R is a platform for network administrators to operate and control wireless network subsystem equipment, including functions such as configuration management, fault management, performance management, billing management, and security management. The interface between OMC-R, base station controller and base station is based on Simple Network Management Protocol (SNMP: SimpleNetwork Management Protocol).
基站控制器与基站之间是一对多的关系。一个基站控制器控制一个或者多个基站，一个基站只能被一个基站控制器所控制。当基站控制器失效时，即使无线网络子系统的基站都可以正常工作，但基站控制器所在无线网络子系统全部失效。因为基站只能处理空中接口物理层的功能，基站控制器完成空中接口二三层功能。没有基站控制器的配合，基站无法提供空中链路的承载服务。There is a one-to-many relationship between the base station controller and the base stations. One base station controller controls one or more base stations, and one base station can only be controlled by one base station controller. When the base station controller fails, even if the base stations of the wireless network subsystem can work normally, all the wireless network subsystems where the base station controller is located fail. Because the base station can only handle the functions of the physical layer of the air interface, the base station controller completes the functions of the second and third layers of the air interface. Without the cooperation of the base station controller, the base station cannot provide the bearer service of the air link.
在设备运行期间，这种归属关系不能随意变化。如果将原来属于基站控制器A的基站划到基站控制器B的管辖范围下，必须中断基站的运行，修改基站和相关基站控制器的配置信息，然后才能使基站在新的基站控制器下启动和提供正常的业务。而上述的整个过程需要人工干预才能够完成。During the operation of the equipment, this ownership relationship cannot be changed arbitrarily. If the base station originally belonging to base station controller A is assigned to the jurisdiction of base station controller B, the operation of the base station must be interrupted, and the configuration information of the base station and related base station controllers must be modified before the base station can be started under the new base station controller and provide normal business. The above-mentioned whole process needs manual intervention to be able to complete.
3GPP WCDMA R99使用点对点的永久虚电路(PVC)作为无线接入网络的基本的传输技术手段，所有的信令(包括无线网络层的信令与传输网络层的信令)和用户数据都使用永久虚电路(PVC)传输。3GPP WCDMA R99 uses a point-to-point permanent virtual circuit (PVC) as the basic transmission technology of the wireless access network. All signaling (including signaling at the wireless network layer and signaling at the transport network layer) and user data use permanent Virtual Circuit (PVC) transport.
3GPP WCDMA R99无线接入网络在操作中存在以下的主要缺点：3GPP WCDMA R99 wireless access network has the following main shortcomings in operation:
1.单点故障。基站控制器成为无线网络子系统的故障单点。一旦基站控制器失效，整个无线网络子系统将失效。即使此无线网络子系统的基站都能够正常工作也不能为用户提供服务。随着无线网络子系统规模的增大，基站控制器失效的严重性也日益增大。因为基站控制器失效将使几十乃至数百的基站不能工作，影响的用户数目成千上万。1. Single point of failure. The base station controller becomes a single point of failure for the wireless network subsystem. Once the base station controller fails, the entire wireless network subsystem will fail. Even if the base stations of the wireless network subsystem can work normally, they cannot provide services for users. As the scale of wireless network subsystems increases, the severity of base station controller failures also increases. Because the failure of the base station controller will make dozens or even hundreds of base stations unable to work, affecting thousands of users.
2.基站控制器升级时整个无线网络子系统将失效。2. The entire wireless network subsystem will fail when the base station controller is upgraded.
3.网络扩容时需要将一部分基站从原来的归属基站控制器割接到新的归属基站控制器，必须通过人工修改复杂的配置信息修改，以改变基站和基站控制器的归属关系。而且，人工操作过程复杂，耗时长且容易出错而，容易对网络的正常运行造成不良影响。3. During network expansion, it is necessary to cut over some base stations from the original home base station controller to the new home base station controller. It is necessary to manually modify complex configuration information to change the ownership relationship between the base station and the base station controller. Moreover, the manual operation process is complex, time-consuming and error-prone, which can easily cause adverse effects on the normal operation of the network.

具体实施方式Detailed ways
图3所示为本发明支持自动重组功能的无线接入网络的一实施例的架构图。FIG. 3 is a structural diagram of an embodiment of a radio access network supporting an automatic reassembly function according to the present invention.
图3中，无线接入网络架构包括：操作维护中心(OMC)、基站控制器，基站、重组控制器及配置数据库。OMC与基站控制器的接口为X1A，OMC与基站的接口为X1B，重组控制器与基站控制器的接口为X2A，重组控制器与基站的接口为X2B，重组控制器与OMC的接口为X3。In Fig. 3, the wireless access network architecture includes: an operation and maintenance center (OMC), a base station controller, a base station, a reorganization controller, and a configuration database. The interface between OMC and base station controller is X1A, the interface between OMC and base station is X1B, the interface between reorganization controller and base station controller is X2A, the interface between reorganization controller and base station is X2B, and the interface between reorganization controller and OMC is X3.
重组控制器用于控制自动重组无线接入网络的过程。重组控制器与配置数据库相连，在无线接入网络的重组过程中，重组控制器用于查询配置数据库存储的信息为基站选择合适的新的基站控制器，并修改OMC后台数据库中存储的基站控制器配置信息及基站配置信息，此外重组控制器还可用于直接修改基站控制器的配置信息。图3中的重组控制器是独立设置的功能实体，如一独立服务器。无线接入网络中可以设置一个或者多个重组控制器。当无线接入网络架构中设置多个重组控制器时，各重组控制器相互之间独立工作，但各重组控制器均连接至同一配置数据库。因为逻辑上系统中只能设置一个配置数据库。The reorganization controller is used to control the process of automatic reorganization of the radio access network. The reorganization controller is connected to the configuration database. During the reorganization process of the wireless access network, the reorganization controller is used to query the information stored in the configuration database to select a suitable new base station controller for the base station, and to modify the base station controller stored in the OMC background database. Configuration information and base station configuration information, in addition, the reorganization controller can also be used to directly modify the configuration information of the base station controller. The reorganization controller in FIG. 3 is an independently set functional entity, such as an independent server. One or more reassembly controllers may be set in the radio access network. When multiple reconfiguration controllers are set in the radio access network architecture, each reconfiguration controller works independently of each other, but each reconfiguration controller is connected to the same configuration database. Because logically only one configuration database can be set in the system.
图3中的配置数据库为一独立的数据库供重组控制器所用。配置数据库用于存储：无线接入网络架构中的全局信息和基站配置信息。全局信息包括：基站控制器与基站关系信息、备选基站控制器信息、基站控制器状态信息、相邻小区信息。基站配置信息则包括：基站公共信息、基站小区信息。The configuration database in Figure 3 is a separate database for use by the reconfiguration controller. The configuration database is used to store: global information in the wireless access network architecture and base station configuration information. The global information includes: base station controller and base station relationship information, candidate base station controller information, base station controller status information, and adjacent cell information. The base station configuration information includes: base station public information and base station cell information.
在无线接入网络中，还可将重组控制器或配置数据库合设在其它设备中，譬如：将重组控制器和配置数据库合设于OMC中，如图4所示的本发明支持自动重组功能的无线接入网络的另一实施例的架构图。In the wireless access network, the reorganization controller or the configuration database can also be combined in other devices, for example: the reorganization controller and the configuration database can be combined in the OMC, as shown in Figure 4, the present invention supports the automatic reorganization function An architecture diagram of another embodiment of a wireless access network.
图4中，重组控制器与配置数据库合设于OMC，重组控制器为OMC的一部分子功能，配置数据库为重组控制器与OMC合用的数据库。OMC与重组控制器间的接口X3为内部接口，重组控制器与基站控制器间通过OMC与基站控制器间的接口X1A通信，重组控制器与基站间通过OMC与基站间的接口X1B通信。In Fig. 4, the reorganization controller and the configuration database are co-located in the OMC, the reorganization controller is a sub-function of the OMC, and the configuration database is a database shared by the reorganization controller and the OMC. The interface X3 between the OMC and the recombination controller is an internal interface, the recombination controller and the base station controller communicate through the interface X1A between the OMC and the base station controller, and the recombination controller and the base station communicate through the interface X1B between the OMC and the base station.
图3、图4中，每个基站控制器的本地数据库中存储有其自身的物理设备配置信息、通信配置信息、管辖的基站配置信息及小区等配置信息；每个基站本地数据库中存储有其自身的物理设备配置信息、通信配置信息、覆盖的小区等配置信息。对于本领域技术人员来说，基站控制器(基站)本地数据库中存储的配置信息，以及配置信息的配置方式都是公知技术，譬如，采用相互关联的表结构存储基站控制器(基站)的配置信息，或将基站控制器(基站)的配置信息集中存储等等方法，与本发明的发明点无关，因而不再详细介绍。在此需要说明的是，虽然图3与图4的无线接入网络架构中只给出了一OMC，但是在实际组网中，各无线接入网络架构中可设置多个OMC，各OMC的后台数据库中存储有其管理的基站控制器和基站的配置信息。In Fig. 3 and Fig. 4, the local database of each base station controller stores its own physical equipment configuration information, communication configuration information, base station configuration information under its jurisdiction, and configuration information such as cells; each base station local database stores its own Configuration information such as its own physical equipment configuration information, communication configuration information, and covered cells. For those skilled in the art, the configuration information stored in the local database of the base station controller (base station) and the configuration method of the configuration information are all known technologies, for example, the configuration of the base station controller (base station) is stored in an interrelated table structure Information, or the method of centrally storing the configuration information of the base station controller (base station), etc., has nothing to do with the invention point of the present invention, so it will not be described in detail. It should be noted here that, although only one OMC is shown in the wireless access network architectures of Figures 3 and 4, in actual networking, multiple OMCs can be set in each wireless access network architecture, and each OMC The background database stores configuration information of base station controllers and base stations managed by it.
OMC后台数据库存储的基站控制器配置信息和基站配置信息，与OMC所管理的基站控制器的和基站的配置信息是一一对应的，即映射关系，两份配置信息是完全相同。如图5所示，当修改OMC的后台数据库中存储的基站控制器和基站配置信息信息，OMC可通过X1A或X1B接口的网管操作使得其自身的后台数据库信息与基站控制器数据库信息或基站数据库信息同步，更新基站控制器和基站的配置信息。The base station controller configuration information and base station configuration information stored in the OMC background database are in one-to-one correspondence with the base station controller and base station configuration information managed by the OMC, that is, the mapping relationship, and the two configuration information are exactly the same. As shown in Figure 5, when modifying the base station controller and base station configuration information stored in the background database of OMC, OMC can make its own background database information and base station controller database information or base station database through the network management operation of X1A or X1B interface Information synchronization, updating the configuration information of the base station controller and base station.
以下结合表结构对配置数据库中存储信息进行说明：The following describes the information stored in the configuration database in conjunction with the table structure:
表1：基站控制器与基站关系信息Table 1: Information about the relationship between the base station controller and the base station
表2：备选基站控制器信息Table 2: Alternative base station controller information
表3：基站控制器状态信息Table 3: Base Station Controller Status Information
表4：相邻小区信息Table 4: Adjacent cell information
为详细说明表4中的相邻小区信息，请参照图6所示的基站小区位置示意图。图5中有1，2，3，4个基站，假设每个基站覆盖四个小区，四个基站的各个小区ID分别编号为1，2，3，4。表4中，各基站ID与各小区ID的组合代表一个小区，相邻小区基站ID和相邻小区ID的组合代表一个相邻小区。如图6所示，小区1-2，即被基站1覆盖的小区2，分别与1-1、1-4、2-1，三个小区相邻。而小区3-2则分别与1-4、3-1、3-4、4-1相邻。For details of the adjacent cell information in Table 4, please refer to the schematic diagram of the cell location of the base station shown in FIG. 6 . There are 1, 2, 3, and 4 base stations in FIG. 5 , assuming that each base station covers four cells, and the cell IDs of the four base stations are respectively numbered 1, 2, 3, and 4. In Table 4, the combination of each base station ID and each cell ID represents a cell, and the combination of a neighboring cell base station ID and a neighboring cell ID represents a neighboring cell. As shown in FIG. 6 , cell 1-2, that is,
表5：基站公共信息Table 5: Base station public information
表5中的基站的信令面通信地址与用户面通信地址是不同的地址，对于本领域技术人员来说，基站的信令面通信地址与用户面通信地址可以根据硬件进行不同设置，譬如，可将基站的信令面通信地址与用户面通信地址设为同一个地址，或者将基站的信令面通信地址与用户面通信地址设为不同的地址情况下，将基站的用户面通信地址设置为基站的每个小区一个用户面通信地址。The signaling plane communication address and user plane communication address of the base station in Table 5 are different addresses. For those skilled in the art, the signaling plane communication address and user plane communication address of the base station can be set differently according to the hardware. For example, The signaling plane communication address of the base station and the user plane communication address can be set to the same address, or if the signaling plane communication address of the base station and the user plane communication address are set to different addresses, the user plane communication address of the base station can be set to One user plane communication address for each cell of the base station.
表6：基站的小区信息：Table 6: Cell information of the base station:
表7：基站控制器配置信息Table 7: Base Station Controller Configuration Information
在此需要说明的是，设计配置数据库的表结构时，无须按照上述表格配置将全局信息及基站配置信息。但是，全局信息必须包括：基站控制器与基站关系信息、备选基站控制器信息、基站控制器状态信息以及相邻小区信息在内的四种信息。同时各基站配置信息和基站控制器信息并不仅限于上述内容。接入技术或硬件不同，基站和基站控制器的配置信息也会有不同，对于本领域技术人员来说，配置数据库中存储的基站和基站控制器的配置信息是公知技术，因此在本发明的实施例中，同样不再详细介绍配置数据库中的基站和基站控制器的配置信息，仅列举与本发明实施最为相关的信息。It should be noted here that when designing the table structure of the configuration database, it is not necessary to configure the global information and the base station configuration information according to the above table. However, the global information must include: information about the relationship between base station controllers and base stations, information about candidate base station controllers, status information about base station controllers, and information about neighboring cells. Meanwhile, the configuration information of each base station and the base station controller information are not limited to the above contents. The configuration information of base stations and base station controllers will also be different due to different access technologies or hardware. For those skilled in the art, the configuration information of base stations and base station controllers stored in the configuration database is a known technology, so in the present invention In the embodiment, the configuration information of the base station and the base station controller in the configuration database will not be described in detail, and only the information most relevant to the implementation of the present invention will be listed.
以下结合实施例，详细说明本发明的无线接入网络络重组方法实施例的执行过程：The implementation process of the embodiment of the wireless access network reorganization method of the present invention will be described in detail below in combination with the embodiments:
实施例一：Embodiment one:
请参照图3及表1-表6，当基站控制器发生故障失效时，为了将失效基站控制器控制的基站重新连接到其它正常工作的基站控制器下继续提供服务时，由重组控制器控制无线接入网络重组，其重组过程包括：Please refer to Figure 3 and Table 1-Table 6. When the base station controller fails, in order to reconnect the base station controlled by the failed base station controller to other normal working base station controllers to continue to provide services, it is controlled by the reorganization controller Wireless access network reorganization, the reorganization process includes:
由重组组控制器通过其与基站控制器1之间的心跳协议监视基站控制器1的运行状态。一旦重组控制器检测到基站控制器1失效，重组控制器在配置数据库中将基站控制器1的状态更新为不可用，以防止基站控制器1被重选为其它基站的归属基站控制器。The operating status of the
重组控制器根据失效的基站控制器1的ID，在配置数据库查询受到影响的基站ID。根据配置数据库中存储的基站控制器与基站关系信息，重组控制器查询到基站1、基站2、基站3归属于基站控制器1，则基站1、基站2、基站3为受到影响的基站。The reorganization controller queries the ID of the affected base station in the configuration database according to the ID of the failed
重组控制器根据基站1、基站2、基站3的ID，在配置数据库中的备选基站控制器信息中，选择第一备选的基站控制器3为基站1、基站2、基站3的新的归属基站控制器。According to the IDs of
由于各基站的备选基站控制器分为：第一备选基站控制器，第二备选基站控制器和第三备选基站控制器。重组控制器在选择备选基站控制器时，需要逐级查询配置数据库中存储的基站控制器信息，以确定备选基站控制器的状态是否可以被选为新的归属基站控制器。The candidate base station controllers of each base station are divided into: a first candidate base station controller, a second candidate base station controller, and a third candidate base station controller. When the recombination controller selects a candidate base station controller, it needs to query the base station controller information stored in the configuration database step by step to determine whether the state of the candidate base station controller can be selected as the new home base station controller.
譬如：重组控制器根据基站控制器状态信息查询第一备选的基站控制器3的状态，若基站控制器3的状态不可用，则重组控制器查询基站1的第二备选基站控制器ID，结果为2，则重组控制器检查基站控制器2的状态是否可用。如果基站控制器的状态为可用，则选择基站控制器2为基站1的新的归属基站控制器。以此类推，选择新的归属基站控制器。若重组控制器查询的结果为基站1的所有备选基站控制器的状态均为不可用，则重组控制器停止将基站1接入无线接入网络的其它基站控制器。For example: the reorganization controller queries the status of the first candidate
在本实施例中，基站控制器3的状态为可用，重组控制器选择基站控制器3为基站1、基站2、基站3为的新的归属基站控制器，为使基站1、基站2、基站3接入基站控制器3，重组控制器必须将基站1、基站2、基站3本地数据库中存储的归属基站控制器通信地址(用户面通信地址和信令面通信地址)更新为基站控制器3的通信地址(用户面通信地址和信令面通信地址)，并在基站控制器3的配置信息中增加基站1、基站2、基站3的配置信息。In this embodiment, the state of the
重组控制器可根据基站控制器3的ID和基站1、基站2、基站3的ID，在配置数据库中分别查找基站控制器3的通信地址，以及基站1、基站2、基站3的公共信息和小区信息。由重组控制器通过接口X3修改OMC后台数据库中存储的基站控制器3和基站1、基站2、基站3的配置信息，即，重组控制器将OMC后台数据库中基站1、基站2、基站3的归属基站控制器通信地址修改为基站控制器3的通信地址，并将基站1、基站2、基站3的ID、公共信息、小区信息、及基站1、基站2、基站3的相邻小区信息增加在OMC后台数据库存储的基站控制器3的配置信息中。According to the ID of
然后，再由OMC通过X1A接口的网管操作更新基站控制器3的本地数据库中的配置信息，以及OMC通过X1B接口的网管操作将基站1、基站2、基站3中的归属基站控制器的通信地址(基站控制器的信令面地址、基站控制器的用户面地址)更新为基站控制器3的通信地址。基站1、基站2、基站3根据本地数据库中的基站控制器3的通信地址，接入基站控制器3，继续提供服务。Then, the configuration information in the local database of
由于基站控制器3新增的基站1、基站2、基站3扩大了基站控制器3的地理覆盖范围，因此需要在基站控制器3的配置信息中增加相邻小区信息。Since the
本实施例中，基站控制器3的配置信息中增加的相邻小区信息包括4-1，4-2，4-3。这是因为，基站1、基站2和基站3的部分相邻小区属于其它基站覆盖小区，使得相邻小区信息与基站的小区信息发生重叠。譬如：基站1的小区1-4的相邻小区2-3属于基站2，其另一相邻小区3-2属于基站3。In this embodiment, the adjacent cell information added to the configuration information of the
重组控制器修改OMC后台数据库中基站控制器及基站的配置信息的先后顺序不受限制，同理OMC通过网管操作更新基站控制器和基站本地数据库配置信息的先后顺序也不受限制，但是为保证基站控制器(基站)本地数据库中被OMC更新的所有配置信息能够同步生效，当OMC更新完毕基站控制器(基站)本地数据库中的配置信息后，本领域技术人员可根据现有方式，自动触发OMC或人工触发OMC发送控制命令至基站控制器(基站)，使基站控制器(基站)本地数据库中被更新的所有配置信息同步生效，基站根据本地数据库中归属基站控制器通信地址接入新的归属基站控制器。The order in which the reorganization controller modifies the configuration information of the base station controller and the base station in the OMC background database is not limited. Similarly, the order in which the OMC updates the configuration information of the base station controller and the local database of the base station through network management operations is also not limited. However, to ensure All configuration information updated by the OMC in the local database of the base station controller (base station) can take effect synchronously. After the OMC has updated the configuration information in the local database of the base station controller (base station), those skilled in the art can automatically trigger the The OMC or manually triggers the OMC to send a control command to the base station controller (base station), so that all the updated configuration information in the local database of the base station controller (base station) will take effect synchronously, and the base station will access the new one according to the communication address of the base station controller in the local database. Belongs to the base station controller.
实施例二Embodiment two
本实施例采用基站与基站控制器间心跳协议检测基站控制器的运行状态，以代替实施例一采用重组控制器检测基站控制器的运行状态的方式。In this embodiment, the heartbeat protocol between the base station and the base station controller is used to detect the operation state of the base station controller, instead of the method of using the recombined controller to detect the operation state of the base station controller in the first embodiment.
譬如，基站1通过其与基站控制器1间的心跳协议监视基站控制器1的运行状态，当基站控制器1发生故障时，基站1向预设的重组控制器发出报告信息，该报告信息携带基站1的ID和基站控制器1的ID。基站1发送的报告消息中还可携带基站1期望的新的归属基站控制器2的ID。重组控制器在收到基站1的报告消息后响应基站1的报告消息。For example,
如果基站1在发送报告消息后的一定时间内接收不到重组控制器发送的报告消息的响应消息，而基站1中设置有多个重组控制器的地址信息，基站1可向其它重组控制器发送报告信息，以此类推直到得到一重组控制器响应消息。如果基站1向所有的重组控制器发送报告信息后，都没有接收到重组控制器发送的响应消息，则基站1停止接入其它的基站控制器。If
当重组控制器对基站1的报告信息进行响应后，重组控制器将配置数据库中基站控制器1的状态更新为不可用，防止故障基站控制器1被重选为其它基站的归属基站控制器。After the reorganization controller responds to the report information of the
如果基站1的报告信息中携带了期望的新的归属基站控制器2的ID，重组控制器更新完毕基站控制器1的状态后，重组控制器可以先在配置数据库中查询基站1期望的新的归属基站控制器2的状态是否可用，如果基站控制器2的状态为可用，则重组控制器选择基站控制器2为基站1的新的归属基站控制器，重组控制器根据基站控制器1的ID，在配置数据库中继续查询受基站控制器1控制的基站ID。If the report information of
仍以表1-表6中的内容为例，重组控制器查询的结果为基站控制器1控制的基站还包括基站2、基站3。若基站2、基站3的第一备选基站控制器3的状态为可用，则重组控制器选择基站控制器3为基站2和基站3的新的归属基站控制器。Still taking the content in Table 1-Table 6 as an example, the query result of the reorganization controller is that the base stations controlled by the
重组控制器根据基站控制器2、基站控制器3的ID，查询基站控制器2和基站控制器3的通信地址，以及根据基站1、基站2、基站3的ID查询基站1、基站2、基站3的配置信息及相邻小区信息。The recombination controller queries the communication addresses of
重组控制器获得上述信息后，通过X3接口，将OMC中后台数据库中基站1的归属基站控制器通信地址修改为基站控制器2的通信地址，并将基站1的ID、公共信息、小区信息、相邻小区信息增加在OMC后台数据库存储的基站控制器2的配置信息中，再由OMC通过X1A和X1B接口进行网管操作，同步更新基站控制器2和基站1的本地数据库中的配置信息。重组控制器以同样的方式，将OMC中存储的基站2、基站3的归属基站控制器通信地址修改为基站控制器3的通信地址，将基站2、基站3的ID、公共信息、小区信息、及基站2、基站3的相邻小区信息增加在OMC后台数据库存储的基站控制器3的配置信息中，再由OMC更新基站控制器3和基站2、基站3本地数据库中的配置信息。OMC完成基站控制器2、基站控制器3、基站1、基站2、基站3的本地数据库中配置信息的更新后，OMC仍通过人工触发或自动触发的方式发送控制命令，使基站控制器2本地数据库中被修改的配置信息同步生效。同理，OMC使基站控制器3、基站1、基站2、基站3各自的本地数据库中配置信息同步生效。基站1接入基站控制器2；基站2、基站3接入基站控制器3。After the reorganization controller obtains the above information, through the X3 interface, the communication address of the base station controller belonging to the
根据图6及表4的内容，基站控制器2增加的相邻小区信息为：2-1，2-3，3-1，3-2；基站控制器3增加的相邻小区信息为：1-2，1-3，1-4，4-1，4-2，4-3。According to the content of Fig. 6 and Table 4, the adjacent cell information that
本实施例中，如果基站1发送的报告信息中没有携带期望的新的基站控制器ID，重组将基站控制器1在配置数据库中的状态更新为不可用，并根据报告消息中的基站控制器1的ID查询到受基站控制器1控制的基站2、基站3的ID，由重组控制器按照本实施例上述内容揭示的方法，为基站1、基站2、基站3选择基站控制器3作为新的归属基站控制器、修改OMC后台数据库中存储的基站控制器配置信息及基站配置信息。OMC亦采取相同方法，通过接口X1A和X1B同步更新基站控制器和基站本地数据库信息，并触发基站控制器和基站本地数据库被修改的配置信息生效，基站按照更新后配置信息中的归属基站控制器通信地址接入新的归属基站控制器，继续提供服务。In this embodiment, if the report information sent by the
实施例三：Embodiment three:
仍以表1-表6的内容为例，在图3的无线接入网络架构中，网管人员需要将某个或某些基站重新连接到其它基站控制器时，网管人员在OMC的人机界面上输入要改变归属关系的基站ID、及其归属基站控制器ID、和期望的新的归属基站控制器ID，OMC通过接口X3发出重组命令至重组控制器。其中，OMC发送的重组命令必须携带有：要改变归属关系的基站ID，原归属基站控制器ID和期望的新的归属基站控制器ID。Still taking the contents of Table 1-Table 6 as an example, in the wireless access network architecture of Figure 3, when the network administrator needs to reconnect one or some base stations to other base station controllers, the network administrator will Input the ID of the base station whose ownership relationship is to be changed, its home base station controller ID, and the desired new home base station controller ID, and the OMC sends a reorganization command to the reorganization controller through the interface X3. Wherein, the reorganization command sent by the OMC must carry: the ID of the base station whose ownership relationship is to be changed, the ID of the original base station controller and the expected new ID of the base station controller.
例如，当网管人员需要将无线接入网络中的基站1的原归属基站控制器1修改为新的归属基站控制器2时，如图7所示，网管人员通过OMC人机界面输入：基站1的ID，原归属基站控制器1的ID，及期望的新的归属基站控制器2的ID。OMC通过X3接口发出重组命令消息给重组控制器，重组命令消息携带有基站1的ID，基站控制器1的ID和基站控制器2的ID。For example, when the network administrator needs to modify the original home
重组控制器根据重组命令消息中的基站控制器2的ID，检查基站控制器2在配置数据库中的状态是否可用。如果基站控制器2的状态为可用，则重组控制器选择基站控制器2为基站1新的归属基站控制器，并查询基站控制器2通信地址。The reorganization controller checks whether the status of the
若基站控制器2的状态为不可用，重组控制器可根据实施例一揭示的方式，根据基站1的ID，在配置数据库中查询基站1备选基站控制器及状态，选择可用状态下的备选基站控制器3作为基站1的新的归属基站控制器。If the state of the
在本实施例中，期望的基站控制器2的状态为可用，则重组控制器选择基站控制器2作为新的归属基站控制器。In this embodiment, the desired state of the
重组控制器在配置数据库中查询基站1的公共信息和小区信息，以及基站1各小区的相邻小区信息，并通过接口X3将基站1的小区ID、信令面通信地址、用户面通信地址、小区ID、频点等配置信息，以及基站1的相邻小区信息从OMC存储的基站控制器1的配置信息中删除，并将基站1的上述信息增加在OMC存储的基站控制器2的配置信息中。参照图6及表4的内容，基站1的相邻小区信息为，小区1-1，1-2，1-3，1-4的相邻小区2-1，2-3，3-1，3-2。The reorganization controller queries the public information and cell information of
重组控制器根据查询的基站控制器2的通信地址，将OMC存储的基站1的归属基站控制器通信地址修改为基站控制器2的通信地址。再由OMC通过接口X1A的网管操作更新基站控制器1和基站控制器2的本地数据库配置信息，并通过接口X2A的网管操作，同步更新基站1的本地数据库配置信息。OMC触发基站控制器1、基站控制器2、基站1本地数据库中被修改的配置信息同步生效。基站1接入基站控制器2，继续提供服务。According to the inquired communication address of the
实施例四：Embodiment four:
参照表1-表6、图3及图8所示的内容，网管人员在重组控制器的人机界面上输入要改变归属关系的基站ID，原归属基站控制器ID和期望的新的归属基站控制器ID给重组控制器。本实施例与实施例三的唯一区别在于，省略了实施例三揭示的由OMC通过接口X3发送重组命令消息至重组控制器的步骤。而其它实现无线接入网络重组的过程与实施例三完全一致。Referring to the content shown in Table 1-Table 6, Figure 3 and Figure 8, the network administrator enters the ID of the base station to change the ownership relationship on the man-machine interface of the reorganization controller, the ID of the original base station controller and the desired new base station Controller ID to reassemble the controller. The only difference between this embodiment and the third embodiment is that the step disclosed in the third embodiment that the OMC sends the reorganization command message to the reorganization controller through the interface X3 is omitted. Other processes for realizing wireless access network reorganization are completely consistent with those in
实施例五：Embodiment five:
参照图4及表1-表6中的内容，图4的无线接入网络结构中，重组控制器合设于OMC中，重组控制器与OMC间的接口X3为内部接口。Referring to Figure 4 and Table 1-Table 6, in the wireless access network structure of Figure 4, the reorganization controller is integrated in the OMC, and the interface X3 between the reorganization controller and the OMC is an internal interface.
在图4的架构中，无线接入网络主动检测网络中的失效基站控制器时，按照实施例一和实施例二揭示的方法，由重组控制器或基站1，通过与基站控制器1间的心跳协议检测基站控制器1的状态。当基站控制器1失效时，重组控制器更新基站控制器1的状态为不可用，并为基站1选择新的归属基站控制器。In the architecture shown in Figure 4, when the radio access network actively detects a failed base station controller in the network, according to the method disclosed in
由于图4的架构中，重组控制器与OMC间的接口X3为内部接口。因而，如图9所示，本实施例与实施例一、实施例二的唯一区别在于，重组控制器通过内部接口X3修改OMC后台数据库中的配置信息。而其它实现无线接入网络重组的过程与实施例一、实施二完全一致。In the architecture of FIG. 4 , the interface X3 between the reorganization controller and the OMC is an internal interface. Therefore, as shown in FIG. 9 , the only difference between this embodiment and
需要说明的是，在图4的架构中，由于重组控制器已经合设于OMC，因而，当网管人员需要改变无线接入网络中基站的归属关系，将基站接入其它基站控制器时，可采用实施例四揭示的方法实现无线接入网络的重组。It should be noted that, in the framework of Figure 4, since the reorganization controller has been co-installed in the OMC, when the network administrator needs to change the ownership relationship of the base stations in the wireless access network and connect the base stations to other base station controllers, they can The method disclosed in the fourth embodiment is used to realize the reorganization of the wireless access network.
实施例六：Embodiment six:
在图3、图4所示无线接入网络架构还存在其它特殊实施方式。譬如，无线接入网络的建设初期，无线接入网络中还未建设OMC，如图10所示：There are other special implementations in the wireless access network architecture shown in FIG. 3 and FIG. 4 . For example, in the initial stage of wireless access network construction, the OMC has not yet been built in the wireless access network, as shown in Figure 10:
在图10所示的网络架构中，当无线接入网络还未设置OMC时，当无线接入网络主动检测失效的基站控制器时，仍通过重组控制器或基站1，与基站控制器1间的心跳协议检测到基站控制器1的运行状态，当检测到基站控制器1失效时，重组控制器根据基站控制器1的ID查询到受其控制的基站1、基站2、基站3，并根据备选基站控制器信息选择新的归属基站控制器3后，如图11所示，由重组控制器直接通过接口X2A修改基站控制器3的本地数据库的配置信息。In the network architecture shown in Figure 10, when the wireless access network has not set up OMC, when the wireless access network actively detects the failed base station controller, it still communicates with the
图10所示的网络架构中，当需要主动改变基站的归属基站控制器时，如图11所示，网管人员在重组控制器的人机界面输入基站1的ID，原归属基站控制器1的ID，及期望的新的归属基站控制器2的ID。重组控制器直接通过接口X2A将基站1的小区ID、信令面通信地址、用户面通信地址、小区ID、频点等配置信息，以及将基站1的相邻小区信息从基站控制器1的本地数据库的配置信息中删除，将基站1的上述信息增加在基站控制器2本地数据库的配置信息中。In the network architecture shown in Figure 10, when it is necessary to actively change the base station controller of the base station, as shown in Figure 11, the network administrator enters the ID of
重组控制器修改完毕基站控制器1和基站控制器2的本地数据库的配置信息后，基站控制器2已经准备好连接基站1。由重组控制器控制器通过接口X2B向基站1发出接入命令，该接入命令中携带基站控制器2的通信地址(基站控制器2的信令面通信地址以及用户面通信地址)，基站1接收到重组控制器的接入命令后，向重组控制器发出响应信息，然后接入基站控制3并开始提供服务。After the reorganization controller modifies the configuration information of the local databases of the
基站控制器2准备好连接基站1时，也可由基站控制器2向基站1发出接入信令，同样该接入信令中携带基站控制器2的通信地址，基站1接收到基站控制器的命令后，向基站控制器2发出响应消息，然后接入基站控制器2。When the
因而可见，本实施例分别与实施例一、实施例二、实施例四的唯一区别均为：由重组控制器通过接口X2A修改新的基站控制器的本地数据库的配置信息，再由重组控制器或新的归属基站控制器通知基站接入新的归属基站控制器，避免了无线接入网络因为没有设置OMC而造成的无法依靠信息同步，修改基站控制器和基站的本地数据库中配置信息的问题。为保证基站与基站控制器的信息同步，基站可进行重新启动或者重新初始化后再继续提供服务。Therefore, it can be seen that the only difference between this embodiment and
本实施例中，重组控制器或基站检测失效基站控制器的方法、重组控制器更新基站控制器状态的方法、重组控制器查询备选基站控制器的方法与实施例一、实施例二揭示相应方法相同，因而不再重复叙述，具体内容请参见实施例一和实施例二的内容。In this embodiment, the method for the reorganization controller or the base station to detect the failed base station controller, the method for the reorganization controller to update the status of the base station controller, and the method for the reorganization controller to query the candidate base station controller are corresponding to those disclosed in
关于本发明需要特别说明的是，在图3及实施例一、实施例二、及实施例三中，基站控制器和基站的本地数据库中配置信息的更新方法，虽然采用了通过重组控制器修改OMC后台数据库中的配置信息，再由OMC基站控制器和基站的本地数据库中配置信息的方式。该方式只是一种较佳的实现方式，其实，在图3及实施例一、实施例二、及实施例三中，采用重组控制器直接修改设备(重组控制器/基站)的本地配置信息并触发无线接入网络重组的技术方案也是可行的，但是该方式绕开了OMC改动设备配置信息，可能导致OMC后台数据库存储的配置信息与设备本地的配置信息不一致，OMC后台数据库存储的归属关系与实际的归属关系不一致；从而使网络管理人员无法掌握网上设备运行的实际情况，对于网络的运行维护并不理想。What needs to be specially explained about the present invention is that in Fig. 3 and
此外，在本实施例中，若网管人员操作重组控制器的人机界面以改变基站的归属关系时，网关人员在重组控制器的人机界面上输入要改变归属关系的基站ID，原归属基站控制器ID和期望的新的归属基站控制器ID给重组控制器的方法、重组控制器修改基站原归属基站控制器配置信息和新的归属基站控制器的配置信息，与实施例四一致，因而此处不再重复叙述，具体内容请参见实施例四。In addition, in this embodiment, if the network administrator operates the man-machine interface of the reorganization controller to change the affiliation of the base station, the gateway personnel input the ID of the base station whose affiliation is to be changed on the man-machine interface of the reorganization controller, and the original affiliation of the base station The controller ID and the desired new home base station controller ID are given to the reorganization controller, and the reorganization controller modifies the configuration information of the original home base station controller of the base station and the configuration information of the new home base station controller, which is consistent with
在此需要强调的是，本发明是为了实现无线接入网络自动重组的功能。本发明采用的IP技术作为无线接入网络传输网络技术只是本发明实现的前提之一，本发明的实施并非仅限于采用IP技术作为无线接入网络传输网络技术。只要是能够支持路由功能的传输网络技术都可以应用此发明。What needs to be emphasized here is that the present invention is to realize the function of automatic reorganization of the wireless access network. The IP technology used in the present invention as the wireless access network transmission network technology is only one of the prerequisites for the realization of the present invention, and the implementation of the present invention is not limited to the use of IP technology as the wireless access network transmission network technology. This invention can be applied to any transmission network technology that can support the routing function.
本发明不仅可以应用于基于IP传输的第三代移动通信网络，还可应用于演进的第三代移动通信网络。即使演进的第三代移动通信网络不再使用基站控制器和基站等技术，或者基站控制器与核心网设备合并成为一个新的设备，只要无线接入网络分为两层网元结构，并且第二层网元与第一层网元是一对多的关系，那么都适用于发明。The present invention can be applied not only to the third generation mobile communication network based on IP transmission, but also to the evolved third generation mobile communication network. Even if the evolved third-generation mobile communication network no longer uses technologies such as base station controllers and base stations, or the base station controller and core network equipment are merged into a new device, as long as the wireless access network is divided into two layers of network elements, and the first The two-layer network element and the first-layer network element have a one-to-many relationship, so both are applicable to the invention.
本发明的有益效果在于，能够自动将原无线网络子系统的基站划到其它可以正常工作的基站控制器的控制下，使得基站能够为原无线网络子系统覆盖范围内的用户继续提供业务，除降低基站控制器故障导致的中断服务时间外，避免了人工修改配置信息及切换基站，降低了系统的操作复杂度，增强了系统的可靠性及工作的效率。The beneficial effect of the present invention is that the base station of the original wireless network subsystem can be automatically assigned to the control of other base station controllers that can work normally, so that the base station can continue to provide services for users within the coverage of the original wireless network subsystem, except In addition to reducing the service interruption time caused by the failure of the base station controller, manual modification of configuration information and switching of base stations are avoided, the operation complexity of the system is reduced, and the reliability and work efficiency of the system are enhanced.
以上实施例仅用于说明本发明的实施过程，并非用于限定本发明的保护范围。The above embodiments are only used to illustrate the implementation process of the present invention, and are not used to limit the protection scope of the present invention.
