本发明涉及网络通信技术领域，特别涉及一种设置小区邻区列表的方法、系统和装置。The present invention relates to the technical field of network communication, in particular to a method, system and device for setting a neighborhood list of a cell.
背景技术Background technique
面对Wi-Fi(Wireless Fidelity，无线保真技术)和WiMAX(WorldInteroperability for Microwave Access，全球微波接入互操作性)的热点覆盖竞争压力，移动运营商正在寻求增强的2G(Second Generation，第二代移动通信技术)或3G(Third Generation，第三代移动通信技术)的覆盖解决方案，以满足家庭和小型商务的需要，HNB(Home NodeB，家用基站)是目前最有潜力的低成本接入技术。Faced with the hotspot coverage competition pressure of Wi-Fi (Wireless Fidelity, wireless fidelity technology) and WiMAX (World Interoperability for Microwave Access, global microwave access interoperability), mobile operators are seeking enhanced 2G (Second Generation, second Generation mobile communication technology) or 3G (Third Generation, third-generation mobile communication technology) coverage solutions to meet the needs of families and small businesses, HNB (Home NodeB, home base station) is currently the most potential low-cost access technology.
HNB可以在本地处理蜂窝移动电话通话，然后通过DSL(Digital SubscriberLoop，数字用户环路)或有线调制解调器等宽带将其传输到运营商的核心网络，如图1所示，这样不仅降低了对多个手机、双模终端的需求，而且还降低了扩大网络覆盖和容量的资金投入。HNB can process cellular mobile phone calls locally, and then transmit them to the operator's core network through broadband such as DSL (Digital Subscriber Loop) or cable modem, as shown in Figure 1, which not only reduces the need for multiple The demand for mobile phones and dual-mode terminals also reduces the capital investment for expanding network coverage and capacity.
目前各移动通信厂商都在积极讨论HNB在UMTS(Universal MobileTelecommunications System，通用移动通信系统)系统及其各个演进版本HSPA+(High Speed Packet Access Evolution，高速分组接入演进)、LTE(LongTerm Evaluation，长期网络演进)中的实现方案。At present, various mobile communication manufacturers are actively discussing HNB in the UMTS (Universal Mobile Telecommunications System, Universal Mobile Communications System) system and its various evolution versions HSPA+ (High Speed Packet Access Evolution, High Speed Packet Access Evolution), LTE (Long Term Evaluation, long-term network Evolution) in the implementation scheme.
UMTS系统是采用WCDMA空中接口技术的第三代移动通信系统。UMTS系统采用了与第二代移动通信系统类似的结构，包括RAN(Radio AccessNetwork，无线接入网络)和CN(Core Network，核心网络)。其中RAN用于处理所有与无线有关的功能，而CN处理UMTS系统内所有的话音呼叫和数据连接，并实现与外部网络的交换和路由功能。CN从逻辑上分为CS(CircuitSwitched Domain，电路交换域)和PS(Packet Switched Domain，分组交换域)。UTRAN(Universal Terrestrial Radio Access Network，通用地面无线接入网)、CN与UE(User Equipment，用户设备)构成了整个UMTS系统，UMTS系统的系统结构如图2所示。UMTS system is the third generation mobile communication system using WCDMA air interface technology. The UMTS system adopts a structure similar to that of the second-generation mobile communication system, including RAN (Radio Access Network, wireless access network) and CN (Core Network, core network). Among them, RAN is used to handle all wireless-related functions, while CN handles all voice calls and data connections in the UMTS system, and realizes switching and routing functions with external networks. CN is logically divided into CS (Circuit Switched Domain, Circuit Switched Domain) and PS (Packet Switched Domain, Packet Switched Domain). UTRAN (Universal Terrestrial Radio Access Network, Universal Terrestrial Radio Access Network), CN and UE (User Equipment, User Equipment) constitute the entire UMTS system, and the system structure of the UMTS system is shown in Figure 2.
在UTRAN中，Node B是WCDMA(Wideband Code Division MultipleAccess，宽带码分多址接入)系统的基站，包括无线收发信机和基带处理部件，通过标准的Iub接口和RNC(Radio Network Controller，无线网络控制器)互连。RNC主要完成连接的建立和断开、切换、宏分集合并以及无线资源管理控制等功能。In UTRAN, Node B is the base station of the WCDMA (Wideband Code Division Multiple Access, wideband code division multiple access) system, including wireless transceivers and baseband processing components, through the standard Iub interface and RNC (Radio Network Controller, wireless network controller) interconnection. The RNC mainly completes functions such as connection establishment and disconnection, handover, macro-diversity combination, and radio resource management control.
CN负责与其他网络的连接和对UE的通信和管理。其中，MSC(MobileSwitch Center，移动交换中心)/VLR(Visitor Location Register，访问位置寄存器)是WCDMA核心网CS域功能节点，通过Iu_CS接口与UTRAN相连，提供CS域的呼叫控制、移动性管理、鉴权和加密等功能；SGSN(Serving GPRSSupport Node，服务GPRS支持节点)是WCDMA核心网PS域功能节点，通过Iu_PS接口与UTRAN相连，提供PS域的路由转发、移动性管理、会话管理、鉴权和加密等功能。CN is responsible for connection with other networks and communication and management for UE. Among them, MSC (Mobile Switch Center, mobile switching center)/VLR (Visitor Location Register, visit location register) is a WCDMA core network CS domain function node, connected to UTRAN through the Iu_CS interface, providing CS domain call control, mobility management, authentication Authorization and encryption functions; SGSN (Serving GPRS Support Node, serving GPRS support node) is a WCDMA core network PS domain function node, connected to UTRAN through the Iu_PS interface, providing PS domain routing and forwarding, mobility management, session management, authentication and Encryption and other functions.
UTRAN和CN之间的接口统称为Iu接口，包括Iu_CS接口和Iu_PS接口。Iu接口的作用是使通过Iu接口相连接的UTRAN与CN可由不同的设备制造商提供。连接RNC之间的接口是Iur接口，用于对UE的移动进行管理，例如：UE在不同的RNC之间进行切换时，UE所有的数据都是通过Iur接口从正在工作的RNC传到候选RNC，如图3所示。The interface between UTRAN and CN is collectively referred to as Iu interface, including Iu_CS interface and Iu_PS interface. The function of the Iu interface is to enable the UTRAN and CN connected through the Iu interface to be provided by different equipment manufacturers. The interface connecting the RNCs is the Iur interface, which is used to manage the mobility of the UE. For example, when the UE switches between different RNCs, all data of the UE is transmitted from the working RNC to the candidate RNC through the Iur interface. ,As shown in Figure 3.
随着3G HNB的密集部署，3G HNB的移动性成为了需要考虑的重要问题，同时3G HNB还需要兼容传统的3G终端。现有技术中，一个传统终端无法识别一个小区的信号是来自HNB，还是宏小区。并且，一般情况下，最多可把一个小区的32个相邻小区设置到这个小区的邻区列表中。现有技术中，配置邻区一般是在网规时配置，配置邻区时主要考虑的因素是地理上的相邻与覆盖因素，不会考虑设备的类型等因素。如图4所示，为HNB与3G宏小区共同部署时的场景：UE1是Idle(空闲)状态；UE2是Active(激活)状态。HNB A和HNB B是两个HNB，它们在一个3G宏小区C覆盖范围内部署。With the intensive deployment of 3G HNBs, the mobility of 3G HNBs has become an important issue to be considered. At the same time, 3G HNBs also need to be compatible with traditional 3G terminals. In the prior art, a traditional terminal cannot identify whether a signal of a cell comes from an HNB or a macro cell. And, generally, a maximum of 32 adjacent cells of a cell can be set in the cell's neighbor list. In the prior art, the configuration of neighboring cells is generally performed during network planning, and the main considerations in configuring neighboring cells are geographical proximity and coverage factors, and factors such as equipment types are not considered. As shown in Fig. 4, it is a scenario when the HNB and the 3G macro cell are co-deployed: UE1 is in the Idle (idle) state; UE2 is in the Active (activated) state. HNB A and HNB B are two HNBs, which are deployed within the coverage of a 3G macro cell C.
按照现有技术，在正常配置的情形下，HNB A的邻区列表包括HNB B和3G宏小区C，HNB B的邻区列表包括HNB A和3G宏小区C，3G邻小区C的邻区列表包括HNB A和HNB B。According to the existing technology, in the case of normal configuration, the neighbor list of HNB A includes HNB B and 3G macro cell C, the neighbor list of HNB B includes HNB A and 3G macro cell C, and the neighbor list of 3G neighbor cell C Including HNB A and HNB B.
考虑到UE的两个状态Idle和Active，将分成两个场景对现有技术的缺点进行描述：Considering the two states of the UE, Idle and Active, the disadvantages of the prior art will be described in two scenarios:
1、场景A：UE处于Idle状态1. Scenario A: UE is in Idle state
如图4所示，一个驻留在CSG(Closed Subscriber Group，封闭用户组)HNBA的具有HNB A访问权限的合法UE1，离开了HNB A的覆盖，刚好移动到了另一个CSG HNB B的覆盖中。而HNB B可能是这个UE不具有接入权限的CSGHNB，或者是这个UE具有接入权限的CSG HNB，或者是完全开放、任何UE都有权限接入的Open HNB。As shown in Figure 4, a legitimate UE1 residing in a CSG (Closed Subscriber Group, Closed Subscriber Group) HNBA with access rights to HNB A leaves the coverage of HNB A and just moves to the coverage of another CSG HNB B. The HNB B may be a CSGHNB that the UE does not have access rights to, or a CSG HNB that the UE has access rights to, or an Open HNB that is completely open and that any UE has access rights to.
(a)如果HNB B为UE1不具有接入权限的CSG HNB，则将来发起呼叫时，HNB B将会拒绝UE1，从而使延迟时间增加，所以这种情况一定要避免。(a) If HNB B is a CSG HNB that UE1 does not have access rights to, HNB B will reject UE1 when initiating a call in the future, thus increasing the delay time, so this situation must be avoided.
(b)UE1从自己的CSG HNB离开后，即刚刚离开自己的住所，UE1已经意识到将离开自己的HNB环境，意味着UE1对接入宏小区是有心理准备的。如果HNB B为任何UE都有权限接入的Open HNB，并且是用户设备，则该HNB不一定能保证给UE1提供可靠的服务质量。例如：如果该目标Open HNB是家用的，那么当这个Open HNB突然关机时，将会导致UE1突然失去驻留的目标小区。如果目标Open HNB是商业设施里的，那么可能无法保证后续的服务质量。另外，由于HNB的覆盖范围比较小，UE可能只是短暂经过一个HNB又进入另一个HNB，即UE会频繁的更换驻留小区。而如果这些目标HNB是不同的RA(Routing Area，路由区)/LA(Location Area，位置区)，UE又会频繁的发起RAU(Routing Area Update，路由区更新)/LAU(Location Area Update，位置区更新)。因此，这种情况最好避免。(b) After UE1 left its own CSG HNB, that is, just left its own residence, UE1 has realized that it will leave its own HNB environment, which means that UE1 is psychologically prepared to access the macro cell. If HNB B is an Open HNB that any UE has the right to access, and is a user equipment, the HNB may not be able to guarantee reliable service quality for UE1. For example: if the target Open HNB is for home use, when the Open HNB suddenly shuts down, UE1 will suddenly lose the target cell where it resides. If the target Open HNB is in a commercial facility, subsequent service quality may not be guaranteed. In addition, due to the relatively small coverage of the HNB, the UE may only pass through one HNB for a short time and then enter another HNB, that is, the UE will frequently change the cell it resides on. And if these target HNBs are different RA (Routing Area, routing area)/LA (Location Area, location area), UE will frequently initiate RAU (Routing Area Update, routing area update)/LAU (Location Area Update, location district update). Therefore, this situation is best avoided.
(c)如果HNB B为UE1具有接入权限的CSG HNB。在这种场景下，应该允许该CSG HNB作为UE1优先驻留的目标小区，因为一般情况下，HNB的信号要好于宏小区的信号。所以通过小区信号测量，应该优先把UE1驻留到这种CSG HNB。(c) If HNB B is a CSG HNB that UE1 has access rights to. In this scenario, the CSG HNB should be allowed to be the target cell where UE1 preferentially camps, because in general, the signal of the HNB is better than the signal of the macro cell. Therefore, through cell signal measurement, UE1 should be preferentially camped on this CSG HNB.
2、场景B：UE处于Active状态2. Scenario B: UE is in Active state
如图4所示，一个具有HNB A访问权限的正在CSG HNB A中使用业务的合法UE2，离开了HNB A的覆盖范围，刚好移动到了另一个CSG HNB B的覆盖范围中。而HNB B可能是UE2不具有接入权限的CSG HNB，或者是UE2具有接入权限的CSG HNB，或者是完全开放、任何UE都有权限接入的Open HNB。As shown in Figure 4, a legitimate UE2 with access rights to HNB A that is using services in CSG HNB A leaves the coverage of HNB A and just moves to the coverage of another CSG HNB B. The HNB B may be a CSG HNB that UE2 does not have access rights to, or a CSG HNB that UE2 has access rights to, or an Open HNB that is completely open and any UE has access rights.
在现有技术中，当UE切换时，源小区会给UE设置一个待测量的邻小区列表，UE需要向源小区上报每个小区的测量报告。由源小区负责决定UE切换到哪个目标小区。In the prior art, when the UE is handed over, the source cell sets a list of neighboring cells to be measured for the UE, and the UE needs to report a measurement report of each cell to the source cell. The source cell is responsible for deciding which target cell the UE is handed over to.
(a)如果源小区给UE2设置的某个HNB邻小区，是UE2不具有接入权限CSG HNB，从而可能导致UE2不必要的测量，甚至导致UE2切换失败。这种情况一定要避免。(a) If the source cell sets a certain HNB neighbor cell for UE2, it is a CSG HNB that UE2 does not have access rights, which may cause unnecessary measurement of UE2, and even cause handover failure of UE2. This situation must be avoided.
(b)UE2从自己的CSG HNB离开后，即刚刚离开自己的住所，UE2已经意识到将离开自己的HNB环境，意味着UE2对接入宏小区是有心理准备的。如果源小区给UE2设置的某个HNB邻小区是Open HNB，并且UE2在此时发起业务，对于UE2正在进行的通话来说，UE2更加看中的是通信质量。但是如果HNB B为任何UE都有权限接入的Open HNB，并且是用户设备，那么该HNB不一定能保证给UE2提供可靠的服务质量。例如：如果该目标Open HNB是家用的，那么当这个Open HNB突然关机时，将会导致UE2掉话。如果目标OpenHNB是商业设施里的，那么可能无法保证后续的服务质量。因此，这种情况最好避免。(b) After UE2 left its own CSG HNB, that is, just left its own residence, UE2 has realized that it will leave its own HNB environment, which means that UE2 is psychologically prepared to access the macro cell. If the HNB neighbor cell set by the source cell for UE2 is an Open HNB, and UE2 initiates a service at this time, for the ongoing call of UE2, UE2 pays more attention to the communication quality. However, if HNB B is an Open HNB that any UE has the right to access, and is a user equipment, then the HNB may not be able to guarantee reliable service quality for UE2. For example: if the target Open HNB is for home use, when the Open HNB suddenly shuts down, it will cause UE2 to drop calls. If the target OpenHNB is in a commercial facility, subsequent service quality may not be guaranteed. Therefore, this situation is best avoided.
(c)如果源小区给UE2设置的某个HNB邻小区，是UE2具有接入权限的CSG HNB。在这种场景下，应该允许该CSG HNB作为UE2优先驻留的目标小区，因为一般情况下，HNB的信号要好于宏小区的信号。所以通过小区信号测量或者切换判决，应该优先把UE切换到这种CSG HNB。因此，这种情况，需要把该CSG HNB作为UE2优先切换的目标小区。(c) If the source cell sets a certain HNB neighbor cell for UE2, it is a CSG HNB that UE2 has access rights to. In this scenario, the CSG HNB should be allowed to be the target cell where UE2 preferentially camps, because in general, the signal of the HNB is better than the signal of the macro cell. Therefore, through cell signal measurement or handover judgment, the UE should be handed over to this CSG HNB first. Therefore, in this case, the CSG HNB needs to be used as the target cell for the UE2 to handover preferentially.
因此，现有技术的缺点是：按照现有的邻区列表的配置方式，会带来UE错误驻留、切换失败、丢失驻留小区、掉话等问题。Therefore, the disadvantage of the prior art is that according to the existing configuration method of the neighbor cell list, problems such as UE camping on incorrectly, handover failure, loss of the camping cell, and call drop will be caused.

Through the embodiment of the present invention, according to the obtained cell information of the neighbor cell of the base station cell, the neighbor cell list of the base station cell is set, and the neighbor cell list of the base station cell is set in real time. The cell information of the base station can be used to update the neighbor list of the base station cell, so that the UE can successfully camp on a legal cell, improve the handover success rate, and avoid UE errors caused by the existing method of configuring the neighbor list of the base station cell Problems such as camping, handover failure, loss of the camped cell, invalid measurement, and call drop.

The base station cell mentioned in the embodiment of the present invention may be a common base station cell or a home base station HNB cell, but the embodiment of the present invention uses the HNB cell as an example for illustration.
如图5所示，为本发明实施例设置小区邻区列表的方法的流程图，具体包括以下步骤：As shown in Figure 5, it is a flowchart of a method for setting a cell neighbor list in an embodiment of the present invention, which specifically includes the following steps:
步骤S501，获取基站小区邻小区的小区信息。本发明实施例提到的基站小区可以为普通的基站小区，也可以为家用基站HNB小区，办公室基站小区，校园基站小区，但本发明实施例以家用基站HNB小区为例进行说明。在设置HNB的邻区列表之前，该HNB先获取该HNB小区邻小区的小区信息。该HNB小区邻小区的小区信息包括小区类型和小区载频中的一种或两种。该小区类型包括宏小区、HNB小区、Office NB(商用基站)小区和Campus NodeB(校园基站)小区中的一种或几种。当小区类型为非宏小区时，该小区信息还可以进一步包括Open HNB小区信息和CSG HNB小区信息中的一种或两种。当小区类型为CSG HNB小区时，该小区信息还可进一步提供CSG ID和用户列表中的一种或两种。Step S501, acquiring cell information of neighboring cells of the cell of the base station. The base station cell mentioned in the embodiment of the present invention may be a common base station cell, or a home base station HNB cell, an office base station cell, or a campus base station cell, but the embodiment of the present invention uses a home base station HNB cell as an example for illustration. Before setting the neighbor cell list of the HNB, the HNB first obtains the cell information of the neighbor cells of the HNB cell. The cell information of the adjacent cell of the HNB cell includes one or both of cell type and cell carrier frequency. The cell type includes one or more of macro cell, HNB cell, Office NB (commercial base station) cell and Campus NodeB (campus base station) cell. When the cell type is a non-macro cell, the cell information may further include one or both of Open HNB cell information and CSG HNB cell information. When the cell type is a CSG HNB cell, the cell information may further provide one or both of CSG ID and user list.
本发明实施例提供了多种获取HNB小区邻小区的小区信息的方式，可以通过Iu接口、Iur接口、Iub接口或空中接口获取该HNB小区邻小区的小区信息；或者，可以通过UE上报的测量结果获取该HNB小区邻小区的小区信息；或者，可以通过接收网络侧设备下发的小区信息获取该HNB小区邻小区的小区信息；或者，可以通过上游节点获取该HNB小区邻小区的小区信息。另外，当第一HNB小区邻小区的小区信息发生改变时，例如：当与第一HNB相邻的第二HNB开机时，第一HNB实时地获取第二HNB小区的小区信息。The embodiment of the present invention provides a variety of ways to obtain the cell information of the neighboring cells of the HNB cell, and the cell information of the neighboring cells of the HNB cell can be obtained through the Iu interface, the Iur interface, the Iub interface or the air interface; or, the measurement reported by the UE can be used As a result, the cell information of the adjacent cell of the HNB cell can be obtained; or, the cell information of the adjacent cell of the HNB cell can be obtained by receiving the cell information sent by the network side equipment; or, the cell information of the adjacent cell of the HNB cell can be obtained through an upstream node. In addition, when the cell information of the adjacent cell of the first HNB cell changes, for example: when the second HNB adjacent to the first HNB starts up, the first HNB acquires the cell information of the second HNB cell in real time.
在获取了HNB小区邻小区的小区信息之后，该HNB就可知道与该HNB相邻的每个HNB小区的小区信息、并根据其中的小区类型信息获得这些相邻的HNB与该HNB的权限关系、载频是否一致等信息。After obtaining the cell information of the adjacent cells of the HNB cell, the HNB can know the cell information of each HNB cell adjacent to the HNB, and obtain the authority relationship between these adjacent HNBs and the HNB according to the cell type information , Whether the carrier frequency is consistent and other information.
步骤S502，根据邻小区的小区信息，选择基站小区的邻小区。根据获取的邻小区的小区信息，可以选择与该HNB小区相邻的宏小区作为基站小区的邻小区；或者，只选择具有权限的CSG HNB小区作为基站小区的邻小区；或者，选择与该HNB小区相邻的宏小区以及具有权限的CSG HNB小区作为基站小区的邻小区；或者，选择与该HNB小区相邻的宏小区、具有权限的CSGHNB小区和Open HNB小区中的一种或几种作为基站小区的邻小区。Step S502, according to the cell information of the neighboring cells, select the neighboring cells of the cell of the base station. According to the obtained cell information of the adjacent cell, the macro cell adjacent to the HNB cell can be selected as the adjacent cell of the base station cell; or, only the CSG HNB cell with authority is selected as the adjacent cell of the base station cell; or, the macro cell adjacent to the HNB cell can be selected as the adjacent cell of the base station cell; The macro cell adjacent to the cell and the CSG HNB cell with authorization are used as the adjacent cells of the base station cell; or, one or more of the macro cell adjacent to the HNB cell, the CSGHNB cell with authorization, and the Open HNB cell are selected as Neighboring cells of the base station cell.
其中，选择具有权限的CSG HNB小区作为基站小区的邻小区包括以下两种情况：Among them, selecting the CSG HNB cell with authority as the neighboring cell of the base station cell includes the following two situations:
(1)当驻留在第一小区的所有用户都具有第二CSG HNB小区的权限时，在BCCH或者测量控制消息中的邻区列表中，选择该第二CSG HNB小区作为基站小区的邻小区；(1) When all users residing in the first cell have the authority of the second CSG HNB cell, select the second CSG HNB cell as the neighbor cell of the base station cell in the neighbor cell list in the BCCH or measurement control message ;
(2)当只有驻留在第一小区的部分用户具有第二CSG HNB小区的权限时，则只在该部分用户测量控制消息中的邻区列表中，选择该第二CSG HNB小区作为基站小区的邻小区。(2) When only some users residing in the first cell have the authority of the second CSG HNB cell, then only select the second CSG HNB cell as the base station cell in the neighbor cell list in the measurement control message of this part of users neighboring districts.
步骤S503，根据选择的基站小区邻小区的小区信息，设置该基站小区的邻区列表。在本发明实施例中，在选择好HNB小区的邻小区之后，根据选择的HNB小区邻小区的小区信息，HNB可以自己设置该HNB小区的邻区列表；也可以由网络侧设备根据HNB小区的小区信息以及该HNB小区邻小区的小区信息，选择合适的HNB小区的邻小区，设置HNB小区的邻区列表，然后将该邻区列表直接下发给HNB。Step S503, according to the cell information of the neighboring cells of the selected base station cell, a list of neighboring cells of the selected base station cell is set. In the embodiment of the present invention, after selecting the neighbor cell of the HNB cell, the HNB can set the neighbor cell list of the HNB cell by itself according to the cell information of the selected HNB cell neighbor cell; The cell information and the cell information of the adjacent cell of the HNB cell, select the appropriate adjacent cell of the HNB cell, set the adjacent cell list of the HNB cell, and then directly deliver the adjacent cell list to the HNB.
上述设置小区邻区列表的方法，根据获取的HNB小区邻小区的小区信息，选择该HNB小区的邻小区，然后根据选择的HNB小区邻小区的小区信息设置该HNB邻小区的邻区列表，从而可以确保UE驻留到合法的小区，提高了切换的成功率，并可保证为UE提供可靠的服务质量，避免了由于现有的配置HNB邻区列表的方式带来的UE错误驻留、切换失败、丢失驻留小区、无效测量、无法保证服务质量、掉话等问题。The above-mentioned method for setting the neighbor cell list of the cell, selects the neighbor cell of the HNB cell according to the obtained cell information of the neighbor cell of the HNB cell, and then sets the neighbor cell list of the HNB neighbor cell according to the cell information of the selected HNB cell neighbor cell, thereby It can ensure that the UE camps in a legal cell, improves the success rate of handover, and can ensure reliable service quality for the UE, avoiding UE wrong camping and handover caused by the existing way of configuring the HNB neighbor list Failure, loss of resident cell, invalid measurement, inability to guarantee service quality, call drop, etc.
如图6所示，为本发明设置小区邻区列表的方法实施例一的流程图，具体包括以下步骤：As shown in FIG. 6, the flow chart of
步骤S601，网络侧设备收集所有HNB小区的小区信息、位置信息和相邻信息中的一种或几种。这些信息是由各HNB上报给网络侧设备的。网络侧设备根据位置信息或者相邻信息可确定出各HNB的相邻关系。位置信息表明了各HNB小区的地理位置。相邻信息是各HNB小区之间在覆盖上的相邻关系。位置信息和相邻信息可能有关联，也可能没有关联。In step S601, the network side device collects one or more of cell information, location information and neighbor information of all HNB cells. These information are reported to the network side device by each HNB. The network side device can determine the neighbor relationship of each HNB according to the location information or neighbor information. The location information indicates the geographic location of each HNB cell. The neighbor information is the neighbor relationship in coverage between each HNB cell. Location information and neighborhood information may or may not be associated.
该HNB小区邻小区的小区信息包括小区类型和小区载频中的一种或两种。该小区类型包括宏小区、HNB小区、Office NB小区和Campus NodeB小区中的一种或几种。当小区类型为非宏小区时，该小区信息还可以进一步包括Open HNB小区信息和CSG HNB小区信息中的一种或两种。当小区类型为CSG HNB小区时，该小区信息还可进一步提供CSG ID和用户列表中的一种或两种。The cell information of the adjacent cell of the HNB cell includes one or both of cell type and cell carrier frequency. The cell type includes one or more of macro cells, HNB cells, Office NB cells, and Campus NodeB cells. When the cell type is a non-macro cell, the cell information may further include one or both of Open HNB cell information and CSG HNB cell information. When the cell type is a CSG HNB cell, the cell information may further provide one or both of CSG ID and user list.
当HNB开机启动或者由于其他条件的触发，例如：网络侧设备检测到该HNB小区邻小区的小区信息发生变化后，网络侧设备把与该HNB小区相邻的小区的小区信息下发给该HNB。该网络侧设备可以是OMC(Operation andMaintenance Center，操作维护中心)、SGSN、MME(Mobility ManagementEntity，移动管理实体)、RNC、安全网关等实体。这样，该HNB就可知道与该HNB小区相邻的每个HNB小区的小区信息、并根据其中的小区类型信息获得这些相邻的HNB小区与该HNB小区的权限关系、载频是否一致等信息。When the HNB is turned on or triggered by other conditions, for example: after the network side equipment detects that the cell information of the adjacent cell of the HNB cell has changed, the network side equipment sends the cell information of the adjacent cell of the HNB cell to the HNB . The network side device may be entities such as OMC (Operation and Maintenance Center, operation and maintenance center), SGSN, MME (Mobility Management Entity, mobile management entity), RNC, and security gateway. In this way, the HNB can know the cell information of each HNB cell adjacent to the HNB cell, and obtain information such as the authority relationship between these adjacent HNB cells and the HNB cell, whether the carrier frequency is consistent, etc. .
步骤S602，HNB根据邻小区的载频信息，优化该HNB小区邻小区的配置。由于对于同频的HNB，可以实现软切换，对于异频的HNB，只能采用硬切换，而硬切换相比较软切换而言，用户业务的连续性不是很好。所以可以根据邻小区信息中的载频信息，以及实际情况与需要优化该HNB小区邻小区的配置。例如，如果一个HNB小区有很多同频的邻小区，则可以只选择同频的邻小区作为该HNB小区的邻小区，而不选择异频的邻小区作为该HNB小区的邻小区。In step S602, the HNB optimizes the configuration of the neighboring cells of the HNB cell according to the carrier frequency information of the neighboring cells. For HNBs with the same frequency, soft handover can be implemented, and for HNBs with different frequencies, only hard handover can be used. Compared with soft handover, hard handover has poor service continuity for users. Therefore, the configuration of the adjacent cells of the HNB cell can be optimized according to the carrier frequency information in the adjacent cell information, as well as actual conditions and needs. For example, if an HNB cell has many neighboring cells of the same frequency, only the neighboring cells of the same frequency may be selected as the neighboring cells of the HNB cell, and the neighboring cells of different frequencies may not be selected as the neighboring cells of the HNB cell.
步骤S603，根据HNB小区邻小区的小区信息，选择该HNB小区的邻小区，并根据选择的HNB小区邻小区的小区信息设置该HNB小区的邻区列表。本发明实施例提供了4种优化邻区列表设置的方法，具体为：Step S603: Select a neighboring cell of the HNB cell according to the cell information of the neighboring cell of the HNB cell, and set a neighboring cell list of the HNB cell according to the cell information of the selected neighboring cell of the HNB cell. The embodiment of the present invention provides 4 methods for optimizing the setting of the neighbor list, specifically:
方法1：只设置与该HNB小区相邻的宏小区作为邻区。Method 1: Only set the macro cell adjacent to the HNB cell as the adjacent cell.
这样在该HNB小区的邻区列表里就不会出现其它任何HNB的小区信息。如图4所示，如果只设置与HNB A相邻的宏小区的小区信息，则在HNB A的BCCH(Broadcast Control Channel，广播控制信道)广播信道中就不会有HNB B的小区信息。因此，处于Idle状态的UE1，就不会去测量HNB B的小区信号，所以也不会驻留到HNB B的小区中去。从而解决了由于HNB B拒绝UE接入带来的延时增加，以及当HNB B为任何UE都有权限接入的OpenHNB时，不能给UE1提供可靠的服务质量，并有可能使UE1频繁地发起RAU/LAU等问题。In this way, the cell information of any other HNB will not appear in the neighbor cell list of the HNB cell. As shown in Figure 4, if only the cell information of the macro cell adjacent to HNB A is set, there will be no cell information of HNB B in the BCCH (Broadcast Control Channel, Broadcast Control Channel) broadcast channel of HNB A. Therefore, UE1 in the Idle state will not measure the cell signal of HNB B, so it will not camp in the cell of HNB B. Therefore, it solves the delay increase caused by HNB B's rejection of UE access, and when HNB B is an OpenHNB that any UE has the right to access, it cannot provide reliable service quality to UE1, and it may cause UE1 to frequently initiate RAU/LAU and other issues.
对处于Actice状态的UE2来说，在HNB A给UE2发送的测量报告中，也不会携带HNB B的小区信息，这样UE2就不会试图切换到HNB B中去，从而解决由于UE2不具有HNB B的接入权限导致的无效测量、切换失败，以及当HNB B为任何UE都有权限接入的Open HNB时，不能给UE2提供可靠的服务质量，并可能导致UE2掉话等问题。For UE2 in the Active state, the measurement report sent by HNB A to UE2 will not carry the cell information of HNB B, so that UE2 will not try to switch to HNB B, so as to solve the problem that UE2 does not have HNB Invalid measurement and handover failure caused by B's access rights, and when HNB B is an Open HNB that any UE has access to, it cannot provide reliable service quality to UE2, and may cause UE2 to drop calls and other problems.
方法2：只设置具有权限的CSG HNB小区作为邻区。Method 2: Only set the authorized CSG HNB cell as a neighboring cell.
如图7所示，在校园部署方式中，大量的HNB小区连续部署，并且这些HNB小区的覆盖是完整的，即使没有宏小区的信号，也可以无缝地给整个校园提供服务。也就是说，在校园覆盖的非边缘地带，每个HNB小区的周围区域都被其他相同的CSG HNB小区所覆盖，因此，在整个校园网络中，非边缘HNB小区覆盖了大多数区域。在这种情况下，UE在非边缘HNB小区的覆盖范围中移动时，可以只通过HNB小区接入网络使用业务，不再使用宏基站。通过只设置具有权限的CSG HNB小区的小区信息可以避免UE驻留到宏小区，因为非边缘HNB小区不会通过邻区列表把宏小区的小区信息告诉UE。As shown in Figure 7, in the campus deployment mode, a large number of HNB cells are deployed continuously, and the coverage of these HNB cells is complete, even if there is no macro cell signal, they can seamlessly provide services to the entire campus. That is to say, in the non-edge area of campus coverage, the surrounding area of each HNB cell is covered by other identical CSG HNB cells, therefore, in the entire campus network, most areas are covered by non-edge HNB cells. In this case, when the UE moves in the coverage area of the non-edge HNB cell, it can access the network and use the service only through the HNB cell, and no longer use the macro base station. Only setting the cell information of the authorized CSG HNB cell can prevent the UE from camping in the macro cell, because the non-edge HNB cell will not tell the UE the cell information of the macro cell through the neighbor cell list.
方法3：只设置相邻宏小区，以及具有权限的CSG HNB小区作为邻区。Method 3: Only set adjacent macro cells and authorized CSG HNB cells as adjacent cells.
如图4所示，如果HNB B与HNB A属于相同的CSG，则通过设置相邻宏小区，以及具有权限的CSG HNB小区作为邻区，在HNB A的BCCH广播信道中、以及给UE设置的测量报告中的邻区列表中，就会有HNB B的小区信息。As shown in Figure 4, if HNB B and HNB A belong to the same CSG, by setting the adjacent macro cell and the authorized CSG HNB cell as the adjacent cell, in the BCCH broadcast channel of HNB A and for the UE In the neighbor cell list in the measurement report, there will be cell information of HNB B.
对处于Idle状态的UE1，就会去测量HNB B的小区信号，由于一般情况下HNB小区的信号强度要好于宏小区的信号强度，因此UE就可能优先驻留到HNB B的小区中去，从而保证了将HNB B作为UE优先驻留的目标小区。For UE1 in the Idle state, it will measure the cell signal of HNB B. Since the signal strength of the HNB cell is generally better than that of the macro cell, the UE may preferentially camp in the cell of HNB B, thereby It is guaranteed that the HNB B is used as the target cell where the UE preferentially camps.
对处于Active状态的UE2，就会去测量HNB B的小区信号，由于一般情况下HNB小区的信号强度要好于宏小区的信号，因此UE就可能优先切换到HNB B的小区中去，从而保证了将HNB B作为UE优先切换的目标小区。For UE2 in the Active state, it will measure the cell signal of HNB B. Since the signal strength of the HNB cell is generally better than that of the macro cell, the UE may switch to the cell of HNB B preferentially, thus ensuring HNB B is used as the target cell for UE priority handover.
如果HNB B与HNB A不属于相同的CSG，则按照本方法，HNB A不会将HNB B的小区信息设置在邻区列表里，因此处于HNB A覆盖范围内的UE不会将HNB B作为邻小区。处于Idle状态的UE1，就不会去测量HNB B的小区信号，所以也不会驻留到HNB B的小区中去。从而解决了由于HNB B拒绝UE接入带来的延时增加，以及当HNB B为任何UE都有权限接入的OpenHNB时，不能给UE1提供可靠的服务质量，并有可能使UE1频繁地发起RAU/LAU等问题。If HNB B and HNB A do not belong to the same CSG, according to this method, HNB A will not set the cell information of HNB B in the neighbor cell list, so the UE within the coverage of HNB A will not use HNB B as a neighbor district. UE1 in the Idle state will not measure the cell signal of HNB B, so it will not camp in the cell of HNB B. Therefore, it solves the delay increase caused by HNB B's rejection of UE access, and when HNB B is an OpenHNB that any UE has permission to access, it cannot provide UE1 with reliable service quality, and may cause UE1 to frequently initiate RAU/LAU and other issues.
对处于Actice状态的UE2来说，在HNB A给UE2发送的测量报告中，也不会携带HNB B的小区信息，这样UE2就不会试图切换到HNB B中去，从而解决由于UE2不具有HNB B的接入权限导致的无效测量、切换失败，以及当HNB B为任何UE都有权限接入的Open HNB小区时，不能给UE2提供可靠的服务质量，并可能导致UE2掉话等问题。For UE2 in the Active state, the measurement report sent by HNB A to UE2 will not carry the cell information of HNB B, so that UE2 will not try to switch to HNB B, so as to solve the problem that UE2 does not have HNB Invalid measurement and handover failure caused by B’s access rights, and when HNB B is an Open HNB cell that any UE has access to, it cannot provide UE2 with reliable service quality, and may cause UE2 to drop calls and other problems.
方法4：设置与该HNB相邻的宏小区、具有权限的CSG HNB小区和OpenHNB小区中的一种或几种作为邻区。Method 4: Set one or more of the macro cell adjacent to the HNB, the authorized CSG HNB cell and the OpenHNB cell as the adjacent cell.
网络是否支持HNB到Open HNB的移动性，需要考虑运营商的策略，因此可以基于上述方法1、方法2和方法3，进一步将Open HNB小区的信息设置到HNB小区的邻区列表中。这样，如果HNB B是Open HNB：Whether the network supports the mobility from HNB to Open HNB needs to consider the operator's strategy. Therefore, based on the
处于Idle状态的UE1，就会去测量HNB B的小区信号，由于一般情况下HNB小区的信号强度要好于宏小区的信号，因此UE就可能优先驻留到HNBB的小区中去。UE1 in the idle state will measure the cell signal of HNB B. Since the signal strength of the HNB cell is generally better than that of the macro cell, the UE may preferentially camp in the cell of the HNB B.
处于Actice状态的UE2，就会去测量HNB B的小区信号，由于一般情况下HNB小区的信号强度要好于宏小区的信号，因此UE就可能优先切换到HNB B的小区中去。UE2 in the Active state will measure the cell signal of HNB B. Since the signal strength of the HNB cell is generally better than that of the macro cell, the UE may switch to the cell of HNB B preferentially.
其中，设置具有权限的CSG HNB小区作为邻区包括以下两种情况：Among them, setting a CSG HNB cell with authority as a neighboring cell includes the following two situations:
(1)当驻留在第一小区的所有用户都具有第二CSG HNB小区的权限时，在BCCH或者测量控制消息中的邻区列表中，设置该第二CSG HNB小区作为邻区；(1) When all users residing in the first cell have the authority of the second CSG HNB cell, set the second CSG HNB cell as the neighbor cell in the neighbor cell list in the BCCH or the measurement control message;
(2)当只有驻留在第一小区的部分用户具有第二CSG HNB小区的权限时，则只在该部分用户测量控制消息中的邻区列表中，该第二CSG HNB小区作为邻区。(2) When only some users residing in the first cell have the authority of the second CSG HNB cell, then only in the neighbor cell list in the measurement control message of this part of users, the second CSG HNB cell is used as the neighbor cell.
上述设置小区邻区列表的方法，HNB接收网络侧设备下发的HNB邻小区的小区信息，然后根据这些信息设置该HNB的邻区列表。从而确保了UE驻留到信号强度高的小区、提高了切换的成功率，保证了服务质量。In the above method of setting a neighbor list of a cell, the HNB receives the cell information of the HNB neighbor cells delivered by the network side equipment, and then sets the HNB neighbor list according to the information. Therefore, it is ensured that the UE camps in a cell with high signal strength, the success rate of handover is improved, and the service quality is guaranteed.
如图8所示，为本发明设置小区邻区列表的方法实施例二的示意图，实施例二对获取HNB邻小区的小区信息的方法进行了介绍。As shown in FIG. 8 , it is a schematic diagram of
图8(a)为通过Iu接口获取HNB邻小区的小区信息的示意图，HNB通过Iu接口从核心网CN获取该HNB邻小区的小区信息。FIG. 8( a ) is a schematic diagram of acquiring cell information of an adjacent cell of the HNB through the Iu interface. The HNB acquires cell information of the adjacent cell of the HNB from the core network CN through the Iu interface.
图8(b)为通过Iur接口获取HNB邻小区的小区信息的示意图，HNB通过Iur接口从RNC或NB+(Node B Evolution，演进节点)或HNB或eNB(evolved Node B，演进型基站)处获取该HNB小区邻小区的小区信息。Figure 8(b) is a schematic diagram of obtaining the cell information of the adjacent cell of the HNB through the Iur interface, and the HNB obtains it from the RNC or NB+ (Node B Evolution, evolved node) or HNB or eNB (evolved Node B, evolved base station) through the Iur interface Cell information of neighboring cells of the HNB cell.
图8(c)为通过Iub接口获取HNB小区邻小区的小区信息的示意图，HNB通过Iub接口从RNC或NB+或eNB处获取该HNB小区邻小区的小区信息。Figure 8(c) is a schematic diagram of obtaining the cell information of the adjacent cell of the HNB cell through the Iub interface, and the HNB obtains the cell information of the adjacent cell of the HNB cell from the RNC or NB+ or eNB through the Iub interface.
图8(d)为通过空中接口获取HNB小区邻小区的小区信息的示意图，HNB通过空中接口从RNC或HNB或NB+或eNB处获取该HNB小区邻小区的小区信息。在这种方法中，HNB需要引入一个小区搜索功能，通过执行类似于UE的小区搜索的过程，来发现并从该HNB小区邻小区的广播信道中获取该HNB小区邻小区的小区信息。该空中接口可以是3GPP(the 3rd GenerationPartner Project，第三代合作伙伴计划)的UU接口，HNB通过该UU接口在BCCH广播信道上读取RRC(Radio Resource Control，无线资源控制)系统广播消息，以获取该HNB小区邻小区的小区信息。HNB还可以采用其它非3GPP技术，例如采用Wi-Fi等技术来辅助获取该HNB小区邻小区的小区类型，即如果邻小区也是HNB并且支持Wi-Fi，那么彼此间可以通过Wi-Fi相互识别。当各HNB间不支持Iur接口时，可以采用这种方法。Fig. 8(d) is a schematic diagram of obtaining the cell information of the adjacent cell of the HNB cell through the air interface, and the HNB obtains the cell information of the adjacent cell of the HNB cell from the RNC or HNB or NB+ or eNB through the air interface. In this method, the HNB needs to introduce a cell search function to discover and obtain the cell information of the HNB cell's neighbor cell from the broadcast channel of the HNB cell's neighbor cell by performing a process similar to the UE's cell search. The air interface can be the UU interface of 3GPP (the 3rd Generation Partner Project, third generation partnership project), and the HNB reads the RRC (Radio Resource Control, radio resource control) system broadcast message on the BCCH broadcast channel through the UU interface, to Obtain the cell information of the adjacent cell of the HNB cell. HNB can also use other non-3GPP technologies, such as using Wi-Fi and other technologies to assist in obtaining the cell type of the neighboring cell of the HNB cell, that is, if the neighboring cells are also HNB and support Wi-Fi, they can recognize each other through Wi-Fi . This method can be adopted when the Iur interface is not supported between HNBs.
图8(e)为通过UE上报的测量结果获取该HNB小区邻小区的小区信息的示意图，UE测量HNB小区邻小区的小区信息，并将测量结果上报该HNB，该HNB通过该测量结果就可获取该HNB小区邻小区的小区信息。该测量结果包括从该HNB小区邻小区的BCCH信道读取到的信息，例如：该HNB小区邻小区的ID。Figure 8(e) is a schematic diagram of obtaining the cell information of the adjacent cell of the HNB cell through the measurement result reported by the UE. The UE measures the cell information of the adjacent cell of the HNB cell and reports the measurement result to the HNB. The HNB can use the measurement result Obtain the cell information of the adjacent cell of the HNB cell. The measurement result includes the information read from the BCCH channel of the adjacent cell of the HNB cell, for example: the ID of the adjacent cell of the HNB cell.
如图9所示，为本发明设置小区邻区列表的方法实施例三的流程图，更新HNB小区邻区列表的流程具体包括以下步骤：As shown in Figure 9, it is a flow chart of the third embodiment of the method for setting the neighbor list of the cell in the present invention, and the process of updating the neighbor list of the HNB cell specifically includes the following steps:
步骤S901，检测与第一HNB相邻的第二HNB是否关机或开机。由于HNB是用户自己管理的设备，有可能随时开机或关机。本发明实施例以HNB关机为例进行说明。如图4所示，如果原来HNB A邻区列表中具有HNB B的小区信息，则在HNB B关机后，HNB A小区邻区列表中的HNB B小区的小区信息应该被删除，否则将会引起UE无效测量、掉话等问题。其中，检测HNB是否关机的方法有以下两种：Step S901, detecting whether a second HNB adjacent to the first HNB is powered off or powered on. Since HNB is a device managed by the user itself, it may be turned on or off at any time. The embodiment of the present invention is described by taking the shutdown of the HNB as an example. As shown in Figure 4, if there is cell information of HNB B in the original neighbor list of HNB A, after HNB B shuts down, the cell information of HNB B cell in the neighbor list of HNB A cell should be deleted, otherwise it will cause Problems such as UE invalid measurement and call drop. Among them, there are two methods for detecting whether the HNB is powered off:
方法1：定期活跃性检测Method 1: Periodic activity detection
如图10所示，网络侧设备周期性地发送激活测试消息给HNB，HNB在接收到该激活测试消息之后，如果给与回应，则表示该HNB还是开机状态；如果HNB不回应该激活测试消息的次数超过CN设置的次数，则CN认为该HNB已经关机了。As shown in Figure 10, the network side equipment periodically sends an activation test message to the HNB. After the HNB receives the activation test message, if it responds, it means that the HNB is still in the power-on state; if the HNB does not respond to the activation test message If the number of times exceeds the number of times set by the CN, the CN considers that the HNB has been shut down.
方法2：底层协议支持的心跳检测方法。例如：通过SCCP(SignallingControl Connection Part，信令连接部分)，SCTP(Simple Control TransmissionProtocol，简单控制传输协议)协议本身支持的心跳检测机制，来检测HNB是否关机。Method 2: The heartbeat detection method supported by the underlying protocol. For example: through SCCP (Signalling Control Connection Part, signaling connection part), SCTP (Simple Control Transmission Protocol, simple control transmission protocol) heartbeat detection mechanism supported by the protocol itself, to detect whether the HNB is powered off.
步骤S902，更新第一HNB小区的邻区列表。在检测到第二HNB关机之后，CN将向与第二HNB相邻的第一HNB发送邻区信息更新消息，用于通知第一HNB，第二HNB关机了，处于不可用状态。第一HNB在接收到该邻区信息更新消息之后，将已关机的第二HNB从第一HNB小区的邻区列表中删除，并向CN发送邻区信息更新响应消息以响应邻区信息更新消息，如图11所示。邻区信息更新消息和邻区信息更新响应消息可以由其他消息携带。Step S902, updating the neighbor cell list of the first HNB cell. After detecting that the second HNB is powered off, the CN will send a neighboring cell information update message to the first HNB adjacent to the second HNB to notify the first HNB that the second HNB is powered off and is in an unavailable state. After receiving the neighbor cell information update message, the first HNB deletes the powered off second HNB from the neighbor cell list of the first HNB cell, and sends a neighbor cell information update response message to the CN in response to the neighbor cell information update message , as shown in Figure 11. The neighbor cell information update message and the neighbor cell information update response message may be carried by other messages.
在实施例一中，HNB小区邻小区的小区信息是网络侧设备下发给该HNB的，但是邻区列表的最终配置是由HNB自己决定的。在本发明实施例四中，实施例一的两个步骤都由网络侧设备执行。即网络侧设备根据一个小区的信息，以及与该小区相邻的小区的信息，选择合适的邻小区，直接设置每个HNB小区的邻区列表，其设置方法可以采用实施例一步骤S602中的四种方法，然后将设置好的邻区列表下发给每个HNB。In the first embodiment, the cell information of the neighboring cells of the HNB cell is delivered to the HNB by the network side equipment, but the final configuration of the neighboring cell list is determined by the HNB itself. In Embodiment 4 of the present invention, both steps in
