一种邻区检测方法、系统及一种基站Neighbor cell detection method, system and base station

技术领域technical field

本发明涉及移动通信领域，特别涉及一种在通用移动通信系统(UMTS，Universal MobileTelecommunication System)中邻区检测方法、系统及一种基站。The present invention relates to the field of mobile communications, in particular to a method and system for detecting neighboring cells in a Universal Mobile Telecommunications System (UMTS, Universal Mobile Telecommunications System) and a base station.

背景技术Background technique

近年来移动通信飞速发展，网络规模不断扩大，用户数量急速上升，用户对网络性能质量的要求也不断提高，运营商对网络的管理也从对信号覆盖的定性要求转变为对网络性能指标的定量管理。In recent years, with the rapid development of mobile communication, the scale of the network has continued to expand, the number of users has increased rapidly, and the requirements of users for network performance and quality have also continued to increase. Operators' management of the network has also changed from qualitative requirements for signal coverage to quantitative network performance indicators. manage.

在移动通信网络的建设中，网络规划占据了很重要的位置，良好的网络规化能够大幅度地提升移动通信网络的性能。In the construction of mobile communication networks, network planning occupies a very important position, and good network planning can greatly improve the performance of mobile communication networks.

在现有技术中，工作人员在建网时通过网络规划仿真工具对基站布局和无线资源进行初步规划，并对参数进行初步配置。工作人员利用仿真规划软件对系统的无线环境进行仿真模拟，以便于在整体上对系统进行分析，包括对初定站址的覆盖范围预测、对周围基站话务分担的合理性分析等。在完成初步建设后，工作人员会不断对网络进行优化，使得建设的网络达到比较好的效果。In the prior art, when building a network, staff use a network planning simulation tool to initially plan base station layout and wireless resources, and perform initial configuration of parameters. The staff uses the simulation planning software to simulate the wireless environment of the system, so as to analyze the system as a whole, including the coverage prediction of the initial station site, the rational analysis of the traffic sharing of the surrounding base stations, etc. After the initial construction is completed, the staff will continue to optimize the network so that the constructed network can achieve better results.

随着大量的家用基站(HNB，Home NodeB)密集部署，将对网络规划与优化带来很大的挑战。在网络规划与优化过程中，需要配置HNB的邻区列表。以UMTS为例，按照现有技术的邻区配置方法，一个无线网络控制器(RNC，Radio Network Controller)内的小区的邻区列表，是RNC配置给NodeB的，跨RNC的邻区列表信息是网管配置给RNC的。这些配置的方法为手工配置。With the dense deployment of a large number of home base stations (HNB, Home NodeB), it will bring great challenges to network planning and optimization. In the process of network planning and optimization, it is necessary to configure the neighbor cell list of the HNB. Taking UMTS as an example, according to the neighbor cell configuration method in the prior art, the neighbor list of a cell in a radio network controller (RNC, Radio Network Controller) is configured by the RNC to the NodeB, and the cross-RNC neighbor list information is Configured by the network management to the RNC. These configuration methods are manual configuration.

按照这种方法，获取与一个HNB相邻的其它HNB的邻区列表的配置将是比较复杂的，因为：According to this method, it will be more complicated to obtain the configuration of neighbor lists of other HNBs adjacent to one HNB, because:

1)HNB数量巨大，导致HNB之间的邻区关系数量更加巨大。为如此众多的HNB配置如此复杂的邻区列表是一个巨大的工作，对运营商是一个挑战。1) The large number of HNBs leads to a larger number of neighbor relationships between HNBs. Configuring such a complex neighbor list for so many HNBs is a huge work and a challenge for operators.

2)HNB是用户设备，它的位置可能被用户随时移动，甚至搬到不同的住所，也可能随时被用户开关机。HNB的位置变化或每次开关机都会带来邻区关系的变化，需要动态地更新这种邻区关系。按照现有的配置方法不可能适应这种要求。2) HNB is user equipment, its location may be moved by the user at any time, even moved to a different residence, and may also be turned on and off by the user at any time. Changes in the location of the HNB or each switch on and off will bring changes in the relationship between neighboring cells, which needs to be dynamically updated. It is impossible to meet this requirement according to the existing configuration method.

3)HNB是用户设备，如果让用户去配置这些专业的邻区关系不现实。3) HNB is user equipment, it is unrealistic for users to configure these specialized neighbor relationships.

4)HNB之间的邻区关系与它们彼此的信号能否覆盖有关系，这个关系是运营商无法获知的。因此也不能准确地配置它们的邻区关系。4) The relationship between adjacent cells between HNBs is related to whether their signals can cover each other, and this relationship cannot be known by operators. Therefore, their neighbor relationship cannot be accurately configured.

具体实施方式Detailed ways

为使本发明的目的、技术方案和优点更加清楚，下面将结合附图对本发明实施方式作进一步地详细描述。In order to make the object, technical solution and advantages of the present invention clearer, the implementation manner of the present invention will be further described in detail below in conjunction with the accompanying drawings.

实施例1Example 1

本发明实施例提供了一种HNB邻区检测方法，在HNB之间实现一种信息检测机制，HNB的邻区将自动被HNB检测并保存。The embodiment of the present invention provides a method for detecting adjacent cells of HNBs. An information detection mechanism is implemented between HNBs, and the adjacent cells of HNBs will be automatically detected and saved by the HNBs.

如图1所示，在宏小区(Macro Cell)的覆盖范围内，部署了4个HNB A，B，C，D基站。这四个基站的信号覆盖范围分别称为HNB A，B，C，D小区。实际情况中宏小区的覆盖范围要比HNB的覆盖范围大得多，图中的圆圈没有比例关系。As shown in Figure 1, four HNB A, B, C, and D base stations are deployed within the coverage of the Macro Cell. The signal coverage areas of these four base stations are called HNB A, B, C, and D cells respectively. In actual situations, the coverage of the macro cell is much larger than that of the HNB, and the circles in the figure are not proportional.

下面结合附图1，以HNB A作为检测基站为例，说明HNB A如何检测邻区。如图3所示，具体步骤如下：In the following, with reference to Figure 1, taking HNB A as the detection base station as an example, how HNB A detects neighboring cells is explained. As shown in Figure 3, the specific steps are as follows:

步骤101：HNB A检测周围基站发送的信号。Step 101: HNB A detects signals sent by surrounding base stations.

HNB A进行小区搜索，检测周围小区的信号，其中优选的方法是周期性地进行搜索。具体的检测方法可以采用如下方式：HNB A conducts cell search and detects the signals of surrounding cells, and the preferred method is to search periodically. Specific detection methods can be used in the following ways:

a)HNB A暂停发送下行数据，切换到接收数据状态。a) HNB A suspends sending downlink data and switches to the state of receiving data.

b)时隙同步b) Slot synchronization

一个无线帧为10ms，38400码片，又分为15个时隙。由于物理信道之间是同步的。首先要获取各时隙的边界，从而与各物理信道实现时隙同步。这一步是通过捕获主同步信道来实现的。A wireless frame is 10ms, 38400 chips, and is divided into 15 time slots. Because the physical channels are synchronized. Firstly, the boundary of each time slot must be obtained, so as to realize time slot synchronization with each physical channel. This step is achieved by capturing the master sync channel.

主同步信道不属于码信道，没有经过扩频和加扰处理。主同步信道在每个时隙的起始处重复发送主同步码，为256码片，占整个时隙的1/10。所有小区的主同步码相同，而且HNB预先知道其码片序列，因此只需要用一个性能较好的匹配滤波器就可以检测、捕获到该主同步码，从而确定各物理信道的时隙边界。The primary synchronization channel does not belong to the code channel, and has not been processed by spreading and scrambling. The primary synchronization channel repeatedly sends the primary synchronization code at the beginning of each time slot, which is 256 chips, accounting for 1/10 of the entire time slot. The primary synchronization code of all cells is the same, and the HNB knows its chip sequence in advance, so only a matched filter with better performance can be used to detect and capture the primary synchronization code, so as to determine the time slot boundary of each physical channel.

c)帧同步c) Frame synchronization

这一步是通过捕获从同步信道来实现的。从同步信道也不属于码信道，没有经过扩频和加扰处理。从同步信道上发送从同步码，从同步码也是256个码片，在每个时隙的开始处与主同步码一起发送，每个时隙使用一个从同步码。所不同的是，从同步码总共有16个不同的码片序列，这些从同步码又被编排成64个不同的组合，每个组合为15个从同步码字长，用于一个无线帧，需要注意的是，在某一组合中同一从同步码可能出现若干次，而每个组合对应于一组主扰码。This step is achieved by capturing the slave sync channel. The secondary synchronization channel does not belong to the code channel either, and has not been processed by spreading and scrambling. The slave synchronization code is sent from the synchronization channel, and the slave synchronization code is also 256 chips. It is sent together with the master synchronization code at the beginning of each time slot, and each time slot uses a slave synchronization code. The difference is that there are a total of 16 different chip sequences in the secondary synchronization code, and these secondary synchronization codes are programmed into 64 different combinations, each combination is 15 secondary synchronization codewords long, and is used in one wireless frame. It should be noted that the same secondary synchronization code may appear several times in a certain combination, and each combination corresponds to a group of primary scrambling codes.

下行扰码是由长度为18位的移位寄存器生成的PN序列，因此总共有218-1个，常用的有8192个，又分为主扰码和从扰码，其中主扰码有512个，分为64组，每组8个。因此，在实现物理信道的帧同步的同时，终端可以获悉该小区的无线帧中使用的从同步码字组合，从而可以确定该小区使用的主扰码所属的组别。The downlink scrambling code is a PN sequence generated by a shift register with a length of 18 bits, so there are 218-1 in total, and 8192 are commonly used, which are divided into main scrambling codes and slave scrambling codes, of which there are 512 main scrambling codes , divided into 64 groups, 8 in each group. Therefore, while realizing the frame synchronization of the physical channel, the terminal can learn the combination of the secondary synchronization code words used in the radio frame of the cell, so as to determine the group to which the primary scrambling code used by the cell belongs.

d)捕获主扰码d) capture the main scrambling code

有了步骤b、c的基础，并且知道主公共导频信道的信道化码为C c h 2560，HNB即能够同步到主公共导频信道的无线帧。With the basis of steps b and c, and knowing that the channelization code of the main common pilot channel is C ch 2560, the HNB can synchronize to the radio frame of the main common pilot channel.

主公共导频信道是一个码信道，在整个小区内广播，每个小区有且仅有一个主公共导频信道。该信道在发射前需要经过扩频和加扰。在扩频前，该信道发送4个符号“1”，即“1111”。经过扩频，该信道发送256个符号“1”。再用一个主扰码进行加扰，最后在该信道的每一帧上发射的就是38400码片的主扰码。The main common pilot channel is a code channel, which is broadcast in the whole cell, and each cell has and only one main common pilot channel. The channel needs to be spread and scrambled before transmission. Before spreading, the channel sends 4 symbols "1", that is, "1111". After spreading, the channel transmits 256 symbols of "1". A main scrambling code is used for scrambling, and finally the main scrambling code of 38400 chips is transmitted on each frame of the channel.

由于已经确定该主扰码所属的组号，因此，只需要定位到该主扰码组，然后从8个主扰码中找到与本小区匹配的主扰码，捕获主扰码的工作即告结束。Since the group number to which the primary scrambling code belongs has been determined, it is only necessary to locate the primary scrambling code group, and then find the primary scrambling code that matches this cell from the 8 primary scrambling codes, and the work of capturing the primary scrambling code will be completed Finish.

然后，就可以用主扰码解码主公共控制物理信道，从而解调出小区的广播消息。Then, the primary common control physical channel can be decoded with the primary scrambling code, so as to demodulate the broadcast message of the cell.

最后，基站实现了对周围小区信号的检测。Finally, the base station realizes the detection of surrounding cell signals.

步骤102：HNB A把检测到的信号对应的小区列为自己的邻区。Step 102: HNB A lists the cell corresponding to the detected signal as its neighbor cell.

在实际操作过程中，由于在HNB大量密集部署时，HNB A可能检测到多个邻区，而按照现有技术邻区列表，可以容纳的邻区数量一般是32个，因此，HNB也可以按照信号强度，只选择某些信号比较强的HNB作为自己的邻区。In the actual operation process, since HNB A may detect multiple neighboring cells when a large number of HNBs are densely deployed, and according to the prior art neighboring cell list, the number of neighboring cells that can be accommodated is generally 32, therefore, HNB can also be based on Signal strength, only select certain HNBs with relatively strong signals as their neighbors.

采用本发明实施例所述的技术方案，通过搜索周围小区的信号获取邻区的信息，实现了自动检测，也无需用户或运营商参与配置。By adopting the technical solution described in the embodiment of the present invention, the information of neighboring cells is obtained by searching signals of surrounding cells, and automatic detection is realized, and no user or operator participates in configuration.

实施例2Example 2

以图1所示的工作场景为例，根据实施例1中的技术方案，HNB A首先可以检测到来自宏小区的信号，所以HNB A将宏小区作为邻区。对于其它HNB对应的小区，虽然HNB B信号覆盖区域与HNB A信号覆盖的区域有部分重叠，但是HNB B的信号不能到达HNB A的位置，因而HNB A无法将HNB B作为邻区；同理，虽然HNB C与HNB A是相切关系，但是HNB C的信号不能到达HNBA的位置，HNB A也无法将HNB C作为邻区；而HNB D的信号能够到达HNB A的位置，因此，HNB A将HNB D作为邻区。Taking the working scenario shown in Figure 1 as an example, according to the technical solution in Embodiment 1, HNB A can first detect the signal from the macro cell, so HNB A regards the macro cell as a neighboring cell. For the cells corresponding to other HNBs, although the HNB B signal coverage area partially overlaps with the HNB A signal coverage area, the HNB B signal cannot reach the location of HNB A, so HNB A cannot use HNB B as a neighboring cell; similarly, Although HNB C is tangent to HNB A, the signal of HNB C cannot reach the location of HNB A, and HNB A cannot use HNB C as a neighboring cell; while the signal of HNB D can reach the location of HNB A, therefore, HNB A will HNB D acts as a neighboring cell.

由此可见，对于HNB A而言，从网络部署的角度看，宏小区，HNB B，C，D是它的邻区。而从实际检测过程来看，HNB A可以检测到的邻区为：宏小区和HNB D，并把它们列成是邻区；HNB B、C虽然物理上与HNB A是邻区，但是由于HNB A无法检测到它的信号，无法将其设为邻区。即HNB只能检测到与之距离比较近，信号能覆盖到HNB部署位置的其它小区。It can be seen that, for HNB A, from the perspective of network deployment, the macro cell, HNB B, C, and D are its neighbors. From the perspective of the actual detection process, the neighboring cells that HNB A can detect are: the macro cell and HNB D, and list them as neighboring cells; although HNB B and C are physically neighboring cells to HNB A, because HNB A cannot detect its signal and cannot make it a neighbor. That is, the HNB can only detect other cells that are relatively close to it and whose signals can cover the location where the HNB is deployed.

因此，为了使物理上实际是邻区的HNB被HNB A检测到，需要进一步优化，在本实施例中，HNB可以周期性地提高发射功率，增大自己的覆盖范围，以便周围的HNB可以检测到它的存在。Therefore, in order to make the HNB that is actually a neighboring cell physically detected by HNB A, further optimization is required. In this embodiment, HNB can periodically increase the transmission power to increase its own coverage, so that surrounding HNBs can detect to its existence.

具体方法是：设定一个时间值T，HNB每间隔T，增大公共导频信道、同步信道、广播信道至少之一的功率，并持续一段时间D。The specific method is: set a time value T, and the HNB increases the power of at least one of the common pilot channel, synchronization channel, and broadcast channel every interval T, and lasts for a period of time D.

对于提高发射功率具体有以下几种方案：There are several options for increasing the transmit power:

1)HNB提高自己的发射功率为HNB允许的最大发射功率；1) HNB increases its transmission power to the maximum transmission power allowed by HNB;

HNB提高发射功率时，采用最大发射功率，这样信号所及范围将是它的覆盖范围，表示HNB有能力覆盖这些地方。如果被其它HNB检测到，将把它列为邻区。When HNB increases the transmission power, it adopts the maximum transmission power, so that the range of the signal will be its coverage area, which means that HNB has the ability to cover these places. If it is detected by other HNB, it will be listed as a neighboring cell.

2)HNB提高自己的发射功率，使得其覆盖半径为正常运行时的2倍；2) HNB increases its transmission power so that its coverage radius is twice that of normal operation;

对于在正常情况下，所有HNB覆盖半径是一致的系统，可以采取这种方法。如图2所示，假设其覆盖半径是R。对于HNB C来说，HNB A和HNB B都是它的邻区，HNB C与它们的位置关系接近于相切，可以认为是代表了一种邻区的极限场景。For a system where all HNB coverage radii are consistent under normal conditions, this method can be adopted. As shown in Figure 2, assume that its coverage radius is R. For HNB C, both HNB A and HNB B are its neighbors, and the position relationship between HNB C and them is close to tangent, which can be considered as representing a limit scenario of a neighbor.

此时，为了让HNB C与HNB A、HNB B之间能够检测到，需要这些HNB提高发射功率，使它们的覆盖半径扩大成正常覆盖半径的2倍，即2R。这样，HNB C与HNB A、HNB刚好可以检测到。At this time, in order to enable detection between HNB C, HNB A, and HNB B, these HNBs need to increase their transmission power to expand their coverage radius to twice the normal coverage radius, that is, 2R. Like this, HNB C and HNB A, HNB just can be detected.

如果HNB提高覆盖半径为正常覆盖半径的2倍后，仍然不能被其它HNB检测到，则一定不是邻区。If the HNB increases the coverage radius to twice the normal coverage radius and still cannot be detected by other HNBs, it must not be a neighboring cell.

3)提高HNB的发射功率到某个值。这个值可以是设定的，或者是动态的用某个算法计算出来的。3) Increase the transmit power of the HNB to a certain value. This value can be set, or dynamically calculated by an algorithm.

采用本发明实施例所述的技术方案，通过HNB提高发射功率，增大自己的覆盖范围，可以保证HNB能够检测到网络部署的邻小区。By adopting the technical solution described in the embodiment of the present invention, the HNB increases the transmission power and increases its own coverage, which can ensure that the HNB can detect the adjacent cells deployed by the network.

实施例3Example 3

在某些情况下，由于两个基站(HNB与宏小区，HNB与HNB)的覆盖范围不对等。比如：一个HNB或者NodeB的覆盖范围大，一个覆盖范围小。一个HNB或者NodeB的覆盖范围可以覆盖其它HNB；但其它HNB即使增大功率，增加覆盖范围后，仍然无法覆盖该HNB或者NodeB。这样，会产生覆盖范围小的基站能够收到覆盖范围大的基站的信号，但覆盖范围大的基站不能够收到覆盖范围小的基站的信号。In some cases, because the coverages of two base stations (HNB and macro cell, HNB and HNB) are not equal. For example: one HNB or NodeB has a large coverage area, and the other has a small coverage area. The coverage of one HNB or NodeB can cover other HNBs; however, even if other HNBs increase their power and coverage, they still cannot cover this HNB or NodeB. In this way, a base station with a small coverage area can receive signals from a base station with a large coverage area, but a base station with a large coverage area cannot receive signals from a base station with a small coverage area.

此时，为了让覆盖范围较大的基站也能获知覆盖范围小的基站是自己的邻区，如果仅仅依赖于覆盖范围较大的基站检测信号是不行的。所以，需要基站检测到一个邻区之后，与之建立通信，把这种邻区关系通知对方。分以下两种情况：At this time, in order for the base station with a larger coverage area to know that the base station with a smaller coverage area is its neighbor cell, it is not enough to only rely on the detection signal of the base station with a larger coverage area. Therefore, after the base station detects a neighboring cell, it needs to establish communication with it, and notify the other party of the neighboring cell relationship. There are two situations:

a.HNB检测到宏小区是它的邻区后，可以与宏小区建立通信，告知对方互为邻区。具体需要考虑两种情况，如果HNB与宏小区之间具有接口，则通过该接口告诉宏小区；如果它们之间没有接口，则需要先告知网络侧，通过网络侧告知宏小区。a. After the HNB detects that the macro cell is its neighbor cell, it can establish communication with the macro cell and inform the other party that they are neighbor cells. Specifically, two situations need to be considered. If there is an interface between the HNB and the macro cell, the macro cell will be notified through the interface; if there is no interface between them, the network side will first be notified, and the macro cell will be notified through the network side.

b.HNB检测到一个HNB邻区后，与之建立通信，告知对方互为邻区。建立通信的方法类似上述情况a，通过HNB与其它HNB或者RNC之间的接口，或者通过核心网，即网络侧告知；或者利用获取的对方的IP地址，通过IP链接与其通信，生成相应的邻区信息。其中，对方的IP地址根据对方HNB广播的自己小区的标识和通信地址，如HNB的Cell ID，HNB IP地址得到。b. After the HNB detects a neighboring cell of the HNB, it establishes communication with it and informs the other side that they are neighboring cells. The method of establishing communication is similar to the above case a, through the interface between the HNB and other HNBs or RNCs, or through the core network, that is, notification from the network side; or use the acquired IP address of the other party to communicate with it through an IP link to generate a corresponding neighbor district information. Wherein, the IP address of the other party is obtained according to the identity and communication address of the own cell broadcast by the other party's HNB, such as the Cell ID of the HNB and the HNB IP address.

采用本发明实施例所述的技术方案，基站在检测到一个邻区之后，与之建立通信，把这种邻区关系通知对方，可以解决由于邻小区的覆盖范围小而导致周围小区无法获取该邻小区的信号的问题，使邻区列表内容完整By adopting the technical solution described in the embodiment of the present invention, after the base station detects a neighboring cell, it establishes communication with it, and notifies the other party of the neighboring cell relationship, which can solve the problem that the surrounding cells cannot obtain the neighboring cell due to the small coverage of the neighboring cell. The problem of the signal of the neighboring cell, so that the content of the neighboring cell list is complete

实施例4Example 4

由于HNB接收到的信号可能是来自HNB的，也可能是来自宏小区的。而HNB需要能判断出两个类型邻区的类型。例如一个正在发生业务的UE离开HNB时，需要发生切换，如果切换到宏小区更能可靠地保证其业务，那么HNB做出切换判决时，就需要知道哪个小区是宏小区。The signal received by the HNB may be from the HNB or from the macro cell. The HNB needs to be able to determine the types of the two types of neighboring cells. For example, when a service-providing UE leaves the HNB, handover needs to occur. If handover to a macro cell can ensure its services more reliably, then when the HNB makes a handover decision, it needs to know which cell is the macro cell.

本实施例采取的方法是：HNB根据来自其它相邻的HNB或者宏小区的信号的差异性，即不同的类别，来知道它们的类型。例如：The method adopted in this embodiment is: the HNB knows the types of signals from other neighboring HNBs or macro cells according to their differences, that is, different types. For example:

如果发射信号的小区是HNB小区，在小区广播消息中会携带一个小区类型标识，指示这个小区的类型是HNB；If the cell transmitting the signal is an HNB cell, a cell type identifier will be carried in the cell broadcast message, indicating that the cell type is HNB;

如果发射信号的小区是宏小区，在小区广播消息中会携带一个小区类型标识，指示这个小区的类型是宏小区；If the cell transmitting the signal is a macro cell, a cell type identifier will be carried in the cell broadcast message, indicating that the cell type is a macro cell;

HNB根据接收到的这个指示信息，判断对方的类型。The HNB judges the type of the other party according to the received indication information.

本发明实施例通过在基站发射的信息中增加该基站类型，使收到信号的小区可以区分该邻区的小区类型。In the embodiment of the present invention, by adding the base station type to the information transmitted by the base station, the cell receiving the signal can distinguish the cell type of the neighboring cell.

实施例5Example 5

如果发出信号的小区是HNB小区，那么小区广播消息中会进一步标识它是闭合用户组还是开放用户组；对于闭合用户组可以进一步携带闭合用户组组号。CSG(Closed SubscriberGroup，封闭式用户组)HNB表示该HNB只能给某些UE提供服务，Open HNB(开放式用户组)表示该HNB可以给任何UE提供服务。If the cell sending the signal is an HNB cell, the cell broadcast message will further identify whether it is a closed subscriber group or an open subscriber group; the closed subscriber group may further carry a closed subscriber group number. CSG (Closed Subscriber Group, Closed Subscriber Group) HNB indicates that the HNB can only provide services to certain UEs, and Open HNB (Open Subscriber Group) indicates that the HNB can provide services to any UE.

为了使HNB能够判断相邻HNB是CSG HNB还是Open HNB，以便进行切换，可以采取以下步骤：In order to enable the HNB to determine whether the adjacent HNB is a CSG HNB or an Open HNB for handover, the following steps can be taken:

在HNB发射的信息中携带一个HNB类型，对于CSG HNB的类型，还需要进一步携带一个授权列表，表明给哪些UE提供服务。An HNB type is carried in the information transmitted by the HNB. For the CSG HNB type, an authorization list needs to be further carried to indicate which UEs are provided with services.

接收到发射信息的HNB将该小区作为邻区，并获取信息中的HNB类型，如果是Open HNB，则在切换时源HNB可以把这个相邻HNB列为测量小区，即UE是可以切换到这个HNB中去的。如果HNB知道相邻HNB是CSG HNB，则进一步判断UE是否具有这个相邻CSG HNB的接入权限，如果有接入权限，则可以把这个小区列为测量小区，否则不列为测量小区。The HNB that receives the transmission information regards the cell as a neighboring cell, and obtains the HNB type in the information. If it is an Open HNB, the source HNB can list this neighboring HNB as a measurement cell during handover, that is, the UE can switch to this cell. Went in HNB. If the HNB knows that the adjacent HNB is a CSG HNB, it further judges whether the UE has the access authority of the adjacent CSG HNB. If it has the access authority, this cell can be listed as a measurement cell, otherwise it is not listed as a measurement cell.

HNB可以进一步依据检测到的HNB的广播信道中的HNB小区的组号，判断邻闭合用户组HNB小区是否与HNB是一个闭合用户组。The HNB may further judge whether the adjacent closed subscriber group HNB cell and the HNB are a closed subscriber group according to the detected group number of the HNB cell in the broadcast channel of the HNB.

本发明实施例通过在基站发射的信息中增加HNB的小区类型，使收到信号的小区可以区分其类型。In the embodiment of the present invention, the cell type of the HNB is added to the information transmitted by the base station, so that the cell receiving the signal can distinguish its type.
