本发明属于移动通信领域,尤其涉及一种第三代移动通信室内家用基站自主配置工作频率的方法。The invention belongs to the field of mobile communication, and in particular relates to a method for autonomously configuring a working frequency of a third-generation mobile communication indoor home base station.
背景技术Background technique
发展和逐步推广中的第三代移动通信相对于第二代移动通信系统,具有工作频率高、穿透能力弱,空间损耗大、70%的业务发生在室内、用户需要高速和宽带的业务等特点。室内家用基站就是满足这种要求的解决方法。Compared with the second-generation mobile communication system, the third-generation mobile communication that is being developed and gradually promoted has high operating frequency, weak penetrating ability, large space loss, 70% of the business occurs indoors, and users need high-speed and broadband services, etc. features. The indoor femto base station is the solution to meet this requirement.
室内家用基站特点在于:支持第三代移动通信系统的Uu空中接口、有线端口是通过室内已有的宽带网络接入到第三代移动通信系统的核心网、提供高速业务、室内家用。此种结构解决了室内环境的限制,移动用户能够在室内独享资源,获得移动宽带多媒体业务。由于室内家用基站是针对家庭用户应用的设备,属于自主应用设备,使用数量很多,可以安装在室内的任何位置。但实际使用时的情况是:在需要安装室内家用基站的周边区域,已经安装有其它第三代移动通信基站和室内家用基站,如何合理地选择位置安装待接入的室内家用基站、合理地规划频率、选择合适的工作频点、与周围已开启的设备能良好共存、彼此间干扰最小、业务质量满足要求等问题,是需要引起设备提供商重视和解决的。The characteristics of the indoor home base station are: the Uu air interface and wired port supporting the third generation mobile communication system are connected to the core network of the third generation mobile communication system through the existing indoor broadband network, providing high-speed services, and indoor home use. This structure solves the limitation of the indoor environment, and mobile users can exclusively enjoy resources indoors and obtain mobile broadband multimedia services. Since the indoor femto base station is a device for home users, it is an independent application device, and it is widely used, and it can be installed anywhere indoors. But the situation in actual use is: in the surrounding area where indoor femto base stations need to be installed, other third-generation mobile communication base stations and indoor femto base stations have been installed. Frequency, selection of a suitable working frequency point, good coexistence with surrounding enabled devices, minimal interference between each other, and quality of service that meet the requirements, etc., need to be paid attention to and solved by equipment providers.
图1给出的是典型的第三代移动通信基站和室内家用基站的应用图。Figure 1 shows the application diagram of typical third-generation mobile communication base stations and indoor home base stations.
基站NB是已经开启的第三代移动通信基站,NB通过Iub接口连接到无线网络控制器RNC,再通过Iu接口和核心网CN相连。HNB是已开启的室内家用基站,HNB-new是准备安装的室内家用基站,它们通过室内有线宽带媒介连接到接入控制器APC,再通过Iu接口和核心网CN相连。The base station NB is a third-generation mobile communication base station that has been turned on. The NB is connected to the radio network controller RNC through the Iub interface, and then connected to the core network CN through the Iu interface. HNB is the indoor home base station that has been turned on, and HNB-new is the indoor home base station to be installed. They are connected to the access controller APC through the indoor wired broadband medium, and then connected to the core network CN through the Iu interface.
目前第三代移动通信系统对基站NB工作频率的配置是通过网络规划进行统一配置的。按规划方案进行的基站NB频点配置可保证整个系统的频率分配合理、NB之间的相互干扰最小。第三代移动通信系统中的基站NB在进行基站工作频点配置之前,运营商会根据实际的基站站点分布情况,制定统一的频率规划方案,根据方案配置所有基站设备的工作频率。而室内家用基站的特点是以居家为基本单位、数量众多、分布密集、自主安装、即插即用,如果和室外基站NB一样或一起进行频率规划,这种规划会由于新的HNB设备的不断接入变得非常频繁、困难和复杂。At present, the third-generation mobile communication system configures the operating frequency of the base station NB through network planning. The base station NB frequency configuration according to the planning scheme can ensure the reasonable frequency allocation of the whole system and the minimum mutual interference between NBs. Before the base station NB in the third-generation mobile communication system configures the operating frequency of the base station, the operator will formulate a unified frequency planning plan according to the actual distribution of base station sites, and configure the operating frequencies of all base station equipment according to the plan. The indoor home base station is characterized by the home as the basic unit, a large number, dense distribution, independent installation, and plug-and-play. If the frequency planning is carried out the same as or together with the outdoor base station NB, this planning will be due to the continuous development of new HNB equipment. Access becomes very frequent, difficult and complex.
因此,研究和开发出适用于室内家用基站HNB能够自主进行室内家用基站HNB工作频率配置的方法,无疑会对整个系统的普及、快速推广应用会带来很大的好处。Therefore, researching and developing a method suitable for the indoor home base station HNB to independently configure the operating frequency of the indoor home base station HNB will undoubtedly bring great benefits to the popularization and rapid application of the entire system.

Analyze the spectrum characteristics and select all available frequency bands. According to the maximum number of carriers supported by HNB-new, determine the occupied bandwidth of HNB-new, select the frequency band that matches the occupied bandwidth of HNB-new in the available frequency band area, and determine the main carrier and auxiliary carrier in the selected frequency band working frequency. Adopting this autonomous frequency point configuration method can guarantee the performance requirements when the HNB-new coexists with the existing HNB or NB.

The receiving reference level can be a receiving reference sensitivity level or a user-defined receiving signal level. HNB-new searches for surrounding NBs and HNBs in all the third-generation mobile communication working frequency bands it supports, and obtains the broadcast messages corresponding to each NB and HNB, including identification codes, primary frequency points and secondary frequency point information. According to the identification code and frequency point information, the distribution of NB and HNB in the frequency domain can be obtained. In Fig. 3, Fig. 4 and Fig. 5, 101-105 are HNBs found around HNB-new; 201-204 are NBs found around HNB-new; the interference threshold control level is 401.
(3)选择最佳安装位置。(3) Choose the best installation location.
对在位置A、位置B和位置C处接收到的周边HNB和NB的信号进行分析和比较。统计在各预安装位置上超出干扰门限的信号个数和电平大小。The signals of surrounding HNBs and NBs received at Location A, Location B and Location C are analyzed and compared. Count the number and level of signals exceeding the interference threshold at each pre-installation position.
如果在各位置上接收到的所有信号均在干扰门限以下,则表明所选择的安装位置A、B、C均可接入HNB-new。如图4,为周边HNB的信号101~105和NB的信号201~204均在干扰门限401以下的情况。此时选择HNB信号电平都较低和NB信号接收质量较好的位置作为安装位置。If all signals received at each location are below the interference threshold, it indicates that the selected installation locations A, B, and C can all be connected to HNB-new. As shown in FIG. 4 , it is a situation where the signals 101 - 105 of the surrounding HNB and the signals 201 - 204 of the NB are all below the
如果图4对应的位置不存在,则寻找HNB和NB的信号超出干扰门限401最少的位置作为安装位置。以图3和图5为例,图3是HNB和NB的信号超出干扰门限401较多的安装位置,此位置对设备工作以及可用频带选择不理想。图5是HNB和NB的信号超出干扰门限401最少的安装位置。比较各位置的数据结果,即选择图5对应的位置作为最佳安装位置。如果各安装位置超出干扰门限401的个数相等的话,选择HNB信号电平都较低和NB信号接收质量较好的位置作为安装位置。If the location corresponding to FIG. 4 does not exist, then find the location where the signals of the HNB and NB exceed the
(4)在最佳安装位置接收信号,分析HNB和NB的信号分布情况,找出HNB-new作为同步信号提取的同步源NB、HNB-new可用的频带和工作频点。(4) Receive the signal at the best installation position, analyze the signal distribution of HNB and NB, and find out the available frequency band and operating frequency point of the synchronization source NB and HNB-new extracted by HNB-new as the synchronization signal.
根据对最佳位置接收到的信号的分析,如图5,选择信号质量较好的基站NB 204作为HNB-new提取同步信号的同步源,设定HNB-new获取同步信号的频点为:NB为多载波时选择NB 204的主频点;NB为单载波时,选择NB的频点。HNB-new在需要进行同步的时刻转换到选定的同步频点上,接收NB 204的下行同步信号,进而产生HNB-new的同步信号。According to the analysis of the signal received at the best position, as shown in Figure 5, the
在选择HNB-new的可用频带和工作频点时,如图5,首先对超出干扰门限401的信号103设置保护间隔501和502,保护间隔应大于等于2个第三代移动通信的信道带宽。分析所有信号的频谱分布,将可用的频带300~307以及对应的频点号ARFCN提取出来。根据HNB-new工作带宽大小:单载波或多载波对应的带宽,在300~307的可选择带宽中选择任意一个与HNB-new工作带宽相匹配的频带作为HNB-new的接入工作频带,频带内对应的频点都可作为HNB-new的工作频点。为系统性能最佳,对多载波应用的HNB-new可优选中间频点作为主频点其他为辅频点。When selecting the available frequency band and operating frequency of HNB-new, as shown in Figure 5, first
300~307频带中的带宽各不相同,在选择HNB-new的工作频点时首先选用300~307中满足HNB-new工作带宽要求的零星分布频带内的频点,譬如图5中301、303、300、306频带内对应的频点,其他较为完整的、较宽的频带304、307、302、305内的频点供后续接入的HNB使用。此选择方法的优点是,可以大大提高后续接入的HNB选择工作频点的效率。The bandwidths in the 300-307 frequency bands are different. When selecting the operating frequency points of HNB-new, first select the frequency points in the sporadic distribution frequency bands in the 300-307 that meet the requirements of the HNB-new operating bandwidth, such as 301 and 303 in Figure 5. , 300, and 306 frequency bands, and the frequency points in other relatively complete and
HNB-new工作在以上选择的频点时,可以保证和现存系统共存时满足性能要求。When HNB-new works at the frequency points selected above, it can guarantee to meet the performance requirements when it coexists with the existing system.
(5)如果在HNB-new支持的全部频段内,不存在空闲的频带,则HNB-new选择最弱电平的NB或HNB且被选择的NB或HNB的带宽大于等于HNB-new所需的带宽内的频点作为HNB-new的工作频点。如果HNB-new是单载波应用并且被选择的HNB或NB设备也是单载波,则HNB-new的识别码应选择有别于HNB或NB的识别码;如果被选择的HNB或NB的是多载波设备,则HNB-new的工作频点选择在HNB或NB的辅频点上。如果HNB-new是多载波应用,则HNB-new的主频点需选择在HNB或NB的辅频点上。(5) If there is no free frequency band in all the frequency bands supported by HNB-new, then HNB-new selects the NB or HNB with the weakest level and the bandwidth of the selected NB or HNB is greater than or equal to the bandwidth required by HNB-new The frequency points within are used as the working frequency points of HNB-new. If HNB-new is a single-carrier application and the selected HNB or NB equipment is also a single-carrier, the identification code of HNB-new should be different from that of HNB or NB; if the selected HNB or NB is multi-carrier equipment, the working frequency of HNB-new is selected on the auxiliary frequency of HNB or NB. If HNB-new is a multi-carrier application, the main frequency point of HNB-new needs to be selected on the secondary frequency point of HNB or NB.
(6)所有已经安装并正常工作的HNB,根据来自接入控制器APC的令,随时启动自主频率配置对周围信号进行扫描。如果用于同步的信号接收质量变差、工作频带内出现干扰,则需重新选择同步源、更新获取同步信号的频率、重新选择频带和工作频点。采用此方法解决了当第三代移动通信系统扩容时基站NB配置发生变化、增加NB站点时,下行同步信号发生变化对HNB的影响。(6) All HNBs that have been installed and work normally, according to the order from the access controller APC, start the autonomous frequency configuration at any time to scan the surrounding signals. If the receiving quality of the signal used for synchronization deteriorates and interference occurs in the working frequency band, it is necessary to re-select the synchronization source, update the frequency for obtaining the synchronization signal, and re-select the frequency band and working frequency point. This method is adopted to solve the influence of the change of the downlink synchronization signal on the HNB when the NB configuration of the base station changes and the NB site is added during the expansion of the third generation mobile communication system.
