无线通信系统中分类区域定位方法 The wireless communication system targeting classification method

技术领域 FIELD

本发明涉及移动通信技术领域,具体涉及一种无线通信系统中分类区域定 The present invention relates to the technical field of mobile communication, particularly relates to a wireless communication system, a given classification regions

4立方法。 4 Li method.

背景技术 Background technique

目前,移动通信正向着以WCDMA(宽带码分多址)为4支术核心的3G(第三代移动通信)系统发展。 Currently, mobile communication is toward to WCDMA (Wideband Code Division Multiple Access) technique as four core 3G (third generation mobile communication) system development. UMTS (通用移动通信系统)是3GPP (第三代移动通信标准化伙伴项目)制定的第三代移动通信系统的标准,其原则是将无线才妾入网和核心网明确分开。 UMTS (Universal Mobile Telecommunications System) standard 3GPP (Third Generation Partnership Project) to develop third-generation mobile communication system, the principle is the only concubine wireless network and core network clearly separated. UMTS网络由两部分组成: 一部分是UTRAN (UMTS Terrestrial Access Network, UMTS陆地无线接入网),另一部分是CN (核心网),这两部分通过Iu4妄口连接。 UMTS network consists of two parts: one is the UTRAN (UMTS Terrestrial Access Network, UMTS Terrestrial Radio Access Network), the other is CN (Core Network), the two parts are connected by Iu4 jump port. UTRAN包4舌多个RNS (无线网络子系统),RNS包括一个RNC (无线网络控制器)和一个或多个Node B (基站)。 4 a plurality of tongue UTRAN packet the RNS (Radio Network Subsystem), RNS comprises a RNC (radio network controller) and one or more Node B (base station). UTRAN结构如图1所示: UTRAN shown in Figure 1:

其中,每个NodeB服务于一个或多个无线小区,提供无线资源的接入功能;RNC相当提供无线资源的控制功能。 Wherein each NodeB serving one or more radio cells, providing access to functions of the radio resources; rather the RNC provides control functionalities of radio resources.

3G除了在带宽方面比2G有明显的提高之外,还可以支持更加丰富的移动增值业务,其中移动定位业务就是其中之一。 In addition to 3G than 2G has increased significantly in terms of bandwidth, it can also support richer mobile value-added services, which mobile positioning service is one of them. 作为无线通信系统的特色业务之一,移动定位在交替监控、车辆导航、紧急救援、定位相关信息的获取等方面有着重要的作用。 As one of the characteristics of business wireless communications systems, mobile positioning in alternate monitoring, vehicle navigation, emergency rescue, location and other aspects related to access to information plays an important role. 在移动通信中,对移动台的定位作为一种移动通信系统的增值业务,其价值正在被运营商和用户所认识。 In mobile communications, positioning of mobile value-added services as a mobile communications system, and its value is being recognized by operators and users.

基于CellID (小区标识)的定位技术是一种最基本的定位方法,适用于所有的蜂窝网络。 Based on the CellID (cell identity) location technology is a basic positioning method, applicable to all cellular networks. 它不需要移动台提供任何定位测量信息,也无需对现网进行改动,只要在网络侧增加简单的定位流程处理即可。 It does not need to provide any mobile station location measurement information, there is no need to make changes to the existing network, as long as the positioning process of adding a simple processing to the network side. 它的定位原理是:网络根据 Its positioning principle is: according to the network

移动台当前服务基站的位置和小区覆盖来定位移动台。 Position of the mobile station and a current serving base station cell coverage to locate a mobile station.

在位置服务业务中,存在一种定位服务,在每个RNC的^^作台配置分类区城,即接入网提供给位置区城打"标记"的功能,"标记"后的位置区就是"分类区域"。 Location services business, there is a location-based services, in each ^^ RNC is classified as stage configured City area, namely the access network to the position area city playing the "mark" feature, location area is the "mark" "classification of the area." 比如,某RNC的所属小区覆盖的区域发生传染病,这时就需要对进入这些区域和离开这样区域的移动用户进行监控。 For example, a cell area covered by a RNC belongs to the infectious diseases, then you need to enter these areas and leaving such area the mobile subscriber is monitored.

RNC支持在操作台配置"分类区域",并且将一个分类区域映射为一个或多个服务区域SA, UE出入这些分类区域会触发位置报告。 RNC supports the configuration of "classified area" in the console, and map a classified area for one or more service areas SA, UE access to these classified areas will trigger position report.

根据3GPP标准TS 25.413,当用户进入或者离开一个分类区域时, UTRAN应该向CN发送一条LOCATION REPORT (位置报告)消息,消息中包含SAI (服务区标识)和CAUSE原因值信元,以SAI (服务区标识)表示UE (用户设备)所在的服务区域,而CAUSE (原因值)信元则应注明"User Restriction Start Indication"(用户卩艮制开始指示)或者"User Restriction End Indication"(用户限制结束指示)。 25.413, when a user enters or leaves a classification region, the UTRAN should be transmitted according to the 3GPP standard TS to the CN a LOCATION REPORT (Report) message, which contains the SAI (Service Area Identity) and CAUSE cause value cell, to the SAI (Service area identification) indicates UE (user equipment) service region is located, and the CAUSE (Cause value) information element should be marked "user restriction start indication" (manufactured by Gen Jie user instruction to start) or "user restriction End indication" (user restrictions end instruction). CN则根据运营商规定的策略对该位置报告进4亍相应处理。 CN 4 right foot into the appropriate treatment strategy based on the location of the reports specified operator.

LOCATION REPORT (位置报告)消息的发送流程如图2所示: 小区l被设置为分类区域,小区2不是分类区域。 Send flow LOCATION REPORT (Report) message shown in Figure 2: l are set to the class cell area, the cell area 2 is not classified.

UE (用户设备)从小区1接入后,RNC触发分类区域定位判决,判决UE 接入的小区是分类区域,向核心网上报位置报告,消息中包含了小区1所属的SAI ,以及原因<i "User Restriction Start Indication"。 UE (user equipment) access from a cell, the RNC is triggered positioning classification regions which held the UE accesses the cell is classified areas, Location Reporting message to the core network, the message contains a cell belongs to SAI, and why <i "User Restriction Start Indication".

然后,UE从小区1切换到小区2,切换完成后,RNC触发分类区域定位判决,判决小区2不是分类区域,RNC向核心网上报位置报告,消息中包含小区1所属的SAI,以及原因值"User Restriction End Indication"。 Then, the UE handover from the cell 1 to cell 2, after the completion of the handover, the RNC is triggered classification regions positioning decision, the decision cell 2 is not classified areas, the RNC core network packet location report to the message contains the cell 1 the SAI belongs, and the cause value " User Restriction End Indication ".

现有技术方案需要在无线接入侧为每个RNC分别配置分类区域,操作上比较困难。 Prior art solutions require classification regions are arranged to each RNC in the radio access side, the operation is difficult. 一般一个核心网下面连接多个RNC,如图3所示,如果需要配置的分类区域跨越多个RNC,则需要在每个RNC的操作台为RNC分别进行配 Usually a plurality of core network RNC connecting the following, shown in Figure 3, if the classification regions to be configured across a plurality of RNC, the RNC are required with each RNC in the console

置,比如,RNC-1所属的小区Celll和RNC-2所属的小区Cell2需要配置为分#区域。 It is set, for example, cells Celll RNC-1 belongs and the RNC-2 cell belongs Cell2 be configured as sub-zone #.

如果某个UE原来连接在RNC-l,即RNC-1是其SRNC(服务RNC),当UE移动到RNC-2 (CRNC,控制RNC )所属的小区Cel12时,如果没有发生迁移的情况下,SRNC和CRNC分离,RNC-1仍然是SRNC,RNC-2成为DRNC (漂移RNC),如果不事先在RNC-1配置RNC-2所属小区的分类区域的情况下,RNC-1不知道该UE是否处于分类区域中,也就无法对UE所处的分类区域进行定位。 If a UE is connected to the original RNC-l, i.e., RNC-1 which is the SRNC (serving RNC), when the UE moves to RNC-2 (CRNC, the control RNC) Cel12 cell belongs, if the situation does not occur under the migration, SRNC and CRNC separation, RNC-1 remains SRNC, RNC-2 becomes the DRNC (drift RNC), if not previously in the case of RNC-1 configuration RNC-2 belongs to a cell classification regions, RNC-1 does not know whether the UE in classified areas, the classification will not be able to locate the area in which the UE.

发明内容 SUMMARY

本发明的目的是提供一种无线通信系统中分类区域定位方法,以克服现有技术中由无线网络控制器配置分类区域的方式,以及在服务RNC和控制RNC 分离的情况下无法对UE进行分类区域定位的缺陷。 Object of the present invention is to provide a radio communication system classification regions positioning method to overcome the prior art embodiment is configured by a radio network controller classification regions, and the UE can not be classified in the case where the serving RNC and controlling RNC isolated targeting defect.

具体实施方式 detailed description

本发明的核心在于在无线通信系统中,由核心网统一对其连接的多个RNC 进行分类区域配置,向RNC指示本CN节点的服务区域中所有SAI与CZ1的对应关系,RNC根据这些对应关系即可得知其所属CN节点的服务区中所有的SAl, 并且根据这些对应关系判决其下所有UE的服务小区是否属于分类区域,如果属于分类区域,则准备位置报告,报告中的位置信息为当前小区的SAI,并指示原因为"User Restriction Start Indication"。 The core of the present invention is a wireless communication system, a core network by the unified classification region configuration plurality thereof connected to the RNC, indicates the service area of ​​this CN node CZ1 all correspondence between the SAI to the RNC, the RNC according to a correspondence relationship that it belongs to the CN node service area of ​​all SAl, and the judgment whether all UE under the serving cell belongs to the classification region, if the area of ​​the class, is prepared according to the corresponding relationship between the location report, the position information in the report is current cell SAI, and indicate the reason for the "User Restriction Start indication". 然后,向CN发送LOCATION REPORT报告。 Then, send LOCATION REPORT report to CN.

RNC在小区改变的时候,判断是否分类区域变化。 When the cell change RNC, determines whether the change of classification regions. 比如,用户移动时,可能触发小区间切换,从一个小区进入另一个小区,RNC判断新进入的小区是否是分类区域,以此判断是否发生分类区域变化。 For example, when the user moves, it may trigger the inter-cell handover from one cell into another cell, determining whether the new RNC is classified into the cell area in order to determine whether the classification region changes.

当用户离开某分类区域时,位置报告内容为离开小区所属的SAI,原因值为"User Restriction End Indication";如果是进入某分类区域,位置报告内容为进入小区所属的SAI,原因值为"User Restriction Start Indication"。 When the user leaves a certain area classification, location content is reported to leave the cell belongs to SAI, the cause value "User Restriction End Indication"; if it is to enter a classification region, to enter the cell location reporting content belongs SAI, the cause value "User Restriction Start Indication ".

为了使本技术领域的人员更好地理解本发明方案,下面结合附图和实施方式对本发明作进一步的详细说明。 In order to make those skilled in the art a better understanding of the invention, The present invention will be described in further detail in conjunction with the accompanying drawings and embodiments.

参照4所示的本发明方法的流程图,包括以下步骤: The method of the present invention with reference to a flowchart shown in FIG. 4, comprising the steps of:

步骤401:由核心网向无线网络控制器配置核心网服务区域中的分类区„ Step 401: Configure a core network service classification zone area to the radio network controller from the core network. "

本技术领域人员知道,终端的网络搜索技术与其使用的无线网络制式有关,也就是说,CDMA2000终端、GSM (全球移动通信系统)终端、WCDMA In the art will appreciate that a wireless network using standard Internet search technology of the terminal related thereto, i.e., CDMA2000 terminals, GSM (Global System for Mobile Communications) terminal, WCDMA

(宽带码分多址)终端的网络搜索过程是不完全相同的。 The network search (Wideband Code Division Multiple Access) terminals are not identical. 但其服务区的构成是相同的。 But it constitutes its service area is the same.

例如,在WCDMA系统中,终端在开机或脱网时,首先由PLMN(公众陆地移动网)选择过程通过自动或手动方式选择一个PLMN,然后搜索属于该PLMN的小区,如果在该PLMN下无法捕捉到合适的小区,则将在小区搜索过程中得到的可捕获PLMN列表报告给PLMN选择过程,由其重新选择PLMN, 启动新一轮小区捕获过程。 For example, in a WCDMA system, when the terminal is switched on or off-grid, first by PLMN (Public Land Mobile Network) selection procedure to select a PLMN through automatic or manual mode, and then search belonging to the PLMN, the cell can not be captured if this PLMN to a suitable cell, then the cell search procedure can be obtained in the list of reports to capture PLMN PLMN selection process, its re-select the PLMN, start a new round of cell acquisition process.

PLMN由MCC (Mobile Country Code,移动国家代码)和MNC (Mobile Network Code,移动网络代码)共同唯一确定。 PLMN is uniquely identified by the MCC (Mobile Country Code, Mobile Country Code) and MNC (Mobile Network Code, Mobile Network Code). 其中,MCC标识GSM PLMN 所在国家,其值与IMSI (国际移动用户识别码)中的头3位的MCC相同。 Wherein, GSM PLMN country identifier MCC, MCC value and the same IMSI (International Mobile Subscriber Identity) in the head 3 bits. MNC 用于标识该国中的各GSM PLMN,其值与IMSI中紧接着MCC的2或3位的MNC 相同。 MNC identifies each GSM PLMN in that country, followed by the same 2 or 3 MCC MNC of the IMSI in the value.

PLMN通常由很多个小区组成。 PLMN usually it consists of a number of cell components. 小区是移动通信网络中的最小覆盖单元, 是由其使用的主扰码惟一标识的,该主扰码在网络规划时即已分配给小区。 Cell is the smallest unit of the mobile communication network coverage is its unique primary scrambling codes used for identification of the primary scrambling codes already assigned to a cell in the network planning. 小区所属的PLMN的信息包含在其下发的系统消息中。 PLMN information of the cell contained in the system belongs to a message issued in its.

标准规定,服务区域的构成如下:SAI = PLMN-Id + LAC + SAC,其关系^口图5所示:其中, Standards, constituting the service area is as follows: SAI = PLMN-Id + LAC + SAC, the relationship shown in FIG. 5 ^ port: wherein,

SAI用来唯一标识由同属于某一相同LA (位置区域)的一个或多个小区组成的区域,这个区域被称作服务区并且能被用来指示位置区中UE所在的位置。 SAI uniquely identified by the same region of one or more cells belong to a same LA (Location Area) composition, this region is called the service area and can be used to indicate the position of the UE is located in the location area. 其中: among them:

PLMN-Id为公众陆地移动电话网标识码。 PLMN-Id is public land mobile telephone network identification code.

LAC (Location Area Code,位置区域码):是长度固定为2个8位字节的码字,用以标识GSM PLMN中的一个LA (位置区)。 LAC (Location Area Code, Location Area Code): is a fixed length of two 8-bit bytes of codeword for identifying the GSM PLMN in a LA (Location Area). 这部分位置区标识可以用一个完整的十六进制表示法来编码,但不能表示为0000或FFFE ,因为这 This part of the location area identifier can be a complete encoded hexadecimal notation, but can not be expressed as 0000 or FFFE, because it

两个保留值被用于MS (移动台)中无有效的LAI (位置区域指示)存在的特歹朱情况。 Two values ​​are used to retain the MS (mobile station) is no valid LAI (location area indicated) Zhu Laid presence of bad. LAC由运营商定义,通过0&M (操作管理)在RNC内设置。 LAC is defined by the operator, provided by the RNC 0 & M (operations management).

SAC ( Servise Area Code,服务区域码):是固定长度为2个8位字节的码字。 SAC (Servise Area Code, Service Area Code): is a fixed length of 2 bytes of 8-bit code word.

步骤402:无线网络控制器根据配置信息判断用户是否离开或者进入分类区域。 Step 402: The radio network controller determines whether the configuration information of the user leave or enter classification regions.

当UE开机后或在漫游中,它的首要任务就是找到网络并和网络取得联系, 只有这样才能获得网络的服务。 When the UE is powered on or in roaming, its primary task is to find the network and network and get in touch, the only way to get network services. UE在空闲模式下的行为可以细分为PLMN选择和重选,小区的选择和重选和位置登记三个过程。 Behavior of the UE in idle mode may be subdivided for the PLMN selection and reselection, selection and reselection and cell location registration of three processes.

当UE开机后,首先应该选择一个PLMN。 When the UE is powered on, you should first select a PLMN. 当选中了一个PLMN后,就开始选择属于这个PLMN的小区。 After the election in a PLMN, he began to select a cell belonging to the PLMN. 当找到这样的一个小区后,从系统信息(广播) 中就可以知道临近小区的信息。 After finding such a cell from the system information (broadcast) you can know the information in adjacent cells. 这样UE就可以在所有这些小区中选择一个信号最好的小区驻留下来。 Thus the UE can select a cell to camp on the best signal down all of these cells. 紧接着UE就会发起位置登记过程,成功后UE就成功的驻留在这个小区中了。 Then UE will initiate a location registration procedure, the UE after the success of this success resides in the cell.

驻留的作用有4个: There are four action resides:

使UE可以接收PLMN广播的系统信息;可以在小区内发起随机接入过程; 可以接收网络的寻呼;可以接收小区广播业务。 So that the UE may receive system information broadcasted PLMN; may initiate a random access procedure in a cell; may receive a paging network; may receive cell broadcast service.

当UE驻留在小区中并登记成功后,随着UE的移动,当前小区和临近小区的信号强度都在不断变化。 When the UE camping in a cell and the registration is successful, as the mobile UE, the current cell and signal strength of adjacent cells are constantly changing. UE就要选择一个最合适的小区,这就是小区重选过程。 UE should choose the most suitable cell, which is the cell reselection process. 这个最合适的小区不一定是当前信号最好的小区,因为,比如UE处在一个小区的边缘又在这两个小区之间来回走,恰好这两个小区又是属于不同的LA (位置区)或者RA (路由区),这样UE就要不停的发起位置更新,既浪费了网络资源又浪费了UE的能量。 The most suitable cell is not necessarily the best cell of the current signal, as such a cell edge UE is in and go back and forth between two cells, the two cells is exactly belong to different LA (Location Area ) or RA (routing area), so we must keep the UE initiates a location update, a waste of network resources and a waste of energy UE. 因此,在所有小区中重选哪个小区是有一定规则的。 Therefore, in all the cells in which cell reselection is a certain rule. 当UE重选小区,选择了另外一个小区后,发现这个小区属于另外一个LA或者RA, UE就要发起位置更新过程,使网络获得最新的UE的位 When the UE reselects a cell, another cell is selected, a further found that the cell belongs to the RA or LA, UE initiates a location update procedure is necessary to make the network to obtain the latest position of the UE

置信息。 Configuration information.

在任何情况下,如果UE的服务小区改变,都应该触发分类区域的判决, 也就是说要判断UE是吝离畀成者进入分类区城。 In any case, if the UE's serving cell change, the decision should trigger classification region, that is to determine the UE is stingy to give her away from entering the city area classification. 导致UE服务小区改变的过程包括: Process leading to UE serving cell changes include:

小区更新;URA (用户注册区域)更新;RRC (无线资源控制)连接建立;切换(软切换、硬切换、系统间切换)完成。 A cell update; URA (User registration area) update; the RRC (radio resource control) connection establishment; handover (soft handover and hard handover, inter-system handover) is completed.

RNC在小区改变的时候,判断是否分类区域发生变化。 When the cell change RNC determines whether to change the classification region. 如图3,假设小区l是分类区域,小区2不是分类区域,UE通过RRC连接建立在小区1,然后UE从小区1切换到小区2。 3, l is assumed that the cell classification region, the cell region 2 is not classified, the RRC connection establishment by UE in the cell 1, then the UE from the cell 1 to cell 2. 当UE接入小区1时,RNC上报位置报告给核心网,消息中带小区1所属的SAI信息,以及原因值"User Restriction Start Indication",当UE切换到小区2时,RNC判断UE离开了分类区域,上报位置报告给核心网,消息中带小区1所属的SAI信息,以及原因值"User Restriction End Indication"。 When the UE accesses the cell 1, the RNC reports the location report to the core network, the message with the SAI information belongs cell 1, and the cause value "User Restriction Start Indication", when the UE 2 switch to the cell, the RNC determines the UE leaves a Classified region, to the core network reports the location report, the SAI information in the message with a cell belongs, and the cause value "User Restriction End Indication".

判断用户是否离开或者进入某分类区域,对于SRNC的覆盖区域内的小区相关信息(如该小区所属的服务区SAI)可以从SRNC的数据库中获得,即UE进入或离开SRNC所管理的小区,SRNC获得该小区所属的SAI信息,然后根据CN为其配置的SAI和分类区域CZI的映射关系,如果该小区的SAI 存在对应的CZI,表明该小区是分类区域,进入或离开该小区都触发位置报告。 Determining whether the user leave or enter a classification region, for the cell-related information within the coverage area of ​​the SRNC (such as a service SAI which the cell belongs) can be obtained from the SRNC database, i.e. the UE enters or leaves the SRNC manages a cell, SRNC SAI is obtained information of the cell belongs, and mapping relationship of the SAI CN CZI and classification regions for configuration, if there is a corresponding SAI of the cell CZI, indicating that the cell is a classification regions, to enter or leave the cell are triggered location reporting .

即进到步骤403:当用户离开或者进入分类区域时,触发位置报告给核心网。 I.e., proceeds to Step 403: When a user leave or enter the classification zone, the Triggered Location Reporting to the core network.

如果是离开某分类区域时,位置报告内容为离开小区所属的SAI,原因值"User Restriction End Indication"(用户限制结束指示);如果是进入某分类区域,位置报告内容为进入小区所属的SAI,原因值为"User Restriction Start Indication"(用户限制开始指示)。 If you leave a classification region, content location report away SAI cell belongs, the cause value "User Restriction End Indication" (user restricted end instruction); if it is to enter a classification region, the position of the report to enter SAI cell belongs, Cause value "user restriction start indication" (user restrictions start instruction).

参照图6所示的跨RNC的UE连接示意图:对于UE进入或离开不属于SRNC管理的小区,与CN相连的是SRNC, 而小区所属NodeB (基站)由DRNC控制,该小区的服务区信息一般不会在SRNC配置,但在建立跨SRNC与DRNC之间的Iur接口的链路时,DRNC会将所建链路小区以及它的相邻小区信息通过响应消息带给SRNC,也就是说可以通过SRNC和DRNC之间的Iur接口的无线链路建立/增加过程中的响应消息,将该UE在DRNC所处小区,以及该小区相邻小区的服务区信息(包括SAI)带给SRNC, SRNC可以保存在临时内存或数据库中,用于UE在DRNC 的服务区域内移动时,判断是否离开或者进入分类区域。 Referring to FIG. 6 a schematic cross-RNC connected to the UE: UE for entering or leaving the cell does not belong to the management SRNC, SRNC is connected with the CN, and the cell belongs NodeB (base stations) controlled by the DRNC, the cell's service area information is generally will not SRNC configuration, but in establishing a link Iur interface between the SRNC and across the DRNC, DRNC will link the cell and its neighboring cell information to build a response message to bring SRNC, that is to say through radio link Iur interface between the SRNC and the DRNC setup / addition response message during the service area information of the cell (including SAI) of the UE in the DRNC neighboring cell is located, and give the cell SRNC, SRNC can stored in the temporary memory or a database, for moving within the service area DRNC, the UE determines whether or not to leave or enter the classification zone.

参照图2,假设小区2属于图6中DRNC所属的小区,当SRNC执行UE 从小区1切换到小区2时,首先通过kir接口请求DRNC建立无线链路,DRNC 完成基站和RNC之间的Iub接口的无线链路建立后,返回SRNC的Iur接口的无线链^^建立响应,消息中带小区2以及该小区相邻小区的服务区信息(包括SAI); Referring to FIG 2, assuming that the cell belongs to the cell 2 in FIG. 6 belongs DRNC, SRNC when the UE 2 performs, first establish a radio link through the DRNC kir interface requests handover from the cell 1 to the cell, the DRNC to complete the Iub interface between the RNC and the base stations after establishing a radio link, the SRNC returns Iur interface ^^ radio link setup response message with the cell in the service area 2, and information of the neighboring cells (including the SAI);

SRNC保存小区2的SAI信息; SAI information stored SRNC cell 2;

SRNC完成切换后,判决分类区域是否改变,这时根据保存的从Iur接口带回的SAI信息,可以判决小区2不是分类区域。 SRNC after completing the handover, the decision whether to change the classification region, this time in accordance with SAI Iur interface information from the saved back, cell 2 may decide not classified areas.

步骤404:核心网根据位置报告获取用户所在的分类区域。 Step 404: The core network to obtain classified according to the position of the user's locale report.

CN根据位置报告中的位置信息SAI和原因值"User Restriction End Indication"或"User Restriction Start Indication", CN可以4口道i亥UE是否进入了某个分类区或离开某个分类区域。 CN SAI and the position information in the Location Reporting cause value "User Restriction End Indication" or "User Restriction Start Indication", CN four channel i can Hai UE whether to enter a certain area or leave a classification of classification regions.

本发明与现有技术的区别主要在于由核心网向无线网络控制器配置核心网服务区域中的分类区域,使分类区域由核心网统一管理,使得操作简单,并且解决了SRNC和CRNC分离情况下分类区域的定位问题。 The difference between the present invention and the prior art mainly configured by the core network to the radio network controller, core network service area classification area, so that the unified classification regions by the core network management, so that the operation is simple, and solves separation the SRNC and CRNC positioning of classification region.
