Description

具有微微基站的无线电接入网的寻呼 The radio access network with pico base station paging

技术领域 FIELD

[0001 ] 本发明涉及无线电信,具体来说,涉及具有“微微”或“毫微微”无线电基站的无线电接入网中的寻呼。 [0001] The present invention relates to wireless telecommunications, and in particular, relates to a "Pico" or "femto" radio base station of the radio access network paging.

背景技术 Background technique

[0002] 在典型的蜂窝式无线电系统中,无线用户设备单元(UE)经无线电接入网(RAN)与一个或多个核心网络进行通信。 [0002] In a typical cellular radio system, wireless user equipment unit (UE) via a radio access network (RAN) communicate with one or more core networks. 用户设备单元(UE)可以是移动台,例如移动电话(“蜂窝”电话)和具有移动终端的膝上型计算机,因而可以是例如便携、袖珍、手持、计算机内置或者车载移动装置,它们与无线电接入网进行语音和/或数据通信。 User equipment unit (UE) may be a mobile station, such as mobile telephones ( "cellular" telephones) and laptops with mobile termination, and thus can be, for example, portable, pocket, handheld, computer-included, or car-mounted mobile devices which the radio access network for voice and / or data communications. 或者,无线用户设备单元可以是固定无线装置,例如作为无线本地环路的组成部分的固定蜂窝装置/终端等。 Alternatively, the wireless user equipment units can be fixed wireless devices, such as fixed cellular components of the apparatus in a wireless local loop / terminals.

[0003] 无线电接入网(RAN)覆盖分为若干小区的地理区域,其中各小区由基站提供服务。 [0003] radio access network (RAN) covers a geographical area divided into a plurality of cells, wherein each cell served by a base station. 小区是由基站站点处的无线电基站设备提供无线电覆盖的地理区域。 A cell is a geographical area where radio coverage of a radio base station equipment at a base station site. 各小区通过在小区中作为系统信息广播的唯一识别码来标识。 Each cell is identified by a unique identification code in a cell as a system information broadcast. 基站通过空中接口与基站范围内的用户设备单元(UE)进行通信。 The base stations communicate by a user equipment unit (UE) within range of the base station air interface. 在无线电接入网中,若干基站通常(例如通过陆线或微波)连接到无线电网络控制器(RNC)。 In the radio access network, several base stations are typically (e.g., by landlines or microwave) to radio network controller (RNC). 无线电网络控制器有时也称作基站控制器(BSC),它监控并协调所连接的多个基站的各种活动。 The radio network controller, also sometimes referred to as a base station controller (BSC), it monitors and coordinates various activities of the plural base stations connected. 无线电网络控制器通常连接到一个或多个核心网络。 The radio network controllers are typically connected to one or more core networks. 核心网络具有两个服务域,其中RNC具有与这两个域的接口。 The core network has two service domains, in which the RNC has interfaces with these two domains.

[0004] 无线电接入网的一个实例是通用移动电信系统(UMTS)陆地无线电接入网(UTRAN)。 [0004] One example of a radio access network is the Universal Mobile Telecommunications System (UMTS) Terrestrial Radio Access Network (UTRAN). UMTS是第三代系统,在某些方面是以欧洲开发的称作全球移动通信系统(GSM)的无线电接入技术为基础的。 UMTS is a third generation system, in some respects is developed in Europe called Global System for Mobile (GSM) radio access technology basis. UTRAN本质上是向用户设备单元(UE)提供宽带码分多址(WCDMA)的无线电接入网。 UTRAN is essentially a wideband code division multiple access is provided (WCDMA) to user equipment unit (UE) radio access network. 第三代合作伙伴项目(3GPP)已经着手进一步发展UTRAN和基于GSM的无线电接入网技术。 Third Generation Partnership Project (3GPP) has undertaken to evolve further UTRAN and GSM-based radio access network technologies of.

[0005] 本领域的技术人员理解,在WCDMA技术中,公共频带允许用户设备单元(UE)和多个基站之间同时通信。 Simultaneous communication between [0005] Those skilled in the art will appreciate, in a WCDMA technique, a common frequency band allows the user equipment unit (UE) and a plurality of base stations. 在接收站通过基于使用高速伪噪声(PN)码的扩频CDMA波形特性来区别占用公共频带的信号。 Based on the receiving station using a high speed pseudonoise spread spectrum CDMA waveform properties (PN) code to distinguish common frequency band occupied by the signal. 这些高速PN码用来调制从基站和用户设备单元(UE)发射的信号。 These high speed PN codes used to modulate signals transmitted from the base station and the user equipment unit (UE). 使用不同PN码(或时间上偏移的PN码)的发射机站产生能够在接收站单独被解调的信号。 Generating a signal can be separately demodulated at a receiving station using different PN codes (or a PN code offset in time) of the transmitter station. 高速PN调制还允许接收站方便地通过结合发射信号的若干不同传播路径从单个发射站产生接收信号。 High speed PN modulation also allows the receiving station to easily generate a received signal from a single transmitting station by binding a plurality of different propagation paths of the transmitted signal. 因此,在CDMA中,在从一个小区到另一个小区进行连接切换时,用户设备单元(UE)不需要转换频率。 Thus, in CDMA, at the time of connection switching from one cell to another cell, the user equipment unit (UE) does not need frequency conversion. 这样,在始发小区继续为连接提供服务的同时,目标小区可支持与用户设备单元(UE)的连接。 Thus, in the originating cell while continuing to provide connection services, the target cell may support connections with user equipment unit (UE) a. 由于用户设备单元(UE)在切换过程中始终通过至少一个小区进行通信,因此呼叫没有中断。 Since the user equipment unit (UE) in the handover process always communicate via at least one cell, so the call is not interrupted. 因此称作“软切换”。 So called "soft handoff." 与硬切换相比,软切换是“中断前进行的”转换操作。 Compared with the hard handover, soft handover is a conversion operation "carried out before the interruption."

[0006] 包含无线电接入网的其它类型的电信系统包括:全球移动通信系统(GSM);高级移动电话服务(AMPS)系统;窄带AMPS系统(NAMPS);全接入通信系统(TACS);个人数字蜂窝(I3DC)系统;美国数字蜂窝(USDC)系统;以及EIA/TIA IS-95中描述的码分多址(CDMA)系统。 [0006] include other types of telecommunication systems radio access network include: Global System for Mobile Communications (GSM); Advanced Mobile Phone Service (AMPS) system; Narrowband AMPS system (NAMPS); Total Access Communication System (TACS); personal digital cellular (I3DC) system; U.S. digital cellular (the USDC) system; and CDMA EIA / TIA iS-95 described in (CDMA) system. [0007] 在UTRAN中存在几种受关注的接口。 [0007] There are several interfaces of interest in the UTRAN. 无线电网络控制器(RNC)和核心网络之间的接口称作“ Iu ”接口。 Between the radio network controller (RNC) and the core network interface called "Iu" interface. 无线电网络控制器(RNC)及其基站(BS)之间的接口称作“ Iub ”接口。 Between the radio network controller (RNC) and its base station (BS) is referred to an interface "Iub" interface. 用户设备单元(UE)和基站之间的接口称作“空中接口”或“无线电接口”或者“Uu接口”。 Between a user equipment unit (UE) and a base station interface called "air interface" or the "radio interface" or "the Uu Interface." 在某些情况下,连接涉及源和服务RNC (SRNC)以及目标或漂移RNC (DRNC),其中SRNC控制连接,但连接的一个或多个多样分支由DRNC处理。 In some cases, the source is connected and services involving the RNC (SRNC) and a target or drift RNC (DRNC), wherein the SRNC controlling the connection but with one or more connections by the diversity branch processing DRNC. RNC间传输链路可用于源RNC和漂移或目标RNC之间的控制和数据信号的传输,并且可以是直接链路或者逻辑链路。 Inter-RNC transport link can be used to transmit control and data signals between Source RNC and a Drift or Target RNC, and may be a direct link or a logical link. 无线电网络控制器之间(例如服务RNC (SRNC)与漂移RNC(DRNC)之间)的接口称作“ Iur”接口。 Between radio network controllers (e.g., the service RNC (SRNC) between the drift RNC (DRNC) and) interface referred to as "Iur" interface.

[0008] 无线电网络控制器(RNC)控制UTRAN。 [0008] Radio Network Controller (RNC) controls the UTRAN. 在实现其控制作用中,RNC管理UTRAN的资源。 In achieving its control role, RNC management resources of the UTRAN. 由RNC管理的这类资源其中包括基站发射的下行链路(DL)功率、基站感觉到的上行链路(UL)干扰以及位于基站的硬件。 RNC by such hardware resource management, including base station transmits a downlink (DL) power, the base station felt uplink (UL) interference and base station is located.

[0009] 本领域的技术人员理解,对于某个RAN-UE连接,RNC能够具有服务RNC(SRNC)的作用或者具有漂移RNC (DRNC)的作用。 [0009] Those skilled in the art will appreciate, for a certain RAN-UE connection, the RNC can have the role of the service RNC (SRNC) or the role of a drift has the RNC (DRNC) is. 如果RNC是服务RNC (SRNC),则该RNC负责与用户设备单元(UE)的连接,例如,它完全控制无线电接入网(RAN)中的连接。 If the RNC is a serving RNC (the SRNC), the RNC is responsible for the connection with the user equipment unit (UE), e.g., it is fully controlled radio access network (RAN) connection. 服务RNC(SRNC)连接到核心网络。 Services RNC (SRNC) connected to the core network. 另一方面,如果RNC是漂移RNC(DRNC),则它通过提供与用户设备单元(UE)的连接所需的无线电资源(在漂移RNC(DRNC)控制的小区中)来支持服务RNC(SRNC)。 On the other hand, if the RNC is a radio resource drift RNC (the DRNC), it provides the desired connection by the user equipment unit (UE) (in the cell drift RNC (the DRNC) controlled) to support the service RNC (the SRNC) . 包含漂移无线电网络控制器(DRNC)以及由漂移无线电网络控制器(DRNC)通过Iub接口控制的基站的系统在本文中称作DRNC系统或DRNS。 Comprising a drift radio network controller (DRNC) and a system called a DRNC or DRNS of drift radio network controller (DRNC) via an Iub interface control system of a base station herein. RNC被说成是通过Iub接口与其连接的基站的控制RNC(CRNC)。 RNC is said to be the controlling RNC via a base station connected thereto Iub interface (CRNC). 这个CRNC作用不是UE特定的。 This CRNC role is not UE specific. CRNC其中还负责处理通过Iub接口与其连接的基站中的小区的无线电资源管理。 CRNC is responsible for further processing by the base station radio resource management Iub interface connected thereto in the cell.

[0010] 一些运营商正在调查使用小无线电基站(“RBS”)来为有限数量的用户提供家庭或小区域WCDMA覆盖的可能性,其中小无线电基站(“RBS”)在一些上下文中又称作“毫微微RBS”和/或“家庭RBS”和/或“微微RBS”和/或“微RBS”。 [0010] Some carriers are investigating the use of a small radio base stations ( "RBS") offers the possibility of a home or small area WCDMA coverage for a limited number of users, in which a small radio base stations ( "RBS"), also referred to in some contexts "femto RBS" and / or "family RBS" and / or "femto RBS" and / or "micro RBS". 按照这种调查,小RBS将为终端用户(例如为用户设备单元(UE))提供常规WCDMA覆盖,并且将使用某种基于IP的传输连接到RNC。 In this investigation, the end user will be small RBS (e.g., the user equipment unit (the UE)) provide general WCDMA coverage, and the use of a connection to the RNC IP based transmission. 这样提供的覆盖区域称作“毫微微小区”(以指示覆盖区域比较小)。 This provides a coverage area is referred to as "femtocell" (to indicate that the coverage area is relatively small). 毫微微小区的其它术语包括“微微小区”或“微小区”,它与宏或标准无线电基站(RBS)覆盖的宏小区形成对比。 Other terms include femtocell "picocell" or "microcell", which the macro base station or a radio standard (RBS) in contrast to a macro cell coverage.

[0011] 基于IP的传输的一个备选方案是使用固定宽带接入(例如xDSL、Cable等)将家庭RBS连接到RNC。 [0011] An alternative to IP-based transmission using a fixed broadband access (e.g. xDSL, Cable, etc.) to connect to the home RBS RNC. 另一个备选方案是使用无线宽带接入(例如HSDPA和增强上行链路、或WiMAX)。 Another alternative is to use a broadband wireless access (e.g. HSDPA and enhanced uplink, or WiMAX). 图5更详细地示出两种不同的回程备选方案。 FIG 5 shows in more detail two different backhaul alternatives. 第一个备选方案标记为“xDSL回程”,而第二个备选方案标记为“WiMAX回程”。 The first alternative is marked as "the xDSL return", and the second alternative labeled "WiMAX backhaul."

[0012] 一般来说,普通的WCDMA基站(宏RBS)能够使用基于IP的传输连接到RNC。 [0012] General, Common WCDMA base stations (macro RBS) can be used to connect to RNC IP based transmission. 运营商的工作人员、如拥有或维护无线电接入网(RAN)的宏RBS节点和RNC节点的运营商公司的职员通常安装宏RBS节点。 The operator's staff, if the owner or operator to maintain the company's Radio Access Network (RAN) macro RBS nodes and RNC node staff usually mounted macro RBS nodes. 作为安装的一部分,用宏RNC所连接到的RNC的IP寻址信息(DNS名称、完全合格域名FQDN或IP地址)人工配置宏RBS。 As part of the installation, connected with the macro-RNC to the IP addressing information of the RNC (DNS name, fully qualified domain name FQDN or IP address) configuration macro artificial RBS.

[0013] 相反,毫微微RBS通常由终端用户而不是由网络操作员来安装。 [0013] In contrast, a femto RBS is typically installed by the end user rather than by the network operator. 终端用户还能够将毫微微RBS在地理上从一个地方移动到另一个地方,而无需操作员能够或愿意控制毫微微RBS的重新定位。 The end user can also move the femto RBS from a place to another geographically, without operator able or willing to control the repositioning of the femto RBS. 这种用户指令的重新定位要求:毫微微RBS无论安装或设置在什么位置,它都应当连接到正确的RNC。 This repositioning requires a user instruction: Femto RBS, whether mounted or disposed at any position, it should be connected to the correct RNC. “正确的RNC”或“优选的RNC”在这个方面是控制无线电接入网(RAN)的重叠宏小区的相同RNC。 Same RNC "correct RNC" or "preferred RNC" in this respect is the control of the radio access network (RAN) of overlapping macro cells. [0014] 当毫微微RBS用来增强例如小型或家庭办公(SOHO)环境中的局部覆盖时,它应当专用于该家庭或企业,因为向无线电网络控制器节点(以及移动核心网络)的传输可使用由该家庭或企业本身所提供和付费的传输。 [0014] When used to enhance the femto RBS e.g. small or home office (SOHO) environment partially covering, it should be specific to the home or business, since the radio network controller may transmit to the node (and the mobile core network) use itself provided and paid for by the family or business transfer. 在这种情况下,应当仅允许属于该SOHO或企业的终端访问毫微微无线电基站。 In this case, the terminal should be allowed to access only belonging to the SOHO or enterprise femto radio base station.

[0015] 在一些情况中,终端用户或SOHO购买并可能操作毫微微无线电基站。 [0015] In some cases, the end user may purchase and operate SOHO or the femto radio base station. 在一些情况中,毫微微无线电基站可以是只能服务于有限数量终端用户的一种类型的基站。 In some cases, the femto radio base station can serve only a limited number of end users of one type of base station. 在毫微微无线电基站具有有限容量或能力服务于有限数量用户的情况下,重要的是,毫微微无线电基站资源不随着对于不在的或合格的终端用户的寻呼操作而被消耗。 In the case where the femto radio base stations have a limited capacity or capability to serve a limited number of users, is important, not the femto radio base station as the resource for the end user is not qualified or paging operation is consumed.

[0016] 给定上述考虑因素,并如下面进一步说明的,寻呼操作可在获取终端用户对毫微微无线电基站概念的接受方面起作用。 [0016] Given the above considerations, and as explained further below, it may play a role in the acquisition paging operations end user acceptance of the femto radio base station conceptual aspects.

[0017] 寻呼通常在移动台(MS)(例如用户设备单元(UE))与核心网络之间执行。 [0017] Paging is typically performed between a mobile station (MS) (e.g. a user equipment unit (the UE)) and the core network. 寻呼通常基于在电路交换(CS)域中称作位置区域的概念以及在分组交换(PS)域中称作路由区域的相似概念。 Paging generally based on the concept of circuit switching (CS) domain and the called location area concept in a similar packet switched (PS) domain, called routing area. 在电路交换(CS)域中,对各位置区域提供位置区域识别码(LAI),而在分组交换(PS)域中,对各路由区域提供路由区域识别码(RAI)。 Circuit switched (CS) domain, there is provided a location area identifier (LAI) for each location area, whereas in the packet switched (PS) domain, there is provided a routing area identifier (RAI) to each routing area. 每个MS/UE跟踪它上一次成功执行位置/路由区域更新的最后一个LAI和RAI。 Each MS / UE tracking its last successful execution of the last LAI and RAI location / routing area updates. 无线电接入网(例如GERAN或UTRAN)在系统信息中对各小区广播LAI和RAI。 Radio access network (e.g. GERAN or UTRAN) each cell of the broadcast LAI and RAI information in the system. MS/UE则可将这个LAI/RAI与前一个进行比较,并且如果它们不相同,则触发位置/路由区域更新过程。 MS / UE may be the LAI / RAI is compared with the previous, and if they are not identical, the location / routing area update procedure is triggered.

[0018] 核心网络在位置(和路由)区域级别上跟踪MS/UE位置。 [0018] The core network trace MS / UE location on the position (and routes) regional levels. 这意味着,当MS/UE端接过程将要开始时,网络需要在整个位置区域中正常寻呼MS/UE。 This means that, when the MS / UE termination process to be started, the normal paging network needs to MS / UE in the whole location area.

[0019] 因此要理解,位置(和路由)区域规划是网络配置的重要部分。 [0019] It is therefore understood, the position (and routes) regional planning is an important part of the network configuration. 位置(和路由)区域规划极大地影响网络性能,因为例如在大位置区域中,MS/UE不需要频繁地执行位置(和路由)区域更新。 Position (and routes) regional planning greatly affect network performance, since a large location area e.g., MS / UE does not need to perform a location (and routing) areas frequently updated. 但是作为一个相关的缺点,当位置(和路由)区域很大时,寻呼区域也非常宽广。 But as a drawback associated, when the position (and route) large area, the paging area is also very broad. 在这种情况下,一个寻呼操作将需要对多个BSC/RNC和基站/小区执行。 In this case, a paging operation would need to be performed for a plurality of BSC / RNC and the base station / cell. 另一方面,小位置区域意味着MS/UE很可能要更频繁地执行位置(和路由)区域更新,但是在相反的意义上,寻呼操作的幅度更为优化。 On the other hand, the position of the small area means that MS / UE is likely to perform position (and routing) area updated more frequently, but in the opposite sense, the magnitude of the paging operations more optimized. 但是,在毫微微系统中,当终端用户/毫微微操作员安装毫微微无线电基站时,位置(和路由)区域的处理完全不同。 However, the femto system, when the end user / operator of the femto femto radio base station installed, the processing position (and routing) areas completely different.

[0020] 寻呼处理是成问题的,并且严重缺乏具有毫微微无线电基站的WCDMA系统。 [0020] paging processing is problematic, and have a serious lack of a WCDMA system of the femto radio base station. 这些问题和困惑的主要原因如下所述: The main reason for these problems and puzzles as follows:

[0021] 优选地,在WCDMA网络中,宏小区覆盖和毫微微无线电基站小区覆盖没有相同的LAI/RAI。 [0021] Preferably, in a WCDMA network, the macro cell coverage and the femto cell radio base station coverage is not the same LAI / RAI. 与宏小区相比,毫微微小区需要截然不同的LAI/RAI标识符,以便为毫微微无线电基站提供适当的访问控制,并确保访问毫微微RBS的MS/UE始终向核心网络发起位置更新。 Compared with the macro cell, a femto cell requires distinct LAI / RAI identifiers, in order to provide appropriate access control femto radio base station, and to ensure access to the Femto RBS MS / UE always initiates a location update to the core network.

[0022] 优选地,对于连接到毫微微无线电基站的MS/UE的寻呼无需发送给所有毫微微无线电基站。 [0022] Preferably, for connecting to the femto radio base station of the MS / UE paging need not be sent to all the femto radio base station. 在所有毫微微无线电基站中寻呼连接到一个特定毫微微无线电基站的MS/UE会在将毫微微无线电基站连接到RNC的回程部分产生极大的业务量,并使可用总带宽降级。 In all the femto radio base station connected to a particular paging femto radio base station MS / UE will femto radio base station connected to the backhaul portion of the RNC a tremendous amount of traffic and the available total bandwidth degraded. 在一些情况下,回程也由终端用户付费和提供,并且还用于其它目的。 In some cases, the return and also paid by the end user, and also for other purposes.

[0023] 最初看起来,对寻呼困境的简单解决方案是给各毫微微无线电基站分配它自己的LAI (和RAI)。 [0023] Initially looks simple solution paging dilemma is to assign its own LAI (and RAI) to each of the femto radio base station. 但是,给每个毫微微无线电基站分配唯一的LAI和RAI也成问题。 However, each of the femto radio base station to assign a unique LAI and RAI is also problematic. 例如,每个公共陆地移动网络(PLMN)的不同LAI的最大数量为65535。 For example, the maximum number of different LAI of each public land mobile network (PLMN) is 65535. 可用于处理毫微微无线电基站的LA标识符的数量更少,因为相同的LAI空间也用于宏网络。 LA number available for processing the femto radio base station identifiers less, because the same LAI space for the macro network. 另外,给每个毫微微无线电基站分配唯一LAI将施加很大的操作和维护(0&M)开销(相当多的0&M任务)。 Further, each of the femto radio base station to assign a unique LAI applying large operation and maintenance (0 & M) overhead (0 & M considerable number of tasks). 因此,LAI/RAI需要在毫微微无线电基站之间再用。 Thus, LAI / RAI then required between the femto radio base station.

[0024] 因此,所需的以及本文所提供的目标是用于提供对无线电接入网中的毫微微无线电基站的有效寻呼控制的方法、技术、装置或系统。 [0024] Accordingly, provided herein and the target is required to provide a method for efficiently paging radio access network, the femto radio base station control technology, device or system.

[0056] 作为描述寻呼控制数据库46的使用的序言,描述无线电接入网的其它初步操作是有用的。 [0056] described as a prelude to using a paging control database 46, other preliminary operations described radio access network is useful. 在图1A所示的时间,用户设备单元(UE) 30正设法经由毫微微无线电基站28fj访问无线电接入网24。 At time shown 1A, the user equipment unit (UE) 30 is trying to access the femto radio base station via a radio access network 24 28fj. 毫微微无线电基站28fj已经由毫微微操作员激活,并且已经连接到正确的无线电网络控制器节点(例如无线电网络控制器262)。 28fj femto radio base station has been activated by a femto operator, and has been connected to the correct radio network controller node (e.g. a radio network controller 262). 毫微微无线电基站28fj可通过各种方式连接到正确的无线电网络控制器节点。 28fj femto radio base station can be connected to the correct radio network controller node in various ways.

[0057] 在设法经由毫微微无线电基站28fj访问无线电接入网24时,用户设备单元30尝试使用毫微微无线电基站28fj访问无线电接入网24,在图1A中一般由事件或步骤S-1A表示。 [0057] In trying to access the femto radio base station via a radio access network 28fj 24, the user equipment unit 30 attempts to use the femto radio base station 24 28fj access a radio access network, typically represented by an event S-1A in FIG. 1A or steps . 用户设备单元30尝试使用毫微微无线电基站28fj访问无线电接入网24的一个示例方式是用户设备单元30尝试通过毫微微无线电基站28fj与无线电接入网24建立无线电资源控制(RRC)连接(RRC连接建立)。 30 using the user equipment unit attempts to access the femto radio base station 28fj an exemplary embodiment is a radio access network 24 the user equipment unit 30 and the radio access attempt by the femto radio base station 28fj network 24 establishes a radio resource control (RRC) connection (RRC Connection set up).

[0058] 参照图6进一步描述(作为子步骤)图1A的步骤S-1A的动作和区域更新过程。 [0058] further described with reference to FIG. 6 (a sub-step) and the operation area update procedure of step S-1A of FIG. 1A. 图6示出,作为子步骤S-1A-1,候选用户设备单元30正设法预占毫微微无线电基站28fJ的小区,并在进行这种操作时,候选用户设备单元30检测在毫微微无线电基站28fj的小区Cfj中广播的新的网络区域标识符(例如新的LAI)。 Figure 6 shows, as a sub-step S-1A-1, the candidate user equipment unit 30 is trying camped femto-cell radio base station 28fJ and during this operation, the user equipment unit 30 detects candidate femto radio base station the new network area identifier (e.g. new LAI) in Cfj 28fj cell broadcast. 新的网络区域标识符是与(位置)更新过程成功的先前LAI不同的LAI。 The success of the new network area identifier is (position) update process different from the previous LAI LAI. 具体来说,对于所示实例,候选用户设备单元30检测网络区域标识符NAI26_f。 Specifically, for example, the user equipment unit 30 detects candidate network area identifier NAI26_f. 作为子步骤S-1A-2,用户设备单元30经由毫微微无线电基站28fj向无线电网络控制器节点262发送RRC连接建立消息。 As a sub-step S-1A-2, user equipment unit 30 via the femto radio base station 28fj connection setup message to the RRC 262 transmits the radio network controller node. 子步骤S-1A-2的RRC连接建立消息包括与用户设备单元30有关的标识信息,例如候选用户设备单元30的IMSI。 RRC sub-step S-1A-2 of the connection establishment message comprises identification information about the user equipment unit 30, for example, IMSI candidate user equipment unit 30. 作为子步骤S-1A-2的一部分,毫微微无线电基站28fj通过适当的接口(例如Iub接口)将RRC连接建立消息转发到无线电网络控制器262。 As part of the sub-steps of S-1A-2, the femto radio base station 28fj through an appropriate interface (e.g. Iub interface) connection establishment message to the radio network controller 262 RRC.

[0059] 在接收到子步骤S-1A-2的RRC连接建立消息时,无线电网络控制器节点262检查寻呼控制数据库46,以便查明用户设备单元30是否为毫微微无线电基站28fj的准许用户/订户/客户。 [0059] Upon receiving the sub-step RRC S-1A-2 connection setup message, the radio network controller 262 checks the paging control node database 46, the user equipment unit 30 in order to identify whether the femto radio base station permits the user to 28fj / subscriber / customer. 在这方面,子步骤S-1A-3对毫微微寻呼控制数据库46的检查/查询消息包括用户设备单元30的标识符和寻求准许的毫微微无线电基站28fj的标识符。 In this regard, the sub-step S-1A-3 femto paging control 46 checks database / query message includes an identifier and a user equipment unit identifier seek permission of the femto radio base station 30 of 28fj. 因此,在子步骤S-1A-3的上下文中,寻呼控制数据库46还可以可选地用作访问控制数据库。 Thus, in the context of sub-step S-1A-3, the paging control database 46 may also optionally be used as an access control database. 在还可以可选地作为访问控制数据库的方面,数据库存储被准许使用毫微微无线电基站进行访问的容许用户设备单元的列表。 In regard also optionally as an access control database, which stores a list of permissible user is permitted to use the equipment unit femto radio base station access. 也就是说,访问控制数据库被查询并用来确定是否对尝试使用毫微微无线电基站访问无线电接入网的候选用户设备单元提供访问权。 That is, the access control database is queried and used to determine whether to attempt to use to access the femto radio base station candidate user equipment unit in a radio access network providing access. 在当前情况下,假定候选用户设备单元30被准许或容许对/经由毫微微无线电基站28fj进行访问,因此RRC连接建立接受消息被发送,如图6的子步骤S-1A-4所示。 In the present case, assuming that the candidate user equipment unit 30 is permitted or allowed to / 28fj radio base station via the femto access, thus establishing an RRC connection accept message is sent, the sub-step shown in FIG. 6 S-1A-4 in FIG.

[0060] 鉴于已经批准了RRC连接并且通知了这种情况的事实,执行区域更新操作。 [0060] In view of the RRC connection has been approved and is notified of the fact that this case, the execution area update operation. “区域更新操作”适当地表示例如位置区域更新(LAU)或路由区域更新(RAU)。 "Area Update operation" appropriately represents e.g. Location Area Update (LAU) or Routing Area Update (RAU). 例如,如果用户设备单元连接到核心网络20的电路交换(CS)域,则位置区域更新操作被执行,如图6的子步骤S-1A-5A所示。 For example, if the user equipment unit is connected to a core network 20 of the circuit switched (CS) domain, the location area update operation is performed, as shown in sub-step S-1A-5A 6 shown in FIG. 另一方面,如果用户设备单元连接到核心网络20的分组交换(PS)域,则路由区域更新操作被执行,如图6的子步骤S-1A-5B所示。 On the other hand, if the user equipment unit is connected to the core network 20 is a packet switched (PS) domain, then the routing area update operation is performed, as shown in FIG S-1A-5B 6 sub-steps. 如图6所示,位置区域更新操作在用户设备单元30与移动交换中心(MSC)节点之间执行,路由区域更新操作在用户设备单元30与SGSN节点之间执行。 6, the operation performed between a location area update (MSC) node in the user equipment unit 30 and the mobile switching center, routing area update operation performed between the user equipment unit 30 and the SGSN node.

[0061] 通过已经对用户设备单元30执行了区域更新操作/过程,无线电接入网这时处于可寻呼用户设备单元30的位置。 [0061] Area Update has been performed by the operation / process unit 30 of the user equipment, the radio access network in case the paging position of the user equipment unit 30. 图1B和图6实际上示出,作为步骤或事件S-1B,接收到用户设备单元30的寻呼消息。 1B and FIG. 6 shows a fact, as a step or event S-1B, the user equipment receiving the paging message of unit 30. 设法寻呼作为其“目标”或“被寻呼”用户设备单元的用户设备单元30的步骤或事件S-1B的寻呼消息可从例如核心网络20始发。 Try paging the user equipment unit which, as the "target" or "Paging" user equipment units or the step S-1B paging message of event 30 may, for example, 20 originating from a core network. 寻呼消息还指定寻呼的网络区域标识符(例如LAI或RAI)、如NAI26_f。 Paging messages also specify network area identifier (e.g., LAI or RAI), as NAI26_f paging.

[0062] 在接收到步骤S-1B的寻呼消息时,无线电网络控制器节点262核对毫微微寻呼控制数据库46,以便准确地确定网络区域NAI26_f的毫微微无线电基站的哪一些将涉及寻呼,使得仅寻呼用户设备单元30有权访问的毫微微无线电基站。 [0062] Upon receiving a paging message in step S-1B, the radio network controller node 262 check femto paging control database 46, in order to accurately determine which of the femto radio base station of the network region will involve some paging NAI26_f , so that only the page the user equipment unit 30 has access to the femto radio base station. 毫微微无线电基站处理机88指令搜索器接口92准备寻呼控制数据库46的查询,使得无线电网络控制器节点262可确定区域中的哪些毫微微无线电基站有资格寻呼用户设备单元30。 Femto radio base station interface processor 88 instruct the search query 92 to prepare a paging control database 46, so that the radio network controller node 262 may determine which area of ​​the femto radio base stations are eligible to page the user equipment unit 30. 对寻呼控制数据库46的查询包括被寻呼或目标用户设备单元30的标识符和寻求寻呼准许的区域的网络区域标识符。 Paging control database query includes an identifier 46 and the search area paging network permitted paging area identifier or target user equipment unit 30.

[0063] 在上述方面,图1C和图6的步骤S-1C示出无线电网络控制器节点262检查寻呼控制数据库46并从其中获得授权或准许对用户设备单元30寻呼的网络区域NAI26_f中的毫微微无线电基站的列表。 [0063] In the above aspect, the step of FIG. 1C and FIG. 6 S-1C shows a radio network controller 262 checks the paging control node database 46 and authorized or permitted area network to the user equipment unit NAI26_f 30 wherein the paging from femto radio base station list. 在这方面,对于图4所示的寻呼控制数据库46的示例格式,返回的列表包括目标用户设备单元的MSI或其它标识符映射到的或者与其关联的那些毫微微无线电基站的标识符。 In this respect, the paging control database shown in FIG. 4 is an exemplary format 46, the returned list includes the target user equipment unit MSI or other identifier that is mapped to or in connection with the femto radio base station identifier associated.

[0064] 图1D和图6的步骤S-1D示出下一个步骤或事件,将目标用户设备单元30的寻呼消息转发到准许对用户设备单元30进行寻呼的毫微微无线电基站。 [0064] FIG. 1D and step S-1D 6 shows the next step or event, the forwarding destination user equipment unit 30 to permit the paging message for paging the user equipment unit 30 of the femto radio base station. 在图1D所示的特定情况下,为了易于说明,只有一个毫微微无线电基站被准许进行寻呼,即毫微微无线电基站28fj。 In the specific case illustrated 1D, the ease of explanation, only one femto radio base station is permitted to be paged, i.e., the femto radio base station 28fj. 但是,应当理解,在其它情况下,完全可行或可能的是,可在两个或两个以上毫微微无线电基站中寻呼用户设备单元30。 However, it should be understood that, in other cases, entirely feasible or possible, a femto radio base station can page the user equipment unit 30 in two or more. 例如,同一个毫微微拥有者/操作员可操作两个或两个以上毫微微无线电基站,并对那个毫微微拥有者/操作员拥有/操作的所有毫微微无线电基站中的用户设备单元30准予访问和寻呼合格状态。 For example, a femto same owner / operator operably two or more femto radio base station and the femtocell owner / operator has all the femto radio base station / user equipment operation unit 30 grants access and paging qualified status.

[0065] 图1E和图6的步骤S-1E示出,在毫微微无线电基站28w的小区Cw中广播对目标用户设备单元30的寻呼消息。 Step S-1E [0065] FIG. 1E and FIG. 6 shows, broadcast paging message to the target user equipment unit 30 in the femto cell radio base station Cw of 28w. 如果在其它毫微微无线电基站中已经准许对用户设备单元30的寻呼,则对用户设备单元30的寻呼消息也将在那些其它毫微微无线电基站中广播。 If other femto radio base station has been granted to the user equipment a paging unit 30, the message will be broadcast paging the user equipment unit 30 to those in the other femto radio base station.

[0066] 因此,在一种意义上,毫微微寻呼控制数据库46配置用于重新定义目标用户设备单元的有效寻呼区域。 [0066] Thus, in one sense, the femto paging control database 46 is configured to redefine the target paging area active user equipment units. 不是如步骤S-1B在寻呼消息中最初指定的寻呼区域为整个区域NAI26_f,而是由于步骤S-1C的执行,寻呼控制数据库46将寻呼区域的大小重新定义并实际上减小到只有被准许对目标用户设备单元30进行寻呼的那些小区(由寻呼控制数据库46的表或列表指定)。 Step-1B S not, as originally specified in the paging area in the paging message for the entire region NAI26_f, but because the step S-1C, the paging control the size of the paging area database 46 redefines and actually reduced It is granted only to those cells to the target user device paging unit 30 (designated by the paging control table or list of database 46).

[0067] 寻呼控制数据库46可设置为无线电接入网24的独立节点,如图1A-图1E所示,或者(备选地)位于无线电接入网的无线电网络控制器节点。 [0067] The paging control node database 46 may be provided independently of the radio access network 24, as shown in FIG. 1A- 1E, the, or (alternatively) located in the radio network controller node of a radio access network. 优选地,寻呼控制数据库配置用于响应无线电网络控制器节点的询问而进行确定(如作为上述步骤S-1C的一部分发生)。 Preferably, the paging database configured to control radio network controller in response to interrogation of the node determined (e.g., as described above in step S-1C part occurs).

[0068]用被准许使用毫微微无线电基站进行访问而进行寻呼的容许用户设备单元的识别码预先配置和/或动态配置毫微微寻呼控制数据库46。 [0068] with the femto radio base station is allowed to use the access code for allowing a user equipment unit identification paging preconfigured and / or dynamically configured femto paging control database 46. 在这方面,在RNC中以及在毫微微寻呼控制数据库46中用标识符诸如(例如)序列号等来标识毫微微无线电基站28fj。 In this regard, in the RNC and the femto paging control database 46 using an identifier such as (e.g.) a serial number to identify the femto radio base station 28fj. 最初、例如在微微/毫微微拥有者/操作员购买或获得微微基站的商店或其它销售点处进行序列号与移动用户识别码(例如MSI)之间的关联。 Initially, for example, has in the pico femto / person / operator or for later obtained at a store or other point of sale of the association between the pico station serial number with a mobile subscriber identity (e.g. MSI). 此外,还有可能的是,毫微微无线电基站28fj的毫微微/微微拥有者/操作员定义哪些移动用户(例如哪些用户设备单元(UE))能够访问毫微微无线电基站28fj。 In addition, it is also possible that the femto femto / pico owner / operator of the radio base station which mobile 28fj user-defined (e.g. which user equipment unit (the UE)) to access the femto radio base station 28fj. 例如使用基于万维网的服务可实现这种访问控制(无论是远程的、随后的和/或动态的),其中基站的拥有者首先被授权,然后能够定义容许或准许的移动用户。 For example, web services that allow such access control (whether it is remote, and subsequent / or dynamic), wherein the first base station, the owner is authorized, then the mobile subscriber can be defined based on allowing or permitting. 移动用户优选地使用MSISDN号来标识,然后,服务可将这些值映射到用户设备单元的IMSI值,供毫微微寻呼控制数据库46使用。 Preferably using the mobile subscriber MSISDN number identified, then the service can map these values ​​to the user equipment units IMSI value for the femto paging control database 46 used.

[0069] 在以上参照图1A-图1E所述的情况下,无线电网络控制器节点262具有对包括宏无线电基站和毫微微无线电基站的无线电基站的控制,其中无线电网络控制器节点262控制的无线电基站的子集包括毫微微无线电基站28fl、28f2、. . . 28fx。 [0069] In the case of the above with reference to FIG. 1A- 1E of FIG radio network controller 262 has control node comprises a macro radio base station and femto radio base station of the radio base station, wherein the radio network controller 262 controls a radio node subset of base stations comprises a femto radio base station 28fl, 28f2 ,... 28fx. 无线电网络控制器节点262还具有它的宏无线电基站的第一网络区域标识符以及毫微微无线电基站28fl、28f2、. . . 28fx的子集的不同网络区域标识符。 The radio network controller node 262 also has its macro radio base station and a first network area identifier of the femto radio base station 28fl, 28f2 ,... A different network area identifier subset of 28fx. 但是,在其它实现中,无线电网络控制器节点可专用于毫微微无线电基站(因而没有控制宏无线电基站),因此具有涉及在其排斥控制下的所有毫微微无线电基站的网络区域标识符。 However, in other implementations, the radio network controller nodes may be dedicated to femto radio base station (macro radio base station and therefore no control), thus having all the network area identifier of the femto radio base station is directed under its exclusive control.

[0070] 因此,该技术将目标用户设备单元的寻呼仅限制到希望提供那个特定用户设备单元的寻呼服务的那些毫微微无线电基站。 [0070] Thus, this technique paging the target user equipment units to be limited only desirable to provide paging service that particular user equipment unit that the femto radio base station. 例如,如果终端用户自己的宽带连接用于基站与RNC之间的传输,或者如果终端用户已经为毫微微RBS中的某种WCDMA空中能力付费,则这种专用性和排他性是极为重要的。 For example, if the end user's own broadband connection for transmission between base stations and the RNC, or if the end user has the ability to pay for a certain WCDMA air in the femto RBS, the dedicated and exclusive this is extremely important.

[0071] 因此,作为该技术的一个方面,寻呼控制数据库配置用于帮助确定在无线电网络控制器节点接收的目标用户设备单元的寻呼消息是否要转发到毫微微无线电基站。 [0071] Accordingly, as one aspect of this technique, the paging control database configured to assist in determining the target user equipment in the paging message the radio network controller node receiving unit whether to forward to the femto radio base station. 在一个实现中,寻呼控制数据库配置用于实际进行确定。 In one implementation, the paging control database configured for actual determination.

[0072] 因此,根据该技术的一个方面,尝试预占由毫微微无线电基站处理的小区的MS/UE(经由RNC/RBS或BSS)向核心网络20发起位置(和路由)区域更新。 [0072] Thus, according to one aspect of the technology, attempts to park by the femto cell radio base station processes the MS / UE 20 initiates a location (and routes) to the core network (via RNC / RBS or BSS) area update. RNC(或RBS)然后可在RRC连接建立时应用访问控制,并判定哪些MS/UE被容许预占毫微微无线电基站。 RNC (or RBS) and can be connected to application access control established RRC, and to determine which MS / UE is allowed camped femto radio base station. 当RNC(或者一些情况下是RBS)从核心网络20接收到电路交换或分组交换寻呼消息时,它可执行对寻呼控制数据库46的数据库查询,以便查明容许MS/UE使用哪些毫微微无线电基站。 When the RNC (or in some cases the RBS) received from the core network 20 to a circuit switched or packet-switched paging message, it may perform the database query paging control database 46 to identify permit MS / UE to use what femto The radio base station. 然后将寻呼仅转发到那些毫微微无线电基站。 Then paging forward only those femto radio base station. 这意味着,寻呼区域从所有毫微微无线电基站减小到只有容许特定MS/UE使用的那些毫微微无线电基站。 This means that all the paging area is reduced from the femto radio base station to the femto radio base station that allow only a specific MS / UE to use.

[0073] 上述原理/方法还可适用于与WCDMA不同的无线电技术,WCDMA仅作为一个实例来说明。 [0073] The principle / method can also be applied to different radio technologies and WCDMA, WCDMA will be described as an example only. 其它适当的技术包括但不限于GSM、CDMA、WiMAX等。 Other suitable techniques include, but are not limited to GSM, CDMA, WiMAX and the like. 该技术具体与上述和适当描述的系统及情况相关,但也可适用于其它情况以及其它网络。 The particular technique related to the above described and appropriate systems and situation, but also applicable to other cases and other networks. [0074] 作为另一个示例实现,在RNC中为它控制下的所有毫微微无线电基站分配许多(例如多个)LAI (和RAI)。 [0074] As another example implementation, all femto radio base station under its control in the RNC allocating a number (e.g., a plurality of) the LAI (and RAI). 当毫微微无线电基站连接到RNC时,自动为该毫微微无线电基站分配这些LAI之一。 When the femto radio base station connected to the RNC, one of the LAI assigned automatically for the femto radio base station. 这些LAI分配例如可通过循环方式,使得各LAI包含几乎相等数量的毫微微无线电基站。 These LAI allocated, for example by round-robin fashion, such that each of the LAI contained approximately equal numbers of femto radio base station. 这个具体实现的一个优点在于,网络中不需要其它改变。 An advantage of this particular implementation is that, no other changes in the network. 不必要的寻呼业务量也减小了,但在搜索特定UE时,仍然需要寻呼大量毫微微RBS。 Unnecessary paging traffic is also reduced, but when searching for a specific UE, a lot still needs to be paged femto RBS.

[0075] 在本文所述的技术中,寻呼区域从所有毫微微无线电基站减小到只有容许特定MS/UE使用的那些毫微微无线电基站。 [0075] In the technique described herein, all of the paging area is reduced from the femto radio base station to the femto radio base station that allow only a specific MS / UE to use. 这意味着,在毫微微无线电基站与RNC之间的回程上没有产生额外的且不必要的业务量。 This means that no extra and unnecessary traffic on the backhaul between the femto radio base station and RNC.

[0076] 在当今的WCDMA系统中,无线电资源控制(RRC)协议终止于RNC。 [0076] In today's WCDMA system, a radio resource control (RRC) protocol terminations in the RNC. RRC处理对MS/UE的寻呼。 RRC paging process to MS / UE of. 在另一个系统中,RRC或等效无线电控制协议可终止于实际的基站。 In another system, RRC, or equivalent control protocol may be terminated at the radio base station actually. 因此,在本技术的范围之内,事实是寻呼控制数据库46可驻留在其它节点,或者从其它节点进行查询。 Thus, within the scope of the present technology, the fact is that the paging control database 46 may reside in another node, or queries from other nodes. [0077] 虽然已经详细说明和描述了本发明的各种实施例,但权利要求书不限于任何具体实施例或实例。 [0077] While there has been illustrated and described in detail various embodiments of the present invention, but the claims are not limited to any particular embodiment or example. 以上描述不应当被理解为表示任何具体单元、步骤、范围或功能是绝对必要的。 The above description should not be construed as indicating any particular means, step, range, or function is absolutely necessary. 本发明不是要限制到所公开的实施例,而是意在涵盖各种修改和等效配置。 The present invention is not intended to be limited to the disclosed embodiments, but is intended to cover various modifications and equivalent arrangements.
