技术领域 FIELD

[0007] 本发明通常涉及通信系统,并且更具体地,涉及无线通信系统。 [0007] The present invention relates generally to communication systems, and more particularly, to wireless communication systems. 背景技术 Background technique

[0008] 传统的无线通信系统使用基站网络向一个或多个移动单元提供无线连通性。 [0008] Conventional wireless communication systems use a network of base stations to provide wireless connectivity to one or more mobile units. 在一些情况下,移动单元可以发起与网络中的一个或多个基站的无线通信,例如,当移动单元的用户想要发起语音或数据呼叫时。 In some cases, the mobile units may initiate wireless communication with one or more network base stations, e.g., the mobile unit when the user wants to initiate a voice or data call. 可替换地,网络可以发起与移动单元的无线通信链路。 Alternatively, the network may initiate the wireless communication link with the mobile unit. 例如,在传统的分级无线通信中,服务器将送往目标移动单元的语音和/或数据传送到中心单元,例如基站控制器(BSC)。 For example, in conventional hierarchical wireless communications, the server will be sent to the target mobile unit voice and / or data to the central unit, for example, a base station controller (BSC). 然后,BSC可以经由一个或多个基站收发信台或BTS将寻呼消息传送到目标移动单元。 Then, BSC transmits a paging message to the target mobile unit via one or more base transceiver stations, or BTS. 响应于从无线通信系统接收到寻呼,目标移动单元可以建立到一个或多个基站收发信台的无线链路。 In response to receiving the paging from a wireless communication system, the target mobile unit may establish a wireless link to one or more base transceiver stations. BSC中的无线电资源管理功能接收语音和/或数据并协调该组基站收发信台所使用的无线电和时间资源以将信息传送到目标移动单元。 The BSC receives the voice radio resource management functionality and / or data and coordinates the radio and time resources of the set of base transceiver stations are used to transmit information to the target mobile unit. 无线电资源管理功能可以执行更细致的控制以分配和释放用于在一组基站收发信台上广播传输的资源。 Radio resource management function can perform more detailed control to allocate and release resources for a group of base transceiver stage broadcast transmission.

[0009] 传统的基站在被称为小区、宏蜂窝和/或扇区的地理区域内提供无线连通性。 [0009] Traditional base stations provide wireless connectivity within a geographic area macrocells and / or sectors is referred to as a cell. 传统的基站收发信台能够使用预定数量的可用传输功率来传送信号。 Traditional base transceiver stations can be used a predetermined number of available transmit power to transmit a signal. 宏蜂窝的范围由多种因素来确定,所述多种因素包括可用的传输功率、可用功率的角分布、宏蜂窝内的障碍物、环境条件等。 Range of the macrocell is determined by many factors, the angle of a variety of factors including the transmission power available, the distribution of the available power, obstructions within the macrocell environmental conditions. 例如,宏蜂窝的范围可以从人口稠密的城市环境中的少至300米变化到人口稀少的乡村环境中的多至10公里。 For example, the macrocell can range from densely populated urban environment to change as little as 300 m up to 10 km sparsely populated rural environment. 如果这些参数中的任意一个改变,覆盖范围同样可以及时改变。 If any of these parameters change a coverage can also change in time.

[0010] 传统的分级网络结构的一种替换是分布式结构,所述分布式结构包括接入点的网络,例如基站路由器,其实现分布式通信网络功能。 [0010] An alternative to the conventional hierarchical network architecture is a distributed architecture, the distributed architecture including a network of access points, such as base station routers, that implement distributed communication network functionality. 例如,每个基站路由器可以将无线电网络控制器(RNC)和/或PDSN功能结合到单个实体中,所述单个实体管理一个或多个移动单元和外部网络(例如,因特网)之间的无线电链路。 The radio link between, for example, each base station router may be incorporated Radio Network Controller (RNC) and / or PDSN functions in a single entity, a single entity to one or more mobile units and an external network (e.g., Internet) road. 基站路由器完全地封装蜂窝接入技术并且可以代理使用支持等价IP功能的核心网单元的功能。 Base station routers completely encapsulate the cellular access technology and may proxy functionality using the core network element support to equivalent IP functions. 例如,可以通过移动IP家乡代理(HA)和GGSN锚定功能来提供UMTS基站路由器中的IP锚定(anchoring),其中基站路由器通过等价的移动IP信令进行代理。 For example, by the Mobile IP Home Agent (HA) and the GGSN anchoring functions to provide a UMTS base station router IP anchor (anchoring), wherein the base station through the proxy router equivalent Mobile IP signaling. 与分级网络相比,分布式结构具有降低部署网络的成本和/或复杂度、以及降低添加附加无线接入点(例如,基站路由器)的成本和/或复杂度的潜力,从而扩大现有网络的覆盖范围。 Compared to hierarchical networks, distributed network deployment configuration having a reduced cost and / or complexity, and cost reduction potential and adding additional wireless access points (e.g., base station routers) and / or complexity, thereby expanding the existing network coverage. 由于在分级网络的独立RNC和PDSN实体处的分组排队延迟可以降低或移除,分布式网络还可以降低(与分级网络相比)用户所体验的延迟。 Since the packet queuing delays separate RNC and PDSN entities in hierarchical networks may be at a reduced or removed, the distributed network may also be reduced (as compared to hierarchical networks) the delays experienced by the user.

[0011] 至少部分因为降低了部署基站路由器的成本和复杂性,基站路由器可以部署在对于传统基站来说是不切实际的位置。 [0011] at least in part because of the reduced cost and complexity of deploying a base station router, base station routers may be deployed in the traditional location of the base station is impractical. 例如,基站路由器可以部署在住宅或建筑物中,从而为建筑物居所的居住者提供无线连通性。 For example, base station routers may be deployed in a residence or building to provide wireless connectivity to the occupants of a building residence. 部署在住宅中的基站路由器典型地被称为家庭基站路由器或毫微微蜂窝基站(femtocell),这是由于它们旨在为围绕住宅的非常小的区域(例如,毫微微蜂窝基站)提供无线连通性。 Base station routers deployed in a residence are typically referred to as home base station routers or femtocells (Femtocell), since they are intended for the very small area around the house (e.g., femtocell base stations) provide wireless connectivity . 毫微微基站具有比传统基站小得多的功率输出,传统基站用于为宏蜂窝(macrocell)提供覆盖。 The femto base station power output than conventional base stations much smaller, for providing coverage for a conventional macrocell base station (macrocell). 例如,典型的毫微微蜂窝基站具有IOmV 级的传输功率。 For example, a typical femtocell has a transmission power level IOmV. 因此,典型的毫微微蜂窝基站的范围比宏蜂窝的范围要小得多。 Thus, a typical range of a femtocell is much smaller than the range of a macrocell. 例如,毫微微蜂窝基站的典型范围大约是100米。 For example, a typical range of a femtocell is about 100 m. 还可以部署毫微微蜂窝基站集群以提供对更大区域和/或更多用户的覆盖。 It can also be deployed femtocell cluster to provide coverage to a larger area and / or more users.

[0012] 在覆盖配置中,期待结合宏蜂窝网络来部署毫微微蜂窝基站。 [0012] in the overlay configuration, the expected macro-cellular network deployed in conjunction with the femtocell. 例如,宏蜂窝网络可以用于为包括多个住宅的邻域提供无线连通性。 For example, a macro-cellular network may be used to provide wireless connectivity to include a plurality of residential neighborhoods. 从邻域经过或位于多个住宅之一中的任何移动单元可以使用宏蜂窝网络来接入无线通信系统。 After the neighborhood or located in any one of the plurality of mobile units in a house from a macro-cellular network may be used to access the wireless communication system. 单独的毫微微蜂窝基站可以部署在一个或多个住宅中以提供住宅内(或附近)的覆盖范围。 Individual femtocells can be deployed in a residence or more to provide (or near) the residence coverage. 还可以将毫微微蜂窝基站的集群部署在一个或多个建筑物中以提供建筑物内(或附近)的覆盖范围。 Also femtocell cluster can be deployed in one or more of the building to provide a building (or near) the coverage. 在每种情况中,覆盖区域内的宏蜂窝和毫微微蜂窝基站间会有一对多的关系。 In each case, in the region covering the macro and the femto cell base station will be the relationship between many. 然而典型地,移动单元将仅被授权驻扎在所选择的毫微微蜂窝基站上。 Typically, however, the mobile unit will only be authorized to camp on the selected femto cell base station. 例如,由单独用户所操作的移动单元可以被授权驻扎在所述用户在他们的住宅中安装的毫微微蜂窝基站上。 For example, mobile unit operated by the individual user can be authorized to camp on the femtocell installed by the user in their residence. 另一个实例中,由雇员所操作的移动单元可以被授权驻扎在由企业所安装的毫微微蜂窝基站集群中的毫微微蜂窝基站上。 In another example, mobile units operated by the employee can be authorized to camp on femtocells in a femtocell cluster installed by a business.

[0013] 在许多情况下,部分现有的宏蜂窝网络已经工作了一段时间并且因此可能是使用前代无线接入技术来实现的。 [0013] In many cases, some of the existing macro cellular network has been working for some time and may therefore be used before generation radio access technology to achieve. 因此,相对来说近来安装的毫微微蜂窝基站可能使用比现有宏蜂窝更为近代的无线接入技术。 Thus, the relatively recently installed femtocells may use a radio access technology than the existing macrocells more modern. 例如,无线通信系统可能包括第二代宏蜂窝和第三代毫微微蜂窝基站。 For example, the wireless communication system may include second-generation macrocells and third generation femtocells. 当用户在由宏蜂窝和毫微微蜂窝基站所服务的地理区域移动通过时,可能需要无线接入技术间(RAT间)的切换以在第二代QG)宏蜂窝和第三代(3G)毫微微蜂窝基站之间切换移动单元。 When the user moves from a geographical area macrocell and femtocell base station served by, you may need to switch the radio access technology (RAT room) to the second generation QG) macrocells and the third generation (3G) mM handover of a mobile unit between the picocell base station. 传统的通信系统使用无线电条件和/或无线电资源的可用性来确定何时执行无线接入技术间的切换。 Conventional communication systems use radio conditions and availability / or radio resources to determine when to switch between radio access technologies implemented. 例如,可以使用移动单元和宏蜂窝和/或毫微微蜂窝基站之间传送的信号来测量信道质量和/或信号强度。 For example, a signal transmitted between the mobile unit and the macrocells and / or the femtocell base station to measure the channel quality and / or signal strength. 当宏蜂窝所传送的信号的信道质量和/或信号强度相对于毫微微蜂窝基站的测量的信道质量和/或信号强度来说较差时,传统的系统将移动单元从宏蜂窝切换到毫微微蜂窝基站。 When the channel quality of the transmitted signals of the macro and / or poor signal strength relative to the measured channel quality and / or signal strength of the femtocell base station, the conventional mobile system unit switches from the macrocell to the femtocell cellular base stations.

[0014] 然而,传统的RAT间切换标准在通用毫微微蜂窝基站、与特定移动单元相关联的毫微微蜂窝基站和宏蜂窝之间不作区分。 [0014] However, the conventional inter-RAT handover to the femtocell in a standard general, between the femtocell specific mobile unit associated with the macrocell and does not distinguish. 所以,只要宏蜂窝网络中的无线电条件具有充分高的质量,移动单元可能不切换到授权的家庭和/或企业毫微微蜂窝基站,即使用户处于相关毫微微蜂窝基站所覆盖的家庭或企业中。 Therefore, as long as the radio conditions in the macro-cellular network having a sufficiently high quality, the mobile unit may not switch to authorized home and / or business femtocells, femtocells associated home or business covered even if the user is in. 例如,宏蜂窝网络中的无线电条件可能保持充分高的质量以实质上阻止所有到毫微微蜂窝基站的RAT间切换,例如当毫微微蜂窝基站部署在宏蜂窝覆盖区域的中心时。 For example, radio conditions in the macro-cellular network may remain sufficiently high quality to prevent substantially all inter-RAT handover to the femtocell, e.g., when the femtocell base station deployments in the center of a macrocell coverage area.

[0033] 基站控制器220维持上下文数据库235,其存储与移动单元210、以及由宏蜂窝服务的其它用户设备和/或移动单元相关联的上下文信息,其中宏蜂窝连接到基站控制器220。 [0033] The base station controller 220 maintains a context database 235, which stores the context information of the mobile unit 210, and other user equipment from the macrocell and services and / or associated with the mobile unit, wherein the base station controller 220 is connected to the macrocell. 在举例说明的实施方式中,基站控制器220将与移动单元210相关的信息和指示移动单元210与首要毫微微蜂窝基站相关联的信息存储在用于移动单元210的上下文235中。 In the illustrated embodiment, the base station controller 220 stores the information associated with the mobile unit 210 and information indicating the mobile unit 210 and the premier femtocell base station associated with the context 235 for the mobile unit 210. 例如,用于移动单元210的上下文235可以包括标识符、指示首要毫微微蜂窝基站可用的布尔变量、指示首要毫微微蜂窝基站205所使用的频率的参数、以及毫微微蜂窝基站205的位置。 For example, the context 210 for the mobile unit 235 may include an identifier, a Boolean variable indicating the first femtocell is available, a parameter indicating the frequency of the first femtocell 205 is used, and the position of the femtocell 205. 一旦配置了移动单元210的上下文235,基站控制器220知道移动单元210与首要毫微微蜂窝基站相关联。 Once the mobile unit's configuration context 235 210, the base station controller 220 knows that the mobile unit 210 and the premier femtocell associated base station. 尽管已将移动单元210描述为与单个首要毫微微蜂窝基站相关联,但是受益于本公开内容的本领域普通技术人员应当了解,在替代的实施方式中,移动单元210 可以与多于一个的首要毫微微蜂窝基站相关联。 Although the mobile unit 210 has been described as a single premier femtocell associated base station, those of ordinary skill having the benefit of this disclosure should be understood that in an alternative embodiment, the mobile unit 210 may be associated with more than one primary femtocell associated.

[0034] 在举例说明的实施方式中,最初是由基站215在包括上行链路240和下行链路245 的无线通信链路上为移动单元210提供服务,其中上行链路240和下行链路245是根据第二组标准和/或协议建立的。 [0034] In the illustrated embodiment, is initially served by base station 215 on the uplink 240 comprises a downlink 245 and a wireless communication link 210 to the mobile unit, wherein the uplink 240 and downlink 245 It is established in accordance with a second set of standards and / or protocols. 移动单元210还会知道到它的位置。 To the mobile unit 210 will know its location. 在举例说明的实施方式中,移动单元210包括使用GPS卫星网络沈0 (在图2中仅示出一个)所提供的信号255来确定其位置的全球定位系统(GPQ功能250。可替换地,移动单元210可以使用基站收发信台215在下行链路245上所提供的信息来了解其位置。这种方法可以称为辅助GPS技术。 移动单元210因此可以使用所存储的首要毫微微蜂窝基站205的位置来确定首要毫微微蜂窝基站205离移动单元210有多远。 In the illustrated embodiment, the mobile unit 210 includes a network of GPS satellites using Shen 0 (in FIG. 2 only one shown) 255 signal provided by a global positioning system to determine its position (GPQ function 250. Alternatively, the mobile unit 210 may use information in the base transceiver station 215 on a downlink 245 to provide for location. this method can be referred to as assisted GPS technology. Thus the mobile unit 210 may use the stored first femtocell 205 determining a position of the premier femtocell base station 205 from the mobile unit 210 how far.

[0035] 基站控制器220可以配置移动单元210以用于基于事件的触发。 [0035] The base station controller 220 can configure the mobile unit 210 based on the trigger event. 在一个实施方式中,基站控制器220可以定义基于位置的RAT间事件,其可以用于触发从基站收发信台215 到首要毫微微蜂窝基站205的RAT间的切换。 In one embodiment, the base station controller 220 may define location-based inter-RAT event, which may be used to trigger the inter-RAT handover 205 from the base transceiver station 215 to the premier femtocell base station. 例如,移动单元210可以配置为,当首要毫微微蜂窝基站205和移动单元210之间的距离降至小于配置的阈值距离时,传送包括基于位置的RAT间事件的消息。 For example, the mobile unit 210 may be configured to, when the first femtocell 205 and the mobile unit 210 to less than the distance between the configured threshold distance, transmits a message including the location-based inter-RAT event. 可以按各种方式中的任意一种来配置阈值距离,所述各种方式包括预配置阈值距离、阈值距离的用户配置(例如,基于首要毫微微蜂窝基站205所服务的建筑物的大小)等。 It may be in any of a variety of ways to configure a threshold distance, a variety of ways including pre-configured threshold distance, the user configures a threshold distance (e.g., based on the size of the building premier femtocell base station 205 service), etc. . [0036] 基站控制器220还可以使用其它信息,例如信道条件(如果它们可用的话),来确定是否执行移动单元210到毫微微蜂窝基站205的RAT间的切换。 [0036] The base station controller 220 may also use other information, such as channel conditions (if they are available) to determine whether the inter-RAT handover the mobile unit 210 to the femtocell 205 is performed. 例如,如果无线接入技术实现用于在RAT间切换中的目标接入技术上执行信道条件测量的技术,那么可以测量信道条件以及响应于基站控制器220所提供的请求将测量的信道条件的值报告给基站控制器220。 For example, if the wireless access technology for inter-RAT handover target access technology in the implementation of channel condition measurement technique, the channel conditions may be measured and in response to channel conditions to a base station request controller 220 is provided to measure value to the base station controller 220. 例如,在基于位置的RAT间切换事件的实例中,当基站控制器220从移动单元210 接收RAT间事件消息时,基站控制器220可以指示移动单元210来执行和报告信道条件测量。 For example, examples of the switching between the event based on the position of the RAT, the base station controller 220 when the inter-RAT event message received from the mobile unit 210, the base station controller 220 may instruct the mobile unit 210 to perform and report the measured channel conditions. 在UMTS技术中使用的技术的一个实例是压缩模式技术,其允许移动单元在特定时间间隔内执行信道条件或信号强度质量测量。 One example technique used in UMTS technologies is a compressed mode technique that allows mobile units to perform channel condition or signal strength quality measurements within a specific time interval. 然而,其它无线接入技术(例如2G CDMA)可能不实施用于在RAT间切换的目标接入技术上执行信道条件或信号强度质量测量的技术。 However, other radio access technology (e.g. 2G CDMA) may not be implemented for the inter-RAT handover target access technology performing channel condition or signal strength quality measurements techniques. 例如,一些无线接入技术实现用于RAT间切换的盲切换。 For example, some radio access technologies implement blind inter-RAT handover for switching.

However, the mobile unit will continue its position its primary position femtocell compared and system implementation techniques, allowing inter-RAT signal strength quality measurements to monitor the quality of the air interface to the signal strength associated with the femtocell.

[0039] 移动单元确定(在33¾移动单元和首要毫微微蜂窝基站之间的距离已经下降低于阈值。例如,移动单元可以将其当前位置与移动单元存储器中存储的首要毫微微蜂窝基站的位置相比较(在33¾以确定距离: Position of [0039] the mobile unit determines (33¾ a distance between the mobile unit and the premier femtocell base station has dropped below a threshold. For example, the mobile unit may be a current location of the mobile unit stored in the memory of the first femtocell comparing (33¾ to determine the distance:

[0040] UE_PremireFemto_di stance = UE_coordinates-premierFemto_coordinates [0040] UE_PremireFemto_di stance = UE_coordinates-premierFemto_coordinates

[0041] 然后,可以将这个距离与阈值相比较以及当满足下列条件时可以触发切换过程: [0041] Then, this distance may be compared with a threshold value and when the following conditions may trigger the handover procedure:

[0042] UE_PremierFemto_distance < MacroToFemtoDistanceThreshold [0042] UE_PremierFemto_distance <MacroToFemtoDistanceThreshold

[0043] 当满足距离标准时,移动单元发送(在340)基于事件的测量报告,其包括指示用于系统间切换的基于位置的事件已经发生的信息。 [0043] When the distance criterion is satisfied, the mobile unit sends (at 340) event-based measurement report, which includes information indicating a location-based event has occurred in the inter-system handover. 在一个实施方式中,基站控制器(BSC) 使用在基于事件的测量报告中包括的基于位置的事件来触发(在360)移动单元从宏蜂窝到毫微微蜂窝基站的RAT间切换。 In one embodiment, the base station controller (BSC) for use in location-based inter-RAT event based measurement reporting events included to trigger (at 360) the mobile unit from the femtocell to the macrocell handover. 例如,基站控制器(BSC)可以发送(在36¾请求以发起到移动单元的RAT间切换。移动单元于是可以执行(在370)从宏蜂窝到首要毫微微蜂窝基站的RAT间切换。[0044] 如此处所讨论的,不同的无线接入技术可能支持或不支持RAT间信号强度质量测量。如果图3中描述的切换中涉及的无线接入技术支持RAT间信道或信号强度质量测量, 那么使用这些测量所收集的信息可以用于决定是否执行(在370)从宏蜂窝到首要毫微微蜂窝基站的RAT间切换。方法300于是可以包括框343中描述的附加步骤。在举例说明的实施方式中,通过传输指示移动单元应当执行移动单元和首要毫微微蜂窝基站之间的信号强度质量测量的消息,宏蜂窝对基于事件的测量报告进行应答(在34¾。允许移动单元执行RAT间信号强度质量测量的一个示例性技术是UTMS系统实现的压缩模式。然而,其它技术也可以 For example, a base station controller (BSC) can send (at 36¾ a request to initiate the inter-RAT handover of a mobile unit The mobile unit can then perform (at 370) the inter-RAT handover from the macrocell to the premier femtocell base station. [0044] As discussed herein, different radio access technologies may or may not support inter-RAT signal strength quality measurements. radio access technology to support inter-RAT channel quality or signal strength measurements if the handover depicted in Figure 3 involved, the use of these the measurement information collected can be used to decide whether to perform (at 370) the inter-RAT handover from the macrocell to the premier femtocell base station. the method 300 may then include additional steps described in block 343. in the embodiment illustrated in the embodiment, by transmitting a message indicating that the mobile unit should perform signal strength quality between the mobile unit and the premier femtocell base station measures the macrocell for measurement reporting event based response (at 34¾. permit execution strength quality between the mobile unit measured signal RAT one exemplary technique is implemented in the compressed mode UTMS system. However, other techniques may also be 于支持移动单元和首要毫微微蜂窝基站之间的信号强度质量的测量。 To support the measuring signal strength quality between the mobile unit and the premier femtocell base station.

[0045] 当移动单元接收该消息时,移动单元测量(在350)信号强度质量,例如,使用毫微微蜂窝基站所传送的导频信道。 [0045] When the mobile unit receives this message, the mobile unit measures (at 350) the signal strength quality, e.g., using the femtocell transmitted pilot channel. 然后,可以将指示测量的信号强度质量的信息报告(在355)给基站控制器。 Then, the report may be information indicating measured signal strength quality (355) to the base station controller. 可以周期性地或基于具体配置事件来报告RAT间的测量。 It may be periodically or on particular events to report a measurement configuration inter RAT. 如果移动单元周期性地报告(在35¾RAT间的测量结果,当移动单元和毫微微蜂窝基站之间信道的信号强度质量足够高以支持空中接口上的通信,假设基于距离的标准仍然满足(即,UE_ PremierFemto_distance < MacroToFemtoDistanceThreshold),那么基站控制器(BSC)可以使用测量报告中包括的信息来触发(在360)移动单元从宏蜂窝到毫微微蜂窝基站的RAT 间切换。如果移动单元传送基于事件的RAT间测量报告,那么移动单元可以决定移动单元和毫微微蜂窝基站之间信道的信号强度质量何时足够高以支持无线接口上的通信。在各种可替换的实施方式中,测量报告还可以包括其它移动性信息,包括但不限于,主扰码、定时和/或偏移信息、信号强度质量的测量等。 If the mobile unit periodically reports (measurement result between 35¾RAT, when the mobile unit and the signal strength quality between the femto base station channel is sufficiently high to support communication over the air interface, based on the assumption still meet the standard distance (i.e. UE_ PremierFemto_distance <MacroToFemtoDistanceThreshold), then the base station controller (BSC) can use the information included in the measurement reports to trigger (inter-RAT handover 360) the mobile unit from the femtocell to the macrocell if the mobile unit transmits an event based RAT inter-measurement report, the mobile unit may decide to move the femto cell and the signal strength quality of the channel between the cellular base stations when sufficiently high to support communication over the radio interface. in various alternative embodiments, the measurement report may also include other mobility information including, but not limited to, primary scrambling codes, timing and / or offset information, signal strength quality measurements.
