Background technique '
现有有线通信网络技术如 PSTN/ISDN具有通信环境良好、 有线带宽资 源丰富、 通信质量较高、 通信和控制技术较无线移动简单、 安全可靠等优 势, 但与无线移动通信技术相比, 有线通信技术固定静止不可移动、 专用 不可共享的特性制约了其进一步和快速发展, 使得有线通信技术的上述优 势难以充分利用和发挥, 并且固定、 静止、 专用的特点以及现有的有线固 定通信技术无需也无法实现定位技术。 无线移动通信技术虽然也有其固有 的、 无法回避和难以克服的不足和问题, 如无线频率资源的匮乏和昂贵、 安全保密性差、 通信环境恶劣、 通信质量较差、 需要大功率射频技术以及 无线移动通信和控制技术日益复杂等, 但由于具有无线和可移动特性, 为 用户的通信带来了极大的灵活和方便, 无线移动特性和用户设备及固定唯 一的号码可随身携带使用的特点使得用户及用户设备的位置需要经常性地 确定, 由此而产生了无线移动通信位置业务(LCS )及技术, 同时借助无 线定位技术还可以优化无线通信***的性能和优化无线资源管理, 但由于 无线通信环境恶劣、 用户及用户设备的位置随意、 不确定性, 其定位技术 相当复杂, 不仅定位技术的种类非常繁多如基于小区 ID的定位、 基于无线 传输技术 RTT的定位、 基于到达时间 TOA或到达时间差 TDOA的定位、 基于到达角度 AOA的定位、 基于参考节点 ROTP的定位、 基于 GPS的定 位等, 以及还需要基于网络、 基于移动终端、 基于网络且移动终端辅助、 基于移动终端且网络辅助等繁多的定位方式, 并需要进行大量、 复杂的测 量计算, 而且如果用户移动速度较快加上定位处理的时延较大, 极易造成 定位处理的结果虽然非常精确但仍产生严重定位误差的问题。 发明内容
有线非连续移动通信技术的出现使得有线通信技术的许多优势得以充 分发挥利用, 同时有线非连续移动的特性、 用户设备及固定唯一的号码也 可随身携带使用的特点同样需要对用户及用户设备的位置进行准确定位, 加上有线接入的特性使得基于有线非连续移动通信网络的筒单、 精确的定 位技术成为可能。 The existing wired communication network technologies such as PSTN/ISDN have the advantages of good communication environment, rich wired bandwidth resources, high communication quality, simple communication and control technology compared to wireless mobile, and are safe and reliable, but compared with wireless mobile communication technologies, wired communication The fixed fixed, non-removable, and non-shareable features of technology constrain its further and rapid development, making the above advantages of wired communication technology difficult to fully utilize and play, and the fixed, static, dedicated features and existing wired fixed communication technologies do not need to be Unable to implement positioning technology. Wireless mobile communication technology also has its inherent, unavoidable and insurmountable deficiencies and problems, such as lack of radio frequency resources and expensive, poor security and confidentiality, poor communication environment, poor communication quality, high-power RF technology and wireless mobile Communication and control technologies are becoming more and more complex, but because of their wireless and mobile features, they bring great flexibility and convenience to users' communication. The characteristics of wireless mobile features and user equipment and fixed unique numbers can be carried around. And the location of the user equipment needs to be determined frequently, thereby generating wireless mobile communication location service (LCS) and technology, and at the same time, by wireless positioning technology, the performance of the wireless communication system can be optimized and the wireless resource management can be optimized, but due to wireless communication The environment is harsh, the location of users and user equipment is arbitrary and uncertain, and its positioning technology is quite complicated. Not only the types of positioning technologies are very diverse, such as cell ID-based positioning, radio transmission technology based RTT positioning, arrival time TOA or arrival time difference. TDOA , location based on angle of arrival AOA, location based on reference node ROTP, location based on GPS, etc., and also requires a variety of positioning methods based on network, mobile terminal based, network based and mobile terminal assisted, mobile terminal based and network assisted, A large number of complex measurement calculations are required, and if the user moves faster and the delay of the positioning process is large, the result of the positioning process is very likely to be very accurate, but still causes serious positioning error. Summary of the invention The emergence of wired discontinuous mobile communication technology has enabled many advantages of wired communication technology to be fully utilized. At the same time, the characteristics of wired discontinuous mobility, user equipment and fixed unique numbers can also be carried around, and the same needs for users and user equipment.

本发明的目的是提供一种基于有线非连续移动通信网络的定位方法, 从而使得能在有线非连续移动通信网络中实现精确的位置业务。 It is an object of the present invention to provide a positioning method based on a wired discontinuous mobile communication network, thereby enabling accurate location services in a wired discontinuous mobile communication network.
本发明的另一目的是提供一种基于有线非连续移动通信网络的定位系 统, 以实现有线非连续移动通信中的定位功能。 Another object of the present invention is to provide a positioning system based on a wired discontinuous mobile communication network to implement a positioning function in wired discontinuous mobile communication.
为了达到上 明目的, 本发明基于有线非连续移动通信网络的定位系 统包括: 用户设备定位功能模块、 接入网定位功能模块以及位置业务网关 中心。 三个部分相互配合、 并与有线非连续移动通信网络的用户设备、 有 线接入网以及核心网相互协同操作, 以共同完成基于有线非连续移动通信 网络的定位。 定位的类型包括用户自己发起请求的位置业务和网络或笫三 方发起请求的位置业务。 定位***中的用户设备是具有有线非连续移动通 信功能的用户设备, 接入网为支持有线非连续移动的有线接入网、 核心网 为具有有线非连续移动通信功能的核心网。 In order to achieve the above objective, the positioning system based on the wired discontinuous mobile communication network of the present invention comprises: a user equipment positioning function module, an access network positioning function module, and a location service gateway center. The three parts cooperate with each other and with the user equipment of the wired discontinuous mobile communication network, the wired access network and the core network to jointly perform the positioning based on the wired discontinuous mobile communication network. The type of location includes the location service that the user initiates the request and the location service that the network or the third party initiates the request. The user equipment in the positioning system is a user equipment with wired discontinuous mobile communication function, the access network is a wired access network supporting wired discontinuous mobility, and the core network is a core network having wired discontinuous mobile communication function.
由于有线非连续移动通信的特性及有线接入网中的接入设备在安装开通 后其位置是基本固定不变的, 因此本发明定位方法无须象无线移动通信定 位技术那样进行大量复杂的实时、 动态、 频繁、 精确测量和计算, 只要在 接入网设备工程安装完成后事先对用户端接入设备及其接入端口的位置定 位信息数据进行人工勘测, 或者在用户端接入设备中安装 GPS接收器自动 进行位置定位勘测, 然后将位置信息数据存储记录于接入网定位功能模块 和位置业务网关中心, 由于有线接入的特点, 用户设备一且接入其位置就 随接入网的用户端接入设备及其接入端口的位置而确定了, 即使使用了短 距无线技术替代用户设备与用户端接入设备之间的有线连接, 用户设备的 活动范围也是限定在接入网用户端接入设备及其接入端口位置附近的几 米、 几十米最多百米内, 因此本发明方法只需要基于网络的定位方式就可 以实现位置业务。 而且参照传统的 PSTN通信网络的做法, 即使需要变换 地点、 重新移机安装用户端接入设备时, 用户应先向运营商申报后方可由 局方工程人员实施移机工作, 在这种情况下就需要重新勘测用户端接入设 备及其接入端口新的位置定位信息数据, 并及时更新接入网定位功能模块
和位置业务网关中心中的相关定位信息数据。 通过用户设备及通信网络的 相互配合, 本发明定位技术可以通过电路域或分组域的多种接入方式如消 息类接入、 语音类接入、 客户端应用程序类接入、 Web类接入等进行呼叫 / 会话相关型定位、 呼叫 /会话无关型定位、 运营管理型定位等以实现位置业 务, 如用户设备请求查询自己的位置业务, 网络查询紧急呼叫的主叫用户 设备的位置业务, 位置业务客户端发起查询用户设备的位置业务等。 Since the characteristics of the wired discontinuous mobile communication and the access device in the wired access network are substantially fixed after the installation is opened, the positioning method of the present invention does not need to perform a large amount of complex real-time like the wireless mobile communication positioning technology. Dynamic, frequent, accurate measurement and calculation, as long as the location location information data of the user access device and its access port is manually surveyed after the installation of the access network device is completed, or the GPS is installed in the user access device. The receiver automatically performs a position location survey, and then records the location information data in the access network location function module and the location service gateway center. Due to the characteristics of the wired access, the user equipment accesses the location along with the user of the access network. The location of the access device and its access port is determined. Even if short-range wireless technology is used instead of the wired connection between the user equipment and the user access device, the activity range of the user equipment is limited to the access network user end. Within a few meters, tens of meters, and up to 100 meters near the location of the access device and its access port, The method of the present invention only needs a network-based positioning method to implement location services. Moreover, referring to the practice of the traditional PSTN communication network, even if it is necessary to change the location and re-transfer the installation of the client access device, the user should first report to the operator before the transfer work can be performed by the local engineering personnel, in this case It is necessary to re-survey the new location location information data of the client access device and its access port, and update the access network location function module in time. And related positioning information data in the location service gateway center. Through the cooperation of the user equipment and the communication network, the positioning technology of the present invention can access multiple access modes in the circuit domain or the packet domain, such as message type access, voice type access, client application type access, and Web type access. Waiting for call/session-related positioning, call/session-independent positioning, operation management-type positioning, etc. to implement location services, such as user equipment requesting to query its own location service, network querying the location service of the calling user equipment of the emergency call, location The service client initiates querying the location service of the user equipment.
采用本发明基于有线非连续移动通信网絡的定位方法和***, 为用户 提供了一种新颖的、 精确的定位技术, 改变了现有有线通信技术因固定、 静止、 专用的不足而无法和无需实现位置业务的现状; 同时, 由于本发明 定位技术基于有线非连续移动通信, 因此非常简便、 低成本, 避免了现有 无线移动通信定位技术十分复杂和不准确问题。 附图说明 The positioning method and system based on the wired discontinuous mobile communication network of the invention provide a novel and accurate positioning technology for the user, which changes the existing wired communication technology due to the fixed, static and special deficiencies and cannot and does not need to be realized. At present, the positioning technology of the present invention is based on wired discontinuous mobile communication, so it is very simple and low-cost, and avoids the problem that the existing wireless mobile communication positioning technology is very complicated and inaccurate.
