Description

一种长期演进技术的后续演进系统中的定位方法 The method of locating subsequent evolution of the LTE system in the

技术领域 FIELD

[0001] 本发明涉及移动通信技术,特别是涉及一种长期演进技术的后续演进(LTE-A)系统中的定位方法。 [0001] The present invention relates to mobile communication technologies, particularly to a method for locating the subsequent evolution of a long-term evolution (LTE-A) system.

背景技术 Background technique

[0002] 定位技术是根据测量无线信号来判决用户设备(UE)地理位置和速率的方法。 [0002] positioning technology is a method of measuring the radio signal according to the decision the user equipment (UE) location and rate. 图1为长期演进(LTE)系统演进的通用移动通信系统无线接入网(E-UTRAN)中UE定位结构示意图。 1 is a schematic structural diagram of FIG positioned long term evolution (LTE) system evolved universal mobile telecommunications system radio access network (E-UTRAN) in the UE. 如图1所示,增强的服务移动位置中心(E-SMLC)用于管理支持目标UE的不同位置服务,包括:UE的定位、发送辅助数据给UE。 1, the enhanced service mobile location center (E-SMLC) for managing the different positions the target UE support the service, comprising: positioning the UE, auxiliary data is transmitted to the UE. E-SMLC可以通过移动性管理实体(MME)与服务基站(eNB)交互,从eNB获得UE的定位测量,包括eNB执行的上行测量和UE执行的下行测量,上述定位测量作为其它功能的一部分被提供给eNB,例如切换功能等。 E-SMLC can be obtained by a mobility management entity (MME) and a serving base station (eNB) interaction from the eNB positioning measurements of the UE, including the downlink measurement uplink measurements and the UE performs the eNB performs, said positioning measurements as another part of the functions are provided to the eNB, for example, the switching functions. E-SMLC也可以通过MME及eNB与目标UE交互,当某个位置服务发出请求时传递辅助数据,或者获得位置估计。 E-SMLC may pass through the MME and eNB UE interact with the target when a location service request assistance data, or obtains the position estimate.

[0003] 在现有的LTE公开协议9 (LTE Release-9)中,存在两个关于LTE系统定位的协议,分别为:LTE定位协议(LPP)和LTE定位协议附加(LPPa)。 [0003] In the existing LTE protocols Publication 9 (LTE Release-9), there are two positioning agreement on the LTE system, respectively: LTE Positioning Protocol (LPP) and additional LTE Positioning Protocol (LPPa). 其中,LPP协议终止在UE和E-SMLC之间,LPPa协议终止在eNB和E-SMLC之间。 Wherein, LPP protocol terminated between the UE and the E-SMLC, LPPa protocol terminated between the eNB and the E-SMLC. 在LTE Release-9公开的LTE系统中的定位方法中,定位过程开始后,根据LPPa协议由E-SMLC启动服务eNB查找UE位置过程,和/或,根据LPP协议由E-SMLC启动UE的查找位置过程。 Positioning method in LTE Release-9 disclosed LTE system, a positioning operation starts, according LPPa protocol initiated by the E-SMLC serving eNB lookup UE location process, and / or, in accordance with LPP protocol initiated by the E-SMLC UE lookup location process.

[0004] 在LTE技术之后,第三代合作伙伴计划(3GPP)继续对LTE方案进行增强,LTE公开协议10(LTE Release-10)中提出了LTE-A系统。 [0004] After LTE technology, the Third Generation Partnership Project (3GPP) LTE to continue to enhance the program, proposed LTE-A system LTE-disclosure agreement 10 (LTE Release-10). LTE-A系统在接入网的架构中增加了中继节点(Relay Node,RN),该节点可以看作是eNB的延伸,为系统提供更经济的覆盖。 LTE-A system adds a relay node (Relay Node, RN) in the access network architecture, the node can be seen as an extension of the eNB, to provide a more economical system coverage. RN与eNB通过无线接口连接,它可以在eNB覆盖的边缘增强覆盖质量,也可以在eNB覆盖区域之外部署来扩展覆盖的范围。 RN connecting with the eNB via a wireless interface, it can cover the edge enhancement eNB coverage quality, can be deployed to extend coverage range eNB outside the coverage area. 图2为现有的LTE-A系统架构示意图。 FIG 2 is a conventional LTE-A system architecture diagram. 如图2所示,为RN提供无线接入服务的eNB被称为施主基站(Donor eNB, DeNB), RN与DeNB之间通过无线的Un接口连接;RN与UE之间通过无线的Uu接口连接;RN与核心网的移动性管理实体与服务网关(MME/S-GW)节点通过SI接口连接,该SI接口经过DeNB转接,即DeNB作为RN与MME/S-GW之间的SI接口的转发节点。 As shown, the RN to eNB providing wireless access service is referred to as a donor base station 2 (Donor eNB, DeNB), Un interface between the RN and the DeNB via a wireless; through a wireless interface Uu between the RN and UE ; RN and the core network and the mobility management entity serving gateway (MME / S-GW) through the node interface SI, the SI DeNB transfer through the interface, i.e., as a DeNB SI between the RN and the MME / S-GW interface forwarding node. 在LTE-A架构中,DeNB可以接受UE的接入,也可接受RN的接入。 In LTE-A architecture, the DeNB can accept access of the UE, the RN also accept access. 当DeNB接受UE的接入时,该DeNB表现为一个普通的eNB。 When receiving DeNB access of the UE, the performance of a DeNB ordinary eNB. 当DeNB接受RN的接入时,该DeNB包含中转功能,具体表现为:S1应用部分(SlAP)信令和用户平面数据都先到达DeNB,DeNB获得到达的信令和数据,可以对它们进行解析甚至修改,然后再转发给RN或演进的分组核心网(EPC)。 When receiving the access DeNB the RN, the relay function comprises a DeNB, specific performance CFA is: S1 Application Part (SLAP) signaling and user plane data are the first to reach DeNB, signaling and data obtained DeNB arrival, they may parse even modify, and then forwarded to RN or evolved packet core (EPC).

[0005] 在目前现有的LTE Release-10技术中,尚未针对LTE-A架构下的定位过程提出有效地实现方法。 [0005] In the current LTE Release-10 of the conventional art, no effective method for positioning procedure implemented in LTE-A architecture. 因为LTE-A架构中增加了RN节点,因此如果仍旧采用LTE Release-9中的定位方法,当某个节点发起定位过程后,RN无法参与定位过程,则通过RN进行接入的UE无法成功的完成定位过程。 Because the LTE-A node RN adds architecture, so if still using the positioning method of LTE Release-9, when a node initiates a positioning procedure, RN can not participate in the positioning process, the access is performed by the UE can not successfully RN complete the positioning process. 总之,现有的LTE-A架构相关技术中的定位方法无法成功地实现定位过程。 In short, positioning method existing LTE-A architecture related art can not be successfully positioning process. 发明内容 SUMMARY
