[0002] 在蜂窝无线通信系统中,一方面,固定基站网络的无线覆盖由于各种各样的原因存在一定局限性,例如,各种建筑结构对无线信号的阻挡等原因造成无线网络覆盖中不可避免的存在覆盖漏洞;另一方面,在小区边缘地区,由于无线信号强度的减弱,以及相邻小区的干扰,导致用户设备(UE,User Equipment)在小区边缘时,通信质量较差,无线传输的错误率大大提高。 [0002] In cellular radio communication system, on the one hand, fixed wireless network coverage of base station due to various reasons there are some limitations, for example, various building structures resulting wireless network coverage is not available on other radio signal causes the barrier at the cell edge, poor hand, in the cell edge area, since the weakening of the wireless signal strength, and interference of the neighboring cells, resulting in a user equipment (UE, user equipment) communication quality, wireless transmission; coverage holes to avoid the presence of the error rate is greatly increased. 为了提高数据传输的正确率、群组移动性、临时网络部署、小区边缘地区的吞吐量以及新区域的覆盖,在增强型长期演进(LTE,Long Term Evolution)系统中引入了一种无线网络节点,称为中继(relay)节点,其架构如图1所示,其中,基站(eNodeB)是连接到核心网的固定基站,中继节点通过无线接口连接到eNodeB,为不在eNodeB覆盖范围内的UE、如图1中的UE2提供接入服务。 In order to improve the accuracy of data transmission, group mobility, temporary network deployment, the cell edge throughput and coverage area of ​​a new area, the introduction of a radio network node in a Long Term Evolution Advanced (LTE, Long Term Evolution) system , called a relay (relay) node, its structure shown in Figure 1, wherein the base station (eNodeB) is connected to the core network of fixed base stations, relay node is connected to the eNodeB via a radio interface, not within the coverage eNodeB UE, in FIG 1 UE2 provide access services.

[0003] 中继节点可以通过多种方式对基站向UE发送的数据进行中继,例如,直接放大来自基站的数据的无线信号;或接收基站发送的数据后进行对应处理,将正确接收的数据再转发给UE;或基站与中继节点协同合作向UE发送数据。 Or data corresponding to the processed data received from the base station, the correctly received; [0003] The relay node may be performed by a variety of ways to a base station relaying the data sent by the UE, e.g., direct amplification of a radio signal from the base station of the data forwarding to the UE; or a base station and relay node to transmit data to the UE synergistic cooperation. 相应地,中继节点也会对UE向基站发送的数据进行中继。 Accordingly, the UE will relay node relaying the data transmitted from the base station.

[0004] 在众多的中继类型中,有一种中继被成为类型一中继(Type I relay),其特点如下:对UE来说是一个独立的小区;中继节点的小区有物理小区标识、同步信道等参数;UE 与中继节点之间的无线传输调度由中继节点来完成;LTE的UE可以接入中继节点;中继节点可以为LTE-A的UE提供增强功能。 [0004] In many types of relay, there is a type known as a relay repeater (Type I relay), which is characterized as follows: the UE is in a separate cell; cell relay node has a physical cell identity , a synchronization channel and other parameters; scheduled wireless transmission between the UE and the relay node is accomplished by the relay node; the LTE UE may access the relay node; relay node may provide enhanced functionality for the UE LTE-a.

[0005] 满足以上功能的中继节点接入增强型LTE系统时,其位置如图2所示。 When [0005] LTE-relay node access system satisfies the above functions, the position shown in FIG. 其中,EPC 为核心网,包含移动管理实体(MME,Mobility Management Entity)、服务网关(Serving Gff)和分组数据网网关(PDN GW)。 Wherein, the EPC core network, comprising a mobile management entity (MME, Mobility Management Entity), a serving gateway (Serving Gff) and a packet data network gateway (PDN GW). 中继节点连接的eNodeB称为载体eNodeB (DeNB,Donor eNodeB),操作维护中心月艮务器(0MC Server, Operations&Maintenance Center Server)是对中继节点具有管理功能的网络管理服务器、即网管服务器。 The relay node is connected is referred to as eNodeB support eNodeB (DeNB, Donor eNodeB), operation and maintenance center device that works to months (0MC Server, Operations & Maintenance Center Server) is a network management server having the management function of the relay node, i.e., network management server. 中继节点与UE之间的接口继承eNodeB与UE之间的Uu接口功能,中继节点与DeNB之间的接口定义为Un接口。 An interface between the relay node and the UE functionality inheriting Uu interface between the eNodeB and the UE, the interface between the relay node and the definition of DeNB Un interface.

[0006] 为了使中继节点能够为UE提供服务,中继节点自身必须先接入到无线网络中,建立Un接口连接,其中一种方式就是中继节点与UE —样,通过UE建立业务的方式、即分组数据网(PDN,Packet Data Network)连接激活过程接入到无线网络,具体处理如图3所示,其中,MME是为中继节点接入提供服务的MME节点,S-GW/P-GW (Relay)是为中继节点接入提供服务的服务网关和分组数据网网关。 [0006] In order to provide for the relay node to serve the UE, a relay node itself must access the radio network, to establish Un interface connection, wherein the relay node is one way and UE - like, by the UE to establish business manner, i.e. a packet data network (PDN, packet data network) connection activation procedure to access the wireless network, specifically the processing shown in FIG. 3, wherein, MME is the MME node serving as a relay node access, S-GW / P-GW (relay) is a serving gateway and a packet data network gateway serving the relay node access.

[0013] 每一个APN可以对应多个无线接入承载,其中有一个缺省承载和多个专用承载。 [0013] Each APN may correspond to a plurality of radio access bearer, which has a plurality of default bearer and dedicated bearer. 所述NAS消息是与无线接入承载类型有关的NAS消息,可以为对应缺省无线接入承载的激活缺省EPS 承载上下文请求(ACTIVATE DEFAULT EPSBEARER CONTEXT REQUEST),也可以为对应专用无线接入承载的激活专用EPS承载上下文请求(ACTIVATE DEDICATED EPS BEARER CONTEXTREQUEST),目的是通知中继节点对应无线接入承载的非接入层参数,如EPS承载标识、协商的QoS参数、PCO参数等。 The NAS message is related to radio access bearer type NAS message, the bearer context request (ACTIVATE DEFAULT EPSBEARER CONTEXT REQUEST) corresponding ACTIVATE DEFAULT EPS default radio access bearer may be dedicated to a corresponding radio access bearer dedicated EPS bearer context activation request (aCTIVATE dEDICATED EPS bEARER CONTEXTREQUEST), notifies the relay node object corresponding to the non-access layer parameters of the radio access bearer, the EPS bearer QoS parameters such as identification, negotiation, the PCO parameters.

[0014] 步骤308 :DeNB收到初始上下文建立请求后,根据MME提供的承载信息向中继节点发起承载建立请求,并且将与无线接入承载类型有关的NAS消息发送给中继节点。 [0014] Step 308: DeNB after receiving the initial context setup request, MME initiates a bearer according to the bearer information provided to the relay node setup request, and the radio access bearer related NAS type message to the relay node. 中继节点收到承载建立请求后,与DeNB建立无线接入承载。 The relay node after receiving the bearer establishment request to establish the radio access bearer and the DeNB.

[0015] 步骤309 :无线接入承载建立完成后,DeNB向MME发送初始上下文建立响应。 [0015] Step 309: After establishing a radio access bearer is completed, DeNB transmits an initial context setup response to the MME.

[0016] 步骤310 :中继节点处理完与无线接入承载类型有关的NAS消息后,通过RRC信令将与无线接入承载类型有关的NAS响应消息发送给DeNB。 [0016] Step 310: The relay node associated with the NAS message type radio access bearer processed by RRC signaling related to the type of radio access bearer response message to the NAS DeNB. 与无线接入承载类型有关的NAS响应消息可以为对应缺省无线接入承载的激活缺省EPS承载上下文接受(ACTIVATE DEFAULT EPS BEARER CONTEXT ACCEPT)消息,也可以为对应专用无线接入承载的激活专用EPS 承载上下文接受(ACTIVATE DEDICATED EPS BEARER CONTEXT ACCEPT)消息。 Activation associated with specific types of radio access bearer response message may carry the NAS context accept (ACTIVATE DEFAULT EPS BEARER CONTEXT ACCEPT) message to the corresponding radio access ACTIVATE DEFAULT EPS default bearer may be dedicated bearer corresponding to the radio access EPS bearer context accept (ACTIVATE DEDICATED EPS bEARER cONTEXT ACCEPT) message.

[0017] 步骤311 =DeNB将与无线接入承载类型有关的NAS响应消息转发给MME。 [0017] Step 311 = DeNB associated with the radio access bearer type NAS response message to the MME.

[0018] 通过上述中继节点接入过程,中继节点会获得一个动态分配的IP地址,并建立一个或者多个PDN连接,包括Un接口的无线接入承载,这样,图2中,中继节点就可以作为IP 设备与EPC和OMC服务器进行通信,具体方法是:中继节点与EPC之间交互的信令、以及中继节点和OMC服务器之间传输的数据均作为上述PDN连接的用户层IP数据。 [0018] access procedure via the relay node, the relay node will receive a dynamically assigned IP address, and establishing one or more PDN connections, including the Un interface radio access bearer, so that, in FIG. 2, the relay node may communicate with the EPC as an IP device and OMC server, the specific method is: the signaling interaction between the relay node and the EPC, and data transfer between the relay node and the server are OMC as a user layer of the PDN connection IP data.

[0019] 在现有无线网络中,网元与网管服务器之间的通信基本是基于IP的,预先为网元配置用来管理该网元的网管服务器的IP地址,然后网元根据IP地址向对应的IP设备请求配置数据或发送网络运行数据。 [0019] In existing wireless networks, communication between the NE and the NMS server is IP-based basic, pre-configured IP address for managing the network element NE of the network management server, and the IP address to the NE corresponding IP transmitting device requests the network configuration data or performance data. 对于中继节点而言,其接入地点以及接入的DeNB都是动态可变的,因此,无法在网络规划初期就确定管理中继节点的对应网管服务器的IP地址,但是目前还没有中继节点动态获取网管服务器的IP地址的实现方案。 For relay node, its location and access DeNB access are dynamically variable, therefore, unable to determine the corresponding network management server's IP address management relay node in the network early stages of planning, but there is no relay implementation of network management server node dynamically obtain IP addresses.
