中继接入系统为用户数据配置数据承载通道的方法及系统 Access user data relay system configuration data bearer channel method and system

技术领域 FIELD

[0001] 本发明涉及蜂窝无线通讯领域,具体涉及一种中继接入系统中为用户数据配置数据承载通道的方法及系统。 [0001] The present invention relates to cellular radio communications, and in particular relates to a method and system for relay access system configuration data bearer path for the user data.

背景技术 Background technique

[0002] 在蜂窝无线通讯系统中,固定基站网络的无线覆盖由于各种各样的原因受到限制,比如各种建筑结构对无线信号的阻挡等原因造成在无线网络的覆盖中无可避免的存在覆盖漏洞。 [0002] In a cellular wireless communication system, the fixed wireless base station network coverage is limited due to various reasons, resulting in a variety of building structures such as wireless network coverage in the inevitable presence of radio signal blocking other reasons coverage holes. 另外一方面在小区的边缘地区,由于无线信号强度的减弱,以及相邻小区的干扰,导致UE在小区边缘时,通讯质量较差,无线传输的错误率提高。 On the other hand in the edge region of the cell, due to the reduced strength of the wireless signal, and the interference of the neighboring cells, at a cell edge leading to poor communication quality of the UE, the wireless transmission error rate is increased. 为了提高数据率的覆盖率,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LTE引入了一种无线网络节点,称为中继(relay),系统架构如图1所示。 In order to improve coverage data rates, group mobility, temporary network deployment, the cell edge throughput and coverage area of ​​a new area, the introduction of the LTE-A radio network node, known as a relay (Relay), the system architecture shown in Figure 1. 其中eNodeB是连接到核心网的固定基站,relay节点通过无线接口连接到eNodeB,为不在eNodeB覆盖范围内的UE(如图中UE2)提供接入服务。 Wherein the eNodeB is connected to the core network of fixed base stations, relay nodes are connected via a wireless interface to the eNodeB, for the UE (as shown in UE2) is not within the coverage eNodeB provide access services.

[0003] Relay可以通过多种方法中继数据,比如直接放大接收到的基站发送无线信号,或者将基站发送的数据接收后进行对应的处理,将正确接收的包再转发给终端,或者基站和中继合作向终端发送数据,相反Relay也会中继从终端向基站发送的数据。 [0003] Relay for relaying data through a variety of methods, such as direct amplification wireless base station receives a transmission signal, or perform a corresponding process when data is received by the base station, the received packet will be forwarded to the correct terminal or the base station, and relay-cooperation transmits data to the terminal, opposite relay will relay data transmitted from the terminal to the base station.

[0004] 在众多的中继类型中,有一种中继被称为类型一中继(Type I relay),其特点如下: [0004] In many types of relay, there is a type called a relay is a relay (Type I relay), which is characterized as follows:

[0005] (I)对UE来说是一个独立的小区; [0005] (I) for the UE is a separate cell;

[0006] (2) Relay小区有物理小区标识、同步信道等参数; [0006] (2) Relay cell physical cell identification, synchronization channels and other parameters;

[0007] (3) UE和Relay之间的无线传输调度由Relay完成; [0007] (3) between the wireless transmission scheduling performed by the UE and Relay Relay;

[0008] (4) LTE 的UE 可以接入Relay ; [0008] (4) LTE UE may access Relay;

[0009] (5) Relay节点可以为LTE-A的UE提供增强功能。 [0009] (5) Relay node may provide enhanced functionality for the UE LTE-A.

[0010] 满足以上功能的Relay接入系统的系统架构如图2所示。 [0010] The system architecture satisfies the above functions Relay access system shown in Figure 2. 其中EPC为核心网,包含MME (移动管理实体)、Serving GW(服务网关,简称SGW)和TON GW(分组数据网络网关,简称PGW)。 Wherein the core network EPC, comprising MME (Mobility Management Entity), Serving GW (Serving Gateway, referred SGW) and TON GW (Packet Data Network Gateway, referred PGW). Relay连接的eNodeB称为DeNB (Donor eNodeB,载体演进型节点B) ;Relay对应的SGW/PGW是Relay节点以UE身份接入网络时对应的服务网关和分组数据网络网关;OMCServer是为Relay节点提供管理功能的网络管理服务器。 Relay is referred to as an eNodeB connected DeNB (Donor eNodeB, evolved Node B carrier); Relay corresponding SGW / PGW Relay node is an access network when the UE identity corresponding to a serving gateway and a packet data network gateway; OMCServer Relay Node is to provide network management server management functions. 在具体实现时Relay对应的SGW/PGW和DeNB可以在同一个在物理实体上,后面流程描述就采用二者物理实体合一的结构。 In specific implementation Relay corresponding SGW / PGW and a DeNB can be on the same physical entity, the process described later on the use of both physical entity structure unity. Relay和UE之间的接口继承eNodeB和UE间的Uu接口功能,Relay节点和DeNB间的接口定义为Un接口。 Relay interface between the UE and the inheritance Uu interface function between the eNodeB and the UE, the interface defined between the Relay Node and is DeNB Un interface.

[0011] Un接口也是无线接口,为了减少对设备的改动,3GPP会议确定对Relay架构的评估条件之一是减少对现有设备的改动,因此Un接口底层承载沿用Uu接口承载,如图3所 [0011] Un interface is a wireless interface, in order to reduce changes to the equipment, 3GPP meeting determined to evaluate the condition of one Relay architecture is to reduce the change to the existing equipment, so the Un interface Uu interface inherit underlying bearer carrier, Figure 3

/Jn ο / Jn ο

[0012] 目前由于MAC(Medium Acces Control,介质访问控制)数据头对应的逻辑信道个数有限,Un接口的数据DRB (无线承载)个数最大为11个。 [0012] Since the current MAC (Medium Acces Control, media access control) header data of a finite number of logical channels corresponding to the number of DRB Un interface data (radio bearer) up to 11. 对于Uu接口,一个UE建立的无线承载个数很少,完全能满足要求;但是对于Un接口,Relay需要支持多个UE,如果每个UE的承载都对应Un接口的一个DRB,Un接口的DRB个数远大于11。 For the Uu interface, the number of radio bearer established by the UE a few can meet the requirements; however, for the Un interface, Relay UE needs to support multiple, DRB if a bearer for each UE corresponds to the Un interface, DRB Un interface The number is far greater than 11. 因此,如果不改动MAC协议,必须把多个UE的承载按照某种规则分发到Un接口的DRB上。 Thus, if the MAC protocol does not change, the carrier must be distributed to the plurality of UE DRB Un interface according to certain rules.

[0013]目前存在一种分发方式是根据用户数据(IP数据)中的的IP数据头中的一个字段把每个用户数据分发到Un接口的DRB上。 [0013] Currently there is a distribution mode according to a field of the user data (IP) in an IP header in the user data onto each of the distribution DRB Un interface. 具体实施方式是: DETAILED DESCRIPTION is:

[0016] 如果该UE当前是从Relay节点接入的: [0016] If the UE is currently accessible from Relay node:

[0017] (3) a.PDN GW根据所述承载上下文对应的QOS为IP数据设置服务类型,QOS和服务类型的映射关系为预前配置好;并且把服务类型填写到承载层IP数据的TOS(服务类型,Type of service)字段也被称为DS (区分服务)字段; [0017] (3) a.PDN GW according to the QOS of the bearer context corresponding to a pre-configured IP data before the service type, service type, and QOS mapping relationship; fill service and the type of data to the carrier layer of the IP TOS (service type, type of service) field is also referred to as DS (Differentiated services) field;

[0018] (4) a.PDN Gff使用数据承载通道把IP数据发送到DeNB,DeNB根据IP数据的TOS字段或者说DS字段找到对应的Un接口承载并通过该承载把数据发送给Relay节点。 [0018] (4) a.PDN Gff transmits data using IP data bearer channel to the DeNB, DeNB Un interface finds the corresponding bearer and sends the data to a Relay node through the IP bearer according to the TOS field of the data or the DS field. TOS字段或者说DS字段的取值可能对应一个或者多个Un接口承载。 The value of the DS field or TOS field may correspond to one or more of the Un interface bearers.

[0021] (4)b.服务网关使用对应的数据承载通道把用户数据发送到DeNB,DeNB根据IP数据的TOS字段或者说DS字段找到对应的Un接口承载并通过该承载把数据发送给Relay节点。 [0021] (4) b.

[0024] 如果UE不是从Relay接入的,分组数据网络网关和服务网关只需要根据IP地址和QOS找到分组数据网络连接以及对应的承载上下文进行数据转发即可,不需要进行QOS映射以及填写TOS字段。 [0024] If the UE is not, the packet data network gateway and a serving gateway only needs to find the packet data network connection and corresponding bearer Relay access from the IP address and QOS context data forwarding is not required QOS mapping and fill TOS field. 所以执行上述过程中第三步之前,TON Gff ((3)a)或者服务网关((3)b)需要判断哪些UE当前从Relay节点接入。 Therefore, the above-described process performed before the third step, TON Gff ((3) a), or serving gateway ((3) b) from which the UE currently accesses Relay node requires determination. 否则必须对每个IP数据包都做QOS映射并根据服务类型找到对应的数据承载通道,增加了不必要的处理,降低了数据传输速率和网元的处理能力。 Otherwise, must be mapped to each QOS do IP packet data bearer and to find the corresponding channel, it adds unnecessary processing reduces the data transfer rate and processing capabilities in accordance with the NE service type.

[0068] 在现有技术中,为了协商UE和分组数据网络网关间应用层参数,3GPP定义了PCO(Protocol configuration options,协议配置选项)参数,此参数可以是UE填写并通过非接入层消息发送给核心网,也可以由核心网发送给UE。 [0068] In the prior art, for the application layer parameters negotiated between the UE and the packet data network gateway, 3GPP defines the PCO (Protocol configuration options, Protocol Configuration Options) parameter that can be filled by UE NAS message to the core network can also be sent by the core network to the UE. PCO可配置的协议类型包括一些标准的网络通信协议,也可以是3GPP定义的专门用于移动通信业务使用的特殊参数。 PCO configuration protocol type may include certain standard network communication protocols, and may be designed for specific parameters used in the mobile communication service defined by 3GPP. 上述特殊参数不一定是对应某个协议,而可能只是在UE和网络之间发送特殊请求和配置参数,比如UE向网络发送的PCO可能包含P-CSCF Address Request (代理呼叫会话控制功能实体地址请求)和DNS Server Address Request (域名服务器地址请求)等请求,网络向UE发送的PCO可能包含P-CSCF Address和DNS Server Address等配置参数。 The above parameters are not necessarily corresponding to a particular protocol, but may just send a special request and configuration parameters between the UE and the network, such as the PCO UE transmits to the network may include P-CSCF Address Request (proxy call session control function entity address request ) and DNS server address request (domain name server address request) requesting the like, PCO network sends to the UE may contain P-CSCF address DNS server address and other configuration parameters.

[0069] 根据PCO定义,可以考虑UE把当前是否通过Relay节点接入的指示信息包含在PCO参数中发送给TON GW。 [0069] The PCO defined, it can be considered currently by the UE Relay node indication information comprises the access to a TON GW in PCO parameter. 具体地,可以对PCO参数的附加参数列表增加以下定义: In particular, the following definitions may be added to the list of additional parameters PCO parameters:

[0070] 用户到网络方向:是否通过Relay节点接入标识。 [0070] user to network direction: if the access identifier by the Relay Node.

[0071] 本实施例是在初始接入过程中,UE获得其是否从Relay接入的彳目息后,将该/[目息填写在PCO参数中,并将包含PCO参数的PDN连接建立请求消息通过Relay发送给核心网,核心网通过该PCO参数获知所述UE是否从Relay接入,在接收到发送给该UE的下行IP数据后,仅对从Relay接入的UE的IP数据进行QOS与服务类型的映射。 [0071] In this embodiment, during the initial access procedure, whether the UE is obtained from the left foot of the access destination information Relay, the / [fill in the PCO mesh parameter information, and the parameters contained PCO PDN connection establishment request message to the core network through the Relay, the core network parameter PCO know whether the UE, after receiving the IP data sent to a downlink of the UE, only the QOS for IP data of the UE from the access from the Relay Relay access and service type mappings. UE发起PDN连接建立的过程如图4所示,包括: UE initiates a PDN connection establishment procedure shown in Figure 4, comprising:

[0074] PDN连接建立请求消息中包含承载标识、请求类型、PDN类型、APN (接入点名称)、PCO (协议配置选项等参数)。 [0074] PDN connection establishment request message includes a bearer identifier, the request type, the PDN type, the APN (Access Point Name), the PCO (protocol configuration options, etc. parameters). 其中PCO参数中包含“是否通过Relay节点接入标识”字段。 Wherein the parameter includes PCO "is identified by the access node Relay" field.

[0075] 在填写PCO中的标识字段时,可采取以下方式之一: [0075] When completing the identification field in the PCO, you can take one of the following ways:

[0076] 若UE通过Relay接入,则将该字段置为有效,若不是通过Relay接入,则将该字段置为无效; [0076] If the UE through the access Relay, then the field is set to active, if not through Relay access, then the field is deasserted;

[0077] 若UE通过Relay接入,则将该字段置为有效,若不是通过Relay接入,则将该字段置为空;[0078] 若UE通过Relay接入,则将该字段置为空,若不是通过Relay接入,则将该字段置为有效。 [0077] If the UE through the access Relay, then the field is set to active, if not through Relay access, then the field is set to null; [0078] If the UE through the access Relay, then the field is set to null , if the access is through Relay, then the field is set to valid.

[0079] UE获取当前是否通过Relay节点接入的方法可以是读取系统广播或者Relay通过RRC连接建立过程获取,具体地,Relay可通过RRC连接建立消息(RRC Connection Setup)通知UE,但不限于上述方法。 [0079] The method Relay UE currently acquired by the access node can be read by system broadcast or RRC connection procedure to establish Relay obtain, in particular, may notify the UE Relay connection setup message (RRC Connection Setup) by RRC, but not limited to the method described above.
