Description

一种无线接入承载的传输方法和系统技术领域[0001] 本发明涉及无线通信中的业务承载技术,尤其涉及一种无线接入承载的传输方法和系统。 TECHNICAL FIELD The transmission method and a radio access bearer [0001] The present invention relates to a wireless service carrier communication technique, particularly to a method and system for transmitting a radio access bearer. 背景技术[0002] 蜂窝无线通信系统如图1所示,主要由终端(UE,User Equipment)、接入网和核心网组成,基站(eNB)、或基站和基站控制器组成的网络称为无线接入网(RAN,Radio Access Network),负责接入层事务,例如无线资源的管理;核心网负责非接入层事务,例如位置更新等;UE是指可以与蜂窝无线通信网络通信的各种设备,例如移动电话、笔记本电脑等。 [0002] cellular wireless communication system shown in Figure 1, mainly by the terminal (UE, User Equipment), composed of an access network and a core network, a base station (the eNB), a base station controller or a base station and a wireless network of called access network (RAN, radio access network), is responsible for access layer transactions such as radio resource management; the core network is responsible for non-access layer transactions, such as location update, etc.; the UE refers to various cellular networks can communicate with the radio communication devices such as mobile phones, notebook computers. eNB之间可以根据实际情况存在物理或者逻辑上的连接,且每个eNB可以与一个或者一个以上的核心网节点(CN, Core Network)连接。 There may be a logical or physical connection between the eNB according to the actual situation, and each eNB may be connected to one or more than one core network node (CN, Core Network). [0003] 在蜂窝无线通信系统中,固定eNB网络的无线覆盖由于各种原因受到限制,例如各种建筑结构对于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。 [0003] In cellular radio communication systems, fixed wireless network eNB coverage is limited due to various reasons, resulting in a variety of building structures, for example, wireless network coverage in the coverage hole exists inevitable wireless signal to cause blocking. 另外,在小区的边缘地带,由于无线信号强度的减弱,以及相邻小区的干扰,导致UE在小区边缘时通信质量较差,无线传输的错误率较高。 Further, the edge of the cell, since the weakening of the wireless signal strength, and interference from adjacent cells, leading to cell edge UE is poor when the communication quality of the wireless transmission error rate is high. 为了提高数据的覆盖率、群组移动性、临时网络部署、小区边缘地带的吞吐量以及新区域的覆盖,现有技术引入了中继(Relay)的概念。 In order to improve the coverage data, coverage group mobility, temporary network deployment, the cell throughput and the edge of the new region, introduced the concept of the prior art relay (Relay) is. [0004] Relay是指具有在网络节点之间通过无线链路中继数据功能的站点,也称中继节点(Relay Node)或中继站(Relay Station),中继网络的结构如图2所示,其中,eNB直接服务的UE称为宏(Macro) UE, Relay服务的UE称为Relay UE ;eNB与UE之间的无线链路称为直传链路(direct link),包含上/下行(DL/UL, downlink/uplink)直传链路;Relay与UE之间的无线链路称为接入链路(access link),包含DL/UL接入链路;eNB与Relay之间的无线链路称为回程链路(backhaul link),包含DL/UL回程链路。 [0004] Relay means having a site between the network nodes via a relay radio link data function, also known as a relay node (Relay Node) or a relay station (Relay Station), relay network structure shown in Figure 2, wherein, UE directly served called a macro eNB (macro) UE, UE Relay Relay service called UE; wireless link between the eNB and the UE is called direct link (direct link), comprising uplink / downlink (DL / UL, downlink / uplink) direct link; a radio link between the Relay and the UE is called an access link (access link), containing DL / UL access link; a radio link between the eNB and Relay It referred to as a backhaul link (backhaul link), containing DL / UL backhaul link. [0005] Relay可以通过多种方法中继数据,例如直接放大接收到的无线信号;或者将接收的数据进行处理,再将正确接收的数据转发给UE ;或者Relay和eNB合作向UE发送数据。 [0005] Relay for relaying data through a variety of methods, for example, directly amplifies the received radio signal; or processing the received data, then forwards the data to the correctly received the UE; or a Relay eNB and cooperate to transmit data to the UE. 反之' Relay也能中继由UE向eNB发送的数据。 Conversely 'Relay relay data can be transmitted to the eNB by the UE. [0006] 在众多的中继类型中,存在一种中继被称为类型一中继(Type I Relay),其特点如下:[0007] UE无法区分中继和固定eNB下的小区,即在UE看来,Relay本身就是一个小区, 与固定eNB下的小区没有区别,此类小区可以称为中继小区。 [0006] In many relay type, there is a type called a relay is a relay (Type I Relay), which is characterized as follows: [0007] UE can not distinguish between the cell relay and the eNB fixed, i.e. UE opinion, relay itself is a cell, a cell with no difference in fixing the eNB, such cells can be referred to as a cell relay. 中继小区有自身的小区物理标识(PCI,Physical Cell Identity),与普通小区一样发送广播,当UE驻留在中继小区中时,中继小区可以单独分配无线资源给UE使用。 Relay cell has its own physical cell identity (PCI, Physical Cell Identity), the same as ordinary broadcast cell transmission, when the UE resides in the cell relay, the relay cell may allocate radio resources to the UE used alone. 中继小区和Relay UE之间的接口以及协议栈,与普通eNB小区和UE之间的相同。 The interface between the UE and the relay cell and Relay protocol stacks, the same between the normal cell and the UE and eNB.

[0060] 需要指出的是,该合并后的QCI仅在Un接口分配空口资源时有效,合并后的QCI 并不需要以显式方式或者隐式方式在Relay与DeNB之间传递。 [0060] It is noted that, QCI on the combined effective only when allocating air interface resources Un interface, QCI combined does not need to be explicitly or implicitly passed between the Relay and DeNB. [0061] Relay与DeNB之间的空中接口需要建立底层数据承载(无线承载),无线承载所要承载的内容是Relay上不同的UE业务承载(UE-E-RAB),这些不同的UE-E-RAB需要在相同的Un 口无线承载中传递。 [0061] Relay air interface between the underlying data and the DeNB need to establish bearer (radio bearer), the contents of the radio bearer is to be carried on different Relay UE traffic bearer (UE-E-RAB), these different UE-E- RAB is transmitted in the same radio bearer Un interface. [0062] 无线承载的建立是根据该合并后的QCI建立或者重配置合适的无线资源,以保证最终能满足合并QCI所指示的QoS。 [0062] The radio bearer setup or reconfiguration is suitable wireless resources to meet the QoS guaranteed ultimately combined according QCI QCI indicated on the combined. [0063] 无线承载建立完成后,DeNB将底层数据承载标识与UE-E-RAB标识的对应关系显式或者隐式的传递给Relay,这样建立或者重配置并承载与此QCI匹配的不同的UE-E-RAB, Un接口承载建立。 After the [0063] radio bearer setup complete, DeNB corresponding relationship between the underlying data bearing identification and UE-E-RAB identified explicitly or implicitly transmitted to Relay, so that the establishment or reconfiguration and carries this QCI match different UE -E-RAB, Un interfaces bearer establishment. [0064] 步骤802,UE业务承载的接受方根据预先配置的底层数据承载标识与UE业务承载标识的对应关系,从底层数据承载上获取与底层数据承载标识相对应的UE业务承载。 [0064] Step 802, the recipient UE bearer service bearer correspondence between the identifier and a UE identifier of the bearer service based on the underlying preconfigured data, data acquired from the base carrying the underlying data corresponding to the identification UE bearer service bearer. [0065] UE业务承载的接受方还能够根据该底层数据承载标识选择返回UE业务承载所使用的底层数据承载。 [0065] Recipient UE bearer service bearer identifier can also choose to return to the underlying data bearer service bearer used by UE based on the underlying data. [0066] 需要指出的是,本发明所指的底层数据承载可以是Un接口的无线承载(UnRB),也可以是中继的无线接入承载(Relay-E-RAB)。 [0066] It should be noted that the present invention refers to the underlying data carrier may be a radio bearer Un interface (UnRB), it may be a relay radio access bearer (Relay-E-RAB). [0067] 下面以Un RB为例对上述的无线接入承载的传输方法进一步说明。 [0067] In the following an example of the above-described Un RB radio access bearer transmission method described further. [0068] 在该实施例一中,某DeNB需要将两个UE不同的EPS·承载通过Relay与DeNB之间的Un接口传递到UE,如图9所示,在DeNB中的Sl-U接口存在两条UEl的无线接入承载分别是UE1E-RAB1和UE1E-RAB2 ;在DeNB中的Sl-U接口存在两条到UE2的无线接入承载分别是UE2E-RAB1 和UE2E-RAB2。 [0068] In one embodiment of this embodiment, a DeNB require two different UE EPS · Un bearer transmitted through Relay interface between the UE and the DeNB, as shown in FIG, Sl-U interface to 9 in the presence of the DeNB UEl two radio access bearers are UE1E-RAB1 and UE1E-RAB2; Sl-U interface exists DeNB two radio access bearer to UE2 are UE2E-RAB1 and UE2E-RAB2. [0069] 在Relay与DeNB之间的空口上,存在两条Relay到UEl的空中接口承载,分别为UEl Relay Uu bear I 和UEl Relay Uu bear2 ;在Relay 与DeNB 之间的空口上,存在两条Relay 到UE2 的空中接口承载,分别为UE2 Relay Uu bearl 和UE2 Relay Uu bear2。 [0069] On the air interface between the Relay and the DeNB, there are two Relay UEL air interface to carry, respectively UEl Relay Uu bear I and to UEl Relay Uu bear2; on the Relay and the air interface between the DeNB, there are two UE2 to Relay bearer air interface, respectively UE2 Relay Uu bearl and UE2 Relay Uu bear2. [0070] E-RAB与Uu bear是--映射,此处的映射关系是:[0071] UEl E-RABl 映射到UEl Relay Uu bearl,[0072] UEl E-RAB2 映射到UEl Relay Uu bear2,[0073] UE2 E-RABl 映射到UE2 Relay Uu bearl,[0074] UE2 E-RAB2 映射到UE2 Relay Uu bear2。 [0070] E-RAB and Uu bear is - mapping, mapping relationship here is: [0071] UEl E-RABl mapped to UEl Relay Uu bearl, [0072] UEl E-RAB2 mapped to UEl Relay Uu bear2, [ 0073] UE2 E-RABl mapped to UE2 Relay Uu bearl, [0074] UE2 E-RAB2 mapped to UE2 Relay Uu bear2. [0075]其中 UEl E-RABKUEI E_RAB2、UE2 E-RABKUE2 E-RABl 需要通过Relay 与DeNB 的Un接口的无线承载(Un RB)传递到Relay,并由Relay按该映射关系分别映射为UEl Relay Uu bearl、UEl Relay Uu bear2、UE2 Relay Uu bearl、UE2 Relay Uu bear2。 [0075] wherein UEl E-RABKUEI E_RAB2, UE2 E-RABKUE2 E-RABl radio bearer needs to be passed through the Un interface Relay with the DeNB (Un RB) Relay, according to the mapping relationship Relay by mapping each UEl Relay Uu bearl , UEl Relay Uu bear2, UE2 Relay Uu bearl, UE2 Relay Uu bear2. [0076] 如果E-RAB的QoS类型数量小于或等于Un RB的数量,则可以将QoS —致的E-RAB 在同一个Un RB中传输,例如如图9所示,在仅有两条Un RB (Un RB N, Un RB N+1)的情况下传输如下表2所不的UE-E-RAB :[0077]表 2[0078] [0076] If the E-RAB QoS class number is less than or equal to the number of the Un RB, then QoS may be - E-RAB consistent Un RB in the same transmission, for example as shown in FIG. 9 only two Un RB (Un RB N, Un RB N + 1) in table 2 below are not transmitted to the UE-E-RAB conditions: [0077] tABLE 2 [0078]

Figure CN101932038BD00101

[0079] 该表中两个UE的四个E-RAB有两种QoS要求,DeNB按照QCI = 5为UEl E-RABl和UE2 E-RABl分配或者重配置一个Un RB,如图9所示为Un RB N ;DeNB按照QCI = 6为UEl E-RABl和UE2 E-RABl分配或者重配置一个Un RB,如图9所示为Un RB N+1。 [0079] The table UE four two E-RAB QoS requirements, there are two, DeNB UEl E-RABl and UE2 E-RABl allocated or a Un RB reconfiguration according to QCI = 5, as shown in FIG. 9 Un RB N; DeNB according QCI = 6 UEl E-RABl and UE2 E-RABl or reconfiguring a dispensing Un RB, as shown in FIG Un RB N + 1 9. [0080] 如果E-RAB的QoS类型数量大于Un RB的数量,则可以将QoS相同或相近的E-RAB 进行合并,利用合并的QoS来选择Un RB传输,例如如图9所示在仅有两条Un RB (UnRB N, UnRB N+1)的情况下传输如下表3所示的UE-E-RAB :[0081]表 3[0082] [0080] If the E-RAB QoS class number is larger than the number of the Un RB, may be the same or similar QoS E-RAB merging, the combined use of QoS transmission Un RB is selected, for example, as shown in FIG. 9 only table two below the transmission case Un RB (UnRB N, UnRB N + 1) shown in Figure 3 of the UE-E-RAB: [0081] table 3 [0082]

Figure CN101932038BD00111

[0083] 该表中两个UE有四个QoS要求,假设目前可用的Un RB数量只有2个,则可以将QCI等于5的UEl E-RABl单独分配或重配Un RB传输,Un RB的QoS要求按照QCI为5进行分配;而QCI为6、7、8的其他三个E-RAB共同使用同一个Un RB, Un RB的QoS按照QCI 为6的要求进行分配。 [0083] The UE table has two four QoS requirements, assumed that the number of currently available only Un RB 2, the QCI can be equal UEl E-RABl 5 or a separately allocated transmission Un RB reconfiguration, the QoS Un RB in accordance with claim 5 QCI is allocated; the other three QCI E-RAB 6,7,8 commonly use the same Un RB, Un RB is allocated in the QoS according to claim 6 QCI. [0084] 如果出现GBR类型QoS,QCI —致,但是GBR速率不一致的情况,按照相同QCI共同传输,且Un RB按照速率要求高的要求分配资源。 [0084] If the type GBR QoS, QCI occurs - induced, but inconsistent rate GBR case, a QCI transmitted together in the same, and a rate Un RB allocation resource demanding requirements. 例如如图9所示在仅有两条Un RB (UnRB N,UnRB N+1)的情况下传输如下表4所示的UE-E-RAB :[0085]表 4[0086] As shown in FIG. 9, for example, the case where the transmission only two Un RB (UnRB N, UnRB N + 1) in the following Table UE-E-RAB shown in: [0085] Table 4 [0086]

Figure CN101932038BD00112

[0087] 在这种情况下,UEl E-RABU UEl E-RAB2、UE2 E-RABl使用相同的Un RB,并按照GBR速率为30进行传输。 [0087] In this case, UEl E-RABU UEl E-RAB2, UE2 E-RABl same Un RB, and 30 according to the transmission rate of GBR. [0088] 需要指出的是,上述的实施例一同样适用于Relay与Relay之间的无线接入承载的传输。 [0088] It should be noted that a transmission of the above-described embodiments are equally applicable to and between Relay Relay radio access bearer. [0089] 下面再以Relay-E-RAB为例对上述的无线接入承载的传输方法进一步说明。 [0089] In the following further Relay-E-RAB an example of the above method for transmitting a radio access bearer described further. [0090] 在该实施例二中,其构架是通过Relay作为特殊UE接入EPC,Relay上的UE的控制面和用户面通过Relay的Relay-E-RAB传输。 [0090] In this second embodiment, the frame by which a special Relay UE accesses the EPC, the UE control plane and the user plane on Relay Relay-E-RAB transmitted through the Relay. Relay在Relay' s SGW/PGW上下文中区分出UE-E-RAB的QoS,根据与实施例一类似的方法为UE-E-RAB选择满足其QoS传输的Relay-E-RAB进行传输。 Relay distinguish UE-E-RAB QoS in Relay 's SGW / PGW context, transmitted according to a method similar to Example selecting UE-E-RAB meet its QoS transmission Relay-E-RAB. [0091] 如图10所示,在Relay的eNB属性部分和User-UE' s SGW/PGW存在UE的E-RAB, 简称为UE-E-RAB。 [0091] As shown, the presence of the attribute section 10 in the eNB and Relay User-UE 's SGW / PGW UE the E-RAB, abbreviated to UE-E-RAB. Relay 的UE 属性部分和Relay-UE' s SGW/PGW 之间存在Relay 的E-RAB, 简称为Realy-E-RAB。 Relay presence of E-RAB UE and the attribute portion Relay Relay-UE between 's SGW / PGW, abbreviated as Realy-E-RAB. 一条Realy-E-RAB 承载不同的UE-E-RAB。 A Realy-E-RAB bearer different UE-E-RAB. [0092] 如果UE-E-RAB的QoS类型数量小于或等于Realy-E-RAB的数量,可以将QoS —致的UE-E-RAB 在同一个Realy-E-RAB 中传输,例如在仅有两条Realy-E-RAB (Realy-E-RABl 和Realy-E-RAB2)的情况下传输如下表5所示的UE-E-RAB :[0093]表 5[0094] [0092] If the number of QoS class UE-E-RAB is equal to or less than the number Realy-E-RAB may be QoS - UE-E-RAB induced in the same Realy-E-RAB is transmitted, for example only two case Realy-E-RAB (Realy-E-RABl and Realy-E-RAB2) transmission following table UE-E-RAB shown in Figure 5: [0093] tABLE 5 [0094]

UE-E-RAB QoS参数UEl E-RABl QCI = 5UEl E-RAB2 QCI = 6UE2 E-RABl QCI = 5UE2 E-RAB2 QCI = 6[0095] 该表中两个UE的四个E-RAB有两种QoS要求,Relay UE' SGW/PGW的逻辑实体将按照QCI 等于5 的UEl E-RABl 和UE2 E-RABl 通过Realy-E-RABl 进行传输;Relay UE,SGff/ PGff的逻辑实体将按照QCI等于6的UEl E-RAB2和UE2 E-RAB2通过Realy_E_RAB2进行传输,以保证不同的QoS的实现。 UE-E-RAB QoS parameters UEl E-RABl QCI = 5UEl E-RAB2 QCI = 6UE2 E-RABl QCI = 5UE2 E-RAB2 QCI = 6 [0095] The two tables of four UE has two E-RAB QoS requirements, Relay UE 'SGW / PGW logical entity according QCI equal UEl E-RABl and UE2 E-RABl 5 is transmitted through Realy-E-RABl; Relay UE, SGff / PGff logical entities will be equal to 6 in accordance with the QCI the UEl E-RAB2 and UE2 E-RAB2 transmitted through Realy_E_RAB2, in order to ensure the realization of different QoS. [0096] 如果UE-E-RAB的QoS类型数量大于Realy-E-RAB承载的数量,可以将UE-E-RAB 按照QoS合并后选择Realy-E-RAB传输,例如在仅有两条Realy-E-RAB (Realy-E-RABl和Realy-E-RAB2)的情况下传输如下表6所示的UE-E-RAB :[0097]表 6[0098] [0096] If the number of types of QoS UE-E-RAB is greater than the number Realy-E-RAB bearer may be UE-E-RAB QoS combined in accordance with the selected transmission Realy-E-RAB, for example, only two Realy- the following table shows the transmission case 6 E-RAB (Realy-E-RABl and Realy-E-RAB2) of the UE-E-RAB: [0097] tABLE 6 [0098]

UE-E-RAB QoS参数UEl E-RABl QCI = 5UEl E-RAB2 QCI = 6UE2 E-RABl QCI = 8UE2 E-RAB2 QCI = 9[0099] 该表中两个UE有四个不同QoS的UE-E-RAB,则可以将QCI等于5的UEl E-RABl在Realy-E-RABI上传输;而QCI为6、7、8的其他三个UE-E-RAB共同使用同一个Realy-E_RAB2 传输。 UE-E-RAB QoS parameters UEl E-RABl QCI = 5UEl E-RAB2 QCI = 6UE2 E-RABl QCI = 8UE2 E-RAB2 QCI = 9 [0099] the UE has two tables of four different QoS UE-E -RAB, the QCI can be equal UEl E-RABl 5 transmitted on the Realy-E-RABI; QCI and three other UE-E-RAB 6,7,8 commonly use the same transmission Realy-E_RAB2. [0100] 如果UE-E-RAB出现GBR类型QoS,QCI 一致,但是速率不一致的情况,UE-E-RAB按照相同QCI使用相同的Realy-E-RAB传输,且传输速率要求满足合用Realy-E-RAB的最高GBR速率要求。 [0100] If the UE-E-RAB occurs GBR type QoS, consistent QCI, but inconsistent rate case, UE-E-RAB same Realy-E-RAB is transmitted according to the same QCI, and the transmission rate required to meet the combined Realy-E -RAB GBR highest rate requirements. 例如,在仅有两条Realy-E-RAB (Realy-E-RABl和Realy-E_RAB2)的情况下传输如下表Ί所示的UE-E-RAB :[0101]表 7[0102] For example, the following table the transmission UE-E-RAB Ί shown in the case where only two Realy-E-RAB (Realy-E-RABl and Realy-E_RAB2) is: [0101] Table 7 [0102]

Figure CN101932038BD00131

[0103]在这种情况下,UEl E-RABU UEl E_RAB2、UE2 E-RABl 使用相同的Realy-E-RAB I 进行传输,并按照GBR速率要求为30 ;UE2 E-RAB2使用Realy-E-RAB 2进行传输。 [0103] In this case, UEl E-RABU UEl E_RAB2, UE2 E-RABl same Realy-E-RAB I transmitted, and in accordance with requirements for the rate of GBR 30; UE2 E-RAB2 using Realy-E-RAB 2 for transmission. [0104] 需要特别指出的是,在同一个承载传输不同的UE-E-RAB之前,分配承载的网元需要隐式或显式的将承载标识与UE-E-RAB标识的对应关系告知被接受网元。 [0104] Of particular note is that before a different same bearer transport UE-E-RAB, the distribution network carrying element requires implicit or explicit carrying the correspondence between the identifier and the UE-E-RAB identifier inform accepted NE. [0105] 对应本发明的实施例一,DeNB的Un接口为UE RAB分配Un RB之后,DeNB通过E-RAB消息携带为此E-RAB分配的Un RB编号,通过UE的E-RAB消息携带并传送到Realy, Realy通过获取该信息可以获取哪些Un RB用于传输UE的E-RAB信息,这样分配数据无线承载(DRB)的网元就可以显式的将DRB编号与UE E-RAB的对应关系告知接受网元。 [0105] After the corresponding one embodiment of the present invention, the DeNB Un interface of an RAB to UE Un RB allocation, the DeNB Un RB carrying the E-RAB ID to this E-RAB assignment message by carrying the message from the UE through the E-RAB and transferred to Realy, Realy Un RB which may be acquired for transmission to the UE through the E-RAB information to obtain the information, so that distribution data radio bearer (DRB) network element may be DRB explicit UE ID and E-RAB corresponding to relations told to accept the network element. [0106] 较佳的,在DeNB的Un接口为UE RAB分配Un RB的时候,配置的Un RB序号按照默认约定的默认序号进行,例如可以按照QCI的值为Un RB分配相应的序号,QCI为I类型的UE RAB均从序号为I的Un RB上传输。 [0106] Preferably, the Un interface UE RAB allocated to the DeNB Un RB when the RB number configured by default convention Un default number for, for example, in accordance with the number corresponding to the value Un RB allocation QCI, QCI is I type of UE RAB are transmitted from the serial number of the I Un RB. [0107]对应本发明的实施例二,在 Relay-UE' s SGW/PGW 为UE-E-RAB 分配Relay-E-RAB 的时候,Re I ay-UE ' s SGW/PGW通过Re I ay-E-RAB的控制消息携带为此UE-E-RAB分配的Relay-E-RAB标识,通过UE的E-RAB控制消息携带并传送到Relay,Relay通过获取该信息可以获取哪些Relay-E-RAB用于传输该UE的E-RAB信息,这样分配承载的网元就可以显式的将承载编号与UEE-RAB的对应关系告知接受网元。 [0107] corresponding to two embodiments of the present invention, the Relay-UE 's SGW / PGW for the UE-E-RAB assignment Relay-E-RAB time, Re I ay-UE' s SGW / PGW by Re I ay- E-RAB control message carries UE-E-RAB assignment Relay-E-RAB ID for this, and transmitted to a control message carried by the Relay E-RAB of the UE, which Relay Relay-E-RAB information may be acquired by acquiring the E-RAB information for transmission to the UE, such that the dispensing can be carried NE explicit correspondence relationship between the carrier number and the UEE-RAB to inform the receiving network element. [0108]较佳的,在 Relay-UE's SGW/PGW 为UE-E-RAB 分配Relay-E-RAB 的时候,UE-E-RAB 所使用的Relay-E-RAB序号按照默认约定的默认标识进行,例如可以按照QCI的值为Relay-E-RAB分配相应的序号,QCI为I类型的UE-E-RAB均从序号为I的Relay-E-RAB上传输。 [0108] Preferably, performed for the UE-E-RAB assignment Relay-E-RAB time, Relay-E-RAB ID UE-E-RAB used by default agreed default identity in the Relay-UE's SGW / PGW , for example, in accordance with the number corresponding to the value of the QCI Relay-E-RAB assignment, each of the I QCI Relay-E-RAB the transmission of the I type from the UE-E-RAB ID. [0109] 另外,为了节省空口资源,在Un 口或者Relay与Relay空口数据无线承载(DRB) 传递UE的E-RAB时,可以仅传输GTP协议数据,GTP的承载UPD和IP协议并不传输。 [0109] Further, in order to save air interface resources, the Un interface or the Relay and Relay air interface data radio bearer (the DRB) transmitting E-RAB UE may transmit only the GTP protocol data, GTP bearer UPD and IP protocol does not transmit. 例如参考图11,Relay和DeNB传输的UE-E-RAB时的报文格式,Un RB仅传输GTP报文,不传输UDP和IP协议报文。 E.g. packet format with reference to FIG. 11, Relay and DeNB transmission UE-E-RAB, Un RB transmitting only the GTP packet, and the UDP does not transmit IP packets. [0110] 同样的参考图12,Relay和Relay-UE's SGW/PGW传输的UE-E-RAB时的报文格式, Relay-E-RAB中仅传输UE-E-RAB的GTP报文,没有传输UE-E-RAB的UDP和IP协议报文。 [0110] Also with reference to FIG. 12, the packet format of the Relay and Relay-UE's SGW / PGW transmission UE-E-RAB, Relay-E-RAB only transmit UE-E-RAB GTP packets, there is no transmission UE-E-RAB of the UDP and IP packets. [0111] 为了进一步节省空口资源,在承载UE-E-RAB时,UE-E-RAB的GTP头部可以仅携带必选字段,UE-E-RAB如果要求保序功能,将在DeNB侧和EPS网元之间实现,由于eNB和Relay之间、Re I ay和Relay之间、Re I ay和Relay-UE's SGW/PGW的承载来保证保序功能的完成。 [0111] In order to save air interface resources, when carrying UE-E-RAB, UE-E-RAB a GTP header may carry only mandatory fields, UE-E-RAB if desired order-preserving feature to the DeNB side and EPS achieved between NEs, since between the eNB and Relay Relay and between Re I ay, and Re I ay Relay-UE's SGW / PGW bearer order to ensure complete protection function. [0112] 对应本发明的实施例一,Un 口或者Relay与Relay空口数据无线承载(DRB)传递UE的E-RAB时,DeNB和EPS之间的UE的E-RAB承载通过Un接口传输到Relay网元中进行传输;这些E-RAB连接使用GTPU协议进行传输,传输的过程中如果需要保序功能的情况下, 也就是在需要传递GTPU序号(Sequence Number)以便保序功能实现的情况下,在DeNB侧进行保序功能的终结。 [0112] When the corresponding embodiment of the present invention a, Un interface or the Relay and Relay air interface data radio bearers (the DRB) transmitting the UE E-RAB, UE the E-RAB between DeNB and the EPS bearer Un interface transmission to the Relay NE for transmission; the connection GTPU protocol transmission, the transmission process of the E-RAB in circumstances requiring protection order function, that is, the need to pass GTPU number (sequence number) in order to protect the case where the order functions implemented, protection for termination sequences functional in DeNB side.
