Description

一种CRE偏置值的传输方法及基站 A method for transmitting CRE offset value and a base station

技术领域 FIELD

[0001] 本发明涉及通信领域,尤其涉及一种CRE偏置值的传输方法及基站。 [0001] The present invention relates to the field of communications, particularly to a transmission method and a base station CRE offset value.

[0002] 在异构网络(HetNet,Heterogeneous Network)中,以宏小区(macro cell)和微微蜂窝小区(pico cell)共享频谱的场景为例,由于pico cell和macro cell的发射功率差异较大,一般分别为30分贝毫(dBm)瓦和46dBm瓦,因此,pico cell中的用户设备(UE, User Equipment)在接收物理下行控制信道(PDCCH, Physical Downlink Control Channel) 上的数据时会受到来自macro cell的严重千扰,导致pico cell中的物理下行控制信道性能低下。 [0002] In a heterogeneous network (HetNet, Heterogeneous Network), a macro cell (macro cell) and pico cells (pico cell) shared spectrum scenario as an example, since the transmission power of the macro cell and the pico cell quite different, ml were typically 30 db (dBm) W and W 46dBm, therefore, will be from a macro user equipment (UE, user equipment) receiving data on a physical downlink control channel (PDCCH, physical downlink Control Channel) in a pico cell severe one thousand cell interference, resulting in low performance Pico physical downlink control channel in the cell.

[0003] 当pico cell 引入小区范围扩展(CRE, Cell Range Expansion)技术时,pico cell 中的roCCH的性能将更加恶化。 [0003] When introduced into the cell pico cell range expansion (CRE, Cell Range Expansion) technology, the pico cell roCCH performance will worsen. 例如,小区范围扩展技术中,当UE从Macro cell中运动到靠近Pico cell时,为了有效地减轻数据流量对宏小区的冲击,Macro cell所属的宏基站可以通过设置控制切换中偏移值来让UE更早地接入到Pico cell所属的微基站中。 For example, the cell range expansion technique, when the UE moves from the Macro cell close to the Pico cell, in order to effectively reduce the impact of data traffic on the macro cell, the macro base station Macro cell belongs can be controlled by setting the offset value to make the switch UE earlier access to the micro base station Pico cell belongs. 这种CRE技术相当于扩大了Pico cell的覆盖范围,扩大的这部分区域被称为Pico cell的小区扩展区域,这一偏移值可以称为该微基站对该宏基站的CRE偏置值。 This technique is equivalent to CRE improved coverage Pico cell of the enlarged part of this area is called a cell Pico cell of the extended area, the offset value may be referred to as CRE offset value of the micro base station to the macro base station.

[0004] 现有技术中,UE在经过小区扩展区域时容易产生乒乓(Pingpong)切换的现象,从而影响UE的通信质量,浪费网络通信资源。 [0004] In the prior art, when the UE passes prone cell expansion region pong phenomenon (Pingpong) handover, thus affecting the communication quality of the UE, a waste of network communication resources.

具体实施方式 Detailed ways

[0026]为了使得UE在移动过程中尽早的切换到目标小区中,引入了小区范围扩展技术。 [0026] In order to enable the UE during the movement to a target cell as soon as possible, the cell introduced range expansion technology. 例如,如图1A所示的宏小区与微小区的CRE示意图,UE在宏小区中进行业务传输,随着UE 移动,UE逐渐靠近微小区,为了减轻宏小区中的负载和业务流量,宏基站接收微基站发送的微小区对宏小区的CRE偏置值,并根据该CRE偏置值确定是否可以将UE尽早切换到微小区中。 For example, as shown in FIG 1A is a schematic view of the CRE macro cell and a micro cell, a macro UE for service transmission in the cell, as the UE moves, gradually approaches the microcell UE, and to reduce the load of traffic in the macro cell, the macro base station micro cell receives the micro base station transmitted CRE offset value of the macro cell, and determines whether the UE may switch to the micro cell as soon as the offset value based on the CRE. 宏基站可能根据微小区对宏小区的CRE偏置值将UE切换到了微小区,由于宏小区对微小区的CRE偏置值设置的不合理,在UE切换到了微小区,微基站却判断出该UE已经落入了宏小区的小区扩展区域中,导致微基站再将UE切换回宏基站,然后宏基站可能又根据微小区对宏小区的CRE偏置值将UE切换到微小区,依次反复来回切换而产生pingpong现象,导致UE无法正常进行通信业务。 The macro base station may CRE micro cell offset value to the macro cell UE to the micro cell, macro cell CRE unreasonable because the offset value provided micro cell, the UE switches to the micro cell, it is determined that the micro base station UE has fallen into the cell area of ​​the macro cell expansion, resulting in the micro base station and then switch back to the macro base station UE, the macro base station may then in turn according to the micro cell to the macro cell CRE offset value of the micro cell to handover the UE to turn back and forth repeatedly switching to produce pingpong phenomenon, leading business UE can not communicate properly.

[0027]再例如,参见图1B所示的微基站与相邻宏基站之间的CRE示意图。 [0027] For another example, referring to Figure 1B and a micro base station shown in schematic CRE between neighboring macro base station. 假设微小区对宏小区A的CRE偏置值确定出的CRE如图所示,而微小区对宏小区b之间不存在CRE,则UE 按照图1B中的UE路径移动时,UE的切换过程为:从宏小区A切换至微小区,从微基站切换至宏小区B,从宏小区B切换至微小区,从微小区切换至宏小区B,从而产生了pingpong现象。 Suppose shown CRE micro cell offset value to the macro cell A in FIG CRE-determined, and between the micro cell to the macro cell CRE B does not exist, the UE according to the UE a handover procedure of FIG. 1B movement path, the UE It is: a handover from a macro cell to the micro cell, handover from the micro cell to the macro base station B, B-cell handover from the macro to the micro-cell handover from the micro cell to the macro cell B, thereby generating a pingpong phenomenon.

[0028]下面将结合本发明实施例中的附图,对本发明实施例中的技术方案进行清楚、完整的描述,显然,所描述的实施例仅仅是本发明一部分实施例,而不是全部的实施例。 [0028] below in conjunction with the present invention in the accompanying drawings, technical solutions of embodiments of the present invention will be clearly and fully described, obviously, the described embodiments are merely part of embodiments of the present invention, but not all embodiments example. 基于本发明中的实施例,本领域普通技术人员在没有作出创造性劳动前提下所获得的所有其它实施例,都属于本发明保护的范围。 Based on the embodiments of the present invention, those of ordinary skill in the art without making all of the other embodiments given herein without creative efforts fall within the scope of the present invention.

[0029] 本发明实施例的第一基站和第二基站可以分别为:演进的基站(eNB)、基站(Node B)、基站(BS)、基站发信台(BTS)、接入点(AP)等;所述UE可以为接入终端(access terminal)、接入点(access point)、个人数字助理(PDA)、便携式电脑(laptop)等。 [0029] The first and second base stations embodiment of the present invention are: an evolved base station (eNB), a base station (Node B), a base station (BS), base transceiver station (BTS), an access point (AP ) and the like; the UE may access terminals (access terminal), an access point (access point), a personal digital assistant (PDA), a portable computer (Laptop) and the like. 第一基站既可以是宏基站也可以是微基站,第二基站既可以是宏基站也可以是微基站。 The first base station may be a macro base station may be either a micro base station, the second base station may be a macro base station may be either a micro base station.

[0030] 其中,在下述本发明实施例中,所称的CRE偏置值可以为CRE偏置值的绝对值,这里并不限制。 [0030] wherein, in the embodiments of the invention described below, the offset value may be referred to as CRE CRE absolute value of the offset value, it is not limited here.

[0031] 本发明实施例,一方面提供一种CRE偏置值的传输方法,如图2为该CRE偏置值的传输方法的流程示意图,该方法包括以下内容。 [0031] Example embodiments of the present invention, in one aspect provides a method for transmitting CRE offset value, 2 a schematic flowchart of a method for transmitting CRE offset value in FIG., The method including the following.

[0032] 步骤201,第一基站确定第一小区对第二小区的CRE偏置值;所述第一小区为所述第一基站下的小区,所述第二小区为第二基站下的小区,所述第一小区与所述第二小区为相邻的小区。 [0032] Step 201, the first base station determines a first offset value for the second cell CRE cells; the first cell is a cell of the first base station, the second cell is a cell of a second base station the first cell and the second cell is a neighboring cell.

[0033] 步骤202,所述第一基站将所述第一小区对所述第二小区的CRE偏置值发送给所述第二基站,所述第一小区对所述第二小区的CRE偏置值用于所述第二基站确定所述第二小区对第二小区的邻小区的CRE偏置值。 [0033] Step 202, the first base station transmits the first cell CRE offset value of the second cell to the second base station, the first cell of the second partial CRE cell setting value for the second cell of the second base station determines that a neighboring cell CRE offset value of the second cell.

[0034] 可选地,第一基站可以将第一小区对第二小区的CRE偏置值携带在移动性变更请求消息中发送给第二基站。 [0034] Alternatively, the first cell of the first base station may be a second cell carrying CRE offset value message sent to the second base station a mobility change request. 可以在现有移动性变更请求消息的基础上增加新的字段实现, 例如表1所不,增加了eNB (Pico)移动参数(Mobility Parameters)这一字段。 You can add a new field in the basis of the existing mobility change request message on, for example, Table 1 is not increased eNB (Pico) movement parameters (Mobility Parameters) this field. 第一小区对第二小区的CRE偏置值可以通过该字段来承载。 The first cell may be carried on the offset value of the second cell CRE by this field.

[0037] [0037]

[0038] 在步骤201中,第一基站确定的第一小区对第二小区的CRE偏置值,可以是由网络管理系统下发的,也可以是第一基站根据接收到的第一小区的邻小区对第一小区的CRE偏置值进行设置的。 [0038] In step 201, a first cell of the first base station determines the offset value for the second cell CRE, it may be sent by the network management system, the first base station may be received in accordance with a first cell of CRE neighbor cell offset value to be set in the first cell. 第一小区的邻小区,可以是第二小区也可以是除第二小区之外的、第一小区的其它邻小区。 A first neighboring cell cell, the second cell may be may be other than the second cell, the first cell of the other neighbor cells.

[0039] 步骤202中,第二小区的邻小区可以是第一小区,也可以是除了第一小区之外、第二小区的其它邻小区。 In [0039] Step 202, a second cell neighboring a first cell may be a cell, or may be in addition to a first cell, a second cell other neighbor cells.

[0040] 在本发明实施例中,第二基站将根据第一小区对第二小区的CRE偏置值确定的第二小区对第一小区的CRE偏置值发给第一基站,使得第一基站根据第二小区对第一小区的CRE偏置值对第一小区对第二小区的CRE偏置值进行调整,第一基站将第一小区对第二小区的CRE偏置值调整结果发给第二基站,使得第二基站进一步优化第二小区对第一小区的CRE偏置值,从而达到尽可能减少由于CRE偏置值设置不合理导致的pingpong现象。 [0040] In an embodiment of the present invention, the second base station will send a first base station to the CRE offset value according to the second cell of the first cell of a first cell of the second cell CRE offset value is determined such that the first CRE offset value to the base station of the first cell of the first cell CRE adjust the offset value of the second cell according to the second cell, the first cell of the first base station to adjust the offset value of the second CRE cell results to a second base station, such that the second base station the second cell CRE further optimized bias value for a first cell, so as to minimize the offset value CRE pingpong phenomenon caused due to unreasonable.

[0041] 作为一种可选实现方式,第二基站根据第一小区对第二小区的CRE偏置值确定第二小区对第二小区的邻小区的CRE偏置值时,可以包括: When [0041] In an optional implementation manner, the second base station determines a second offset value to neighbor cell CRE cells of the second cell of the second cell CRE offset value according to the first cell, may include:

[0042] 第二基站根据第一小区对第二小区的CRE偏置值确定第二小区对第一小区的CRE 偏置值,第二基站再将第二小区对第二小区的其它邻小区的CRE偏置值设为与第二小区对第一小区的CRE偏置值相同。 [0042] determining a second base station of the first cell of the second cell CRE offset value of the first cell of the second cell CRE offset value according to a second base station of the second cell and then the second cell of the other adjacent cell CRE offset value is set to the same as the second bias value of the first cell CRE cell. 作为一个示例,在第二基站根据第一小区对第二小区的CRE偏置值确定第二小区对第一小区的CRE偏置值的过程中,尽可能地使得第一小区对第二小区的小区扩展区域和第二小区对第一小区的小区扩展区域重叠部分最小。 As one example, a second cell of the second base station determines CRE offset value for the first cell of the second cell CRE offset value in accordance with the process of the first cell, the first cell as much as possible such that the second cell extended cell area and the second cell minimal overlapping part of the cell expansion area of ​​the first cell. 如图3所示的宏小区对微小区的CRE偏置值调整后的示意图。 Schematic view of the micro cell offset value to adjust the CRE macro cell shown in FIG. 3. 宏小区与微小区的小区扩展区域重叠部分相比图1A更小,UE在切换到微小区后,由于宏小区对微小区的CRE减少UE不易被再被切换到宏小区中,由此可以减少UE在宏小区和微小区的pingpong现象。 Compared with the macro cell cell extension region overlapping portion of the micro cell is smaller in FIG. 1A, UE after the handover to the micro cell, macro cell because the micro cell CRE UE can not easily be reduced again switched to the macro cell, thereby reducing UE pingpong phenomenon at the macro and micro cells. 因此,由于在网络部署后,宏小区和微小区的覆盖范围在理想条件下便确定下来,如果宏小区对微小区的CRE偏置值变大,则微小区需要对宏小区的CRE偏置变小,才可能保证小区扩展区域的范围变小或不变, 以使得Pingpong现象不会增加。 Accordingly, since the network deployment, coverage of the macro cell and micro-cells will be determined down under ideal conditions, if the macro cell to the micro cell CRE offset value becomes large, the micro cell to the macro cell need CRE offset becomes small, it is possible to ensure the extended range of the cell area is small or constant, so that the phenomenon does not increase Pingpong. 更进一步,如图4所示的微小区对宏小区的CRE偏置值调整后的不意图。 Still further, the micro-cells shown in FIG not intended CRE bias value after adjustment of the macro cell. 将微小区对宏小区B的CRE偏置值设置的与微小区对宏小区A的CRE偏置值相同,使得UE在经过微小区的小区扩展区域时,切换过程为从宏小区A切换至微小区,从微小区切换至宏小区B,与图1B相比,将大大减少pingpong现象的产生。 The micro cell to the macro cell CRE bias value B is set to the same as CRE micro cell offset value A of the macro cell, the UE such that the cell passes through the extended area of ​​the micro cell, a handover procedure to handover from the macro cell to the small-A area, handover from the micro cell to the macro cell B, as compared with FIG. 1B, will greatly reduce pingpong phenomenon.

[0043]可选地,上述方法还包括:步骤203,所述第一基站将标识信息发送给所述第二基站,所述标识信息用于确定所述第一小区。 [0043] Optionally, the method further comprises: Step 203, the first base station transmits the identification information to the second base station, determining the identification information for the first cell.

[0044]可选地,所述标识信息可以包括所述第一小区所属的公共陆地移动网络(PublicLandMobileNetwork,PLMN)。 [0044] Alternatively, the identification information may include a public land mobile network (PublicLandMobileNetwork, PLMN) of the first cell belongs. 在共享频谱的情况下,也就是第一小区或第二小区可能属于多个PLMN。 In the case of shared spectrum, that is, the first cell or the second cell may belong to a plurality of PLMN. 通常一个运营商至少对应一个PLMN。 Usually at least one operator corresponds to a PLMN. 例如,第一小区既属于A运营商又属于β运营商。 For example, a first cell belonging to both operators A and β belong to operators. 第二基站可以根据标识信息具体判断出第二小区在对第一小区CRE偏置值进行设置时是针对哪个PLMN的第二小区以及哪个PLMN的第一小区。 The second base station may specifically determines that the second cell is a second cell and the first cell of the PLMN to which the PLMN for which the first cell when the CRE offset value is set according to the identification information. 例如,可以是A运营商下的第二小区对A运营商下的第一小区的CRE偏置值,也可以是A运营商下的第二小区对B运营商下的第一小区的CRE偏置值,也可以是B运营商下的第二小区对a运营商下的第一小区的CRE偏移值。 For example, in the second cell of the first operator A to operator A cell in CRE-offset value, it may be a second cell under the bias of the operator A CRE first cell under the operator B set value, a second cell may be under the operator B cell at a first carrier offset value CRE. 可以在表1的基础上进一步增加承载第一网络标识对应的字段: serving PLMN,从而得到表2所示的移动性变更请求结构。 A first bearer network can be further increased corresponding to the identifier field on the basis of Table 1: serving PLMN, as shown in Table 2 to obtain a mobility change request structure.
