Description

通知方法、通知装置及系统 技术领域

目前，演进的通用陆地无线接入(Evolved Universal Terrestrial Radio Access，E-UTRA)中的小区的全球唯一身份，通过演进的小区全球标识符(Evolved Cell Global Identifier，ECGI)标识。具体的，ECGI包括公共陆地移动网络身份(Public Land Mobile Network Identity，PLMN Identity)和小区身份标识(Cell Identity)。图1为现有技术中ECGI包括的小区身份标识的示意图。
图1中，Cell Identity共占28位，其中高20位被配置为基站的标识(eNB ID)，可标识2^20＝1048576≈104万个基站；低8位被配置为小区的标识(Cell ID)，可标识2^8＝256个小区。
然而，上述的小区身份配置方法中，eNB ID被限制在104万个以内，而通信过程中，需要标识的基站少于104万个时，存在浪费，而当需要标识的基站多于104万个的情况，上述的小区身份配置方法对通信存在限制；同理，Cell ID被限制在256个，当一个基站能够支持的小区数小于256时，存在浪费，当一个基站能够支持的小区数大于256时，同样对通信存在限制。

具体实施方式
请参照图1，Cell Identity共占28位，其中高20位被配置为基站的标识(eNB ID)，可标识2^20＝1048576≈104万个基站；低8位被配置为小区的标识(Cell ID)，可标识2^8＝256个小区，经研究发现，图1所示的小区身份标识配置方法对通信存在一定的限制。例如，为提升E-UTRA网络覆盖区域中基站的容量，运营商通过采用站址加密的方式进行扩容，此时，上述的约104万个基站的容量无法满足运营商的需求，即Cell Identity包含的eNB ID无法满足需求；再如，当载波数较少时，上述的Cell Identity包含的8位的Cell ID存在浪费，如传统分布式基站采用3扇区组网的情况下，一个基站最大支持的小区数可能远远低于256；又如，现有的基于带宽的单元(Bandwidth Based Unit，BBU)最大支持144个小区，BBU下一代基带板能力更强，将会最大支持288个小区；又如，云无线接入网络(Cloud Radio Access Network，CRAN)场景下支持的最大小区数达到576，而上述的Cell Identity包含的8位的Cell ID最大仅支持256个小区。
有鉴于此，本发明实施例提供一种通知方法，通过灵活配置Cell Identity包括的eNB ID与Cell ID并通知给其他网元，如基站、核心网设备等，使得Cell Identity满足通信需求。
本文中描述的技术可用于各种通信系统，例如当前2G，3G通信系统和下一代通信系统，例如全球移动通信系统(Global System for Mobile communications，GSM)，码分多址(Code Division Multiple Access，CDMA)系统，时分多址(Time Division Multiple Access，TDMA)系统，宽带码分多址(Wideband Code Division Multiple Access Wireless，WCDMA)，频分多址(Frequency Division Multiple Addressing，FDMA)系统，正交频分多址(Orthogonal Frequency-Division Multiple Access，OFDMA)系统，单载波FDMA(SC-FDMA)系统，通用分组无线业务(General Packet Radio Service，GPRS)系统，长期演进(Long Term Evolution，LTE)系统，E-UTRA系统以及其他此类通信系统。

下面，为描述方便、清楚起见，以系统架构具体为E-UTRA系统、基站具体为eNB为例对本发明技术方案进行详细描述。具体的，请参见图2。

实施例一
图3为本发明通知方法实施例一的第一方法流程图，本实施例中，第一基站与第二基站或核心网设备交互，适用于第一基站与核心网设备或第二基站通信过程中，需要对小区的Cell Identity进行灵活配置的场景。具体的，本实施例包括如下步骤：
101、第一基站为第一小区配置第一小区身份标识，所述第一小区身份标识包括第一标识域和第二标识域，所述第一标识域中的预定位与所述第二标识域用于标识所述第一小区，所述第一标识域中的剩余位用于标识所述第一基站；或者，所述第二标识域中的预定位与所述第一标识域用于标识所述第一基站，所述第二标识域中的剩余位用于标识所述第一小区。
本发明实施例中，第一基站为eNB，第一小区例如为第一基站所属的小区中的任意一个。现有技术中，第一标识域的长度与第二标识域的长度的和为第一小区身份标识总长度，其中，第一标识域用于标识第一基站，第二标识域用于标识第一小区。而本步骤中，在保持第一小区身份标识的总长度不变的情况下，通过借位的方法灵活配置小区身份标识。
例如，当通信过程中，需要标识的基站的数量受限时，第一基站通过将第一小区身份标识中原本用于标识第一小区的第二标识域中的预定位挪用至第一标识域，也即将第二标识域中的预定位与第一标识域的组合用于标识第一基站。其中，第二标识域中的预定位例如为第二标识域中的高Y位，Y为整数且小于第二标识域的长度。具体的，可参见图4A，图4A为本发明通知方法实施例一中一种Cell Identity的示意图。如图4A所示，当第一Cell Identity具体为28位、第一标识域为20位、第二标识域为8位时，可以将第二标识域中的Y位(预定位)与第一标识域的20位组合起来标识第一基站，而将第二标识域中的剩余位，即8-Y位用于标识第一小区。
再如，当通信过程中，需要标识的小区的数量受限时，第一基站通过将第一小区身份标识中原本用于标识第一基站的第一标识域中的预定位挪用至第二标识域，也即将第一标识域中的预定位与第二标识域的组合用于标识第一小区。其中，第一标识域中的预定位例如为第一标识域中的低X位，X为整数且小于第一标识域的长度。具体的，可参见图4B，图4B为本发明通知方法实施例一中另一种小区身份标识的示意图。如图4B所示，当第一小区身份标识具体为28位、第一标识域为20位、第二标识域为8位时，可以将第一标识域中的X位(预定位)与第二标识域的8位组合起来标识第一小区，而将第一标识域中的剩余位，即20-X位用于标识第一基站。
102、所述第一基站向第二基站或核心网设备通知所述第一小区身份标识中标识所述第一小区的部分，或者所述第一小区身份标识中标识所述第一基站的部分。
第一基站在为第一小区配置好第一小区身份标识后，向第二基站或核心网设备通知第一小区身份标识中标识第一小区的部分，或者，第一小区的小区身份标识中标识第一基站的部分。该通知过程中，根据需求两者都发送或只发送其中的一个。
本发明实施例提供的通知方法，为属于第一基站的第一小区配置小区身份标识时，在保持小区身份标识的总长度不变的情况下，通过挪用借位的方法灵活配置小区身份标识。该过程中，突破现有技术中将28位的小区身份标识中的高20位用于标识eNB，低8位用于标识cell ID的限制，而是通过借位的方法，灵活配置小区身份标识，使得小区身份标识中用于标识eNB的部 分不限于高20位，用于标识Cell ID的部分不限于低8位。这样，当28位的小区身份标识中，超过20位用于标识eNB时，使得小区身份标识可标识的eNB超过现有技术中104万个的限制，极大程度上提高的小区身份标识可标识的eNB的数量，使得小区身份标识满足通信需求；同理，当28位的小区身份标识中，超过8位用于标识小区时，使得小区身份标识可标识的小区超过现有技术中256个的限制，极大程度上提高的小区身份标识可标识的小区的数量，使得小区身份标识满足通信需求。另外，该过程中，当eNB支持的小区的数小于256时，通过将28位的小区身份标识中，少于8位用于标识小区，从而减少信令浪费。
上述通知过程中，小区身份标识的总长度不变，且小区身份标识中eNB ID与Cell ID划分对终端不可见，终端仅需要知道ECGI即可，因此，对空口不会造成影响。但是，第一基站与第二基站采用X2协议进行通信，第一基站与MME或S-GW等核心网设备采用S1接口协议进行通信，而以上通信的过程中，第二基站或核心网设备需要知道第一基站对小区身份标识的新的划分方式，也即小区身份标识中哪些部分用于标识第一基站，哪些部分用于标识第一小区。因此，第一小区身份标识中eNB ID与Cell ID划分对S1接口协议与X2接口协议造成影响，需要向第二基站或核心网设备通知所述第一小区身份标识中标识第一小区的部分和所述第一小区身份标识中标识所述第一基站的部分中的至少一个。具体的，可通过如下三种方式进行通知：
方式一、所述第一基站向第二基站或核心网设备发送所述第一小区身份标识；所述第一基站向第二基站或核心网设备发送第一指示信息，所述第一指示信息用于指示所述第一小区身份标识中用于标识所述第一基站的部分的位置，或者用于指示所述第一小区身份标识中用于标识所述第一小区的部分的位置。
该种方式下，第一基站将第一小区身份标识中，用于标识第一基站的部分的位置，和/或，用于标识第一小区的部分的位置，通知给第二基站或核心网设备。
例如，再请参照图4A，当预定位为第二标识域的高Y(1≤Y＜8)位时，则第一指示信息指示总长度为28位的第一小区身份标识中，用于标识第一基站的部分的位置为高20+Y位，用于标识第一小区的部分的位置为低8-Y位。
再如，再请参照图4B，当预定位为第一标识域的低X(1≤X＜20)位时，则第一指示信息指示总长度为28位的第一小区身份标识中，用于标识第一基站的部分的位置为高20-X位；用于标识第一小区的部分的位置为低X+8位。
方式二、所述第一基站向第二基站或核心网设备发送所述第一基站的标识。
该种方式下，第一基站将第一小区身份标识中用于标识第一基站的部分，即第一基站的标识直接通知给第二基站或核心网设备。，将第一小区身份标识中标识第一基站的部分定义为一个新的信元(Information Element，IE)，例如，当用于标识第一基站的位数少于20位时，可以定义为缩减eNB ID(Reduced eNB ID)，将该Reduced eNB ID发送给第二基站或者核心网设备。该过程中，第二基站或者核心网设备收到该新定义的Reduced eNB ID，则将其代替第一小区身份标识中原来用于标识第一基站的部分，即第一标识域作为当前第一基站的标识。
方式三、第一基站向第二基站或核心网设备通知预定位的位置。
例如，再请参照图4A，当预定位为第二标识域的高Y(1≤Y＜8)位时，则第一基站向第二基站或核心网设备通知：第一小区身份标识中预定位的位置为高Y位，即Cell ID右移Y位，使得第一小区身份标识中，低8-Y位用于标识第一小区，高20+Y位用于标识第一基站。
再如，再请参照图4B，当预定位为第一标识域的低X(1≤X＜20)位时，则第一基站向第二基站或核心网设备通知：第一小区身份标识中预定位的位置为低X位，即Cell ID左移X位，使得第一小区身份标识中，低X+8位用于标识第一小区，高20-X位用于标识第一基站。
接下来，将结合S1接口协议或者X2接口协议中涉及到的一些具体流程，对发明的技术方案做进一步说明。
关于本发明技术方案在S1接口协议流程中的应用：
具体的，第一小区身份标识中eNB ID与Cell ID的划分影响的IE有目标基站身份标识(Target ID)、全球基站身份标识(Global eNB ID)、E-UTRAN全球小区识别码(E-UTRAN Cell Global Identifier，E-UTRAN CGI)、自组织网络配置迁移(self-organized Network Configuration Transfer，SON Configuration Transfer)等。影响的过程包括：切换请求(HANDOVER  REQUIRED)、S1建立请求(S1SETUP REQUEST)、PWS重启指示(PWS RESTART INDICATION)、eNB配置转移(eNB CONFIGURATION TRANSFER)、MME配置转移(MME CONFIGURATION TRANSFER)、位置报告(Location Report)等。
此时，第一基站向第二基站或核心网设备通知第一小区身份标识中标识第一小区的部分，或第一小区身份标识中标识第一基站的部分中。
另外，当进行基站间小区切换、小区重建等流程时，第一基站还获取第二小区的第二小区身份标识，所述第二小区身份标识包括第三标识域和第四标识域，所述第三标识域中的预定位与所述第四标识域用于标识所述第二小区，所述第三标识域中的剩余位用于标识第二基站；或者，所述第四标识域中的预定位与所述第三标识域用于标识所述第二基站，所述第四标识域中的剩余位用于标识所述第二小区；所述第一基站向所述第二基站或所述核心网设备通知所述第二小区身份标识中标识所述第二小区的部分，或者所述第二小区身份中标识所述第二基站的部分，其中，所述第二小区属于所述第二基站。

对于MME配置转移过程，现有技术中，移动管理实体将第一基站的Global eNB ID和第二基站的Global eNB ID通知给第一基站，而本发明实施例中，当采用上述的方式二时，第一基站向移动管理实体发送第一基站的标识；
对于位置报告过程，现有技术中，第一基站将第一小区身份标识通知给MME，而本发明实施例中，当采用上述方式一时，第一基站将第一指示信息携带在位置报告消息中发送给移动管理实体，该第一指示信息用于指示第一 小区身份标识中用于标识第一基站的部分的位置或者用于指示第一小区身份标识中用于标识第一小区的部分的位置对于eNB配置转移过程，现有技术中，第一基站将第一基站的Global eNB ID和第二基站的Global eNB ID通知给移动管理实体，而本发明实施例中，将指示信息携带在eNB配置转移消息中发送给移动管理实体，该指示信息用于指示第一小区身份标识中用于标识第一基站的部分的位置，或者用于指示第一小区身份标识中用于标识第一小区的部分的位置以及第二小区身份标识中用于标识第二基站的部分的位置，或者用于指示第二小区身份标识中用于标识第二小区的部分的位置；另一种方法：第一基站向移动管理实体发送第一基站的标识和第二基站的标识；

本发明中所涉及到的X2接口协议流程中，需要在交互中对原有的IE进行指示或者更新的IE，可以参照TS36.423中9.2.8、9.2.14、9.2.21、9.2.22、9.2.40、9.2.56、9.2.68、9.2.75、9.2.76、9.1.2.3、9.1.2.4、9.1.2.23、9.1.2.25、9.1.2.26、9.1.1.1、9.1.2.24、9.1.2.1、9.1.2.8、9.1.2.11、9.1.2.12、9.1.2.13、9.1.2.14、 9.1.2.15、9.1.2.16、9.1.2.17、9.1.2.18、9.1.2.19、9.1.2.20、9.1.2.21中与小区身份标识、eNB ID,或者cell ID相关的IE。
可选的，上述实施例中，所述小区身份标识包含28位，所述第一标识域包含20位，所述第二标识域包含8位，所述第一标识域中的预定位包含X位，1≤X＜20，X为整数；所述第二标识域中的预定位包含Y位，1≤Y＜8，Y为整数。
图5为本发明通知方法实施例一的第二方法流程图，本实施例中，第一基站与终端交互，适用于第一基站与终端通信过程中，需要对小区的小区身份标识进行灵活配置并通知给终端的场景。具体的，本实施例包括如下步骤：
201、第一基站为第一小区配置第一小区身份标识，所述第一小区身份标识包括第一标识域和第二标识域，所述第一标识域中的预定位与所述第二标识域用于标识所述第一小区，所述第一标识域中的剩余位用于标识所述第一基站；或者，所述第二标识域中的预定位与所述第一标识域用于标识所述第一基站，所述第二标识域中的剩余位用于标识所述第一小区，其中，所述第一小区属于所述第一基站。
具体的，可参见上述图3步骤101，此处不再赘述。
202、所述第一基站向终端通知所述第一小区身份标识。
第一基站在为第一小区配置好第一小区身份标识后，向终端通知第一小区身份标识。
具体的，第一基站向终端发送第一小区的小区全球标识符ECGI，该ECGI包括公共陆地移动网络标识与第一小区身份标识。
203、所述终端识别所述第一小区。
具体的，终端对ECGI进行解析，解析出第一小区身份标识，进而根据该第一小区身份标识识别出第一小区。
本发明实施例提供的通知方法，为属于第一基站的第一小区配置第一小区身份标识时，在保持小区身份标识的总长度不变的情况下，通过借位的方法灵活配置小区身份标识。该过程中，突破现有技术中将28位的小区身份标识中的高20位用于标识eNB，低8位用于标识cell ID的限制，而是通过借位的方法，灵活配置小区身份标识，使得小区身份标识中用于标识eNB的部 分不限于高20位，用于标识Cell ID的部分不限于低8位。如此一来，当28位的小区身份标识中，超过20位用于标识eNB时，使得小区身份标识可标识的eNB超过现有技术中104万个的限制，极大程度上提高的小区身份标识可标识的eNB的数量，使得小区身份标识满足通信需求；同理，当28位的小区身份标识中，超过8位用于标识小区时，使得小区身份标识可标识的小区超过现有技术中256个的限制，极大程度上提高的小区身份标识可标识的小区的数量，使得小区身份标识满足通信需求。另外，该过程中，当eNB支持的小区的数小于256时，通过将28位的小区身份标识中，少于8位用于标识小区，从而减少信令浪费。
可选的，上述实施例中，第一基站还向第二基站或核心网设备通知所述第一小区身份标识中标识所述第一小区的部分，或者所述第一小区身份标识中标识所述第一基站的部分。
具体的，通知过程中，所述第一基站向第二基站或核心网设备发送所述第一小区身份标识；所述第一基站向第二基站或核心网设备发送第一指示信息，所述第一指示信息用于指示所述第一小区身份标识中用于标识所述第一基站的部分的位置，或者用于指示所述第一小区身份标识中用于标识所述第一小区的部分的位置；或者，所述第一基站向第二基站或核心网设备发送所述第一基站的标识，详细描述可参见上述图3实施例中关于102的描述，此处不再赘述。

所述第一基站向所述第二基站或所述核心网设备通知所述第二小区身份标识中标识所述第二小区的部分，或者所述第二小区身份中标识所述第二基站的部分，其中，所述第二小区属于所述第二基站。
实施例二
上述实施例一中，在保持小区身份标识的总长度不变的情况下，通过挪用借位的方法灵活配置小区身份标识。然而，本发明并不以此为限，在其他 可行的实现方式中，也可以不保存小区身份标识的总长度不变，即扩展小区身份标识的长度，从而实现对小区身份标识的灵活配置。
首先，第一基站对小区身份标识进行灵活配置并通知给第二基站或核心网设备。
具体的，第一基站为第一小区配置小区身份标识，所述小区身份标识包括第一标识域、第二标识域和第三标识域，所述第一标识域与所述第二标识域用于标识所述第一基站，所述第三标识域用于标识所述第一小区；或者，所述第一标识域用于标识所述第一基站，所述第二标识域与所述第三标识域用于标识所述第一小区。下面，请参照图6A、图6B与图6C，小区身份标识扩展前长度为28位、扩展后长度为28+Y位，即扩展Y位为例，对本发明实施例进行详细讲解。
图6A为本发明通知方法实例二中一种小区身份标识的示意图。请参照图6A，当第一标识域为20位、第二标识域为Y位、第三标识域为8位时，可将第一标识域与第二标识域用于标识第一基站，即将小区身份标识中20+Y位用于标识第一基站，8位用于标识第一小区。
图6B为本发明通知方法实施例二中另一种小区身份标识的示意图。请参照图6B，当第一标识域为20位、第二标识域为Y位、第三标识域为8位时，可将第二标识域与第三标识域用于标识第一小区，即将小区身份标识中20位用于标识第一基站，Y+8位用于标识第一小区。
图6C为本发明通知方法实施例二中又一种小区身份标识的示意图。请参照图6C，当第一标识域为20位、第二标识域为Y位、第三标识域为8位时，可以将第二标识域划分为两部分，第一部分的长度为Y1，第二部分的长度为Y2，Y1、Y2为正整数，且Y1+Y2＝Y，此时，第一标识域与第一部分用于标识第一基站，即将小区身份标识中的20+Y1位用于标识第一基站，将Y2+8位用于标识第一小区。
在为第一小区配置好小区身份标识后，第一基站向第二基站或核心网设备通知小区身份标识中标识第一小区的部分，或者小区身份标识中标识所述第一基站的部分。具体的，发送过程中，第一基站可以向第二基站或核心网设备发送第一指示信息，该第一指示信息用于指示扩展后的小区身份标识中用于标识第一基站的部分的位置，或者用于指示小区身份标识中用于标识第 一小区的部分的位置；或者第一基站可以向第二基站或核心网设备发送第二指示信息，该第二指示信息用于指示第二标识域，即扩展的标识域的位置。另外，也可以通过其他方式进行发送，本发明并不以此为限制。
本发明实施例提供的通知方法，为属于第一基站的第一小区配置小区身份标识时，通过扩展小区身份标识的长度，对小区身份标识包括的eNB与Cell ID进行灵活配置。该过程中，突破现有技术中小区身份标识的总长度为28位的限制，即将小区身份标识扩展为28+Y位。如此一来，当28+Y位中超过20位用于标识eNB时，使得小区身份标识可标识的eNB超过现有技术中104万个的限制，极大程度上提高的小区身份标识可标识的eNB的数量，使得小区身份标识满足通信需求；同理，当28+Y位的小区身份标识中，超过8位用于标识小区时，使得小区身份标识可标识的小区超过现有技术中256个的限制，极大程度上提高的小区身份标识可标识的小区的数量，使得小区身份标识满足通信需求。
可选的，上述信息发送过程中，小区身份标识的总长度发生变化，这将会对空口造成影响，因此，相关协议，如X2接口协议、S1接口协议、Uu接口协议等需要进行改动，使得通信的相关过程得到UE等的支持。
可选的，上述实施例中，所述第一基站向第二基站或核心网设备通知第二小区的小区身份标识和所述第二小区的小区身份中标识所述第二基站的部分中的至少一个，所述第二小区属于所述第二基站。
其次，第一基站对小区身份标识进行灵活配置并通知终端。
该过程中，第一基站为第一小区配置小区身份标识，所述小区身份标识包括第一标识域、第二标识域和第三标识域，所述第一标识域与所述第二标识域用于标识所述第一基站，所述第三标识域用于标识所述第一小区；或者，所述第一标识域用于标识所述第一基站，所述第二标识域与所述第三标识域用于标识所述第一小区。具体的，可参见上述第一基站对小区身份标识进行灵活配置并通知第二基站或核心网设备的描述，此处不再赘述。
第一基站在为第一小区配置好小区身份标识后，向终端通知小区身份标识。具体的，第一基站向终端发送第一小区的小区全球标识符ECGI，该ECGI包括公共陆地移动网络标识与该小区身份标识。
实施例三
相较于上述实施例一中，在保持小区身份标识的总长度不变的情况下，通过挪用借位的方法灵活配置小区身份标识，以及上述实施例二中，通过扩展小区身份标识的长度，从而实现对小区身份标识的灵活配置，本实施例中，通过为同一个基站配置至少两个不同的eNB ID，使得小区身份标识可标识的eNB的数量不受限制。
具体的，第一基站配置用于标识自身的基站标识，所述基站标识至少为两个，且互不相同，然后，所述第一基站向第二基站或者核心网设备发送第一信息，所述第一信息用于指示所述基站标识中的至少两个用于标识所述第一基站。
本步骤实施例中，第一基站配置多个基站标识。例如，当小区身份标识包含28位，其中eNB ID包含20位时，根据现有协议可知，可标识2^20＝1048576≈104万个基站。，本步骤中，第一基站将多个标识中的至少两个配置为自身的基站标识。当第一基站为自身配置好至少两个基站标识后，第一基站向第二基站或核心网设备发送第一信息，以指示该至少两个基站标识为第一基站的标识。也就是说，第一基站具有至少两个不同的基站标识。如此一来，第一基站服务的最大小区数即可超过256。例如，当第一基站使用三个eNB ID时，该第一基站服务的最大小区个数可达到768。
本发明实施例提供的通知方法，第一基站为自身配置至少两个基站标识，然后，第一基站向第二基站或者核心网设备发送第一消息，该第一消息包含用于指示该至少两个基站标识用于标识同一个基站。该过程中，通过为同一个基站配置至少两个不同的基站标识，使得同一个基站服务的最大小区数增加，进而使得小区身份标识满足通信需求。
上述通知方法中，当第一基站使用多个基站标识(例如三个不同的基站标识)时，从逻辑的角度来讲，不同基站标识标识的基站相当于多个不同的基站。此时，当第一基站需要与第二基站建立X2接口，或者需要与MME建立S1接口时，需要建立多次，信令开销大。但是，实质上，多个不同基站标识对应的物理基站均为第一基站，因此，X2接口建立过程中，只需要建立一次即可，同理，S1接口建立过程中，也只需要建立一次。本发明实施例中，可采用如下方案避免同一个基站使用多个基站标识时带来的信令开销浪费问题。
具体的，为避免多次建立X2接口，可将X2建立请求(X2SETUP REQUEST)作为第一消息，将指示至少两个基站标识为第一基站的基站标识的信息携带在第一消息中发送给第二基站，该第二基站例如为需要与第一基站建立X2接口的基站，从而向第二基站指示至少两个基站标识对应的基站实质上为同一个基站，只需要建立一次X2接口即可。同理，为避免多次建立S1接口，可将S1建立请求(S1SETUP REQUEST)作为第一消息，将指示至少两个基站标识为第一基站的基站标识的信息携带在第一消息中发送给MME，从而向MME指示至少两个基站标识对应的基站实质上为同一个基站，只需要建立一次S1接口即可。
以上描述的是当为第一基站配置至少两个不同的eNB ID时，如何避免对S1接口建立和X2接口建立的影响。然而，对第一基站配置至少两个不同的eNB ID，除了对S1接口建立和X2接口建立有影响外，还对小区切换造成影响。具体的，当终端在第一基站下的两个小区进行切换时，例如，当终端从第一基站下的第一小区移动到第二小区时，该切换实质上是第一基站内的小区切换。但是，本发明实施例中，第一基站具有至少两个不同的eNB ID，可能导致第一小区的小区身份标识中的eNB ID与第二小区的小区身份标识中的eNB ID不同。因此，从逻辑的角度来讲，该小区切换实质为基站间的切换。一般来说，基站间进行小区切换时，基站与核心网设备之间需要进行路径切换(Path Switch)过程，这将造成不必要的信令开销浪费。本发明实施例中，对于具有至少两个eNB ID的第一基站，各个eNB ID对应的基站使用同一个eNB IP地址，域名系统(Domain Name System，DNS)只需要维护一个域名。为避免信令开销浪费问题，当逻辑上的两个基站间的切换为基于X2接口的切换时，将切换请求(HANDOVER REQUEST)消息中作为第一消息，且在该第一消息中携带指示多个基站标识中至少两个为第一基站的基站标识的信息，从而告知目标基站：源基站与目标基站对应同一个物理基站，目标基站与核心网之间无需执行Path Switch过程。当逻辑上的两个基站间的切换为基于S1接口的切换时，将切换请求(HANDOVER REQUIRED)消息作为第一消息，且在该第一消息中携带指示多个基站标识中至少两个为第一基站的基站标识的信息，从而告知MME：终端将切换至的目标基站与源基站实质上为同一个物理基站，目标基站与核心网间无需执行Path  Switch过程。
