下面通过附图和实施例, 对本发明的技术方案做进一步的详细描述。 在本发明实施例中, UE可以由基站 eNBl和基站 eNB2共同服务,其中 eNBl 为主服务基站, eNB2 为辅服务基站,也可以称为辅基站、 协作基站、 小小区 节点、 低功率节点、 中继站、 家庭基站、 小基站、 微基站、 微微基站、 或宏 基站等。 在本发明实施例中, 辅基站的个数可以为一个, 也可以为多个。
图 1和图 2为本发明第一实施例和第二实施例数据交互的方法的流程图, 第一实施例是主基站的处理过程, 第二实施例是辅基站的处理过程, 第一实 施例和第二实施例的主基站和辅基站利用 S1接口进行交互的。
图 1为本发明第一实施例数据交互的方法的流程图, 如图所示, 本实施 例的方法包括如下步骤:
步骤 101 , 辅基站接收主基站发送的第一消息, 或接收操作管理维护系 统配置的所述辅基站和所述主基站的关系信息, 其中, 所述第一消息用于通 知所述辅基站建立 S1接口;
例如, 因为主基站 eNBl希望和辅基站 eNB2之间建立 S1接口,从辅基站 eNB2的角度,主基站 eNBl就被当做一个特殊的核心网节点。从而主基站 eNBl 可以对辅基站 eNB2进行 UE上下文管理和 7 载管理, 例如, 在主基站 eNBl和 辅基站 eNB2之间使用 S1AP协议 3GPP TS 36. 413中的 UE上下文管理, 及承 载管理流程。
可选的, S1接口是用于基站间协作服务的 S1接口, S1接口建立需求 S1 SETUP REQUIRED/ INVOKE 消息中携带基站间协作服务标识, 例如, S1接口建 立需求中记录命名的字段中包含基站间协作服务信息;
该基站间协作服务可以是基站间协作传输、 基站间 CoMP、 基站间载波聚 合、 或基站间多流服务等等;
在本步骤主基站 eNBl向辅基站 eNB2发送 S1接口建立需求,使得辅基站 eNB2得知主基站 eNBl希望与辅基站 eNB2之间建立 S1接口, 可以利用其他 方式使得辅基站 eNB2得知主基站 eNBl希望与辅基站 eNB2之间建立 S1接口, 例如:
操作管理维护系统 ( Operat ion Admini s trat ion and Ma intenance, 0AM ) 向主基站和 /或辅基站发送 0AM配置的关系信息; 和 /或, S1接口建立需求中 携带基站间协作服务标识。
所述关系信息为主基站和辅基站的对应关系, 或控制节点与被控制节点 的对应关系。
步骤 102 , 所述辅基站向所述主基站发送 S1接口建立请求;
例如, 辅基站 eNB2收到该 S1接口建立需求, 或者辅基站 eNB2接收到 0AM发送的关系信息后, 得知主基站 eNBl需要辅基站 eNB2请求辅助主基站 eNBl服务 UE, 若辅基站 eNB2同意, 则向主基站 eNBl发送 S1接口建立请求 SI SETUP REQUEST消息。 该建立请求是从辅基站 eNB2发给主基站 eNBl的, 可以携带基站间协作服务标识。
步骤 103 , 接收所述主基站发送的 S1接口建立响应;
如果主基站 eNBl允许该 S1接口建立,则向辅基站发送 S1接口建立响应 SI SETUP RESPONSE 消息, 该消息中可以携带基站间协作服务标识, 如果主 基站 eNBl 不允许该 S1 接口建立, 则向辅基站回复 S1 建立失败 SI SETUP FAILURE消息。
步骤 104 , 所述辅基站通过 SI接口和所述主基站进行交互。 例如, 辅基 站和主基站之间建立 S1接口连接, 通过 S1接口进行数据交互。
主基站 eNBl和辅基站 eNB2之间建立了 S1接口, 后续重用 UE上下文管 理及承载管理功能, 来实现基站间的协作传输服务。 从 UE 的角度来看, 该 UE的 S1接口可以通过 eNBl连接到移动性管理实体(Mobi l i ty Management Ent i ty, E )。 在现有技术中, eNB2并不直接和该 UE的服务 MME交互该 UE 的信息。 在本实施例中, eNB2能够通过与 eNBl直接的 S1接口连接到该 UE 的服务 E上, 从而能够和该 UE的服务 E交互该 UE的信息。
本实施例的数据交互的方法实现了由主基站触发或者 0AM配置后, 由辅 基站发起 S1接口建立请求, 从而建立了能够双向传输数据的 S1接口, 实现 了利用 S1接口在主基站和辅基站之间进行双向数据交互。 图 2为本发明第二实施例数据交互的方法的流程图, 如图所示, 本实施 例的方法包括如下步骤:
步骤 201 , 主基站向辅基站发送第一消息, 第一消息用于通知辅基站建 立 S1接口;
例如, 因为主基站 eNBl希望和辅基站 eNB2之间建立 S1接口,从辅基站 eNB2的角度,主基站 eNBl就被当做一个特殊的核心网节点。从而主基站 eNBl 可以对辅基站 eNB2进行 UE上下文管理和 7 载管理, 例如, 在主基站 eNBl和 辅基站 eNB2之间使用 S1AP协议 3GPP TS 36. 413中的 UE上下文管理, 及承 载管理流程。
可选的, S1接口是用于基站间协作服务的 S1接口, S1接口建立需求 S1 SETUP REQUIRED/ INVOKE 消息中携带基站间协作服务标识, 例如, S1接口建 立需求中记录命名的字段中包含基站间协作服务信息; 该基站间协作服务可以是基站间协作传输、 基站间 CoMP、 基站间载波聚 合、 或基站间多流服务等等;
在本步骤 201主基站 eNBl向辅基站 eNB2发送 SI接口建立需求,使得辅 基站 eNB2得知主基站 eNBl希望与辅基站 eNB2之间建立 S1接口, 可以利用 其他方式使得辅基站 eNB2得知主基站 eNBl希望与辅基站 eNB2之间建立 S1 接口, 例如:
操作管理维护系统 ( Operat ion Admini s trat ion and Ma intenance, 0AM ) 向主基站和 /或辅基站发送 0AM配置的关系信息; 和 /或, S1接口建立需求中 携带基站间协作服务标识。
所述关系信息为主基站和辅基站的对应关系, 或控制节点与被控制节点 的对应关系。
步骤 202 , 主基站接收辅基站发送的 S1接口建立请求;
例如, 辅基站 eNB2收到该 S1接口建立需求, 或者辅基站 eNB2接收到
0AM发送的关系信息后, 得知主基站 eNBl需要辅基站 eNB2请求辅助主基站 eNBl服务 UE, 若辅基站 eNB2同意, 则向主基站 eNBl发送 S1接口建立请求
SI SETUP REQUEST消息。 该建立请求是从辅基站 eNB2发给主基站 eNBl的, 可以携带基站间协作服务标识。
步骤 203 , 主基站向辅基站发送 S1接口建立响应;
如果主基站 eNBl允许该 S1接口建立,则向辅基站发送 S1接口建立响应 SI SETUP RESPONSE 消息, 该消息中可以携带基站间协作服务标识, 如果主 基站 eNBl 不允许该 S1 接口建立, 则向辅基站回复 S1 建立失败 SI SETUP FAILURE消息。
步骤 204 , 主基站通过 S1接口和所述辅基站进行交互。 例如, 主基站和 辅基站之间建立 S 1接口连接, 通过 S 1接口进行数据交互。
主基站 eNBl和辅基站 eNB2之间建立了 S1接口, 后续重用 UE上下文管 理及承载管理功能, 来实现基站间的协作传输服务。
本实施例的数据交互的方法实现了由主基站触发或者 0AM配置后, 由辅 基站发起 S1接口建立请求, 从而建立了能够双向传输数据的 S1接口, 实现 了利用 S1接口在主基站和辅基站之间进行双向数据交互。 图 3和图 4为本发明第三实施例和第四实施例数据交互的方法的流程图, 实施例三和实施例四使用 X2接口来实现基站间数据交互。
如图 3所示, 第三实施例的方法包括如下步骤:
步骤 301 , 主基站向辅基站发送 X2切换请求消息, 所述 X2切换请求消 息中包括所述主基站为用户设备 UE分配的隧道地址信息;
X2切换请求 X2AP Handover reques t消息中携带主基站 eNBl 自身为 UE 分酉己的传输网各层 ( Transpor t Network Layer , TNL )地址 addres s和通用 分组无线服务 ( Genera l Packet Radio Service , GPRS ) 隧道协议 ( GPRS Tunnel ing Protocol , GTP ) [¾道端点标识 ( Tunnel Endpoint Ident if ier , TEID ) , 也可以同时携带协作服务标识, 该协作服务标识可以是基站间协作 传输 /服务标识、 基站间 CoMP标识、 基站间载波聚合服务标识、 或基站间多 流服务标识等等;
步骤 302 , 主基站 eNBl接收辅基站 eNB2返回的 X2切换响应消息; 辅基站 eNB2收到该 X2切换请求消息,得知主基站 eNBl希望辅基站 eNB2 进行对该 UE的协作传输, 如果辅基站 eNB2同意, 则向主基站 eNBl回复切换 响应 Handover reques t acknowl edge消息, 该消息可以携带基站间协作服务 标识;如果辅基站 eNB2不同意,则向主基站 eNBl回复切换准备失败 Handover preparat ion fa i lure消息;
步骤 303 , 辅基站通过 X2接口与所述主基站进行数据交互。 例如, 主基 站 eNBl和辅基站 eNB2之间建立该 UE的 X2关联和双向 GTP隧道, 从而通过 X2接口进行数据传输。
在现有技术中,在建立 X2接口时,仅建立了主基站到辅基站的 GTP隧道, 因此, X2接口仅能单向传输数据。 而在本实施例中, 通过在 X2切换请求消 息中包括主基站为用户设备 UE分配的隧道地址信息,从而能够建立辅基站到 主基站的 GTP隧道, 结合现有技术, 即建立了双向 GTP隧道, 因此, 本实施 例建立的 X2接口能够双向传输数据,从而实现主基站和辅基站之间的双向数 据交互。
优选地, 如图 3所示, 本实施例所述的方法还包括:
步骤 304 , 所述主基站更新或释放与所述 UE相关的 X2接口关联或 GTP 隧道, 并向所述辅基站发送更新或释放消息, 以便所述辅基站更新或释放所 述 UE的 X2接口关联或 GTP隧道。 通过本实施例, 当主基站更新 X2接口相关 的信息时, 辅基站也执行相应的更新流程, 这样, 主基站和辅基站关于 X2接 口的信息是一致的, 主基站和辅基站可以继续通过 X2接口进行交互。 当主基 站释放 X2接口相关的信息时, 辅基站也执行相应的释放流程, 这样, 释放出 的资源可以用于其他流程, 提高了系统性能。
当主基站 eNBl要求停止辅基站 eNB2进行对该 UE的协作服务时,会向辅 基站 eNB2发送释放消息 Handover cance l消息来释放该 UE的关联及相关 GTP 隧道。 优选地, 该消息可携带基站间协作服务标识和 /或承载标识。 如图 4所示, 第四实施例的方法包括如下步骤:
步骤 401 , 辅基站接收主基站发送的 X2切换请求消息, 所述 X2切换请 求消息中包括所述主基站为用户设备 UE分配的隧道地址信息;
X2切换请求 X2AP Handover reques t消息中携带主基站 eNBl 自身为 UE 分酉己的传输网各层 ( Transpor t Network Layer , TNL )地址 addres s和 GPRS 隧道协议 ( GPRS Tunnel ing Protocol , GTP )隧道端点标识 ( Tunnel Endpoint Ident i f ier , TEID ) , 也可以同时携带协作服务标识, 该协作服务标识可以 是基站间协作传输 /服务标识、基站间 CoMP标识、基站间载波聚合服务标识、 或基站间多流服务标识等等;
步骤 402 , 辅基站向所述主基站发送 X2切换请求响应;
辅基站 eNB2收到该 X2切换请求消息 ,得知主基站 eNBl希望辅基站 eNB2 进行对该 UE的协作传输, 如果辅基站 eNB2同意, 则向主基站 eNBl回复切换 响应 Handover reques t acknowl edge消息, 该消息可以携带基站间协作服务 标识;如果辅基站 eNB2不同意,则向主基站 eNBl回复切换准备失败 Handover preparat ion fa i lure消息;
步骤 403 , 辅基站通过 X2接口与所述主基站进行数据交互。 例如, 辅基 站 eNB2和主基站 eNBl之间建立该 UE的 X2关联和双向 GTP隧道, 从而通过
X2接口进行数据传输。
在现有技术中,在建立 X2接口时,仅建立了主基站到辅基站的 GTP隧道, 因此, X2接口仅能单向传输数据。 而在本实施例中, 通过在 X2切换请求消 息中包括主基站为用户设备 UE分配的隧道地址信息,从而能够建立辅基站到 主基站的 GTP隧道, 结合现有技术, 即建立了双向 GTP隧道, 因此, 本实施 例建立的 X2接口能够双向传输数据,从而实现辅基站和主基站之间的双向数 据交互。
优选地, 如图 4所示, 本实施例所述的方法还包括:
步骤 404 , 所述主基站更新或释放与所述 UE相关的 X2接口关联或 GTP 隧道, 所述辅基站接收所述主基站发送的更新或释放消息, 所述辅基站更新 或释放所述 UE的 X2接口关联或 GTP隧道。
当主基站 eNBl要求停止辅基站 eNB2进行对该 UE的协作服务时,会向辅 基站 eNB2发送释放消息 Handover cance l消息来释放该 UE的关联及相关 GTP 隧道。 优选地, 该消息可携带基站间协作服务标识和 /或承载标识。 实施例三和实施例四的 X2AP 切换方法, 将主基站的传输网络层 ( Transfer Network Layer , TNL )地址 addres s 和通用分组无线服务隧道 十办议 ( GPRS Tunnel l ing Protocol , GTP ) 隧道端点标只 ( Tunne l Endpo int Ident if ier , TEID )也发送给辅基站。 则可以通过 X2AP切换流程来实现主基 站和辅基站间的数据双向传输。 或者, 可以在 X2AP协议中新增 UE上下文管 理流程, 载管理流程, 与 S1AP协议相同。 图 5和图 6为本发明第五实施例和第六实施例数据交互的方法的流程图, 实施例五和实施例六可以利用 X3接口进行数据交互。
如图 5所示, 第五实施例的方法包括如下步骤:
步骤 501 , 主基站向辅基站发送建立 X3接口的请求, 其中, 所述 X3接 口具有双向数据通信的能力;
例如, X3接口是基站间协作服务接口, 可以利用 S1接口实现, 该建立 请求是从主基站 eNBl发给辅基站 eNB2的,即从主基站向辅基站发起的 X3接 口建立, 此时主基站可以看作是辅基站所连接的 "核心网设备" ;
所谓 X3接口可以是现有的其他接口, 例如利用现有的 S1接口, 也可以 是新定义的接口, 只要可以实现信息交互就可。
优选的, X3 接口建立请求可以是用于基站间协作服务的 X3 Setup Reques t , 该 X3接口建立请求中携带基站间协作服务标识, 该基站间协作服 务可以是基站间协作传输 /服务, 或者基站间 CoMP , 或者基站间载波聚合, 或者基站间多流服务, 等等;
步骤 502 , 主基站接收所述辅基站发送的建立 X3接口的响应;
如果辅基站 eNB2同意建立 X3接口,则向主基站 eNBl回复基站间协作服 务 X3接口建立响应 X3 setup response 消息, 该响应消息可以携带基站间 协作服务标识; 如果若辅基站 eNB2不同意建立 X 3接口,则回复基站间协作服务 X 3 s e t up Fa i lure消息, 同样可以携带基站间协作服务标识。
步骤 503 , 主基站通过 X3接口与所述辅基站进行数据双向交互。 例如, 主基站 eNBl和辅基站 eNB2之间建立该 UE的 X3接口,从而通过 X3接口进行 数据传输。
在本实施例中,通过主基站发送建立 X3接口的请求,从而能够建立主基 站到辅基站的 X3接口, 该 X3接口可以是现有的接口实现, 例如 S1接口, 也 可以是新定义的具有双向数据通信的能力的接口。 因此, 本实施例建立的 X3 接口能够双向传输数据, 从而实现主基站和辅基站之间的双向数据交互。 如图 6所示, 第六实施例的方法包括如下步骤:
步骤 601 , 辅基站接收主基站发送的建立 X3接口的请求, 其中, 所述 X3 接口具有双向数据通信的能力;
例如, X3接口是基站间协作服务接口, 可以利用 S1接口实现, 该建立 请求是从主基站 eNBl发给辅基站 eNB2的,即从主基站向辅基站发起的 X3接 口建立, 此时主基站可以看作是辅基站所连接的 "核心网设备" ;
所谓 X3接口可以是现有的其他接口, 例如现有的 S1接口, 也可以是新 定义的接口, 只要可以实现信息交互就可。
优选的, X3 接口建立请求可以是用于基站间协作服务的 X3 Setup Reques t , 该 X3接口建立请求中携带基站间协作服务标识, 该基站间协作服 务可以是基站间协作传输 /服务、 基站间 CoMP、 基站间载波聚合、 或基站间 多流服务, 等等;
步骤 602 , 所述辅基站向所述主基站发送建立 X3接口的响应;
如果辅基站 eNB2同意建立 X3接口,则向主基站 eNBl回复基站间协作服 务 X3接口建立响应 X3 setup response 消息, 该响应消息可以携带基站间 协作服务标识;
如果若辅基站 eNB2不同意建立 X3接口,则回复基站间协作服务 X3 setup Fa i lure消息, 同样可以携带基站间协作服务标识。
步骤 603 , 所述辅基站通过 X 3接口与所述主基站进行数据双向交互。 例 如, 辅基站 eNB2和主基站 eNBl之间建立该 UE的 X3接口, 从而通过 X3接口 进行数据传输。
在本实施例中,辅基站通过接收主基站发送建立 X3接口的请求,从而能 够建立辅基站到主基站的 X3接口, 该 X3接口可以是现有的接口实现, 例如 S1接口, 也可以是新定义的具有双向数据通信的能力的接口。 因此, 本实施 例建立的 X3接口能够双向传输数据,从而实现辅基站和主基站之间的双向数 据交互。 在上述实施例中, 都是接口建立或者切换的过程, 而接口建立或切换以 后需要利用辅基站 eNB2来进行数据交互。主基站 eNBl上不仅有 E的功能, 还可以有服务网关(Serving GW, SGW ) 的功能, 主基站 eNBl将自身分配的 SGW IP地址和 GTP TEID发送给辅基站 eNB2。
从核心网节点来看,主基站 eNBl是 UE的服务基站,核心网将该 UE的数 据及控制信令发送给主基站 eNBl , 主基站 eNBl将 UE的全部或部分数据及控 制信令转发给 eNB2。 而 UE将 UE的全部或部分上行数据发给辅基站 eNB2的, 由辅基站 eNB2将接收到的 UE的上行数据发给主基站 eNBl , 主基站 eNBl再 将上行数据转发给真正的核心网节点 SGW。
主基站 eNBl被辅基站 eNB2当做一个特殊的核心网节点, 主基站至少具 有如下功能: UE上下文管理功能、 承载管理功能和接口管理功能。
本实施例中的 X3接口,是通过主基站主动触发建立请求,辅基站响应该 请求建立的, 建立之后, 由主基站可以具有如下功能: UE上下文管理功能、 承载管理功能和接口管理功能。
此时主基站 eNBl 不会被纳入 NAS节点选择功能( NAS node select ion funct ion, 顯 SF )流程中所备选的核心网节点范围内, 即当一个 UE新接入辅 基站 eNB2 ,且该 UE不是需要由辅基站 eNB2辅助主 eNBl传输的 UE ,则在 eNB2 为该 UE选择核心网节点时, 不会将主基站 eNBl纳入备选范围内。
另外, 主基站 eNBl具有 GTP-U隧道映射 ( GTP-U tunnel mapping ) 的功 能, 实现主基站 eNBl和 SGW间的 GTP-U tunnel , 以及主基站 eNBl和辅基站 eNB2间的 GTP-U tunnel二者间的映射。
可选的,辅基站 eNB2也可以直接和 SGW进行数据交互, 而不需要通过主 基站 eNBl与 SGW进行数据交互。 当主基站 eNBl和辅基站 eNB2之间建立了 S1接口之后, 主基站 eNBl对 S1AP消息中的 TNL addres s和 GTP TEID进行 修改。 需要说明的是, 本实施例也可以作为一个独立的实施例实现。
具体的, 主基站 eNBl将接收到的辅基站 eNB2发送的辅基站的下行 TNL addres s和 GTP TEID通过匪 E发送给 SGW, 主基站 eNBl向辅基站 eNB2发送 SGW的上行 TNL addres s和 GTP TEID。 由此, 辅基站 eNB2所传输的 UE的承 载数据, 就会直接在 eNB2和 SGW之间传输了, 辅基站 eNB2将接收到的 UE发 送的上行数据发送给 SGW, 辅基站 eNB2将接收到的 SGW发送的下行数据发送 给 UE。
主基站可以和辅基站进行双向的数据传输, 由此辅基站可以利用主基站 和 SGW进行数据交互; 辅基站也可以直接和 SGW进行数据交互。 从而使得基 站间协作服务可以通过不同的基站服务不同的承载, 来提高 UE的服务质量。 最大限度的重用了现有消息。 图 7和图 8分别为本发明第七实施例和第八实施例数据交互的方法的流 程图, 上述实施例都是由主基站 eNBl来进行的与辅基站 eNB2间协作数据交 互, 第七实施例和第八实施例可以利用核心网进行辅助的数据交互。
如图 7所示, 第七本实施例的方法包括如下步骤:
步骤 701 , 匪 E接收主基站发送的第一消息, 所述第一消息用于请求辅基 站与所述主基站协同为用户设备 UE服务, 优选地, 所述第一消息中包括所述 UE的标识和所述辅基站的标识;

步骤 703 , 接收所述辅基站返回的第一响应, 所述第一响应携带所述辅 基站同意与所述主基站协同为所述 UE服务的信息;
如果辅基站 eNB2 同意该请求, 则向匪 E发送第一响应给主基站 eNBl , 该第一响应可以是基站间协作服务响应消息; 如果辅基站 eNB2 不同意该请 求, 则返回失败响应。
辅基站可以只允许部分承载的协作传输, 那么在所述基站间协作服务响 应消息中, 携带允许协作传输的承载的标识。
匪 E可以根据所述协作服务响应中携带的承载标识, 或者步骤 701 中所 述的基站间协作服务请求中携带的承载表示, 来确定每个承载在哪个基站上 传输; 进一步的, 匪 E可以根据主基站及辅基站的负载情况, UE的承载的信 息来确定每个承载在哪个基站上传输。
步骤 704 , 向所述主基站发送第二响应,以便所述主基站和所述辅基站共 同为所述 UE服务。 辅基站与匪 E之间, 以及辅基站与匪 E对应的 SGW之间为 UE标识对应的 UE的承载进行数据交互。
E发送第二响应消息给主基站 eNBl ; 若辅基站 eNB2不同意该请求, 则 返回失败响应。 MME 会按照每个承载在哪个基站上传输, 来将对应的 TNL addres s及 GTP-TEID发送给对应的节点 (主基站 eNBl或辅基站 eNB2 ) 。 辅 基站将接收到的 UE发送的上行数据发送给 SGW, SGW将接收到的 SGW发送的 下行数据发送给 UE。
本实施例的数据交互的方法利用核心网的网元匪 E的辅助数据交互, 来 实现主基站和辅基站共同为 UE服务。 利用辅基站直接和 SGW进行数据传输, 从而使得基站间协作服务可以通过不同的基站服务不同的承载,来提高 UE的 服务质量。 最大限度的重用了现有消息。 如图 8所示, 第八本实施例的方法包括如下步骤:
步骤 801 , 辅基站接收匪 E发送的第二消息, 所述第二消息用于请求所 述辅基站与主基站协同为所述 UE服务, 优选地, 所述第二消息中包括 UE的 标识;

E若同意基站间协作服务请求, 则向协作辅基站 eNB2发送第二消息, 例如基站间协作服务请求 /命令,用于请求所述辅基站与所述主基站协同为所 述 UE服务,该基站间协作服务请求 /命令中携带 UE标识和承载标识,优选的, 该基站间协作服务请求 /命令还可以携带主基站标识;
如果辅基站 eNB2同意该请求, 则向匪 E发送第一响应, 例如基站间协作 服务响应消息。 如果辅基站 eNB2不同意该请求, 则返回失败响应。
辅基站可以只允许部分承载的协作传输, 那么在所述基站间协作服务响 应消息中, 携带允许协作传输的承载的标识。
匪 E可以根据所述协作服务响应中携带的承载标识, 或者步骤 801 中所 述的基站间协作服务请求中携带的承载表示, 来确定每个承载在哪个基站上 传输; 进一步的, 匪 E可以根据主基站及辅基站的负载情况, UE的承载的信 息来确定每个承载在哪个基站上传输。
步骤 803 , 所述主基站和所述辅基站共同为所述 UE服务。 辅基站与匪 E 之间, 以及辅基站与 E对应的 SGW之间为 UE标识对应的 UE的承载进行数 据交互。
匪 E发送相关第二响应消息给主基站 eNBl ;若辅基站 eNB2不同意该请求, 则返回失败响应。 E会按照每个承载在哪个基站上传输, 来将对应的 TNL addres s及 GTP-TEID发送给对应的节点 (主基站 eNBl或辅基站 eNB2 ) 。 辅 基站将接收到的 UE发送的上行数据发送给 SGW, SGW将接收到的 SGW发送的 下行数据发送给 UE。 本实施例的数据交互的方法利用核心网的网元匪 E的辅 助数据交互, 来实现主基站和辅基站共同为 UE服务。 利用辅基站直接和 SGW 进行数据传输, 从而使得基站间协作服务可以通过不同的基站服务不同的承 载, 来提高 UE的服务质量。 最大限度的重用了现有消息。 图 9是本发明第一实施例数据交互的装置示意图, 本实施例的装置为辅 基站, 如图所示, 本实施例的数据交互的装置具体包括: 接收单元 11、 发送 单元 12和交互单元 1 3。
