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、 完整地描述, 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。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他实施例, 都属于本发明保护的范围。
实施例 1
本发明实施例提供了一种配置载波的方法, 如图 1所示, 所述方法包括:
101、 第一通信系统的服务基站接收 UE ( User Equipment, 用户设备)主 动上报的第一信令消息,所述第一信令消息包括所述 UE当前可用于所述第一 通信系统的 RF ( Radio Frequency, 射频) 能力。 所述终端能够在第一通信系 统和第二通信系统同时工作;
值得说明的是, 本发明实施例中的 UE可以扩展为多模终端 (例如手机、 平板电脑、 便携式电脑等), 能够支持多个通信系统同时通信, 所述通信系统 包括 LTE、 UMTS, GSM等。 在本发明实施例中, 不同的通信系统对应不同 通信工作模式, 可釆用不同的标准通信协议。
为了便于理解, 在本发明实施例中, 以 UE同时支持两个通信系统为例进 行说明, 将 UE支持的通信系统记作第一通信系统和第二通信系统。 其中, 所 述第一通信系统是具有载波聚合功能的系统, 例如 LTE、 UMTS等。 所述主动 上报包括不经过服务基站的触发进行的上报。 UE可用于所述第一通信系统的 RF能力发生变化包括:由于第二通信系统占用 UE的部分 RF能力导致的可用 于第一通信系统的 RF能力变化。
值得说明的是, 由于 UE能够用于第一通信系统的 RF能力发生变化后, 能够主动、 及时的向服务基站上报自身的 RF能力, 所以服务基站在获取 UE 可用于第一通信系统的 RF能力之后, 无需向第一通信系统的核心网设备记录 该 UE的 RF能力, 也就是说第一通信系统中的核心网设备无需记录 UE发生 变化的可用的 RF能力,从而能够减少网元设备之间的信令负载。例如,在 LTE 系统中, 记录 UE的 RF能力信息的网元设备为 MME ( Mobility Management Entity, 移动管理实体), 则基站无需向 MME (移动管理实体)上报 UE的 RF 能力。 需要强调的是, 不同的通信系统中记录 UE的 RF能力的核心网设备有 所不同, 此处不再赘述。
102、 所述服务基站根据所述第一信令消息将所述 UE初始可用于所述第 一通信系统的 RF能力更新为所述 UE当前可用于第一通信系统的 RF能力, 根据所述 UE当前可用于第一通信系统的 RF能力为所述 UE管理载波, 所述
管理载波包括为所述 UE进行配置、 激活、 去活载波中的至少一种操作。
值得说明的是, UE的 RF能力反应了 UE支持载波聚合的能力, 基站为 UE配置载波时需要以该 UE可用的 RF能力为依据。 对于支持多个通信系统 的 UE, 该 UE的 RF能力由该 UE支持的多个通信系统共用, 也就是说, UE 可用于某个通信系统的 RF能力是可以改变的。 而在本发明实施例中, 当 UE 的可用于第一通信系统的 RF能力发生变化时, 能够主动向第一通信系统的服 务基站上报自身的 RF能力, 以使得服务基站根据所述 UE当前可用于第一通 信系统的 RF能力为所述 UE配置载波,并对所述为 UE配置的载波进行管理, 包括对所述载波进行激活、 去活、 暂停载波的调度等操作, 无需等待服务基站 下发的关于 RF能力查询请求消息, 即不需要基于服务基站的触发上报 RF能 力。
在一个示例中, 当 UE需要利用间隙 (GAP )进行异频测量时, UE可以 在所述第一信令消息中携带 GAP指示消息,所述 GAP指示消息用于指示服务 基站在为所述 UE配置并激活的至少一个载波上配置 GAP;则所述服务基站在 接收到第一信令消息 (携带有 GAP指示消息)后, 能够在为所述 UE配置并 激活的至少一个载波上配置 GAP, 以使得所述 UE利用所述 GAP进行异频测 量。 也可以在服务基站接收到 UE发送的更新的 RF能力之后, 该基站主动为 UE配置 GAP以使得 UE能够进行异频测量。
在另一个示例中, 当 UE由服务基站切换至目标基站时, 服务基站能够向 目标基站发送当前 UE可用于第一通信系统的 RF能力, 以使得目标基站根据 所述 UE可用于第一通信系统的 RF能力为所述 UE管理载波, 所述管理载波 包括为所述 UE进行配置、 激活、 去活载波中的至少一种操作。
值得说明的是, 由于 UE向服务基站实时上报自身的 RF能力,所以当 UE 可用于所述第一通信系统的 RF能力发生变化、 需要服务基站执行为所述 UE 重新配置、 激活、 去活载波等操作中的一种或多种时, 在 UE与服务基站之间 无需重新建立 RRC ( Radio Resource Control, 无线资源控制协议)连接, 从而
能够提高数据传输的效率。
釆用本发明实施例提供的配置载波的方法, 当 UE可用于第一通信系统的 RF能力发生变化时, 能够主动的向服务基站上报变化后可用的 RF能力, 由 服务基站根据变化后的 RF能力为所述 UE配置载波并对载波进行管理, 从而 确保服务基站为 UE配置的载波能够正常工作, 提高通信质量。 实施例 2
本发明实施例提供了一种配置载波的方法, 如图 2所示, 所述方法包括: 201、 当 UE可用于第一通信系统的初始射频能力发生变化时, 主动向第 一通信系统的服务基站上报第一信令消息, 所述第一信令消息中包括所述 UE 当前可用于所述第一通信系统的 RF能力; 所述 UE能够在第一通信系统和第 二通信系统同时工作;
值得说明的是, 本发明实施例中的 UE可以扩展为多模 UE (例如手机、 平板电脑、 便携式电脑等), 能够支持多个通信系统同时通信, 所述通信系统 包括 LTE、 UMTS, GSM等。
为了便于理解, 在本发明实施例中, 以 UE同时支持两个通信系统为例进 行说明, 将 UE支持的通信系统记作第一通信系统和第二通信系统。 其中, 所 述第一通信系统是具有载波聚合功能的系统, 例如 LTE、 UMTS等。 所述主动 上报包括不经过服务基站的触发进行的上报。 UE可用于所述第一通信系统的 RF能力发生变化包括:由于第二通信系统占用 UE的部分 RF能力导致的可用 于第一通信系统的 RF能力变化。
值得说明的是, 由于 UE能够用于第一通信系统的 RF能力发生变化后, 能够主动、 及时的向服务基站上报自身的 RF能力, 所以服务基站在获取 UE 可用于第一通信系统的 RF能力之后, 无需向第一通信系统的核心网设备记录 该 UE的 RF能力, 也就是说第一通信系统中的核心网设备无需记录 UE发生 变化的可用的 RF能力,从而能够减少网元设备之间的信令负载。例如,在 LTE
系统中, 记录 UE的 RF能力信息的网元设备为 MME (移动管理实体), 则基 站无需向 MME (移动管理实体)上报 UE的 RF能力。 需要强调的是, 不同 的通信系统中记录 UE的 RF能力的核心网设备有所不同, 此处不再赘述。
202、所述 UE接收所述服务基站响应于所述第一信令消息并根据所述 UE 当前可用于第一通信系统的 RF能力执行的载波管理的信令, 所述载波管理包 括服务基站为所述 UE进行配置、 激活、 去活载波中的至少一种操作。
值得说明的是, UE的 RF能力反应了 UE支持载波聚合的能力, 基站为 UE配置载波时需要以该 UE可用的 RF能力为依据。 对于支持多个通信系统 的 UE, 该 UE的 RF能力由该 UE支持的多个通信系统共用, 也就是说, UE 可用于某个通信系统的 RF能力是可以改变的。 而在本发明实施例中, 当 UE 的可用于第一通信系统的 RF能力发生变化时, 能够主动向第一通信系统的服 务基站上报自身的 RF能力, 以使得服务基站根据所述 UE当前可用于第一通 信系统的 RF能力为所述 UE配置载波,并对所述为 UE配置的载波进行管理, 包括对所述载波进行激活、 去活、 暂停载波的调度等操作, 无需等待服务基站 下发的关于 RF能力查询请求消息, 即不需要基于服务基站的触发上报 RF能 力。
在一个示例中, 当 UE需要利用间隙 (GAP )进行异频测量时, UE可以 在所述第一信令消息中携带 GAP指示消息,所述 GAP指示消息用于指示服务 基站在为所述 UE配置并激活的至少一个载波上配置 GAP;所述 UE获取所述 服务基站基于所述 GAP指示消息在所述至少一个载波上配置的所述 GAP, 并 利用所述 GAP进行异频测量。
在另一个示例中, 当 UE由服务基站切换至目标基站时, 服务基站能够向 目标基站发送当前 UE可用于第一通信系统的 RF能力, 以使得目标基站根据 所述 UE可用于第一通信系统的 RF能力为所述 UE管理载波, 所述管理载波 包括为所述 UE进行配置、 激活、 去活载波中的至少一种操作。
值得说明的是, 由于 UE向服务基站实时上报自身的 RF能力,所以当 UE
可用于所述第一通信系统的 RF能力发生变化、 需要服务基站执行为所述 UE 重新配置、 激活、 去活载波等操作中的一种或多种时, 在 UE与服务基站之间 无需重新建立 RRC ( Radio Resource Control, 无线资源控制协议)连接, 从而 能够提高数据传输的效率。
釆用本发明实施例提供的配置载波的方法, 当 UE可用于第一通信系统的
RF能力发生变化时, 能够主动的向服务基站上报变化后可用的 RF能力, 由 服务基站根据变化后的 RF能力为所述 UE配置载波并对载波进行管理, 从而 确保服务基站为 UE配置的载波能够正常工作, 提高通信质量。 实施例 3
本发明实施例提供了一种配置载波的方法, 如图 3所示, 所述方法包括: 301、 第一通信系统的服务基站获取 UE发送的第一指示消息, 所述第一 指示消息用于表征所述 UE当前工作于第二通信系统, 其中, 所述 UE能够在 第一通信系统和第二通信系统同时工作。
值得说明的是, 本发明实施例中的 UE可以扩展为多模终端 (例如手机、 平板电脑、 便携式电脑等), 能够支持多个通信系统同时通信, 所述通信系统 包括 LTE、 UMTS, GSM等。
为了便于理解, 在本发明实施例中, 以 UE同时支持两个通信系统为例进 行说明, 将 UE支持的通信系统记作第一通信系统和第二通信系统。 其中, 所 述第一通信系统是具有载波聚合特征的系统, 例如 LTE、 UMTS等。
值得说明的是,第一通信系统的服务基站可以釆用但不限于以下方法接收 UE发送的第一指示消息:
通过 MAC ( Media Access Control, 媒体接入控制)层信令获取所述第一 指示消息; 或者
通过 RRC ( Radio Resource Control, 无线资源控制 )层信令获取所述第一 指示消息; 或者
通过物理层信令获取所述第一指示消息。
302、 所述服务基站响应于第一指示消息并获取所述 UE应用于所述第二 通信系统的 RF能力。
具体的,所述服务基站可以从第二通信系统的核心网设备获取 UE当前应 用于所述第二通信系统的 RF能力信息。 值得说明的是, 通信系统中的核心网 设备一般会记录 UE的能力 (包括 RF能力), 例如, 在 LTE系统中, 记录 UE 的能力信息的网元设备为 MME,则在本实施例中,如果第一通信系统是 LTE, 则第一通信系统的服务基站可以从第一通信系统的网元设备、或第二通信系统 的网元设备获取 UE当前应用于所述第二通信系统的 RF能力信息。 不同的通 信系统中的核心网设备之间能够进行通信。 在不同的通信系统中记录 UE 的 RF能力的核心网设备有所不同, 此处不再赘述。
可选的,所述服务基站还可以通过与第二通信系统的基站之间的接口获得 所述 UE当前应用于第二通信系统的 RF能力。
303、 所述服务基站根据所述 UE的 RF能力、 以及所述 UE应用于所述第 二通信系统的 RF能力, 确定所述 UE可用于所述第一通信系统的 RF能力, 才艮据所述可用于第一通信系统的 RF能力为所述 UE管理载波, 所述管理载波 包括为所述 UE进行配置、 激活、 去活载波中的至少一种操作。
具体的, 服务基站在为 UE配置载波之前, 会向 UE下发关于 RF能力查 询请求消息, 以获取 UE的 RF能力信息; 则服务服务基站在获取 UE应用于 第二通信系统的 RF能力之后, 能够计算出该 UE剩余可用的 RF能力, 将其 作为可用于第一通信系统的 RF能力。 当然, 可用于第一通信系统的 RF能力 可小于 UE剩余可用的 RF能力。 当 UE同时工作于两套通信系统时, 在确定 所述 UE可用于所述第一通信系统的 RF能力的过程中, 可以设置可用于第一 通信系统的 RF能力和应用于所述第二通信系统的 RF能力之和不大于 UE的 RF能力, 即不大于 UE能够支持的总 RF能力, 这样即可保持 UE正常工作在 两套通信系统上。
釆用本发明实施例提供的配置载波的方法,第一通信系统的服务基站可以 根据 UE可用于第二通信系统的 RF能力确定所述 UE可用于第一通信系统的 RF能力, 并根据可用于第一通信系统的 RF能力为所述 UE配置载波。釆用本 发明实施例提供的方法, 服务基站可以根据 UE变化后的 RF能力为所述 UE 配置载波并对载波进行管理, 确保为该 UE配置的载波能够正常工作, 提高通 信质量。 实施例 4

值得说明的是, 本发明实施例中的 UE可以扩展为多模终端 (例如手机、 平板电脑、 便携式电脑等), 能够支持多个通信系统同时通信, 所述通信系统 包括 LTE、 UMTS, GSM等。
为了便于理解, 在本发明实施例中, 以 UE同时支持两个通信系统为例进 行说明, 将 UE支持的通信系统记作第一通信系统和第二通信系统。 其中, 第一通信系统是具有载波聚合特征的系统, 例如 LTE、 UMTS等。
具体的, 服务基站可以将第一载波挂起, 即暂停为所述 UE调度第一载波 上的资源。
402、 当所述服务基站接收到 UE发送的第二 MAC CE、 且所述第一载波 没有被所述服务基站去活时, 恢复在所述第一载波上为所述 UE调度资源, 其 中, 所述第二 MAC CE用于表征所述 UE在所述第一载波上能够传输数据。
本发明实施例提供的配置载波的方法,服务基站能够根据 UE发送的指示 消息暂停为所述 UE调度第一载波上的资源; 当 UE能够在第一载波上传输数 据时, 能够根据 UE的指示消息恢复在第一载波上为 UE调度资源。 釆用本实 施例提供的方法, 在基站为 UE配置的载波被挂起时, 能够在满足激活条件的 情况下恢复第一载波上资源的调度, 从而能够保证用户数据的吞吐量。 实施例 5
本发明实施例提供了一种配置载波的方法, 如图 5所示, 所述方法包括:
501、 当 UE在第一载波上需要停止传输数据时, 向第一通信系统的服务 基站发送第一 MAC CE,所述第一 MAC CE用于指示服务基站暂停为所述 UE 调度第一载波上的资源;所述终端能够在第一通信系统和第二通信系统同时工 作。 其中, UE的第一载波原来工作于第一通信系统, 当前需要被其它通信系 统占用,如被第二通信系统占用, 则需要停止向第一通信系统的服务基站传输 数据, 则 UE发送所述第一 MAC CE, 触发服务基站暂停资源调度。
值得说明的是, 本发明实施例中的 UE可以扩展为多模终端 (例如手机、 平板电脑、 便携式电脑等), 能够支持多个通信系统同时通信, 所述通信系统 包括 LTE、 UMTS, GSM等。
为了便于理解, 在本发明实施例中, 以 UE同时支持两个通信系统为例进 行说明, 将 UE支持的通信系统记作第一通信系统和第二通信系统。 其中, 第一通信系统是具有载波聚合特征的系统, 例如 LTE、 UMTS等。
具体的, 服务基站可以将第一载波挂起, 即暂停为所述 UE调度第一载波 上的资源。
502、 当所述 UE在所述第一载波上能够传输数据时, 向所述服务基站发 送第二 MAC CE, 所述第二 MAC CE用于指示所述服务基站恢复在所述第一 载波上为所述 UE调度资源, 以使得所述 UE通过所述第一载波与所述服务基 站进行通信。

本发明实施例提供了一种配置载波的方法, 如图 6所示, 所述方法包括: 601、 UE向第一通信系统的服务基站发送自身的 RF能力, 以便于所述服 务基站根据所述 UE的 RF能力为所述 UE配置载波。
值得说明的是, 本发明实施例中的 UE可以扩展为多模终端 (例如手机、 平板电脑、 便携式电脑等), 能够支持多个通信系统同时通信, 所述通信系统 包括 LTE、 UMTS, GSM等。
为了便于理解, 在本发明实施例中, 以 UE同时支持两个通信系统为例进 行说明, 将 UE支持的通信系统记作第一通信系统和第二通信系统。 其中, 第一通信系统是具有载波聚合特征的系统, 例如 LTE、 UMTS等。
为了便于理解, 本发明实施例以所述 UE为双模双待终端为例进行说明, 将 UE支持的通信系统标记为第一通信系统和第二通信系统。
602、服务基站根据所述 UE的 RF能力为所述 UE配置第一载波, 向所述
UE发送第一载波的激活指示消息,以指示所述 UE对所述第一载波进行激活。
值得说明的, 当所述 UE可用于第一通信系统的 RF能力较强、且所述 UE 的业务数据量较大时, 所述服务基站也可以为所述 UE配置多个载波。
603、 当所述 UE接收到所述第一载波的激活指示消息, 但由于第二通信 系统占用了所述 UE的 RF能力, 导致所述 UE无法激活所述第一载波时, 向 所述服务基站发送第一 MAC CE, 所述第一 MAC CE用于表征 UE在第一载
波上停止传输数据。
值得说明的是, 步骤 603也可以是如下场景:
UE接收到所述第一载波的激活指示消息, 激活第一载波;
在通过第一载波与服务基站进行通信的过程中,由于第二通信系统占用了 所述 UE的 RF能力, 导致所述 UE无法激活所述第一载波时, 向所述服务基 站发送第一 MAC CE。
在一个示例中, UE可以根据自身可用于第一通信系统的 RF能力确定建 议服务基站激活的载波, 将其标记为第二载波, 并在所述第一 MAC CE中携 带第二载波的标识, 以使得服务基站接收到第一 MAC CE (携带有第二载波标 识)后, 为 UE配置所述第二载波并激活第二载波。 在激活所述第二载波后, 所述 UE可以在所述第二载波接收所述服务基站为该 UE调度的资源。

具体的, 服务基站可以将第一载波暂时挂起, 以暂停为 UE调度第一载波 上的资源。
可选的,服务基站也可以选择去活所述第一载波, 则所述服务基站需要向 所述 UE发送第一载波的去活信令, 以指示所述 UE无需激活第一载波。
值得说明的是, 当所述 UE从服务基站切换至目标基站时, 服务基站可以 向目标基站发送第一载波的标识, 以通知所述目标基站 UE在第一载波上无法
传输数据。
605、 当第二通信系统停止工作并释放了所占用的 RF 能力时, 所述 UE 向服务基站发送第二 MAC CE, 所述第二 MAC CE用于表征 UE在第一载波 上能够传输数据。
606、 当服务基站接收所述 UE发送的第二 MAC CE、 且所述第一载波没 有被所述服务基站去活时, 恢复在所述第一载波上为 UE调度资源, 通过所述 第一载波与 UE进行通信。
具体的, 所述 UE可以直接激活所述第一载波, 也可以由所述服务基站根 据需要决定是否重新发送激活命令。 例如: 当所述 UE请求的业务数据量较大 时, 所述服务基站可以向所述 UE重新发送激活命令, 以指示所述 UE激活数 据传输能力较强的载波。
本发明实施例提供的配置载波的方法也可以实现如下方案:
当所述 UE已经激活第一载波与第一通信系统进行通信时,如果第二通信 系统需要占用第一通信系统已经使用的 RF能力 (例如 UE与第二通信系统之 间的业务的优先级较高), 则 UE可以强制让出当前服务于第一通信系统的 RF 能力, 同时主动挂起在该 RF上工作的第一载波, 并及时通知第一通信系统的 服务基站挂起第一载波。 在第二通信系统停止工作后, UE可以直接激活第一 载波与第一通信系统进行通信, 或者由基站决定是否继续激活第一载波(当 UE的业务量较小时, 基站可以继续激活第一载波; 当 UE的业务量较大时, 基站可以重新为 UE配置载波)。
本发明实施例提供的配置载波的方法, 当 UE的 RF能力被其他通信系统 占用, 导致无法在第一载波上传输数据时, 能够通知服务基站暂停第一载波上 的资源调度; 当 UE的 RF能力能够在第一载波上传输数据时, 能够向服务基 站发送指示消息以恢复第一载波上资源的调度。釆用本实施例提供的方法,在 UE满足激活条件的情况下能够恢复第一载波上资源的调度, 从而能够保证用 户数据的吞吐量。
