Description

无线承载配置方法及装置 技术领域 本发明涉及通信领域， 具体而言， 涉及一种无线承载（Radio Bearer, 简称为 RB) 配置方法及装置。 背景技术 非鉴权时延 （例如， 附着 （ATTACH) 时延） 是一种用于评估运营商服务质量的 关键绩效指标 （Key Performance Indicator, 简称为 KPI) 指标。 图 1是根据相关技术 中的长期演进 （Long Term Evolution, 简称为 LTE) ATTACH时延计算方法示意图， 如图 1所示， 按照协议规定， ATTACH时延是指用户设备 （User Equipment, 简称为 UE)侧发起随机接入信道前导 （RACH Preamble) 为起始点， 到 UE发送 ATTACH完 成（ATTACH Complete)为结束点之间的时间差。 如图 1所示的 ATTACH流程中未示 出网络存储技术（Network Storage Technology, 简称为 NAS)鉴权， 未示出 NAS安全 模式， 示出了 UE能力查询。 但是， 目前的 ATTACH时延较长， 直接影响了运营商的 KPI指标， 使得用户体验 度较低。 针对相关技术中 ATTACH时延较长的问题， 目前尚未提出有效的解决方案。 发明内容 本发明实施例提供了一种无线承载配置方案， 以至少解决相关技术中 ATTACH时 延较长的问题。 根据本发明实施例， 提供了一种 RB配置方法， 包括： 基站接收 UE发送的消息， 其中， 所述消息用于指示所述基站配置 RB; 所述基站在完成配置所述 RB之前向所述 UE发送所述消息的响应消息。 优选地， 所述基站的控制面接收 UE发送的消息， 其中， 所述消息用于指示所述 基站配置 RB; 所述控制面向所述 UE发送所述消息的响应消息； 所述基站的控制面向 所述基站的用户面发送命令， 所述命令用于指示所述用户面配置所述 RB。 优选地，所述基站配置的所述 RB包括以下至少之一： 信令无线承载 1 ( Signalling
Radio Bearerl，简称为 SRBl )、信令无线承载 2( Signalling Radio Bearer2,简称为 SRB2) 和数据无线承载 （Data Radio Bearer, 简称为 DRB)。 优选地，在所述 RB为 SRB1的情况下，所述基站接收所述 UE发送的所述消息为 RRC连接请求消息， 所述响应消息为无线资源控制 （Radio Resource Control, 简称为 RRC) 连接建立消息。 优选地， 在所述 RB为 SRB2和 DRB的情况下， 所述基站接收所述 UE发送的所 述消息为 UE能力消息， 所述响应消息为 RRC连接重配置消息。 优选地， 在所述基站在完成配置所述 RB之前向所述 UE发送所述消息的响应消 息之后， 还包括： 所述基站判断配置所述 RB是否成功； 在判断结果为配置失败的情 况下， 所述基站发起异常回滚， 其中， 所述异常回滚用于所述基站重新接收所述 UE 发送的所述消息。 优选地， 所述基站判断配置所述 RB是否成功包括： 在所述基站的控制面接收来 自所述基站的用户面的配置所述 RB的配置响应为失败的情况下， 认为所述判断结果 为配置失败； 或者， 在所述基站的控制面在预定时间内未接收到来自所述基站的用户 面的配置所述 RB的配置响应的情况下， 认为所述判断结果为配置失败。 根据本发明的另一实施例， 提供了一种 RB配置装置， 位于基站中， 包括： 接收 模块， 设置为接收 UE发送的消息， 其中， 所述消息用于指示所述基站配置 RB; 发送 模块， 设置为在完成配置所述 RB之前向所述 UE发送所述消息的响应消息。 优选地， 所述接收模块设置为所述基站的控制面接收 UE发送的消息， 其中， 所 述消息用于指示所述基站配置 RB;所述发送模块设置为所述控制面向所述 UE发送所 述消息的响应消息； 所述装置还包括， 第二发送模块， 设置为所述控制面向所述基站 的用户面发送命令， 所述命令用于指示所述用户面配置所述 RB。 优选地， 所述装置还包括： 判断模块， 设置为判断配置所述 RB是否成功； 回滚 模块， 设置为在所述判断模块的判断结果为配置失败的情况下， 发起异常回滚， 其中， 所述异常回滚用于重新接收所述 UE发送的所述消息。 通过本发明， 采用基站接收 UE发送的消息， 其中， 该消息用于指示基站配置无 线承载 （Radio Bearer, 简称为 RB); 基站在完成配置 RB之前向 UE发送该消息的响 应消息。 解决了相关技术中 ATTACH时延较长的问题， 进而缩短了 ATTACH时延。 附图说明 此处所说明的附图用来提供对本发明的进一步理解， 构成本申请的一部分， 本发 明的示意性实施例及其说明用于解释本发明， 并不构成对本发明的不当限定。 在附图 中： 图 1是根据相关技术中的长期演进 ATTACH时延计算方法示意图； 图 2是根据本发明实施例的无线承载配置方法的流程图； 图 3是根据本发明实施例的无线承载配置装置的结构框图； 图 4是根据本发明实施例的无线承载配置装置的优选结构框图一； 图 5是根据本发明实施例的无线承载配置装置的优选结构框图二； 图 6是根据本发明优选实施例一的正常流程的示意图； 图 7是根据本发明优选实施例一的异常流程一的示意图； 图 8是根据本发明优选实施例一的异常流程二的示意图； 图 9是根据本发明优选实施例二的正常流程的示意图； 图 10是根据本发明优选实施例二的异常流程一的示意图； 图 11是根据本发明优选实施例二的异常流程二的示意图。 具体实施方式 下文中将参考附图并结合实施例来详细说明本发明。 需要说明的是， 在不冲突的 情况下， 本申请中的实施例及实施例中的特征可以相互组合。 从图 1 的流程图中可以看出， 在 ATTACH过程中， 演进的基站 （eNodeB, 简称 为 E B) 在建立 RB (包括信令无线承载 1 ( Signalling Radio Bearerl， 简称为 SRB1 )、 SRB2和数据无线承载（Data Radio Bearer, 简称为 DRB) )时， 需要同步等待 RB建立 完成才发起后续信令流程， 也就是说 RB的配置与空口信令是串行流程， 需要等待 RB 配置完成后才能向 UE发送空口信令。 这种方式对 ATTACH造成了一定的影响， 降低 了用户体验度。 本实施例提供了一种无线承载 RB配置方法， 图 2是根据本发明实施例的无线承 载配置方法的流程图， 如图 2所示， 该方法包括如下步骤： 步骤 S202, 基站接收 UE发送的消息， 其中， 该消息用于指示基站配置 RB; 步骤 S204, 基站在完成配置 RB之前向 UE发送该消息的响应消息。 本实施例通过上述步骤， 通过在基站完成配置 RB之前向 UE发送响应消息， 使 得 UE可以在基站尚未完成配置 RB的同时进行后续流程， 相比相关技术中在基站配 置 RB完成后再向 UE发送响应消息的方式， 使得 UE进行后续的流程与基站配置 RB 的过程是并行处理的，解决了相关技术中 ATTACH时延较长的问题，缩短了 ATTACH 时延。 进而能够改善运营商的 KPI指数。 优选地， 可以由基站的控制面接收 UE发送的上述消息， 然后， 由控制面向 UE 发送该消息的响应消息， 基站的控制面再向基站的用户面发送命令， 该命令用于指示 用户面配置 RB。 需要说明的是， 在 LTE系统中， 基站配置 RB的过程可以在基站的 用户面进行， 向 UE发送响应消息的过程可以在基站的控制面进行， 但是在其他系统 中， 上述配置 RB的过程以及与 UE进行通信的过程并不一定在上述的层面进行。 优选地，基站配置的 RB可以是 SRB1 , 也可以是 SRB2和 DRB，或者其他的 RB。 例如，当该 RB为 SRB1时，基站接收 UE发送的消息为无线资源控制（Radio Resource Control, 简称为 RRC)连接请求消息（RrcConnectionRequest), 响应消息为 RRC连接 建立消息 （RrcConnectionSetup)。 再例如， 当该 RB为 SRB2和 DRB ( SRB2&DRB) 的情况下， 基站接收 UE发送的消息为 UE能力消息 （UeCapabilitylnformation), 响应 消息为 RRC连接重配置消息 （RrcConnectionReconfig)。 考虑到基站在配置 RB时有可能配置失败， 因此作为一种优选实施方式， 在步骤 S204之后， 基站可以判断配置 RB是否成功； 在判断结果为配置失败的情况下， 基站 可以发起异常回滚， 其中， 该异常回滚用于基站重新接收 UE发送的消息， 例如， 可 以回滚至重新发起步骤 S202。 通过这种方式， 提高了方案的可靠性。 在实施过程中， 基站判断配置 RB失败的方式可以有很多种， 在本实施例中提供 了两种优选实施方式。 方式一： 在基站的控制面接收来自基站的用户面的配置 RB的 配置响应为失败的情况下， 认为判断结果为配置失败； 方式二： 在基站的控制面在预 定时间内未接收到来自基站的用户面的配置 RB的配置响应的情况下， 认为判断结果 为配置失败。 通过上述方式， 提高了异常回滚操作的灵活性。 对应于上述方法， 在本实施例中还提供了一种无线承载 RB配置装置， 位于基站 中， 该装置用于实现上述实施例及优选实施方式， 已经进行过说明的不再赘述。 如以 下所使用的， 术语"模块"可以实现预定功能的软件和 /或硬件的组合。 尽管以下实施例 所描述的装置较佳地以软件来实现， 但是硬件， 或者软件和硬件的组合的实现也是可 能并被构想的。 图 3是根据本发明实施例的无线承载配置装置的结构框图， 如图 3所示， 该装置 包括： 接收模块 32和发送模块 34， 下面对各个模块进行详细说明。 接收模块 32， 设 置为接收 UE发送的消息， 其中， 该消息用于指示基站配置无线承载； 发送模块 34， 与接收模块 32相连， 设置为在完成配置 RB之前向 UE发送该消息的响应消息。 本实施例通过上述装置， 通过在基站完成配置 RB之前向 UE发送响应消息， 使 得 UE可以在基站尚未完成配置 RB的同时进行后续流程， 相比相关技术中在基站配 置 RB完成后再向 UE发送响应消息的方式， 使得 UE进行后续的流程与基站配置 RB 的过程是并行处理的，解决了相关技术中 ATTACH时延较长的问题，缩短了 ATTACH 时延。 进而能够改善运营商的 KPI指数。 图 4是根据本发明实施例的无线承载配置装置的优选结构框图一， 如图 4所示， 接收模块 32还可以设置为基站的控制面接收 UE发送的消息， 其中， 该消息用于指示 基站配置 RB; 发送模块 34还可以设置为控制面向 UE发送消息的响应消息； 上述装 置还可以包括， 第二发送模块 42， 与发送模块 34相连， 设置为控制面向基站的用户 面发送命令， 该命令用于指示用户面配置 RB。 图 5是根据本发明实施例的无线承载配置装置的优选结构框图二， 如图 5所示， 该装置还可以包括：判断模块 52，与发送模块 34相连，设置为判断配置 RB是否成功； 回滚模块 54， 与判断模块 52相连， 设置为在判断模块 52的判断结果为配置失败的情 况下， 发起异常回滚， 其中， 该异常回滚用于重新接收 UE发送的上述消息。 以下结合优选实施例进行说明， 下述优选实施例结合了上述实施例及其优选实施 方式。 在下述优选实施例中提供了一种减少接入时延的方法与装置。通过在 LTE系统内 将 RB(Radio bearer)配置与业务信令由串行转为并行， 从而减少接入时延， 进而提高用 户体验。 在下述优选实施例中， 当 E B接收到 UE的相关信令需要配置 RB时， E B不需 要等待 RB配置完成就直接发起后续信令流程， 从而可以有效降低由于 RB配置同步 等待所造成的 ATTACH时延过大问题， 提高了用户体验度。 优选实施例一 图 6是根据本发明优选实施例一的正常流程的示意图， 如图 6所示， 该正常流程 包括如下步骤： 步骤 S602， E B控制面接收到 UE在上行公共控制信道（UpLink Common Control Channel, 简称为 ULCCCH) 上发送的 RrcConnectionRequest消息。 步骤 S604， ENB 控制面通过下行公共控制信道 （DownLink Common Control Channel, 简称为 DLCCCH) 给 UE发送 RrcConnectionSetup消息。 步骤 S606， ENB控制面给用户面配置 SRB1。 步骤 S608， 用户面配置完成后给控制面回复 SRB1配置完成消息。 步骤 S610， E B控制面接收到 UE在 ULCCCH上发送的 RRC连接建立完成 ( RrcConnectionSetupComplete ) 消息。 步骤 S612, 进行后续流程。 图 7是根据本发明优选实施例一的异常流程一的示意图， 如图 7所示， 该异常流 程包括如下步骤： 步骤 S702， E B控制面接收到 UE在 ULCCCH上发送的 RrcConnectionRequest 消息。 步骤 S704， E B控制面通过 DLCCCH给 UE发送 RrcConnectionSetup消息。 步骤 S706， E B控制面给用户面配置 SRB1。 步骤 S708, 用户面配置完成后给控制面回复 SRB1配置失败消息。 步骤 S710， E B发起回滚。 图 8是根据本发明优选实施例一的异常流程二的示意图， 如图 8所示， 该异常流 程包括如下步骤： 步骤 S802， ENB控制面接收到 UE在 ULCCCH上发送的 RrcConnectionRequest 消息。 步骤 S804， ENB控制面通过 DLCCCH给 UE发送 RrcConnectionSetup消息， 并 设置等待应答定时器 1。 步骤 S806， E B控制面给用户面配置 SRB1。 步骤 S808, 用户面配置完成后给控制面回复 SRB1配置完成消息。 步骤 S810, 控制面定时器 1超时， 发起异常回滚流程， 释放资源。 优选实施例二 图 9是根据本发明优选实施例二的正常流程的示意图， 如图 9所示， 该正常流程 包括如下步骤： 步骤 S902， E B控制面接收到 UE在 ULCCCH上发送的 RrcConnectionRequest 消息之后， ENB 控制面接收到 UE 在 ULDCCH 上发送的 UE 能力消息 ( UeCapabilitylnformation ) 消息。 步骤 S904， E B 控制面通过 DLCCCH 给 UE 发送 RRC 连接重配置 ( RrcConnectionReconfig ) 消息。 步骤 S906， E B控制面给用户面配置 SRB2&DRB。 步骤 S908, 用户面配置完成后给控制面回复配置完成消息。 步骤 S910， E B控制面接收到 UE在 ULCCCH上发送的 RrcConnectionReconfig Complete消息。 步骤 S912， 进行后续流程。 图 10是根据本发明优选实施例二的异常流程一的示意图， 如图 10所示， 该异常 流程包括如下步骤： 步骤 S1002，E B控制面接收到 UE在 ULDCCH上发送的 UeCapabilitylnformation 消息。 步骤 S1004, E B控制面通过 DLCCCH给 UE发送 RrcConnectionReconfig消息。 步骤 S1006, E B控制面给用户面配置 SRB2&DRB。 步骤 S1008, 用户面配置完成后给控制面回复配置失败消息。 步骤 S1010, E B发起异常回滚， 不处理后面的重配完成消息。 图 11是根据本发明优选实施例二的异常流程二的示意图， 如图 11所示， 该异常 流程包括如下步骤： 步骤 S1102，E B控制面接收到 UE在 ULDCCH上发送的 UeCapabilitylnformation 消息。 步骤 S1104, E B控制面通过 DLCCCH给 UE发送 RrcConnectionReconfig消息。 步骤 S1106, E B控制面给用户面配置 SRB2&DRB。 步骤 S1108, 用户面配置完成后给控制面回复配置完成消息。 步骤 S1110, E B RRC建立定时器 1超时， E B发起回滚， 释放资源。 在另外一个实施例中， 还提供了一种软件， 该软件用于执行上述实施例及优选实 施例中描述的技术方案。 在另外一个实施例中， 还提供了一种存储介质， 该存储介质中存储有上述软件， 该存储介质包括但不限于光盘、 软盘、 硬盘、 可擦写存储器等。 从以上的描述中， 可以看出， 本实施例通过在基站完成配置 RB之前向 UE发送 响应消息， 使得 UE可以在基站尚未完成配置 RB的同时进行后续流程， 相比相关技 术中在基站配置 RB完成后再向 UE发送响应消息的方式，使得 UE进行后续的流程与 基站配置 RB的过程是并行处理的， 解决了相关技术中 ATTACH时延较长的问题， 缩 短了 ATTACH时延。 进而能够改善运营商的 KPI指数。 显然， 本领域的技术人员应该明白， 上述的本发明的各模块或各步骤可以用通用 的计算装置来实现， 它们可以集中在单个的计算装置上， 或者分布在多个计算装置所 组成的网络上， 可选地， 它们可以用计算装置可执行的程序代码来实现， 从而， 可以 将它们存储在存储装置中由计算装置来执行， 并且在某些情况下， 可以以不同于此处 的顺序执行所示出或描述的步骤， 或者将它们分别制作成各个集成电路模块， 或者将 它们中的多个模块或步骤制作成单个集成电路模块来实现。 这样， 本发明不限制于任 何特定的硬件和软件结合。 以上所述仅为本发明的优选实施例而已， 并不用于限制本发明， 对于本领域的技 术人员来说， 本发明可以有各种更改和变化。 凡在本发明的精神和原则之内， 所作的 任何修改、 等同替换、 改进等， 均应包含在本发明的保护范围之内。
