Description

一种无线资源控制连接重配置失败的处理方法及*** 技术领域
本发明涉及通信领域, 尤其涉及一种长期演进 ( LTE , Long Term Evolution ) 中无线资源控制 (RRC, Radio Resource Control )连接重配置失 败的处理方法及***。 背景技术
一个富有生命力的移动通信***, 能够随着需求的增长而不断增强, 为用户提供更高的数据速率, 为网络提供更好的覆盖、 更大的容量。 出于 这样的考虑和技术的驱动, 第三代合作伙伴计划 (3GPP, 3rd Generation Partnership Project )在 2004年 12月启动了无线接入网长期演进项目 LTE, 演进的接入技术 E-UTRA和演进的接入网络 E-UTR AN,以及面向全网际协 议(IP, Internet Protocol ) 的分组域核心网演进项目***结构演进( SAE, System Architecture Evolution ) , 希望通过从无线接口到核心网络的持续演 进和增强, 为运营商和用户不断增长的需求提供更好的支持, 在今后 10年 甚至更长的时间,一直保持在移动通信领域的技术先发优势。其中, E-UTRA 指演进的通用陆地无线接入技术 ( Evolved-UTRA , Evolved Universal Terrestrial Radio Access ) ; E-UTRAN 指演进的通用陆地无线接入网 ( Evolved-UTR AN , Evolved Universal Terrestrial Radio Access Network ) 。
LTE是一种以正交频分复用 (OFDM, Orthogonal Fre-quency Division Multiplexing ) /单载波频分复用 (SC-FDMA , Single Carrier- Frequency Division Multiple Access )为核心的技术, 3GPP LTE项目的主要性能目标包 括以下内容:
一、 在 20MHz频谱带宽能够提供下行 100Mbps、 上行 50Mbps的峰值 速率;
二、 改善小区边缘用户的性能;
三、 提高小区容量;
四、 降低***延迟, 用户平面内部单向传输时延低于 5ms, 控制平面 从睡眠状态到激活状态迁移时间低于 50ms, 从驻留状态到激活状态的迁移 时间小于 100ms;
五、 支持 lOOKm半径的小区覆盖;
六、 能够为 350Km/h高速移动用户提供 >100kbps的接入服务; 七、 支持成对或非成对频谱, 并可灵活配置 1.25 MHz到 20MHz多种 带宽。
为了达到上述目标, 各项技术正在研究, 相关规范正在制定中。 目前, 针对 3GPP RRC协议而言 , 在 RRC连接重配置过程中 , 由于任何一部分配 置失败就会导致 RRC连接重配置的失败, 因此, 需要对 RRC连接重配置 过程进行改进。 以下具体阐述。
现有 3GPP RRC协议中描述了 RRC连接重配置过程, 如果 RRC连接 重配置成功完成, 则其实现流程如图 1所示, 包括以下步骤:
步骤 101、 处于连接态的用户设备 ( UE , User Equipment ) , 在业务过 程中, 如果需要修改、 释放 RRC连接, 或者执行切换, 或者配置、 修改测 量等, E-UTRAN下发 RRC连接重配置消息给 UE。
步骤 102、 UE根据 RRC连接重配置消息中的相关字段处理。
这里, RRC连接重配置消息中包括的相关字段分为以下几项内容, 以 及针对字段相对应的处理如下所示:
一: 如果 RRC连接重配置消息中包含无线资源配置部分, 则根据消息 内容重配置无线承载、 数据无线承载、 传输信道、 物理信道。
二: 如果 RRC连接重配置消息中包含 UE相关信息部分, 则把新的小 区级无线网络临时标识赋值给 UE。
三:如果 RRC连接重配置消息中包含移动控制信息部分,则执行切换。 四: 如果 RRC连接重配置消息中包含非接入层专用信息部分, 则把此 字段部分传递给上层。
五: 如果 RRC连接重配置消息中包含测量相关信息部分, 则执行测量 配置部分修改。
需要指出的是: 如果上述的五项都能成功执行后, 则 UE会发送 RRC 连接重配置完成消息给 E-UTRAN, 以完成 RRC连接重配置; 如果上述五 项中任何一项在执行过程中异常, 则 RRC连接重配置过程失败, 如图 2所 示, 该失败流程包括以下步骤:
步骤 201、处于连接态的 UE,在业务过程中,如果需要修改、释放 RRC 连接, 或者执行切换, 或者配置、 修改测量等, E-UTRAN下发 RRC连接 重配置消息给 UE。
步骤 202、 UE根据 RRC连接重配置消息中相关字段处理。
这里, 如果对任何一项执行时异常, 恢复到收到 RRC连接重配置消息 前的配置, 同时, UE发送 RRC连接重配置失败消息给 E-UTRAN。
而且,对于 RRC连接重配置失败消息,现有协议中是这么描述的: RRC 连接重配置失败消息是一条不包含任何诊断信息的消息, 比如, 甚至没有 标识是哪个部分配置失败导致的。
综上所述,分析上述的现有失败流程可知,在 RRC连接重配置过程中, 釆用现有协议存在的问题为: RRC连接重配置消息涉及参数众多, 如果任 何一个参数出错, 就需要恢复到收到 RRC连接重配置消息前的配置, 导致 RRC连接重配置过程实现起来很复杂, 同时也违背了网络发起重配置操作 的本意。 然而现有的协议并没有考虑到这个问题, 有待于进一步完善。 发明内容
有鉴于此, 本发明的主要目的在于提供一种 RRC连接重配置失败的处 理方法及***, 对 RRC连接重配置过程中, 由于任何一部分配置失败所导 致连接重配置流程失败时的后续处理, 进行了完善, 降低了 RRC连接重配 置过程的实现复杂度。
为达到上述目的, 本发明的技术方案是这样实现的:

图 1为现有 RRC连接重配置过程中重配置成功的实现流程示意图; 图 2为现有 RRC连接重配置过程中重配置失败的实现流程示意图; 图 3为本发明方法的实现流程示意图。 具体实施方式
本发明的基本思想是: UE收到来自于网络侧的 RRC连接重配置消息 后, 执行 RRC连接重配置消息中的各参数对应的配置; 根据执行到的当前 参数的配置执行情况,执行相对应的维持当前配置、或恢复到 UE收到 RRC 连接重配置消息前配置的处理。
下面结合附图对技术方案的实施作进一步的详细描述。
如图 3所示, 一种 RRC连接重配置失败的处理方法, 该方法包括以下 步骤:
步骤 301、 UE接收到来自于网络侧的 RRC连接重配置消息后, 执行 RRC连接重配置消息中的各参数对应的配置。
这里, 在执行时, UE是按照事先与网络侧的顺序执行的约定, 顺序执 行 RRC连接重配置消息中的各参数对应的配置。
步骤 302、根据执行到的当前参数的配置执行情况,执行相对应的维持 当前配置、 或恢复到 UE收到 RRC连接重配置消息前的配置。
这里, 步骤 302的具体处理过程包括以下两种情况, 以下分别阐述。 第一种情况: 当执行到的当前参数为非物理层参数时, 在非物理层参 数配置失败导致 RRC连接重配置失败的情况下, UE维持当前非物理层参 数的配置, 即: UE无需恢复到收到 RRC连接重配置消息前的非物理层参 数的配置。 第二种情况: 当执行到的当前参数为物理层参数时, 在物理层参数配 置失败导致 RRC连接重配置失败时, UE恢复到收到 RRC连接重配置消息 前的物理层参数的配置; 或者, UE维持当前物理层参数的配置。
就以上第一种情况而言,具体来说,在非物理层参数配置失败导致 RRC 连接重配置失败的情况下, 步骤 302还包括: UE维持当前非物理层参数的 配置的同时, 根据当前非物理层参数配置失败的操作设置失败原因值。
这里, 设置失败原因值之后还包括: 将失败原因值封装到 RRC连接重 配置失败消息中, 并发送给网络侧; 网络侧收到 RRC连接重配置失败消息 后, 根据顺序执行的约定和失败原因值执行后续的判决处理。
其中, 判决处理包括: 判决是否重新建立 RRC连接、 修改承载 /测量参 数、 或者直接释放 RRC连接。
就以上第二种情况而言, 具体来说, 在物理层参数配置失败导致 RRC 连接重配置失败的情况下, 步骤 302还包括: UE维持 /恢复当前物理层参数 的配置的同时, 根据当前物理层参数配置失败的操作设置失败原因值。
这里, 设置失败原因值之后还包括: 将失败原因值封装到 RRC连接重 配置失败消息中, 并发送给网络侧; 网络侧收到 RRC连接重配置失败消息 后, 根据顺序执行的约定和失败原因值执行后续的判决处理。
其中, 判决处理包括: 判决是否重新建立 RRC连接、 修改承载 /测量参 数、 或者直接释放 RRC连接。
这里, 当 UE物理层参数的配置恢复失败、 或超过最大重传次数导致 RRC连接重配置失败消息发送失败时, 步骤 302后还包括: UE释放 RRC 连接的相关无线资源, 直接返回空闲态。
其中, 空闲态时 UE执行小区选择过程, 驻留到相对应的小区。
综上所述, 本发明主要包括以下内容:
本发明所要解决的技术问题是针对当前协议, 用于解决 RRC连接重配 置由于部分配置失败, 导致此流程失败的后续处理。
网络侧下发 RRC连接重配置消息, 目的是为了修改无线资源, 执行切 换, 修改测量等, 涉及到的参数、 操作较多, 过程复杂。 因此, 由于其中 某一配置项异常导致此过程失败, 恢复到收到消息前的配置操作繁瑣, 对 于实现重配置过程本身, 也是没有意义的。 基于此, 本发明提供了一种简 化的解决方案, 包括以下内容:
一、 UE收到 RRC连接重配置消息, 顺序执行 RRC连接重配置消息中 涉及到的各重配置项。
二、 如果执行到某一配置项时失败, 维持当前配置, 无需恢复到收到 RRC连接重配置消息前的配置, 同时根据具体操作设置失败原因值。
三、 UE携带失败原因值发送 RRC连接重配置失败消息给网络侧。 四、 网络侧收到 RRC连接重配置失败消息, 根据顺序执行的约定及失 败原因值, 明确了 RRC连接重配置的执行情况及失败情况, 决定是否重新 建立 RRC连接, 修改承载、 测量参数, 还是直接释放 RRC连接等的判决 处理。
进一步地, 上述解决方案中存在一种特殊情况, 即: 重配置是由于物 理层参数修改失败的情况, 由于没有恢复到收到 RRC连接重配置消息前的 配置, 可能由于 UE/演进的基站(eNB , Evolved NodeB ) 中一些不同配置, UE试图通过底层发送 RRC连接重配置失败消息。 对于涉及到物理层参数 所导致的重配置失败的情况, 釆用以下两种解决方法之一:
第一种、 对于涉及物理层参数配置的情况, 执行特殊处理, 即: 恢复 到收到 RRC连接重配置消息前的物理层参数配置。
第二种、 保持收到的最新物理层参数配置不变, UE试图通过底层发送 RRC连接重配置失败消息。 如果在超过最大重传次数后, RRC连接重配置 消息发送失败, UE释放相关无线资源, RRC直接迁态至空闲态 RRC_IDLE。 空闲态时 UE执行小区选择过程, 驻留到相应小区。
更进一步地, 如果釆用上述第一种方法恢复失败时, 则釆用上述第二 种方法所描述的过程进行处理。
综上所述, 釆用本发明, 简化了 RRC协议中重配置失败的处理, 避免 了任何一个参数配置异常时,都恢复到收到 RRC连接重配置消息前的配置。
进一步地, 在 RRC连接重配置失败消息中同时封装有设置的失败原因 值, 从而网络侧收到 RRC连接重配置失败消息后, 能根据增加的失败原因 值进行处理, 有利于网络侧根据实际情况进行后续的判决处理。 而现有技 术的 RRC连接重配置失败消息并未携带任何参数值。
进一步地, 本发明对恢复重配置前操作失败; 以及 RRC连接重配置失 败消息发送失败; 网络侧收到携带诊断原因的 RRC连接重配置失败消息的 后续处理, 均进行了规范; 可见, 本发明综合考虑到现有技术存在的各种 问题, 是对现有技术的完善, 解决了 RRC连接重配置由于部分配置失败, 导致该流程失败的后续处理。
以下对本发明进行举例阐述。
实例一:
釆用本发明,改进后的 RRC连接重配置过程中重配置失败的实现流程, 包括以下步骤:
步骤 401、 UE收到 RRC连接重配置消息, 顺序执行消息中各配置项。 各配置项包括以下内容, 以及针对各配置项的相对应的处理如下所示: 一、 如果 RRC连接重配置消息中包含无线资源配置部分, 则根据消息 内容重配置无线承载、 数据无线承载、 传输信道、 物理信道。 这里需要指 出的是: 这个配置过程即为针对物理层参数的配置。
二、 如果 RRC连接重配置消息中包含 UE相关信息部分, 则把新的小 区级无线网络临时标识赋值给 UE; 三、如果 RRC连接重配置消息中包含移动控制信息部分,则执行切换。 四、 如果 RRC连接重配置消息中包含非接入层专用信息部分, 则把此 字段部分传递给上层。
五、 如果 RRC连接重配置消息中包含测量相关信息部分, 则执行测量 配置部分修改。
步骤 402、 执行步骤 401中描述的五个配置项到某一项时, 执行失败, 重配置过程失败。
步骤 403、 维持当前配置, 无需恢复到收到 RRC连接重配置消息前的 配置。
步骤 404、根据执行到的配置项的具体配置执行情况,设置失败原因值。 步骤 405、 发送 RRC连接重配置失败消息, 携带设置的失败原因值。 步骤 406、 网络侧收到 RRC连接重配置失败消息, 根据顺序执行的约 定及失败原因值, 明确了 RRC连接重配置的执行情况及失败情况, 决定是 否重新建立 RRC连接, 修改承载、 测量参数, 还是直接释放 RRC连接等 的判决处理。
进一步的, RRC连接重配置由于物理层参数修改失败是一种特殊情况。 由于物理层没有恢复到收到重配置消息前的配置, 可能由于 UE/eNB 中一 些不同配置, UE试图通过底层发送 RRC连接重配置失败消息发送失败。 针对涉及到物理层参数的特殊情况, 给出下面两种具体实现方法。
实例二:
第一种具体实现方法:物理层参数配置失败导致 RRC连接重配置失败, 恢复到收到 RRC连接重配置消息前的物理层参数配置。 即仅修改上述流程 中的步骤 403为:
步骤 503、 物理层参数修改失败, 恢复到收到 RRC连接重配置消息前 的物理层配置。 这里, 物理层配置的恢复包括以下内容:
( a )恢复物理上行共享信道参考信令配置;
( b )恢复上行功率控制配置;
( c )恢复用于切换的物理上行公共控制信道配置;
( d )恢复物理上行共享信道配置;
( e )恢复专用信令信道质量指示报告配置;
( f )恢复 TDD物理信道配置;
( g )恢复传输天线配置。
如果上述步骤 503 中出现恢复物理层参数失败的异常情况, 按以下第 二种具体实现方法所描述的流程来处理。 当涉及物理层参数配置时, 如果 维持参数不变, 发送 RRC连接重配置失败消息, 发送消息失败后, 也釆用 以下第二种具体实现方法所描述的流程来处理。
实例三:
第二种具体实现方法的流程包括以下步骤:
步骤 601、 物理层参数恢复失败(即上述第一种具体实现方法中的异 常情况) 、 或者发送 RRC连接重配置失败消息发送失败。
步骤 602、 UE释放 RRC连接, 信令 /数据无线资源。
步骤 603、 UE返回空闲态。
步骤 604、 UE发起小区选择, 搜索到小区后, 驻留小区。 非接入层根 据需要, 决定是否发起位置更新等后续操作。
综上所述, 现有协议中, 对于 RRC连接重配置因部分配置失败, 导致 此流程失败的后续处理, 由于消息涉及参数较多, 协议描述的恢复配置操 作处理复杂, 同时, 对于一些异常情况及重配置操作失败原因, RRC协议 没有考虑。 而釆用本发明, 简化了 RRC连接重配置失败处理流程, 同时, 根据携带的失败原因,网络明确了 RRC连接重配置的执行情况及失败情况, 有利于网络侧根据实际情况进行后续处理。
一种 RRC连接重配置失败的处理***, 该***包括: 接收单元和执行 单元。 其中, 接收单元, 用于接收来自于网络侧的 RRC连接重配置消息。 执行单元, 用于执行 RRC连接重配置消息中的各参数对应的配置; 根据执 行到的当前参数的配置执行情况, 执行相对应的维持当前配置、 或恢复到 UE收到 RRC连接重配置消息前的配置。
针对执行单元而言, 执行单元, 进一步用于顺序执行 RRC连接重配置 消息中的各参数对应的配置。 当执行到的当前参数为非物理层参数时, 在 非物理层参数配置失败导致 RRC连接重配置失败的情况下, UE维持当前 非物理层参数的配置, 即: UE无需恢复到收到 RRC连接重配置消息前的 非物理层参数的配置。 当执行到的当前参数为物理层参数时, 在物理层参 数配置失败导致 RRC连接重配置失败时, UE恢复到收到 RRC连接重配置 消息前的物理层参数的配置; 或者, UE维持当前物理层参数的配置。
这里, 执行单元涉及不同配置参数的处理时, ***各单元的具体实现 有所不同, 以下分别阐述。
第一种具体实现: 在非物理层参数配置失败导致 RRC连接重配置失败 的情况下, 该***还包括: 设置及发送单元、 和判决处理单元。 其中, 设 置及发送单元, 用于维持配置的同时, 根据当前非物理层参数配置失败的 操作设置失败原因值; 将失败原因值封装到 RRC连接重配置失败消息中, 并发送给网络侧。
判决处理单元, 用于网络侧收到 RRC连接重配置失败消息后, 根据顺 序执行的约定和失败原因值执行判决处理。 其中, 判决处理包括: 判决是 否重新建立 RRC连接、 修改承载 /测量参数、 或者直接释放 RRC连接。
第二种具体实现: 在物理层参数配置失败导致 RRC连接重配置失败的 情况下, 该***还包括: 设置及发送单元、 和判决处理单元。 其中, 设置 及发送单元, 用于维持 /恢复物理层配置的同时, 根据当前物理层参数配置 失败的操作设置失败原因值; 将失败原因值封装到 RRC连接重配置失败消 息中, 并发送给网络侧。 判决处理单元, 用于网络侧收到 RRC连接重配置 失败消息后, 根据顺序执行的约定和失败原因值执行判决处理。
这里, 在 UE物理层参数的配置恢复失败、 或超过最大重传次数导致
RRC连接重配置失败消息发送失败的情况下, 该***还包括: 释放单元, 用于 UE释放 RRC连接的相关无线资源, 直接返回空闲态。 其中, 空闲态 时 UE执行小区选择过程, 驻留到相对应的小区。
这里需要指出的是: 以上涉及到的 RRC 连接重配置消息以 RRCConnectionReconfiguration 表示; RRC 连接重配置完成消息以 RRCConnectionReconfigurationComplete表示; RRC连接重配置失败消息以 RRCConnectionReconfigurationFailure表示; 连接态以 RRC—CONNECTED 表示; 无线资源配置部分以 radioResourceConfiguration表示; UE相关信息 部 分 以 UE-Relatedlnformation 表示 ; 移 动控 制 信 息 部 分 以 mobilityControlInformation 表示 ; 非 接入层 专 用 信 息 部 分 以 nas-Dedicatedlnformation 表 示 ; 测 量 相 关 信 息 部 分 以 measurementConfiguration表示; 空闲态以 Idle表示。
以上所述, 仅为本发明的较佳实施例而已, 并非用于限定本发明的保 护范围。
