Description

一种切换时无线资源的配置方法及装置 技术领域
本发明涉及通信中的切换技术, 尤其涉及一种切换时无线资源的配置 方法及装置。 背景技术
依据不同的标准, 切换可以分为很多种, 比如, 根据组网形式, 可以 分为同频切换与异频切换; 根据触发原因,可以分为基于负荷的切换、基于 覆盖的切换、 基于业务的切换和基于终端( UE )移动速度的切换;根据网 络拓朴结构,可以分为基站( eNB )内的切换、 同一移动性管理实体( MME ) 内不同 eNB间以及不同 MME不同 eNB间的切换。 但是, 对于 UE来说, 只依据是否有专用前导而分为竟争切换与非竟争切换, 而竟争切换与非竟 争切换在切换时的无线资源配置流程目前是一致的。
目前, 切换时的无线资源配置分为公用的和专用的两种, 专用的无线 资源配置又分为三类处理: 第一类是在切换成功后生效, 数据无线承载 ( DRB )配置、 测量间隙(GAP )配置、 信道质量指示(CQI )配置、 调度 请求(SR ) 配置和 Sounding参考符号 ( SRS ) 配置均属于第一类; 第二类 包括专用物理层配置 (physical Config Dedicated ), MAC配置 (mac-Main Config )和半静态调度(sps-Config )三项配置, 即时生效; 第三类是除一 类和二类之外的其它专用无线资源配置, 主要是信令无线承载( SRB )的修 改与 DRB的新增与修改, 即时生效。 公用的和上述第二类以及第三类专用 的无线资源配置即时生效, 而第一类专用无线资源配置在切换成功后生效。
图 1为现有技术对 UE切换成功时无线资源配置的处理的流程图, 图 2 为现有技术对 UE切换失败时无线资源配置的处理的流程图,可以看出, 目 前协议中对于切换成功时的无线资源处理流程为: 如果切换失败, 则对于 三类专用的无线资源配置, 需要回退到源小区的配置。
目前协议对切换时的无线资源配置, 按切换失败后是否需要回退, 可 以分为不需要回退的配置与需要回退的配置, 不需要回退的配置包括公用 无线资源配置、 一类和二类专用无线资源配置; 需要回退的配置是指三类 专用无线资源配置。
由此可以看出, 如果切换失败, 则对第三类专用无线资源配置的操作 显得多余, 切换前和切换后需要进行两次配置, 而其结果却是回到了切换 前的配置, 白白地浪费了系统资源, 加大了业务中断时间。 另外, 第三类 专用配置中主要是对 SRB (不包括 SRB0 ) 的修改与对 DRB的新增和修改 配置, 而在切换随机接入(RA )成功完成之前, 这些配置是不会被用到的。 但是一旦切换失败, 则切换前对第三类专用配置的操作完全没有了意义。 发明内容
本发明所要解决的技术问题是提供一种切换时无线资源的配置方法及 装置, 能够解决当前的切换中切换失败后的回退操作的问题, 缩短业务中 断时间, 节省系统开销, 提高系统资源利用率和系统的稳定性, 且具有很 强的可操作性和实用性。

所述 UE发起切换随机接入后,判定接入失败时,丟弃所述无线资源配 置参数中不可直接生效的无线资源配置参数。
进一步地, 上述方法还可包括: 所述 UE发起切换随机接入后, 所述 UE判定接入成功时, 配置所述无线资源配置参数中不可直接生效的无线资 源配置参数并生效, 并发送切换确认消息给所述基站。
进一步地, 所述可直接生效的无线资源配置参数包括以下一种或多种: 公用的无线资源配置以及专用无线资源配置中的信令无线承载 SRB、 专用 物理层 physical Config Dedicated配置、 MAC配置 mac-Main Config、 半静 态调度 sps-Config配置。
进一步地, 所述不可直接生效的无线资源配置参数包括以下一种或多 种: 数据无线承载 DRB配置、 测量间隙 GAP配置、 信道质量指示 CQI配 置、 调度请求 SR配置和探测 Sounding参考符号 SRS配置。
进一步地,所述 UE丟弃不可直接生效的无线资源配置参数后,还包括: 所述 UE发起切换失败触发的无线资源控制协议 RRC重建立流程以恢 复连接。
本发明还提供了一种切换时无线资源的配置装置, 包括: 接收单元和 控制单元, 其中,
所述接收单元, 用于接收基站下发的携带无线资源配置参数的切换命 令, 并传送给所述控制单元;
所述控制单元, 用于对接收的所述无线资源配置参数中可直接生效的 无线资源配置参数进行配置且生效; 并在发起切换随机接入后, 判定接入 失败时, 丟弃所述无线资源配置参数中不可直接生效的无线资源配置参数。
进一步地, 所述控制单元, 还用于在发起切换随机接入后, 判定接入 成功时, 配置所述无线资源配置参数中不可直接生效的无线资源配置参数 并生效, 发送切换确认消息给所述基站。
进一步地, 所述控制单元配置的所述可直接生效的无线资源配置参数 包括以下一种或多种: 公用的无线资源配置以及专用无线资源配置中的信 令无线承载 SRB、 专用物理层 physical Config Dedicated 配置、 mac-MainConfig, 半静态调度 sps-Config配置。
进一步地, 所述控制单元配置的所述不可直接生效的无线资源配置参 数包括以下一种或多种: 数据无线承载 DRB配置、 测量间隙 GAP配置、 信道质量指示 CQI配置、调度请求 SR配置、 Sounding参考符号 SRS配置。
进一步地, 所述控制单元, 还用于在丟弃不可直接生效的无线资源配 置参数后, 发起切换失败触发的无线资源控制协议 RRC重建立流程以恢复 连接。
与现有技术相比, 应用本发明, 解决了当前的切换中若切换失败后的 回退操作的问题, 缩短了业务中断时间, 节省了系统开销, 提高了系统资 源利用率和系统的稳定性 , 具有很强的可操作性和实用性。 附图说明
图 1为现有技术对 UE切换成功时无线资源配置的处理的流程图; 图 2为现有技术对 UE切换失败时无线资源配置的处理的流程图; 图 3为本发明对 UE在切换成功时无线资源配置的处理的流程图; 图 4为本发明对 UE在切换失败时无线资源配置的处理的流程图; 图 5为本发明切换时无线资源的配置装置的结构示意图。 具体实施方式
下面结合附图和具体实施方式对本发明作进一步说明。
本发明的主要构思是: 将切换命令中携带的无线资源配置参数分为两 类: 一类是可直接生效的无线资源配置参数, 包括: 公用的无线资源配置 以及专用无线资源配置中的 SRB、 physical Config Dedicated 配置、 mac-Main Config配置和 sps-Config配置中的一种或多种; 另一类是不可直 接生效的无线资源配置参数, 包括: 数据无线承载 DRB 配置、 测量间隙 GAP配置、 信道质量指示 CQI配置、 调度请求 SR配置和探测(Sounding ) 参考符号 SRS配置中的一种或多种。 可直接生效的无线资源配置在收到切 换命令后直接生效, 不可直接生效的无线资源配置在切换成功后生效, 在 切换失败后自动丟弃, 这样就避免了切换失败后的回退操作, 缩短了业务 中断时间, 节省了系统开销。
本发明将 SRB也归类到可直接生效的无线资源配置中,是因为切换 RA 成功之后, 要在 SRB1上发送 RRC Connection Reconfiguration Complete消 息; 而如果切换失败, 会自动触发 RRC重建立流程, 那时会对 SRB1重新 进行配置, 所以将 SRB归类到可直接生效的无线资源配置中没有影响。 资源配置的处理, 分为切换成功的用例与切换失败的用例。
UE在切换时进行的与无线资源配置无关的其它操作,如同步到目标小 区等, 不在本发明的描述范围之内。
图 3为本发明对 UE在切换成功时无线资源配置的处理的流程图,如图
3所示, 该流程包括:
步驟 301 :基站向终端 UE下发切换命令,其中携带无线资源配置参数。 步驟 302、 UE收到切换命令后, 将无线资源配置参数中可直接生效的 无线资源配置参数直接配置到相应模块, 并立即生效。
可直接生效的无线资源配置参数包括以下一种或多种: 公用的无线资 源配置以及专用无线资源配置中的 SRB、 physical Config Dedicated , mac-Main Config和 sps-Config配置等。
步驟 303: UE发起切换随机接入, 判断若接入成功。
步驟 304: UE发送切换确认消息给基站, 确认切换成功。
步驟 305: UE即时配置生效所述无线资源配置参数中不可直接生效的 无线资源配置参数, 包括 DRB、 GAP, CQI、 SR和 SRS配置等。
图 4为本发明对 UE在切换失败时无线资源配置的处理的流程图,如图 4所示, 切换失败的实例包括如下步驟:
步驟 401 :基站向终端 UE下发切换命令,其中携带无线资源配置参数。 步驟 402: UE收到切换命令后, 将无线资源配置参数中可直接生效的 无线资源配置参数直接配置到相应模块, 并立即生效。
可直接生效的无线资源配置参数包括: 公用的无线资源配置以及专用 无线资源配置中的 SRB、 physical Config Dedicated, mac-Main Config和 sps-Config配置等。
步驟 403: UE发起切换随机接入, 判断若接入失败。
步驟 404: UE直接丟弃所述无线资源配置参数中不可直接生效的无线 资源配置参数, 包括 DRB、 GAP, CQI、 SR和 SRS配置等。
步驟 405: UE发起切换失败触发的 RRC重建立流程以恢复连接, RRC 重建立流程会触发对无线资源的重新配置。
将现有技术与本发明的实施方案进行对比, 可充分突出本发明方案的 优越性。 在现有技术中, UE切换失败时, 要将三类无线资源配置参数(包 括对 SRB的修改与 DRB的新增与修改) 回退到切换前源小区下发的配置 状态, 然后才能发起切换失败触发的 RRC重建立流程以恢复连接。 而这些 需要回退的配置,在 UE进行配置生效以后还没有被用到过,说明一旦切换 失败, 对这些参数的配置是多余的, 不但增加了切换时的业务中断时间, 还浪费了系统资源。
如图 4所示, 本发明实施方案中, 进行以下改进: 把切换时的所有无 线资源配置分为在切换失败后不需要回退的配置和需要回退的配置。 不需 要回退的配置在切换前统一实时生效, 而需要回退的配置在切换成功后再 统一配置生效。 这样, 当切换失败后, 就省去了两倍于进行参数回退操作 的时空资源, 提高了系统资源利用率。
本发明所述的一种切换时的无线资源处理方法, 并不仅仅限于说明书 及实施方案中所列运用, 完全可以被适用于各种适合本发明之领域。
图 5为本发明切换时无线资源的配置装置的结构示意图, 如图 5所示, 本发明的切换时无线资源的配置装置包括: 接收单元和控制单元, 其中; 所述接收单元, 用于接收基站下发的携带无线资源配置参数的切换命 令, 并传送给所述控制单元;
所述控制单元, 用于对接收的所述无线资源配置参数中可直接生效的 无线资源配置参数进行配置且生效; 发起切换随机接入后, 判断若接入失 败, 则丟弃所述无线资源配置参数中不可直接生效的无线资源配置参数。
所述控制单元还用于, 发起切换随机接入后, 判断若接入成功, 则发 送切换确认消息给所述基站, 配置所述无线资源配置参数中不可直接生效 的无线资源配置参数并生效。
所述控制单元配置的所述可直接生效的无线资源配置参数包括: 公用 的无线资源配置以及专用无线资源配置中的 SRB、 physical Config Dedicated 配置、 mac-Main Config和 sps-Config配置中的一种或多种。
所述控制单元配置的所述不可直接生效的无线资源配置参数包括: 数 据无线承载 DRB配置、 测量间隙 GAP配置、 信道质量指示 CQI配置、 SR 配置和 SRS配置中的一种或多种。
所述控制单元还用于, 丟弃不可直接生效的无线资源配置参数后, 发 起切换失败触发的无线资源控制协议 RRC重建立流程以恢复连接。
以上所述, 仅为本发明较佳的具体实施方式, 但本发明的保护范围并 不局限于此, 任何熟悉该技术的人在本发明所揭露的技术范围内, 可轻易 想到的变化或替换, 都应涵盖在本发明的保护范围之内。 因此, 本发明的 保护范围应该以权利要求的保护范围为准。
