Description

一种实现业务释放的方法、 系统及演进节点 B
技术领域
本发明涉及长期演进(Long Term Evolution, LTE )无线通讯领域, 尤其 涉及一种实现业务释放的方法、 系统及演进节点 B ( Evolution NodeB, eNB )。
背景技术
LTE系统中, 用户设备(User Equipment, UE ) 、 eNB和移动管理实体 ( Mobility Management Entity, MME )的连接关系如图 1所示。 其中, UE和 eNB之间的接口是 Uu接口, eNB和 MME之间的接口是 S1接口。 UE和 eNB、 以及 eNB和 MME之间发送的消息都需要经过抽象语法标记( Abstract Syntax Notation One, ASN.l )编码, 收到的消息也都需要经过 ASN.l解码。
业务在 MME和 eNB之间使用演进通用陆地无线接入网络无线承载标识 ( E-UTRAN RADIO BEARER IDENTITY, E-Rabld )标识, 在 UE和 eNB之 间使用数据无线承载标识(DATA RADIO BEARER IDENTITY, Drbld )标识, 且 E-Rabld和 Drbld——对应。 UE和 eNB之间的信令使用信令无线承载标识 ( SIGNALLING RADIO BEARER IDENTITY, Srbld )标识。
业务删除是指 UE在结束某种业务, 比如结束了视频通话、 语音通话或 某个下载等操作, 但是并没有结束所有业务时, 触发 MME来释放该业务所 占用的各种资源的过程。
UE和 MME之间的业务删除(也称业务释放 )可以由 UE的非接入 ( Non Access Stratum, NAS )层发起, 也可以由 MME的 NAS层发起, 表现在接入 层就是 MME发起业务承载释放请求。 也就是说业务的释放分两个层次: 一 个是 NAS层的释放, 一个是接入层的释放。
通常, 业务释放过程包括: UE发起 NAS层的资源修改请求(指示标志 为删除承载, 且其中携带待删除业务的标识) ; MME收到后, 向 eNB发送 NAS层的去激活请求(该消息包含在业务释放请求消息里) ; eNB收到后, 向 UE发送无线资源控制 ( Radio Resource Control, RRC )连接重配置消息; UE释放完成后, 向 eNB发送 RRC连接重配置完成消息, 由 eNB向 MME发 送去激活接受消息。
在上述过程中, UE在收到 RRC连接重配置消息后, 由于无线链路失败 等原因可能会导致 UE的 RRC连接重配置过程失败。此时 UE会发起 RRC连 接重建立过程。 如图 2所示, 包括以下步骤:
201、 UE向 eNB发起 RRC连接重建立请求;
202、 eNB收到后, 重建或重配置本地的 UE资源, 并向 UE回复 RRC 连接重建立消息, 目的是建立 RRC连接;
203、 UE重新建立好本地实体后, 向 eNB回复 RRC连接重建立完成消 息;
204、 RRC连接重新建立完成后, eNB发起一个 RRC连接重配置过程。 eNB向 UE发送 RRC连接重配置消息, 该消息中不携带业务相关信息, 以通 知 UE恢复 RRC连接重建立前 UE所有存在的业务;
205、 UE恢复业务完毕后, 向 eNB发送 RRC连接重配置完成消息; 206、 eNB向 MME发送业务释放失败响应, 本次业务释放失败。
上述过程中存在一个比较严重的问题, 即当用户要求释放一个业务时, 由于 UE接入层重配置失败,导致 RRC连接需要重新建立, 随后在 eNB发起 的 RRC连接重配置过程, 会使 UE恢复其本要释放的业务, 最终导致业务释 放失败。 而且, 重复的 RRC连接重配置失败和 RRC连接重建立过程也会使 Uu口的 RRC连接重建立和 RRC连接重配置过程陷于循环过程。这违背了用 户的意愿, 同时, MME也无法处理这种情况, 只能释放 UE上下文, 导致用 户的所有业务中断。

本发明的较佳实施方式
下面将结合附图及实施例对本发明的技术方案进行更详细的说明。
本发明所述方法的基本构思是: 在 NAS层业务释放过程中, 由于 UE接 入层重配置失败而导致的该 UE与 eNB之间的 RRC连接重建立完成后, eNB 在向该 UE发送 RRC连接重配置消息中携带建立或修改业务列表, 该列表中 包含该 UE上除了待释放业务之外的所有业务的标识; UE收到后, 恢复该建 立或修改业务列表中包含的标识所对应的业务。
UE按照 RRC 重配置消息中的建立或修改业务列表进行业务建立成功 后, 等同于把待释放的业务释放掉了。
具体地, 在 LTE系统中, 业务释放的方法可包括如下步骤:
第一步, UE发起 NAS层的资源修改请求, 其中携带待释放业务的标识; 第二步, MME收到后, 向 eNB发送业务释放请求消息, 其中携带待释 放业务的 E-Rabld;
第三步, eNB收到后, 向 UE发送 RRC连接重配置消息, 该消息中携带 待释放业务的 Drbld;
第四步, UE处理 RRC连接重配置失败, 向 eNB发送 RRC连接重建立 请求消息;
第五步, eNB收到 RRC连接重建立请求消息后, 重建立或重配置本地的 UE资源, 然后向 UE回复 RRC连接重建立消息, 目的是建立 RRC连接; 第六步, UE重建立好本地实体后, 向 eNB发送 RRC连接重建立完成消 息; 第七步, eNB收到后, 向 UE发送 RRC连接重配置消息, 该消息中要携 带建立或修改业务列表,该列表中不包含第一步中待释放业务的 Drbld。可选 的操作是携带删除业务列表, 列表中携带 UE上全部业务的 Drbld;
第八步, UE按照建立或修改业务列表中包含的 Drbld恢复对应的业务。 此时, 如果 RRC连接重配置消息中还携带删除业务列表, 则先执行释放所有 业务的操作, 然后再恢复建立或修改业务列表中包含的 Drbld对应的业务。
在本步骤中, 如果 RRC连接重配置成功(即将建立或修改业务列表中包 含的 Drbld对应的业务都恢复成功) , UE会向 eNB发送 RRC连接重配置完 成消息, eNB收到后, 会向 MME发送业务释放成功响应, 其中携带上述待 释放业务的 E-Rabld。
如果 RRC连接重配置再次失败, UE会再次向 eNB发送 RRC连接重建 立请求消息; eNB收到后,向 UE回复 RRC连接重建立拒绝消息,并向 MME 回复业务释放失败响应, 其中携带上述待释放业务的 E-Rabld。 此外, eNB 还可以向 MME发起 UE上下文释放请求 , 请求释放 UE资源。
相应的实现业务释放的系统包括: 要释放业务的 UE及 eNB;
在 NAS层业务释放过程中, 由于 UE接入层重配置失败而导致的 UE与 eNB之间的 RRC连接重建立完成后, 该 eNB用于向 UE发送 RRC连接重配 置消息, 其中携带建立或修改业务列表, 该列表中包含 UE上除了待释放业 务之外的所有业务的标识;
UE用于在收到 RRC连接重配置消息后, 恢复所述建立或修改业务列表 中包含的标识所对应的业务。
所述 RRC连接重配置消息中还携带删除业务列表,所述删除业务列表中 包含所述 UE上所有业务的标识;
所述 UE用于在收到所述 RRC连接重配置消息后, 先释放所述删除业务 列表中包含的标识所对应的业务, 然后再恢复所述建立或修改业务列表中包 含的标识所对应的业务。
该系统中还包括 MME; UE还可用于在完成业务恢复后, 向 eNB发送 RRC连接重配置完成消息; eNB还可用于在收到 RRC连接重配置完成消息 后, 向 MME发送业务释放成功响应, 其中携带待释放业务的标识; MME用 于接收该业务释放成功响应。
UE还可用于在再次 RRC重配置失败后, 再次向 eNB发送 RRC连接重 建立请求; eNB还可用于在再次接收到 RRC连接重建立请求后, 向 UE回复 RRC连接重建立拒绝消息, 并向 MME回复业务释放失败响应。
eNB还可用于在再次接收到 RRC连接重建立请求后, 向 MME发送 UE 上下文释放请求; MME用于在收到 UE上下文释放请求后, 释放 UE资源。
另一种实现业务释放的方法, 包括: 在 NAS层业务释放过程中, 由于 UE接入层重配置失败而导致的 UE与 eNB之间的 RRC连接重建立完成后, 该 eNB在向 UE发送 RRC连接重配置消息中携带删除业务列表,该列表中包 含待释放业务的标识; 该 UE收到后, 恢复该 UE上除上述待释放业务之外的 所有业务。 其他各相关步骤可同上述具体说明, 在此不再进行赞述。
相应地实现业务释放的系统包括要释放业务的 UE和 eNB;
在 NAS层业务释放过程中, 由于 UE接入层重配置失败而导致的 UE与 eNB之间的 RRC连接重建立完成后, eNB用于向 UE发送 RRC连接重配置 消息, 其中携带删除业务列表, 该列表中包含待释放业务的标识;
UE用于在收到 RRC连接重配置消息后, 恢复该 UE上除上述待释放业 务之外的所有业务。

RRC连接重配置完成消息; eNB还用于在收到 RRC连接重配置完成消息后, 向 MME发送业务释放成功响应, 其中携带待释放业务的标识; MME用于 接收该业务释放成功响应。
UE还可用于在再次 RRC重配置失败后, 再次向 eNB发送 RRC连接重 建立请求; eNB还可用于在再次接收到 RRC连接重建立请求后, 向 UE回复 RRC连接重建立拒绝消息 , 并向 MME回复业务释放失败响应。
eNB还可用于在再次接收到 RRC连接重建立请求后, 向 MME发送 UE 上下文释放请求; MME用于在收到 UE上下文释放请求后, 释述 UE资源。 实施例 1 :
