本申请要求于 2008 年 4 月 14 日提交中国专利局、 申请号为 200810027428.X, 发明名称为"一种处理无线链路增加流程的方法、 设备及系 统"的中国专利申请的优先权, 其全部内容通过引用结合在本申请中。
技术领域
本发明涉及电子通信领域, 尤其涉一种处理无线链路增加流程的方法、一 种基站设备、 一种无线网络控制器以及一种通信系统。
背景技术
为了适应多媒体服务对高速数据传输日益增长的需要,第三代移动通信合 作项目组( 3GPP )提出了一种新的高速数据传输技术, 叫做高速下行分组接 入 ( High Speed Downlink Packet Access , HSDPA )。
宽带码分多址(Wideband Code Division Multiple Access, WCDMA ) 系统 引入 HSDPA后,在处理 IUB口( IUB口是无线网络控制器与基站之间的接口) 无线链路增加 (RADIO LINK ADDITION ) 流程, 尤其是在 RADIO LINK ADDITION伴随 HSDPA服务链路变更时,存在无线链路增加失败或是部分失 败, 但是 HSDPA服务链路变更成功的情况。 在这种情况下, 如果源服务链路 和目标服务链路在同一基站(NodeB ) 内, 且服务链路变更后可以进行数据转 移时, 基站侧的高速媒体接入控制 (MAC-hs ) 实体不需要复位。 然而, 发明 人在实现本发明的过程中发现, 在现有技术中, 当无线链路增加失败或部分失 败时,无线网络控制器仍然通知终端进行 MAC-hs实体复位,这将导致 NodeB 侧和 UE侧 MAC-hs实体复位不一致, 从而导致数据传输性能下降。

具体实施方式
下面结合附图,详细阐述本发明实施例的一种处理无线链路增加流程的方 法、 系统以及基站设备、 无线网络控制器的技术方案。
图 1 为本发明实施例的一种应用场景示意图。 WCDMA系统包括核心网 ( Core Network, CN ), 无线网络控制器( Radio Network Controller, RNC ), 基站(NodeB )。 RNC按照功能可以分为服务 RNC ( Serving RNC, SRNC )和 漂移 RNC ( Drift RNC, DRNC ), 其中, 服务 RNC是为当前终端提供到核心 网的连接的 RNC, 漂移 RNC是所述用户选定的新的目标小区所在的 RNC。 CN通过 IU口与 SRNC连接, SRNC通过 IUR口与 DRNC连接, SRNC通过 IUB 口与 NodeB连接, DRNC通过 IUB 口与 NodeB连接。 当终端从同一个 NodeB 下的一个小区软切换到另一个小区时, 无线网络控制器(包括 SRNC 和 /或 DRNC )通知 NodeB增加无线链路, 则 NodeB执行跨 IUB接口无线链 路增加流程。
在执行所述无线链路增加流程中, 可能伴随有服务链路变更, 如: 服务 HSDPA链路变更, 通过无线网络控制器发送给基站的无线链路增加请求 ( RADIO LINK ADDITION REQUEST )消息的 Serving E-DCH RL信元通知基 站进行服务链路变更。服务链路变更是指: 终端当前的服务链路从一小区的服 务链路变更到另一小区的服务链路,例如当终端检测到另外一个小区的信号比 较好时, 就有可能进行服务链路变更,从本小区的服务链路变更到信号比较好 的小区的服务链路上。 所述变更前的服务链路成为源服务链路, 变更后的服务 链路成为目标服务链路。
图 2所示为本发明实施例的一种处理无线链路增加流程的方法, 包括:
5201 , 基站接收无线网络控制器发送的无线链路增加请求(RADIO LINK ADDITION REQUEST ) 消息;
5202, 基站接收到所述 RADIO LINK ADDITION REQUEST消息后, 执 行无线链路增加处理, 并根据所述 RADIO LINK ADDITION REQUEST消息 中的 Serving E-DCH RL信元判断出需要进行服务链路变更, 则伴随进行服务 链路变更处理,将本基站的源服务链路变更到目标服务链路: 如果源服务链路 和目标服务链路涉及的小区为不同基站下的小区,则将终端的服务链路从另一 基站的源服务链路变更到本基站的目标服务链路;如果源服务链路和目标服务 链路涉及的小区为同一基站下的小区,则将终端的服务链路从本基站的源服务 链路变更到目标服务链路。
当基站增加无线链路部分或全部失败, 而伴随的 HDPSA服务链路变更成 功时,如果源服务链路和目标服务链路在同一基站内, 并且服务链路变更后可 以进行数据转移, 则所述基站不需要进行 MAC-hs实体的复位。 所述基站向所 述无线网络控制器返回一消息, 并在所述消息中添加用于指示终端不进行 MAC-hs实体复位的信息。
具体地, 所述消息可以为无线链路增加失败(RADIO LINK ADDITION FAILURE ) 消息, 在该 RADIO LINK ADDITION FAILURE消息中增加一个 MAC-hs RESET Indicator信元用于指示终端不进行 MAC-hs实体复位。 所述 MAC-hs RESET Indicator信元在 RADIO LINK ADDITION FAILURE消息的位 置, 请参考表 1的最后一行。
