一种高速媒体接入控制实体的重置方法,包括:接收无线网络控制器发送的重置指令,所述重置指令包括:小区的重置指示信息;根据所述重置指示信息确定重置小区,并对所述重置小区执行高速媒体接入控制实体的重置。

Description

高速媒体接入控制实体的重置方法及相关装置 技术领域
本发明涉及无线通信领域,尤其涉及一种高速媒体接入控制实体的重置方 法及相关装置。
背景技术
通用移动通讯系统 ( UMTS, Universal Mobile Telecommunications System ) 在版本 5 ( Rel-5 ) 中引入了高速数据包接入 ( HSDPA, High Speed Data Packet Access )特性, 以进一步提升 UE的峰值吞吐和小区吞吐。 当 UE配置了 HSDPA 后, 会配置一个且仅有一个高速共享控制信道(HS-DSCH, High Speed
Downlink Shared Channel )服务小区, UE的所有 HSDPA物理信道都仅建立在 这个 HS-DSCH服务小区上, 此时 UE侧有一个高速媒体控制实体(MAC-hs, High speed Medium Access Control )或增强高速媒体控制实体 ( MAC-ehs, Enhanced High speed Medium Access Control ) 实体用于处理 MAC层的数据接 收, 对应地, 在网络侧, HS-DSCH服务小区也配置有一个 MAC-hs或 MAC-ehs 实体用于处理 HS-DSCH数据在 MAC层的发送。
UMTS技术演进到 Rel-11时, 引入了多流传输( Multiflow )特性, 该特性 允许同频或异频上多个小区可以配置为 UE发送 HS-DSCH数据, 小区边缘用户 的体验可以得到明显提升。 用户可以同时配置最多 4个 Multiflow小区, 分别是 Cell-1, Cell-2, Cell-3, Cell-4, 其中 Cell-1和 Cell-2在频率 1上, Cell-3和 Cell-4在频 率 2上。 在 Multiflow小区中有一个小区称为 UE的 HS-DSCH服务小区或主小区, 和 HS-DSCH服务小区同频的另外一个小区称为 UE的 HS辅助服务小区或辅助 小区或协助小区, 和 HS-DSCH服务小区有相同的定时关系的另外一个小区称 为 UE的 HS辅服务小区或辅小区, 和 HS辅服务小区同频的另外一个小区称为 UE的 HS辅助辅服务小区或辅助辅小区或协助辅小区。
HS-DSCH服务小区切换过程中的 MAC-hs/MAC-ehs的处理:
在协议中, MAC-hs和 MAC-ehs都用于处理在 HS-DSCH上传输的数据, MAC-hs和 MAC-ehs的配置信息是由 RRC层控制的。 在网络侧每个小区有一个 MAC-hs/MAC-ehs实体, MAC-hs或 MAC-ehs主要的功能包括: 流控、 调度 /优 先级处理、 HARQ功能、 TFRC选择; MAC-ehs实体是对 MAC-hs实体的增强, 其增加的功能主要是可以对 MAC-ehs SDU的分割。 UE侧在 Rel-5弓 1入 HSDPA 时, 规范了 UE侧仅有一个 MAC-ehs实体, 对应 HS-DSCH服务小区。
在现有技术中, 当 UE移动时, 可能会触发 UE的 HS-DSCH服务小区切换, 并且可能伴 MAC-hs/MAC-ehs重置; Multiflow中, 多个 Multiflow小区可以在同 一个 Node B或不同 Node B , 当在不同 Node B时, 要求 UE侧有两个 MAC-ehs来 分别处理每个 Node B发送的下行数据。以 Multiflow中的单频点双小区( SF-DC, Single Frequency Dual Cell )模式为例, 由于 UE的 SF-DC主小区和辅助小区对 应的 MAC-ehs可能发生变化, 按照现有协议的流程, 此时网络侧会发起
MAC-ehs重置过程, RNC仅会指示 UE将主小区对应的 MAC-ehs内的緩存数据 清空且将该 MAC-ehs设置为初始状态, 而对于辅助小区对应的 MAC-ehs的处理 则没有规范或指示 UE要将两个 MAC-ehs内的緩存数据都清空, 并同时将两个 MAC-ehs都设置为初始状态。
现有技术中的 MAC-hs/MAC-ehs重置做法会带来两个问题: 一是导致 UE 在切换后不知道辅助小区对应的 MAC-ehs应该怎么处理, 因而会导致 UE行为 异常; 二是切换后 UE必须要将两个 MAC-ehs内的緩存数据都清空并且设置为 初始状态, 因为 MAC-hs/MAC-ehs重置时, 緩存的 MAC层数据都会丟失, 此时 必须要触发更高层次(比如无线链路控制层的重传), 这样系统的性能会受到 影响(具体表现在对数据业务的中断, 或者下行的空口信令丟失从而导致掉话 等) 。 现有技术中的 MAC-hs/MAC-ehs重置做法会影响用户体验, 比如视频播 放不畅, 打电话突然掉话等。 发明内容

具体实施方式
本发明实施例提供了一种高速媒体接入控制实体的重置方法及相关装置, 用于避免用户设备异常的行为和避免进行不必要的高速媒体接入控制实体的 重置。
在实际应用中, 当用户设备移动时, 触发用户设备进行小区切换, 在小区 切换之后, 可能会导致高速媒体接入控制实体和小区的映射信息发生改变, 因 此, 需要进行高速媒体接入控制实体重置。
请参阅图 1 , 为本发明实施例中高速媒体接入控制实体的重置方法的流程 示意图。
101、 用户设备接收无线网络控制器发送的重置指令。
用户设备接收无线网络控制器发送的重置指令, 所述重置指令包括: 小区 的重置指示信息,所述小区的重置指示信息用于指示需要进行高速媒体接入控 制实体重置的小区 (简称重置小区)。
在发生小区切换(具体可以为 HS-DSCH服务小区的切换)时, 网络侧设 备(如, 基站或无线网络控制器)会根据小区切换前后的小区信息确定需要进 行高速媒体接入控制实体重置的小区,网络侧设备可以通过小区的重置指示信 息在所述重置指令指示重置小区。
进一步地, 所述小区的重置指示信息也可以仅指示辅助小区和 /或辅助辅 小区需要进行高速媒体接入控制实体重置,也即重置指示信息指示的重置小区 仅包含辅助 d、区和 /或辅助辅小区。
进一步地, 如果用户设备没有接收到无线网络控制器发送的重置指令, 则 用户设备按照现有技术中规范的行为去判定需要进行高速媒体接入控制实体 重置的小区。
102、 用户设备根据所述重置指示信息确定重置小区, 仅对所述重置小区 执行高速媒体接入控制实体的重置。
由于所述重置指示信息中标记有重置小区, 因此, 用户设备可以根据所述 重置指示信息确定重置小区。
在用户设备进行小区切换时, 接收所述无线网络控制器发送的重置指令, 用户设备根据所述重置指示信息确定重置小区,并对所述重置小区执行高速媒 体接入控制实体的重置,从而避免了用户设备异常的行为和避免进行不必要的 高速媒体接入控制实体的重置, 改进了用户体验。
在实际应用中,用户设备可能不具备重置至少一个进行高速媒体接入控制 实体重置的能力, 该能力同时包括 (1)用户设备在切换后同时重置两个或多于 两个高速媒体接入控制实体 (2)重置其中一个高速媒体接入控制实体, 而不重 置另外至少一个高速媒体接入控制实体。 因此, 不具备这种能力的用户设备收 到重置指令就会直接忽略或者导致异常的用户设备行为(和网络侧的行为不一 致的行为), 浪费网络侧的信令开销, 本发明提供了相应的解决方案, 具体请 参阅图 2, 为本发明另一实施例中高速媒体接入控制实体的重置方法的流程示 意图。

进一步地,所述小区的重置指示信息可以仅在非主小区的小区配置信息中 携带, 比如辅助小区, 或辅小区, 或辅助辅小区的配置信息, 在这些小区配置 信息中携带时, 重置指示信息的指示内容同上描述。
203、 用户设备根据所述重置指示信息确定重置小区, 并仅对所述重置小 区执行高速媒体接入控制实体的重置。
