一种用户面配置参数的处理方法及装置 技术领域
本发明涉及无线接入系统的服务质量(QoS, Quality of Service )技术, 尤其涉及一种用户面配置参数的处理方法及装置。 背景技术
在无线通信系统中, 无线接入技术是指利用微波、 卫星、 红外线等传 输方式将用户终端接入到业务节点, 为用户提供各种业务的通信技术。 无 线接入技术分为固定无线接入技术和移动无线接入技术。 其中, 移动无线 接入技术就是我们所熟悉的蜂窝移动电话系统和卫星通信系统所采用的技 术, 移动无线接入技术服务的对象是移动终端, 用于实现移动终端与固定 终端或移动终端之间的信息交换。
而对于固定位置的用户或仅在小范围内移动的用户群体, 则可采用固 定无线接入技术。 在通信网中, 无线接入系统是本地通信网的一部分、 是 本地有线通信网的延伸、 补充和临时应急系统。 无线接入系统一般由无线 接入设备和终端组成, 终端可以通过无线接入设备与骨干网或其他无线接 入网相连接。 如图 1 所示, 终端和无线接入设备通过无线接口连接, 各无 线接入设备之间可以通过无线接口或有线接口连接, 无线接入设备和骨干 网之间通过有线接口连接。
随着移动互联网 (Mobile Internet )和智能手机的普及, 移动数据流量 需求飞速增长。 室内和热点地区数据业务体现为低速移动、 带宽需求大、 流量需求高、业务以纯 IP数据互联网业务为主、以及 QoS要求单一等特点。 多媒体互联网业务日益丰富, 数据业务带宽需求较大, 各种大带宽的数据 卡和智能终端, 对总得流量需求也在增加, 为了满足需求, 移动无线接入 技术需要具备大带宽和大流量的特点。
QoS是网络的一种安全机制, 是用来解决网络延迟和阻塞等问题的一 种技术。 对于网络业务, QoS 包括传输的带宽、 传送的时延、 数据的丟包 率等。 在网络中可以通过保证传输的带宽、 降低传送的时延、 降低数据的 丟包率和时延抖动等措施来提高 QoS。
网络资源是有限的, 只要存在抢夺网络资源的情况, 就会出现 QoS的 要求。 QoS是相对网络业务而言的, 在保证一类业务的 QoS时, 可能就是 在损害其它业务的 QoS。 例如, 在网络总带宽固定的情况下, 如果一类业 务占用的带宽越多, 那么其他业务能使用的带宽就越少, 可能会影响其他 业务的使用。 因此, 网络管理者需要根据各种业务的特点, 对网络资源进 行合理的规划和分配, 才能使网络资源得到高效利用。
在演进分组系统( EPS, Evolved Packet Core system ) 中, QoS控制的 基本粒度是承载( Bearer ),即相同承载上的所有数据流量将获得相同的 QoS 保障, 不同类型的承载提供不同的 QoS保障。 承载级 QoS参数包括业务类 别标识(QCI, QoS Class Identifier ), 分配与保持优先级( ARP, Allocation and Retention Priority ), 保证速率(GBR, Guaranteed Bit Rate )、 最大比特 速率(MBR, Maximum Bit Rate )和聚合最大比特速率(AMBR, Aggregate Maximum Bit Rate )。 在无线接入网络 ( RAN, Radio Access Network )侧, 一个无线承载(RB, radio bearer )对应一个 EPS承载。 如图 2所示, 在用 户侧,每个 RB对应一个分组数据汇聚协议( PDCP, Packet Data Convergence Protocol ) 实体和一个无线链路控制层(RLC, Radio Link Control ) 实体, 并且由媒体接入控制 (MAC, Medium Access Control )层进行调度, 来保 证无线侧用户承载的 QoS。 其中, PDCP提供的具体服务包括: 进行头压缩 和解压缩, 如用户平面数据和控制平面数据的加密 /解密; 提供 PDCP序 列号, 供无线承载使用等。 RLC层支持的功能包括: 传送 RLC协议数据单 元(PDU, Protocol Data Unit ), 以及分段、 组合和重组 RLC SDU。 MAC 层提供的主要功能包括: 逻辑信道与传输信道之间的映射, 转发混合自动 重传请求(HARQ, Hybrid Automatic Repeat Request ), 在 UE的逻辑信道 之间进行优先级处理,在各 UE之间借助动态调度进行优先级处理,传输格 式选择, 逻辑信道优先级管理等。
对于 QoS机制与 RAN的 QoS机制类似的无线接入设备而言, 每一个 RB都有一套 PDCP的配置参数、 RLC的配置参数和 MAC层的配置参数, 用于建立用户面实体。 实际应用中, 上述用于建立用户面实体的用户面配 置参数需要由无线接入设备的网管配置、 或控制面实体分配, 并需要由无 线接入设备的控制面实体发送到终端的用户面实体和无线接入设备的用户 面实体。 这样, 不仅会增加无线接入设备实现的复杂度, 而且会增加无线 接入设备与终端之间交互的信令开销, 从而增加了无线接入设备和终端的 实现成本, 因此, 需要简化无线接入系统中的 QoS机制。 发明内容

步驟 306: 业务 1进行 QoS参数修改后, 无线接入设备 1判断是否需 要修改用户面配置参数, 如果是, 则继续步驟 307, 否则, 结束当前流程; 具体地, 无线接入设备 1 通过网管或无线资源管理算法获取更新后的 索引信息, 将更新后的索引信息与当前所采用用户面配置参数的索引信息 相比较, 如果相同, 则不需要修改用户面配置参数, 如果不相同, 则需要 修改用户面配置参数。
步驟 307:无线接入设备 1向终端 1发送更新后的用户面配置参数索引 信息, 无线接入设备 1 的控制面处理单元发送更新后的用户面配置参数索 引信息到自身的用户面处理单元;
