LTE 系统可以采用统一的服务质量类别标识 (Quality of service Class Identifier,以下简称: QCI ) 定义服务质量, 将几种典型的服务质量类别用标 准化的方法定义为一系列的值来匹配, 即使用标准 QCI。 但考虑到业务需求 的多样化, 标准 QCI并不能完全满足各种灵活的业务需求, 在标准中仍然允 许运营商自己定义九种标准化的 QCI级别之外的 QCI, 即由运营商自定义的 扩展服务质量类别标识 QCI。
在实现本发明过程中, 发明人发现现有技术中至少存在如下问题: 由于 各运营商使用了各自定义的扩展 QCI, 当发生跨 PLMN的切换时, 无法保证 服务质量的连续性。

为使本发明实施例的目的、 技术方案和优点更加清楚, 下面将结合本发 明实施例中的附图, 对本发明实施例中的技术方案进行清楚、 完整地描述, 显然, 所描述的实施例是本发明一部分实施例, 而不是全部的实施例。 基于 本发明中的实施例, 本领域普通技术人员在没有作出创造性劳动前提下所获 得的所有其他实施例, 都属于本发明保护的范围。
针对现有技术中允许各运营商使用自己定义的 QCI, 即扩展 QCI, 而在 小区切换时, 尤其是在跨 PLMN的小区切换时, 且切换前后的服务小区属于 不同的基站时, 会存在目标小区服务基站不为源小区的运营商提供服务, 因 此不存储其自定义的扩展 QCI, 导致切换后目标小区无法获取确定源小区使 用的扩展 QCI的服务质量参数的缺陷, 本发明实施例提供了一种服务质量信 息处理方法, 图 1为本发明服务质量信息处理方法实施例的流程示意图, 如 图 1所示, 该方法包括以下内容。
101, 基站间交互扩展服务质量类别标识相关信息。
102,根据所述扩展服务质量类别标识相关信息识别切换用户使用的扩展 服务质量类别标识, 并建立空口承载。
本实施例提供的服务质量信息处理方法, 通过在基站间交互扩展服务质 量类别标识相关信息, 能够实现在跨 PLMN的服务小区切换时, 目标小区也 能够识别由源小区自定义的扩展 QCI, 保证服务质量连续性。
本实施例中, 在基站间交互的信息可以不仅包括上述的扩展服务质量类 别标识相关信息,还可包括上述扩展服务质量类别标识归属的 PLMN的标识。 具体的,针对使用公共接口信令交互的情况,可以交互上述的 PLMN的标识, 而使用专用接口时则可以不交互 PLMN的标识。 在 101 中, 基站间进行交互扩展服务质量类别标识相关信息时, 可以是 基站间通过 X2口消息和 /或 S1口消息交互所述扩展服务质量类别标识相关信 息。通过上述的 X2口消息和 /或 S 1 口消息交互扩展 务质量类别标识相关信 息, 可以不增加现有流程。 上述 101可以具体包括如下实现方法:
( 1 )进行小区切换的过程中进行小区切换和 QCI相关信息的交互, 即 在小区切换时,基站间通过 X2口消息和 Z或 S1 口消息交互所述 展服务质量 类别标识相关信息。
上述基站间通过 X2 口消息交互所述扩展服务质量类别标识相关信息可 以具体为: 通过 X2 口切换消息交互本基站服务小区所支持的扩展服务质量 类别标识及其对应的解析信息。上述基站间通过 S1 口消息交互所述扩展服务 盾量类别标识相关信息可以具体为:通过 S1 口消息经由核心网节点交互本基 站服务小区所支持的扩展服务质量类别标识及其对应的解析信息。
上述切换过程中, 源小区服务基站和目标小区服务基站可以存储接收到 的扩展服务质量类别标识及其对应的解析信息, 以供下次切换时查询使用; 也可以不存储接收到的扩展服务质量类别标识及其对应的解析信息, 仅将该 信息用于保证本次切换用户的服务质量连续性。
本发明实施例中的解析信息可以包括源小区的各个扩展 QCI以及每个扩 展 QCI对应的优先级、 丢包率、 端到端延迟等信息的服务质量具体参数。 根 据上述解析信息对源小区的扩展 QCI进行解析即可获得某一个扩展 QCI的具 体参数, 并可进一步根据上述具体参数在目标小区建立业务承载, 还可以映 射为目标小区的扩展 QCI后由目标小区根据上述扩展 QCI建立业务承载。 另 外根据上述的解析信息还可以生成一个不同 PLMN的扩展 QCI 的对照映射 表, 由其中一个 PLMN的扩展 QCI即可获得另一个 PLMN的扩展 QCI, 映 射前后的扩展 QCI代表的服务质量最接近。
( 2 )在进行小区切换前, 基站间完成对扩展服务质量类别标识及其对应 的解析信息的交互, 在切换时, 基站间可以仅交互扩展服务质量类别标识, 或者交互扩展服务质量类别标识及其对应的解析信息。 具体实施方式如下。
( a )在小区切换前, 基站间通过 X2口消息和 /或 S 1 口消息交互扩展服 务质量类别标识及其对应的解析信息; 在小区切换时, 所述基站间通过 X2 口消息交互本基站服务小区所支持的扩展服务质量类别标识, 或者交互本基 站服务小区所支持的扩展服务质量类别标识及其对应的解析信息。
( b )在小区切换前,基站间通过 X2口消息和 /或 S1 口消息交互扩展服务 质量类别标识及其对应的解析信息; 在小区切换时, 所述基站间通过 S1 口消 息经由核心网节点交互本基站服务小区所支持的扩展服务质量类别标识,或者 交互本基站服务小区所支持的扩展服务质量类别标识及其对应的解析信息。
通过(a ) 、 ( b ) 实现方式, 基站间在小区切换前已经完成了扩展服务 盾量类别标识及其对应的解析信息的交互, 因此切换时可以只交互扩展服务 质量类别标识, 也可以交互扩展服务质量类别标识及其对应的解析信息, 以 备各个基站能够获得最新的解析信息。
本实施例中, 在小区切换前, 基站间通过 X2口消息和 /或 S 1 口消息交互 扩展服务质量类别标识及其对应的解析信息可以包括: 基站间通过 X2 口建 立消息交互本基站服务小区所支持的扩展服务质量类别标识及其对应的解析 信息; 或者基站间通过 X2 口基站配置更新消息交互本基站服务小区有更新 的扩展服务质量类别标识及其对应的解析信息。
在具体实现过程中, 在建立 X2口时, 源小区服务基站将本基站小区所 支持的扩展服务质量类别标识及其对应的解析信息包含在 X2 口建立请求消 息中, 传递到目标小区服务基站; 目标小区服务基站将本基站小区所支持的 扩展服务质量类别标识及其对应的解析信息包含在 X2 口建立响应消息中, 传递到源小区服务基站。 所述源小区服务基站和目标小区服务基站可以存储 接收到的扩展服务质量类别标识及其对应的解析信息, 以供下次切换时查询 使用; 也可以不存储接收到的扩展服务质量类别标识及其对应的解析信息, 仅将该信息用于保证本次切换用户的服务质量连续性。 在基站配置更新时, 源小区服务基站将本基站服务小区有更新的扩展服务质量类别标识及其对应 的解析信息包含在 X2 口的基站配置更新请求消息中, 传递到目标小区服务 基站; 目标小区服务基站将本基站服务小区有更新的扩展服务质量类别标识 及其对应的解析信息包含在 X2 口的基站配置更新响应消息中, 传递到源小 区服务基站。
源小区服务基站和目标小区服务基站可以存储接收到的扩展服务质量类 别标识及其对应的解析信息, 以供下次切换时查询使用; 也可以不存储接收 到的扩展服务质量类别标识及其对应的解析信息, 仅将该信息用于保证本次 切换用户的服务质量连续性。
另夕卜, 上述的在小区切换前, 基站间通过 S1 口消息交互所述扩展服务质 量类别标识相关信息, 具体可以包括: 基站间通过 S 1 口切换请求 /响应消息 经由核心网节点交互本基站服务小区所支持的扩展服务质量类别标识及其对 应的解析信息。
在具体实现过程中,上述通过 S 1口消息在基站间交互所述扩展服务质量 类别标识及其解析信息可以具体包括: 源小区服务基站将本基站服务小区所 支持的扩展服务质量类别标识及其对应的解析信息包含在 S 1 口切换请求消 息中, 发送给核心网节点, 并由核心网节点将其转发给目标小区服务基站, 目标小区服务基站将本基站服务小区所支持的扩展服务质量类别标识及其对 应的解析信息包含在 S1 口切换请求响应消息中, 发送给核心网节点, 并由核 心网节点将其转发给源小区服务基站。 这样就实现了基于核心网协助转发的 基站间扩展 QCI相关参数的交互。 当然, 针对非切换用户, 如果核心网指派 给本小区用户的 QCI为扩展 QCI, 那么可以在指派中携带该扩展 QCI对应的 解析信息, 协助基站建立该扩展 QCI对应参数的承载。 当核心网发现已经在 之前的 S1 消息中告诉过基站该扩展 QCI对应的解析信息后, 如果基站保存 了该扩展 QCI及其解析信息, 那么核心网在本次指派过程中也可以不携带该 扩展 QCI对应的解析信息。 所述源小区服务基站和目标小区服务基站可以存储接收到的扩展服务质 量类别标识及其对应的解析信息, 以供下次切换时查询使用; 也可以不存储 接收到的扩展服务质量类别标识及其对应的解析信息, 仅将该信息用于保证 本次切换用户的服务质量连续性。 在已经存储了扩展服务质量类别标识及其 解析信息的情况下, 还可以仅通过 S1口切换请求消息和 /或 S1 口切换请求响 应消息在基站间交互所述扩展服务质量类别标识。
上述 102 中, 识别切换用户使用的扩展服务质量类别标识, 并建立空口 承载, 可以具体包括: 源小区的服务基站识别切换用户使用的扩展服务质量 类别标识, 并根据存储的该扩展服务质量类别标识的解析信息获取对应的服 务质量参数信息; 然后源小区的服务基站将所述服务质量参数信息发送给目 标小区的服务基站, 具体的可以是携带在 X2 口切换请求消息中发送给目标 小区服务基站, 由目标小区的服务基站根据所述服务质量参数信息在目标小 区建立业务承载。 或者, 目标小区的服务基站根据所述扩展服务质量类别标 识相关信息识别切换用户使用的扩展服务质量类别标识, 并获取该扩展服务 质量类别标识的解析信息和对应的服务质量参数信息; 所述目标小区的服务 基站根据所述服务质量参数信息在目标小区建立业务承载。
进一步地, 上述识别扩展服务质量类别标识具体为: 如果切换用户使用 的服务质量标识是标准服务质量类别标识, 则基站确定所述切换用户使用的 服务质量标识不是扩展服务质量类别标识; 如果所述切换用户使用的服务质 量标识不是标准服务质量类别标识, 则所述基站确定所述切换用户使用的服 务 量标识是扩展服务廣量类别标识。 具体的, 上述判断用户使用的服务质 量类别标识可以为 LTE标准中定义的九种标准服务质量类别标识, 上述 QCI 标识在具体使用时分别用 1 , 2, 3 , 4, 5, 6, 7, 8, 9九个数字标识, 因此 在判断切换用户使用的 QCI标识不是上述九个数据时, 即可确认切换用户设 用的不是标准 QCI, 而是扩展 QCI。
在由 X2 口切换请求消息交互解析信息时, 除上述的将源小区服务基站 以及目标小区服务基站的服务小区的所支持的扩展 QCI全部交互共享外, 还 可以具体针对每次的切换请求, 由源小区服务基站在确定切换用户使用的服 务质量标识为源小区的扩展服务质量类别标识时, 向目标小区服务基站发送 包括所述源小区的扩展服务质量类别标识及其解析信息的 X2 口切换请求消 息; 然后由目标小区服务基站根据接收到的 X2 口切换请求消息中的解析信 息获取上述源小区的扩展服务质量类别标识对应的服务质量参数信息。 考虑 到只有在小区切换时才需要识别扩展 QCI,因此可在要求每次 X2口切换请求 消息中携带扩展 QCI 的前提下, 基站不存储不属于本基站服务小区支持的 PLMN的扩展 QCI。
另外还可以是在源小区服务基站在确定切换用户使用的服务质量标识为 源小区的扩展服务质量类别标识时, 向核心网节点发送包括所述源小区的扩 展服务质量类别标识的 S1 口切换请求消息;然后由核心网节点根据所述 展 服务质量类别标识以及存储的各个公共陆地移动网络的扩展服务质量类别标 识的解析信息获取对应的服务质量参数信息; 最后核心网节点向目标小区服 务基站发送包括所述服务质量参数信息的 S1 口切换请求消息。
如上述实施例所述, 根据存储的解析信息对扩展 QCI进行解析, 可由源 小区服务基站、 目标小区服务基站或者和核心网节点完成, 可在分布式基站 间交互不同 PLMN的扩展 QCI信息, 或者说是建立不同 PLMN的扩展 QCI 的映射对照表, 上述信息的交互可以通过公共接口消息完成或者通过专用切 换消息完成, 具体的可参照如下的具体实施例。
图 2为本发明一个具体实施例的方法流程示意图, 本实施例是通过使用 基站间公共接口信令交互解析信息, 如图 2所示, 包括如下内容。
201, 在 X2口建立请求消息(例如 X2 SETUP REQUEST )或者 X2口建 立响应消息 (例如 X2 SETUP RESPONSE ) 中交互扩展 QCI及其解析信息。 在类似于 LTE系统的扁平网络中,基站之间为分布式处理,在网络建立初期, 或者在分布式基站与相邻的基站通信前, 需要与相邻基站建立 X2 口连接, 以交互各基站所服务小区的相关信息, 例如频点、 跟踪区以及支持的 PLMN 等信息, 在本发明的实施例中, 在上述消息中还增加各个 PLMN的扩展 QCI 的解析信息, 以使得各个基站存储上述解析信息, 本实施例中建立请求消息 包含如下表 1所示的内容。
表 1
Figure imgf000011_0001
其中上述的扩展服务质量类别标识文件 (例如 Specific QCI with profile ) 即为解析信息, 能够标识出小区所支持的 PLMN的具体的服务质量参数, 具 体可以包括优先级、 端到端延迟和丢包率等信息, 上述信息不仅可以包含在 X2口建立请求消息, 还可以包含在 XI口建立响应消息中, 当有基站接收到 在上述消息中携带的解析信息后, 存储到本地基站。 LTE 系统中 X2 口切换 可如图 3所示。
202, 在本基站服务小区支持的 PLMN定义的扩展 QCI信息有更新时,同样 可以通过基站间中的公共信令进行更新, 例如在 LTE系统在可以通过基站配置 更新消息(例如 ENB CONFIGURATION UPDATE消息) 交互更新信息, 或者 是在其他相关信息中添加更新的 Specific QCI with profile信息。 本步骤可选。
203, 当用户设备在进行小区间切换时, 若用户设备使用 PLMN 自定义 的扩展 QCI, 则可由源小区服务基站识别上述的扩展 QCI, 并根据解析信息 对该扩展 QCI进行解析以获取对应的服务质量参数信息。 上述的服务质量参 数信息既可以是对应承载业务的基体服务质量参数, 也可以是对应承载业务 的目标小区的 PLMN自定义的扩展 QCI,在获得上述的服务质量参数信息后, 可将其携带在切换请求消息中发送给目标小区的服务基站。
204, 根据上述的服务质量参数信息在目标小区建立空口承载。
在上述 203中,是由源小区服务基站根据解析信息对扩展 QCI进行解析, 同样也可以是由目标小区服务基站进行解析, 即在切换请求消息中携带的是 源小区的扩展 QCI, 由目标小区服务基站根据解析信息进行解析以获取服务 盾量参数信息, 并进一步的在目标小区建立业务承载。
图 4为本发明另一具体实施例的方法流程示意图, 本实施例是切换过程 中交互解析信息, 如图 4所示, 该方法包括如下内容。
301, 用户设备在进行小区切换时, 且切换用户使用 PLMN 自定义的扩 展 QCI, 在专用切换命令中如 LTE 的切换请求消息 (例如 HANDOVER REQUEST )消息中不仅携带扩展 QCI, 还携带上述 QCI的解析信息; 携带解 析信息的切换请求消息具体可以如下表 2所示的内容。

表 3
Figure imgf000013_0001
其中上述扩展服务质量类别标识及其解析信息 (例如 Specific QCI with profile )即为扩展 QCI标识的解析信息,其中包括扩展 QCI标识、该扩展 QCI 标识对应的解析信息,还可以加上该扩展 QCI标识所属的 PLMN的 PLMNID。
302 , 目标小区服务基站在接收到切换专用信令后, 识别其中的源小区 PLMN 自定义的扩展 QCI, 以及其中的解析信息, 根据解析信息对上述 展 QCI进行解析以获得能够服务质量参数信息。
303 , 根据上述解析获取的服务质量参数信息在目标小区业务承载。依据 上述步骤建立在目标小区的业务承载, 能够保证切换前后 Qos联系性。
304, 目标小区服务基站上存储步骤 302中接收到的解析信息。 本步骤可 选。 在上述各个步骤的基础上, 能够实现在跨 PLMN切换时, 目标小区服务 基站识别切换用户使用的扩展 QCI, 也即源小区服务基站的扩展 QCI。 可通 过规定每次切换时都携带扩展 QCI 及其解析信息, 而不需要对接收到扩展 QCI 及其解析信息进行存储。 但在本步骤中也可进一步的在目标小区服务基 站上存储上述 302中接收到的解析信息, 以备后续的切换时使用。
305,在目标服务小区基站向源小区服务基站返回的切换请求响应消息中 (例如 HANDOVER REQUEST ACKNOWLEDGE )携带自己支持的所有小区 的 PLMN自定义的扩展 QCI及其解析信息。 可选地, 源小区服务基站服务小 区在接收到上述的解析信息后保存。
通过上述 304和 305即可实现各个 PLMN自定义的扩展 QCI的解析信息 的交互。 在后续的小区切换过程中, 若源小区服务基站或者目标小区服务基 站检测到已经存储了要切换的基站的支持的所有小区的 PLMN自定义的扩展 QCI 的解析信息, 则认为已经和上述基站进行过解析信息的交互, 因此在发 送的切换请求消息中可以不携带解析信息。 为了保证解析信息的准确性, 防 止扩展 QCI的解析信息有更新,也可以仍然在切换请求消息中携带解析信息。
目标小区服务基站在接收到上述的切换请求消息后, 若同时携带了扩展 QCI 和解析信息, 则才艮据解析信息进行解析, 并同时更新存储的解析信息; 若没有携带解析信息, 则调用存储的解析信息进行解析。
图 5为本发明又一具体实施例的方法流程示意图, 本实施例是依靠核心 网节点上述存储各个 PLMN的扩展 QCI的解析信息进行协助进行小区切换, 如图 5所示, 包括如下内容。
401, 源小区服务基站在进行小区切换前, 检测到切换用户使用的是 PLMN自定义的扩展 QCI, 优先使用基站与核心网之间的接口 (S1 口)进行 小区切换, 而不是用 X2 口进行小区切换, 因此向核心网节点发送携带源小 区的扩展 QCI的切换请求消息。
402, 核心网节点接收到上述携带扩展 QCI 的切换请求消息后, 选择本 次切换的目标小区, 并在目标小区与源小区的 PLMN不同时, 根据存储的各 个 PLMN的 QCI标识的解析信息对接收到的 QCI信息进行解析, 以获取对 应的服务质量参数信息, 具体的可以将源小区的扩展 QCI映射成目标小区的 扩展 QCI。
403, 核心网节点向目标小区服务基站发送包括上述服务质量参数信息 (如映射获得的目标小区的 QCI ) 的切换请求消息。
404, 根据上述服务质量参数信息 (如目标小区 QCI ) 建立业务承载。 本发明上述各个具体实施例通过在基站间交互各个 PLMN的扩展 QCI相 关信息, 在进行切换时识别切换用户使用的扩展 QCI并进行解析, 以建立业 务承载, 实现对不同 PLMN能够识别各自定义的扩展 QCI, 并能够保证在使 用自定义的 QCI情况下进行小区切换时用户 Qos感受的连续性。
