Description

保障分组业务服务质量的方法、 系统及装置 技术领域
本发明涉及无线通信的分组数据业务处理技术， 尤其涉及一种保障 分组业务服务质量的方法、 系统及装置。 发明背景
在目前的分组通信处理系统中， 通信用户终端在进行分组业务的过 程中， 针对不同的业务种类要求通信网络提供不同的服务质量（Qos， Quality of Service ), 即分配不同质量的网络资源（主要是网络带宽）。 例 如： 用户在使用终端观看足球比赛时， 要求网络保证一定的带宽质量， 比如， 至少要求 100kbps通讯带宽。
一^:而言， 终端在进行分组业务之前， 会与网络进行 Qos的协商。 在 Qos协商过程中， 终端向网络提出 Qos要求， 网络根据自身的资源情 况， 给终端反馈一个网络能够提供的 Qos。 例如图 1为现有技术中当网 络能够满足终端的 Qos时的分組业务接入流程图。 参见图 1 , 终端的接 入过程包括：
步骤 101 : 终端向网络侧的源小区 （即当前为终端服务的小区）发 送资源请求， 其中携带其要求的服务质量信息。
步骤 102: 网络侧的源小区根据终端要求的服务质量， 分配上行无 线资源， 其无线资源满足终端要求的服务质量， 并通过资源指配消息通 知终端所指配的无线资源。
步骤 103 : 终端在源小区所分配的无线资源上发送上行数据块。 步骤 104:终端在源小区所分配的无线资源上继续发送上行数据块。 目前， 因为网络资源的限制， 网络侧可能无法保证协商得到的 Qos 或者终端要求的 Qos。 例如， 终端在发生了小区重选或者切换后， 目标 小区无法满足终端要求的 Qos。 这种情况下， 现有技术一般采用以下三 种处理方式：
1 )降低优先级： 通过降低 Qos为用户终端继续提供所请求的服务。
2 )抢占： 高优先级终端抢占低优先级终端的资源， 保证高优先级 终端的 Qos。
3 )拒绝： 在无法保证终端要求的 Qos 时， 只能拒绝向终端提供服 务。
然而， 通过网络降低 Qos优先级而为终端继续提供服务的方案， 在 某些情况下是不可以接受的。 例如， 用户在使用移动终端看足球比赛过 程中， 视频分组业务至少要求 100kbps的带宽； 用户在移动过程中发生 ： 了小区重选， 重新选择到了新的小区， 而新小区的资源有限， 不能满足. lOOkpbs的带宽要求； 这时， 假设网络选择降低 Qos为终端继续提供服 务的方式， 比如只提供 60kbps的通信带宽， 这时， 用户必然会因为无法 正常收看足球比赛而终止观看。 原因在于， lOOkpbs 是能正常观看足球 比赛的最低要求， 也就是用户能够接受服务质量的最低要求， 一旦网络 不能到达这种要求， 通过降低服务质量来继续为用户提供服务是不可行 的。
如果采用抢占的方式来保证高优先级终端的 Qos， 则会使低优先级 终端的业务无法保证， 从而降低整体的用户满意度。
图 2为现有技术中网络无法满足终端的 Qos时的分组业务接入流程 图。 参见图 2, 包括：
步骤 201 : 终端向网络侧的源小区 （即当前为终端服务的小区）发 送资源请求， 其中携带其要求的服务质量信息。
步骤 202、 源小区根据自身资源情况判定无法满足终端的服务质量 要求， 向终端发送资源拒绝消息。
上述现有技术的处理方式没有最大限度的保证用户终端要求的服务 质量。 当 2G/3G网络共存时， 终端从 3G小区切换 /重选到 2G小区时， 发生业务中断的情况会更多。 发明内容
本发明实施例提供了一种保障分组业务服务质量的方法、 系统及装 置， 以提高分组业务的服务质量。
本发明实施例的主要技术方案包括：
本发明实施例提供了一种保障分组业务服务质量的方法， 当终端请 求源小区分配终端的分组业务资源时， 包括： 如果源小区的资源不能满 , 足终端的服务质量要求， 则请求源小区的相邻小区为终端分配资源。
本发明实施例还提供了一种保障分组业务服务质量的系统， 其包 括： 终端、 第一基站和第二基站， 第一基站为终端的源小区的基站， 第 二基站为源小区的相邻小区的基站， 其中， 终端用于请求第一基站分配 分组业务资源， 第一基站用于当本小区资源不能满足终端的服务质量要 求时请求第二基站分配资源。
本发明实施例又提供了一种保障分组业务服务质量的装置， 包括： 第一模块， 用于在被终端请求为终端分配分组业务资源时判断本小区资 源是否满足终端的服务质量要求； 第二模块， 用于在第一模块判断本小 区资源不能满足终端的服务质量要求时请求本小区的相邻小区为终端 分配资源。
本发明实施例中， 在小区由于自身资源限制无法为终端的分组业务 提供符合 Qos要求的资源时， 将终端指配到其他相邻小区， 由相邻小区 才艮据自身的资源情况处理分组业务。 采用本发明实施例可以最大限度地 保证终端的 Qos要求， 提高通信网络对分组业务的服务质量， 相对于现 有技术能减少由于不能满足用户的服务质量要求而导致的分组业务中 断。 附图简要说明
图 1为现有技术中当网络能够满足终端的服务质量时的分組业务接 入流程图。
图 2为现有技术中网络无法满足终端服务质量时拒绝服务的分组业 务接入流程图。
图 3为依据本发明实施例的保障分组业务服务质量的流程图。 实施本发明的方式
下面通过具体实施例和附图对本发明 进一步详细说明。 '： 本发明实施例提供了一种保障分組业务服务质量的方法， 包括： 当 收到分组业务资源请求的小区的判定其自身资源不能满足所请求的分 组业务服务质量要求时， 将请求分组业务的终端指配到其相邻小区， 由 源小区的相邻小区继续处理终端请求的分组业务。
本发明实施例适用于对服务质量有要求的分组业务处理过程， 例如 移动终端接入网络的过程， 移动终端分组业务数据的传输过程中， 以及 移动终端的分组切换过程等等。 本文的实施例应用在终端接入网络的过 程中。 而应用于其它过程中的各个本发明实施例， 与本文实施例的原理 相同， 本文对这些实施例不再详述。
图 3为依据本发明实施例的保障分组业务服务质量的流程图。 本实 施例中， 在终端接入过程中当源小区无法满足终端的服务质量要求时将 终端接入到目标小区。其中，源小区为当前与用户终端进行通信的小区， 目标小区为源小区所选的一个相邻小区。 处理流程具体包括：
步骤 301 : 终端在源小区 （当前为终端服务的小区）发起分组业务 的资源请求， 其中携带所需的服务庸量要求 （Qos )信息。
步骤 302:在源小区判定自身无法满足终端所请求的分组业务的 Qos 时， 从其相邻小区中选择一个小区作为目标小区， 将包括服务质量要求 信息的资源请求发送给所选目标小区。
步骤 303 : 目标小区收到源小区发送的资源请求， 根据其中的服务 质量要求信息为终端分配本小区的无线资源。
具体的，本步骤中 ,如果目标小区自身资源情况满足服务质量要求， 则目标小区为终端指配满足服务质量要求的无线资源， 按照所指配的资 源为终端的分组业务提供服务资源， 即按照资源请求的请求路径向源小 区返回携带所分配资源信息的资源指配消息（如果是经过多个小区转发 来的资源请求，则再按照原路径转发回去：)，并执行步骤 304至步骤 306; 如果目标小区的自身资源情况不能满足服务质量要求， 则拒绝终端的分 组业务（即向源小区返回资源请求拒绝消息， 源小区再拒绝终端的请 求）， 或者目标小区将携带服务质量要求信息的资源请求发送给本目标 小区的相邻小区之一， 收到资源请求的相邻小区重新执行步骤 303。
此处， 如果目标小区不能满足服务质量要求， 并向其相邻的源小区 发送资源请求， 即源小区又接收到目标小区返回的关于同一终端的资源 请求， 则源小区会拒绝资源请求对应的终端的分组业务。
步骤 304: 源小区收到目标小区的资源指配消息， 向终端发送资源 指配消息， 其中包含目标小区所分配的无线资源， 以通知终端接入到目 标小区。
步驟 305: 终端收到源小区的资源指配消息， 发现指配了目标小区 的资源， 则进入目标小区， 监听目标小区所分配的资源， 在所分配的资 源上发送上行数据块。
步骤 306: 终端继续监听目标小区所分配的资源， 在所分配的资源 上继续发送上行数据块。
在上述步骤 302中， 源小区可以判定其相邻小区都能满足终端的服 务质量要求， 此时需从相邻小区中任选一个作为目标小区即可； 源小区 也可以通过相关的信息判定某一相邻小区可以或可能满足终端的服务 质量要求， 并选择某一可以或可能满足服务质量要求的相邻小区作为目 标小区。 对于后一种处理方式， 主要分三种情况：
第一种情况， 源小区获取其相邻小区的资源情况， 根据资源情况从 相邻小区中选择一个可以满足服务质量要求的相邻小区， 再将资源请求 发送给所选的相邻小区。 此处， 选择相邻小区的具体方式可以为： 根据 资源情况对相邻小区进行排序， 从中选择资源情况最好的相邻小区。 源 'J、区获取其相邻小区的资源情况信息的具体方式至少可以有以下几种： : a) 源小区向相邻小区发送获取资源情况的请求，相邻小区收到获取资源 情况的请求后返回自身的资源情况信息給源小区； b) 小区之间可以定时 或者自身资源发生变化时向其相邻小区发送自身的资源情况信息， 源小 区根据其相邻小区定时发送来的资源情况信息获知相邻小区的资源情 况； c) 如果源小区和其相邻小区在同一个基站控制器内， 则源小区可以 从基站控制器中获取其相邻小区的资源情况信息。
第二种情况， 源小区从终端上报的各小区的测量报告（在终端接入 的时候上报） 中获取其相邻小区的传输质量， 选择传输质量最好的相邻 小区， 再将资源请求发送给所选的相邻小区。
第三种情况， 源小区获取其相邻小区的资源情况， 从终端上报的各 小区的测量报告中获取其相邻小区的传输质量， 根据资源情况和传输质 量从相邻小区中选择既可以满足服务质量要求又具有较高传输质量的 相邻小区， 再将资源请求发送给所选的相邻小区。 这里， 可设定所有满 足服务质量要求的小区中传输质量最高的小区为具有较高传输质量的 小区。
在步骤 303中， 目标小区在选择相邻小区作为新的目标小区时也可 以具体采用上述源小区选择相邻小区作为目标小区的方法。
本发明实施例还提出了一种保障分组业务服务质量的系统， 其至少 包括： 终端、 源小区的基站 （可称为第一基站）， 此系统还可进一步包 括： 源小区的相邻小区的基站 （可称为第二基站）， 此系统也可包括终 端和三个以上的基站， 包括： 源小区的基站、 源小区的相邻小区的基站、 至少一个源小区的相邻小区的相邻小区的基站（可称为第三基站）。
当终端请求第一基站为其分配分组业务资源时， 第一基站判断源小 区的资源是否能满足终端的服务质量要求， 若不能满足， 则请求第二基 站为终端分配资源。
进一步地， 被请求为终端分配资源的基站中除第一基站以外的每一 基站（即第二基站 第三基站）还可判断本小区资源情况是否满足服务 质量要求， 若满足， 则为终端分配资源， 使用所分配的资源为终端提供 服务； 若不满足， 则拒绝终端的请求， 或者倩求本小区的相邻小区的基 站（即第三基站） 为终端分配资源。
本发明实施例一种保障分组业务服务质量的装置， 包括： 第一模块， 在被请求为终端分配分组业务资源时判断本小区资源是否满足终端的 服务质量要求； 第二模块， 在第一模块判断本小区资源不能满足所述终 端的服务质量要求时请求本小区的相邻小区为终端分配资源。 这里， 此 装置可为终端源小区的基站， 此时第一模块在终端向其请求分配资源时 判断本小区资源是否满足终端的服务质量要求。
考虑到作为源小区的相邻小区也可以在本小区资源不能满足终端 的服务质量要求时请求本小区的相邻小区为终端分配资源， 上述装置也 可作为源小区的基站以外的基站， 此时第一模块用于在本小区的相邻小 区请求为终端分配资源时判断本小区资源是否满足终端的服务质量要 求。
上述系统及装置的具体实现原理在前述流程中已详细阐述， 本文不 再赘述。
以上所述， 仅为本发明较佳的具体实施方式， 但本发明的保护范围 并不局限于此， 任何熟悉此技术的人在本发明所揭露的技术范围内， 可 轻易想到的变化或替换， 都应涵盖在本发明的保护范围之内。
