Description

一种基站侧系统获知移动终端支持能力的方法及系统 技术领域
本发明涉及移动通信领域, 尤其涉及一种全球移动通讯系统(GSM, Global System for Mobile Communications )系统中自适应的基站子系统菝知 移动终端支持能力的方法及系统。 背景技术
传统 GSM系统的网络构架如图 1所示, 传统 GSM系统的网络包括: 核心网、 基站控制器和基站, 共三层。 基站控制器和基站又可以被合称为 基站子系统。 其中, 核心网和基站控制器之间的接口称为 A接口; 基站控 制器与基站间的接口称为 Abis接口; 基站与移动终端间的接口称为 Um接 口。 核心网、 基站控制器与基站协同工作, 向移动终端提供完整的移动话 音服务功能。
随着技术的演进, 出现了扁平化的 GSM网络构架, 其接口示意图如图 2所示, 扁平化 GSM网络主要包括: 核心网和增强型基站, 共两层。 其中, 核心网与增强型基站之间的接口为 A接口; 增强型基站与移动终端之间的 接口为 Um接口; 增强型基站之间定义了新的接口, 称为增强型基站间接 口, 可以用于增强型基站与增强型基站之间进行交互。 尽管传统的 GSM系 统的网络构架和扁平化的 GSM网络构架在空中接口的行为上是相同的,但 扁平化的 GSM网络构架的优势之一是:可以与同样是扁平化的高速数据信 息包接入( HSPA, High-Speed Packet Access )的向下演进版本, 即 HSPA+、 或长期演进(LTE ) 网络采用相同的构架共语运营, 这种 GSM 与 HSPA+ 或 LTE共语运营,会导致运营商希望将有限的频谱资源在不同的无线技术, 比如 GSM、 HSPA+或 LTE等中动态共享。由此可能出现的一个应用场景为: HSPA+或 LTE 占用了大部分频语资源, GSM 占用较少部分频语资源, 但 GSM用户的数量并没有急剧减少。 这就需要 GSM网络以相对更少的频谱 资源来为这些用户提供话音服务, 因此给传统的 GSM技术带来了巨大的挑 战。
因为, 传统 GSM为时分多址( TDMA, Time Division Multi Access )系 统, 系统容量受限于时隙(TS, Time Slot )资源, 而一个 TS只能同时承载 一个全速率 ( FR, Full Rate )语音用户或者两个半速率 ( HR, Half Rate ) 语音用户。 随着技术的演进, 出现了许多提高频谱利用效率的技术, 自适 应单时隙多用户信道语音技术便是其中的一种。 自适应单时隙多用户信道 语音技术允许在一个时隙上同时承载两个 FR语音用户或者 4个 HR语音用 户,从而在不要求增加频谱资源的前提下提高了整个 GSM网络对语音用户 容量的支持。
自适应单时隙多用户信道语音技术的出现, 在使用中, 移动终端可以 通过移动终端与基站子系统之间的接口上报移动终端的自适应单时隙多用 户信道语音的支持能力, 但如果一个支持自适应单时隙多用户信道语音的 移动终端由于一些原因, 比如软件设计上的缺陷并没有上报其支持能力、 或者移动终端虽然上报了该能力, 但基站子系统想知道更为确实的、 或更 为细化的移动终端支持的自适应单时隙多用户信道语音的能力, 那么就需 要一种解决方案, 一方面, 使网络能够在移动终端不上报其自适应单时隙 多用户信道语音支持能力的情况下, 自动地检测出其自适应单时隙多用户 信道语音的支持能力; 或者, 另一方面, 移动终端虽然上报了是否具有该 能力, 但基站侧系统, 比如传统 GSM网络中的基站子系统想知道更为确实 的、 或更为细化的移动终端支持的自适应单时隙多用户信道语音的能力, 而在现有技术中并没有这样的解决方案存在, 因此, 当自适应单时隙多用 户信道语音这一新的技术被引入后, 基站子系统无法获知那些不上报自适 应单时隙多用户信道语音支持能力的移动终端的能力, 从而无法更有效地 使用该自适应单时隙多用户信道语音技术。 发明内容

一种基站侧系统获知移动终端支持能力的方法, 该方法包括以下步骤: 步骤 101、 基站侧系统对移动终端施加同频干扰。
步骤 102、 基站侧系统检测施加同频干扰后移动终端所反馈的测量报 告, 根据检测到的测量报告中的相关参数, 结合设置的相关门限阀值, 判 断并获知移动终端的自适应单时隙多用户信道语音支持能力。
这里, 相关门限阀值是基站侧系统预先设置的, 不作赘述。
这里, 区别于以上步骤 102 中直接采用判断的过程, 为了能迅速获知 移动终端的自适应单时隙多用户信道语音支持能力, 本发明还可以在加扰 之前进行预判断。 具体来说, 施加同频干扰之前, 该方法进一步包括: 基 站侧系统根据施加同频干扰前移动终端所反馈的下行测量报告中的相关参 数, 结合设置的相关阀值, 预判断移动终端的自适应单时隙多用户信道语 音支持能力。
这里, 步骤 101中的施加同频干扰, 进一步包括: 施加一轮同频干扰、 或施加多轮同频干扰。 其中, 施加多轮同频干扰时, 需设置施加同频干扰 的轮数; 所述轮数根据基站侧系统的具体应用环境和实现特性进行设置。
这里, 所述相关参数具体为: 表征移动终端的干扰处理能力的参数。 需要指出的是: 预判断中所涉及到的下行测量报告、 和判断过程中所 涉及到的测量报告, 针对移动终端侧而言都是测量报告, 区别仅仅在于是 加扰前反馈的, 还是加扰后反馈的测量报告。 同样地, 针对基站侧而言, 都是测量报告, 区别仅仅在于是加扰前检测到的, 还是加扰后检测到的测 量报告。
这里, 施加多轮同频干扰时, 该方法进一步包括: 无论是针对预判断 过程还是判断过程而言, 只要有一次的判断结果能判断出移动终端具有自 适应单时隙多用户信道语音支持能力, 就可以确定该移动终端为: 具有自 适应单时隙多用户信道语音支持能力的移动终端。
或者, 施加多轮同频干扰时, 该方法进一步还可以包括另一种最强限 定原则的实现方式, 即: 无论是针对预判断过程还是判断过程而言, 每一 轮施加同频干扰后的判断结果中, 只有每次的判断结果都能判断出移动终 端具有自适应单时隙多用户信道语音支持能力, 才可以确定该移动终端为: 具有自适应单时隙多用户信道语音支持能力的移动终端。
以下对预判断过程和判断过程分别阐述。
第一阶段: 预判断过程。
预判断具体包括以下实现方式中的至少一种:
第一: 对 N个最近连续或离散的下行测量报告中, 接收信号质量的参 数值求均值; 当求得的均值小于设置的门限阔值 TO时, 预判断出移动终端 为具有自适应单时隙多用户信道语音支持能力的移动终端。
需要指出的是, 无论预判断还是判断, 实际上都是判断出当前移动终 端所具有自适应单时隙多用户信道语音支持能力的可能性, 即: 预判断出 移动终端可能为具有自适应单时隙多用户信道语音支持能力的移动终端, 不做赘述。
第二: 对 N个最近连续或离散的下行测量报告中, 接收信号质量的参 数值求标准差; 当求得的标准差小于设置的门限阔值 T1时, 预判断出移动 终端为具有自适应单时隙多用户信道语音支持能力的移动终端; 其中, 所 述接收信号质量为:接收信号质量的均值小于设置的门限阔值 TO的下行测 量报告中的接收信号质量。
第三: 对 N个最近连续或离散的下行测量报告中, 接收信号强度的参 数值求均值; 对含有接收信号强度的均值小于设置的门限阔值 T2的测量报 告中, 接收信号质量的参数值求均值和标准差; 当求得的标准差小于设置 的门限阔值 T1时,预判断出移动终端为具有自适应单时隙多用户信道语音 支持能力的移动终端; 其中, 求接收信号质量的标准差时采用的接收信号 质量为:接收信号质量的均值小于设置的门限阔值 TO的下行测量报告中的 接收信号质量。
第二阶段: 判断过程。
判断具体包括以下实现方式中的至少一种:
第一: 对 N个最近连续或离散的测量报告中, 接收信号质量的参数值 求均值; 当求得的均值小于设置的门限阔值 T3时, 判断出移动终端为具有 自适应单时隙多用户信道语音支持能力的移动终端。
第二: 对 N个最近连续或离散的测量报告中, 接收信号质量的参数值 求标准差; 当求得的标准差小于设置的门限阔值 T4时, 判断出移动终端为 具有自适应单时隙多用户信道语音支持能力的移动终端; 其中, 所述接收 信号质量为:接收信号质量的均值小于设置的门限阔值 T3的测量报告中的 接收信号质量。
第三: 对 N个最近连续或离散的测量报告中, 接收信号强度的参数值 求均值;对含有接收信号强度的均值小于设置的门限阔值 T5的测量报告中, 接收信号质量的参数值求均值和标准差; 当求得的标准差小于设置的门限 阔值 T4时,判断出移动终端为具有自适应单时隙多用户信道语音支持能力 的移动终端; 其中, 求接收信号质量的标准差时采用的接收信号质量为: 接收信号质量的均值小于设置的门限阔值 T3 的测量报告中的接收信号质 量。
综上所述,本发明的方案是一种 GSM系统中在自适应单时隙多用户信 道语音模式下, 基站侧系统自适应地、 精确地获知移动终端干扰抑制能力 的实现方案。本文的 GSM系统包括传统的 GSM系统,也包括扁平化的 GSM 系统, 不作赘述。 采用本发明, 在 GSM网络中, 网络能够在移动终端不上 报自适应单时隙多用户信道语音支持能力的情况下; 或者, 移动终端虽然 上报了是否具有该能力, 但基站侧系统想知道更为确实的、 或更为细化的 移动终端支持的自适应单时隙多用户信道语音的能力的情况下, 自动检测 并判断出移动终端支持的自适应单时隙多用户信道语音的能力。 从而, 在
GSM网络使用自适应单时隙多用户信道语音技术后, 能够实现在不要求增 加频谱资源的前提下, 更好的提高整个 GSM网络对语音用户容量的支持, 其原因在于: 由于现有技术中, 基站侧系统不能获知移动终端支持的该能 力, 因此, 在使用自适应单时隙多用户信道语音技术后, 基站侧系统无法 把合适的信道分配给用户, 从而导致信道利用率低; 而采用本发明, 由于 基站侧系统能够获知移动终端支持的该能力, 因此, 就可以精确地分配合 适的信道给用户, 也就是说, 把能力匹配最适合的用户放在一个信道中, 大大提高了信道利用率。
以传统的 GSM系统为例, 此时的基站侧系统为基站子系统, 本发明主 要包括以下内容:
基站子系统通过以下两个阶段, 来实现对自适应单时隙多用户信道语 音支持能力的自动检测功能。 第一阶段是针对加扰后的第二阶段而言的, 第一阶段是预判断阶段, 而加扰后的第二阶段是精确判断的阶段, 以下分 别阐述。
第一阶段: 基站子系统可以通过对下行测量报告中的表征移动终端干 扰处理能力的相关参数进行分析, 来判断出移动终端的自适应单时隙多用 户信道语音支持能力。 其中, 表征移动终端干扰处理能力的相关参数包括: 接收信号质量、 或接收信号强度等。
这里, 第一阶段是先预判断哪些移动终端的干扰抑制能力较强, 这些 干扰抑制能力较强的移动终端, 有可能就是支持自适应单时隙多用户信道 语音的移动终端。
第一阶段可以根据不同的策略选择是否需要, 比如在某些需要情况下, 移动终端没有上报、 或只上报了很少的测量报告, 而基站子系统想立即获 知其是否具有自适应单时隙多用户信道语音干扰抑制能力, 可以选择跳过 第一阶段的预判断, 让这些移动终端直接进入第二阶段进行判别; 也可以 根据这些数目较少的测量报告进行预判断。
第二阶段: 基站子系统给这些被预判断出干扰抑制能力较强的移动终 端施加 X轮同频干扰, 施加的方式是先加一轮同频干扰, 施加该轮同频干 扰的功率强度和持续时间可以根据基站子系统的策略来设置, 然后分析施 加同频干扰期间的一个或多个下行测量报告中的接收信号质量, 接收信号 强度等相关参数, 如果这些参数优于一个设定的门限阔值, 则再加一轮同 频干扰。 同样的, 施加该同频干扰的功率强度和持续时间, 可以根据基站 子系统的策略来设置, 然后分析下施加该轮同频干扰期间的一个或多个下 行测量报告中的接收信号质量, 接收信号强度等相关参数, 如果这些参数 优于一个设定的门限阔值, 再加一轮同频干扰, 依次类推, 直到施加的同 频干扰数等于预设的 X轮, 其中 X的值可以等于 1、 或 2、 或根据基站子系 统的具体应用环境和实现特性进行定义。
针对上述 "根据基站子系统的策略来设置" 中的该策略而言, 举例如 下:
一, 对于功率的策略: 可以在第一轮施加同频干扰时, 施加同频干扰 的功率强度与信号功率相同; 而第二轮施加同频干扰时, 施加同频干扰的 功率强度为信号功率的两倍; 第三轮施加同频干扰时, 施加同频干扰的功 率强度为信号功率的三倍等等。 也可以在第一轮施加同频干扰时, 施加同 频干扰的功率强度与信号功率相同; 第二轮施加同频干扰时, 施加同频干 扰的功率强度也与信号功率相同; 第三轮施加同频干扰时, 施加同频干扰 的功率强度也与信号功率相同等等。
二, 对于持续的时间策略: 可以是 104个 TDMA帧。 也可以是 10个 TDMA帧。 还可以是 8个 bursts或 32个 Burst等等。 持续的时间策略还可 以包括连续施加或间隔施加同频干扰。
基站子系统可以通过分析施加了同频干扰的下行测量报告中的接收 信号质量, 接收信号强度等相关参数, 结合基站子系统预先设置的各种相 关门限, 来自适应地判断移动终端的自适应单时隙多用户信道语音能力。 具体的, 移动终端的自适应单时隙多用户信道语音能力的判断, 根据基站 子系统的策略来实现。
基站子系统施加同频干扰的方式可以是多样化的, 比如该方式可以连 续数个突发脉冲, 施加该同频干扰、 或是可以离散的, 即不连续的数个突 发脉冲, 施加该同频干扰。
基站子系统施加的同频干扰的调制方式也可以是多样化的, 比如该同 频干扰是一个采用高斯滤波最小频移键控 (GMSK , Gaussian filtered Minimum Shift Keying )调制的与被测信号相位相同的干扰信号, 或是一个 与被测信号相位相差 τ/2的 GMSK调制信号, 或是可以体现为采用与被测 信号组成的一个自适应单时隙多用户信道语音调制信号, 基站子系统可以 按自己的策略采用不同的方式。
以下对本发明进行举例阐述。
方法实施例: 基站侧系统为基站子系统、 移动终端处于专用模式的情 况。 这里需要说明的是: 终端通常有两种模式, 一种为空闲模式, 另一种 为专用模式, 空闲模式指手机未处于空闲状态, 而专用模式表示手机处于 非空闲状态。
如图 3 所示, 基站子系统希望获知移动终端的自适应单时隙多用户信 道语音能力时发起以下步骤:
步骤 301、 通话过程中移动终端上报下行测量报告信息。
这里, 下行测量报告信息中包括: 接收信号质量、 接收信号强度等信 息。
这里, 假设此时某个移动终端已经连续上报了 4个下行测量报告, 其 中包含了接收信号质量(Q0、 Ql、 Q2、 Q3 )、 以及接收电平(P0、 Pl、 P2、 P3 )。
步骤 302、基站子系统根据移动终端上报的下行测量报告信息, 预判断 移动终端的自适应单时隙多用户信道语音能力, 找出可能具有自适应单时 隙多用户信道语音支持能力的移动终端。
这里, 针对第一阶段预判断过程的具体实现方式而言, 根据基站子系 统的具体应用环境和实现特性有多种实现方案, 以下分别阐述。
实现方案一: 对 N个连续最近或离散的测量报告中的接收信号质量参 数值求均值, 若均值小于特定设置的门限阔值 TO, 比如小于 2 , 就认为该 移动终端的干扰抑制能力强, 可能是具有自适应单时隙多用户信道语音支 持能力的移动终端。 该实现方案一的示意图如图 4所示, 图 4为第一阶段 中预判断移动终端能力的一示例图, 此时接收质量的均值 < TO, 即: Mean ( [Q0、 Ql、 Q2、 Q3] ) < 2。
实现方案二: 对 N个连续最近或离散的、 接收信号质量小于特定设置 的门限阔值 TO,比如小于 2的测量报告中的接收信号质量参数值求标准差, 若标准差值小于特定设置的门限阔值 T1 , 比如小于 0.05 , 就认为该移动终 端的干扰抑制能力强, 可能是具有自适应单时隙多用户信道语音支持能力 的移动终端。 该实现方案二的示意图如图 5所示, 图 5为第一阶段中预判 断移动终端能力的一示例图, 包括:接收质量的均值< ^), 即: Mean ( [Q0、 Ql、 Q2、 Q3] ) < 2; 接收质量的标准差 < T1 , 即: Std ( [Q0、 Ql、 Q2、 Q3] ) < 0.05。
实现方案三: 结合下行测量报告中的接收信号质量和接收信号强度一 起进行判断, 比如只对含有接收信号强度小于某个门限阔值 T2的测量报告 中的接收信号质量参数值求均值或标准差, 再进行后续判断。 另外, 基站 子系统设置需要施加的 X轮同频干扰的参数值, X的值可以等于 1或 2或根 据基站子系统的具体应用环境和实现特性进行定义。 该实现方案三的示意 图如图 6所示, 图 6为第一阶段中预判断移动终端能力的一示例图, 包括: 接收功率的均值<丁2, 即: Mean ( [P0、 Pl、 P2、 P3] ) < T2; 接收质量的 均值 < Τ0, 即: Mean ( [Q0、 Ql、 Q2、 Q3] ) < 2; 接收质量的标准差 < T1 , 即: Std ( [Q0、 Ql、 Q2、 Q3] ) < 0.05。
需要指出的是: 在实际具体应用中, 可以选择只单一的用一种实现方 案来进行预判断、 或者组合使用多种实现方案进行预判断, 比如选择实现 方案二与实现方案三进行组合的预判断。 这种组合判断中各实现方案的判 断顺序, 本文不做限定。
如图 7所示为第一阶段中预判断移动终端能力组合实现方案的一示例 图, 包括: 先使用以上实现方案二, 再结合实现方案三的组合实现方案; 如图 8所示为第一阶段中预判断移动终端能力组合实现方案的另一示例图, 包括: 先使用以上实现方案三, 再结合实现方案二的组合实现方案。
步骤 303、基站子系统对可能具有自适应单时隙多用户信道语音支持能 力的移动终端施加一轮同频干扰。
这里, 施加该同频干 ·ί尤的功率可以有多种选择, 比如, 一种选择是: 与信号等功率强度的同频干扰; 另外一种选择是: 比信号功率高 2-3dB 的 同频干扰。
步骤 304、 持续同频干扰一段时间。
这里, 持续该同频干扰的方式也可以有多种选择, 比如, 可以是一个 突发脉冲的时间; 也可以是连续数个突发脉冲的时间; 也可以是离散的, 即不连续的数个突发脉冲的时间。
这里, 在本方法实施例中, 是经过数个连续的突发脉冲, 移动终端在 这期间上报一个或数个下行测量报告。 比如, 该同频干扰连续干扰 4个测 量报告, 每个测量报告施加时间为连续的 26个突发脉冲。 该移动终端在这 期间又上报了 4个下行测量报告, 其中包含了接收信号质量(Q4、 Q5、 Q6、 Q7 )、 以及接收电平 (P4、 P5、 P6、 P7 )。
步骤 305、基站子系统通过分析施加了同频干扰后的测量报告, 结合预 先设置的自适应单时隙多用户信道语音干扰抑制能力的门限阔值, 来判断 该移动终端的自适应单时隙多用户信道语音支持能力。
这里, 根据基站子系统的具体应用环境和实现特性, 对测量报告中的 相关参数, 比如接收信号质量, 接收信号强度等, 结合预先设置的自适应 单时隙多用户信道语音干扰抑制能力的门限阔值, 来进行判断。 其中, 这 种自适应单时隙多用户信道语音干扰抑制能力的门限阔值, 可以有多个。
这里, 针对第二阶段判断过程的具体实现方式而言, 根据基站子系统 的具体应用环境和实现特性有多种实现方案, 以下分别阐述。
实现方案 1 : 通过对 N个连续最近或离散的测量报告中的接收信号质 量参数值求均值, 若均值小于特定设置的门限阔值 T3 , 比如小于 2, 就认 为该移动终端的干扰抑制能力强, 可能是具有自适应单时隙多用户信道语 音支持能力的移动终端。 该实现方案 1的示意图如图 9所示, 图 9为第二 阶段中判断移动终端能力的一示例图,此时接收质量的均值 < T3 ,即: Mean ( [Q4、 Q5、 Q6、 Q7] ) < 2。
实现方案 2: 对 N个连续最近或离散的、 接收信号质量小于特定设置 的门限阔值 T3 ,比如小于 2的测量报告中的接收信号质量参数值求标准差, 若标准差值小于特定设置的门限阔值 T4, 比如小于 0.05 , 就认为该移动终 端的干扰抑制能力强, 可能是具有自适应单时隙多用户信道语音支持能力 的移动终端。 该实现方案 2的示意图如图 10所示, 图 10为第二阶段中判 断移动终端能力的一示例图, 包括:接收质量的均值<丁3 , 即: Mean ( [Q4、 Q5、 Q6、 Q7] ) <2; 接收质量的标准差 <T4, 即: Std ( [Q4、 Q5、 Q6、 Q7]) <0.05。
实现方案 3:结合下行测量报告中的接收信号质量和接收信号强度一起 进行判断, 比如只对含有接收信号强度小于某个预设定门限阔值 T5的测量 报告中的接收信号质量参数值求均值或标准差, 再进行后续判断。 该实现 方案 3的示意图如图 11所示, 图 11为第二阶段中判断移动终端能力的一 示例图, 包括: 接收功率的均值<丁5, 即: Mean ([P4、 P5、 P6、 P7] ) < T5; 接收质量的均值<丁3, 即: Mean ([Q4、 Q5、 Q6、 Q7] ) <2; 接收质 量的标准差 <T4, 即: Std ([Q4、 Q5、 Q6、 Q7] ) <0.05。
需要指出的是: 在实际具体应用中, 可以选择只单一的用一种实现方 案来进行判断,或者组合使用多种实现方案进行判断, 比如选择实现方案 2 与实现方案 3 进行组合的判断。 这种组合判断中各实现方案的判断顺序, 本文不做限定。
如图 12 所示为第二阶段中判断移动终端能力组合实现方案的一示例 图, 包括: 先使用以上实现方案 2, 再结合实现方案 3的组合实现方案; 如 图 13所示为第二阶段中判断移动终端能力组合实现方案的另一示例图, 包 括: 先使用以上实现方案 3, 再结合实现方案 2的组合实现方案。
需要指出是: 上述步骤 302中的阔值 TO, Tl, T2与本步骤 305中的阔 值 T3, T4, T5之间的关系是: TO可以等于 T3, 也可以不等于 T3; T1可 以等于 T4, 也可以不等于 T4; T2可以等于 T5, 也可以不等于 T5。 具体的 取值, 本文不做限定。
步骤 306、 基站子系统检查是否达到预设的施加 X轮同频干扰的要求, 如果未达到, 则重复执行步骤 303〜步骤 305; 如果达到, 则执行步骤 307。
步骤 307、对于上述各轮施加同频干扰后的结果进行处理, 以最终判断 出该移动终端的自适应单时隙多用户信道语音能力。 针对本步骤 307 中的处理而言, 处理的实现方案根据基站子系统的具 体应用环境和实现特性有多种实现方式。 比如: 一种实现方式是采取最大 可能方式, 即: 每一轮施加同频干扰后的结果中, 只要有一次的结果是认 为该移动终端具有自适应单时隙多用户信道语音能力, 就认为该移动终端 具有自适应单时隙多用户信道语音能力。 或者, 另一种实现方式是采用最 强限定原则方式, 即: 每一轮施加同频干扰后的结果中, 只有每次的结果 认为该移动终端是具有自适应单时隙多用户信道语音能力的。
需要说明的是, 在不背离所附权利要求阐明的精神和范围的情况下, 可以对元件或模块的功能和布置进行各种改变。
例如, 作为一种实现方式, 本发明提出的方案, 除了用在判断移动终 端是否具有自适应单时隙多用户信道语音能力外, 还可以用在判断移动终 端是否具有单天线干扰抑制消除能力。
另外, 考虑到自适应单时隙多用户信道语音技术的不断发展和演进, 技术的不断成熟, 移动终端的自适应单时隙多用户信道语音能力也会出现 不同, 不同移动终端的自适应单时隙多用户信道语音能力会不同, 比如有 些移动终端仅支持初级的自适应单时隙多用户信道语音技术, 可以定义为 技术等级 1 ,而有些移动终端支持较高级的自适应单时隙多用户信道语音技 术, 可以定义为技术等级 2, 以此类推。 本发明提出的方案还可以用在: 基 站子系统自适应地判断移动终端是上述的那类终端, 可以通过选择不同轮 次, 对每轮次结果判断的阔值 T3 , T4, T5等采用不同的参数值来实现。
