其中, HSPA+特性指 64 QAM、 MIMO、 DC HSDPA或 DB DC HSDPA等。 本实施例中, 上述终端支持的 HSPA+特性可以通过下述方式获取: 网络侧设备接 收终端上报的 RRC (Radio Resource Control, 无线资源控制)层消息, 从 RRC层消息 解析出终端支持的 HSPA+特性。 当终端支持上述多种 HSPA+特性中的一个或者多个 时, 将会在 RRC消息中包含对应的信元, 用于通知接入网络该终端支持哪些 HSPA+ 特性。 在确定是否存在多种 HSPA+特性相互匹配时,可以将终端支持的 HSPA+特性与自 身支持的 HSPA+特性逐一进行比对,如果相同,则确定网络侧设备与终端的该 HSPA+ 特性是相互匹配的, 当终端和网络都支持某一 HSPA+特性, 就认为该特性是可以配置 给终端进行使用的。 通过这种比对方式, 将终端和网络侧设备所支持的 HSPA+特性均 进行比较后, 将能够确定是否存在多种 HSPA+特性相互匹配, 此时可以将这多种 HSPA+特性列在一个表中, 用以后续使用。 如果通过上述比对, 如果终端和网络侧设备只存在一种 HSPA+特性匹配时, 则可 以直接确定将该 HSPA+特性配置给终端, 无需进行下面的选择操作。 步骤 S104, 网络侧设备根据当前网络状态,从多种 HSPA+特性中选择性能增益最 大的 HSPA+特性; 本实施例中的网络状态包括网络负荷和 /或信道质量等, 该信道质量可以用终端上 报的 CQI (Channel Quality Indicator, 信道质量指示) 或者 Ec/No (接收的每码片能量 与噪声功率密度之比) 等指标进行衡量。 HSPA+特性可以根据预定的算法选择性能增 益最大的。 该预定算法根据不同的 HSPA+特性受不同因素影响, 例如由于终端或者网 络能力约束, 导致不能同时使用 DC HSDPA和 MIMO特性的情况下, 当网络负荷较 高时, 由于 MIMO特性带来的吞吐量提升高于 DC HSDPA带来的吞吐量增益, 这时 候就选择配置使用 MIMO特性; 当信道质量较差时, 由于使用 DC HSDPA产生的吞 吐量增益高于使用 MIMO特性产生的增益,因此这种情况下可以选择使用 DC HSDPA, 对于其他 HSPA+特性也可以根据具体受影响的因素, 采用上述类似方式进行选择。 本实施例中的性能增益可以是体现在网络吞吐量或用户数据速率等指标的参数。 步骤 S106, 网络侧设备将上述选择的 HSPA+特性配置给该终端。 在进行具体配置时, 网络侧设备可以通过 RRC配置消息将选择的 HSPA+特性通 知给终端。 这样, 后续终端和网络侧设备将使用该 HSPA+特性进行数据的传输。 本实施例通过网络侧设备根据当前网络状态, 从多种 HSPA+特性中选择性能增益 最大的 HSPA+特性,解决了现有技术中为终端配置的 HSPA+特性导致性能增益效果不 理想的问题, 有效提高网络容量, 并改善用户感受。 此外, 考虑到网络状态会时常发生变化, 例如: 当终端由于移动等原因, 导致其 所处位置信道质量发生变化, 或者网络负荷等因素发生变化; 为了增强终端与网络侧 数据传输的可靠性, 本实施例中的上述方法还包括: 网络侧设备监测到网络状态发生 变化时,重新从上述多种 HSPA+特性(即上述终端与网络侧设备相匹配的 HSPA+特性) 中再次选择性能增益最大的 HSPA+特性配置给该终端。该方式可以达到根据网络运行 实际状况和终端所处的不同位置时不同的信道质量等因素, 动态选择不同条件下增益 最大的 HSPA+特性, 从而有效提高网络容量, 并改善用户感受。 本实施例的上述方法可以在 WCDMA和 TDSCDMA系统中应用,针对上述 HSPA+ 特性的配置方法, 下面以 WCDMA系统为例, 详细说明具体的 HSPA+特性动态选择 配置的过程。 实例 1 下面结合附图 2对 WCDMA系统中 R8或 R8以上版本支持 64QAM+MIMO特性 的终端 (UE) 接入到既支持 64QAM, 也支持 MIMO的 R7或以上版本网络中处理过 程进行描述, 该过程包括以下描述: 步骤 S202: 当终端接入到 WCDMA网络时, 网络根据终端上报的支持 HSPA+特 性的能力和网络侧支持的 HSPA+特性能力, 逐一匹配, 选择出网络和终端都支持的 HSPA+特性。 本实例中, 对于 R8或 R8以上版本终端, 支持 64QAM+MIMO的 HSPA+特性, 接入到既支持 64QAM, 也支持 MIMO, 但不支持 64QAM+MIMO的 WCDMA网络的 情况下,网络就可以选择出网络和终端都支持的 HSPA+特性,该特性至少包括 64QAM 和 MIMO两个。 此时需要在 64QAM和 MIMO这两个特性中选择其中一个。 步骤 S204: 网络结合当前负荷状况, 终端上报的信道质量等信息, 根据相应的算 法, 选择相应情况下增益较大的 HSPA+特性配置给终端。 本实例中,如果终端上报信道质量高于网络预定的一个门限,则配置使用 64QAM, 如果信道质量低于网络预定的一个门限, 则配置使用 MIMO, 根据信道质量衡量指标 的不同, 质量门限也可以针对不同指标, 如针对 CQI或者 Ec/No等。 步骤 S206: 当无线信号质量发生变化, 终端上报信道质量变化的信息, 或者网络 负荷等因素发生改变, 网络根据当前信息重新选择相应终端的 HSPA+特性选择, 并重 新配置给终端。 实例 2 下面结合附图 3对 WCDMA系统中既支持 64QAM, 也支持 MIMO的 R7或以上 版本终端接入到支持 64QAM+MIMO的 R8或以上版本的网络中处理过程进行描述, 该过程包括以下描述: 步骤 S302: 当终端接入到 WCDMA网络时, 网络根据终端上报的支持 HSPA+特 性的能力和网络侧支持的 HSPA+特性能力, 逐一匹配, 选择出网络和终端都支持的 HSPA+特性。 对于既支持 64QAM,也支持 MIMO,但不支持 64QAM+MIMO的 R7或以上版本 终端接入到支持 64QAM+MIMO的 R8或以上版本的网络的情况, 网络可以判断出对 该终端可以配置的 HSPA+特性可以至少包含 64QAM和 MIMO二者中任何一个。 步骤 S304: 网络结合负荷状况, 终端上报的信道质量等信息, 根据相应的算法, 选择相应情况下增益较大的 HSPA+特性配置给终端。 例如, 如果 UE上报信道质量高于网络预定的一个门限, 则配置使用 64QAM, 如 果其上报的信道质量低于网络预定的一个门限, 则配置使用 MIMO, 根据信道质量衡 量指标的不同, 质量门限也可以针对不同指标, 如针对 CQI或者 Ec/No等。 步骤 S306: 当无线信号质量发生变化, 终端上报信道质量变化的信息, 或者网络 负荷等因素发生改变, 网络根据当前信息重新选择相应终端的 HSPA+特性选择, 并重 新配置给终端。 实例 3 下面结合附图 4对 WCDMA系统中 R9或以上版本支持 DC-HSDPA+MIMO特性 的终端接入到既支持 MIMO, 也支持 DC-HSDPA特性的 R8及以上版本的网络中处理 过程进行描述, 该过程包括以下步骤: 步骤 S402: 当终端接入到 WCDMA网络时, 网络根据终端上报的支持 HSPA+特 性的能力和网络侧支持的 HSPA+特性能力, 逐一匹配, 选择出网络和终端都支持的 HSPA+特性。 对于 R9或以上版本支持 DC-HSDPA+MIMO特性的终端接入到既支持 MIMO,也 支持 DC-HSDPA特性,但不支持 DC-HSDPA+MIMO的 R8或以上版本的网络的情况, 网络可以判断出对该终端可以配置的 HSPA+特性可以至少包含 DC-HSDPA和 MIMO 二者中任何一个; 步骤 S404: 网络结合负荷状况, UE上报的信道质量等信息, 根据相应的算法, 选择相应场景下增益较大的 HSPA+特性配置给终端。 例如, 如果 UE上报信道质量高于网络预定的一个门限, 则配置使用 MIMO, 如 果信道质量低于网络预定的一个门限, 则配置使用 DC-HSDPA; 网络负荷高于网络预 定的一个门限, 则配置使用 MIMO, 网络质量低于网络预设的一个门限, 则配置使用 DC-HSDPA, 根据信道质量衡量指标的不同, 质量门限也可以针对不同指标, 如针对 CQI或者 Ec/No等。 步骤 S406: 当无线信号质量发生变化, 终端上报信道质量变化的信息, 或者网络 负荷等因素发生改变, 网络根据当前信息重新选择相应终端的 HSPA+特性选择, 并重 新配置给终端。 实例 4 下面结合附图 5对 WCDMA系统中既支持既 DC-HSDPA, 也支持 MIMO的 R8 或以上版本终端接入到支持 DC-HSDPA+MIMO特性的 R9或以上版本网络中处理过程 进行描述, 该过程包括以下步骤: 步骤 S502: 当终端接入到 WCDMA网络时, 网络根据终端上报的支持 HSPA+特 性的能力和网络侧支持的 HSPA+特性能力, 逐一匹配, 选择出网络和终端都支持的 HSPA+特性。 对于既支持 DC-HSDPA, 也支持 MIMO, 但不支持 DC-HSDPA+MIMO的 R8或 以上版本终端接入到支持 DC-HSDPA+MIMO特性的 R9或以上版本网络的情况,网络 可以判断出对该终端可以配置的 HSPA+特性可以至少包含 DC-HSDPA和 MIMO二者 中任何一个。 步骤 S504: 网络结合负荷状况, UE上报的信道质量等信息, 根据相应的算法, 选择相应情况下增益较大的 HSPA+特性配置给终端。 例如, 如果 UE上报信道质量高于网络预定的一个门限, 则配置使用 MIMO, 如 果信道质量低于网络预定的一个门限, 则配置使用 DC-HSDPA;

当信道质量较差时, 由于使 用 DC HSDPA产生的吞吐量增益高于使用 MIMO特性产生的增益, 因此这种情况下 可以选择使用 DC HSDPA, 对于其他 HSPA+特性也可以根据具体受影响的因素, 采用 上述类似方式进行选择。 本实施例中的性能增益可以是体现在网络吞吐量或用户数据速率等指标的参数。 在进行具体配置时, 配置模块 96可以通过 RRC配置消息将选择的 HSPA+特性通 知给终端。 这样, 后续终端和网络侧设备将使用该 HSPA+特性进行数据的传输。 此外, 考虑到网络状态会时常发生变化, 例如: 当终端由于移动等原因, 导致其 所处位置信道质量发生变化, 或者网络负荷等因素发生变化;
