Description

小区下行准入方法及网络侧设备
技术领域
本发明涉及无线通信技术领域, 特别涉及小区下行准入方法及网络 侧设备。 发明背景
随着移动通信技术的日益进步, 移动用户数量急剧增长, 这给移动 通信系统带来了新的压力, 特别是对移动通信系统中的接入控制技术提 出了更高的要求。接入控制技术是移动通信系统中实现对用户设备( User Equipment, 筒称 "UE" )接入无线信道的一种控制方法。
下面对移动通信系统中的接入控制技术作一下筒要说明。 在移动通 信系统中, UE在每个相邻小区中移动时, 当进入某一个小区完成位置 登记注册后, UE就驻留在该小区中, 并进入空闲状态, 该小区也就称 为 UE的当前小区。 在空闲状态下, 如果 UE执行小区位置更新过程, 或者需要对小区来的寻呼进行应答, 或者需要和其它用户建立呼叫, 包 括业务请求、 发送短消息请求等, 则 UE会向当前小区基站发送接入请 求。 需要说明的是, 随机接入过程由该 UE发起。 UE在随机接入信道上 向小区基站发送接入请求, 进行接入试探。 当网络侧接收到 UE的接入 请求后, 便在一个公共信道上给 UE回信道分配消息, 然后 UE和基站 在分配的特定信道上进行数据交互。 还需要说明的是, UE发起的随机 接入过程是根据当前小区基站的接入资源, 并按照特定的算法来完成 的。 UE在可用的接入资源中选择接入时隙, 这种选择是随机的, 然后 基站在收到 UE 的接入试探后, 小区基站就发送一个接入指示消息给 UE, 表明当前 UE是否接入成功。 如果随机接入不成功, 那么 UE则无 法和当前小区进行数据交互 , 不能完成通话或者数据传输的功能。
由于在无线通信系统中, 无线资源是非常宝贵的, 因此, 需要对 UE 发起的接入请求进行准入控制, 以实现在为更多的用户服务的同时, 保 证已有用户的服务质量。
对请求接入的 UE的准入控制通常分为上行准入控制和下行准入控 制。 并且对 UE 的下行准入控制通常是基于小区的下行总发射功率 ( Transmit Carrier Power, 筒称 " TCP" )来进行的, 即如果小区的下行 总发射功率超过了一定的门限, 则拒绝新 UE的接入请求, 否则准入。
下面筒单介绍一下现有技术中对新 UE的下行准入控制。
假设小区当前的下行总发射功率为 P'。w , 通过某种方式预测出准入 新 UE以后下行发射功率会增加 ΔΡ , 则如果: p ttal + AP < Thd !^ , 则准 入新 UE的接入请求; 否则拒绝新 UE的接入请求。 其中, ^^为小区的 最大发射功率, Thd为设置的门限因子, 在 0到 1之间。
在实现本发明过程中, 发明人发现现有技术中至少存在以下问题: 对于高速下行分组接入(High Speed Downlink Packet Access , 筒称 "HSDPA" )小区, UE的接入受到了一定程度的限制。 这是因为, 该方 案是从小区下行总发射功率的角度进行考虑的, 没有考虑到 HSDPA小 区中已有用户的满意情况, 从而有可能造成系统中 HSDPA小区已有的 用户都得到了超满意服务, 但是却拒绝了新用户的 UE的接入请求。 发明内容
本发明实施方式提供了一种小区下行准入方法及网络侧设备, 使得 HSDPA小区的下行准入能得到更有效的控制。
本发明实施方式提供的一种小区下行准入方法, 包括:
接收高速下行分组接入 HSDPA接入请求; 在小区的当前所有 HSDPA信道上的 HSDPA业务的获得的速率之 和, 与所述 HSDPA业务的保证速率之和满足预定条件时, 则准许所述 HSDPA接入请求。
本发明实施方式提供的一种网络侧设备, 包括:
接收模块, 用于接收 HSDPA接入请求;
判断模块,用于判断小区的当前所有 HSDPA信道上的 HSDPA业务 的获得的速率之和, 与所述 HSDPA业务的保证速率之和是否满足预定 条件; 和
准入决策模块, 用于接收所述判断模块的判断结果, 在所述获得的 速率之和与所述保证速率之和满足预定条件时, 准许所述 HSDPA接入 请求。
应用本发明实施方式时, 由于在 HSDPA小区中, 当前所有 HSDPA 信道上的 HSDPA业务获得的速率之和,即是接收该 HSDPA业务的所有 用户的当前速率之和;当前所有 HSDPA信道上的该 HSDPA业务的保证 速率之和, 即是接收该 HSDPA业务的所有用户的保证速率之和。 判断 获得的速率之和与保证速率之和之间的关系, 也就是判断已有用户的当 前速率之和与已有用户的保证速率之和之间的关系, 从而体现出已有的 HSDPA用户的满意度, 因此,通过当前速率之和与保证速率之和之间的 关系,确定已有 HSDPA用户的满意度,在已有的 HSDPA用户满意的情 况下, 直接准入新的 UE。 避免了当系统中已有的用户都得到了超满意 服务时, 拒绝新 UE的接入请求的情况, 使得 HSDPA小区的下行准入 能得到更有效的控制, 从而提高了 UE的接入成功率, 进而提高了整个 网络的性能。 附图简要说明

Figure imgf000008_0001
其中, 为准入该 UE后增加的下行发射功率, P 为小区的下行 最大发射功率, ™«。"- 。为为非 HSDPA业务设置的门限。 如果不满足 该公式, 则说明在准入该 UE后, 小区当前所有非 HSDPA信道的总发 射功率将不满足要求, 因此, 直接进入步骤 140, 拒绝该 UE的接入请 求; 如果满足该公式, 则说明在准入该 UE后, 所有非 HSDPA信道的 总发射功率仍将满足要求, 进入步骤 120 在步骤 120中, 网络侧判断小区的当前下行总发射功率是否满足要 求。 具体地说, 网络侧判断小区的当前下行总发射功率^ 是否满足公 式:
U AP < Thd * P— 、 其中, 为准入该 UE后增加的下行发射功率, ^ 为小区的下行 最大发射功率, Thd为设置的门限因子, 在 0到 1之间。 如果满足该公 式, 则说明在准入该 UE后, 小区的当前下行总发射功率仍将满足要求, 因此, 进入步骤 130, 准许该 UE的接入请求; 如果不满足该公式, 则 说明在准入该 UE后, 小区的当前下行总发射功率将不满足要求, 因此, 进入步骤 140, 拒绝该 UE的接入请求, 以免影响到已有用户的服务质 量。
由于 HSDPA小区既有 HSDPA信道,也有 DCH信道, 因此对于 UE 的非 HSDPA接入请求,网络侧在判断小区的当前下行总发射功率 是 否满足条件前,先判断小区当前所有非 HSDPA信道的总发射功率 是否满足一定条件, 使得在功率资源准入的过程中, 不仅考虑到系统的 下行总发射功率,同时考虑到非 HSDPA业务的总发射功率,使得 HSDPA 小区的下行准入能得到更有效的控制, 从而提高整个网络的性能。 图 2为本发明实施方式 HSDPA小区中 HSDPA接入请求的准入方法 流程图。
在步骤 210中, 网络侧在收到来自 UE的 HSDPA接入请求时, 判 断已有的 HSDPA业务的服务质量是否得到满足。 具体地说, 当网络侧收到 HSDPA实时业务接入请求, 如流业务接 入请求或 HSDPA尽力而为 ( Best Effort, 筒称" BE" ) 业务接入请求时, 判断当前所有 HSDPA信道上的所有 HSDPA业务获得的速率之和与所有 HSDPA业务的保证速率之和是否满足公式:
∑yi > rMM *∑ i ( 3 ) 其中,∑V '为当前所有 HSDPA信道上的 HSDPA业务获得的速率之 和, ∑G '为 HSDPA 业务的保证速率之和, ™速賴子为保证速率的比例 因子。 在本实施方式中, HSDPA业务为所有 HSDPA业务。 如果满足该 公式, 则说明当前 HSDPA用户已经得到了满意的服务, 因此, 直接进 入步骤 240, 准许该 UE的接入请求。 由于在 HSDPA小区中, 可以通过已有用户的当前速率之和与已有 用户的保证速率之和之间的关系,体现出已有的 HSDPA用户的满意度, 因此, 可以在已有的 HSDPA用户满意的情况下, 直接准入新的 UE。 避 免了当系统中已有的用户都得到了超满意服务时, 却还拒绝了新 UE的 接入请求的情况, 使得 HSDPA小区的下行准入能得到更有效的控制, 从而提高了 UE的接入成功率, 进而提高了整个网络的性能。 如果当前所有 HSDPA信道上的所有 HSDPA业务获得的速率之和与 所有 HSDPA业务的保证速率之和不满足公式(3 ), 则进入步骤 220。 在步骤 220 中, 网络侧判断小区当前所有 HSDPA 信道的所有
HSDPA业务总发射功率∑ 是否满足公式: Pi < Thdhsdpa * P ( 4 ) 其中, Pi为满足一个 HSDPA信道上的 HSDPA业务的保证速率所需 要的功率, ΛΡ为准入该 UE后增加的下行发射功率, Ρ - 。为小区的
HSDPA信道的最大可用发射功率,™ 。为为 HSDPA业务设置的门限。 在本实施方式中, HSDPA业务为所有 HSDPA业务。如果不满足该公式, 则说明在准入该 UE后, 小区当前所有 HSDPA信道的总发射功率将不 满足要求, 因此, 直接进入步骤 250, 拒绝该 UE的接入请求; 如果满 足该公式, 则说明在准入该 UE后, 所有 HSDPA信道的总发射功率仍 将满足要求, 进入步骤 230。 在步骤 230中, 网络侧判断小区的当前下行总发射功率是否满足要 求。 具体地说, 网络侧判断小区的当前下行总发射功率^ 是否满足公 式 (2 ), 如果满足该公式, 则说明在准入该 UE后, 小区的当前下行总 发射功率仍将满足要求, 因此, 进入步骤 240, 准许该 UE的接入请求; 如果不满足该公式, 则说明在准入该 UE后, 小区的当前下行总发射功 率将不满足要求, 因此, 进入步骤 250, 拒绝该 UE的接入请求, 以免 影响到已有用户的服务质量。
在应用本实施方式时, 不限制执行步骤 220和步骤 230的顺序, 即 在步骤 220中, 可以由网络侧判断小区的当前下行总发射功率是否满足 要求; 在步骤 230中, 可以由网络侧判断小区当前所有 HSDPA信道的 总发射功率∑ 是否满足要求。
不难发现,当所有 HSDPA信道上的所有 HSDPA业务获得的速率之 和与所有 HSDPA业务的保证速率之和不满足预定条件, 即公式( 3 )时, 可以通过结合小区下行的总发射功率, 对是否准入该 UE进行判断, 进 一步完善了小区下行准入方法, 使得 HSDPA小区的下行准入能得到更 有效的控制, 从而提高整个网络的性能。 进一步地, 网络侧在判断小区的当前下行总发射功率 Ρ^是否满足 条件前, 还可以先判断小区当前所有 HSDPA信道的总发射功率是否满 足一定条件, 使得在功率资源准入的过程中, 不仅考虑到系统的下行总 发射功率, 同时考虑到 HSDPA业务的总发射功率,使得 HSDPA小区的 下行准入能得到更有效的控制。
需要说明的是, 本实施方式中的当前所有 HSDPA信道上的所有 HSDPA业务获得的速率之和与所有 HSDPA业务的保证速率之和, 所要 满足的公式也可以是:
∑V; > 7M速賴子 ( 5 ) 其中,∑V '为当前所有 HSDPA信道上的所有 HSDPA业务获得的速 率之和, ∑G!为所有 HSDPA 业务的保证速率之和, ™«糊子为保证速 率的比例因子, Δ可为当前所有 HSDPA信道上的所有 HSDPA业务获得 的速率之和至少需要满足的门限值, 以避免在保证速率为 0 , 即 Γ 速賴子 *∑G,' = o, ∑ 一定大于速率因子 *∑(^时, 对 UE的 HSDPA 接入请求无条件准入的情况。由于该公式同样能够体现出已有的 HSDPA 用户的满意度, 因此, 可以作为新 HSDPA用户准入的条件。 通过获得 速率之和与保证速率之和间的比较, 避免了当系统中已有的用户都得到 了超满意服务时, 却还拒绝了新 UE 的接入请求的情况, 使得 HSDPA 小区的下行准入能得到更有效的控制, 从而提高了 UE的接入成功率, 进而提高了整个网络的性能。 本发明的第二实施方式涉及小区下行准入方法, 本实施方式与第一 实施方式大致相同, 其区别在于, 在第一实施方式中, 对于 HSDPA接 入请求,并不区分该接入请求是 HSDPA实时业务接入请求,还是 HSDPA BE业务接入请求, 而在本实施方式中, 进一步将 HSDPA接入请求区分 为 HSDPA实时业务接入请求和 HSDPA BE业务接入请求,其中, HSDPA 实时业务接入请求可以包括 HSDPA流业务接入请求, 相应的准入流程 分别如图 3和图 4所示。 图 3为本发明实施方式 HSDPA小区中 HSDPA实时业务接入请求的 准入方法流程图。 在步骤 310中, 网络侧在收到来自 UE的 HSDPA实 时业务接入请求时, 判断已有的 HSDPA实时业务的服务质量是否得到 满足。 具体地说, 当网络侧收到 UE的 HSDPA实时业务接入请求时, 判 断当前所有 HSDPA 信道上的 HSDPA 实时业务获得的速率之和与 HSDPA实时业务的保证速率之和是否满足公式(3 ), 其中公式(3 ) 中 的 HSDPA 业务为 HSDPA 实时业务。 如果满足该公式, 则说明当前 HSDPA实时业务用户已经得到了满意的服务,因此,直接进入步骤 340, 准许该 UE的接入请求。 述。
图 4为本发明实施方式 HSDPA小区中 HSDPA BE业务接入请求的 准入方法流程图。 在步骤 410中, 网络侧在收到来自 UE的 HSDPA BE 业务接入请求时,判断已有的 HSDPA BE业务的服务质量是否得到满足。
具体地说, 当网络侧收到 UE的 HSDPA BE业务接入请求时, 判断 当前所有 HSDPA信道上的 HSDPA BE业务获得的速率之和与 HSDPA BE业务的保证速率之和是否满足公式( 3 ) ,其中在公式( 3 )中的 HSDPA 业务为 HSDPA BE业务。如果满足该公式, 则说明当前 HSDPA BE业务 用户已经得到了满意的服务, 因此, 直接进入步骤 440, 准许该 UE的 接入请求。
述。
由于不同类型的 HSDPA业务具有不同的服务质量的要求, 因此, 通过对 HSDPA业务进行区分,可以为不同类型的 HSDPA业务设置不同 的用户满意度。 比如说, 为 HSDPA实时业务保证速率的比例因子设置 的值设置高于为 HSDPA BE业务保证速率的比例因子设置的值,使得在 衡量已有的 HSDPA实时业务用户的满意度时, 具有更高的要求, 保证 了 HSDPA实时业务的用户, 可以得到更高的满意度。
本实施方式中对于非 HSDPA接入请求的准入方法与第一实施方式 完全相同, 在此不再赘述。 值得一提的是, 虽然在本实施方式中,在判断小区当前所有 HSDPA 信道的总发射功率∑ 是否满足公式(4 )时,没有对不同类型的 HSDPA 业务进行区分, 即 是满足一个 HSDPA信道上的 HSDPA业务的保证速 率所需要的功率, 为 HSDPA业务设置的门限。 但在实际应用 中,也可以将当前所有 HSDPA信道的总发射功率区分为所有 HSDPA信 道的 HSDPA实时业务的总发射功率, 或者所有 HSDPA信道的 HSDPA BE业务的总发射功率。 比如说,对于 HSDPA实时业务,判断小区当前所有 HSDPA信道的
HSDPA实时业务的总发射功率∑ 是否满足公式(4 ), 其中公式(4 ) 中的 HSDPA业务为 HSDPA实时业务。如果满足该公式, 则再进行小区 下行总功率的判断。
对于 HSDPA BE业务,判断小区当前所有 HSDPA信道的 HSDPA BE 业务的总发射功率∑ 是否满足公式(4 ), 其中公式(4 ) 中的 HSDPA 业务为 HSDPA BE业务。 在满足要求时, 进一步判断当前小区当前所有
HSDPA信道的 HSDPA实时业务的总发射功率∑ 是否满足公式( 4 ), 其中公式(4 )中的 HSDPA业务为 HSDPA实时业务。 在均满足要求时, 则再进行小区下行总功率的判断。 进一步保证了具有较高服务质量要求 的 HSDPA业务的用户, 可以得到更高的满意度。 本发明的第三实施方式涉及小区下行准入系统, 如图 5所示, 包含 UE 和网络侧设备。 其中, 网络侧设备包含: 接收模块, 用于接收 UE 的接入请求; 判断模块, 用于在该接收模块收到 UE的 HSDPA接入请 求时,判断当前所有 HSDPA信道上的 HSDPA业务获得的速率之和, 与 当前所有 HSDPA信道上的该 HSDPA业务的保证速率之和是否满足预定 条件; 和准入决策模块, 用于接收所述判断模块的判断结果, 在该判断 模块判定满足预定条件时, 直接准许该 UE的接入请求。
该预定条件是公式( 3 )或者公式( 5 )。 由于本实施方式通过已有用户的当前速率之和与已有用户的保证 速率之和之间的关系, 体现出已有的 HSDPA用户的满意度, 将当前速 率之和与保证速率之和之间的关系作为新 HSDPA用户准入的充分条件, 避免了当系统中已有的用户都得到了超满意服务时, 却还拒绝了新 UE 的接入请求的情况,使得 HSDPA小区的下行准入能得到更有效的控制, 从而提高了 UE的接入成功率, 进而提高了整个网络的性能。
如果判断模块判定当前所有 HSDPA信道上的 HSDPA业务获得的速 率之和,与当前所有 HSDPA信道上的该 HSDPA业务的保证速率之和不 满足预定条件, 则进一步判断小区当前所有 HSDPA信道的总发射功率
∑^是否满足公式( 4 )。 准入决策模块在该判断模块判定该∑ 不满足 公式( 4 ) 时, 直接拒绝该 UE的接入请求。 如果判断模块判定该∑ 满足公式( 4 ), 则进一步判断小区的当前 下行总发射功率 P 是否满足公式( 2 ), 准入决策模块在该 P I满足公式
( 2 ) 时, 准许该 UE 的接入请求, 在该 pf不满足公式(2 ) 时, 拒绝 该 UE的接入请求。
当判断模块判定当前所有 HSDPA信道上的 HSDPA业务获得的速率 之和,与当前所有 HSDPA信道上的该 HSDPA业务的保证速率之和不满 足预定条件时, 判断模块还可以判断所述小区的当前下行总发射功率 。'是否满足公式(2 ); 准入决策模块在所述当前下行总发射功率满足 公式(2 ) 时, 准许该接入请求, 否则, 拒绝该接入请求。
另外, 该判断模块还用于在接收模块收到 UE的非 HSDPA接入请 求时, 判断小区当前所有非 HSDPA信道的总发射功率 。"-¾ 是否满足 公式(1 ), 准入决策模块在该判断模块判定该 P«。《- 。不满足公式 (1 ) 时, 直接拒绝该 UE的接入请求。 如果该判断模块判定该 。"- ¾ 满足公式(1 ), 则进一步判断小区的 当前下行总发射功率7^是否满足公式( 2 ) , 准入决策模块在该 满足 公式(2 ) 时, 准许该 UE 的接入请求, 在该^。'不满足公式(2 ) 时, 拒绝该 UE的接入请求。
在本实施方式中,当 HSDPA接入请求为 HSDPA实时业务接入请求 时, HSDPA业务可以为 HSDPA 实时业务或所有的 HSDPA业务。 当 HSDPA接入请求为 HSDPA BE接入请求时, HSDPA业务可以为 HSDPA BE业务或所有的 HSDPA业务。
图 6为本发明实施方式 HSDPA小区中 HSDPA接入请求的准入方法 流程图。
在步骤 610中, 网络侧在收到来自 UE的 HSDPA接入请求时, 判 断已有的 HSDPA业务的服务质量是否得到满足。
具体地说, 当网络侧收到 HSDPA实时业务接入请求或 HSDPA BE 业务接入请求时,判断当前所有 HSDPA信道上的所有 HSDPA业务获得 的速率之和与所有 HSDPA业务的保证速率之和是否满足公式(3 )。 如 果满足该公式, 则说明当前 HSDPA用户已经得到了满意的服务, 因此, 直接进入步骤 630, 准许该 UE的接入请求。
如果当前所有 HSDPA信道上的所有 HSDPA业务获得的速率之和与 所有 HSDPA业务的保证速率之和不满足公式(3 ), 则进入步骤 620。
另外在本实施方式中, 可以进一步将 HSDPA 接入请求区分为 HSDPA实时业务接入请求和 HSDPA BE业务接入请求。
当网络侧收到 UE的 HSDPA实时业务接入请求时, 在步骤 610中 判断当前所有 HSDPA信道上的 HSDPA 实时业务获得的速率之和与 HSDPA实时业务的保证速率之和是否满足公式(3 ), 其中公式(3 ) 中 的 HSDPA 业务为 HSDPA 实时业务。 如果满足该公式, 则说明当前 HSDPA实时业务用户已经得到了满意的服务,因此,直接进入步骤 630, 准许该 UE的接入请求。 如果不满足该公式, 则进入步骤 620。 当网络侧收到 UE的 HSDPA BE业务接入请求时, 在步骤 610中判 断当前所有 HSDPA信道上的 HSDPA BE业务获得的速率之和与 HSDPA BE业务的保证速率之和是否满足公式( 3 ) ,其中在公式( 3 )中的 HSDPA 业务为 HSDPA BE业务。如果满足该公式, 则说明当前 HSDPA BE业务 用户已经得到了满意的服务, 因此, 直接进入步骤 630, 准许该 UE的 接入请求。 如果不满足该公式, 则进入步骤 620。 在步骤 620中, 网络侧判断小区的当前下行总发射功率是否满足要 求。 具体地说, 网络侧判断小区的当前下行总发射功率^ 是否满足公 式( 2 )如果满足该公式, 则说明在准入该 UE后, 小区的当前下行总发 射功率仍将满足要求, 因此, 进入步骤 630, 准许该 UE的接入请求; 如果不满足该公式, 则说明在准入该 UE后, 小区的当前下行总发射功 率将不满足要求, 因此, 进入步骤 640, 拒绝该 UE的接入请求, 以免 影响到已有用户的服务质量。
另外在应用本实施方式时, 在步骤 620中, 网络侧判断小区的当前 下行总发射功率是否满足要求可以由网络侧判断小区当前所有 HSDPA 信道的总发射功率∑ 是否满足公式(4 )代替。 综上所述, 在本发明的各实施方式中, 网络侧在收到 UE的 HSDPA 接入请求时,先判断当前所有 HSDPA信道上的 HSDPA业务获得的速率 之和与该 HSDPA业务的保证速率之和是否满足预定条件, 如果是, 则 直接准许该 UE的接入请求。 由于在 HSDPA小区中, 可以通过已有用 户的当前速率之和与已有用户的保证速率之和之间的关系, 体现出已有 的 HSDPA用户的满意度, 因此, 通过当前速率之和与保证速率之和之 间的关系,确定已有 HSDPA用户的满意度,在已有的 HSDPA用户满意 的情况下, 直接准入新的 UE。 避免了当系统中已有的用户都得到了超 满意服务时, 却还拒绝了新 UE的接入请求的情况, 使得 HSDPA小区 的下行准入能得到更有效的控制, 从而提高了 UE的接入成功率, 进而 提高了整个网络的性能。
如果当前所有 HSDPA信道上的 HSDPA业务获得的速率之和与该 HSDPA业务的保证速率之和不满足预定条件,则再结合小区下行的总发 射功率对该 UE的准入进行判断, 进一步完善了小区下行准入方法, 使 得 HSDPA小区的下行准入能得到更有效的控制, 从而提高整个网络的 性能。
对于 UE的 HSDPA接入请求, 网络侧在判断小区的当前下行总发 射功率是否满足条件前, 先判断小区当前所有 HSDPA信道的总发射功 率是否满足一定条件; 对于 UE的非 HSDPA接入请求, 网络侧在判断 小区的当前下行总发射功率是否满足条件前, 先判断小区当前所有非 HSDPA信道的总发射功率是否满足一定条件。使得在功率资源准入的过 程中, 全面考虑了系统的下行总发射功率, HSDPA业务的总发射功率, 以及非 HSDPA业务的总发射功率, 对 HSDPA用户和非 HSDPA用户的 准入情况进行了单独控制。 对于 HSDPA尽力而为业务的接入请求, 网络侧可以通过判断当前 所有 HSDPA信道上的 HSDPA尽力而为业务获得的速率之和与该业务的 保证速率之和是否满足预定条件,决定是否直接准许该 UE的接入请求; 对于 HSDPA 实时业务的接入请求, 网络侧可以通过判断当前所有 HSDPA信道上的 HSDPA实时业务获得的速率之和与该业务的保证速率 之和是否满足预定条件, 决定是否直接准许该 UE的接入请求。 由于不 同类型的 HSDPA业务具有不同的服务质量的要求,因此,通过对 HSDPA 业务进行区分,可以为不同类型的 HSDPA业务设置不同的用户满意度, 进一步保证了具有较高服务质量要求的 HSDPA业务的用户, 得到更高 的满意度。
虽然通过参照本发明的某些优选实施方式, 已经对本发明进行了图 示和描述, 但本领域的普通技术人员应该明白, 可以在形式上和细节上 对其作各种改变, 而不偏离本发明的精神和范围。
