本发明的较佳实施方式
本发明多制式组网的无线资源管理方法、 多制式通信网络(本发明中, 也称为多制式组网)及无线资源管理装置主要思想是, 各单制式网络之间通 过接口相互连接, 获取邻接单制式网络的无线资源信息和 /或传输资源信息; 再根据其所在单制式网络及邻接单制式网络的无线资源信息和 /或传输资源 信息进行协同管理, 从而实现多制式组网的资源的系统化管理。
如图 1所示, 本发明多制式组网的无线资源管理方法, 基于多制式组网 实现, 组成该多制式组网的各单制式网络均包括无线资源管理 (Radio Resource Management, RRM )装置, 且各单制式网络的无线资源管理装置之 间通过接口相互连接, 提供不同制式间无线资源信息的交互功能并为接入本 制式的当前业务选择合适制式, 以达到整个系统资源的最优配置。
该方法包括:
步骤 101 : 单制式网络的无线资源管理装置获取邻接单制式网络的无线 资源信息和 /或传输资源信息;
步骤 102: 所述单制式网络的无线资源管理装置根据其所在单制式网络 及邻接单制式网络的无线资源信息和 /或传输资源信息进行协同管理。
即, 无线资源管理装置负责把本制式的无线资源信息和 /或传输资源信息 传送到其它制式, 且从其它制式获取相应的无线资源信息和 /或传输资源信 息; 当本制式无线系统有接入请求时, 综合本制式和其它制式的无线资源信 息和 /或传输资源信息, 在多种制式并存的系统中决策最优的目标小区。
多制式通信网络系统中各单制式通信网络的无线资源管理装置之间通过 分布式的架构相连; 各单制式通信网络无线资源管理装置可以是一个物理实 体的或逻辑单元。
不同单制式通信网络之间通过 Co-RRM ( Cooperative Radio Resource
Management, 协同无线资源管理)接口 (也即多模控制器内部不同制式间的 接口)或 Iur-g接口相连, 相同制式之间通过 Iur接口 /Iu口随路相连。
如图 2 所示, 各单制式通信网络的无线资源管理装置通过 Co-RRM(Cooperative Radio Resource Management)、 Iur-g、 Iur接口相连; 这些 无线资源管理装置可以是 TD-SCDMA、 WCDMA通信网络中的无线网络控制 器(Radio Network Controller, RNC ) 、 GSM通信通信网络中的基站控制器 ( Base Station Controller, BSC ) 、 CDMA移动通信网络中的基站控制器 ( CDMA Base Station Controller, CBSC )等。 其中, 通过 Co-RRM接口相连 的两个无线资源管理装置属于同一多模控制器网元内, 图中用虚线框标示。
不同制式通信网络 RRM装置之间通过相应的接口交互无线资源、 传输 资源信息, 其中 Iur-g或 Iur接口之间仅可以交互无线负荷信息, Co-RRM接 口除了可以交互无线负荷信息之外, 还可以交互小区属性信息、 传输资源信 息等。
各无线资源管理装置预先配置协同管理策略并根据所述协同管理策略进 行协同管理, 所述协同管理策略包括但不限于以下策略:
负载平衡策略,选择负载最轻的单制式网络作为接入或切换的目标网络; 即, 综合考虑各邻接单制式网络的负载状况, 把业务接入或重定向到负荷最
轻的系统中, 从而实现无线资源利用率的最大化, 最大程度地利用多制式通 信网络的无线资源, 进而提高多制式覆盖区域的中继容量; 实现多制式网络 中各单制式网络之间的切换, 避免只考虑单一制式通信网络的因素导致的频 繁切换, 最大程度地提高用户体验。
或, 负载门限策略, 当前单制式网络负载超过预设门限时, 将特定业务 切往特定异制式网络;
或, 目标小区选择策略, 将负载最轻或信号质量最好的小区作为接入或 切换的目标小区, 如根据各邻接制式网络的信号质量、 无线负荷、 传输负荷, 确定异制式系统信号质量最优的目标小区。
为了避免不同制式间相关策略的冲突预先配置各制式系统优先承载的业 务, 具体根据运营商的需求定制, 如 CS业务优先 2G系统, PS业务优先 3G 系统; 对某业务进行协同管理前, 所述无线资源管理装置先根据该业务的业 务请求参数确定业务类型; 无线资源管理装置根据当前业务类型及各制式优 先承载的业务进行协同管理。
具体实现时, 协同管理策略可针对不同的业务制定不同的策略, 各策略 可视情形单独或组合使用。
所述无线资源管理装置周期方式或事件方式获取邻接单制式网络的信 息。
所述无线资源信息包括小区的系统信息、 无线资源负荷信息或小区属性 信息。
所述协同管理包括:
在业务接入时或业务保持过程中, 根据所在单制式网络、 邻接单制式网 络的信息为新接入业务或待切换业务选择目标单制式网络及目标小区, 见实 施例一
或, 收到终端上报的系统间测量报告时, 用于根据所在单制式网络、 邻 接单制式网络的信息为所述终端选择切换的目标单制式网络及目标小区, 见 实施例二。
若所述测量报告为覆盖类触发,则选择信号质量最高的小区为目标小区,
若所述测量才艮告为负荷类触发, 则选择负载最轻的小区为目标小区。
所述无线资源管理装置选择目标小区前, 先剔除预接纳失败的小区, 并 根据信号质量或负荷排序生成目标小区列表, 再从中选择所述目标小区。
不同制式 RRM装置间信息交互如图 3所示, 其中图 3 ( a )为不同制式 间信息交互的示意图。 当一种制式需要另一种制式的负荷信息时, 向对端发 起负荷信息请求, 对端收到请求消息后, 收集本制式的负荷信息并回应答消 息; 信息的同步可以是事件方式也可以是周期方式。 负荷信息根据不同的连 接接口, 可以定义成不同的方式: 对多模控制器内 Co-RRM接口, 负荷信息 可以包括两部分: 协议中定义的 Iur-g基本信息和自定义的增强信息部分; 对 WCDMA, 增强信息部分可以包括: RTWP、 TCP 和 CE 资源等信息; 对 TD-SCDMA, 增强信息部分可以包括: 小区的 CS、 PS容量, 剩余可接入的 用户数; 对 GSM, 增强信息部分可以包括: 小区 CS、 PS剩余容量, 剩余可 接入的用户数等。
图 3 ( b )为不同制式小区属性交互的示意图, 信息同步的方式可以是事 件方式也可以是周期方式; 对 WCDMA或 TD-SCDMA, 小区属性主要包括: 小区支持的频段属性和小区当前的状态属性; 对 GSM, 小区属性主要包括: 小区的业务支持属性、 DTM业务支持属性和小区当前的状态属性; 其中小区 当前的状态属性分为: 小区当前可用和小区当前不可用两种属性。
图 3 ( c )是系统消息的变更通知, 可以事件通知也可以周期性通知。
以下结合附图, 对本发明协同管理的流程进行说明。
实施例一
在业务接入过程中, 也即当无线网络控制器(RNC )收到无线资源控制 连接请求( RRC CONNECTION REQUEST )和无线接入承载分配请求( RAB ASSIGNMENT REQUEST ) 时, 根据当前服务小区的负荷及邻接制式所有邻 区的负荷状况, 结合各制式网络预置的优先承载业务类型为接入的呼叫选择 一个负荷最轻的小区, 达到各制式小区间的负荷均衡。 在无线接入承载分配
请求( RAB ASSIGNMENT REQUEST ) 阶段, 对 CS业务用实时负荷衡量各 制式小区的负荷, 对 PS业务用非实时负荷衡量各制式小区的负荷。
如图 4所示, 无线资源管理装置 1和它相连的其他单制式网络的无线资 源管理装置 2、 3的进行交互实现负载协同控制的流程包括如下步骤:
步骤 400: 无线资源管理装置 1 所在的单制式网络的无线网络控制器
( RNC ) 收到终端发起的无线资源控制连接请求 (RRC CONNECTION REQUEST )消息或核心网发起的无线接入承载分配请求( RAB ASSIGNMENT REQUEST ) 消息;
步骤 401 : 无线资源管理单元 1向无线资源管理单元 2发起小区信息请 求, 小区信息具体包括小区的总负荷、 实时负荷、 非实时负荷、 传输资源信 息和小区属性信息;
步骤 402: 无线资源管理装置 1向无线资源管理装置 3发起小区信息请 求, 小区信息具体包括小区的总负荷、 实时负荷、 非实时负荷、 传输资源信 息和小区属性信息;

步骤 405: 无线资源管理装置 1跟据各制式的邻区的无线负荷、 传输负 荷及小区属性信息, 首先进行预接纳即预删选预接纳失败的小区, 其次根据 负荷从低到高进行排序生成目标小区列表; 对于有的接口不支持传输资源信 息的获取如 Iur-g接口, 则不进行传输资源的预接纳判决; 不同制式间的负荷 可以通过统一的标准进行折算, 如对 CS业务统一折算成可接入的 CS12.2K 的用户数, 对 PS业务统一折算成可接入一定保障速率(如 32K ) 的业务数; 步骤 406: 无线资源管理装置 1向终端发起目标小区的重定位命令。 实施例二
跨制式的系统间切换, 主要由两种原因触发: 一^^于覆盖的原因触发; 二是基于负荷的原因触发。 不管是哪种触发原因, 都要从其它制式获取测量 报告中上报小区的无线负荷、 传输负荷及小区属性信息; 首先进行预接纳即 预删除过程, 其次进行基于负荷或信号质量的排序, 从而选择目标小区。
如图 5所示, 无线资源管理装置 1和它相连的无线资源管理装置 2、 3进 行交互切换协同控制的流程包括如下步骤:
步骤 500: 无线资源管理装置 1 收到终端上 的系统间测量 ^艮告, 用例 开始;
步骤 501 : 无线资源管理装置 1向无线资源管理装置 2的发起小区信息 请求, 小区信息具体包括小区的总负荷、 实时负荷、 非实时负荷、 传输资源 信息和小区属性信息;
步骤 502: 无线资源管理装置 1向无线资源管理装置 3发起小区信息请 求, 小区信息具体包括小区的总负荷、 实时负荷、 非实时负荷、 传输资源信 息和小区属性信息;
步骤 503: 无线资源管理装置 2向无线资源管理装置 1回小区应答消息, 应答消息中包含请求的小区的无线负荷、 传输负荷和小区属性信息;
步骤 504: 无线资源管理装置 3向无线资源管理装置 1回小区应答消息, 应答消息中包含请求的小区的无线负荷、 传输负荷和和小区属性信息;
步骤 505: 无线资源管理装置 1对测量报告中上报小区组成的候选小区 列表进行无线资源、 传输资源和小区属性预接纳, 剔除预接纳失败的小区; 对覆盖类触发的测量报告, 按信号质量从高到低进行排序; 对负荷类触发的 测量报告按负荷从低到高进行排序;
步骤 506: 对以上步骤生成的候选小区列表, 按优先级从高到低依次发 起系统间切换流程。
