技术领域
本发明涉及通信领域, 尤其涉及通信领域中用于控制访问核心网的方 法、 网络设备和用户设备。 背景技术
在目前的通信系统中, 为了避免核心网出现拥堵或发生故障, 网络运 营管理( Operation And Management, 筒称为' ΌΑΜ" )中心节点获得核心网 的负载信息后, 生成用于控制用户设备访问核心网或核心网节点的访问控 制信息,并通过 ΟΑΜ与服务无线接入网节点的接口, 配置给服务无线接入 网节点。服务无线接入网节点获得来自 ΟΑΜ的访问控制信息后,可以通过 无线接入网 ( Radio Access Network, 筒称为" RAN" )侧的小区系统广播消 息, 针对不同访问级别的用户设备(User Equipment, 筒称为 "UE" )发送是 否允许访问核心网的访问控制参数。 该访问控制参数可以是核心网域访问 控制( Domain Specific Access Control , 筒称为" DSAC" )信息, 也可以是寻 呼允许访问控制 (Paging Permission Access Control, 筒称为 "PPAC" )信息。
通过 DSAC信息控制用户设备是否访问核心网的原理为: UE接收和存 储从小区系统广播消息中得到的上述访问控制信息后, 在发起对特定核心 网节点的新建业务时, 判断客户识别模块(Subscriber Identity Module , 筒 称为" SIM" )卡中存储的访问控制 (Access Control, 筒称为 "AC" )值, 并 确定与该 AC 值对应的 DSAC 信息; 如果该 DSAC 信息的取值是受限 ( Barred ), 则 UE不能进行访问核心网的尝试; 如果该 DSAC信息的取值 为不受限( Not Barred ), 可以 UE可以进行访问核心网的尝试, 由此可以实 现对核心网节点的负载控制。
类似地, 通过 PPAC信息控制用户设备是否访问核心网的原理为: UE 进入小区后, 从小区的广播信道上接收 PPAC信息; UE收到寻呼消息后, 当 UE发起对该寻呼消息的响应消息, 或者发起位置更新( Location Update 或 Registration Update )消息, 或者向网络发起注册流程时, UE会先判断从 小区广播信道上接收的 PPAC消息的取值;如果 PPAC消息的取值为不受限, 则 UE可以发起上述的寻呼响应消息或者位置更新消息或者注册消息;如果 该 PPAC信息的取值为受限,则 UE需要进一步判断网络希望针对电路交换 ( Circuit Switch, 筒称为 "CS" )域进行限制, 还是针对分组交换( Packet Switch, 筒称为 "PS" )域进行限制。
在目前的通信系统中, 上述 DSAC/PPAC是基于小区级别的访问控制信 息, 仅能够在系统广播消息中进行广播。 假设 UE在与某一个核心网域已经 建立了连接, 例如已经建立 CS域连接, 如果 UE在 CS通话过程中由于移动性 等原因发生了小区变更或者切换, 切换后的新服务无线网络控制器(Radio Network Controller , 筒称为 "RNC" )所连接的 PS域核心网节点, 例如 GPRS 服务支持节点 (Serving GPRS Support Node, 筒称为 "SGSN", 其中通用分 组无线服务( General Packet Radio Service ) 筒称为" GPRS" ) 的负载信息发 生变化, 或者由于 SGSN发生变化, 导致新的服务小区中的访问控制信息发 生改变。 然而, 对于处于非小区专用信道(Cell Dedicated Channel, 筒称为 "CELL— DCH" )状态的 UE而言, 该 UE不能在专用信道上进行数据收发的同 时读取系统广播消息。 于是该 UE无法根据新服务小区的访问控制信息对已 存储的访问控制信息进行更新, 从而导致该 UE在发起一个新的 PS呼叫请求 之前, 不能正确地确定是否发起对核心网的访问请求。 发明内容
本发明的多个方面提供了一种用于控制访问核心网的方法、 网络设备 和用户设备, 使得用户设备能够及时更新访问控制信息, 从而用户设备能 够正确地确定是否访问核心网。
本发明的一方面, 提供了一种用于控制访问核心网的方法, 该方法包 括: 确定用于控制用户设备访问核心网的访问控制信息发生改变; 通过专 用控制信道(DCCH ) 向该用户设备发送无线资源控制 (RRC )信令, 该 RRC信令用于指示该访问控制信息发生改变, 以便于该用户设备更新该访 问控制信息。
本发明的另一方面, 提供了一种用于控制访问核心网的方法, 该方法 包括: 从小区系统广播消息中接收并存储用于控制用户设备访问核心网的 访问控制信息; 确定该访问控制信息发生改变; 清除存储的该访问控制信 息。
本发明的再一方面, 提供了一种网络设备, 该网络设备包括: 确定模 块, 用于确定用于控制用户设备访问核心网的访问控制信息发生改变; 发 送模块, 用于通过专用控制信道(DCCH )向该用户设备发送无线资源控制 ( RRC )信令, 该 RRC信令用于指示该访问控制信息发生改变, 以便于该 用户设备更新该访问控制信息。
本发明的再一方面, 提供了一种用户设备, 该用户设备包括: 接收模 块, 用于从小区系统广播消息中接收并存储用于控制用户设备访问核心网 的访问控制信息; 确定模块, 用于确定该访问控制信息发生改变; 清除模 块, 用于清除存储的该访问控制信息。

下面将结合本发明实施例中的附图, 对本发明实施例中的技术方案进行清 楚、 完整地描述, 显然, 所描述的实施例是本发明的一部分实施例, 而不 是全部实施例。 基于本发明中的实施例, 本领域普通技术人员在没有做出 创造性劳动的前提下所获得的所有其他实施例, 都应属于本发明保护的范 围。
应理解, 本发明的技术方案可以应用于各种通信系统, 例如: 全球移 动通讯 ( Global System of Mobile communication , 筒称为" GSM" ) 系统、 码 分多址( Code Division Multiple Access , 筒称为" CDMA" ) 系统、 宽带码分 多址( Wideband Code Division Multiple Access , 筒称为" WCDMA" ) 系统、 通用分组无线业务( General Packet Radio Service, 筒称为" GPRS" )、 长期演 进 ( Long Term Evolution, 筒称为 "LTE" ) 系统、 LTE频分双工( Frequency Division Duplex,筒称为" FDD" )系统、 LTE时分双工( Time Division Duplex, 筒称为 "TDD" )、 通用移动通信系统(Universal Mobile Telecommunication System,筒称为 "UMTS" ),全球互联 波访问( Worldwide Interoperability for Microwave Access , 筒称为" WiMAX" )通信系统等。
还应理解,在本发明实施例中,用户设备( User Equipment,筒称为" UE" ) 可称之为终端(Terminal ), 移动台 ( Mobile Station , 筒称为 "MS" )、 移动终 端 (Mobile Terminal ) 等, 该用户设备可以经无线接入网 (Radio Access Network, 筒称为 "RAN" )与一个或多个核心网进行通信, 例如, 用户设备 可以是移动电话(或称为"蜂窝"电话)、 具有移动终端的计算机等, 例如, 用户设备还可以是便携式、 袖珍式、 手持式、 计算机内置的或者车载的移 动装置, 它们与无线接入网交换语音和 /或数据。
在本发明实施例中, 服务无线接入网节点可以包括无线网络控制器
( RNC )、 基站( NodeB, 筒称为" NB" )、 演进型基站( Evolutional Node B , 筒称为 "eNB或 e-NodeB" )或基站控制器(Base station Controller, 筒称为 "BSC" )等; 服务无线接入网节点所连接的核心网节点可以包括 GPRS服务 支持节点 ( Serving GPRS Support Node , 筒称为" SGSN" , 其中通用分组无 线服务(General Packet Radio Service ) 筒称为 "GPRS" )、 移动性管理实体 ( Mobility Management Entity, 筒称为 "MME" )或移动交换中心 (Mobile Switching Center, 筒称为 "MSC" )等, 本发明并不限定。 但为描述方便, 下述实施例将以服务无线接入网节点包括 RNC为例进行说明。
另外, 本文中术语"系统"和"网络"在本文中常被可互换使用。本文中术 语"和 /或", 仅仅是一种描述关联对象的关联关系, 表示可以存在三种关系, 例如, A和 /或 B , 可以表示: 单独存在 A, 同时存在 A和 B, 单独存在 B 这三种情况。 另外, 本文中字符" /", 一般表示前后关联对象是一种"或"的 关系。
图 1示出了才艮据本发明实施例的用于控制访问核心网的方法 100的示 意性流程图。 图 1所示的方法 100可由用户设备的服务无线接入网节点执 行, 例如可以由 RNC执行。
S 110 , 确定用于控制用户设备访问核心网的访问控制信息发生改变。
S120, 通过专用控制信道 DCCH向该用户设备发送无线资源控制 RRC 信令, 该 RRC信令用于指示该访问控制信息发生改变, 以便于该用户设备 更新该访问控制信息。
为了使得用户设备能够及时地更新访问控制信息, 并能够正确地确定 是否访问核心网, RNC可以根据诸如负荷信息、 节点信息等多种因素, 确 定用于控制用户设备访问核心网的访问控制信息发生改变, 并可以通过 DCCH向该用户设备发送 RRC信令, 以指示用户设备访问控制信息发生改 变, 从而用户设备能够根据该 RRC信令更新访问控制信息。
因此, 本发明实施例的用于控制访问核心网的方法, 通过网络设备在 确定访问控制信息发生改变时, 经由专用控制信道通知用户设备, 使得用 户设备能够及时更新访问控制信息, 从而用户设备能够正确地确定是否访 问核心网, 由此能够有效控制核心网节点的负载, 提升系统性能。
因此, 在本发明实施例中, 服务无线接入网节点能够根据切换过程中 的一些信息, 自己确定访问控制信息发生变化, 并能够生成用于用户设备 更新的访问控制信息, 该服务无线接入网节点确定访问控制信息是否发生 变化的来源不再仅仅是网络运营管理中心节点。
应理解, 本发明实施例仅以 RNC为例进行说明, 但本发明实施例并不 限于此, 诸如基站、 演进型基站或基站控制器(BSC )的服务无线接入网节 点也可以执行上述方法 100。
还应理解, 在本发明实施例中, 处于非 CELL_DCH连接状态或空闲状 态的 UE, 不仅可以通过读取小区的系统广播消息, 获知访问控制信息发生 改变, 并进行相应地更新, 也可以通过接收 RNC发送的 RRC信令, 获知 访问控制信息发生改变。 因此, 本发明实施例不仅可以应用于处于 CELL_DCH状态的 UE , 也可以用于处于其它连接状态的 UE , 本发明实施 例仅以处于 CELL_DCH状态的 UE为例进行说明, 但本发明并不限于此。 在 S110中, 服务无线接入网节点例如可以根据用户设备的服务无线接 入网节点是否发生改变、 该用户设备的服务小区是否发生改变、 该用户设 备的服务无线接入网节点所连接的核心网节点是否发生改变、 该用户设备 的服务无线接入网节点所连接的核心网节点的访问控制信息是否发生改变 或该核心网节点的负荷情况等因素, 确定用于控制用户设备访问核心网的 访问控制信息是否发生改变。
在本发明实施例中, 可选地, 根据用户设备的服务无线接入网节点发 生改变、 该用户设备的服务小区发生改变、 该用户设备的服务无线接入网 节点所连接的核心网节点发生改变、 该用户设备的服务无线接入网节点所 连接的核心网节点的访问控制信息发生改变、 以及该用户设备的服务小区 的无线资源负载发生改变中的至少一种情况, 确定用于控制用户设备访问 核心网的访问控制信息发生改变。
在本发明实施例中, 可选地, 该访问控制信息包括核心网域访问控制 DSAC信息、寻呼允许访问控制 PPAC信息和注册访问控制信息中的至少一 种信息; 但本发明实施例并不限于此, 例如, 该访问控制信息也可以是其 它访问控制信息, 比如基于业务类型的对核心网域的访问控制信息等。
下面将结合图 2A至图 4, 详细描述确定访问控制信息发生改变的方法
110。
图 2A 示出了根据本发明实施例的确定访问控制信息发生改变的方法
110的示意性流程图,该方法 110可由用户设备的第二服务无线接入网节点 执行, 例如由 RNC执行。
S111 , 接收该用户设备的第一服务无线接入网节点或该第一服务无线 接入网节点所连接的核心网节点发送的第一重定位请求 ( Relocation Required/Relocation Request )消息, 该第一重定位请求消息包括该第一服务 无线接入网节点所连接的核心网节点的全局核心网标识。 S 112 , 根据该第一服务无线接入网节点所连接的核心网节点的全局核 心网标识, 与该用户设备的第二服务无线接入网节点所连接的核心网节点 的全局核心网标识不同, 确定用于控制用户设备访问核心网的访问控制信 息发生改变。
在如图 2Α所示的上述方法 110中, RNC可以通过第一服务无线接入 网节点和第二月良务无线接入网节点所连接的核心网节点的全局核心网标识 ( Global CN ID )不同, 确定用户设备的服务无线接入网节点所连接的核心 网节点发生改变, 进而确定访问控制信息可能发生改变。
应理解, 在本发明实施例中, 重定位请求在 LTE网络中也可称为切换 请求 ( Handover Required或 Handover Request ), 本发明实施例仅以重定位 请求为例进行说明, 但本发明并不限于此。
在本发明实施例中, 该第一服务无线接入网节点是指用户设备发生 'J、 区变更或者切换过程中,在小区变更或者切换前为 UE提供服务的无线接入 网节点或者源无线接入网节点; 该第二服务无线接入网节点是指用户设备 发生小区变更或者切换过程中,在小区变更或者切换后为 UE提供服务的无 线接入网节点或者目标无线接入网节点。
可选地, 服务无线接入网节点包括无线网络控制器 RNC、 基站或基站 控制器 BSC; 用户设备的服务无线接入网节点所连接的核心网节点包括 GPRS服务支持节点 SGSN、 移动性管理实体 MME或移动交换中心 MSC。
在本发明实施例中, RNC也可以通过接收到的重定位请求消息中包括 的控制访问信息, 与当前的核心网节点的访问控制信息不同, 确定用于控 制用户设备访问核心网的访问控制信息发生改变。 具体地, 如图 2B所示, 该方法 110可由用户设备的第二服务无线接入网节点执行, 例如由 RNC执 行。
S113 , 接收该用户设备的第一服务无线接入网节点或该第一服务无线 接入网节点所连接的核心网节点发送的第二重定位请求消息, 该第二重定 位请求消息包括该第一服务无线接入网节点所连接的核心网节点的访问控 制信息。
5114 , 根据该第一服务无线接入网节点所连接的核心网节点的访问控 制信息, 与该用户设备的第二服务无线接入网节点所连接的核心网节点的 访问控制信息不同, 确定用于控制用户设备访问核心网的访问控制信息发 生改变。
应理解, 用户设备的第二服务无线接入网节点可以根据目前协议内容, 获取小区变更或者切换后为 UE提供服务的第二服务无线接入网节点的标 识、 访问控制信息等, 为了筒洁, 在此不再赘述。
在本发明实施例中, 当用户设备在与网络设备通信过程中, 没有发生 小区变更或者切换, 但核心网节点的访问控制信息发生变化时, 网络运营 管理( Operation And Managment ) 中心节点通常会发送通知消息, 因此, 服务无线接入网节点根据该通知消息, 也可以确定用于控制用户设备访问 核心网的访问控制信息发生改变, 具体地, 该方法 110如图 3所示。
5115 , 接收网络运营管理中心节点发送的通知消息, 该通知消息包括 该用户设备的服务无线接入网节点所连接的核心网节点的访问控制信息。
5116, 根据该通知消息确定用于控制用户设备访问核心网的访问控制 信息发生改变。
在本发明实施例中, 在用户设备与网络设备通信过程中, 服务无线接 入网节点还可以根据当前为 UE提供服务的小区的无线资源负载情况发生 改变, 确定用于控制用户设备访问核心网的访问控制信息发生改变。 例如, 当服务小区的无线资源负载状态从轻载 ( light load或者 normal load )状态 变成重载( heavy load )状态时, 则可以通过更新访问控制信息(例如从 not barred更新为 barred ), 来限制用户设备在该小区中由于发起新业务而消耗 更多的无线资源; 当服务小区的无线资源负载从重载状态变成轻载状态时, 可以通过更新访问控制信息(例如从 barred更新为 not barred ) ,来允许用户 设备在该小区中由于发起新业务引起更多的无线资源消耗。
因此, 在服务无线接入网节点确定用于控制用户设备访问核心网的访 问控制信息发生改变后, 服务无线接入网节点路通过 DCCH向用户设备发 送 RRC信令, 以指示访问控制信息发生改变, 从而使得用户设备能够及时 更新访问控制信息, 并能够正确地确定是否访问核心网, 由此能够有效控 制核心网节点的负载, 提升系统性能。
在上述各实施例中, 服务无线接入网节点在确定用户设备的服务无线 接入网节点所连接的核心网设备节点的访问控制信息发生改变时, 主动通 过 DCCH信令指示用户设备访问控制信息可能发生变化。 为了能够减少网 络设备给用户设备下发专用信令的消耗, 服务无线接入网节点可以先不主 动将更新的访问控制信息发给用户设备, 或不主动告知用户设备访问控制 信息可能发生变化, 直到收到用户设备对需要限制的核心网设备发起信令 连接时, 服务无线接入网节点再通过专用信令指示用户设备访问控制信息 可能发生改变。
具体地, 如图 4所述, 可选地, 根据本发明实施例的用于控制访问核 心网的方法 100如下所述。
S 110 , 确定用于控制用户设备访问核心网的访问控制信息发生改变。 S130, 接收该用户设备发送的用于与核心网域建立信令连接的初始直 传消息。
S140, 确定该用户设备能够访问的该核心网域的所有核心网节点处于 受限状态。
S120, 通过该专用控制信道 DCCH向该用户设备发送该无线资源控制 RRC信令, 该 RRC信令用于指示该访问控制信息发生改变, 以便于该用户 设备更新该访问控制信息。
可选地, 该核心网域包括电路交换域( Circuit Switch Domain )或分组 交换域 ( Packet Switch Domain )。 例如, 用户设备与 CS域存在信令和业务连接, 并且用户设备中存储的 PS域访问控制信息是"不受限或可以访问", 在 CS业务通话过程中, 由于 核心网的访问控制信息发生变化, PS域的访问控制信息由 "不受限"变更为
"受限或禁止访问"。然而用户设备由于无法读取系统广播消息,也无法从服 务无线接入网节点中获得更新的 PS域的访问控制信息, 当用户设备有 PS 域数据包想要发送时, 用户设备会发起初始直传消息, 以与 PS域核心网建 立业务连接。
当用户设备的服务接入网节点收到发往 PS 域的第一条信令建立请求 时,若服务无线接入网节点检测并确定该用户设备的 PS域核心网节点处于 过载或者处于 "受限或禁止访问"状态,服务无线接入网节点可以将更新的核 心网访问控制信息通过 RRC信令发送该用户设备。 该 RRC信令可以是上 述实施例中提到的任一专用控制消息, 也可以是信令连接释放(Signaling Connection Release ) 消息或分组域分配丟弃 ( Packet Assignment Reject ) 消 息。
应理解, 上文中结合图 2A至图 4, 详细描述确定访问控制信息发生改 变的方法 110, 但本发明并不限于此, 服务无线接入网节点也可以根据其它 信息或参数, 确定用于控制用户设备访问核心网的访问控制信息可能发生 改变。 例如, 服务无线接入网节点可以根据核心网节点的负荷变化情况、 用户设备的服务小区的变化情况等, 确定访问控制信息发生改变; 又例如, 目标 RNC也可以确定在切换过程中与源 RNC连接到不同的 SGSN和 /或 MSC , 由此确定访问控制信息发生改变; 或目标 RNC也可以确定在切换过 程中发生了跨 MSC/SGSN节点的切换, 由此确定访问控制信息可能发生改 变等。
在 S120中,服务无线接入网节点可以通过专用控制信道 DCCH向用户 设备发送 RRC信令, 该 RRC信令可以包括改变后的访问控制信息, 以指 示用户设备访问控制信息发生改变, 用户设备收到该 RRC信令后, 可以对 存储的访问控制信息进行更新; 该 RRC信令也可以携带其它信息, 仅指示 访问控制信息发生改变, 此时, 用户设备接收到该 RRC信令后, 可以清除 原先保存的访问控制信息, 从而用户设备能够正确地确定是否访问核心网, 由此能够有效控制核心网节点的负载, 提升系统性能。 下面将结合图 5分 别进行描述。
在图 5所示的 S121中,可选地,通过专用控制信道 DCCH向用户设备 发送无线资源控制 RRC信令, 包括:
通过该 DCCH向该用户设备发送该 RRC信令, 该 RRC信令包括用于 该用户设备更新的访问控制信息或指示该用户设备清除访问控制信息的指 令。
例如, 当 RNC确定当前服务小区所连接到的核心网结点的访问控制信 息改变时, RNC可以构造一个 RRC信令, 该 RRC信令包括更新后的访问 控制信息, 例如可以包括 DSAC信息和 /或 PPAC信息, 并在 DCCH上发送 给诸如处于 CELL_DCH状态的 UE; 该 UE在接收到这个包括 DSAC信息 和 /或 PPAC信息的 RRC信令后, 可以清除自己原先存储的访问控制信息, 并存储更新后的访问控制信息。 可选地, 该 DSAC信息和 /或 PPAC信息为 UE当前所选择的公共陆地移动网络( Public Land Mobile Network, 筒称为 "PLMN" )的 DSAC信息、 PPAC信息和注册访问控制信息中的至少一种信 息。 又例如, 该 RRC信令可以包括指示该用户设备清除访问控制信息的指 令。 该 UE在接收到该指令的 RRC信令后, 可以清除自己原先存储的访问 控制信息。
在本发明实施例中,可选地,该通过该 DCCH向该用户设备发送该 RRC 信令, 该 RRC信令用于指示该用户设备更新的访问控制信息或用于指示该 用户设备清除访问控制信息的指令, 包括:
通过该 DCCH向该用户设备发送该 RRC信令, 其中, 该 RRC信令中 的所有可选信元配置为空, 用于指示该用户设备更新的访问控制信息, 或 用于指示该用户设备清除访问控制信息的指令; 或
通过该 DCCH向该用户设备发送该 RRC信令, 其中, 该 RRC信令中 的信元配置为预配置值, 用于指示该用户设备更新的访问控制信息, 或用 于指示该用户设备清除访问控制信息的指令。
具体而言, 在本发明实施例中, 可选地, 该通过该 DCCH向该用户设 备发送该 RRC信令, 其中, 该 RRC信令中的所有可选信元配置为空, 用 于指示该用户设备更新的访问控制信息, 包括:
通过该 DCCH向该用户设备发送该 RRC信令, 其中, 该 RRC信令中 的所有可选信元配置为空, 用于指示该用户设备存储的访问控制信息从"禁 止接入 "/"不禁止接入"更新为"不禁止接入"; 或
用于指示该用户设备存储的访问控制信息从"禁止接入" /"不禁止接入" 更新为"禁止接入"。
例如, RNC发送给用户设备一条特殊格式的 RRC信令, 当这条 RRC 信令中的所有可选信元都设置为空时, 代表清除用户设备中存储的访问控 制信息, 或者代表将用户设备中存储的访问控制信息从"禁止接入 ( barred ),,/"不禁止接入 ( not barred ),,更新为"不禁止接入( not barred ),,, 或者代表将用户设备中存储的访问控制信息从"不禁止接入 ( not barred ),,/"禁止接入(barred ),, 更新为 "禁止接入(barred ),,。 用户设备通 过接收到这条可选信元都设置为空的 RRC消息, 可以根据上述定义的情况 来更新用户设备存储的访问控制信息, 比如这条特殊格式的 RRC信令可以 UTRAN移动性信息消息(UTRAN mobility Information )。 因此, 通过本 实施例, 可以不修改当前 RRC信令格式和信元结构的方式, 而实现在网络 设备控制下对用户设备存储的访问控制信息变量进行更新的功能。
在本发明实施例中,可选地,该通过该 DCCH向该用户设备发送该 RRC 信令, 其中, 该 RRC信令中的信元配置为预配置值, 用于指示该用户设备 更新的访问控制信息, 或用于指示该用户设备清除访问控制信息的指令, 包括:

例如, RNC发送给用户设备一条特殊格式的 RRC信令, 通过将这条 RRC消息中某一个具有其他含义的信元设置为特殊的预留值, 可以用于代 表清除用户设备中存储的访问控制信息, 或者代表将用户设备中存储的访 问控制信息从 "禁止接入(barred ) "/"不禁止接入 ( not barred ) "更新为"不 禁止接入( not barred ) ",或者代表将用户设备中存储的访问控制信息从"不 禁止接入 ( not barred ),,/"禁止接入 ( barred ),, 更新为 "禁止接入 ( barred ),,。 用户设备通过接收到这条特殊预留值的 RRC消息, 可以根据上述对预留值 的定义的情况来更新用户设备存储的访问控制信息。 比如这条特殊格式的 RRC信令可以是 UTRAN移动性信息消息( UTRAN mobility Information ), 从而可以通过这条消息中的某个信元, 预留一些取值代表对访问控制信息 的更新。 这里以 C-RNTI为例进行说明, 应理解也可以采取其他信元, 例如 U-RNTL H-RNTL E-RNTI等消息中的其他信元。
比如, 在预配值为第一值即 C-RNTI=0000000000000000时, 可以代表 将用户设备中存储的访问控制信息从"禁止接入( barred )"/"不禁止接入( not barred ) "更新为"不禁止接入 ( not barred ) "; 或者在预配值为第二值即 C-RNTI=0000000000000001 时, 可以代表将用户设备中存储的访问控制信 息从"禁止接入 ( barred ),,/"不禁止接入 ( not barred ),,更新为"禁止接入 ( barred ) "; 或者在预配值为第三值即 C-RNTI=0000000000000002时, 可 以代表清除用户设备中存储的访问控制信息。 从而, 当支持该功能的用户 设备收到一个 UTRAN mobility information的 RRC消息后, 当这条消息中 的 New C-RNTI=0000000000000002时, 则可以对用户设备中存储的访问控 制信息进行清除;或者当这条消息中的 New C-RNTI=0000000000000001时, 则可以对用户设备中存储的访问控制更新为"禁止接入(barred ) "; 或者当 这条消息中的 New C-RNTI=0000000000000000时, 则可以对用户设备中存 储的访问控制更新为 "不禁止接入(not barred ) "。 通过本实施例, 可以不 修改当前 RRC信令格式和信元结构的方式, 实现在网络设备控制下对用户 设备存储的访问控制信息变量进行更新的功能。
应理解, RNC也可以在确定访问控制信息没有改变时, 例如, 在确定 切换过程中目标 RNC与源 RNC连接到系统的 SGSN和 /或 MSC时, 或在 确定切换过程中没有发生跨 MSC/SGSN节点的切换时, 或在确定用户设备 的服务小区的无线资源负载发生改变时等, 通过 DCCH向 UE发送包括最 新访问控制信息的 RRC信令, 以筒化网络侧行为。
可选地, 该 RRC信令包括通用移动通信系统陆地无线接入网 ( UMTS Terrestrial Radio Access Network, 筒称为" UTRAN" )移动性信息 ( UTRAN Mobility Information )消息、 无线资源控制重配置消息、寻呼类型 2 ( Paging Type 2 ) 消息、 信令连接释放 ( Signalling Connection Release ) 消息或分组 域分配丟弃(Packet Assignment Reject ) 消息。 该无线资源控制重配置消息 例如为无线 7 载 ( Radio Bearer )重配置消息、 传输信道重配置消息或物理 信道重配置消息等。

向该用户设备发送第一寻呼类型 2消息, 该第一寻呼类型 2消息指示 系统广播消息发生变更。 例如, 当 RNC确定当前服务小区所连接到的核心网结点的访问控制信 息改变时, RNC可以向 UE发送第一寻呼类型 2消息, 该第一寻呼类型 2 消息指示系统广播消息发生变更; UE收到该第一寻呼类型 2消息后, 可以 清除当前存储的访问控制信息, 例如将当前存储的 DSAC信息和 /或 PPAC 信息清空。
在图 5所示的 S123中,可选地,通过专用控制信道 DCCH向用户设备 发送无线资源控制 RRC信令, 包括:
