Description
一种 CSG小区信息更新和接入控制的方法和设备 本申请要求于 2011年 3月 14日提交中国专利局、 申请号为 201110060232.2、 发明名称为 "一种 CSG小区信息更新和接入控制的方法和设备"的中国专利申 请的优先权, 其全部内容通过引用结合在本申请中。 技术领域
本发明涉及通信领域,尤其涉及一种 CSG小区信息更新和接入控制的方法 和设备。 背景技术
CSG ( Closed Subscriber Grou ,闭合用户组 )是覆盖有限区域的小型网络, 服务于特定的用户, 称为闭合用户组, 这种网络只有属于该组内的用户才能接 入。 终端在接入网络之前, 先从 CSG小区读取 CSG小区的标识, 将读取的 CSG小区的标识与终端自身存储的 CSG列表中的 CSG小区的标识进行匹配, 从而判断是否能够接入该 CSG小区。
现有技术提供了一种由网络侧发起的 CSG列表更新的方法, 该方法中, 当 ΜΜΕ ( Mobile Management Entity, 移动管理实体)和终端的允许接入列表 ( Allowed CSG List,以下简称 CSG列表)不一致时,通过 HSS( Home Subscriber Server,归属用户服务器)对网络侧的 CSG列表进行更新,通过 PDN-GW( Public Data Network-Gateway,公共数据网网关)用户面对用户侧的 CSG列表进行更 新。 当终端的 CSG列表需要更新时, 如果终端正处在连接态, 则直接通过用 户面传输 CSG列表给该终端, 终端对自身的 CSG列表进行更新; 如果终端处 在空闲 (IDLE ) 态, 可以触发寻呼, 将更新的 CSG列表传给终端。
但是,如果由于某些原因无法寻呼到终端, 则在某一段时间内将无法保持 网络侧的 CSG列表与用户设备侧一致, 从而导致终端不能合理的接入网络资 源, 降低了网络资源的利用效率。
随着多样化的数据业务的开展, 引入了大量机器类型通信(Machine Type Communications, MTC, 即 M2M )。 艮多 MTC终端部署不受运营商控制, 例 如, 由国家电网、煤气公司或用水公司统一部署的 MTC终端 ,仅仅通过 USIM
( Universal Subscriber Identity Module, 通用用户识别模块)卡的方式连接到 运营商的网路中, 因此运营商无法准确识别每一个 MTC终端 , 当 MTC终端 需要接入网络时, 会釆用舍近求远的接入方式, 即舍弃近处的家庭基站, 而去 连接较远的宏基站。即, 因家庭基站的部署与 MTC终端的部署很难彼此协调, 无法直接借用上述方法实现对 MTC终端的接入控制, 从而造成了 MTC终端 无法选择合适的接入节点。
由此可见, 对于 MTC终端, 因其与家庭基站的部署艮难彼此协调, 因而 无法通过现有技术的方式实现 MTC终端的接入控制; 对于其它终端, 因存在 网络侧的 CSG列表与终端侧不一致的情况, 使终端无法合理接入。 即使能够 实现 MTC终端与家庭基站的部署的彼此协调,但仍存在网络侧的 CSG列表与 终端侧不一致的情况, 使 MTC终端无法合理接入。
现有技术还提供了一种终端的接入控制方法, 该方法中, 终端在本地接入 时, 忽略基站的 CSG列表而是直接进行接入, 家庭基站将终端的相关信息发 送到核心网, 由核心网进行认证, 从而允许或者拒绝终端进行接入。
可以看出,这种方法忽略了 CSG列表的限制,对于 MTC终端或其它终端 来说,都出现恶意终端不断尝试接入,从而对家庭基站的无线接入造成较大的 影响, 而遵守 CSG协议的终端并不会尝试接入网络, 因此该方法依然无法使 终端合理的接入网络资源并有效的利用网络资源。 发明内容

为使本发明的上述目的、特征和优点能够更加明显易懂, 下面结合附图对 本发明的具体实施方式做详细的说明。
本发明实施例中, MTC终端接收 CSG小区发送的小区信息, 根据接收的小 区信息得到可以接入的 CSG小区信息, 并上报给核心网,核心网对 MTC终端得 到的可以接入的 CSG小区信息进行确认并发送通过确认得到的允许接入的 CSG 小区信息或者可以接入的 CSG小区信息的确认信息给 MTC终端, MTC终端根据 允许接入的 CSG小区信息或者可以接入的 CSG小区信息的确认信息对 CSG小区 信息进行更新,从而解决了由于 MTC终端无法寻呼,造成网络侧和 MTC终端侧 CSG小区信息不一致的问题, 保证了 MTC终端 CSG小区信息的及时更新, 使得 MTC终端可以接入合适的网络设备, 合理的利用网络资源。 其中, MTC终端根 据接收到的小区信息所得到的可以接入的 CSG小区信息,以及核心网返回的允 许接入的 CSG小区信息, 通常可以用 CSG列表(如 Al lowed CSG L i s t )形式 表现。 本发明实施例中的 CSG列表可以用于记录该 MTC可接入的网络节点的 CSG标识, 还可以进一步包括其他信息, 如接入模式信息。
下面结合附图对本发明实施例进行详细描述。
实施例一
本发明实施例一以 LTE ( Long Term Evolut ion, 长期演进) ***架构为 例, 提出了一种 CSG列表的更新流程, 该流程可包括以下步骤:
步骤 201 , MTC终端接收 CSG小区发送的小区信息, 根据接收的小区信息 得到 CSG列表。
具体的, MTC终端可通过小区测量或探测过程接收 CSG小区发送的信息, 并可根据接收到的 CSG小区的信息生成可以接入的 CSG列表。 MTC终端可通过 预先设置的方式,例如在空闲状态时以一定周期对 MTC终端周围的网络接入节 点进行测量, 也可以通过设定特定事件来触发测量。 CSG列表中可包括 MTC终 端能够探测到的一个或多个小区的相关信息。该步骤中 MTC终端接收的小区信 息以及据此生成的可以接入的 CSG列表的具体实现可釆用现有方式。
步骤 202 , MTC终端将可以接入的 CSG列表发送给基站。
步骤 203 , 基站将该可以接入的 CSG列表发送给 MME。
步骤 204 ,丽 E通过与 HSS交互,根据 HSS存储的该 MTC终端相关信息 (如 签约信息), 对该 MTC终端发送的可以接入的 CSG列表进行确认, 并且通过确 认得到允许接入的 CSG列表或者终端发送的可以接入的 CSG列表的确认信息。
具体的, 丽 E对该 MTC终端发送的可以接入的 CSG列表进行确认时, 首先 发送获取 MTC终端相关信息(如签约信息)的请求给 HSS , 并在获取到 HSS返 回的相关信息后,根据获取的 HSS返回的相关信息对 MTC终端发送的可以接入 的 CSG列表进行确认。 比如, MTC终端的签约信息规定了该 MTC终端可接入的 小区的要求,若丽 E判断该 MTC终端上报的 CSG列表中的某个小区符合该签约 信息的要求时,对该 MTC终端上报的 CSG列表的该小区进行确认通过, 否则不 予确认通过。 MME与 H S S之间的消息可由 PGW ( PDN-Ga teway, 分组数据网关) 转发。
MME根据确认的结果, 可以生成允许接入的 CSG列表, 该 CSG列表可以记 录丽 E经过确认允许终端使用的 CSG小区的标识,还可以进一步包括终端接入 CSG小区相关的其他信息。 丽 E根据确认的结果, 也可以生成终端侧上报的可 以接入的 CSG小区信息的确认信息,该确认信息可以指示允许或者不允许终端 侧根据其上报的可以接入的 CSG列表进行更新。
步骤 205 , MME指示 HSS根据确认的结果更新其所存储的该 MTC终端的 CSG
列表。
具体的, 丽 E可以将允许接入的 CSG列表或者可以接入的 CSG列表的确认 信息发送给 HSS , HSS根据固 E发送的 CSG列表或确认信息, 更新其所存储的 该 MTC终端的 CSG列表。 丽 E可以通过 PGW转发 CSG列表或确认信息到 HSS。
步骤 206 , 固 E通过控制面 (即通过控制面信令)将允许接入的 CSG列表 或者可以接入的 CSG列表的确认信息发送给 MTC终端, MTC终端根据该确认信 息更新其上的 CSG列表,即根据步骤 204中确认的 CSG列表更新该 MTC终端原 有的 CSG列表。
步骤 206的一种替代方案是: 固 E将允许接入的 CSG列表或者确认信息发 送给 HSS , HSS通过用户面 (即通过用户面信令)发送给 MTC终端; 步骤 206 的又一种替代方案是: 由 HSS更新其所存储的 MTC终端的 CSG列表之后,根据 更新结果生成对应允许接入的 CSG列表或者确认信息,并通过用户面信令发送 给 MTC终端。
MTC终端接入 CSG小区时, 可以从更新后的 CSG列表中的 CSG小区进行接 入, 具体的, MTC终端可以从 CSG列表中选取一个 CSG小区进行接入, 也可以 从探测到的 CSG小区中选取一个,并查找选取的 CSG小区标识是否在更新后的
CSG列表中, 如果存在则接入该 CSG小区。
通过以上流程可以看出, MTC终端主动上报通过小区测量或探测等方式得 到的 CSG 列表到核心网侧进行确认, 一方面, 核心网在确认后更新网络侧该 MTC终端的 CSG列表, 另一方面使该 MTC终端在得到核心网的确认通知后进行 本地 CSG列表更新, 从而可以及时对 MTC终端和网络侧的 CSG列表进行更新, 解决了 MTC终端和家庭基站共同部署时的协同问题,保证了 MTC终端 CSG列表 的及时更新,使得 MTC终端可以接入合适的网络资源, 进而可合理利用网络资 源。
实施例二
本发明实施例二提出了一种接入控制方法,如图 3所示, 该方法的流程可 包括以下步骤:
步骤 301 , MTC终端接收基站发送的***信息, 该***信息中携带有允许 接入指示信息。
具体的, 该基站可以是家庭基站, 或其他具备 CSG管理功能的通信基站, 可在基站的***信息中设置 MTC终端允许接入指示信息 (如 MTC Al l owed ), MTC终端允许接入指示信息用于指示允许 MTC终端接入该家庭基站。 该 MTC终 端允许接入指示信息可以为 1比特的标识信息, 其值可为 0或 1 , 当其为 0时 表示允许 MTC终端接入, 当其为 1时表示不允许 MTC终端接入, 反之亦然。 该 MTC终端允许接入指示信息可以携带于 S IB1—1 3***信息中的一种, 或其它类 型的***信息, 如 MIB/S IB2等。
图 4示出了一种 S IB1***信息格式, 其中设置有 MTC终端允许接入指示 信息选项。 如图 4所示, 在 S IB1***信息中增加了 MTC终端允许接入指示信 息( csg-MTC enab led )。 当 MTC终端允许接入指示的值设置为允许时, 该小区 允许 MTC终端接入。
步骤 302 , MTC终端根据接收到的***信息中携带的 MTC允许接入指示信 息判断被允许接入所述基站时, 接入该家庭基站或家庭基站小区, 或 /和, 将 该家庭基站或家庭基站小区加入自身的 CSG列表中。
家庭基站可以通过增加 MTC允许接入指示信息项来指示允许 MTC终端接 入, 并通过不在***信息中增加 MTC 允许接入指示信息项来指示不允许 MTC 终端接入。 或者, 家庭基站可以在***信息中增加 MTC允许接入指示信息, 通 过将其值设置为表明是否允许 MTC终端接入的参数值, 例如, 参数值为 1表示 允许 MTC终端接入, 参数值为 0表示不允许 MTC终端接入, MTC终端接收到该 家庭基站发送的***信息且参数值为 0后,不会接入该家庭基站或家庭基站小 区, 也不会将该家庭基站或家庭基站小区加入该 MTC终端的 CSG列表。
通过以上流程可以看出,通过在基站发送的***消息中设置 MTC终端允许 接入指示信息,在不违反现有流程的基础上,使得 MTC终端可以就近接入合适 的服务小区,合理的利用网络资源, 并可进一步避免 MTC终端直接接入时恶意 MTC终端攻击家庭基站的问题。
需要说明的是, 本发明的上述各实施例中, 家庭基站也可由基站代替。 另 夕卜, MTC终端也可以由其它类型的终端代替, 这种情况下, 与现有技术中由网 络侧发起 CSG列表更新的方法相比,解决了由网络侧发起的 CSG列表更新方式 中, 终端侧可能接收不到网络侧更新的 CSG 列表的问题; 与现有技术中忽略
CSG列表而直接进行接入的方法相比, 使终端可以根据***消息中携带的接入 指示信息而进行合理接入。
还需要说明的是,在上述本发明实施例中, 可接入家庭基站小区信息均以 CSG列表为例进行说明, 在实际应用中, 也可能是其他用于家庭基站接入控制 的信息。
基于与上述实施例一相同或相似的技术构思,本发明实施例还提出了一种 终端和网络侧设备, 分别如图 5和图 6。
如图 5所示, 本发明实施例提供的终端可以是 MTC终端, 该终端可包括: 获取单元 11 , 用于接收 CSG小区发送的小区信息, 根据接收的小区信息 得到可以接入的 CSG小区信息;
