步骤 110, 网络侧设备将用户设备 UE加入到封闭用户组 CSG小区的 准入用户列表, 形成更新的准入列表, CSG小区的准入用户列表包括 CSG 小区允许接入的 UE标识;
步骤 120, 网络侧设备在 UE确定 CSG小区为自身可接入的小区、 并 且在该 UE将该 CSG小区加入到该 UE的准入小区列表之后, 根据网络侧 设备更新后的准入列表对 UE执行准入。
本发明实施例提供的技术方案, 使得网络侧设备在某个 CSG小区的准 入用户列表中增加 UE的情况下, 网络侧和 UE侧保持准入信息的一致性, 并以新的准入列表执行准入, 提高了 CSG功能的可用性和完善性。 实施例二 本发明第二实施例涉及一种准入方法。 本发明实施例二包括两种实现 方式, 图 2为本发明第二实施例实现方式 A流程示意图。 如图 2所示, 本 步骤 210, 将 UE加入 CSG小区的准入用户列表;
本步骤中, CSG小区所对应的接入点 AP设备将 UE标识加入到该 CSG 小区的准入用户列表, 形成 CSG小区的新的准入列表;
可以理解的是, 该接入点 AP设备将 UE标识加入到该 CSG小区的准 入用户列表可以是根据运营商的指令而进行操作的。 在接入点 AP设备将 UE加入到 CSG小区的准入用户列表之后, 可以形成该 CSG小区的新的准 入列表。 另外, 该接入点 AP设备可以对新的准入列表进行保存。 比如, 原 来某个 CSG小区(比如 cell 1 )只允许 UE 1和 UE 2的接入, 而 AP设备可 以增加 UE 3到该小区的准入列表中,形成新的包含 UE 1至 UE 3的准入列 表, 并予以保存。
AP设备在以后判断某个向该 CSG小区发起准入请求的 UE能否准入 时, 可以采用更新后的准入列表。 这意味着, 在此后如果 UE向该 CSG小 区发起准入请求, 该 CSG会根据协议同意该 UE的准入请求;
步骤 220, UE进行 CSG小区搜索;
一般而言, 有 CSG功能的 UE会进行周期性的 CSG小区搜索。 并且, 该周期性 CSG小区搜索的频率可以由用户对 UE进行设置, 也可以在出厂 时进行缺省设置。 即, UE可以根据预先设定的频率进行周期性的 CSG小 区搜索。
步骤 230, UE判断所搜索到的 CSG小区中是否有该 UE的准入小区; UE通过将所搜索到的 CSG小区的标识与 UE的准入小区列表进行比 对, 来判断所搜索到的 CSG小区中是否有该 UE的准入小区。 如果所搜索 到的 CSG小区的标识有与该 UE的准入小区列表中的标识一致的, 则认为 所搜索到的 CSG小区中有该 UE的准入小区, 否则, 认为所搜索到的 CSG 小区中没有该 UE的准入小区。
具体的, 有 CSG能力的 UE中包含该 UE可以准入的 CSG小区列表, 该小区列表中的小区可能是一个或多个。
当然, 实际情况中, 也可能 UE没有搜索到 CSG小区, 则无需进行本 步骤的判断, 在发明实施例中不对此分支进行说明。
假设 UE搜索到的小区中只有一个 CSG小区, cell 0, 则将 cell O的标 识与 UE自身的准入小区列表中的 CSG小区的标识进行对比。 如果 UE的 准入小区列表中有 cell 0的标识, 则 UE进行步骤 290, 直接向 cell 0发起 准入。 如果 UE的准入小区列表中没有 cell 0的标识, 或者说该 cell 0的标 识与 UE的 CSG小区列表中的任何一个 CSG标识都不相同,则需要进行以 下步骤。 在 UE搜索到的小区中只有一个 CSG小区的情况下, 后续则默认 确定该 cell 0为所搜索到的信号最强的 CSG小区。 在本实施例中也不对此 作更详细的说明。
假设 UE搜索到有 CSG小区 cell 1和 cell 2存在, 下面以 cell 1为例说 明和 UE自身的准入小区列表进行比对的过程, 对 cell 2的处理可以参照执 行。
具体的, UE可以将该 cell 1的标识与 UE自身的 CSG列表进行比对, 查看 UE自身的 CSG小区列表中是否有 cell 1的标识。 如果 UE的 CSG小 区列表中有 cell 1的标识, 则 UE进行步骤 290, 直接向 cell 1发起准入。 但是, 如果 UE的准入小区列表中没有 cell 1的标识, 或者说该 cell 1的标 识与 UE的 CSG小区列表中的任何一个 CSG标识都不相同,则需要进行以 下步骤。 本发明实施例中, 支设 cell 1和 cell 2均不在该 UE的准入小区列 表中。
步骤 240, UE确定所搜索到的信号最强的 CSG小区;
UE在搜索 CSG小区过程中, UE可以获取 CSG小区的标识,以及 CSG 小区的信号强度。 在搜索到的 CSG小区存在多个的情况下, UE可以对所 搜索到的 CSG小区的信号强度进行比较,找出所有搜索到的 CSG小区中信 号最强的 CSG小区。 在搜索到的 CSG小区存在一个的情况下, UE默认该 CSG小区为信号最强的 CSG小区, 在此不详细描述。
仍然以搜索到 cell 1和 cell 2为例,假设 cell 1和 cell 2都不在该 UE的 准入小区列表中。 此种情况下, UE可以比较 cell 1和 cell 2的信号强度, 从而确定信号最强的一个。本实施例中,假设信号最强的 CSG小区是 cell 1。
步骤 250, UE向所搜索到的信号最强的 CSG小区发起驻留请求; 本步骤中, UE可以向 cell 1发起驻留请求。
步骤 260, 确定 UE能成功驻留到所搜索到的信号最强的 CSG小区; 可以理解的是,根据 CSG的特性可以得知,如果该 CSG小区允许了该
UE的驻留请求,可以将该 CSG小区认为是该 UE的可以接入的小区。根据 前面的描述可知, 该 UE的准入小区列表中并没有该 cell 1的标识。
步骤 270, UE将该 CSG小区加入到 UE的准入列表;
本步骤中, UE将该 cell 1的标识加入到 UE的准入列表, 从而更新了 UE的准入小区列表。 这样, 后续 UE进行 CSG小区搜索时, 如果再搜索到 cell 1 , 则可以立即辨认出 cell 1是 UE的准入小区列表中的小区, 可以发起 准入。
步骤 280, 接入点 AP设备根据更新后的准入列表对 UE执行准入; 在 UE形成了更新的准入小区列表之后, UE的准入小区列表中包含 cell 1的标识, 而在网络侧, 已将该 UE加入 cell 1的准入用户列表, 即, 网络 侧和 UE侧保持了准入信息的一致性。 此后, 从网络侧的角度而言, AP设 可见, 本发明实施例提供的技术方案, 在网络侧设备在某个 CSG小区 的准入用户列表中增加 UE的情况下,通过 UE的主动搜索、尝试驻留机制, 使得 UE侧及时更新准入小区列表,以保持和网络侧更新后的准入信息的一 致性。 这样, 对网络侧而言, 可以使用新的 CSG小区的准入用户列表执行 对 UE的准入, 对 UE而言, 可以以新的准入小区列表发起准入请求, 整体 而言, 由于网络侧和 UE侧关于准入信息保持了实时的一致性,避免现有技 术中的缺陷, 从而提高了 CSG功能的可用性和完善性。
在第二实施例中,还包括实现方式 B,相对于第二实施例的实现方式 A 而言, 该实现方式 B, 不经过实现方式 A中步骤 230的判断, 直接确定所 搜索到的信号最强的 CSG小区。 即, 该 UE不判断所搜索到的 CSG小区中 是否有该 UE的准入小区, 在 UE进行 CSG小区搜索之后, 直接确定所搜 索到的信号最强的 CSG小区。 图 3为本发明第二实施例实现方式 B流程示 意图, 如图 3所示, 本发明第二实施例实现方式 B。 其具体的步骤包括: 步骤 310, 将 UE加入 CSG小区的准入用户列表;
其中, 具体描述可以参见第二实施例;
步骤 320, UE进行 CSG小区搜索;
其中, 具体描述可以参见第二实施例, 在本实施例中也以所搜索到的
CSG小区包括 cell 1和 cell 2为例;
步骤 330, UE确定所搜索到的信号最强的 CSG小区;
其中, 具体描述可以参见第二实施例, 假设确定所搜索到的信号最强 的 CSG小区为 cell 1 ;
步骤 340, UE向所搜索到的信号最强的 CSG小区发起驻留请求; 其中, 具体描述可以参见第二实施例, 该 UE向 cell 1发起驻留请求; 步骤 350, 确定 UE能成功驻留到所搜索到的信号最强的 CSG小区; 其中, 具体描述可以参见第二实施例;
步骤 360, UE将该 CSG小区加入到 UE的准入列表;
此时,根据该 cell 1是否已经在该 UE的准入小区列表中,分两种情况。 当 cell 1已经在该 UE的准入小区列表中时, 则将 cell 1加入到该 UE的准 入小区列表不带来该 UE的准入小区列表的变化; 当 cell l不在该 UE的准 入小区列表中时, 则将 cell l加入到该 UE的准入小区列表, 会使该 UE的 准入小区列表发生变化;
步骤 370, 接入点 AP设备根据更新后的准入列表对 UE执行准入; 当在步骤 360中, 当该 cell 1 已经在该 UE的准入小区列表中时, 该
UE更新后的列表与更新前的列表相同, 而当该 cell 1不在该 UE的准入小 区列表中时, 该 UE更新后的列表中增加了该 cell 1。
本发明实施例实现方式 B可以适用于 UE到达新场所(该新场所存在 该 UE准入小区列表中的小区的几率很小)的场景, 在该种场景下, 采用直 接确定搜索到的信号最强的 CSG小区的实现方式, 可以减少判断的步骤和 时间, 也减少 UE的耗电。 实施例三
本发明第三实施例涉及一种准入方法。 图 4为本发明第三实施例流程 示意图。 如图 4所示, 本发明第三实施例的准入方法包括以下步骤:
步骤 410, 将 UE加入 CSG小区的准入用户列表;
其中, 具体描述可以参见第二实施例;
步骤 420, UE进行 CSG小区搜索;
其中, 具体描述可以参见第二实施例;
步骤 430, UE判断所搜索到的 CSG小区中有没有与 UE的准入列表中 一致的小区;
其中, 具体描述可以参见第二实施例;
步骤 440, UE确定所搜索到的信号最强的 CSG小区;
UE则对所搜索到的 CSG小区的信号强度进行比较, 找出所有搜索到 的 CSG小区中信号最强的 CSG小区。
在 UE找出所有搜索到的 CSG小区中信号最强的 CSG小区时,可以预 设一个 UE需要进行搜索的次数, 只有当搜索 CSG小区的次数达到该预设 的次数, 才能进行统计, 避免搜索的次数太少而不能达到统计的效果。 在本步骤中,可以将该预设的次数定义为第一预设次数。在 UE每一次 搜索 CSG小区时, 如果搜索到的 CSG小区为 1个, 则该 CSG小区就是信 号最强的 CSG小区, 如果搜索到的 CSG小区为多个, 则 UE比较这几个 CSG小区的信号强度, 确定其中信号最强的 CSG小区。 并且在多次搜索过 程中, UE记录每次确定的信号最强的 CSG小区的结果。 当 UE搜索 CSG 小区的次数达到该第一预设次数, 开始统计在该第一预设次数中, 被确定 为信号最强的 CSG小区的次数最多的 CSG小区。 UE根据统计结果确定该 被确定为信号最强的 CSG小区次数最多的 CSG小区为信号最强的 CSG小 区。 如果 UE搜索 CSG小区的次数没有达到该第一预设次数, 则不进行统 计。
以搜索到 cell 1、 cell 2和 cell 3为例, 假设 cell 1、 cell 2和 cell 3都不 在该 UE的准入小区列表中。此种情况下, UE可以比较 cell l、 cell 2和 cell 3的信号强度, 从而确定信号最强的一个。
假设第一预设次数为 10次, 每一次搜索时 UE记录当次搜索确定的信 号最强的 CSG小区, 在完成 10次搜索之后, 统计各个 CSG小区被确定为 信号最强的次数。 假设, 在 10次搜索完成之后, cell 1被确定为信号最强 的次数为 8次, cell 2被确定为信号最强的次数为 2次, cell 3被确定为信号 最强的次数为 0次, 则确定 cell 1为信号最强的 CSG小区。
在本步骤中, 还可以增加对经过统计为信号最强的 CSG小区进一步的 判定。判定在统计结果中,该信号最强的 CSG小区被确定为信号最强的 CSG 小区的次数是否超过第二预设次数。 如果超出该第二预设次数, 则认为该 CSG小区为信号最强的 CSG小区, 如果不能达到该第二预设次数, 则认为 在第一预设次数的搜索过程中, 不能找出信号最强的 CSG小区。 此种情况 下, UE需要可以重新开始 CSG搜索。
还以搜索到 cell 1、 cell 2和 cell 3, 并且 cell 1、 cell 2和 cell 3都不在 该 UE的准入小区列表中为例。 假设第一预设次数为 10次, 第二预设次数 为 7次。
假设, 在 10次搜索完成之后, cell 1被确定为信号最强的次数为 7次 及以上, 则确定 cell 1为信号最强的 CSG小区, 如果, cell 1被确定为信号 最强的次数为 7次以下,尽管在三个被搜索的 CSG小区中, cell 1被确定为 信号最强的小区的次数最多, 但是该次数不能达到第二预设次数, 则不能 确定 cell 1为信号最强的 CSG小区。 此种情况下, UE可以重新开始 CSG 搜索。
步骤 450, UE向所搜索到的信号最强的 CSG小区发起驻留请求; 其中, 具体描述可以参见第二实施例;
步骤 460, 确定 UE能成功驻留到所搜索到的信号最强的 CSG小区; 其中, 具体描述可以参见第二实施例;
步骤 470, UE将该 CSG小区加入到 UE的准入列表;
其中, 具体描述可以参见第二实施例;
步骤 480, 接入点 AP设备根据更新后的准入列表对 UE执行准入; 其中, 具体描述可以参见第二实施例。
本发明实施例提供的技术方案, 通过增加设定第一预设次数, 使统计 值建立在更多的统计次数基础上, 使统计的结果更准确。 另外, 通过设定 第二预设次数, 增加被确定为信号最强的 CSG小区和其他小区信号强度的 差距, 以保证确定为信号最强的 CSG小区的信号远远强于其他被搜索到的 CSG小区。 实施例四
本发明第四实施例涉及一种准入方法。 图 5 为本发明第三实施例流程 示意图。 如图 5所示, 本发明第四实施例的准入方法包括以下步骤:
步骤 510, 将 UE加入 CSG小区的准入用户列表;
CSG小区所对应的接入点 AP设备将 UE标识加入到该 CSG小区的准 入用户列表, 形成 CSG小区的新的准入列表;
可以理解的是, 该接入点 AP设备将 UE标识加入到该 CSG小区的准 入用户列表可以是根据运营商的指令而进行操作的。 在接入点 AP设备将 UE加入到 CSG小区的准入用户列表之后, 可以形成该 CSG小区的新的准 入列表。 另外, 该接入点 AP设备可以对新的准入列表进行保存。 比如, 原 来某个 CSG小区(比如 cell 1 )只允许 UE 1和 UE 2的接入, 而 AP设备可 以增加 UE 3到该小区的准入列表中,形成新的包含 UE 1至 UE 3的准入列 表, 并予以保存。
AP设备在以后判断某个向该 CSG小区发起准入请求的 UE能否准入 时, 可以采用更新后的准入列表。 这意味着, 在此后如果 UE向该 CSG小 区发起准入请求, 该 CSG会根据协议同意该 UE的准入请求;
步骤 520, UE向修改为混合准入模式的 CSG小区发起驻留请求,修改 为混合准入模式的 CSG小区为增加了 UE的准入列表所对应的 CSG小区; 在 CSG小区对应的接入点 AP设备将 UE设备标识加入到该 CSG小区 的准入用户列表之后,接入点 AP设备可以将该 CSG小区从常规的封闭 CSG 小区修改为混合模式的 CSG小区, 即,使得该 CSG小区可以允许在其自身 的准入列表中已经存在的 UE的驻留请求,尽管该 UE的准入小区列表中还 没有该 CSG小区。但是该 CSG小区会拒绝在其自身的准入列表中不存在的 UE的驻留请求。
假设, 原来该 CSG小区 cell 1的准入用户列表中有 UE1和 UE2, 该 UE1和 UE2的准入小区列表中也包含该 cell 1。 当该 cell 1小区的准入用户 列表中增加了 UE3, 形成了新的包含 UE1至 UE3的准入列表。 该 cell 1通 过接入点 AP设备修改为混合模式, 则当该 UE3向 cell 1发起驻留请求时, 该 cell 1会允许该 UE3的驻留请求。 但是, 如果不在该 cell 1准入用户列表 中的 UE4向该 cell 1发起驻留请求, 该 cell 1会拒绝该 UE4的驻留请求。
步骤 530, UE确定该修改为混合准入模式的 CSG小区为自身可接入的 小区;
UE在步骤 520中向修改为混合准入模式的 CSG小区发起驻留请求, 若 UE成功驻留在 CSG小区,即,如果该 CSG小区允许该 UE的驻留请求, 则 UE确定修改为混合准入模式的 CSG小区为自身可接入的小区; 若 UE 不能成功驻留在该 CSG小区,即,如果该 CSG小区拒绝该 UE的驻留请求, 则 UE确定修改为混合准入模式的 CSG小区不是自身可接入的小区。
具体而言,在该 CSG小区被修改为混合模式的 CSG小区之后的一段时 间内, 除了该 UE向该 CSG小区发起驻留请求之外, 也可能有该 CSG小区 的准入用户列表中不包含的 UE向该小区发起驻留请求。
当该 CSG小区列表中不包含的 UE向该小区发起驻留请求,该 CSG小 区会拒绝该不在其列表中的 UE发起的驻留请求。 当该增加在 CSG小区准 入列表中的 UE (比如 UE 3 )向该 CSG小区发起驻留请求, 该 CSG小区则 会允许该 UE的驻留请求。
当 UE3向修改为混合模式的 cell 1发起驻留请求, cell 1会允许 UE3 的驻留请求, 这说明该修改为混合模式的 cell 1为该 UE3可以接入的小区; 当 UE4向修改为混合模式的 cell 1发起驻留请求, cell 1会拒绝 UE4的驻留 请求, 这说明该修改为混合模式的 cell 1不是该 UE4可以接入的小区; 因此, 如果该 UE能成功驻留在 CSG小区, 则说明该修改为混合准入 模式的 CSG小区是该 UE可以接入的小区, 并进行后续步骤 540。
步骤 540, UE将该 CSG小区加入到 UE的准入小区列表;
UE将该允许 UE接入的 CSG小区的标识加入到 UE的准入列表,从而 更新了 UE的准入小区列表。 这样在今后 UE进行 CSG小区搜索时, 如果 再搜索到该 CSG小区,则可以立即辨认出该 CSG小区是 UE的准入小区列 表中的 CSG小区, 可以发起准入。
当 UE3向修改为混合模式的 cell 1发起驻留请求, cell 1允许了 UE3 的驻留请求, UE3将 cell 1加入到自身的准入小区列表中。 假设 UE3原先 的准入小区列表中包括 cell 2和 cell 3, 则现在加入 cell 1, 形成从 cell 1至 cell 3的准入小区列表。
步骤 550, 接入点 AP设备根据更新后的准入列表对 UE执行准入; 在 UE形成了更新的准入小区列表之后,由于 UE的列表已经更新, UE 的准入小区列表中包含该 CSG小区,而该 CSG小区也已将该 UE加入列表, 当该 UE向该 CSG小区发起准入,则该小区接入点 AP设备允许 UE的准入 请求。
可见, 本发明实施例提供的技术方案, 在网络侧设备在某个 CSG小区 的准入用户列表中增加 UE的情况下, 通过将该 CSG小区修改为混合准入 模式, UE尝试驻留机制, 使得 UE侧及时更新准入小区列表, 以保持和网 络侧更新后的准入信息的一致性, 提高了 CSG功能的可用性和完善性。
可以理解的是, 在本发明的步骤 520中, 将该 CSG小区从常规的封闭 CSG模式修改为混合模式, 是为了让已经在 CSG小区的准入用户列表中、 而 UE自身的列表中还没有该 CSG的 UE在发起驻留请求时, 该 CSG小区 能允许该 UE的驻留请求。 因此, 当该 UE已经成功驻留在该 CSG小区, 该 CSG小区可以修改回常规的封闭 CSG模式。
本发明实施例提供的技术方案在 UE 确定该修改为混合准入模式的 CSG小区为自身可接入的小区之后将该小区的模式修改回封闭模式, 使得 在 UE驻留在该小区之后, 减少因其他 UE尝试驻留而产生的网络侧和 UE 侧耗电。 实施例五

1、 CSG小区对应的 AP设备获取 UE的当前服务小区;
2、 CSG小区对应的 AP设备将该 CSG小区把 UE加入准入列表的第一 消息发送给 UE的当前服务小区。
本步骤中, 根据 UE的当前服务小区为 CSG小区或者为非 CSG小区, 分成两种方式: 方式一, 如果 UE的当前服务小区为非 CSG小区, 则该第 一消息可以由该 CSG小区对应的 AP设备通过网管发送到该 UE的当前服 务小区。 方式二, 如果 UE的当前服务小区为 CSG小区, 则该 CSG小区对 应的 AP设备可以将 该第一消息直接发送给该 UE的当前服务小区。
3、该 UE的当前服务小区将该第一消息通过空中接口以 OTA (Over The Air, 一项基于短消息的机制)方式发送给该 UE。
4、 UE确认该 CSG小区为自身可接入的小区;
步骤 630, UE将该 CSG小区加入到 UE的准入列表;
其中, 具体描述可以参见第二实施例;

本发明实施例提供的技术方案, 在网络侧设备在某个 CSG小区的准入 用户列表中增加 UE的情况下,通过 UE收到自身当前服务小区发送的第一 消息, 确定该 CSG小区为自身可接入的小区, 使得 UE侧及时更新准入小 区列表, 以保持和网络侧更新后的准入信息的一致性, 提高了 CSG功能的 可用性和完善性。 实施例六
本发明第六实施例涉及一种准入方法。 图 7为本发明第六实施例流程 示意图。 如图 7所示, 本发明第六实施例的准入方法包括以下步骤: 步骤 710, CSG小区所对应的接入点 AP设备将 UE标识加入到该 CSG 小区的准入用户列表, 形成 CSG小区的新的准入列表;
其中, 具体描述可以参见第五实施例;
步骤 720, UE收到自身当前服务小区发送的携带更新的 UE的准入小 区列表的第二消息, 更新的准入列表中包含该 CSG小区的标识;
具体而言, 本步骤可以包括以下子步骤:
1、 CSG小区对应的 AP设备获取该 UE的当前服务小区;
2、 CSG小区对应的 AP设备将携带该更新的 UE的准入小区列表的第 二消息发送给该 UE的当前服务小区;
在本步骤中, 第二消息可以根据 UE的当前服务小区是否是 CSG小区 而通过不同的发送途径来发送。 具体可参照本发明实施例五。
3、 UE的当前服务小区将该第二消息发送给该 UE。
从 UE的角度而言,通过上述步骤就获取了自身当前服务小区所发送的 第二消息。
步骤 730, UE将 CSG小区加入到 UE的准入列表;
其中, 具体而言, UE 可以在接收到该更新的准入列表之后, 直接在 UE上进行保存, 从而实现将该 CSG小区加入到 UE的准入列表的步骤。
步骤 740, 接入点 AP设备根据更新后的准入列表对 UE执行准入; 其中, 具体描述可以参见第二实施例。
本发明实施例提供的技术方案, 在网络侧设备在某个 CSG小区的准入 用户列表中增加 UE的情况下,通过 UE收到自身当前服务小区发送的第二 消息, 确定该 CSG小区为自身可接入的小区, 使得 UE侧及时更新准入小 区列表, 以保持和网络侧更新后的准入信息的一致性, 提高了 CSG功能的 可用性和完善性。 实施例七

本发明第十一实施例涉及一种准入方法。 图 12为本发明第十一实施例 流程示意图。如图 12所示,本发明第十一实施例的准入方法包括以下步骤: 步骤 1201 : UE进行 CSG小区搜索;
一般而言, 有 CSG功能的 UE会进行周期性的 CSG小区搜索; 步骤 1202: UE确定所搜索到的信号最强的 CSG小区;
UE对所搜索到的 CSG小区的信号强度进行比较, 找出所有搜索到的
CSG小区中信号最强的 CSG小区。 其中, 具体方式可以参考实施例三的步 骤 440;
步骤 1203: UE向该信号最强的 CSG小区发起驻留请求;
可以理解的是, UE向该信号最强的 CSG小区发起驻留在该 CSG小区 的请求;
