接入设备在本发明中可以是接入网元、 接入网关、 或者移动性管理网元 或 non-3GPP GW, 控制网元可以是接入网元或 CSG区域下的接入网元。
本发明实施例所提供的方法， 当请求接入的用户设备所要求的资源不能 满足时， 如果接入设备确定请求接入的用户设备的优先级高于已经接入的用 户设备， 则允许请求接入的用户设备接入， 并删除已经接入的优先级较低的 用户设备， 增加了用户体验。
在本发明实施例中， 所述资源可以是控制网元中允许接入的用户设备数， 也可以是控制网元所能提供的最大带宽等等， 下面结合具体实施例作详细的 描述。 参见附图 2b， 本发明实施例提供了一种控制用户设备接入的方法， 包括:
201. 已经接入控制网元中的用户设备数与请求接入的用户设备数之和 超过允许接入的用户设备数， 且区分用户设备优先级时， 接入设备确定控制 网元中已经接入的用户设备的优先级与请求接入的用户设备的优先级之间的
202、 请求接入的用户设备的优先级高于一个已经接入的用户设备的优先 级， 则允许所述请求接入的用户设备的接入。

接入设备在本发明中可以是接入网元、 接入网关、 或者移动性管理网元 或 non-3GPP GW, 控制网元可以是接入网元或 CSG区域。
需要说明的是， 在本发明实施例中控制网元中的资源是控制网元中允许 接入的用户设备数， 接入网元可以为家庭无线接入点 （如 HNB或者 HeNB或者 Home non-3GPP WAP)或者为具有 CSG功能的无线接入点（如 NodeB或者 eNodeB 或者 non-3GPP P) ; 接入网关可以为家庭无线接入点网关， 如 HNB GW、 HeNB GW或者 Home non-3GPP WAP GW; 移动性管理网元可以为 MME或者 SGSN。
接入设备获得控制网元中准入的用户设备数以及用户设备的优先级， 包 括：
家庭接入管理服务器、 归属用户服务器或者运营商的后台系统将控制网 元中准入的用户设备数以及用户设备的优先级发送给接入网元、 接入网关或 移动性管理网元或 non-3GPP GW; 或者
家庭接入管理服务器、 归属用户服务器或者运营商的后台系统将控制网 元中准入的用户设备数以及用户设备的优先级发送给接入网元或接入网关， 接入网元或接入网关将该准入的用户设备数和用户设备的优先级发送给移动 性管理网元或 non-3GPP GW。
其中运营商的后台系统为运营商的运营支撑系统 （Operation Support System ， 0SS )或者电信业务运营支撑系统 (Business and Operation Support System ， BOSS ) 或者操作维护中心 (Operation and Maintenance Center, OMC) 等， 主要是运营商进行操作维护、 配置管理等功能的运营支撑系统， 其 一般通过操作维护接口和接入网元、 接入网关或移动性管理网元或 non-3GPP GW相连， 对接入网元、 接入网关或移动性管理网元或 non-3GPP GW进行配置 管理、 操作维护等。
本发明中， 当已经接入控制网元中的用户设备数与请求接入的用户设备 数之和超过允许接入的用户设备数， 且用户设备区分优先级时， 允许请求接 入的用户设备接入就必须删除一个已经接入的优先级较低的用户设备， 或者 将该用户设备切换或迁移到允许接入的小区， 既能实现差异化的服务， 又增 加了用户体验， 同时在一些场景下也不中断从控制网元中删除的用户设备正 在使用的业务。 参见附图 3， 当接入设备是接入网元时， 本发明实施例提供了一种控制用 户设备接入的方法， 接入网元允许请求接入的用户设备接入， 将一个已经接 入的优先级较低的用户设备分离出去， 包括：
301. 接入网元获得允许接入控制网元中的用户设备数
接入网元获得控制网元允许接入的用户设备数， 控制网元可以是接入网 元或者 CSG 区域， 接入网元也可以获得允许接入的用户设备的优先级， 如： 允许接入的用户的身份： 成员、 朋友、 客人等； 这些信息可以配置在家庭接 入管理服务器中、 归属用户服务器或者运营商的后台系统， 如运营支撑系统 (Operation Support System ， OSS ) 或者电信业务运营支撑系统 （Business and Operation Support System ， BOSS ) 等， 由家庭接入管理服务器、 归属 用户服务器或者运营商的后台系统发送给接入网元， 接入网元可以为家庭无 线接入点， 如 HNB或者 HeNB或者 Home non-3GPP WAP, 或者为具有 CSG功能 的无线接入点， 如 NodeB、 eNodeB或者 non-3GPP WAP;
302. 用户设备接入到接入网元
用户设备发送接入请求消息到接入网元；
需要说明的是， 在本步骤中， 用户设备是请求接入到接入网元， 用户设 备接入到接入网元还包括所述用户设备切换到所述接入网元的场景， 这种场 景下接入网元接收到移动性管理网元或者 non-3GPP GW发送的切换请求消息 后， 转到步骤 303进行处理； 后面所有实施例均做类似的处理。
303. 当控制网元中已经接入的用户设备数加上请求接入的用户设备数 超过允许接入的用户设备数， 且用户设备不区分优先级时， 拒绝请求接入的 用户设备接入
接入网元判断控制网元中已经接入的用户设备数与请求接入的用户设备 数之和是否超过允许接入的用户设备数， 如果还没有超过， 则接入网元允许 用户设备接入； 如果超过， 则接入网元拒绝用户设备的接入， 同时返回拒绝 接入消息到用户设备， 消息中可以携带有指示信息指示用户设备接入拒绝是 由于用户设备接入数超过准入的用户设备数导致的， 所述用户设备的接入数 即接入控制网元的用户设备数与请求接入的用户设备数之和， 如消息中携带 Cause 原因值 "Access number exceed CSG Al lowed Access Number "指示 UE用户数接入受限。 根据这个指示信息， 用户设备可启动一个定时器， 在这 个定时器规定的时间内， 用户设备将不再选择这个接入网元或者这个 CSG 区 域来接入。 用户设备收到这个消息后选择一个允许接入的小区来接入， 如其 它允许接入的 CSG小区， 即用户的 Al lowed CSG l ist中除当前接入的 CSG ID 以外的其它 CSG ID所对应的小区， 或者非 CSG小区， 如宏 macro小区等， 用 户设备无需将当前的 CSG ID从自己的准入 CSG列表中删除；
需要说明的是， 超过定时器规定的时间， 用户设备可以再选择这个接入 网元或者这个 CSG区域来接入。
其中， 拒绝接入消息中携带的指示信息也可以指示用户设备， 所述拒绝 接入是由于控制网元中的资源不足导致的， 如消息中携带 Cause 原因值为 "Resources insufficient ", 后面所有实施例均做类似的处理。
需要说明的是， 本步骤中描述的允许接入的用户设备数即控制网元中允 许接入的用户设备数。 304. 当用户设备区分优先级， 且存在已经接入的用户设备的优先级低于 请求接入的用户设备的优先级时， 接入网元发送释放请求消息给移动性管理 网元或者 non-3GPP GW。
如果控制网元中准入的用户设备区分用户优先级， 则要判断控制网元中 已经接入的用户设备是否有优先级低于请求接入的用户设备， 如客人的优先 级低于朋友， 朋友的优先级低于成员； 如果没有， 则拒绝请求接入的用户设 备接入； 如果有， 接入网元则允许请求接入的用户设备接入， 同时接入网元 在其所接入的用户设备中分离一个低优先级的用户设备。 接入网元发送一个 释放请求消息到移动性管理网元或者 non-3GPP网关， 消息中携带指示信息指 示移动性管理网元或者 non-3GPP网关这个释放请求是由于用户设备接入数超 过准入的用户设备数导致的， 如消息中携带 Cause原因值为 "Access number exceed CSG Al lowed Access Number "指示用户设备接入数受限。对于 E-UTRAN 网络， 释放请求消息为用户设备上下文释放请求 （UE Context Release Request ) 消息； 对于 GERAN/UTRAN网络， 释放请求消息为 lu释放请求 （lu Release Request ) 消息； 对于 non_3GPP 网络， 释放请求消息为资源释放请 求 （Resource Release Request ) 消息。 对于 E-UTRAN 网络， 移动性管理网 元为 MME; 对于 GERAN/UTRAN网络， 移动性管理网元为 SGSN; 对于 WLAN网络， non-3GPP GW为 EPDG; 对于 Wimax网络， non_3GPP GW为 ASN GW; 对于 CDMA 网络， non-3GPP GW为 AGW; 对于 HRPD网络， non_3GPP GW为 HSGW;
需要说明的是释放请求消息中携带的指示信息也可以指示移动性管理网 元或者 non-3GPP网关这个释放请求是由于控制网元中的资源不足导致的， 如 消息中携带 Cause原因值为 "Resources insufficient 'Ό 后面所有实施例的 处理同样。
同时， 接入设备可以先将控制网元中已经接入的用户设备进行排序， 将 优先级最低的用户设备与请求接入的用户设备进行比较， 如果请求接入的用 户设备的优先级高于已经接入的优先级最低的用户设备， 则允许请求接入的 用户设备接入， 并删除已经接入的优先级最低的用户设备， 否则不允许请求 接入的用户设备接入。
如果请求接入的用户设备不止一个时， 控制网元中已经接入的用户设备 数等于允许接入的用户设备数时， 将第一个请求接入的用户设备与已经接入 的用户设备进行比较， 如果第一个请求接入的用户设备的优先级高于一个已 经接入的用户设备， 则允许第一个请求接入的用户设备接入， 删除优先级较 低的用户设备； 然后比较第二个请求接入的用户设备， 依此类推……
如果请求接入的用户设备不止一个， 控制网元中还能继续接入用户设备， 如： 请求接入的用户设备是 4个， 控制网元中还能接入 2个， 则先任意接入 2 个请求接入的用户设备， 然后比较剩余的 2个用户设备与控制网元中已经接 入的用户设备的优先级的关系， 后面所有实施例也作类似的处理。
需要说明的是： 本专利中不限定允许请求接入的用户设备接入和接入网 元在其所接入的用户设备中分离低优先级的用户设备的先后处理顺序。 如， 接入网元可以先允许请求接入的用户设备接入， 后再在其所接入的用户设备 中分离低优先级的用户设备； 或者， 接入网元可以先在其所接入的用户设备 中分离低优先级的用户设备， 后再允许请求接入的用户设备接入； 或者， 接 入网元可以先在其所接入的用户设备中分离低优先级的用户设备， 拒绝请求 接入的用户设备接入， 在低优先级的用户设备分离后再收到用户设备请求接 入时允许请求的用户设备接入。
305. 移动性管理网元或者 non-3GPP GW发送分离请求（Detach Request ) 到用户设备
移动性管理网元或者 non-3GPP GW收到上述释放请求消息后， 分离用户 设备， 具体过程为： 发送分离请求到优先权较低的用户设备， 消息中可以携 带指示信息指示用户设备分离请求是由于用户设备接入数超过准入的用户设 备数导致的，如消息中携带 Cause 原因值为 " Access number exceed CSG Al lowed Access Number "指示用户设备接入数受限。 根据这个指示信息， 用 户设备可以选择启动一个定时器， 在这个定时器的时间内， 用户设备将不再 选择这个接入网元或者这个 CSG区域来接入， 用户设备无需将当前的 CSG ID 从自己的准入 CSG列表中删除；
需要说明的是分离请求消息中携带的指示信息也可以指示用户设备分离 请求是由于控制网元中资源不足导致的， 如消息中携带 Cause 原因值为 "Resources insufficient ", 被删除的用户设备收到所述指示信息后， 启动 一个定时器， 在所述定时器规定的时间内可以不再选择这个接入网元或者这 个 CSG区域来接入， 超过定时器规定的时间， 则该被删除的用户设备可以再 选择这个接入网元或者这个 CSG 区域来接入， 后面所有实施例也作类似的处 理。
306. 用户设备回分离接受 （Detach Accept ) 消息给移动性管理网元或 者 3GPP GW
优先级较低的用户设备回分离接受信息到移动性管理网元或者 non-3GPP GW, 该用户设备可以选择非 CSG小区或者其它允许接入的 CSG小区来接入。
307. 接入网元释放资源
移动性管理网元或者 non-3GPP GW通知接入网元释放资源。 对于 E-UTRAN 网络， MME发送用户设备上下文释放命令 （UE Context Release Command) 消息到接入网元；对于 GERAN/UTRAN网络， SGSN发送 Iu释放命令（Iu Release Command) 消息到接入网元； 对于 non_3GPP网络， non_3GPP GW发送资源释 放命令 （Resource Release Command ) 消息到接入网元。 接入网元释放资源 后，回释放完成（Release Complete )消息到移动性管理网元或者 non_3GPP GW 本发明实施例中， 接入网元在分离优先级较低的用户设备时， 发送释放 请求消息给移动性管理网元或者 non-3GPP GW;移动性管理网元或者 non_3GPP GW发送分离请求到用户设备； 用户设备回分离接受消息给移动性管理网元或 者 non-3GPP GW; 移动性管理网元或者 non_3GPP GW通知接入网元释放资源， 完成对优先级较低的用户设备的分离， 同时允许优先级较高的用户设备的接 入。 从而实现差异化的服务处理， 增加用户的体验。
需要说明的是， 在本发明实施例中， 接入网元也可以作为控制网元， 或 者 CSG区域作为控制网元； 接入网关是可选网元， 如果存在接入网关， 则接 入网元通过接入网关与其它网元进行交互， 如果没有接入网关， 则接入网元 直接与其它网元进行交互。
在本发明各实施例中， 所述 CSG区域作为控制网元是指逻辑上的功能实 体， 当一个接入网元管理一个 CSG区域时， 该接入网元作为 CSG区域作为控 制网元， 如果多个接入网元共同管理一个 CSG 区域时， 多个接入网元共同作 为 CSG区域作为控制网元， 当一个接入网元管理多个 CSG区域时， 那个该接 入网元中管理某一个 CSG区域的功能部分可以作为 CSG区域作为控制网元。
可选地， 在步骤 304中， 接入网元也可以发送释放请求 Release Request 消息到已经接入的优先级较低的用户设备而不是发送释放请求消息到移动性 管理网元或者 non-3GPP GW, 消息中携带指示信息指示这个释放请求是由于用 户设备接入数超过准入的用户设备数导致的， 或者是由于控制网元中资源不 足导致的，如消息中携带 Cause原因值为" Access number exceed CSG Al lowed Access Number "指示用户设备接入数受限或者 Cause 原因值为 "Resources Insufficient "指示控制网元中资源不足。 则后续步骤为：
步骤 305 中， 已经接入的优先级较低的用户设备收到释放请求消息后发 送分离请求 Detach Request消息到移动性管理网元或者 non_3GPP GW。
步骤 306中， 移动性管理网元或者 non-3GPP GW向已经接入的优先级较 低的用户设备回复分离接受 Detach Accept消息。
可选地， 所述已经接入的优先级较低的用户设备可以选择启动一个定时 器， 在这个定时器规定的时间内， 所述已经接入的优先级较低的用户设备将 不再选择这个接入网元或者这个 CSG区域来接入， 所述已经接入的优先级较 低的用户设备无需将当前的 CSG ID从自己的准入 CSG列表中删除； 所述已经 接入的优先级较低的用户设备可以选择其他允许接入的小区 （如 non-CSG小 区（如 macro (宏）小区）或者其它允许接入的 CSG小区（即 Al lowed CSG Li st 中除当前使用的 CSG ID外的其它 CSG ID相应的 CSG小区）） 来接入。 所述已 经接入的优先级较低的用户设备发起附着 （Attach ) 流程， 通过选择的小区 注册到运营商的移动网络。
步骤 307中， 接入网元释放资源。
本发明实施例所提供的方法也能应用到其它的资源不足时的处理， 如接 入网元收到一个用户设备的业务建立请求（如，对于 E-UTRAN网络来说， HeNB 从 MME中收到 Bearer Setup Request (承载建立请求） 消息请求建立一个承 载； 对于 GERAN/UTRAN网络， HNB从 SGSN中收到 RAB Assignment Request (无 线接入承载分配请求） 消息请求建立一个承载） 时， 接入网元确定接入网元 或者 CSG 区域内的资源不能满足请求接入的用户设备的业务需要 （如接入网 元的可用带宽不能满足请求建立的承载需要的带宽） 时， 接入网元判断接入 网元或者 CSG区域内中已经接入的用户设备是否有优先级低于请求业务建立 的用户设备， 如控制网元的成员列表内的客人的优先级低于控制网元的成员 列表内的朋友、 控制网元的成员列表内的朋友的优先级低于控制网元的成员 列表内的成员 （控制网元的成员列表内的用户设备的优先级的获取参见前面 的描述）， 或者非控制网元用户 （gp， 不在控制网元的成员列表内的用户， 如 不在 CSG 的成员列表内的用户） 优先级低于控制网元用户 （这时， 控制网元 的成员列表内的用户设备可能没有优先级， 则家庭接入管理服务器、 归属用 户服务器或者运营商的后台系统只需将控制网元的成员列表信息发给接入网 元） 等； 如果没有， 则拒绝请求建立的业务； 如果有， 接入网元则允许请求 建立的业务建立， 同时接入网元在接入网元或者或者 CSG 区域内所接入的用 户设备中分离低优先级的用户设备 （分离的用户设备可能不只一个， 如请求 接入的用户设备的业务建立请求要求 3M带宽， 接入网元可用的带宽只有 1M, 每个 non-CSG用户设备使用的带宽也只有 1M, 这个时候接入网元就需要分离 两个 non-CSG用户设备， 后面所有实施例也作类似的处理）， 分离低优先级的 用户设备的具体过程参照本发明实施例的描述。
需要说明的是： 本专利中不限定接入网元允许请求建立的业务建立和接 入网元在接入网元或者 CSG 区域内所接入的用户设备中分离低优先级的用户 设备的先后处理顺序。 如， 接入网元可以先允许请求建立的业务建立， 后再 在接入网元或者 CSG 区域内所接入的用户设备中分离低优先级的用户设备； 或者， 接入网元可以先在接入网元或者 CSG区域内所接入的用户设备中分离 低优先级的用户设备， 后再允许请求建立的业务建立； 或者， 接入网元可以 先在接入网元或者 CSG区域内所接入的用户设备中分离低优先级的用户设备， 拒绝请求建立的业务建立， 在低优先级的用户设备分离后再收到用户设备的 业务建立请求时允许建立。
参见附图 4， 接入设备为接入网元时， 本发明实施例提供了一种控制用户 设备接入的方法， 接入网元允许请求接入的用户设备接入的同时， 发起切换 或者重定位流程， 将已经接入的优先级较低的用户设备切换到其它小区， 具 体包括：
401. 接入网元获得控制网元允许接入的用户设备数， 具体过程参照步骤
301 ;
402. 用户设备接入接入网元， 具体过程参照步骤 302 ;
403. 当控制网元中已经接入的用户设备数加上请求接入的用户设备数 超过允许接入的用户设备数， 且用户设备不区分优先级时， 拒绝请求接入的 用户设备接入， 具体过程参照步骤 303 ;
404. 当用户设备区分优先级， 且存在已经接入的用户设备的优先级低于 请求接入的用户设备的优先级时， 接入网元发送切换请求消息给移动性管理 网元或者 non-3GPP GW
如果控制网元中准入的用户设备区分用户优先级， 则要判断控制网元中 已经接入的用户设备是否有优先级低于请求接入的用户设备， 如果没有， 则 接入网元拒绝请求接入的用户设备接入； 如果有， 接入网元则允许请求接入 的用户设备接入， 同时接入网元选择允许接入的小区， 即非 CSG小区或者其 他允许接入的 CSG小区， 将这个小区作为目标小区， 并且接入网元发起切换 (Handover或者 Handoff ) 或者重定位 （Relocation) 程序， 将接入网元中 的一个低优先级的用户设备切换到目标小区， 接入网元发送切换要求 (Handover Required ) 消息到移动性管理网元或者 non_3GPP GW。
需要说明的是： 本专利中不限定允许请求接入的用户设备接入和接入网 元将接入网元中的低优先级的用户设备切换到目标小区的先后处理顺序。 如， 接入网元可以先允许请求接入的用户设备接入， 后再将接入网元中的低优先 级的用户设备切换到目标小区； 或者， 接入网元可以先将接入网元中的低优 先级的用户设备切换到目标小区， 后再允许请求接入的用户设备接入； 或者， 接入网元可以先将接入网元中的低优先级的用户设备切换到目标小区， 拒绝 请求接入的用户设备接入， 在低优先级的用户设备切换到目标小区后再收到 用户设备请求接入时允许请求的用户设备接入。
405. 移动性管理网元或者 non-3GPP GW回切换命令或者切换拒绝到接入 网元
移动性管理网元或者 non-3GPP GW 回切换命令 （Handover Command ) 或 者切换拒绝 （Handover Reject ) 消息到接入网元， 切换拒绝消息表示接入网 元发起的切换流程失败， 用户设备不能切换到目标小区。
406. 接入网元发送切换命令给用户设备
如果接入网元收到切换命令消息， 则接入网元发送切换命令消息到用户 设备， 命令用户设备切换到目标小区。 切换命令消息中可以携带指示信息指 示用户设备切换是由于用户设备接入数超过准入的用户设备数导致的， 如消 息中携带 Cause原因值 "Access number exceed CSG Al lowed Access Number " 指示 UE用户数接入受限。根据这个指示信息，用户设备可以启动一个定时器， 在这个定时器的时间内， 用户设备将不再选择这个接入网元或者这个 CSG 区 域来接入， 用户设备无需将当前的 CSG ID从自己的准入 CSG列表中删除。 需要说明的是切换命令消息中携带的指示信息也可以指示用户设备切换 是由于控制网元中资源不足导致的，如消息中携带 Cause原因值为" Resources insufficient ", 后面的所有实施例均做类似处理。
407. 用户设备切换到目标小区
用户设备接到接入网元的切换命令后， 执行切换到目标小区的流程， 切 换到目标小区；
408. 如果步骤 404中接入网元不能选择一个允许接入的小区作为目标小 区发起切换流程， 或者步骤 405 中接入网元收到切换拒绝的消息， 则接入网 元发起释放流程， 执行分离用户设备的程序， 将优先级较低的用户设备分离， 具体参照步骤 304至步骤 307。

需要说明的是， 在本发明实施例中， 接入网元也可以作为控制网元， 或 者 CSG区域作为控制网元； 接入网关是可选网元， 如果存在接入网关， 则接 入网元通过接入网关与其它网元进行交互， 如果没有接入网关， 则接入网元 直接与其它网元进行交互。
本发明实施例所提供的方法也能应用到其它的资源不足时的处理， 如接 入网元收到一个用户设备的业务建立请求时，接入网元确定接入网元或者 CSG 区域内的资源不能满足请求的业务需要时， 接入网元判断接入网元或者 CSG 区域中已经接入的用户设备是否有优先级低于请求业务建立的用户设备； 如 果没有， 则拒绝请求建立的业务； 如果有， 接入网元则允许请求建立的业务 建立， 同时接入网元发起切换 （Handover 或者 Handof f ) 或者重定位 (Relocation) 程序， 将接入网元或者 CSG区域中的低优先级的用户设备切 换到一个允许接入的小区， 切换或者重定位的处理参照本发明实施例。

需要说明的是， 在本发明实施例中， 接入设备是接入网关， 控制网元是 接入网元或者 CSG区域。
本发明实施例所提供的方法也能应用到其它的资源不足时的处理， 如接 入网关收到一个用户设备的业务建立请求时， 接入网关确定所述用户设备所 接入的接入网元或者 CSG 区域的资源不能满足所述用户设备的业务需要时， 接入网关判断接入网元或者 CSG 区域中已经接入的用户设备是否有优先级低 于请求业务建立的用户设备； 如果没有， 则拒绝请求建立的业务； 如果有， 接入网关则允许请求建立的业务建立， 同时接入网关通知接入网元或者 CSG 区域中的低优先级的用户设备发起更新流程， 将所述低优先级的用户设别迁 移到其他允许接入的小区， 具体参照本发明实施例的描述。
需要说明的是： 本专利中不限定允许请求建立的业务建立和接入网关通 知低优先级的用户设备发起位置更新流程的先后处理顺序。 如， 接入网关可 以先允许请求建立的业务建立， 后再通知低优先级的用户设备发起位置更新 流程； 或者， 接入网关可以先通知低优先级的用户设备发起位置更新流程， 后再允许请求建立的业务建立； 或者， 接入网关可以先通知低优先级的用户 设备发起位置更新流程， 拒绝请求建立的业务建立， 在低优先级的用户设备 更新到目标小区后再收到用户设备的业务建立请求时允许建立。 如图 9所示， 接入设备是移动性管理网元或者 non-3GPP GW时， 本发明 实施例提供了一种控制用户设备接入的方法， 移动性管理网元或者 non-3GPP GW在允许请求接入的用户设备接入的同时， 将一个已经接入的优先级较低的 用户设备分离出去， 具体包括：
901. 移动性管理网元或者 non-3GPP GW获得控制网元允许接入的用户设 备数
移动性管理网元或者 non-3GPP GW获得控制网元允许接入的用户设备数， 移动性管理网元或者 non-3GPP GW也可以获得允许接入的用户设备的优先级， 如：允许接入的用户的身份：成员、朋友、客人等；这些信息可以配置在匪 S 、 HSS或者运营商的后台系统中， 由匪 S、 HSS或者运营商的后台系统发送给移 动性管理网元或者 non-3GPP GW。 这些信息也可以由接入网关或者接入网元上 报给移动性管理网元或者 non-3GPP GW, 如接入网元或者接入网关发送设置请 求 （Setup Request ) 消息给移动性管理网元或者 non_3GPP GW, 这个请求消 息中携带接入网元或者 CSG 区域中准入的用户设备数， 请求消息中也可以携 带接入网元或者 CSG 区域中准入的用户设备的优先级；
902. 用户设备接入移动性管理网元或者 non-3GPP GW
用户设备通过接入网元接入到移动性管理网元或者 non-3GPP GW, 用户设 备发送接入请求消息到移动性管理网元或者 non-3GPP GW;
需要说明的是， 在本步骤中， 用户设备通过接入网元接入到移动性管理 网元或者 non-3GPP GW, 用户设备接入到移动性管理网元或者 non_3GPP GW还 包括这个用户设备切换到这个移动性管理网元或者 non-3GPP GW的场景， 这 种场景下移动性管理网元或者 non-3GPP GW收到切换请求消息， 后面所有实 施例的处理同样。
903. 当控制网元中已经接入的用户设备数加上请求接入的用户设备数 超过允许接入的用户设备数， 且用户设备不区分优先级时， 拒绝请求接入的 用户设备接入
移动性管理网元或者 non-3GPP GW判断控制网元中已经接入的用户设备 数与请求接入的用户设备数之和是否超过控制网元允许接入的用户设备数， 如果没有超过， 则允许请求接入的用户设备接入， 如果超过， 则拒绝请求接 入的用户设备接入， 并返回拒绝接入消息到该用户设备， 消息中可以携带指 示信息指示该用户设备接入拒绝是由于用户设备数超过准入的用户设备数导 致的， 如消息中携带 Cause 原因值 "Access number exceed CSG Allowed Access Number"指示用户数接入受限。 根据这个指示消息， 该用户设备可以 选择启动一个定时器， 在该定时器规定的时间内不再选择当前这个接入网元 或者这个 CSG区域来接入， 该用户设备收到这个消息后选择允许接入的小区 来接入。该用户设备无需将当前的 CSG ID地址从自己的准入 CSG列表中删除。
为了实现对接入到控制网元中的用户设备接入数的监控， 移动性管理网 元或者 non-3GPP GW需要获得接入的接入网元的标识或者接入网元的 CSG ID 信息， 接入网元可以在建立 （Setup) 流程中将接入网元的标识或者接入网元 的 CSG ID信息发送给移动性管理网元或者 non-3GPP GW, 或者接入网元或者 接入网关在发送非接入层 （Non-Access Stratum, NAS) 消息到移动性管理网 元或者 non-3GPP GW时， 发送用户设备接入的接入网元标识或者 CSG标识， 即接入网元或者接入网关在初始用户设备消息 （Initial UE Message ) 中携 带接入网元的标识或者 CSG标识。
904. 当用户设备区分优先级， 且存在已经接入的用户设备的优先级低于 请求接入的用户设备的优先级时， 移动性管理网元或者 non-3GPP GW发送分 离请求消息给用户设备
如果控制网元中准入的用户设备区分用户优先级， 则移动性管理网元或 者 non-3GPP GW判断控制网元中已经接入的用户设备是否存在优先级低于正 在请求的用户设备的优先级， 如果不存在， 则拒绝请求接入的用户设备接入; 如果存在， 则允许请求的用户设备接入， 同时分离一个优先级较低的已经接 入的用户设备， 移动性管理网元或者 non-3GPP GW发送一个分离请求消息到 优先级较低的用户设备， 消息中可以携带指示信息指示用户设备分离请求是 由于用户设备数超过准入的用户设备数导致的， 如消息中携带 Cause 原因值 为 "Access number exceed CSG Al lowed Access Number "指示用户设备接 入数受限。 根据这个指示信息， 该用户设备可以启动一个定时器， 在这个定 时器所规定的时间内， 该用户设备将不再选择当前接入的控制网元来接入， 该用户设备无需将当前的 CSG ID地址从自己的准入 CSG列表中删除。
需要说明的是： 本专利中不限定允许请求接入的用户设备接入和移动性 管理网元或者 non-3GPP GW分离低优先级的用户设备的先后处理顺序。 如， 移动性管理网元或者 non-3GPP GW可以先允许请求接入的用户设备接入， 后 再分离低优先级的用户设备； 或者， 移动性管理网元或者 non-3GPP GW可以 先分离低优先级的用户设备， 后再允许请求接入的用户设备接入； 或者， 移 动性管理网元或者 non-3GPP GW可以先分离低优先级的用户设备， 拒绝请求 接入的用户设备接入， 在低优先级的用户设备分离后再收到用户设备请求接 入时允许请求的用户设备接入。

906. 如果接入网元侧的接入资源存在，则移动性管理网元或者 non-3GPP GW通知接入网元释放资源。
本发明实施例中， 移动性管理网元或者 non-3GPP GW分离优先级较低的 用户设备包括： 移动性管理网元或者 non-3GPP GW发送分离请求消息给用户 设备； 用户设备回分离接受消息给移动性管理网元或者 non-3GPP GW; 移动性 管理网元或者 non-3GPP GW通知接入网元释放资源， 完成将优先级较低的用 户设备分离， 同时允许优先级较高的用户设备接入， 从而实现差异化的服务 处理， 增加用户的体验。
需要说明的是， 在本发明实施例中， 接入设备是移动性管理网元或者 non-3GPP GW, 控制网元是接入网元或者 CSG区域， 接入网关是可选的网元， 如果存在接入网关， 则接入网元通过接入网关与其它网元进行交互， 如果没 有接入网关， 则接入网元直接与其它网元进行交互。
本发明实施例所提供的方法也能应用到其它的资源不足时的处理， 如移 动性管理网元或者 non-3GPP GW收到一个用户设备的业务建立请求时， 移动 性管理网元或者 non-3GPP GW确定所述用户设备所接入的接入网元或者 CSG 区域中的资源不能满足所述用户设备的业务需要时， 移动性管理网元或者 non-3GPP GW判断接入网元或者 CSG区域中已经接入的用户设备是否有优先级 低于请求业务建立的用户设备。 如控制网元的成员列表内的客人的优先级低 于控制网元的成员列表内的朋友、 控制网元的成员列表内的朋友的优先级低 于控制网元的成员列表内的成员 （控制网元的成员列表内的用户设备的优先 级的获取参见前面的描述）， 或者非控制网元用户 （即， 不在控制网元的成员 列表内的用户， 如不在 CSG 的成员列表内的用户） 优先级低于控制网元用户 (这时， 控制网元的成员列表内的用户设备可能没有优先级， 则家庭接入管 理服务器、 归属用户服务器或者运营商的后台系统只需将控制网元的成员列 表信息发给移动性管理网元或者 non-3GPP GW或者发给接入网元或者接入网 关， 由接入网元或者接入网关通知给移动性管理网元或者 non-3GPP GW) 等； 如果没有，则拒绝请求建立的业务；如果有，移动性管理网元或者 non-3GPP GW 则允许请求建立的业务建立， 同时移动性管理网元或者 non-3GPP GW在接入 网元或者 CSG区域所接入的用户设备中分离低优先级的用户设备， 分离低优 先级的用户设备具体参照本发明实施例中的描述。
