为使本发明实施例的目的、 技术方案和优点更加清楚明白, 下面结合实 施例和附图, 对本发明实施例做进一歩详细说明。 在此, 本发明的示意性实 施例及其说明用于解释本发明, 但并不作为对本发明的限定。
如图 1所示, 由于 eNodeB在用户处于连接状态时, 保存用户信息, 当 用户不处于连接态时, eNodeB 会删除用户信息。 从以上的技术方案可以看 出, 只有当 MME接收用户设备发送的服务请求消息后, eNodeB才能获取 "Subscriber Type"参数 (歩骤 5), 从而执行相应的控制策略, 而当用户设备 发起接入请求 RRC Connection Request 消息到 eNodeB 时 (歩骤 1), 此时 eNodeB上并没有用户设备的相关信息,包括" Subscriber Type",如果 eNodeB 资源紧张需要限制用户接入, eNodeB 没有任何依据作为参考对用户设备进 行接入控制, 必须等到 MME将 "Subscriber Type"传递到 eNodeB后才能进 行策略控制。
如图 2A所示, 为本发明实施例提供的接入控制方法的流程图, 该方法 包括:
201a, 接入控制网元接收用户设备发送的接入请求消息, 所述接入请求 消息中包括网络侧为该用户设备分配的临时标识,所述临时标识中包含有用 户的服务策略信息;
203a, 接入控制网元根据所述临时标识中包含的服务策略信息, 对用户 设备进行接入控制处理。
其中, 所述服务策略信息可以包括用户等级信息和 /或业务服务等级信 息, 用户等级信息可以为用户的优先等级或者用户类型等信息, 如是否为
VIP用户等, 业务服务等级信息可以包括用户可以使用的业务, 比如当网络 资源紧张时, 只允许用户使用紧急业务。
临时标识可以包括: P-TMSI、 S-TMSK GUTI、 TLLI或者 TMSI。 如图 2B所示, 为另一本发明实施例提供的接入控制方法的流程图, 该 方法包括:
201b, 网络侧向用户设备下发临时标识的过程中, 在临时标识中携带该 用户的服务策略信息;
203b, 接入控制网元接收用户设备发送的接入请求消息, 所述接入请求 消息中包括网络侧为该用户设备分配的临时标识,所述临时标识中包含有用 户的服务策略信息; 205b, 接入控制网元根据所述临时标识中包含的服务策略信息, 对用户 设备进行接入控制处理。
其中 201b, 网络侧向用户设备下发临时标识的过程可以包括: 在用户设备附着过程中, 网络侧向用户设备发送携带临时标识的附着接 受消息; 或者
在用户设备位置区更新过程中, 网络侧向用户设备发送携带临时标识的 位置区更新接受消息; 或者
在用户设备临时标识重分配过程中, 网络侧向用户设备发送携带临时标 识的临时标识重分配请求消息。
在本实施例中, 网络侧可以根据用户的签约数据或者运营商配置信息或 者网络侧设备的负载状况或者以上三种的任意组合,确定用户设备的服务策 略信息。
上述实施例中 203a或 205b中接入控制网元根据所述临时标识中包含的 服务策略信息, 对用户设备进行接入控制处理包括:
根据服务策略信息, 接受或者拒绝该用户设备的接入请求; 或者 根据服务策略信息, 接受用户设备的接入请求, 但为用户设备提供部分 业务。
例如, 当网络资源紧张时, 接入控制网元可以根据用户设备的服务策略 信息中的用户等级信息, 拒绝低优先级的用户, 而只接入高优先级的用户, 或者根据服务策略信息中的业务服务等级信息, 接入用户设备的接入请求, 但只接受部分高优先级的业务, 例如紧急业务等。 接入控制网元可以为接入 设备, 如 NodeB、 RNC或 eNodeB等, 也可以为进行接入控制的移动性管理 实体或者电路域中的移动交换中心。
通过上述实施例提供的接入控制的方法,使得接入控制网元在接收到用 户设备发起的接入请求时, 就可以根据接入请求中携带的临时标识中的服务 策略信息, 对该用户设备进行接入控制处理, 而不需要等到移动管理网元接 收到用户设备发送的服务请求后,才能够将表示用户服务等级策略的信息发 送至接入网元, 尤其是在网络资源紧张等情况下, 根据该服务策略信息拒绝 接入请求, 从而减少了当前接入设备的负荷, 提高了设备运行的稳定性和安 全性。
以下通过几个实施例说明一下网络侧如何将包含服务策略信息的临时 标识发送至用户设备。
如图 3所示, 为本发明实施例中用户设备在附着过程中, 网络侧向用户 设备发送包含服务策略信息的临时标识的方法流程图, 该方法包括:

306、 HSS向目标移动性管理网元插入用户签约数据。
307、 目标移动性管理网元验证用户合法性, 向 HSS返回插入签约数据 确认消息。
308、 HSS向目标移动性管理网元发送位置更新确认消息。
309、 如果用户设备可以在当前位置接入, 目标移动性管理网元向用户 设备发送附着接受消息, 消息中携带该用户设备的临时标识, 并在该临时标 识中携带用户的服务策略信息, 具体的, 目标移动性管理网元可以根据运营 商配置, 目标移动性管理网元当前负载或者用户的签约数据之一或任意组 合, 来确定用户设备的服务策略信息。
如图 4所示, 为本发明实施例中用户设备在位置区更新过程中, 网络侧 向用户设备发送包含服务策略信息的临时标识的方法流程图, 该方法包括:
401、 用户设备向目标移动性管理网元发送路由区更新请求消息 (在 GERAN(GSM EDGE Radio Access Network, GSM EDGE无线接入网络)或 UTRAN(UMTS Territorial Radio Access Network UMTS陆地无线接入网)用 路由区的概念:)或跟踪区更新请求消息 (在 LTE(Long Time Evloved, 长期演进 网络:)中用跟踪区的概念:), 路由区或者跟踪区可以统称为位置区, 因此本发 明实施例中, 将路由区更新或者跟踪区更新统称为位置区更新。
402、 目标移动性管理网元收到路由区或跟踪区更新请求消息后, 如果 该路由区或跟踪区更新请求消息中携带有临时标识, 且临时标识是其他移动 性管理网元 (源移动性管理网元:)分配, 目标移动性管理网元向源移动性管理 网元发送上下文请求消息, 请求用户上下文。
403、 收到更新请求消息后, 源移动性管理网元向目标移动性管理网元 发送上下文响应消息, 返回用户上下文。
404、 收到用户上下文信息后, 目标移动性管理网元保存用户上下文并 向源移动性管理网元发送上下文确认消息。
405、 由于移动性管理网元发生改变, 目标移动性管理网元向服务网关 发送承载更新请求消息,更新承载,接收服务网关返回的承载更新响应消息。

409、 目标移动性管理网元向用户设备发送路由区或跟踪区接受消息, 在路由区或跟踪区接受消息中携带目标移动性管理网元为用户设备分配的 临时标识, 并在临时标识中携带用户设备的服务策略信息, 例如, 目标移动 性管理网元可以根据运营商配置, 移动性管理网元当前负载或者用户的签约 数据之一或任意组合, 来确定用户设备的服务策略信息。 比如运营商可以配 置某一个移动性管理网元 MME或 SGSN上的接入的用户优先级都比较低或 者比较高。
如图 5所示, 为本发明实施例中临时标识重分配过程中, 网络侧向用户 设备发送包含服务策略信息的临时标识的方法流程图, 该方法包括:
501、 如果用户签约数据发生变化, 或者因为安全等原因移动性管理网 元可以为用户重新分配临时标识, 移动性管理网元向用户设备发送临时标识 重分配请求, 并在临时标识重分配请求中携带包含用户设备的服务策略信息 的临时标识。 例如, 当用户设备通过 E-UTRAN接入时, 该临时标识重分配 请求可以是 GUTI Reallocation Command, 当用户设备通过 UTRAN (UMTS Territorial Radio Access Network UMTS陆地无线接入网)接入时, 该临时 标识重分配请求可以是 P-TMSI Reallocation Command;移动性管理网元可以 根据运营商配置, 移动性管理网元当前负载或者用户的签约数据之一或任意 组合, 来确定用户设备的服务策略信息。
503、 收到消息后, 用户设备向移动性管理网元发送临时标识重分配完 成消息, 该消息可以为 GUTI/P-TMSI Reallocation Complete。

603、 用户设备向网络侧发送位置更新完成消息。
上述实施例中, 在不同的场景下, 网络侧为用户设备分配的临时标识名 称可能不同, 临时标识的组成也可能有所差别。 例如, 当用户设备通过 GERAN网络接入 PS网络时, 接入网元为 BSS, 网络侧为用户设备分配的 临时标识为 TLLI; 当用户设备通过 UTRAN接入时, 接入网元为 NodeB或 RNC, 网络侧为用户设备分配的临时标识为 P-TMSI ( Packet Temporary Mobile Subscriber Identity) 分组临时移动用户身份标识; 当用户设备通过 E-UTRAN接入时, 接入网元为 eNodeB, 网络侧为用户设备分配的临时标识 为 GUTI ( Globally Unique Temporary Identity ) 全球唯一临时标识或 S-TMSI ( SAE Temporary Mobile Subscriber Identity ) SAE临时移动用户身份标识; 当用户设备通过电路域接入时, 接入网元为 BSS或者 RNC, 网络侧为用户 设备分配的临时标识为 TMSI ( Temporary Mobile Subscriber Identity )。
下面说明一下如何在临时标识中携带用户服务策略信息。
一、 GUTI
GUTI 由 MNC+MCC+MMEGI+MMEC+S-TMSI 组成, MNC (Mobile Network Code)为移动网编码, MCC (Mobile Country Code)为移动国家码, MMEGI (MME Group Indentity)为移动管理网元群组标识, MMEC (MME Code) 为移动管理网元编码, S-TMSI ( SAE Temporary Mobile Subscriber Identity) 为 SAE临时移动用户身份标识, 其中 S-TMSI由 32个 bit组成。 本发明实施例中可以采用在 S-TMSI的低 2位作为用户的服务策略信息, 当 然, 也可以采用其他位置的两位或者多位来作为用户的服务策略信息。
二、 P-TMSI、 TLLI、 TMSI、 S-TMSI
Ρ-TMSL· TLLI、 TMSI或者 S-TMSI均由 32个 bit组成, 可以采用其低
2位或低 3位用作用户的服务策略信息, 当然也可以采用其他位置的两位或 者多位来作为用户的服务策略信息。
表 1列出了如何在 S-TMSI、 P-TMSK TMSI或 TLLI中来携带服务策略 信息中的用户等级信息。
表 1
Figure imgf000014_0001
说明: 当前协议规定用户进行的业务可以分为四个等级, 由高到低的顺 序为: 会话类、 流类、 交互类、 背景类业务。
通过上面的实施例介绍,用户设备在上述过程中就可以从网络侧获取包 含服务策略信息的临时标识, 这样当用户设备再向网络侧发起接入请求时, 就可以携带包含服务策略信息的临时标识, 这样接入控制网元就可以根据临 时标识中的服务策略信息对用户设备进行接入控制。
如图 7所示, 为本发明实施例另一个接入控制方法实施例的流程图, 如 图所示, 该方法包括:
701、 用户设备向接入网元发送无线资源建立请求, 如 RRC Connection Request 消息, 并在该无线资源建立请求中携带包含用户设备服务策略信息 的临时标识,在不同的接入场景下,临时标识可以是 P-TMSI、S-TMSI、GUTI。
如果临时标识中携带业务策略信息, 用户设备在发送 RRC Connection Request请求时, 还需要携带即将进行的业务类型, 比如紧急呼叫业务。
702、 接入网元收到无线资源建立请求后, 从用户设备的临时标识中获 取用户设备的服务策略信息, 例如在上述实施例中介绍的, 在 P-TMSI或者 S-TMSI或者 GUTI的某一段特定字段, 比如低两位字段来获取用户设备的 服务策略信息,接入网元可以根据用户设备的服务策略信息来决定是否为用 户设备提供服务,或者提供那些业务的服务。如果接受用户设备的接入请求, 接入网元向用户设备发送请求接受消息, 比如: RRC Connection Setup消息; 如果不接受, 则向用户设备发送请求拒绝消息, 如 RRC Connection Reject, 拒绝消息中可以携带响应的原因值, 如: 业务不允许, 资源紧张等。 发送请 求拒绝的流程在图 7中没有出示,接入网元发送请求拒绝消息后结束该流程。
703、 如果接入网元接受了用户设备的无线资源请求, 则用户设备向接 入网元发送无线资源建立完成消息。
704、 无线资源分配完成后, 用户设备通过接入网元向移动性管理网元 发送 NAS(Non Access Stratum, 非接入层:)请求消息, 请求中携带包含用户设 备服务策略信息的用户临时标识, 或者, 用户设备在 NAS请求消息中不携 带临时标识, 而是由接入网元在中转 NAS消息的同时将包含用户设备服务 策略信息的用户临时标识传递给移动性管理网元。
在不同的应用场景下, 所述 NAS层请求消息可以是以下消息的一种: Service Request月艮务请求消息; Attach Request 附着请求消息;
RAU Request 路由区更新请求消息;
TAU Request 跟踪区更新请求消息; 或
Detach Request分离请求消息。
705、 移动性管理网元收到 NAS层的请求消息后, 从用户设备的临时标 识中获取用户设备的服务策略信息, 具体方式与 602中接入网元从用户设备 的临时标识中获取用户设备的服务策略信息相同, 在此不再赘述。 移动性管 理网元根据所述用户设备的服务策略信息以及网络负载等情况,对用户设备 进行接入控制, 例如, 接受用户设备的 NAS层请求消息, 则向用户设备发 送 NAS层接受消息,或者拒绝该 NAS层请求消息,则向用户设备发送 NAS 层拒绝消息, 或者接受用户设备的 NAS层请求消息但为用户设备提供有差 别的服务, 例如为高优先级的用户提供全业务的服务, 为低优先级的用户只 提供基本业务的服务, 或者只接受紧急业务的服务等。
根据应用场景的不同,所述的 NAS层接受消息或 NAS层拒绝消息可以 是与所述 NAS层请求消息对应的消息,表 3列出了不同 NAS层请求消息与 NAS层接受消息或 NAS层拒绝消息的对应关系。
表 3
Figure imgf000016_0001
求消息 绝消息
TAU Request TAU Accept TAU Reject 跟踪区更新请 跟踪区更新接受消息 跟踪区更新拒 求消息 绝消息
Detach Detach Accept 无
Request 分离接受消息
分离请求消息
以上实施例中, 当 NAS层请求消息为附着请求消息或跟踪区更新请求 消息时, 如果移动性管理网元发生改变, 虽然此时目标移动性管理网元还没 有从 HSS 获取签约数据, 但是可以根据请求中携带的临时标识中的服务策 略信息, 来进行接入控制, 如决定是否为用户提供服务等。 这样, 在移动性 管理网元负载很重的情况下, 就可以拒绝部分低优先级用户的服务请求, 就 不需要再与 HSS 交互等操作, 减轻了该设备的负载, 保证了网络设备的安 全运行。
如图 8所示, 为本发明实施例中电路域中接入控制方法的流程图, 该方 法包括:
801、 用户设备 UE首先向接入网元发送信道请求;
802、 接入网元分配无线信道资源给用户设备;
803、用户设备向接入网元发送 SABM帧,请求接入到网络中,该 SABM 帧可以认为是一种接入请求消息, 帧中携带网络侧之前为用户设备分配的临 时标识 TMSI以及需要接入网元透传到移动交换中心的消息, 此时接入网元 可以根据 TMSI中的用户策略信息来决定是为用户传递消息还是拒绝;
804、 接入网元向移动交换中心透传用户设备发送的消息。
805、 移动交换中心收到该消息后, 可以根据 TMSI 中的用户策略信息 以及网络负载等情况, 对用户设备进行接入控制, 接受或者拒绝该消息, 如 果接受, 则向用户设备发送请求接受消息。 通过该实施例,实现了在传统的电路域网络中,在用户发起接入请求时, 根据网络侧为用户分配的临时标识中的服务策略信息,对该用户进行接入控 制。
如图 9所示, 为本发明实施例中 GERAN中接入控制方法的流程图, 该 方法包括:
901、 用户设备首先向接入网元发送信道请求;
902、 接入网元分配无线信道资源给用户设备;
903、用户设备向接入网元发送 SABM帧,请求接入到网络中,该 SABM 帧可以认为是一种接入请求消息, 帧中携带网络侧为用户分配的临时标识 TLLI 以及需要接入网元透传到移动管理网元的消息, 此时接入网元可以根 据 TLLI中的用户策略信息来决定是否为用户传递信息还是拒绝;
904、 接入网元向移动性管理网元透传消息;
905、移动性管理网元收到该消息后, 可以根据 TLLI中的用户策略信息 以及网络负载等情况, 对用户设备进行接入控制, 接受或者拒绝该消息, 如 果接受, 则向用户设备发送请求接受消息。
通过该实施例, 实现了在 GERAN网络中, 在用户发起接入请求时, 根 据网络侧为用户分配的临时标识中的服务策略信息, 对该用户进行接入控 制。
如图 10所示, 为本发明实施例中利用临时标识对用户进行群组寻呼的 方法流程图, 该方法包括:
1001、 接入网元接收网络侧下发的寻呼消息, 所述寻呼消息中携带有用 户临时标识或者用户分组信息,其中,所述临时标识中携带有用户群组信息; 其中, 如果某一群组用户相关的信令或者数据发送到网络侧而用户设备 又处于空闲状态时, 则移动性管理网元通过接入网元向用户设备发送寻呼消 息, 该寻呼消息中可以携带用户临时标识, 该临时标识中携带有用户群组信 息, 指示对哪些用户群组的用户设备进行寻呼; 或者, 该寻呼消息中也可以 直接携带用户分组信息, 即用户所属的群组信息, 例如群组标识, 指示对哪 些用户群组的用户设备进行寻呼。 比如: 当需要为 IPTV用户发送 IPTV优 惠信息时, 移动性管理网元可以将临时标识 "00"发送到接入网元, 由于预 先设定的临时标识 "00"对应 IPTV群组用户, 则通过接入网元寻呼 IPTV 用户。
1002、 如果寻呼消息中包括用户分组信息 (群组标识), 则接入网元接 收到寻呼消息后, 读取用户分组信息, 并寻呼属于所述用户分组的群组的用 户。
1003、 如果寻呼消息中包括用户临时标识, 则接入网元接收到寻呼消息 后, 读取该临时标识中的用户群组信息, 并寻呼属于所述用户群组的用户。
1004、 如果寻呼消息中包括用户临时标识, 而该临时标识中除了包含用 户的群组信息以外, 还包含服务策略信息, 贝 I」, 接入网元对属于所述群组中 的用户设备中在所述服务策略信息所指示范围的用户进行寻呼。
例如, 当接入网元资源紧缺或者过载时, 接入网元可以读取用户的服务 策略信息, 包括但不限于用户的优先级信息, 对属于所述群组的用户设备中 优先级较高的用户发起寻呼,对属于所述群组的用户设备中优先级较低的用 户不发起寻呼, 比如寻呼所述群组中的 VIP用户, 而不寻呼该群组中的普通 用户。
在本实施例中, 网络侧会为用户设备分配携带用户群组信息的临时标 识, 以便用户设备收到寻呼消息后, 根据该寻呼消息以及上述临时标识, 确 定是否对该寻呼进行响应。 例如, 如果该寻呼消息包括用户分组信息(群组 标识), 则用户设备根据该寻呼消息中的用户分组信息 (群组标识) 以及自 己的临时标识中包含的群组信息,确定自己是否属于被寻呼的群组,如果是, 则响应寻呼消息, 响应的方式包括但不限于: 向网络侧发送 CM Service Request消息, 或者发送上行数据包, 或者发送 Service Request消息。 或者, 如果该寻呼消息中包括用户临时标识,那就说明本用户设备为所述临时标识 中携带的用户群组信息中的用户, 则用户设备直接响应该寻呼消息, 响应的 方式包括但不限于: 向网络侧发送 CM Service Request消息, 或者发送上行 数据包, 或者发送 Service Request消息。
本实施例的群组寻呼方法, 通过网络侧为用户设备分配临时标识, 来利 用临时标识对用户设备进行分组, 作分组管理, 网络侧在寻呼时仅提供分组 信息, 比如群组标识, 用户设备即利用网络侧为其分配的临时标识和该群组 标识,来确定是否对该寻呼进行响应,达到了用户设备快速响应寻呼的效果。 另外, 通过在临时标识中携带服务策略信息, 为接入网元有选择的进行寻呼 提供了依据, 使接入网元在资源有限时, 可以仅选择优先级高的用户设备进 行寻呼。
如图 11 所示, 为本发明实施例中用户设备利用临时标识响应寻呼的方 法流程图, 该方法包括:
1101: 用户设备接收接入控制网元下发的寻呼消息;
其中,接入控制网元会根据网络侧下发的寻呼消息所携带的用户分组信 息或者临时标识选择寻呼的对象, 具体已在图 10中的实施例说明, 在此不 再赘述。
1102: 如果所述寻呼消息中包含临时标识, 则用户设备对所述寻呼消息 进行响应;
其中, 如果寻呼消息中包含临时标识, 就表明接入控制网元是有选择的 进行寻呼, 而本用户设备为其所寻呼的对象之一, 因此, 该用户设备可以直 接对该寻呼进行响应。
1103: 如果所述寻呼消息中包含用户分组信息, 则用户设备根据所述用 户分组信息以及接收到的网络侧下发的临时标识,判断是否属于所述用户分 组信息中确定的群组, 如果是, 则对所述寻呼消息进行响应。
其中, 网络侧会向用户设备下发临时标识, 该临时标识中携带用户群组 信息, 具体可以为, 约定临时标识中某一位或者某些位的特定数值标识用户 属于哪个群组, 该标识可以是用户所属的群组标识, 比如:
表 4
Figure imgf000021_0001
需要强调的是, 本实施例仅以上表分类为例进行说明, 并不限定用户分 组的方式以及在临时标识中具体区分用户组的方式。
其中, 该临时标识还可以包括服务策略信息, 如前述实施例所述, 而该 临时标识下发的过程也与前述实施例相同, 在此不再赘述。
其中, 如果寻呼消息中包含用户分组信息, 就表明接入控制网元是有选 择的进行寻呼,但接入控制网元并不知道某一用户设备是否属于所述用户分 组信息之列, 所以接收到寻呼消息的用户设备, 还要根据接收到的网络侧下 发的临时标识, 来确定自己是否属于所述用户分组信息中确定的群组, 如果 是, 才对所述寻呼消息进行响应。
本实施例的群组寻呼方法, 通过网络侧为用户设备分配临时标识, 来利 用临时标识对用户设备进行分组, 作分组管理, 网络侧在寻呼时仅提供分组 信息, 比如群组标识, 用户设备即利用网络侧为其分配的临时标识和该群组 标识,来确定是否对该寻呼进行响应,达到了用户设备快速响应寻呼的效果。 另外, 通过在临时标识中携带服务策略信息, 为接入控制网元有选择的进行 寻呼提供了依据, 使接入网元在资源有限时, 可以仅选择优先级高的用户设 备进行寻呼。
如图 12所示, 为本发明实施例中一种接入控制的系统, 该系统包括: 临时标识分配网元 1201,用于为接入网络的用户设备下发临时标识,并 在临时标识中携带该用户的服务策略信息;

接入控制网元 1203,用于接收用户设备发送的接入请求消息,所述接入 请求消息中包括临时标识分配网元为该用户设备分配的临时标识, 根据所述 临时标识中包含的服务策略信息, 对用户设备进行接入控制处理。
其中,所述接入控制网元 1203对用户设备进行接入控制处理可以包括: 根据服务策略信息, 接受或者拒绝该用户设备的接入请求; 或者 根据服务策略信息, 接受用户设备的接入请求, 但为用户设备提供部分 业务。
由于在前述各方法实施例中已经详细描述了在各个网络中临时标识的 分配过程以及接入控制的方法, 在介绍系统实施例中将不在赘述。
该系统实施例中的临时标识分配网元 1201 可以为前述方法实施例中各 分配临时标识的网元, 例如移动性管理网元, 或者电路网络中的 MSC/HLR 等, 接入控制网元 1203可以为前述方法实施例中各接受用户设备接入请求 消息的接入网元, 例如 NodeB、 RNC或 eNodeB等, 也可以为进行接入控制 的移动性管理实体 SGSN或者电路域中的移动交换中心 MSC。 在实现具体 的系统实施例时, 均可参考前述方法实施例中的描述。

接入控制单元 1303,用于根据所述临时标识中包含的服务策略信息,对 用户设备进行接入控制处理。 其中所述服务策略信息可以包括用户等级信息和 /或业务服务等级信息, 用户等级信息可以为用户的优先等级或者用户类型等信息,如是否为 VIP用 户等, 业务服务等级信息可以包括用户可以使用的业务, 比如当网络资源紧 张时, 只允许用户使用紧急业务。
其中所述接入控制单元 1303还可以进一歩包括第一控制子单元 1305或 第二控制子单元 1307, 其中,
第一控制子单元 1305用于根据服务策略信息, 接受或者拒绝该用户设 备的接入请求, 例如根据服务策略信息中的用户等级信息, 判断是否接受该 用户设备的接入请求。
第二控制子单元 1307用于根据服务策略信息, 接受用户设备的接入请 求, 但为用户设备提供部分业务, 例如根据服务策略信息中的业务服务等级 信息, 判断可以为该用户提供哪些业务。
接入控制网元可以为前述方法实施例中各接受用户设备接入请求消息 的接入设备, 例如 NodeB、 RNC或 eNodeB等, 也可以为进行接入控制的移 动性管理实体或者电路域中的移动交换中心。 在实现具体的系统实施例时, 均可参考前述方法实施例中的描述。
如图 14所示, 为本发明实施例中一种通信系统中的临时标识分配网元, 该网元包括:
分配单元 1401, 用于为接入网络的用户设备分配临时标识;
插入单元 1403, 用于为分配单元 1401分配的临时标识中, 添加该用户 的服务策略信息;

进一歩的,该网元还可以包括确定单元 1407,用于根据用户的签约数据、 运营商配置信息或者网络侧设备的负载状况, 确定用户设备的服务策略信 息。 临时标识分配网元可以为前述方法实施例中各分配临时标识的网元,例 如移动性管理网元, 或者电路网络中的 MSC/HLR等, 分配临时标识的各种 方式与前述方法实施例相同,在临时标识中添加用户的服务策略信息的具体 方式也可参见前述方法实施例描述, 在此不再赘述。
通过上述实施例提供的接入控制的系统和网元,使得接入控制网元在接 收到用户设备发起的接入请求时, 就可以根据接入请求中携带的临时标识中 的服务策略信息, 对该用户设备进行接入控制处理, 而不需要等到移动管理 网元接收到用户设备发送的服务请求后,才能够将表示用户服务等级策略的 信息发送至接入网元, 尤其是在网络资源紧张等情况下, 根据该服务策略信 息拒绝接入请求, 从而减少了当前接入设备的负荷, 提高了设备运行的稳定 性和安全性。
如图 15所示, 为本发明实施例中一种接入控制网元的组成示意图, 该 接入控制网元包括:
接收单元 1501,用于接收网络侧下发的寻呼消息,所述寻呼消息中携带 有用户临时标识或者用户分组信息, 其中, 所述临时标识中携带有用户群组 ^ I 自、 .;
