上述各执行主体在授权处理过程中可以采用授权处理策略, 授权处理策略的一个具体例子: 终 端设备请求的业务优先级信息与终端设备的签约业务优先级信息匹配时, 允许按照终端设备请求的 业务优先级将终端设备优先接入, 即, 将终端设备请求的业务优先级信息作为授权后优先服务信息。 授权处理策略的另一个具体例子: 终端设备请求的业务优先级信息与终端设备的签约业务优先级信 息不匹配时, 拒绝终端设备接入、 或者允许将终端设备作为普通终端设备接入或者允许按照签约业 务优先级信息将终端设备优先接入、或者允许按照缺省设置的业务优先级将终端设备优先接入等等。 上述缺省设置的业务优先级应不高于签约业务优先级信息, 如可以为最低的业务优先级信息。 本实 施例不限制授权处理策略包括的具体策略。
在上述描述中, 如果将终端设备的信令进行排队, 则执行排队操作的网络设备可以为终端设备 设置定时时长, 如果在定时时长所示的预定时间间隔内该终端设备的信令仍处于排队状态, 则执行 排队操作的网络设备可以将终端设备作为未设置有优先服务权限的终端设备进行处理, 也可以释放 为该终端设备已分配的资源。 上述为终端设备设置的定时时长可以根据该终端设备的业务优先级信 息来确定, 如为业务优先级信息高的终端设备设置较长的定时时长, 为业务优先级信息低的终端设 备设置较短的定时时长等。
在上述描述中, 如果网络设备的资源受限, 如移动性管理网元或者无线接入网元或者网关设备 等网络设备的资源受限, 则网络设备可以通知应用功能单元, 以使应用功能单元保留该终端设备的 会话资源。
从上述实施例一的描述可知, 实施例一在接收到接入请求消息后, 通过判断是否获取到终端设 备的优先服务信息, 可以决定出是否允许将用户设备优先接入网络, 从而实现了增强型多媒体优先 权业务和紧急通信业务。 实施例一给出了多种不同的实现方案, 可以满足多种不同的网络需求。
实施例二、在 3GPP网络中终端设备优先接入的业务实现方法。在 3GPP网络中, 优先服务信息 可以称为 eMPS信息或其它名称。 本实施例不限制优先服务信息在 3GPP网络中的具体称谓。 该方 法的流程如附图 2所示。
图 2中, Sl、 UE (用户设备)通过 RAN (无线接入网元) 向网络侧发送接入请求消息, 这里的 RAN如 eNodeB或者 NodeB等。 可选的, 该接入请求消息中包含有 eMPS信息, 该接入请求消息中 的 eMPS信息可以被称为 UE请求的 eMPS信息。
该接入请求消息具体可以体现为: Attach Request (附着请求)消息或者 Packet Data Network (分 组数据网, PDN)连接建立请求消息或者 Tracking Area Update Reques (跟踪区更新消息)或者 Service Request (服务请求) 消息或者 UE Request Bearer Resource Modification (UE请求承载资源修改) 消 息等等。 本实施例不限制 UE发送的接入请求消息具体表现出的消息名称。

53、移动性管理网元接收 RAN转发的接入请求消息,并从接入请求消息中获取 UE请求的 eMPS 信息。 移动性管理网元向归属地签约数据服务器 (如 HSS/HLR) 发送 Update Location (更新位置) 消息。
可选的, 在移动性管理网元资源受限的情况下, 本实施例还可以包括 S2b和 /或 S2b00。
S2b、 移动性管理网元将 UE的接入请求消息放入队列中排队, 并向 UE发送通知, 以告知 UE 已进入排队队列中等候处理 (即己处于排队状态) 等排队信息。 移动性管理网元可以釆用 Queue indication (队列指示) 消息来通知 UE, 通知 UE排队信息的消息名称在本实施例中不作限制。
S2b00、移动性管理网元可以通过 S-GW、P-GW以及 PCRF等网元通知 AF该 UE处于排队状态, 使 AF为该 UE保留会话资源而不能发起释放 AF Session (AF会话)过程。本实施例不限制通知 AF 的消息名称以及具体通知方式。
为了保证优先级高的用户接入网络, 移动性管理网元可以将普通用户或者低优先级的用户的部 分或全部承载释放, 或者将低优先级的用户分离。 另外, 移动性管理网元还可以向网关设备 (如服 务网关 S-GW)发送拥塞信息, 如移动性管理网元向网关设备发送 Congestion Indication (拥塞指示) 消息, 发送拥塞信息所使用的消息名称在本实施例中不作限制。 网关设备接收到拥塞信息后, 可以 执行相应的拥塞处理, 例如, 网关设备可以在接收到 eMPS优先级较低的或者不具有 eMPS优先级 的用户的 Downlink Data Notification (下行数据通知)消息后, 不再向该移动性管理网元转发该下行 数据通知消息, 从而不再通过该移动性管理网元发起寻呼等, 以缓解该移动性管理网元的资源受限 情况。
需要说明的是, 本实施例不限制 S2b、 S2b00和 S3的执行先后顺序。 另外, S2b中通知 UE排 队信息的过程和 S2b00还可以采用其它方式, 如采用下述 S2b01至 S2b03所述的方式通知 UE排队 信息并通知 AF:

移动性管理网元可以根据签约数据消息中包含的签约 eMPS信息、 利用 eMPS授权处理策略对 UE请求 eMPS信息进行授权, 授权的几种方式可以是以下几种:
策略 1、 在 UE请求的 eMPS信息与中的 eMPS Priority与签约 eMPS Priorit 不同时, 拒绝 UE 的接入请求。 移动性管理网络可以根据策略 1向 UE发送接入拒绝消息。
策略 2、 在 UE请求的 eMPS信息中的 eMPS Priority高于签约 eMPS Priority时, 不允许 UE基 于请求的 eMPS Priority信息接入, 允许将 UE作为普通 UE接入。
策略 3、在 UE请求的 eMPS信息中的 eMPS Priority高于签约 eMPS Priority信息时,不允许 UE 基于请求的 eMPS Priority信息接入, 可以允许 UE基于 eMPS签约数据中的签约 eMPS Priority信息 接入。
策略 4、在 UE请求的 eMPS信息中的 eMPS Priority高于签约 eMPS Priority信息时,不允许 UE 基于请求的 eMPS信息中的 eMPS Priority信息接入, 允许 UE基于预先缺省设置的 eMPS Priority信 息接入。
策略 5、在接入请求消息中不包含 UE请求的 eMPS信息或者接入请求消息中的 UE请求的 eMPS 信息不包含 eMPS Priority信息时或者 eMPS信息包含在 PCO信元中时,可以允许 UE基于 eMPS签 约数据中的签约 eMPS Priority信息 (如签约 eMPS Priority列表中的最高签约 eMPS Priority信息或 者最低 eMPS Priority信息等) 接入。
设定在本实施例中, 允许 UE基于 eMPS (即授权后的 eMPS) 信息接入。
S5、 移动性管理网元向 S-GW发送 Create Session Request (创建会话请求) 消息, 或者在服务 请求过程中移动性管理网元向 S-GW发送 Modify bearer request (修改承载请求)消息,或者在 UE发起 的资源修改过程中移动性管理网元向 S-GW发送 bearer resource command (承载资源命令) 消息。
S-GW向 P-GW发送创建会话请求消息或者 Modify Bearer Request (修改承载请求) 消息或者 bearer resource command (承载资源命令)消息。上述创建会话请求消息或者修改承载请求消息或者承载资 源命令消息中可以包含有授权后的 eMPS信息。授权后的 eMPS信息可以包括 eMPS Indicator和授权 eMPS Priority信息中的至少一个。 授权后的 eMPS信息在消息中的承载方式可以如上述 UE请求的 eMPS信息在接入请求消息中的描述, 在此不再重复说明。
如果移动性管理网元资源受限, 则移动性管理网元可以通知 S-GW, 例如向 S-GW发送拥塞信 息, 例如, 移动性管理网元向 S-GW发送拥塞指示消息; 移动性管理网元也可以采用信元的方式通 知 S-GW, 如移动性管理网元在创建会话请求消息包含的信元中包含 resource limited indication (资 源受限指示),并向 S-GW发送创建会话请求消息。本实施例不限制移动性管理网元通知 S-GW资源 受限的具体实施方式。 S-GW在接收到移动性管理网元的通知后, 可以釆用不再向该移动性管理网 元发送寻呼消息等减缓拥塞的操作。
如果 S-GW资源受限, 贝 Ij S-GW可以通知 P-GW。 本实施例不限制 S-GW通知 P-GW资源受限 的具体实施方式。 P-GW接收到 S-GW发送来的资源受限的通知后, 可以执行减缓该 S-GW拥塞的 操作,如仅向该 S-GW下发具有 eMPS优先级的用户的下行数据包,不向该 S-GW下发不具有 eMPS 优先级的用户的下行数据包等。 本实施例不限制 S-GW和 P-GW执行的减缓拥塞的具体操作。
值得说明的是: 在 S-GW或者 P-GW资源受限时, 也可以将该 UE的信令放入队列中等待处理, 并通知 UE。 具体的通知 UE的方式可以为: S-GW或者 P-GW通过移动性管理网元通知 UE; 也可 以为: S-GW与 P-GW通知 PCRF, PCRF通知 AF, 由 AF通知 UE。 AF可以保留为 UE成功建立的 AF会话资源。
如果采用 Policy and Charging Control (策略与计费控制, PCC) 构架, 则本实施例在 S5之后还 可以包括 S5aa。
S5aa、 P-GW向 PCRF发起 IP Connectivity Access Network (IP连接接入网, IP-CAN)会话建立 过程,通知 PCRF该 UE的授权后的 eMPS信息, PCRF可以根据 UE的授权后的 eMPS信息制定 PCC rule (PCC规则),并向 P-GW下发 PCC 规则。制定 PCC规则的一个具体的例子: 将该用户的 eMPS 信息映射到用户承载的 QoS (服务质量)中,包括信令承载以及用户面数据承载等。对于巳经建立的承 载, PCRF可以发起修改 QoS的承载修改过程, 比如将 Allocation and Retention Priority (分配与抢占 优先级, ARP) 提高。
PCRF可以通知 PCEF订阅 eMPS签约数据改变通知事件,通知所釆用的消息的具体表现形式在 本实施例中不作限制, 一个具体的例子: PCRF在 Change Reporting Action (报告改变行动)信元中 增加枚举值 Start Reporting eMPS information等 (开始报告 eMPS信息), 以便使 PDN GW(PDN GW 可以与 PCEF合建在一个网络实体中)能够在该 UE的 eMPS签约数据改变时通知 PCRF,从而 PCRF 可以根据变化后的该 UE的 eMPS签约数据修改该 UE的承载的 QoS和 /或计费规则等。 上述 PCEF 可以通过以下方式获知更新后的 eMPS签约数据: 1、 PCEF通过服务网关设备向移动性管理网元发 送 PCC订阅 eMPS信息改变事件; 2、 当移动性管理网元获知签约数据改变时, 移动性管理网元将 最新的 eMPS信息通过服务网关传输至 PDN GW (PDN GW可以与 PCEF合设), PDN GW将最新 的 eMPS信息通知 PCRF。 之后, PCRF可以根据 eMPS信息更新 PCC rule, 针对 eMPS信息改变, PCRF可以发起修改 QoS的承载修改过程。
S5a、 P-GW向 S-GW发送 Create Session Response (创建会话响应) 消息或者 Modify bearer response (修改承载响应) 消息, S-GW向移动性管理网元转发创建会话响应消息。 如果 PCRF订阅 了 eMPS信息改变报告事件, 那么 S5a中 P-GW向 S-GW发送的消息、 以及 S-GW向移动性管理网 元发送的消息中可以包括 Change Reporting Action信元, 从而可以使移动性管理网元可以在 UE的 eMPS签约数据发生变化时, 向 PCC构架上报更新后的 eMPS签约数据。
P-GW、 S-GW、移动性管理网元可以根据消息中显示或隐式携带的授权后的 eMPS信息对该 UE 的信令进行优先处理。 在网关设备 (如 P-GW或者 S-GW) 资源受限的情况下, 本实施例还可以包 括 S5b。
S5b、 网关设备释放低优先级的 UE的承载资源, 以保证高优先级的 UE能够接入。 这里的低优 先级的 UE如非 eMPS的 UE或者虽然是 eMPS但是授权 eMPS Priority信息较低的 UE。
如果释放了低优先级的 UE的承载资源后, 网关设备的资源仍然受限, 则对于高优先级的 UE, 网关设备可以根据 UE的 QoS抢占资源, 以保证 QoS髙的 UE优先获得资源。 如果具有相同优先级 的 UE发生拥塞, 则网关设备可以向移动性管理网元发送资源受限通知, 由移动性管理网元通知 UE 资源受限; 网关设备可以将 UE的信令放入队列中排队,网关设备可以向移动性管理网元发送 Queue Indication (排队指示) 消息, 由移动管理网元向 UE发送排队指示消息, 使 UE获知其正处于排队 状态以及具体的排队信息等。

在 RAN资源受限时, 本实施例可以可选的包括 S6b。
S6b、 RAN释放低优先级的 UE的承载资源, 以保证高优先级的 UE接入网络, 如果在资源释放 后, RAN的资源仍然受限, 则对于具有相同优先级的 UE可以根据 UE的 QoS抢占资源, 以保证 QoS高的 UE优先获得资源。 如果在释放了低优先级的 UE的资源后, RAN资源仍然受限, 则 RAN 可以通知 UE将其排队处理, 同时也可以向移动性管理网元通知资源受限, 由移动性管理网元通知 UE资源受限; RAN可以将该 UE的初始上下文建立请求消息或者 RAB分配请求消息放入队列中排 队, RAN可以向移动性管理网元发送 Queue Indication (排队指示)消息, 由移动管理网元向 UE发 送排队指示消息, 使 UE获知排队信息, 如正处于排队状态以及具体的队列信息等。 移动性管理网 元可以将 UE处于排队状态的消息通过 S-GW、 P-GW, PCRF等网元通知 AF, AF保留该 UE的 AF 会话资源。 通知 UE排队信息的过程也可以釆用其它方式, 具体如本实施例中上述步骤中的描述, 在此不再重复说明。
在上述 S2b、 S5b或者 S6b中, 如果将 UE的信令放入队列中进行排队, 则移动性管理网元或者 网关设备或者 RAN 可以针对排队的 UE 启动定时器, 定时器的定时时长可以根据请求的 eMPS Priority信息或者授权 eMPS Priority信息来设置,高优先级对应的定时时长可以大于低优先级对应的 定时时长, 当然, 不同优先级对应的定时时长也可以相同。 在定时器超时时, 可以将 UE作为普通 的 UE进行处理。 同样地, 当 AF接收到该 UE处于排队状态的消息后, 也可以启动定时器, 如果定 时器超时, 则将该 UE的 AF会话资源释放。
其中, AF获知资源是否受限也可以采用另外一种方式:
PCRF向承载网订阅资源满足的事件, 比如 PCRF向 PDN GW订阅资源满足事件, 具体可以包 括 PCRF向 PDN GW发送 resource not limited report指示 PDN GW报告资源是否受限报告, PDN GW 也可以向 S-GW、 MME、 接入网元等网元发送资源是否受限的报告事件。 进一步的, 当所述网元设 备资源受限或者资源不受限时, 通过 S-GW、 P-GW等通知 PCRF资源受限或者资源不受限, PCRF 将资源是否受限的事件通知 AF, 如果资源受限, AF可以保留该用户的 AF会话资源, 并记录该用 户己处于排队状态, 可选地, 也可以通知 UE其处于排队状态, 如果 AF获知了资源不受限满足, 那 么 AF也可以通知上层应用, 重新申请当前会话的承载资源。
S7、 RAN和移动性管理网元分别向 UE发送接入请求接受消息, 即 eMPS接入应答消息。 接入 请求接受消息具体可以为 Attach Accept (附着接受) 消息或者 PDN Connectivity Accept (PDN连接 建立接受) 消息等。 本实施例不限制接入请求接受消息的具体消息名称。 对于有业务优先接入权限 的用户, RAN和 /或移动性管理网元可以在 Attach Accept消息等接入请求接受消息中包含指示该 UE 业务优先接入请求接受的信息,一个具体的例子:使用接入请求接受消息中的 eMPS activated (eMPS 激活)信元或者使用接入请求接受消息的 Additional update result (条件更新结果)信元中增加的 eMPS activated枚举值等来表示该用户业务优先接入请求接受,具体的指示 UE业务优先接入的实现形式在 本实施例中不作限制。
从上述实施例二的描述可知,实施例二中 UE通过向网络侧发送 UE请求的 eMPS信息,使移动 性管理网元可以在资源受限时将该 UE的信令进行排队,避免了移动性管理网元拒绝 UE接入的现象; 移动性管理网元通过根据该 UE的 eMPS签约数据对该 UE请求的 eMPS信息进行授权处理,保证了 UE可以获得合理的业务优先接入权限; PCRF通过利用授权后的 eMPS信息来制定 QoS, 使具有 eMPS权限的 UE可以具有高优先级的 QoS; 另夕卜, 授权后的 eMPS信息可以使移动性管理网元、 网 关设备以及 RAN等在资源受限的情况下, 优先将该 UE接入网络; 从而实施例二实现了 eMPS。
实施例三、 在 3GPP网络中用户设备优先接入的业务实现方法。 该方法的流程如附图 3所示。 图 3中, Sl、 UE通过 RAN向网络侧发送接入请求消息, 这里的 RAN如 eNodeB或者 NodeB 等。可选的, 该接入请求消息中包含有 eMPS信息, 该接入请求消息中的 eMPS信息可以被称为 UE 请求的 eMPS信息。 UE请求的 eMPS信息可以包含在接入请求消息的 Protocol Configuration Options (协议配置选项, PCO) 信元中。 UE请求的 eMPS信息可以包括: eMPS Indicator和 eMPS Priority 信息中的至少一个。 eMPS Indicator可以占用一个比特位或多个比特位, 一个具体的例子: eMPS Indicator可以采用特定的字符串来表示, 如 17950等。
