具体实施方式
下面将结合本发明实施例中的附图,对本发明实施例中的技术方案进行清楚、完整地描述,显然,所描述的实施例仅仅是本发明一部分实施例,而不是全部的实施例。基于本发明中的实施例,本领域普通技术人员在没有作出创造性劳动前提下所获得的所有其他实施例,都属于本发明保护的范围。
参见图1,为本发明实施例的EPS的架构示意图,其中包括以下网元:
E-RAN(Evolved RAN,演进的无线接入网),能够提供更高的上下线速率,更低的传输延迟和更加可靠的无线传输,E-RAN中所包含的网元是eNodeB(Evolved Node,演进的基站),eNodeB为用户设备的接入提供无线资源。
HSS(Home Subscriber Server,归属用户服务器),用于永久性的存储用户签约数据。
PDN(Packet Data Network,分组数据网),为用户提供业务的网关。
演进的分组网的核心网E-Packet Core实现了更低的时延,并允许更多的无线系统接入,其包括如下网元:
MME(Mobility Management Entity,移动管理实体),是控制面功能实体,临时存储用户数据的服务器,负责管理和存储用户设备UE上下文(例如,用户标识、移动性管理状态和用户安全参数等),为用户分配临时标识,当UE驻留自身所管辖的跟踪区域内或需要对用户进行鉴权,处理MME和UE之间的非接入层消息,触发eNodeB进行寻呼等。
Serving GW(Serving Gateway,服务网关),是用户面实体,负荷用户面数据路由处理,终结处于空闲状态的UE的下行数据,管理和存储UE的SAE的承载上下文,例如IP承载业务参数和网关内部路由信息等。Serving GW是系统内部用户面的锚点,一个用户在一个时刻只能有一个Serving GW。
PDN GW(PDN Gatew,分组数据网网关),为负责UE接入PDN的网关,分配用户的IP地址,用户在同一时刻能接入多个PDN GW。
PCRF(Policy and Charging Rule Functionality,策略和计费规则功能实体),用于根据业务信息、签约信息以及运营商配置信息产生控制用户数据传输的Qos(Quality of Service,服务质量)规则以及计费规则。该功能实体页可以控制接入网承载的建立和释放。
参见图2,为本发明第一实施例提供的一种寻呼用户设备的方法的流程示 意图,在本发明实施例中,所述方法包括:
S201、在对空闲态的用户设备进行寻呼之前,移动管理实体MME确定所述用户设备上次访问的基站。
具体的,服务网关接收数据网关发送的下行数据包,下行数据包携带用户设备的标识。服务网关检测下行隧道的状态,如果下行隧道无效,表明用户设备为空闲态,服务网关无法将下行数据包转发给用户设备。服务网关将下行数据包进行缓存,向MME发送下行数据通知(Downlink Data Notification)消息。MME接收到下行数据通知消息后,向服务网关返回下行数据应答消息。MME需要寻呼空闲态的用户设备,MME在对用户设备进行寻呼之前,MME查询用户设备上次访问的基站,所述上次访问的基站为用户设备为连接态时最近一次访问的基站,连接态的用户设备切换基站时,通过信令消息将切换后的基站的基站标识上报给MME,MME存储连接态的用户设备最近一次访问的基站,MME可根据本地存储的用户设备的基站访问记录查询用户设备上一次访问的基站。
跟踪区域列表包含一个或者多个跟踪区域,跟踪区域由一个或多个基站组成,空闲状态的用户设备位于跟踪区域列表中的跟踪区域时,不需要发起跟踪区域更新请求。当用户设备移动到不属于跟踪区域列表中的跟踪区域时,向MME发起跟踪区域更新请求,跟踪区域更新请求携带用户设备当前所在的跟踪区域的标识和上一次访问的跟踪区域的标识,MME根据用户设备当前所在的跟踪区域的标识和上一次访问的跟踪区域的标识更新跟踪区域列表,向用户设备返回更新后的跟踪区域列表。MME存储跟踪区域和基站的映射表,可根据映射表查询跟踪区域对应的基站。
S202、所述MME确定所述用户设备上次访问的基站处于非过载状态。
具体的,用户设备上次访问的基站的负荷状态分为过载状态和非过载状态,用户设备上次访问的基站的负荷状态可以由MME根据基站的负荷参数的参数值来判断、或者由MME根据与基站间的链路参数的参数值来判断;或由基站自身进行判断,然后基站将非过载通知消息发送给MME,MME由非过载通知消息确定用户设备上次访问的基站处于非过载状态。
S203、所述MME向所述用户设备上次访问的基站发送包含所述用户设备的标识的寻呼消息。
具体的,用户设备位于上一次访问的基站所属的小区内的概率大。如果用户设备上次访问的基站处于非过载状态,MME向用户设备上次访问的基站发送携带用户设备的标识的寻呼消息。用户设备上次访问的基站接收到寻呼消息后,在所属的小区内寻呼用户设备。如果寻呼到用户设备,用户设备向MME发起服务请求流程,用户设备通过上次访问的基站向MME发送服务请求消息。MME接收到服务请求消息后建立下行隧道,用户设备由空闲态转为连接态,SGW通过建立的下行隧道将缓存的下行数据包发送给用户设备。这样MME能减少寻呼信令的发送,节省信令资源。
实施本发明的实施例,当MME需要寻呼用户设备时,确定用户设备上次访问的基站处于非过载状态,MME指示用户设备上次访问的基站在所属的小区内发起寻呼,用户设备如果在上次访问的基站的小区内,就能成功寻呼到用户设备,这样能有效的提高寻呼效率,减少寻呼信令的消耗。
参见图3,为本发明实施例提供的一种寻呼用户设备的方法的流程示意图,在本发明实施例中,所述方法包括:
S301、在对空闲态的用户设备进行寻呼之前,移动管理实体MME确定所述用户设备上次访问的基站。
具体的,在S301的具体过程可参照S201的描述,此处不再赘述。
S302、确定所述用户设备上次访问的基站的负荷状态。
具体的,用户设备上次访问的基站的负荷状态分为过载状态和非过载状态,用户设备上次访问的基站的负荷状态可以由MME根据基站的负荷参数的参数值来判断、或者由MME根据与基站间的链路参数的参数值来判断;或由基站自身进行判断,然后基站将非过载通知消息或过载通知消息发送给MME,MME根据过载通知消息或非过载通知消息来判断。如果MME确定用户设备上次访问的基站处于过载状态,执行S303或S305;如果MME确定用户设备上次访问的基站处于非过载状态,执行S304。
进一步的,所述MME确定所述用户设备上次访问的基站处于非过载状态包括:
所述MME监测所述用户设备上次访问的基站的负荷参数的参数值,若所述负荷参数的参数值不大于负荷参数阈值,确定所述用户设备上次访问的基站处于非过载状态;其中,所述负荷参数阈值小于所述用户设备上次访问的基站 的处理能力参数的最大值;或
所述MME监测与所述用户设备上次访问的基站间的链路参数的参数值,若所述链路参数的参数值大于链路参数阈值,确定所述用户设备上次访问的基站处于非过载状态;或
所述MME根据所述用户设备上次访问的基站上报的非过载通知消息确定所述用户设备上次访问的基站处于非过载状态。
具体的,基站确定用户设备上次访问的基站的负荷状态的具体过程可参照方法实施例二中的描述,此处不再赘述。
S303、所述MME向所述用户设备的跟踪区域列表对应的所有基站发送包含所述用户设备的标识的寻呼消息。
具体的,当用户设备上次访问的基站为过载状态时,MME如果首先指示用户设备上次访问的基站进行寻呼,而用户设备不在用户设备上次访问的基站的小区内,可能会导致用户设备上次访问的基站的负荷状态进一步恶化,无法正常提供服务。此时MME采用的寻呼策略是指示用户设备的跟踪区域列表对应的所有的基站发起寻呼,用户设备的跟踪区域列表对应的基站包括用户设备上次访问的基站。MME向跟踪区域列表对应的所有基站发送携带用户设备的标识的寻呼消息,寻呼消息用于指示基站在所属的小区内寻呼用户终端。空闲态的用户设备位于跟踪区域列表对应的基站的某个小区内,MME指示跟踪区域列表对应的所有基站发起寻呼,能成功寻呼到用户设备。
S304、所述MME向所述用户设备上次访问的基站发送包含所述用户设备的标识的寻呼消息。
具体的,S304的具体过程请参照S203的描述,此处不再赘述。
S305、对所述用户设备上报访问的基站执行流量控制操作。
具体的,MME确定用户设备上次访问的基站处于过载状态时,表明MME与用户设备上次访问的基站之间的链路性能变差,用户设备上次访问的基站的负荷变重,MME需要对用户设备上次访问的基站进行流量控制操作,以减轻用户设备上次访问的基站的业务处理压力,防止用户设备上次访问的基站无法提供服务。
示例性的,链路参数为用户数,链路参数阈值为1000,监测周期为10S,当前监测时刻t到来时,MME在当前监测时刻t监测与用户设备上次访问的 基站的用户数为1200,大于链路参数阈值1000,MME确定用户设备上次访问的基站处于过载状态,MME需要在t时刻至t+10S时刻的时间段内对用户设备上次访问的基站进行流量控制操作;在下一监测时刻t+10S到来时,MME在t+10S内监测到用户设备上次访问的基站的用户数为800,小于链路参数阈值1000,MME确定用户设备上次访问的基站处于非过载状态,MME在t+10S时刻至t+20S时刻内不对用户设备上次访问的基站进行流量控制;如果在t+10S时刻监测到用户设备上次访问的基站的用户数为1100,仍然大于链路参数阈值1000,MME确定用户设备上次访问的基站为过载状态,MME继续在t+10S时刻至t+20S时刻内对用户设备上次访问的基站进行流量控制。
进一步的,所述方法还包括:
当所述用户设备上次访问的基站的负荷参数的参数值大于第一参数阈值时,对所述用户设备上次访问的基站执行流量控制操作;在对所述用户设备上次访问的基站执行流量控制操作后,当所述用户设备上次访问的基站的负荷参数的参数值小于第二参数阈值时,取消对所述用户设备上次访问的基站的流量控制操作;其中,所述第二参数阈值小于第一参数阈值,所述第一参数阈值小于所述用户设备上次访问的基站的处理能力参数的最大值。
具体的,MME周期性的监测用户设备上次访问的基站的负荷参数的参数值,当在当前的监测时刻用户设备上次访问的基站的负荷参数的参数值大于第一参数阈值,在当前的监测周期内,MME对用户设备上次访问的基站执行流量控制操作,使用户设备上次访问的基站承载的流量减少,用户设备上次访问的基站相对应的负荷参数的参数值会减少;当下一个监测时刻到来时,用户设备上次访问的基站的负荷参数的参数值小于第二参数阈值时,MME取消对用户设备上次访问的基站的流量控制操作;如果下一监测时刻到来时,用户设备上次访问的基站的负荷参数的参数值仍然大于第一参数阈值,在当前的监测周期内继续对用户设备上次访问的基站执行流量控制操作。其中,第一参数阈值大于第二参数阈值,且第一参数阈值和第二参数阈值均小于所述用户设备上次访问的基站的处理能力参数的最大值。
示例性的,监测周期为10s,用户设备上次访问的基站的负荷参数为信令消息量,第一参数阈值720pps,第二参数阈值为540pps,用户设备上次访问的基站的处理能力参数的最大值为850pps,第二参数阈值<第一参数阈值< 用户设备上次访问的基站的处理能力参数的最大值。MME在当前监测时刻t0时刻监测用户设备上次访问的基站的信令消息量的参数值为800pps,大于第一参数阈值720pps,MME在t0时刻至t0+10s时刻的时间段执行对用户设备上次访问的基站的流量控制操作,目的是减少MME发往用户设备上次访问的基站的信令消息;在下一监测时刻t0+10s时刻监测用户设备上次访问的基站的信令消息量的参数值为500pps,小于第二参数阈值540pps,MME在t0+10s至t0+20s的时间段取消对用户设备上次访问的基站的流量控制操作。
S306、在预设时间内是否接收到所述用户设备上次访问的基站发送的服务请求消息。
具体的,MME指示用户设备上次访问的基站在所属的小区发起寻呼,如果用户设备不在用户设备上次访问的基站所属的小区内,用户设备上次访问的基站就不会接收到用户设备发起的用户触发服务请求流程的服务请求消息,用户设备上次访问的基站也不会将服务请求消息转发给MME,如果MME向用户设备上次访问的基站发送寻呼消息后预设时间内未接收到用户设备返回的服务请求消息,MME就认为用户设备上次访问的基站未寻呼到用户设备,执行S307,否则执行S309。预设时间可以根据通信系统的性能指标进行设置,本发明不作限制。
S307、确定对所述用户设备的寻呼失败。
具体的,确定用户设备上次访问的基站对用户设备寻呼失败,用户设备不在上次访问的基站的小区内。
S308、所述MME向所述用户设备的跟踪区域列表对应的所有基站发送包含所述用户设备的标识的寻呼消息。
S309、确定对所述用户设备的寻呼成功。
进一步,在本发明的一些实施例中,所述MME对所述用户设备上次访问的基站执行流量控制操作包括:
所述MME全部丢弃待发送给所述用户设备上次访问的基站的信令消息或寻呼消息;或
所述MME获取待发送给所述用户设备上次访问的基站的信令消息或寻呼消息的优先级,丢弃优先级最低的信令消息或寻呼消息;或者
所述MME随机丢弃部分待发送给所述用户设备上次访问的基站的信令 消息或寻呼消息。
具体的,上述步骤中的流程控制操作的具体过程可操作方法实施例二的描述,此处不再赘述。
进一步可选的,在本发明的实施例中,所述监测所述用户设备上次访问的基站的负荷参数的参数值之前,还包括:
所述MME获取所述用户设备上次访问的基站的处理能力参数的最大值,并根据所述处理能力参数的最大值配置所述负荷参数阈值、所述第一参数阈值和所述第二参数阈值。
具体的,用户设备上次访问的基站的处理能力参数的最大值表示用户设备上次访问的基站最大可承载的信令消息或寻呼消息量,基站的类型不同,其处理能力参数的最大值不相同,例如宏基站的处理能力参数的最大值大于微基站的处理能力参数的最大值,MME设定负荷参数阈值、第一参数阈值和第二参数阈值时,要求上述三种阈值均小于处理能力参数的最大值,且满足第一参数阈值大于第二参数阈值,这样为用户设备上次访问的基站预留部分资源,防止用户设备上次访问的基站无法提供服务。
其中,处理能力参数包括寻呼消息量或信令消息量,MME获取用户设备上次访问的基站的处理能力参数的最大值的方法可以是:用户设备上次访问的基站向MME上报自己的寻呼消息量或信令消息量的最大值,用户设备上次访问的基站的处理能力参数的最大值可以在S1建链请求消息(S1 Setup Request)中携带,也可以在其他基站和MME间的交互消息中携带。
需要说明的是,用户设备上次访问的基站的处理能力参数的最大值也可以在MME上配置,或者通过操作和维护中心(Operation and Maintenance,O&M)下发,例如:基于第一集中地基站标识配置或下发用户设备上次访问的基站的处理能力参数的最大值,其中,基站标识可以为eNodeB ID,基站网际协议(Internet Protocol,IP)地址,S1应用协议(S1Application Protocol,S1AP)本端实体标识等。
实施本发明的实施例,当MME需要寻呼用户设备时,确定用户设备上次访问的基站处于非过载状态,MME指示用户设备上次访问的基站在所属的小区内发起寻呼,用户设备如果在上次访问的基站的小区内,就能成功寻呼到用户设备,这样能有效的提高寻呼效率,减少寻呼信令的消耗。
参见图4,为本第三发明实施例提供的一种寻呼用户设备的方法的流程示意图,在本发明实施例中,所述方法包括:
S401、在对空闲态的用户设备进行寻呼之前,移动管理实体MME确定所述用户设备上次访问的基站。
具体的,S401的具体过程可参照S201的描述,此处不再赘述。
S402、所述MME确定所述用户设备上次访问的基站的类型属于预设基站类型。

用户设备上次访问的基站与MME通过S1接口建立链接时,用户设备上次访问的基站需要向MME发送S1建链请求消息,S1建链请求消息中携带表示用户设备上次访问的基站的基站类型的基站类型标识,MME通过S1建链请求消息获取用户设备上次访问的基站的基站类型。或者,操作维护中心维护有记录各个基站的基站类型的存储记录,操作维护中心将用户设备上次访问的基站的基站类型通知给MME。或者,MME本地配置用户设备上次访问的基站的基站类型,比如基于基站标识配置用户设备上次访问的基站的基站类型,所述基站标识可以为eNodeB ID,基站IP地址,S1AP本端实体标识等。
S403、所述MME向所述用户设备上次访问的基站发送包含所述用户设备的标识的寻呼消息。
具体的,用户设备上次访问的基站的处理能力相对较强,而且用户设备位于上一次访问的用户设备上次访问的基站所属的小区内的概率很大。如果用户设备上次访问的基站的基站类型为预设基站类型,MME向用户设备上次访问的基站发送携带用户设备的标识的寻呼消息,用户设备上次访问的基站接收到寻呼消息后,在所属的小区内寻呼用户设备,如果寻呼到用户设备,用户设备向MME触发服务请求流程,MME建立下行隧道,用户设备由空闲态转为连接态,MME通过建立的下行隧道将缓存的下行数据包发送给用户设备。这样MME能减少寻呼信令的发送,节省信令资源。
实施本发明的实施例,当MME需要寻呼用户设备时,判断用户设备上次访问的基站的基站类型,如果基站类型为预设基站类型,MME指示上次访问的基站在所属的小区内发起寻呼,用户设备如果在上次访问的基站的覆盖范围内,就能成功寻呼到用户设备,这样能有效的提高寻呼效率,减少寻呼信令的消耗。

具体的,上述步骤中的具体过程可参照方法实施例二的描述,此处不再赘述。
S506、所述MME向所述用户设备上次访问的基站发送包含所述用户设备的标识的寻呼消息。
具体的,用户设备上次访问的基站的处理能力相对较强,而且用户设备位于上一次访问的用户设备上次访问的基站所属的小区内的概率很大。如果用户设备上次访问的基站的基站类型为预设基站类型,MME向用户设备上次访问的基站发送携带用户设备的标识的寻呼消息,用户设备上次访问的基站接收到寻呼消息后,在所属的小区内寻呼用户设备,如果寻呼到用户设备,用户设备向MME触发服务请求流程,MME建立下行隧道,用户设备由空闲态转为连接态,MME通过建立的下行隧道将缓存的下行数据包发送给用户设备。这样MME能减少寻呼信令的发送,节省信令资源。
