Description

一种寻呼消息发送方法及设备 技术领域
本发明涉及通信技术领域，尤其涉及一种寻呼消息发送方法及设备。
背景技术
在长期演进(Long Term Evolution，LTE)网络中，为了降低用户设备的功耗或者为了节省LTE网络的无线资源，用户设备可以在数据业务传输结束后便释放该用户设备与网络侧建立的无线连接链路。
在用户设备释放无线连接链路后，若无线网络中出现对该用户设备的下行数据或者下行信令，无线网络中的网元，如移动性管理实体(Mobility Management Entity，MME)，则需要向该用户设备所在的跟踪区(Tracking Area，TA)中的基站发送寻呼消息，以找到该用户设备，并向该用户设备传输上述下行数据或者下行信令。
但是，随着寻呼消息的增多，逐一处理大量的寻呼消息会加剧对MME的中央处理器(Central Processing Unit，CPU)的占用，并且传输大量的寻呼消息会加剧MME与基站之间的S1接口的信令负荷。
针对上述问题，现有技术提出了一种可以流控制传输协议(Stream Control Transmission Protocal，SCTP)聚合寻呼(Aggregate Paging)技术。SCTP聚合寻呼技术可以将多个寻呼消息在SCTP协议层打包成一个SCTP数据包，然后向基站下发该SCTP数据包。这样便可以减少逐一处理大量寻呼消息，对MME的CPU的占用，并可以降低S1接口的信令负荷。
但是存在的问题是：对多个寻呼消息进行寻呼聚合，会存在聚合时延，这样会影响部分优先级较高的用户设备的业务体验。

本发明实施例提供的寻呼消息发送方法及设备可以应用于LTE网络中，当MME开启聚合寻呼功能后，对用户设备寻呼的过程中。
以下通过具体实施例，对本发明提供的寻呼消息发送方法及设备进行详细说明：
实施例1
本发明实施例提供一种寻呼消息发送方法，应用于移动性管理实体(Mobility Management Entity，MME)，如图1所示，包括：
S101、MME接收服务网关(Serving Gateway，SGW)发送的下行数据通知(Downlink Data Notification，DDN)消息。
其中，DDN消息中携带有用户设备的标识，DDN消息用于指示MME向用户设备的跟踪区列表(Tracking Area List，TA List)中的基站发送寻呼消息。
当网络侧出现对一用户设备的下行数据或者下行信令，且该用户设备未与网络侧建立无线连接链路时，SGW可以向MME发送DDN消息，指示MME向该用户设备的TA List中的基站发送寻呼消息。其中，本发明实施例中的基站可以为LTE中的NodeB或eNB或e-NodeB。其中，一个TA list包含1～16个跟踪区(Tracking Area，TA)。MME可以为每一个用户设备分配一个TA list，并将分配给用户设备的TA list发送给该用户设备，由该用户设备保存其TA list。
TA是LTE系统为用户设备的位置管理设立的概念，TA功能与3G系统的位置区(Location Area，LA)和路由区(Routing Area，RA)类似。通过TA信息核心网设备(如MME)能够获知处于空闲态的用户设备的位置，并且在有数据业务需求时，对该用户设备进行寻呼。
当寻呼信令较多时，MME会开启聚合寻呼功能，本发明实施例针对MME已经开启聚合寻呼功能的情况下实施。
S102、MME在开启聚合寻呼功能后，根据DDN消息，确定用户设备的优先级是否高于预设等级。
示例性的，在本发明实施例的一种应用场景中，DDN消息中携带有高优先级寻呼(High Priority Paging，HPP)指示，HPP指示用于指示用户设备的优先级高于预设等级。
MME在接收到携带有HPP指示的DDN消息后，则可以确定用户设备的优先级高于预设等级，则可以直接向该用户设备的TA List中的基站发送寻呼消息。
其中，HPP指示可以为SGW接收到MME发送的聚合寻呼指示后，添加至DDN消息的，MME可以在开启聚合寻呼功能后，向SGW发送聚合寻呼指示。
在本发明实施例的第二种应用场景中，DDN消息中未携带有HPP指示。
在第二种应用场景中，MME可以在接收到DDN消息后，根据DDN消息携带的用户设备的标识，获得用户设备的服务质量(Quality of Service，QoS)信息，然后根据用户设备的QoS信息，确定用户设备的优先级是否高于预设等级。
其中，用户设备的QoS信息包括：QoS等级标识(QoS Class Identifier，QCI)以及分配和保持优先权(Allocation/Retension priority，ARP)信息。
S103、若用户设备的优先级高于预设等级，MME则直接向基站发送寻呼消息。
其中，当用户设备的优先级高于预设等级，MME则不会对相应的寻呼消息进行聚合寻呼，而是直接向该用户设备的TA List中的基站发送寻呼消息。
本发明的实施例提供的寻呼消息发送方法，MME接收SGW发送的DDN消息，DDN消息中携带有用户设备的标识，DDN消息用于指示MME向用户设备的TA List中的基站发送寻呼消息；在开启聚合寻呼功能后，根据DDN消息，确定用户设备的优先级是否高于 预设等级；若用户设备的优先级高于预设等级，MME则直接向基站发送寻呼消息。
通过本方案，MME可以在用户设备的优先级高于预设等级时，直接向基站发送寻呼消息，不需要对该寻呼消息进行聚合寻呼，因此不会存在聚合时延，从而及时发送高优先级用户设备的寻呼消息，可以保证高优先级用户设备的业务体验。
实施例2
本发明实施例提供一种寻呼消息发送方法，应用于SGW，如图2所示，该寻呼消息发送方法包括：
S201、若SGW接收到MME发送的聚合寻呼指示，SGW在接收到下行报文后，获得接收下行报文的用户设备的QoS信息。
其中，聚合寻呼指示为MME开启聚合寻呼功能后，发送给SGW的。聚合寻呼指示用于表明MME将对寻呼消息进行聚合寻呼。
SGW在获知MME已开启聚合寻呼功能，将对寻呼消息进行聚合寻呼时；为了避免MME对所有寻呼消息均进行聚合寻呼，而影响部分优先级较高的用户设备的业务体验，可以在接收到下行报文后，获得接收下行报文的用户设备的QoS信息，然后根据QoS信息确定用户设备的优先级是否高于预设等级；并于用户设备的优先级高于预设等级时，向MME发送携带有HPP指示的DDN消息，以指示所述MME向用户设备的TA List中的基站直接发送寻呼消息，不需要进行聚合寻呼。
S202、若SGW根据用户设备QoS信息确定用户设备的优先级高于预设等级，则向MME发送携带有HPP指示的DDN消息。
其中，DDN消息用于指示MME向用户设备的TA List中的基站发送寻呼消息，HPP指示用于指示用户设备的优先级高于预设等级。
用户设备优先级可以通过用户在SGW实体中数据相应承载对应的Qos信息中的QCI参数来标定。
本发明的实施例提供的寻呼消息发送方法，SGW可以在接收到 MME发送的聚合寻呼指示后，若接收到下行报文，获得接收下行报文的用户设备的QoS信息；若SGW根据用户设备QoS信息确定用户设备的优先级高于预设等级，则向MME发送携带有HPP指示的DDN消息。
通过本方案，SGW可以在用户设备的优先级高于预设等级时，向MME发送携带有HPP指示的DDN消息，以指示MME直接向基站发送寻呼消息，不需要对该寻呼消息进行聚合寻呼，因此不会存在聚合时延，从而及时发送高优先级用户设备的寻呼消息，可以保证高优先级用户设备的业务体验。

S303、SGW根据用户设备QoS信息确定用户设备的优先级是否高于预设等级。
需要说明的是，SGW根据用户设备QoS信息确定用户设备的优先级是否高于预设等级的具体方法可以参考上述实施例中的相关描述，本实施例这里不再赘述。
SGW在获知MME已开启聚合寻呼功能，将对寻呼消息进行聚合寻呼时；为了避免MME对所有寻呼消息均进行聚合寻呼，而影响部分优先级较高的用户设备的业务体验，可以在接收到下行报文后，确定用户设备的优先级是否高于预设等级；并于用户设备的优先级高于预设等级时，向MME发送携带有HPP指示的DDN消息， 以指示MME向用户设备的TA List中的基站直接发送寻呼消息，不需要进行聚合寻呼。
S304、若用户设备的优先级高于预设等级，SGW则向MME发送携带有HPP指示的DDN消息。
其中，DDN消息用于指示MME向所述用户设备的TA List中的基站发送寻呼消息，HPP指示用于指示用户设备的优先级高于预设等级。
进一步的，若SGW确定用户设备的优先级不高于预设等级，则可以向MME发送未携带有HPP指示的DDN消息。
S305、MME根据HPP指示，确定用户设备的优先级高于预设等级。
MME在接收到携带有HPP指示的DDN消息后，则可以确定用户设备的优先级高于预设等级。
