寻呼消息的发送方法、接收方法、接入网设备及终端
相关申请的交叉引用
本申请主张在2020年4月23日在中国提交的中国专利申请号No.202010328088.5的优先权，其全部内容通过引用包含于此。
技术领域
本发明实施例涉及通信技术领域，尤其是指一种寻呼消息的发送方法、接收方法、接入网设备及终端。
背景技术
空口的寻呼可能由核心网触发或接入网触发。基站向终端发送的空口寻呼消息中携带寻呼原因，该寻呼原因用于指示寻呼终端的原因，如是因为有基于5G接入的语音通话(Voice over New Radio，VoNR)业务触发了寻呼终端。终端可以根据从空口收到的寻呼消息中携带的寻呼原因值，确定后继的行为，如是否响应寻呼。例如，终端是一个双卡终端，卡1正在玩游戏，此时，卡2收到一个寻呼消息，对应的寻呼原因为VoNR(即语音电话)，终端可能会选择响应卡2的寻呼消息；如果卡2收到一个寻呼消息，对应的寻呼原因为短信，终端可能会选择忽略卡2的寻呼消息，如等到卡1的游戏结束，才发起连接建立。
但是寻呼原因是新引入的特性，因此有些低版本的终端并不支持识别寻呼原因。而对于上述低版本的终端，空口寻呼消息中若携带寻呼原因，由于该部分终端无法识别该寻呼原因值，只能进行忽略，从而增加空口的开销。
发明内容
本发明实施例提供一种寻呼消息的发送方法、接收方法、接入网设备及终端，以解决现有技术中空口寻呼消息中均携带寻呼原因易造成资源浪费的问题。
为了解决上述技术问题，本发明实施例是这样实现的：一种寻呼消息的 发送方法，应用于第一接入网设备，包括：

在本发明实施例中，一方面，通过在接口寻呼消息中指示终端是否支持接收寻呼原因，能够实现向支持接收寻呼原因的终端发送携带寻呼原因的空口寻呼消息，向不支持接收寻呼原因的终端发送不携带寻呼原因的空口寻呼消息，避免资源浪费，提升资源利用率；另一方面，在空口寻呼消息中通过隐式方式携带寻呼原因，从而降低携带寻呼原因引入的开销问题。

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。
在本发明实施例中，“示例性的”或者“例如”等词用于表示作例子、例证或说明。本发明实施例中被描述为“示例性的”或者“例如”的任何实施例或设计方案不应被解释为比其它实施例或设计方案更优选或更具优势。确切而言，使用“示例性的”或者“例如”等词旨在以具体方式呈现相关概念。
下面结合附图介绍本发明的实施例。本发明实施例提供的寻呼消息的发送方法、寻呼消息的接收方法可以应用于无线通信系统中。该无线通信系统可以为采用第五代(5 th Generation，5G)系统，或者演进型长期演进(Evolved Long Term Evolution，eLTE)系统，或者后续演进通信系统。
本发明实施例提供的第一接入网设备、第二接入网设备可以为基站，该基站可以为通常所用的基站，也可以为演进型基站(evolved node base station，eNB)，还可以为5G系统中的网络侧设备(例如下一代基站(next generation node base station，gNB)或发送和接收点(transmission and reception point，TRP))或者小区cell等设备。其中，第一接入网设备为终端直接接入的接入网设备，例如基站；第二接入网设备为锚点接入网设备，例如锚点基站。
本发明实施例提供的终端可以为手机、平板电脑、笔记本电脑、超级移动个人计算机(Ultra-Mobile Personal Computer，UMPC)、上网本、可穿戴式设备(Wearable Device)、车载设备或者个人数字助理(Personal Digital Assistant，PDA)等。需要说明的是，在本发明实施例中并不限定终端的具体类型。本发明实施例中以LTE以及NR系统为例，然不限于此系统，本发明提供的技术方案可以应用于存在相同问题的其他系统。
如图1所示，本发明实施例提供一种寻呼消息的发送方法，应用于第一 接入网设备，包括：
步骤101，接收接口寻呼消息，所述接口寻呼消息中携带寻呼原因；
步骤102，若所述接口寻呼消息还携带用于指示终端支持接收寻呼原因的第一指示信息，在空口发送携带所述寻呼原因的空口寻呼消息。
本发明实施例提供的寻呼消息的发送方法能够避免终端不支持接收寻呼原因但空口寻呼消息中仍携带寻呼原因所造成的资源浪费。
作为一个可选实施例，所述方法还包括：
若所述接口寻呼消息不携带所述第一指示信息，在空口发送不携带所述寻呼原因的空口寻呼消息；
或者，
若所述接口寻呼消息还携带用于指示终端不支持接收寻呼原因的第二指示信息，在空口发送不携带所述寻呼原因的空口寻呼消息。
换言之，本发明实施例提供两种指示终端是否支持接收寻呼原因的方式：
方式一：通过是否携带第一指示信息，标识终端是否支持接收寻呼原因；即接口寻呼消息中携带第一指示信息，表示终端支持接收寻呼原因；接口寻呼消息中不携带第一指示信息，表示终端不支持接收寻呼原因。
方式二：通过携带第一指示信息指示终端支持接收寻呼原因，通过携带第二指示信息指示终端不支持接收寻呼原因。
本发明实施例通过接口寻呼消息指示终端是否支持接收寻呼原因，若指示终端不支持接收寻呼原因，则第一接入网设备在空口寻呼消息中不携带寻呼原因；若指示终端支持接收寻呼原因，则第一接入网设备在空口寻呼消息中携带寻呼原因。
本发明实施例中，空口的寻呼可能由核心网触发或接入网触发。在空口的寻呼由核心网触发的情况下，步骤101包括：
接收核心网设备发送的接口寻呼消息；
其中，在所述终端向所述核心网设备上报所述终端支持接收寻呼原因的情况下，所述接口寻呼消息携带所述第一指示信息。
如图2所示，核心网通过N2口(如果基站连接到5G核心网)或S1口(如果基站连接到第四代(4 th Generation，4G)核心网)给第一接入网设备 发送接口寻呼消息。接口寻呼消息中携带寻呼原因(paging cause)。
如果接口寻呼消息中还携带第一指示信息，则第一接入网设备接收到该接口寻呼消息后，触发空口寻呼消息的发送，该空口寻呼消息中携带对应的寻呼原因；如果接口寻呼消息中不携带第一指示信息或者接口寻呼消息中携带第二指示信息，触发空口寻呼消息的发送，该空口寻呼消息中不携带寻呼原因。
可选地，如图3所示，支持接收寻呼原因的终端，通过非接入层(Non-Access Stratum，NAS)能力上报过程，向核心网设备上报该终端支持接收空口寻呼原因。
在空口的寻呼由接入网触发的情况下，步骤101包括：
接收第二接入网设备发送的接口寻呼消息；
其中，在核心网设备发送的下行数据包的包头的第一特定域指示终端支持接收寻呼原因的情况下，所述接口寻呼消息携带所述第一指示信息；或者，在所述终端向所述第二接入网设备上报所述终端支持接收寻呼原因的情况下，所述接口寻呼消息携带所述第一指示信息。
如图4所示，第二接入网设备(存储了终端上下文的基站，即锚点基站)通过Xn口(如果第一接入网设备连接到5G无线接入网)或X2口(如果第一接入网设备连接到4G无线接入网)给第一接入网设备发送接口寻呼消息。接口寻呼消息中携带寻呼原因。例如，第二接入网设备接收核心网设备发送的下行数据包，该下行数据包的包头中的第二特定域用于指示寻呼原因。
可选地，第二接入网设备确定终端是否支持接收寻呼原因的方式包括：
方式一，根据核心网设备发送的下行数据包的包头的第一特定域确定；例如，第一特定域的第一取值指示终端支持接收寻呼原因，第一特定域的第二取值指示终端不支持接收寻呼原因。
方式二，如图5所示，支持接收寻呼原因的终端，通过接入层(Access Stratum，AS)能力上报过程，向第二接入网设备上报该终端支持接收空口寻呼原因。
第一接入网设备收到接口寻呼消息后，触发空口寻呼消息的发送，该空口寻呼消息中携带对应的寻呼原因；如果接口寻呼消息中不携带第一指示信 息或者接口寻呼消息中携带第二指示信息，触发空口寻呼消息的发送，该空口寻呼消息中不携带寻呼原因。
作为一个可选实施例，下行数据包的包头中的第一特定域和第二特定域可以不同，也可以相同。当第一特定域和第二特定域相同时，可通过特定域(即第一特定域或第二特定域)的不同取值来对应寻呼原因、终端是否支持接收寻呼原因。例如，特定域的长度为2比特，其取值分别为00，01，10，11；其中，00对应寻呼原因1，01对应寻呼原因2，10对应寻呼原因3，11对应终端不支持接收寻呼原因。
作为一个可选实施例，步骤101之后，所述方法还包括：
若所述接口寻呼消息不携带第一指示信息或者所述接口寻呼消息携带第二指示信息，判断所述第一接入网设备的空口是否拥塞；
在所述第一接入网设备的空口拥塞的情况下，根据所述接口寻呼消息携带的寻呼原因确定是否发送空口寻呼消息。
本发明实施例中如果终端不支持接收寻呼原因，但是接收寻呼消息中携带了寻呼原因，当基站空口拥塞时，基站可以预判如果以该寻呼原因寻呼终端，且终端响应了寻呼，那么，基站是否可以接纳终端；如果基站预判其不能接纳终端，则基站可以不发送空口寻呼消息。
例如，假设终端被寻呼，寻呼原因是短信，终端不支持接收空口寻呼原因。当基站收到接口寻呼消息时，其空口拥塞，判断如果寻呼消息发送给终端，然后终端响应寻呼(为了接收短信而请求接入基站)，其会拒绝终端接入。此时，基站可以直接不在空口发送此空口寻呼消息。
综上，本发明实施例通过在接口寻呼消息中指示终端是否支持接收寻呼原因，能够实现向支持接收寻呼原因的终端发送携带寻呼原因的空口寻呼消息，向不支持接收寻呼原因的终端发送不携带寻呼原因的空口寻呼消息，避免资源浪费，提升资源利用率；或者，寻呼原因被携带到第一接入网设备，有利于第一接入网设备根据自己的状况(如空口是否拥塞)，确定是否发送空口寻呼消息，提升寻呼效率。
如图6所示，本发明实施例还提供一种寻呼消息的接收方法，应用于终端，包括：
步骤601，接收空口寻呼消息及第三指示信息；
步骤602，在所述第三指示信息指示所述空口寻呼消息隐式携带寻呼原因或者所述第三指示信息指示当前小区支持发送寻呼原因情况下，根据所述空口寻呼消息和所述第三指示信息，确定寻呼原因。
本发明实施例中，一种实现方式中，第三指示信息用于指示所述空口寻呼消息隐式携带寻呼原因或者所述第三指示信息用于指示当前小区支持发送寻呼原因，也就是说，在空口寻呼消息隐式携带寻呼原因或当前小区支持发送寻呼原因的情况下，终端才能够接收到第三指示信息。例如，第三指示信息被定义为一个特定域，终端只要接收到该特定域，则表示所述空口寻呼消息隐式携带寻呼原因或者当前小区支持发送寻呼原因。
另一种实现方式中，第三指示信息用于指示所述空口寻呼消息是否隐式携带寻呼原因或者所述第三指示信息用于指示当前小区是否支持发送寻呼原因，也就是说，无论空口寻呼消息是否隐式携带寻呼原因或者无论当前小区是否支持发送寻呼原因，终端均能够接收到第三指示信息，终端需根据第三指示信息的具体内容(例如取值)来确定所述空口寻呼消息是否隐式携带寻呼原因或者当前小区是否支持发送寻呼原因。例如，第三指示信息为1比特，当该比特为“0”则表示空口寻呼消息不携带寻呼原因或者当前小区不支持发送寻呼原因；当该比特位“1”则表示空口寻呼消息隐式携带寻呼原因或者当前小区支持发送寻呼原因。
本发明实施例中当基站发送需要携带寻呼原因的空口寻呼消息时，部分寻呼原因可以显式携带，部分寻呼原因可以隐式携带。
但是，如果终端收到的空口寻呼消息中，未携带寻呼原因。那么就存在两种可能：
1.基站不支持发送寻呼原因，空口寻呼消息中未携带寻呼原因；
2.基站支持发送寻呼原因，空口寻呼消息中隐式携带了寻呼原因，即此时寻呼原因是隐式指示的原因。
为了解决上述问题，本发明实施例引入第三指示信息；即若终端接收到的空口寻呼消息不携带寻呼原因，但是终端接收到第三指示信息或者接收到第三指示信息指示所述空口寻呼消息隐式携带寻呼原因或指示当前小区支持 发送寻呼原因，此种情况认为终端收到寻呼原因，该寻呼原因对应空口寻呼消息隐式指示的寻呼原因；若终端接收到的空口寻呼消息不携带寻呼原因，且终端未接收到第三指示信息或接收到第三指示信息指示所述空口寻呼消息不携带寻呼原因或指示当前小区不支持发送寻呼原因，此种情况认为终端未收到寻呼原因，即网络未发送寻呼原因。
作为一个可选实施例，步骤602包括：
在所述空口寻呼消息未携带用于标识寻呼原因的目标域的情况下，根据所述第三指示信息，确定所述空口寻呼消息隐式指示的寻呼原因。若空口寻呼消息携带所述目标域，则所述空口寻呼消息显式携带寻呼原因。
其中，所述空口寻呼消息隐式指示的寻呼原因为：除所述目标域标识的寻呼原因之外的其他寻呼原因。
例如，假设支持两种寻呼原因：语音业务，其他业务。此时，可以在寻呼消息中，通过一个可选IE标识寻呼原因，例如：当该IE出现时，表示寻呼原因为：语音业务；当该IE不出现时，表示寻呼原因为：其他业务。
再例如，假设支持五种寻呼原因：原因1～5，用长度为2比特的IE标识。当该IE取值为00，01，10，11时，分别对应原因1～4；当该IE不出现时，对应原因5。
作为一个可选实施例，步骤601中接收第三指示信息，包括：
接收系统信息(系统信息为接入网设备广播)，所述系统信息中携带所述第三指示信息；
或者，
接收调度寻呼消息的下行控制信息(Downlink Control Information，DCI)(DCI为接入网设备发送)，所述下行控制信息中携带所述第三指示信息；作为一种实现，可以通过DCI中的短消息(short message)携带；可选地，DCI携带的第三指示信息用于指示DCI调度的寻呼消息是否隐式携带寻呼原因，或者，用于指示DCI调度的寻呼消息隐式携带寻呼原因。
或者，
接收非接入层NAS消息(NAS消息为核心网设备发送)，所述NAS消息中携带所述第三指示信息。
可选地，本发明的上述实施例中，所述NAS消息还用于向终端指示所述终端所在的跟踪区列表中的所有小区是否均支持发送寻呼原因，或者，用于向终端指示所述终端所在的跟踪区列表中的所有小区是否均不支持发送寻呼原因。
其中，跟踪区列表中包含至少一个跟踪区。
作为一个可选实施例，所述方法还包括：
终端将收到或确定出的所述寻呼原因上报至无线资源控制(Radio Resource Control，RRC)层或者RRC层的高层，以由所述RRC层或RRC层的高层进行处理。
综上，本发明实施例中在空口寻呼消息中通过隐式方式携带寻呼原因，终端根据空口寻呼消息和第三指示信息确定空口寻呼消息中隐式携带的寻呼原因，从而降低携带寻呼原因引入的开销问题。
如图7所示，本发明实施例还提供一种接入网设备700，该接入网设备为第一接入网设备，包括：
第一接收模块701，用于接收接口寻呼消息，所述接口寻呼消息中携带寻呼原因；
第一发送模块702，用于若所述接口寻呼消息还携带用于指示终端支持接收寻呼原因的第一指示信息，在空口发送携带所述寻呼原因的空口寻呼消息。
可选地，本发明的上述实施例中，所述接入网设备还包括：

或者，用于若所述接口寻呼消息还携带用于指示终端不支持接收寻呼原因的第二指示信息，在空口发送不携带所述寻呼原因的空口寻呼消息。
可选地，本发明的上述实施例中，所述第一接收模块包括：
