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。
本申请的说明书和权利要求书中的术语“包括”以及它的任何变形,意图在于覆盖不排他的包含,例如,包含了一系列步骤或单元的过程、方法、 系统、产品或设备不必限于清楚地列出的那些步骤或单元,而是可包括没有清楚地列出的或对于这些过程、方法、产品或设备固有的其它步骤或单元。此外,说明书以及权利要求中使用“和/或”表示所连接对象的至少其中之一,例如A和/或B,表示包含单独A,单独B,以及A和B都存在三种情况。
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。
在现有网络中,终端(比如支持多卡的终端,也称为多卡设备)存在接收到网络的寻呼但不响应寻呼的情况;比如,多卡终端配置了卡1和卡2。卡如USIM卡,可以是实体卡或电子卡。当多卡终端与卡2相关的第二网络进行业务时,可能会接收到关于卡1的第一网络的寻呼。但由于多卡设备的能力不能够同时与两个网络通信(如多卡设备的能力时单发双收或单发单收),在第二网络的业务更重要的情况下,可能放弃第一网络的业务数据。目前,为了节省寻呼资源,网络可以是在最后服务终端的小区中发起寻呼,当接收不到终端的响应时再逐步地扩大寻呼范围,直到为终端配置的跟踪区列表(TAI List)。然而,目前没有机制能让网络区分终端接收了寻呼但不响应,还是没有接收到寻呼。所以,由于缺乏多卡终端的收到寻呼但不响应信息,就会浪费第一网络的寻呼资源。但如果多卡终端返回寻呼响应,用户面资源就会恢复和开始数据传送,又会中断第二网络的业务。
为了保障第二网络的业务,且又避免浪费第一网络的寻呼资源,一种实现方案是:在多卡终端与第二网络的业务间隔,比如20ms~40ms中,多卡终端向第一网络响应寻呼,使得第一网络停止寻呼多卡终端,且多卡终端请求第一网络不传送数据和/或请求拒绝激活终端与第一网络的连接。第一网络可以继续缓存或丢弃关于多卡终端的数据并去激活多卡终端的连接。
此外,还要解决如下问题:
问题1:通过服务请求消息请求第一网络,但服务请求消息默认用于请求恢复协议数据单元(Protocol Data Unit,PDU)会话的用户面资源。当第一 网络缓存关于多卡终端(以下简称UE)的数据时,第一网络接收到UE的服务请求消息后,就会开始恢复缓存数据相关的PDU会话的用户面资源,也会开始传送控制面数据。
问题2:通过MICO(Mobile Initiated Connection Only)指示或PSM(Power Saving Mode)指示,可以在UE再次进入空闲(idle)态之前,让第一网络缓存后续到达的数据且不寻呼UE。但对引起本次寻呼使UE进入连接的数据,由于MICO还没有协商二不受MICO指示的控制。
问题3:除了不接收引起本次寻呼的数据,UE可能与第二网络进行长时间的业务(如游戏免打扰),长时间不会进入第一网络。则UE可以在与第二网络的业务间隔中与第一网络协商MICO或PSM。但现有的MICO是在服务请求(Service Request,SR)过程后,注册过程中协商,PSM是在服务请求过程后,TAU过程中协商。现有的MICO和PSM协商可能无法在UE与第二网络的业务间隔中完成。
问题4:为了尽量小地影响与第二网络的业务,UE与第一网络的交互的时间要越短越好。如何缩短UE与第一网络的交互时间也是本发明要解决的问题。
本发明实施例中,可选地,获取可以理解为从配置获得、接收、通过请求后接收、通过自学习获取、根据未收到的信息推导获取或者是根据接收的信息处理后获得,具体可根据实际需要确定,本发明实施例对此不作限定。比如当未收到设备发送的某个能力指示信息时可推导出该设备不支持该能力。
可选地,发送可以包含广播,系统消息中广播,响应请求后返回。

不难理解,上述指示不传送关于终端的数据为指示不传送触发所述寻呼 的关于终端的数据。一种实施方式中,第一网络网元(如RAN网元、或CN网元)仅丢弃或缓存触发本次寻呼的关于终端的数据。当后续再有关于终端的数据到达或等待时,第一网络网元依然可以寻呼终端,终端可以再次响应寻呼,确定是否传送所述数据并返回第一信息和/或第一消息。

请求丢弃触发寻呼的关于终端的控制面数据;
请求丢弃关于终端的所有控制面数据;
请求丢弃有效时间段内关于终端的所有控制面数据且所述有效时间段为丢弃关于终端的数据(如控制面数据)的有效时间信息指示的有效时间段;
请求丢弃触发寻呼的关于终端的用户面数据;
请求丢弃关于终端的所有用户面数据;
请求丢弃有效时间段内关于终端的所有用户面数据且所述有效时间段为丢弃关于终端的数据(如用户面数据)的有效时间信息指示的有效时间段。
不难理解,通过本实施例,当终端(如多卡终端)接收到第一网络的寻呼但确定不接收第一网络的关于终端的数据时,依然响应寻呼,但寻呼响应 后,指示不传送(如不接收)数据。这样第一网络可以不需要为终端的数据通道建立用户面资源,也不需要向终端传送数据,终端可以快速回到非连接态(如空闲态或非活跃态),第一网络也能收到终端的寻呼响应而停止寻呼,节省寻呼资源,避免寻呼资源、用户面资源分配、数据调度等无效的资源开销。
