Abstract: A method for preventing abuse of an Authentication Vector (AV) and a system and apparatus for implementing the method are provided. Access network information of a non-3rd Generation Partnership Project (3GPP) access network where a user resides is bound to an AV of the user, so that when the user accesses an Evolved Packet System (EPS) through the non-3GPP access network, even if an entity in the non-3GPP access network is breached, or an Evolved Packet Data Gateway (ePDG) connected to an untrusted non-3GPP access network is breached, the stolen AV cannot be applied to other non-3GPP access networks by an attacker.
Abstract translation: 提供了防止认证向量（AV）的滥用的方法以及用于实现该方法的系统和装置。 用户驻留的非第三代合作伙伴计划（3GPP）接入网络的接入网络信息被绑定到用户的AV，使得当用户通过非3GPP接入网络访问演进分组系统（EPS）时， 即使违反非3GPP接入网络中的实体，或者违反连接到非信任非3GPP接入网络的演进分组数据网关（ePDG），则被盗AV不能通过以下方式应用于其他非3GPP接入网络 攻击者

Abstract: Embodiments provide an MTC device communication method, device, and system. A second network element receives, a query message sent by a first network element after the first network element identifies that a type of a received short message is a preset-type short message. The query message comprises an identifier of a receiver of the short message and an identifier of a sender of the short message. The second network element checks whether the sender is authorized to send the preset-type short message to the receiver. The second network element sends a message to the first network element indicating whether or not to send the short message to the receiver.
