Abstract: Embodiments of the present invention disclose a method, a network element, and a system for determining a target RAT. The method includes: receiving, by an access network element, access control information of a UE that is sent by a mobility management network element, where the access control information includes an identity of a PLMN and a radio access technology RAT allowed and/or a RAT not allowed by the PLMN; and determining, by the access network element, a target RAT for the UE according to the access control information. The present invention can be applied to a shared network environment.

Abstract: An IP address allocation method and a device are provided, so as to resolve a technical problem that an IP address conflict occurs when a control plane device and a user plane device allocate an IP address for one UE at the same time. When receiving a session establishment request message, a control plane network device may determine whether a first user plane network device is capable of allocating an IP address for a terminal device. If the first user plane network device is capable of allocating the IP address for the terminal device, the control plane network device may send an address allocation indication to the first user plane network device.

Abstract: Embodiments of the invention relate to communications field, in particular, to a downlink data notification message sending method, and apparatus. The method is: receiving, a delay instruction sent by a mobility management network element, which is used to instruct a control plane network element to delay sending a DDN message; receiving, an event report message sent by a user plane network element, where the event report message includes a reported event, and the reported event is used to notify the control plane network element that a downlink data packet sent to UE matches no bearer; determining, that the UE is registered in the mobility management network element; and if the control plane network element has not received, within a first time period, routing information of a base station, sending, the DDN message to the mobility management network element when the first time period expires.

Abstract: Embodiments relate to a network selection method and an apparatus. The method comprises: after receiving an access request message from a UE, a first core network device may send, to the UE, information about a dedicated second core network device corresponding to the UE, thereby ensuring that the UE can be attached to the dedicated second core network device according to the information about the dedicated second core network device, increasing selection accuracy when a core network device is selected for the user terminal, and avoiding occurrence of an access failure of the user terminal to the greatest extent.

Abstract: The present invention provides a method, a subscriber server and a mobility management entity for determining a serving node of a short message service. After receiving a location update request sent by an MME, an HSS/HLR determines services subscribed to by a subscriber. When determining that the subscriber has not subscribed to a CS domain service or there is only an SMS service in CS domain services subscribed to by the subscriber, the HSS/HLR registers the MME as a serving node that provides the SMS service for the subscriber.

Abstract: The present invention relates to a method, a device, and a system for processing a request for closed subscriber group subscription data. A closed subscriber group subscriber server receives a request sent by a mobility management network element. The request includes an identifier of the mobility management network element and an identifier of a user equipment is used for requesting closed subscriber group subscription data of the user equipment. If the closed subscriber group subscription data of the user equipment does not exist, the closed subscriber group subscriber server stores the identifier of the mobility management network element and the identifier of the user equipment.

Abstract: A service processing method and related devices are disclosed. The method includes: receiving, by a mobility management entity (MME), an access request message sent by a user equipment; obtaining, by the MME, indication information; and if the MME has been registered as a short message serving node and it is determined, according to the indication information, that the MME is no longer used as the short message serving node, sending, by the MME, a notification to a home subscriber server (HSS) so that the HSS cancels registration of the MME as the short message serving node.
Abstract translation: 公开了一种服务处理方法及相关装置。 该方法包括：由移动性管理实体（MME）接收由用户设备发送的接入请求消息; 由MME获取指示信息; 并且如果MME已经被注册为短消息服务节点，并且根据指示信息确定MME不再用作短消息服务节点，则由MME向本地用户发送通知 服务器（HSS），使得HSS取消作为短消息服务节点的MME的注册。
