1. A method comprising:
- receiving, by a control plane network element, a delay instruction from a mobility management network element, wherein the delay instruction instructs the control plane network element to delay sending a downlink data notification (DDN) message;
receiving, by a user plane network element, a downlink data packet for a user equipment (UE);
sending, by the user plane network element, an event report message to the control plane network element, wherein the event report message comprises a reported event, and wherein the reported event notifies the control plane network element that the downlink data packet matches no bearer;
determining, by the control plane network element, that the UE is registered in the mobility management network element; and
sending, by the control plane network element, the DDN message to the mobility management network element when the control plane network element has not received routing information of a base station from the mobility management network element within a first time period, wherein the routing information of the base station identifies a bearer.

Abstract
A downlink data notification message sending method and apparatus are disclosed. In an embodiment a method includes receiving, by a user plane network element, a downlink data packet to be sent to a user equipment (UE) and sending, by the user plane network element, an event report message to a control plane network element, wherein the event report message includes a reported event, and wherein the reported event notifies the control plane network element that the downlink data packet matches no bearer.

11. A communications system comprising:
-
a user plane network element; and a control plane network element, wherein the user plane network element is configured to; receive a downlink data packet for a user equipment (UE), and send an event report message to the control plane network element, wherein the event report message comprises a reported event, and wherein the reported event notifies the control plane network element that the downlink data packet matches no bearer, and wherein the control plane network element is configured to; receive a delay instruction from a mobility management network element, wherein the delay instruction instructs the control plane network element to delay sending a downlink data notification (DDN) message, receive the event report message from the user plane network element, determine that the UE is registered in the mobility management network element, and send the DDN message to the mobility management network element when the control plane network element has not received routing information of a base station from the mobility management network element within a first time period, wherein the routing information of the base station identifies a bearer. - View Dependent Claims (12, 13)
