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.
Claims13
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.

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.
