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

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.

9. A control plane network element comprising:
-
a network interface; and a processor configured to; receive, by using the network interface, a delay instruction sent by a mobility management network element, wherein the delay instruction is used to instruct the control plane network element to delay sending a downlink data notification (DDN) message; receive, by using the network interface, an event report message sent by a user plane network element, wherein the event report message comprises a reported event, and the reported event is used to notify the control plane network element that a downlink data packet sent to user equipment (UE) matches no bearer; determine that the UE is registered in the mobility management network element; and when the control plane network element has not received, within a first time period, routing information of a base station sent by the mobility management network element, send the DDN message to the mobility management network element by using the network interface when the first time period expires, wherein the routing information of the base station is used to identify a bearer. - View Dependent Claims (10, 11, 12, 13, 14, 15, 16)

17. A non-transitory computer-readable storage medium comprising instructions which, when executed by a processor of a control plane network element, cause the processor to:
-
receive a delay instruction sent by a mobility management network element, wherein the delay instruction is used to instruct the control plane network element to delay sending a downlink data notification (DDN) message; receive an event report message sent by a user plane network element, wherein the event report message comprises a reported event, and the reported event is used to notify the control plane network element that a downlink data packet sent to user equipment (UE) matches no bearer; determine that the UE is registered in the mobility management network element; and when routing information of a base station sent by the mobility management network element is not received within a first time period, send, the DDN message to the mobility management network element when the first time period expires, wherein the routing information of the base station is used to identify a bearer. - View Dependent Claims (18)
