Problems solved by technology

[0006] Since the buffering duration T of the downlink data packet is for each UE, that is, all downlink data packets of the same UE use the same buffering duration T, such a setting of the buffering duration T will cause the gateway to buffer unnecessary services data, thereby reducing the cache usage efficiency of the gateway

Abstract

The embodiment of the invention provides a communication method and a communication device. The communication method comprises the following steps: receiving a notification message sent by a service gateway, wherein the notification message carries indication information of a downlink data packet to be sent to user equipment by the service gateway; under the condition of determining that the userequipment is unreachable, determining the cache duration of the downlink data packet according to the indication information; and sending an acknowledgement message to the service gateway, wherein theacknowledgement message carries the cache duration, so that the service gateway caches all downlink data packets to be sent to the user equipment corresponding to the indication information accordingto the cache duration. In the embodiment of the invention, the cache duration is determined according to the indication information of the downlink data packet, and the service gateway is informed ofthe cache duration, so the service gateway can cache different downlink data packets according to different cache durations, and the cache use efficiency of the service gateway can be improved.

Description

[0001] This application is a divisional application of an invention patent application with the application number 201580031902.4, the date of entry into the Chinese national phase is December 19, 2016, and the application name is "Communication Method and Communication Device". technical field [0002] The present invention relates to the communication field, and more specifically, to a communication method and a communication device. Background technique [0003] In an Evolved Packet System ("EPS" for short), if there is no data transmission for a long time, a user equipment (User Equipment, "UE" for short) will enter an idle state (Idle). In this state, when the EPS network receives a downlink data message or signaling from the user, the EPS network will initiate a service request process triggered by the network side. In this process, the Mobility Management Entity (MME) ) will initiate paging in the tracking area where the current user equipment is located, and the user...
