Description
Technical field
The present invention relates to the communications fields, more particularly, to communication means and communication device.
Background technique
In evolved packet system (Evolved Packet System, referred to as " EPS "), if do not counted for a long time
According to transmission, user equipment (User Equipment, referred to as " UE ") can enter Idle state (Idle).In this state, when
When EPS network has received the data message or signaling of user's downlink, EPS network can initiate network side triggering service request stream
Journey, mobility management entity (Mobility Management Entity, referred to as " MME ") can be used currently in the process
Initiate paging in tracing area where the equipment of family, user equipment can in response to MME paging and be transferred to connected state (Connected)
Receive data or signaling.
But the interim interruption or UE due to wireless signal enable power savings mode (Power saving mode, letter
Referred to as " PSM "), the electricity-saving functions such as macrocyclic discontinuous reception (Discontinuous Reception, referred to as " DRX "),
Will lead to UE can not timely respond to the paging of network.Service application will constantly retransmit data at this time, to increase core net
The load and paging expense of member.
To avoid the problem, MME can indicating service gateway (Serving Gateway, referred to as " S-GW ") caching delay
The downlink data packet of tolerance service, when UE up to when the data of caching are sent to UE again.MME can be based on access point name
Caching to determine downlink data packet is locally configured in the signing information of (Access Point Name, referred to as " APN "), UE
Duration T, and inform S-GW.S-GW caches the downlink data packet of the UE according to the instruction of MME in duration T.When fixed
When device T time-out after, the discardable data packet cached of S-GW.
Since the caching duration T of downlink data packet is for each UE, i.e., all lower line numbers of the same UE
Identical caching duration T is used according to packet, it is unnecessary that the setting of such caching duration T will will lead to gateway caches
Business datum, to reduce the caching service efficiency of gateway.
