Problems solved by technology

If the SGW cache timer is set according to the above-mentioned traditional method of inheriting LTE, it can only be set according to the maximum paging response time (corresponding to the enhanced coverage level 2), because such a large cache timer is not required under other coverage levels device, so this will cause a waste of SGW resources

Abstract

The invention discloses a method, device and system for setting SGW cache time under NBIOT, and relates to the field of information communication. The method includes: receiving a downlink data acknowledgment message sent by the MME, wherein the downlink data acknowledgment message includes the coverage enhancement level or buffering time of the terminal; determining the buffering timer corresponding to the current downlink data of the terminal according to the coverage enhancement level or buffering time of the terminal ;Cache the downlink data within the cache time of the cache timer. The present invention can dynamically set the cache timer, and optimizes the resource usage of the SGW.

Description

technical field [0001] The present invention relates to the field of information communication, in particular to a method, device and system for setting SGW cache time under NBIOT. Background technique [0002] In the current 3GPP LTE (Long Term Evolution, long-term evolution) technology, when the SGW (ServingGateWay, serving gateway) is sending downlink data to the MME (Mobile Management Entity, mobile management entity), if the UE (terminal) can be paged to , the MME responds to the SGW, and the SGW waits for the MME to establish S1-U or S11-U before sending downlink data. Considering that it takes time for the UE to respond to the paging of the MME, the SGW sets a buffer timer after receiving the response from the MME, and the downlink data packet will be buffered by the SGW within the timer time. This timer is set as a global parameter on the SGW. [0003] At present, the NBIOT (Narrow Band Internet of Things, cellular-based narrowband Internet of Things) technology of...
