Abstract

The invention discloses a link monitoring method and apparatus for monitoring the state of a transmission link on Long Term Evolution wireless local area network (LTE-WLAN) aggregation in the transmission on LTE-WLAN aggregation, such that the method and the apparatus can discover and address congestion of the transmission link on LTE-WLAN aggregation, prevent the further deterioration of the properties of the transmission link on LTE-WLAN aggregation, and increases the transmission quality of the transmission link on LTE-WLAN aggregation. The invention also provides a link monitoring method which includes the following steps: a base station determining the need for transmitting a probe packet to a user device through the WLAN, wherein the probe packet is intended for probing whether the link for the communication between the base station and the user device via the WLAN is normal; and the base station transmitting the probe packet to the user device through the WLAN.

Description

technical field [0001] The present invention relates to the technical field of communications, in particular to a link monitoring method and device. Background technique [0002] With the growth of user demands and the development of communication technologies, more and more wireless communication technologies and related networks have emerged, for example, 2G / 3G / 4G mobile communication technologies and networks that can provide wide coverage, and wireless communication technologies that can provide hotspot coverage. Local area network (Wireless LAN, WLAN) network. Therefore, a large number of scenarios where different communication networks coexist, such as scenarios where 2G / 3G / 4G networks and WLANs coexist, also appear. The third generation partnership project (3rd Generation Partnership Project, 3GPP) has developed a new solution, that is, the Long Term Evolution (LTE) WLAN Aggregation (LTE WLAN Aggregation, hereinafter referred to as LWA) technology, which can realize ...
