Abstract

The embodiment of the invention provides a load balancing method and system based on an LWIP architecture, and the method comprises the steps: obtaining the signal-to-interference-and-noise ratio of user equipment at a current moment, and calculating the qualified rate of the signal-to-interference-and-noise ratio according to the signal-to-interference-and-noise ratio; obtaining a channel utilization rate and a time delay parameter of a cell to which the user equipment belongs at the current moment, and calculating to obtain a multi-parameter joint influence threshold value according to the signal to interference plus noise ratio qualification rate, the channel utilization rate and the time delay parameter; and calculating to obtain a preset dynamic threshold according to the multi-parameter joint influence threshold and an initial fixed threshold, judging that the cell to which the user equipment belongs currently is in an overload state according to the preset dynamic threshold, andswitching the user equipment to an adjacent cell if a switching condition meets a preset condition. According to the method and the system provided by the embodiment of the invention, proper networkconfiguration and management are provided, the load states of the current overload cell and the candidate target cell can be estimated, and the switching of the UE is decided, so that the load can beeffectively distributed.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a load balancing method and system based on LWIP architecture. Background technique [0002] Today, with the explosive growth of global data traffic, load balancing is an issue that needs to be considered in any network architecture. Therefore, LWIP (LTE WLAN Radio Level Integration with IPsec Tunnel) also faces some load balancing problems. In the growth of data traffic, the proportion of mobile data volume is becoming more and more important. User mobility is a very important characteristic attribute. [0003] The structure of LWIP is very different from that of LWA. LWA's distribution strategy mostly performs data distribution or aggregation at the PDCP layer, while LWIP data performs data distribution and aggregation at its custom LAL layer. At the same time, because LWIP has no support for reordering , so LTE and WLAN cannot be transmitted separately and then...
