Abstract

The invention discloses a communication system and a communication method based on an IASA (inter access system anchor) load balancing device, belonging to the technical field of communication. In the invention, the load balancing device carries out centralized perception to all access networks in the heterogeneous convergence communication field to control switching between a 3GPP (3rd generation partnership project) access system and other access systems; and after the network is accessed to a user, the IASA load balancing device monitors and scans load conditions of all access network gateways in a real-time manner, and calculates the average load rate of all gateways and network load factor. If the network load exceeds the threshold value, partial users switch to other networks with light loads; and if the network load does not exceed the threshold value, and the current gateway load of the user is overweight, the user switches to other gateways of the current network. By adopting the invention, the load balance of the access network and the gateway can be realized, and the network performance problems such as congestion, call drop and time delay extension caused by heavy network or gateway load are solved.

Description

technical field

[0001] The present invention relates to the field of heterogeneous converged communication, in particular to the third generation mobile communication partnership project (the 3 rd Generation Partnership Project, referred to as 3GPP) Communication in the long-term evolution of the mobile communication system (Long Time Evolution, LTE) / system architecture evolution (System Architecture Evolution, SAE). Background technique

[0002] With the continuous development of communication technology, various new broadband wireless access technologies continue to emerge, posing a challenge to the 3G system. In order to ensure the competitiveness of 3GPP within 10 years or even 10 years later, 3GPP launched the long-term evolution research project (Long Term Evolution, LTE) of wireless access network in 2004. In addition, 3GPP also carried out related work on system architecture evolution, and It is defined as SAE (System Architecture Evolution, System Architecture E...
