Joint session admission control method under heterogeneous network convergence scene

Abstract

The invention discloses a joint session admission control method under a heterogeneous network convergence scene. The method comprises the following steps: (1) collecting bandwidth resources of wireless communication networks as a vector bandwidth resource library; (2) establishing a joint session admission control universal model for the vector bandwidth resource library according to two optimizing targets of minimizing session access cost and optimizing system load balance; and (3) solving the joint session admission control universal model by a manual intelligent method to give a joint session admission control scheme. The joint session admission control method under the heterogeneous network convergence scene disclosed by the invention converts the joint session admission control problem into a plurality of target optimization problems through modeling, namely, the user session access cost is taken as an optimizing target, while the system load balance performance is taken as the other optimizing system. The load balance target and the user session access cost target are better taken into consideration.

Description

Technical field [0001] The invention relates to a joint session admission control method in a heterogeneous network convergence scene, which solves the load balancing problem of each communication network, so as to weaken the unbalanced communication of user sessions distributed in the time domain (time) and spatial domain (spatial) The adverse effects of the system. Background technique [0002] At present, in the wireless communication network system, there will be both the fully mature second-generation (2G) mobile communication network, and the third-generation (3G) mobile communication network represented by WCDMA, CDMA2000 and TD-SCDMA, and 4G Network, as well as broadband wireless local area network / metropolitan area network (WLAN / WMAN) represented by IEEE802.11a / b / g, HiperLan / 2, WiMAX, due to the radio access technology (radio access technology, Different RATs result in different network management architectures and business support, thus forming a heterogeneous network ...

Problems solved by technology

The problem caused by this processing method is that although the utilization rate of the access bandwidth is high, when the number of sessions increases to a certain number, the session blocking rate increases accordingly, which reduces the user experience.
