A Joint Session Admission Control Method in Heterogeneous Network Convergence Scenario

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 fusion scenario, which solves the load balancing problem of each communication network and weakens the unbalanced distribution of user sessions in the time domain (in time) and air domain (in space) for communication. adverse effects on the system. Background technique [0002] At present, in the wireless communication network system, there are not only the second-generation (2G) mobile communication network with fully mature technology, but also the third-generation (3G) mobile communication network represented by WCDMA, CDMA2000 and TD-SCDMA, 4G network, as well as broadband wireless local area network / city area network (WLAN / WMAN) represented by IEEE802.11a / b / g, HiperLan / 2, and WiMAX. Due to the wireless access technology (radio access technology, RAT) lead to different network management structures 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.
