Embodiment Construction

[0036] The specific implementation manners of the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0037] figure 1 A schematic diagram of a typical service flow distribution scenario in the overlapping coverage area of ​​multiple networks under the fusion of heterogeneous networks in the present invention is shown. The network side includes the core network CN, the multimedia server MMS connected to the core network CN, and in the overlapping coverage area of ​​multiple networks, there are three different wireless access networks connected to the core network CN, which are respectively marked as wireless access networks. Access 1 (abbreviated as RAN 1 ), Radio Access Network 2 (abbreviated as RAN 2 ) and Radio Access Network 3 (abbreviated as RAN 3 ), where RAN 1 、...

Abstract

The invention provides a system and a method for traffic flow distribution under heterogeneous network fusion. The system comprises radio resource management (RRM) equipment (11, 12, ..., and 1M) in a radio access network (1, 2, ..., and M), a combined radio resource management (CRRM) equipment (21) in a core network (CN), and terminal equipment (31,32, ..., and 3N). In the method, the changing condition of the radio environment in the network is considered; from the perspective of the average end-to-end time delay and packet loss and the optimum utilization of the whole resource of the system, the resource in each network and among the terminals is coordinated; under the premise of minimizing the average end-to-end time delay and packet loss, the decision of the service flow distributionof the performance of the optimal system is solved; and on the premise of giving consideration to the limited power of the terminal equipment, the average end-to-end time delay and packet loss of thewhole system is reduced, and the experience satisfaction degree of a user is improved.

Description

technical field [0001] The present invention relates to the technical field of wireless communication, in particular to a system and method for service flow distribution under heterogeneous network integration. Background technique [0002] With the rapid development of various wireless communication technologies, various wireless communication technologies have emerged, such as GSM and UMTS for cellular coverage; WiFi and WiMAX for user hotspot coverage; Bluetooth and Zigbee for short-distance communication. Countries have begun to study new ultra-3G and 4G network architectures, and heterogeneity will be an important feature of future wireless communication networks. In addition, with the continuous advancement of microelectronics technology, large-scale integrated circuit technology, chip technology and operating system software technology, new changes will inevitably occur in wireless communication terminal equipment, and intelligent wireless communication equipment with...
