specific Embodiment approach 1

[0028] Specific implementation mode 1: A heterogeneous network selection system based on service type weight distinction in this implementation mode specifically includes:

[0029] Network discovery and static information collection module 1, candidate network QoS parameter value collection module 2 and candidate network evaluation and selection module 3;

[0030] The network discovery and static information collection module 1 discovers neighboring RANs through MIHF and collects static information of neighboring RANs;

[0031]The QoS parameter value collection module 2 of the candidate network detects network discovery successively and the static information collection module 1 collects the RSS of the adjacent static information RAN, incorporates the RSS of the detected adjacent static information RAN into the ranks of candidate networks, and collects the current QoS parameter values ​​of candidate network ranks;

[0032] The candidate network evaluation and selection module...

specific Embodiment approach 2

[0037] Specific embodiment 2: The difference between this embodiment and specific embodiment 1 is that the MIHF used by the network discovery and static information collection module 1 for the entire network configuration is determined by the mobile terminal as the current radio access network (RadioAccess Network, RAN) When communicating in ), the neighbor RAN is found and the static information of the neighbor RAN is collected, and the static information of the neighbor RAN is collected and stored in the local database; wherein, the handover mode of the mobile terminal decision refers to the selection of the entire network and the handover decision by the mobile The terminal initiates and determines the final target network, which is the leading behavior of the terminal, not determined by the network;

[0038] The candidate network QoS parameter value collection module 2 is used for when the mobile terminal detects that the signal strength of the wireless static information o...

specific Embodiment approach 3

[0040] Embodiment 3: This embodiment differs from Embodiment 1 or Embodiment 2 in that: a heterogeneous network selection method based on service type weight distinction includes the following steps:

[0041] Step 1. Using the network-wide configuration MIHF in the network discovery and static information collection module 1, when the mobile terminal decides to communicate in the current radio access network (RadioAccessNetwork, RAN), discover neighboring RANs and collect static information of neighboring RANs , and collect the static information of the adjacent RAN and store it in the local database; where MIHF assumes that the entire network has been configured with the Media Independent Handover Function (MIHF) of IEEE802.21;

[0042] Step 2: When the mobile terminal detects that the wireless static information signal strength (RadioSignalStrength, RSS) of the current RAN drops to the handover threshold by using the QoS parameter value acquisition module of the candidate net...

Abstract

The invention discloses a heterogeneous network selection system and method based on business type weight differentiation, relates to the field of heterogeneous network selection, and aims to solve the problems that the lowest QoS (quality of service) threshold values of business requirements are not different, and network utilization rate is reduced and the quality of service is weakened as loads between networks are unbalanced. The heterogeneous network selection system comprises a network discovery and static information collection module (1), a candidate network QoS parameter value acquisition module (2) and a candidate network evaluation and selection module (3). The method particularly includes the steps: firstly, finding adjacent RANs (radio access networks), collecting static information of the adjacent RANs and storing the static information in a database by an MIHF (media independent handover function); secondly, bringing the detected adjacent RANs positioned on a communication threshold value into a candidate network rank, and collecting QoS parameter values of the candidate network rank; thirdly, selecting a candidate network with the largest ideal approximation value to serve as a target network.

Description

technical field [0001] The invention relates to a heterogeneous network selection system and method based on business type weight distinction. Background technique [0002] With the globalization of the telecommunications industry and the rapid development of the Internet, communication systems emerge in endlessly, forming a variety of independent networks, such as cellular mobile communication systems (2G, 3G), short-distance access systems (WLAN, Bluetooth, ultra-wideband UWB system), WiMAX, satellite communication, broadcasting system (such as DAB, DVB), stratosphere, etc. The network structure of these networks is independent of each other, and each network has its own advantages. For example, the network communication systems of 2G and 3G are mainly based on voice communication and support data communication; while WLAN, WiMAX and other networks are mainly based on data services. . With the gradual shrinking of voice communication services, the development of wireless...
