[0005] However, the QoS parameter weight of the current service determined by this heterogeneous network switching method only reflects a subjective requirement of the user for each QoS parameter, and it is very likely that the current status of each network to be evaluated cannot meet the subjective requirements of the terminal. , the final result of the handover judgment is no handover, which increases the probability of handover failure, resulting in the terminal still running services in the original network and unable to enjoy better service quality of other networks

[0019] see figure 1 , which is a flow chart of the first embodiment of a method for heterogeneous network handover in the present invention, including the following steps:

[0020] Step 101: Determine the first weight of the parameters in the QoS parameter set, the first weight is the subjective weight of user demand, and determine the second weight of the parameters in the QoS parameter set according to the current QoS parameter value of the network to be evaluated;

[0021] Step 102: Perform coincidence fusion of the first weight and the second weight to determine a third weight of parameters in the QoS parameter set;

[0022] Step 103: Determine a target network according to the third weight, and perform network switching.

[0023] It can be seen from the above embodiments of the present invention that when determining the QoS parameter weight of the current service, in addition to considering a subjective requirement of the terminal for each QoS parameter and obtaining th...

Abstract

The invention discloses a method and a device for switching heterogeneous networks. The method comprises the following steps: determining first weights of parameters in a QoS parameter set, wherein the first weights are subjective weights required by a user; determining second weights of the parameters in the QoS parameter set according to the current QoS parameter value of networks to be evaluated; carrying out fusion of coincidence degree on the first weights and the second weights, and determining third weights of the parameters in the QoS parameter set; and determining a target network according to the third weights so as to switch the networks. According to the embodiment of the invention, when the heterogeneous networks are switched, the method and the device increase the possibility for finding the target network and improve the success ratio of switching so as to enable the terminal to enjoy better service quality of other networks and further improve the satisfaction of the user.

Description

technical field [0001] The present invention relates to the technical field of wireless mobile communication, in particular to a method and device for heterogeneous network switching. Background technique [0002] At present, different types of wireless access technologies are developing rapidly, because these access technologies have their own characteristics and suitable application occasions. Therefore, a network composed of different access technologies is called a heterogeneous network. Heterogeneous networks are different in terms of bandwidth, mobility support, effective coverage, QoS (Quality of Service, quality of service), billing rates, security, and the like. [0003] Heterogeneous network switching means that the terminal crosses the existing network boundary and switches services from one network to another network. After the network switching is completed, the switched network is used to manage the current services. In order to make better use of network tec...
