Problems solved by technology

Many network selection algorithms currently appearing have their own shortcomings. For example, the SAW algorithm has a simple process and only simply weights the parameter values ​​​​and their weights, but it cannot fully and accurately describe the various preferences of users; the TOPSIS algorithm also has simple features. , so it is widely used, but the consideration of business needs is limited, and there is a certain sort of abnormality; some others use a specific network architecture to propose an improved TOPSIS algorithm, and consider a variety of parameter attributes, but the system defaults to the user only Owning a multi-mode terminal only considers the terminal mobility when the terminal is roaming, and does not consider the user mobility, that is, the user's terminal selection among multiple single-mode / multi-mode terminals owned by the user, and does not consider the Take into account the various needs of the business

Embodiment 1

[0046] Embodiment 1: Based on the above-mentioned enhanced mobility management system, the network / terminal intelligent selection method of the present invention, such as figure 2 As shown in , the specific implementation process is as follows:

[0047] Step 1: Signal detection, the system will monitor the network in real time and measure the signal strength of the network. For a wired network, judge its signal strength SS. When SS>0, it means that the wired network is available; for a wireless network, judge its wireless signal strength RSS. Different wireless networks have different thresholds. When RSS>Threshold(threshold value), it is judged that the wireless network is available.

[0048]Step 2: According to the available networks judged in step 1, get a list of candidate networks. If the candidate network is less than or equal to 1, the network does not need to be selected and ends automatically; if the number of candidate networks is greater than 1, start collecting i...

Abstract

The invention relates to a network terminal selection method and a device in a heterogeneous network. The method selects the most suitable network to be accessed through collecting network information, user information, terminal information and service information of usable candidate networks, and selects the most suitable terminal in the selected network to execute the switching of the terminal or the switching of the network and the terminal. The invention changes emphasis on personal mobility from previous terminal mobility, enables a user to connect with a plurality of single mode/multiple mode terminals, innovatively considers a user terminal selection proposal and realizes terminal intelligent switching at the same time of network selection. Simultaneously, in order to enable the network selection to satisfy the demands of users and services to the maximum, the invention introduces a plurality of parameters in the aspect of networks, terminals, users and services, and uses a simplified intelligent network terminal selection method to enable a network selection mechanism to be more intelligent and effective.

Description

technical field [0001] The invention relates to a network terminal selection method and device in a heterogeneous network. Background technique [0002] With the rapid development of various communication technologies, the future heterogeneous network environment will integrate a variety of different wireless access technologies, such as 2G (GSM), 2.5G (GPRS), 3G (UMTS), WLAN, WiMAX, PAN, Fixed network, satellite communication, etc., because these different access technologies develop at different speeds, and most technologies evolve independently, and each has different types of terminals. Nowadays, heterogeneous networks tend to converge, and access networks with different characteristics and different operators coexist. Therefore, the mobility management technology of users between heterogeneous networks has attracted much attention. In previous technical research, it was assumed that the user only has one multi-mode terminal, which has multiple network interfaces to sup...
