Description
Technical field
The present invention relates to the communication technology, the network selecting method under especially a kind of Double coverage and system, dual-mode terminal.
Background technology
Mobile network and WLAN (wireless local area network) (Wireless Local Area Network, hereinafter to be referred as: WLAN) two kinds of wireless networks can be realized wireless data access.At present, because WLAN is operated in 2.4G or 5.8G frequency range, (Access Point, the scope left and right hereinafter to be referred as: coverage AP) at tens meters to 100 meters are obviously different from mobile network single base station hundreds of rice to the service radius of several kms to single access point.But for mobile network, WLAN but can provide speed of surfing the Internet at a high speed, for example, WLAN based on IEEE802.11g standard is theoretical supports the speed of surfing the Internet of the highest 54Mb/s, and unit cost of surfing the net is lower.Compare with WLAN, although the passable coverage of single base station is larger in mobile network, it provides the speed of wireless data relatively low, the 3G network putting it into commercial operation even current, it provides the speed of wireless data also well below current WLAN, and unit cost of surfing the net is higher.
Different characteristics based on above-mentioned two kinds of wireless networks, when operator builds mobile network at cloth, for the more region of wireless data application, carry out mobile network and WLAN covering simultaneously, by WLAN, shunt mobile network's data traffic, reach the effect that reduces mobile network data load, promotes user radio application perception.But, due to WLAN limited coverage area, and network operation stability is poor with respect to mobile network, the problem that therefore can exist the region how simultaneously to cover at two wireless networks to carry out optimum wireless network selection, thereby can make full use of the different advantages of two wireless networks, to user, provide optimum wireless Internet access to experience to greatest extent.
For the problems referred to above, industry is generally selected access to mobile network or WLAN in the following way at present:
The one, user covers according to mobile network and WLAN has or not, signal is strong and weak or individual preference is manually selected access to mobile network or WLAN on dual-mode terminal.In which, by user oneself, manually select the wireless network of access to need user's active operation, but, because a lot of users do not have professional knowledge, therefore be difficult to determine the online better effects if of which kind of wireless network, the wireless network of access can only be blindly selected, the different advantages of two wireless networks cannot be made full use of;
The 2nd, under mobile network and wlan network Double coverage, force WLAN preferentially to select.Although which avoids user manually to select wireless network, but, because its choice criteria of following is, no matter whether WLAN signal is better than mobile network signals, dual-mode terminal all preferably accesses WLAN, like this, can cause the signal between the congested and different user of wlan network to disturb, and now may occur that mobile network's wireless Internet access effect is better than the situation that WLAN does not have user's choice for use mobile network.Therefore, the reasonable utilization of Internet resources or user awareness all do not obtain optimum realization.
The deficiency of selecting access to mobile network or WLAN to exist for fear of above-mentioned two kinds of modes, in prior art, proposed following automatic network selection method, made dual-mode terminal automatic network selection under mobile network and WLAN Double coverage: the intensity to WLAN signal judges; If WLAN signal is more by force, preferred WLAN; Otherwise, automatic selecting mobile network.
In realizing process of the present invention, inventor's discovery, at least there is following problem in the automatic network selection method of above-mentioned prior art:
For wireless network, owing to there is air interference between different user, therefore, it is high that the intensity of wireless signal by force might not access rate, that is to say, and the wireless network that user selection signal is stronger, it uses perception to get well.Therefore, prior art only according to one of the power of wireless signal because usually selecting the wireless network of access to have certain contingency, cannot make full use of two kinds of wireless network resource, and may cause the signal between the congested and different user of wlan network to disturb, affect the normal use of user to wireless network traffic, reduced the service quality of wireless network traffic.

In response to this random number, be greater than R/2, dual-mode terminal is definite switches to mobile network by WLAN.
According to another example of the present invention and unrestricted, when dual-mode terminal is arranged in WLAN, the value of int can be obtained the number of times variation of weighted value and change along with dual-mode terminal, therefore, dual-mode terminal can increase the once value of this int when each weighted value is not less than default weighted value threshold value, and the value of this int is increased gradually; Until dual-mode terminal is switched to after mobile network by WLAN, the value of int is reverted to initial value.
For example, if the initial value of int is 0, dual-mode terminal is measured for the first time the weighted value value getting and is more than or equal to while presetting weighted value threshold value in WLAN, the value of int is 0, as dual-mode terminal is now determined and is not switched to mobile network by random algorithm, measuring the weighted value value getting is more than or equal to while presetting weighted value threshold value, the value of int is increased to R/4, the like, be increased to for the third time R/2, once dual-mode terminal is switched to mobile network, the value of int sets to 0 again.Here the weighted value value getting is more than or equal to the number of times of default weighted value threshold value and can under actual operating environment, sets and can change with the value of each int.
