Problems solved by technology

However, in the actual implementation process, the information provided by these data is often incomplete, and the data are missing.
This situation caused ANDSF to be unable to provide WLAN switching information to the user's mobile client foreground
[0006] 2. Linked data is inaccurate
The coverage of cell base stations can reach several square kilometers, which is much larger than the coverage of Wifi hotspots. This association matching relationship cannot truly reflect the actual association situation. This situation will also lead to the lack of authenticity of the information and may also lead to users complaint
[0008] 4. The associated data is accurate, and the WiFi hotspot signal exists, but the WiFi hotspot is faulty, resulting in the risk of access failure
In some cases, the Wifi hotspot was working normally, but a sudden failure caused it to fail, or the signal drifted unstable
In these cases, if ANDSF background data provides automatic WiFi hotspot discovery function, it will also lead to user complaints
[0009] It can be seen that due to the existence of the above-mentioned existing technical defects, the physical quality of the existing WLAN handover is difficult to be guaranteed, which increases the risk of user complaints due to misjudgment of information

Embodiment 1

[0033] like figure 1 As shown, the present invention provides a WiFi hotspot discovery method, comprising the following steps:

[0034] S1. Clients such as smart phones send the base station information (Cell Id) of the cell where they are located to the ANDSF server;

[0035] S2. The ANDSF server feeds back policy information to the client according to the received base station information, and the policy information includes the information of the WiFi hotspot associated with the base station of the cell where the client is located; the association of the WiFi hotspot with the base station indicates that the base station is controlled by the WiFi hotspot covered by the signal;

[0036] S3. If the policy information indicates that there is no WiFi hotspot associated with the base station of the cell where the client is located, turn on the WiFi switch of the client such as the smart phone from the background, and scan the WiFi hotspot to find a new WiFi hotspot. When perfor...

Embodiment 2

[0043] like figure 2 As shown, the present invention also provides a method for switching from a non-WiFi network (such as a 2G or 3G network) to a WiFi network, comprising the following steps:

[0044] S1', utilizing the WiFi hotspot discovery method described in embodiment one to automatically discover WiFi hotspots;

[0045] S2', after successfully discovering the WiFi hotspot, authenticate the client, and perform WiFi network access from the discovered WiFi hotspot after passing the authentication.

[0046] As can be seen from the above embodiments, the method of the second embodiment of the present invention applies the reliable WiFi hotspot discovery method of the first embodiment, which provides a reliable guarantee for the physical quality of WLAN handover, and reduces user errors caused by misjudgment of information. Risk of Complaints.

Abstract

The invention relates to the technical field of wireless communication, and discloses a wireless fidelity (WiFi) hotspot finding method and a network switching method. Reliable guarantee is supplied to physical quality of a wireless local area network (WLAN) by judging whether a cell base station where a client is positioned is covered by a WiFi hotspot signal and judging whether the cell base station meets a switching condition; and therefore, the risk of complaints of users caused by mis-judgment of information is reduced.

Description

technical field [0001] The invention relates to the technical field of wireless communication, in particular to a WiFi hotspot discovery method and a network switching method. Background technique [0002] With the rapid growth of domestic mobile communication operators, especially China Mobile's GSM network data service users and business volume, the scale of GSM network has risen sharply. A large amount of investment has been used to increase GSM equipment and increase network capacity. However, the increase in capacity is difficult to keep up with the growth rate of services, resulting in heavy-duty operation of the 2G network, and it is difficult to guarantee user perception. On the other hand, with the widespread use of mobile communication applications such as Tencent QQ and WeChat, services based on small data blocks and long TCP connections have increasingly become the main source of pressure on the carrier frequency of mobile base stations. Especially office buildi...
