Abstract

A method and apparatus for managing access network information are provided. The method includes: the dynamic access network information is obtained, and the current access network information list can be updated in real time according to the obtained dynamic access network information, so as to ensure that access network information obtained by a user terminal from the access network information list is latest information updated in real time. Thus, after the user terminal obtains the information, a process of scanning an access network to determine current availability information of the network can be omitted, so that the switching delay can be reduced, the switching efficiency can be improved, and the power consumption of the user terminal can be reduced, thereby improving the satisfaction degree of user experience.

First claim

What is claimed is:

1. A method for managing access network information, comprising:
obtaining dynamic access network information; and
updating a current access network information list according to the obtained dynamic access network information;
wherein obtaining the dynamic access network information comprises: obtaining the dynamic access network information from a user terminal, and/or obtaining the dynamic access network information from an access network management module;
wherein when obtaining the dynamic access network information comprises obtaining the dynamic access network information from the user terminal, the method comprises:
receiving the dynamic access network information sent by the user terminal, the dynamic access network information being dynamic access network information generated by the user terminal according to a connection result of connection thereof to an access network; and the user terminal connecting to the access network according to access network information obtained by sending an access network information obtaining request containing current position information about the user terminal or according to access network information obtained by self-detection;
wherein the dynamic access network information generated by the user terminal according to the connection result of connection thereof to the access network comprises:
when the connection result is that the user terminal is successfully connected to a corresponding access point and can be successfully connected to the internet, the generated dynamic access network information comprises: connection success information, user terminal position information and access point information; or
when the connection result is that the user terminal cannot find the corresponding access point or cannot access the corresponding access point or cannot be successfully connected to the internet after being connected to the corresponding access point, the generated dynamic access network information comprises connection failure information and access point information, and the connection failure information comprises a connection failure reason;
wherein updating the current access network information list according to the obtained dynamic access network information comprises:
when it is determined that the user terminal is successfully connected according to the obtained dynamic access network information, judging whether corresponding access point information exists in the current access network information list, and when the corresponding access point information does not exist in the current access network information list, adding the access point information to the access network information list; and
when it is determined that the user terminal fail to connect according to the obtained dynamic access network information, judging whether the corresponding access point information exists in the current access network information list, and when the corresponding access point information exists in the current access network information list, updating the access point according to the connection failure reason of the user terminal;
wherein updating the access point according to the connection failure reason of the user terminal comprises:
sending an access network information authentication request containing the access point information and position information of the user terminal to the access network management module;
receiving an authentication result obtained by authentication via the access network management module according to the access network information authentication request, wherein the authentication result includes the connection failure reason obtained by authentication; judging whether the connection failure reason obtained by authentication conforms to a failure fed back by the user terminal according to the authentication result, and when the failure reasons are conform, updating the access point;
or,
updating the access point after receiving dynamic access network information, including the same failure reason, fed back by at least one of other user terminals.

2. The method for managing access network information according to claim 1 , wherein updating the access point comprises:
when the failure reason is that the corresponding access point cannot be found or it cannot access the corresponding access point, setting the access point to be unavailable;
when the failure reason is that it cannot be successfully connected to the internet after being connected to the corresponding access point, re-setting the priority of the access point;
or
calculating the availability of the access point by using a pre-set optimization algorithm, when the calculated availability is smaller than a pre-set threshold value, setting the access point to be unavailable, and when the calculated availability is greater than the pre-set threshold value, setting the access point to be available.

3. The method for managing access network information according to claim 1 , wherein when obtaining the dynamic access network information comprises obtaining the dynamic access network information from the access network management module, the dynamic access network information comprises corresponding access point information and access point change information, the access point change information comprises at least one of position change information, identification change information, unavailable identification information and priority change information.

4. The method for managing access network information according to claim 3 , wherein updating the current access network information list according to the obtained dynamic access network information comprises:
judging whether corresponding access point information exists in the current access network information list according to the obtained dynamic access network information, in the case of existence,
when the access point information comprises the position change information of the access point, updating position information of the corresponding access point in the access network information list;
when the access point information comprises the identification change information of the access point, updating identification information of the corresponding access point in the access network information list;
when the access point information comprises the unavailable identification information, setting the corresponding access point in the access network information list to be unavailable;
when the access point information comprises the priority change information, updating the priority of the corresponding access point in the access network information list;
and in the case of inexistence,
when the access point information comprises the unavailable identification information, adding the corresponding access point to the access network information list, recording the unavailability thereof, or carrying out no processing; if the access point information comprises the position change information of the access point, adding the corresponding access point to the access network information list, and recording latest position information thereof;
when the access point information comprises the identification change information of the access point, adding the corresponding access point to the access network information list, and recording latest identification information thereof; and
when the access point information comprises the priority change information, adding the corresponding access point to the access network information list, and recording latest priority thereof.

5. The method for managing access network information according to claim 1 , wherein after the current access network information list is updated according to the obtained dynamic access network information, the method
