Description

Method, device and system for realizing wireless network access

Technical Field

The present invention relates to the field of communications technologies, and in particular, to a method, an apparatus, and a system for implementing wireless network access.

Background

With the explosive development of communication technology and data service, the service and signaling load of hot spot areas of wireless cellular networks are heavy, and the resources are seriously insufficient; for this reason, a currently commonly adopted mode is to deploy a Wireless Local Area network Access Point (WLAN AP) in a hot spot Area for shunting a cellular network data service and reducing the cellular network service and signaling load.

However, although most mobile terminals support the access of the wireless cellular network, the power consumption of the mobile terminals is greatly increased due to the limited power of the mobile terminals and the continuous scanning of the WLAN network by the mobile terminals. In this case, if the WLAN network auto-scan function of the mobile terminal is turned off, it cannot automatically receive the WLAN network notification even if the mobile terminal is in an area covered by the WLAN network; at this time, if a data service is initiated, since a user does not know whether a current area is covered by a WLAN network, the user often does not first manually open a WLAN network scanning function to try to search for the WLAN network, but directly selects to use a wireless cellular network to access the data service, which may result in that although some data service hot spot areas have deployed WLAN APs, the user does not know which areas are covered by the WLAN network actually, so the actual utilization rate of the WLAN network is low, and it is difficult to achieve the goal of offloading the data service of the cellular network hot spot areas through the WLAN network access points, thereby causing the traffic and signaling load of the cellular network to be still high.

A. the method comprises the steps that a mobile terminal periodically or when data service is initiated detects surrounding cellular networks and WLAN networks, if cellular network cells and WLAN APs are detected, AP coverage exists in the coverage of the cellular network cells, the cellular network cells and the WLAN APs are considered to have a relationship, a relationship list of the cellular network cells and the WLAN APs is generated according to a detection result, and then the relationship list of the cellular network cells and the WLAN APs is uploaded to network side equipment periodically or when a cellular network data service request is initiated; when the mobile terminal initiates a cellular network data service request, firstly detecting whether a stored cellular network cell and WLAN AP relation list is updated after network equipment is uploaded successfully last time; if the cellular network cell and WLAN AP relation list exists, uploading the updated cellular network cell and WLAN AP relation list to network side equipment through private messages when a cellular network data service request is initiated, or periodically uploading the updated cellular network cell and WLAN AP relation list to the network side equipment, so that the network side equipment can acquire the updated cellular network cell and WLAN AP relation list; the method comprises the steps that network side equipment receives a relation list of a cellular network cell and a WLAN AP uploaded by a mobile terminal, and the relation list records the corresponding relation of the cellular network cell and the WLAN AP; after receiving a cellular network data service request initiated by a mobile terminal, network side equipment queries the relation list according to a cellular network cell where the mobile terminal is currently located, so that whether a WLAN network exists in the coverage area of the cellular network cell where the mobile terminal is currently located can be determined;

B. the method comprises the steps that a mobile terminal periodically or when data service is initiated detects surrounding cellular networks and WLAN networks, if cellular network cells and WLAN APs are detected, AP coverage exists in the coverage of the cellular network cells, the cellular network cells and the WLAN APs are considered to have a relationship, a relationship list of the cellular network cells and the WLAN APs is generated according to a detection result, and then the relationship list of the cellular network cells and the WLAN APs is uploaded to a remote server periodically or when a cellular network data service request is initiated; when the mobile terminal initiates a cellular network data service request, firstly detecting whether a stored cellular network cell and WLAN AP relation list is updated after network equipment is uploaded successfully last time; if the cellular network cell and WLAN AP relation list exists, when a cellular network data service request is initiated, uploading the updated cellular network cell and WLAN AP relation list to a remote server through an FTP protocol, or periodically uploading the updated cellular network cell and WLAN AP relation list to the remote server, so that the network side equipment can acquire the updated cellular network cell and WLAN AP relation list from the remote server; the method comprises the steps that network side equipment acquires a relation list of a cellular network cell and a WLAN AP uploaded by a mobile terminal from a remote server, wherein the relation list records the corresponding relation of the cellular network cell and the WLAN AP; after receiving a cellular network data service request initiated by a mobile terminal, network side equipment queries the relation list according to a cellular network cell where the mobile terminal is currently located, so that whether a WLAN network exists in the coverage area of the cellular network cell where the mobile terminal is currently located can be determined;

C. the method comprises the steps that a user manually configures a relation list of a cellular network cell and a WLAN AP on network side equipment, and after the network side equipment receives a cellular network data service request initiated by a mobile terminal, the relation list is inquired according to the cellular network cell where the mobile terminal is located currently, so that whether the WLAN network exists in the coverage area of the cellular network cell where the mobile terminal is located currently can be determined.

It should be noted that the network side device or the remote server may periodically receive the relationship list uploaded by the mobile terminal, or may receive the relationship list while receiving the cellular network data service, which is not specifically limited in this embodiment;

D. after network side equipment receives a cellular network data service request initiated by a mobile terminal, acquiring a cellular network cell where the mobile terminal is currently located, inquiring a local preset relation list according to the cellular network cell where the mobile terminal is currently located, and if a corresponding WLAN AP can be found according to the cellular network cell, determining whether a WLAN network exists in the coverage area of the cellular network cell where the mobile terminal is currently located; and the corresponding relation between the cellular network cell and the WLAN AP is recorded in the local preset relation list.

It should be noted that the remote server in this embodiment is mainly configured to receive a relationship list between a cellular network cell and a WLAN AP, which is uploaded by a mobile terminal, and send the relationship list to the network side device when the network side device needs the relationship list, so as to reduce system overhead of the mobile terminal and the network side device; usually, for example, a File Transfer Protocol (FTP) server, etc., but persons of ordinary skill in the art also easily understand that the remote server in this embodiment may also be another server in the prior art, and details thereof are not described herein.

Step 120: when a WLAN network exists in the coverage area of the cellular network cell where the mobile terminal is currently located, the network side equipment can judge whether to shunt through the WLAN network according to a preset shunting strategy; if so, go to step 130; otherwise, accessing the data service through the existing standard cellular network data service access flow, and ending the flow;

in the practical application process, when the network side equipment determines that the WLAN network exists in the coverage area of the cellular network cell where the mobile terminal is currently located, the network side equipment can judge whether the data service request needs to be shunted through the WLAN network at the moment through a shunting strategy in the prior art; for example: presetting a flow threshold value, and when determining that a WLAN network exists, firstly pre-estimating whether the flow of the current data service request exceeds the preset threshold value, if so, indicating that the flow needs to be shunted through the WLAN network; if not, indicating that the shunting is not needed to be carried out through the WLAN network; of course, it is easily understood by those skilled in the art that whether offloading needs to be performed through the WLAN network may also be determined through other manners, which is not specifically limited in this embodiment and will not be described herein again.

It should be noted that, in the present embodiment, accessing to the cellular network access data service through the standard cellular network data service access flow is similar to the existing flow, and details of the present embodiment are not described herein again.

Step 130: the network side equipment acquires an AP list which is allowed to be accessed in the coverage area of the cellular network cell where the mobile terminal is located at present, and informs the mobile terminal of the AP list;

specifically, when the offloading needs to be performed through the WLAN network, the network side device communicates with all WLAN controller nodes (ACs) that have established connection, and sends an obtained or locally preset relationship list between a cellular network cell and a WLAN AP to each AC, so that the AC determines an AP list that is allowed to be accessed within a cell coverage area where the mobile terminal is currently located; after the AC receives the relationship list, the AC judges the load, interference state, availability state or whether the AP can be identified of all the APs in the relationship list, and determines the AP with the load exceeding a preset threshold or the interference exceeding the preset threshold, or the AP with the unavailable state or the AP which cannot be identified by the AC as the AP which is not allowed to be accessed; then, the AC filters all the APs which are not allowed to be accessed to obtain an AP list which is allowed to be accessed; of course, it is easily understood by those skilled in the art that after the AC receives the relationship list, the AP list allowed to be accessed may also be determined in other existing manners, and details are not repeated herein;

after sending the relationship list to the AC, the network side device receives a feedback message sent by the AC, where the feedback message carries at least one parameter of the AP identifier not allowed to be accessed, the AP list allowed to be accessed, or the AP list not allowed to be accessed;

after receiving feedback messages sent by all ACs, the network side equipment analyzes at least one parameter of the AP identification which is not allowed to be accessed, the AP list which is allowed to be accessed or the AP list which is not allowed to be accessed from the feedback messages and generates the AP list which is allowed to be accessed; then, the AP list allowing access is added in a cellular network data service request response message, and the mobile terminal is informed of the AP list allowing access; or, the network side device sends a private message containing the allowed access AP list to the mobile terminal through a cellular network data link, so as to notify the mobile terminal of the allowed access AP list; of course, it is easily understood by those skilled in the art that the mobile terminal may also be notified of the list of APs allowed to access through other manners, which is not specifically limited in this embodiment and will not be described herein again.

Step 140: and the mobile terminal receives the AP list allowed to be accessed and carries out association operation with each AP in the AP list allowed to be accessed in sequence.

Specifically, when the mobile terminal receives an access-allowed AP list sent by a network side device, the access-allowed AP list is extracted from a received response message or private message, and a connection is sequentially established with each AP in the access-allowed AP list, and an attempt is made to access the WLAN network through the AP.

Step 150: if the mobile terminal can not be successfully associated with each AP in the AP list which allows access, the cellular network data service request is reinitiated, a data service channel is reestablished to be accessed to the cellular network through a cellular network data service access process, the data service is accessed, and the process is ended; and if the mobile terminal is successfully associated with any AP in the list of the APs allowed to be accessed, accessing the WLAN network to access the data service by using the AP.

If the mobile terminal cannot be successfully associated with all the APs, judging whether the cellular network data service link is still communicated, if not, re-initiating the cellular network data service request to rebuild a 3GPP data service channel without re-triggering the cellular network data service request, and ending the process; if the mobile terminal succeeds with any AP, indicating that the mobile terminal can access the WLAN network through the AP, the mobile terminal does not continue to attempt to associate with other APs, but uses the AP to access the WLAN network and access data services.

In addition, a second embodiment of the present invention also provides a method for implementing wireless network access, as shown in fig. 2, the method is similar to the basic operation steps of the method in the foregoing embodiment, except that the method further includes:

step 160: after the mobile terminal is successfully associated with any AP, acquiring authentication information output from the outside and sending the authentication information to a WLAN network side, and accessing the WLAN network to access data services by using the AP after WLAN network authentication is completed; if the authentication fails, the cellular network data service request is reinitiated to rebuild the 3GPP data service channel without re-triggering the cellular network data service request again, and the process is ended; specifically, after the mobile terminal is successfully associated with any AP, the mobile terminal may acquire authentication information manually input by a user, may also receive a short message or other messages containing the authentication information sent by a network side device, and access the authentication operation with the acquired authentication information; and accessing the WLAN network to access the data service by using the AP after the authentication operation is completed.

In addition, based on the foregoing embodiments, a third embodiment of the present invention also provides a method for implementing wireless network access, where the method further includes, on the basis of the method flow of the foregoing embodiments:

step 170: before the network side equipment acquires the AP list allowed to be accessed and sends the AP list to the mobile terminal, the network side equipment judges whether the cellular network cell where the mobile terminal initiating the cellular network data service request is currently located has data service, if not, namely, a user in the cellular network cell never initiates the data service in the cell coverage area, the flow is ended; if the data service occurs, judging whether the AP in the AP list allowed to be accessed is divided into the data service flowing through the cell; and skipping the AP which is subjected to flow distribution, and if the data traffic which is not subjected to flow distribution exceeds a preset number of times or the data traffic which is not subjected to flow distribution exceeds a preset time, deleting the AP from the AP list which is allowed to be accessed, and sending the AP list which is newly allowed to be accessed after the AP is deleted to the mobile terminal.

It can be seen that, by adopting the method of the embodiment of the present invention, on the premise of not opening the WLAN network scanning function of the mobile terminal, when initiating the cellular network data service, according to the existence of the WLAN network in the coverage area of the current cellular network cell, and in combination with the offloading policy and the WLAN network access state, selecting to access the data service through the WLAN network or the cellular network, thereby implementing data service offloading supporting the hot spot area, further improving the WLAN network utilization ratio, and reducing the cellular network service and the signaling load.
