Fig. 1 sets up the flow chart of the embodiment of the method one of WLAN connections between user equipment and Wi-Fi access points for the present invention, and the present embodiment is illustrated so that base station is executive agent as an example, such as Fig. 1 institutes Show, the method for the present embodiment can include：

S 101, base station receive the Wi-Fi metrical informations that UE is sent.

Before S101, UE in Idle state is resided in some mobile cellular network cell, when user needs initiation business to be transferred to connected state, UE can set up wireless heterogeneous networks by initiating random access procedure on a random access channel with mobile cellular network（Radio Resource Control, hereinafter referred to as：RRC) connection and Deta bearer using mobile cellular network so that enter row data communication, when base station is thought to need UE being diverted in WLAN, shunting order can be sent by RRC signaling message to UE to indicate and Wi-Fi measurement configuration informations, contained in Wi-Fi measurement configuration informations and indicate when UE measures, how to measure and information that when measurement result reports, UE receive after according to Wi-Fi measurement configuration informations carry out Wi-Fi signal measurement obtain Wi-Fi metrical informations, most after to base station transmission Wi-Fi metrical informations.

S 102, base station are according to Wi-Fi metrical informations and the load information of each Wi-Fi access points corresponding with Wi-Fi metrical informations, select to provide the target Wi-Fi access points of Radio Service for UE, and preserve UE and target Wi-Fi access points mapping relations.

Wherein, each Wi-Fi access points can report its load information to base station, base station has chosen whether that suitable Wi-Fi access points are used for UE according to the load information of Wi-Fi metrical informations and each Wi-Fi access points corresponding with Wi-Fi metrical informations, and the target Wi-Fi access points of selection and UE mapping relations are preserved if having suitably.

S103, base station send Wi-Fi authentication claim frames to target Wi-Fi access points, after the response message of target Wi-Fi access points return is received, response message is transmitted to UE according to mapping relations, to indicate the MAC Address for the target Wi-Fi access points that UE is returned according to base station, set up WLAN with target Wi-Fi access points and be connected.

Wherein, specifically, in S102 it is base station selected to the suitable target Wi-Fi access points used for UE when, Wi-Fi authentication claim frames are sent to target Wi-Fi access points, Wi-Fi access points can respond after receiving Wi-Fi authentication claim frames, if authentication response message is returned to if to base station, response message is transmitted to UE by the mapping relations that base station can be preserved before, to indicate the MAC Address for the target Wi-Fi access points that UE is returned according to base station, set up WLAN with target Wi-Fi access points and be connected.

The method for setting up WLAN connections between user equipment and Wi-Fi access points that the present embodiment is provided, by base station according to UE Wi-Fi metrical informations sent and corresponding with Wi-Fi metrical informations The load information selections of each Wi-Fi access points the target Wi-Fi access points of Radio Service are provided for UE, then to target Wi-Fi access points transmission Wi-Fi authentication claim frames, receive

After the response message of Wi-Fi access points, response message is transmitted to according to the mapping relations preserved before

UE, indicate UE can just blunt target Wi-Fi access points returned according to base station MAC Address, WLAN is set up with target Wi-Fi access points to be connected, it is achieved thereby that base station can replace the authentication process of UE progress Wi-Fi access points, avoid access delay, base station also can control UE and select suitable Wi-Fi access points access simultaneously, improve service quality.

Fig. 2 sets up the flow chart of the embodiment of the method two of WLAN connections between user equipment and Wi-Fi access points for the present invention, on the basis of Fig. 1 illustrated embodiments, further, Wi-Fi metrical informations in S101 include the information of the best Wi-Fi access points of signal quality, or the signal quality best corresponding call number of Wi-Fi access points, the wherein information of Wi-Fi access points includes Wi-Fi

MAC Address, as shown in Fig. 2 the S103 of embodiment one is specifically included：

S103a, base station are according to UE Wi-Fi ability informations, generate Wi-Fi authentication claim frames, it is then sent to target Wi-Fi access points, wherein, UE Wi-Fi ability informations, which are base stations, is obtained and stored in base station being set up with UE during RRC is connected, UE Wi-Fi ability informations refer to the information such as the MAC Address of the Wi-Fi classifications that UE supports, the working frequency range supported and UE.

The MAC Address of target Wi-Fi access points is returned to UE by S103b, base station by response message, i.e. base station is received after the response message of target Wi-Fi access points return, the MAC Address of target Wi-Fi access points is sent to UE, is connected so that UE sets up WLAN according to the MAC Address of target Wi-Fi access points with target Wi-Fi access points.

Base station generates Wi-Fi authentication claim frames according to UE Wi-Fi ability informations in the present embodiment, it is then sent to target Wi-Fi access points, realize the authentication process that base station can replace UE to carry out Wi-Fi access points, avoid access delay, base station also can control UE and select suitable Wi-Fi access points access simultaneously, improve service quality.

Fig. 3 sets up the flow chart of the embodiment of the method three of WLAN connections between user equipment and Wi-Fi access points for the present invention, on the basis of embodiment illustrated in fig. 1, further, Wi-Fi metrical informations include the information of the best Wi-Fi access points of signal quality, or the best corresponding call number of Wi-Fi access points of signal quality, or the corresponding call number of access point group where the best Wi-Fi access points of signal quality, wherein the information of Wi-Fi access points includes Wi-Fi MAC Address, such as Fig. 3 institutes Show, the S103 of embodiment one is specifically included：

S103c, base station are according to UE Wi-Fi ability informations, generate Wi-Fi authentication claim frames, it is then sent to Wi-Fi access points all in the access point group where target Wi-Fi access points, UE Wi-Fi ability informations, which are base stations, is obtained and stored in base station being set up with UE during RRC is connected.Wi-Fi authentication claim frames are sent in base station before Wi-Fi access points all in the access point group where target Wi-Fi access points, base station can by the Wi-Fi access points in its coverage according to locus carry out packetizing management, and cell system message broadcast in broadcast packe information.

S103d, base station also preserve the mapping relations of Wi-Fi access points all in access point group where UE and target Wi-Fi access points.

S103e, base station are returned to the MAC Address of target Wi-Fi access points by response message

UE。

Specifically, when UE is by the certifications of Wi-Fi access points all in the access point group where target Wi-Fi access points, base station can receive the response message that each Wi-Fi access point is replied in group, base station is received after the response message of target Wi-Fi access points return, the MAC Address of target Wi-Fi access points is directly sent to UE, is connected so that UE sets up WLAN according to the MAC Address of target Wi-Fi access points with target Wi-Fi access points.

If follow-up UE is moved in the access point group where target Wi-Fi access points under another Wi-Fi access points covering, then UE obtains the MAC Address of another Wi-Fi access points by obtaining the beacon frame of another Wi-Fi access points, sets up WLAN with another Wi-Fi access points and is connected.
