Embodiment 1

[0074] Figure 3A It is a schematic diagram of a WLAN access method provided by an embodiment of the present invention. refer to Figure 3A , this embodiment provides a WLAN access method, the method may include:

[0075] 1. The UE accesses the 3GPP network. The 3GPP network can be, for example, GERAN (GSM / EDGE RadioAccess Network, GSM / EDGE Radio Access Network) network, UTRAN (UMTS Terres trial Radio AccessNetwork, UMTS Terrestrial Radio Access Network) network or E-UTRAN (Evolved UMTS Terrestrial RadioAccess Network, evolved UMTS Terrestrial Radio Access Network) network.

[0076] After the UE accesses the 3GPP network, the 3GPP access network element or the 3GPP core network element can obtain the access location information of the UE and notify the access selection control network element.

[0077] 2. The 3GPP access network element or the 3GPP core network element notifies the access selection control network element (for example, network elements such as ANDSF, PCRF, ...

Embodiment 2

[0106] Figure 3B It is a schematic diagram of a WLAN access method provided by an embodiment of the present invention. refer to Figure 3B , this embodiment provides another WLAN access method, which is substantially the same as the method described in Embodiment 1, and only the differences will be described in detail below. The WLAN access method provided in this embodiment may include:

[0107] 1-4: Same as steps 1-4 in Example 1.

[0108] 5. After learning the access location information of the UE, the access selection control network element acquires the WLAN AP access information of the UE at the access location corresponding to the access location information from the ANDSF. Specifically, the access selection control network element sends an AP access information query request to ANDSF, and the access information query request carries the access location information of the UE, and the ANDSF returns the UE access location information according to the UE access locatio...

[0124] Figure 3C It is a schematic diagram of a WLAN access method provided by an embodiment of the present invention. refer to Figure 3C , this embodiment provides another WLAN access method, which is substantially the same as the method described in Embodiment 1, and only the differences will be described in detail below. refer to Figure 3C , the WLAN access method provided in this embodiment may include:

[0125] 1-4: Same as steps 1-4 in Example 1.

[0126] 5. After obtaining the access location information of the UE, the access selection control network element notifies the ANDSF of the UE's access location information. In this step, the access selection control network element may also notify the ANDSF of the requested service type.

[0127] 6. If there is a WLAN AP at the UE access location, ANDSF obtains the WLAN AP access information at the UE access location, selects the AP, and sends a WLAN access request to the UE, and the WLAN access request carries the ne...

Abstract

The invention provides a wireless local area network (WLAN) access method which can save electric energy of user equipment (UE). The method comprises the following steps: obtaining an access positionof UE; acquiring AP access information of the UE at the access position; selecting an AP to perform WLAN access according to the obtained AP access information; and sending the AP access information of the selected AP to the UE. The invention also provides another WLAN access method and a corresponding device.

Description

technical field [0001] The present invention relates to the communication field, in particular to a WLAN (Wireless Local Area Network, wireless local area network) access method and device. Background technique [0002] When the UE (User Equipment, user equipment) needs to access the WLAN, it continuously scans the nearby WLAN networks to obtain a list of nearby WLAN APs (AccessPoints, access points), and then selects one of the WLAN APs to access the WLAN network to realize WLAN network access. [0003] In the above process, the UE needs to open the WLAN network interface all the time, and needs to continuously scan the WLAN network. In this way, the power consumption of the UE will be relatively large. Contents of the invention [0004] Embodiments of the present invention provide a WLAN access method and device, which can save power of UE. [0005] In order to achieve the above object, embodiments of the present invention adopt the following technical solutions: [0...
