Embodiment 1

[0131] When the UE decides to switch some specific IP flows to the WLAN access network according to the ANDSF policy and local policies (such as user preferences, access history, etc.), the UE obtains the information of the optional WLAN access network according to the ANDSF policy. Since the granularity of the ANDSF policy is different, the information obtained by the UE according to the ANDSF policy is different:

[0132] The ANDSF policy only restricts the target access technology to WLAN access, so the UE can know that the optional WLAN access network is any WLAN access network;

[0133] The ANDSF policy not only restricts the target access technology to WLAN access, but also provides the UE with the identification of one or more WLAN access networks and the priority information of these WLAN access networks, then the UE can obtain a WLAN access network priority A level list, the list includes identification information and priority information of the WLAN access network p...

Embodiment 2

[0147] This embodiment is used to explain the process of resolving the policy conflict when the HS policy of all available WLAN access networks of the UE conflicts with the ANDSF policy.

[0148] Scenario description:

[0149] The network coverage where the UE is located is as follows: Figure 4c shown, according to Figure 4c It can be known that the radio access technologies available to the UE include E-UTRAN, WLAN and WiMAX.

[0150] The UE supports the above three wireless access technologies, and can use the wireless interfaces corresponding to the above three wireless access technologies at the same time. Currently, all data traffic of the UE is routed from the E-UTRAN.

[0151] An ANDSF policy is valid in the UE. This ANDSF policy indicates that the UE needs to switch some traffic to the WLAN access network (the ANDSF policy only restricts the access technology, but does not restrict the specific WLAN access network identifier, which means that the UE can choose any ...

Embodiment 3

[0165] This embodiment is used to illustrate optional WLAN access networks and available WLAN access networks.

[0166] The optional WLAN access network identification and priority information obtained by the UE according to the ANDSF policy is: ,, (, the smaller the value of the priority, the higher the priority).

[0167] The location of the UE is only covered by WLAN_1, WLAN_2 and WLAN_4, but not covered by WLAN_3. The schematic diagram of WLAN network coverage is as follows Figure 4e As shown, the UE can search for the signals of WLAN_1, WLAN_2 and WLAN_4. Since WLAN_1 and WLAN_2 are optional WLAN access network identifiers provided by the ANDSF policy, the available WLAN access networks of the UE are WLAN_1 and WLAN_2. The UE only Obtain the HS policies of WLAN_1 and WLAN_2.

Abstract

An embodiment of the invention discloses an Internet access and strategy sending method and device and relates to the wireless communication field. The Internet access and strategy sending method and device are used for solving the problem of network access of a terminal when an ANDSF (Access Network Discovery and Selection Function) strategy is in conflict with HS strategies. According to the scheme, a new ANDSF strategy which is not in conflict with the HS strategies is obtained from an ANDSF server through the terminal when the available HS strategies which are accessed into an WLAN (Wireless Local Area Network) are in conflict with the ANDSF strategy and accordingly an access network can be selected and accessed by the terminal according to the new ANDSF strategy and accordingly the problem of the network access of the terminal when the ANDSF strategy is in conflict with the HS strategies is solved.

Description

technical field [0001] The present invention relates to the field of wireless communication, in particular to a network access and strategy sending method and device. Background technique [0002] The Third Generation Partnership Project (The Third Generation Partnership Project, 3GPP) defines the access network discovery and selection function (Access Network Discovery and Selection Function, ANDSF) function that supports the UE to perform access network discovery and selection, wireless fidelity (wireless The fidelity, Wi-Fi) Alliance (Wi-Fi Alliance, WFA) defines a hotspot (Hotspot) 2.0 specification that supports a user terminal (User Equipment, UE) to select an access network. The UE can receive the policies related to the wireless local area network (Wireless Local Area Network, WLAN) access network from the ANDSF server and the advertisement server at the same time. At this time, there may be conflicts between the policies received by the UE from different servers. T...
