Problems solved by technology

However, it is not possible for the UE to know whether all available hotspots near its location are charging / free, and the ANDSF management object cannot indicate to the UE whether the WLAN access network is charging / free
[0017] 2. The ANDSF in the prior art, when selecting a WLAN access network for the UE, cannot indicate whether the UE can connect to the Internet using the WLAN access network
[0019] 3. The ANDSF in the prior art, when selecting a WLAN access network for the UE, cannot provide the link status of the WLAN access network currently connected to the Internet
[0020] If the WLAN access network provided by ANDSF to the UE can be connected to the Internet, the UE hopes to know the link status of the WLAN access network as a backhaul link, such as whether the link is connected or interrupted, and the uplink / downlink information such as road speed, so that the UE can choose whether to access the WLAN access network, but the existing ANDSF management object cannot provide the link status of the WLAN access network currently connected to the Internet
[0021] 4. The ANDSF in the prior art cannot let the UE know in advance the frequency band used by the WLAN access network when selecting a WLAN access network for the UE
However, under the existing mechanism, the UE cannot predict in advance the frequency band used by the AP near its location through ANDSF

Embodiment 1

[0114] This embodiment describes the method of considering whether the WLAN is charged when the UE obtains the inter-system mobility policy and access network discovery information from the ANDSF.

[0115] like image 3 As shown, the specific steps of the present embodiment method are described as follows:

[0116] In step 301, the location information of the ANDSF management object is extended, and a desired access network charging identity leaf is added.

[0117] The expected charging identifier of the access network may range from 0 to 1, where 0 indicates that a free WLAN access network is expected to be accessed, and 1 indicates that a charged WLAN access network is expected to be accessed.

[0118] In step 302, the ANDSF management object inter-system mobility policy is extended, and a charging identity leaf is added under the preferred access node.

[0119] The charging identifier can range from 0 to 1, where 0 indicates that access to the WLAN access network is free,...

Embodiment 2

[0132] This embodiment describes a method for considering a charging identifier when a UE supporting multiple access technologies obtains an inter-system routing policy from an ANDSF.

[0133] like Figure 4 As shown, the specific steps of the present embodiment method are described as follows:

[0134] In step 401, the routing policy between ANDSF managed object systems is extended, and a charging identification leaf is added under the routing rule node.

[0135] In step 402, the inter-system routing policy of the ANDSF performs prioritization of the access network, adding consideration of the charging ID.

[0136] According to the access technology, access identifier, charging identifier and access network priority, they are combined to obtain the order of the routing rules. For example, if a user wants to access a free WLAN access network, the priority of the access network in the policy is: when the access technology is WLAN, the access ID is SSID1, and the billing ID is...

Embodiment 3

[0146] This embodiment describes a method in which the ANDSF obtains the charging identifier of the access network from the AP through the advertisement server and transmits it to the UE to perform priority ranking of the access network.

[0147] like Figure 5 As shown, the specific steps of the present embodiment method are described as follows:

[0148] In step 501, the UE judges that a non-3GPP handover is initiated, and an ANDSF is found; or, the UE initiates a flow migration, multiple PDN connection or other multiple access connections, and an ANDSF is found.

[0149] In step 502, the UE sends a network access request message to the ANDSF, carrying the location information of the UE, the hotspot 2.0 capability and the desired charging identifier of the access network.

[0150] In step 503, the ANDSF judges that the hotspot 2.0 capability of the message in step 502 indicates that the UE supports hotspot 2.0 and carries the expected charging identifier of the access netwo...

Description

technical field [0001] The present invention relates to the technical field of mobile communication, in particular to a method, device and system for discovering and selecting a hotspot 2.0 access network. Background technique [0002] In order to maintain the competitiveness of the third-generation mobile communication system in the communication field, provide users with faster rate, lower delay, and more personalized mobile communication services, and at the same time reduce the operating costs of operators, the third-generation partner A 3rd Generation Partnership Project (abbreviated as 3GPP) standard working group is working on research on an evolved packet system (Evolved Packet System, abbreviated as EPS). The whole EPS system is divided into two parts, the wireless access network and the core network. The radio access network is divided into a 3GPP access network and a non-3GPP access network. [0003] The radio access network is composed of an evolved base statio...
