Description

Non-3GPP access gateway selection method, network device and user equipment

The present invention relates to the field of communications technologies, and in particular, to a method for selecting a non-3GPP access gateway, a network device, and a user equipment. Background technique

With the development of communication technologies, 3GPP (The 3rd Generation Partnership Project) is trying to study an evolution network for future communication. Generally, the evolved network studied by the 3GPP may be referred to as a 3GPP evolved network; the 3GPP evolved network is mainly composed of an evolved radio access network (Evolved RAN) and an evolved packet core network (EPC).

Currently, the UE (User Equipment) can access the EPC of the 3GPP Evolved Network through the non-3GPP access technology. When the UE accesses the non-trusted non-3GPP network, the UE needs to access through the non-3GPP access gateway. As the network scale expands, the number of non-3GPP access gateway deployments begins to increase, requiring selection among multiple non-3GPP access gateways. Currently, the method of querying the Domain Name System (Domain Name System) server is generally used to select a non-3GPP access gateway. In the non-3GPP access gateway discovery process, the UE constructs the FQDN (Fully Qualified Domain Name) with the ID of the PLMN (Public Land Mobile Network) or the VPLMN (Visit Public Land Mobile Network). , full domain name) Query to the 匪S server, the DNS server returns the IP address of multiple non-3GPP access gateways corresponding to the APN (Access Point Name). When the UE selects among the multiple non-3GPP access gateways, it tends to select a local non-3GPP access gateway, or a non-3GPP access gateway that is located closer, or further consider the load between the non-3GPP access gateways. For the equalization problem, the UE should avoid selecting a non-3GPP access gateway that has been heavily loaded when selecting a non-3GPP access gateway.

VP Use the ID of the VPLMN to construct the FQDN to query the DNS server to select a non-3GPP access gateway. The query granularity is coarse, and the obtained query result is more, and the non-3GPP access gateway cannot be accurately selected. Summary of the invention
