Problems solved by technology

[0007] For the terminal UE, the MEC application service on the MEC host it accesses is represented by a domain name, and the data network needs to allocate a DNS server for it. The DNS server needs to convert the IP address of the MEC application domain name and return it to the UE, but In the prior art, the UE cannot obtain the IP address of the DNS server of the local network, so that the UE cannot resolve the domain name of the application service in the local network

Embodiment Construction

[0040] In order to make the purpose, technical solution and advantages of the present application clearer, the implementation manners of the present application will be further described in detail below in conjunction with the accompanying drawings.

[0041]The present invention provides various embodiments, and these embodiments are mainly used in the 3GPP core network, especially the MEC scene. In the solutions described in these embodiments, the 3GPP core network can dynamically assign a DNS server located in the local data network to the UE according to the location of the local data network visited by the UE. In the embodiment of the present invention, the local data network refers to a network independent of 3GPP, such as the Internet. Among them, the local data network includes MEC server, DSN server, MEC application service, etc. These examples are described in detail below.

Abstract

The invention provides a domain name system DNS server distribution method, device and system, and the method comprises that: a session management function SMF receives a session establishment requestmessage sent by terminal UE, and the request message comprises the name of a data network to be accessed by the UE; the SMF acquires a first DNS server IP address according to the data network name and the geographic position of the UE; and the SMF sends a session establishment response message to the UE, wherein the response message comprises the first DNS server IP address. The scheme is mainlyused in a 3GPP core network, and the 3GPP core network can dynamically allocate a DNS server located in a local data network to the UE according to the position of the local network accessed by the UE.

Description

technical field [0001] The invention relates to the communication field, in particular to a domain name server distribution method and device. Background technique [0002] Multi-access edge computing is to provide users with cloud-based computing capabilities at the edge of the operator's network close to mobile users. Users can use this capability to deploy applications at the edge of the network. Multi-access edge computing can also provide real-time network information (such as user location, base station load, etc.), using this information, users can develop differentiated applications. After deploying cloud computing capabilities to the edge of the network, a carrier-class service environment with high performance, low latency and high bandwidth can be created to accelerate the distribution and download of various content, services and applications in the network, allowing consumers to enjoy higher Quality web experience. [0003] Ultra-low-latency services are very ...
