Abstract

The embodiment of the invention provides a method and device for obtaining a local service and generating a link local address. The method is applied to user equipment, and comprises the following steps: after the user equipment accesses an IPv6 network, whether a router notification message is received is determined, wherein the router notification message carries a uniform resource identifier URI for indicating a local service entry; if the router notification message is not received, a link local address corresponding to a target local service is obtained, and service description information corresponding to the target local service is embedded in the link local address; and obtaining the target local service based on the link local address. Thus, the local service is obtained through the link local address, and the required target local service can be obtained only by accessing the IPv6 network without depending on a DNS server, a DHCP server and other servers.

Description

technical field [0001] The present application relates to the technical field of the Internet, and in particular to a method and device for obtaining local services and generating link-local addresses. Background technique [0002] In recent years, more and more people frequently travel around due to the needs of life and work. However, local services such as local time service, local emergency communication service, local network authentication service, local geographic information service, etc. often change with the geographical location of the user vary with location. [0003] At present, local services are obtained mainly through DHCP (Dynamic Host Configuration Protocol) or DNS (Domain Name System, domain name system). However, since these implementations depend on other services such as DNS servers and DHCP servers, The system structure is relatively complex, which is not conducive to deployment, which makes the support of user equipment poor. It often happens that th...
