摘要
A service discovery method and apparatus based on a 6LoWPAN network are disclosed. The method includes: an initialization step, a host completing a router discovery process and a host address registration process respectively; a service registration step, a service agent SA advertising a service type that can be provided by the SA to a border route; and a service query step, a user agent UA querying information of the SA that can provide the service to the border route; the border route sending service query response information to the UA; and performing application interaction between the SA and the UA. In the embodiments of the present invention, with respect to limitations such as storage capacity and energy consumption of a 6LoWPAN terminal, an interaction mechanism is simplified as much as possible, and a service discovery message is simplified to reduce a data packet load, so as to make the 6LoWPAN terminal adaptable to an 802.15.4 low-rate wireless network, which implements low resource overhead and a simple mechanism; and a service discovery interaction method is particularly designed with respect to cases such as a huge number of application terminals and extensibility of application functions in the Internet of Things, which has advantages of high flexibility and strong extensibility.
