Title:
METHOD OF SUBSCRIBING TO NETWORK IN WIRELESS NETWORK
Document Type and Number:
WIPO Patent Application WO/2014/112721
Kind Code:
A1
Abstract:
The present invention relates to a method of a terminal subscribing to a network via a router or an end device in a wireless network (WN) of a tree structure comprising routers and end devices. According to the present invention, each router receives, from the parent router thereof, addresses which can be used independently for child routers or child end devices thereof, and divides the addresses into general addresses and special addresses. The present invention allows a terminal wishing to subscribe to a network to subscribe to the network by using a special address of the end device, only when the terminal cannot subscribe to the network by using a general address of the end device, thereby minimizing address depletion to be used for subscription of terminals and facilitating the end devices to subscribe a network. Additionally, if a router determines that end devices of peripheral devices have finished subscription to a network, the router selects as many child end devices having a low received signal strength (RSS) (i.e., easy to extend a network remotely) as the number of general addresses available for child routers and then converts the child end devices to child routers, thereby providing network extensibility by an increase in network depth and minimizing the use of the special addresses by the router. Furthermore, if a terminal wishing to subscribe to a network via an end device fails to subscribe to the network, or a terminal which has subscribed to a network via a router wishes to re-subscribe to the network, the present invention facilitates such a terminal to re-subscribe to the network by allowing the terminal to subscribe to the network using a special address for the router. Compared to conventional techniques, the present invention can significantly enhance the success rate of subscription to a large-scale WN through the two-step address allocation and the selection of the child routers.
