Method and apparatus for connecting to network in a short-range mobile communication terminal
First Claim
1. A method for reconnecting from a serving coordinator of a serving Wireless Personal Area Network (WPAN) to a coordinator of another WPAN, the method comprising:
- broadcasting a neighbor terminal information request message periodically to neighbor terminals;
receiving a neighbor information response message, having neighbor terminal information and Link Quality Information (LQI), from at least one neighbor terminal, responding to the neighbor terminal information request message;
storing a neighbor table having the LQI and the neighbor terminal information included in the neighbor information response message, the neighbor terminal information including the LQI, a Personal Area Network (PAN) Identifier (ID) of a WPAN to which the at least one neighbor terminal belongs and neighbor router information about the at least one neighbor terminal; and
reconnecting to the coordinator of the another WPAN based on the LQI and the neighbor terminal information and communicating with the coordinator of the other WPAN, wherein the neighbor table further includes information indicating whether the at least one neighbor terminal is a coordinator, a router or a terminal.

Abstract
A method and apparatus are provided for reconnecting from a serving coordinator of a serving WPAN to a coordinator of another WPAN. The method includes broadcasting a neighbor terminal information request message periodically to neighbor terminals; receiving a neighbor information response message, having neighbor terminal information and LQI, from at least one neighbor terminal, responding to the neighbor terminal information request message; storing a neighbor table having the LQI and the neighbor terminal information included in the neighbor information response message, the neighbor terminal information including the LQI, a PAN ID of a WPAN to which the at least one neighbor terminal belongs and neighbor router information about the at least one neighbor terminal; and reconnecting to the coordinator of the another WPAN using the LQI and the neighbor terminal information and communicating with the coordinator of the other WPAN.

8. An apparatus for reconnecting from a serving coordinator of a serving Wireless Personal Area Network (WPAN) to a coordinator of another WPAN by communications in a terminal, the apparatus comprising:
- a transceiver for transmitting and receiving signals and messages and receiving a neighbor information response message, having neighbor terminal information and Link Quality Information (LQI), from at least one neighbor terminal, responding to a neighbor terminal information request message; and
a controller for controlling the transceiver, broadcasting the neighbor terminal information request message periodically through the transceiver, storing a neighbor table having the LQI and the neighbor terminal information included in the neighbor information response message, the neighbor terminal information including the LQI, a Personal Area Network (PAN) Identifier (ID) of a WPAN to which the at least one neighbor terminal belongs and neighbor router information about the at least one neighbor terminal, and reconnecting to the coordinator of the another WPAN based on the LQI and the neighbor terminal information and communicating with the coordinator of the other WPAN, wherein the neighbor table further includes information indicating whether the at least one neighbor terminal is a coordinator, a router or a terminal. - View Dependent Claims (9, 10, 11, 12, 13, 14, 15, 16)
