Method and an apparatus for attachment of a remote station to a base station in a multicellular communications network
First Claim
1. A method for network attachment of a remote station to a base station in a multicellular communications network having base stations and a plurality of remote stations, wherein said base and remote stations emitting frames of information using a sequence of changing frequency hops of different operating frequencies, said method comprising at the remote station the steps of:
- a) determining a set of "n" operating frequencies (Fi),b) listening sequentially on each of said operating frequencies (Fi) for frames of information emitted by base or remote stations, said listening being for a fixed period of time equal to 1/n of the frequency hopping period (FH) of a base station,c) collecting and processing the information contained in a frame when a frame of information is received during one of the fixed period, andd) selecting a base station for attachment.

Abstract
In a multicellular communications network system comprising base stations and a plurality of remote stations, a remote station listens for frames of information emitted by the different base or remote stations, in order to insert the network. The base stations and the remote stations comprise means for emitting the frames of information using a sequence of changing frequency hops of different operating frequencies. The remote station determines a set of "n" operating frequencies (Fi), from which it sequentially listens for a fixed period of time equal to 1/n of the frequency hopping period (FH) of a base station. When a frame of information is received by the remote station during one of the fixed period, the information is collected and processed in order to select the base station for attachment.
