In-home digital network and method of assigning wireless terminals to base stations
First Claim
1. A method of assigning wireless terminals (E1, En) to base stations (B, B1, B2, Bm) in in-home digital networks, in which the connection strengths between the base stations and the terminals are measured and each terminal is assigned to just one base station as a function of the measured values thus obtained and, if present, of an already existing assignment between terminals and base stations, characterized in that all base stations calculate the assignment independently of one another on the basis of the same information and using the same algorithm.

Abstract
The invention relates to a method and a device for dynamic assignment of mobile terminals (E1, En) to one of a plurality of base stations (B1, B2, Bm) in an in-home digital network. The method is characterized in that it is executed autonomously in distributed manner at each base station (B1, B2, Bm). To this end, the base stations measure the connection strengths between them and the terminals located in their range (E1, En) and communicate the measured values thus obtained in a broadcast to all the other base stations. All the base stations may then calculate the assignment of terminals to base stations on the basis of the global information obtained using a predetermined algorithm, for example involving assignment of the terminal to the greatest connection strength taking account of hysteresis and a threshold value. If the newly calculated assignment has changed relative to the existing assignment, a base station sends a handover command to all the base stations, which command then triggers the corresponding take-over action. By performing the method in distributed manner, a high level of fault tolerance is achieved, wherein the method used is at the same time relatively simple to implement.
