Abstract
Self RF engineering is made possible for a wireless communication system by adding to the self-configuration capability the ability to set autonomously the power levels of the system base stations. The same data is employed as in self configuration. A further improvement for systems using the IS 136 Air Interface Standard consists of the capability to collect the required data through the functionalities of the MAHO/MACA (Mobile Assisted Hand Off/Mobile Assisted Channel Assignment). Improved system-initialization procedures are presented.
Claims17
In a wireless communications system having service areas partitioned into a plurality of cells, wherein a set of communications channels are available for allocation among said cells and efficient operation of the system relies on parameters established based on data collected during system operation, said system comprising:
- means for initiating system operation by specifying crude estimates of said parameters;
- means for acquiring said data during system operation;
- and
- means for improving estimates of said parameters using the acquired data.
In a wireless communications system having service areas partitioned into a plurality of cells wherein a set of communications channels are available for allocation among the cells and efficient operation of the system relies on parameters estimated based on data consisting of signal strength and interference measurements between base stations and mobiles, wherein said data is collected during system operation, said system comprising:
- means for initializing said parameters by specifying crude estimates of said parameters;
- means for acquiring said data by moving operator-controlled mobiles, registered or engaged in calls, about the system serving area;
- means for improving estimates of said parameters using the acquired data;
- and
