METHOD AND BASE STATION SYSTEM FOR CONFIGURATION OF A RADIO INTERFACE BETWEEN A MOBILE STATION AND A BASE STATION IN A TIME-DIVISION MULTIPLEX MOBILE RADIO SYSTEM FOR PACKET DATA TRANSMISSION

摘要

For signalling purposes in order to configure an air interface for packet data transmission (General Packet Radio Services - GPRS), the mobile stations are assigned time slots for signalling in the upwards direction by a base station according to a predetermined sequence and independently of packet data transmission. Since mobile stations to which, at a given moment, no physical channel is assigned are also assigned a signalling time slot in a fixed manner, the base station can carry out a continuous measurement with respect to the air interface. As a result, when packet data transmission is resumed, valid measured values for configuring the air interface are immediately available.
