Optimized adjacent channel search and timeslot assignment for multiple timeslot mobile stations
First Claim
1. In a method for transmission of data packets between at least one base station and at least one mobile station in a mobile radio system, an improvement which comprises:
- transmitting each of the data packets in time frames having a fixed number of timeslots;
transmitting the data packets from the mobile station in a plurality of successive timeslots;
transmitting at least one of control data packets and no data packets from a given base station to the mobile station during predetermined time frames while the mobile station is connected to the given base station;
respectively making available to the mobile station a time interval longer than a predetermined time frame for at least one of receiving synchronization data packets and measuring signal levels of adjacent base stations; and
transmitting the data packet from the given base station at least one of immediately before and immediately after a predetermined time frame is at least partially not received by the mobile station.

Abstract
A method and a system for transmission of data packets between base stations and mobile stations in a mobile radio system includes transmitting each of the data packets in time frames having a fixed number of timeslots, and a mobile station transmitting data packets in a plurality of successive timeslots. In the method and system, while the mobile station is connected to a present base station, a transmitting unit of the present base station transmitting control data packets or no data packets to the mobile station during predetermined time frames while the mobile station is connected to the given base station, and respectively making available to a receiving unit of the mobile station a time interval longer than a predetermined time frame for receiving synchronization data packets and/or measuring signal levels of adjacent base stations.

9. A system for transmission of data packets in a mobile radio system, comprising:
-
at least one base station having a transmitting unit; and at least one mobile station having a receiving unit, said at least one base station and said at least one mobile station transmitting data packets in time frames having a fixed number of timeslots, said at least one mobile station transmitting data packets in a plurality of successive timeslots, in which, while said at least one mobile station is connected to a given one of said at least one base station, said transmitting unit of said given one of said at least one base station transmits at least one of control data packets and no data packets to said at least one mobile station during a predetermined time frame, a respective one of said receiving units of said at least one mobile station having an available time interval longer than the predetermined time frame for at least one of receiving synchronization data packets and measuring signal levels of adjacent base stations, said receiving unit of said at least one mobile station at least partially not receiving a data packet transmitted by said transmitting unit of said given base station at least one of immediately before and immediately after the predetermined time frame. - View Dependent Claims (10, 11, 12, 13, 14, 15, 16)
