Abstract
The invention relates to a method at a cellular radio communications system which makes possible that the probability of congestion for multislot mobiles in said system is reduced. In the future, the GSM-system will offer high speed data services, at which one of these is HSCSD (High Speed Circuit Switched Data). The HSCSD-service includes two services called 'fixed service' and 'flexible service'. At the first mentioned service, the mobile is allocated a fixed number of time slots which shall be allocated during the whole call, whereas at the last mentioned service the number of allocated time slots can vary during the course of the call. The mobile stations of today with their simplex filters can perform only one thing at a time, i.e. either transmit, measure or receive signals. It therefore is important to have possibility to allocate consecutive time slots for multislot mobiles. By that demands are made for that the algorithm of the channel allocation in an efficient way shall be able to allocate the free time slots in order to increase the channel utilization and data speed. The invention solves this problem by utilizing intracell handover to meet the demands for consecutive time slots. This results in that the probability of congestion for mobiles which have requested 'fixed service' will be reduced and approach the probability of congestion for one-slot mobiles. Another advantage with intracell handover is that the data speed for mobiles which have requested 'flexible service' will increase.

Important Notes on Latency of Status data
Please note there is up to 60 days of latency in this Status indicator for certain status conditions. You can obtain up-to-date Status indicator readings by ordering PAIR for the file.
An application with the status "Published" (which means it is pending) may be recently abandoned, but not yet updated to reflect its abandoned status. However, an application filed less than one year ago is unlikely to be abandoned.
A patent with the status "Granted" may be recently expired, but not yet updated to reflect its expired status. However, it is highly unlikely a patent less than 3.5 years old would be expired.
An application with the status "Abandoned" is almost always current, but there is a small chance it was recently revived and the status not yet updated.
Important Note on Priority Date data
This priority date is an estimated earliest priority date and is purely an estimation. This date should not be taken as legal conclusion. No representations are made as to the accuracy of the date listed. Please consult a legal professional before relying on this date.
