Abstract
A method, mobile station and base station for data transmission in a mobile radio system wherein interruption phases are inserted in a UMTS transmission in order to monitor GSM base stations. In order to reduce the number of these interruption phases, the mobile station is switched during these interruption phases to reception of characteristic data packets and of data packets which are to be detected and are transmitted by a GSM base station.
Claims67
A method for data transmission in a mobile radio system, the method comprising the steps of:
- transmitting first data between a first base station and a mobile station using a first transmission method;
- interrupting the transmission of the first data at specific times by interruption phases in which the mobile station interrupts at least one of the reception of the first data and the processing of received first data;
- switching, during interruption phases, the mobile station to reception of characteristic data packets which are transmitted by a second base station using a second transmission method;
- switching, during interruption phases, the mobile station to reception of the data packets to be detected and transmitted by the second base station using the second transmission method, wherein the reception of data packets to be detected and the characteristic data packets occurs parallel;
- and
- using knowledge about a frame structure of the data packets transmitted by the second base station in order to reduce a maximum effective total duration of the interruption phases.
