Radio system with suspension of packet data service during non-data service connection
First Claim
1. In a radio system with data capability comprising a remote station, a base station subsystem, a mobile switching center and a serving data service support node, a method of operation comprising the steps of:
- logging on to the radio system by the remote station;
establishing packet data service between the remote station and the serving data service support node;
suspending packet data service while remaining logged on to the radio system by sending a suspend service message from the mobile switching center to the serving data service support node; and
signalling from the serving data service support node to the mobile switching center that packet data service is suspended.

Abstract
A method of operation of a radio system with data capability, for example a GSM cellular radio system with GPRS capability includes suspending data service while remaining logged on to the system and signalling from a remote station (10) to a serving data service support node (13) via a base station subsystem (11) that data service is suspended. In another aspect, data is exchanged over a data channel (100) during first time periods (102) and exchange of data over the data channel stops during second time periods (103) intermittent between the first time periods. During the second time periods paging requests communicated on a paging channel (101) are monitored at the remote station (10). A non-data service paging request is identified on the paging channel and the system responds to the non-data service paging request.

3. In a radio system with data capability comprising a remote station, a base station subsystem and a serving data service support node, a method of operation comprising the steps of:
-
logging on to the radio system; establishing data service; exchanging data over a data channel on a first frequency during first time periods and stopping exchange of data over the data channel during second time periods intermittent between the first time periods; during the second time periods, monitoring, at the remote station, paging requests communicated on a paging channel on a second frequency; identifying a non-data service paging request on the paging channel; and responding to the non-data service paging request. - View Dependent Claims (4, 5, 6)

15. In a radio system with data capability comprising a remote station and a base station subsystem, a method of operation comprising, at the remote station, the steps of:
-
exchanging two-way packet data on a data channel on a first frequency during first time periods associated with a data group; and monitoring a paging channel on a second frequency during second time periods intermittent between the first time periods, the second time periods being associated with a voice group, for receipt of notification of an incoming circuit switched voice call.
