Abstract

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.

Claims Analysis

Total Claims: 20
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.
Claim 2
Dependent Claim 109 words
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.
Claim 3
Dependent Claim 37 words
A method according to claim 1, further comprising paging the remote station from the mobile switching center, for routing an incoming call from the mobile switching center to the remote station while the data service is suspended.
Claim 4
Dependent Claim 111 words
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.
Claim 5
Dependent Claim 111 words
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.
Claim 6
Dependent Claim 57 words
A method according to claim 3 further comprising the steps of: establishing a stand-alone dedicated control channel between the remote station and the base station subsystem; sending a suspend message from the remote station to the base station subsystem including a data service protocol discriminator; and routing the suspend message to the serving data service support node.
Claim 7
Dependent Claim 27 words
A method according to claim 4, further comprising the steps of, following the step of routing: suspending data service while remaining logged on to the radio system.
Claim 8
Dependent Claim 28 words
