Claims
- 1. A method of reducing radio channel access delay in a packet radio system,which system comprises a network element (100, 102, 132, 140) and at least one subscriber terminal (150), which, network element (100, 102, 132, 140) transmits channel allocation messages (A1, A2, . . . ) to the subscriber terminals (150), which channel allocation messages (A1, A2, . . . ) are transmitted by means of paging subchannels (G0 . . . G9 . . . ), and which subscriber terminals (150) listen to one or several paging subchannels (G0 . . . G9 . . . ), characterized by organizing the channel allocation messages (A1, A2, . . . ) to be transmitted to the subscriber terminals (150) such that the cumulative total delay of all the channel allocation messages (A1, A2, . . . ) is minimized by optimizing the use of the paging subchannels (G0 . . . G9 . . . ).
- 2. A method according to claim 1, characterized in that each subscriber terminal (150) only listens to desired paging subchannels (G0 . . . G9 . . . ).
- 3. A method according to claim 1, characterized in that the network element (100, 102, 132, 140) transmits channel allocation messages (A1, A2, . . . ) to the subscriber terminals (150) according to discontinuous reception (DRX).
- 4. A method according to claim 1, characterized in that the method is used for advantageously organizing and timing paging messages in a radio system (GPRS, General Packet Radio Service) employing packet transfer.
- 5. A packet radio system comprising a network element (100, 102, 132, 140) and at least one subscriber terminal (150),wherein the network element (100, 102, 132, 140) is arranged to transmit channel allocation messages (A1, A2, . . . ) to the subscriber terminals (150) by means of a number of paging subchannels (G0 . . . G9 . . . ) and which subscriber terminals (150) are arranged to listen to one or several paging subchannels (G0 . . . G9 . . . ), characterized in that the packet radio system is arranged to organize the channel allocation messages (A1, A2, . . . ) to be transmitted to the subscriber terminals (150) such that the cumulative total delay of all the channel allocation messages (A1, A2, . . . ) is minimized by optimizing the use of the paging subchannels (G0 . . . G9 . . . ).
- 6. A packet radio system according to claim 5, characterized in that each subscriber terminal (150) is arranged to listen to only desired paging subchannels (G0 . . . G9 . . . ).
- 7. A packet radio system according to claim 5, characterized in that the network element (100, 102, 132, 140) is arranged to transmit channel allocation messages (A1, A2, . . . ) to the subscriber terminals (150) according to discontinuous reception (DRX).
- 8. A packet radio system according to claim 5, characterized in that the packet radio system (GPRS, General Packet Radio Service) is arranged to advantageously organize and time paging messages.
