Wireless network architecture for GPRS over 30kHz channels
First Claim
1. A method of implementing packet data service at a mobile terminal in a radio-communications network, comprising:
- sending or receiving data packets via a first packet data service over a first radio-communications channel comprising a first bandwidth; and
sending or receiving data packets via a second packet data service over a second radio-communications channel comprising a second bandwidth, the second radio-communications channel being a circuit-switched control channel.

Abstract
A radio-communications system includes a mobile terminal, a first base station, and a second base station. The mobile terminal transmits first packets over a first radio-communications channel that has a first bandwidth, and transmits second packets over a second radio-communications channel that has a second bandwidth. The second radio-communications channel includes a circuit-switched control channel. The first base station receives and forwards the first packets, via a first path, to a packet-switched network. The second base station receives and forwards the second packets, via a second path, to the packet-switched network.

13. A method of implementing packet data service at a mobile terminal in a radio-communications network, comprising:
-
determining a preference between a first packet data service and a second packet data service;
determining, if the first packet data service is preferred, whether the first packet data service is available;
attaching to the first packet data service if the first packet data service is available; and
attaching to the second packet data service if the first packet data service is unavailable.
