| 1. A method for coordinating operation modes of a General Packet Radio Service (GPRS) network, comprising:
monitoring a status of a Gs link between a Serving GPRS Support Node (SGSN) and a Mobile Switching Center (MSC);
sending a Gs status message to a Base Station Controller (BSC) indicating the status of the Gs link;
selecting an operation mode from a plurality of operations modes based on the Gs status message, wherein each of the plurality
of operation modes specifies which one of a plurality of channels to use for circuit-switched pages and which to use for data
packet pages;
sending a first operation mode message from the BSC to a mobile subscriber (MS) instructing the MS to switch to the selected
operation mode; and
sending a second operation mode message from the BSC to the SGSN instructing the SGSN to switch to the selected operation
mode.
