An A.S0001/IS-2001 based Access Network for packet data has a base station (BS), a packet control function (PCF), and a packet data serving node (PDSN). If a BS/PCF connection fails to be achieved, this is communicated from the PDSN to the PCF by a message that identifies a reason for the failure to register selected from a plurality of possible reasons. A similar message is sent from the PCF to the BS informing the BS of the reason for the failure to register. If the PDSN/PCF interface is released after being connected, this is communicated from the PDSN to the PCF by a message that identifies the reason for the release selected from a plurality of possible reasons. A similar message is sent from the PCF to the BS so that the BS is informed of the reason for the release. |
