METHOD AND APPARATUS FOR COMMUNICATION DEVICE CONFIGURATION

摘要

A User Equipment UE (110) sends a PDP context activation request with an invalid APN to an SGSN (120). When detecting an invalid APN the SGSN creates a PDP context activation request towards a GGSN (130) and inserts a default APN. The GGSN detects the default APN and sends a RADIUS Accounting request message to a Device Management System DMS (140). The DMS initiates a device management configuration flow towards the UE using IP over the existing PDP context or an SMS bearer and responds with a RADIUS Accounting response message to the GGSN. When the RADIUS Accounting response message is received the GGSN will initiate a successful Create PDP context response towards the SGSN causing a successful PDP Context Activation Response towards the UE. An advantage of the invention is that it can detect devices having no GPRS configuration and devices having a faulty GPRS configuration.
