  • Wireless Device and Method for Determining Which APN to Use
    Publication number: 20080293407
    Abstract: Wireless devices and methods are provided for performing mobile discovery of an active data subscription. This involves a wireless device attempting to register using an APN that is one of a CDMA-centric APN and a GSM-centric APN. If that attempt fails, then the wireless device attempts to register using an APN that is the other of the CDMA-centric APN and the GSM-centric APN. In some cases the first APN attempted is always the CDMA-centric APN; in some cases the first APN attempted is a previously successfully used APN. For wireless devices with a data roaming enable/disable mechanism, the method can be executed while data roaming is disabled such that when data roaming is enabled, the proper APN to use will have been previously identified.
