Abstract:

This disclosure relates to techniques for a wireless device to re-establish a packet data network connection. The wireless device may establish a packet data network connection via a cellular link with a cellular base station. Information identifying a bearer associated with the packet data network connection may be stored by the wireless device. The wireless device may determine whether the bearer associated with the packet data network connection is active. The packet data network connection may be released by the wireless device and the wireless device may attempt to re-establish the packet data network connection if the bearer associated with the packet data network connection is determined to not be active.
