摘要
The disclosure is directed to techniques for supporting failover between different network protocol addressing families in a wireless communication network. The techniques may be implemented in a mobile wireless communication device. A logical interface selects a physical interface for access to the network in response to a request from an application module. The network access request issued by the application module need not specify a network protocol type. Instead, upon selection of the physical interface, the logical interface notifies the application of the networkprotocol type associated with the physical interface. The logical interface may select a physical interface corresponding to a particular network protocol when available, based on connection preferences specified by the application module or a global setting within the device. If a physical interface corresponding to the network protocol is not available, however, the logical interface selects a physical interface corre sponding to a different network protocol.
