Abstract

Communication devices may utilize services of multiple communication networks to obtain service for the various applications that the communication device provides. The communication device and/or one or more communication networks may determine which network is best suited to each application based on dynamic information regarding the service provided by each communication network. The application may be associated with a network at various times, such as upon the communication device encountering a network that supports a service needed by the application and/or upon initial invocation of the application. The communication device may be communicating with several communication networks simultaneously so that a single application may make use of multiple communication networks and/or so that multiple applications may each utilize different networks.

Claims
