  • Data-capable network prioritization with reject code handling
    Patent number: 7197312
    Abstract: Reject code handling is utilized for a more time-efficient selection of data-capable networks. One illustrative method for use in selecting a wireless communication network for communications involves the steps of causing a request for data connectivity to be transmitted through a first wireless network; reattempting the request for data connectivity through the first wireless network one or more times if a reject code comprising a non-critical error is received in response to the request for data connectivity through the first wireless network; and attempting to select a second wireless network for communications without reattempting the request for data connectivity through the first wireless network one or more times if a reject code comprising a critical error is received in response to the request for data connectivity through the first wireless network.
