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.

Abstract: A communication device has memory for storing a client application module, a server application module, and an operating system module which are executable by one or more processors. The client application module submits a request and, in response, the server application module causes the request to be processed with use of the operating system module. Prior to processing, an interface module causes one or more client process handles of a client stack of the client application module to be provided in a current process base of the operating system module. Thus, for the request, the operating system module checks one or more permission settings associated with the one or more client process handles as well as one or more permission settings associated with the one or more server process handles.
