Abstract:
1. A method in a radio network that includes a device, the method comprising: searching, via the device, for a primary access network; acquiring, via the device, the primary access network to form an association between the device and the primary access network; requesting, via the device, a service provided by a network connected to the primary access network; attaching, via the device, to the primary access network only when the service is requested by the device; determining whether a carrier-to-interference (C/I) ratio associated with the primary access network is greater than or equal to a first threshold; maintaining the association between the device and the primary access network when the C/I ratio is greater than or equal to the first threshold; determining whether the C/I ratio is greater than or equal to a second threshold when the C/I ratio is less than the first threshold; searching for an alternate access network when the C/I ratio is greater than or equal to the second threshold; and attaching the device to the primary access network when the C/I ratio is less than the second threshold.
