Abstract
A device searches for a primary access network, and acquires the primary access network. The device also requests a service provided by a network connected to the primary access network, and attaches to the primary access network only when the service is requested by the device.
Claims23
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.

A device, comprising:
- a memory to store a plurality of instructions;
- and
- a processor to execute instructions in the memory to:
- search for a primary access network,
- determine whether a carrier-to-interference (C/I) ratio associated with the primary access network is greater than or equal to a first threshold,
- determine 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,
- search for an alternate access network when the C/I ratio is greater than or equal to the second threshold,
- acquire the primary access network when the C/I ratio is greater than or equal to the first threshold,
- request a service provided by a network connected to the device via the primary access network after acquiring the primary access network, and
- attach to the primary access network based on requesting the service.
