Abstract
Methods are described for use in a mobile device such that when the mobile device is connected to a generic access network (GAN) cell, the mobile device receives information including characteristics pertaining to one or more neighbor cells in a network that are not GAN cells. The mobile device can then determine at least a list of candidate neighbor cells for handover from the GAN cell to a cell that is not a GAN cell as a function of the information. In some embodiments of the invention the network that is not a GAN is a UTRAN network and a candidate list of 3G cells are generated.
Claims20
A method for use in a mobile device comprising:
- when the mobile device is connected to a generic access network (GAN) cell, receiving information comprising characteristics pertaining to one or more neighbour cells in a network that are not GAN cells;
- determining at least a list of candidate neighbour cells for handover from the GAN cell to a cell that is not a GAN cell as a function of the information, the determining comprising performing at least one of:
- reducing processing load of the mobile device directed to generating the list, and
- performing at least some of the processing load of the mobile device directed to generating the list prior to a trigger initiating handover.
A mobile device comprising:
- at least one wireless access radio configured to:
- receive information broadcast by at least a generic access network (GAN) and a network that is not a GAN comprising characteristics pertaining to one or more telecommunication cells in the network that is not a GAN cell;
- at least one processor configured to:
- determine a list of candidate cells for handover from a GAN cell to a cell that is not a GAN cell as a function of the information broadcast by at least one of the GAN and the network that is not a GAN, the at least one processor configured to perform at least one of:
- reduce processing load of the mobile device directed to generating the list, and
- perform at least some of the processing load of the mobile device directed to generating the list prior to a trigger initiating handover.
