Abstract:
1. A method for assigning a location area to a mobile device in fallback from a first radio access network to a second radio access network, the location area being selected from a plurality of location areas, each corresponding to a separate location area code (LAC), the first radio access network comprising a base station node having a respective first counter corresponding to each LAC, the method comprising: receiving, by the base station node, a signal incorporating one of the LACs and further identifying data corresponding to the second radio access network; comparing the first counter corresponding to the one LAC with a predefined threshold value and if the first counter corresponding to the one LAC is less than the predefined threshold value, incrementing the first counter corresponding to the one LAC, otherwise incrementing a second counter corresponding to a unique combination of the one LAC and the further identifying data; and reporting, at a predetermined interval, the count from the second counter to the first radio access network.
