Abstract
When a mobile station MS1 determines during communication through a first network (1), that a second network (7) is available that offers better operational parameters for the communication, the mobile station sends a handover announcement (S 5.3) to the first network to offer it an opportunity to improve the operational parameters for the communication through the first network. The first network (1) may in response offer updated operational parameters (S5.6) with a view to encouraging the communication to continue through the first network. A decision (S5.7) whether to make a handover to the second network can then be made by comparing the updated operational parameters for the first network with the operational parameters for the second network.
