Abstract
A system and method of automatically transferring a call between telephones based on the distance between the two telephones is provided. First the proximity of a first telephone to a second telephone is determined. If the proximity is within a predetermined limit or threshold, calls directed to the first telephone are transferred to the second telephone. Security of the transfer may be ensured to prevent fraudulent use of the subscription of either telephone. Procedures are provided which permit any the above-mentioned steps to be performed either at the level of the individual telephones involved in the transfer, or by an element of the network, such as an MSC or HLR.
