Abstract:
1. A method comprising: establishing, at a first terminal, a call with a second terminal; calculating, at the first terminal, a first token value based on a first set of parameters related to the first terminal and a second token value based on a second set of parameters related to the second terminal; receiving, at the first terminal, a first network parameter and a second network parameter; combining, at the first terminal, the first network parameter with the first set of parameters to obtain a modified first set of parameters and the second network parameter with the second set of parameters to obtain a modified second set of parameters; determining, at the first terminal, a modified first token value based on the modified first set of parameters and a modified second token value based on the modified second set of parameters; determining, at the first terminal, that the modified first token value is greater than the modified second token value; determining, at the first terminal, that the call has dropped; and re-establishing, at the first terminal, the call.
