Abstract:
A method and system that support re-establishing a dropped call or communication is disclosed. A terminal may publish its parameters to other terminals through in-band or out-of-band signaling. Token values may then be determined by a weighted sum of parameters, where the terminal having the largest weighted sum possesses the token. If the call or communication drops, the terminal possessing the token then initiates communication to the other terminals. In addition, a plurality of tokens may be used when there are more than two terminals in a call. The terminals may be partitioned into groups, where one of the terminals in each group possesses a token.
