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.
Claims13
A method, comprising:
- establishing a call with a second terminal;
- publishing, at a first terminal, a first set of parameters comprising first terminal characterizations;
- receiving, at the first terminal, a second set of parameters comprising second terminal characterizations;
- calculating, at the first terminal, a first token value based at least in part on a weighted sum of the first set of parameters and a second token value based at least in part on a weighted sum of the second set of parameters;
- determining, at the first terminal, that first token value is greater than the second token value;
- determining, at the first terminal, that the call has dropped;
- and
- re-establishing, at the first terminal, the call.
A method comprising:
- publishing, at a first apparatus, a first set of parameters comprising first characterizations of the first apparatus;
- establishing a call with a second apparatus;
- receiving, at the first apparatus, a second set of parameters comprising second characterizations of the second apparatus;
- detecting, at the first apparatus, that a call has dropped;
- determining, at the first apparatus, a first token value based on a weighted sum of the first set of parameters and a second token value based on a weighted sum of the second set of parameters;
- determining, at the first apparatus, that the first token value is greater than the second token value;
- and
- re-establishing the call with the second apparatus.
A method comprising:
- supporting, at a network device, communications between a first apparatus and a second apparatus;
- publishing, at the network device, a first set of parameters comprising first characterizations of the first apparatus;
- receiving, at the network device, a second set of parameters comprising second characterizations of the second apparatus;
- detecting, at the network device, that the communications has terminated;
- determining, at the network device, that the terminated communications should be re-established based on at least one parameter from one of the sets;
- determining, at the network device, a first token value based at least in part on a weighted sum of the first set of parameters and a second token value based at least in part on a weighted sum of the second set of parameters;
- and
- facilitating the re-establishing of the communications between the first apparatus and the second apparatus.
