Abstract
A system (10) and method (100) selects one of the gateways (40, 41) to set-up and maintain signalling resources associated with a call. Instead of having two gateways (40, 41) handle signalling resources, a single gateway (40) becomes the serving gateway for one or both of the subscriber units' call segment. The system and method do not establish a transit connection between gateways (40, 41).
Claims14
A method for setting-up and maintaining communication between a first subscriber unit located in a region serviced by a first gateway and a second subscriber unit located in a region serviced by a second gateway, comprising the steps of:
- a) establishing a first local connection between the first subscriber unit and the first gateway;
- and
- b) establishing a second local connection between the second subscriber unit and the first gateway without establishing a transit connection between the first gateway and the second gateway.
A method for setting-up and maintaining communication between a first subscriber unit and a second subscriber unit, comprising the steps of:
- a) a first gateway determining if the first subscriber unit is coupled to a public-switched telephone network;
- b) the first gateway establishing a local connection to the second subscriber unit if the first subscriber unit is coupled to the public-switched telephone network;
- c) the first gateway determining a location of the second subscriber unit if the first subscriber unit is not coupled to the public-switched telephone network;
- d) the first gateway determining if the second subscriber unit is coupled to a second gateway via the public-switched telephone network;
- and
- e) the first gateway establishing a first local connection to the first subscriber unit and a second local connection to the second subscriber unit if neither the first subscriber unit nor the second subscriber unit is coupled to the public-switched telephone network, wherein the first gateway establishes the first local connection and the second local connection without establishing a transit connection between the first gateway and a second gateway.
A method for setting-up and maintaining communication between a first subscriber unit and a second subscriber unit, comprising the steps of:
- a) a first gateway determining if the first subscriber unit is coupled to a public-switched telephone network;
- b) the first gateway establishing a local connection to the second subscriber unit if the first subscriber unit is coupled to the public-switched telephone network;
- c) the first gateway determining if the second subscriber unit is coupled to a second gateway via the public-switched telephone network if the first subscriber unit is not coupled to the public-switched telephone network;
- and
- d) the second gateway establishing a local connection to the first subscriber unit if the second subscriber unit is coupled to the public-switched telephone network, wherein the second gateway establishes the first local connection and the second local connection without establishing a transit connection between the first gateway and the second gateway.
A system comprising:
- a first subscriber unit located in a region serviced by a first gateway;
- a second subscriber unit located in a region serviced by a second gateway;
- and
- the first gateway coupled to the first subscriber unit by establishing a first local connection and coupled to a second subscriber unit by establishing a second local connection to the second subscriber unit, wherein the first local connection and the second local connection are established without establishing a transit connection between the first gateway and the second gateway.
A system comprising:
- a first subscriber unit located in a region serviced by a first gateway;
- a second subscriber unit located in a region serviced by a second gateway;
- and
- the first gateway coupled to the first subscriber unit via a public-switched telephone network and coupled to the second subscriber unit by establishing a local connection to the second subscriber unit without establishing a transit connection between the first gateway and the second gateway.
A system comprising:
- a first subscriber unit located in a region serviced by a first gateway;
- a second subscriber unit located in a region serviced by a second gateway;
- and
- the first gateway coupled to the first subscriber unit by establishing a local connection to the first subscriber unit and coupled to the second subscriber unit via a public-switched telephone network without establishing a transit connection between the first gateway and the second gateway.
A gateway comprising:
- a transceiver capable of communicating with a first subscriber unit located in region serviced by the gateway and a second subscriber unit located in a region serviced by a second gateway;
- and
- a processor, coupled to the transceiver, capable of establishing a first local connection to a first subscriber unit and establishing a second local connection to the second subscriber unit without establishing a transit connection between the first gateway and the second gateway.
