Abstract
A method of establishing communication links during a failure within a mobile communications network includes detecting disruptions in communications between a plurality of base stations and a plurality of mobile terminals. Survivability components are activated within the base station and the mobile terminal to operate in a survivability mode. The survivability mode enables communications and services to be provided by the surviving base stations to mobile terminals through activated survivability components. The alternate communication links may operate for as long as a disruption exists.
Claims18
A mobile terminal comprising:
- one or more survivability components configured to:
- monitor communications within a communications network;
- cache network communications and traffic information before a network failure occurs, wherein the one or more survivability components store the cached network communications and traffic information in at least one storage device within the mobile terminal;
- and
- upon a network failure, perform a same function as one or more components within the communications network using the cached network communications and traffic information,
- wherein the one or more survivability components are configured to activate a survivability mode upon detecting a disruption of communication within the communications network, wherein activating the survivability mode causes the mobile terminal to consume less power and radio resources than consumed when the survivability mode is inactive.
A base station of a communications network, the base station comprising:
- one or more survivability components configured to:
- monitor communications within the communications network;
- cache network communications and traffic information within a storage server located on the base station before a network failure occurs;
- upon a network failure, perform a same function as one or more components within the communications network using the cached network communications and traffic information;
- and
- activate a survivability mode upon detecting a disruption of communication within the communications network, wherein activating the survivability mode causes the base station to consume less power and radio resources than consumed when the survivability mode is inactive.
A method of operating a base station, the method comprising:
- monitoring communications within a communications network;
- caching network communications and traffic information within a storage server located on the base station before a network failure occurs;
- upon a network failure, performing, by the base station, a same function as one or more components within the communications network using the cached network communications and traffic information;
- and
- activating a survivability mode upon detecting a disruption of communication within the communications network, wherein activating the survivability mode causes the base station to consume less power and radio resources than consumed when the survivability mode is inactive.
