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 system of base stations and mobile terminals distributed within a communications network, the system comprising:
- a number of survivability components located with at least one base station, the number of survivability components configured to:
- monitor communications within the communications network, and
- perform functions of corresponding components within the communications network,
- wherein one or more of the survivability components are further configured to monitor and cache network communications and traffic information before a network failure occurs, wherein the cached information is stored within a storage server of the at least one base station.
A base station of a communications network, the base station comprising:
- survivability components configured to maintain operation of the base station during a network failure of the communications network,
- wherein a number of the survivability components correspond to components within the communications network that perform a same function, and
- wherein one or more of the survivability components are configured to monitor and cache network communications and traffic information before the network failure occurs, wherein the cached information is stored within a storage server or the base station.
A method of operating a base station, the method comprising:
- determining an existence of a communications failure;
- responsive activating operations of survivability components in a number of base stations included in a communication network in response to determining the existence of the communications failure;
- and
- retrieving network communications and traffic information cached within a storage server of the base station in response to the existence of the communications failure,
- wherein the cached information is stored within the storage server prior to determining the existence of the communications failure.
