Method and system for providing availability and reliability for a telecommunication network entity
First Claim
1. A system for providing redundancy for an entity in a telecommunications network, the system comprising:
- a first network entity of a first network, adapted to send and receive traffic; and
a second network entity, of a second network, configured to operate as a standby network entity, wherein the second network entity takes control of only a portion of the functions of the first network entity in response to a partial failure in the first network entity when a failure to receive either a primary status message by the second network over the first network or a secondary status message from the first network over the second network.

Abstract
Geographical redundancy and an efficient switchover process to redundant equipment (210) is achieved by separating active main equipment (220) and standby redundant equipment in different geographical locations so that failures can be avoided in the event of a natural disaster or other event that affects an entire building or region. In addition, partial switchover can be performed for components or functions that become inoperative to corresponding redundant components in the standby equipment. To provide further redundancy and prevent unneeded switchovers, status or heartbeat messages are transmitted between the active main equipment and standby redundant equipment over two different networks.

7. A method for providing redundancy for an entity in a telecommunications network, the method comprising:
- detecting that a first call server has become partially or completely disabled;
determining that no primary status message has been received by the first call server over a first network;
determining that no secondary status message has been received by the second call server over a second network; and
redirecting at least a portion of traffic from the first call server to the second call server in a geographically remote location. - View Dependent Claims (8, 9, 10, 11, 12, 13, 14)

15. A method for providing redundancy for an entity in a telecommunications network, the method comprising:
- transmitting a primary status message over a first network from a standby network entity to an active network entity;
determining that no primary status message has been received from the active network entity by the standby network entity over the first network;
transmitting a secondary status message over a second network from the standby network entity to the active network entity;
determining that no secondary status message has been received from the first active network entity by the standby network entity over the second network; and
initiating a switchover of traffic control from the active network entity to the standby network entity. - View Dependent Claims (16, 17, 18, 19, 20, 21)
- transmitting a primary status message over a first network from a standby network entity to an active network entity;
