Apparatus, method and system for providing a default mode for authentication failures in mobile telecommunication networks

An apparatus for providing a default mode for authentication failures in a mobile telecommunication network, the network having been accessed by a mobile unit through a call leg, the apparatus comprising:

• a network interface for transmitting and receiving a plurality of call legs;
• a memory;
• and
• a processor coupled to the network interface and to the memory, wherein the processor, when operative, is configured to perform an authentication procedure;
• the processor further configured, when the authentication procedure has resulted in an authentication failure, to denying the mobile unit access to the network, to terminate a communication session with the mobile unit;
• and to provide for an announcement on the call leg to the mobile unit.

A system for providing a default mode for authentication failures in a mobile telecommunication network, the network having been accessed by a mobile unit through a call leg, the system comprising:

• an authentication center;
• and
• an originating mobile switching center couplable to the authentication center, wherein the originating mobile switching center, when operative, is configured to perform an authentication procedure;
• the originating mobile switching center further configured, when the authentication procedure has resulted in an authentication failure, to receive a message from the authentication center to deny the mobile unit access to the network, to terminate a communication session with the mobile unit, and to provide for an announcement on the call leg to the mobile unit.

A system for providing a default mode for authentication failures in a mobile telecommunication network, the network having been accessed by a mobile unit through a call leg, the system comprising:

• an adjunct network entity, the adjunct network entity having an announcement application node;
• a home location register having an authentication center;
• and
• an originating mobile switching center couplable to the authentication center, wherein the originating mobile switching center, when operative, is configured to perform an authentication procedure by calculating a first shared secret data result and comparing the first shared secret data result with a second shared secret data result received from the mobile unit;
• the originating mobile switching center further configured to determine an authentication failure when the first shared secret data result is not identical to the second shared secret data result;
• the originating mobile switching center further configured, when the authentication procedure has resulted in the authentication failure, to transmit an authentication status report message to the authentication center indicating the authentication failure, and to receive an authentication status report return result message from the authentication center, the authentication status report return result message including a deny access parameter and an announcement list parameter;
• the originating mobile switching center further configured to deny the mobile unit access to the network and to terminate a communication session with the mobile unit by tearing down a second call leg to a third party;
• and wherein the originating mobile switching center is further configured to route the call leg to the announcement application node to provide for an announcement on the call leg to the mobile unit, and subsequent to the provision of the announcement, to route the call leg to a customer service center.

A system for providing a default mode for authentication failures in a mobile communication network, the network having been accessed by a mobile unit through a call leg, the system comprising:

• means for performing an authentication procedure;
• means, when the authentication procedure has resulted in an authentication failure, for denying the mobile unit access to the network and terminating a communication session with the mobile unit by tearing down a second call leg from a network switch to a third party;
• means for providing an announcement on the call leg to the mobile unit;
• and
• means for routing the call leg to a customer service center.
