  • Technique for managing sessions with entities in a communication network
    Patent number: 9258367
    Abstract: A technique for managing sessions in a communication network that does not subscribe to registration events immediately after an entity in the network is registered but rather delays subscribing to these events until a time that such notification would be normally used, such as after a revocable session has been established with the entity. An entity registers to enable sessions to be established with other entities in the communication network. After a session is established, a check is performed to determine if a subscription to be notified of events that warrants revoking the session already exists. If not, a subscription is established to be notified of events that warrant revoking the session. If during the session a notification is received indicating that an event that warrants revoking the session has occurred, the session is revoked.
