Patent number: 10110548Abstract: Systems and methods are provided for managing and delivering status notifications relating to messages transmitted between communication devices. Each communication device is provided with a status agent for detecting transmission of messages to a recipient device and receipt of messages from a sending device. Upon transmission, the status agent notifies a status service of the outbound message. Upon receipt of a message or upon the message being marked read once received, the status agent notifies the status service that the received message has been received or read accordingly. The status service then notifies the status agent of the sending device that the message has been received or read, so that the sending device's status agent can notify a corresponding messaging application. The status service operates to reconcile outbound message notification and received or read status updates for messages sent using a number of different applications or formats.Type: GrantFiled: January 6, 2012Date of Patent: October 23, 2018Assignee: BlackBerry LimitedInventors: Michael Frederick Harness Clarke, Sanjay Kalyanasundaram, Calvin Roex

Patent number: 7088436Abstract: An integrated OTDR/OSC mechanism for monitoring an optical transport system without disrupting the normal service. The invention combines two essential network components in an integrated mechanism. These components are the mandatory OSC function as part of any DWDM network, and the in-skin, in-service attributes of the OTDR engine. One pair of control wavelengtbs is sufficient to perform both OSC and OTDR functionalities. In this way, distributed control function, OTDR procedures, and fiber monitoring is achieved, while trace acquisition from anywhere in the network becomes possible. By bringing these two essential network components together, the invention allows for superior network management and reduction in maintenance costs. This is primarily due to the fact that the invention allows to use and control the OTDR engine remotely, while the combination with the OSC function allows rapid implementation of the OTDR procedures on operating channels within each fiber of a cable.Type: GrantFiled: August 30, 2001Date of Patent: August 8, 2006Inventors: Ross Alexander Saunders, Enos Avid Lemus-Tejada, Sanjay Kalyanasundaram, Meng Soo
