Patent number: 8295817Abstract: In one illustrative example, a technique in a server to facilitate a re-establishing of communication over a data connection between an application server and a wireless communication device which communicates via a base station of a wireless communication network is described. In response to a communication loss between the wireless device and the wireless network which causes the data connection to be terminated, the server receives from the application server a plurality of connection requests which are intended for receipt by the wireless device for re-establishing the data connection. The server operates to limit the number or a rate of the connection requests allowed to pass from the server to the base station of the wireless network during the communication loss between the wireless device and the wireless network.Type: GrantFiled: June 7, 2010Date of Patent: October 23, 2012Assignee: Research In Motion LimitedInventors: Nicholas Patrick Alfano, Noushad Naqvi, Sarmad K.

Patent number: 7747244Abstract: Several related methods and apparatus for re-establishing communication for a wireless communication device after a communication loss between the wireless device and a wireless communication network are disclosed. In one illustrative example, the wireless network broadcasts identifiers of wireless devices associated with communication losses in the wireless network over a control channel. After regaining signal coverage, a wireless device monitors the control channel to decode and compare each broadcasted identifier with an identifier of the wireless device. Based on a match between a broadcasted identifier and the identifier of the wireless device, the wireless device transmits a control message which informs the wireless network of the presence of the wireless device. Otherwise, the wireless device normally refrains from transmitting the control message to the wireless network.Type: GrantFiled: January 11, 2007Date of Patent: June 29, 2010Assignee: Research In Motion LimitedInventors: Nicholas P.
