Abstract: A method and apparatus for selecting a data connection IP (Internet Protocol) type during roaming. At a device a comprising a processor, a memory storing data indicative of radio access technologies and associated internet protocol (IP) types to use under different roaming conditions, and a communication interface, it is determined, using the communication interface, that roaming is occurring and a given radio access technology being used in the roaming is also determined. The data is processed to select an IP type associated with the given radio access technology. Thereafter, the IP type selected is used, during the roaming, in requests to a gateway to a network.

Abstract: This document discusses, among other things, a method for heat management in a portable electronic device. The method includes measuring a current in the portable electronic device and determining, as a function of the current, whether the portable electronic device may overheat. When the portable electronic device may overheat, at least one component in the portable electronic device can be turned off.

Abstract: A touch-screen device has a processor operatively coupled to a memory for storing and executing an application, and a touch-sensitive display screen for receiving a touch input for triggering a displaying of an escape key on the display screen. The displaying of the escape key can be triggered by touching the screen for a predetermined period of time, by swiping a stylus over the screen or by any other recognizable gesture. This soft escape key can thus be used to close, or escape from, an application.

Abstract: A method of automatically detecting fiber cabling errors in an optical network is described. Fiber connectivity between optical nodes in the network, including initial cabling and any subsequent cabling changes or cabling errors, is detected. The connectivity information including initial link connectivity and changes relating to new fiber connectivity is stored. The invention automatically determines cross-connect and lightpath impact of a cabling change, detects if light paths have been automatically rerouted off affected optical links, and supports operator resolution of cabling problems.

Abstract: A method of modifying the routing of lightpaths without interrupting service, scheduling long maintenance windows or the need to delete and recreate lightpath definitions is disclosed. The solution utilizes a combination of non-disruptive bridge and roll techniques and uses temporary end to end protection or segment protection to change the routing of the working or protection part of the lightpath without having to take the lightpath out of service. The solution relies on lambda level switching hardware support and software at the two endpoint nodes to coordinate in the event of an operator-initiated protection switch, the switching of connections from the working path to the protected path. Protection switching can be configured to be end to end, single segment only or multi hop protection depending on the application.

Abstract: The invention creates a capability within the network management software application to highlight the path through the network for a selected lightpath. The user first selects a lightpath and then turns on the highlighted function. When highlighting is on the user can navigate through the network manager and visualize the lightpath shown by different colours for example dark blue for working and light blue for protection. At the network level, this enable the operator to see the routing of the path.

Abstract: The problem solved by this invention is the definition of a well defined approach for creating lightpaths that uses a combination of both operator directed routing and automatic routing and allows the operator to change, at any point during the creation of the lightpath, the wavelength for any segment of the path. The key advantage of this approach is that it allows the operator to customize the lightpath to suit special end-customer needs or special networking requirements. The operator can utilize automatic routing algorithms to provide recommended wavelength selections and routing then, in the same operation, manually reject and select different wavelengths for some or all of the wavelengths in the lightpath.

Abstract: This invention proposes a method for enabling segment protection, whereby one or more hops in the lightpath are protected by either a dedicated or shared wavelength. This provides a more cost effective solution for the service provider such that they only need to configure protection, and therefore deploy equipment, to those sensitive portions of the network rather than dedicating wavelengths and equipment for protection end-to-end for a lightpath. Further, allowing protecting wavelengths to be shared for protection, gives further flexibility and therefore, savings, to the service provider. To utilize lightpath segment protection and sharing the protection between multiple lightpaths requires the new mesh networking capabilities of the network elements and new network management tools to configure, and monitor these protected lightpaths.
