A method and apparatus for obtaining information about an object through interaction between a mobile station (MS) and a computer network such as the Internet, and communicating the information to the MS. A digital camera obtains an image of an object, such as a geographic region proximate the MS, which is then transmitted through the mobile communications system to the computer network. A converter server such as an Optical Character Reader (OCR) server interfaced with the global computer network converts the digital image to a text format which is then compared, along with a general location identifier of the MS to geographic data stored in a location database connected to the global computer network. Based on a comparison of the converted text data and the general location identifier of the MS to the geographic data stored in the location server, a precise location of the MS is determined and transmitted to the MS.

Using alternate routes for fail-over in a communication network involves maintaining a preferred route and an alternate route in a routing table and routing protocol messages according to the alternate route when the preferred route is unavailable. A node obtains multiple routes for a destination, prioritizes the routes, and installs multiple routes in the routing table, including at least the preferred route and the alternate route. When the node receives a protocol message, the node searches the routing table for a highest priority route that is available for routing the protocol message, and routes the protocol message according to the highest priority route that is available for routing the protocol message. When a route becomes unavailable, the node updates the routing table to indicate that the route is unavailable, and may compute new routes and/or re-prioritize existing routes.

A notification system is coupled to a plurality of message services including a voice mail server, an email server and an information server in an office. Messages left for a user (e.g. voice mail, email, CRM event, etc.) are deposited in folders maintained by the messaging services. The notification system detects additions to the user's folders and when a new message arrives, the notification system sends an alert to a Wireless Access Protocol (WAP) enabled device (e.g. cell phone) configured for the user. The alert includes the total number of messages of each type received for the user, along with an indication of the most recently received message. The notification system may further monitor an information source for new information that may be of interest to the user (e.g. stock or product price quotes), and provide these in the alert notification if certain conditions are met (e.g. stock price exceeds a threshold).

A communication network comprises a plurality of nodes interconnected by communication links. A node maintains a database of topology information relating to the network. A node receives a topology advertisement from another node of the network which provides information about a part of the network. The topology advertisement includes a metric which is related to aggregate distance or cost of the path travelled by the topology advertisement. The node compares the metric in the newly received topology advertisement with one previously received for the same part of the network. The database is updated with the newly received topology advertisement if the value of the metric in the newly received topology advertisement is lower than the metric in the topology advertisement previously received for the same part of the network. The method can be used during flooding or database synchronisation. The metric can be carried within a header or body of a topology advertisement, such as a Link State Advertisement (LSA).
