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.

A system, apparatus and method automatically update address information of a user's outgoing and incoming messages to / from a communication network thereby relieving the user of the burden of manually entering address changes into a user address book. A plurality of users are coupled through terminals to a server in the communication network for exchanging telephone, CATV, Internet, intranet for messaging, facsimile, etc purposes. The server includes a message store; stored message profile; and is coupled to a change server linked to a network. The change server includes search rules and change options provided by the users in directing the change server in finding correct and alternative address information when erroneous or unknown information is detected in the outgoing and incoming messages. Each user address book includes a series of contacts for each user. Each contact is identified by an identification number, ID, including a name and address. The server detects message headers where a "Send To Address" is not in the address book. The change server is activated and accesses external databases for correct or alternative addresses in accordance with search rules provided by the user. The alternative or correct address books address information is installed in the users address book and the "Send To Message" process is executed. For returned messages incorporating erroneous information, the search server is again activated to access the databases for correct address information, after which the user's address book is updated thereby eliminating the time-consuming, irritating manual process of updating the user address book for outgoing and incoming messages.

Some embodiments provide access control by sending a series of invalid messages to a user equipment (UE) that is not authorized to access services of the second network to reject the UE. Some embodiments reject the UE by sending a message to ban a UE from an access area with a particular access area identifier.

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).

“A method of supporting mobility in an Internet Protocol (IP)-based data network. The method comprises the steps of generating a first stateful IP autoconfiguration message at a mobile node, whereby the message includes an address capable of use for routing maintenance. The mobile node transmits the generated message to a first access node, which incorporates its address and forwards the message to a dynamic host configuration protocol (DHCP) Server. The DHCP Server and access node analyse the message to determine a route to deliver data to and / or from the mobile node. One or more route update message are triggered from said access node and said DHCP server to a number of network elements between said access node and said DHCP server in the IP based data network to support mobility in an IP domain with minimum bandwidth use and minimum tunnelling required.”
