Abstract
Abstract A network (10) for providing cross-context connections between subscribers comprises a plurality of directory databases for storing mappings between individual names, addresses and personal identification numbers of network subscribers in a plurality of telecommunications contexts such as business, residence, cellular, etc. The network (10) also comprises a linking database comprising one entry for each subscriber. Each entry of the linking database is accessed by the personal identification number of a subscriber and contains pointers to particular ones of the directory databases where the addresses for the subscriber in different contexts can be found. For example, to set up a cross-context connection, a first subscriber (A) who knows the address of a second subscriber (B) in one context, transmits the known address to a directory controller (70). The directory controller (70) utilizes the known address as a source address and accesses a directory database to find out the personal identification number of the second subscriber. The personal identification number is then utilized by the directory controller (70) to access the linking database to determine the directory database which contains the address of the second subscriber in a desired context. The address of the second subscriber in the desired context is obtained and a connection is established between the first subscriber and the second address of the second subscriber.

Claims Analysis
Total Claims: 23
Claim 1
Independent Claim
186 words
A communications network for providing cross-context connections between subscribers comprising processing means for maintaining a first database including one entry per network subscriber, each such entry being accessible in response to a personal identification number of the corresponding subscriber and comprising a plurality of pointers to directory databases which contain addresses for the corresponding subscriber in different contexts, a directory controller located in said network and including means for communicating with the directory databases to obtain said personal identification number of a said subscriber from said databases, first transmission means for transmitting a first address of a second subscriber to said directory controller from a first subscriber so that said directory controller can obtain a personal identification number of said second subscriber from a directory database, second transmission means for enabling said directory controller to communicate with said processing means to access said first database in response to said personal identification number to obtain from said first database information relating to a different address of said second subscriber, and means for establishing a connection between said first subscriber and said second subscriber at said different address.
Claim 2
Dependent Claim
186 words
A communications network for providing cross-context connections between subscribers comprising processing means for maintaining a first database including one entry per network subscriber, each such entry being accessible in response to a personal identification number of the corresponding subscriber and comprising a plurality of pointers to directory databases which contain addresses for the corresponding subscriber in different contexts, a directory controller located in said network and including means for communicating with the directory databases to obtain said personal identification number of a said subscriber from said databases, first transmission means for transmitting a first address of a second subscriber to said directory controller from a first subscriber so that said directory controller can obtain a personal identification number of said second subscriber from a directory database, second transmission means for enabling said directory controller to communicate with said processing means to access said first database in response to said personal identification number to obtain from said first database information relating to a different address of said second subscriber, and means for establishing a connection between said first subscriber and said second subscriber at said different address.
