- a third party it is possible for a third party to contact a user on any one of a number of additional terminals so long as they are able to compose the terminal identifier of a first reference subscriber terminal and are aware of the code or codes for accessing the various types of additional terminals which may be associated with that first terminal.
- the example shown in Figures 1 and 2 includes the possibility of the subscriber storing terminal identifiers for accessing several different terminals or several different sorts of terminals associated with a first terminal it is to be appreciated that in other embodiments of the invention, provision may not be made to enable a third party to distinguish between different categories. In this case, only one pre-determined code would be required in order to enable a third party to access a user on his designated additional terminal.
- the switching exchange 10 it would not be necessary for the switching exchange 10 to send, at step 62, the value of the predetermined code to the data storage means 1 1, there being only one look-up table to access upon receipt of the first terminal identifier.
- the pre-determined code composed by the user of the subscriber terminal 5 need only be sent by the switching exchange 10 to the data storage means 11 if provision is made for the user of the subscriber terminal 5 to contact the user of the subscriber terminal 3 on more than additional subscriber terminal associated with that first terminal.
- a directory service database 70 for storing personal identification information, such as the name and address, of the user of the subscriber terminal 3 and associated subscriber terminal 4. Provision may be made for this database to import the terminal identifiers stored in the data storage means 11 in order that a directory listing may be generated showing, for example, the names and address of all users subscribing to the above described service and the first terminal identifier of that user.
- the directory service database may add one or more characters after the listing of each first terminal identifier to indicate whether that user has listed one or more associated subscriber terminals.
- a subscriber terminal 11 for a mobile telephone, facsimile machine and pager the listing of his first terminal identifier may be followed by the indications of "M", "F", and "P". These indications will then act to inform a person viewing the directory that that particular user could be contacted on either their mobile telephone, facsimile machine or pager, simply by composing a pre-determined code to identify the type of terminal, followed by the first subscriber identifier. This would the avoid the need to separately list each of the subscriber identifiers in a directory listing.
- access means 71 may be provided in order to enable a directory assistance operator to access and possibly alter the contents of either or both the directory service database 70 and the information stored in the data storage means 11.
- directory assistance operators may be contact from the telecommunications network 2 by users of the above described service in order that the information contained in the directory service database 70 and the data storage means 11 is current.

- the telecommunications system 100 includes the same subscriber terminals 3, 4 and 5 as shown in Figure 1.
- the subscriber terminal 4 once again, is connected to a telecommunications network by a mobile switching center 6 and associated base station 7 and 8.
- each of the switching exchanges 1 10, 111 constitute a service switching point within an intelligent network.
- Each of the service switching points are connected to a service control point 112 which, in turn, is connected to a service management system 113.
- each service switching point reacts to specific service triggers and initiates queries to the SCP over a common channel signalling network, such as the signalling system number 7 (SS7) network.
- the SCP reacts upon the query from the SSP and returns a message containing the data and instructions to complete the service.
- SS7 signalling system number 7
- a service management system is linked to the SCP and supports the administration of a customer record within the SCP.
- the SCP contains a service logic program used for providing an intelligent network service, such as that required to detect the presence of a pre-determined code and subscriber terminal identifier in a telecommunications signal, and to query a data storage means as to the "real" terminal identifier used to access the subscriber terminal in question.
- Such a service logic program is sent to the SCP from the SMS.
- the user of subscriber terminal 5 would dial a pre-determined code followed by the first terminal identifier used to communicate with the subscriber terminal 3.
- a call control function within the SSP is programmed to identify the presence of the pre- determined code and interprets this as a request for service by the intelligent network.
- the service switching function of the SSP interprets the request for the intelligent network service from the calling party and forms a standardized service for a request which it then sends to the SCP.
- the SCP receives the request and decodes it. After this, it encodes and sends a standardized response to the SSP.
- the response would include instruction for the SSP to send the first terminal identifier information, and possibly the predetermined code, sent by the user of the subscriber terminal 5 to the data storage means 1 1 in order to determine the subscriber terminal identifier of the subscriber terminal that the calling party wishes to contact.
- a request is once again formed and sent to the SCP.
- the SCP once again returns a command to the SSP and instructs it to direct the telecommunications signal originated from the subscriber terminal 5 to the intended subscriber terminal for receiving that signal.
- the instructions determining the manner in which the SCP responds to service requests from the SSPs is sent to the SCPs from the SMS. Provision may be provided, via interface means 114, for a network operator or other user to maintain and update these instruction via the SMS 1 13. In addition, access may be provided via the SMS to the contents of the data storage means 1 1.
